Objective: To describe clinical, radiological, epidemiological, and microbiological characteristics of pediatric patients with diagnosis of tuberculosis in a period of 15 years.Methods: Retrospective study including children and adolescents younger than 18 years diagnosed with tuberculosis in the Clinical Hospital of the Universidade Estadual de Campinas in São Paulo State, Brazil. Active tuberculosis was defined by the identification of Mycobacterium tuberculosis in culture, microscopy, or histopathological examination. Children with positive clinical history and radiological tests who had been exposed to sick adults or with positive tuberculin skin test were also considered as having active tuberculosis. Statistical analysis compared the data obtained from children younger and older than 10 years of age, since they present a disease pattern more similar to adults.Results: There were 145 identified cases, 61.4% in patients under 10 years of age. The main symptoms reported were coughing (55.9%) and fever (46.9%), and the variables of fever, coughing, weight-loss, and pain were significantly influenced by age, with a higher frequency in older children. Diagnosis was confirmed by culture, microscopy, or histopathology in 67.6% of the cases. The other cases (32.4%) had the diagnosis of tuberculosis based on clinical, radiological, and epidemiological characteristics, as well as tuberculin skin test. The positivity for culture, microscopy, and tuberculin skin test was, respectively, 65.8, 35.7, and 72.3%. History of contact with a sick adult was confirmed in 37.2%, without influence of age.Conclusions: Diagnosis of tuberculosis in children is still a challenge, since all the confirmation tests have low positivity. These results demonstrate the need for new diagnostic methods and improved strategies for searching sick contacts.
Objective: To detect factors associated with greater risk of death in infants after an apparent life-threatening event (ALTE). Methods:This cross-sectional, retrospective, descriptive and analytic study evaluated infants younger than 12 months who had a sudden event of cyanosis, pallor, hypotonia or apnea and were seen in the emergency department of a tertiary university hospital. Forward stepwise logistic regression (Wald) was used to calculate and adjust odds ratios to evaluate associations.Results: Mean age of the 145 patients included in the study was 105 days (median = 65 days). Eleven (7.6%) died, and their mean age was 189 days (median = 218 days). Mean age of survivors was 98 days (median = 62 days) (p = 0.003). Activity before the event, prematurity and number of events were not associated with death. A significant association was found with pallor. Of the 11 infants, 3 had spontaneous resolution of ALTE, whereas 8 patients [27.6%; p < 0.001; OR = 14.3 (95%CI 3.51-58.3)] did not. The associations with respiratory or cardiovascular disease were also significant. In multivariate analysis, immediate spontaneous resolution [p = 0.015; OR = 6.06 (95%CI 1.02-35.94)] and diagnosis of cardiovascular disease [p = 0.047; OR = 164.27 (95%CI 7.34-3.673.78)] remained statistically significant. Conclusion:Infants who experienced an ALTE had a higher risk of subsequent death when their age was greater than 6 months and the event had a long duration, particularly when ALTE was associated with cardiovascular disease.J Pediatr (Rio J). 2010;86(6):515-519: ALTE, apparent-life threatening event, death risk, infants. ResumoObjetivo: Identificar, na admissão dos lactentes com após eventos com aparente risco de morte (apparent life-threatening event, ALTE), fatores que possam indicar maior risco de evolução para o óbito.Métodos: Estudo transversal retrospectivo, descritivo e analítico com lactentes menores de 12 meses, com evento súbito de cianose, palidez, hipotonia e/ou apneia, atendidos na unidade de emergência de hospital universitário de nível terciário. Para avaliação da associação, determinaram-se os valores de odds ratio bruto e ajustado por regressão logística (método stepwise forward Wald). Resultados:Foram avaliados 145 pacientes com idade média de 105 dias (mediana = 65 dias). Onze (7,6%) evoluíram para óbito, com idade média de 189 dias (mediana = 218 dias), enquanto que a idade média dos sobreviventes foi de 98 dias (mediana = 62 dias) (p = 0,003). Atividades que precederam o evento, antecedente de prematuridade e número de episódios não apresentaram associação com o óbito. Apresentou relação significativa o relato de palidez pelos observadores. Entre os 11 lactentes, 3 apresentaram melhora imediata e espontânea; já 8 pacientes [27,6%; p < 0,001; OR = 14,3 (IC95% 3,51-58,3)] não tiveram melhora espontânea. Os diagnósticos de doença do trato respiratório e do sistema cardiocirculatório também foram significantes. Na análise multivariada, mostraram significância estatística: não melhora imediata e espontân...
This report describes the clinical features and outcome of 61 pediatric hospitalized patients with influenza-like infection. Fever, cough and respiratory distress were the most common symptoms of the infection. Fifteen patients presented positive RT-PCR results for influenza A (H1N1). The group with positive results was compared with the negative one. The main significant difference was antibiotic usage and the need of mechanical ventilation in the patients with H1N1-virus infection. Among the 11 patients who required intensive care due to respiratory failure, 3 from the positive group died and none from the negative group.
