In high prevalence settings, histoplasmosis often revealed AIDS in severely immunodeficient and poorly followed patients. In the absence of a quick sensitive technique, skin smear and fungal tissue cultures are contributive. Nevertheless, given the diagnostic delays and the poor prognosis, presumptive treatment with amphotericin B-containing regimens should be recommended when clinical and epidemiological contexts are evocative.
Symptomatic macroglossia occurs in some rare congenital muscle diseases, such as Becker's and Duchenne's dystrophies or Pompe's disease. Herein we describe a case of symptomatic macroglossia with myositis of the tongue occurring in a patient with polymyositis. Tongue myositis was evidenced by dysarthria, frequent biting during mastication, swallowing difficulties without aspiration, and noisy breathing. Magnetic resonance imaging showed homogeneous hypertrophy of the tongue, especially the mouth's floor muscles. The diagnosis of tongue myositis was established by electromyography and biopsy. No other cause for the macroglossia was found. Symptoms resolved quickly with corticosteroid and intravenous immunoglobulin treatment. To our knowledge, this is the first reported case of symptomatic tongue myositis occurring in the course of polymyositis.
The effects of radiation on polymeric materials are a topic of concern in a wide range of industries including the sterilization, and the nuclear power industry. While much work has concentrated on systems like polyolefins that are radiation sterilized, some work has been done on epoxy systems. The epoxy system studied is an epoxy/amine paint which is representative of the paint that covers the inner surfaces of the French nuclear reactor containment buildings. In case of a severe accident on a Nuclear Power Plant, fission products can be released from the nuclear fuel to the reactor containment building. Among them, volatile iodine (I) can be produced and can interact with the epoxy-paint. This paint is also subjected to gamma radiation damages (due to the high dose in the containment coming from radionuclides released from the fuel). So the epoxy-paint studied was exposed to gamma radiation under air atmosphere after being loaded with I or not. The aim of this study is to characterize by FTIR spectroscopy the iodine-paint interactions, then to identify the radiation damages on the epoxy-paint, and to check their effects on these iodine-paint interactions. This work shows the potential of multi-block analysis method (ANOVA-PCA and COMDIM = AComDim) for such a study as it allows to identify the nature of iodine/epoxy-paint interactions and to characterize the gamma radiation damages on the epoxy-paint. AComDim method conduces to the extraction of Common Components to different tables and highlights factors of influence and their interactions.
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.
