BackgroundStatus epilepticus (SE) is a neurological emergency which can be life‐threatening. Several medical regimens are used in order to control it. In this study, we intended to evaluate the clinical efficacy and tolerability of sodium valproate and intravenous phenytoin (IV PHT) in the control of SE.MethodsOne hundred and ten consecutive patients suffering from benzodiazepine refractory SE who were referred to the emergency ward from March 2014 to March 2015 were randomly divided into two groups. The first group received intravenous sodium valproate, 30 mg/kg as loading dose and then 4–8 mg/kg every 8 hr as maintenance regimen. The second group received IV PHT 20 mg/kg as loading dose and then 1.5 mg/kg for 8 hr as maintenance therapy. All patients were monitored for vital signs every 2 hr up to 12 hr. The patients were also followed up for 7 days regarding drug response and adverse effects.ResultsThe administration of sodium valproate and phenytoin respectively resulted in seizure control in 43 (78.18%) and 39 (70.90%) of the patients within 7 days of drug administration (p = .428). Seven‐day mortality rate was similar in both groups (12.73% vs. 12.73%; p = .612). There was no significant difference in adverse effects between two groups.ConclusionSodium valproate is preferred to IV PHT for treatment and control of SE due to its higher tolerability and lower hemodynamic instability.

Renal cell carcinoma (RCC) comprises 2%-3% of all visceral and 80%-85% of all adult kidney malignancies. Nephrectomy is the treatment of choice for renal tumors. The accurate pathological evaluation of nonneoplastic renal parenchyma in nephrectomy specimens is important for subsequent management. Eighty-two patients with RCC who underwent surgery at Imam Khomeini Hospital, Urmia, Iran, from April 2006 to February 2015 were studied. Paraffin blocks of the hospital archives were stained by hematoxylin and eosin (H and E) and periodic acid-Schiff staining. Microscopic examination was performed on nontumoral portions that were in the farthest possible distance from the tumor. Out of total 82 cases, 24 (29.3%) had normal renal parenchyma and 58 (70.7%) had pathological changes in renal parenchyma. The most frequent pathological findings were vascular sclerosis with parenchymal scarring and pyelonephritis. Other findings include focal and diffuse mesangial hypercellularity, eight; focal segmental glome-rulonephritis, five; membranoproliferative glomerulonephritis, three; and membranous glome-rulonephritis, two. Parenchymal scarring and vascular change included 36% of clear cell type, 41% of papillary type, and 53.8% of chromophobe type. Although there is not any statistical relation between the gender of patients and pathological findings, there was an obvious correlation between age and pathological findings. Before the age of 55 years, vascular sclerosis with parenchymal scarring and glomerular diseases and then chronic pyelonephritis are more prevalent.Evaluation of pathological changes in nonneo-plastic renal parenchyma is an essential step in recognizing patients at risk of accelerated functional failure of the single remaining kidney, particularly in patients with a background of chronic vascular injury associated with diabetes or hypertension.
