Self-limiting COVID‐19-associated Kikuchi‐Fujimoto disease with heart involvement: case-based review

Background The association between COVID-19 infection and the development of autoimmune diseases is currently unknown, but there are already reports presenting induction of different autoantibodies by SARS-CoV-2 infection. Kikuchi-Fuimoto disease (KFD) as a form of histiocytic necrotizing lymphadenitis of unknown origin. Objective Here we present a rare case of KFD with heart involvement after COVID-19 infection. To our best knowledge only a few cases of COVID-19-associated KFD were published so far. Based on presented case, we summarize the clinical course of KFD and its association with autoimmune diseases, as well we discuss the potential causes of perimyocarditis in this case. Methods We reviewed the literature regarding cases of “Kikuchi-Fujimoto disease (KFD)” and “COVID-19” and then “KFD” and “heart” or “myocarditis” by searching medical journal databases written in English in PubMed and Google Scholar. Results Only two cases of KFD after COVID infection have been described so far. Conclusion SARS-CoV-2 infection can also be a new, potential causative agent of developing KFD.

O papel do exercício físico no tratamento da enxaqueca: qual a evidência?

Objetivo: Determinar a evidência do efeito do exercício aeróbico no controlo das crises de enxaqueca. Fontes de dados: PubMed, National Institute of Health and Care Excellence (NICE), The Cochrane Library, British Medical Journal (BMJ), Canadian Medical Association Infobase e Centre for Reviews and Dissemination. Métodos: Foram pesquisados artigos de revisão sistemática (RS)‌, ‌meta-análise‌s (MA) e normas de orientação clínica (NOC), ‌em‌ ‌português‌‌, inglês e espanhol,‌ ‌sem‌ ‌limite‌ ‌de‌ ‌data‌ ‌de‌ ‌publicação,‌ ‌utilizando‌ ‌os termos MeSH ‌migraine disorders e exercise.‌ ‌Foram‌ ‌também‌ ‌pesquisados‌ ‌estudos originais (EO) ‌publicados‌ ‌nos‌ ‌últimos‌ ‌cinco‌ ‌anos.‌ ‌Incluíram-se‌ ‌os‌ ‌artigos‌ ‌que‌ ‌avaliavam‌ o efeito do exercício aeróbico na frequência, duração e intensidade das crises de enxaqueca. A‌ ‌atribuição‌ ‌do‌ ‌nível‌ ‌de‌ ‌evidência‌ ‌(NE)‌ ‌e‌ ‌força‌ ‌de‌ ‌recomendação‌ ‌(FR)‌ ‌foi‌ ‌realizada‌ ‌com‌ ‌base‌ ‌na‌ ‌escala‌ ‌Strength of Recommendation‌ ‌Taxonomy‌ ‌(SORT),‌ ‌da‌ ‌American‌ ‌Academy of Family‌ ‌Physicians.‌ Resultados: Da pesquisa efetuada obtiveram-se 69 artigos, tendo sido selecionados seis que cumpriam os critérios de inclusão: três RS com MA, uma RS e dois EO. Todos os artigos apresentaram NE 2. A maioria dos estudos incluídos favorece a prática de exercício físico como medida profilática das crises de enxaqueca; contudo, apresentam amostras pequenas, curtos períodos de intervenção e de follow-up e intervenções heterogéneas. Conclusão: Apesar de se considerar necessária a realização de mais ensaios clínicos para definir concretamente os efeitos a curto e longo prazo do exercício aeróbico na enxaqueca conclui-se que é possível recomendar a sua inclusão na abordagem profilática destes doentes (FR B).

Celebrating the 50th Issue of Qatar Medical Journal: Editorial Letter

It is with great pride that we celebrate the 50th issue of Qatar Medical Journal (QMJ) that has achieved significant growth recently. Our mission is to encourage authors to submit high-quality and innovative research promoting medical advancements. In the past two years, manuscripts submissions have tripled in number and were enriched by a more diverse pool of authors with global representation, resulting in an increase in the number of published issues moving from being a biannual to a triannual journal. Additionally, the number of articles published in an issue has doubled. QMJ continues to be an open-access peer-reviewed journal, publishing original research work, reviews, editorials, and case reports that are particularly relevant to medicine and free of charge to authors. It is indexed in several renowned and highly ranked platforms such as PubMed Central, Scopus, Scimago, Google Scholar, and the Directory of Open Access Journals. It was also recently indexed in the World Health Organization's Index Medicus for the Eastern Mediterranean Region (IMEMR). We look forwards to becoming the highest-rated medical journal, in terms of impact factor, regionally.
