RESUMO

RESUMEN Introducción: Las infecciones de las úlceras del pie diabético son comunes, complejas, de alto costo y constituyen la principal causa de amputación no traumática de las extremidades inferiores. Objetivo: Identificar los microorganismos aislados para estimar tanto la sensibilidad a los antibióticos como la coincidencia entre el tratamiento empírico y los resultados microbiológicos en pacientes con úlceras del pie diabético. Métodos: Se realizó una investigación descriptiva-retrospectiva. La población de estudio estuvo constituida por 210 pacientes ingresados en el Hospital Universitario Clínico Quirúrgico "Comandante Faustino Pérez Hernández" de Matanzas entre junio de 2017 y junio de 2020. Las variables de salida fueron la frecuencia y el tipo de germen, la cantidad de gérmenes por úlcera, la sensibilidad para cada tipo de antibiótico, y el porcentaje de coincidencia entre el tratamiento empírico y el resultado microbiológico. Resultados: Se identificaron 259 gérmenes y se observaron 1,23 gérmenes por úlcera. El 62,5 por ciento de los gérmenes encontrados fueron Gram negativos, pero el germen más representado fue el Staphylococcus aureus. El 58,8 por ciento de los Staphylococcus aureus se mostraron resistentes a la meticillin. La vancomicina y el linezolid resultaron efectivos en el 100 por ciento de los Gram positivos. La amikacina fue el antibiótico más efectivo para los Gram negativos. Se observó coincidencia entre el tratamiento empírico y el resultado del antibiograma en el 27,6 por ciento de los pacientes. Conclusiones: Resulta necesario un apropiado diagnóstico microbiológico de las úlceras del pie diabético para identificar los gérmenes presentes en las lesiones y diseñar algoritmos de terapia antimicrobiana adecuados(AU)

ABSTRACT Introduction: Diabetic foot ulcer infections are common, complex, high cost and are the leading cause of non-traumatic lower extremity amputation. Objective: To identify the microorganisms isolated to estimate both the sensitivity to antibiotics and the coincidence between empirical treatment and microbiological results in patients with diabetic foot ulcers. Methods: A descriptive-retrospective investigation was performed. The study population consisted of 210 patients admitted to the University Hospital "Comandante Faustino Pérez Hernández" of Matanzas between June 2017 and June 2020. The output variables were the frequency and type of germ, the number of germs per ulcer, the sensitivity for each type of antibiotic, and the percentage of coincidence between the empirical treatment and the microbiological result. Results: A total of 259 germs were identified and 1.23 germs per ulcer were observed. The 62.5 percent of the germs found were Gram negative, but the most represented germ was Staphylococcus aureus. Of the Staphylococcus aureus, 58.8 percentwere resistant to methicillin. Vancomycin and linezolid were effective in 100 percent of Gram positives. Amikacin was the most effective antibiotic for Gram-negatives. Agreement between empirical treatment and antibiogram result was observed in 27.6 percent of patients. Conclusions: An appropriate microbiological diagnosis of diabetic foot ulcers is necessary to identify the germs present in the lesions and to design adequate antimicrobial therapy algorithms(AU)

RESUMO

El tratamiento de las infecciones del tracto urinario requiere la constante actualización de la susceptibilidad in vitro de los gérmenes de la zona o institución que permita orientar la elección apropiada del tratamiento empírico. Objetivo: Identificar los factores de riesgo asociados a infecciones del tracto urinario por gérmenes productores de BLEE en pacientes hospitalizados en el Hospital Militar "Dr. Carlos Arvelo" con diagnóstico de infección del tracto urinario durante el periodo enero de 2015 y diciembre de 2019. Método: estudio retrospectivo, corte transversal, casos y controles. Tratamiento estadístico: Se calculó la razón de probabilidades de los factores de riesgo previamente establecidos. Los factores que demuestren asociación significativa en el análisis univariable serán incluidos en el modelo de regresión logística a fin de determinar los predictores independientes de infección por gérmenes productores BLEE. Resultados: Se evaluaron 283 pacientes, 161 con fenotipo de BLEE y 122 no BLEE. La edad mayor a 65 años (p =0,001; OR 1,059), infección del tracto urinario recurrente (p <0,001; OR 3,689), uso de antibióticos en los último 3 meses (p <0,001; OR 6,921), y sondaje vesical permanente mayor a 30 días (p <0,001; OR 6,801) fueron predictores independientes de ITU por bacterias productoras de BLEE. Conclusiones: Los factores de riesgo identificados en nuestro estudio ayudarán a guiar el reconocimiento de pacientes con alto riesgo de infección por estos organismos. Estos resultados sugieren la necesidad de revisión de los esquemas terapéuticos empíricos locales en el tratamiento de infecciones del tracto urinario, basándose en el riesgo de cada paciente(AU)

Urinary tract infections are an important cause of disease, its treatment requires the permanent update of in vitro antimicrobial susceptibility of the major germs of the institution to allow the appropriate choice of empirical treatment; Objective: To identify the risk factors associated with urinary tract infections caused by extended-spectrum beta-lactamases-producing germs in patients admitted at the Hospital Militar "Dr. Carlos Arvelo" with urinary tract infections between the january 2015 and december 2019. Methods: this is a retrospective study of a crosssectional cohort of cases and controls. Statistical Analysis: We also calculated adjusted odds ratios and 95% confidence intervals for target risk factors. Risk factors with significant association to ESBLs in the univariate analysis were included in a logistic regression model in order to determine independent forecasters of infections by ESBL-producing organisms. Results: Two hundred and eighty three patients were assessed: 161 with a phenotype of ESBL and 122 without ESBL. Ages over 65 years old (p =0,001; OR 1,059), regular urinary tract infection (p <0,001; OR 3,689), use of antibiotics in the last 3 months (p <0,001; OR 6,921), and permanent bladder catheterization for more than 30 days (p <0,001; OR 6,801) were independent forecasters of UTIs by ESBL-producing bacteria. Conclusions: the risk factors identified in our study will help guide the recognition of patients at high risk of infection by these organisms. These results suggest the need to review local empirical therapeutic schemes in the management of urinary tract infections, based on the odds of each patient of acquiring these bacteria(AU)

RESUMO

Objetivo: Evaluar la relevancia del uro y coprocultivo en la práctica clínica frecuente. Estrategia de búsqueda y selección de estudios: Se ha realizado una revisión bibliográfica en las bases de datos on-line Elsevier-Doyma y PubMed, de los artículos y guías de práctica clínica publicadas sobre este tema priorizando los trabajos realizados en América Latina. Selección de estudios y de datos: En la revisión se han incluido guías de la Sociedad Americana de Enfermedades Infecciosas (IDSA), manuales y guías de la Sociedad Española de Enfermedades Infecciosas, y los últimos artículos originales sobre este tema publicados en la región. Resultados: Escherichia coli continúa siendo el agente causal más frecuente tanto en urocultivo como en coprocultivo. En nuestro Hospital, han aumentado de forma importante las resistencias a antimicrobianos en especial a quinolonas. Conclusiones: La mayoría de los antibióticos utilizados como primera línea en la terapia empírica presentan elevados porcentajes de resistencias. En nuestro Hospital el antibiótico empírico de elección en infecciones urinarias fue levofloxacina en un 34,4% y ciprofloxacina en un 42%. En cuanto al coprocultivo la mayor resistencia presenta Eritromicina y Levofloxacina con 87,5%, seguido de Ampicilina con 76% de resistencia.

Abstract Aim: Evaluate the relevance of the urine culture and stool culture in common clinical practice. Search strategy and selection of studies: We performed a literature review on databases online Elsevier-Doyma and PubMed, articles and clinical practice guidelines published on this subject prioritizing work in Latin America. Study selection and data: The review included guides Infectious Diseases Society of America (IDSA), manuals and guides the Spanish Society of Infectious Diseases, and the last original published articles on this topic in the region. Results: Escherichia coli remains the most prevalent in both urine culture and coprocultivo causal agent. In our hospital, they have increased significantly the resistance to antibiotics especially quinolones. Conclusions: Most of the antibiotics used as first-line empiric therapy have high percentages of resistance. In our Hospital empirical antibiotic of choice in urinary tract infections was 34.4% levofloxacin and ciprofloxacin by 42%. Regarding coprocultivo presents greater resistance to erythromycin and Levofloxacin 87.5%, followed by 76% Ampicillin resistance

RESUMO

To review the bacteriological features of infectious spondylodiscitis and provide recommendations for the initial therapy which remains empirical in our context. Retrospective study including patients diagnosed with spondylodiscitis over a period of 4 years (2006-2009) at the Rabat Military Teaching Hospital. During the study period, we analysed 30 cases: the mean age was 49.9 years and 21 cases (70%) were male. The patients were predominantly hospitalized in neurosurgery department (15/30) followed by rheumatology department (10/30). The site of infection was lumbar in 21 cases (21/30), dorsal in 7 cases (7/30). 26 cultures were positive of which 19 (19/26) were monomicrobial. Tuberculosis (TB) was implicated in 10 cases (10/30) including 4 cases in association with common organisms (Propionibacterium acnes, Staphylococcus aureus, Staphylococcus epidermidis, Corynebacterium species). Brucella melitensis was isolated in 1 case. Infections caused by pyogenic bacteria were isolated in 15 cases of which 12 (12/15) revealed simple organisms including Gram-positive cocci in 9 cases (9/12) with 3 cases of S. aureus and Gram-negative bacilli in 3 cases (3/12) with 2 cases of P. aeruginosa. Blood cultures carried out for 16 patients were positive in 7 cases. The anatomopathologic exams carried out for 20 patients found in 6 cases epithelioid granulomata and giants cells with caseous necrosis in total concordance with TB culture. TB is the most frequent cause of spondylodiscitis in Morocco. Our study found the same frequency for non-specific and specific germs. Empirical treatment must take into account S. aureus and M. tuberculosis.

RESUMO

La Dacriocistitis Aguda (DA) consiste en una inflamación del saco lagrimal y conducto nasolagrimal, secundario a un proceso infeccioso mayoritariamente o a estenosis senil del conducto, traumatismos, tumores, sinusitis, conjuntivitis crónica y/o canaliculitis. Los grupos etarios más afectados son los lactantes y personas de edad avanzada, especialmente mujeres. Los agentes infecciosos más frecuentemente involucrados son Staphylococcus aureus y Streptococcus beta-hemolítico. Objetivos: Determinar la frecuencia de la patología, tiempo de hospitalización, la distribución por edad, la prevalencia por sexo de esta patología, tipo de tratamiento recibido por los pacientes. Metodología: los datos requeridos para el estudio se obtuvieron de la revisión de los antecedentes de hospitalización y de las fichas clínicas. Resultados: En un total de 1.870 hospitalizaciones oftalmológicas efectuadas entre Junio y Diciembre de 2007, 102 fueron por DA (5,5 por ciento). El 78 por ciento de estos era de sexo femenino y el mayor número de consultas se dieron en personas con edades entre los 70 y 79 años (33.3 por ciento). El 52.9 por ciento de los casos necesitó solo un día de hospitalización, recibiendo tratamiento sistémico el 15,7 por ciento de los pacientes que presentaba complicaciones o reagudización del cuadro. Conclusiones: El porcentaje de hospitalizaciones por DA constituye el 5,5 por ciento del total de hospitalizaciones por patologías oculares, la cual se manifiesta mayormente en mujeres adultas mayores, con hospitalizaciones de un día y antibióticoterapia sistémica efectuada con cloxacilina.

Acute dacryocystitis is an inflammation of the lacrimal sac and nasolacrimal duct, mostly secondary infection process, or senile duct stenosis, trauma, tumors, sinusitis, or chronic conjunctivitis and canaliculitis. The age groups most affected are infants and elderly, especially women. Infectious agents most commonly involved are Staphylococcus aureus and Streptococcus beta-hemolytic. There are no epidemiological studies or history of national and local causative of this condition. Objectives: To determine the frequency of hospitalization, the age distribution by sex and prevalence of this disease, know the length of hospital employee and the treatment received by patients Methodology: The data required for the study was obtained from a review of clinical records of patients Results. A total of 1870 hospitalizations eye made between June and Oecember 2007, 102 were for dacryocystitis (55 percent). 78 percent of patients were female and the largest number of inquiries occurred in patients aged 70 to 79 years (33.3 percent) The 52.9 percent of cases needed only one day of hospitalization, receiving systemic treatment for 15.7 percent of patients had complications or exacerbation of the clinical, being the drug of choice, cloxacillin. Conclusions: The incidence of hospitalizations for acute dacryocystitis is 5.5 percent of total hospitalizations for ocular pathologies. Oacryocystitis occurs mostly in older adults, whose age ranges are between 60 and 89 years, mostly female. The hospitalization time required is not more than one day to prepare for surgery, for the treatment of infectious event is performed as an outpatient. Systemic antibiotic therapy conducted in patients who show no response to empiric therapy is cloxacillin.
