Background. Insulin resistance was an independent predictor of cardiovascular mortality in uremic patients without diabetes. Rosiglitazone (ROS) improves insulin sensitivity in the liver, muscle, and adipose tissue. We prospectively investigated the effects of ROS on cardiac functions by standard (SDE) and tissue Doppler echocardiography (TDI) in continuous ambulatory peritoneal dialysis (CAPD) patients. Methods. A total of 24 CAPD patients (13 males, 11 females; mean age 42.2 ± 14.8 years) were included. Routine blood samples were examined. Left and right ventricular functions were assessed, and myocardial performance index (MPI) was calculated by SDE and TDI at baseline and after 12-month ROS therapy. Left and right atrial volumes were measured and indexed to body surface area. Results. When compared with baseline, after 12 months of ROS treatment, it was shown that early (E) and late (A) diastolic velocities of atrioventricular valves, E/A ratio, mitral E-wave deceleration time (DT), isovolumetric relaxation time (IVRT), and MPI were similar (p > 0.05). Also, no significant changes were detected in LV dimensions, LV mass index, LVEF, LA volume index, or RA volume index measured by SDE before and after ROS therapy (p > 0.05). Left and right ventricular function parameters measured by TDI including Sm, Em, Am, Em/Am ratio, E/Em ratio, and MPI were similar. Conclusion. It was found that there was no negative effect of long-term ROS therapy on cardiac functions measured by SDE and TDI in CAPD patients. 相似文献

Purpose
To evaluate the outcomes of Ahmed glaucoma valve (AGV) in the management of elevated intraocular pressure (IOP) secondary to steroid use for macular edema in patients with retinitis pigmentosa (RP).Methods
A total of nine eyes of five patients were evaluated retrospectively. Complete success was defined as IOP ≤ 21 mmHg without glaucoma medications, while qualified success was defined as IOP ≤ 21 mmHg with glaucoma medications.Results
Mean age at surgery was 25.0 ± 8.3 years, and mean follow-up time was 38.4 ± 13.2 months. Mean IOP was 41.0 ± 8.3 mmHg preoperatively, 9.4 ± 3.5 mmHg at first week (p = 0.008), 13.1 ± 3.6 mmHg at first month (p = 0.008), 14.8 ± 4.1 mmHg at 6th month (p = 0.008), 11.7 ± 2.6 mmHg at 12th month (p = 0.008), 12.4 ± 2.9 mmHg at 24th month (p = 0.008), 12.6 ± 3.6 mmHg at 36th month (p = 0.043) and 12.8 ± 4.2 mmHg at 48th month (p = 0.068) postoperatively. The mean number of topical anti-glaucomatous medications decreased from 2.8 ± 0.4 preoperatively to 0.4 ± 0.9 postoperatively (p = 0.007). Complete success was obtained in 7 (77%) eyes, and qualified success in 2 (23%) eyes. No failure was detected.Conclusions
AGV implantation can be considered as an alternative and safe option in the management of resistant, elevated IOP secondary to steroid treatment for macular edema in patients with RP.4.

Coronary artery aneurysms are defined as coronary dilatations which exceed the diameter of normal adjacent segments by 1.5 times. Left main coronary artery (LMCA) is the least frequently involved artery with a prevalence of 0.1%. Majority of coronary artery aneurysms are atherosclerotic in origin. Their size and clinical presentation is variable. A number of complications have been reported to occur during the course of the disease including thrombosis and distal embolization, myocardial ischemia and/or infarction, dissection, vasospasm, calcification, fistulization and very rarely rupture. Large aneurysms of LMCA represent a potentially fatal condition even without concomitant atherosclerotic coronary disease. Because of rarity of coronary artery aneurysms, it is difficult to standardize treatment. In this article, we presented 4 cases of large LMCA aneurysms with various clinical and angiographic features. 相似文献

Cases with cardiac hydatid cyst disease are uncommon, being approximately 0.2-2% of all cases. Most cardiac hydatid cysts are located in the interventricular septum or left ventricular wall. Pericardial location is very rare. We report a 42-year old Turkish man with pericardial hydatid cyst disease who was otherwise asymptomatic, having no cardiac symptomatology. The most appropriate therapeutical option for a hydatid cyst is surgical removal of the cyst mass. However, our patient refused surgical treatment and thus medical treatment with albendazole was initiated. Following the first month of the drug therapy, pericardial effusion disappeared. The cystic nature of the mass disappeared and was solidified at the 6th month of treatment. The patient has been followed-up by us asymptomatically. 相似文献

BACKGROUND: Familial Mediterranean fever (FMF) is an autosomal recessive disease seen primarily in Sephardic Jews, Turks, and Armenians. The disease manifests as recurrent attacks of fever and serositis. The most important complication of FMF is the development of renal failure due to AA type amyloidosis. There has not been extensive experience with renal replacement therapy in FMF amyloidosis. Nevertheless, there may be a concern about the possibility of higher rates of morbidity and mortality in amyloidotic patients maintained on chronic hemodialysis. Moreover, there is not enough experience regarding patients on chronic peritoneal dialysis. As a result, the best treatment modality of end-stage renal disease (ESRD) in these circumstances still remains unclear. This study aimed to compare the effect of hemodialysis and peritoneal dialysis modalities on clinical outcomes in ESRD patients associated with FMF amyloidosis. METHODS: Forty FMF patients with ESRD due to amyloidosis were retrospectively analyzed. All 40 patients were on renal replacement therapy, 20 on hemodialysis (HD), 20 on peritoneal dialysis (PD). Peritoneal solute transport rates, weekly mean creatinine clearance, and daily mean ultrafiltration (UF) of the patients on chronic peritoneal dialysis were evaluated. Weekly dialysis durations, dialysis membrane properties, Kt/V values, interdialytic weight gains, and frequency of hypotension during dialysis were evaluated on hemodialysis patients. All of the patients were examined according to their demographic characteristics, laboratory results, duration time on dialysis, erythropoietin requirements, frequencies of infectious complications requiring hospitalization, and the two renal replacement modalities mentioned above were compared in terms of these parameters. RESULTS: Serum albumin levels of the patients with FMF amyloidosis who were maintained on peritoneal dialysis treatment were lower (2.87 vs 3.45) and the frequency of infections of the same group was higher (4.2 vs 0.5) than the patients with ESRD secondary to other diseases in the CAPD group. CONCLUSIONS: This retrospective analysis showed that peritoneal dialysis may have some disadvantages in amyloidotic patients. Due to the high frequency of hypoalbuminemia and infectious complications seen in this group, peritoneal dialysis is widely accepted as an alternative choice of treatment when hemodialysis is not appropriate. 相似文献

Antioxidant effects of sulfur-containing amino acids 总被引:4,自引:0,他引:4

Sulfur is an essential element for the entire biological kingdom because of its incorporation into amino acids, proteins and other biomolecules. Sulfur atoms are also important in the iron-containing flavoenzymes. Unlike humans, plants can use inorganic sulfur to synthesize sulfur-containing amino acids. Therefore, plants are an important source of sulfur for humans. Sulfur-containing compounds are found in all body cells and are indispensable for life. Some of sulfur-containing antioxidant compounds are, cysteine, methionine, taurine, glutathione, lipoic acid, mercaptopropionylglycine, N-acetylcysteine, and the three major organosulfur compounds of garlic oil, diallylsulfide, diallyldisulfide and diallyltrisulfide. In a comparison of the structure-function relationship among these sulfur-containing antioxidant compounds, dihydrolipoic acid (the reduced form of LA) is the most effective antioxidant. Dihydrolipoic acid contains two sulfhydryl groups and can undergo further oxidation reaction to form lipoic acid. The antioxidative activities of sulfur-containing compounds follow a general trend, the more highly reduced forms are stronger antioxidants and the number of sulfur atoms determine, at least in part, their modulatory activites on the glutathione related antioxidant enzymes. In this article, the antioxidant effects and the antioxidative activities, of sulfur-containing amino acids, are reviewed. In addition, the general antioxidant effects and the structure-function relationship of some sulfur-containing compounds are also reviewed. 相似文献
