Abstract This report describes a case of multisystem inflammatory syndrome in a child that evolved with a pattern of toxic shock syndrome with coronary artery ectasia and neurological involvement, documented by magnetic resonance imaging, with changes in the corpus callosum and myopathy in the pelvic girdle and paravertebral musculature.

RESUMO OBJETIVO: O papilomavírus humano (HPV) é o vírus sexualmente transmissível mais prevalente no mundo, estando a infecção por este agente associada a um aumento do risco do câncer de colo uterino. A abordagem mais eficaz para o controle desse tipo de câncer continua sendo a triagem por meio do exame preventivo (Papanicolaou). Este estudo analisa o conhecimento de estudantes universitárias de cursos da área da saúde, bem como cursos de graduação de outras áreas do conhecimento com relação a questões importantes sobre o HPV. MÉTODO: Quatrocentas e setenta e três estudantes universitárias responderam a um questionário que avaliava os conhecimentos sobre a infecção pelo HPV, o câncer de colo do útero e o exame preventivo. Após análise descritiva, foi feita a análise multivariada por regressão logística para identificação dos fatores associados à informação sobre o HPV/câncer de colo do útero. RESULTADOS: O conhecimento das universitárias foi maior para questões simples relacionadas ao HPV e ao exame preventivo, mas foi menor para as correlações do HPV com verrugas genitais e com o câncer de colo do útero. Ser aluna da área da saúde e ter alta renda foram fatores associados ao maior conhecimento. Somente uma minoria das participantes reconheceu todas as situações que aumentavam o risco de infecção pelo HPV apresentadas no questionário. CONCLUSÃO: Os resultados evidenciam a necessidade de realização de campanhas educativas sobre a infecção pelo HPV, do seu potencial como agente de câncer do colo uterino e as formas de prevenção disponíveis.

SUMMARY OBJECTIVE: Human papillomavirus (HPV) is the most prevalent sexually transmitted virus in the world and is associated with an increased risk of cervical cancer. The most effective approach to cervical cancer control continues to be screening through the preventive Papanicolaou test (Pap test). This study analyzes the knowledge of university students of health science programs as well as undergraduate courses in other areas of knowledge on important questions regarding HPV. METHOD: Four hundred and seventy-three university students completed a questionnaire assessing their overall knowledge regarding HPV infection, cervical cancer, and the Pap test. A descriptive analysis is presented, and multivariate analysis using logistic regression identified factors associated with HPV/cervical cancer information. RESULTS: Knowledge was higher for simple HPV-related and Pap test questions but was lower for HPV interrelations with genital warts and cervical cancer. Being from the health science fields and having high income were factors associated with greater knowledge. Only the minority of the participants recognized all the situations that increased the risk of virus infection presented in the questionnaire. CONCLUSIONS: These findings highlight the need for educational campaigns regarding HPV infection, its potential as a cervical cancer agent and the forms of prevention available.

Age-related seroprevalence studies that have been conducted in Brazil have indicated a transition from a high to a medium endemicity of hepatitis A virus (HAV) infection in the population. However, most of these studies have focused on urban populations that experience lower incidence rates of HAV infection. In the current study, the prevalence of anti-HAV antibodies was investigated in children with a low socioeconomic status (SES) that live on the periphery of three capital cities in Brazil. A total of 1,162 dried blood spot samples were collected from individuals whose ages ranged from one-18 years and tested for anti-HAV antibodies. A large number of children under five years old (74.1-90%) were identified to be susceptible to HAV infection. The anti-HAV antibody prevalence reached ≥ 50% among those that were 10-14 years of age or older. The anti-HAV prevalence rates observed were characteristics of regions with intermediate level of hepatitis A endemicity. These data indicated that a large proportion of children with a low SES that live at the periphery of urban cities might be at risk of contracting an HAV infection. The hepatitis A vaccine that is currently offered in Brazil is only available for high-risk groups or at private clinics and is unaffordable for individuals with a lower SES. The results from this study suggest that the hepatitis A vaccine should be included in the Brazilian National Program for Immunisation.
