Tabriz-Marand road is one of the important connecting networks in Iran which is not only significant inner and communications but also in abroad relations. This road rests on loose Quaternary formations and sometimes experiences landslides. The aim of this paper is to identify areas which are susceptible to slides. This paper evaluated the natural disasters that are threatening the confine of Tabriz-Marand road and railway, with the use of different data such as lithology, the slope of foothills, land use, land cover, the distance from linear features (road, river, and fault) and overlaying of them, with the emphasis on landslides and using remote sensing and GIS capabilities.

Legg-Calve-Perthes disease is one of the most common disabling diseases of childhood and if not managed appropriately is truly disabling. Severity of disease and duration of disease onset are main determinants of choosing treatment strategy of either conservative management or surgical treatment. This study was designed to determine Legg-Calve-Perthes treatments and relation between type of treatment and duration of the disease. This descriptive study was carreid out on 50 patients with Legg-Calve-Perthes disease admitted in Ghaem Hospital in Mashhad, North East of Iran from 1995-2005. According to age of patients and severity of disease, the subjects allocated to conservatine (11 patients) and surgical treatment (39 patients). Clinical improvment signs include pain reduction, range of joints motion, which were avaluate by physical examination and taking medical history of patients. In conservative group, only 4 patients assumed to be successfully treated with mean age of 7.25 years and the mean interval between disease onset and beginning of treatment was 2.25 months. Surgical group had mean age of 10.85 years and mean interval between onset of disease and initiation of treatment was 18 months. Conservative group showed less sever form of disease (lateral pillar group A and group B with age less than 8 years), but patients treated surgically were more severely involved (lateral pillar group B with age more than 8 years and group C). This study showed that age and severity of disease (lateral pillar classification) are main elements in treatment strategy (choosing conservative VS surgical treatment). The interval between onset of disease and onset of treatment strongly affects treatment success.

Gestational diabetes, the most common metabolic disorder in pregnancy, causes serious complications in mothers and their fetus. So, knowing the risk factors of gestational diabetes is very important, because through understanding these risk factors it helps to establish screening programs for susceptible mothers and also early diagnosis of disorders. Furthermore, efficient control of blood sugar protects mothers against complications and consequently their fetus. The goal of our study was to evaluate the correlation between gestational diabetes and polycystic ovary syndrome. This study was a case - control research. Pregnant women admitted at Akbar Abady hospital of Tehran were studied during 1998-2005. 188 women participated in this study of whom 94 mothers were put into the case group (with gestational diabetes) and the other 94 mothers were in the control group (without gestational diabetes). Then history polycystic ovary syndrome was investigated between the two groups. The data were analyzed using SPSS software, descriptive statistical, t- test, fisher, x2, Mann- Whitney and Odds ratio. The results of this study showed no dissimilarities between the two groups regarding the mean of age, educational level, apgar score and gravida. But there was significant difference in history olligomenorrea, kind of delivery, mean of the new-born weight and gestational age and body mass index in the two groups. Also, the results showed significant relations between those with gestational diabetes and women without gestational diabetes with the history of polycystic ovary syndrome. (p=0/03)Discussion & Considering the results of our study indicating significant relations between diabetes and history of polycystic ovary syndrome, it seems necessary to establish screening programs in women with history of polycystic ovary syndrome, while early diagnosis of gestational diabetes protects mothers and their fetus against any complications.
