Background & Objective: Undiagnosed malarial infectionis associated with significant mortality and morbidity. Laboratory investigations leading to rapid, accurate and timely diagnosis of malaria is still a challenge. This study was done to assess the utility of abnormal White blood cell differential fluorescence (WDF) scattergram for diagnosis of malaria. Our aim was to study the utility of WDF scattergram for early detection of malarial parasite. Methods: All EDTA anti-coagulated blood samples received in laboratory during a period from Dec 2019 to May 2020 were analyzed on anautomated hematology analyzer, Sysmex XN 1000. All abnormal WDF scattergrams pertaining to plasmodium specie were critically evaluated and recorded. Review of Leishman-stained peripheral smears as well as immune-chromatographic assay by rapid test devices (RTD) was done. Accordingly, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for detection of malaria by abnormal scattergram were calculated. Results: Out of total 1, 26,000of samples analyzed, abnormal WDF scattergrams were detected in 96 cases. Amongst these, 95.8% (92) were positive for MP on Leishman-stained peripheral smear as well as on ICT with a p-value of 0.05. WDF scattergram abnormalities typical of malaria showed a sensitivity of 80% and specificity of 93.26%. Positive predictive value of 95.8% whereas negative predictive value of 99.9% was detected. Significant findings of hemolysis, platelet clumps, nucleated RBCS (NRBCs) and RBC agglutination were noted in cases (n=4) with abnormal WDF scattergram negative for malaria on peripheral smear. Conclusion: Interpretation of abnormal WDF scattergram not only increases the early detection rate for malarial parasite but isa strong indicator for presence of hemolysis, RBC agglutination, platelet clumps and leucoerythroblastic blood picture as well. doi: https://doi.org/10.12669/pjms.38.3.4702 How to cite this:Rehan M, Khalid A, Nasreen F.

Objective: The aim of this study was to determine frequency of secondary modifiers in non-transfusion dependent thalassemia. Methods: This descriptive cross sectional study was done at Fauji Foundation Hospital Islamabad. Seventy diagnosed patients of thalassemia intermedia were included. Deoxyribonucleic acid (DNA) was extracted using Chelex method. The Xmn-1 and BCL11A polymorphisms were analyzed by Amplification Refractory Mutation System (ARMS) and Restriction Fragment Length Polymorphism (RFLP) PCR. The PCR amplified products were run on Polyacrylamide Gel Electrophoresis (PAGE). Results: The Xmn-l polymorphism was seen in 26/70 (37.1%) and BCL11A polymorphism was seem in 50/70 (71.4%) of the patients. Conclusion: BCL11A and Xmn-l polymorphisms are important secondary modifiers in patients with thalassaemia intermedia in Northern Punjab. doi: https://doi.org/10.12669/pjms.39.5.7376 How to cite this: Nasreen F, Khalid A, Zafar L, Ahmad S, Shaikh A.

Background: The COVID-19 pandemic forced institutions worldwide to adopt online learning, which opened a new era of challenges. Our research was designed to explore the effect of the pandemic on teaching and learning and identify the solutions to the problems based on participants’ perspectives. Methods: A qualitative study of the phenomenological design was conducted at a medical institute in Pakistan. The participants were selected using the purposive sampling technique. Semi-structured interviews were done which were later audio-recorded, transcribed, and subjected to manual thematic analysis. Credibility was ensured by using multiple data collection sources. Results: The 20 participants selected as interviewees were faculty with more than 5 years teaching experience in the medical institute and had gone through online teaching and learning during COVID-19 pandemic. The thematic analyses of the data generated six themes which were: 1. “I see what you mean”; Re-exploration of educational psychology, 2. Reorganization of curriculum, 3. Mentoring and coaching, 4. Technology: as ubiquities as oxygen, 5. Constructive feedback: a stimulus in pearl formation and 6. Turn the tables: fixing the problem. Conclusion: Online education has emerged as an important mechanism in delivering medical education to undergraduate medical students. Instead of shying away, efforts are needed to restructure the curricula, incorporating various online innovative teaching, and learning tools that are at par with the changing global demands of medical education.
