It is the most commonly known and prevalent type of peripheral entrapment neuropathy that accounts for about 90% of all entrapment neuropathies. This review aims to provide an outline of CTS by considering anat-omy, pathophysiology, clinical manifestation, diagnostic modalities and management of this common condition, with an emphasis on the diagnostic imaging evaluation.展开更多

Chronic use of analgesics and anti-inflammatory medications for pain management may improve symptoms but on long term may affect HRQoL negatively. The objective of the present study was to compare the impact of two different classes of analgesics, traditional non-steroidal anti-inflammatory drugs (NSAIDs) and selective cyclo-oxygenase-2 (COX-2) inhibitors on HRQoL among osteoarthritis patients using the SF-36 questionnaire. Methods: Clinic based cross-sectional study conducted at Al-Qassimi Hospital, Sharjah, United Arab Emirates (UAE), over a period of six months. Ethical Approval was obtained from the ethics committee at Al-Qassimi Clinical Research Center. Total of 200 osteoarthritis patients fulfilling the inclusion and exclusion criteria were involved in the study. Patients’ demographics were collected from their medical records. The Medical Outcome Study Short-Form 36 (SF-36) questionnaire was used to measure patients’ HRQoL. SF-36 data were scored using health outcomes scoring software 4.5. Results: Mean age of the subjects was 62.19 ± 9.81 years with females constituting 151 (75.5%) of the patients. In general, females scored lower in most of the HRQoL domains compared to males and there was significant difference between the two groups in the mental health (p = 0.005) & mental component (p = 0.042) domains. Compared to selective COX-2 inhibitors, patients on NSAIDs scored higher on all domains of SF-36 except physical functioning. There was significant difference in mental health domain for patients treated with NSAIDs (p = 0.02). Celecoxib was only better than NSAIDs in osteoarthritis patients with more than one musculoskeletal disorders in the domain of bodily pain (p = 0.009). Conclusion: NSAIDs-treated patients did not differ significantly from celecoxib-treated patients in all domains of the SF-36 except for the mental health domain.展开更多

Antibiotics are necessary only in case of secondary infection, but overlapping with bacterial infection mainly occurs after hospitalization, and the vast majority of infections were caused by the Acinetobacter baumannii strain. Commonly used antimicrobial disinfectants are chlorhexidine derivatives;due to their frequent use, microorganisms have become resistant to them, and in addition, chloroquine has no clinical benefit in the treatment of COVID-19. Virus escapes from the immune response due to multiple mutations in the receptor-binding domain, or the N-terminal end, which are the sites responsible for antibody binding and virus neutralization. The COVID infection itself is characterized by a rather powerful suppression of immunity. For this reason, the use of antibiotics in the absence of a secondary infection layer leads to greater suppression of the immune system and an aggravation of the process, which often ends up fatally. Immune dysregulation predisposes to the development of severe COVID-19. A decrease in the number of leukocytes gives an unfavorable prognosis for the severity of the COVID infection course. The main reason for the death cases after vaccination seems to be an increase in blood clotting, which is observed not only among the population over 60 years old, but also amid young people.展开更多

Various applications of ad hoc networks have been reported in the literatures including disaster management, battle field, environmental management, healthcare, and smart grid. Ad hoc networks have some limitations namely short operating life, unreliability, scalability, delay, high interference, and scarce resources. In order to overcome these limitations, numerous researches have been carried out. Smart antenna integration is one of them. It has been shown in the literatures that smart antenna can improve network’s capacity, increase network lifetime, reduce delay, and improve scalability by directing antenna radiation pattern in a desired direction. But, producing a desired antenna radiation pattern is not a simple task for resource constraint ad hoc networks. A careful selection of beam forming algorithm is required. In this paper we show that smart antenna system, consisting of circular microstrip antennas and arranged in a linear arrangement, is the most suitable choice for ad hoc network. We compare a number of smart antenna algorithms in this paper under different noisy conditions. We show that the Least Square Constant Modulus (LSCM) and Least Constant Modulus (LCM) algorithms outperform other algorithms in terms of directivity and minimized side lobes.展开更多

Self-medication patterns vary among different populations and are influenced by many factors. The objective was to investigate the nature of self-medication behavior among the general public in the UAE and to explore public attitudes, beliefs, and level of knowledge concerning self-medication. Methods: A purposive sample of individuals involved in self-medication who belong to different age, gender, income, education level and health-seeking behaviors. A qualitative approach through individual face-to-face interviews was utilized to investigate participants’ behaviors and attitudes towards self-medication;factors influencing decision to self medicate, sources of information on medications, types of conditions for which self-medication is sought and types of medications used. Participant recruitment continued until theme saturation using content analysis. Findings: Three themes emerged from the data: Reasons for self-medication such as costs associated with visiting a doctor, convenience in visiting a pharmacy and perception of simplicity of the condition;Sources of information: pharmacists as a main source in addition to medication leaflets, family role and previous use, and medicines and medicines’ use: medicines’ use in chronic disease, use of antibiotics, use of herbals and supplements and medicines’ use in children. Conclusion: Findings from this study indicate that self-medication behaviors are common among the population due to several reasons. Inappropriate self-medication practices are evident and may compromise patient care outcomes. Pharmacists play a vital role in intervening to optimize the use of medications and patient education regarding self-care.展开更多
