The Bold and the Beautiful: a Neurotoxicity Comparison of New World Coral Snakes in the Micruroides and Micrurus Genera and Relative Neutralization by Antivenom

Abstract

Coral snake envenomations are well characterized to be lethally neurotoxic. Despite this, few multispecies, neurotoxicity and antivenom efficacy comparisons have been undertaken and only for the Micrurus genus; Micruroides has remained entirely uninvestigated. As the USA’s supplier of antivenom has currently stopped production, alternative sources need to be explored. The Mexican manufacturer Bioclon uses species genetically related to USA species, thus we investigated the efficacy against Micrurus fulvius (eastern coral snake), the main species responsible for lethal envenomations in the USA as well as additional species from the Americas. The use of Coralmyn® coral snake antivenom was effective in neutralizing the neurotoxic effects exhibited by the venom of M. fulvius but was ineffective against the venoms of Micrurus tener, Micrurus spixii, Micrurus pyrrhocryptus, and Micruroides euryxanthus. Our results suggest that the Mexican antivenom may be clinically useful for the treatment of M. fulvius in the USA but may be of only limited efficacy against the other species studied.

Engineering Dental Implants

Abstract

Purpose of Review

Implant dentistry is traditionally viewed as a clinical subject. However, the integration of a foreign metallic structure into a living bone involves several engineering considerations. This paper aims at reviewing and discussing recent basic issues and developments pertaining to the engineering aspects of dental implant development.

Recent Findings

We consider the three components of the system, namely the implant itself, the bone, and their interaction. We start with the implant material and its geometrical and surface condition parameters. Next, we discuss the long-term mechanical survivability of the implant, namely its resistance to fatigue cracking, outlining the uncertainty on the applied loads, and surrounding atmosphere. Following a summary of the jawbone from a mechanical standpoint, we discuss the dental implant-bone interaction, as modeled analytically or numerically, with emphasis on the bone damage and evolution. The contribution of high resolution observations to enriched numerical simulations is discussed.

Summary

Progress in both experimental characterization techniques and numerical simulation methods brings engineering and dentistry closer, allowing for more focused clinical work that will ultimately lead to personalized implant dentistry.

Breast cancer subtype and stage are prognostic of time from breast cancer diagnosis to brain metastasis development

Abstract

Breast cancer brain metastasis (BCBM) is associated with high morbidity and mortality. Patients with breast cancer risk factors associated with rapid development of BCBM could potentially benefit from early brain metastasis screening. We retrospectively reviewed all BCBM patients treated with brain radiotherapy at our institution from 1997 to 2015. Interval time to BCBM was defined as date of pathologic breast cancer diagnosis to date of radiographic evidence of brain metastasis. Patients were stratified by breast cancer molecular subtype and stage at diagnosis. Kaplan Meier analysis was conducted on time to development of BCBM. Breast cancer risk factors were correlated with time to BCBM on Cox proportion hazard analysis. The study cohort comprised 121 BCBM patients, with median interval time to BCBM of 46 months. Times to BCBM for Her2+/2HR+, Her2+, Her2−/HR+, and triple-negative (TNBC) subtypes were 70, 44, 42, and 28 months respectively (p = 0.002). Time to BCBM for stages I, II, III, and IV were 70, 54, 29, and 24 months, respectively (p = 0.000). BCBM patients were further stratified by both molecular subtype (TNBC vs. non-TNBC) and stage (I, II vs. III, IV). Median times to BCBM for non-TNBC/stage I–II, TNBC/stage I–II, non-TNBC stage III–IV, and TNBC/stage III–IV were 68, 47, 29, and 6 months respectively (p = 0.000). Subtype and stage were associated with shorter time to BCBM on multivariate analysis. Subtype and initial stage are independently correlated with decreased time to development of BCBM. Patients with advanced high stage and triple negative breast cancer develop brain metastases significantly earlier.

Tractography guides the approach for resection of thalamopeduncular tumors

Abstract

Background

Thalamopeduncular tumors arise at the junction of the inferior thalamus and cerebral peduncle, and present with a common clinical syndrome of progressive spastic hemiparesis.

Method

Formal preoperative magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) were performed. Postoperative MRI was obtained to evaluate the extent of tumor resection. A prospective analysis of clinical outcomes was then conducted by the senior author.

Conclusions

Preoperative tractography is a useful adjunct to surgical planning in tumors that displace motor pathways. Gross total resection of pilocytic astrocytomas usually results in cure, and therefore should be entertained when developing treatment strategies for thalamopeduncular tumors of childhood.

It is the sine qua non in the art of aesthetic and reconstructive surgery. http://ift.tt/2sByE5x

Skin and Composite Grafting Techniques in Facial Reconstruction for Skin Cancer

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 12 ώρες
Skin and composite grafting provide effective resurfacing and reconstruction for cutaneous defects after excision of the malignancy. The goal is to restore a natural appearance and function while preventing distortion of the eyelid, nose, or lips. With careful planning and attention to aesthetic subunits, the surgeon can camouflage incisions and avoid blunting aesthetically sensitive sulci. The surgical plan is also informed by the pathology, as basal or squamous cell carcinomas removed by Mohs micrographic excision have different prognostic and logistical considerations from mela...περισσότερα »

Defect of the Eyelids

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 12 ώρες
Eyelid defects disrupt the complex natural form and function of the eyelids and present a surgical challenge. Detailed knowledge of eyelid anatomy is essential in evaluating a defect and composing a reconstructive plan. Numerous reconstructive techniques have been described, including primary closure, grafting, and a variety of local flaps. This article describes an updated reconstructive ladder for eyelid defects that can be used in various permutations to solve most eyelid defects. http://ift.tt/2sBuCuc

Flap Basics III

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 12 ώρες
Paramedian forehead and melolabial flaps are the most common examples of interpolated flaps used by facial plastic surgeons and are excellent options for reconstruction of the midface after Mohs surgery. They provide superior tissue match in terms of thickness, texture, and color, while leaving minimal defects at the tissue donor sites. The main advantage of interpolated flaps is the robust blood supply, which can be either axial of randomly based, and the maintenance of the integrity of facial landmarks. The main disadvantage is the frequent need for a multistage procedure, which...περισσότερα »

Flap Basics II

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 12 ώρες
A mastery of advancement flap design, selection, and execution greatly aids the surgeon in solving reconstructive dilemmas. Advancement flaps involve carefully planned incisions to most efficiently close a primary defect in a linear vector. Advancement flaps are subcategorized as unipedicle, bipedicle, V-to-Y, and Y-to-V flaps, each with their own advantages and disadvantages. When selecting and designing an advancement flap, the surgeon must account for primary and secondary movement to prevent distortion of important facial structural units and boundaries. http://ift.tt/2t6g2yl

Repair of Auricular Defects

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 12 ώρες
Repairing defects of the auricle requires an appreciation of the underlying 3-dimensional framework, the flexible properties of the cartilages, and the healing contractile tendencies of the surrounding soft tissue. In the analysis of auricular defects and planning of their reconstruction, it is helpful to divide the auricle into subunits for which different techniques may offer better functional and aesthetic outcomes. This article reviews many of the reconstructive options for defects of the various auricular subunits. http://ift.tt/2t6f3OD

Reconstruction of defects of the lips after Mohs micrographic surgery should encompass functional and aesthetic concerns. The lower lip and chin compose two-thirds of the lower portion of the face. The focus of this article is local tissue transfer for primarily cutaneous defects after Mohs surgery. Various flaps exist for repair. For small defects, elliptical excision with primary closure is a viable option. During reconstruction of the lip, all of the involved layers need to be addressed, including mucosa, muscle, and the vermillion or cutaneous lip. It is especially important to... περισσότερα »

Successful reconstruction of the cheek following excision for cutaneous malignancy requires careful consideration of defect location, size, and depth in relation to the anatomic properties of the affected cheek unit. Various reconstructive options are available to the surgeon, ranging from simple excisions to complex cervicofacial advancements to meet the needs for functional and aesthetically pleasing reconstructive outcomes. The surgeon must prevent distortion of mobile structures, such as the eyelid, nose, and lips; respect aesthetic subunits; and avoid blunting natural creases...περισσότερα »

Loss of Tyrosine Kinase 2 Does Not Affect the Severity of Jak2V617F-induced Murine Myeloproliferative Neoplasm

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 22 ώρες
Background/Aim: In myeloproliferative neoplasms (MPN), Janus kinase 2 (JAK2) is activated by mutations including JAK2V617F (JAK2VF). It is unclear whether JAK kinases [i.e. JAK1, JAK2, JAK3, or tyrosine kinase 2 (TYK2)] other than JAK2 have cooperative actions such as enhancement or suppression of JAK2. If other kinases enhance activation, therapies that co-target them could have a therapeutic efficacy. We examined the role of TYK2 in Jak2VF-induced murine MPN. Materials and Methods: We crossed Jak2VF transgenic mice and Tyk2-knockout (Tyk2KO) mice to generate Jak2VF/Tyk2KO mice. ... περισσότερα »

Desmoid Tumors in Familial Adenomatous Polyposis

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 22 ώρες
Familial adenomatous polyposis (FAP) is a cancer syndrome caused by a germline mutation in the adenomatous polyposis coli (APC) gene. It is characterized by the presence of hundreds of colonic polyps, which have a high tendency to undergo malignant transformation. Among associated lesions in FAP, desmoid tumors represent a common possible life-threatening condition that requires special attention. They are rare tumors occurring with a particularly high incidence in FAP, especially after surgery. In agreement with Knudson's 'two-hit' theory, the inactivation of the residual APC gen...περισσότερα »

Serum Heparin-binding Epidermal Growth Factor-like Growth Factor (HB-EGF) as a Biomarker for Primary Ovarian Cancer

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 22 ώρες
Ovarian cancer is the most lethal malignancy among gynaecological cancers. Although many anticancer agents have been developed for the treatment of ovarian cancer, it continues to have an extremely poor prognosis. Heparin-binding epidermal growth factor-like grown factor (HB-EGF) has been reported to be a rational therapeutic target for ovarian cancer. Here, we evaluated the clinical significance of serum HB-EGF by examining the association between prognosis and serum HB-EGF levels in patients with primary ovarian cancer. We found that high serum HB-EGF concentrations were signifi... περισσότερα »

Application of Cancer Cell Reprogramming Technology to Human Cancer Research

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 22 ώρες
The cancer stem cell (CSC) hypothesis is an evolving concept of oncogenesis that has recently gained wide acceptance. By definition, CSCs exhibit continuous proliferation and self-renewal, and they have been proposed to play significant roles in oncogenesis, tumor growth, metastasis, chemoresistance, and cancer recurrence. The reprogramming of cancer cells using induced pluripotent stem cell (iPSC) technology is a potential strategy for the identification of CSC-related oncogenes and tumor-suppressor genes. This technology has some advantages for studying the interactions between ... περισσότερα »

Patient-derived Xenografts from Colorectal Carcinoma: A Temporal and Hierarchical Study of Murine Stromal Cell Replacement

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 22 ώρες
Background/Aim: Patient-derived xenografting (PDX) of human colorectal cancer (CRC) is the preferred experimental model to study tumor response to therapeutic agents. Gradually, human stromal cells are replaced by mouse stromal cells; however, the exact timing of the replacement of human with murine stromal cells in human CRC xenograft has not been fully elucidated. We hypothesize that orthologous murine transcripts functionally substitutes for the loss due to replacement of human stromal genes.

Efficacy of Combination Therapy with MET and VEGF Inhibitors for MET-overexpressing Glioblastoma

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 22 ώρες
Background: Glioblastoma multiforme (GBM) is a malignant brain tumor with an extremely poor prognosis. GBM tissues frequently express mesenchymal–epithelial transition factor (MET), which induces cell division, growth and migration. In addition, angiogenesis is a significant feature of GBM, attributable to the overexpression of vascular endothelial growth factor (VEGF). Although the VEGF inhibitor bevacizumab was recently highlighted as the second-line drug for GBM treatment, GBMs often recur even with bevacizumab therapy. Based on these findings, we hypothesized that inhibition o... περισσότερα »
