ABSTRACT

Recently, Coronavirus has been given considerable attention from the biomedical community based on the emergence and isolation of a deadly coronavirus infecting human. To understand the behavior of the newly emerging MERS-CoV requires knowledge at different levels (epidemiologic, antigenic, and pathogenic), and this knowledge can be generated from the most related viruses. In this study, we aimed to compare between 3 species of Coronavirus, namely Middle East Respiratory Syndrome (MERS-CoV), Severe Acute Respiratory Syndrome (SARS-CoV), and NeoCoV regarding whole genomes and 6 similar proteins (E, M, N, S, ORF1a, and ORF1ab) using different bioinformatics tools to provide a better understanding of the relationship between the 3 viruses at the nucleotide and amino acids levels. All sequences have been retrieved from National Center for Biotechnology Information (NCBI). Regards to target genomes' phylogenetic analysis showed that MERS and SARS-CoVs were closer to each other compared with NeoCoV, and the last has the longest relative time. We found that all phylogenetic methods in addition to all parameters (physical and chemical properties of amino acids such as the number of amino acid, molecular weight, atomic composition, theoretical pI, and structural formula) indicated that NeoCoV proteins were the most related to MERS-CoV one. All phylogenetic trees (by both maximum-likelihood and neighbor-joining methods) indicated that NeoCoV proteins have less evolutionary changes except for ORF1a by just maximum-likelihood method. Our results indicated high similarity between viral structural proteins which are responsible for viral infectivity; therefore, we expect that NeoCoV sooner may appear in human-related infection.

ABSTRACT

BACKGROUND AND AIM: Health reforms that tend to increase the participation of clients in decision-making requires them to be health-literate; hence, the importance of health education. However, not much research has been done to investigate the differences in health education needs according to demographic characteristics of the clients. The aim of this study was to find out any possible gender differences there may be in health education needs and preferences. SUBJECTS AND METHODS: This cross-sectional study was conducted at Riyadh Military Hospital, Saudi Arabia, on a convenience sample of adult Saudis attending its clinics. Data was collected from April 2009 to May 2010 using a self-administered questionnaire covering demographic data, history and needs of health education, methods, and preferred educator. RESULTS: Of the 1300 forms distributed, 977 were returned completed (75.2% response). Most men (74.0%) and women (77.9%) had had health education, but more women reported that it had been helpful (P = 0.014). More men mentioned health education needs relating to primary prevention (P = 0.027), and unhealthy practices (P = 0.003), and considered the different language a barrier (P = 0.002) even after adjustment for age and education. The one-to-one method was the most preferred health education method for men (72.7%) and women (67.9%). More women preferred group health education (P = 0.02) after adjustment for age and education. Significantly more men preferred pharmacists and dietitians as health educators. CONCLUSION: The results point to a few significant differences between men and women regarding their health education needs, barriers, and preferences. These must be taken into consideration when planning health education programs.

ABSTRACT

An association study of a cohort of 177 Sudanese patients infected with Schistosoma mansoni [82 (46%) males and 95 (54%) females] was conducted to evaluate the factors controlling the regression of liver fibrosis 39 months after treatment with praziquantel using ultrasound evaluation. Periportal fibrosis (PPF) was regressed in 63 (35.6%) patients, while the disease progressed to higher grades in 24 (13.6%) patients. The grade of PPF did not change in 90 (50.8%) patients. The mean values of portal vein diameter, splenic vein diameter and index liver size in subjects in whom PPF regressed after treatment were significantly lower than in subjects in whom the disease was progressed (P<0.0001, P=0.031 and P=0.003, respectively). The progression of hepatic fibrosis in males (15, 8.5%) was greater than that in females (9, 5.1%). Patients with regression or progression phenotypes tend to cluster in certain families. Our study indicated that regression, progression and stabilization of PPF after praziquantel therapy is controlled by gender, age, grade of fibrosis and possibly inherited factors.

ABSTRACT

This is a cross sectional study carried out in Gezira state of central Sudan, an area with a high prevalence of Schistosoma mansoni infection, to determine the prevalence of hepatitis C virus (HCV) antibodies and risks factors for HCV infection. A total of 410 subjects in Um Zukra village were tested for HCV antibodies, 2.2% were reactive. The prevalence was highest in those between 11 and 20 years old with equal prevalence among males and females. No correlation was found between HCV infection and S. mansoni infection or parenteral antischistosomal therapy. It was concluded that HCV infection is of low seroprevalence and that schistosomiasis and parenteral antischistosomal therapy are not major risk factors for infection in the population studied.

ABSTRACT

Ossifying renal tumor of infancy ORTI is a benign neoplasm, which presents with gross hematuria and less frequently as an abdominal mass, histologically it comprises a large cell with an epithelial nature and osteoid formation. We report a case of a 10-month-old girl who developed ORTI as non-opacified upper calyces of left kidney on excretory urography. We outlined the calcific and tumors nature of the lesion by ultrasound and computed tomography. The macroscopic and histological features were pathognomonic.

ABSTRACT

Following the first recorded introduction of the Old World screwworm fly (OWS), Chrysomya bezziana Villeneuve (Diptera: Calliphoridae), into the Mesopotamia valley in Iraq in September 1996, cases of livestock myiasis caused by OWS developed a distinctly seasonal pattern. The annual cycle of clinical OWS cases is explained here on the basis of environmental variables that affect the different life-cycle stages of C. bezziana. This analysis suggests that low temperatures restricted pupal development during the winter, whereas the dispersal of adult flies was constrained by hot/dry summer conditions. A restricted number of OWS foci persisted throughout the year. In these foci, pupal development was fastest during the autumn months. In autumn, rapid multiplication, lasting several OWS generations, allowed subsequent adult fly dispersal across the valley floor during the winter. Hence, the monthly incidence of clinical OWS cases in livestock peaked during December-January and was lowest during July-August. In addition to temperature and humidity, vegetation cover played a role in OWS distribution. Hence the majority of OWS cases were clustered in the medium density type of vegetation [normalized difference vegetation index (NDVI) values of 0.2-0.4] along the main watercourses in the marshy Mesopotamia valley. Although sheep were the host most commonly infested by C. bezziana, local sheep density was not found to be a major factor in disease spread. Satellite imagery and the application of Geographical Information System (GIS) tools were found to be valuable in understanding the distribution of OWS in relation to vegetation and watercourses. The presence of screwworm in Iraq, at the perimeter of the intercontinental OWS distribution, may give rise to major seasonal flare-ups.

ABSTRACT

PURPOSE: To report a case of pure isolated unilateral internuclear ophthalmoplegia from ischemic stroke, and to review its literature. METHODS: A 55-year old man, with a history of long-standing diabetes mellitus, developed acute-onset left internuclear ophthalmoplegia. MRI revealed a small paramedian dorsal pontine infarct ventral and lateral to the aquaductus cerebri. Intracranial MR angiography was normal. A systematic search was performed of the literature from January 1980 to December 2004 by using MEDLINE and EMBASE. Case reports with or series including patients with negative MRI findings were excluded. RESULTS: Nine cases of pure isolated MRI-proven unilateral INO resulting from ischemic stroke including this one, have been reported. In over 75% recovery was reported. CONCLUSION: Isolated unilateral internuclear ophthalmoplegia can be the sole manifestation of ischemic stroke and generally carries a good prognosis.
