Vitamin A deficiency and association between serum retinol and IGF-1 concentrations in Brazilian children with Down syndrome.

OBJECTIVE: To determine the prevalence of vitamin A deficiency (VAD) and serum concentrations of retinol, correlating them with IGF-1 concentrations in preschoolers with DS. METHODS: Cross-sectional study was conducted on 47 children with DS aged 24 to 72 months, in Ribeirão Preto, Brazil. VAD was determined by the relative dose-response (RDR) test. Retinol serum concentration ≤ 0.70 µmol/L and IGF-1 serum concentration below the 3rd percentile for sex and age were considered to represent deficiency. C-reactive protein (CRP) was determined at the beginning of the study. Weight, height, and information about fever and/or diarrhea were obtained at the beginning of the study. RESULTS: VAD prevalence was 25.5% (12/47), and 74.5% (35/47) of the children had deficient retinol before the intervention. CRP was not associated with VAD. Mean IGF-1 were 103.5 ng/mL (SD = 913) for the group with VAD and 116.3 ng/mL (SD = 54.9) for the group with no VAD (p-value = 0.85); 8.5% (4/47) of the children showed deficient IGF-1, but without VAD. No association was observed between VAD and IGF-1 deficiency. A moderate positive correlation was observed between pre-intervention retinol and IGF-1 (ρ = 0.37; p-value = 0.01). CONCLUSION: a high prevalence of VAD and deficient retinol was observed and there was a positive correlation between serum retinol and IGF-1.

Pediatric multisystem inflammatory syndrome associated with COVID-19: urgent attention required.

OBJECTIVE: To identify epidemiological and clinical characteristics of multisystemic inflammatory syndrome associated with coronavirus infection as one of the severe forms of COVID-19 involvement in children and adolescents. METHODS: review was based on articles published in 2020 in the PubMed, Medline, Scopus, SciELO and Cochrane databases. SUMMARY: Multisystemic inflammatory syndrome is a serious clinical disorder that affects children and adolescents and is associated with the detection of previous exposure to SARS-CoV-2. It is characterized by the installation of a shock picture, with a significant increase in inflammatory markers such as presentations of Kawasaki Disease or shock syndrome related to Kawasaki Disease, or even toxic shock syndrome, with the clinical picture being characterized by fever of difficult control, rash, conjunctivitis, peripheral edema, generalized pain in the extremities and gastrointestinal symptoms. CONCLUSIONS: Although the vast majority of children with COVID-19 have mild symptoms, it is necessary to consider that some have a hyperinflammatory response. It is essential that health professionals receive information that can assist in the recognition of this clinical condition, differentiating it from other diagnoses, so that early and appropriate treatment is instituted.

Effects of Alcohol on the Developing Brain: The Adolescent at Risk

Adolescence is a phase of great physical, emotional and social transformations that put individuals in vulnerability and with risks of aggravations that can be definitive. Among the various characteristics of the adolescent, the experimentation of new sensations and challenges is one of the most outstanding, being responsible for several common problems in this phase of life. Among the several factors that can adversely affect adolescents, alcohol is one of themost prevalent, offering serious immediate and late risks. This article presents some characteristics of alcohol consumption among adolescents and the effects on the development of the central nervous system, highlighting the main damages that can be caused in the brain in formation (reduced white matter volume and cortices, neuronal apoptosis, demyelination). In view of the relevance of the effects of alcohol on the developing brain all efforts should be directed towards avoiding or minimizing the risks to which adolescents are subject. It also presents some measures that can be with the aim of preventing the consumption of alcohol among adolescents.

Breastfeeding and the benefits of lactation for women's health / Aleitamento materno e seus benefícios para a saúde da mulher

Abstract The offer of the maternal breast to the baby is an unquestionable right of mothers and their children, and all efforts should bemade to promote, follow and maintain exclusive breastfeeding for up to 6months and supplement it until the child completes 2 years of age. Many publications are available in the literature about the qualities of breast milk, its benefits and health repercussions, stimulating the practice of breastfeeding and supporting campaigns for its implementation. However, although it is widely known that breastfeeding is an important step in the reproductive process of women and its practice offers benefits to both mother and child, most of the available information highlights the benefits of breast milk for children, while mention of the effects of breastfeeding on the health of the mother is usually neglected. Thus, the objective of the present study is to highlight the multiple benefits of breastfeeding for the physical and emotional health of the nursing mother. The authors consulted articles published in the databases PubMed, Virtual Health Library andWeb of Science using the keywords breastfeeding, breast milk, lactation and maternal health.

Resumo A oferta do seio materno às crianças éumdireito inquestionável dasmães e de seus filhos, e todos os esforços devem ser feitos no sentido de promover, acompanhar e manter o aleitamento materno exclusivo até os 6 meses e complementado até que a criança complete 2 anos de idade. A literatura apresenta incontáveis publicações acerca das qualidades do leite materno, seus benefícios e repercussões para a saúde, estimulando a prática do aleitamento materno e embasando campanhas. Porém, mesmo sendo de conhecimento geral que a amamentação é uma importante etapa no processo reprodutivo da mulher e que sua prática oferece benefícios para mãe e filho, a grande maioria das informaçõesdestacamosbenefíciosque o leitematernooferece às crianças, esquecendo-se de mencionar todas as repercussões que o aleitamento materno traz para a saúde da mãe. Assim, o objetivo deste artigo édestacar os inúmeros benefícios que o aleitamentomaterno proporciona à saúde física e emocional da lactante. Para tanto, os autores consultaram artigos publicados nas bases de dados PubMed, Biblioteca Virtual de Saúde e Web of Science utilizando as palavras-chave aleitamentomaterno, leitematerno, lactação e saúdematerna.

Epidemiological and clinical characteristics of injuries among adolescents attended at an emergency service in the city of Ribeirão Preto, São Paulo.

CONTEXT AND OBJECTIVE: Injuries are an important cause of morbidity during adolescence, but can be avoided through learning about some of their characteristics. This study aimed to identify the most frequent injuries among adolescents attended at an emergency service. DESIGN AND SETTING: Retrospective descriptive study on adolescents attended at the emergency service of the Teaching Health Center, Faculdade de Medicina de Ribeirão Preto (FMRP), between January 1, 2009, and September 30, 2009. METHODS: Age, sex, type of injury, site, day and time of occurrence, part of body involved, care received, whether the adolescent was accompanied at the time of injury and whether any type of counseling regarding injury prevention had been given were analyzed. RESULTS: Among 180 adolescents attended, 106 (58.8%) were boys and 74 (41.1%) were girls. Their ages were: 10 to 12 (66/36.6%), 12 to 14 (60/33.3%) and 14 to 16 years (54/30%). The injuries had occurred in public places (47.7%) and at home (21.1%). The main types were bruises (45.1%) and falls (39.2%), involving upper limbs (46.1%), lower limbs (31%) and head/neck (13.1%). The injuries occurred in the afternoon (44.4%) and morning (30%), on Mondays (17.7%) and Thursdays (16.6%). Radiological examinations were performed on 53.8%. At the time of injury, 76.1% of the adolescents were accompanied. Some type of counseling about injury prevention had been received by 39.4%. CONCLUSIONS: Although the injuries were of low severity, preventive attitudes need to be incorporated in order to reduce the risks and provide greater safety for adolescents.

Acute urinary retention in a pre-school girl with constipation / Retenção urinária aguda em pré-escolar feminina com constipação intestinal

Objective: To report a case of a preschool girl who developed acute urinary retention associated with constipation. Case description: A girl aged six years old presented a 24 h history of inability to urinate. She was went twice to the emergency room during this period. In the first admission, 12 h after the onset of the symptoms, she presented abdominal pain and acute urinary retention. After the drainage by urinary catheterization of 300 mL of clear urine, she presented relief of the symptoms and, as urinalysis had no change, the patient was discharged home. Twelve hours after the first visit, she returned to the emergency room complaining about the same symptoms. At physical examination, there was only a palpable and distended bladder up to the umbilicus with no other abnormalities. Again, a urinary catheterization was performed, which drained 450 mL of clear urine, with immediate relief of the symptoms. Urinalysis and urine culture had no abnormalities. During the anamnesis, the diagnosis of constipation was considered and a plain abdominal radiography was performed, which identified large amount of feces throughout the colon (fecal retention). An enema with a 12% glycerin solution was prescribed for three days. During follow-up, the child used laxatives and dietary modifications, this contributed to the resolution of the constipation. There were no other episodes of urinary retention after 6 months of follow-up. Comments: Acute urinary retention in children is a rare phenomenon and constipation should be considered as a cause.

Objetivo: Relatar um caso de criança que desenvolveu retenção urinária aguda associada à constipação intestinal. Descrição do caso: Menina, seis anos, havia 24 horas apresentara incapacidade de liberação de esfíncter vesical. Foi atendida por duas vezes em um serviço de emergência nesse período. Na primeira consulta, 12 horas após o início do quadro, apresentava dor abdominal e retenção urinária aguda e foi feita sondagem de alívio com saída de 300mL de urina clara. Houve alívio imediato dos sintomas e, como o exame de urina tipo 1 não apresentou alterações, a paciente recebeu alta. No segundo atendimento, 12 horas após a primeira consulta, apresentava as mesmas queixas. Ao exame físico, observou-se apenas bexiga palpável e distendida até a cicatriz umbilical, sem outras alterações. Nova sondagem vesical foi feita com saída de 450mL de urina clara, com alívio imediato dos sintomas. Nenhuma anormalidade foi observada no exame de urina tipo 1 e na urocultura. Durante a anamnese, foi levantada a hipótese diagnóstica de constipação intestinal. Foi feita radiografia simples de abdome, que identificou grande quantidade de fezes em todo o cólon (retenção fecal). Enema com solução glicerinada a 12% foi prescrito por três dias. Durante o seguimento a criança fez uso de laxativos e modificações na dieta que contribuíram para a resolução da constipação intestinal. Não houve repetição do quadro de retenção urinária aguda após seis meses de acompanhamento. Comentários: A retenção urinária aguda em crianças é um fenômeno raro e a constipação intestinal deve ser considerada como uma das causas.

Percepção corporal e atividade física em uma coorte de adultos jovens brasileiros / Body image and physical activity among a brazilian youth cohort

OBJETIVO: analisar as relações entre percepção corporal, peso referido, peso aferido e atividade física entre adultos jovens da cidade de Ribeirão Preto (SP). MÉTODO: estudo de uma coorte de indivíduos nascidos entre 1978-1979, classificados segundo sexo, nível de escolaridade, índice de massa corporal e grau de atividade física, avaliado pelo International Physical Activity Questionnaire (IPAQ). RESULTADOS: foram avaliados 2035 indivíduos (51,8 por cento do sexo feminino) dos quais 1727 (84,8 por cento) referiram ter estudado mais de nove anos. Tanto a média de peso (77,6 ± 15 kg) quanto de índice de massa corporal (25 ± 4,4 kg/m²) foram superiores para o sexo masculino. Quanto à classificação da percepção corporal, 81,6 por cento das mulheres superestimaram o peso corporal e 78,2 por cento dos homens o subestimaram. Entre todos os indivíduos que subestimaram o peso corporal, 92,3 por cento tinham grau de escolaridade superior a nove anos. Os indivíduos que superestimaram o peso foram os que menos desenvolveram atividade física (58,6 por cento). Nos grupos dos indivíduos que consideraram o peso adequado ou o superestimaram, 48,3 por cento e 51,2 por cento, respectivamente, foram classificados como ativos ou muito ativos. CONCLUSÃO: índice de massa corporal e atividade física contribuíram para melhor avaliação do próprio peso, enquanto que o sexo feminino e o maior grau de escolaridade relacionaram-se diretamente com a distorção da autopercepção, com tendência a superestimar o próprio peso.(AU)

OBJECTIVE: to analyze the relationship between body image, body weight and physical activity among young adults in the city of Ribeirão Preto (SP). METHOD: a cohort study of individuals born between 1978-1979, classified by sex, education level, body mass index and physical activity level assessed by the International Physical Activity Questionnaire (IPAQ). RESULTS: 2035 individuals had been evaluated, (51.8 percent female) of whom 1727 (84.8 percent) reported having studied over nine years. Both the mean weight (77.6 ± 15 kg) and body mass index (25 ± 4.4 kg/m²) were higher for males. Regarding the classification of body awareness, 81.6 percent of women overestimated their body weight and 78.2 percent of men underestimated. Among all individuals who underestimate their body weight, 92.3 percent had schooling of more than nine years. Individuals who overestimated their weight were the least developed physical activity (58.6 percent). In groups of individuals who considered the appropriate weight or overestimated, 48.3 percent and 51.2 percent, respectively, were classified as active or very active. CONCLUSION: body mass index and physical activity have contributed to better evaluation of their own weight, whereas female gender and higher educational level had a direct relationship with the distortion of perception, with a tendency to overestimate their own weight.(AU)
