OBJECTIVE Surgery for brain aneurysms is technically demanding. In recent years, the process to learn the technical skills necessary for these challenging procedures has been affected by a decrease in the number of surgical cases available and progressive restrictions on resident training hours. To overcome these limitations, surgical simulators such as cadaver heads and human placenta models have been developed. However, the effectiveness of these models in improving technical skills is unknown. This study assessed concurrent and predictive validity of brain aneurysm surgery simulation in a human placenta model compared with a "live" human brain cadaveric model...

Normal tissue damage following radiotherapy is still a major problem in cancer treatment. Therefore, the current work aimed at exploring the possible role of systemically injected bone marrow derived mesenchymal stem cells (BM-MSCs) and/or locally injected platelet rich plasma (PRP) in ameliorating the side effects of ionizing radiation on the rat's tongue. Twelve rats served as control group (N) and 48 rats received a single radiation dose of 13 Gy to the head and neck region; then, they were equally divided into 4 experimental groups: irradiated only (C), irradiated + MSCs (S), irradiated + (PRP) (P), and combined group (PS)...

T2 (tumor invades perimuscular connective tissue; no extension beyond serosa or into liver) gallbladder cancer has generally been treated by S4aS5 subsegmentectomy (S4aS5 HR). We investigated the therapeutic effect of full-thickness cholecystectomy (FC) and gallbladder bed resection (GBR), in terms of tumor location and resection margin (distance from the tumor). At our department we employ the following protocol to determine the extent of resection needed to achieve R0 status: (1) A tumor located in the gallbladder fundus (Gf) or body (Gb) and only on the free peritoneal side was classified as P-type, for which full-thickness cholecystectomy and regional lymph node dissection were performed...

Idiopathic carotidynia is a syndrome characterized by pain and tenderness over the carotid artery without an associated structural luminal abnormality. Controversy exists over whether this is a distinct disease entity or merely a symptom attributable to other causes of neck pain, such as carotid dissection or vasculitis. A 50-year-old woman presented with sudden-onset right neck pain. Imaging studies demonstrated transmural inflammation of the proximal internal carotid artery, without evidence of intraluminal pathology...

INTRODUCTION: A gallbladder mucocele is the distention of the gallbladder by an inappropriate accumulation of mucus. Decreased bile flow, decreased gallbladder motility, and altered absorption of water from the gallbladder lumen are predisposing factors to biliary sludge. However, it is more likely to be a small part of a complex disease process involving inflammation of the gallbladder wall and changes to the lining of the gallbladder changing the consistency of its secretions. We would like to present a case of mucocele gallbladder operated successfully by laparoscopic cholecystectomy...

BACKGROUND: Post-operative hypocalcaemia is the most common complication after total thyroidectomy, with a reported incidence of transient hypocalcaemia up to 50% and permanent hypocalcaemia 1.5-4%. The impact of incidental parathyroidectomy (IPE) on post-operative hypocalcaemia remains controversial. This study evaluated the risk factors for IPE following total thyroidectomy and compared post-operative calcium levels serially between patients with and without IPE. METHODS: A retrospective analysis of patients undergoing total thyroidectomy from January 2009 to October 2016 at Western Health was conducted...

Cervical chylomas are rare pseudocystic collections that lack an epithelial lining and arise from the thoracic duct or its tributaries; although they typically develop after neck surgery or trauma, they can arise from unknown causes. Treatment options include not only conservative therapy, such as dietary modification, repeated aspirations, and sclerotherapy, but also include surgical excision. We describe a case of a chyloma in a 64-year-old Japanese woman with squamous cell carcinoma of the gingiva. The chyloma developed following left segmental mandibulectomy with radical neck dissection and reconstruction, using a titanium plate and a pectoralis major myocutaneous flap...
