الملخص: أهداف البحث: لاختبار ما إذا كان تعلم الأنسجة عن طريق الرسم متفوقًا في بعض الجوانب على التعلم من خلال الرؤية من خلال المجهر فقط. طريقة البحث: تم تقسيم طلاب السنة الثانية في كلية الطب عن طريق أخذ عينات عشوائية بسيطة في المجموعة ''أ'' و ''ب''. كل مجموعة تتألف من 50 طالبا. تم التخطيط لهذه الدراسة ذات الطرق المختلطة في وحدة مدتها ثمانية أسابيع. خلال الأسابيع الأربعة الأولى من الوحدة الدراسية ، تعلم الطلاب في المجموعة ''أ'' علم الأنسجة عن طريق الرسم بينما تعلمت المجموعة ''ب'' من خلال رؤية النص والصور المجهرية. خلال الأسابيع الأربعة التالية، تم تبديل المجموعات بالتصميم المتقاطع. تم تقييم تأثير التعلم عن طريق الرسم بواسطة اختبارالاختيار من متعدد الأول والاختبار الثاني في نهاية أربعة وثمانية أسابيع على التوالي. تم تحليل الدرجات التي تم الحصول عليها في الاختبار الأول والاختبار الثاني عن طريق اختبار t للعينة المستقلة. تم تطبيق اختبار t للعينة الزوجية على الدرجات التي حصل عليها نفس الموضوع عندما يتعلمون بالرسم وبدون إستراتيجية الرسم. من أجل استكشاف تأثير الرسم على تعلم الأنسجة، أجريت دراسة جماعية مركزة. تم اختيار المشاركين الستة بأخذ عينات هادفة. تم تحليل البيانات الخاصة بأسئلة المقابلة شبه المنظمة من خلال تقنيات البحث النوعي للترميز والتصنيف وتوليد الموضوعات. النتائج: أظهر اختبار t للعينة المستقلة أنه لا يوجد فرق ذو دلالة إحصائية في متوسط الدرجات التي حصلت عليها المجموعة ''أ'' والمجموعة ''ب'' في الاختبار الأول والاختبار الثاني. ومع ذلك، كان هناك فرق ذو دلالة إحصائية عندما يتم تعليم علم الأنسجة عن طريق الرسم مقارنة باستراتيجية عدم الرسم، كما هو موضح في اختبار t الزوجي. كشفت دراسة المجموعة المركزة أن الرسم له تأثير إيجابي على الاحتفاظ بالمعرفة وفهم المفاهيم الأساسية للأنسجة لتطبيقها في الأهمية السريرية. الاستنتاجات: يساعد الرسم القائم على التعلم في علم الأنسجة في تطبيق المعرفة الأساسية في السياق السريري. Abstract: Objectives: To determine if learning histology by drawing is superior to learning by looking through a microscope only. Methods: Second year MBBS students were divided by simple random sampling into Groups A and B. Each group comprised 50 students. This mixed-methods study was conducted in an 8-week module. For the first 4 weeks, students in Group A learned histology by drawing, whereas Group B learned by seeing the text and microscopic images. For the last 4 weeks, groups were swapped by crossover design. The impact of learning by drawing was assessed by multiple choice question (MCQ) test I and test II at the end of 4 and 8 weeks, respectively. Statistical analyses of the data were conducted with SPSS version 23. The scores obtained in test I and test II were analyzed by the independent samples t-test. The paired samples t-test was applied to scores obtained by the same subject when they learned with drawing and no drawing strategies. To assess the impact of drawing on learning histology, a focus group study was conducted in six participants selected by purposive sampling. Responses to the semi-structured interview questions were analyzed by qualitative research techniques of coding, categorizing, and generation of themes. Results: The independent samples t-test showed that there was no statistically significant difference in the mean scores obtained by Groups A and B in test I and test II. However, there was a statistically significant difference when the subject learned histology by drawing compared to no drawing, as shown by the paired samples t-test. The results from the focus group study revealed that drawing had a positive impact on knowledge retention and understanding the basic concepts of histology for its application in the clinical context. Conclusion: Drawing-based learning in histology helps with the application of basic knowledge in the clinical context.

Abstract Background This study was carried out to identify and explore the difference in coping strategies for dealing with stress; adopted by medical residents in surgical and nonsurgical specialties. Methods A mixed methods approach, was chosen for this study. In phase one (quantitative); data were collected by a web-based survey, using a structured questionnaire. This survey was carried out in five major teaching hospitals of Rawalpindi & Muzaffarabad in 2020. Purposive sampling was done and data were analysed using SPSS, recording frequencies and major trends. In phase two (qualitative); six focus group discussions were carried out with 24 participants, using semi-structured questions and prompts. Convenient sampling was done from the cohort of phase 1. These focus group discussions, explored the various coping strategies adopted by medical residents. Later, the data were analysed manually for development of codes, sub-themes and themes. Results Out of 250 (100%) participants, 146 (58%) participants responded to the online survey. Surgical residents had a higher response rate (60%, n = 87) than nonsurgical residents. Moreover, female participation (54%, n = 79) was greater than male participation (46%, n = 67). The Mann-Whitney U test was statistically significant only for seeking medical advice to cope with stress (P = .029). There was no statistically significant difference found between the coping strategies, employed by medical residents. In focus group discussions, female involvement was more (58% n = 14) than their counterparts. Four main themes were developed after data analysis: self-regulation, tailor-made strategies, educational focus and support system. Finally, minor differences were obtained qualitatively; like, socializing is preferred by surgical residents whereas, spiritualism is chosen by nonsurgical residents. Conclusion Quantitatively, no significant differences were found between the coping strategies of medical residents, against work-related stress. However, minor differences were obtained qualitatively due to difference in job demands and level of burnout between these two specialities.

Objective: To assess the effect of using a 3-D atlas on academic performance and compare it with the use of power point presentations during online lectures for gross anatomy of the head. Study Design: Comparative prospective study. Place and Duration of Study: Department of Anatomy, Dental College, Heavy Industries Taxila Education City Institute of Medical Sciences, Taxila Pakistan, from Jun to Jul 2020. Methodology: Forty-nine students from first year BDS were selected through nonprobability convenience sampling. They were assigned to two groups, A and B comprising of 25 and 24 students respectively. Group A was taught gross anatomy of head region via Zoom lectures employing a digital three-dimensional anatomy atlas application (Visual body, 2019). Group B was exposed to only two-dimensional pictures through presentations during their lectures. Ten teaching sessions were conducted with post session MCQ based assessments. One comprehensive assessment was conducted at the completion of the region. Results were compared for both groups. Results: The mean scores for three of the post session assessment tests were higher for group A (15.72 ± 2.03, 15.28 ± 2.79, 16.92 ± 2.13) as compared to that of group B (14.64 ± 3.42, 13.66 ± 3.00, 15.04 ± 3.01) (p

Background: The coronavirus disease 2019 (COVID-19) pandemic has transformed the world’s economy, health and education in a blink of an eye. Almost 1 billion learners have been affected across the globe. This has resulted in a paradigm shift to blended learning. Therefore, it was felt necessary to provide practical guidelines for the development of blended curriculum in medical education. It would help to overcome the challenges faced due to unprecedented transformation of medical education on account of pandemic. Methods: Guidelines based on personal experience of the authors and literature search were developed using the complex adapted blended learning system (CALBS) framework. Seven experts developed these guidelines using the nominal group technique. The consent form and literature for CABLS framework was shared with experts. The experts developed the guidelines independently during phase one of the technique. After a given time, phase 2 started with moderator mediated discussion about the individual guidelines developed by the experts. After discussion and mutual consensus four types of guideline ideas were developed. During the third phase the experts ranked the guideline ideas on a scale of 1 to 5. The guideline idea that ranked highest was selected as a final guideline for developing a blended learning curriculum. Results: The group consensus resulted in developing seven guidelines for a blended course or curriculum in medical education. These guidelines are based on a conceptual framework supplemented by expert’s own personal experience and current evidence from literature. Conclusions: These guidelines would provide a comprehensive and systematic approach to develop a blended learning curriculum in medical education.

Behaviourism is the underpinning learning theory of many teaching and assessment tools utilized to enhance the effectiveness of learning. Feedback, reinforcements, motivation, learning outcomes and objectives are few among many which are implied by the medical teachers while teaching both basic and clinical sciences to the students. The claim of Behaviourism being redundant or dead is not based on realities. Behaviourist approach is and will remain the most powerful theory to be implied in educational processes for gaining successful outcomes.

Abstract The accreditation standards developed by WFME are acknowledged as regulatory mechanism for quality assurance of medical education programs. The scoping review aims to collect all the published and unpublished evidence based on the inclusion criteria, to identify the barriers affecting the implementation of quality curriculum defined by WFME. It summarizes and presents the evidence-based challenges faced by middle and low income countries for accreditation process. The literature was searched using search terms, `challenges of WFME accreditation’, `barriers to accreditation’, `challenges to accreditation in health care system’, `hindrances to WFME accreditation standards’, `barriers to WFME standards’, in PubMed, ERIC, PsycINFO databases and Google scholar (for grey literature) to find the evidence published within last 10 years. This search strategy retrieved 922 publications and only 19 articles fulfill the inclusion criteria. A All those studies, which address the barriers or challenges to implementation of accreditation standards in medical education, were included. The inhibitors to implementation of curriculum in course other than medical education were excluded from the study. The included studies address the barriers to nine areas of WFME standards. The data was charted and QualSyst appraisal tool was used to appraise the quality of studies included in review. The eligibility of selected articles was carried out by using the validated QualSyst checklist to assess the quality of included studies. The scoping review will inform and lay the foundation for more empirical studies on quality improvement in health professions education particularly in low and middle-income countries. Keywords: Challenges of accreditation,

The scoping review study was carried out from January 18, 2019, to February 18, 2019, by following the Arksey and O'Malley method of scoping review. An extensive search in the bibliographic databases, PubMed, ERIC, and Google scholar for the gray literature was done. The search was narrowed by a set of inclusion and exclusion criteria. The studies included in the literature search were sort by the PRISMA flow chart. The selected studies address the use of a positive reinforcement strategy to manage disruptive behavior in the classroom. The positive reinforcement strategies identified were praise (41%), feedback (33%), and other classroom management studies (25%). Skinner's operant learning principle has a classroom implication for increasing the likelihood of the desired behavior. The results of the review can be used to implement evidence-based practice and policy regarding improving the desired behavior in the classroom.

Objective: To explore the impact of drawing on students’ understanding of histology. To determine if students who draw images can score better than those who do not. Study design: Quasi experimental. Place and duration of study: Histology Laboratory, Department of Anatomy, Shifa College of Medicine, Shifa Tameer-e-Millat University, from January 2017 to September 2017. Methods: This histological study was carried out during the Endocrinology and reproduction module (ENR) in January, 2017. There students were divided into two groups, A and B of 50 students assigned by random sampling. During the first half of the module Group A drew the microscopic image of the slide in the practical notebook as a normal practice. Group B was shown images only and the task of drawing the images in the practical note book was excluded. At the end of four weeks MCQ paper of 50 questions of higher order thinking to check their concepts of applied histology was given to students. For the next half of the module the groups were flipped over by a cross-over design and Group A only saw the microscopic image and Group B drew the histological image. A second test of MCQs of higher level of application of knowledge was given at the end of four weeks. Results: Analysis of data showed that there is no statistically significant difference between the mean scores obtained by the drawing group and non-drawing group (p>0.05) in both test I and test II. However there is a statistically significant difference in the mean scores of the same group when they draw the microscopic image and when they do not (p

Abstract Background Adaptive designs (ADs) are intended to make clinical trials more flexible, offering efficiency and potentially cost-saving benefits. Despite a large number of statistical methods in the literature on different adaptations to trials, the characteristics, advantages and limitations of such designs remain unfamiliar to large parts of the clinical and research community. This systematic review provides an overview of the use of ADs in published clinical trials (Part I). A follow-up (Part II) will compare the application of AD in trials in adult and pediatric studies, to provide real-world examples and recommendations for the child health community. Methods Published studies from 2010 to April 2020 were searched in the following databases: MEDLINE (Ovid), Embase (Ovid), and International Pharmaceutical Abstracts (Ovid). Clinical trial protocols, reports, and a secondary analyses using AD were included. We excluded trial registrations and interventions other than drugs or vaccines to align with regulatory guidance. Data from the published literature on study characteristics, types of adaptations, statistical analysis, stopping boundaries, logistical challenges, operational considerations and ethical considerations were extracted and summarized herein. Results Out of 23,886 retrieved studies, 317 publications of adaptive trials, 267 (84.2%) trial reports, and 50 (15.8%) study protocols), were included. The most frequent disease was oncology (168/317, 53%). Most trials included only adult participants (265, 83.9%),16 trials (5.4%) were limited to only children and 28 (8.9%) were for both children and adults, 8 trials did not report the ages of the included populations. Some studies reported using more than one adaptation (there were 390 reported adaptations in 317 clinical trial reports). Most trials were early in drug development (phase I, II (276/317, 87%). Dose-finding designs were used in the highest proportion of the included trials (121/317, 38.2 %). Adaptive randomization (53/317, 16.7%), with drop-the-losers (or pick-the-winner) designs specifically reported in 29 trials (9.1%) and seamless phase 2-3 design was reported in 27 trials (8.5%). Continual reassessment methods (60/317, 18.9%) and group sequential design (47/317, 14.8%) were also reported. Approximately two-thirds of trials used frequentist statistical methods (203/309, 64%), while Bayesian methods were reported in 24% (75/309) of included trials. Conclusion This review provides a comprehensive report of methodological features in adaptive clinical trials reported between 2010 and 2020. Adaptation details were not uniformly reported, creating limitations in interpretation and generalizability. Nevertheless, implementation of existing reporting guidelines on ADs and the development of novel educational strategies that address the scientific, operational challenges and ethical considerations can help in the clinical trial community to decide on when and how to implement ADs in clinical trials.

Plant extract-mediated fabrication of metal nanocomposites is used in cell proliferation inhibition and topical wound treatment, demonstrating significant effectiveness. Salvia hispanica L. (chia) seed extract (CE) is used as the reaction medium for the green fabrication of ecofriendly ZnO(CE) nanoparticles (NPs) and Ag/Ag2O(CE) and ZnO/Ag/Ag2O(CE) nanocomposites. The resultant nanoparticles and nanocomposite materials were characterized using UV–visible, Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy-dispersive X-ray (EDX) techniques. In the context of antioxidant studies, ZnO/Ag/Ag2O(CE) exhibited 57% reducing power and 86% 2,2, diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging. All three materials showed strong antibacterial activity against Staphylococcus aureus (S. aureus), Escherichia coli (E.coli), and Bacillus subtilis (B. subtilis) bacterial strains. Additionally, ZnO(CE), Ag/Ag2O(CE), and ZnO/Ag/Ag2O(CE) also revealed 64.47%, 42.56%, and 75.27% in vitro Michigan Cancer Foundation-7 (MCF7) cancer cell line inhibition, respectively, at a concentration of 100 μg/mL. Selectively, the most effective composite material, ZnO/Ag/Ag2O(CE), was used to evaluate in vivo wound healing potential in rat models. The study revealed 96% wound closure in 10 days, which was quite rapid healing compared to wound healing using clinically available ointment. Therefore, in conclusion, the ZnO/Ag/Ag2O(CE) nanocomposite material could be considered for further testing and formulation as a good anticancer and wound healing agent.

Background Success of psychosocial interventions in reducing aggressive challenging behaviour is likely to be related not only to mechanistic aspects but also to therapeutic and system factors. The study aims to examine the facilitators and barriers that influence whether psychosocial interventions for aggressive challenging behaviour in adults with intellectual disabilities lead to positive change. We conducted 42 semi-structured interviews with adults with intellectual disabilities who display aggressive challenging behaviour, family/paid carers, and professionals engaged in or delivering a psychosocial intervention across the UK. Data were analysed thematically using a framework approach. Stakeholders considered therapeutic and supportive relationships and personalised care as facilitating factors in addressing aggressive challenging behaviour. The operational structure of community intellectual disability services and conflicting expectations of professionals and carers were the main contextual barriers that impeded the implementation of psychosocial interventions in adults with intellectual disabilities. Findings highlight the valued components that maximise positive change in adults with intellectual disabilities who display aggressive challenging behaviour. Several operational adjustments including referral criteria, roles of professionals and workforce issues need to be addressed in services to maximise the implementation of psychosocial interventions leading to reduction in aggressive challenging behaviour in this population.

Objective: To evaluate changes in visual acuity and contrast sensitivity in patients with keratoconus after corneal collagen cross-linking. Study Design: Quasi-experimental study. Place and Duration of Study: Armed Forces Institute of Ophthalmology, Rawalpindi, Pakistan, from May 2019 to Apr 2020. Methodology: A total of 48 eyes of 30 patients with progressive keratoconus were included in this study. Baseline uncorrected distance visual acuity, corrected distance visual acuity and contrast sensitivity were recorded, following which transepithelial corneal collagen cross-linking with topical riboflavin and ultraviolet A light was performed. Uncorrected distance visual acuity, corrected distance visual acuity and contrast sensitivity measurements were repeated and recorded 6-months postoperatively. Results: Mean preoperative uncorrected distance visual acuity was 0.56 ± 0.27 logarithm of the minimum angle of resolution which improved to 0.51 ± 0.26 at 6 months after the procedure (p=0.002). Mean corrected distance visual acuity was 0.30 ± 0.19 preoperatively, improving to 0.24 ± 0.18 (p=0.001) at 6 months after corneal collagen cross-linking, thereby depicting a statistically significant improvement. Treated eyes also showed a significant improvement in contrast sensitivity (p=0.001) of 0.05 ± 0.08 logarithmic units of contrast sensitivity, from a mean preoperative contrast sensitivity of 1.72 ± 0.10 to 1.77 ± 0.09 when evaluated 6 months after corneal collagen cross-linking. Conclusion: Corneal collagen cross-linking is a promising advancement in the treatment of keratoconus. It was found effective in significantly improving visual acuity as well as contrast sensitivity, thus enhancing visual outcomes in keratoconus.

Intraocular pressure at insertion right eye in group A and B was 12.04 ± 0.48 and 17.98 ± 0.42 mm of Hg respectively. Intraocular pressure at insertion left eye in group A was 12.12 ± 0.45 whereas in group B was 17.95 ± 0.38mm of Hg (p-value=0.001). Conclusion: I–Gel provides better hemodynamic profile and intraocular pressure stability when compared with endotracheal tube.

Objective: To assess frequency of Hepatitis B and C infection in patients undergoing cataract surgery. Study Design: Cross sectional study. Place and Duration of Study: Armed Forces Institute of Ophthalmology, Rawalpindi, from Jan 2018 to Jan 2020. Methodology: Pre operatively patients were subjected to detail ocular examination for cataract evaluation. Patient under 20 years of age, complicated cataract, uveitis, retinal detachment, previous history of ocular surgery or neurosurgery, treatment with systemic medication causing ocular side effects were excluded from study. Preoperatively hepatitis B and C screening was performed for all enrolled patients. The findings were recorded on data sheets and analyzed through statistical software system (SPSS) version 20. Results: Out of 4671 patients, 35 (0.74%) were positive for hepatitis B surface antigen (HBsAg) and 146 (3.1%) were positive for hepatitis C antibody (HCVAb). Eight (22.8%) females and 27 (77.17%) males were positive for HBsAg. Fifty seven (39.04%) females and 88 (60.96%) males were found to be HCVAb positive. It clearly shows higher prevalence of hepatitis in males. Twenty three (65%) of patient with hepatitis B virus and 80 (54.8%) of patients with hepatitis C virus had nuclear sclerosis cataract as compared to 51% of non-infected patients. Conclusion: Screening of hepatitis B and C is mandatory in order to prevent health care associated hepatitis infection. There has been a role of inflammation due to hepatitis in development of cataract. Further studies may elaborate it vividly.

Objective: To evaluate the sensitivity and specificity of bedside tests for prediction of difficult airway scheduled for ophthalmological surgeries under general anesthesia. Methods: This prospective study was carried out at Armed Forces Institute of Ophthalmology, Rawalpindi, Pakistan from March 2020 to October 2020. All pediatric and adult patients with American society of anesthesiologist grade I to IV undergoing elective ophthalmological surgeries under general anesthesia were consecutively enrolled. Mallampati grading, sternomental, thyromental distance, and mouth opening used as the predictors tools whereas Cormack and Lehane (CL) classification validated with on table laryngoscopy. Grade I and II were assigned as easy laryngoscopy whereas grade III and IV were declared as difficult intubation. Results: Of 232 patients, difficult intubation was observed in 36 (15.5%). Sensitivity and specificity of thyromental distance was 80.5% and 99.4% respectively. Whereas sensitivity of mouth opening was 66.6% and specificity was 99.4%. In case of sternomental distance, sensitivity and specificity corresponded to 61.6% and 100% respectively. The sensitivity and specificity of Modified Mallampati Grading was 97.2% and 96.4% respectively. The relationship between CL grading and MMC showed that all the patients with CL grade I had Malampati grade I, i.e., 28 (100%), while all patients with CL grade IV had Malampati grade IV, i.e., 7 (100%). Conclusion: Bedside tests prove to be useful parameters for prediction of difficult airway at pre-anesthesia assessment among which Mallampati test is most sensitive and specific, subsequently ensuring availability of difficult intubation equipment, which is a focus of concern in third world countries.

The coronavirus infection 2019 (COVID-19) is a progressing viral pandemic. Adverse impacts related to COVID19 are usually includes sore throat, cough, fever and dyspnea. Anosmia emerged as newer reported symptom however, recognition awaited from the World Health Organization (WHO) and Center for Infection Control and Prevention (CDC). This case series features an instance of isolated abrupt presentation of anosmia as a manifestation of COVID-19 between two young males with parallelism of smoking and modest disease manifestation. Loss of smell is demonstrative of COVID-19 disease and has significant ramifications with regards to healthcare workers working close to infected therefore has increased susceptibility.

Objective: To assess knowledge, opinion and perception of the general population regarding corneal donation and transplantation. Another objective was to investigate desires, fulfilment, battle and results of patient’s experiences of Corneal Transplant Surgeries performed at Tertiary Care Eye Hospital. Study type, settings & duration: A Cross-sectional study conducted at Tertiary Care Eye Hospital over a period of twenty one months from July 2018 till April 2020. Methodology: The format of the questionnaire was based on previously published studies in the field of corneal transplantation. Our study was divided into two parts. The first part was conducted via structured questionnaire distributed among the general population (n =2090) visiting our hospital as patients and attendants which assessed basic knowledge regarding corneal transplantation and willingness for donation. Next step was interviews of operated patients of penetrating keratoplasty (n =30). Results: Total 2090 participants responded to questionnaire in our institution with mean age of sample as 36.66±9.00 years. 1693 (81%) had the opinion that corneal donation will help restoring vision of sufferers whereas 300 (14.3%) considered it unethical. 28 (93.3%) of the patients were in good health and prognosis after surgery whereas 2(6.7%) did not have a good outcome. Vision and quality of life of 29 (96.7%) patients’ improved.30 (100%) supported the idea of corneal donation and transplantation. Conclusion: To conclude a noteworthy population can support corneal donation if the government builds up appropriate channels and facilities to promote corneal donation and eye banks.

Background: The introduction of new visual technologies increases the risk of visually induced motion sickness (VIMS). The aim was to evaluate the 6-item Visually Induced Motion Sickness Susceptibility Questionnaire (VIMSSQ; also known as the VIMSSQ-short) and other predictors for individual susceptibility to VIMS.Methods: Healthy participants (10M + 20F), mean age 22.9 (SD 5.0) years, viewed a 360° panoramic city scene projected in the visual equivalent to the situation of rotating about an axis tilted from the vertical. The scene rotated at 0.2 Hz (72° s−1), with a ‘wobble’ produced by superimposed 18° tilt on the rotational axis, with a field of view of 83.5°. Exposure was 10 min or until moderate nausea was reported. Simulator Sickness Questionnaire (SSQ) was the index of VIMS. Predictors/correlates were VIMSSQ, Motion Sickness Susceptibility Questionnaire (MSSQ), migraine (scale), syncope, Social & Work Impact of Dizziness (SWID), sleep quality/disturbance, personality (“Big Five” TIPI), a prior multisensory Stepping-Vection test, and vection during exposure.Results: The VIMSSQ had good scale reliability (Cronbach’s alpha = 0.84) and correlated significantly with the SSQ (r = 0.58). Higher MSSQ, migraine, syncope, and SWID also correlated significantly with SSQ. Other variables had no significant relationships with SSQ. Regression models showed that the VIMSSQ predicted 34% of the individual variation of VIMS, increasing to 56% as MSSQ, migraine, syncope, and SWID were incorporated as additional predictors.Conclusion: The VIMSSQ is a useful adjunct to the MSSQ in predicting VIMS. Other predictors included migraine, syncope, and SWID. No significant relationship was observed between vection and VIMS.

PurposeWe wanted to investigate effects of vitamin D3 (25(OH)D3 and 1.25(OH)2D3) on inflammatory cytokine expression in both activated and non-activated Mφ.Materials and methodsMononuclear cells, isolated from healthy donor buffy coats were cultured for a 6-day differentiation-period. Fully differentiated Mφ were pre-treated with either 25(OH)D3 or 1.25(OH)2D3 for (4, 12 or 24 hours) +/-LPS challenge for 4 hours. Gene expression analyses of VDR, Cyp27b1 and pro-inflammatory markers TNF-α, IL-6, NF-κB, MCP-1, was performed using RT-quantitative PCR. TNF-α protein levels from Mφ culture media were analysed by ELISA.ResultsBoth 25(OH)D3 and 1.25(OH)2D3 significantly inhibited TNF-α expression in both LPS-stimulated and unstimulated Mφ. Also, NF-κB, and to a lesser extend IL-6 and MCP-1 were inhibited. LPS up-regulated Cyp27b1 gene expression which was partly reverted by 1.25(OH)2D3.ConclusionThese data show anti-inflammatory effects of vitamin D3 (25(OH)D3 and 1.25(OH)2D3) in human macrophages, and support, that means for targeting high dose vitamin D3 to the immune system may have beneficial clinical effect in inflammatory conditions.

Objective: To determine the morphological variations and location of pterion in Pakistani male population., Methods: This retrospective observational study was carried out in the Department of Radiology, Shifa International Hospital from December 2018 to June 2019. The sample size was calculated by Open Epi web-based calculator. Fifty-three cranial CT scans with slice thickness of 0.5mm; consecutive scans of males were randomly selected. The patients with no craniofacial fracture and ages from 25 to 45 years were included. The dataset was obtained from Toshiba Aquilion One, 360-slice MDCT. The images were imported into the imaging software PACS (WFM), and analyzed in maximum intensity projection mode with three dimensional multiplanar reconstruction viewers. Measurements were taken in lateral projections of skull in Frankfurt plane, as horizontal and vertical distance from the posterolateral margin of frontozygomatic suture to center of pterion. Vertical distance from the superior border of zygomaticotemporal arch to the center of pterion. The morphological types were also recognized., Results: The type of pterion on right side was 94.3% sphenoparietal 5.6% epipteric whereas left side was (90.5%) sphenoparietal (3.7%) epipteric, (3.7%) stellate type, (1.8%) frontotemporal type. The mean horizontal and vertical frontozygomatic measurements on right side were 2.23 ± 0.22cm and 1.25±0.219 cm respectively. The same measurements on the left side were 2.27-±0.25 cm and 1.226-±0.22 cm respectively. The mean zygomaticotemporal measurements on the right and left sides were 3.45 ±0.29cm and 3.44 ±0.25 cm respectively. The mean distance on right and left side of skull was statistically insignificant., Conclusion: The study provides useful data for position and location of pterion for safe neurosurgical procedures via pterion. Moreover, the knowledge about different morphological types of pterion help the radiologist to differentiate between a fracture line and normal morphological variety., Competing Interests: Conflict of interest: None., (Copyright: © Pakistan Journal of Medical Sciences.)
