SUMMARY Atopic dermatitis is a common skin disease. Its increased incidence has changed the focus of research on atopic dermatitis toward epidemiology, prevention, and treatment. Evidence suggests that intestinal microbiota plays an important role in the pathogenesis of atopic dermatitis inducing immunosuppression, but its exact mechanism is still unclear. Probiotics have been widely reported to act on the immune system. They are living microorganisms with immunomodulatory effects that stimulate Th1 cytokines and suppress the Th2 response, which are being researched for the treatment of several diseases. Probiotics most commonly used are part of the intestinal microflora like lactobacilli, bifidobacteria, and enterococci. We describe here a case of evident response to the use of probiotics in a girl with severe atopic dermatitis, with a significant change in severity scores of atopic dermatitis (BSA/SCORAD/FDLQI). Modulation of the intestinal microbiota with probiotics may offer a way to prevent or treat allergic diseases, including atopic dermatitis.
An unusual case of chronic pulmonary paracoccidiodomycosis and disseminated cryptococcosis in a non-HIV infected patient is reported in a 72-year-old previously healthy man. A chest radiograph disclosed a bilateral diffused interstitial infiltrate involving middle and lower lung fields. Specimen samples taken from the tracheal tube revealed yeast-like organisms suggestive of Cryptococcus neoformans and Paracoccidiodes brasiliensis. Blood and cerebrospinal fluid culture was positive for C. neoformans and the immunodiffusion test against paracoccidiodin revealed a precipitation band. The patient died 24 days after the admission.
Recurrent pneumonia may be defined as two episodes of pneumonia in a single year, or as three or more episodes in any given period.(1) The diagnosis should be established upon clinical remission and confirmation of complete radiological resolution between two episodes of infection.The etiology of recurrent pneumonia is varied and includes endobronchial obstruction, extrinsic compression of airways and structural abnormalities, ABSTRACTRecurrent pneumonia is characterized by frequent infection and infiltrates in one or more lung lobes. The localized form of the disease is caused by intraluminal obstruction, extrinsic compression or structural abnormalities. The pattern, frequency and severity of the infections, together with a thorough review of all chest X-rays, inform the diagnosis. Herein, we report a case of recurrent pneumonia due to endobronchial obstruction by mucoepidermoid carcinoma.
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.
