Submandibular hydatid cyst fistulized into the oral cavity.

Unlabelled: Hydatid cysts of the head and neck are rare, even in regions where echinococcal infestation is endemic. Although complications, like cyst rupture and infection, may occur, an external fistula is extremely rare. This study examined a case of hydatid cyst that had fistulized in the right submandibular region of the oral cavity, which eroded the mandible.

Nitric oxide, lipid peroxidation and antioxidant defence system in patients with active or inactive Behçet's disease.

Background: One of the prominent features of Behçet's disease (BD) is vasculitis and thrombosis as a result of endothelial dysfunction. Nitric oxide (NO) is responsible for endothelial vasorelaxation and inhibition of platelet adhesion.

Objectives: To assess serum total NO, erythrocyte superoxide dismutase (SOD), whole blood glutathione peroxidase (GSH-Px), plasma total antioxidant status (TAS) and plasma malondialdehyde (MDA) in patients with BD and to correlate their levels with disease activity.

General anesthesia versus epidural and general anesthesia in radical cystectomy.

Introduction: The aim of this study is to compare two different anesthetic techniques in radical cystectomy with regard to blood loss, transfusional requirements, intraoperative complications and the quality of analgesia.

Materials And Methods: 50 patients scheduled for radical cystectomy were randomized to two groups: group GA - general anesthesia, n = 25 and group CEGA - combined epidural and general anesthesia. The patients were monitored and hemodynamic changes, intraoperative bleeding, transfusional requirements, quality of analgesia and postoperative complications were evaluated.

The effect of transdermal fentanyl treatment on serum cortisol concentrations in patients with non-cancer pain.

We treated 50 patients with chronic nonmalignant pain using transdermal fentanyl (TDF) 25 microg/hr and concurrently measured pain using a visual analog scale (VAS) and serum cortisol concentration. We determined these outcomes at baseline and on days 30, 60, and 90 of the therapy. The patients also were asked to document any adverse effects.

Evaluation of adding preoperative or postoperative rectal paracetamol to caudal bupivacaine for postoperative analgesia in children.

Background: Our aim was to investigate whether effects of caudal analgesia could be extended by preoperative or postoperative rectal paracetamol administration in children undergoing surgical repair of hypospadias.

Methods: The group consisted of 60 ASA I boys, aged 3-12 years, who were operated for surgical repair of hypospadias. The patients were randomized into three groups: patients in group I received rectal paracetamol (20-25 mg x kg(-1)) just before the operation.

Lipid peroxidation and antioxidant defence system in patients with active or inactive Behçet's disease.

To evaluate plasma lipid peroxidation and enzymatic and non-enzymatic antioxidant systems in patients with Behçet's disease, plasma malondialdehyde levels and total antioxidant status, erythrocyte superoxide dismutase and whole blood glutathione peroxidase activities were studied in 15 patients with active disease and in 30 with inactive disease, and compared with 20 age-matched healthy control subjects. Plasma malondialdehyde levels were significantly higher in patients with active Behçet's disease than in patients with inactive disease, who had significantly higher levels than control subjects. The plasma total antioxidant status of both groups of patients was significantly lower than that of controls.

Evaluation of leukocyte arylsulfatase-A activity in patients with breast cancer and benign breast disease.

This study was planned to evaluate the feasibility of using the assay of leukocyte arylsulfatase-A (AS-A) activity as a non-invasive diagnostic tool in patients with benign and malignant breast disease. The leukocyte AS-A activity of a total of 81 women was analyzed, including 28 healthy women, 29 women with benign breast disease (BBD) and 24 patients with primary breast cancer (BC). The mean leukocyte AS-A activity in patients with BBD was slightly higher (14.
