Urinary incontinence is defined as involuntary loss of urine, which is a social and hygienic problem. The study is about quantity of stress incontinence in high school 15-17 years old girl during (1999-2000). This is a descriptive cross-section study. From 711 cases, 454 (76.4%) did not have urine stress incontinence (USI) and 166 (23.6%) had this problem. From these 166 members 24.1% were 15 years old, 35.8% were 16 years old and 40.1% were 17 years old. Therefore with increasing age we have more urine stress incontinence and the most prevalence of USI occur during laughing predisposing factor for USI is urinary tract infection (UTI) and trauma to hip. 27% of these girl’s mothers had USI and the population was chosen by cluster sampling. Therefore genetic factor could be a cause. The most presentation of USI is in the estrogenic phase and we didn’t have any USI report in the progestronic phase. According to our results the incidence of USI among 15-17 year girls students was 23.6%.

Background & Objective: Due to volatile property of monomer from Methylmethacrylate and its well known toxic side effects, in case of absorption via skin or respiratory system. Also, due to allergic reactions of it, consideration of suitable ventilation systems and using protective methods is very important. To decrease direct contact with it, the capabilities of technician and improves his health and work place, we investigate relationship between Methanol level and exposure to Methylmethacrylate. Materials & Methods: In a case-control (In vivo) study of 32 dental laboratory technicians in Babol and Sari before and after working and 32 normal subjects, urine samples were collected. Urine Methanol levels were analyzed by paper and gas chromatography. Results: Mean concentration of Methanol in case group (1.2 micro mol/l) was significantly more than control group (0.78 micro mol/l). Also, Methanol level was significantly higher after work (1.45 micro mol/l) when compared to before work (1.27 micro mol/l), (P<0.05). No relation between work history and urine Methanol level was observed. Conclusion: Due to significant increase of Methanol concentration during work in work place, the use of protective methods such as suitable ventilation, wearing mask and gloves, also, using vapor absorbing tubes can be useful in increasing dental laboratory workplace safety.

Background and Objective: Urinary tract infection is the most common bacterial infection during pregnancy. The pregnant women seems to be at risk for pyelonephritis and untreated infection. Timely recognition and on-time appropriate treatment of urinary tract infection particularly in pregnant women reduce the related complications. This study was done to assesse Sensitivity of isolated E.coli from pregnant women urine to antibiotics. Materials and Methods: In this descriptive study E.coli isolated from 360 urine samples from pregnant women, were examined, using Eosin Methylene Blue, blood sugar method. Antibiogram diffusion disk Kirby-Bauer was performed to assess the antibiotic response. Results: The persent of sensitivity of Escherichia coli to antibiotics were Co-amoxiclav (5.72%), Ampicillin (8.86%), Amoxicillin (11.87%), Cefazolin (32.12), Cephalexin (36.1%), Gentamicin (40.28%), Co-trimoxazole (48.15%), Nalidixic acid (55.3%), Nitrofurantoin (72.48%) and Ceftriaxone (80.78%). Conclusion: This study showed that there is a high level of E.coli antibiotics resistance toward Amoxicillin and Ampicillin high sensevity is related to Ceftriaxone and Nitrofurantoin in this region.
