Importance: The classic management of burn scars and other injuries to the skin has largely relied on soft-tissue transfer to resurface damaged tissue with local tissue transfer or skin graft placement. In situ generation of electrochemical reactions using needle electrodes and an application of current may be a new approach to treat scars and skin. Objective: To examine the changes in optical, mechanical, and acoustic impedance properties in porcine skin after electrochemical therapy...

Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) has an effective role in both diagnosis and management of patients with lung cancer. There are many reasons could cause false positivity on PET/CT.A 60-year-old man was admitted a mass on thorax CT and diagnosed as squamous cell carcinoma. Lobectomy with lymph node dissection was performed after evaluation of distant metastases. There were pathological lymph nodes detected on PET/CT at six month following period. Endobronchial ultrasonography guided transbronchial needle aspiration was performed for differantial diagnosis...

A 2 year old, spayed female African serval was evaluated for a history of abdominal distention. Physical examination findings were consistent with cranial abdominal masses and anemia. Abdominal imaging revealed soft tissue opacity masses in the cranial abdomen and hypoechoic cysts arising from the liver parenchyma. Conservative management failed to improve clinical signs, and a midline exploratory laparotomy was performed. Three large hemorrhagic cysts were visualized occupying a significant amount of the liver parenchyma...

While performing a simple task of following: a suture while closing a surgical wound in a simulated environment, we hypothesized that negative reinforcement results in increased procedural errors, longer operating time and poorer trainee satisfaction. We aimed to measure the effect on participant performance and the perception of the instructor, following positive or negative supervisor feedback during the task. A blinded randomized study was conducted assessing positive and negative supervisor feedback styles on participant performance in a simulated operation room...

OBJECTIVE: To investigate the anti-slip strength of closing systems employing sutures terminated with a Hem-o-Lok®/Lapra-Ty® clip combination to determine which sutures perform best for this application. Partial nephrectomy (PN) is the reference standard for treatment of small renal masses. The main disadvantage of PN is the risk of technical complications, including renorrhaphy site bleeding and urine leak. MATERIALS AND METHODS: A materials testing system produced a constant velocity pull on the free end of an anchored suture...

INTRODUCTION: We used cone-beam computed tomography to evaluate the maturation stages of the midpalatal sutures in children aged 11 to 15 years old. Maxillary expansion is successful for most patients in this age group, so we sought to identify the status of suture maturation in these subjects to use as a comparison for the prognosis of rapid maxillary expansion in older patients. METHODS: Tomographic images in axial sections of the midpalatal sutures from 84 children (40 boys, 44 girls; ages, 11-15 years) were classified using a scale denoting the maturation stage of the midpalatal suture (A, B, C, D, and E)...

Ranulas pose a challenging situation, both clinically and surgically, because of their location on the floor of the mouth, an area that exhibits tightly-netted vital structures. Several treatments have been proposed, including excision with or without removal of the sublingual gland, marsupialization with or without cauterization of the roof of the lesion, drainage of the lesion, and micro-marsupialization. It has been suggested that a modified micro-marsupialization technique can establish drainage of saliva and formation of new permanent epithelized tracts along the path of sutures, thereby reducing the recurrence...

BACKGROUND: Mammaplasty surgery has been modified in the past few years, as plastic surgeons worked to improve and maintain the breast shape and especially the "bottoming out" of the gland. The classic Pitanguy's technique has been shown to be an anatomically safe technique in the management of the breast. However, as first described, cannot be applied in gigantomastia or in severe breast ptosis cases or in cases of dense breast parenchyma or for a long-lasting breast lift result. Using 2 different modifications, the Pitanguy technique can be applied for breasts of all sizes and for all cases of breast ptosis...

AIM: The aim of our study was to describe and assess a new method of mesh fixation using clips in Laparoscopic Ventral Mesh Rectopexy (VMR). This technique avoids knots while suturing in pelvis and saves time. METHOD: A systematic search of the literature (PUBMED, EMBASE) was done to find out alternate ways to fix the mesh over the anterior surface of rectum. This technique has not been used before. We performed five operations using this technique. Indication for surgery was full thickness rectal prolapse in all of them...

BACKGROUND: There is a well known relationship between hypoperfusion and postoperative complications like anastomotic leak. No studies have been done addressing this relationship in the context of abdominal trauma surgery. Central venous oxygen saturation is an important hypoperfusion marker of potential use in abdominal trauma surgery for identifying the risk of anastomotic leak development. The purpose of this study was to identify the relationship between low values of central venous oxygen saturation and anastomotic leak of gastrointestinal sutures in the postoperative period in abdominal trauma surgery...

Advances in molecular biology and nanomedicine based therapies hold promise to obviate the need of multiple surgical interventions (associated with current management) in craniosynostosis by preventing bone re-ossification. One such adjunctive therapy involves application of glypicans 1 and 3 (GPC1 and GPC3) that are BMP inhibitors implicated in downregulating the BMP2 activity in prematurely fusing sutures. Electrochemically anodized Titania nanotube (TNT) arrays have been recognized as a promising localized, long-term drug delivery platform for bone-related therapies...

PURPOSE: Anastomotic or "stitch hole" bleeding is common during vascular surgery with synthetic material such as Dacron or polytetrafluoroethylene (PTFE). Hemostatic adjuncts such as fibrin sealant (FS) may reduce blood loss and operating time in such circumstances. We evaluated the safety and the hemostatic effectiveness of a ready-to-use human plasma-derived FS in vascular surgery. METHODS: Patients with mild / moderate suture line bleeding during elective, open, vascular surgery using synthetic grafts or patches were studied...

Conventional surgical techniques to seal and repair defects in highly stressed elastic tissues are insufficient. Therefore, this study aimed to engineer an inexpensive, highly adhesive, biocompatible, and biodegradable sealant based on a modified and naturally derived biopolymer, gelatin methacryloyl (GelMA). We tuned the degree of gelatin modification, prepolymer concentration, photoinitiator concentration, and crosslinking conditions to optimize the physical properties and adhesion of the photocrosslinked GelMA sealants...
