ABSTRACT

Introducción: la sepsis tardía por estafilococo coagulasa negativo (SCoN) es una causa común de morbimortalidad en la unidad neonatal. Los SCoN son los microorganismos más frecuentemente involucrados con aproximadamente el 50% de los casos. El objetivo de este estudio es analizar la incidencia y las características de los neonatos portadores de sepsis tardía por SCoN. Materiales y métodos: se realizó un estudio descriptivo, longitudinal, retrospectivo. Se utilizaron las bases de datos del laboratorio de microbiología del hospital y las historias clínicas electrónicas para obtener la información. El período de estudio analizado fueron los años 2018 y 2019 en la unidad de cuidados intensivos e intermedios de recién nacidos del Centro Hospitalario Pereira Rossell. Resultados: obtuvimos una incidencia de 2,5% de los ingresos a cuidados intensivos e intermedios (25 pacientes). La edad gestacional al nacer fue de 28 semanas (25,0-35,0) y la mediana del peso fue de 1.070 g (730,0-2.365,0). La media de edad gestacional posmenstrual al momento del diagnóstico fue de 32,92±7,921 semanas. Por sospecha de sepsis precoz, 17 pacientes habían recibido un curso de antibióticos previo. El signo clínico más frecuentemente observado fue el deterioro del estado general, en 11 pacientes, seguido de distensión abdominal en 6 y fiebre en 5. Dentro de los SCoN, el más frecuentemente aislado fue el Staphylococcus epidermidis (13 pacientes); 22 pacientes recibieron tratamiento, 18 de ellos con vancomicina-meropenem y 4 con monoterapia con vancomicina. Conclusión: estos patógenos representan una causa importante de morbimortalidad en la unidad neonatal, particularmente en pacientes que presentan mayor gravedad y mayor necesidad de soporte vital. Se necesitan pautas claras de interpretación del rol de estos microorganismos y de abordaje de pacientes con riesgo de sepsis tardía, incluyendo el tratamiento antibiótico empírico.


Introduction: Coagulase Negative Staphylococci (CoNS) late onset sepsis is a common cause of morbidity and mortality in the neonatal intensive care unit (NICU). CoNS are the most frequently isolated microorganisms and total 50% of cases. The objective of this study is to analyze the incidence and characteristics of newborns carriers of late onset CoNS. Materials and methods: we performed a descriptive, retrospective, longitudinal study. Data was obtained from the hospital's microbiology laboratory database and electronic medical records. Patients included were those admitted to NICU during the period between 2018 and 2019. Results: we obtained an incidence of 2.5% of patients admitted to the NICU (25 patients). Median gestational age at birth was 28 weeks 25.0-35.0 and median birth weight was 1.070 g 730.0-2365.0. Mean gestational age at the time of diagnosis was 32.92±7.921 weeks. 17 patients had received an antibiotics course at birth because of early onset sepsis suspicion. The most frequently observed clinical symptom was deterioration of general condition, 11 patients, followed by abdominal distention in 6 and fever in 5. Among CoNS, the most frequently isolated pathogen was Staphylococcus epidermidis (13 patients). 22 patients received treatment, 18 a combination of vancomycin and meropenem and 4 received vancomycin monotherapy. Conclusion: these pathogens are a common cause of morbidity and mortality in the newborn intensive care unit, particularly in patients with more serious conditions and in those who require more advanced life support measures. Clearer interpretation of their role is needed as well as to determine a proper approach to patients at risk of late onset sepsis, including empiric antibiotic treatment.


Sepse tardia para Staphylococcus coagulase negativa (SCoN) é uma causa comum de morbidade e mortalidade na unidade neonatal. SCoNs são os microrganismos mais frequentemente envolvidos e representam aproximadamente 50% dos casos. O objetivo deste estudo é analisar a incidência e as características de neonatos com sepse tardia por SCoN. Materiais e métodos: foi realizado um estudo descritivo, longitudinal e retrospectivo. Usamos os bancos de dados do laboratório de microbiologia e prontuários médicos eletrônicos de nosso hospital para obter as informações. O período de estudo analisado foi de 2018 e 2019 na unidade de terapia intensiva e intermediária para recém-nascidos do Centro Hospitalar Pereira Rossell. Resultados: obtivemos uma incidência de 2,5% de internações em Terapia Intensiva e Intermediária (25 pacientes). A idade gestacional ao nascer foi de 28 semanas 25,0-35,0 e o peso médio foi de 1070g 730,0-2365,0. A média da idade gestacional pós-menstrual no momento do diagnóstico foi de 32,92 ± 7,921 semanas. 17 pacientes haviam recebido um curso anterior de antibióticos por suspeita de sepse precoce. O sinal clínico mais frequentemente observado foi deterioração do estado geral em 11 pacientes, seguido por distensão abdominal em 6 e febre em 5. Dentre os SCoN, o mais isolado foi o Staphylococcus Epidermidis (13 pacientes). 22 pacientes receberam tratamento, 18 deles com Vancomicina-Meropenem e 4 com Vancomicina em monoterapia. Conclusão: esses patógenos representam uma importante causa de morbimortalidade na unidade neonatal, principalmente em pacientes com maior gravidade e maior necessidade de suporte de vida. Orientações claras são necessárias para interpretar o papel desses microrganismos e para abordar pacientes com risco de sepse tardia, incluindo tratamento com antibióticos.

ABSTRACT

Los estafilococos coagulasa negativos son microorganismos frecuentemente aislados cuya significancia clínica puede ser difícil de establecer por su carácter de comensales habituales de la piel. En la población neonatal estos patógenos han ido adquiriendo mayor protagonismo debido a la sobrevida de pacientes mas prematuros que en el pasado, así como sus necesidades de tratamiento, que determinan mayores tiempos de estadía hospitalaria. Estos elementos representan factores de riesgo también para el desarrollo de endocarditis en estos pacientes, particularmente debido a la utilización de catéteres intravasculares centrales por tiempo prolongado. En este caso clínico se presenta un paciente pretérmino severo que presentó una endocarditis a estafilococo coagulasa negativo a partir del cual discutiremos las características de las infecciones por estos microorganismos, las características de la endocarditis infecciosa en el recién nacido pretérmino y la utilización de antibióticos en estos pacientes, así como algunos elementos asociados a la vigilancia activa en el uso de antibióticos.


Coagulase negative staphylococcus (CoNS) are commonly isolated microorganisms whose clinical importance may be difficult to establish due to their role as part of our usual skin microbiota. These pathogens have gained relevance in neonatal population due to an improvement in neonatal care that determine longer survival rates and hospitals stays. Neonatal endocarditis is also affected by these microorganisms and particularly by the use of central intra vascular lines for long periods of time. In this clinical case we introduce a severe preterm patient who developed a CoNS endocarditis and discuss the characteristics of CoNS infections and endocarditis in preterm newborns as well as some antibiotic vigilance principles.


Os estafilococos coagulase negativos são microrganismos frequentemente isolados, cujo significado clínico pode ser difícil de estabelecer devido ao seu caráter de comensais cutâneos comuns. Na população neonatal, esses patógenos vêm adquirindo maior destaque devido à sobrevida de pacientes mais prematuros do que no passado, bem como suas necessidades de tratamento, as quais determinam tempos de internação mais longos. Esses elementos também representam fatores de risco para o desenvolvimento de endocardite nesses pacientes, principalmente pelo uso prolongado de cateter intravascular central. Neste caso clínico apresentaremos um paciente pré-termo grave que apresentou endocardite estafilocócica coagulase-negativa a partir do qual discutiremos as características das infecções por esses microrganismos, as características da endocardite infecciosa no recém-nascido pré-termo e o uso de antibióticos nesses pacientes bem como alguns elementos associados à vigilância ativa no uso de antibióticos.

ABSTRACT

Introducción: La osteomielitis mandibular crónica es considerada como una infección odontogénica que cursa con tumefacción de la cara, limitación de la abertura bucal y dolor. Pocas veces es tratada a través de gammagrafías con fijación a ciprofloxacino con la consiguiente obtención de resultados efectivos. Objetivo: Describir un caso clínico de osteomielitis mandibular crónica tratada con terapia antibiótica y quirúrgica. Presentación de caso: Paciente femenina de 63 años de edad que acudió al servicio de estomatología del Hospital María Auxiliadora, Lima, Perú; con un historial de tres meses de hinchazón creciente a nivel del borde inferior izquierdo de la mandíbula desde que le realizaron una extracción dentaria. Los exámenes tomográficos, gammagrafía, biopsia y antibiograma confirmaron la osteomielitis y la susceptibilidad bacteriana. La decorticación, debridamiento, exodoncia y la administración de metronidazol más vancomicina por dos meses permitió la remisión del cuadro. Conclusiones: El seguimiento clínico de dos años y las gammagrafías de evaluación permitieron verificar la presencia de regeneración ósea y ausencia de focos de reactivación. La osteomielitis crónica puede ser provocada por restos de exodoncias dentarias. Su diagnóstico y seguimiento clínico requiere de múltiples exámenes y controles a largo plazo(AU)


Introduction: Chronic mandibular osteomyelitis is considered to be an odontogenic infection manifesting as facial tumefaction, limited mouth opening and pain. It is not often enough treated with ciprofloxacin fixation gammagraphies with the consequent achievement of effective results. Objective: Describe a clinical case of chronic mandibular osteomyelitis treated with antibiotic and surgical therapy. Case presentation: A female 63-year-old patient attends the dental service at María Auxiliadora Hospital in Lima, Peru, with a history of three-months' swelling of the lower left edge of her mandible upon performance of a dental extraction. Tomographic examination, gammagraphy, biopsy and antibiograms confirmed the presence of osteomyelitis and bacterial susceptibility. Decortication, debridement, exodontia and administration of metronidazole plus vancomycin for two months led to remission of the patient's status. Conclusions: Two-year clinical follow-up and evaluation gammagraphies made it possible to verify the presence of bone regeneration and the absence of reactivation foci. Chronic osteomyelitis may be caused by remains of dental exodontias. Its diagnosis and clinical follow-up require a large number of long-term tests and controls(AU)

ABSTRACT

Introducción: El objetivo del trabajo es evaluar y comparar de manera retrospectiva la tasa de artritis séptica (AS) postquirúrgicas en reconstrucción de LCA entre dos grupos de estudio: A, sin el uso local de vancomicina en el injerto autólogo de isquiotibiales, versus grupo B, con profilaxis antibiótica local.Materiales y métodos: se trabajaron dos grupos compuestos por 683 pacientes en total, con diagnóstico primario de ruptura de LCA. Grupo A, operados entre 2016 y 2017, en los que no se utilizó profilaxis antibiótica del autoinjerto; y el grupo B, intervenidos entre 2018 y 2019, donde se sumergió el autoinjerto de isquiotibiales en 500 mg de vancomicina en 100 ml de solución fisiológica como profilaxis local. En ambos grupos se llevó a cabo el protocolo usual pre, intra y postquirúrgico. Resultados: se analizó la relación entre presencia de infección y las diferentes variables estudiadas, se observó que el uso local de vancomicina en el injerto autólogo de isquiotibiales está asociado a menor infección (p <0.05). La edad, el sexo y el sanatorio donde se realiza la cirugía no condicionan necesariamente la presencia de infección (p >0.05).Conclusión: presentamos este trabajo como prueba en nuestro medio del claro beneficio que se obtuvo, ya que los pacientes que fueron sometidos a la profilaxis local de vancomicina del autoinjerto mostraron una disminución notable de artritis séptica.Tipo de estudio: Artículo Original ­ Descriptivo-transversal. Nivel de evidencia: III


Introduction: The aim of the study is to evaluate and retrospectively compare the rate of postoperative septic arthritis (SA) in ACL reconstruction, between two study groups: A without local use of vancomycin in autologous hamstring graft versus group B with local antibiotic prophylaxisMaterials and methods: two groups composed of 683 patients in total, with a primary diagnosis of ACL rupture, were studied. Group A, operated on in 2016 and 2017, in which antibiotic prophylaxis of the autograft was not used; and the second group B, between 2018 and 2019, where the hamstring autograft was submerged in 500 mg of vancomycin in 100 ml of physiological solution as local prophylaxis. Preoperative intravenous antibiotic prophylaxis was carried out in both groups as the usual protocol.Results: it was obtained as a result that in group A, the two years that they worked without "pre-soaking" of antibiotics in the autograft and the relationship between the presence of infection and the different variables studied was analyzed, where they found that the use Local vancomycin in the autologous hamstring graft is associated with a minor infection (p <0.05). However, age, sex and the sanatorium where the surgery is performed do not necessarily determine the presence of infection (p >0.05)Conclusion: we present this work as proof in our environment of the clear benefit that we obtained, since the patients who underwent local prophylaxis of vancomycin of the autograft, showed a notable decrease in septic arthritis.Type of study: Original Article - Descriptive-cross-sectional. Level of Evidence: III

ABSTRACT

Introducción: Las infecciones asociadas a los cuidados sanitarios en los servicios de atención al paciente crítico se asocian a un alto riesgo de muerte y costos significativos. Objetivo: Identificar los gérmenes más frecuentes en los cultivos y su resistencia a los antimicrobianos en la terapia intensiva del Hospital Clínico Quirúrgico Provincial Dr. Joaquín Albarrán. Métodos: Se realizó un estudio descriptivo, retrospectivo, en la terapia intensiva del Hospital Clínico Quirúrgico Provincial Dr. Joaquín Albarrán, de enero del 2015 a diciembre del 2018, el universo estuvo constituido por 1847 cultivos realizados seleccionándose 654 en los que se obtuvo crecimiento; para el análisis estadístico se utilizó el SPSS 22.0. Resultados: De los gérmenes aislados, la Klebsiella spp fue la más frecuente (31 por ciento), seguida del Staphylococcus spp (24,5 por ciento) y de la E. coli (9,8 por ciento). En los esputos se mantuvo la Klebsiella spp (45,1 por ciento), en los hemocultivos el Staphylococcus spp (53,6 por ciento) y en los urocultivos la Candida (41,1 por ciento), seguida de la E. coli (27 por ciento). De los antimicrobianos usados en terapia para tratar la Klebsiella spp, la E. coli, el Acinetobacter y la pseudomona spp, el más recomendado es la colistina (0-25 por ciento de resistencia) y para el Staphylococcus spp, la vancomicina (1,8 por ciento). Conclusiones: Los gérmenes Gram negativos siguen siendo los más frecuentemente aislados en los cultivos de los pacientes hospitalizados en terapia, con un alto nivel de resistencia para la mayoría de los antibióticos(AU)


Introduction: Infections related to critical care settings are associated to high death risk and significant costs. Objective: Identify the germs most commonly found in cultures and their resistance to antimicrobials in the intensive care service of Dr. Joaquín Albarrán Provincial Clinical Surgical Hospital. Methods: A retrospective descriptive study was conducted at the intensive care service of Dr. Joaquín Albarrán Provincial Clinical Surgical Hospital from January 2015 to December 2018. The study universe was 1 847 cultures, from which 654 were selected in which growth was obtained. Data were processed with the statistical software SPPS 22.0. Results: Of the germs isolated, Klebsiella spp. were the most common (31 percent, followed by Staphylococcus spp. (24.5 percent) and E. coli (9.8 percent). Klebsiella spp. were frequent in sputum cultures (45.1 percent), Staphylococcus spp. in blood cultures (53.6 percent) and Candida in urine cultures (41.1 percent), followed by E. coli (27 percent). Among the antimicrobials used to treat Klebsiella spp., E. coli, Acinetobacter and Pseudomonas spp., the most recommended is colistin (0-25 percent resistance) and vancomycin for Staphylococcus spp. (1.8 percent). Conclusions: Gram-negative germs continue to be the most commonly isolated in cultures from intensive care patients, with a high level of resistance to most antibiotics(AU)

ABSTRACT

Introducción: la zigomicosis es una infección fúngica poco frecuente, con alta tasa de mortalidad y de mal pronóstico. Afecta principalmente a pacientes inmunocomprometidos. La asociación con el síndrome hemofagocítico es extremadamente inusual, más aún en pacientes inmunocompetentes, con pocos ejemplos registrados en la literatura. Caso clínico: se presenta el caso de un paciente masculino inmunocompetente de 40 años con diagnóstico de mucormicosis y síndrome hemofagocítico que evoluciona desfavorablemente, con fallo multiorgánico, a pesar de los esfuerzos médicos. Conclusión: la asociación de mucormicosis con síndrome hemofagocítico en un paciente inmunocompetente es extremadamente rara; existen pocos casos informados en Latinoamérica. Debemos tener presente esta asociación, ya que requiere un tratamiento agresivo y soporte vital avanzado. (AU)


Introduction: zygomycosis is a rare fungal infection that carries with high mortality rates. This poor prognosis, rapidly progressive infection mainly affects immunocompromised patients. The association with hemophagocytic lymphohistiocytosis is extremely unusual, even more in immunocompetent patients, with few cases reported. Case: we present the case of an immunocompetent male patient who was diagnosed with zygomycosis and hemophagocytic lymphohistiocytosis. Despite medical efforts he developed multiorganic failure. Conclusion: the association of mucormycosis with hemophagocytic lymphohistiocytosis in an immunocompetent patient is exceptional with few cases reported in Latin America. We must always suspect this association considering they require aggressive treatment and advanced life support. (AU)

ABSTRACT

Introducción: El término ''síndrome antifosfolipídico'' (SAF) describe la asociación de los anticuerpos antifosfolipídicos (AAF) con un cuadro clínico de hipercoagulabilidad caracterizado por trombosis a repetición y abortos recurrentes. Objetivo: Presentar un caso de celulitis severa de periné en paciente con SAF y tratamiento con hidroxicloroquina. Caso clínico: Paciente de 39 años con embarazo de término con SAF tratado con hidroxicloroquina y anticoagulación que desarrolló una infección severa de partes blandas del periné que fue tratado con interrupción del embarazo, drenaje agresivo del periné y tratamiento antibiótico extenso con buena evolución. Conclusión: La asociación del tratamiento con hidroxicloroquina, embarazo y una complicación séptica es incierta. El tratamiento con inmunosupresión no es estándar y podría haber favorecido el mal pronóstico del cuadro clínico. (AU)


Objetive: To present a case of severe perineal cellulitis in a pregnant patient with Antiphospholipid syndrome treated wiht hidroxicloroquine. Case report: A 39 years old female pregnant patient with AFS treated with hidroxicloroquine and heparin developed severe perineal infection with systemic impairment. Final treatment included aggressive perineal drainage in multiple sessions, pregnancy delivered and systemic treatment with wide spectrum antibiotics and general measures. Discusion and Conclusion: Treatment with hidroxicloroquine, pregnancy and septic complication is infrequent. This approach is not standard and it could favored worst prognostic of the general syndrome. (AU)

ABSTRACT

RESUMO Objetivo: A pneumonia necrosante (PNS) é uma grave e rara complicação da pneumonia adquirida na comunidade, acometendo principalmente crianças, sendo assim, objetivamos analisar prontuários de crianças submetidas ao tratamento cirúrgico de PNS e comparação dos resultados obtidos com os presentes na literatura médica. Métodos: Análise retrospectiva dos prontuários de crianças submetidas ao tratamento cirúrgico por PNS entre julho de 2006 a julho de 2016 em dois hospitais do sul de Santa Catarina, Brasil. Resultados: Do total de 26 crianças, com mediana de idade 2,70 anos, maioria mulheres (61,5%). Os principais sintomas foram febre (88,5%) e tosse (65,4%). Houve média de 4,31 antibióticos utilizados por paciente. O principal agente etiológico foi o Staphylococcus aureus (23,1%) mas as culturas foram negativas em 69% dos pacientes. Em 23 pacientes realizou-se decorticação e desbridamento das áreas necróticas (88,5%). A média de drenagem pleural pós-operatória foi 8,12 dias. Fístula broncopleural ocorreu em 50,0% no pré-operatório e 46,2% após a cirurgia. O tempo total de internação hospitalar foi, em média, de 27,52 dias e tempo pós-operatório com média de 12,60 dias. Complicações pós-operatórias ocorreram em 13 crianças e não houve mortalidade. Conclusões: Propõe-se abordagem cirúrgica nos pacientes sem resposta ao tratamento clínico, pois o atraso na intervenção cirúrgica associa-se a infecção progressiva no parênquima pulmonar e taxas maiores de complicações. A cirurgia pode conduzir a melhor evolução clínica e recuperação mais precoce.


ABSTRACT Objective: Necrotizing pneumonia (PNZ) is a severe and rare complication of a community-acquired pneumonia, affecting mainly children. We aimed to analyze medical records of children undergoing surgical treatment for PNZ and compare our results with those found in the medical literature. Methods: Retrospective analysis of children's medical charts who underwent an operation for PNZ, between July 2006 and July 2016, in two hospitals in southern Santa Catarina, Brazil. Results: A total of 26 children with a median age of 2.70 years and mostly females (61.5%) were included in the current study. The main symptoms were fever (88.5%) and cough (65.4%). There was an average use of 4.31 antibiotics per patient. The primary etiological agent was Staphylococcus aureus (23.1%), but cultures were negative in 69% of the patients. Decortication and debridement of necrotic areas were performed in 23 patients (88.5%). The mean postoperative pleural drainage was 8.12 days. The presence of bronchopleural fistula occurred in 50.0% in the preoperative period and 46.2% in the postoperative. The total length of hospital stay was, on average, 27.52 days and the postoperative length of stay was 12.60 days (mean). Postoperative complications occurred in 13 children and there was no mortality. Conclusion: The surgical approach is indicated to patients with no response to clinical treatment. Late surgical intervention is associated with progressive parenchyma infection and higher rates of complications. Surgery can lead to better clinical outcomes and earlier recovery.

ABSTRACT

ABSTRACT Background: Papiliotrema laurentii is one of several non-neoformans cryptococci that have rarely been associated with human infection, since it was previously considered saprophyte and thought to be non-pathogenic to humans. Nevertheless, increasing number of reports of human infection have emerged in recent years, mostly in oncologic patients. Aim: To report a case of a female patient with pyloric obstructive cancer with a catheter-related Papiliotrema laurentii blood stream infection and systematically review the available evidence on P. laurentii infection in humans. Methods: Retrieval of studies was based on Medical Subject Headings and Health Sciences Descriptors, which were combined using Boolean operators. Searches were run on the electronic databases Scopus, Web of Science, MEDLINE (PubMed), BIREME (Biblioteca Regional de Medicina), LILACS (Latin American and Caribbean Health Sciences Literature), Cochrane Library for Systematic Reviews and Opengray.eu. There was no language or date of publication restrictions. The reference lists of the studies retrieved were searched manually. Results: The search strategy retrieved 1703 references. In the final analysis, 31 references were included, with the description of 35 cases. Every patient but one had a previous co-morbidity - 48.4 % of patients had a neoplasm. Amphotericin B was the most used treatment and only a single case of resistance to it was reported. Most patients were cured of the infection. Conclusion: P. laurentii infection in humans is usually associated to neoplasia and multiple co-morbidities, and amphotericin B seems to be a reliable agent for treatment.

Resumo Objetivo: A blefarite é uma das condições mais comumente encontradas na prática oftalmológica e se constitui em uma causa frequente de irritação e desconforto ocular. Por ser uma doença de difícil tratamento, os autores buscaram compreender melhor a epidemiologia, etiologia, apresentações clínicas, tratamento e evolução de seus pacientes, visando maior sucesso terapêutico. Métodos: Foram avaliados retrospectivamente e transversalmente o prontuário de 124 pacientes do Centro de Oftalmologia Tadeu Cvintal, os quais apresentavam blefarite e foram submetidos à classificação de gravidade e coleta de secreções palpebrais para cultura bacteriana e antibiograma. Resultados: A media da idade dos pacientes foi de 67,4 anos, o sexo feminino foi responsável por 70 (56,4%) casos e o masculino por 54 (43,5%). Quanto à gravidade da doença, constatou-se 71 casos de blefarite leve (56,8%), 52 (41,6%) com intensidade moderada e 2 (1,6%) casos graves. Avaliando o seguimento do tratamento da doença, foi observado que 103 (82,4%) pacientes não retornaram para avaliar o resultado do tratamento e apenas 22 (17,6%) retornaram. Em relação às culturas realizadas, 82 (66,1%) não apresentaram crescimento microbiano. Dentre as 42 (33,8%) amostras positivas, os Staphylococcus coagulase negativo foram os mais prevalentes, sobretudo os Staphylococcus epidermidis, responsável por 35 (83,3%) delas. Quanto à sensibilidade aos antibióticos, os agentes de nossa amostra demonstraram maior resistência à Penicilina, Eritromicina e Ciprofloxacino e 100% de sensibilidade à Linezolida, Vancomicina e Daptomicina. Conclusão: Conhecendo melhor as características epidemiológicas da blefarite e a sensibilidade antimicrobiana das bactérias envolvidas, é possível oferecer tratamentos mais eficazes.


Abstract Objective: Blepharitis is one of the most commonly encountered conditions in ophthalmic practice and is a frequent cause of eye irritation and discomfort. Being a difficult to treat disease, the authors sought to better understand the epidemiology, etiology, clinical presentations, treatment and evolution of their patients, aiming at greater therapeutic success. Methods: The medical records of 124 patients of Centro de Oftalmologia Tadeu Cvintal who had blepharitis were retrospectively and cross-sectionally evaluated and underwent severity classification and collection of eyelid secretions for bacterial culture and antibiogram. Results: The mean age of the patients was 67.4 years, females accounted for 70 (56.4%) cases and males for 54 (43.5%). Regarding the severity of the disease, there were 71 cases of mild blepharitis (56.8%), 52 (41.6%) with moderate intensity and 2 (1.6%) severe cases. Evaluating the follow-up of treatment of the disease, it was observed that 103 (82.4%) patients did not return to evaluate the treatment outcome and only 22 (17.6%) returned. In respect of the cultures performed, 82 (66.1%) did not show microbial growth. Among the 42 (33.8%) positive samples, coagulase-negative staphylococci were the most prevalent, especially Staphylococcus epidermidis, responsible for 35 (83.3%) of them. As for antibiotic sensitivity, the agents in our sample showed greater resistance to Penicillin, Erythromycin and Ciprofloxacin and 100% sensitivity to Linezolid, Vancomycin and Daptomycin. Conclusion: By better understanding the epidemiological characteristics of blepharitis and the antimicrobial sensitivity of the bacteria involved, it is possible to offer more effective treatments.

ABSTRACT

OBJETIVO: Analizar el uso de beta-lactámicos en sepsis neonatal tardía, en comparación con el tratamiento empírico actual con vancomicina, mediante la revisión de artículos científicos. METODOLOGÍA: Revisión temática en Bases LILACS y PubMed. La selección de los artículos se realizó mediante la lectura de título, abstract y texto completo. Criterios de búsqueda: Estudios en humanos, artículos por abstract y texto completo, en inglés y español, y de no más de 10 años. RESULTADOS: No hay relación en la duración ni en la mortalidad de la sepsis al utilizar un betalactámico, o al utilizar vancomicina. Además, cepas resistentes a beta-lactámico, respondieron bien al usar un beta-lactámico como terapia empírica inicial, sin la necesidad de recurrir a vancomicina, excepto en casos de no mejoría clínica. CONCLUSIONES: Beta-lactámicos pueden ser utilizados como terapia empírica inicial en sepsis neonatal tardía como alternativa al tratamiento actual con vancomicina, restringiendo el uso de vancomicina a casos de resistencia, o cuando no haya mejoría clínica del recién nacido que está utilizando un beta-lactámico como tratamiento.


OBJECTIVE: To analyze the use of beta-lactams in late- onset neonatal sepsis, compared with empirical treatment with vancomycin used currently, through the revision of scientific articles. METHODOLOGY: Thematic review in LILACS and PubMed. The articles were selected by reading the title, abstract and full text. Searching criteria: Human studies, articles by abstract and full text, in English and Spanish, and no more than 10 years since published. RESULTS: There is no relationship in duration or mortality in Sepsis when using beta-lactam, or using vancomycin. In addition, resistant strains to beta-lactam responded well in using betalactam as initial empirical therapy, without the need to resort to vancomycin, except in cases of non-clinical improvement. CONCLUSIONS: Beta-lactams may be used as initial empirical therapy in late-onset neonatal sepsis as an alternative to current vancomycin therapy, restricting the use of vancomycin to resistance cases, or when there is no clinical improvement in the neonate, who is using a beta-lactam as a treatment.

ABSTRACT

Resumen Introducción: La piomiositis es la infección del músculo esquelético, entidad poco frecuente en pediatría. Objetivo: Describir las características de 21 niños con piomiositis. Métodos: Estudio prospectivo-analítico de niños ingresados con diagnóstico de piomiositis entre mayo de 2016 y abril de 2017 en el Hospital de Niños Ricardo Gutiérrez, Buenos Aires, Argentina. Resultados: Tasa de hospitalización de 21,5/10.000 admisiones (IC 95% 4,65- 71,43). La mediana de edad fue de 5,4 años (rango 1,25-11,6). El 90,4% presentaba algún factor predisponente. La localización más frecuente fue en miembros inferiores. La proteína C reactiva (PCR) estuvo elevada en todos los pacientes, con una media de 124 mg/L (DS 96), siendo significativamente más elevada en los pacientes que tuvieron hemocultivos positivos 206 (DS 101) vs 98 (DS 81), (p = 0,02). Se obtuvo rescate microbiológico en 17 pacientes (80,9%): Staphylococcus aureus resistente a meticilina (SARM) (n: 15) y Streptococcus pyogenes (n: 2). Se presentó con bacteriemia 23,8% de los pacientes. El 81% requirió drenaje quirúrgico. Conclusión: Staphylococcus aureus RM adquirido en la comunidad (SARMAC) es el patógeno predominante. En la selección del tratamiento empírico adecuado debería tenerse en cuenta: el patrón de resistencia local y el valor de PCR.


Background: Pyomyositis is the infection of skeletal muscle, a rare pathology in children. Aim To describe the characteristics of pyomyositis in pediatric patients. Methods: Prospective analytical study of hospitalized children diagnosed with pyomyositis from May 2016 to April 2017 at the Ricardo Gutiérrez Children's Hospital, Buenos Aires, Argentina. Results: Twenty-one patients with pyomyositis were identified. Annual rate: 21.5/10,000 admissions (95% CI 4.65-71.43). The median age was 5.4 years (range 1.25-11.6). The lower limbs were the most affected site. C-reactive protein (CRP) was elevated in all patients, with a mean of 124 mg/L (SD 96), being significantly higher in patients with bacteremia: 206 (DS 101) vs 98 (DS 81), p = 0.02. Bacterial cultures were positive in 17/21 (80.9%): 15 methicillin-resistant Staphylococcus aureus (MRSA), and 2 Streptococcus pyogenes. Blood cultures were positive in 5 (23.8%). Conclusion: MRSA-community acquired is the predominant pathogen in our setting. In the selection of the appropriate empirical treatment, the local resistance pattern and the CRP value should be taken into account.

ABSTRACT

Introducción: La parotiditis supurativa aguda se presenta con poca frecuencia en el período neonatal. Objetivo: Aportar un nuevo caso de parotiditis supurativa aguda por Staphylococcus aureus resistente a la Meticillina. Presentación del caso: El presente caso tiene la particularidad de que presentó foco de infección inicial (impétigo y conjuntamente mastitis bilateral), en el que se demostró el mismo microorganismo causal de la infección: Staphylococcus aureus resistente a la Meticillina. La mastitis bilateral evolucionó hacia la formación de absceso. En la literatura revisada solo se encontraron tres publicaciones que tratan de neonatos con un foco inicial de infección en sitios diferentes de la parotiditis. Estos aspectos fueron los que motivaron la presentación del caso. Conclusiones: Staphylococcus aureus resistente a la Meticillina ha emergido en los últimos años como agente causal de parotiditis supurativa aguda, que puede diseminarse hacia otro foco infeccioso, habitualmente se logra la curación con tratamiento antibiótico ajustado al agente causal, concretamente con Vancomicina, aunque puede requerir también tratamiento quirúrgico si ocurre abscedación(AU)


Introduction: Acute suppurative parotitis occurs infrequently in the neonatal period. Objective: To provide information of a new case of acute suppurative parotitis caused by Methicillin- resistant Staphylococcus aureus. Case presentation: The present case has the particularity that the patient presented a source of initial infection (impetigo and jointly bilateral mastitis), in which the same causal microorganism of the infection was found: Methicillin resistant Staphylococcus aureus. Bilateral mastitis evolved to the formation of abscess. In the literature reviewed, there were only 3 publications on neonates who presented an initial source of infection in sites different from parotitis. These aspects are those that motivated the presentation of this case. Conclusions: Methicillin resistant Staphylococcus aureus has emerged in the last years as a causal agent of acute suppurative parotitis that can lead to dissemination of another source of infection. Normally, the cure is achieved with antibiotic treatment adjusted to the causal microorganism, specifically with Vancomycin; although it can require surgical treatment if abscesses occurs(AU)

ABSTRACT

Abstract Vancomycin is a first-line drug for treating methicillin-resistant Staphylococcus aureus. Thrombocytopenia is a rare adverse reaction to vancomycin treatment, and there are no reports of vancomycin-induced thrombocytopenia (VIT) in infants. We describe the case of a 3-month-old girl who was diagnosed with purulent meningitis. After 13 days of treatment with vancomycin, her platelet count reduced to 8 × 109/L. Vancomycin was discontinued, and intravenous methylprednisolone was administered. The platelet count returned to normal after 4 days. Patients, especially young children, receiving vancomycin for a long clinical course should undergo careful monitoring of laboratory indicators and blood tests.

ABSTRACT

Introducción: La infección posquirúrgica en la columna lumbar es desafortunadamente común, multifactorial y una complicación potencialmente devastadora, que se asocia a un incremento de la morbilidad y la necesidad de futuras cirugías, y en última instancia, puede ser mortal. Con la intención de disminuir la morbilidad posquirúrgica, la medicación y los días de internación, comenzamos a utilizar aloinjerto fresco congelado de cabeza femoral de donantes vivos, en la artrodesis lumbar corta. El objetivo de este estudio fue comparar el índice de infección en la artrodesis lumbar corta en pacientes con aloinjerto fresco congelado y con autoinjerto. Materiales y Métodos: Estudio retrospectivo de 153 pacientes divididos en dos grupos: grupo A: 84 pacientes con autoinjerto de cresta ilíaca y grupo B: 69 pacientes con aloinjerto fresco congelado, desde marzo de 2009 hasta enero 2014, sometidos a cirugía instrumentada de fusión espinal lumbar posterolateral. Resultados: Tres de los 153 pacientes operados se perdieron en el seguimiento (2 del grupo A y 1 del grupo B) y la muestra incluyó 150 pacientes (82 del grupo A y 68 del grupo B). Se produjeron tres infecciones por Staphylococcus aureus sensible a la meticilina, todas en el grupo A (4,5%). Ningún paciente de los dos grupos necesitó transfusión. Conclusiones: El uso de aloinjerto fresco congelado en las cirugías de columna lumbar posterolateral de causa degenerativa no se asocia a un aumento en la tasa de infección. Consideramos que el aloinjerto fresco congelado es una excelente alternativa, porque disminuye el tiempo quirúrgico y de hospitalización. Nivel de Evidencia: III


Introduction: Postoperative infection in lumbar spine is unfortunately common, multifactorial and a potentially devastating complication that is associated with increased morbidity and the need for future surgery, being eventually fatal. To reduce postoperative morbidity, medication and hospital stay, we began to use fresh-frozen bone allograft of femoral head from living donors in short lumbar arthrodesis. The aim of the present study was to analyze the rate of infection in patients with short lumbar arthrodesis with fresh-frozen bone allograft versus bone autograft. Methods: Retrospective study in 153 patients divided into two groups: group A, 84 patients with iliac crest autograft and group B, 69 patients with fresh-frozen bone allograft, from March 2009 to January 2014, undergoing instrumented posterolateral lumbar spinal fusion surgery. Results: Three of the 153 operated patients were lost at follow-up (2 in group A and 1 in group B) leaving the sample with 150 patients (82 in group A and 68 in group B). There were three infections caused by methicillin-sensitive Staphylococcus aureus in group A (4.5%). No patient required transfusion. Conclusions: The use of fresh-frozen bone allograft in posterolateral lumbar spine surgeries for degenerative causes is not associated with an increase in the infection rate. We consider that fresh-frozen bone allograft is an excellent alternative, because it reduces surgical and hospitalization times. Level of Evidence: III

ABSTRACT

ABSTRACT Bloodstream and venous catheter-related corynebacterial infections in paediatric patients with haematological cancer were investigated from January 2003 to December 2014 at the Brazilian National Cancer Institute in Rio de Janeiro, Brazil. We observed that during cancer treatment, invasive corynebacterial infections occurred independent of certain factors, such as age and gender, underlying diseases and neutropenia. These infections were ssscaused by Corynebacterium amycolatum and other non-diphtherial corynebacteria. All cases presented a variable profile of susceptibility to antimicrobial agents, except to vancomycin. Targeted antibiotic therapy may contribute to catheters maintenance and support quality of treatment. Non-diphtherial corynebacteria must be recognized as agents associated with venous access infections. Our data highlight the need for the accurate identification of corynebacteria species, as well as antimicrobial susceptibility testing.
