Sarcoid granulomas can be found in a wide range of diseases and differentiating sarcoidosis from a sarcoid-like reaction may be a challenge. We present a woman with erythematoviolaceous papulonodular lesions located on the ears where piercings were placed. A skin biopsy showing an infiltrate of sarcoid and focal tuberculoid granulomas did not exclude sarcoidosis. There was a slight increase in the level of angi...
Nos últimos anos vários estudos demonstraram a implicação da microbiota intestinal em várias doenças de mediação imune como a diabetes, a colite ulcerosa e a esclerose múltipla. Existem poucos dados sobre o microbioma folicular e o seu papel na patogénese de doenças que afetam o couro cabeludo, sendo uma área de investigação crescente. Alguns estudos mostram influência da disbiose nestas doenças...
ABSTRACT: Residues of Cistus ladanifer obtained after commercial steam distillation for essential oil production were evaluated to produce cellulose enriched solids and added-value lignin-derived compounds. The delignification of extracted (CLRext) and extracted and hydrothermally pretreated biomass (CLRtreat) was studied using two organosolv processes, ethanol/water mixtures (EO), and alkali-catalyzed glycerol...
Residues of Cistus ladanifer obtained after commercial steam distillation for essential oil production were evaluated to produce cellulose enriched solids and added-value lignin-derived compounds. The delignification of extracted (CLRext) and extracted and hydrothermally pretreated biomass (CLRtreat) was studied using two organosolv processes, ethanol/water mixtures (EO), and alkali-catalyzed glycerol (AGO), an...
Photosensitivity is characterized by an abnormal response to non-ionizing radiation, disclosing a variety of morphological patterns, which reflect their different etiologies. We describe the case of a man presenting with a photosensitive dermatosis with no apparent exogenous cause and refractory to multiple treatments. Phototests revealed a reduction in minimal erythema dose to UVB. Laboratory tests in order to...
.; Apresenta-se o caso de uma mulher de 75 anos, caucasiana, com achados clínicos compatíveis com sialadenite esclerosante crónica e discutem-se os achados laboratoriais, histológicos e radiológicos que permitiram estabelecer o diagnóstico de uma Doença relacionada com IgG4. Discutem-se os critérios de diagnóstico, tratamento e evolução clínca da doente.
