Diagnostic challenge of intestinal obstruction secondary to Henoch–Schonlein purpura

Henoch–Schonlein purpura is the most common form of vasculitis in pediatric age group. Gastrointestinal manifestations have been long recognized as part of the disease, but usually preceded by other manifestations. We present a case of a boy whose initial manifestation of the disease was bowel obstruction and ischemia requiring surgical intervention twice with diagnostic dilemma prior to diagnosis of Henoch–Schonlein purpura. Although common surgical diseases prove to be the culprit in most cases, a surgeon should always keep an open mind for possibility beyond surgical diseases. Multidisciplinary approach to situations where ambiguities in diagnosis exist proves to be a valuable tool aiding surgical decision.Keywords: gastrointestinal, henochscholine, intestinal ischemia, intussusception, purpur

Perception of Faculty Members of Regional Medical School Toward Faculty Development Program

Introduction: Any types or process of activities that are performed by a group or an individual to enhance, promote, and improve the performance, competencies or skills of a health professional at an institute level are defined as faculty development which has many other names like staff development, academic development, and educational development. The importance of faculty development stressed by Harden is equivalent to curriculum development, which is a very difficult assignment. Objectives: To determine the pattern of faculty members’ perception toward their weekly faculty development program. Methodology: Enrolling the faculty members of the College of Medicine, University of Bisha, Kingdom of Saudi Arabia ( COM/UB,KSA). COM/UB adopting the innovative curriculum (problem-based learning, team-based learning, interactive lectures, and case-based learning and seminars. Each Tuesday, faculty members gather in the faculty development academic program (FDAP) room to discuss issues related to medical education and quality. Usually, there is a presentation on the selected topic over 25 min, followed by a discussion and workshop, and finally, a recommendation is drawn. The inclusion criterion is those staying in the college for a period of more than one year. New joiners and those staying for a period of less than one year were excluded. Faculty members were enrolled optionally and requested to fill a validated questionnaire. Results: The response rate was 92% of total staff. More than 89%, 87%, 86% and 74% thought that the FDAP is useful to them, helps them in addressing academic issues in the faculty, is an enriching experience, and thought that it helps them in constructing high-quality multiple choice questions (MCQs). Finally, 84% were interested in presenting topics in FDP. Conclusion: FDAP was positively perceived by the faculty members of the University Bisha/College of Medicine, since it enriches their experience and satisfies their academic job.

Isolation and Genetic Characterization of Rift Valley fever virus from Aedes vexans arabiensis, Kingdom of Saudi Arabia

An outbreak of Rift Valley fever in the Kingdom of Saudi Arabia and Yemen in 2000 was the first recognized occurrence of the illness outside of Africa and Madagascar. An assessment of potential mosquito vectors in the region yielded an isolate from Aedes vexans arabiensis, most closely related to strains from Madagascar (1991) and Kenya (1997)

Overview on Epidemiology and Management of Myxedema Coma or Crisis

The most severe type of hypothyroidism is known as myxedema coma, which can quickly lead to death if not identified and treated aggressively. The condition known as hypothyroidism is easily detected and treated. But if ignored, it might eventually progress to myxedema coma, the most serious form of hypothyroidism. Since the majority of patients do not initially appear in a coma, the term "myxedema coma" is usually regarded as misleading. Lethargy usually progresses to stupor, which then becomes a coma with hypothermia and respiratory failure. only clinical criteria are used for diagnosis because thyroid hormone assays are unable to distinguish between simple hyperthyroidism and thyroid storm. Apart from essential medical interventions, the treatment focuses on preventing thyroid hormone production and secretion as antithyroid medications, and preventing the peripheral effects of thyroid hormone as β-blocker, glucocorticoids. The diagnosis of thyroid-stimulating hormone (TSH) in the blood is the same as that of simple hypothyroidism. As soon as a diagnosis is obtained, treatment should start right away. The majority of hospital and commercial laboratories can turnaround a TSH test in a matter of hours

Access and utilisation of primary health care services comparing urban and rural areas of Riyadh Providence, Kingdom of Saudi Arabia

The Kingdom of Saudi Arabia (KSA) has seen an increase in chronic diseases. International evidence suggests that early intervention is the best approach to reduce the burden of chronic disease. However, the limited research available suggests that health care access remains unequal, with rural populations having the poorest access to and utilisation of primary health care centres and, consequently, the poorest health outcomes. This study aimed to examine the factors influencing the access to and utilisation of primary health care centres in urban and rural areas of Riyadh province of the KSA

Template free synthesis of graphitic carbon nitride nanotubes mediated by lanthanum (La/g-CNT) for selective photocatalytic CO2 reduction via dry reforming of methane (DRM) to fuels

Template-free fabrication of graphitic carbon nitride nanotubes modified with lanthanum (La/g-CNT) for dynamic photo-catalytic CO2 reduction with CH4 has been investigated. Successful fabrication of g-C3N4 nanosheets and nanotubes were obtained with enhanced photo-activity under visible-light. Using 5 wt% La/g-CNT, CO yield of 491 mu mole g-cat(-1) h(-1) was obtained which is 3.6 and 5.9 folds higher than g-CNS and g-CN samples. Similarly, production of H-2 was highest over La/g-CNT which was 2.95 folds more than g-CNT and 5.1 times higher than using g-CN. Although, pristine g-CN has more basic sites and larger BET surface area but enhanced photo-activity over La/g-CNT can be attributed to efficient transfer of electrons over 1D structure and separation of charge carriers by La. More interestingly, effect of CH4/CO2 feed ratios was obvious, whereas, highest CO was produced at CH4/CO2 ratio of 1.0 but H-2 was maximum with ratio of 2.0. Among the different reaction systems, highest CO was obtained using DRM, while CO2 reduction by H-2/H2O promoted both CO and CH4 production. This was obviously due to basic characteristics, sorption competition over the catalyst surface and favorable reverse water gas shift (RWSG) reaction. The stability test further confirmed the suitability of this material which prevailed until three cycles without obvious deactivation. This work will open new opportunities to develop structured nanocalaysts for solar energy based reutilization of CO2 and CH4 for the production of renewable fuels

Machine Learning-Enabled Smart Industrial Automation Systems Using Internet of Things

Industrial automation uses robotics and software to operate equipment and procedures across industries. Many applications integrate IoT, machine learning, and other technologies to provide smart features that improve the user experience. The use of such technology offers businesses and people tremendous assistance in successfully achieving commercial and noncommercial requirements. Organizations are expected to automate industrial processes owing to the significant risk management and inefficiency of conventional processes. Hence, we developed an elaborative stepwise stacked artificial neural network (ESSANN) algorithm to greatly improve automation industries in controlling and monitoring the industrial environment. Initially, an industrial dataset provided by KLEEMANN Greece was used. The collected data were then preprocessed. Principal component analysis (PCA) was used to extract features, and feature selection was based on least absolute shrinkage and selection operator (LASSO). Subsequently, the ESSANN approach is proposed to improve automation industries. The performance of the proposed algorithm was also examined and compared with that of existing algorithms. The key factors compared with existing technologies are delay, network bandwidth, scalability, computation time, packet loss, operational cost, accuracy, precision, recall, and mean absolute error (MAE). Compared to traditional algorithms for industrial automation, our proposed techniques achieved high results, such as a delay of approximately 52%, network bandwidth accomplished at 97%, scalability attained at 96%, computation time acquired at 59 s, packet loss achieved at a minimum level of approximately 53%, an operational cost of approximately 59%, accuracy of 98%, precision of 98.95%, recall of 95.02%, and MAE of 80%. By analyzing the results, it can be seen that the proposed system was effectively implemented

Body Mass Index and <i>Helicobacter pylori</i> among Obese and Non-Obese Patients in Najran, Saudi Arabia: A Case-Control Study

Objective: We examine obese and non-obese patients with respect to Helicobacter pylori (H. pylori) positive-infection (HPPI) and associated factors, specifically body mass index (BMI). Methods: This study took place in the Department of Endoscopy of a central hospital in the Najran region of Saudi Arabia (SA). A total of 340 obese Saudi patients (BMI &#8805; 30 kg/m2) who had undergone diagnostic upper endoscopy before sleeve gastrectomy, were compared with 340 age and gender-matched control patients (BMI &lt; 30 kg/m2) who had undergone diagnostic upper endoscopy for other reasons. Data collected included diagnosis of HPPI. Descriptive and multivariable binary logistic regression was conducted. Results: Mean patient age was 31.22 &#177; 8.10 years, and 65% were males. The total prevalence of HPPI was 58% (95% CI = 54&#8315;61%) with obese patients presenting significantly more HPPI than non-obese patients (66% vs. 50%, OR = 1.98, 95% CI = 1.45&#8315;2.70, p &lt; 0.0005). Age and gender did not associate significantly with HPPI (p = 0.659, 0.200, respectively) and increases in BMI associated significantly with increases in HPPI (p &lt; 0.0005). BMI remained a significant factor in HPPI when modelled with both age and gender (OR = 1.022, 95% CI = 1.01&#8315;1.03, p &lt; 0.0005). Conclusions: Within the limitations of this study, the significance of HPPI in obese Saudi patients residing in the Najran region in SA was demonstrated alongside the significance role of BMI in HPPI
