ABSTRACT
La endocarditis infecciosa es un proceso inflamatorio infeccioso causado por distintos microorganismos afectando el endocardio. Es una entidad poco frecuente en niños previamente sanos; no obstante, no es rara su ocurrencia en niños con ciertas cardiopatías congénitas; encontrándose un aumento en la incidencia en los extremos de las edades pediátricas. Objetivo: Describir las características clínicas y epidemiológicas de los pacientes pediátricos hospitalizados en el Hospital Universitario de Caracas, durante el período comprendido entre enero 2001 a diciembre 2020. Metodología: Estudio descriptivo y retrospectivo, utilizando como criterio de inclusión todo paciente pediátrico entre 0-12 años que ingresa con el diagnóstico de endocarditis infecciosa. Se recolectaron datos como edad, sexo, nivel socioeconómico, comorbilidades, factores predisponentes, hallazgos clínicos, paraclínicos, ecocardiográficos y terapéutica indicada; analizándose con estadística descriptiva, con el fin de establecer tablas de distribución de frecuencias. Resultados: Se incluyeron 17 pacientes en el estudio; el género masculino, los recién nacidos y preescolares fueron los que desarrollaron mayormente esta patología, observándose una supervivencia del 70,8 %. El principal factor predisponente para su desarrollo fue la presencia de catéter venoso central. En el 42,9 % de los hemocultivos se aisló Candida spp. Conclusión: En endocarditis infecciosa, a pesar de su baja incidencia, las complicaciones y mortalidad pueden ser altas; por lo cual ante todo paciente portador de catéter venoso central, con clínica de fiebre, taquicardia y soplo cardíaco, con hallazgos paraclínicos de leucocitosis, anemia y elevación de reactantes de fase aguda se sugiere el descarte de la misma.
Infective endocarditis is an infectious inflammatory process caused by different microorganisms affecting the endocardium. It is a rare entity in previously healthy children; however, its occurrence in children with certain congenital heart diseases is not uncommon; finding an increase in incidence at the extremes of pediatric ages. Objective: To describe the clinical and epidemiological characteristics of pediatric patients hospitalized at the Hospital Universitario de Caracas, during the period from January 2001 to December 2020. Method: Descriptive and retrospective study, using as inclusion criteria all pediatric patients between 0-12 years of age who are admitted with the diagnosis of infective endocarditis. Data such as age, sex, socioeconomic level, comorbidities, predisposing factors, clinical, paraclinical, echocardiographic findings, and indicated therapy were collected; being analyzed with descriptive statistics, in order to establish frequency distribution tables. Results: 17 patients were included in the study, the male gender, the newborns and preschoolers were the ones who developed this pathology with survival of 70.8 %. The main predisposing factor for its development was the presence of central venous catheter. Candida spp was isolated in 42.9 % of blood cultures. Conclusion: In infective endocarditis, despite having low incidence, complications and mortality can be high; therefore, in all patients with a central venous catheter, with symptoms of fever, tachycardia and heart murmur, with paraclinical findings of leukocytosis, anemia and elevation of acute phase reactants, it is suggested to discard it.
ABSTRACT
Objectives:Antibiotics are frequently used in tertiary care hospitals. We conducted an observational study on chil-dren admitted to a teaching hospital in south India, to make a profile of antibiotics use and suspected adverse drug reactions (ADRs) owing to them. Methods:Hospitalized children of either sex, aged between 1 month and 12 years, were inspected. Baseline demographic and clinical features, duration of hospital stay, antibiotics received in hospital along with dosing and indications and interest of suspected ADRs attributable to their use were recorded. Every pa-tient was followed up till discharge, admission to the Pediatric Intensive Care Unit, or passing. Results:Over the year and a half report period 364 confirmations were screened. The prevalence of Antibiotics use was 80.22%. The majori-ty of the 292 children who received Antibiotics were males (63.35%). Median age was 35 months, five children died. In most instances, either two (41%) or a single antibiotic (37.32%) was used. Ceftriaxone, co-amoxiclav, amikacin, vancomycin, and ampicillin were predominantly used. Antimalarials, antivirals and antiprotozoals were used occa-sionally. Average number of Antibiotics per patient was 2.2± 1.1 the majority (81.15%) were by parenteral route and initial choice was usually empirical. Prescriptions were usually in generic name. The antibiotic treatment went some-where in the range of 1 and 32days, with a middle of 8 days. Five ADRs were noted of which half were skin rash and the rest loose stools. Conclusions:The profile of Antibiotic utilize is comprehensively like prior Indian investigations. Apparent overuse of multiple Antibiotics per prescription and the parenteral route requires exploration. Antibiotics are being used empirically in the absence of policy. ADRs to Antibiotics are occasional and usually mild. The bench-mark information can serve in situation analysis for antibiotic prescribing guidelines.
ABSTRACT
OBJETIVO: Descrever a variabilidade genotípica do rotavírus grupo A (RVA) encontrado em pacientes pediátricos imunocompetentes e imunocomprometidos tratados no Hospital de Clínicas/Universidade Federal do Paraná (HC/UFPR), Curitiba, Paraná. MÉTODOS: Foi realizado um estudo transversal com 1.140 amostras de fezes coletadas, de abril de 2001 a dezembro de 2008, em pacientes ambulatoriais e pacientes hospitalizados com gastroenterite aguda encaminhados ao hospital. As técnicas usadas foram o método da aglutinação do látex e imunoensaio enzimático para diagnóstico de RVA. Foi realizada transcrição reversa, seguida por PCR multiplex semi-nested e sequência de nucleotídeos para caracterização do genótipo. Foram relatados dados de combinações de genótipos, clínicos, epidemiológicos, laboratoriais e sobre a presença de infecções hospitalares. RESULTADOS: Foi analisado um total de 80 amostras de fezes positivas para rotavírus. As associações mais frequentes entre os genótipos G e P foram: G4 P[8] (38,9%), G1 P[8] (30,5%), G9 P[8] (13,9%), G2 P[4] (6.9 %) e G3 P[8] 1,4%). O genótipo prevalente foi G2 P[4] depois da implementação da vacina nos anos de 2006 e 2008. Verificou-se que um total de 62,5% das crianças com idade abaixo de 12 meses estavam infectadas. Destas, 55,6% tinham grave desidratação, e 26,7% precisaram de cuidados intensivos. Encontrou-se uma frequência de 12,5% de infecções hospitalares. Não se observou correlação entre o genótipo e a gravidade da infecção nos pacientes estudados. CONCLUSÃO: As infecções por RVA podem associar-se a manifestações clínicas graves e é crucial a vigilância da variabilidade genotípica desse vírus para monitorizar a emergência de novas cepas e o impacto da imunização nesses pacientes.
OBJECTIVE: To describe the genotypic variability of group A rotavirus (RVA) found in immunosuppressed and non-immunosuppressed pediatric patients treated at the Hospital de Clínicas da Universidade Federal do Paraná (HC-UFPR), Curitiba, Paraná. METHODS: A cross-sectional study was conducted with 1,140 stool samples collected from April, 2001 to December, 2008 in outpatients and hospitalized patients with acute gastroenteritis referred to the hospital. RVA diagnosis was performed through the latex agglutination method and enzyme immunoassay. Reverse transcription followed by multiplex hemi-nested polymerase chain reaction (PCR) and nucleotide sequencing were used for genotype characterization. Genotype combinations, clinical data, epidemiological data, laboratory data, and presence of hospital-acquired infections were reported. RESULTS: A total of 80 rotavirus-positive stool samples were analyzed. The most frequent associations between genotypes G and P were: G4 P[8] (38.9%), G1 P[8] (30.5%), G9 P[8] (13.9%), G2 P[4] (6.9%), and G3 P[8] (1.4%). G2 P[4] was the most prevalent genotype after the vaccine implementation in the years 2006 and 2008. A total of 62.5% of children aged less than 12 months were found to be infected. Of these, 55.6% had severe dehydration and 26.7% needed intensive care. A frequency of 12.5% of nosocomial infections was found. No correlation was observed between genotype and severity of infection in the study patients. CONCLUSION: RVA infections can be associated with severe clinical manifestations, and the surveillance of genotypic variability of this virus is crucial to monitor the emergence of new strains and the impact of the immunization in these patients.
