Background and Objective: Pregnancy in the early years of reproductive period has been considered as a high-risk pregnancy. Since different factors interfere with pregnancy and its outcome in teenagers, this study was conducted to determine the outcomes of pregnancy and childbirth in adolescents in Dezyani Hospital of Gorgan, Iran (2008). Material and Methods: In this retrospective case-control study, we compared the pregnancy outcome of 91 primigravida teenagers (less than 19 years) with that of 89 women (19-29 years) as control group. The data collected from patients medical records are mother's age, gestational age, and fetal presentation , gestational hypertension, diabetes mellitus, the way of delivery, hemoglobin status before and after childbirth, first and fifth minute Apgar scores, neonatal anthropometric indices, mode of delivery, congenital anomalies. Data were analyzed with descriptive-analytic tests, using the SPSS.16 software. Results: The mean age of the case and control group is 17.73±1.30 and 24.56±2.54, respectively. In admission, young mothers have significant more weight and height (p<0.05). Mean gestational age is almost the same in teenage (38.59±3.15week) and young mothers (38.09±3.0week). Neonatal anthropometric indices and first and fifth minute Apgar scores are not significantly different in two groups. Conclusion: Mother's age can not be the only determinant of the outcome of pregnancy and childbirth. Pregnancy in teenagers isn't associated with the decrease of gestational age, anthropometric indices and Apgar score, and is not related with the increase of early childbirth and maternal and neonatal mortality.

  Background and Objective: Mechanical ventilation is used for some infants in neonatal intensive care unit (NICU) due to many physiological and clinical causes. The practice of endotracheal suctioning of ventilator- treated patients is necessary to remove secretions to prevent obstruction of the endotracheal tube and lower airways. This study aimed at determining the effect of open and closed suctioning methods on cardio-respiratory parameters of infants undergoing mechanical ventilation.

  

  Material and Methods: In this clinical trail, forty-four infants underwent mechanical ventilation in NICU were selected by simple continuous sampling. The samples were randomly divided into two groups. In the first group: first, open suctioning and then after three hours of cleaning, closed suctioning was performed. In the second group, first closed suctioning and after three hours of cleaning, open suctioning was implemented. Respiratory rate (RR), oxygen saturation, pulse rate and blood pressure were assessed before ( in three, two and one minutes ) , during and after ( in one , two and three minutes ) each type of suctioning. The Data was analyzed by Software SPSS-16 using ANOVA with repeated measures and independent t-test.

  

  Results: There was a significant difference between mean respiratory rate and oxygen saturation in infants during and after the closed and open suctioning (p<0.05). Oxygen saturation had a significant reduction in open method compared to closed method during and immediately after suctioning. Respiratory rate had a significant reduction in 3 minutes after open suctioning in both steps. The mean of diastolic pressure in second step of open method and in both steps of closed method was significant (p<0.05). There was a significant difference between the mean pulse rate in different times of open suctioning in the first step (p<0.05), Pulse rate drop significantly was lower in closed suction than open one (p<0.05).

  

  Conclusion: because of little changes caused by closed suctioning in hemodynamic condition, it is recommended using the closed suctioning to prevent from respiratory complications and pulse rate dropping in infants.

  Background and Objective: ­ Urinary tract infection is one of the most common bacterial infections during pregnancy and has also been implicated as a risk factor for adverse maternal and prenatal ­­outcomes. The aim of our study was to determine the relation between maternal urinary tract infection and adverse maternal, prenatal outcomes in pregnant women of Ardabil, Iran.

  Material and Methods: ­ This retrospective-case-control study was conducted on­ prenatal file records of pregnant women in Ardabil (2011). ­ ­The pregnant women ­who had a positive urine culture in their prenatal files­ (N= 211) ­were considered as a case ­group and ­232­ ones without urinary tract infection as a control. Using a research- made questionnaire, the data related to present pregnancy and prenatal information was collected and analyzed by KrusKal Wallis, Chi- Square and Fisher statistical tests.

  Results­: Maternal age of under 25 (%61.6 vs. 56.5), body mass index of more than 30 (%18.3 vs. 15.6), primigravida (%55 vs. 48.8), hypertension (%2.4 vs. 1.3), hyperemesis Gravidarum (%14.8 vs. 12.6), frequency ­and dysuria ­(%1.9 vs. 0.9), low birth weight (%95.4 vs. 93.2), congenital malformation (%3.5 vs. 1.8), artificial milk feeding (%6.5 vs. 2.7), neonatal death (%0.9 vs. 0.0) are higher in urinary infection group, however the differences are not statistically significant. Other maternal and prenatal adverse outcomes such as diabetes, pre-eclampsia , hemoglobin level, prematurity, abortion and stillbirth have not significant relation with urinary infection.

  Conclusion: Because of low level of adverse maternal or prenatal outcomes reported in our study, we conclude that screening and treatment of urinary tract infection in Ardabil health service is ­appropriate therefore, ­no change is needed for present ­screening­ or treatment processes.
