Abstract: The importance of Inferior alveolar Canal lies in that it may be positioned at different locations in the mandible, where the mandibular nerve bundle passes through and may be damaged during dental implantation. The researchers characterized the Inferior alveolar Canal in order to avoid injury during the maxillofacial surgery or during dental implant procedures in both sides of the mandible and in both genders and compared the variables in the Sudanese population with those reported in other nations. The study consisted of two hundred and two Orthopantomograms which were collected and analyzed; five measures were selected and studied for right and left sides of the jaw for males and females. The distances were measured in millimeters: distance between superior border of Inferior alveolar Canal and second molar, second premolar and alveolar bone, height of Inferior alveolar Canal and the distance to the mandible border. The collected data were then correlated with age and gender. The results showed that the measured distances were correlated linearly with age in both genders, and no significant differences were detected when comparing both sides of the mandibles in both genders. Significant differences between males and females measurements were detected and also in the Sudanese and other populations. The research has come out with findings that Orthopantomogram is suitable radiological method to characterize the location of Inferior alveolar Canal for Sudanese population as the knowledge about the canal anatomical variations is essential in order to avoid complications during dental surgery or treatment.

Abstract: Cranial Ultrasound is the most available and easily repeatable technique for imaging the neonatal brain. The quality and diagnostic accuracy depend on various factors; the suitability of the Ultrasound machine for neonatal cranial work, the use of optimal settings and probes, appropriate scanning protocols, the use of a variety of acoustic windows and last but not the least the scanning experience of the examiner. Knowledge of normal anatomy and the echogenicities of different tissues in normal and pathological situations as well as familiarity with the physiological and pathological processes likely to be encountered are vital. This paper assesses the value and appropriate use, safety and diagnostic accuracy of Ultrasound in evaluating the brain of the preterm born infants. This study group consisted of 308 preterm neonates, the gestational ages at birth ranged from 26 weeks to 34 weeks, and the birth weights ranged from 650 grams to 2250 grams, underwent cranial ultrasound in neonatal intensive care unit (NICU). 31 premature neonates were found to have PVL. Type of delivery, presence of perinatal asphyxia, gestation age and birth weight, were statistically insignificantly associated with PVL. Chorioamnionitis and neonatal sepsis and mechanical ventilation > 72 hours were the statistically significantly factors associated with PVL injury.

Abstract: Objective: the aim of this work is to assess the effect of asthma and its therapy on bone mineral density in children. Patients and methods: thirty asthmatic children and adolescent, their ages ranged from 7-15 years and 15 apparently healthy age and sex matched children were enrolled in the study. All asthmatic patients were on inhaled corticosteroid therapy for at least 6 months duration. Patients and controls were subjected to full history taking, meticulous clinical examination and laboratory investigations; including serum calcium, phosphorus and alkaline phosphatase. Determination of bone minerals density of the lumbar spine by dual energy X-ray absorpiometry (DXA) method at L2 - L4 levels of lumbar vertebrae. Results: showed that height was higher among controls (143.5±12) compared to patients (133.6±11) with statistical significant difference. The study revealed that patients had lower bone mineral density (0.61±0.11) and lower z-score (-2.08±0.5) when compared to control (0.69±0.13) and (-1.4±1.8) respectively with statistically significant difference P<0.05. Conclusion: Bone mineral density was reduced in asthmatic children.

Abstract: Purpose: To study the relationship between (FDG) uptake expressed quantitatively as standardized uptake values (SUVs) in normal breast tissues and breast density, age, menopausal status determined during dual-time point FDG-PET/CT imaging. Materials and Methods: maximum and average SUVs were determined in two hundred eighty four patients (all females; mean age 55.5 ± 14.1 range 13-84 years, 115 premenopausal, 169 postmenopausal) with newly diagnosed unilateral breast cancer, gynecological cancer and lung cancer were analyzed. One hundred forty two (50%) patients had dense breast whereas 142 (50%) patients had non-dense breast according to the ACR Lexicon criteria. All the patients underwent dual time point imaging sequential PET/CT scans for preoperative staging. In the present study, we analyzed maximum and average SUVs for the normal breast parenchyma and nipple regions. Results: Of the 284 normal breast parenchyma; 64.4% showed a decrease and 35.6% showed either no change 20.1% or an increase 15.5% in SUV over time. Similar values for the normal tissue in the nipple region were; 77.5% showed a decrease and 22.5% showed either no change 13% or an increase 9.5% in SUV over time. There was significant difference in maximum and average SUVs of breast parenchyma and nipple in patients with dense and nondense breasts (p < 0.0001). There were trends of negative relationship between physiological FDG uptake and age (p < 0.0001). Furthermore, there was significant difference in maximum and average SUVs of breast parenchyma with different menopausal status (p < 0.0001). Our analysis revealed that breast density, age and menopausal status were significant predictors for FDG uptake in the normal breasts. Conclusion: There was a significant difference in SUVs between the dense and non-dense normal breast. Menopausal status and age do significantly affect the uptake of FDG. Delayed phase imaging can improve the accuracy of the test in the evaluation of breast cancer as the physiological FDG uptake decrease so the pathological uptake becomes prominent and could be easily depicted.

Abstract: The aim of this study is to establish normal values as reference for vertebral end plate from T12 to L4 in normal Sudanese subjects using computerized tomography (CT).130 lateral scout CT scans done using GE Healthcare machine with KV120, MA10-50 for lumber vertebra were obtained from subjects (65 males and 65 females) their ages ranged from (15-74) years old .Endplates angle from T12 to L4 were measured using Cobb Method for both genders and the data were correlated to their ages. For males the endplates mean angles were found to be 7.4±3.5,6.6±3.3,4.7±2.9,5.3±3.8,18.8±7.6 and for females 9.2±4.5,9.9±4.5,9.7±4.2,6.8±4.3,5.9,4.6 for T12,L1,L2,L3and L4 respectively. The research also studied the difference according to gender; it showed significant difference at p value 0.05, the end plates angles were affected as the subjects ages increase. The study concluded that the mean Cobb angle end plate differs significantly from males and females Sudanese subjects and it has relation with age and the values differs from what was mentioned in the previous studies, the knowledge of the normal end plates angle allows better characterization and diagnosis for vertebra from T12 to L4.
