RESUMEN
According to the World Health Organisation, as of October 2022, there have been 55,560,329 reported cases of SARS-COV-2 in patients under 19 years old. It is estimated that about 0.06% of these patients may develop MIS-C, representing more than 2 million children worldwide. This systematic review and meta-analysis examined the pooled prevalence of cardiovascular manifestation and cardiac complications in children hospitalised with MIS-C. The PROSPERO register number is CRD42022327212. We included case-report studies, case-control studies, cohort studies, and cross-sectional studies, as well as clinical trials or studies describing cardiac manifestations of MIS-C and its sequelae in a paediatric population. Initially, 285 studies were selected, but there were 154 duplicates, and 81 were excluded because they did not fit the eligibility criteria. Thus, 50 studies were selected for review, and 30 were included in the meta-analysis. A total sample size of 1445 children was included. The combined prevalence of myocarditis or pericarditis was 34.3% (95% CI: 25.0%-44.2%). The combined prevalence for echocardiogram anomalies was 40.8% (95% CI: 30.5%-51.5%), that of Kawasaki disease presentation was 14.8% (95% CI: 7.5%-23.7%), and that of coronary dilation was 15.2% (95% CI: 11.0%-19.8%). The rate of electrocardiogram anomalies was 5.3% (95% CI: 0.8%-12.3%), and the mortality rate was 0.5% (CI 95%: 0%-1.2%). Furthermore, 186 children still had complications at discharge, with a combined prevalence of such long-lasting manifestations of 9.3% (95% CI: 5.6%-13.7%). Studies that assess whether these children will have an increased cardiovascular risk with a greater chance of acute myocardial infarction, arrhythmias, or thrombosis will be essential for healthcare planning.

We evaluated neurologic complications following noncongenital Zika virus infection in 11 children who presented with central nervous system signs. Zika virus RNA was detected by real-time reverse transcription-polymerase chain reaction in cerebrospinal fluid. Approximately one-quarter of patients required antiepileptic medication in follow-up, and 2 children progressed to learning difficulties or developmental delay.

This study aims to characterize the acute neurological manifestations caused by DENV, ZIKV, and YFV during hospitalization; identify the risk factors associated with persistent neurological complications after discharge; and evaluate the time to resolution during clinical follow-up. A prospective study evaluated 505 children, between March 2014 and July 2019, hospitalized with neurological manifestations and that doctors suspected infection of the central nervous system (CNS). Viral infection of collected cerebrospinal fluid (CSF) was confirmed by real-time reverse transcription-polymerase chain reaction (RT-PCR). Patients were clinically followed up after hospital discharge. Analysis of predictive factors and survival curves was performed. This study identified clinical symptoms and changes in the CSF laboratory, electroencephalogram (EEG), and CNS image as predictors of complications in children with confirmed infection in the CNS by DENV, ZIKV, or YFV. No statistical difference was found (p value 0.574) in the time to the resolution of complications in children after hospital discharge between the three types of flaviviruses. Children with YFV, detected in CSF samples, had a 53% higher risk of developing neurological complications. Performing etiological diagnosis by RT-PCR of CSF samples of children with neurological manifestations, especially during Flavivirus outbreaks, is an essential tool for improving the prognosis and clinical follow-up of these patients.

BACKGROUND: Covid-19 has the respiratory tract as the main target of infection, and patients present mainly dyspnea, pneumonia, dry cough, and fever. Nevertheless, organs outside the respiratory tract had been reported in recent studies, including the gastrointestinal tract and liver. The host innate immune system recognizes pathogen-associated molecular patterns (PAMPs) through their pattern recognition receptor (PRRs). Toll-like receptor 7 (TLR-7) is a pattern recognition receptor recognizing ssRNA (SARS-CoV-2 is an ssRNA). Polymorphisms are characterized by two or more alternative forms of a distinct phenotype in the same population. Polymorphisms in tlrs genes can negatively influence the immune response to infectious diseases. There are several references in the literature to non-synonymous single nucleotide (rs) polymorphisms related to several genes. Some of them are important for the innate immunity, as rs 179008 (tlr-7), rs3775291 (tlr3), rs8177374 (tir domain-containing adaptor protein, tirap), rs1024611 (monocyte chemoattractant protein-1, mcp-1) and rs61942233 (2'-5'-oligoadenylate synthase-3, oas-3). CASE PRESENTATION: We identified a 5-year-old-male child with gastrointestinal symptoms and fever presenting acholic stool and jaundice, who was positive for SARS-CoV-2 IgM, IgA, and IgG and presenting the Gln11Leu rs 179008 in tlr-7. The child presented high levels of aspartate aminotransferase, alanine aminotransferase, bilirubin, C-reactive protein, D-dimer, gamma-glutamyl transferase, alkaline phosphatase, and was negative for serological tests for hepatitis A, B, C, E, HIV 1 and 2, herpes virus, cytomegalovirus, Epstein-Barr virus, and negative for RTqPCR for Influenza A and B, RSV and SARS-CoV-2. We also investigated other SNPs in the tlr-3 (rs3775291), tirap (rs8177374), mcp-1 (rs1024611), and oas-3 (rs61942233) genes, and no mutation was detected. After an interview with the child's caregivers, any possible accidental ingestion of drugs or hepatotoxic substances was ruled out. CONCLUSION: To our knowledge, this is the first report of a SARS-CoV-2 caused hepatitis in a male child that has the tlr-7 Gln11Leu rs 179008, which could impair an efficient initial immune response. The knowledge of the patient's immune deficiency could improve the treatment to correct this deficiency with specific medications.

The Chikungunya Virus (CHIKV) already has endemic circulation in about 100 countries and the number of infected patients increases every year, due to the effectiveness of the vector and human universal susceptibility to infection. The virus can also be transmitted from mother to child, more frequently intrapartum. About 50 % of neonates with CHIKV symptoms will have neurodevelopmental delay. It is therefore an infection of worldwide concern with a great impact on people's quality of life. The objective of this work is to describe two cases of confirmed vertical transmission by chikungunya virus, one of them with intrauterine infection and death of the neonate. Neonates with vertical chikungunya infection may present with clinical sepsis in the first few days of life, which is why this is a very important diagnosis, especially during outbreaks of the infection.

BACKGROUND: The effects of SARS-CoV-2 gestational exposure on child development remain inconclusive. AIMS: To analyze the effects of SARS-CoV-2 gestational exposure on neurodevelopment until 12 months. STUDY DESIGN: Prospective cohort study conducted in five municipalities in Southeast Brazil from August 2021 to September 2022. SUBJECTS: Infants were recruited from a serological survey performed during neonatal screening and followed up to 12 months old. We included 224 infants exposed to SARS-CoV-2 during pregnancy and 225 non-exposed, according to the serology results of the newborn as well as their mothers and the maternal antenatal RT-PCR results. OUTCOME MEASURES: Developmental assessments were performed at 6 and 12 months using the Survey of Wellbeing of Young Children-Brazilian Version (SWYC-BR). Children with suspected developmental delay (SDD) at 6 and 12 months were considered at high risk for developmental delay (HRDD). Additionally, risk factors associated with SDD were examined. RESULTS: There were 111 children identified with SDD and 52 with HRDD. SARS-CoV-2 gestational exposure was not associated with SDD. Exposure in the first gestational trimester increased SDD risk by 2.15 times compared to the third. Cesarean delivery predicted SDD (OR 1.56; 95%CI 1.01-2.42) and HRDD (OR 1.91; 95%CI 1.04-3.48). Additionally, suspected maternal depression predicted SDD (OR 1.76; 95%CI 1.01-3.10). CONCLUSION: SARS-CoV-2 gestational exposure did not increase the developmental delay risk. However, our findings suggest that the earlier the gestational exposure, the greater the developmental delay risk at 12 months. Cesarean delivery and suspected maternal depression increased the developmental delay risk, independent of virus exposure.

This study evaluates the range of neurological manifestation in children with COVID-19 (neuro-COVID-19) both with and without the multisystem inflammatory syndrome (MIS-C) and the persistence of symptoms after hospital discharge. The study was conducted as a prospective study of children and adolescents under 18 years of age who were admitted to a children's hospital for infectious diseases from January 2021 to January 2022. The children had no previous neurological or psychiatric disorders. Out of the 3021 patients evaluated, 232 were confirmed to have COVID-19 and 21 of these patients (9%) showed neurological manifestations associated with the virus. Of these 21 patients, 14 developed MIS-C, and 7 had neurological manifestations unrelated to MIS-C. There was no statistical difference regarding the neurological manifestations during hospitalization and outcomes between patients with neuro-COVID-19 who had or did not have MIS-C, except for seizures that occurred more frequently in patients with neuro-COVID-19 without MIS-C (p-value = 0.0263). One patient died, and 5 patients still had neurological or psychiatric manifestations at discharge, which persisted for up to 7 months. The study highlights that SARS-CoV-2 infection can affect the central and peripheral nervous system, particularly in children and adolescents with MIS-C, and that it is crucial to be vigilant for long-term adverse outcomes, as the neurological and psychiatric effects of COVID-19 in children are emerging during an important stage of brain development.

Here we report three clinical cases of children with sickle cell disease (SCD) and severe COVID-19 who evolved with complications during hospitalization or after discharge. They present single nucleotide polymorphisms in tlr-7 and tirap genes, identified from 37 patients under 16 years old hospitalized from September 2020 to May 2021 in the Hospital João Paulo II, Belo Horizonte, Brazil. They presented significant complications of SCD as acute chest syndrome, splenic sequestration, and pain crisis during hospitalization or up to 2 months after SARS-CoV-2 infection. They all required transfusion of concentrated red blood cells and hospitalization in a reference hospital to care for children with SCD.
RESUMEN
This serological survey, conducted in five Brazilian municipalities, evaluated the use of dried blood spots (DBS), obtained from newborns and their mothers, to detect SARS-CoV-2 IgG antibodies. DBS were obtained from 4,803 neonates aged up to seven days and their mothers, both asymptomatic, at public health care clinics during newborn screening. DBS were processed by ELISA to detect IgG antibodies against SARS-CoV-2 nucleocapsid antigen. Mothers of seropositive neonates were interviewed about sociodemographic characteristics and clinical and laboratory antecedents. Non-satisfactory samples, dyads with incomplete data, and vaccinated mothers were excluded. Of the 1,917 DBS dyads samples analyzed, 14.7% of neonates showed IgG antibodies against SARS-CoV-2. Among seropositive neonates, 73.2% of their mothers were also seropositive. More than half of the mothers with seropositive neonates denied clinical or laboratory suspicion of COVID-19 during pregnancy. Suspicion occurred in the third trimester for 24.6% of the mothers. This study tested an innovative strategy to improve the understanding of COVID-19 antibody dynamics during pregnancy and suggests the feasibility of a universal serological survey in puerperal women and neonates.

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.

BACKGROUND: Viruses are a common cause of central nervous system (CNS) infections. However, studies of CNS viral pathogens in pediatric patients are poorly explored because viral infections are often erroneously diagnosed as bacterial infections. METHODS: 299 CNS samples were collected from pediatric patients aged from one month to 14 years old. A total of 140 viral meningitis cases that met the inclusion criteria were included in this study. In 38 of the 140 cerebral spinal fluid (CSF) samples (27.1%), conventional and real-time PCR were used to identify viruses commonly associated with CNS infections. RESULTS: Among them, 23 patients (16.5%) tested positive for flaviviruses such as dengue, Zika, and yellow fever virus, eight patients (5.7%) were positive for enterovirus (ENTV), and six patients (4.3%) were positive for human herpesvirus 1/2. We also identified one case of dengue virus and ENTV co-infection. CONCLUSIONS: A correlation between clinical symptoms and laboratory findings for the viruses was identified. Our study also reinforces the importance of including viruses in the laboratory diagnosis of CNS infections especially flaviviruses, which assists public health authorities in implementing early interventions.

The aim was to assess neurological complications in children with an invasive neurological disease by dengue virus (DENV) and the time to resolve symptoms after hospital discharge. A prospective study was conducted at a referral hospital for infectious diseases in Brazil between March 2014 and July 2019. All children hospitalized with neurologic manifestations and DENV RNA detected by real-time reverse transcription-polymerase chain reaction (RT-qPCR) in cerebrospinal fluid (CSF) were followed up until complete resolution of neurological complications. On average, they were followed up for 16 months. Among 56 DENV-positive children, 39% had some neurologic complications after hospital discharge and found that 19.6% were discharged with anticonvulsants due to seizures, 10.7% developed motor complications (e.g. muscle weakness, paresis, ataxia, and walking disability), 5.4% had headaches, and 14.3% had sleep disorders. Among the 56 children, only three had a clinical diagnosis of dengue because the symptoms are nonspecific and 35% showed no change in cerebrospinal fluid (CSF). The average time to resolve complications was 5.9 months (ranging from 1 m to 32 m). These results should alert physicians to the difficulties of a clinical diagnosis of an infection that causes neurological complications after discharge in a significant number of children. RT-qPCR's etiological diagnosis of DENV infection enabled better clinical follow-up for early intervention in children with neurological complications.

Background - Yellow fever (YF) is a viral hemorrhagic fever that is transmitted by arthropods. It can occur with little symptomatic manifestations to the most fulminant forms. The most effective way to avoid YF is through vaccination. There is a lack of information about the immune response of the vaccine in childhood. Methods - We described children and adolescents with YF who had been previously immunized in Minas Gerais State from July 2017 to June 2018. Results - 527 cases of YF were observed representing an incidence of 7.6/100,000 inhabitants. Only 26 patients (4.9%) were ≤ 20 years and 501 (95.1%) were > 20 years. Only 9 vaccinated patients were ≤ 20 years and 15 were > 20 years. 34.6% (9/26) of YF patients ≤ 20 years were previously vaccinated and 3% (15/501) of those > 20 years (p < 0.001). The median age at vaccination was 1 year between those ≤ 20 years and 31 years between those > 20 years (p = 0.002). Among 9 vaccinated children and adolescents ≤ 20 years, age ranged from 7 to 18 years, the most described symptoms were fever (88%), headache (77%), myalgia (77%), and abdominal pain (66%). All patients recovered from the disease and none died. Conclusion - Prior YF vaccination may be associated with mild forms of the disease in children and adolescents. YF vaccination in the first years of life may be associated with poor vaccine response and high infection rates in this group as it fail to seroconvert a significant proportion of infants.

Este inquérito sorológico, realizado em cinco municípios brasileiros, avaliou o uso de sangue seco em papel filtro (DBS), obtidas de recém-nascidos e suas mães, para detectar anticorpos IgG SARS-CoV-2. DBS foram obtidas de 4.803 neonatos com até sete dias de vida e suas mães, ambos assintomáticos, em unidades de saúde pública durante a triagem neonatal. DBS foram processadas por ELISA para detectar anticorpos IgG contra o antígeno do nucleocapsídeo SARS-CoV-2. As mães de neonatos soropositivos foram entrevistadas quanto às características sociodemográficas e antecedentes clínicos e laboratoriais. Foram excluídas amostras insatisfatórias, díades com dados incompletos e mães vacinadas. Das 1.917 amostras analisadas, 14,7% dos neonatos apresentaram anticorpos IgG contra SARS-CoV-2. Entre os recém-nascidos soropositivos, 73,2% era filho de mulheres também soropositivas. Mais da metade das mães com recém-nascidos soropositivos negaram suspeita clínica ou laboratorial de COVID-19 durante a gravidez. A suspeita de COVID-19 ocorreu no terceiro trimestre para 24,6% das mães. Este estudo testou uma estratégia inovadora para melhorar a compreensão da dinâmica de anticorpos contra SARS-CoV-2 durante a gravidez e sugere a viabilidade de realização de um inquérito sorológico universal em puérperas e neonatos.

RESUMEN
O objetivo deste artigo foi descrever as particularidades clínicas da leishmaniose tegumentar americana (LTA) e as dificuldades em realizar o diagnóstico dessa doença em Pediatria. Serão relatados três casos clínicos provenientes de serviço de referência no atendimento de doenças infecciosas para o estado de Minas Gerais, de janeiro a março de 2011, com as seguintes formas de manifestação da doença: lesão cutânea localizada e lesão cutânea disseminada. Um dos casos evidencia lesão cicatricial mutiladora. Os três casos relatados revelam a dificuldade do diagnóstico precoce de LTA. Em todos eles os pacientes foram examinados por vários pediatras e receberam tratamento empírico com antibioticoterapia, sem sucesso. Devido ao aumento da incidência da doença próximo dos grandes centros urbanos, é de suma importância que o pediatra se familiarize com os aspectos clínicos e epidemiológicos da leishmaniose para realizar um diagnóstico mais precoce, minimizando as sequelas para o paciente.
The purpose of this article is to describe the clinical characteristics of American Cutaneous Leishmaniasis ( ACL) and the difficulties in making a diagnosis of this disease in pediatrics. Three clinical cases from reference service in the care of infectious diseases in the state of Minas Gerais, January-March 2011, with the following manifestations of the disease are reported: localized cutaneous lesion and skin disseminada. An injury casesshows mutilating scar tissue. The three reported cases show the difficulty of early diagnosis of ATL. In all cases, the patients were examined for various pediatric and received empirical treatment with antibiotics without success. Due to the increased incidence of disease close to large urban centers is of paramount importance that pediatricians become familiar with the clinical and epidemiological aspects of leishmaniasis to make an earlier diagnosis minimizing the consequences for the patient.

We report one case of very severe acne-like lesions associated with amineptine (Survector). They were most prominent on the face and back, but were also observed on sites not affected by acne vulgaris, such as perineum, arms and legs. The lesions appeared after long-term self-medication of high doses. Keratoacanthoma-like lesions were also present, and the small ones were successfully treated with topical imiquimod. The case is significant since the disease is quite rare.

Não há definição única e universal do que seja saúde. A autoavaliação de saúde (AAS) é um dos indicadores mais utilizados em estudos epidemiológicos para avaliar a saúde de grupos populacionais. Sexo e idade são determinantes individuais reconhecidos da AAS. É ainda limitado o conhecimento sobre a AAS em jovens adultos (18-29anos), faixa etária pouco estudada quanto a autoavaliação de saúde. O objetivo deste estudo foi determinar e quantificar a associação entre a violência percebida na vizinhança e AAS entre jovens adultos, estratificando por sexo. A variável explicativa de interesse foi a violência urbana percebida. Participaram do estudo 955 jovens adultos (18-29anos) residentes em Belo Horizonte, Minas Gerais, de 2008 a 2009. O escore de violência urbana percebida foi construído considerando variáveis que avaliaram a insegurança do respondente e a sua percepção de medo, perigo de sofrer alguma forma de violência na vizinhança, utilizando-se análise fatorial exploratória. Com relação à autoavaliação da saúde, 81,7% dos jovens adultos considerou como muito boa/boa, 18,3% como razoável/ ruim/muito ruim. No modelo final, após ajustes para as variáveis de confusão, a violência urbana percebida na vizinhança associou-se a pior AAS apenas nas mulheres jovens (OR = 1,50; IC95%: 1,03 2,15). Embora não sejamfirmemente estabelecidos os mecanismos responsáveis por essa associação, os resultados deste estudo indicam que políticas públicas e de saúde devem considerar intervenções sobre o entorno físico e social do bairro ou vizinhança que promovam maior percepção de segurança no local em que se vive o que impactará positivamente na saúde das pessoas, especialmente das mulheres

Introdução: apresenta-se revisão histórica com as características do vírus influenza A H1N1 e a evolução da pandemia. Objetivos: observar o comportamento da população pediátrica e comparar temporalmente as ações e as recomendações dos protocolos do Ministério da Saúde vigentes em cada momento. Métodos: trata-se de estudo descritivo das ações tomadas pelo Hospital das Clínicas da Universidade Federal de Minas para atendimento hospitalar e ambulatorial pediátrico dos casos suspeitos ou confirmados de infecção pelo novo vírus. Resultados: nas publicações mundiais atuais, a infecção pelo vírus influenza A H1N1 na faixa pediátrica mostrou ter mais gravidade nos pacientes com comorbidades. A evolução das crianças que não apresentavam comorbidades foi semelhante à da influenza sazonal. Conclusões: é importante o levantamento de dados brasileiros no preparo para uma possível segunda onda de infecção por esse vírus ou outro mutante. (AU)
Introduction: This is a historical review of the influenza A vírus H1N1 subtype and the pandemic evolution. Objectives: To observe the behavior of the pediatric population and to compare over time the actions and recommendations of the protocols of the Ministério da Saúde in effect at any time. Methods: This is a descriptive study of the actions taken by the Hospital das Clinicas, Federal University of Minas Gerais for hospital and outpatient pediatric cases of suspected or confirmed infection by this new virus.
