  • Recém-nascidos no serviço de urgência pediátrica: casuística de um ano
    Publication . Garcia, C; Mascarenhas, I; Teixeira, AT; Bento, V; Alves, C; Almeida, H
    Introdução: Os serviços de urgência pediátrica são ambientes particularmente deletérios para os recém-nascidos. A identifica - ção precoce da doença neste grupo é fundamental, uma vez que o atraso diagnóstico pode estar associado a consequências graves. A maioria dos sistemas de triagem utilizados nos serviços de urgência pediátrica não possui algoritmos específicos para os recém-nascidos. Este estudo teve como objetivos caracterizar os recém-nascidos que recorreram ao serviço de urgência pediátrica, analisar a sua categorização pelo Sistema de Triagem de Manchester e identificar fatores de risco associados ao internamento. Métodos: Estudo retrospetivo efetuado pela análise dos dados de recém-nascidos admitidos no serviço de urgência pediátrica no ano de 2012. Resultados: Foram incluídos 779 recém-nascidos com idade média de 16,78 dias. Os principais diagnósticos de admissão foram as infeções respiratórias (21,9%) e a cólica do lactente (21%). Ficaram internados 22,2%, sendo os principais motivos as infe - ções respiratórias baixas (19,7%), os episódios de apparent life threatening event (15%) e as gastroenterites agudas (10,8%). A presença de hipoxemia e a realização de exames complementares no serviço de urgência pediátrica associaram-se a maior taxa de internamento (p = 0,001), assim como a atribuição de nível de prioridade “urgente”, “muito urgente” ou “emergente” pelo Sistema de Triagem de Manchester (p = 0,001). Discussão: O recurso dos recém-nascidos ao serviço de urgência pediátrica neste hospital ocorre maioritariamente por situa- ções de doença aguda. Os diagnósticos de admissão mais frequentes apresentam pouca gravidade clínica, já que contribuem pouco para o número de internamentos. Verifica-se uma correlação entre o nível de prioridade atribuído pelo Sistema de Triagem de Manchester e a necessidade de internamento neste grupo etário.

  • RSV infection – Risk factors, complications and treatment in two Portuguese hospitals
    Publication . Bento, V; Machado, R; Ferreira, M; Conde, M; Carreiro, H; Ferreira, G; Brito, MJ
    Abstract. The aim of this study was to characterize the infection by respiratory syncytial virus (RSV), identify risk factors, complications and compare treatment strategies in children admitted to two Portuguese hospitals. It was a retrospective study performed between January 2005 and December 2006. Demographic and socioeconomic data, risk factors, treatment, compli- cations and medical follow-up were analyzed. A total of 328 children were studied (135 from Hospital Dona Estefˆania and 193 from Hospital Fernando Fonseca), about half (52.7%) being male, with a mean age of 5 months. 41% of the patients were from a poor socioeconomic context, 55.8% had older siblings, 32.2% had smoking parents and 11.3% had reactive airway disease. Complications occurred in 76.1% of the patients, namely, hypoxemia (63.5%), secondary bacterial infection (26.5%), atelectasis (11.5%), respiratory failure (10%) and apnea (2.4%). Most of the patients (92.3%) were treated with bronchodilators, 69% had oxygen supplementation, 45% were on antibiotics and 31% were treated with systemic corticosteroids. Ten percent needed mechanical ventilation. Twenty-seven (8.2%) children developed reactive airway disease. Having older siblings (63.1% vs. 49.3% P = 0.05) and being newborn (32.7% vs. 16.5% P = 0.006) resulted as risk factors for complications, while the risk factors identified for bacterial infection were having older siblings (71.4% vs. 55.7%; P = 0.013) and being from a poor socioeconomic context (64.7% vs. 47.6%; P = 0.017). The treatment strategies differed in the two hospitals (Hospital Fernando Fonseca vs. Hospital Dona Estefˆania) regarding the use of systemic corticosteroids (1.6% vs. 73.3%, P = 0.000) and antibiotics (39.4% vs. 52.6%; P = 0.011). RSV infections can result in serious complications. According to the current knowledge, most of the therapeutic measures carried out in this study were probably unnecessary. It is important to establish clear national guidelines for the treatment of RSV infection.

  • TINU syndrome: two clinical cases of tubulo-interstitial nephritis and uveitis
    Publication . Bento, V; Castro, I; Batista, J; Mesquita, J
    TINU (Tubulo-Interstitial Nephritis and Uveitis) syndrome is a rare disease of unknown aetiology characterised by the association between interstitial nephritis and uveitis. The authors present the cases of two young children whose symptoms began with anorexia and weight loss, associated with renal failure and proteinuria of tubular origin. One child also presented anaemia, glycosuria without hyperglycaemia and microhaematuria. A few months later both developed uveitis. In both cases the renal biopsy showed changes compatible with interstitial nephritis. As interstitial nephritis and uveitis aetiologies were not identified, TINU syndrome was suggested as a possible diagnosis. In both children there was a complete resolution, with one needing systemic steroids and immunosuppressive treatment. TINU syndrome should always be considered in the differential diagnosis of patients with renal and ophthalmologic changes.

  • Urinary tract infections under 24 months old: Is it possible to predict the risk of renal scarring?
    Publication . Miranda, AM; Garcia, C; Bento, V; Pinto, S
    Background: Urinary tract infection is one of the most common bacterial infections in the first two years of life and it can lead to irreversible renal scarring. Renal scintigraphy is the gold standard method for detection of renal scars. The aim of our work was to revise the cases of pyelonephritis, detect the possible predictors for renal scarring and compare those results we would have obtained if we had followed current NICE guidelines. Methods: Retrospective analysis of all patients aged under 24 months evaluated in the paediatric department and diag- nosed with pyelonephritis during a three -year period. We excluded the cases in which no renal scintigraphy was performed. Results: Of the 59 children analysed, 50.8% were boys and 86.4% were under one -year old. Escherichia coli was the predominant bacteria. Renal ultrasonography showed abnormal findings in 23 patients (39%). The incidence of renal scarring was 15.3%. Age, atypical urinary tract infection and abnormal renal ultrasonography seem to be correlated with risk of renal scarring, although the results were not statistically significant. C -reactive protein level is significantly correlated with renal scarring risk (p=0.047). Working outside the NICE guidelines allowed us to catch 7 further renal scars. Conclusions: It’s arguable if renal scintigraphy must be performed in all cases of pyelonephritis diagnosed in the first 24 months of life or only when there are other risk factors for renal scarring. Age, atypical urinary tract infection, C -reactive protein level and renal ultrasonography results must be taken into account in the decision to perform renal scintigraphy in a child. More prospective studies with larger cohorts are needed.
