COVID-19: Distance learning to empower educators and health assistants in rural areas.

BACKGROUND: Educators and health assistants can act as key players in controlling the pandemic. In general, they are respected by the community, especially in rural areas, and can help guide and raise the population's awareness of preventive measures. The objective of this paper is to evaluate the results in knowledge progress of an e-learning course offered to educators and health assistants by a public university and to analyze the profile and satisfaction of the participants. MATERIALS AND METHODS: A single group pre- and post-test design based on a questionnaire, interventional, study was conducted in the period from April 20th to June 20th. All participants of the course answered sociodemographic and satisfaction questionnaire and a pre- and post-test. Data were descriptively arranged and regarding the distribution and comparison of means and frequency, paired t-test for group comparisons. P < 0.05 was statistically significant. Data were collected from the Moodle® teaching platform, without identifying the participants. RESULTS: A total of 674 participants were enrolled in the five groups, and 583 concluded the course (86.5%). The reasons for those who did not access the entire course (n = 47) were: Lack of time, difficulty in accessing the internet, and lack of experience with distance learning courses. On the evaluation of the course platform, from the tutors in general and the degree of satisfaction in several questions, participants marked maximum grades. The comparison between pre- and post-proficiency scores showed increased proficiency of the enrolled groups (P < 0.0001). CONCLUSIONS: The course contributed to the training of health assistants and educators, preparing them to act in a participatory way in the prevention and control of the pandemic. The course was well evaluated and there was a progression of knowledge by the participants.

Covid-19: e-Learning as a tool for improving the knowledge / Covid-19: e-learning como ferramenta para melhoria do conhecimento

Abstract: Introduction: Preventing and fighting COVID-19 are of the utmost importance. In this context, the importance of using telemedicine tools has grown, including teleconsultations, epidemiological telemonitoring, remote diagnosis, support, and training of health professionals. Objective: This article aims to report the results of a distance-training course on SARS-CoV-2 and COVID-19. We analyze the course adherence, the students' profile, pre, and post-test proficiency index and satisfaction with the course. Methods: This is a cross-sectional study that evaluated data from the course on SARS-CoV-2 and COVID-19. The data were analyzed in terms of distribution and comparisons of means and frequencies. A paired t-test was used to compare the pre and post-test grades. A p-value <0.05 was considered significant. Data were collected from the Moodle teaching platform, without identifying the participants. Results: From March 23 to May 14, the course was offered to 1,008 medical students and health care providers. Most were from the state of Minas Gerais, some from other Brazilian states, and Mozambique. The majority completed the course, with an 89.8% adherence. The evaluations related to the course, the tutors, the degree of satisfaction, and the security for the professional performance after the course obtained maximum scores. The comparison between the pre and post grades showed proficiency gain (p<0.0001). Conclusion: The course has contributed to the training of medical students and health professionals from Brazil and Mozambique. The organizing committee was able to prepare students and provide knowledge to professionals with difficulty to access good technical and evidence-based information. After the training, the students were selected to work on university projects aiming at supporting city halls, health departments, and the community.

The Role of Genetic and Immune Factors for the Pathogenesis of Primary Sclerosing Cholangitis in Childhood.

Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease characterized by chronic inflammation of the biliary tree resulting in liver fibrosis. PSC is more common in male less than 40 years of age. The diagnosis of PSC is based on clinical, laboratory, image, and histological findings. A biochemical profile of mild to severe chronic cholestasis can be observed. Endoscopic retrograde cholangiography is the golden standard method for diagnosis, but magnetic resonance cholangiography is currently also considered a first-line method of investigation. Differences in clinical and laboratory findings were observed in young patients, including higher incidence of overlap syndromes, mostly with autoimmune hepatitis, higher serum levels of aminotransferases and gamma-glutamyl transferase, and lower incidence of serious complications as cholangiocarcinoma. In spite of the detection of several HLA variants as associated factors in large multicenter cohorts of adult patients, the exact role and pathways of these susceptibility genes remain to be determined in pediatric population. In addition, the literature supports a role for an altered immune response to pathogens in the pathogenesis of PSC. This phenomenon contributes to abnormal immune system activation and perpetuation of the inflammatory process. In this article, we review the role of immune and genetic factors in the pathogenesis of PSC in pediatric patients.

Nutritional evaluation of children with chronic cholestatic disease / Avaliação nutricional de crianças com colestase crônica

Abstract Objective: To evaluate the nutritional status of children with persistent cholestasis and to compare the anthropometric indices between children with and without liver cirrhosis and children with and without jaundice. Methods: Children with persistent cholestasis, i.e. increased direct bilirrubin or changes in the canalicular enzyme gamma-glutamyl transferase (GGT), were included. The anthropometric measures were weight (W), height or length (H), arm circumference (AC), triceps skinfold thickness (TST), arm muscle circumference (AMC), and body mass index (BMI). Results: Ninety-one children with cholestasis, with current median age of 12 months, were evaluated. W/age (A) and H/A indices below −2 Z-scores were observed in 33% and 30.8% of patients, respectively. Concerning the W/H index and BMI, only 12% and 16% of patients, respectively, were below −2 Z-scores. Regarding AC, 43.8% of 89 evaluated patients had some depletion. Observing the TST, 64% of patients had depletion, and 71.1% of the 45 evaluated patients had some degree of depletion regarding the ACM index. Conclusion: Evaluation using weight in patients with chronic liver diseases may overestimate the nutritional status due to visceromegaly, subclinical edema, or ascites. Indices that correlate weight and height, such as W/H and BMI, may also not show depletion because of the chronic condition in which there are depletion of both weight and height. TST, AC, and ACM are parameters that better estimate nutritional status and should be part of the management of patients with liver diseases and cholestasis.

Resumo Objetivo: Avaliar a situação nutricional de crianças com colestase persistente e comparar os índices antropométricos entre crianças com e sem cirrose hepática e crianças com e sem icterícia. Métodos: Foram incluídas crianças com colestase persistente, ou seja, aumento da bilirrubina direta ou alterações na enzima canalicular, gamaglutamiltransferase (GGT). As medidas antropométricas foram peso, estatura ou altura, circunferência do braço (CB), espessura da prega cutânea do tríceps (TST), circunferência muscular do braço (CMB) e índice de massa corporal (IMC). Resultados: Foram avaliadas 91 crianças com colestase, com idade média de 12 meses; 33% e 30,8% dos pacientes apresentaram índices P/I e A/I com escore Z abaixo de –2, respectivamente. Com relação ao índice P/A e IMC, somente 12% e 16% dos pacientes, respectivamente, apresentaram escore Z abaixo de –2. Com relação à CB, 43,8% de 89 pacientes avaliados apresentaram alguma depleção. Observando a TST, 64% dos pacientes que apresentaram depleção, 71,1% dos 45 pacientes avaliados apresentaram algum grau de depleção com relação ao índice de CMB. Conclusão: A avaliação do peso em pacientes com doenças hepáticas crônicas poderá superestimar a situação nutricional devido a visceromegalia, edema subclínico ou ascite. Os índices que correlacionam peso e altura, como P/A e IMC, também podem não mostrar depleção devido à doença crônica em que há depleção tanto do peso quanto da altura. A TST, BC e CMB são parâmetros que estimam melhor a situação nutricional e devem fazer parte de gestão de pacientes com doenças hepáticas e colestase.

Diagnostic criteria for autoimmune hepatitis in children: a challenge for pediatric hepatologists.

Autoimmune hepatitis (AIH) is a progressive inflammatory liver disorder that is rare in children and adolescents. AIH has a broad clinical spectrum and a quick response to treatment with corticosteroids and immunosuppressive medication. The available diagnosis criteria have limitations and should be evaluated in pediatric populations. Recently, some studies reported that the 2008 simplified diagnostic criteria for AIH could be used in children with high sensibility and specificity. In addition, the authors reported that globulin and immunoglobulin G levels can be used interchangeably for diagnostic purposes. They also demonstrated that the 2008 simplified criteria fail in identifying patients with fulminant hepatic failure. Here, we discuss the limitations of the use of these criteria in pediatric patients and the requirement of more studies to improve the diagnosis of AIH in children.

Evaluation of the presence of hereditary and acquired thrombophilias in Brazilian children and adolescents with diagnoses of portal vein thrombosis.

OBJECTIVE: The aim of this study was to describe the prevalence of main hereditary thrombophilias, Janus kinase 2 (JAK2) V617F mutation, antiphospholipid antibody syndrome (APS), and hyperhomocysteinemia in Brazilian children and adolescents diagnosed with portal vein thrombosis (PVT) without associated hepatic disease. METHODS: A cross-sectional study was carried out with 32 children with PVT in accompaniment at Hospital das Clínicas of the Universidade Federal de Minas Gerais from January 1990 to July 2011. Laboratory evaluation of thrombophilias was performed from September 2010 to July 2011. RESULTS: Thirty-two patients were evaluated; 59% were boys. Median age at diagnosis was 2.4 years. Mean time of patients' accompaniment was between 4.7 and 5.2 years. The presence of hereditary and acquired thrombophilias occurred in 34.4% of patients, and 9 of them also showed other risk factors in the previous history evaluation. Risk factors were absent in the previous history of 18 patients (56.3%). Two patients showed persistent high titres of anticardiolipin antibodies. Hyperhomocysteinemia was not observed. One patient was heterozygous for factor V Leiden and prothrombin G20210A mutation (3.1%). Eleven patients (34.4%) showed heterozygous methylenetetrahydrofolate reductase (MTHFR) C677T, and no patient had the JAK2V617F mutation. CONCLUSIONS: Even after investigation of main hereditary and acquired thrombophilia, PVT remains without apparent cause in most patients. Nevertheless, association of local and systemic risk factors seems to be important also in the pediatric age group. Therefore, despite the low prevalence, a complete investigation, which includes both hereditary and acquired thrombophilias, may be necessary.

Portal vein thrombosis in children and adolescents: 20 years experience of a pediatric hepatology reference center.

CONTEXT: Portal vein thrombosis refers to a total or partial obstruction of the blood flow in this vein due to a thrombus formation. It is an important cause of portal hypertension in the pediatric age group with high morbidity rates due to its main complication - the upper gastrointestinal bleeding. OBJECTIVE: To describe a group of patients with portal vein thrombosis without associated hepatic disease of the Pediatric Hepatology Clinic of the Hospital das Clínicas, Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brazil with emphasis on diagnosis, presentation form and clinical complications, and the treatment of portal hypertension. METHODS: This is a descriptive study of a series of children and adolescents cases assisted from January 1990 to December 2010. The portal vein thrombosis diagnosis was established by ultrasound. RESULTS: Of the 55 studied patients, 30 (54.5%) were male. In 29 patients (52.7%), none of the risk factors for portal vein thrombosis was observed. The predominant form of presentation was the upper gastrointestinal bleeding (52.7%). In 20 patients (36.4%), the initial manifestation was splenomegaly. During the whole following period of the study, 39 patients (70.9%) showed at least one episode of upper gastrointestinal bleeding. The mean age of patients in the first episode was 4.6 ± 3.4 years old. The endoscopic procedure carried out in the urgency or electively for search of esophageal varices showed its presence in 84.9% of the evaluated patients. The prophylactic endoscopic treatment was performed with endoscopic band ligation of varices in 31.3% of patients. Only one died due to refractory bleeding. CONCLUSIONS: The portal vein thrombosis is one of the most important causes of upper gastrointestinal bleeding in children. In all non febrile children with splenomegaly and/or hematemesis and without hepatomegaly and with normal hepatic function tests, it should be suspect of portal vein thrombosis. Thus, an appropriate diagnostic and treatment approach is desirable in an attempt to reduce morbidity and mortality.

CONTEXTO: Trombose da veia porta refere-se a uma obstrução total ou parcial do fluxo de sangue nesta veia devido à formação de um trombo. É uma causa importante da hipertensão porta na faixa etária pediátrica, com taxas elevadas de morbidade devido a sua principal complicação - a hemorragia digestiva alta. OBJETIVO: Descrever o grupo de crianças e adolescentes com trombose de veia porta sem doença hepática associada do Ambulatório de Hepatologia Pediátrica do Hospital das Clínicas da UFMG, Belo Horizonte, MG, Brasil, com ênfase no diagnóstico, forma de apresentação, complicações clínicas e na abordagem da hipertensão porta. MÉTODOS: Trata-se de estudo descritivo de uma série de casos de crianças e adolescentes atendidos de janeiro de 1990 a dezembro de 2010. O diagnóstico de trombose de veia porta foi estabelecido por ultrassonografia. RESULTADOS: Dos 55 pacientes analisados, 30 (54,5%) eram do gênero masculino. Em 29 pacientes (52,7%) não foi identificado nenhum fator de risco para trombose de veia porta. A forma de apresentação predominante foi hemorragia digestiva alta (52,7%). Em 20 pacientes (36,4%), a manifestação inicial foi esplenomegalia. Durante todo o período de seguimento, 39 pacientes (70,9%) apresentaram, pelo menos, um episódio de hemorragia digestiva alta. A média de idade dos pacientes neste primeiro episódio foi de 4,6 ± 3,4 anos. O exame endoscópico, seja realizado na urgência ou eletivamente para pesquisa de varizes esofágicas, mostrou sua presença em 84,9% dos pacientes avaliados. O tratamento endoscópico profilático foi realizado com ligadura elástica de varizes em 31,3% dos pacientes. Apenas um evoluiu para óbito devido a sangramento refratário. CONCLUSÕES: A trombose de veia porta é uma das causas mais importantes de hemorragia digestiva alta em crianças. Deve-se suspeitar de trombose de veia porta em toda criança com esplenomegalia afebril e/ou hematêmese, sem hepatomegalia e com testes de função hepática normais. Desta forma, uma abordagem diagnóstica e terapêutica adequada é desejável na tentativa de reduzir a morbimortalidade.

Novas recomendações para o atendimento ao paciente pediátrico gravemente enfermo / New recommendations for critically ill pediatric patient care

A American Heart Association publicou em outubro de 2010 uma nova versão das diretrizes para a reanimação cardiorrespiratória e emergência cardiovascular, visando garantir a alta qualidade da reanimação e otimização das condições clínicas do paciente com o retorno da circulação. Para o atendimento de urgências ou emergências na faixa etária pediátrica, o profissional de saúde deve receber treinamento específico e buscar atualizações frequentes, Este artigo tem por objetivo apresentar e discutir as novas diretrizes para a faixa etária pediátrica. Foram realizadas revisão e análise crítica dos pontos mais importantes referentes ao suporte básico e avançado de vida em pediatria, As manobras de reanimação cardiorrespiratória devem ser instituídas rapidamente, de forma efetiva e com alta qualidade, ou seja, com compressões torácicas fortes e rápidas (mínimo de 100 compressões por minuto), permitindo retorno do tórax à posição inicial e com mínimas interrupções. A sequência de atendimento à parada mudou para "CAS", iniciando as manobras pela compressão torácica, a seguir abrindo vias aéreas e fornecendo ventilações. No suporte avançado algumas recomendações foram publicadas relativas ao monitoramento do paciente e das ações, oferta de oxigênio e doses de medicações. A assistência ao paciente pediátrico gravemente enfermo deve ser planejada pelos diversos serviços, sendo recomendada a elaboração de protocolos institucionais baseados nas melhores evidências. Os profissionais envolvidos devem receber treinamento com a utilização da simulação, práticas de vivência emocional e trabalho em equipe...

American Heart Association published last October new guidelines for cardiopulmonary resuscitation and emergency cardiovascular care, aimed at ensuring the high quality of resuscitation and optimization of clinical conditions regarding the patients return circulation. For urgent or emergency care in pediatric patients, health professionals should receive specific training and get frequent updates. This articte aims to present and discuss the new guidelines for pediatric patients. It also reviews and offers the critica I analysis of the most important sup- port for the basic and advanced life support in pediatrics. The cardiopulmonary resuscitation should be instituted quickly, effectively and with high quality, i.e., hard and fast chest compres- sions (at least 100 compressions per minute), allowing the chest return to the starting position, and with minimal interruptions. The sequence for cardiopulmonary resuscitation changed to "CAB" maneuvers starting by chest compression, then opening the airway and providing ventilation. In advanced support some recommendations were published on monitoring and actions for ill pediatric patient, oxygen supply and doses of medications. The assistance to critically ill pediatric patient should be planned by several services and the development of local protocols based on literature data should be recommended. The professionals involved should be trained using of simulation, practicing emotiona! experience and teamwork...

Trombose de veia porta em crianças e adolescentes: revisão de literatura / Portal vein thrombosis in children and adolescents: literature review

Trombose de veia porta (TVPO) refere-se à obstrução total ou parcial do fluxo sanguíneo nessa localização, secundária à formação de trombos, Essa entidade se mostra importante na faixa etária pediátrica, por ser causa importante de hipertensão porta, com elevadas taxas de morbidade devido à sua principal complicação - a hemorragia digestiva alta (HDA). Aproximadamente 79% das crianças com diagnóstico de trombo- se de veia porta apresentarão ao menos um episódio de HDA. A etiologia da trombose é variada e, na maioria dos casos, há associação de fatores locais e sistêmicos, sendo o cateterismo umbilical o principal fator etiológico encontrado em crianças. A importância dos distúrbios de coagulação entre esses fatores está se tornando mais acentuada à medida que novos estudos e métodos diagnósticos são disponibilizados. O tratamento varia de acordo com a forma de apresentação - aguda ou crônica - e com a existência ou não de complicações associadas à TVPO, No quadro agudo a anticoagulação está indicada na maioria dos casos, enquanto no quadro crônico sua indicação acontece geralmente quando há trombofilias associadas, Na evolução crônica, o tratamento se direciona às complicações decorrentes da hipertensão porta secundária à TVPO.

Approximately 79% of lhe children diagnosed with PVT will show at least one episode of upper gastrointestinal bleeding during their lives. The etiology of portal vein lhrombosis is varied and, in most cases, there is an associalion of local and systemic tactors, and lhe umbilical calheterization is lhe main etiological tactor found in children. The importance of coagulation disorders among these factors is becoming greater as new studies and diagnostic methods are available. Treatment varies according to the form of presentation - acute or chronic - and the presence or absence of complications associated with PVT. In acute thrombosis, anticoagulation is indicated in most cases, while in the chronic condition is usually indicated when the patient has thrombophilia.In chronic disease, treatment is directed at complications of portal hypertension secondary to PVT.

Gastroenterite eosinofílica em criança, levando à desnutrição / Eosinophilic gastroenteritis and children with malnutrition

A gastroenterite eosinofílica é uma afecção caracterizada pela infiltração maciça de eosinófilos no trato gastrointestinal. Foi descrita pela primeira vez por Kaijser em 1937 e pode acometer qualquer área do trato gastrointestinal. A causa e o mecanismo de infiltração de eosinófilos são ainda desconhecidos. A apresentação pode variar, dependendo da localização, assim como da profundidade e da extensão do acometimento, e geralmente tem curso crônico. É uma doença relativamente rara, que afeta predominantemente adultos jovens do sexo masculino. (AU)

Eosinophilic gastroenteritis is a condition with extensive infiltration of eosinophils in the gastrointestinal tract. It was first described by Kaijser en 1937 and can affect any part of gastrointestinal tract. The cause and the real way for infiltration are unknown. Presentation may vary depending on location as well as depth and extent of bowel wall involvement and usually runs a chronic relapsing course. It is a rare disease that affects mainly young adult men. (AU)

Padronização na descrição das imagens radiológicas no tórax / Standardization of thoracic radiological images description

Objetivo: apresentar a terminologia básica utilizada na descrição de imagens radiológicas do tórax mais comuns na pediatria. Métodos: foram selecionados 16 referências bibliográficas em pesquisa realizada nas bases de dados medline e no Lilacs, em português, espanhol e inglês, utilizando-se as palavras-chave radiologia, tórax e terminologia. Conclusões: não existe padronização e normalização na descrição de radiografias do tórax. Embora existam termos específicos publicados na literatura, a sua utilização é, ainda, incipiente. A variedade de definições e nomenclatura utilizadas pelas diferentes universidades e residências médicas dificulta a interpretação das informações geradas, a formulação de pesquisas e a realização de estudos comparativos. Sistematização da análise da radiologia torácica deve ser realizada por todos profissionais.
