The prognosis of encephalitis is difficult and almost all the patients seem to be at a high risk of poor outcomes. A number of physiological changes take place during encephalitis and have been evaluated for their prognostic value. Platelet count, which has been recognized as a surrogate prognostic marker in various viral illnesses, has recently been recognized to have a prognostic value in AE too. In the present study, we attempted to study the role of thrombocytopenia in the prognosis of AE.</p><p><strong>Methods: </strong>Total of 98 cases based on clinical, cerebrospinal fluid, and radiological profiles consistent with the diagnosis of AE were enrolled in the study. A clinical profile was noted, and platelet count was assessed. Thrombocytopenia was defined as platelet count <150,000/mm3. Platelet count 100,000-150,000, 50,000-99,999, and <50,000/mm3 were considered mild, moderate, and severe thrombocytopenia.

Almost universally, considerations about the coronavirus pandemic and its effects became priority in the daily operations of businesses, leaving hitherto pressing concerns in the back stage. Early in the pandemic, the management of University of Benin Teaching Hospital set up a Business Continuity Team which undertook an evaluation of the perceptions of mid-level hospital managers about their departments' and units' risks and vulnerabilities in the face of the ongoing pandemic.</p><p><strong>Methods: </strong>A modified International Labour Organization (ILO) risk profile self-assessment tool which focused on \"people,\" \"processes,\" \"profits,\" and \"partnerships\" was used to assess mid-level managers' perceptions of their respective departments' and units' risks and vulnerabilities, consequent on the COVID-19 pandemic.

Among the patients with dysphagia, HREM revealed the highest yield of detecting an abnormal esophageal motility test (70.6%); meanwhile, this yield was much lower in those with GERD (21.8%), chest pain (22.8%), and other symptoms (15.7%). The most common finding among those with dysphagia was Achalasia cardia (55.9%), while the study was normal among those with GERD (78.1%), chest pain (77.1%), and other symptoms (84.2%). The sensitivity and specificity of dysphagia for major motility disorders were 65% and 91%, respectively, with a positive predictive value of 90%.</p><p><strong>Conclusion: </strong>HREM has high accuracy and a good diagnostic yield among patients with dysphagia, with the most common finding being Achalasia cardia.</p>","PeriodicalId":7938,"journal":{"name":"Annals of African Medicine","volume":" ","pages":"617-622"},"PeriodicalIF":0.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11556496/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141974931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
