The silicosis is the pneumoconiosis more frequent, resulting from the inhalation of silica or silicates containing mineral dust, mainly characterized by irreversible lung fibrosis. It is associated with the development of other diseases, including pulmonary tuberculosis, lung cancer and autoimmune diseases. The connective tissue disease after exposure to silica occurs usually after 15 years of initial exposure.The Erasmus syndrome describes the association of systemic sclerosis following exposure to silica with or without silicosis. The authors report two cases of patients with diagnosis of silicosis who developed systemic sclerosis.
Abstract:Trichophyton rubrum is a common agent found in superficial mycoses, which present ample nonin?ammatory lesions, with chronic evolution, especially in immunocompromised patients. The hypercortisolism in Cushing's syndrome increases the risk of infections as a result of the immunosuppressive effect of glucocorticoids. The reported cases here refer to two different types of dermatophytosis caused by Trichophyton rubrum in patients with Cushing's disease, resistant to antifungal treatment. The disease remitted after the levels of cortisol went back to normal. Keywords: Cushing's syndrome; Dermatomycoses; Immunosuppression; Onychomycosis Resumo: O dermatófito Trichophyton rubrum é um agente comum nas micoses superficiais, podendo apresentar lesões extensas pauci-inflamatórias de evolução crônica, especialmente em imunocomprometidos. O hipercortisolismo, na síndrome de Cushing, aumenta o risco de infecções, resultado do efeito imunossupressor dos glicocorticóides. Os casos relatados apresentam duas formas distintas de dermatofitose, em pacientes com doença de Cushing, causadas por Tricophyton rubrum e posterior remissão após normalização da cortisolemia.
Costello syndrome (CS) is a rare genetic disorder, first described by Costello in
1971, caused by mutations in the HRAS proto-oncogene. Clinical findings include
facial dysmorphism, skin disorders, cognitive impairment, cardiac and musculoskeletal
defects. There is an increased risk of malignancies in these patients, due to the
proto-oncogene mutation, and also sudden death secondary to heart disease. We report
a case with characteristic phenotype, highlighting the peculiar skin changes.
Pseudotumor cerebral é uma síndrome de hipertensão intracraniana na ausência de alargamento dos ventrículos, lesões expansivas ou qualquer outra causa estrutural. Medicamentos comumente utilizados na prática clínica da dermatologia estão associados ao desenvolvimento de pseudotumor cerebral, incluindo retinóides, tetraciclina e corticosteróides. Esta alteração deve ser suspeitada em qualquer paciente que desenvolva sintomas de hipertensão intracraniana enquanto está em uso de tais medicações. O reconhecimento precoce do quadro clínico é de grande importância, permitindo a suspensão imediata da droga, que é a principal conduta nestes casos. É apresentado um caso de pseudotumor cerebral associado ao uso de isotretinoína, com rápida identificação do quadro e tratamento adequado.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
