-Context -Esophageal candidiasis is often observed in patients with risk factors for its development and fluconazole is the therapeutic choice for the treatment of this disease. Objectives -To determine its frequency, by performing upper digestive endoscopy; to determine Candida species involved in its pathogenesis and verify their distribution according with the predisposing factors and to determine susceptibility to fluconazole in the samples. Methods -From March 2006 to April 2007, all patients submitted to esophagogastroduodenoscopy at the Digestive Endoscopy Unit in the Oswaldo Cruz University Hospital, Recife, PE, Brazil, were eligible for the study. Samples were collected from patients who presented lesions consistent with esophageal candidiasis in order to identify Candida species and verify their susceptibility to fluconazole. The predisposing factors for the occurrence of esophageal candidiasis were described. Results -Of 2,672 patients referred to upper endoscopy at the Digestive Endoscopy Unit, 40 (1.5%) had endoscopic findings compatible with esophageal candidiasis. The average age was 49.1 years. Twenty one patients (52.5%) were less than 50 years old, of which 82.6% were infected with HIV. Most of them (52.5%) were males and 65.0% were inpatients. Diseases were identified in 90% of the patients and 21 (52.5%) were HIV positive. Concerning endoscopic findings, severe forms of esophagitis were found in 50% of the patients with CD4 count <200. Non-albicans Candida species were isolated in 22.7% of HIV positive and in 45% HIV negative patients. A total of 6 (14.28%) samples were resistant to fluconazole, while 2 (4.76%) samples had dose depending susceptibility to this drug. Conclusions -Esophageal candidiasis prevalence was low, although within the results described by other authors. Male and inpatients were the most affected. The species isolated varied according to the characteristics of each group studied. Both, resistance and dose-depending susceptibility to fluconazole were considered high.

Onychomycosis in HIV/AIDS patients presents various clinical manifestations and may be caused by emerging fungi. The peculiarities presented by different fungal agents justify the need for identification to species level, with the purpose of guiding better therapeutic approaches and minimizing these patients' exposure to conditions presenting a risk of disseminated infection.

The aim of this study is to understand the role of nurses in the early diagnosis of breast cancer, to describe the actions and strategies used for this purpose and to know their perceptions about their role in this situation in a Basic Health Unit in the Municipality of Juazeiro-BA. This is a qualitative research of descriptive characteristics, with all nurses in zone IV of the city of Juazeiro-BA. After data collection, the data were grouped and analyzed using the Bardin method. The results showed that the professionals present knowledge about breast cancer and its screening, however, still deficient and confusing. There is a need for public policies that prioritize the training of professionals so that it can reflect on the improvement of health indicators.
