Child abuse: a painful reality behind closed doors

Child abuse violates the most basic rights of children and adolescents. As documented in the main article of this issue of Challenges, child abuse is a massive, daily and underreported problem that affects the population of Latin America and the Caribbean. It manifests itself in different forms, including physical and psychological aggression, rape and sexual abuse, and takes place in the home, in neighbourhoods, at school, at work and in legal and child protection institutions. Abuse tends to be transmitted from one generation to the next, and the individuals most often responsible are parents or other adult members of the household

Molecular evidence of mother-to-child transmission of HTLV-IIc in the Kararao Village (Kayapo) in the Amazon Region of Brazil

Amostras de sangue de índios nativos na aldeia Kararao (Kayapó) foram analisadas, usando-se métodos sorológico e molecular, para caracterizar a infecção e analisar a transmissão do HTLV-II. Observou-se reatividade específica em 3/26 indivíduos, dos quais duas amostras eram de uma mãe e de seu filho. A análise pela RFLP de regiões pX e env confirmou a infecção pelo HTLV-II. A seqüência de nucleotídios do segmento 5'LTR e a análise filogenética mostraram alta similaridade (98%) entre as três amostras e o protótipo HTLV-IIa (mot) e confirmaram a ocorrência do subtipo HTLV-IIc. Houve uma alta similaridade genética (99,9%) entre as amostras da mãe e do filho e a única diferença foi uma deleção de dois nucleotídios (TC) na seqüência materna. Estudos epidemiológicos anteriores entre índios nativos do Brasil forneceram prova da transmissão intrafamilial e vertical do HTLV-IIc. O presente estudo fornece evidência molecular da transmissão do HTLV-IIc de mãe para filho, um mecanismo que em grande parte é responsável pela endemicidade do HTLV nessas populações epidemiologicamente fechadas. Embora a verdadeira via de transmissão seja desconhecida, a amamentação materna poderia ser a mais provável.

Estrutura e dinâmica de famílias com um filho com necessidades educacionais especiais

No contexto brasileiro, a investigação acerca das necessidades educacionais especiais concentra-se no estudo das dificuldades e possibilidades de inclusão desses alunos em classes regulares de ensino, enfatizando os processos de ensino e aprendizagem. Poucos estudos, no Brasil, admitem a família como objeto de análise, embora não se questione a sua importância para o desenvolvimento infantil. Dessa forma, com base no modelo bioecológico e na teoria estrutural sistêmica, admitindo-se a família como um campo de desenvolvimento comum a todos os membros faz-se necessário conhecer o modo como ela se estrutura para atender as demandas decorrentes da necessidade especial de seu filho e os efeitos dessa dinâmica nos demais membros. A partir disso objetivou-se descrever, a estrutura e a dinâmica de famílias de crianças com necessidades educacionais especiais, além de: analisar as interações e relações estabelecidas dentro de cada subsistema (conjugal, fraternal, parental) e entre eles, assim como identificar a organização familiar, a partir dos mecanismos de coesão e hierarquia de acordo com o modelo estrutural sistêmico. Como estratégia de pesquisa utilizou-se o estudo de casos múltiplos, com duas famílias de crianças com necessidades educacionais especiais, sendo uma menina surda, de dez anos, e um menino, de doze anos, com dificuldades de aprendizagem. Os instrumentos e técnicas aplicados foram: Roteiro de Entrevista Semi-Estruturado, Inventário de Rotina (IR), Observação Sistemática, Diário de Campo, Family System Test (FAST) e Genograma. Os escores de proximidade obtidos no FAST foram coerentes com os resultados do IR, demonstrando maior coesão na díade mãe-filho que na díade pai-filho, nas duas famílias; quanto à flexibilidade das fronteiras, em geral, a percepção das famílias foi de fronteiras rígidas, nos sistemas, familiar, parental e fraternal, sendo que, a distribuição de hierarquia foi percebida pela díade parental, nas duas famílias, como sinal de prediletância, para o subsistema fraternal, e dominação, para o parental, o que interferiu nas estruturas relacionais desses subsistemas percebidas pelos membros. Na avaliação do subsistema fraternal, a ausência de poder, representada pelos pais e a representação dessa variável pelas crianças resultou em diferenças de percepção, no grupo. Portanto, esse estudo permitiu, por meio da identificação das relações e percepções dos membros das famílias, a compreensão de sua dinâmica e a influência desta, na trajetória desenvolvimental das crianças e do grupo, a partir, das demandas decorrentes do diagnóstico e das estratégias peculiares a cada família para enfrentar as necessidades especiais de suas crianças. Percebe-se que a família, sendo a principal parceira da escola na educação, precisa ser olhada como um sistema cujas estratégias relacionais são fundamentais para que a criança tenha suas habilidades estimuladas podendo, assim, superar suas dificuldades.

Evaluation of nutritional indicators and body composition in patients with advanced liver disease enrolled for liver transplantation

PURPOSE: Malnutrition is prevalent in patients with advanced liver disease (LD) related to multifactorial causes. Fluid retention can underestimate the nutritional status based on anthropometric measures. We evaluated nutritional indicators and body composition (BC) in patients with liver cirrhosis and correlated them with LD severity. METHODS: Forty three patients with LD enrolled for liver transplantation were evaluated by Anthropometric measures, subjective evaluation (Global Assessment of Nutritional Status - SGA) and biochemical indicators. Single-frequency electrical bioimpedance (SFE-BIA) was used to evaluate body composition (BC). It measured resistance (R), reactance (Xc) and the phase angle (PA). LD severity was estimated by Child-Pugh and Meld criteria (Model for End-Stage Liver Disease). RESULTS: Child-Pugh index between patients was 7.11±1.70 and Meld was 12.23±4.22. Arm Circumference, Arm Muscle Circumference and Arm Muscle Area, SGA, hemoglobin, hematocrit and albumin showed better correlation with disease severity. Xc and PA showed correlation both with Meld and Child-Pugh score when BC were evaluated. PA was depleted in 55.8% of the patients. CONCLUSIONS: Diagnosis of malnutrition varied according to the method. Global assessment of nutritional status showed better correlation with disease severity than with objective methods. Single-frequency electrical bioimpedance for body composition analysis in cirrhotic patients must be cautiously used; however, primary vectors seems to be valid and promising in clinical practice.

Social aspects of dental caries in the context of mother-child pairs

The relationship between mother and child in the context of oral health has traditionally been exposed by the scientific literature in microbiology, which lacks a broad and necessary discussion of health and illness seen as processes, both biological and social. Objective: Investigate the family social determinants associated with the caries history of children and the need for dental treatment (NDT) among their mothers was the objective of this study. Material and Methods: This research employed a cross-sectional study of mother-child pairs living in southern Brazil. Data collection occurred in public institutions of early childhood education. The instruments included a structured questionnaire administered to mothers and clinical oral examinations of the mothers and children. The social variables considered were marital status, maternal education, number of children, income, employment status, and frequency of visits to a dental professional. The measured outcomes were the maternal NDT and child caries history. Data were analyzed by the chi-square test (chi 2) and by discriminant analysis. Results: The final sample consisted of 272 mother-child pairs and it was found that the greatest need for treatment was among mothers with low educational level and low family income who rarely or never visited a dentist. Tooth decay was less frequent in only child, and most frequent in children of mothers with low educational attainment, and in children in lower income households who rarely or never visited the dentist. The social determinants of caries in children and of the maternal NDT were similar. It follows that the maternal NDT and caries history among children were strongly associated with maternal education (p<0.0001), household income (p<0.0001), and frequency of visits to a dental professional (0.0018). Caries history among children was also associated with number of children in the household (p<0.0001). Conclusions: The results suggest that the caries experience in children depended less on the family social variables than on the maternal NDT.

Medicinal plants in pregnancy and lactation: perception of the health risk and practical educational group in Araraquara, São Paulo State, Brazil

The use of medicinal plants among pregnant women and lactating is a common practice in diverse countries. However, many medicinal plants are contraindicated during pregnancy and lactating, due to various adverse effects, such as teratogenic, embryotoxic and abortive effects, exposing these women, their fetus and babies to health unknown risks. Thus, the purpose of this commentary, was to analyze the perception about the use of medicinal plants by pregnant women and lactating registered in the "baby on board" NGO, Araraquara, São Paulo state, Brazil, between 2010 at 2013. The group was constituted by 48 women, between the first and last trimester of pregnancy or whilst breastfeeding. Information was collected during group meetings by oral interview, using a questionnaire, as script. The nature of the study was a qualitative analysis. The results were based on reports about the use of medicinal plants by pregnant women during group meetings: use, indication of use, knowledge about risks. All participants received written and oral information about the study and they gave a written informed consent. The use of medicinal plants is a reality among pregnant and lactating women of the "baby on board" NGO. They reported that they feel that "natural" products are not harmful for their health. The primary information sources for the majority of women about medicinal plants during pregnancy are family, neighbors and herbalists. The plants most cited (in popular name in Brazil) were: senna, chamomile, boldo, lemon balm, lemon grass. They were used mainly for: nausea, heartburn, indigestion, flatulence, intestinal and abdominal pain, anxiety, intestinal constipation and low milk production. The pregnant and lactating women lacked knowledge about the health risks of the use of medicinal plants and herbal medicines in pregnancy and lactation. They also reported difficulties in clarifying some questions about the use of medicinal plants with their doctors. The results of the present study showed that educative actions about the rational use of medicinal plants in pregnancy and breastfeeding could be part of the operating protocols to promote the maternal and child health programs in Araraquara. Thus, our results also suggest the importance of creating institutionalized places, to the implementation of continued education programs about rational use of medicinal plants in pregnancy and lactation. These targeted programs are not only for health professionals, but also for community members, pregnant women and breastfeeding. Our results pointed out the importance of guidance of doctors and healthcare professionals on the scientific studies about medicinal plants and herbal medicines and the risk/benefit of using herbs during pregnancy. Finally, it is noted the importance of the health professionals to inform women of childbearing on risks to their health, as well as on possibilities of utilization of herbs during fertile period, giving special attention to the potential risk of self-medication.

Defining and Measuring Poverty in Nebraska

Data recently released by the Census Bureau estimate that 47.4 million Americans, or about one-insix, are living in poverty. This latest estimate has drawn criticism from some observers who see it as an attempt to artificially inflate the magnitude of poverty in America. The criticism results from a change in methodology that included not just income (the Whitehouse Office of Management and Budget (OMB) poverty threshold for 2009 is $22,050 a year for a family of four), but also made adjustments, taking into account such things as region, out-of-pocket medical expenses and child care costs, that in total add about seven-million individuals to the poverty population.

Mutations in SRCAP, Encoding SNF2-Related CREBBP Activator Protein, Cause Floating-Harbor Syndrome

Floating-Harbor syndrome (FHS) is a rare condition characterized by short stature, delayed osseous maturation, expressive-language deficits, and a distinctive facial appearance. Occurrence is generally sporadic, although parent-to-child transmission has been reported on occasion. Employing whole-exome sequencing, we identified heterozygous truncating mutations in SRCAP in five unrelated individuals with sporadic MS. Sanger sequencing identified mutations in SRCAP in eight more affected persons. Mutations were de novo in all six instances in which parental DNA was available. SRCAP is an SNF2-related chromatin-remodeling factor that serves as a coactivator for CREB-binding protein (CREBBP, better known as CBP, the major cause of Rubinstein-Taybi syndrome [RTS]). Five SRCAP mutations, two of which are recurrent, were identified; all are tightly clustered within a small (111 codon) region of the final exon. These mutations are predicted to abolish three C-terminal AT-hook DNA-binding motifs while leaving the CBP-binding and ATPase domains intact. Our findings show that SRCAP mutations are the major cause of FHS and offer an explanation for the clinical overlap between FHS and RTS.
