Estimation of changes in the force of infection for intestinal and urogenital schistosomiasis in countries with Schistosomiasis Control Initiative-assisted programmes
The last decade has seen an expansion of national schistosomiasis control programmes in Africa based on large-scale preventative chemotherapy. In many areas this has resulted in considerable reductions in infection and morbidity levels in treated individuals. In this paper, we quantify changes in the force of infection (FOI), defined here as the per (human) host parasite establishment rate, to ascertain the impact on transmission of some of these programmes under the umbrella of the Schistosomiasis Control Initiative (SCI)

Vasculopatia livedoide: uma doença cutùnea intrigante Livedoid vasculopathy: an intringuing cutaneous disease
A vasculopatia livedoide Ă© uma afecção cutĂąnea oclusiva dos vasos sanguĂneos da derme, de carĂĄter pauci-inflamatĂłrio ou nĂŁo-inflamatĂłrio. Caracteriza-se pela presença de lesĂ”es maculosas ou papulosas, eritĂȘmato-purpĂșricas, nas pernas, especialmente nos tornozelos e pĂ©s, as quais produzem ulceraçÔes intensamente dolorosas, que originam cicatrizes atrĂłficas esbranquiçadas, denominadas "atrofia branca". Nesta revisĂŁo, abordamos os estudos e relatos de caso da literatura mĂ©dica referentes Ă s associaçÔes etiopatogĂȘnicas da doença, particularmente as que se referem aos estados de trombofilia, seus achados histopatolĂłgicos e abordagens terapĂȘuticas empregadas na difĂcil condução clĂnica destes casos.<br>Livedoid vasculopathy is a skin disease that occludes the blood vessels of the dermis. It has a pauciinflammatory or non-inflammatory nature. It is characterized by the presence of macular or papular, erythematous-purpuric lesions affecting the legs, especially the ankles and feet, and producing intensely painful ulcerations, which cause white atrophic scars called "atrophie blanche". This review includes studies and case reports found in the medical literature regarding the etiopathogenic associations of the disease, particularly those related to thrombophilia, their histopathological findings and the therapeutic approaches used in the difficult clinical management of these cases
