Comparison of pregnancy and implantation rates in zygote intrafallopian transfer and uterine embryo transfer for nontubal infertility

We carried out a prospective randomized trial on 220 couples with nontubal factor infertility to compare pregnancy rates and implantation rates after zygote intrafallopian transfer [ZIFT] and uterine embryo transfer [UET]. The zygote was transferred by laparoscopy into the fallopian tube 24 hours after oocyst retrieval. UET was performed 72 hours after retrieval with abdominal sonography guide. Transfer was performed in 102 cycles in the ZIFT and 100 cycles in the UET group. The pregnancy and implantation rates were significantly higher in the ZIFT group [42.1% and 11.7%] than in the UET group [21.0% and 7.8%] [P < 0.05]. ZIFT could be considered for couples who have limited time and adequate financial support

[Prevalence of oxyuriasis and some related factors in kindergarten and primary school children in urban areas of Semnan province [2005]]

Oxyuriasis is one of the most common infections among children in developed and developing countries. The current study was performed to determine the prevalence of oxyuriasis [Entrobiasis] and related factors in children aged kindergarten and primary school in urban areas of Semnan province. In this cross-sectional study, 688 students were selected by stratified-random sampling and a scotch test was prepared from each student. In addition, other data were collected through questionnaire. Data analyzing was carried out by Chi-Square test and logistic regression. P-value less than 0.05 was considered statistically significant. Prevalence of oxyuriasis among children was 12.5% [8.1% in kindergarten children and 13.4% in primary school children]. The prevalence of Oxyuriasis was significantly difference in various cities of Semnan province; educated students in Damghan were in higher risk than other cities [OR = 2.47,% 95 CI: 1.26- 4.87]. In addition, the students whose thier mothers were illiterate or low education were exposed to higher risk compared to those students whose mother's education were at secondry or high school level[OR = 0.49,% 95 CI: 0.29 - 0.84] Furthermore, infrequent hand washing after toilet increased the risk of infection [OR = 1.94,% 95 CI: 1.15 - 3.26]. The risk of infection was higher among the students who had tiredness feeling in comparison with those students who did not show this symptom [OR = 2.61,% 95 CI: 1.30 - 5.25]. Moreover, the results showed that a previous history of oxyuriasis increases the risk of future infections [OR=2.73,% 95 CI: 1.58- 4.71]. These findings emphasized that personal hygiene education in mothers, especially for illiterate or low educated mothers, is necessary. It is obvious that a continuous education should be given to mothers until they achieve an appropriate level of education. This approach has more priority in Damghan

[Peritoneal benign cystic mesothelioma in a patient with presentation of ascites, a case reprot]

Cystic mesotheloma is an uncommon lesion of the peritoneum occurring predominantly in women of reproductive age. The case was a 21 years girl presented with 4 years history of mild abdominal distension and periodic pain. The results of the clinical examinations were normal. Sonography and CT scan confirmed gross ascites. The results of paraclinical tests were normal without any positive findings for etiology of acites. During laparoscopy multiple transparent cysts were found in pelvic and culdesac. All cysts were removed by laparoscopy. Histology confirmed benign cystic mesotheloma. Reviewing the records revealed that this case is the second case of mesothelial cysts that presented with ascites

[Intraperitoneal bladder rupture after normal vaginal delivery, case report]

Injuries to the genitourinary organs are complications of vaginal delivery. We report a patient with no history of surgery presented 4 days postpartum with distended tender abdomen and peritoneal sign and renal failure. Abdominal X-Ray showed a large amount of ascites. In laparotomy 3.5 liter of urine was in cavity and laceration of 3 cm in the dome of bladder was seen. Repair was done. By reviewing the record, this is the fourth case of bladder rupture after normal vaginal delivery without previous history of cesarean section. In the postpartum patient presenting with ascites and azotemia, intraperitoneal bladder rupture should be suspected

[Prevalence of intestinal parasitic infections and related factors among school children in Semnan province [2005]]

The current study was carried out to determine prevalence of intestinal parasitic infections and related factors among the pupils of nurseries and primary schools in Semnan province. In this cross-sectional study, 764 stool specimens were collected by the method of stratified-randomized sampling for stool examination. The specimens were examined by both simple smear and formalin-ether concentration methods. In addition, other data were collected through questioner and analyzed by the SPSS program and logistic regression. Prevalence of intestinal parasitic infections was%13.7 [%10.2 in nurseries and%14.2 primary schools], meanwhile, Giardia lambelia had the greatest prevalence [%8.4], followed by Entamoeba Coli [%3.2]. Intestinal Parasitic Infections [IPI] in boys [%15.6] was greater than girls [% 11.9], also the prevalence of IPI in the families with one child was significantly lower than the families with more children. Therefore, the families with 2 or 3 children and with more than 3 children were respectively 5.28 and 8.47 times more at risk of IPI, compared to the families with a child. In addition, there was a significant relationship between the occupation of pupils' father and the prevalence of IPI, as; the pupils that their fathers were building worker were 4.19 times more at risk of parasite infections, compared to the pupils that their fathers were clerk. The risk of IPI was 1.75 times more among the pupils who using fruits and vegetables that were washed only by water, compared to the pupils who using fruits and vegetables that were disinfected by antiseptic solutions in their home. With respect to the prevalence of intestinal parasite infections, no significant difference was observed between different cites and schools [with and without health instructors] of Semnan province. Since, Giardia lambelia, as a pathogenic parasite, was the most common parasite infection in Semnan province, education of the mothers and pupils about personal hygiene and prevention methods of IPI by health instructors and health centers could help to reduce the rate of intestinal parasite infections
