Fatigue After Aneurysmal Subarachnoid Hemorrhage Is Highly Prevalent in the First-Year Postonset and Related to Low Physical Fitness: A Longitudinal Study

Objective The aim of the study was to investigate whether low physical fitness and inactive and sedentary lifestyles play a role in the severity of fatigue in patients with aneurysmal subarachnoid hemorrhage (a-SAH). Design This is a prospective 1-yr follow-up study, including a total of 52 patients with a-SAH. Outcome measures included the Fatigue Severity Scale score, peak oxygen uptake (VO2peak), isokinetic knee muscle strength (peak torque), physical activity (% 24-hr period), and sedentary behavior (% waking hours) and were evaluated at 6 and 12 mos after onset. Results Fatigue was highly prevalent in the first year and reported by 48% of the patients at 6 mos and by 52% at 12 mos after a-SAH. Fatigue was associated with the knee extension (P

Maximizing Recovery From Concussions for Youth Participating in Sports and Recreational Activities

Concussions have become a public health issue. This public health concern has drawn the attention of many states in which laws were created to address concussions safety, recognition of signs and symptoms, immediate removal, medical clearance, and return-to-play protocols. Most state legislation focused on student athletes participating in organized sports. However, the rise in concussion can be directly attributed to children, youth, and adolescents participating in nonsports-related events. Maximizing recovery from a concussion involves implementing education programs that focus on recognition of symptoms, treatment, and return-to-learn options. Treatment strategies used to address concussed youth include physical and cognitive rest and minimizing external stimuli that can increase symptoms. Because learning is a direct outcome for all youth, a return-to-learn protocol based on a collaborative school-based team approach is suggested.

Relationships Between Specific Functional Abilities and Health-Related Quality of Life in Chronic Traumatic Spinal Cord Injury

Objective The objective of this study was to explore the relationships between specific functional abilities assessed from the third version of the Spinal Cord Injury Measure and health-related quality of life after a traumatic spinal cord injury. Design A prospective cohort of 195 patients who had sustained a traumatic spinal cord injury from C1 to L1 and consecutively admitted to a single level 1 spinal cord injury–specialized trauma center between April 2010 and September 2016 was studied. Correlation coefficients were calculated between Spinal Cord Injury Measure scores and Short Form 36 version 2 summary scores (physical component score; mental component score). Results The total Spinal Cord Injury Measure score correlated moderately with the physical component score in the entire cohort, correlated strongly with physical component score in tetraplegics, did not correlate with physical component score in paraplegics, and did not correlate with mental component score. Mobility subgroup and individual items scores showed the strongest correlations with the physical component score in the entire cohort, followed by self-care and sphincter management. Conclusions This work is significant being the first to determine which specific functional abilities are mostly related to health-related quality of life and highlights the differences between tetraplegic and paraplegic patients. Our findings could help clinicians to guide rehabilitation plan based on importance of specific functional abilities in relationship with the health-related quality of life.

More Than Just a Game: The Public Health Impact of Sport and Physical Activity for People With Disabilities (The 2017 DeLisa Lecture)

Although people with disabilities make up a large proportion of our global population and are known to be disproportionately impacted by sedentary lifestyles leading to chronic disease, programs promoting physical activity often fail to address their unique needs. Both environmental and attitudinal factors also act as barriers to full participation. In this context, increasing evidence shows the positive impact of physical activity and sport on outcomes related to physical health, mental health, community participation, and, in some cases, neurorecovery for people with disabilities. Thus, participation should be seen not only as a medical intervention but also as a rights-based issue. We, as physiatrists, can be agents of change by promoting concepts of universal design and inclusion in physical activity and sport programs.

The Impact of Introducing a Physical Medicine and Rehabilitation Trauma Consultation Service to an Academic Level 1 Trauma Center

Objective Previous retrospective studies suggest that early physical medicine and rehabilitation (PM&R) consultation for trauma patients improves outcome and reduces acute care length of stay (LOS). There have not been controlled studies to evaluate this impact. This study assesses the impact of PM&R consultations on acute trauma patients. Design This study compared measured outcomes before and after the introduction of a PM&R consultation service to the trauma program at a large academic hospital. The primary outcome measure was acute care LOS. Results The 274 historical controls and 76 patients who received a PM&R consultation were not different in injury severity score, age, or sex. Length of stay was not different between the two groups. However, when early (≤8 days after injury) versus late (>8 days) consults were compared, the early group had a markedly lower LOS (12 vs. 30 days, P

Electromyographic Effect of Using Different Attentional Foci During the Front Plank Exercise

Objective The aim of this cross-sectional study was to examine whether an internal focus on different core muscles during the isometric prone plank exercise increased muscle activity. Design Twenty university students performed the following five different conditions: regular prone plank (external focus) and prone plank with an internal focus on different muscles. Surface electromyography signals were recorded for the upper rectus abdominis, lower rectus abdominis, external oblique, and lumbar erector spinae. Results For the upper rectus abdominis, an internal focus on using any muscle increased activity. For the lower rectus abdominis, internal focus on any muscle except the lumbar erector spinae increased activity. No changes were found for external oblique and lumbar erector spinae activity. Conclusions Upper rectus abdominis and lower rectus abdominis activities increased during an internal focus on the abdominal muscles. external oblique and lumbar erector spinae activities were nonaffected by an internal focus on any muscle.

Individual and Environmental Determinants of Late-Life Community Disability for Persons Aging With Cardiovascular Disease

Objective The aim of the study was to estimate the prevalence of late-life community disability for adults 65 yrs and older with cardiovascular disease versus those without. This study also investigated the contributions of environmental and individual risk factors on late-life community disability for persons with cardiovascular disease. Design This is a secondary data analysis of the 2016 round of the National Health and Aging Trends Study. The study sample included community-dwelling Americans with cardiovascular disease (n = 1490) and without (n = 4819). Logistic regression was used to estimate associations between individual risk factors, environmental factors, and community disability for those with cardiovascular disease. Results Individuals with cardiovascular disease had a significantly higher prevalence of late-life community disability than those without (44.8% vs. 29.0%). For persons with cardiovascular disease, lack of transportation, home modification, and needing assistance with mobility increased the odds of community disability. Younger age and lower comorbidity were associated with decreased odds of community disability. When accounting for environmental factors in multivariate analyses, sex, race, and education were not significantly associated with community disability. Conclusion Late-life community disability is highly prevalent for persons aging with cardiovascular disease. Intervention strategies to deter late-life community disablement should focus on improving access to transportation and improving the community environment in which older adults live.

Paroxysmal Sympathetic Hyperactivity and Clinical Considerations for Patients With Acquired Brain Injuries: A Narrative Review

The term "storming" has often been used colloquially to characterize patients with brain injury who showed signs and symptoms of elevated heart rate, blood pressure, respiratory rate, temperature, and motor posturing. Recently, the term paroxysmal sympathetic hyperactivity has been used as the unifying term to describe these acute episodes of elevated sympathetic hyperactivity. Various pharmaceutical and management options are available, but no single drug or protocol has been deemed superior to the others. Data on prognosis and recovery in relation to paroxysmal sympathetic hyperactivity are limited but point toward poorer functional outcome and increased mortality. Overall, the phenomenon of paroxysmal sympathetic hyperactivity requires further research to aid rehabilitative efforts so that patients can effectively participate in therapy. A review of the literature has revealed sparse information on the management of sympathetic storming within rehabilitation facilities. This narrative review seeks to provide an up-to-date synopsis and recommendations on the management of rehabilitation inpatients with paroxysmal sympathetic hyperactivity.

Extracellular Matrix and Adhesion Molecule Gene Expression in the Normal and Injured Murine Intervertebral Disc

Objective The aim of the study was to determine the transcription profile of the mouse nucleus pulposus and annulus fibrosus with an unbiased method. Furthermore, pathophysiological relevance of selected genes was demonstrated in the mouse tail intervertebral disc injury model. Design Paired normal mouse nucleus pulposus and annulus fibrosus tissue from C57BL/6j mice was examined by a polymerase chain reaction array. Key gene expression in the normal and injured intervertebral discs was confirmed by real-time polymerase chain reaction. Results Among the 84 genes studied, 63 were expressed higher in annulus fibrosus than in nucleus pulposus; only four genes were expressed higher in nucleus pulposus than in annulus fibrosus (n = 4, P ≤ 0.05). Real-time polymerase chain reaction confirmed that cadherin (cdh) 2 gene expression was higher in nucleus pulposus than in annulus fibrosus, and type I collagen (col1) gene expression was higher in the annulus fibrosus than in nucleus pulposus (n = 8, P

A Tale of Confusion From Overlapping Confidence Intervals

In clinical research presentations, study results are commonly reported in the form of P values and confidence intervals as an estimate of association and treatment effect. The interpretation of confidence intervals that overlap can be confusing and difficult for the reader to draw clinically meaningful conclusions. In this brief report, we describe the basics of confidence intervals and present an example from a recently published randomized control trial to illustrate a common confusion that overlapping confidence intervals between the means of two independent groups may not necessarily reject the true significant difference of effect. It is recommended that investigators use the direct difference of means between groups for confidence interval estimation to reduce type II errors. Clinicians should interpret overlapping confidence intervals with caution and avoid the assumption that overlapping confidence intervals always implies a lack of difference of treatment effect to decide application of treatment.

Complete Restoration of Respiratory Muscle Function in Three Subjects With Spinal Cord Injury: Pilot Interventional Clinical Trial

Objectives The aim of this study was to assess the safety and efficacy of complete restoration of respiratory muscle function in subjects with spinal cord injury. Methods This was an interventional study investigating three subjects maintained on a diaphragm pacing system who were implanted with the spinal cord stimulation system to restore cough. Peak expiratory airflow and airway pressure generation were the primary physiologic outcome measures; an assessment of the degree of difficulty in raising secretions was the primary clinical outcome measure. Results Mean peak expiratory airflow and airway pressure generation during spontaneous efforts were 1.7 ± 0.2 L/s and 31 ± 7 cmH2O, respectively. When spinal cord stimulation was applied after pacing volume associated with the subject's maximum inspiratory effort and synchronized with the subject's maximum expiratory effort, peak expiratory airflow and airway pressure generation were 9.0 ± 1.9 L/s and 90 ± 6 cmH2O, respectively (P

Huge Bursitis and Bursal Synovial Osteochondromatosis Associated With Scapular Osteochondroma Mimicking a Giant Calcific Mass of the Chest Wall

Osteochondroma is the most common benign bone tumor, but it rarely arises from the scapula. Scapulothoracic bursitis is quite rare and osteochondroma is one of the unusual causes of this condition. Synovial chondromatosis may occur extremely uncommonly in this bursa. We reported an unusual case of scapulothoracic bursitis with synovial chondromatosis, which is caused by osteochondroma. To the best of our knowledge, there is no defined chondromatosis in the scapulothoracic bursa secondary to scapular osteochondroma in the literature.

Cryotherapy Reduces Muscle Spasticity But Does Not Affect Proprioception in Ischemic Stroke: A Randomized Sham-Controlled Crossover Study

Objective The aim of the study was to evaluate the immediate effects of cryotherapy (using an ice pack) on ankle joint position sense and the degree of spasticity after chronic hemiparetic stroke. Design We used a sham-controlled crossover design. Sixteen chronic hemiparetic patients were randomly assigned to two groups: (1) those who received cryotherapy followed by a control intervention 15 days later (cryotherapy group) and (2) those who received the control intervention followed by cryotherapy 15 days later (control intervention group). Ankle joint position sense was measured on the paretic side using a Biodex Multi-joint System 3 dynamometer before and after 20 mins of either application on the calf muscles. Lower absolute error scores were calculated for data analyses and were used to determine joint position sense. The degree of spasticity of the plantar flexor muscles was scored according to the Modified Ashworth Scale. Results Sixteen patients completed the crossover experiment; however, data analysis was successfully conducted in 15 participants. Cryotherapy reduced the degree of spasticity of the plantar flexor muscles without altering ankle joint position sense. Conclusions Cryotherapy (using an ice pack) may reduce plantar flexor spasticity without influencing proprioception.

Comparative Effects of Different Assistance Force During Robot-Assisted Gait Training on Locomotor Functions in Patients With Subacute Stroke: An Assessor-Blind, Randomized Controlled Trial

Objective The aim of the study was to compare the effects of progressive reducing assistance force versus full assistance force controlled robot-assisted gait training combined with conventional physiotherapy on locomotor functions in patients with subacute stroke. Design Inpatients with subacute stroke (N = 29; 16 men; Functional Ambulation Category score = 1 ± 0.9) were randomly assigned to one of two groups: a progressive reducing assistance force group (n = 15) or a full assistance force group (n = 14). The progressive reducing assistance force group performed robot-assisted gait training sessions from 100% assistance force at the outset to 60% assistance force at the end of the robot-assisted gait training, whereas the full assistance force group received 100% assistance force throughout the robot-assisted gait training sessions. Both groups performed robot-assisted gait training combined with conventional physiotherapy 5 days a week for 4 wks. After intervention, all patients then underwent only conventional physiotherapy 5 days a week for 4 wks of follow-up. Results The Mann–Whitney U test between-group comparisons showed that improvements were significantly greater in the progressive reducing assistance force group for the Functional Ambulation Category, knee extensors torque, and Berg Balance Scale relative to the full assistance force group, both at postintervention and at follow-up. Conclusions Progressive reducing assistance force control during robot-assisted gait training combined with conventional physiotherapy may be more beneficial for improving locomotor functions in patients with subacute stroke.

Obesity Is Associated with Increased Risk of Colectomy in Inflammatory Bowel Disease Patients Hospitalized with Clostridium difficile Infection

Abstract

Background

Obesity and inflammatory bowel disease (IBD) are associated with increased risk of Clostridium difficile infection (CDI). The effect of obesity on IBD course and development of complications is poorly understood. We performed this study to examine the effect of obesity on CDI-related morbidity and mortality in hospitalized patients with IBD.

Methods

We used data from the National Inpatient Sample across five study years (2010–2014) to identify patients ≥ 18 years hospitalized with both CDI and IBD. We compared the outcomes of in-hospital mortality, partial or total colectomy, hospital length of stay, and hospital charges between obese and non-obese IBD–CDI patients. Analysis included univariate and multivariate linear and logistic regression analyses.

Results

Of 304,298 hospitalized patients with IBD, 13,517 (4.4%) patients had CDI. Of these, 996 (7.4%) patients were obese. Obese IBD–CDI patients had a higher risk of colectomy (adjusted odds ratio, AOR 1.60, 95% CI 1.30–1.96; p < 0.001), longer hospital length of stay (difference 0.8 days, 95% CI 0.02–1.58; p = 0.04), and higher hospital charges (difference $11,051, 95% CI 1939–20,163; p = 0.02) than non-obese IBD–CDI patients, but no significant difference in mortality was found between the two groups.

Conclusions

Obesity is associated with a 60% increase in the risk of colectomy, longer hospital stay, and higher charges in IBD patients hospitalized with CDI. Further epidemiological and clinical studies are needed to confirm these findings.

DOI:10.4103/ijri.IJRI_35_18  
We report the case of a 51-year-old patient who underwent bilateral lung transplantation and presented with an unstable condition and sepsis 6 days after transplantation. The performed contrast enhanced spectral detector computed tomography (CT) using a dual-layer detector showed absence of perfusion in the left lung on iodine maps, although branches of the pulmonary artery were patent. This prompted retrospective evaluation of CT images and total venous occlusion of the left pulmonary veins was found. Here, iodine maps helped in raising conspicuity of loss of lung perfusion.

An accurate tool to detect cardiac amyloidosis

Myocardial nulling pattern in cardiac amyloidosis on time of inversion scout magnetic resonance imaging sequence – A new observation of temporal variability p. 427
Harshavardhan Mahalingam, Binita Riya Chacko, Aparna Irodi, Elizabeth Joseph, Leena R Vimala, Viji Samuel Thomson
DOI:10.4103/ijri.IJRI_84_18  
Context: The pattern of myocardial nulling in the inversion scout sequence [time of inversion scout (TIS)] of cardiac magnetic resonance imaging (MRI) is an accurate tool to detect cardiac amyloidosis. The pattern of nulling of myocardium and blood at varying times post gadolinium injection and its relationship with left ventricular mass (LVM) in amyloidosis have not been described previously. Aims: The aim is to study the nulling pattern of myocardium and blood at varying times in TIS and assess its relationship with LVM and late gadolinium enhancement (LGE) in amyloidosis. Materials and Methods: This was a retrospective study of 109 patients with clinical suspicion of cardiac amyloidosis who underwent MRI. Of these, 30 had MRI features of amyloidosis. The nulling pattern was assessed at 5 (TIS5min) and 10 (TIS10min) minutes (min) post contrast injection. Nulling pattern was also assessed at 3min (TIS3min) in four patients and 7min (TIS7min) in five patients. Myocardial mass index was calculated. Mann-Whitney U test was done to assess statistical difference in the myocardial mass index between patients with and without reversed nulling pattern (RNP) at TIS5min. Results: RNP was observed in 58% at TIS5minand 89.6% at TIS10min. Myocardial mass index was significantly higher in patients with RNP at TIS5min[mean = 94.87 g/m2; standard deviation (SD) =17.63) when compared with patients with normal pattern (mean = 77.61 g/m2; SD = 17.21) (U = 18; P = 0.0351). Conclusion: In cardiac amyloidosis, TIS sequence shows temporal variability in nulling pattern. Earlier onset of reverse nulling pattern shows a trend toward more LVM and possibly more severe amyloid load.

DOI:10.4103/jpp.JPP_59_18  
Objective: To study the effect of different classes and combinations of antihypertensive agents on arterial stiffness and central hemodynamic parameters. Materials and Methods: A cross-sectional study was conducted in 446 treated apparently healthy hypertensives. Oscillometric PWA was performed by Mobil-o-Graph (IEM, Germany) to derive cardiovascular parameters that were further analyzed in groups stratified by antihypertensive used. Study parameters were brachial hemodynamics (blood pressure (BP), heart rate, and rate pressure product); arterial stiffness (augmentation pressure, augmentation index, pulse wave velocity, total arterial stiffness, and pulse pressure amplification); and central hemodynamics (central BP, cardiac output, and stroke work). Statistical significance was kept at P < 0.05. Results: All groups were selected by matching of age, gender, and body mass index. They were comparable with major confounding factors. There was no difference between study parameters in hypertensives taking exclusive angiotensin-converting enzyme inhibitor (ACEI), calcium channel blocker (CCB), or angiotensin II receptor blocker. Multitherapy showed better hemodynamics and monotherapy showed better stiffness parameters. Addition of CCB to ACEI did not make a difference except with diastolic BP. For most comparisons, most of the results lacked statistical significance. Conclusion: Discrete PWA parameters showed no class difference in hypertensives, treated by conventional monotherapy or combination, ACEI appears to be the best drug. This also indicates that early diagnosis and blood pressure control are more important than antihypertensive used.

The aim of this study was to investigate the scientific contribution of Italian clinical research for contrast media-induced nonrenal adverse drug reactions over the last three decades. Ovid Embase, Ovid MEDLINE, Web of Science, and Cochrane Methodology Register were used as data sources to identify Italian descriptive studies, observational studies, meta-analyses, and clinical trials assessing contrast media-induced nonrenal adverse drug reactions as a safety outcome. The population of interest was men and women exposed to a contrast medium. Between 1990 and 2017, 24 original articles investigating contrast-induced nonrenal adverse drug reactions were identified. The cohort study was the most representative study design (10/24; 41.7%). The 24 studies were conducted mainly as monocenter studies (14/24; 58.3%) and without receiving funding (17/24; 70.8%). Seventeen out of 24 studies provided a level of evidence ranging from III-2 (11/24; 45.8%) to IV (6/24; 25.0%) on a Merlin scale. In total, 14 of 24 (58.3%) studies were published in a scientific journal ranked in the first quartile of their subject area. The 24 original articles mainly focused on adverse drug reactions already observed during clinical trials (i.e., idiosyncratic systemic reactions). In conclusion, during the last three decades and a burst was not observed in the Italian clinical research investigating contrast-induced nonrenal adverse drug reactions. High-quality clinical research is needed especially for procedures to prevent the onset of the aforementioned events, to identify risk factors, to minimize the risk of their occurrence, and to optimize their related prognosis.

Duodenoscope-Associated Infections: Update on an Emerging Problem

Abstract

The duodenoscope is among the most complex medical instruments that undergo disinfection between patients. Transmission of infection by contaminated scopes has remained a challenge since its inception. Notable risk factors for pathogen transmission include non-adherence to disinfection guidelines, encouragement of biofilm deposition due to complex design and surface defects and contaminated automated endoscope reprocessors. The most common infections following endoscopy are endogenous infections involving the patient's own gut flora. Exogenous infections, on the other hand, are associated with contaminated scopes and can theoretically be prevented by effective reprocessing. Pseudomonas aeruginosa is currently the most common organism isolated from contaminated endoscopes. Of note, reports of multidrug-resistant duodenoscopy-associated outbreaks have surfaced recently, many of which occurred despite adequate reprocessing. The FDA and CDC currently recommend comprehensive cleaning followed with at least high-level disinfection for reprocessing of flexible GI endoscopes. Reports of duodenoscope-related outbreaks despite compliance with established guidelines have prompted professional and government bodies to revisit existing guidelines and offer supplementary recommendations for duodenoscope processing. For the purposes of this review, we identified reports of duodenoscope-associated infections from 2000 till date. For each outbreak, we noted the organisms isolated, the number of cases reported, any possible explanations of contamination, and the measures undertaken to end each outbreak. We have also attempted to present an overview of recent developments in this rapidly evolving field.

Comparative analysis of duration of postoperative analgesia between levobupivacaine and levobupivacaine with clonidine after ultrasound-guided transversus abdominis plane block in patients undergoing lower segment cesarean section

Ranjita Acharya, Ranjita Baksi, Pratik Mohapatra

Anesthesia: Essays and Researches 2018 12(4):943-948

Background: Transversus abdominis plane (TAP) block in cesarean section is carried out by local anesthetics such as bupivacaine or ropivacaine with a limited duration of analgesia. The addition of adjuvants such as clonidine and dexmedetomidine has increased the duration of postoperative analgesia. Aims, Settings and Design: The aim of this study was to compare the duration of postoperative analgesia between clonidine and levobupivacaine (0.25%) versus levobupivacaine (0.25%) alone in the bilateral TAP block after lower segment cesarean section (LSCS). Materials and Methods: In this prospective randomized double-blind interventional study, 100 parturients undergoing elective LSCS were included in the study. Patients were randomly divided to receive either 20-ml levobupivacaine 0.25% (Group A; n = 50) or 20-mL levobupivacaine (0.25%) +1-μg/kg clonidine bilaterally (Group B; n = 50) in TAP block in a double-blind fashion. The total duration of analgesia, patient satisfaction score, postoperative visual analog scale score, total requirement of analgesics in the first 24 h, and the side effects of clonidine were observed. Statistical Analysis: Statistical tests were conducted using SPSS. P < 0.05 was considered as statistically significant. Results: A total of 92 patients were analyzed. Duration of analgesia was significantly longer in Group B (17.94 ± 0.76 h) compared to Group A (7.16 ± 0.41 h) (P < 0.001). Mean consumption of tramadol was 197.77 ± 14.90 mg and 8.889 ± 28.77 mg in Groups A and B (P < 0.001), respectively. All patients in Group B were extremely satisfied while those in Group A were satisfied (P < 0.01). None of the patients experienced hypotension or bradycardia. Conclusion: The addition of clonidine 1 μg/kg to 20-ml levobupivacaine 0.25% in TAP block bilaterally for cesarean section significantly increases the duration of postoperative analgesia, decreases postoperative rescue analgesic requirement, and increases maternal comfort compared to 20 ml of levobupivacaine 0.25% alone.

Ravi Kumar Keshri, Mukesh Kumar Prasad, Amit Kumar Choudhary, Gurdeep Singh Jheetay, Yashowardhan Singh, Kali Kapoor

Anesthesia: Essays and Researches 2018 12(4):897-902

Background: Dexmedetomidine, a selective alpha 2 (α2)-adrenergic receptor agonist, has been used to blunt the hemodynamic response associated with laryngoscopy and tracheal intubation, which is a common concern for the anesthesiologist, especially in high-risk patients and geriatric age group. Aim and Objectives: The current study is to evaluate and compare the effects of different doses of dexmedetomidine in controlling hemodynamic response during tracheal intubation in geriatric patients. Materials and Methods: After getting approval from the Ethical Committee, 90 patients of the American Society of Anesthesiologist Physical Status Classes I and II, aged ≥60 years, were randomly assigned into three groups: Group I (normal saline, n = 30), Group II – dexmedetomidine (0.50 μg/kg, n = 30), and Group III – dexmedetomidine (1.00 μg/kg, n = 30). Dexmedetomidine was infused for 10 min before induction. Data were recorded as before infusion (T0), at the end of infusion (T1), before tracheal intubation (T2), at the moment of tracheal intubation (T3) 5 min after tracheal intubation (T4), and 10 min after tracheal intubation (T5). Modified observer's assessment of alertness/sedation scale score was observed at the time of T0 and T1. All statistical analyses were done using SPSS version 22. Results: Mean systolic blood pressure was statistically significantly (P < 0.05) more among Group I compared to Group II and III at T2, T3, and T4. Mean heart rate (HR) value was significantly (P < 0.05) more among Group I compared to Group III from T1 to T5, whereas there was no significant change in HR between Group I and Group II and at T4 and T5 h was comparable in Group II and Group III. Conclusion: This study concluded that more acceptable hemodynamic changes were seen with 0.50 μg/kg dexmedetomidine when compared with 1.0 μg/kg dexmedetomidine during intubation. A lower dose besides being cost-effective is also free of side effects associated with the higher dose of 1 μg/kg dexmedetomidine.

AV Gurava Reddy, Mohammed Shafeekh, Sukesh Rao Sankineani, Khubchand Jhakotia, Muralidhar Sagi, Deepesh Daultani, Vishesh Khanna, Krishna Kiran Eachempati

Anesthesia: Essays and Researches 2018 12(4):774-777

Background: Severe acute postoperative pain after total knee arthroplasty (TKA) may cause significant morbidity to patients. Recent techniques such as peripheral nerve blocks have shown promising hope in providing appropriate pain control without systemic side effects. Adductor canal block (ACB) and multisite infiltration analgesia (MIA) are two techniques that are proven to be effective individually. Aim: This study aims to compare the efficacy of ACB versus MIA in postoperative analgesia and functional recovery after unilateral knee arthroplasty. Settings and Design: A prospective study was conducted between July 2016 and December 2016 involving 200 patients undergoing unilateral TKA. Materials and Methods: Patients were either administered MIA (Group I, n = 100 patients) or ACB (Group II, n = 100 patients). All the patients were assessed for severity of pain by visual analog scale (VAS) at 8, 24, and 48 h postoperatively and knee range of motion (ROM) at 48 h after surgery. Statistical Analysis: The Statistical Package for the Social Sciences (SPSS 19.0, SPSS Inc., Chicago, IL, USA) was used for descriptive and inferential analysis. Results: Patients who received MIA showed significantly better VAS scores 8, 24, and 48 h after surgery. Furthermore, this subset of patients showed a marginally better ROM postoperatively. However, there was no difference number of patients requiring rescue analgesia for breakthrough pain or technique-related problems between both groups. Conclusion: This study demonstrates that MIA is a safe technique that provides effective analgesia at 8, 24, and 48 h postoperatively. This leads to faster rehabilitation compared to ACB in patients undergoing TKA.

Endocavitary versus linear array high-frequency probe in ultrasound-guided supraclavicular subclavian vein central access

Maged Labib Boules

Anesthesia: Essays and Researches 2018 12(4):873-878

Background: Vascular access is a top priority in the critically ill patients. Cannulation – venous and/or arterial – is the first step in any emergency situation. Ultrasound (US)-guided vascular cannulation was found to have a higher success rate and a decreased incidence of mechanical complications as compared with the landmark one. Aim: This study aims to compare subclavian vein (SCV) access through supraclavicular (SC) approach by endocavitary (EC) probe technique versus linear array high-frequency probe technique. Settings and Design: A prospective, randomized controlled study conducted on 60 patients. Patients and Methods: Study was carried out on 60 adult patients presenting for the surgical intensive care unit in Fayoum University Hospital. Patients were classified into two groups: Group (A) (n = 30): Catheter was inserted using the EC probe and Group (B) (n = 30): Catheter was inserted using the linear array high-frequency probe. Statistical Analysis Used: Student's t-test was applied for calculation of normally distributed variables and Mann–Whitney U-test for nonnormally distributed variables. Categorical data between the groups were compared using Chi-squared test. P < 0.05 indicated a statistically significant difference. Results: The frequency of successful cannulation of the SCV at first attempt was significantly higher in Group A compared to Group B (P = 0.044). The number of attempts and the time needed for venous access were significantly lower in Group A compared to Group B (P = 0.038, <0.001 respectively). No significant difference was found regarding the incidence of posterior wall puncture, arterial puncture, or hematoma, (P = 0.671, 0.055, 1 respectively). Conclusion: The use of EC probe technique for Subclavian venous access through the SC approach significantly increased the success rate compared to the linear array high-frequency probe.

Intravenous low dose fentanyl versus lignocaine in attenuating the hemodynamic responses during endotracheal intubation: A randomized double-blind study

Ranjithkumar R Thippeswamy, Supreeth R Shetty

Anesthesia: Essays and Researches 2018 12(4):778-785

Background: The laryngotracheal stimulation is known to cause reflex sympathoadrenal response with a marked increase in heart rate and blood pressure. Arrhythmias can be precipitated. The harmful nature of this response has been noted in patients at risk. Therefore, it is important to find an effective means of attenuating sympathetic response to laryngoscopy and intubation. The present study is undertaken to determine the efficacy of intravenous low dose fentanyl (2 μg/kg) and lignocaine (1.5 mg/kg) in attenuating hemodynamic response to laryngoscopy and tracheal intubation. Aim: The aim of this study is to compare the efficacy of intravenous low dose fentanyl (2 μg/kg) versus lignocaine (1.5 mg/kg) in attenuating the hemodynamic responses during endotracheal intubation. Settings and Design: This was double-blinded randomized controlled study. Materials and Methods: After obtaining institutional ethical clearance and informed consent, a total of 90 patients, with the American Society of Anaesthesiologists Physical Status I and II scheduled for elective surgeries, were selected randomly and divided into three groups of 30 each. The general anesthesia technique was standardized for all three groups as follows: Group 1 (control-received normal saline), Group 2 (Lignocaine 1.5 mg/kg), and Group 3 (Fentanyl 2 μg/kg). Heart rate, systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure were recorded preinduction, postinduction and 1,3,5,7, and 10 min after endotracheal intubation. Statistical Analysis: Descriptive data presented as mean ± standard deviation and in percentage. Multiple group comparisons were made using one-way ANOVA followed by unpaired "t" test for pairwise comparison. "P" <0.05 was considered for statistical significance. Results: The fentanyl group showed significantly lesser rise (26%) in heart rate compared to lignocaine (33%) (P = 0.018) and control group (42.5%) (P = 0.000). The lignocaine group showed lesser rise in systolic blood pressure (14.5%) compared to control group (20%) (P = 0.000) at intubation. The fentanyl group showed a significant decrease in systolic blood pressure after administration, which came back to normal at 7 min following intubation and again decreased 10 min after intubation. Conclusion: Lignocaine and fentanyl both attenuated the rise in heart rate, though fentanyl was better. Lignocaine attenuated the rise in blood pressure with intubation whereas fentanyl prevented it totally. Of the two drugs low dose fentanyl 2 μg/kg i. v. bolus provides a consistent, reliable, and effective attenuation as compared to lignocaine 1.5 mg/kg i. v. bolus.

G Dilip Kumar, N Gnanasekar, Pranjali Kurhekar, T Krishna Prasad

Anesthesia: Essays and Researches 2018 12(4):919-923

Context: Traditional truncal blocks are devoid of visceral analgesia. Quadratus lumborum (QL) block has shown greater efficacy in providing the same. Aims: This study was done to compare the efficacy of transversus abdominal plane (TAP) block versus QL block in providing postoperative analgesia for lower abdominal surgeries. Settings and Design: This was a prospective, randomized, double-blinded study. Subjects and Methods: Seventy adult patients were randomly allocated into two groups, where Group A received TAP block with 20 ml of 0.25% ropivacaine on each side (n = 35) and Group B received QL block with 20 ml of 0.25% ropivacaine on each side (n = 35). The time of block, duration of surgery, Numerical Pain Intensity Scale (NPIS) score at the 1st, 2nd, 4th, 8th, 12th, 16th, and 24th postoperative hours, and the total analgesic drug requirements were noted and compared between the two groups. Statistical Analysis Used: Data were analyzed with SPSS version 23 (IBM corporation, Armonk, NY, USA) with independent t-test and Chi-square test as appropriate. P < 0.05 was considered statistically significant. Results: The time for first analgesic requirement was 243.00 ± 97.36 min and 447.00 ± 62.52 min and the total analgesic consumption (morphine in mg) was 5.65 ± 1.55 and 3.25 ± 0.78 in Group A and Group B, respectively, both of which were statistically significant (P < 0.01). There was a significant difference in postoperative pain scores (NPIS scale 0–10) at rest, between the two groups, up to 16 h. Conclusions: Patients who received QL block had a significant improvement in postoperative pain relief with reduced consumption of opioids.

Ghanshyam Kumar Sahu, Dharam Singh Meena, Suman Saini, Ajisha Aravindan, Priyankar Kumar Datta

Anesthesia: Essays and Researches 2018 12(4):786-791

Background: This study was conducted to compare the analgesic efficacy of 10 ml versus 20 mL of 0.5% ropivacaine in nerve stimulator guided interscalene brachial plexus block, in patients undergoing arthroscopic shoulder surgery. Methods: A total of 70 American Society of Anesthesiologists physical status classes 1 and 2 patients, aged 18–65 years, undergoing unilateral arthroscopic shoulder surgery, were randomized into two groups. Group A received single shot inter-scalene block with 20 mL of 0.5% ropivacaine whereas Group B received the same with 10 mL. The primary outcome was difference in the total postoperative fentanyl consumption over 24 h. Secondary outcomes were difference in block onset, intra-operative hemodynamic parameters, intra-operative fentanyl consumption, duration of effective analgesia, visual analogue scale (VAS) scores at various time intervals, duration of motor block, and incidence of hemidiaphragmatic (HD) palsy. Results: Total 24 h fentanyl consumption was significantly higher in Group B (558 ± 112 mcg) compared to Group A (296 ± 88 μg). Block onset was slower in Group B than Group A. There was no difference in intra-operative fentanyl consumption. Postoperative VAS scores were significantly higher in Group B compared to Group A, at 6 h and thereafter. Duration of motor block was significantly shorter in Group B (6.25 ± 1.25 h) compared to Group A. HD palsy was seen in all the cases in both the groups. Conclusion: Single shot nerve stimulator guided interscalene block with 10 ml of 0.5% ropivacaine was inferior to 20 mL of 0.5% ropivacaine with respect to postoperative analgesic efficacy.

Evaluation and comparison of clonidine and dexmedetomidine for attenuation of hemodynamic response to laryngoscopy and intubation: A randomized controlled study

Sana Yasmin Hussain, Abhijit Karmarkar, Dhruv Jain

Anesthesia: Essays and Researches 2018 12(4):792-796

Background: Laryngoscopy and tracheal intubation are noxious stimuli which evoke a transient but marked sympathetic response. Alpha-2 adrenoceptor agonists attenuate the sympathoadrenal responses by inhibiting noradrenaline release. Aim: This study aims to evaluate and compare the effect of intravenous dexmedetomidine and clonidine on cardiovascular response resulting from laryngoscopy and endotracheal intubation. Settings and Design: This was a prospective randomized controlled study carried out in the operating room. Materials and Methods: Ninety American Society of Anesthesiologists Physical Status I and II patients were randomly allocated into three groups, that is, Group C (clonidine 2 μg/kg), Group D (dexmedetomidine 1 μg/kg), and Group S (normal saline) infused over 10 min. Blood pressures – systolic (SBP) and diastolic (DBP), mean arterial pressure (MAP), and heart rate (HR) were recorded after drug administration and intubation at subsequent intervals. Statistical Analysis Used: Quantitative data were analyzed using ANOVA test (with post hoc Bonferroni correction for intragroup comparison). Qualitative data were analyzed using Chi-square test. P < 0.05 was considered statistically significant. Results: HR, SBP, DBP, and MAP were lower in Group C and D compared to Group S at all times measured. HR was significantly lower in Group D compared to Group C after drug infusion. At 1 min after intubation, SBP and MAP were lower in Group D compared to Group C. At 3, 5, and 10 min after intubation, SBP, DBP, and MAP were lower in Group D compared to Group C. Conclusion: There was significant reduction in hemodynamic response by dexmedetomidine and clonidine as compared to controls. Furthermore, attenuation of the pressor response to intubation was better following premedication with dexmedetomidine than with clonidine.

Anesthesia: Essays and Researches 2018 12(4):885-890

Background: Postoperative sore throat (POST) is a known complication following general anesthesia requiring endotracheal intubation. Its incidence ranges from 21% to 65% and remains the eighth most undesirable postoperative event. Various measures have been tried to decrease the incidence of sore throat with various success rates. Aim: This study aimed at reducing the incidence of POST with ketamine and magnesium sulfate nebulization. Settings and Design: This study is a prospective randomized, double-blinded study. Materials and Methods: After Institutional Ethics Committee approval and written informed consent, 80 patients who fulfilled the inclusion and exclusion criteria were randomly divided into two groups to receive magnesium sulfate 250 mg in 5 ml saline in Group A and ketamine 50 mg in 5 ml saline nebulization in Group B before the start of general anesthesia. All patients received standard anesthesia protocol. After extubation, all patients were enquired about the incidence and severity of sore throat at 0, 2, 4, 6, and 24 h. Statistical Analysis Used: Paired t-test and Wilcoxon signed-rank test were used to compare hemodynamic variables and Chi-square test to compare the incidence and severity of sore throat. Results: There were no differences in the demographic profile, duration of laryngoscopy, time taken to intubate, and duration of surgery between the two groups. The incidence and severity of sore throat were significantly decreased in ketamine group at 4 and 6 h when compared to magnesium sulfate group. Conclusion: Nebulization with ketamine 50 mg significantly decreases the incidence of POST when compared to magnesium sulfate 250 mg.

Shraddha Vidyadhar Naik, Vithal Krishna Dhulkhed, Rewa Hemant Shinde

Anesthesia: Essays and Researches 2018 12(4):797-802

Background: The operation theater (OT) complex is a costly component of a hospital budget expenditure. This area of hospital activity requires maximum utilization to ensure optimum cost benefit. To achieve a high level of utilization in the OT, it is necessary to efficiently coordinate number of activities and personnel. Methods: This study was conducted in a 1000-bedded tertiary care teaching hospital in rural maharashtra over aperiod of two months. The OT complex consists of eight major OTs. Normal working hours for routine scheduled cases on all working days except Sundays and public holidays. Results: Total study period consisted of 96 working days. There were a total of eight OT tables of various specialties, and parameters were observed during the routine hours excluding Sundays and holidays. The total procedure time was maximum for ENT followed by orthopedics and least for obstetrics. Room turnover time was maximum for obstetrics followed by general and oncosurgery. Case delays were maximum in general surgery and least for ophthalmology. The most common reason for delay in starting the operation table was patient getting shifted late from the ward and administrative causes. The most prominent reasons for cancellation were lack of operating room time followed by medical reasons of the patient. Conclusion: We concluded that most of the causes of delays and cancellations of surgeries were avoidable with proper preoperative planning and optimization of patients and resources and good communication between surgeon anesthesiologists and the nursing staff.

Practice pattern of fresh gas flow and volatile agent choices among anesthesiologists working in different Indian hospitals: An online survey

Mayank Kumar, Mamta Sinha, Habib Md Reazaul Karim, Chinmaya Kumar Panda, Subrata Kumar Singha

Anesthesia: Essays and Researches 2018 12(4):907-913

Background: Fresh gas flow (FGF) during volatile inhalational agent-based anesthesia is a concern for many reasons. Advancement in anesthesia workstation (WS) and monitoring of anesthesia gas concentrations has led to the feasibility of lower flow safely. However, the practice pattern is not yet well known. The information can help us in better protocol formation. Aim: The survey was aimed to know the prevailing practice pattern of FGF and volatile agent choices and compare them among anesthesiologists of different working setups and experiences. Materials and Methods: With approval, the present cross-sectional survey was conducted using SurveyMonkey® software from January 2018 to May 2018. Anesthesiologists working in different organizations across India were approached through E-mail and WhatsApp. Anonymous responses were collected, expressed in number and percentage scale, as well as compared using INSTAT software and appropriate tests; P < 0.05 was considered statistically significant. Results: A total of 251 (15.2%) responses were received and 249 were analyzed. Overall, 87% of respondents were using anesthesia WS and 71% were using nitrous oxide as balance gas. The FGF of <600 mL/min was highest with desflurane. Minimum alveolar concentration (MAC) monitoring was very poor in nonteaching (NT) hospitals as compared to teaching hospitals; P < 0.0001. The Boyle's machine was more common in use in NT hospitals as compared to medical colleges and corporate hospitals; P < 0.0001. Conclusion: Low-flow anesthesia (LFA) use is still suboptimal, and there are ample opportunities to increase and optimize the FGF used. The use of Boyle's machine is associated with higher flow use. MAC monitoring and LFA use are poor in NTs.

The effect of intravenous dexamethasone on intraoperative and early postoperative pain in lumbar spine surgery: A randomized double-blind placebo-controlled study

Mamta Sharma, Shikha Gupta, Shobha Purohit, Amit Kumar Goyal

Anesthesia: Essays and Researches 2018 12(4):803-808

Background: The surgical procedures of spine are generally associated with intense pain in the postoperative period. Opioids are commonly used for perioperative analgesia but are associated with many side effects. Co-analgesic drugs are used to decrease these side effects. One such supplemental drug is dexamethasone. Its strong anti-inflammatory effect contributes to perioperative analgesia. Aim: This study was done to evaluate the effect of intravenous (i.v.) dexamethasone on intraoperative and early postoperative pain in lumbar spine surgery. Settings and Design: This was a hospital-based randomized, double-blind, placebo-controlled study, done between June 2016 and December 2016 after permission of institutional ethical committee. Materials and Methods: This Study was conducted on 60 patients undergoing lumbar spine surgery, and randomization was done in two groups. Group A (study) received dexamethasone 2 ml (8 mg) i.v. and Group B (control) received 2 ml normal saline. Anesthesia technique and rescue analgesia regimen were standardized. Intraoperative pain was assessed by hemodynamic variability and postoperative pain by verbal rating score. All the quantitative data were analyzed using Student's t-test and all the qualitative data using Chi-square test. Results: Heart rate in the control group was significantly higher than the study group during intraoperative period. Mean pain scores in the early postoperative period were significantly higher in control group than the study group (P < 0.001). Mean time of first rescue analgesic in the postoperative period was 149.17 min and 34.33 min in the study group and control group, respectively (P < 0.001). Conclusion: Hence, we conclude that administration of 8 mg of preoperative i.v dexamethasone was effective in reducing intraoperative and early postoperative pain in the lumbar spine surgery.

Tunneling does not prevent dislodgment of epidural catheters: A randomized trial

Hussein Y Abukhudair, Esam N Farhoud, Khalid M Abufarah, Abdullah T Obaid, Ola A Yousef, Aqel M Aloqoul

Anesthesia: Essays and Researches 2018 12(4):930-936

Background: Epidural analgesia is preferred in postoperative pain control, but dislodgment is a major factor for failure. Tunneling is well known to control displacement of catheters. In this study, we evaluated if we can depend on tunneling in preventing dislodgment of epidural catheters. Aims: The aim is to study if tunneling is effective and safe in reducing the rate of epidural catheters' dislodgment. Setting and Design: The study was carried out at a single tertiary cancer center. The trial was parallel, simple randomized, controlled, and single blind. Allocation of treatments was generated using random number tables. Subjects and Methods: Two hundred patients undergoing major surgeries were randomized. Epidural catheters were affixed to the skin through subcutaneous tunneling to a length of 5 cm or using standard adhesive tape without tunneling. Patients were on follow-up for 6 days postsurgery according to policy. Statistical Analysis Used: Categorical variables were analyzed by Chi-square and Fisher's exact test. Student t-test was used for continuous variables. Results and Conclusion: A total of 200 patients were randomized, 92 patients received tunneled catheters and 108 received nontunneled catheters. Patients were between 20 and 85 years; 63% were male. The mean days of epidural analgesia were similar in both groups (2.7 compared to 2.5 days). About 7.6% of epidurals were dislodged in the tunneled group compared to 10.2% in the nontunneled group (P = 0.699). No differences were identified in the incidence of pain or adverse events between the groups. Tunneling did not improve the rates of dislodgment in epidural catheters. There were no safety concerns associated with tunneling epidural catheters.

Addition of dexmedetomidine to ropivacaine in subcostal transversus abdominis plane block potentiates postoperative analgesia among laparoscopic cholecystectomy patients: A prospective randomized controlled trial

B Sarvesh, BT Shivaramu, Kanchan Sharma, Amit Agarwal

Anesthesia: Essays and Researches 2018 12(4):809-813

Context: Laparoscopic cholecystectomy is associated with moderate intensity postoperative pain especially in the early postoperative period. Transversus abdominis plane (TAP) block has been shown to reduce pain scores and analgesic requirements after abdominal surgery. Aims: We hypothesized that a subcostal TAP block with ropivacaine and dexmedetomidine will prolong the duration of postoperative analgesia following laparoscopic cholecystectomy. Settings and Design: This prospective, randomized study was done in 60 patients undergoing laparoscopic cholecystectomy surgery done at a tertiary care institution. Subjects and Methods: Sixty patients undergoing laparoscopic cholecystectomy were randomized into two groups to receive either bilateral ultrasonography-guided subcostal TAP blocks with 18 mL 0.375% ropivacaine and 2 ml of normal saline (n = 30, Group R) or 18 ml. 375% ropivacaine with 0.5 μg/kg dexmedetomidine 2 mL (n = 30, Group RD). Numerical rating scale was measured postoperatively to primarily assess the pain severity and analgesic requirement for the first 24 h, hemodynamic parameters, and adverse effects were recorded. Statistical Analysis Used: Categorical data were analyzed using Chi-square test/Fisher's exact test and quantitative data were analyzed using Student's t-test and the Mann–Whitney U-test. Results: The study group (Group RD) had significantly prolonged postoperative analgesia (485.6 min) as compared to Group R (289.83 min). Moreover, consumption of morphine over 24-h period is significantly less in Group RD (14.5 mg) as compared to Group R (28.5 mg). Conclusions: Addition of dexmedetomidine to ropivacaine in TAP block prolongs postoperative analgesia and reduces opioid consumption without any major adverse effects.

Pantoea dispersa it the next emerging “monster” in our intensive care units? A case report and review of literature

Mridul Panditrao, Minnu Panditrao

Anesthesia: Essays and Researches 2018 12(4):963-966

Hospital-acquired infections and their consequences are the main cause of morbidity/mortality in critically ill and immunocompromised patients. It becomes interesting when an unusual and uncommon microorganism is found to be the causative agent, rather than the known commensals and opportunists. We present such a case, when a multiparous female, in post lower uterine segment cesarean section period presented with fulminant septic shock, hepatic failure, coagulopathy, and ventilator-associated pneumonitis. The organism grown in the tracheal secretions turned out to be an uncommon, unusual Gram-negative Coccobacillus by the name of Pantoea dispersa, resistant to almost all the conventional antimicrobial agents. In spite of all the efforts, the patient could not be saved. However, the case has opened up a virtual "Pandora's box" of questions. Are these microorganisms, known plant pathogens, really harmful to humans? Are they commensals or virulent opportunists? Are we once again on the way to a new "Acinetobacter," like near-epidemic? This is an attempt to try and find some insight about this presently uncommon and not well known genus of Pantoea! We have tried to trace and review the related available literature in the clinical medicine.

Topographic sonoanatomy of infraclavicular brachial plexus: Variability and correlation with anthropometry

Abhyuday Kumar, Ajeet Kumar, Chandni Sinha, Chhavi Sawhney, Rajnish Kumar, Debesh Bhoi

Anesthesia: Essays and Researches 2018 12(4):814-818

Objective: The aim of the study was to assess the effectiveness of ultrasound in analyzing topographic relationship of nerve cords with axillary artery at lateral infraclavicular level, their variations, and the distance from the skin and to correlate findings with anthropometric parameters. Materials and Methods: Two hundred patients aged 18–75 years were enrolled for the study after informed written consent. A 7–12 MHz linear ultrasonic transducer was used for scanning of the brachial plexus at lateral infraclavicular fossa. The results of the cord positions were expressed on a 12-section pie chart, and the number of arteries and veins was reported. Measurements included the vertical distance from the upper part of the artery to the skin, diagonal distance to the apical corner of the ultrasound image, and distances from center of cords to the center of artery. Age, sex, weight, height, body mass index, and biceps girth were recorded. Data were expressed as mean with standard deviation or frequency and percentage for categorical variables, and statistical analysis was done using correlation analysis and two-sample t-test. Results: The most frequent positions of the cords were observed in 2–4 sections (92%) for the medial cord, 6–7 sections (92%) for the posterior cord, 10–11 sections (89%) for the lateral cord, and 4–5 sections (95%) for the axillary vein. More than one axillary vein was seen in 12.5% and two axillary arteries were seen in 1.5% of cases. Cord visibility and distance between artery and apical corner of the ultrasound image correlated with anthropometric parameters. Conclusions: A topographical study of brachial plexus at lateral infraclavicular fossa showed anatomical variations and abnormal vascular formations. This sonoanatomic knowledge can be helpful in improving safety and success of nerve blocks.

Rajesh Kesavan, Sunil Rajan, Lakshmi Kumar

Anesthesia: Essays and Researches 2018 12(4):769-773

Background: Labor analgesia has been shown to have few undesirable effects on the course and outcome of the labor as well as on the fetal well-being. Aims: This study aims to assess neonatal outcome following lumbar epidural analgesia with intermittent boluses of 0.1% bupivacaine with fentanyl. The secondary objectives included assessment of maternal analgesia, complications, and outcome of labor. Setting and Design: Prospective observational study conducted at a tertiary care teaching institute. Subjects and Methods: Sixty-three patients for labor epidural analgesia were recruited. Epidural catheter was inserted in L4–L5 or L3–L4 interspace. After confirmation of the position of catheter, 3 mL of 0.5% bupivacaine with 20 μg of fentanyl made to 15 mL was administered. After 30 min, efficacy of analgesia was assessed by visual analog scale (VAS). The same bolus dose was repeated after 90 min if the patient complained of pain. A maximum of five top-up doses were allowed. Statistical Test Used: Mean and standard deviation, number and percentage Results: After 30 min of first bolus dose, 93.3% had VAS score of <4. More than 90% patients had adequate analgesia till 4th epidural bolus. During contraction stress test, only two fetuses had late deceleration. About 80% and 98.3% newborns had Apgar of >7 at 1 and 5 min, respectively.

Clinical audit on the practice of documentation at preanesthetic evaluation in a specialized university hospital

Yophtahe B Woldegerima, Semira D Kemal

Anesthesia: Essays and Researches 2018 12(4):819-824

Background: Performing preanesthetic evaluation, documenting, and keeping readily accessible record are responsibilities of anesthetists. Documentation can improve overall patient outcome. It also has an irreplaceable role in medico-legal aspects. Documentation is one of the challenges of providing quality care. Aim: The aim of this study was to evaluate the quality of documentation practice during preanesthetic visits. Materials and Methods: This clinical audit was conducted in the University of Gondar Hospital. Predefined 22 practice quality indicators were prepared according to modified global quality index. Statistical Analysis: Descriptive statistics was performed using SPSS version 20. Results: A total of 122 preanesthetic evaluation tools (PAETs) were reviewed. None of PAETs found fully completed according to the indicators. Trends differ between elective and emergency conditions. Indicators with high completion rate (>90%) were signed a consent, medical history, history of medication, allergy, anesthesia and surgery, cardiopulmonary examination, airway examination, preoperative diagnosis, and planned procedure. Anesthetic plan, vital signs, a name, per-oral status, premedication, and age were found with below average (<50%) completion rate. Conclusions: Documentation practice during the preanesthetic visit was below the standard. Unclear instructions should be replaced with standardized contents. Providing regular trainings on clinical documentation for students and staffs, and introducing modern electronic-based documentation system and preanesthetic clinics may improve the practice.

Comparison between colloid preload and coload in bone cement implantation syndrome under spinal anesthesia: A randomized controlled trial

Ayca T Dumanlı Özcan, Elvin Kesimci, Cemile Altın Balcı, Orhan Kanbak, Hülya Kaşıkara, Abdulkadir But

Anesthesia: Essays and Researches 2018 12(4):879-884

Background: Bone cement implantation syndrome (BCIS) is characterized by hypoxia hypotension cardiac arrest. There is not any research that investigated the hemodynamic effects of colloid use during and before cement implantation regarding BCIS development. Aims: We aimed to compare the effects of colloid preloading before or coloading simultaneously at cement implantation on BCIS development and hemodynamic parameters in patients who underwent total knee arthroplasty. Settings and Design: This is a prospective, randomized, clinical trial with the participation of 109 patients over 60 years of age and patients physical status American Society of Anesthesiologists Classes I and II to undergo knee surgery. The patients were administered spinal anesthesia, divided into three groups. Subjects and Methods: The patients in Group I were infused 8 mL/kg hydroxyethyl starch (130/0.4) 20 min before the cement implantation, those in Group II were infused the same simultaneously during cement implantation. Group III was infused 8 mL/kg/h sodium chloride during the anesthesia management. Hemodynamic parameters of the patients were recorded at before and after cement implantation and once the tourniquet was removed. Statistical Analysis Used: The descriptive statistics were presented as the mean ± standard deviation for normally distributed variables, as the median for nonnormally distributed variables, and as the number of cases and (%) for nominal variables. Pearson's Chi-square test and Fisher's exact test were used in the analysis of categorical variables. Results: Compared to the control group, Groups I and II were hemodynamically more stable. The development of moderate hypoxia during cement implantation was significantly different between the study groups (P < 0.05). Conclusions: We suggest that avoiding intravascular volume depletion by using the colloids, particularly in elderly patients, is important for preventing from the BCIS.

A Strategy To Exploit Surrogate Sire Technology in Livestock Breeding Programs

In this work, we performed simulations to develop and test a strategy for exploiting surrogate sire technology in animal breeding programs. Surrogate sire technology allows the creation of males that lack their own germline cells, but have transplanted spermatogonial stem cells from donor males. With this technology, a single elite male donor could give rise to huge numbers of progeny, potentially as much as all the production animals in a particular time period. One hundred replicates of various scenarios were performed. Scenarios followed a common overall structure but differed in the strategy used to identify elite donors and how these donors were used in the product development part. The results of this study showed that using surrogate sire technology would significantly increase the genetic merit of commercial sires, by as much as 6.5 to 9.2 years' worth of genetic gain compared to a conventional breeding program. The simulations suggested that a strategy involving three stages (an initial genomic test followed by two subsequent progeny tests) was the most effective of all the strategies tested. The use of one or a handful of elite donors to generate the production animals would be very different to current practice. While the results demonstrate the great potential of surrogate sire technology there are considerable risks but also other opportunities. Practical implementation of surrogate sire technology would need to account for these.

Repeats of Unusual Size in Plant Mitochondrial Genomes: Identification, Incidence and Evolution

Plant mitochondrial genomes have excessive size relative to coding capacity, a low mutation rate in genes and a high rearrangement rate. They also have abundant non-tandem repeats often including pairs of large repeats which cause isomerization of the genome by recombination, and numerous repeats of up to several hundred base pairs that recombine only when the genome is stressed by DNA damaging agents or mutations in DNA repair pathway genes. Early work on mitochondrial genomes led to the suggestion that repeats in the size range from several hundred to a few thousand base pair are underrepresented. The repeats themselves are not well-conserved between species, and are not always annotated in mitochondrial sequence assemblies. We systematically identified and compared these repeats, which are important clues to mechanisms of DNA maintenance in mitochondria. We developed a tool to find and curate non-tandem repeats larger than 50bp and analyzed the complete mitochondrial sequences from 157 plant species. We observed an interesting difference between taxa: the repeats are larger and more frequent in the vascular plants. Analysis of closely related species also shows that plant mitochondrial genomes evolve in dramatic bursts of breakage and rejoining, complete with DNA sequence gain and loss. We suggest an adaptive explanation for the existence of the repeats and their evolution.

Composition of the Survival Motor Neuron (SMN) Complex in Drosophila melanogaster

Spinal Muscular Atrophy (SMA) is caused by homozygous mutations in the human survival motor neuron 1 (SMN1) gene. SMN protein has a well-characterized role in the biogenesis of small nuclear ribonucleoproteins (snRNPs), core components of the spliceosome. SMN is part of an oligomeric complex with core binding partners, collectively called Gemins. Biochemical and cell biological studies demonstrate that certain Gemins are required for proper snRNP assembly and transport. However, the precise functions of most Gemins are unknown. To gain a deeper understanding of the SMN complex in the context of metazoan evolution, we investigated its composition in Drosophila melanogaster. Using transgenic flies that exclusively express Flag-tagged SMN from its native promoter, we previously found that Gemin2, Gemin3, Gemin5, and all nine classical Sm proteins, including Lsm10 and Lsm11, co-purify with SMN. Here, we show that CG2941 is also highly enriched in the pulldown. Reciprocal co-immunoprecipitation reveals that epitope-tagged CG2941 interacts with endogenous SMN in Schneider2 cells. Bioinformatic comparisons show that CG2941 shares sequence and structural similarity with metazoan Gemin4. Additional analysis shows that three other genes (CG14164, CG31950 and CG2371) are not orthologous to Gemins 6-7-8, respectively, as previously suggested. In D. melanogaster, CG2941 is located within an evolutionarily recent genomic triplication with two other nearly identical paralogous genes (CG32783 and CG32786). RNAi-mediated knockdown of CG2941 and its two close paralogs reveals that Gemin4 is essential for organismal viability.

Sae2 antagonizes Rad9 accumulation at DNA double-strand breaks to attenuate checkpoint signaling and facilitate end resection [Genetics]

The Mre11-Rad50-Xrs2NBS1 complex plays important roles in the DNA damage response by activating the Tel1ATM kinase and catalyzing 5′–3′ resection at DNA double-strand breaks (DSBs). To initiate resection, Mre11 endonuclease nicks the 5′ strands at DSB ends in a reaction stimulated by Sae2CtIP. Accordingly, Mre11-nuclease deficient (mre11-nd) and sae2Δ mutants...

Current indications and yield of endoscopic ultrasound and ancillary techniques in pancreatic cystic neoplasms

Abstract

An increase in the diagnosis of pancreatic cystic neoplasm has been described lately. Surgical treatment or surveillance is advised depending on the type of lesion diagnosed. The most accurate diagnostic approach is needed to make the best therapeutic decision. Endoscopic ultrasound is a very valuable tool in the evaluation of pancreatic cystic neoplasm. It generates high-quality images and allows the possibility of sampling the cystic fluid for cytology, microbiological and molecular evaluation. Even with this evaluation, the sensitivity of this approach is not always adequate. New technological resources have been developed to try to improve the diagnostic accuracy of pancreatic cystic neoplasms. The two most promising techniques are needle-based confocal laser endomicroscopy and contrast-enhanced harmonic endoscopic ultrasound. Needle-based confocal laser endomicroscopy allows a microscopic evaluation of mucosal glands and vascular pattern, to differentiate mucinous from non-mucinous lesions. Contrast-enhanced harmonic endoscopic ultrasound is used for the vascular evaluation of the microcirculation of the cyst wall and mural nodule, mainly to make the difference between malignant nodules and mucus plugs. A combination of these different diagnostic techniques can improve the diagnostic accuracy of pancreatic cystic neoplasms to offer the adequate therapeutic decision.

The difference in erosive food consumption between the case and control groups was significant (P < 0.05). There was no erosive effect of acidic food when consumed as a main meal or a snack (P > 0.05). Although there was no difference between stimulated saliva flow rate and buffering capacity between groups, the difference between the resting saliva flow rates and pH values was significant (P < 0.05). Although some wear was seen on buccal/labial surfaces of teeth, cervical and occlusal/incisal surfaces were scored higher. No TW was observed on palatal/lingual surfaces. The cervical surfaces of mandibular premolars and incisal surfaces of anterior teeth were most affected. Conclusion: Of the factors investigated, TW in the case group was correlated with consumption of acidic foods, lower salivary flow rate, and pH.

In the comparison of the survival period after surgery, the mean survival period of the APR group was 6.2 months (range, 1–16 months) while that of the LE group was 19.6 months (range, 7–43 months). Conclusion: LE with adjuvant radiation seems to offer good locoregional control without reducing the survival and may be an option of treatment for patients with small, superficial AM. However, APR should be offered for patients with locally advanced disease or as a salvage following recurrence.

He underwent excision biopsy of the tumor in both eyes performed 1 month apart. A histopathologic diagnosis of the Rosai–Dorfman disease with focal areas of rhabdomyoblastic differentiation was made. He was treated postoperatively with a course of oral steroids with close observation for the rhabdomyoblastic differentiation. Rosai–Dorfman disease is an uncommon disease and has been reported to coexist with other pathologies. We highlight focal myoblastic differentiation within the excised tissues which may not necessarily warrant a diagnosis of rhabdomyosarcoma. Long-term follow-up of this patient is required to establish the safety of observation.
