Evidence indicates that human T-cell lymphotropic virus type 1 (HTLV-1) infection leads to chronic immunosuppression and a greater susceptibility to infectious diseases. Spontaneous in vitro proliferation of peripheral blood mononuclear cells (PBMC) is an important immunological feature of HTLV-1-infected individuals. However, the association between spontaneous proliferation and immunosuppression is not clear. In this study, we evaluated the cellular immune responses of PBMC from 58 asymptomatic HTLV-1-infected individuals with PBMC showing or not showing spontaneous proliferation. Individuals with PBMC that spontaneously proliferated had increased proportions of CD4 T cells expressing CD45RO and dramatically reduced responses to recall antigens. In addition, frequencies of positive responses to recall antigens were also decreased in HTLV-infected individuals without spontaneous proliferation of PBMC. There was a polyclonal expansion of multiple T-cell receptor Vβ families of CD4 +...

A síndrome da veia cava superior (SVCS) é condição relativamente rara. Relatamos o caso de um paciente de 42 anos, masculino, hipertenso há 15 anos, que evoluiu com dor cervical e torácica há um um ano, sendo evidenciada oclusão de 95% da coronária direita. Submetido a angioplastia, porém com persistência da dor torácica. Posteriormente evoluiu com episódios recorrentes de hemiplegia à direita associados a crises hipertensivas, que melhoravam com medicamentos anti-hipertensivos. Pela presença de coloração vinhosa na face e acentuação durante os períodos de ataques isquêmicos transitórios, foi feita a suspeita diagnóstica de provável acometimento do sistema de drenagem venosa, confirmada à venografia pelo achado de dilatação da veia jugular direita e imagem de estreitamento importante na junção com a veia cava superior. Em conclusão, não foi possível definir com certeza a relação entre as duas patologias no caso aqui apresentado, porém chamou a atenção a melhora dos sintomas neurológ...

Charles Bonnet Syndrome (SCB) is defined by complex visual hallucinations in patients without cognitive impairment and ophthalmologic disease accompanied by reduced visual acuity. It has benign character, the patient is aware of the unreal nature of the phenomenon and has been reported mainly in the elderly. SCB is an important differential diagnosis of dementia syndromes, and its correct diagnosis has a great impact on patients' quality of life, who suffer from the stigma of psychiatric illness, failure of established therapies and the possibility of imminent cognitive decline. It is possible to avoid this negative impact by clarifying the syndrome. Hence the relevance of information diffusion and correct clinical diagnosis. Objective: In this context, an integrative literature review was conducted to better characterize the CBS, to contribute to the dissemination of knowledge about the subject. Methodology: for the selection of articles were used those available in PUBMED and ...
