    Objectives: To investigate the relation between the students' scores in MCQs and MEQs of the summative assessment in pediatrics at the College of medicine KKU. Introduction: Student assessment is the most difficult task in medicine since it is ultimately related to human life and safety. Assessment can take different types of formats with advantages and disadvantages and there is no single prescribed method of choice. Research Methods: This is a quantitative, observational retrospective study enrolling 50 students who completed the final MBBS examination in pediatrics in 2015.The medical students’ scores in MCQs and MEQs in the final MBBS pediatrics examination were collected and SPSS used for analysis. Results: 52% of the students scored A and B, 46% scored C and 2% scored D and nobody scored F. The mean percentage scores in MCQs, MEQs and the combined are75.03%, 79.99% and 76.68% respectively. The standard deviation (SD) for MCQs, MEQs and combined are 0.0753, 0.0763 and 0.0559 respectively.There are no significant differences in means and SD. The correlation (CR) between MCQs and MEQs is -1.73%. The CR between MCQs and MEQs for those who scored A and B is 7.38% which could indicate a weak but significant +ve CR (p value 0.017), (table3). For those who scored C inverse CR (-74.38%) was observed between MCQs and MEQs. Discussion: The main finding of this study was the weakly negative CR between students' performance on MCQs and MEQs. Good performance in MCQs is not necessary correlated with good performance in LEQs. This is not in agreement with Oyebola et al. and Moqattash et al findings, who reported positive CR in the performance of their students. The discrepancy observed in performance between MCQs and MEQs could be explained by the subjectivity and the difficulty in avoiding bias in setting and marking essay questions.   Key Words: multiple choice questions, Modified long essay questions, correlation

    Background: Atrial Fibrillation (AF) increases the risk of stroke by a factor of five, leading a significant cost burdens on healthcare system. Pharmacists, especially those based in a primary care environment are well placed to support patients in this therapeutic area.Objectives: To assess primary care pharmacists’ actual knowledge on the management of AF symptoms and anticoagulation. Furthermore, to investigate the resources used by pharmacists.Methods: A cross-sectional study using survey was conducted, targeting UK-based registered pharmacists employed within primary care settings. Quantitative data were analysed utilising descriptive univariate and bivariate statistics.Results: 349 pharmacists completed the adapted 19-questions of the pharmacists’ knowledge. Out of a maximum of 19 points, the mean score was 14.34 ± 2.2 (75 ± 11.6%). The questionnaire revealed several significant gaps in pharmacists’ knowledge. Most of the surveyed pharmacists (62.8%) reported that they used sources of information to support their consultations. Half reported that they used the National Institute for Health and Care Excellence (NICE) guidance (52.4%) and the British National Formulary (BNF) (50.7%).Conclusions: Primary care pharmacists are knowledgeable about AF and its management; however, some gaps exist which may require addressing. Although pharmacists use a variety of information resources, it is the traditional resources that remain the most frequently used

    AbstractBackgroundSmoking is an independent risk factor for coronary heart diseases and it increases all causes of cardiovascular morbidity and mortality.Aim of the workTo assess the acute effect of cigarette smoking on ventricular diastolic functions (LV and RV) in healthy, young, and slim smokers.MethodsThirty volunteers who had recently commenced smoking (less than one year) and who smoked 1–2 cigarettes per day, underwent ECG, 2D and M-mode echocardiography, standard Doppler echocardiography, pulsed TDI (tissue Doppler imaging) on septal and lateral side of mitral annulus and lateral tricuspid annulus. Vp values were measured. The investigator asked them to hold smoking for at least two days after which echocardiographic examination was conducted before smoking one cigarette and the second examination conducted immediately after smoking one cigarette containing at least 0.4mg of nicotine.ResultsDoppler findings over the mitral valve showed the E wave was significantly reduced from 82.7±10.4 to 74.6±10.4 after smoking; the A wave increased; the E/A ratio was reduced from 1.5±0.3 to 1.2±0.2; the E′ septal significantly decreased (15.3±2.4 vs. 11.2±1.1) after smoking, and the E/E′ ratio increased from 5.5±1.1 to 6.7±1.1. Doppler findings over the tricuspid valve showed the E wave was reduced from 60.6±9.7 to 52.7±9.6; the A wave increased from 42.2±6.5 to 50.1±6.6; and the E/A ratio decreased (1.45±0.25 vs. 1.06±0.19). The E′ significantly decreased from 14.1±1.8 to 10.9±2.4, while the A′ increased (10.2±2.4 vs. 12.7±3.6) after smoking; and the IVRT of the RV was significantly prolonged from 62.9±7.5 to 68.7±7.9 after smoking. The Vp was markedly reduced from 67.8±8 to 55.2±3.5 after smoking. These findings reflected on the LV filling pressure (LVFvp) which increased from 9.8±1.4 to 10.5±1.3 after smoking. All changes were statistically significant at P<0.001.ConclusionsOur study reveals that cigarette smoking can result in significant acute alteration in the diastolic functions of both ventricles

    Purpose: To develop poly-lactic-co-glycolic acid (PLGA) -based nanoparticles (NPs) for the delivery of sunitinib malate (STM) to colon cancer cells.Methods: Three different formulations (F1 – F3) were developed by nano-precipitation technique using various concentrations of PLGA. The NPs were evaluated for particle size, polydispersity index, zeta potential, drug entrapment, and drug loading, using differential scanning calorimetry (DSC), Fouriertransform infrared spectroscopy (FTIR), x-ray diffraction (XRD), and scanning electron microscopy (SEM). Furthermore, in vitro drug release and anticancer studies were carried out on the formulations.Results: Among the three NPs, optimized NP (F3) of STM was chosen for in vitro anti-cancer study against H-29 human colon cancer cells lines based on its particle size (132.9 nm), PDI (0.115), zeta potential (-38.12 mV), entrapment efficiency (52.42 %), drug loading (5.24 %), and drug release (91.26 % in 48 h). A significant anti-cancer activity of the optimized NPs was observed, relative to free STM.Conclusion: These findings suggest that STM-loaded NPs possess significant anti-cancer activity against human colon cancer HT-29 cells lines.Keywords: Sunitinib malate, Poly-lactic-co-glycolic acid, Nanoparticles, Colon cance

    Get PDF
    Primary systemic vasculitis can present with a wide spectrum of manifestations ranging from systemic non-specific features such as fever, malaise, arthralgia, and myalgia to specific organ damage. We describe two cases of cholesterol embolization syndrome and Kaposi sarcoma mimicking primary systemic vasculitis, both of which were characterized by features such as livedo reticularis, blue toe syndrome, a brown, purpuric skin rash, and positive p-ANCA associated with Kaposi sarcoma. Establishing the right diagnosis was&nbsp;challenging, and thus we&nbsp;aim in this study to highlight the possible ways to distinguish them from&nbsp;primary systemic vasculitis.

    BACKGROUND: Recent studies suggest that unhealthy food practices and lack of exercise are the main cause of the progressive increase in the obesity prevalence. AIM: We aim to assess the prevalence of obesity among school students and its relationship to dietary and physical habits. METHODS: A cross-sectional study from 18 intermediate and high schools located in Taif, Saudi Arabia, between April 2014 and June 2015. We excluded any student with a psychological disease or chronic diseases. We calculated the body mass index (BMI) of students by measuring their height and weight. Dietary, physical, sleep habits, and socioeconomic status were assessed. RESULTS: A total of 2943 students participated with a mean age of 15.4 ± 1.7 years. The majority of these were boys and attending government schools with a mean BMI 22.7 ± 8.6 kg/m2. Overall, 13.6% were overweight and 12.8% were obese. One-third of students report a sedentary lifestyle. Compared to girls, boys were more likely to have lower BMI (p &lt; 0.001), be overweight (p &lt; 0.001), exercise for &gt;300 min/week (p &lt; 0.001), own electronic devices other than smartphone (p &lt; 0.001), use the electronic devices &lt;3 h/day (p = 0.007), eat their meals with their family (p &lt; 0.001), eat fruits and vegetables daily (p &lt; 0.05), exercise for &gt;300 min/week (p &lt; 0.001), and walk to and from school at least once weekly (p &lt; 0.001). CONCLUSION: A quarter of the students were either overweight or obese. Girls were more likely to be obese with less favorable socioeconomic, media consumption, dietary, and physical profiles

    CAUSES AND MANAGEMENT OF VIRAL EYE INFECTION

    Introduction: The eye is a fascinating organ for several reasons. It is not only have a composite structure, however it is considered an immune-privileged organ. The anatomy of the eye is composed of the anterior and posterior parts, the line of division is posterior to the lens. The anterior chamber lies within the anterior segment and is an immuneprivileged anatomical location, this is due to the fact that the T-cell response in this area is suppressed This protects the eye from potentially destructive immune attacks however it also makes defence against infectious agents challenging, particularly where T-cell responses are critical for immunological defence. Viruses could get into the eye by direct inoculation, or through haematogenous or neuronal spread. The diagnoses of viral eye infections are usually clinical one, helped by taking a thorough history and performing ophthalmic examination. But in challenging cases the lab tests are essential. In this review, we will discuss the most recent evidence regarding Causes and management of viral eye infection Aim of work: In this review, we will discuss the most recent evidence regarding Causes and management of viral eye infection Methodology: We did a systematic search for Causes and management of viral eye infection using PubMed search engine (http://www.ncbi.nlm.nih.gov/) and Google Scholar search engine (https://scholar.google.com). All relevant studies were retrieved and discussed. We only included full articles. Conclusions: A wide range of of viruses can affect the eye and cause viral eye infections, either as a primary infection or reactivation. Some affect the eye directly while the others indirectly but may still manifest with eye disease. One virus may affect several parts of the eye, while different viruses may cause the same eye disease. This could complicate the clinical diagnosis of viral eye disease, but the lab tests like PCR and antibody tests could assist in challenging cases where there may be diagnostic dilemma. The HIV epidemic has had an huge impact on ophthalmology clinics, this is because the virus can cause different eye diseases, and the associated decrease in cell-mediated immunity makes the person highly susceptible to opportunistic viral eye infections, sometimes with severe morbidity. There could be other viruses that may affect the eye that we did not discuss. Key words: Causes, management, viral eye infection

    Overview on Juvenile Primary Fibromyalgia Syndrome

    Get PDF
    JPFS (juvenile primary fibromyalgia syndrome) is a musculoskeletal pain illness that affects children and adolescents. The intricacy of the clinical picture in JPFS has not been adequately characterized in the literature. JFMS symptoms are sometimes difficult to compare to adult fibromyalgia syndrome since many of them are "medically unexplained" and frequently overlap with other medical disorders.&nbsp; The etiology of the illness is multifaceted, with impaired central pain processing being a significant contributor. Musculoskeletal pain that is severe and pervasive is the defining symptom. Other signs and symptoms include headaches, stiffness, subjective joint swelling, sleep and mood disorders, and headaches. Multiple sensitive spots might be found during a physical examination. The diagnosis has certain criteria and is clinical. Early detection and treatment are crucial. The gold standard of care combines a variety of modalities, but most significantly, exercise and cognitive behavioral therapy. The outlook varies, and symptoms might last well into adulthood. Discussing the epidemiology, etiology, pathophysiology, clinical symptoms, diagnosis, and management of JPFS is the goal of the review

    Greenness assessment of chromatographic methods used for analysis of empagliflozin: a comparative study

    Get PDF
    The analytical chemistry community is attempting to incorporate green chemistry concepts in the development of analytical techniques to redefine analytical methods and dramatically modify the philosophy of analytical technique development. Each greenness assessment method has its own benefits and drawbacks, as well as its own procedures. The results of each greenness assessment method produce numerous deductions regarding the selection of a greenest chromatographic method on which the determination of a greenness assessment tool depends. The current study examined the greenness behavior of 26 reported chromatographic methods in the literature for the evaluation of the medicine empagliflozin using three evaluation methods: the national environmental methods index (NEMI), the eco-scale assessment (ESA), and the green analytical procedure index (GAPI). This comparative study discussed the value of using more than one greenness evaluation methods while evaluating. The findings showed that the NEMI was a less informative and misleading tool. However, the ESA provided reliable numerical assessments out of 100. Despite the GAPI being a complex assessment compared to the others, it provided a fully descriptive three-colored pictogram and a precise assessment. The findings recommended applying more than one greenness assessment tool to evaluate the greenness of methods prior to planning laboratory-based analytical methods to ensure an environment friendly process
