Congenital hypothyroidism is the most common preventable cause of mental retardation in children and should be diagnosed and treated at the earliest time. The prevalence of congenital hypothyroidism is high in preterm infants with low and very low birth weight.
A systematic literature review was conducted using PubMed, Scopus and Google Scholar databases to 19 April 2014. We did not consider any time limitation; English-language papers were included. Irrelevant studies were set aside after studying their title, abstract, and full text. Two reviewers extracted the data; besides, the third reviewer checked their extracted data. In final, the data extracted from related studies.
Findings: Normal serum thyroid-stimulating hormone (TSH) at third to sixth days of birth in low- and very-low-birth-weight preterm infants did not indicate normal thyroid function. In addition, TSH level of more than 10 mIu/l at the second week of the birth did not have a diagnostic value. A TSH level of 10-15 mIu/l, after a normal TSH value, posed the diagnosis of hypothyroidism with delayed TSH rise. Serum levels of free-T4 (FT4) and T4 would be normal at 2 to 8 weeks after the birth.
It is recommended to repeat the screening of preterm newborns with low and very low birth weight by measuring TSH and FT4 levels simultaneously at two, six and ten weeks after the birth; the threshold of TSH = 10 mIu/l should be considered to select positive and suspected cases of the disease.

Care of the low birth weight (LBW) neonates in incubators is accompanied with effects such as delay in weight gain، prolonged hospitalization and caused hospital infections accordingly. One of the substitutive methods of incubator care is natural and non-invasive kangaroo mother care (KMC) in which infant are in skin-to-skin contact whit mother. In this study، it was aimed to review the effect of kangaroo mother care on weight gain، stay length and control of temperature with low birth weight in preterm neonates. This clinical trial study was conducted on preterm neonates with the history of birth weight lower than 2500 in neonatal intensive care unit (NICU) of selected hospitals in Moshhad، Iran، in 2010. Fifty neonate were selected regarding to purposive sampling and were assigned into two groups (25 in intervention group، and 25 in control group). In the intervention group، infant and mother have skin-to-skin contact one hour a day. In the control group، the infant cared and fed according to routine schedule in NICU unit. The temperature degree was measured in two periods. The data were analyzed by chi square، independent t-test and analysis of variance (ANOVA) repeated measurements. The mean of weight changes in the KMC group was 15g and 4g in control group which were statistically significant difference between the two groups (P = 0. 015). The mean staying period in the KMC group was 7. 9 and 10. 6 in control group which was statistically significant difference between the two groups (P = 0. 03). The changes of temperature in the two groups were not statistically significant. KMC method had positive effect on gaining weight of preterm neonates and reduced hospitalized days in the NICU. It is recommended that health authorities act towards training KMC method to nurses and healthcare team members as obstacles to be overcome.

Low birth weight (LBW) is the most common problem that is considered as the only means of measuring the outcome of pregnancy. This research was designed in order to evaluating the effect of mother consulting on weight gain of low birth weight neonate in the educational hospitals of Ardabil University of Medical Sciences in 2011.

In this study 74 mother of low birth weight neonate with age range of 15 to 45، with literacy، and not addicted، gestational age of 36 weeks or more and newborn with birth weight of 2500 grams or less، without having congenital anomalies or diagnosed disease that had been discharge with her mother and without any contraindication for the breastfeeding، were randomly assigned to two groups، consulting (n=37) and common education (n=37) were placed. In case of hospitalization during the study and if breastfeeding neonate by mother، is impossible، these infants were excluded. Mothers during the five sessions of counseling received necessary training and were controlled infants weight by using Seca scales during the meeting. Scales and questionnaires were used for collecting data and software SPSS- 17 used for data analysis.

Average of birth weight was 2416. 21140. 46 gr in consulting group and 2367. 56172. 79 gr، in common educational group. After the end of study، the average weight in consulting group was 3618. 91394. 38 and in common educational group was 3168. 10368. 62 (P=0. 007).

The findings of this research show that consulting with mothers can be an effective method for making easy the growth of neonates.

Teenage pregnancy is known as a high risk pregnancy. However, some study show that good prenatal care can decrease the rate of complications. This study was done to evaluate the frequency of preterm labor, still birth, premature rupture of membranes, cesarean section, eclampsia, low birth weight and interest of mother's about the type of delivery. This study was conducted from October 2009 to November 2010 in Isfahan University of Medical Sciences, Isfahan, Iran. Five hundred mothers were followed during their pregnancy and were divided into two groups, under 20 years (teenagers) and-over 20 years. The complications and outcome of pregnancy were evaluated and the collected data was analyzed by SPSS16. Five hundred pregnant women were evaluated during their pregnancy. The mean age of teenage women was 18.12 ± 1.11 years and the mean age of over 20-years mothers was 26.53 ± 3.08 years. 15(6%) teenage women have experienced eclampsia, while only 4(1.6%) women over 20 years old had eclampsia (P = 0.01). This study showed that teenage pregnancy has more complications than older age, and more education is needed to reduce this type of pregnancy.

After Iraq-Iran war the community encountered with many of the war wounded who suffer from the outcome of the chemical gases which were used by Iraq.These outcomes are divided into early and late complications. Reproductive outcomes such as spontaneous abortion, low birth weight and preterm labor are delayed outcomes there are limited stuies about these outcomes. The aim of this study was to survey pregnancy outcome in wives of the chemical war Wounded and to determine the relation between chemical gas exposure and such results as low birth weight, preterm labor, intra uterine fetal death, fetus abnormality and altered sex ration. We randomly sampled 50 chemically injureds from 2100 chemically injureds in Keman and obtained questionnaire data concerning chemical gas exposure and reproductive health experience. In these 50 selected chemical victims, there were 120 pregnancies, there were 19% LBW, 13% Preterm labor and 8% abortion, low birth weight, Abortion and preterm labor correlation with mothers and fathers age, education and severity of chemical injuries were analyzedin SPSS system. Except for parent’s age, in other variables P were less than 5% suggesting that the relationship is significant.
