RESUMO

Retinopathy in systemic lupus erythematosus generally consists of cotton-wool spots with or without intraretinal hemorrhages. Although rare, a more severe retinal vaso-occlusive disease, termed retinal vasculitis, has been described. We report data from 11 patients with SLE and severe retinal vaso-occlusive disease. Visual outcome was often poor, with 55% of the involved eyes suffering visual loss, frequently to an acuity of worse than 20/200. The systemic feature significantly associated with severe retinal vascular disease was central nervous system involvement (CNS lupus), present in eight (73%) of the 11 patients vs an overall prevalence of 37%. The association of CNS lupus with severe retinal vaso-occlusive disease probably reflects a similar pathogenetic mechanism and microangiopathy.

RESUMO

Adult male volunteers were orally vaccinated with two "killed" antityphoid preparations. The recommended doses of both vaccines resulted in serum antibody development in only a few of the subjects. When the dose of the monovalent preparation (Taboral) was doubled, serological responses occurred more frequently, with a rise in O agglutinins in nearly one-fifth of the subjects, in H agglutinins in approximately one-fourth, and in Vi antibodies in nearly half.When vaccinated volunteers were fed virulent typhoid organisms, disease occurred less frequently among those men vaccinated with Taboral at twice the recommended dose (38%) than among those not vaccinated (54%). This preparation did not confer protection at the recommended dose.Volunteers who had previously recovered from an induced typhoid infection received a further challenge with virulent organisms. These persons developed typhoid fever less frequently (23%) than individuals without prior typhoid exposure (30%).
