Comparison of the outcome of trans-ureteral lithotripsy for uncomplicated ureteral stones with or without safety guidewire: A randomized clinical trial.

Introduction: Using a safety wire during trans-ureteral lithotripsy (TUL) might minimize ureteral injuries. Conversely, others suggest safety wire itself may increase the risk of ureteral injuries that its routine use is not mandatory in all cases. This randomized clinical trial was conducted to compare the outcome of TUL in the presence or absence of a safety guidewire.

Prevalence of the genital tract bacterial infections after vaginal reconstructive surgery.

Due to frequent childbirth, heavy lifting and the structure of the lives of rural women in Shahrekord region, Iran, cystocele and rectocele are of the main medical problems of the women in this area and for its correction, vaginal reconstructive surgery is needed which causes infection. The purpose of this study was to identify the bacteria causing infection after vaginal reconstructive surgery and performing antibiogram to help these patients for faster recovery. Patients enrolled this study were 92 who had undergone previous vaginal reconstructive surgery and now had infection.

Analysis of Relationship between Tumor Necrosis Factor Alpha Gene (G308A Polymorphism) with Preterm Labor.

Background: Increased concentrations of tumor necrosis factor alpha (TNF-α) in blood and amniotic fluid are observed in women with preterm delivery (PTD) and TNF-α mutations at -308 position are associated with higher expression of this gene. Therefore, we compared the frequency of G308A transition in the promoter region of TNF-α gene of women and neonates delivered preterm with the normal subjects.

Methods: This cross-sectional study was performed on 135 mothers who were referred for delivery.

Effects of antenatal corticosteroids on maternal serum indicators of infection in women at risk for preterm delivery: A randomized trial comparing betamethasone and dexamethasone.

Objective: To compare the effect of betamethasone and dexamethasone on maternal white blood cell (WBC) and differential count, erythrocyte sedimentation rate (ESR), Apgar score, maternal and fetal plasma glucose and length of admission to delivery, gestational age at delivery in women at risk of preterm labor (PTL).

Study Design: Two hundred and forty pregnant women at risk for PTL with intact membranes or preterm premature rupture of the membranes (PPROM) were randomly allocated to receive either two intramuscular injections of 12 mg betamethasone at 24-h intervals or 4 injections of 6 mg dexamethasone at 12-h intervals. Blood tests for WBC and differential count, ESR and fasting plasma glucose were drawn before betamethasone or dexamethasone injection and after injection every 24 h for two days.

Effects of zinc supplementation during pregnancy on pregnancy outcome in women with history of preterm delivery: a double-blind randomized, placebo-controlled trial.

Objectives: The aim of this study was to assess the effect of high dose zinc (Zn) supplement during pregnancy in pregnancy outcome in healthy pregnant women with a previous preterm delivery in Isfahan, Iran.

Methods: A double-blind placebo-controlled randomized clinical trial was conducted between January 2007 and June 2008. Eighty-four pregnant women with a previous preterm delivery age 19 to 35 years were randomly allocated to receive either 50 mg/day Zn as Zn sulfate or placebo from 12 to 16 weeks of gestation till delivery.
