Abstract: Background: Liver transplantation (LT) has become the treatment of choice for pediatric and adult patients with end-stage liver disease (ESLD). Objectives: The aim of this study is to know the incidence of arterial complications after living donor liver transplantation and management of these complications and their effect on graft failure and mortality. Patients and Methods: We retrospectively reviewed the early postoperative arterial complications in patients who underwent LDLTx in 2017 and 2018, All patients were admitted, living donor liver transplantations were performed and followed up at the Ain shams university specialized hospital in Cairo, Egypt. Doppler ultrasound and detailed biochemical monitoring of graft function were performed once daily for 7 to 10 days after transplantation. And when indicated after that. Results: the incidence of arterial complications was 7 cases from total 85 cases studied retrospectively (8.2 %). hepatic artery thrombosis in 5 cases (5.9 %) and hepatic artery stenosis in 2 cases (2.4 %) and there is no documented cases complicated by peudo aneurysm or splenic artery steel syndrome. There is graft failure of 8 cases (10.3%) in non complicated group and 2 cases (28.5%) in complicated group, And no graft failure in 70 cases (89.7%) in non complicated group and 5 cases (71.5%) in complicated group. There is mortality of 12 (15.4%) in non complicated group and 4 (57.1%) in complicated group, And no mortality in 66 (84.6%) in non complicated group and 3 (42.9%) in complicated group. Conclusion: Arterial complications are still a major source of morbidity and mortality after OLT. Hepatic artery complications after OLT include hepatic artery thrombosis (HAT), hepatic artery stenosis, hepatic artery pseudoaneurysm (HAP) and splenic artery steel syndrome (SASS). HAS and HAT are the most common hepatic arterial complications, with high rates of morbidity and mortality.

Abstract: Infectious Bursal Disease (IBD), or Gumboro disease, is an acute, highly contagious viral infection of chickens. Infectious Bursal Disease continues to be a potential threat to the poultry industry. Infectious Bursal Disease is a highly contagious, globally occurring acute viral poultry disease caused by a bisegmented, double stranded RNA virus that belongs to the genus Avibirinavirus family Birnaviridae. The disease is economically significant to the commercial poultry industry through the mortality, reduced weight gain and condemnation carcass due to marked haemorrhage in the skeletal muscle as well as immunosuppression. The re-emergence of IBD in variant or highly virulent form in different parts of the world during the last couple of decades, have demanded further research efforts in understanding the added complexity of the disease process and the means to control it. Control of the disease has been through exclusion or eradication of chickens via all-in/all-out procedure and genetic selection of chickens resistant to the disease. At present, the disease is controlled by the combined use of live virus and inactivated oil emulsion vaccines. But these vaccines are not always safe as they may not contain the required immunogens present in the variant strains prevailing in that area. Thus, new technologies and second-generation vaccines including rationally designed recombinant and subunit vaccines have been developed.

Abstract: Background: Ultrasonic measurement of cervix length is the most commonly used method to predict premature birth featured as gradual change, easy to operate, and high sensitivity and specificity. For a long time, new diagnostic methods are tried to predict preterm births. Nicole Sochacki-Wojcicka proposed a new concept anterior uterocervical angle (ACA) referring to the angle between the line of internal cervix and lower segment of anterior uterine wall and the ligature between internal and external cervix. Previous investigations of ACA indicate that it may be a useful parameter to monitor the progression of the cervix towards a labor phenotype. Aim of the work: To evaluate whether uterocervical angle (UCA) can diagnose risk of preterm birth in singletons and to evaluate its performance for diagnosing preterm birth (PTB) in comparison to cervical length (CL). Patients and Methods: This study was conducted on 106 pregnant women at (16-23) attending antenatal care unite or admitted to Obstetrics and Gynecology Department at Al zahraa University Hospital from Dec 2016 to Oct 2018. Age, last menstrual period, week of gestation, gravida, parity, abortion, preterm labor history, previous cervical surgery, body mass index, and presence of chronic disease, were investigated, their Bishop scores were calculated, and cervical length and UCA measurements were performed by transvaginal ultrasound examination under optimal conditions. The patients were discharged after observation, examination and treatment processes. After the delivery, the week of gestation, delivery type, newborn’s birth weight, sex and the need for intensive care unit were investigated. The pregnant women were divided into preterm group and mature group according to the pregnancy outcomes. Results: A total of 106 women were studied. The rate of PTB in this cohort was 33.1% for delivery <37 weeks and 66.9 for<37 weeks. ROC curve of UCA and CL was conducted for discrimination between term and preterm labor (at 37 weeks). Fair AUC for UCA was found (AUC = 0.716, p<0.001). At cut off value of 94.95, sensitivity was 51.4%, specificity was 94.4%, PPV was 81.8%, NPV was 79.8% and accuracy was 80.2%. Poor AUC for CL was found (AUC = 0.614, p=0.018). At cut off value of 3.85, sensitivity was 71.4%, specificity was 59.2%, PPV was 46.38%, NPV was 80.8% and accuracy was 63.2%. UCA was considered to be significantly better than CL for discrimination between term and preterm labor (at 37weeks) (p=0.048). Regression analysis revealed a significant association of BMI at delivery, prior preterm delivery, prior D & C, Incidence of CS and NICU admission with PTB and UCA. There was no correlation identified between maternal age, parity, natural conception and obesity at delivery on sPTB and UCA. Conclusion: The UCA is an objec­tive and effective indicator to predict preterm birth in the second trimester measured by transvaginal ultrasound. The diagnostic value of measuring the UCA was better than that of measuring the cervical length in the same period.

Abstract: Objective: This study aims to assess the role of multi detector computed tomography in the evaluation of trauma to the chest including both bony and soft tissue injuries and comparing them with the radiographs. Methods: It was a prospective study carried out at Alzahraa university hospital. A total number of25 patients coming to the emergency department with history of chest trauma from January 2019 to June 2019 were selected and examined clinically. Those who had findings that suspect chest trauma on clinical examination underwent CXR and 160 slice MDCT examination. Finally, we compared between CXR and MDCT in detection of complications of blunt chest trauma. Results: MDCT has been shown to be better than chest X-ray in assessment of complications of chest trauma especially as concerns the vertebral fractures, hemothorax, hemopneumothorax, pulmonary contusions and mediastinal injuries. Conclusion: Whereas chest radiographs are broadly used as the first imaging modality in suspected chest trauma in the emergency settings, a subsequent computed tomographic evaluation has proven to be more effective, especially with the advance in its multiplanar capability, since it’s more sensitive than chest radiographs in detecting chest injuries, especially pulmonary and mediastinal ones. The early use of MDCT in chest trauma cases allows early detection of possible serious injuries and better evaluation of the underlying pathology which in turn allows for better and proper management of the case that subsequently decreases the risk of complications and decreases trauma related morbidity and mortality rates.

Abstract: Background: Primary hyperparathyroidism emerged from relative obscurity before the 1970s to become the third most common endocrine disorder in more recent times. Pathological correlates in primary hyperparathyroidism include parathyroid adenoma (80-85%) and hyperplasia (10-15%) and malignancy, which can occur in <1-5% of patients. In the past, both benign and malignant parathyroid disease would present symptomatically in affected patients. However, with the advance of routine serum calcium testing, the majority of patients with benign hyperparathyroidism are now diagnosed incidentally and asymptomatically. In addition to clinical and biochemical information, certain radiological features can help to distinguish benign from malignant parathyroid disease in the preoperative setting in all patients with primary hyperparathyroidism, radiological investigations is warranted to assess the extent of disease for treatment planning. Patients with primary hyperparathyroidism and symptoms or signs should undergo surgi­cal removal of their parathyroid gland (s). Aim of the Work: The aim of this essay is to review the management of parathyroid glands tumours and the most recent updates in the parathyroid glands surgeries. Conclusion: Parathyroid surgery has evolved from conventional open parathyroidectomy, with exploration of all four parathyroid glands, to minimal access open or endoscopic parathyroidectomy. This evolution was made possible by the development of high resolution radiological techniques and the development of the rapid IOPTH assay. Sonography and technetium-99m-sestamibi (99mTc-sestamibi) scintigraphy are the most commonly used imaging techniques for the demonstration of parathyroid lesions. Neck ultrasonography is a non-invasive and relatively inexpensive tool that should be considered in all patients with overt hyperparathyroidism. The recent development and adoption of 99technetium-labelled sestamibi (99mTc-sestamibi) scintigraphy has enhanced our ability to distinguish between single-gland and multigland parathyroid disease. Although not routine, CT scan of the neck and chest may also be indicated in some cases to assess for disseminated disease. Recently, some investigators described a promising method by which a 3rd-generation to 2nd-generation PTH ratio >1 can help predict whether a parathyroid tumor is more likely to be malignant in the preoperative setting (sensitivity: ~75-82%; specificity: ~97-98%).. Rapid intraoperative assay is extremely helpful in confirming the complete removal of abnormal “hyperfunctioning” parathyroid tissue (demonstrated by >50% decrease in circulating PTH level 10-15 min after surgical excision), and can help distinguish between single-gland and multi-gland disease. Patients with primary hyperparathyroidism and symptoms or signs should undergo surgi­cal removal of their parathyroid gland (s). However. In some patients, with medical comorbidities may preclude surgery, controlling hypercalcemia alone may be the goal.

Abstract: - Across-sectional study was carried out in Bambasi, Homosha and Kurumuk Districts of Benishangul Gumuz Regional State, Western Ethiopia from September to January, 2018 to determine bovine trypanosomosis prevalence, prevailing trypanosomes species, vector density and associated risks. Blood samples collected from (n=340) randomly sampled cattle (Bos indicus). Dark phase contrast buffy coat procedures were used for determining prevalence. Whereas, haematocrit method was used for packed cell volume (PCV) values determination. Furthermore, traps were deployed for the purpose of entomological survey. Out of total 340 samples, 18/340 (5.29 %) were found trypanosome positive. Based on Predominant trypanosome species among recorded were Trypanosome congolense 14/18(77.7%) and Trypanosome vivax 4/18 (22.2 %). There were statistically significant differences concerning existing trypanosome species (P< 0.05). Mean packed cell volume (PCV) value of the parasitic animals was lower (21.06 % + 0.03 SE) than aparasitic animals (28.99% +0.012) and the variation was not statistically significant (P>0.05). Sex groups, age categories and study sites (P> 0.05) were not demonstrated significant risk factors, however body conditions was found significant (p< 0.05). During the survey, Glossina moristans submorsitans was found in the area (1.39 f/t/d) along with other mechanical vectors such as stomoxys (7.37f/t/d), haematopota (0.018 f/t/d) and tabanus (0.064 f/t/d). In conclusion, the current study showed moderate trypanosomosis prevalence in the area reflecting the need for strategic control measures.

Abstract: Bluetongue is an infectious and non-contagious arthropod borne viral disease of domestic and wild ruminants, it is usually considered to be a disease of improved breeds of sheep, specially the fine-wool and mutton breeds. The disease derives its name from its mechanism of action to produce the disease that results in cyanotic or bluetongue. The disease was first described in the Cape Colony of southern Africa but now the virus has now been isolated on all continents except Antarctica. The distribution and intensity of BTV infection in regions of the continents is determined by climate, geography and altitude, presence Culicoides vectors and susceptible mammalian hosts. Recently, the global distribution and nature of BTV infection has changed significantly and climate change has been considered as a potential cause of this dramatic event observed globally. In line with global change in the distribution and infection of BTV, seo-prevalence studies made in different parts of Ethiopia showed the presence of circulating antibodies of BTV in each agro-ecological zone. Although there were no reported clinical case of BT in the country, results of a few studies made on the disease showed a trend of increasing sero-prevalence of circulating antibodies. The increase in seroprevalence of circulating antibodies may result in severe infection and high mortality if susceptible animals to the disease are introduced into or exposed to circulating antibodies. Sero-prevalence studies that were carried out regarding the disease in the country focused only on small ruminants and did not consider the situation in other host animals susceptible to the disease, the distribution and species of vectors responsible for the transmission of the disease and serotype (s) of the virus responsible for circulating antibodies were not determined. Moreover, studies made on the epidemiology of BT did not include all agro-ecological zones in all regions of the country. In general to fill the gaps of information in the disease epidemiology in Ethiopia, surveillance system and studies made on BTV infection should be extended so as to include other susceptible ruminant hosts and to study the distribution of insect vectors and should take in to account each agro-ecological zones of the country to better predict the situation of the disease in the future.

Abstract: Back Ground: Assessment of functional vascular impairment is usually performed by using noninvasive vascular function tests. Impairment of vascular function is highly concomitant with the progress and maintenance of atherosclerotic conditions, ending with injury in the target organ. The introduction of ultrasounds as non-intensive technique for diagnosis of some disordered such as vascular diseases is important for measurement of conduit artery dilation consequent to post ischemic hyperemia, an arterial shear stress stimulus and assessment of temporary suprasystolic cuff inflation around the limbs. Ultrasounds (USs) is widely applicable in many scientific and medicinal fields due to its noninvasive nature and simplicity, therefore it is known as flow mediated dilation (FMD) approach. Methods: This was a case-control study. The study took place in intensive care unit (ICU) of the Faculty of medicine Cairo University. FMD of the brachial artery by B-mode SIEMENS ACUSON X300 ultrasonography was assessed. FMD was calculated with the formula: FMD = [ (DF –Di)\ DI] x 100. Results: FMD of the brachial artery was significantly low (7.31% ± 0.75%) in patients with AKI compared to (11.67 % ± 1.26%) in control group which showed statistical significance (P<0.001). Conclusion: From this study, our present observations indicate that AKI is associated with endothelial dysfunction with significant lowering in the flow mediated dilatation of the Brachial artery case group.

Abstract: This study presents to identify the key determinants influencing users’ satisfaction of bus transit in the city of Kerman, Iran. It is essential to consider the customer’s point of view which is relevant for evaluating the performance of a transit service. Factor analysis is used to examine 29 attributes delivering by service contributors. The factors were judged by the public transport users in the main bus Terminals in Kerman to obtain a deeper understanding of their opinion and concerns which are vital in making the bus transit services more organized. Findings of this study revealed that accessibility is the priority of users’ satisfaction followed by five other significant factors including comfort, time, reliability, safety and cost for the users’ satisfaction from operating and performance of public transport services. The Kerman Bus Organization (KBO) policy makers may use corrective actions in their strategic plans that can better cater the public transport users.
