Polymorphous adenocarcinoma of the salivary glands : reappraisal and update

Although relatively rare, polymorphous adenocarcinoma (PAC) is likely the second most common malignancy of the minor salivary glands (MiSG). The diagnosis is mainly based on an incisional biopsy. The optimal treatment comprises wide surgical excision, often with adjuvant radiotherapy. In general, PAC has a good prognosis. Previously, PAC was referred to as polymorphous low-grade adenocarcinoma (PLGA), but the new WHO classification of salivary gland tumours has also included under the PAC subheading, the so-called cribriform adenocarcinoma of minor salivary glands (CAMSG). This approach raised controversy, predominantly because of possible differences in clinical behaviour. For example, PLGA (PAC, classical variant) only rarely metastasizes, whereas CAMSG often shows metastases to the neck lymph nodes. Given the controversy, this review reappraises the definition, epidemiology, clinical presentation, diagnostic work-up, genetics, treatment modalities, and prognosis of PAC of the salivary glands with a particular focus on contrasting differences with CAMSG.Peer reviewe

The effect of tetraploidization of wild Arachis on leaf morphology and other drought-related traits

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Cultivated peanut is an allotetraploid (genome type AABB) with a very narrow genetic base, therefore wild species are an attractive source of new variability and traits. Because most wild species are diploid, the first step of introgression usually involves hybridization of wild species and polyploidization to produce a synthetic allotetraploid (AABB) that is sexually compatible with peanut. This study investigates drought-related traits such as leaf morphology, transpiration profile, chlorophyll meter readings (SCMR), specific leaf area (SLA) and transpiration rate per leaf area for two wild diploids (Arachis duranensis and Arachis ipaensis) that could be of interest for improvement of the peanut crop. Furthermore, the inheritance of the traits from the diploid to the tetraploid state was investigated. Results showed that whilst some diploid traits such as SCMR, are maintained through hybridization and polyploidization, most characters, such as the leaf area, stomata size, trichome density and transpiration profile, are substantially modified. The study concludes that direct evaluations of drought-related traits in wild diploids may be useful for evaluation of wild species to be used in introgression. However, evaluations on wild-derived synthetic tetraploids are likely to be more informative.

Assistência de Enfermagem no período de recuperação anestésica: revisão de literatura La asistencia de enfermería en el período de recuperación anestésica: revisión de literatura Recovery room: a review of nursing care literature

Após constatação de que os pacientes submetidos aos mais diversos procedimentos cirúrgicos, ao serem admitidos na unidade de recuperação anestésica, apresentavam seus prontuários com dados relevantes mal registrados, de forma desorganizada e incompletos, foi realizado um levantamento bibliográfico nacional no período 1990 à 2002 para identificar e analisar como a assistência de enfermagem em sala de recuperação anestésica é documentada. Utilizou-se o sistema informatizado de busca LILACS (Literatura Latino Americana de Ciências da Saúde), PERIENF (Acervo de Periódicos da Escola de Enfermagem da Universidade de São Paulo) e BDENF (Biblioteca J. Baeta Viana da Universidade Federal de Minas Gerais). Os indexadores foram: assistência de enfermagem, recuperação anestésica e período pós-operatório imediato. Encontrou-se 16 artigos referentes a este tema, apesar da importância dada a continuidade do cuidado ao paciente neste período.<br>Después de constatarse que los pacientes sometidos a los más diversos procedimientos quirúrgicos, al ser admitidos en la unidad de recuperación anestésica, tenían historias clínicas con los datos relevantes mal registrados, de forma desorganizada y incompletos, fue que se realizó una revisión bibliográfica nacional en el período de 1990 al 2002 para identificar y analizar cómo es documentada la asistencia de enfermería en sala de recuperación anestésica.

The goal of the present study is to analyze bibliographic data from 1990 to 2002 on recovery room nursing care. The data was obtained from LILACS (Latin America Literature about Health Science), PERIENF (Nursing School Library of the University of São Paulo) and BDENF (Library of Federal University of Minas Gerais). The key words were nursing care, recovery room and immediate post-operative period. Only 16 articles were found, indicating a shortage of literature on this topic. The recovery room period is an important period of hospitalization and the data are essential for continuous care
