Objective-To evaluate effect of chitosan conduit for peripheral nerve regeneration using sciatic nerve transection model in rat DesignExperimental in vivo study. AnimalsSixty healthy male Wistar rats. Procedures-The rats were divided into four experimental groups (n=15) randomly. In sham group the left sciatic nerve was exposed through a gluteal muscle incision and after careful homeostasis the...

OBJECTIVES To evaluate the surgical outcomes of endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone stenting in patients with distal or common canalicular obstructions. METHODS The medical records of 29 patients (31 eyes) from January 2001 to December 2009 who underwent endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone tube inser...

Cerebrospinal fluid (CSF) shunt failure is commonly associated with infection or mechanical obstruction of the shunt system. A 4-year-old male child who had undergone multiple shunt revisions at another hospital for congenital hydrocephalus and later for shunt obstruction, presented with exposed shunt at the supraclavicular region. Shunt revision was performed. The CSF culture showed no growth;...

We introduce a new strategy for fabricating a seamless three-dimensional (3D) helical microreactor utilizing a silicone tube and a paraffin mold. With this method, various shapes and sizes of 3D helical microreactors were fabricated, and a complicated and laborious photolithographic process, or 3D printing, was eliminated. With dramatically enhanced portability at a significantly reduced fabric...

Esophageal foreign bodies (FB) are common in adults and children. These are rarely reported in infants and neonates. A 2-day-old newborn was referred to our hospital with history of accidental intrusion of soft silicone suction catheter into the upper gastrointestinal tract (GIT). X-ray chest and abdomen confirmed the presence of suction tube in esophagus and stomach. The suction catheter was r...

Patients undergoing neoadjuvant therapy for esophageal cancer are at a high risk for malnutrition due to the effects of chemoradiation, dysphagia, and malignancy induced cachexia. Preparation for esophagectomy requires careful assessment of nutritional risk and adequate supplementation as indicated. Supplementation via the enteral route is preferred to the parenteral route but requires feeding ...

AIM Effects of homeopathic treatment with Hypericum perforatum (Hypericum) on peripheral nerve regeneration was studied using a rat sciatic nerve transection model. METHODS Fifty-four male healthy White Wistar rats were divided into three experimental groups (n = 18), randomly: Sham-operation (Sham), control: silicon tube (Sil) and treatment: silicon tube + Hypericum (Sil/Hypericum). In the S...

We compared the effects of FK506 administration on regeneration and reinnervation after sciatic nerve resection and repair with an autologous graft or with a silicone tube leaving a 6-mm gap in the mouse. Functional reinnervation was assessed by noninvasive methods to determine recovery of motor, sensory, and sweating functions in the hindpaw over 4 months after operation. Morphometric analysis...
