While primary arteriovenous fistula patency was shortened in chronic renal insufficiency patients with diabetes mellitus, presence of malignancy, and previous catheter insertion, patency was longer in patients with heparin used for hemodialysis and hemodialysis count per week (> or =3).

We believe that TTFM seems to be a crucial tool for deciding if a graft is well-functioning or not, and it allows for improvement of graft failure during operation. Our results suggest that detection of graft dysfunction intraoperatively by TTFM improves the surgical outcome.

This study was designed to determine the activities of superoxide dismutase and glutathione peroxidase and some of the lipid peroxidation indices (malondialdehyde and total sulfhydryl groups) in eutopic and ectopic endometria of patients with endometriosis. Ectopic endometrial tissues (ovarian cysts; n = 22) were obtained laparoscopically during the preovulatory period. Statistical analyses were made using the Wilcoxon signed-rank test. The levels of malondialdehyde and total sulfhydryl groups were similar in the eutopic and ectopic endometria, whereas the superoxide dismutase activity was found to be significantly higher in the latter (1,893 ± 780 vs. 3,512 ± 1,502 U/g protein; p = 0.002). Although the glutathione peroxidase activity was slightly lower in the ectopic than in the eutopic tissues, the difference was not found to be statistically significant. The malondialdehyde levels were positively correlated with the plasma 17β-estradiol concentrations in the ectopic endometria (r = 0.683, p = 0.001). No such correlation was seen in the eutopic tissue. It is suggested that various factors, such as cytokines released by activated macrophages in the peritoneal fluid and 17β-estradiol itself synthesized by the ovaries, may locally affect the oxidant status of ectopic endometria.

Objective: To assess the effectiveness of subxiphoid pericardiostomy in the treatment and diagnosis of pericardial effusions. Methods: 368 patients who underwent subxiphoid pericardiostomy and tube drainage for cardiac tamponade, moderate to severe pericardial effusion, or suspicious bacterial aetiology were retrospectively analysed. Biopsies of the pericardium and fluid samples for diagnostic tests were obtained from each patient. Results: The mean age of the patients was 38.4 years, and the male to female ratio was 220:148. The pericardial effusion was classified by echocardiography as severe in 53% of the patients, moderate in 43%, and mild in 4%. The incidence of cardiac tamponade was 25%. Myocardial injury requiring sternotomy occurred as an operative complication in 0.8% of the patients and recurrent effusion necessitating further surgical intervention developed in 10% of patients. Histopathological examination and the polymerase chain reaction of specimens of pericardium and fluid were helpful for establishing a diagnosis in 90% of patients with malignancy and 92% of patients with tuberculous pericarditis. The overall 30 day mortality rate was 0.8%. Patients were followed up for at least one year. Pericardial constriction requiring pericardiectomy developed in 3% of the patients. Conclusions: Pericardial effusions of various causes can be safely, effectively, and quickly managed with subxiphoid pericardiostomy in both adults and children.

Acute phase reactants have been implicated for their involvement as proinflammatory molecules in various inflammatory diseases. However, little is known regarding their role in the allergic airway disease. The aim of the present study was to examine the blood concentrations of three acute-phase proteins, namely C-reactive protein (CRP), serum amyloid A (SAA) and fibrinogen in patients with allergic rhinitis and asthma. Three study groups include: non-smoker allergic rhinitis (n = 50), non-smoker asthma (n = 20), and non-allergic, non-smoker healthy control subjects (n = 20). Patients who have had recent upper or lower respiratory tract infection and trauma, any rheumatological illnesses, malignancy or obesity were excluded. Blood samples were obtained from all the patients and control subjects and were analyzed for serum CRP, SAA and plasma fibrinogen. The mean CRP and fibrinogen values in the rhinitis and asthma groups were not significantly different when compared to the control group. However, the mean SAA levels of both groups were found to be significantly higher than those of the control group (p = 0.002 for rhinitis, p = 0.02 for asthma). There was no significant correlation between the FEV 1 values and the levels of the serum markers. This study demonstrates that acute phase reactant SAA rises in patients with allergic rhinitis and patients with asthma. We therefore suggest that SAA may have a role in the inflammatory airway disease.acute phase proteins; C-reactive protein; Serum amyloid A; fibrinogen; allergic rhinitis; asthma; inflammation

A 23-year-old man had been coughing with hemoptysis, and had received tuberculostatic medication for four months without any benefit. Upon referral, two-dimensional echocardiography showed a cystic mass located in the anterior right-ventricular wall, without any protrusion into the ventricular cavity. CT examination revealed three cysts in the lung fields bilaterally, additionally a multilocular cystic image in the right-ventricular wall was observed. All components of hydatid cysts in the heart and lungs were removed in the same session by median sternotomy. Extracorporeal bypass was used in this operation.

Fetuin-A is synthesized in the liver and is secreted into the bloodstream. Clinical studies suggest involvement of fetuin-A in metabolic disorders such as visceral obesity, insulin resistance, diabetes, and fatty liver. Curcumin is extracted from the rhizome Curcuma longa and has been shown to possess potent antioxidant, anticarcinogenic, anti-inflammatory, and hypoglycemic properties. In this study, we investigated the effect of curcumin treatment on serum fetuin-A levels as well as hepatic lipids and prooxidant-antioxidant status in rats fed a high-fat diet (HFD). Male Sprague-Dawley rats were divided into six groups. Group 1 was fed control diet (10 % of total calories from fat). Groups 2 and 3 were given curcumin (100 and 400 mg/kg bw/day, respectively ) by gavage for 8 weeks and were fed control diet. Group 4 was fed with HFD (60 % of total calories from fat). Groups 5 and 6 received HFD together with the two doses of curcumin, respectively. Curcumin treatment appeared to be effective in reducing liver triglycerides and serum fetuin-A levels. These findings suggest that the reduction of fetuin-A may contribute to the beneficial effects of curcumin in the pathogenesis of obesity.

The cardiac involvement in Behçet's syndrome in sixty-five patients (mean disease duration 5.7 +/- 4.1 SD years) was studied, in comparison with 70 healthy, age- and sex-matched controls. The electrocardiograms, chest radiographs and M-mode, 2-D and Doppler echocardiography were evaluated in a blind protocol. There were no significant differences in the prevalence of cardiac findings between the probands and the controls. It is concluded that cardiac involvement in Behçet's syndrome occurs only sporadically.
