Visceral leishmaniasis caused by Leishmania (Viannia) braziliensis in a patient infected with human immunodeficiency virus

The current article reports the case of a 19-month-old-girl, from the state of Minas Gerais, Brazil, with visceral leishmaniasis, by Leishmania (Viannia) braziliensis, and Human Immunodeficiency Virus (HIV) co-infection. The child's mother and father, aged 22 and 27 years old, respectively, were both HIV positive. The child was admitted to the General Pediatric Center, in Belo Horizonte, presenting high fever, fatigue, weight loss and enlargement of liver and spleen. Indirect immunofluorescent test revealed a titer of 1:320 for Leishmania. Such result was confirmed by the presence of amastigotes in bone marrow aspirate samples and culture of promastigote forms. Parasites were identified as being Leishmania (Viannia) braziliensis through PCR, using a L. braziliensis complex primer and a generic primer, followed by hibridization. Specific leishmaniasis therapy (GlucantimeÒ antimonial) was intravenously administered.

Avaliação das necessidades educacionais dos cuidadores de pessoas com esquizofrenia: contribuição para a validação de um questionário

RESUMO: Os programas psicoeducacionais para cuidadores de pessoas com esquizofrenia são muitas vezes construídos sem terem em conta as necessidades educacionais destes utilizadores dos serviços de saúde mental. Apresenta-se uma revisão da literatura sobre esquizofrenia, família, intervenções familiares e avaliação de necessidades educacionais. Conduziu-se um estudo transversal descritivo com características exploratórias numa amostra de conveniência de principais cuidadores (N=74) de pessoas com esquizofrenia em tratamento no Departamento de Psiquiatria e Saúde Mental do Hospital de S. Francisco Xavier. A metodologia utilizada é do tipo qualitativo e quantitativo. Objectivos: Descrever as características de uma amostra de principais cuidadores de pessoas com esquizofrenia e as suas necessidades educacionais, bem como contribuir para a validação do Educational Needs Questionnaire (ENQ). Instrumentos: Educational Needs Questionnaire (ENQ) e Inventário Sócio-Demográfico para Familiares (RSDS). Resultados: O doente com esquizofrenia é cuidado sobretudo pela família, sendo as mães os cuidadores por excelência. Trata-se de mulheres idosas que cuidam do doente há muitos anos e que necessitam saber mais sobre como obter ajuda dos serviços de saúde mental. Conclusões: Os cuidadores sentem que os serviços de saúde mental não lhes dão o apoio de que necessitam e estão preocupados sobretudo com o estigma e com o que acontecerá aos seus doentes após a sua morte. A versão portuguesa do ENQ mostrou possuir boa fiabilidade, recomendando-se o desenvolvimento de estudos que dêem continuidade ao esforço de validação aqui iniciado.-------------ABSTRACT: The psychoeducational programs for caregivers of people with schizophrenia are often built without regard for the educational needs of users of mental health services. We present a review of the literature on schizophrenia, family, family interventions and evaluation of educational needs. We conducted a cross-sectional study with exploratory characteristics in a convenience sample of primary caregivers (N = 74) of people with schizophrenia being treated in the Department of Psychiatry and Mental Health at the Hospital of St. Francisco Xavier. We used a qualitative and quantitative methodology. Objectives: To describe the characteristics of a sample of primary caregivers of people with schizophrenia and their educational needs, as well as contribute to the validation of the Educational Needs Questionnaire (ENQ). Instruments: Educational Needs Questionnaire (ENQ) and Inventário Sócio-Demográfico para Familiares (RSDS). Results: Patients with schizophrenia are cared by the family, mothers are the caregivers for excellence. They are older women who take care of the patient for many years and they need to know more about how to get help from mental health services. Conclusions: Caregivers feel that mental health services don‟t give them the support they need and they are especially worried about the stigma and what will happens to their patients after their death. The Portuguese version of the ENQ proved to have good reliability and we recommend the development of studies that give continuity to the validation effort here started.

Primary cutaneous cryptococcosis due to Cryptococcus neoformans var. gattii serotype B, in an immunocompetent patient

The authors report a male patient, a seller with no detected immunosuppression, with an extensive ulcerated skin lesion localized on the left forearm, caused by Cryptococcus neoformans var. gattii serotype B. Oral treatment with fluconazole was successful. A review of the literature showed the rarity of this localization in HIV-negative patients. In contrast, skin lesions frequently occurs in HIV-positive patients, with Cryptococcus neoformans var. neoformans serotype A predominating as the etiological agent. In this paper, the pathogenicity of C. neoformans to skin lesions in patients immunocompromised or not, is discussed, showing the efficacy of fluconazole for the treatment of these processes.

Histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis) in an HIV-positive patient

Histiocytic necrotizing lymphadenitis, or Kikuchi's lymphadenitis (KL), is an unusual form of lymphadenitis, generally with self-limited clinical course. KL has been reported in rare patients infected with the human immunodeficiency virus (HIV). Pathogenesis of the lesion is probably related to an impaired immune function. The purpose of the present article is to report on one case in which KL was diagnosed in an HIV-infected patient. Histomorphology and immunophenotype were similar to previous reports, but a focus of activated CD30+ macrophages was seen, what might be due to the immunological status of the patient. EBV was not detected on the sections using the in situ hybridization technique. Although rare, the occurrence of KL in HIV-infected subjects must be emphasized, because of the potential misdiagnosis of malignancy, especially in the presence of CD30+ cells.

Tuberculous brain abscess in a patient with AIDS: case report and literature review

Tuberculous brain abscesses in AIDS patients are considered rare with only eight cases reported in the literature. We describe the case of a 34-year-old woman with AIDS and previous toxoplasmic encephalitis who was admitted due to headache and seizures. A brain computed tomography scan disclosed a frontal hypodense lesion with a contrast ring enhancement. Brain abscess was suspected and she underwent a lesion puncture through a trepanation. The material extracted was purulent and the acid-fast smear was markedly positive. Timely medical and surgical approaches allowed a good outcome. Tuberculous abscesses should be considered in the differential diagnosis of focal brain lesions in AIDS patients. Surgical excision or stereotactic aspiration, and antituberculous treatment are the mainstay in the management of these uncommon lesions.

The patient safety journey in Portugal : challenges and opportunities from a public health perspective

ABSTRACT - Despite improvements in healthcare interventions, the incidence of adverse events and other patient safety problems constitutes a major contributor to the global burden of diseases and a concern for Public Health. In the last years there have been some successful individual and institutional efforts to approach patient safety issues in Portugal, unless such effort has been fragmented or focused on specific small areas. Long-term and global improvement has remained elusive, and most of all the improvement of patient safety in Portugal, must evaluate not only the efficacy of a change but also what was effective for implementing the change. Clearly, patient safety issues result from various combinations of individual, team, organization, system and patient factors. A systemic and integrated approach to promote patient safety must acknowledge and strive to understand the complexity of work systems and processes in health care, including the interactions between people, technology, and the environment. Safety errors cannot be productively attributed to a single human error. Our objective with this paper is to provide a brief overview of the status quo in patient safety in Portugal, highlighting key aspects that should be taken into account in the design of a strategy for improving patient safety. With these key aspects in mind, policy makers and implementers can move forward and make better decisions about which changes should be made and about the way the needed changes to improve patient safety should be implemented. The contribution of colleagues that are international leaders on healthcare quality and patient safety may also contribute to more innovative research methods needed to create the knowledge that promotes less costly successful changes.---- ---------------------- RESUMO – As questões relacionadas com a Segurança do Doente, e em particular, com a ocorrência de eventos adversos tem constituído, de há uns tempos a esta parte, uma crescente preocupação para as organizações de saúde, para os decisores políticos, para os profissionais de saúde e para os doentes/utentes e suas famílias, sendo por isso considerado um problema de Saúde Pública a que urge dar resposta. Em Portugal, nos últimos anos, têm sido desenvolvidos esforços baseados, maioritariamente, em iniciativas isoladas, para abordar os aspectos da Segurança do Doente. O facto de essas iniciativas não serem integradas numa estratégia explícita e de dimensão regional ou nacional, faz com que os resultados sejam parcelares e tenham visibilidade reduzida. Paralelamente, a melhoria da qualidade dos cuidados de saúde (a longo prazo) resultante dessas iniciativas tem sido esparsa e nem sempre a avaliação tem sido feita tendo em conta critérios de efectividade e de eficiência. A Segurança do Doente resulta da interacção de diversos factores relacionados, por um lado, com o doente e, por outro, com a prestação de cuidados que envolvem elementos de natureza individual (falhas activas) e organizacional/estrutural (falhas latentes). Devido à multifactorialidade que está na base de «problemas/falhas» na Segurança do Doente, qualquer abordagem a considerar deve ser sistémica e integrada. Simultaneamente, tais abordagens devem contemplar a compreensão da complexidade dos sistemas e dos processos de prestação de cuidados de saúde e as suas interdependências (envolvendo aspectos individuais, tecnológicos e ambientais). O presente trabalho tem por objectivo reflectir sobre o «estado da arte» da Segurança do Doente em Portugal, destacando os elementos-chave que se consideram decisivos para uma estratégia de acção nesse domínio. Com esses elementos os responsáveis pela governação da saúde poderão valorizar os aspectos que consideram decisivos para uma política de Segurança do Doente mais eficaz. A contribuição de quatro colegas internacionalmente reconhecidos como líderes na área da Qualidade em Saúde e da Segurança do Doente, constitui, por certo, uma oportunidade ímpar para a identificação e discussão de alguns dos principais desafios, ameaças e oportunidades que s

Cerebral mass lesion due to cytomegalovirus in a patient with AIDS: case report and literature review

Cytomegalovirus (CMV) disease in acquired immunodeficiency syndrome (AIDS) patients most commonly presents as chorioretinitis and gastro-intestinal infection. Neurological involvement due to CMV may cause several clinical presentations: polyradiculitis, myelitis, encephalitis, ventriculo-encephalitis, and mononeuritis multiplex. Rarely, cerebral mass lesion is described. We report a 39 year-old woman with AIDS and previous cerebral toxoplasmosis. She presented with fever, seizures, and vulval ulcers. Her chest X-ray showed multiple lung nodules, and a large frontal lobe lesion was seen in a brain computed tomography scan. She underwent a brain biopsy through a frontal craniotomy, but her condition deteriorated and she died in the first postoperative day. Histopathological studies and immunohistochemistry disclosed CMV disease, and there was no evidence of cerebral toxoplasmosis, bacterial, mycobacterial or fungal infection. CMV disease should be considered in the differential diagnosis of cerebral mass lesion in AIDS patients. High suspicion index, timely diagnostic procedures (surgical or minimally invasive), and proper utilization of prophylactic and therapeutic medication could improve outcome of these patients.

Disseminated paracoccidioidomycosis with peripleuritis in an AIDS patient

Paracoccidioidomycosis is one of the most frequent systemic and endemic mycoses of Latin America caused by a dimorphic fungus. In AIDS patients, paracoccidioidomycosis appears as a severe and disseminated disease with a wide spectrum of clinical findings. The CD4 counts are usually less than 200 cell/mu L. We present a case of disseminated paracoccidioidomycosis with peripleuritis and subcutaneous abscesses on the chest wall as initial manifestation of AIDS. In endemic countries, paracoccidioidomycosis should be included as an opportunistic infection in AIDS.

Determination of human cytomegalovirus genetic diversity in different patient populations in Costa Rica

Seroprevalence of HCMV in Costa Rica is greater than 95% in adults; primary infections occur early in life and is the most frequent congenital infection in newborns. The objectives of this study were to determine the genetic variability and genotypes of HCMV gB gene in Costa Rica. Samples were collected from alcoholics, pregnant women, blood donors, AIDS patients, hematology-oncology (HO) children and HCMV isolates from neonates with cytomegalic inclusion disease. A semi-nested PCR system was used to obtain a product of 293-296 bp of the gB gene to be analyzed by Single Stranded Conformational Polymorphism (SSCP) and sequencing to determine the genetic polymorphic pattern and genotypes, respectively. AIDS patients showed the highest polymorphic diversity with 14 different patterns while fifty-six percent of HO children samples showed the same polymorphic pattern, suggesting in this group a possible nosocomial infection. In neonates three genotypes (gB1, gB2 and gB3), were determined while AIDS patients and blood donors only showed one (gB2). Of all samples analyzed only genotypes gB1, 2 and 3 were determined, genotype gB2 was the most frequent (73%) and mixed infections were not detected. The results of the study indicate that SSCP could be an important tool to detect HCMV intra-hospital infections and suggests a need to include additional study populations to better determine the genotype diversity and prevalence.

Salmonella enterica subsp houtenae serogroup O:16 in a HIV positive patient: case report

We described a case of salmonellosis in a 33-year old HIV-infected patient. The patient presented oral and esophageal candidiasis, intense epigastric and retrosternal pain. During the physical examination he was hypochloraemic, acyanotic, hypohydrated, anicteric and afebrile. Admittance laboratorial tests indicated: red cells 3.6 millions/mm³; hemoglobin, 10.1 g/dL; leukocyte count, 3,000/mm³, with 1% of eosinophils, 14% of non-segmented and 53% of segmented neutrophils and 31% of lymphocytes. The blood culture was positive for Salmonella enterica subsp houtenae serogroup O:16. This is probably the first human report of bacteremia due to Salmonella enterica subsp houtenae in Brazil associated to HIV-infected patient.
