Perioperative Kounis syndrome in an older adult

Introduction: Kounis syndrome (KS) is myocardial ischemia secondary to the release of inflam matory mediators (mastocyte degranulation) during an allergic reaction. Adult anaphylaxis is often triggered by medications, of which antibiotics are the most frequently reported. Objective: to study the presentation of and clinical approach to a patient with Kounis syndrome and increase the diagnostic suspicion of a disease which does not have a standardized treatment and is not supported by clinical practice guidelines. Case presentation: we present the case of a 62-year-old adult patient with chest pain and anginal equivalents following perioperative anaphylactic shock during a scheduled open cholecystectomy for gallstones, with subsequent acute myocardial infarction without ST elevation, and coronary artery lesions or atheromatous disease ruled out by arteriography. Conclusions: Kounis syndrome is an underdiagnosed entity with a variable clinical presenta tion and no concrete or standardized treatment. This therefore encourages the development of a greater case history and the structuring of widely disseminated guidelines for its treatment. (Acta Med Colomb 2022; 47.

Introducción: el síndrome de Kounis (SDK) corresponde a una isquemia miocárdica secundaria a la liberación de mediadores inflamatorios (degranulación de mastocitos) durante una reacción alérgica. La anafilaxia en adultos comúnmente es desencadenada por medicamentos, de los cuales los antibióticos son los más frecuentemente informados. Objetivo: estudiar la forma de presentación y abordaje clínico de un paciente con síndrome de Kounis y aumentar la sospecha diagnóstica de una patología que no tiene un tratamiento estanda rizado o respaldado por guías de práctica clínica. Presentación de caso: se presenta el caso de una paciente adulta de 62 años con dolor pre cordial y equivalentes anginosos posterior a un choque anafiláctico perioperatorio durante una colecistectomía abierta realizada de forma programada por colelitiasis, con posterior infarto agudo de miocardio sin elevación del ST, con arteriografía que descartó lesiones en arterias coronarias o enfermedad ateromatosa. Conclusiones: el síndrome de Kounis es una entidad subdiagnosticada, con presentación clínica variable y sin un tratamiento concreto o estandarizado, lo que motiva a realizar una mayor casuística y estructurar recomendaciones de amplia difusión respecto a su tratamiento.

Role of oncogenic viruses in the development ocular surface squamous neoplasia.

PURPOSE: The pathogenesis of ocular surface squamous neoplasia is not fully understood. Therefore, we evaluated the role of oncogenic viruses in the pathogenesis of ocular surface squamous neoplasia in Israel. METHODS: Patients with ocular surface squamous neoplasia were enrolled in this retrospective study. The specimens were taken during 2004-2015 from two big centers: Emek Medical Center, Afula and the Hadassah Medical Center, Jerusalem. All the specimens (totally 26) were analyzed by immunohistochemistry for evidence of oncogenic viruses that included Human Papilloma virus, Herpes Simplex virus and Cytomegalovirus infection and 14 samples were examined by polymerase chain reaction. In addition, all the samples were examined for Epstein Barr virus infection by immunohistochemistry and Epstein Barr encoding region test. RESULTS: Twenty-six patients were included with a mean age of 61.81 [Formula: see text] 3.83 years (mean [Formula: see text]. Immunohistochemistry staining and Epstein Barr encoding region test did not detect any of the oncogenic viruses in the 26 samples. Human Papilloma virus-16 and -18, and Herpes Simplex virus were detected by polymerase chain reaction in 14.2%, 7% and 7%, respectively. CONCLUSION: We conclude from our study that oncogenic viruses may play a role in the pathogenesis of ocular surface squamous neoplasia in Israel.

Pancreatitis crónica calcificante en un paciente con enolismo y tabaquismo pesado / Chronic calcifying pancreatitis in a patient with enolism and heavy smoking

Hombre de 62 años con enolismo crónico y tabaquismo pesado activo, síntomas de 3 meses de evolución consistente principalmente en deposiciones diarreicas amarillentas, flotantes, fétidas, 12 diarias, que no mejoran con el ayuno, lo despiertan en la noche, con meteorismo y dolor abdominal, perdida de 12 kg de peso y edemas periféricos. La tomografía de abdomen confirmo la sospecha de pancreatitis crónica e insuficiencia exocrina como causal de la diarrea crónica y esteatorrea (1). La pérdida de peso y malnutrición son hallazgos frecuentes, para el manejo se requiere de enzimas pancreáticas a más de 40.000 U con cada comida(2). El alcoholismo y el tabaquismo activo aceleran y contribuyen al progreso de calcificación (3)(4) y en esta fase hasta el 90 % de los pacientes presentaran diabetes mellitus(5).
