Menatetrenone (MK-4) inhibits bone resorption and enhances osteoblast-induced mineralization. In this study, we examined whether MK-4 administration had beneficial effects on osteoblast dysfunction and trabecular microstructure as well as on bone volume loss in a rat model of osteopenia. Male Sprague-Dawley rats were neurectomized and administered MK-4 as a daily supplement. On Day 21 after neu...

Chylous ascites is an extremely rare complication of laparoscopic presacral neurectomy (LPSN), and treatment is still controversial. Four patients undergoing LPSN for dysmenorrhoea or chronic pelvic pain were complicated with chylous ascites. Two were successfully treated with bipolar cauterization and one, after the failure of initial treatment by bipolar cauterization, was then effectively ma...

We studied the effects of unilateral sciatic neurectomy (USN) on the development of the femoral shaft in the 30 growing Wistar-derived rats aged 5 weeks. Rats were allocated to three groups. One of these was immediately used for measurements, and the remaining 2 groups underwent USN of internal control. Specimens obtained from each group were divided into 2 subgroups: left femurs of each group ...

One of the constant side-effects of a successful transantral vidian neurectomy, well-known among otolaryngologists, is the interruption of the secreto-motor nerve supply to the lacrimal gland. Since this secreto-motor nerve supply is concentrated in the nerve of the pterygoid canal (vidian nerve) this is only to be expected. This depression of lacrimation appears to be permanent, yet in some 30...

Inguinal hernias are one of the commonest surgical problems in our set up. It is a protrusion of abdominal cavity contents through the inguinal canal. This is a retrospective study done in the Department of Surgery, Nepal Medical College Teaching Hospital (NMCTH) from January 2009 to December 2010. During this period, 120 patients with painless hernia were enrolled in the study. The age range w...

UNLABELLED Impact in vocal quality in partial myectomy and neurectomy endoscopic of thyroarytenoid muscle in patients with adductor spasmodic dysphonia the adductor spasmodic dysphonia is a severe vocal disorder characterized by muscle laryngeal spasms during speech, producing phonatory breaks, forced, strained and strangled voice. Its symptoms come from involuntary and intermittent contraction...

The question of which nerve--the ilioinguinal or the iliohypogastric--most often causes chronic groin pain after hernia repair remains to be answered. We sought to evaluate the effects of prophylactic neurectomies on the incidence of persistent groin pain after Lichtenstein repair. Two hundred forty patients were randomized to 1 of 4 groups: the all-nerve preservation group, the ilioinguinal ne...

Occipital neuralgia is usually defined as paroxysmal stabbing pain in the greater or lesser occipital nerve (GON or LON) distribution. In occipital neuralgia patients, surgical considerations are carefully taken into account if medical management is ineffective. However, identification of the occipital artery by palpation in patients with thick necks or small occipital arteries can be technical...

Unilateral sciatic neurectomy (USN) resulted in cortical osteopenia in tibiae from the sciatic nerve-sectioned limb of growing rats. The bone deficit resulted from decreased periosteal addition; there were no changes in the indexes of bone resorption. The periosteal bone formation rate was reduced in the nerve-sectioned limb within 7 days of sciatic neurectomy, and this decrease persisted for a...
