Clinical forms and diagnosis of tuberculosis in children and adolescents during the COVID-19 pandemic.

OBJECTIVE: The present study aimed to describe the clinical forms and the time taken to diagnose new tuberculosis cases and to statistically analyze the isolated and combined forms of the disease in children and adolescents treated at a university hospital in Rio de Janeiro during the first year of the COVID-19 pandemic in Brazil. METHODS: This was a cross-sectional study that used retrospective data on children (0-9 years old) and adolescents (10-18 years old) with pulmonary (PTB), extrapulmonary (EPTB), and combined tuberculosis (PTB + EPTB) followed up at the outpatient clinic from January 2019 to March 2021. Categorical data were analyzed by descriptive statistics and expressed as frequency and proportions. Categorical variables were compared using the Chi-square test, and numerical variables using Student's T-test. RESULTS: A total of 51 cases were included, 63% (32/51) of which comprised patients in the year of the pandemic (group A), while 37% (19/51) were patients attended in previous years (group B). In group A, 19% (6/32) of the patients presented PTB, 59% (16/32) had EPTB, and 31% (10/32) had PTB+EPTB. In group B, 42% (8/19) of the patients presented PTB, 42% (8/19) had EPTB, and 16% (3/19) had PTB+EPTB. CONCLUSION: Our study revealed more tuberculosis cases in the first year of the pandemic than in the same period of the previous year, with greater variation of sites affected by the disease, including rarer and more severe forms.

Diretrizes da Associação Brasileira de Alergia e Imunologia e Sociedade Brasileira de Pediatria para sibilância e asma no pré-escolar / Guidelines of the Brazilian Association of Allergy and Immunology and the Brazilian Society of Pediatrics for wheezing and asthma in preschool children

A asma é uma das doenças crônicas de maior frequência na infância. Parcela significativa de crianças com asma desenvolve sintomas nos primeiros anos de vida, mas nem sempre a sua confirmação diagnóstica é fácil. Outras causas de sibilância que podem gerar confusão diagnóstica, além da complexidade para a obtenção de medidas objetivas, tais como a realização de provas de função pulmonar nessa faixa etária, são justificativas para esse fato. Especialistas na abordagem desses pacientes, da Associação Brasileira de Alergia e Imunologia e da Sociedade Brasileira de Pediatria, após revisão extensa da literatura pertinente elaboraram esse documento, onde são comentados os possíveis agentes etiológicos, prevalência, diagnóstico diferencial, assim como tratamento e prevenção da sibilância e asma em pré-escolares.

Asthma is one of the most frequent chronic diseases in childhood. A significant portion of children with asthma develop symptoms in the first years of life, but diagnostic confirmation is not always easy. The difficulty is justified by other causes of wheezing that can generate diagnostic confusion, and by the complexity involved in obtaining objective measures ­ such as pulmonary function tests ­ in this age group. Specialists with expertise in the approach of these patients, from both the Brazilian Association of Allergy and Immunology and the Brazilian Society of Pediatrics, after extensive review of the pertinent literature, developed this document to discuss possible etiological agents, prevalence, differential diagnosis, as well as treatment and prevention of wheezing and asthma in preschool children.

Lethality by pneumonia and factors associated to death / Letalidade por pneumonia e fatores associados ao óbito

OBJECTIVE: To describe the case-fatality rate (CFR) and risk factors of death in children with community-acquired acute pneumonia (CAP) in a pediatric university hospital. METHOD: A longitudinal study was developed with prospective data collected from 1996 to 2011. Patients aged 1 month to 12 years were included in the study. Those who left the hospital against medical orders and those transferred to ICU or other units were excluded. Demographic andclinical-etiological characteristics and the initial treatment were studied. Variables associated to death were determined by bivariate and multivariate analysis using logistic regression. RESULTS: A total of 871 patients were selected, of whom 11 were excluded; thus 860 children were included in the study. There were 26 deaths, with a CFR of 3%; in 58.7% of these, penicillin G was the initial treatment. Pneumococcus was the most common pathogen (50.4%). From 1996 to 2000, there were 24 deaths (93%), with a CFR of 5.8% (24/413). From 2001 to 2011, the age group of hospitalized patients was older (p = 0.03), and the number of deaths (p = 0.02) and the percentage of disease severity were lower (p = 0.06). Only disease severity remained associated to death in the multivariate analysis (OR = 3.2; 95%CI: 1.2-8.9; p = 0.02). CONCLUSION: When the 1996-2000 and 2001-2011 periods were compared, a significant reduction in CFR was observed in the latter, as well as a change in the clinical profile of the pediatric in patients at the institute. These findings may be related to the improvement in the socio-economical status of the population. Penicillin use did not influence CFR. .

OBJETIVO: Descrever a taxa de letalidade (TL) e os fatores de risco de óbito em crianças com pneumonia grave adquirida na comunidade (CAP) em um hospital universitário pediátrico. MÉTODO: Foi desenvolvido um estudo longitudinal com dados prospectivos coletados de 1996 a2011. Foram incluídos no estudo pacientes com idade entre 1 mês e 12 anos de idade. Foram excluídos aqueles que deixaram o hospital desconsiderando as recomendações médicas e aqueles transferidos para UTI ou outras unidades. Foram estudadas as características demográficas, clínicas e etiológicas e o tratamento inicial. As variáveis associadas a óbito foram determinadas por análise bivariada e multivariada utilizando regressão logística. RESULTADOS: Foi selecionado um total de 871 pacientes, dos quais 11 foram excluídos; assim, foram incluídas no estudo 860 crianças. Houve 26 óbitos, com uma TL de 3%; em 58,7% desses, penicilina G foi o tratamento inicial. Pneumococo foi o patógeno mais comum (50,4%). De 1996 a 2000, houve 24 óbitos (93%), com uma TL de 5,8% (24/413). De 2001 a 2011, a faixa etária de pacientes internados foi mais velha (p = 0,03) e o número de óbitos (p = 0,02) e o percentual de gravidade das doenças foram menores (p = 0,06). Apenas a gravidade das doenças continuou associada a óbito na análise multivariada (RC = 3,2; IC de 95%: 1,2-8,9; p = 0,02). CONCLUSÃO: Quando os períodos de 1996-2000 e 2001-2011 foram comparados, foi observada uma redução significativa na TL no último período, bem como uma alteração no perfil clínico dos pacientes hospitalizados no instituto. Esses achados podem estar relacionados à melhora na situação socioeconômica da população. O uso de penicilina não influenciou a TL. .

Preoperative pulmonary assessment of children for liver transplantation.

Pulmonary assessment should be part of the preoperative investigation of pediatric patients with chronic liver disease undergoing liver transplantation, as it allows the identification of pulmonary alterations that influence candidacy for transplantation and survival. To describe pulmonary changes found in pediatric patients who were candidates for liver transplantation. Retrospective study of 17 pediatric liver transplant candidates undergoing preoperative pulmonary evaluation assessing pulmonary clinical data, arterial blood gas analysis, CXR, respiratory function test by spirometry, pulmonary scintigraphy, and CEE. Ten patients presented normal chest roentgenograms. The most common radiographic change was interstitial infiltrate in the lung bases. Of the five patients with PaO(2) <70 mmHg, four had cyanosis and dyspnea and two were diagnosed with HPS with intrapulmonary shunt evidenced by contrast echocardiogram. Two patients presented with intrapulmonary shunt but without hypoxemia. Spirometry was normal in six patients, restrictive disturbance was evidenced in one patient, obstructive in three, and combined in two. The most common scintigraphic change was heterogeneous pulmonary perfusion. Pulmonary assessment should be performed routinely in pediatric patients prior to liver transplantation, even in asymptomatic patients. Pulmonary assessment may indicate changes such as HPS that can increase postoperative morbidity/mortality.

Hemossiderose pulmonar idiopática tratada com azatioprina: relato de caso em criança / Idiopathic pulmonary hemosiderosis treated with azathioprine in a child

A hemossiderose pulmonar idiopática (HPI), principal causa de hemossiderose pulmonar em crianças, cursa com sangramento alveolar intermitente e presença de hemossiderófagos no escarro ou no lavado gástrico. O tratamento é baseado nos corticoesteróides e citostáticos, em condições especiais. Descreve-se o caso de uma menina de sete anos com HPI, que conseguiu controle parcial da doença mediante altas doses de corticoesteróide. O tratamento, no entanto, necessitou ser suspenso gradualmente visto a paciente ter desenvolvido fácies cushingóide. Foi iniciada a associação da azatioprina ao corticóide até a substituição total por azatioprina isolada, cujo uso foi mantido por quatro anos, com ótimo resultado.

Idiopathic pulmonary hemosiderosis (IPH), the main cause of pulmonary hemosiderosis in children, is characterized by intermittent alveolar bleeding and hemosiderin-laden macrophages in sputum and in gastric lavage. The treatment is based on corticosteroids and cytotoxic drugs, under special conditions. We describe the case of a 7-year-old girl with IPH who achieved partial clinical remission with high doses of corticosteroids. However, the treatment had to be discontinued because the patient developed Cushing's syndrome. Treatment was started with an azathioprine-corticosteroid combination and then changed to azathioprine alone, which was maintained for four years, with excellent results.

Pneumonia de repetição / Recurrent pneumonia

A pneumonia recorrente definida, como 3 ou mais episódios de pneumonia em 1 ano, deve melhor ser discutida entre os pediatras. O achado radiológico de normalidade entre os episódios agudos deve ser bem caracterizado. O autor discute quais os pacientes que realmente necessitam de avaliação clínica e investigação diagnóstica complementar pelo especialista.

The recurrent pneumonia episodes (three or more times a year), must be better dicussed among pediatricians. We emphasize the importance of finding normal chest roentgenograms between acute episodes; so thatit will be adequately charaterized. Therefore the identification of the patiens that really need subsequent clinical evalution and complementary diagnosis investigation by the specialist will be better select.

Pneumonias de repetição em ambulatório de pneumologia pediátrica: conceito e prevalência / Recurrent penumonia in a pediaatric pulmonology outpatient unit: concept and prevalence

Objetivo: Determinar a prevalência de pneumonias de repetição na demanda de consultas de primeira vez encaminhadas ao ambulatório de Penumologia Pediátrica do Instituto de Puericultura e Pediaatria Martagão Gesteira da UFRJ para esclarecimentos diagnóstico e revisar o conceito de pneumonias de repetição na literatura pediátrica. Método: Os dados foram obtidos através da avaliação de consultas desse tipo no período de 01/01/95 a 30/04/97. Resultados: De um total de 638 consultas, 101 foram encaminhadas com o diagnóstico presuntivo de pneumonias de repetição. Em apenas 39,6 por cento, o motivo do encaminhamento coincidiu com o conceito de pneumonias de repetição adotado pelo Serviço. Conclusão; Os autores concluíram que o conceito de pneumonias de repetição deve ser melhor esclarecido e difundido entre os médicos pediatras, pois cabe a eles a decisão de encaminhar ao especialista os pacientes com essa queixa. Cabe ressaltar a valorização do exame radiológico normal entre os episódis agudos para a caracterização do quadro de pnemonias de repetição, visando melhor determinação dos pacientes que posteriormente necessitarão de encaminhamento ao especialista para prosseguimento da investigação diagnóstica
