Background:Chronic autoimmune urticaria (CAU) is one of the most challenging therapeutic problems faced by a dermatologist. Recently, weekly autologous serum injections have been shown to induce a prolonged remission in this disease.Aim:To evaluate the efficacy of repeated autologous serum injections in patients with CAU.Materials and Methods:Seventy patients of CAU were prospectively analyzed for the efficacy of nine consecutive weekly autologous serum injections with a post-intervention follow-up of 12 weeks. Total urticaria severity score (TSS) was monitored at the baseline, at the end of treatment and lastly at the end of 12 weeks of follow up. Response to treatment was judged by the percentage reduction in baseline TSS at the end of treatment and again at the end of 12 weeks-follow-up.Results:Out of the 70 patients enrolled, 11 dropped out of the injection treatment after one or the first few doses only. Among the rest of 59 patients, only 7 patients (12%) went into a partial or complete remission and remained so over the follow-up period of 12 weeks. Forty patients (68%) did not demonstrate any significant reduction in TSS at the end of the treatment period. Rest of the 12 patients showed either a good or excellent response while on weekly injection treatment, but all of them relapsed over the follow-up period of 12 weeks.Conclusion:Autologous serum therapy does not seem to lead to any prolonged remission in patients of CAU.

Objectives: To explore the perception of postgraduate public health students regarding e-learning in context to Covid-19 pandemic and its effect on their academic performances Methods: This cross-sectional study was conducted at Sarhad Institute of Health Science, SUIT Peshawar from 3rd October 2020 to 4th February 2021. The Census method was incorporated for sample selection. Participation in the study was subjected to consent by participants. A self-administered questionnaire was used for data collection. Data was analyzed using SPSS Version-26. Results: Out of 95 participants, 72 (75.8%) were males and 23 (24.2%) were females. The mean grade point average (GPA) of previous semester-1 and semester-2, when they were having a conventional education system on campus before the pandemic was 2.741±0.499 and 2.643±.498 respectively. The current mean GPA of semesters 1, 2, and 3 who had online classes during this pandemic was 2.41±0.66, 3.06±0.51, and 2.80±0.47 respectively. Fifty-one (53.7%) students preferred to use mobile for e-learning. Convenience to the use-learning management system (LMS) was 67.4% and 72.6% responded that their academic performance was positively affected by e-learning. Logistic regression revealed that source of learning (p 0.99), uninterrupted internet (p 0.87), convenience with LMS (p 0.17), stress (p 0.505), convenient communication with faculty (p 0.69), and compatibility with professional routine (p 0.21) were not significantly associated with good academic performance, however, students of semester 2 (p 0.001) and those using laptops (p 0.02) were more likely to get a GPA of 3.0 or above Conclusions: Students in this study had a positive perception regarding e-learning however, there is a definite need to amalgamate both online and on-campus learning modalities for post-graduate students especially during the uncertain situations. doi: https://doi.org/10.12669/pjms.38.3.4626 How to cite this:Aleem S, Mahsood N, Kibria Z, Gul R.

Objective: To assess the oral health status of 10-15-year-old children enrolled in government schools. Materials and Methods: This cross-sectional study was conducted over a period of 11 months from March 2020 till Feb 2021 among children aged 10-15 years going to government schools in Kheshgi Payan District Nowshera KPK. Multi stage sampling technique was incorporated. Children of age 10 -15 years were included and those above or below this age group were excluded from study. Pre-Validated WHO oral health assessment tool was used for this study. Data was analyzed using SPSS Version 24. Results: Data from 200 students 100 each from girls’ and boys’ schools was collected. Majority of students 21% (n=42) were of 12 years of age. The mean age was 12.58 ±1.64. A total of 59% children had sound dentition. Caries was present in (n=44) male and (n=29) female children. There was a significant association between the gender and the dentition of the children (p 0.005). Gingivitis and periodontitis were prevalent in 20% of the study participants. Conclusion: This study concludes significant association between gender and dentition of the children. Over all the oral hygiene of the children was found to be satisfactory.
