Abstract: The aim of this study is to detect the variations in cochlear size which may help in selection of the best cochlear implant electrode length and may also influence the insertion depth angles of the electrode arrays. To achieve this goal, 40 patients (21 females and 19 male) were included, their age ranged from 4 to 57 years (mean 24.63±17.30 years), pre- and post-operative non-contrast CT examination of the petrous bone was performed. It showed that, the cochlear distance (diameter A) ranged between 7.10 – 10.10mm (mean 8.53 ± 0.56mm) ,The cochlear duct length ranged between 25.50 – 38.0mm (mean 31.45 ± 2.33mm), postoperative, insertion depth angles ranged between 405 to 500o (mean 450.17±36.77), for advanced bionics, 211.0 – 420.0o (mean 367.56 ± 71.81o) for cochlear nucleus, 371.0 – 520.0o (mean 456.14 ± 61.33o) for Flex 28, and 475.0 – 598.0o (mean 513.06 ± 31.76 o) for Med-El standard electrode, a non-significant correlation was found between the insertion depth angles and the cochlear distance. A statistically significant positive correlation was found between the insertion depth angle and length of the electrode array. Therefore, it is concluded that assessing the cochlear parameters helps to choose the optimal electrode to provide proper cochlear coverage while avoiding insertional trauma.

Abstract: CNS anomalies are the second most frequent type of congenital anomalies. It is important to diagnose them as early as possible due to poor outcome. The aim of the study is to assess the role of magnetic resonance imaging in evaluation of congenital anomalies of central nervous system. This study included 80 pregnant women with suspected congenital CNS anomalies. All patients had been examined by 2D ultrasound and MRI. The majority of anomalies in the current study were anencephaly, hydrocephalus with aqueductal stenosis and Chiari malformation . Twenty percentage of brain anomalies was associated with meningioceles. A significant difference was detected in both aqueductal stenosis and dandy walker as regards history of consanguinity. The results were compared with post natal clinical assessment and MRI. It is concluded that fetal MRI is becoming an increasingly important tool in diagnosis of brain abnormalities suspected on the basis of family history or fetal sonography (with equivocal data), with continuing improvements in technology for better improvement of postnatal outcome.

Abstract: Objective: Non-Alcoholic Fatty Liver Disease (NAFLD) is a major hepatic problem in a modern –day, which, refer to a group of conditions where there is accumulation of steatosis in the liver of nonalcoholic people. It is a very common disorder which often asymptomatic. And may associated with many risk factors such as diabetes obesity and other factors. Therefore this study was conducted to determine the correlation between NAFLD and above mentioned condition using ultrasonography investigation, because that the relation of non-alcoholic fatty liver disease to these factors are not fully understood. Methods: A total of 250 Sudanese participants screening by abdominal ultrasound were used as the population of this cross-sectional prospective study, 50 out of them diagnosed with NAFLD represented the study sample. The data of the study were obtained in Sudan –Khartoum city in period from July to September 2018. Results data was analyzed to find out the correlation between NAFLD with diabetes, obesity and some other risk factors such as hypertension, elevation of cholesterol level and patient physical activities and participants were included if they didn’t have alcohol intake and their age is 20 years old and above. Statistical descriptive analysis using (SPSS) statistical package for the social sciences program was used to determine the frequency distribution of demographic variables in tables and graphs. Results: The total prevalence result of NAFLD among study population sample achieved 20% percentage and in comparing results of the total number of male and female, the gender distribution reflect that the higher percentage of fatty liver presence in male with (56.00%) percentage more than female with (44.00%) of the study sample, corresponded to maximum age range (40-49) years of group aging in the general sample of the study. Regarding to histologic and/or clinical markers of the study samples, incidence of diabetes, were (40%) with NAFLD and in correlate with patient gender, most of the diabetics are female with (22%) detection. Results for correlation of NAFLD and obesity achieved 78% detection of total study samples. Others Ultrasound results, found that there are correlation with NAFLD and many other risk factors including hypertension, elevation of cholesterol level and patient physical activity. Conclusion: Association with Nonalcoholic fatty liver disease (NAFLD) with obesity, diabetes in addition to hypertension, elevation of cholesterol level and type of patient activities as have been detected in the recent study, these findings should be taken into consideration when patient counseling and monitoring.
