Clinical practice guidelines in Brazil - developing a national programme.

In Brazil, governmental and non-governmental organisations develop practice guidelines (PGs) in order to optimise patient care. Although important improvements have been made over the past years, many of these documents still lack transparency and methodological rigour. In order to conduct a critical analysis and define future steps in PG development in Brazil, we carried out a structured assessment of strengths, weaknesses, opportunities and threats (SWOT analysis) for the development of a national guideline programme.

Influence of coffee and red wine on tooth color during and after bleaching.

Objective: The aim of this study was to evaluate the influence of coffee and red wine staining on tooth color during and after bleaching.

Materials And Methods: Blocks obtained from human molars were divided into 11 groups (n = 5) in accordance with the bleaching treatment-peroxide carbamide 10%, 15% or 20%-and in accordance with the stain therapy-coffee, wine or without staining (control). Color change analysis was performed by photo-reflectance using a spectrophotometer, during (3-times/week) and after (7, 15 and 30 days) the bleaching treatment.

Oral manifestations as first clinical sign of acute myeloid leukemia: report of a case.

Leukemia is the most common malignancy in children younger than 15 years old. Acute myeloid leukemia frequently presents with early oral manifestations. The purpose of this study was to report the case of a 6-year-old male patient who showed persistent and severe hemorrhage after a tooth extraction and generalized gingival enlargement over a short period of time.

Nosocomial bacteremia in neonates related to poor standards of care.

Background: In developing countries, intravenous liquids are mixed and administered by nurses, sometimes under suboptimal infection control conditions. We hypothesized that outbreaks of infusate-associated neonatal bacteremias are common, and we evaluated whether they can be detected by vigilant microbiologic surveillance of infusates.

Methods: We studied intravenous infusates administered to neonates in a Mexican hospital where mixtures of infusates were prepared in hospital wards.
