Pharmacologic management of pain in patients with Chikungunya: a guideline

Abstract From the arrival of Chikungunya virus in the Americas in 2013 until March 2016, approximately two million cases of the disease have been reported. In Brazil, the virus was identified in 2014 and thousands of people have been affected. The disease has high attack rates, infecting 50% of a population within a few months. Approximately 50% of infected people develop chronic symptoms lasting for months or years. Joint involvement is the main clinical manifestation of Chikungunya. It is characterized by swelling and intense pain that is poorly responsive to analgesics, both in the acute and chronic phase of the disease. This significantly compromises quality of life and may have immeasurable psychosocial and economic repercussions, constituting therefore, a serious public health problem requiring a targeted approach. Physicians are often not familiar with how to approach the management of pain, frequently prescribing limited analgesics, such as dipyrone, in sub-therapeutic doses. In addition, there are few published studies or guidelines on the approach to the treatment of pain in patients with Chikungunya. Some groups of specialists from different fields have thus developed a protocol for the pharmacologic treatment of Chikungunya-associated acute and chronic joint pain; this will be presented in this review.

Clinical characteristics and outcomes of acute community acquired pneumonia in children at a reference public hospital in Pernambuco State, Brazil (2010-2011) / Características clínicas e desfechos de pneumonia comunitária aguda em crianças hospitalizadas em serviço público de referência de Pernambuco, Brasil (2010-2011)

Abstract Objectives: to describe the clinical characteristics and outcomes of acute community acquired pneumonia in children at a reference public hospital in Pernambuco State, Brazil (2010-2011) Methods: pneumonia case series of 80 children aged 28 days to 14 years old at Hospital da Restauração in Pernambuco, Brazil, from 2010 to 2011. Information was noted from medical files, and two comparison groups were created according to the severity of the disease, considering the presence of pleural effusion. Fisher or Mann-Whitney tests were used for comparative analyses. Results: severe pneumonia with pleural effusion was more frequent in children under five years of age (p=0,025), and was associated with longer period of fever (19 x 15 days) and coughing (17 x 13 days), when compared to non-complicated pneumonia cases. Six children (7,5%, 6/80) died, 50% before the fourth day of hospitalization (p=0,001). All deaths were from the pleural effusion group in children from the countryside (p=0,026). Conclusions: the severity of pneumonia in children attended at this hospital is related to younger children, and those transferred from the health units in the countryside, so, early diagnosis and medical intervention are limited by infrastructure and available resources for the health.

Resumo Objetivos: descrever as características clínicas e desfechos de pneumonia comunitária aguda em crianças assistidas em hospital público de referência no Estado de Pernambuco, Brasil (2010-2011). Métodos: série de casos de pneumonia em 80 crianças de 28 dias a 14 anos no Hospital da Restauração em Pernambuco, Brasil, entre maio de 2010 a 2011. As informações foram anotadas do registro hospitalar, sendo criado dois grupos de comparação de acordo com a gravidade da doença, considerando a presença ou não de derrame pleural. A análise comparativa utilizou os testes de Fisher ou Mann-Whitney. Resultados: pneumonia grave com derrame pleural foi mais frequente em menores de cinco anos (p=0,025), associado a maior período de febre (19 x 15 dias) e tosse (17 x 13 dias), compardo com casos de pneumonia não-complicada. Seis crianças (7,5%, 6/80) morreram. 50% antes do quarto dia de internação (p= 0,001). As mortes foram no grupo com derrame pleural, em crianças do interior do estado (p= 0,026). Conclusões: a gravidade da pneumonia em crianças atendidas neste hospital está relacionada a crianças menores, e naquelas transferidas de unidades de saúde do interior, cujo diagnóstico precoce e intervenção médica adequada são limitados pela infraestrutura e recursos disponíveis para a saúde.

Baixa renda como fator de proteção contra asma em crianças e adolescentes usuários do Sistema Único de Saúde / Low income as a protective factor against asthma in children and adolescents treated via the Brazilian Unified Health System

OBJETIVO: O estudo visou analisar o papel da baixa renda como fator de risco para o desenvolvimento de asma em crianças e adolescentes. MÉTODOS: Estudo de caso-controle com questionário. RESULTADOS: Foram estudados 687 participantes, de 5 a 15 anos de idade, usuários do Sistema Único de Saúde, em um hospital terciário, sendo 54,7 por cento masculinos. Quase metade (49,1 por cento) residia na zona metropolitana do Recife e o restante no interior. Moravam em casa de alvenaria 98,1 por cento, com média de 5,7 cômodos e 4,8 moradores. Suas mães estudaram em média 6,8 anos. A mediana da renda mensal per capita foi de R$ 103,75. Baseando-se na renda mensal per capita inferior a 25 e 50 por cento do salário mínimo, classificou-se a amostra em muito baixa renda, baixa renda e renda satisfatória, cujos percentuais foram, respectivamente: 39, 37,3 e 23,7. Não se observou associação entre baixa renda e desenvolvimento de asma. CONCLUSÕES: A baixa renda não exerce, em crianças e adolescentes usuários do Sistema Único de Saúde do nordeste do Brasil, efeito protetor no surgimento de asma, como poderia se supor, baseando-se na teoria da higiene. Todavia, estudos de coorte são necessários para confirmar estes achados.

OBJECTIVE: To analyze the role that low income plays in the development of asthma in children and adolescents. METHODS: A case-control study using a questionnaire. RESULTS: A total of 687 participants were studied at a tertiary hospital via the Brazilian Unified Health System. Ages ranged from 5 to 15 years, and 54.7 percent of the participants were male. Nearly half of the individuals (49.1 percent) lived in the metropolitan area of the city of Recife, and the remainder lived in the countryside. Most (98.1 percent) lived in concrete houses or apartments, with a mean of 5.7 rooms and 4.8 occupants per residence. Mean maternal level of education was 6.8 years of schooling. The median monthly per capita income was R$ 103.75 (Brazilian reals). The sample was stratified according to cut-off points related to the national minimum wage (R$350.00): <25 percent of minimum wage = very low income (39 percent of the sample); <50 percent of minimum wage = low income (37.3 percent of the sample); and >50 percent of minimum wage = satisfactory income (23.7 percent of the sample). There was no association between poverty and development of asthma. CONCLUSIONS: Poverty is not protective against asthma in children and adolescents treated via the Brazilian Unified Health System, as we might suppose based on the hygiene hypothesis. However, cohort studies are needed in order to confirm these findings.
