Background and Purpose:Status epilepticus (SE) is defined as epileptic seizures of greater than five minutes or more than one seizure within a five minute period without returning to normal consciousness between them. It is a life-threatening condition particularly if treatment is delayed. Previous studies reported age, duration and etiology of SE as primary determinants of mortality.Methods:This prospective cross-sectional study performed on the patients with status epilepticus admitted in Rasoul-e-Akram hospital in Tehran. Patients followed at 30th day after SE to assess their living status.Results:Sixty-five patients, (56.9% was male) with 15 to 88 years of age entered the study. Mean duration of SE was 40 minutes and for hospital stay was 7 days. 84.6% of patients responded to treatment and 11 patients (16.9%) died within 30 days after SE. Mortality rate in patients with refractory SE was 70%. Mean interval between SE and death was 11.9 ± 11.7 days. Age, duration of SE and hospital stay, history of head trauma and neurosurgery were not predictors of mortality. Negative history for epilepsy had significantly higher mortality rate. Anoxic encephalopathy increased the mortality rate and response to treatment decreased it.Conclusions:Short-term mortality rate of SE was comparable with most of the previous reports Since our hospital has equipped emergency department, resuscitation and primary treatment of SE is usually start soon, percentage of anoxic encephalopathy is decreased and lower mortality rate is expected. We conclude that early treatment by decrease chance of anoxic encephalopathy, has significant role in outcome of SE.

Introduction: Hemodialysis (HD) has impact on the cardiovascular system by inducing changes in the characteristics of body fluids such as PH, temperature and electrolyte concentrations. In the previous studies, prolongation of the QT interval and increase of QT dispersion have been reported during HD sessions. These changes were more significant while using solutions with less potassium and higher bicarbonate during dialysis. Objectives: The aim of our study was to investigate the effects of different potassium and bicarbonate concentrations on electrocardiography (ECG) parameters and the electrochemical balance of cell membranes. Patients and Methods: This is a double blind controlled clinical trial with crossover design. This interventional study has been conducted on 36 patients over 18 years who undergoing HD 3 times a week for at least 6 months. Twelve-lead ECG has been obtained before starting and one hour after end of each HD session. The QTc was measured and changes recorded by a cardiologist. Correlations were evaluated by univariate regression analysis. Results: 54.38 years (16 to 77 years), 66.7% were male. No significant increase in QT interval has been seen while dialyzing with 2 meq/l potassium and 24 meq/l bicarbonate, 2 meq/l potassium and 28 meq/l bicarbonate and 3 meq/l potassium and 24 meq/l bicarbonate beside high calcium (2.5 meq/l) dialysate was conducted. Age, gender, serum calcium and serum bicarbonate level before HD session did not influence the mean QT intervals before and after dialysis. Conclusion: Concentration of potassium beside moderate dose of bicarbonate in dialysis bath had not any significant influence on QT intervals after dialysis.

Background: Deep vein thrombosis (DVT) can be an ethnicity related disease and an important health issue for health-care systems. Thus, domestic recognition of risk factors and disease characteristics seem to be inevitable. This study was designed to evaluate the epidemiology, basic characteristics, and risk factors in patients with DVT.Materials and Methods: In this descriptive cross-sectional study, all patients with primary or final diagnosis of DVT, confirmed by Doppler ultrasound in a 5-year period were included. Demographic data and prognosis were extracted from medical files. To evaluate the outcome of the patients after discharge, a phone-call follow-up was performed for all available patients.Results: Three-hundred seventy-one DVT patients were included with 232/139 male to female ratio. The mean age was 55.72±20.01 years with significant difference between genders (p=0.006). Mean weight was 88.97±10.2 kg with no significant difference between genders (p=0.74). The most common affected veins were common femoral vein (257 cases, 69.2%), followed by Popliteal, iliac, axillary, and subclavian veins. No season preference was seen in DVT occurrence. One-year survival of the patients after discharge was 92.6% and two-year survival was 87.7%.Conclusion: By knowing local information about this disease, health-care providers can give accurate warnings and suggestions to prevent the probable thrombosis chances. As Iran lacked information about DVT characteristics, this study can be an epidemiologic guide for health-care systems and an opening path for future studies.
