However, the partial deletions of AZFc region related to spermatogenetic impairment are controversial. We investigated partial deletion of AZFc region and DAZ copy number in a population of Iranian infertile men and normozoospermic controls. In total, 154 infertile men (113 patients with azoospermia, 41 with oligozoospermia) and 111 normozoospermic controls were analysed using PCR. Gene dosage analysis of the DAZ genes was performed by fragment analysis. Our results showed that the frequencies of gr/gr deletion in the azoospermic, severe oligozoospermic and normozoospermic men were 4.4% (5/113), 7.3% (3/41) and 1.8% (2/111) respectively. In the azoospermic patients, the frequency of b2/b3 was 1.8% (2/113). Partial AZFc deletions were not significantly different between the infertile and normozoospermic men. The frequencies of gr/gr deletions and b2/b3 were not significantly different between the azoospermic/severe oligozoospermic men and normozoospermic controls. Our data suggested that gr/gr deletion was not associated with azoospermia/oligozoospermia in an Iranian population.

HWS is a safe and effective method for RPL and infertility cases with statistically significant improvement in pregnancy chances and reproductive outcomes. With regard to the persisting uncertainty around the effectiveness of septum resection in recurrent miscarriage and infertility cases, there may be alternative methods to better address the pathophysiology of septum. There are different explanations for the poor reproductive performance with uterine septum: poor vascularisation of a highly fibrous implantation site, low sensitivity of endometrial receptors covering the septa, its “myoma-like” composition, and finally higher uterine vascular resistance. Complete removal of this abnormal tissue rather than just incising it may not only enhance challenging the pathogenesis bu...

Since the seasonal pattern in preterm birth varies across countries and because of importance of preterm births and unknown causes of it, this study was designed to investigate the frequency of preterm births in different seasons. Materials and Methods: This cross-sectional study used data of all 5,860 infants born in the Rafsanjan Nik-Nafs hospital in 2011-2012. Inclusion criteria included live birth more than 20 weeks gestational age and birth weight more than 500 grams. Gestational age was determined according to mother's last menstrual period date. The criterion for preterm birth was gestational age less than 37 weeks gestation. Data was collected through delivery records of hospital medical documentary unit. For data analysis, chi-square and Fisher's exact tests was used. Results: The prevalence of preterm birth in this study was 6.96% (408 cases)...

Since health outcomes differ on ethno-racial groups and there is little information among hand with regards to the said matter in Iran, this study was designed to survey the preterm and low birth weight prevalence on Iranian and Afghan nationalities. Materials and Methods: This cross-sectional study was carried out on 5925 Iranian and Afghan live births which delivered in Rafsanjan Nik-Nafs hospital on 2011-2012. Data was collected via use of delivery records of hospital medical documentary unit. The criterion for preterm birth was gestational age less than 37 weeks, and for low birth weight was birth weight less than 2500 grams. For data analysis, independent two-sample t-test, chi-square and Fisher's exact tests were used. Results: overal, 5532 infants (93.4%) were Iranian and 393 infant (6.6%) were Afghan. Preterm birth prevalence was 7.5% (447 cases), so that 7.1% (391 cases) and 14.5% (56 cases) were Iranian and Afghan respectively (p<0.001). In the present study, low birth weight prevalence was 7% (416 cases) out of which 6.7% (367 cases) were Iranian and 12.7% (49 cases) were Afghan (p<0.001). Conclusion: Since high prevalence of preterm birth and low birth weight were seen among the Afghan refugees, it appears that race and different factors such as: lack of proper insurance, availablity of health services and a lower socioeconomic status are in linked with this increase.

Hence, knowledge of maternal diseases can be considered as an effective factor in maintaining infant ideal weight. Therefore, this study was addressed to investigate the association between maternal diseases and birth weight. Materials and Methods: This descriptive study was conducted on Rafsanjan-Niknafs maternity in 2011-2012. The inclusion criteria were being Iranian, live births, gestational age of 22 weeks and above and birth weight of >500 g. Data were collected by questionnaires and analyzed by statistical tests including independent t-test, chisquare test, Fisher's exact test, one-way ANOVA and multiple linear regression. Results: In given sample, 4193 (83.6%) mothers were healthy and 825 (16.4%) mothers had underlying diseases. The average and standard deviation of age in healthy and diseased mothers were 27.37 ± 5.14 and 29.99 ± 5.59 years old, respectively (p<0.001). There was found a significant difference between mother's diseases and birth weight, as infant weight gain of healthy mothers was 89 (2.2%), of diabetics 25 (5.8%), of the hypertensive 10 (4.4%), and of mothers who had more than one disease 4 (5.8%) (p<0.001). Also, low birth weight (LBW) in healthy mothers, in mothers with diabetes, hypertension, and in mothers with more than one disease was 6.3%, 4.9%, 17.8%, and 7.2%, respectively (p<0.001). Conclusion: Given the high prevalence of weight disorders in Rafsanjan and the impact of mother's diseases on this important health index, it is necessary to identify and provide special control care for mothers during pregnancy.

Since incidence and cost of treatment of the cancer are increasing, it is necessary to further investigate to prevent and control this disease. This study aimed to determine skin cancer trend and epidemiology in Iran. Methods: This study was done based on existing data. Data used in this study were obtained from a national registry of cancer cases and the Disease Management Center of Ministry of Health in Iran. All cases registered in the country were included during 2004-2008. Incidence rates were reported based on the direct method and standard population of World Health Organization. Results: Based on the results of this study, the incidence of skin cancer is rising in Iran and the sex ratio was more in men than women in all provinces. The age-standardized incidence rate (ASR) of skin cancer was highest in males in Semnan, Isfahan, and Hamedan provinces (34.9, 30.80, and 28.84, respectively). The highest ASRs were seen in females in Semnan, Yazd, and Isfahan provinces (26.7, 24.14, and 18.97, respectively). The lowest ASR in male was observed in Sistan and Baluchestan, and in female in Hormozgan provinces. Conclusions: The incidence of skin cancer is increasing in the country. Therefore, the plan for the control and prevention of this cancer must be a high priority for health policy makers.

In light of the increasing use of pesticides and growing concerns about the possible health effects of agricultural pesticides, we investigated the effect of exposure to pistachio pesticides on stillbirth in pregnant mothers. METHODS: This case-control study was conducted in Rafsanjan, Iran from 2011 to 2012. A total of 125 females who had a recent stillbirth were included as the case group, and 250 controls were selected from females who had a recent live birth. For each case, two controls with the nearest propensity score to the case were selected. Data were collected using a protocol developed by the researcher that involved interviewing respondents and reviewing their medical records. Conditional multivariate and univariate logistic regression analysis were performed and odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. RESULTS: The ORs of stillbirth in mothers living in pistachio gardens and those who were exposed to sprayed pesticides, in comparison to the controls, were 14.1 (95% CI, 3.3 to 63.4) and 5.0 (95% CI, 1.2 to 28.6), respectively. No significant differences were found in stillbirth rates according to the distance between the mother's residence and a pistachio garden or involvement in agricultural activities. CONCLUSIONS: The results of our study showed that exposure to pistachio pesticides during pregnancy may increase the likelihood of stillbirth in mothers.

RESULTS: The ORs of stillbirth in mothers living in pistachio gardens and those who were exposed to sprayed pesticides, in comparison to the controls, were 14.1 (95% CI, 3.3 to 63.4) and 5.0 (95% CI, 1.2 to 28.6), respectively. No significant differences were found in stillbirth rates according to the distance between the mother's residence and a pistachio garden or involvement in agricultural activities. CONCLUSIONS: The results of our study showed that exposure to pistachio pesticides during pregnancy may increase the likelihood of stillbirth in mothers.
