Bullous pemphigoid (BP) is an autoimmune, acquired, cutaneous disease caused by the production of autoantibodies against hemidesmosomes' components in the basement membrane. The estimated incidence in Europe ranges from 7 to 43 cases per million inhabitants per year. Several studies have reported an association between BP and neurological disorders (ND). Our cohort of Bullous pemphigoid and ND is the first in Brazil and showed a significantly high prevalence of neurological and/or psychiatric diseases, especially cerebrovascular accident (CVA) and dementia, in agreement with the prevalence reported in several studies published in the medical literature in recent years.

A 32-year-old HIV negative male presented with multiple pulmonary cavitation and skin abscesses up to 15 cm in diameter mimicking tuberculosis. Sporothrix brasiliensis was isolated and patient responded well to amphotericin B followed by itraconazole, except the skin lesions that had to be surgical drained to obtain cure.

A 57-year-old woman presented with periorbital ecchymoses, laxity in skin folds, polyneuropathy and bilateral carpal tunnel syndrome. A skin biopsy of the axillary lesion demonstrated fragmentation of elastic fibers, but with a negative von Kossa stain, consistent with cutis laxa. The diagnosis of primary systemic amyloidosis was made by the presence of amyloid material in the eyelid using histopathological techniques, besides this, the patient was also diagnosed with purpura, polyneuropathy, bilateral carpal tunnel syndrome and monoclonal gammopathy. She was diagnosed as suffering from multiple myeloma based on the finding of 40% plasma cells in the bone marrow, component M in the urine and anemia. The patient developed blisters with a clear content, confirmed as mucinosis by the histopathological exam. The final diagnoses were: primary systemic amyloidosis, acquired cutis laxa and mucinosis, all related to multiple myeloma.

The antagonists of tumor necrosis factor alpha (TNF-α) are increasingly being used in the treatment of inflammatory and autoimmune diseases. Several adverse effects of these drugs have been reported, including the paradoxical development of sarcoidosis, especially with the use of etanercept. We present the first Brazilian case report of systemic sarcoidosis induced by etanercept and a literature review.

Background: In Curitiba, systemic hypertension (SH) is the second leading cause of hospitalization and the leading cause of death from cardiovascular diseases. The protocols for the treatment of hypertension provide a systematic approach to patient management, aiming at improving the efficiency and quality of health services.
