Primary retroperitoneal synovial sarcoma in CT and MRI

Synovial sarcomas are most commonly localized in the extermities, especially the lower thigh and knee areas. Retroperitoneal synovial sarcoma is very rare. We decribe the radiological findings of an adult retroperitoneal synovial sarcoma

Early morbidity and mortality after retroperitoneal repair of the abdominal aorta with modification of the patient's position

Repair of the abdominal aorta is a major procedure that has a considerable morbidity and mortality. Efforts are exerted to reduce this operative risk, one of which is the surgical approach of the Aorta. This study was carried out to evaluate the retroperitoneal approach regarding morbidity and mortality during the operation and for 30 days afterward and to evaluate the accessibility of this approach while the patient in supine. Nineteen patients with a mean age of 65.5 years were admitted for the repair of Abdominal Aorta between March 2004 and March 2006. To repair the Aorta of these patients it was approached retroperitonealy, using the standard technique with modification of the patient's position. Operative and post-operative data were measured and compared to the literature. Mean operative time, intra-operative fluid replacement and ICU stays were less compared to the transperitoneal approach. Normal intestinal sounds were regained after 2 days in most of the patients. Mean hospital stay was 6.7 days with no mortality. This study supports that retroperitoneal approach has early morbidity and mortality that is comparable to the accepted rate of complications in literatures. This approach provides a convenient exposure to treat different anatomical lesion of the distal Aorta and iliac arteries, when we operate with the patient in the neutrally supine position

Correlation between caries risk factors and caries development in a group of preschool children

Dental caries is a multifactorial disease, thus the clinical outcome varies depending on which factor, or combination of factors, is promoinent in a particular individual. Thus it is wise to target preventive programmes to those group who are classified as high caries risk subjects to minimize cost and man power. In this study we tried to highlight on the most accurate factor [s] which can be used as indicators for future caries. Among 43 children, only 34 children of both sexes completed the study, with main age 56 +/- 5.4 months. For each child complete dental examination including dmfs and oral hygiene index were taken. Diet history analysis was also taken. Salivary Streptococcus Mutans, lactobacilli as well as rate, buffering and viscosity of saliva were also meassured. This was followed by complete dental treatment [if needed] and a preventive dental programme. After one year follow up, it was found that the most effective caries risk indicators were Streptococcus Mutans, number of food snakes per day, past and present caries experience and the younger the child with caries, the higher the risk for development of caries

Clinical evaluation of three different materials used as pit and fissure sealants

Fissure sealant is a well established comonent in prevention of dental caries of the occlusal surface in the newly erupted molars. The purpose of the present study was evaluate the retention and caries-preventive effect of a glass ionomer cement [Vitremer], a flowable compomere [Dyract Flow] and a flowable composite [Tetric Flow]. 160 first molars of 40 children aged 6-8 years with mean age 7.25 +/- 0.4 years of both sexes completed this study. Their lower and upper first molars had been newly erupted. They were previously classified as a high caries risk group as they had dmfs not less than 4 surfaces. They were divided into 4 equal groups. 10 children in each group had only one type of a sealant. The other 10 children were the control group. All children and their parent were educated how to use oral hygiene methods as well as proper diet to control caries. It was found that Tetric flow had the best retention followed by Vitremer and finally Dyract Flow had the least retention. While for caries development, control group showed at the end of the study 34 sound molar, Dyract flow group had 36 sound molar, Vitremer group had 38 sound molar while Tetric Flow had 39 sound molar. It was concluded that flowable composite is superior in its use as a fissure sealant followed by glass ionomer cement and finally compomer is not that good as a fissure sealant material

Oral hygiene behaviour of school children of different socioeconomic status in ismailia city

This study had been conducted to assess oral hygiene status, gingival health status and oral hygiene habits among school children of both high and low socioeconomic status in Ismailia City. A total of 1335 school children aged 11<14 years attending preparatory schools were included in the study. Children were grouped according to socioeconomic status, age and sex. Oral hygiene status and gingival health status were assessed using OHI-S and Gingival Index respectively. Oral hygiene habits as brushing frequency, timing of brushing and use. of other oral hygiene measures [miswak] were investigated. The results of this study showed that children of high socioeconomic level had better oral hygiene and gingival health than children of low socioeconomic level. Mean OHI-S and GI scores reached a peak at 13<14 in boys and 12<13 in girls. Girls of high socioeconomic group had better oral hygiene and gingival health than boys, and reverse was found in low socioeconomic group. Children of high socioeconomic level were found to brush their teeth and use miswak more frequently than children of low socioeconomic level. A multivariate study showed that oral hygiene was affected sequentially by following factors; brushing frequency, socioeconomic status and timing of brushing. While gingival health was found to be affected by socioeconomic status, brushing frequency, estimated age, and timing of brushing

Clinical, radiological and ultrasound study of clicky hips in neonates

32 full term newly born Saudi babies, 25 females and 7 males. The study comprised 15 cases as control. 17 cases were referred to the orthopaedic department due to clicky hips; 7 of the latter were bilateral. Barlows and Ortolain tests were used for examination of the hips. Radiological: Plain X-rays of the pelvis and hips were done in all cases. Ultrasound: Coronal section was obtained for each hip joint, alpha and beta angles were measured as well as the femoral head diameter, containment of the femoral head, cartilage covering, labrum and ligamentum teres and also shape of promontory. t-student test, F ratio, chi square and r test were used. Monthly clinical and ultrasound follow up examinations were performed. showed that the ultrasound examination of the hips proved valuable and superior to the other methods and is considered a sensitive tool in detecting any changes in the neonatal hips

role of postoperative irradiation in intracranial menlngloma

Ninety five patients with intracranial meningioims were included in this study. Total surgical removal was done in 51 patients and partial removal was done in 44 oases. Postoperative radiotherapy was applied in 63 oases depending on the extent of surgery and/or histologioal findings. Objective complete response was achieved in 67/95 of the cases. The 5 year actuarial survival rate was 93.8% in -cases with limited disease treated by complete removal alone, 89.5% in malignant types treated by complete removal and postoperative radiotherapy and 87.5% in patients whose tumours were incompletely removed and treated by radiotherapy
