Evaluation of an epidemic of sporotrichosis in cats: 347 cases (1998-2001).

Abstract: OBJECTIVE: To evaluate characteristics of a large epidemic of sporotrichosis in cats. DESIGN: Retrospective study. ANIMALS: 347 cats with naturally acquired infection with Sporothrix schenckii. PROCEDURE: Medical records were reviewed for data regarding clinical, mycologic, histopathologic, and routine hematologic and serum biochemical findings; assays for FIV-specific antibodies and FeLV antigen; antifungal treatment; and follow-up. RESULTS: Lesions varied from small papules to extensive zones of necrosis. Ten cats had no skin lesions, 114 had skin lesions at a single site, 86 had skin lesions in 2 sites, and 137 had skin lesions in 3 or more sites. Respiratory tract signs were observed in 154 cats and were the most frequent extracutaneous sign. Anemia, leukocytosis with neutrophilia, hypoalbuminemia, and hyperglobulinemia were the main blood abnormalities. Antibodies against FIV were detected in 28 cats, FeLV antigen was detected in 2 cats, and both were detected in 1 cat among 142 cats tested. During the study, 118 cats were lost to follow-up and 124 died. Of 266 cats that were treated, 68 were cured. Complete healing of the lesions was observed regardless of the presence of extracutaneous signs, general condition, treatment schedule, or coinfection with FIV. CONCLUSIONS AND CLINICAL RELEVANCE: Feline sporotrichosis was evident in subclinical to severe forms; however, cats can respond well to regular and prolonged antifungal treatment.

Isolation of Infective Zika Virus from Urine and Saliva of Patients in Brazil

Abstract: Zika virus (ZIKV) is an emergent threat provoking a worldwide explosive outbreak. Since January 2015, 41 countries reported autochthonous cases. In Brazil, an increase in Guillain-Barre syndrome and microcephaly cases was linked to ZIKV infections. A recent report describing low experimental transmission efficiency of its main putative vector, Ae. aegypti, in conjunction with apparent sexual transmission notifications prompted the investigation of other potential sources of viral dissemination. Urine and saliva have been previously established as useful tools in ZIKV diagnosis. However, no evidence regarding the infectivity of ZIKV particles present in saliva and urine has been obtained yet.

Major Expansion Of Primary Care In Brazil Linked To Decline In Unnecessary Hospitalization

Abstract: In 1994 Brazil launched what has since become the world’s largest community-based primary health care program. Under the Family Health Program, teams consisting of at least one physician, one nurse, a medical assistant, and four to six trained community health agents deliver most of their services at community-based clinics. They also make regular home visits and conduct neighborhood health promotion activities. This study finds that during 1999–2007, hospitalizations in Brazil for ambulatory care–sensitive chronic diseases, including cardiovascular disease, stroke, and asthma, fell at a rate that was statistically significant and almost twice the rate of decline in hospitalizations for all other causes. In municipalities with high Family Health Program enrollment, chronic disease hospitalization rates were 13 percent lower than in municipalities with low enrollment, when other factors were held constant. These results suggest that the Family Health Program has improved health system performance in Brazil...
