RESUMEN

OBJECTIVE: Hemophagocytic lymphohistiocytosis syndrome (HLHS) is characterized by an immunological hyperactivation of cytotoxic T cells, natural killer cells, and macrophages, leading to the secretion of proinflammatory cytokines. HLHS associated with Visceral Leishmaniasis might be difficult to diagnose once symptoms are similar, resulting in the death of untreated patients. Our aim is to describe a series of cases of Visceral Leishmaniasis with HLHS admitted to a referral hospital for infectious diseases. CASE DESCRIPTION: All 115 cases of Visceral Leishmaniasis referred to a referral center for pediatric infectious diseases were reviewed to identify the cases of HLHS. Five cases (4.5%) were confirmed with HLHS and they presented fever, splenomegaly, cytopenia, hypertriglyceridemia or hypofibrinogenemia, increased ferritin and hemophagocytosis in the bone marrow. COMMENTS: It important to rule out HLHS in children with infectious diseases that do not respond adequately to treatment or in patients with severe symptoms, especially in leishmaniasis endemic areas.

RESUMEN

The aim of this study was to evaluate the concordance between two versions of the scoring system (2011 and 2019), recommended by the Brazilian Ministry of Health, for the diagnosis of pulmonary tuberculosis (PTB) in children and adolescents. A retrospective descriptive study was performed to assess the medical records of children and adolescents with PTB, in TB units from Brazilian cities located in Rio de Janeiro, Minas Gerais, and Parana States, from January 1 st , 2004, to December 1 st , 2018. Patients aged 0 to 18 years old with a diagnosis of PTB were included. The comparison between the two scoring systems showed a moderate concordance according to the κ coefficient value = 0.625. Fourteen patients showed a reduction in the TB score, going from 30 points in the 2011, to 25 points or less in the 2019 one. Seventy one percent of these 14 patients had radiological changes suggestive of PTB and 86% had tuberculin skin tests greater than 10 mm. The study concluded that a moderate agreement was observed between the 2011 and 2019 scoring systems, with an increase in the number of patients scoring 25 points or less in 2019, which can eventually hinder the diagnosis of PTB.

RESUMEN

As infecções congênitas por herpes-vírus apresentam alta prevalência ou são responsáveis por alta morbimortalidade de recém-nascidos. Nesta revisão estão abordados o herpes-vírus simplex, o vírus Varicela zoster e o citomegalovírus como agentes de infecções em gestantes, feto e recém-nascidos, incluindo medidas para profilaxia da transmissão vertical e recomendações para propedêutica e terapêutica do binômio mãe e filho.


Congenital infections by the herpes virus show high prevalence or are responsible for high morbidity and mortality in newborns. In this review, the herpes virus simplex, Varicella zoster virus, and Cytomegalovirus are addressed as infectious agents in pregnant women, fetus, and newborns, and include measures for the prevention of mother-to-child transmissionand recommendations for the propaedeutics and therapy of both mother and child.

RESUMEN

A toxoplasmose, parasitose prevalente em todo o mundo, quando adquirida durante a gestação pode ser transmitida ao feto e causar, dentre outros problemas, atraso no desenvolvimento neuropsicomotor, estrabismo, déficit visual e perdas auditivas. A prevenção da transmissão vertical deve ser iniciada antes da con- cepção ou o mais precocemente possível durante o pré-natal. A identificação de gestantes susceptíveis (soronegativas) deve ser acompanhada de orientações escritas e verbais sobre as formas de aquisição da infecção (profilaxia primária) e, se bem realizada, tem se mostrado eficaz. As mulheres com contato prévio com o parasito, antes da gestação, se imunocompetentes, apresentam muito baixo risco de infectar o concepto. Mas, as gestantes agudamente infectadas devem ser identificadas precocemente para instituição de terapêutica adequada (profilaxia secundária) com o objetivo de evitar a infecção ou diminuir as suas conseqüências para o feto. Considerando-se que a infecção adquirida, assim como a congênita, são geralmente assintomáticas, devemos utilizar a triagem sorológica da mãe e, posteriormente da criança suspeita, para diagnosticar e tratar esses casos. Os autores se pro- põem a apresentar uma orientação prática para abordagem do binômio mãe/filho suspeitos de toxoplasmose, com base nos conhecimentos disponíveis no momento e de acordo com o protocolo utilizado no Serviço de Doenças Infecciosas e Parasitárias, setor de Infectologia Pediátrica, do Hospital das Clínicas da Universidade Federal de Minas Gerais.


The toxoplasmosis, a prevalent parasitosis throughout the world, when acquired during pregnancy can be transmítted to the fetus and cause, among other problems, delay in the neuropsychomotor development, strabismus and visual and hearing impairment. The vertical transmission prevention must be initiated before conception or as early as possible in the prenatal assessment. The identification of susceptible pregnant woman (nega tive blood test) must be accompanied by written and verbal orientation about how the disease can be acquired (primary prophylaxis) and, if well per- formed, has showed good efficacy. Women with previous contact with the parasite, before pregnancy, if imunecompetents, show a very low risk of infecting the child. But, the pregnant women acutely infected must be identified early for the implementation of adequa te therapeutics (secondary prophylaxis) aiming to avoid infection ar at least decrease its consequence to the fetus. Considering that the acquired infection as well as the congenital are usually assymptomatic, we should use the mother's serological screening and, afterwards the child's to diagnose and treat these cases. The authors intend to show a public guideline in the assessment of the mother/child suspects of being infected with toxoplasmosis, based in the current available knowledge and according to the protocol used in the Serviço de Doenças Infecciosas e Parasitárias, Setor de Infectologia Pediátrica, Hospital das Clínicas da Universidade Federal de Minas Gerais.
