- Hypereosinophilia and Severe Bone Disease in an African Child: An Unexpected DiagnosisPublication . Bota, S; Alves, P; Constantino, C; Maia, RHypereosinophilic syndromes are rare in children. Sporadic, mild-severity FIP1L1-platelet-derived growth factor receptor α (PDGFRα) rearrangement cases have been reported, mainly in boys. We present the case of a 5-year-old girl referred from her African country of birth, due to severe constitutional symptoms, multifocal bone pain, headache, gastrointestinal complaints, cardiomyopathy and unexplained hypereosinophilia. She presented multiple end-organ diseases and striking bone involvement. Although she had a positive serology for Strongyloides stercoralis, extensive evaluation detected a FIP1L1-PDGFRA fusion gene. Systemic corticosteroids and low-dose imatinib were started and the child became asymptomatic. After 9 months of treatment, FIP1L1-PDGFRA was no longer detected.
- Impacto das Infeções Respiratórias Viricas Múltiplas na Evolução de Crianças Gravemente DoentesPublication . Verdelho Andrade, J; Bota, S; Marques, F; Casimiro, A; Estrada, J; Santos, MIntrodução: As infecções respiratórias baixas são a principal causa de mortalidade em crianças até aos 5 anos. A utilização do painel rápido multiplex por PCR melhora a identificação do diagnóstico etiológico. Objetivos: Comparar a evolução de infecções respiratórias víricas com um ou mais agente isolado em crianças admitidas por insuficiência respiratória aguda (IRA) em cuidados intensivos. Métodos: Estudo retrospetivo (39 meses, dezembro 2014 a fevereiro 2018) de doentes com IRA e identificação de pelo menos um vírus por PCR multiplex. Estudou-se a idade, género, PCR multiplex e evolução. Consideraram-se dois grupos: A um vírus e B mais do que um vírus. Utilizaram-se os testes Qui-quadrado ou Exato de Fisher para testar associações entre variáveis. Resultados: Obtiveram-se 54 IRA com agente identificado: grupo A=42 e B=12. Mediana de idade de 4 e 5 meses (A/B), género masculino 57% e 50% (A/B). No mesmo período, verificaram-se 1149 internamentos, com PRISM médio de 2,68 e mortalidade de 2,78%. No grupo A, o PRISM médio foi de 7,50 e no B de 5,17. Não se registaram óbitos. A doença crónica e a falência de órgão foram mais frequentes no grupo A (33% e 8%, p=0,088; 83% e 67%, p=0,206). Os vírus mais frequentes foram: A - Vírus Sincicial Respiratório (43%), B - Rhinovírus (58%), com coinfecção bacteriana em 21% e 8% (A/B, p=0,303). O grupo B necessitou mais de ventilação (A - 67%, B - 75%, p=0,512), sem diferença no modo (não invasiva p=0,571, invasiva p=0,571). Houve necessidade de acesso central em 24% e 25% (A/B, p=0,932) e vasopressores em 10% e 0% (A/B, p=0,564). A demora média foi 11 e 10 dias (A/B). Conclusão: O estudo sugere que a coexistência de vários vírus no mesmo doente não alterou significativamente a evolução e o prognóstico.
- Nephrolithiasis in a Portuguese Pediatric PopulationPublication . Andrade, J; Bota, S; Francisco, T; Santos, R; Neto, G; Abranches, MIntroduction and Aims: Nephrolithiasis incidence in children has increased considerably. It is associated with substantial morbidity, recurrence and increased adulthood cardiovascular risk and chronic kidney disease. A thorough investigation is essential, as rare forms of urolithiasis have increased risk of renal failure. We aim to determine the epidemiology and outcomes of a pediatric population with nephrolithiasis presented in a nephrology unit of a tertiary centre. Methods: Retrospective study of the records of all children (<18 years) with nephrolithiasis diagnosis between 2008‑17. Clinical features, etiology, recurrence, treatment, and outcomes were evaluated and compared throughout the study period through two equal periods (2008‑12 versus 2013‑17). Results: We identified 80 cases: isolated nephrolithiasis (86%) and associated with nephrocalcinosis (14%). Mean follow‑up was 36 months (14–120). Median age at presentation was 8.6 years [3 months – 17 years]: 21% < 2 years‑old and 46% ≥ 10 years. The annual ratio of referrals for nephrolithiasis increased on average 1.2% per year [0.3‑11.8%]. Multiple etiological factors were present in 34%. A metabolic abnormality was identified in 54%: hypocitraturia (34%), hypercalcuria (24%), hyperoxaluria (15%), hyperuricosuria (15%) and cystinuria (1%), without age predominance (p=0.2). Urinary tract infection (24%) was the next most significant etiology and was more frequent below 2 years of age (p=0.001) and associated with struvite calculi (p=0.033). Median age at diagnosis was significantly lower in the study’s first half (5 vs 10 years; p=0.019) and an infectious etiology was more frequent (p=0.043). In a logistic‑regression analysis, a family history of nephrolithiasis was associated with a metabolic cause (p<0.01). Sixty‑three percent became stone free and 24% had recurrence. Discussion: Nephrolithiasis new referrals gradually increased throughout the study period. The most common etiology was metabolic, which is usually responsible for nephrolithiasis appearance and its recurrence, emphasizing the need for a complete evaluation.
