Subdural empyema and unilateral pansinusitis due to a tooth infection

Paranasal sinus infections are very common. Dental infections, tumours and anatomical malformations can cause unilateral sinusitis. Most cases can be treated without complications. However, rare life-threatening intracranial complications can occur. Generally, an intracranial complication progresses rapidly and can cause meningismus, focal neurological disorders, loss of consciousness and seizures

Treatment of acromegaly by endoscopic transsphenoidal surgery : Surgical experience in 214 cases and cure rates according to current consensus criteria - Clinical article

Object. Acromegaly is a disease that has significant morbidity and mortality related to high levels of growth hormone (GH) and insulin-like growth factor-I (IGF-I), and is usually caused by pituitary adenomas. The goal in this study was to investigate the role of endoscopic transsphenoidal surgery and surgical experience in the treatment of GH adenoma cases in relation to surgical results and horm

Comparison of the toxicities of ethylene vinyl alcohol copolymer (EVOH) preparations, dimethyl sulphoxide and N-butyl 2-cyanoacrylate on cerebral parenchyma in an experimental rabbit model

AIM: Ethylene vinyl alcohol copolymer (EVOH), its organic solvent dimethyl sulfoxide (DMSO), and N-Butyl 2-Cyanoacrylate (NBCA) are widely used in neurovascular embolization procedures and yet with potential risk of cytotoxicity. The aim of this study was to evaluate the toxic effect of EVOH-DMSO, its solvent DMSO and NBCA on cerebral parenchyma in a rabbit model. MATERIAL and METHODS: Forty-eight

De novo formation of brain tumors in pediatric population following therapeutic cranial irradiation

Purpose: Tumors of central nervous system (CNS) are accounted as the second most common tumors in childhood (21 % of all cancers) following hematologic malignancies. The patients can suffer more than one cancer in their lifetime, and radiotherapy is claimed for de novo formation of a new tumor in years after treatment of an initial tumor. Methods: We have retrospectively analyzed our database for

The effect of poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) and human mesenchymal stem cell (hMSC) on axonal regeneration in experimental sciatic nerve damage

This study is designed to evaluate the treatment effect of poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) and human mesenchymal stem cells (hMSC) on axonal regeneration in experimental rat sciatic nerve damage, and compare the results of this modality with autologous nerve grafting. In Spraque-Dawley albino rats, 10-mm-long experimental nerve gaps were created. Three groups were constitute

Peripheral nerve

In order to understand peripheral nerve dysfunction, and to follow neuronal regeneration, basic sciences of the peripheral nerve should be understood completely. A surgeon who operates on "nerves" uses this knowledge, especially the organization of the peripheral nerve, in nerve reconstructions. When a nerve has been injured, the goal of surgical repair is generally to reapproximate the ends of th

Complications of endoscopic surgery of the pituitary adenomas : Analysis of 570 patients and review of the literature

Endoscopic transsphenoidal surgery is emerging as a minimally invasive and maximally effective procedure for pituitary adenomas. In this report we analyzed the complications in 624 procedures of endonasal transsphenoidal endoscopic surgery in the treatment of 570 patients with pituitary adenomas. The leading author (MB) operated pituitary adenomas via pure endoscopic endonasal transsphenoidal surg

In vivo application of poly-3-hydroxyoctanoate as peripheral nerve graft

Objective: This study aims to investigate the degree of biocompatibility and neuroregeneration of a polymer tube, poly-3-hydroxyoctanoate (PHO) in nerve gap repair. Methods: Forty Wistar Albino male rats were randomized into two groups: autologous nerve gap repair group and PHO tube repair group. In each group, a 10-mm right sciatic nerve defect was created and reconstructed accordingly. Neurorege

A case of gonadotropinoma with polycysts as remnants of Rathke's cleft

Context. This is a case of gonadotropinoma presented with Rathke's cleft cyst. Objective. We are presenting a case of gonadotropinoma along with Rathke's cleft cyst which is unique case as being male and symptomatic gonadotropin releasing adenoma. Method. A 51 year old man was referred to our institution for evaluation of impotence and loss of libido. His endocrine screening evaluations revealed h

Spontaneous resolution of syringomyelia without Chiari malformation - Case report

A 30-year-old woman presented with a cervical syrinx manifesting as hemihypesthesia. Neuroimaging found no evidence of Chiari malformation or tight cisterna magna. Serial magnetic resonance imaging studies over a 6-year period demonstrated spontaneous and complete resolution of the syrinx accompanied by an asymptomatic clinical course. The natural history of syringomyelia is highly unpredictable.
