ABSTRACT
Introducción: las infecciones estreptocócicas pueden presentarse con fiebre, inflamación faringoamigdalina con o sin exudados, petequias en el paladar, adenitis cervical, exantema escarlatiniforme y / o dolor abdominal. Resulta útil en área de urgencia disponer de pruebas de detección rápida de antígenos de S. pyogenes (DRASP) de alta especificidad y sensibilidad algo menor. Objetivos: conocer la utilidad de un test de DRASP en 2 servicios de Urgencia Pediátrica, describiendo las características clínicas y epidemiológicas de los pacientes estudiados durante el período de la investigación y su correlación con el cultivo de exudado faríngeo mediante el cálculo de sensibilidad (S), especificidad (E), valor predictivo positivo (VPP) y valor predictivo negativo (VPN). Material y métodos: estudio prospectivo, observacional, transversal en dos servicios de emergencia pediátrica. Se incluyeron niños a los que se les realizó DRASP y exudado faríngeo (EF) entre el 14 de febrero y el 13 de abril de 2018. Se registró: sexo, edad, motivo de consulta, diagnóstico, tratamiento, destino, resultado del test y de cultivo faríngeo. Se calcularon S, E, VPP y VPN. Resultados: n=241 niños. Rango 8 meses - 14 años, media 6 años. Consultaron por fiebre 103 niños (42,7%); por odinofagia 48, por erupción 11 y 47 por otros síntomas. Al 95% de los niños se le otorgó el alta. DRASP negativos 87,6% (N: 211) y positivos 12,9% (N: 31). EF negativos 80,1% (n: 193) y positivos para SßHGA en 13,7% (n: 33). La sensibilidad de la prueba fue del 52% y su especificidad del 93%. El VPP 55% y el negativo 92%. El diagnóstico más frecuente fue faringitis viral 132 (54,7%). Conclusiones: el test se aplicó fundamentalmente a escolares febriles, algunos con odinofagia. Contribuye a diferenciar en forma rápida la etiología y habilita a no usar antibióticos en caso de resultado negativo. Estos resultados avalan el uso de DRASP en la urgencia pediátrica.
Introduction: streptococcal infections can show fever, pharyngotonsillar inflammation with or without swabs, palatal petechiae, cervical adenitis, scarlatiniform rash and/or abdominal pain. Rapid detection tests for S. pyogenes antigens (DRASP) with high specificity and somewhat lower sensitivity are a useful at the Emergency Ward. Objectives: know the usefulness of a DRASP test in 2 Pediatric Emergency, describe the clinical and epidemiological characteristics of the patients studied during the research period and its correlation with the culture of pharyngeal exudates by calculating sensitivity (S) , specificity (S), positive predictive value (PPV), and negative predictive value (NPV). Material and Methods: prospective, observational, cross-sectional study carried out in two pediatric emergency wards. We included children who underwent DRASP and pharyngeal swab (PS) between February 14 and April 13, 2018. The following data were recorded: sex, age, reason for consultation, diagnosis, treatment, destination, test results and throat cultures. S, S, PPV and NPV were calculated. Results: n=241 children. Range 8 months - 14 years, average 6 years. 103 children (42.7%) consulted due to fever; 48 due to sore throat, 11 due to rash and 47 due to other symptoms. 95% of children were discharged. DRASP negative 87.6% (N: 211) and positive 12.9% (N: 31). Negative EP 80.1% (n: 193) and positive for SßHGA in 13.7% (n: 33). The test sensitivity was 52% and specificity 93%. The PPV 55% and the negative 92%. The most frequent diagnosis was viral pharyngitis 132 (54.7%). Conclusions: the test was applied mainly to febrile schoolchildren, some with odynophagia. A quick etiology differentiation is helpful, since it prevents antibiotics from being used in the event of a negative result. These results support the use of DRASP in pediatric emergency wards.
Introdução: as infecções estreptocócicas manifestam-se com febre, inflamação faringotonsilar com ou sem exsudado, petéquias palatinas, adenite cervical, erupção cutânea escarlatiniforme e/ou dor abdominal. Nos serviços de emergência é útil realizar testes de detecção rápida para antígenos de S. pyogenes (DRASP) com alta especificidade e sensibilidade um pouco mais baixa Objetivos: conhecer a utilidade do teste DRASP em 2 Emergências Pediátricas, descrever as características clínicas e epidemiológicas dos pacientes estudados durante o período da pesquisa e sua correlação com a cultura de exsudatos faríngeos por meio do cálculo de sensibilidade (S) , especificidade (S), positivo valor preditivo (VPP) e valor preditivo negativo (VPN). Material e métodos: estudo prospectivo, observacional, transversal, realizado em duas unidades de emergência pediátrica. Foram incluídas crianças que realizaram DRASP e swab faríngeo (PS) entre 14 de fevereiro e 13 de abril de 2018. Foram registrados os seguintes dados: sexo, idade, motivo da consulta, diagnóstico, tratamento, destino, resultados de exames e culturas de garganta. S, S, VPP e VPN foram calculados. Resultados: n=241 crianças. Faixa 8 meses - 14 anos, média 6 anos. 103 crianças (42,7%) consultadas por febre; 48 por dor de garganta, 11 por erupção cutânea e 47 por outros sintomas. 95% das crianças receberam alta. DRASP negativo 87,6% (N: 211) e positivo 12,9% (N: 31). EP negativo 80,1% (n: 193) e positivo para SßHGA em 13,7% (n: 33). A sensibilidade do teste foi de 52% e a especificidade de 93%. O PPV 55% e o negativo 92%. O diagnóstico mais frequente foi faringite viral 132 (54,7%). Conclusões: o teste foi aplicado principalmente em escolares febris, alguns com odinofagia. A rápida diferenciação etiológica é útil, pois evita o uso de antibióticos em caso de resultado negativo. Esses resultados apoiam o uso do DRASP em enfermarias de emergência pediátrica.

Introduction: Dysphagia can cause significant morbidity and mortality, especially in the elderly and the paediatric population. The study was undertaken to determine the clinico-pathological profile of the patients diagnosed with oesophageal dysphagia in a rural tertiary care hospital of India. Methods: This cross sectional, descriptive study was carried out in the ENT Department of Rural Medical College and Pravara Rural Hospital, Loni, Maharashtra. Patients attending the ENT Out Patient Department during 2009 and later diagnosed as cases of oesophageal dysphagia formed the statistical sample. Results: Out of 61 patients, 37 were male and 24 female. Majority of the patients belonged to age group 41-50 years (24.6%), were farmer by occupation (31.1%) and belonged to middle socioeconomic status (34.4%). Pain (throat, retrosternal or epigastric) was the most common (70.5%) presenting complaint. For 39.3% study subjects, the presenting complaint was 3 to 6 months old. Barium swallow study revealed a positive finding in 74.1% (n=40/54) patients, with carcinoma of oesophagus (27.8%) as the most common aetiology, followed by motility disorders and benign strictures. Oesophagoscopy detected lesions in 49 (90.74%) cases and like barium swallow, it also detected carcinoma oesophagus as the most common cause of oesophageal dysphagia. Reflux oesophagitis was the most common form of the oesophagitis and the microbiological examination and culture of samples of 14 patients diagnosed with any form of oesophagitis showed Candida albicans in 21.4%. Conclusion: Dysphagia is a common presenting complaint in the ENT clinic. There is a male preponderance with incidence of malignancy rising with age. Barium swallow may be used as the first line of investigation; however, oesophagoscopy gives a better diagnosis.

Introducción: La faringoamigdalitis aguda (FAA) es un cuadro infeccioso producido por numerosos agentes etiológicos, siendo Streptococcus pyogenes (SP) el más frecuentemente involucrado y el principal responsable de potenciales complicaciones. Objetivo: El objetivo del estudio fue determinar la prevalencia de éste y otros microorganismos en una muestra de población pediátrica y adulta. Material y método: Se diseñó un estudio prospectivo de casos y controles en pacientes que consultaron en forma consecutiva por odinofagia con signos de inflamación faringoamigdalina. Resultados: Se obtuvo un examen completo incluyendo un cultivo faríngeo en 159 pacientes entre 3 y 55 años. Entre los síntomas relevantes destacaron: cefalea, fiebre, adenopatíasy exudado. En adultos, 29 por ciento de las FAA fueron causadas por SP, mientras que en niños sólo 17 por ciento. En ningún paciente control se objetivó la presencia de SP. Conclusión: No existió correlación entre las características clínicas y la presencia de SP. De acuerdo a estos resultados se sugiere la realización rutinaria de un estudio etiológico al enfrentarse a una FAA.
Acute pharyngotonsillitis (APT) is an infectious disease that can be caused by numerous etiologic agents, with Streptococcus pyogenes (SP) being the most frequently involved and the main cause of potential complications. This study was aimed to determine the prevalence of this and other microorganisms in a sample of a pediatric and adult population. A prospective study of cases and controls was designed in patients that presented consecutively with odynophagia and pharyngotonsilar inflammation. A complete exam was performed, including pharyngeal culture in 159 patients between 3 and 55 years of age. Among relevant symptoms we found: headache, fever, lymphadenopathy and tonsilar exúdate. 29 percentofAPTs were caused by SP in adults, and only 17 percent In children. Conclusions: There was no correlation between clinical characteristics and SP presence. According to these results, a routine etiologic study is suggested when facing an APT.
