Single-stage full-depth scalp reconstruction with Matriderm®: a clinical case report and a brief literature review.

Reconstructing scalp defects after basal cell carcinoma removal in elderly patients is challenging. This case report emphasizes Matriderm® as a successful alternative, addressing limitations of traditional methods. The application of Matriderm® in resource-limited scenarios adds insights to surgical literature, and its' usage addresses challenges in patients, contributing to surgical knowledge.

Gangrenous Cystitis: A Rare Case Report.

Gangrenous cystitis is a rare condition of the urinary bladder with bladder wall ischemia as the main etiopathogenic factor and constitutes a surgical emergency. The risk factors for this condition include diabetes mellitus, prolonged labor, and topical chemotherapy, and the condition must be immediately treated because of its high mortality rate. This report describes a rare case of a patient with gangrenous cystitis who underwent radical surgical treatment; the incidence, etiology, diagnosis, management, and outcomes are also discussed.

Prospective multicenter external validation of postoperative mortality prediction tools in patients undergoing emergency laparotomy.

Background: Accurate preoperative risk assessment in emergency laparotomy (EL) is valuable for informed decision making and rational use of resources. Available risk prediction tools have not been validated adequately across diverse health care settings. Herein, we report a comparative external validation of four widely cited prognostic models.

Anatomical Variations of the Axillary Arch and Implications in Breast Surgery.

Introduction: Langer's axillary arch (AA), the most common anatomical variant in the axillary area of definite clinical significance. This is an updated review of the reported variations in the structure, highlighting its morphological diversity and its potential in complicating axillary lymph node biopsy, lymphadenectomy, or breast reconstruction.

Methods: A review of the literature concerning the AA published between 1812 and 2020 was performed using the PubMed, Scopus, Embase, and Cochrane medical databases.

Double appendixes: A rare case report.

Anomalies of the appendix are rare, and one of the rarest is the double appendixes. Most anomalies of the appendix are observed in adults and are discovered incidentally during surgery that does not primarily involve the appendix. It is usually missed, often with life-threatening consequences.

Α modified temporalis transfer technique for facial paralysis in elderly patients.

Introduction: In patients with chronic facial palsy where the treatment by conservative means or only nerve grafting is no longer an option, reconstruction by dynamic procedures such as pedicled and/or free muscle transfer is required.

Patients And Methods: Five patients with chronic facial palsy were treaded by temporalis muscle transfer to the eye and mouth simultaneously. In four of them, the combined Gillies-McLaughlin technique was used, but for the fifth one, a modified technique was applied.

Acute appendicitis as the first presentation of appendiceal metastasis of gastric cancer-report of a rare case.

Metastatic tumors of the appendix is a rare entity, whereas only limited data involving metastasis arising from gastric cancer has been reported. Herein, the case of gastric adenocarcinoma metastasis presenting as acute appendicitis is reported. A 53-year-old male, with a history of subtotal gastrectomy due to gastric adenocarcinoma 3 years before, was referred to the Emergency Department with symptoms of acute appendicitis.

Biliary tract injuries after lap cholecystectomy-types, surgical intervention and timing.

Bile duct lesions, including leaks and strictures, are immanent complications of open or laparoscopic cholecystectomy (LC). Endoscopic procedures have gained increasing potential as the treatment of choice in the management of postoperative bile duct injuries. Bile duct injury (BDI) is a severe and potentially life-threatening complication of LC.

A neural network-based novelty detector for image sequence analysis.

This paper proposes a new model of "novelty detection" for image sequence analysis using neural networks. This model uses the concept of artificially generated negative data to form closed decision boundaries using a multilayer perceptron. The neural network output is novelty filtered by thresholding the output of multiple networks (one per known class) to which the sample is input and clustered for determining which clusters represent novel classes.
