  ABSTRACT: Human T-cell lymphotropic virus 1 (HTLV1) is a lymphotropic virus which can be transmitted through unprotected sexual activity, breast feeding, and blood transfusion. Although most of HTLV1-infected individuals remain asymptomatic carriers, 1% to 5% and 3% to 5% develop adult T-cell leukemia and HTLV1-associated myelopathy/tropical spastic paraparesis, respectively. The aim of this study was to determine the prevalence of HTLV1 infection in hemodialysis patients in Sari and Ghaemshahr. This cross-sectional study was conducted on160 patients using random samples selection, and included 80 men and 80 women (mean age, 59.1 ± 14.7 years). All the samples were screened for HTLV1 antibody by enzyme-linked immunosorbent assay and positive samples were confirmed by Western blot assay. Only 1 patient had a positive anti-HTLV1 enzyme-linked immunosorbent assay test, which was confirmed by Western blot. The overall prevalence of HTLV1 seropositivity was 0.6%. The patient was a 21-year-old woman with a history of multiple blood transfusions. She had a history of unsuccessful kidney transplantation and had been on hemodialysis before transplant, too. This study suggests that HTLV1 infection may not be prevalent in high-risk patients in Mazandaran province, and there is no need for HTLV1 screening of blood samples.

  ABSTRACT: Background: Allergic diseases including asthma, allergic rhinitis (AR) and eczema are common chronic diseases in children. The purpose of this study was to determine the prevalence of asthma, AR and eczema in Sari, Iran. Methods: This study was carried out on all elementary schools selected as a cluster from February 2010 to July 2010 in Sari, North of Iran. A questionnaire was provided according to International Study of Asthma and Allergies in Childhood (ISAAC) protocol. Asthma, AR, eczema and their combinations were recorded. Results: Out of the 1818 cases, 646 (35%) subjects had allergic disorder; 223 (12%) had asthma, 318 (17%) had AR and 105 (6%) had eczema The prevalence of allergic disorder in boys (65%) was higher than the girls (40%) (p<0.05). Conclusion: The results show that around one – third of the elementary school children have allergic disorders. The prevalence in males is higher than the females.

  ABSTRACT: Urinary tract infections (UTI) are one of the most common infections with an increasing resistance to antimicrobial agents. Purpose: Empirical initial antibiotic treatment of UTI must rely on susceptible data from local studies. Materials and Methods: Retrospective analysis of isolated bacteria from children with UTIs was performed at the university hospital during years 2006-2009. The findings were compared with data collected in a similar study carried out in 2002- 2003. Results: A total of 1439 uropathogens were isolated. Escherichia coli (E.coli) was the leading cause, followed by Enterobacter, and other gram negative bacilli. It was observed resistance of E.coli to ceftriaxone, cefexime, amikacin, gentamycin, and nalidixic acid; Enterobacter to cefexime; and the resistance of gram negative bacilli to gentamicin and cefexime increased significantly. The highest effective antibiotic was Imipenem, ciprofloxacin, and amikacin with 96.7%, 95% and 91% sensitivity rates, respectively, followed by ceftriaxone 77.2%, gentamicin 77%, nitrofurantoin 76.4%, nalidixic acid 74.3% and cefexime with 70%. Conclusion: The use of nitrofurantoin or nalidixic acid as initial empirical antibacterial therapy for cystitis seems appropriate. For cases of simple febrile UTI, the use of initial parenteral therapies with amikacin or ceftriaxone followed by an oral third generation cephalosporin also seemed appropriated, and in cases of severely ill patients or complicated UTI, imipenem as monotherapy or, a combination of Ceftriaxone with an aminoglycoside, are recommended

• Article: OUTCOME OF VESICOURETERAL REFLUX IN INFANTS: IMPACT OF PRENATAL DIAGNOSIS

  ABSTRACT: Introduction: The aim of study was comparing the natural history and outcome of vesicoureteral reflux in infants less than one year diagnosed prenatally or postnatally. Methods: All infants less than 12 mo old with vesicoureteral reflux were enrolled in two groups. Group 1 composed of patients with antenatal hydronephrosis and group 2, infants with diagnosis of VUR because of UTI or other postnatal problems. We followed patents for an average of 22 mo. Outcome was assessed by several factors: somatic growth, need for surgery, resolution, occurrence of UTI, scar and hypertension. Results: We studied 104 patients (155 renal units), 51 group 1, and 53 group 2 infants (59 boys, 45 girls). Occurrence of recurrent UTI and HTN was 10.6% and 1.9% respectively. Reflux resolved in 66% and improved in 13% and scar developed in 23% of renal units. Surgery was performed in six (10.6%) of patients. There was no significant difference in any of these factors between two groups. Conclusion: VUR diagnosed prenatally has similar importance and outcome as postnataly diagnosed one. We suggest performing the same imaging and treatment procedures for both groups.
