Traffic accidents constitute the substantial cause of disability and mortality in the young Saudi individuals reaching horrible figures. The aim of this study was to review and identify the pattern of injury among road traffic accident (RTA) victims as well as the peak time of accidents and their implications. This retrospective hospital-based cross-sectional study was carried out in the period between April 2016 to March 2017 in King Khalid Hospital, Maternity and Children Hospital and Najran General Hospital, Najran, Saudi Arabia. All RTA victims admitted to the emergency departments of the pre-mentioned hospitals. Data collected from 435 Saudis and non-Saudis' files were statistically analyzed with regard to age, gender, the timing of road traffic accidents, injury pattern, and neurological deficits incidence. Most of the RTAs' cases (92%) were male victims with the highest peak in the age group 20 -29 years. 58% of the RTAs happened in the evening (6:00 PM-9:00 PM) while 20% occurred in the morning. Head injury represented the most frequent pattern (36%) followed by the spinal injury (23%), lower limb injury (23%), upper limb injury (20%), thoracic injury (17%), pelvic injury and abdominal injury (8%). 4.4% of RTAs resulted in death whilst 9% of cases experienced neurological deficits. In conclusion, young male drivers in Najran recorded the highest frequency of RTAs. Initiation of road safety education and expansion of speed detectors (Saher) system deployment is highly recommended.

INTRODUCTIONPlacenta praevia is characterized by the abnormal placenta overlying the endocervical os, and it is known as one of the most feared adverse maternal and fetalneonatal complications in obstetrics.1 Women with placenta praevia are at an increased risk of second trimester vaginal bleeding.2 Placenta praevia is a source of drastic pregnancy, fetal and neonatal complications, e.g. peripartum hysterectomy, blood transfusion, postpartum hemorrhage, and placenta accreta for the mother, prematurity and intrauterine growth restriction for the fetus and increase in neonatal mortality rates in singleton pregnancies. 3Pathophysiology of placenta praevia is uncertain.Moreover, there appears to be an association between endometrial damage and uterine scarring and subsequent placenta praevia. We have conducted this study to find out the incidence of placenta praevia in Najran University Hospital. 4 METHODSThis study is a cross-sectional descriptive, one-year retrospective and one-year prospective study, carried out from April 2014 to April 2016. All pregnant women attended the antenatal care clinic in Najran University Hospital during the study period, were included. The data was collected in a designed questionnaire after informed consent from all patients in the prospective period.The patient's records in the retrospective period were the source of data. Abdominal Ultrasound scanning was ABSTRACT Background: Placenta praevia is a source of drastic pregnancy, fetal and neonatal complications. There was variable incidence in the literature in different parts of the world and within the same country regions. We carried out this study to find the impact in our area and the possible risk factors for this serious obstetric problem. Methods: This study is a cross-sectional descriptive, one-year retrospective one-year prospective study, carried out from April 2014 to April 2016. All pregnant women attended the antenatal care clinic in Najran University Hospital during the study period, were included. Results: The incidence of placenta praevia was found to be 2.7%. AMONG the study group, the most affected age group was between 20-29 years. Previous placenta praevia and previous caesarean section were the significant risk factors P=0.00 and 0,017 repectively. Conclusions:The incidence of placenta praevia in Najran KSA in this study was high, compared to other regions in Saudi Arabia and the majority of the international figures. Caesarean section and previous placenta praevia were the significant risk factors for placenta praevia in this study.

Background: Hypercalciuria is a common cause of urinary stone formation in both children and adults; one of the components of the comprehensive evaluation of stone formers is to measure 24 hours urinary calcium, which is a complicated method especially in children, therefore some physicians depend on calcium creatinine ratio instead of it. The objective of this study was to assess the utility of calcium/creatinine ratio as an evaluation tool for hypercalciuria in urinary stone formers.Methods: This was a case control study in which forty patients of urinary stone formers along with fifteen healthy controls group were enrolled; after fulfilling specific inclusion and exclusion criteria a questionnaire was filled, then an early morning urinary samples were collected for calcium and creatinine measurement to calculate the calcium creatinine ratio.Results: The results showed significantly higher mean value of calcium/creatinine ratio in the stone formers group compared with controls one. Also there were statistically insignificant differences in the urinary calcium between the two groups. Moreover this study showed higher mean values of both calcium and calcium/creatinine ratio in recurrent stone formers when compared with first time stone former.Conclusions: This study concluded that calcium/creatinine ratio is a useful and easier method for the initial evaluation of stone formers.
