Abstract
Background: Carpal tunnel syndrome is the most common focal neuropathy that results from pressure on a nerve. The goal of this study was to assess carpal tunnel syndrome and its associated factors such as occupation, sex, and accompanying complications in a teaching general hospital.
Methods: This cross-sectional study investigated 362 patients with the diagnosis of carpal tunnel syndrome admitted in the orthopedic ward of Imam Khomeini Hospital affiliated to Tehran University of Medical Sciences in Tehran, Iran during 2000-2010.
Results: The difference in the mean age of men and women was statistically significant (P<0.0001). The percentage of men with the disease was significantly different from that of the women. The prevalence of idiopathic carpal tunnel syndrome was significantly different (P<0.0001) in comparison with carpal tunnel syndrome due to its leading causes. The most common occupation in women was first housekeeping and then hairdressing while in men it was being a worker. Diabetes Mellitus and hypothyroidisms as the leading causes of the syndrome were highly correlated with the disease (r=08, P<0.001).
Conclusion: According to the findings, most cases of the syndrome were idiopathic. Identifying the leading causes of the disease is important because their diagnosis probably prevents unnecessary surgery. By identifying such causes and/or correction of activity styles incidence of carpal tunnel syndrome and unnecessary surgical procedures would be prevented. Evaluation of patients for underlying causes can be useful, especially in severe forms of the disease to realistically assess the need for surgical treatment.

Abstract
Background: Early detection of fetal gender can provide an alarm for parents who complicated by genetic disorders. Moreover, the invasive tests are used for detecting any sex-specific genetic syndromes before 12 weeks of gestation. This study was de-signed to discover any association between placental location and fetal gender between 11 to 13+6 weeks of gestation.
Methods: A cross-sectional study was conducted on 200 singleton pregnant women. They were referred for Down syndrome screening sonography to prenatal clinic, Imam Khomeini Hospital a tertiary referral university affiliated hospital, Ahvaz, Iran, in 2013. Women were included if they are singleton and at 11 to 13(+6) weeks gestational age. Exclusion criteria were multifetal, ectopic pregnancies, or dead fetus. Information about placental location (upper, middle, below, anterior, posterior), gravidity, and fetal gender were recorded. All participants of our study were evaluated by one trained gy-necologist in ultrasound examinations during nuchal translucency (NT) examinations. Ultrasonography was performed using the Accuvix V10 OB/GYN ultrasound. All patients were followed-up till delivery for confirming the predicted gender. Information regarding gender of newborn were collected using medical chart review or by phone contact.
Results: Among 200 placenta which had been assessed, 103 (51.5%) were anterior and 97 (48.5%) were posterior. Our results showed that 75 (72.8%) from girl cases had an anterior placenta, while just 28 (27.2%) from boy cases had an anterior placenta (P< 0.001). In addition, there was significant association between placental location regard-ing below, middle, and upper and fetal gender.
Conclusion: According to our results, an anterior and posterior positions of the placen-ta had significant relation with fetal gender. Our findings are consistent with previous studies regarding prediction of fetal gender using placental location. We suggest that more research with large sample size is required as well as investigations with more de-tails about placental locations.
