RESUMO

Resumen El Streptococcus viridans es conocido más comúnmente como agente infeccioso en las endocarditis, sin embargo, poco se conoce sobre su potencial infeccioso en otros órganos o sistemas, donde ha demostrado una elevada mortalidad. El reconocimiento del Streptococcus viridans como agente productor de abscesos en otras localizaciones como a nivel hepático o pulmonar, permitirá un diagnóstico oportuno mediante los distintos métodos de imagen, reduciendo las graves consecuencias para el paciente y los tiempos de hospitalización. Se presenta el caso de un paciente del sexo masculino de 33 años de edad sin antecedentes crónico degenerativos, que inició con sintomatología 7 meses previos a su ingreso, con fiebre intermitente, fatiga, astenia, anorexia y pérdida de peso. A la exploración física presentó dolor a la palpación media y profunda en hipocondrio derecho, en el panel de laboratorios presentó llamativa neutrofilia, en la tomografía de tórax y abdomen se mostró lesión cavernomatosa en pulmón y quistes complicados hepáticos, a los cuales se les realizó drenaje percutáneo guiado por ultrasonido, con envío de muestras a cultivo con resultado positivo para Streptococcus viridans, lo que permitió brindar el tratamiento dirigido al paciente, y que remitiera la enfermedad.


Abstract Streptococcus viridans is more commonly known as an infectious agent in endocarditis, however, little is known about its infectious potential in other organs or systems, where it has shown high mortality. The recognition of Streptococcus viridans as an abscess-producing agent in other locations, such as the liver or lungs, will allow timely diagnosis using different imaging methods, reducing serious consequences for the patient and hospitalization times. We present the case of a 33-year-old male patient with no chronic degenerative history, who started symptoms 7 months prior to admission, with intermittent fever, fatigue, asthenia, anorexia and weight loss, on physical examination he presented pain at the medium and deep palpation in the right hypochondrium, in the laboratory panel I present striking neutrophilia, in the tomography of the thorax and abdomen a cavernous lesion in the lung and complicated hepatic cysts are shown, to which percutaneous drainage guided by ultrasound is performed, with sending of cultured samples with a positive result for Streptococcus viridans. Thus, allowing treatment to be provided to the patient, thereby achieving remission of the disease.

RESUMO

El absceso cerebral es una infección focal, que se presenta con una frecuencia de 0,3-1,3 casos cada 100000 personas/año.¹ Se describe la epidemiología, clínica y microbiología de 38 niños con diagnóstico de absceso cerebral internados entre el 1/4/2005 y el 31/12/2015 en el Hospital de Pediatría "Prof. Dr. Juan P. Garrahan" de la Ciudad de Buenos Aires. Veinticuatro pacientes fueron varones. La mediana de edad fue de 132 meses. Se detectaron factores predisponentes en 25 niños. La mediana de evolución entre el inicio de los síntomas y la consulta fue de 7 días. Hubo 27 casos con lesiones únicas. Se realizó un drenaje quirúrgico en 34 pacientes. Las bacterias más frecuentes fueron anaerobios, Streptococcus viridans y Staphylococcus aureus. La mediana de tratamiento antibiótico fue de 56 días y la mediana de internación fue de 43 días. La letalidad fue del 3%.


Brain abscess is a focal infection that occurs with a frequency of 0.3-1.3 cases per 100,000 people/year. We describe the epidemiology, clinical and microbiology characteristics of 38 children diagnosed with brain abscess hospitalized between 4/1/2005 and 12/31/2015 at Hospital de Pediatría "Prof. Dr. Juan P. Garrahan" in Buenos Aires City. Twenty-four patients were male. The median age was 132 months. Predisposing factors were detected in 25 children. The median evolution from onset of symptoms to the visit was 7 days. There were 27 cases with single lesions. Surgical drainage was performed in 34 patients. The most frequent bacteria were anaerobes, Streptococcus viridans and Staphylococcus aureus. The median of antibiotic treatment was 56 days and the median of hospitalization was 43 days. The lethality was 3%.

RESUMO

La espondilodiscitis infecciosa es una entidad poco frecuente que afecta el disco intervertebral y las vértebras adyacentes. Su importancia clínica radica en la morbilidad que determina. En este caso nos centraremos en la espondilodiscitis piógena (EP) y, dentro de ella, en la estreptocócica. Se presenta el caso clínico de un paciente con espondilodiscitis por Streptoccocus intermedius perteneciente al grupo viridans, se analizan las características clínicas, y se realiza una breve revisión bibliográfica.


Infectious spondylodiscitis is a rare condition that affects the intervertebral disc and adjacent vertebrae. Its clinical relevance is related with its morbidity. In this case we will focus on the pyogenous spondylodiscitis (PS), and more specifically, streptococcal. Clinical case report of a patient with spondylodiscitis caused by Streptoccocus intermedius of the viridans group, with a description of the clinical features and a brief literature review.

RESUMO

Objetivo: Descrever os patógenos isolados em cultura quantitativa de escarro, nas exacerbações agudas de doença pulmonar obstrutiva crônica, em pacientes internados no Hospital Nossa Senhora da Conceição – Tubarão/SC e no Hospital Nereu Ramos – Florianópolis/SC. Metodologia: Foi realizado um estudo de delineamento transversal, utilizando escarro coletado em pacientes internados, o qual foi submetido à cultura quantitativa. Foi utilizada como ponto de corte a presença de 106 ufc/mL. O uso da antibioticoterapia foi confrontado com o isolamento em cultivo de agente etiológico bacteriano, através do índice de concordância Kappa. Resultados: Foram avaliados consecutivamente 13 pacientes, sendo 69,2% pertencentes ao gênero masculino, com média de idade de 67,15. A cultura de escarro evidenciou o crescimento de 53,8% de Streptococcus viridans e 7,7% de Haemophilus influenzae. Em 38,5% das culturas, não houve crescimento bacteriano. Quantificou-se 38,5%(n = 5) das culturas com mais de 106 UFC e 23,1% (n = 3) com menos de 106 UFC. O índice de concordância Kappa entre o uso de antibioticoterapia e a presença de infecção foi de -0,519. Conclusão: Houve um predomínio de pacientes do gênero masculino, e o agente mais comumente isolado nas culturas foi o Streptococcus viridans. Ocorreu discordância entre o uso de antimicronianos e a presença ou ausência de infecção.


Objective: To describe the pathogens isolated through quantitative sputum culture, in acute exacerbations of chronic obstructive pulmonary disease in patients admitted to the Hospital Nossa Senhora da Conceição, Tubarão/SC and Hospital Nereu Ramos, Florianópolis/SC. Methodology: A cross-sectional study was conducted using sputum collected from hospitalized patients, which was subjected to quantitative culture. The presence of 106 cfu/mL was used as a cutoff point. The use of antibiotics was compared with isolation of bacterial culture from the etiologic agent by Kappa index of agreement. Results:Thirteen patients were consecutive evaluated, 69.2% out of them were male, mean age 67.15. Sputum culture showed 53.8% growth of Streptococcus viridans and 7.7% of Haemophilus influenzae. There was no bacterial growth in 38.5% of the cultures. Of the total, 38.5% (n = 5) contained more than 106 CFU and 23.1% (n = 3) contained less than 106 CFU. The Kappaindex of concordance between antibiotic use and the presence of infection was -0.519. Conclusion: There was a predominance of male patients, and the agent most commonly isolated in cultures was Streptococcus viridans. There was disagreement between antimicrobial use and the presence or absence of infection.
