ABSTRACT Gain-of-function mutations in the STAT1 gene have been initially associated with chronic mucocutaneous candidiasis. However, further research has shown that STAT1 GOF variants may increase susceptibility to infection by other intracellular pathogens. This report describes the first case of disseminated leishmaniasis associated with a STAT1 GOF mutation in a pediatric patient who did not have chronic mucocutaneous candidiasis. The patient was a four-year-old boy presenting with fever, severe asthenia, hepatosplenomegaly, pancytopenia, and liver failure. Bone marrow aspirate revealed hemophagocytosis and Leishmania parasites. Treatment consisted primarily of liposomal amphotericin B, as per the Hemophagocytic Lymphohistiocytosis 2004 protocol. After eight weeks of treatment, the patient did not improve and was submitted to diagnostic splenectomy. Activated macrophages and nodular spleen necrosis secondary to the visceral leishmaniasis were detected. Unfortunately, the patient died in the second week after splenectomy due to overwhelming systemic infection. DNA sequencing revealed a pathogenic (p. R274Q) GOF mutation in STAT1.

ABSTRACT Zika virus (ZIKV) is an emergent flavivirus transmitted mainly through Aedes spp. mosquitoes that is posing challenge to healthcare services in countries experiencing an outbreak. Usually ZIKV infection is mild, but in some cases it has been reported to progress into neurological diseases such as microcephaly in infants and Guillain-Barré syndrome (GBS) in adults. GBS is a debilitating autoimmune disorder that affects peripheral nerves. Since ZIKV caused massive outbreaks in South America in the past few years, we aimed to systematically review the literature and perform a meta-analysis to estimate the prevalence of GBS among ZIKV-infected individuals. We searched PubMed and Cochrane databases and selected three studies for a meta-analysis. We estimated the prevalence of ZIKV-associated GBS to be 1.23% (95% CI = 1.17–1.29%). Limitations include paucity of data regarding previous flavivirus infections and ZIKV-infection confirmation issues. Our estimate seems to be low, but cannot be ignored, since ZIKV outbreaks affects an overwhelming number of individuals and GBS is a life-threatening debilitating condition, especially in pregnant women. ZIKV infection cases must be closely followed to assure prompt care to reduce the impact of GBS associated-sequelae on the quality of life of those affected.

RESUMO Objetivo Analisar os significados atribuídos pelos pacientes à vivência das visitas médicas realizadas em grupo à beira do leito na enfermaria de Clínica Médica. Método Utilizou-se o método qualitativo, por meio da técnica de entrevistas semiestruturadas. Foram entrevistados 11 pacientes, internados em um hospital-escola localizado no Recife. As entrevistas foram submetidas à técnica de análise de conteúdo, e as categorias analíticas foram embasadas na psicologia da saúde, com enfoque biopsicossocial. Resultados e discussão Os entrevistados perceberam a visita como algo bom, que auxilia na aprendizagem dos estudantes, porém alguns a consideraram algo negativo e desconhecido. Os participantes interpretaram a visita como um espaço dos médicos, do qual eles não devem participar, sendo a comunicação centrada nos médicos e estudantes. Essa postura pode desfavorecer a construção do vínculo médico-paciente e contribuir para um sentimento de passividade dos pacientes. Conclusão Embora a maioria dos pacientes tenha avaliado a visita médica de forma positiva, como a comunicação está centrada nos médicos-estudantes, limita-se a participação do paciente durante a visita médica.

ABSTRACT Objective To analyze the meanings attributed to the experience of bedside teaching in groups on hospital wards. Methods This research used a qualitative method with semi-structured interviews. The sample was composed of eleven patients hospitalized in a hospital in Recife. The interviews were subjected to content analysis and the formation of the categories was based on health psychology, employing a biopsychosocial approach. Results and discussion The participants perceived the bedside teaching as a good thing, which helps the students’ learning, but some considered it as negative and unfamiliar. Furthermore, the participants interpreted the bedside teaching as a space for physicians, in which they should not participate, where communication is centered on the student doctors. This attitude may not favor the construction of the doctor-patient relationship and, thus, contribute to a feeling of passivity among patients. Conclusion Although most the patients evaluated the bedside teaching positively, since communication was focused on the student doctors, it limited the patients’ participation during the activity.

OBJETIVO: analisar, em mulheres com HPV em colo do útero, as características da infecção viral e os fatores de risco para lesão intraepitelial de alto grau e carcinoma cervical. MÉTODOS: realizou-se um estudo caso-controle com mulheres com HPV em colo do útero atendidas em serviço de Ginecologia de referência vinculado ao SUS, em Recife, Nordeste do Brasil. No grupo de casos (72 mulheres com lesão intraepitelial de alto grau ou carcinoma cervical) e de controles (176 mulheres com colpocitologia normal ou com alterações benignas), foram pesquisados seis genótipos virais (HPV 16, 18, 31, 33, 6 e 11) em material da ecto- e endocérvice com primers MY09/MY11. As variáveis independentes foram hierarquizadas em três níveis de determinação: distal (sociodemográficas), intermediário (comportamentais) e proximal (realização anterior de colpocitologia). A homogeneidade das proporções foi testada (χ2). Obtiveram-se ORs não ajustadas e, na modelagem final, realizou-se regressão logística hierarquizada com o ajuste do efeito de cada variável sobre o desfecho pelas variáveis do mesmo nível e de níveis anteriores de causalidade. RESULTADOS: em 76,6% das 248 mulheres participantes do estudo, o genótipo viral da infecção cervical foi identificado. Predominaram genótipos de alto risco oncogênico (83,4% nos casos e 67,1% nos controles), principalmente HPV 16 e 31. Foram identificados como fatores de risco (a) distais: residir em zona rural (OR=2,7; IC95%: 1,1-6,2), menos de três anos de estudo (OR=3,9; IC95%: 2,0-7,5) e renda familiar inferior a dois salários mínimos (OR=3,3; IC95%: 1,0-10,5); (b) intermediário: número de gestações igual ou superior a quatro (OR=2,0; IC95%: 1,0-3,7); (c) proximal: ausência de colpocitologia anterior (OR=9,7; IC95%: 2,4-38,2). CONCLUSÕES: em mulheres usuárias do SUS do Nordeste do Brasil predominam os genótipos virais 16 e 31 em infecções cervicais por HPV, sendo que fatores socioeconômicos, reprodutivos e relacionados à ausência de rastreamento citológico representam risco para lesão intraepitelial de alto grau e câncer cervical.

PURPOSE: to analyze the characteristics of viral infection and the risk factors for high-grade squamous intraepithelial lesion and cervical carcinoma in women with cervical HPV infection. METHODS: a case-control study was conducted on women with cervical HPV at a Gynecology reference service enrolled at the Public Health System, located in Recife, Northeastern Brazil. The groups of cases (72 women with high-grade squamous intraepithelial lesion or cervical cancer) and controls (176 women with normal Pap smear or benign alterations) were investigated for six viral genotypes (HPV 16, 18, 31, 33, 6, 11) in ecto- and endocervical material using MY09/MY11 primers. The independent variables were ranked in three levels of determination: distal (sociodemographic), intermediate (behavioral) and proximal (previous Pap smear). The homogeneity of proportions was tested (χ2), unadjusted Odds Ratios (OR) were obtained and hierarchical logistic regression was applied to the final model, with adjustment of the effect of each variable to the outcome based on the variables in the same and previous levels of causality. RESULTS: the viral genotype of cervical infection was identified in 76.6% of the 248 women participating in the study. High-risk HPV genotypes (83.4% of cases and 67.1% of controls) were predominant, especially HPV 16 and 31. The distal risk factors identified were: living in a rural area (OR=2.71, 95%CI: 1.18-6.23), less than three years of study (OR=3.97, 95%CI: 2.09-7.54) and family income below two minimum wages (OR=3.30, 95%CI: 1.04-10.51); intermediate: four or more pregnancies (OR=2.00, 95%CI: 1.06-3.76); and proximal: absence of a previous Pap smear (OR=9.74, 95%CI: 2.48-38.28). CONCLUSIONS: genotypes 16 and 31 of cervical HPV infection are predominant among women assisted by the Public Health System in Northeastern Brazil. Socioeconomic and reproductive factors, as well as the absence of cytological screening, represent risk factors for the progression of infection to high-grade squamous intraepithelial lesion and cervical cancer.

OBJETIVOS: determinar a prevalência da testagem anti-HIV no pré-natal e internamento para o parto e identificar fatores associados à realização e recebimento do resultado dos testes em parturientes. MÉTODOS: estudo descritivo, com 400 puérperas atendidas no Centro de Atenção à Mulher do IMIP Instituto Materno Infantil Prof. Fernando Figueira, IMIP. RESULTADOS: chegaram à admissão para o parto sem o resultado do teste anti-HIV, 154 (38,5%) mulheres. Dessas, foi solicitado "teste rápido" em 134 (87,0%), porém só foram colhidos em 130 (84,5%). Observou-se que: o número de consultas realizadas no pré-natal, (p=0,001) o número de profissionais que atenderam a mulher no pré-natal e a escolaridade (p=0,006) tiveram associação significativa com a realização do exame anti-HIV no pré-natal, mas não com o recebimento do mesmo. O aconselhamento e oferecimento do teste tanto no pré-natal como na admissão para o parto também apresentaram associação significativa com a realização do anti-HIV durante o pré-natal. CONCLUSÕES: a prevalência de testagem anti-HIV no pré-natal e/ou na triagem foi satisfatório no aspecto quantitativo, porém o recebimento do resultado tanto no pré-natal quanto na admissão para o parto , bem como o aconselhamento pós-teste, foi aquém do recomendado.

OBJECTIVES: to determine HIV testing prevalence during antenatal care and hospital admission for delivery and identify factors associated to pregnant women testing and results delivery. METHODS: a descriptive study comprised of 400 puerperal women seen at the Women Care Center of Instituto Materno Infantil Professor Fernando Figueira, IMIP. RESULTS: one hundred and fifty four (38.5%) women were admitted for delivery without having received the results of the anti-HIV test. One hundred and thirty four women (87.0%) had been prescribed a "fast HIV test" but only 130 were tested (84.5%). The following was determined: the number of antenatal medical visits ((p<0,001), the number of professionals providing antenatal care and education level (p=0,006) were significantly associated to anti-HIV testing during antenatal care, but not with results delivery. Counseling and test access during antenatal care and hospital admission for delivery were significantly associated to anti-HIV testing during antenatal care as well. CONCLUSIONS: anti-HIV testing prevalence during antenatal care and/or screening was satisfactory in quantitative terms, however, results delivery during antenatal care, admission for delivery, and post-test counseling fell short of recommendations.

Estudou-se a incidência da Entamoeba histolytica entre aidéticos homossexuais masculinos com o objetivo de determinar se entre esses pacientes o protozoário, incapaz de produzir doença na população geral do Recife, causaria amebíase invasiva. Dos 77 pacientes incluídos na investigação, apenas um (1,3%) albergava a E. histolytica. A eletroforese em gel de amido da linhagem, isolada mostrou um perfil de isoenzimas compatível com o zimodema 1, não patogênico. Além disso, nenhum dos pacientes examinados apresentou no soro anticorpos anti-ameba, verificados pelos testes de precipitação em ágar e imunoenzimático. Estes resultados mostraram que, mesmo entre indivíduos de sistema imunológico comprometido, as linhagens de E. histolytica prevalentes no Recife carecem de potencialidades patogênicas. Não se justifica, portanto, o emprego do metronidazol nos portadores de cistos de ameba, sejam eles aidéticos ou não.

The purpose of this paper was to determine if among male homosexual SIDA patients, the Entamoeba histolytica was able to product invasive illness. From the 77 investigated patients only one (1.3%) has cysts of E. histolytica in his stools. Tide electroforesis of the only isolated strain has shown it was from zimodeme I, non pathogenic. Tloe research of antimebic antibodies was negative in the serum of the totality of patients. Those results showed that even in immunocompromissed patients with SIDA, E. histolytica strain found in Recife ivas not able to produce disease. The utilization of metronidazol is not indicated in amoebic cysts carriers.
