Introduction : Premature rupture of membranes (PROM) occurs in 10% of pregnancies , while 3-5% of pregnancies are complicated with Preterm rupture of membranes (PPROM) . Aim : To study the role of uterine cervix injuries in PROM . Materials and Methods :This is a case-control retrospective study conducted at Obstetrics and Gynecology Department at Al-Assad and Tishreen University Hospitals , Lattakia , Syria , during the period between January 2015 – July 2017 . The case group consisted of 90 PROM patients with a history or a physical examination suggesting a cervical traumatic injury after exclusion the traditional risk factors of premature rupture of membranes, The control group consisted of 50 healthy pregnant women who successfully completed the pregnancy without PROM.

The study is carried on 65 pregnant patients attending the outpatient clinics and inpatient department of Obstetrics and Gynecology of Al Assad University Hospital from February- 2013 until February- 2014. They were divided to three groups. The fir st is preterm labor with intact membranes (25 patients). The second is PROM (20 patients). The third one is control group (20 patients). All of them were submitted to ultrasonography to find cervical changes (cervical canal length and diameter of internal os in order to predict preterm delivery. Cervical canal length has a sensitivity of 91.43%, a specificity of 100%, a positive predictive value of 100%, a negative predictive value of 76.92%, and a relative risk (95% CI) of 4.33 (1.61-11.69) among patients with short cervical canal length and those with normal cervix. Diameter of internal os as a predictor of preterm delivery has a sensitivity of 60%, a specificity of 60%, a positive predictive value of 84%, a negative predictive value of 30%, and a relative risk (95% CI) of 1.2 (0.86–1.68).
Mankind is still suffering from many diseases , and with the development of civilization there are many diseases that appear with different clinical types , but tumors, especially malignant , are still very important. Cervical cancer is the secon d common cancer in women , as it is the cause of more than 200.000 deaths annually. Hence the importance of early detection of cervical cancer and of decreasing mortality.
The research was conducted in the department of obstetrics and gynecology at Al-Assad university hospital in Lattakia in the period between (1/1/2014) – (30/6/2015). The study included (100) patient, who submitted to colposcopy and Papanicolaou smear to detect the effect of early marriage (early onset of sexual activity) on colposcopic and cellular finding in cervix . The results in (early married women) group (50) patient were compared to control group from patients who (not early married women)group (50) patient. We found that there was important difference in the rate of abnormal colposcopic findings : This rate in early married women was (26%) and in the second was (12%). We also found that there was important difference in the rate of abnormal cellular findings: This rate in early married women was (18%) and in the second was (8%). This assure the effect of early onset of sexual activity (early marriage) on colposcopical and cellular finding in cervix with assuring on the importance of frequent colposcopy and Papanicolaou smear test.
Cervix cancer is one of the most important gynecological cancers ,which is possible to be reduced by using early precancerous detecting technics . Objective : The aim of the study is to highlighten the colposcopy as a device for early detection o f precancerous lesions in the cervix , and compare the results with histopathology .
This paper presents the application of electromagnetic wave scattering in human cervical cells. Particularly, studying the effect of morphological and physiological alterations on the properties of light scattering. Tissue alterations are caused b y multi-grade dysplastic cervical cells and its internal structures.
