Consensus on the diagnostic and therapeutic management of chronic spontaneous urticaria in adults - Brazilian Society of Dermatology.

Background: Urticarias are frequent diseases, with 15% to 20% of the population presenting at least one acute episode in their lifetime. Urticaria are classified in acute ( ≤ 6 weeks) or chronic (> 6 weeks). They may be induced or spontaneous.

Clinical and laboratory characteristics, staging, and outcomes of individuals with AIDS-associated Kaposi's sarcoma at an university hospital.

Background:: Kaposi's sarcoma continues to be the most common human immunodeficiency virus - associated neoplasm with considerable morbidity and mortality.

Objective:: To describe the clinical and laboratory characteristics, initial staging, and outcomes of aids patients with Kaposi's sarcoma at an university hospital of Recife, Pernambuco.

Methods:: This is a descriptive study with analytic character, retrospective, of a case series between 2004 and 2014.

Cutaneous ectopic schistosomiasis: diagnostic challenge.

Cutaneous schistosomiasis is a rare clinical manifestation of schistosomiasis, an infectious and parasitic disease, caused in Brazil by the trematode Schistosoma mansoni. The lesions are due to the deposition of eggs or, rarely, adult worms, usually involving the genital and groin areas. Extra-genital lesions occur mainly on the torso as papules of zosteriform appearance.

Cutaneous tuberculosis: diagnosis, histopathology and treatment - part II.

The evolution in the knowledge of tuberculosis' physiopathology allowed not only a better understanding of the immunological factors involved in the disease process, but also the development of new laboratory tests, as well as the establishment of a histological classification that reflects the host's ability to contain the infectious agent. At the same time, the increasing bacilli resistance led to alterations in the basic tuberculosis treatment scheme in 2009. This article critically examines laboratory and histological investigations, treatment regimens for tuberculosis and possible adverse reactions to the most frequently used drugs.

Cutaneous tuberculosis: epidemiologic, etiopathogenic and clinical aspects - part I.

Cutaneous tuberculosis (CTB) is the result of a chronic infection by Mycobacterium tuberculosis, M. ovis and occasionally by the Calmette-Guerin bacillus. The clinical manifestations are variable and depend on the interaction of several factors including the site of infection and the host's immunity.

Antimicrobial resistance profile of Staphylococcus aureus isolates obtained from skin and soft tissue infections of outpatients from a university hospital in Recife -PE, Brazil.

Background: Staphylococcus aureus has a notable ability to acquire resistance to antibiotics, and methicillin resistance represents a growing public health problem. Methicillin-resistant S. aureus (MRSA) has also become important outside the hospital environment, particularly in the United States.

Evaluation of clinical adverse effects and laboratory alterations in patients with acne vulgaris treated with oral isotretinoin.

Background: Oral isotretinoin therapy has completely changed the treatment of acne. The clinical adverse effects of isotretinoin are classified into two groups: mucocutaneous and systemic toxic. Laboratory alterations such as dyslipidemia and increase of hepatic enzymes are reported.

[Splenic tuberculosis during psoriasis treatment with infliximab].

Psoriasis is a chronic inflammatory disease affecting the skin and occasionally the joints. The biological agents have been engineered to target a specific step in the inflammatory cascade that leads to psoriasis, including tumor necrosis factor, which has a central role in the host defense against Mycobacterium tuberculosis. This is a case report about a psoriatic patient who presented splenic tuberculosis during treatment with infliximab.
