Methods: The files of 1369 patients who had burn trauma were analyzed retrospectively. Forty-five patients with the diagnosis of psychiatric disorder were assessed based on the variables of age, gender, presence of chronic diseases, psychiatric disorders prior to burn trauma, cause of the burn, burn percentage, degree of burn, additional trauma, number of surgeries, duration of hospitalization, extremity amputation, intubation status, psychiatric symptoms, post-trauma psychiatric disorders, and mortality.

HER-2/neu gene codon 655 (Ile/Val) polymorphism in breast carcinoma patients.

Amplification and/or overexpression of HER-2/neu has been reported to be associated with poor prognosis in breast cancer. One single-nucleotide polymorphism at codon 655 indicates a guanine-to-adenine substitution (Ile655Val) in the transmembrane domain-coding region of the HER-2/neu gene reported to be associated with increased risk of breast cancer. However, several studies have shown that this association is controversial.

Comparison of efficacy of Tc-99m HIG and Tc-99m nanocolloid on sentinel lymph node mapping in patients with breast cancer.

Background And Aim: This study compared the effectiveness of Tc-99m human polyclonal immunoglobulin (HIG) and Tc-99m nanocolloid at detecting sentinel lymph nodes (SLNs) with lymphoscintigraphy and an intraoperative gamma-probe (IGP) in patients with early breast cancer.

Methods: The study group consisted of 50 women; 25 patients each were given Tc-99m HIG or Tc-99m nanocolloid for lymphoscintigraphy. Then, intraoperative SLN localization with IGP was performed.

Retroperitoneal fibrosis and obstructive uropathy due to actinomycosis: case report of a treatment approach.

An actinomycotic retroperitoneal infection usually occurs in the presence of an intrauterine device (IUD). It can result in pelvic inflammatory disease and diffuse retroperitoneal fibrosis. A 39-year-old patient was admitted to the emergency unit with left flank pain.

This case-control study assesses laparoscopic cholecystectomy (LC) in patients with end-stage renal disease treated with continuous ambulatory peritoneal dialysis. Eleven patients receiving peritoneal dialysis treatment and 33 patients without end-stage renal disease who had undergone an elective LC were compared. Medical records were reviewed, and laboratory values and outcomes and results were analyzed.

Male breast cancer: thirteen years experience of a single center.

Background: This retrospective study analysed the epidemiological, clinical, and therapeutic profiles of breast cancer in males.

Methods: We report our experience at the Hospital of the University of Baskent, where 20 cases of male breast cancer were observed and treated between 1995-2008.

Results: Median age at presentation was 66,7 +/- 10,9 years.

Endothelial nitric oxide synthase gene intron 4 (VNTR) polymorphism and vascular access graft thrombosis.

Vascular access thrombosis is a leading cause of vascular access failure in hemodialysis patients. Thrombosis is a multifactorial condition and genetic makeup can affect thrombosis risk. We conducted a study to investigate for possible associations between ecNOS gene intron 4 variable-number tandem repeat (VNTR) polymorphism and thrombosis of polytetrafluoroethylene hemodialysis arteriovenous access grafts (AVG) in Turkish patients.

Clinical findings and HER-2/neu gene amplification status of breast carcinoma patients.

The study group was derived from the archival materials of 48 invasive intraductal breast cancer patients who had undergone partial mastectomy/ axillary dissection. All patients included in the study had clinically T1-2N0M0 invasive ductal carcinoma. To detect HER-2/neu status, fluorescent in situ hybridization was performed using a HER-2/neu locus-specific probe.

Effects of alpha tocopherol and verapamil on liver and small bowel following mesenteric ischemia-reperfusion.

Background/aims: We have previously shown that alpha tocopherol is a potent antioxidant which prevents reperfusion injury in a kidney and small bowel autotransplant model. In this study, the effect of systemic alpha tocopherol and verapamil on small bowel and hepatic functions following mesenteric ischemi-reperfusion was evaluated.

Methods: Fourty male Wistar Albino rats (weight, 250-300 g) all subjected to an ischemia-reperfusion experiment were divided into four groups of 10 as follows: Group 1: (SHAM), Group 2, given prophylactic and systemic alpha tocopherol, Group 3: given verapamil and Group 4: given (both verapamil and alpha tocopherol).

The efficacy of 99mTc-HIG for sentinel lymph node mapping in breast cancer patients.

Objective: To evaluate the efficacy of Tc-HIG on SLN identification in patients with early-stage breast cancer.

Materials And Methods: Seventeen women (18 tumours) with early-stage breast cancer were included. On the day of the operation, 111 MBq Tc-HIG was injected around the tumour or biopsy scar in all patients.

Effects of heparin on bacterial translocation and gut epithelial apoptosis after burn injury in the rat: dose-dependent inhibition of the complement cascade.

This study investigated levels of complement inhibition, apoptosis of gut epithelium, and bacterial translocation (BT) associated with different doses of heparin in rats with severe burns. After burn injury, the animals in Groups 1, 2, 3, and 4 received intravenous tail-vein bolus heparin doses of 150, 300, 600, and 1200 U/kg, respectively. Group 5 received no heparin after burn injury.

The impact of transient elevation of intra-abdominal pressure on liver regeneration in the rat.

Transient increased intra-abdominal pressure (IIAP) due to carbon dioxide insufflation is suspected to cause a form of ischemia-reperfusion injury. Considering this, a study was designed to assess the effect of transient IIAP on liver regeneration in a rat model. Six groups of animals (each n = 6) were studied.

Patients And Methods: The records of 13,443 women with breast-related complaints who were examined by the same surgeon between 1 January 1960 and 31 December 2000 were retrospectively assessed. Patients with ND were grouped according to whether they had had a spontaneous or provoked discharge.

Endovascular stent placement in the treatment of upper extremity central venous obstruction in hemodialysis patients.

Objective: To evaluate the efficacy of stent placement for treating upper extremity central venous obstruction in chronic hemodialysis patients.

Methods And Material: Between January 1999 and October 2001, we inserted metallic stents into the upper extremity central veins of 14 patients with shunt dysfunction and/or arm swelling. The indications for stent placement were stenosis or occlusion of the central vein in the upper extremity used for dialysis.

Atypical presentation of chronic pancreatic fistula: a case successfully managed with long-acting somatostatin.

Pancreatic fistula is a potential complication of trauma or inflammation of the pancreatic duct or accessory pancreatic ducts. These fistulous tracts tend to form external to the pancreas; internal cases are rare. Pharmacological inhibition of pancreatic exocrine secretion and conservative approaches such as percutaneous endoscopic interventions are widely used to treat pancreatic fistulae.
