Öğe A dilemma: Prophylaxis for pulmonary embolism after surgical or invasive interventions for hemodialysis(2006) Alat I.; Türker G.; Akpinar M.B.; Taşkapan H.; Kekilli E.; E?ri M.; Aydin Ö.M.Aim. This study was designed to investigate if it needs to do prophylaxis for pulmonary embolism in the patients treated with different kinds of dialysis or not, and if it is, to find a proper method for prophylaxis. Methods. Ten numbers of patients with central venous catheters (CVC group), 13 numbers of patients with arteriovenous fistula (AVF group) were enrolled in this study. Eleven patients treated with peritoneal dialysis (PD group) were utilized as a control group. Clinical and laboratory examinations to exclude pulmonary embolism were carried out in both AVF and PD groups at the onset and after three months. Same examinations were performed in CVC group at the onset and after 3 weeks (mean: 21 days). Examinations to exclude pulmonary embolism consist of medical history, clinical examinations, d-dimer measures, chest x-ray, respiratory function tests, blood gas analyses, ventilation-perfusion scintigraphies. Results. Neither clinical nor laboratory findings in any stages reflected any suspicion for pulmonary embolism. None of the patients in any groups was admitted with pulmonary embolism in any period of follow-up. There was not any statistically difference between the outcomes of all first examinations and of all second ones (P>0.005). Neither obvious nor subclinical pulmonary embolism was detected in any case. None of the patients had deep venous thrombosis in any stage of follow-up. Conclusion. Conventional techniques of haemodialysis do not lead to pulmonary embolism unless deep venous thrombosis due to any intervention occurs in the patients. Thus, prophylactic anticoagulant usage to prevent pulmonary embolism is not necessary in haemodialysis patients. To shorten the length of stay of central venous catheters is the most important factors for pulmonary embolism prophylaxis in haemodialysis patients.Öğe Takayasu and giant cell (temporal) arteritis: The concealed realities(2004) Alat I.; Bahçeci F.; Taşkapan H.; Saraç K.[No abstract available]Öğe Trace element status (Se, Zn, Cu) in heart failure(2006) Koşar F.; Şahin I.; Taşkapan Ç.; Küçükbay Z.; Güllü H.; Taşkapan H.; Çehreli Ş.Objective: It has been speculated that trace elements may play a role in the pathogenesis of heart failure. In the present study, we aimed to assess serum concentrations of selenium (Se), zinc (Zn) and copper (Cu) in patients with heart failure (HF) and to compare idiopathic dilated cardiomyopathy (IDCM) and ischemic cardiomyopathy (ICM) patients with healthy controls. Methods: This study population included 54 HF patients (26 IDCM patients and 28 ICM patients) and 30 healthy subjects. Serum levels of selenium, zinc, and copper were assessed by atomic absorption spectrophotometry method. Results: Serum concentrations of Se and Zn in HF patients were significantly lower than in healthy controls (p=0.000 and p<0.01, respectively). However, serum Cu concentrations in these patients were significantly higher than in controls (p=0.000). There were no significant difference in the trace elements status between IDCM and ICM patients (p>0.05 for all parameters). Relationships of the serum trace element concentrations studied with echocardiographic and hemodynamic parameters were not statistically significant. Conclusion: Our study showed that heart failure is associated with lower Se and Zn concentrations, and higher Cu concentration, and serum Se, Zn and Cu element profiles were similar in IDCM and ICM.
