The occult rheumatic scourge: A clinicopathological analysis of missed rheumatic heart disease.

Aims: To study the clinical and pathological manifestations of missed cases of rheumatic heart disease (RHD) and postulate possible reasons behind a missed diagnosis. Materials and Methods: Retrospective 20-year (2000-2019) autopsy data of chronic RHD were reviewed and patients, in whom the valvular deformities had been incidental autopsy findings, were selected. The clinical details of these patients were correlated with the morphology of the affected valves. On this pathological analysis, the patients were assigned to a category of subtle or significant valvular deformity. By clinically correlating, the latter group was subdivided into clinically misdiagnosed, clinically undiagnosed, and sudden cardiac death. Statistical Analysis: Nil. Results: Among the 475 cases of chronic RHD identified at autopsy in the study period, the disease was diagnosed incidentally in 69 patients (14.5%). Significant valvular deformity was noted in 61 cases while the other 8 cases had subtle valvular deformity. The most common cause of death was cardiac failure in 39 out of 69 patients (56%). Eleven (16%) patients had experienced sudden cardiac death. Among the undiagnosed cases, 5 (7%) of them had a diagnosis of non-rheumatic cardiac disease, while the other 14 (20.5%) patients had overwhelming non-cardiac diseases. Conclusions: Our study indicates that mortality and morbidity due to RHD are underdetermined. The patients remain undiagnosed due to either insignificant valvular involvement, clinically silent in the presence of significant valvular deformity, presence of other overwhelming diseases or misdiagnosis partly due to the resemblance with the other pathologies.

Portal system thrombosis in an HIV-infected child.

HIV infection can lead to venous thrombosis due to protein C deficiency, protein S deficiency, or antiphospholipid syndrome. Most patients present with deep vein thrombosis or pulmonary embolism. We report a 10-years-old HIV-infected girl who presented with life-threatening hematemesis. Computed tomography scan of the abdomen and angiography showed thrombosis of the portal vein, superior mesenteric vein, and splenic vein. She was advised antiretroviral therapy and prothrombotic workup, however, she took discharge against medical advice.

Acute rheumatic fever - A pathological analysis of clinically missed cases.

BACKGROUND: Acute rheumatic fever (ARF) and its post-inflammatory sequel chronic rheumatic heart disease (RHD) are endemic in the Indian setting. Despite the updated Jones criteria, many cases of ARF remain undiagnosed or are missed. AIMS: This study aims to analyze pathological profiles of such cases and their importance in context of clinical presentation and Jones criteria. MATERIALS AND METHODS: A 22-year retrospective observational study of ARF was conducted in the Department of Pathology in a tertiary care institute. The cases were categorized as 1. Those fulfilling and 2. those partially or not fulfilling the Jones Criteria. Based on the autopsy findings, the lesions were classified as categorized mitral stenosis and/or regurgitation (MS ± MR) and pure mitral regurgitation (MR). STATISTICAL ANALYSIS: Nil. RESULTS: In 22 years, among 697 cases of autopsied cases of RHD, there were 59 cases (8.5%) of ARF. Among them, seven cases fulfilled the Jones criteria; five of them were clinically diagnosed. The remaining 52 cases (88.1%, 34 with MS ± MR and 18 with MR) did not fulfill or partially fulfilled the Jones criteria and were not diagnosed. A total of 18 patients (30.5%) had the first attack of ARF, whereas recurrences were noted in the remaining patients (69.5%). CONCLUSIONS: The study indicates that the typical manifestations of ARF under Jones criteria may not be present, especially in cases with recurrence. Hence, a presumptive or possible diagnosis of ARF can be made with presence of minor criteria or strong clinical suspicion in such cases.
