Pyodermitis are primary skin infections mainly caused by pyogenic bacteria of the Staphylococcus and Streptococcus genera. They are relatively common diseases that affect adults and children. There have been frequent reports of bacterial resistance to the recommended antibiotics over the last few years; however, new substances are in use or under development, and this represents an evolution in the treatment of pyodermitis. This review aims at describing clinical, diagnostic and therapeutical features of major pyodermitis: impetigo, ecthyma, erysipelas, staphylococcal scalded skin syndrome and folliculitis.

Introduction: Brazilian epidemiological studies on systemic lupus erythematosus (SLE) are scarce, and currently available data originate almost entirely from international literature. Objectives: To determine the incidence and some clinical and laboratory characteristics of patients with SLE in the municipality of Cascavel, state of Paraná, Brazil. Patients and Methods: Data were collected from August 2007 to July 2008 in all health services of Cascavel providing health care in rheumatology: a university-affi liated hospital, a public outpatient clinic, and three private clinics. Results: The study identifi ed 14 patients diagnosed with SLE, which resulted in an estimated incidence of 4.8 cases/100,000 inhabitants/ year. All patients were female, and the mean age was 41.5 years. The highest incidence of disease occurred between 30 and 39 years of age, and 92.8% of patients met at least four of the 11 American College of Rheumatology (ACR) criteria for diagnosis of SLE. The drug treatment of patients was also assessed and proved to be in accordance with the Brazilian Consensus for Treatment of SLE. Conclusion: The incidence obtained in the municipality of Cascavel is close to those reported in international studies.
