ABSTRACT
Background Owing to the lack of standardised audio-visual (A-V) instructions to take photographs, patients with pemphigus faced difficulties during tele-consultation in COVID-19 pandemic. Objective To construct and validate an A-V instruction tool to take photographs of skin and oral cavity lesions of pemphigus. Methods In this observational study, we included patients with pemphigus of either gender seeking tele-consultation, aged 18 years or older. A-V instructions demonstrating skin and oral cavity photography were designed and shared with the patients. They were requested to send pictures of lesions that complied with the instructions. They were then required to complete a 10-item questionnaire for face validation in the two following rounds. The videos were content validated by 14 experts in the field of clinical dermatology. Results Forty-eight patients took part in face validation. A majority of patients, 47 (97.9%) and 45 (93.8%); rated the audio and video quality as being above average, respectively. Forty-seven patients (97.9%) said the instructional videos were useful, and 42 patients (87.5%) said they did not need to take any further images to show how severe their disease was. The average scale content validity index for the instructions on skin imaging and the oral cavity imaging during round 1 of content validation was 0.863 and 0.836, respectively. Limitation Validated instruction videos are in Hindi language and need to be further translated and validated in other local languages for use in non-Hindi speaking regions. Conclusion A-V instructions were useful to take photographs during tele-consultation.
ABSTRACT
BACKGROUND: Kounis syndrome, also known as "allergic myocardial infarction," is a rare co-occurrence of acute coronary syndrome (ACS) in the setting of hypersensitivity reaction to any agent. Non-steroidal anti-inflammatory drugs (NSAIDs) like are often implicated in causing allergic reactions. Here, we present a case of anterior wall myocardial infarction (AWMI) occurred following angioedema secondary to intake of Nimesulide, not described earlier in literature. CASE PRESENTATION: A 45-year-old female developed generalized pruritic, erythematous maculopapular rash, facial puffiness, oral ulcers and hoarseness of voice within few hours following consumption of Nimesulide for fever and body-ache. Due to development of hypotension, electrocardiogram (ECG) was done, which revealed ST elevation in V2-V6, with marked elevation of troponin (TnI) and creatine kinase (CK-MB). He had no chest pain or shortness of breath. Echocardiography showed regional wall motion (RWMA) abnormality in left anterior descending artery (LAD) territory with an ejection fraction of 25%. Coronary angiography showed a complete thrombotic cutoff of LAD, for which Tirofiban infusion was started to decrease thrombus burden. Repeat angiography on next day showed 80% lesion in proximal LAD for which she underwent revascularization with a drug-eluting stent. The patient later showed improvement in cardiac function at 8 months of follow-up. CONCLUSIONS: The occurrence of ACS requiring percutaneous coronary intervention (PCI) in the setting of allergic reactions is rarely reported in the literature. One should be aware of the rare possibility of Kounis syndrome in the setting of hypersensitivity reaction when accompanying features of symptoms suggestive of coronary artery disease co-exists. When indicated, ECG monitoring and cardiac biomarkers in patients with allergic responses help to identify this rare and treatable condition.
