Evolving of a single centre by means of different transsphenoidal approaches during the survey of methodological advances in pituitary surgery is presented. Ninety-three consecutive patients with pituitary adenomas underwent transphenoidal pituitary operations at Gulhane Military Medical Academy from January 1996 to October 2007. Retrospective chart-based(More)
The aim of this study was to investigate the neuroprotective effects of propofol, thiopental, etomidate, and midazolam as anesthetic drugs in fetal rat brain in the ischemia-reperfusion (IR) model. Pregnant rats of day 19 were randomly allocated into eight groups. Fetal brain ischemia was induced by clamping the utero-ovarian artery bilaterally for 30 min(More)
AIM The aim of this study was to investigate the neuroprotective effect of magnesium sulfate and dexamethasone on oxidative damage in intrauterine ischemia. MATERIAL AND METHODS In this study, 19-day pregnant rats were divided into five groups. Fetal brain ischemia was achieved in the ischemia/ reperfusion (I/R) group by bilaterally closing the(More)
We report an instance of transfusion-induced anti-k so severe that three intrauterine intravascular fetal transfusions were required. The pretransfusion circulating hemoglobin level in the fetus was 60 g/l and hematocrit was 0.19. This, to our knowledge, is the first example of the rare alloantibody, anti-k, producing erythroblastosis so severe that fetal(More)
STUDY DESIGN Retrospective case series. PURPOSE The objectives of this study were to determine and discuss the surgical planning of patients who underwent operations following diagnoses of thoracal and lumbar spinal schwannomas. We also aimed to discuss the application of unilateral hemilaminectomy for the microsurgery of schwannomas. OVERVIEW OF(More)
OBJECTIVE To study the effects of pre-ischemic hyperbaric oxygen (HBO) and post-ischemic aminoguanidine (AG) on the infarct volume in permanent middle cerebral artery occlusion. METHODS This study was approved by the Animal Experiments Ethics Committee of Gulhane Military Medical Academy, Ankara, Turkey and carried out from March 2006 to August 2006. A(More)
To the Editor: We present a case of cerebellar ischemia following a lumbar spinal surgery with prolonged prone position. Acute cerebellar ischemia after lumbar surgery is extremely rare, and its exact cause is not well known [1, 2]. Compression of vertebral arteries as a result of the prone position and unusual neck rotation with prolonged surgery have been(More)
Ventriculoperitoneal (VP) shunt transfers cerebrospinal fluid from the lateral ventricles of the brain to the peritoneum via subcutaneous tubing. VP shunt implantation is the most widely used treatment for the management of hydrocephalus [2]. Although VP shunting reduces the mortality and morbidity of hydrocephalus, there are potential shunt complications(More)
To review relevant data for the management of esophageal perforation after anterior cervical surgery. A case of delayed esophageal perforation after anterior cervical surgery has been presented and the relevant literature between 1958 and 2014 was reviewed. A total of 57 papers regarding esophageal perforation following anterior cervical surgery were found(More)
BACKGROUND Vitamin B12 and alpha lipoic acid (ALA) are known to promote functional and morphological recovery after peripheral nerve injury. OBJECTIVE To compare the regenerative and neuroprotective effects of vitamin B12 and ALA treatment after sciatic nerve injury. METHODS A total of 40 rats were randomly assigned to control (sciatic nerve exposure(More)
