Öğe A case of rhabdomyolysis accompanying acute renal failure secondary to weight lifting [2](Dustri-Verlag Dr. Karl Feistle, 2003) Baysal O.; Taskapan H.; Taskapan C.; Kaya E.; Sahin I.; Kirimlioglu H.; Karakas N.[No abstract available]Öğe CRP and depression in patients on chronic dialysis [5](Dustri-Verlag Dr. Karl Feistle, 2003) Taskapan H.; Ates F.; Kaya B.; Kaya M.; Emul M.; Taskapan Ç.; Sahin I.[No abstract available]Öğe Development of dermatomyositis in a patient with primary myelofibrosis(Maney Publishing, 2001) Taskapan H.; Gürsoy S.; Cetin M.; Oymak O.; Özbakir Ö.It is known that immunologic mechanisms play an important role in the disease process of some patients with idiopathic myelofibrosis. Patients with idiopathic myelofibrosis have an increased incidence of autoantibodies and circulating immune complexes. Dermatomyositis is a disorder of unknown cause, but immune-mediated muscle damage is believed to be important as a pathogenic mechanism. We have a patient who had idiopathic myelofibrosis and developed dermatomyositis during the disease course, a previously unreported combination. Increasing clinicians' awareness of both myelofibrosis and dermatomyositis may provide further insight into a possible relationship of the two conditions.Öğe Interdialytic weight gain and pulmonary membrane diffusing capacity in patients on hemodialysis(Springer Netherlands, 2004) Taskapan H.; Ulu R.; Gullu H.; Taskapan M.C.; Yıldırım Z.; Kosar F.; Sahin I.Background: Measurement of pulmonary diffusion capacity for carbon monoxide (DLCO) may be useful for assessing disease affecting the alveolar-capillary bed or the pulmonary vasculature. It was reported that hemodialysis (HD) therapy causes DLCO reduction via decrease of pulmonary capillary blood volume components. The aim of the study was to evaluate the effect of interdialytic weight gain on pulmonary function and especially DLCO. We further determined whether intravascular volume status, assessed by inferior vena cava diameter (IVCD) contributes to DLCO in patients on HD. Methods: Routine pulmonary function testing including forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV1/FVC, forced mid-expiratory flow rate (FEF 25-75 ), DLCO IVCD index and other echocardiographic parameters were evaluated in 20 patients (mean age 48.6 ± 18.3 years, mean dialysis duration 17.4 ± 19.2 months) on chronic HD, 1 hour after HD and after an interdialytic period (1 hour before HD therapy). Single-breath DLCO measurements were corrected for hemoglobin concentration (cDLCO). Results: Routine pulmonary function tests (spirometry) showed no significant changes in FEV1, FVC and FEF 25-75 whereas a statistically significant fall in FEV/FVC was found. At the end of the interdialytic period a statistically significant increase in weight, IVCD index, left ventriculer diastolic diameter (LVDD), and diastolic blood pressure (DBP) were observed (P < 0.05). Using the single-breath DLCO, we found unchanged cDLCO at the end of the interdialytic period. There was no correlation of cDLCO with increases in weight, DBP, IVCD index, LVDD (P > 0.05). Conclusion: The accumulation of body water between dialyses has no significant influence on DLCO. © 2004 Kluwer Academic Publishers.Öğe Severe vitamind D deficiency in chronic renal failure patients on peritoneal dialysis(Dustri-Verlag Dr. Karl Feistle, 2006) Taskapan H.; Ersoy F.F.; Passadakis P.S.; Tam P.; Memmos D.E.; Katopodis K.P.; Ozener C.The aim of this study was to evaluate the prevalence of vitamin D deficiency in chronic renal failure (CRF) patients on peritoneal dialysis (PD) and to correlate the findings with various demographic and renal osteodystrophy markers. Method: This cross-sectional, multicenter study was carried out in 273 PD patients with a mean age of 61.7 ± 10.9 years and mean duration of PD 3.3 ± 2.2 years. It included 123 female and 150 male patients from 20 centers in Greece and Turkey, countries that are on the same latitude, namely, 36 - 42° north. We measured 25(OH)D3 and 1.25(OH)2D3 levels and some other clinical and laboratory indices of bone mineral metabolism. Results: Of these 273 patients 92% (251 patients) had vitamin D deficiency i.e. serum 25(OH)D3 levels less than 15 ng/ml, 119 (43.6%) had severe vitamin D deficiency i.e. serum 25(OH)D3 levels, less than 5 ng/ml, 132 (48.4%) had moderate vitamin D deficiency i.e. serum 25(OH)D3 levels, 5 - 15 ng/ml, 12 (4.4%) vitamin D insufficiency i.e. serum 25(OH)D3 levels 15 - 30 ng/ml and only 10 (3.6%) had adequate vitamin D stores. We found no correlation between 25(OH)D3 levels and PTH, serum albumin, bone alkaline phosphatase, P, and Ca × P. In multiple regression analyses, the independent predictors of 25(OH)D3 were age, presence of diabetes (DM-CRF), levels of serum calcium and serum 1.25(OH)2D3. Conclusion: We found a high prevalence (92%) of vitamin D deficiency in these 273 PD patients, nearly one half of whom had severe vitamin D deficiency. Vitamin D deficiency is more common in DM-CRF patients than in non-DM-CRF patients. Our findings suggest that these patients should be considered for vitamin D supplementation. © 2006 Dustri-Verlag Dr. K.

The assessment of such involvement by physical examination alone appears to be inadequate and insensitive. We examined the usefulness of ultrasound (US) examination of the catheter tract in delineating catheter related infections, and their relationship to each other and to peritonitis. Patients were examined during clinically defined states of exit-site infection (ESI), clinically defined tunnel infection (TI), peritonitis and in the normal condition. US examinations of the catheter tunnel were performed in 44 CAPD patients. A total of 47 US examinations (examination was repeated in three patients) were performed, divided among 13 episodes of peritonitis, four ESI, and 30 controls. In 12 of 47 US examinations, US-defined TI was demonstrated as a sonolucent pericatheteric fluid collection. These 12 positive US were distributed among seven patients with peritonitis, three with exit-site infections and two control patients. We conclude that peritonitis and ESIs are frequently accompanied by involvement of the catheter tract. It seems that both the internal and external cuffs do not constitute an effective barrier against the spread of infection. © Springer 2005.
