Abscesos renales: experiencia en un hospital pediátrico de referencia / Renal abscesses: Experience at a referent Pediatric Hospital

INTRODUCCIÓN: El absceso renal es infrecuente en pediatría, con clínica y laboratorio inespecíficos. Ante su sospecha, es necesario realizar imágenes para establecer diagnóstico. Objetivo: Describir las características clínico-epidemiológicas, microbiológicas, diagnósticas y terapéuticas de abscesos renales en pediatría. PACIENTES Y MÉTODOS: Estudio retrospectivo, descriptivo, de pacientes internados con absceso renal, en seguimiento por Infectología del Hospital de Niños Ricardo Gutiérrez, durante 9 años. RESULTADOS: 15 pacientes (67% varones), mediana de edad 9 años (rango [r] 0,7-17). Cuatro pacientes con comorbilidades. El síntoma más frecuente fue fiebre seguido por dolor lumbar. El recuento medio de leucocitos en sangre fue de 15.700/mm3 (r: 7.100-45.000) y la PCR de 193 mg/L (r: 1-362). Cuatro pacientes presentaron urocultivo positivo: dos Escherichia coli, uno Klebsiella pneumoniae y E. coli y otro Candida albicans y K. pneumoniae. Ningún paciente presentó bacteriemia. El diagnóstico se confirmó por ecografía. Se realizó drenaje en siete pacientes, con aislamiento de Staphylococcus aureus en dos y Pseudomonas aeruginosa en uno. El tratamiento incluyó terapia combinada en 67%. Mediana de antibioterapia intravenosa fue 16 días (r: 7-49), total de 28 (r: 14-91). Un paciente requirió terapia intensiva y dos, nefrectomía. CONCLUSIÓN: Los abscesos renales son infrecuentes, con gran morbimortalidad. Sospechar en paciente con infección del tracto urinario (ITU) de evolución tórpida que persiste febril. En nuestro estudio, la alta sensibilidad de la ecografía renal permitió su diagnóstico precoz.

BACKGROUND: Renal abscesses are infrequent in pediatrics, with nonspecific clinical and laboratory findings. When suspected, imaging is essential to establish the diagnosis. Aim: To describe the clinical-epidemiological, microbiological, diagnostic and therapeutic characteristics of renal abscesses in pediatrics. METHODS: Retrospective and descriptive study of hospitalized patients with renal abscess, followed by Infectious Diseases Department of Ricardo Gutiérrez Children's Hospital during 9 years. Statistical analysis: Epi Info 7.2.2.6. RESULTS: 15 patients (67% male), median age 9 years (range [r] 0.7-17) were included. Four patients had underlying disease. The most frequent symptom was fever, with a median duration of 10 days (r:1-36), followed by lumbar pain. The median white blood cell count was 15,700/mm3 (r: 7,100-45,000) and CRP 193mg/L (r: 1-362). Four patients presented positive urine culture: 2 Escherichia coli, 1 Klebsiella pneumoniae and E. coli and 1 Candida albicans and K. pneumoniae. No patient had bacteremia. The diagnosis of abscess was confirmed by ultrasound. Surgical drainage was performed in 7 patients, with isolation of Staphylococcus aureus in 2 and Pseudomonas aeruginosa in 1. Empirical treatment included 3rd generation cephalosporin, combined in 67% of cases. The median of intravenous antibiotic therapy was 16 days (r: 7-49) with a total of 28 days (r:14-91). One patient required transfer to intensive care unit and 2 nephrectomy. CONCLUSION: Renal abscesses are infrecuent in pediatrics, but they present significant morbidity and mortality. It should be suspected in patients with urinary tract infection (UTI)with torpid evolution that persists with fever without antibiotic response. In our study, the high sensitivity of renal ultrasound allowed early diagnosis.

Incidencia de complicaciones post quirúrgicas en cirugía bucal / Incidence of post-surgical complications in oral surgery

OBJETIVO: El objetivo principal de este estudio fue determinar la incidencia de complicaciones post cirugía bucal. METODOLOGÍA: Se desarrolló un estudio observacional, descriptivo, con el uso del registro prospectivo de la totalidad de pacientes ingresados para cirugía bucal del Complejo Hospitalario San Borja-Arriarán durante doce meses de observación (abril 2017 a marzo 2018). RESULTADOS: La muestra estuvo conformada por 532 pacientes sometidos a procedimientos quirúrgicos de cirugía bucal y 29 casos de complicación postquirúrgica. La incidencia de complicaciones alcanzó un 5,5% y se observó de manera predominante en intervenciones de tipo exodoncia. La complicación mayormente observada fue la alveolitis alcanzando un 2,5% de las cirugías de terceros molares y un 3,7% de las exodoncias de otros dientes. Las hemorragias postoperatorias se observaron en un 1,1% de las cirugías de terceros molares. Otras complicaciones postquirúrgicas fueron abscesos de espacios faciales, parestesia del nervio alveolar inferior, hematomas, equimosis y periostitis. CONCLUSIÓN: Los resultados fueron similares a los reportados en la literatura tanto en su frecuencia como en el tipo de complicación.

OBJECTIVE: The main objective of this investigation was to determine the incidence of postoperative complications in oral surgery. MATERIALS AND METHODS: An observational and descriptive study was developed with the use of the prospective registry of the patients admitted for oral surgery in the San Borja Arriarán Hospital Complex for a twelve-month period of observation (April 2017 to March 2018). RESULTS: The sample consisted of 532 patients undergoing surgical procedures of oral surgery and 29 cases of postoperative complications. The incidence of complications reached 5,5% and it was observed predominantly in interventions of tooth extraction. The most commonly observed complication was dry socket, reaching 2,5% of third molar surgeries and 3,7% of extractions of other teeth. Postoperative hemorrhages were observed in 1,1% of third molar surgeries. Other postoperative complications were facial spaces abscesses, paresthesia of the inferior alveolar nerve, bruising, ecchymosis and periostitis. CONCLUSIONS: The results were similar to those reported in the literature both in their frequency and in the type of complication.

Epidemiology and outcomes of anal abscess in patients on chronic dialysis: a 14-year retrospective study

OBJECTIVES: We conducted this retrospective study to elucidate the clinical presentation and outcomes of anal abscess in chronic dialysis patients. METHODS: We performed a chart review of patients who were hospitalized for anal abscess from Jan. 2002 to Dec. 2015. A total of 3,074 episodes of anal abscess were identified. Of these, 43 chronic dialysis patients with first-time anal abscess were enrolled. Patients were divided into a surgical group and a nonsurgical group according to the treatment received during hospitalization. The baseline characteristics, clinical findings, treatments and outcomes were obtained and analyzed. The endpoints of this study were in-hospital mortality, one-year mortality and one-year recurrence. RESULTS: Of the 43 patients, 27 (62.7%) received surgical treatment, and 16 (37.2%) received antibiotic treatment alone. There was no significant difference in age, sex, body mass index, smoking habits, comorbidities, or dialysis characteristics between the two groups. Perianal abscess was the most common type of anal abscess, and 39.5% of patients experienced fistula formation. Most patients had mixed aerobic and anaerobic flora. Our data demonstrate that there was no significant difference in hospital stay, one-year survival or recurrence rate between the surgical group and nonsurgical group. However, there was a trend toward better in-hospital survival in patients who received surgical treatment (p=0.082). CONCLUSION: In chronic dialysis patients with anal abscess, there was no statistically significant difference in clinical presentation and outcomes between the surgical and nonsurgical groups, although the surgical group had a trend of better in-hospital survival.

Nem todo abscesso em pequenos ruminantes é causado por Corynebacterium pseudotuberculosis / Not all abscesses in small ruminants are caused by Corynebacterium pseudotuberculosis

O presente estudo objetivou determinar a prevalência e distribuição de lesões abscedativas, identificação do agente etiológico e avaliação das lesões histológicas em caprinos e ovinos abatidos em um matadouro-frigorífico com Serviço de Inspeção Federal do estado da Bahia.

The macroscopic and histological lesions of abscesses collected presented no difference between isolated microorganisms.(AU)

Perianal abscess: a descriptive analysis of cases treated at the Hospital Santa Marcelina, São Paulo / Abscesso perianal: análise descritiva de casos atendidos no Hospital Santa Marcelina, São Paulo

Abstract Introduction Perianal suppurations have an incidence of 1-2:10,000 inhabitants per year and represent about 5% of proctology consultations, more frequently in males, being rare in childhood. Although perianal or anorectal abscess is an entity of relatively simple diagnosis and treatment, in a considerable percentage of patients difficulties will be found, especially considering that the initial treatment of these patients is performed by non-specialist physicians. Objective This is a retrospective survey of cases of perianal and anorectal abscess operated in Santa Marcelina Hospital between October 2011 and December 2014. Patients and methods A retrospective study of patients operated on an emergency basis for perianal and/or anorectal abscess in Santa Marcelina Hospital between October 2011 and December 2014, being excluded patients with inflammatory bowel disease. Data of gender, age, clinical presentation, the season of the year in which the abscess occurred, time of progression of symptoms, comorbidities, signs of Systemic Inflammatory Response Syndrome (SIRS) on admission, surgeries carried out, reoperations and clinical outcome were analyzed. Results Electronic medical records of 52 patients (73.1% male) who underwent surgical treatment of anorectal and perianal abscess were analyzed. The mean overall age was 43.03 years, and all patients reported pain as the main symptom, with a mean time of symptoms of 6.5 days. As for the season of the year of onset and diagnosis of perianal abscess, 61.5% of patients had this pathology in the summer and spring months. Conclusion In our study, it can be observed a higher incidence of perianal abscess in males and in the warmer months; furthermore, just over half of the patients developed perianal fistula in their progression.

Resumo Introdução As supurações perianais apresentam uma incidência de 1-2:10000 habitantes por ano e representam cerca de 5% das consultas proctológicas, com maior frequência no sexo masculino, sendo raras na infância. Embora o abscesso perianal ou anorretal seja de diagnóstico e tratamento relativamente simples, uma percentagem considerável representa maior dificuldade para tal, notadamente pelo fato do atendimento inicial desses pacientes ser realizado por médicos não especialistas. Objetivo Levantamento retrospectivo dos casos de abscesso perianal e anorretal operados no Hospital Santa Marcelina entre outubro de 2011 e dezembro de 2014. Casuística e método Estudo retrospectivo de pacientes operados em caráter de urgência por abscesso perianal e/ou anorretal no Hospital Santa Marcelina entre outubro de 2011 e dezembro de 2014, excluídos portadores de doença inflamatória intestinal. Analisaram-se dados de sexo, idade, quadro clínico, época do ano da ocorrência do abscesso, tempo de evolução dos sintomas, comorbidades, sinais de Síndrome da Resposta Inflamatória Sistêmica (SIRS) na admissão, cirurgias realizadas, reoperações e desfecho clínico. Resultados Foram analisados prontuários eletrônicos de 52 pacientes submetidos à tratamento cirúrgico de abscesso anorretal e perianal, dos quais 73,1% pertenciam ao sexo masculino. A média de idade geral foi de 43,03 anos e todos os pacientes relataram dor como sintoma principal com média de tempo de sintomatologia de 6,5 dias. Quanto à época do ano do aparecimento e diagnóstico do abscesso perianal, 61,5% dos pacientes apresentaram a patologia nos meses de verão e primavera. Conclusão Em nosso trabalho, pode-se observar maior incidência de abscesso perianal no sexo masculino e nos meses mais quentes e que pouco mais da metade dos pacientes desenvolveram fístula perianal na evolução.

Extrapulmonary multidrug resistant tuberculosis presenting as chest wall abscess - A rare case report.

Summary: Even though the prevalence of pulmonary drug resistant tuberculosis is showing an increasing trend globally, only a few case reports of extrapulmonary tuberculosis caused by drug resistant mycobacteria have been documented over the last decade. Extrapulmonary tuberculosis is not infrequent and may cause considerable morbidity and mortality. Tuberculous abscess over chest wall is commonly due to the spread from an adjacent affected lymph node group. Multidrug resistance poses a great challenge to the physicians in managing such a condition and significantly affects the prognosis. Here we report a rare presentation of multidrug resistant tuberculosis as anterior chest wall abscess in a young male.

Clinical versus computed tomography evaluation in the diagnosis and management of deep neck infection

CONTEXTO: Infecções profundas do pescoço têm um potencial alto para complicações graves e morte, se não corretamente diagnosticadas e tratadas. A diferença entre resultados de avaliação clínica e tomográfica pode demonstrar que a avaliação clínica isolada subestima a extensão de doença, o que pode conduzir a tratamento conservador e a pior prognóstico. OBJETIVO: Comparar achados clínicos à tomografia computadorizada de pescoço em relação aos espaços cervicais envolvidos e determinar as características clínicas e radiológicas principais associadas com infecção de espaço profundo de pescoço. TIPO DE ESTUDO: Estudo retrospectivo não randomizado. LOCAL: Departamento de Otorrinolaringologia - Cabeça e Pescoço, Universidade Estatal de Campinas, Brasil, um centro universitário, terciário. MÉTODOS: Foi avaliado prontuário médico de 65 pacientes com infecções profundas de pescoço. Foram analisados idade, gênero, queixas clínicas, exames físicos, resultados de raios-x e tomografia computadorizada, microbiologia, tratamento e resultados. Foram avaliados os sinais clínicos e sintomas, estratificados em ordem de freqüência. A freqüência de espaços cervicais profundos envolvidos nesta infecção também foram avaliados clínico e tomograficamente. Todos resultados clínicos e tomográficos foram comparados com a observação cirúrgica em relação aos espaços cervicais afetados por infecção. RESULTADOS: Os resultados clínicos mais freqüentes foram inchaço cervical, dor local, eritema cutâneo local e aumento localizado de temperatura. O local mais afetado de acordo com a avaliação física foi o triângulo de submandibular (49,2%), mas, à tomografia computadorizada cervical, foi o espaço látero-faríngeo (65%). Mais de um espaço cervical profundo foi acometido, de acordo com a tomografia computadorizada cervical, em 90% dos pacientes, como demonstrado pela extensão do edema e aumento de captação de tecidos moles, e em geral apenas um espaço à avaliação clínica isolada. DISCUSSAO: Os sintomas clínicos mais freqüentes das infecções cervicais profundas foram dor cervical, aumento de volume cervical e febre. Sinais importantes da tomografia computadorizada, para avaliação desta infecção, foram aumento de captação de contraste em tecidos moles do pescoço e edema. O espaço profundo do pescoço mais afetado pela infecção foi o laterofaríngeo, pela tomografia computadorizada do pescoço. O espaço...

Splenic abscess: clinical features, microbiologic finding, treatment and outcome.

Splenic abscess is a rare clinical entity but may be underreported. A retrospective study at Srinagarind Hospital revealed 60 cases of splenic abscess between 1992 and 2001. The causative organisms were identified in 41 cases (68.3%). Gram negative bacilli were commonly isolated and Burkholderia pseudomallei was the most predominant. Diabetes mellitus and leukemia were common underlying diseases found in 46.3 per cent and 9.7 per cent of culture confirmed cases, respectively. The patients usually presented with fever, left upper quadrant pain, tenderness and splenomegaly. Multiple abscesses were more commonly found in the melioidosis than in the non-melioidosis group (p = 0.032), but a single abscess was more commonly found in the non-melioidosis than in the melioidosis group (p = 0.032). Concurrent liver abscesses, often multiple, were not different in both groups. Antimicrobials alone were given in 66.7 per cent of cases with melioidosis and 64.7 per cent of non-melioidosis group. Splenectomy and percutaneous aspiration were performed only in 29.3 per cent and 4.9 per cent of cases with splenic abscess. The overall mortality rate of splenic abscess was only 4.9 per cent in the present series. In conclusion, splenic abscess is not uncommon. Burkholderia pseudomalleli is the most common causative agent found in the present series. Therefore, it should be targeted in the initial empirical antibiotic therapy before the culture results are available especially when multiple lesions in the spleen and concurrent multiple liver abscesses are seen. Prolonged treatment with appropriate antimicrobials alone is usually effective. Splenectomy and/or aspiration may be useful in selected patients.

Perivalvular abscesses due to Staphylococcus aureus endocarditis comparison with Streptococcus viridans endocarditis and incremental value of transesophageal echocardiography.

BACKGROUND: Perivalvular abscesses are major complications of infective endocarditis (IE). The prevalence and best approach to detection of this complication in Staphylococcus aureus (SA) in comparison to Streptococcus viridans (SV) IE is unclear. METHOD: Among 243 consecutive episodes of IE diagnosed using the Duke criteria, who underwent either transthoracic (TTE) or transesophageal echocardiography (TEE) at the Mayo Clinic between 1988 and 1993, there were 64 cases of SV and 61 of SA IE. Comparison of TTE and TEE detection of abscesses were restricted to patients with either surgical or autopsy examination and both TTE and TEE were performed. RESULTS: Prosthetic valve and valve repair were significantly higher in SA compared to SV IE (46 vs 23%, P = 0.008). The prevalence of abscesses was higher in SA compared to SV IE (42 vs 14%, P = 0.08). 1 (10%) of abscess detected by TTE in SA compared to 1 (50%) in SV IE and 6 (60%) by TEE in SA and 1 (50%) in SV IE. Incremental value of TEE vs TTE was higher in SA 5/24 (21%) than in SV IE 0/14 (0%) P = 0.067. Hospital mortality was significantly higher in SA than SV IE (13 vs 2%, P = 0.013). CONCLUSION: Patients diagnosed with IE and those with SA 1) presented more often with prosthetic valve IE, 2) developed more perivalvular abscesses, and 3) had a higher in hospital mortality than those with SV. Incremental value of TEE was higher in SA than in SV IE, 4) therefore, had a stringent requirement for initial and repeated TEE to detect this ominous complication of IE.

Abscesos renales y perinefríticos / Renal and perinephritic abscess

Se efectúa un análisis retrospectivo de las características de 28 pacientes operados por Absceso Renal y/o Perinefrítico en el Servicio de Urología Dr. Sótero del Río, entre Enero de 1988 y Septiembre de 1994, en relación a la frecuencia del cuadro, los métodos diagnósticos, la bacteriología y el tratamiento efectuado a éstos pacientes. Destaca la contribución al diagnóstico de la Ecotomografía de urgencia y la presencia de bacterias anaeróbicos en el 15 por ciento de los casos. Se reporta una frecuencia de ingreso de 0.3 pacientes por mes por año y de 0.011 por ciento del total de ingresos hospitalarios. Cifra similar a la publicada en la literatura, con una mortalidad de 3.5 por ciento y 17.8 por ciento de nefrectomías

Absceso Tuboovárico. Estudio retrospectivo / Tubo-ovarian abscess. Retrospective study

Se realizó un estudio retrospectivo sobre 75 casos de absceso tuboovárico (ATO) atendidos en el Hospital Nacional Cayetano Heredia de Lima, Perú, durante el período de 1981-1990, con el fin de determinar los factores de riesgo, cuadro clínico, los procedimientos diagnósticos utilizados y evaluar el manejo junuto con las complicaciones que de él se derivan. Se encontró que la la frecuencia de ATO en el este hospital fue de 1.3 por ciento. Además, el ATO ocurre con mayor frecuencia en mujeres entre la tercera y la cuarta décadas de la vida, nulíparas y con actividad sexual. El ATO ocurre independientemente del uso de dispositivo intrauterino. Otro hallazgo fue que los signos y síntomas de presentación más frecuentes del cuadro clínico del ATO son el dolor abdominal bajo o pélvico (98.63 por ciento), presencia de masa anexial (94.52 por ciento) y el dolor a la movilización cervical (73.97 por ciento) asociados a fiebre y taquicardia en 87.38 por ciento. La leucocitosis con desviación izquierda estuvo presente en 50.68 por ciento de los casos. La ecografía (realizada en 27 casos) fue positiva en el 74.07 por ciento y negativa en 25.93 por ciento, la laparoscopía (realizada en 6 casos) fue positiva en 83.33 por ciento y negativa en 16.67 por ciento. La culdocentesis (realizada en 39 casos) fue positiva en 84.61 por ciento y negativa en 15.39 por ciento. El 76.72 por ciento de los casos correspondioeron a ATO no roto, de los cuales el 21.43 por ciento recibieron tratamiento médico conservador y 78.57 por ciento recibieron tratamiento quirúrgico, de éstos el 75 por ciento fueron sometidos a histerectomía con anexectomía y 25 por ciento a anexectomía. El 23.28 por ciento de los casos fueron ATO roto, practicándose histerectomía con anexectomía en 88.24 por ciento y anexectomía sola en 11.76 por ciento. No hubo mortalidad en nuestro estudio probablemente en relación al tratamiento médico y/o quirúrgicos inmediatos.
