Background: Two aspects need to be considered for schistosomiasis control: morbidity and transmission. In this context, many soluble substances have been tested and Euphorbia milii latex is one of the most promising Brazilian molluscicides. Phytochemical studies involving simulation of the applicability of this latex on all aquatic forms of the S. mansoni life cycle are rare in the literature. ...

BACKGROUND Numerous factors may influence Schistosoma infection intensity and prevalence within endemic communities, including exposure-related factors such as local environment and behaviour, and factors relating to susceptibility to infection such as immunology and genetics. While animal studies performed in the laboratory can be tightly controlled, human populations are highly heterogeneous,...

Background: Topical corticosteroids are currently used for treatment of diaper dermatitis. Previous studies have shown the efficacy of sucralfate in the treatment of diaper dermatitis and contact dermatitis in peri-stomy areas. Objectives: To evaluate the efficacy of topical sucralfate in comparison with hydrocortisone cream in the treatment of diaper dermatitis. Patients and Methods: In a doub...

Background: Atopic dermatitis is the most common chronic inflammatory dermatitis, due to immunological disorders. Patients with atopic dermatitis are prone to infectious diseases including bacterial infections. On the other hand, atopy may be protective against helminthes parasites. The objective of this study was to compare the frequency and clinical presentations of cutaneous leishmaniasis in...

Climate changes, particularly global warming, are likely to impact host–parasite interactions. However, our understanding of the effects of environmental factors on marine host–parasite systems is limited. We conducted a series of laboratory experiments on the effects of temperature on all transmission steps of the intertidal trematode Maritrema novaezealandensis from its first intermediate sna...

The excretory bladder epithelium of the Ochetosoma aniarum (Leidy, 1891) metacercaria undergoes drastic morphological changes within 24 hours of cercanal penetration into tadpoles. The previously smooth luminal surface develops numerous folds and lamellar structures. The spongiform granules so common in cercariae disappear, and simultaneously calcareous concretion formation begins. The concreti...

Cercariae, the freshwater stage of Schistosoma mansoni infectious to man, are covered by a single unit membrane and an immunogenic glycocalyx. When cercariae penetrate the host skin, they transform to schistosomula by shedding tails, secreting mucous and enzymes, and forming microvilli over their surface. Here the loss of the glycocalyx from cercariae transforming in vitro was studied morpholog...

background: occupational contact dermatitis, especially in hand, is one of the most common occupational disorders. the present study aimed at evaluating patients with occupational allergic contact dermatitis (acd) caused by common allergens based on occupation type and disease history.   methods: this cross-sectional study aimed at evaluating the data of the patients with probable diagnosis of ...
