A percepção dos técnicos de anatomia patológica e médicos anatomo-patologistas quando à delegação do exame macroscópico aos técnicos de anatomia patológica

Dado o reduzido número de Médicos Anatomo-Patologistas (MAP) e o crescente interesse demonstrado pelos Técnicos de Anatomia Patológica (TAP) numa delegação de tarefas a nível do exame macroscópico, considerou-se pertinente realizar um estudo que abordasse a possibilidade de expandir as actividades profissionais dos TAP à realização do mesmo. Este estudo pretendeu averiguar qual a percepção dos dois grupos profissionais, no exercício, na região de Lisboa e Vale do Tejo, sobre o tema em causa. Este estudo exploratório sustentado no modelo de formação dos Pathologist's Assistants em vigor nos EUA, teve como variáveis as competências dos TAP na realização do exame macroscópico e a percepção dos TAP e dos MAP no respeitante a esta questão. O principal instrumento de recolha de dados foi um questionário, sujeito a análise estatística, aplicado em 13 hospitais da região acima referida (n=108 indivíduos). Cerca de 95% dos TAP e 75% dos MAP concordam com a existência de TAP com formação específica para a realização do exame macroscópico. A percepção de ambos os grupos profissionais relativamente à aquisição desta nova competência pelos TAP é bastante favorável. Contudo, a maioria (65,85% dos TAP e 94,44% dos MAP) defende que deveria haver restrição do tipo de amostras no exame macroscópico a realizar pelos TAP, devendo estas ser definidas pela necessidade de cada serviço. Conclui-se existir um evidente interesse de ambos os grupos profissionais na reestruturação da formação dos TAP que poderá viabilizar a realização do exame macroscópico por parte destes profissionais de saúde.

Versão portuguesa do Hearing Handicap Inventory for Adults: dados preliminares

Perda auditiva: elevada prevalência da perda auditiva (14,1%), efeitos na comunicação, efeitos em aspectos psicossociais, cognitivos, da fala e linguagem. Avaliação da perda auditiva: baseia-se nos testes audiométricos psicoacústicos, base audiometria tonal, que permite estimar a sensibilidade auditiva (normal vs anormal), permite classificar o tipo e grau de perda auditiva, avaliação qualitativa com a utilização de escalas desenvolvidas para esse efeito, HHIA (Hearing Handicap Inventory for Adults), instrumento desenvolvido a partir do HHIE (Hearing Handicap Inventory for the Elderly), para ser usado com pacientes de idade inferior a 65 anos.

Glucose-6-Phosphate dehydrogenase deficiency in children from 0 to 14 years hospitalized at the Pediatric Hospital David Bernardino, Luanda, Angola

The Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzymatic defect in the world. The most common clinical manifestations are acute hemolytic anemia associated with drugs, infections, neonatal jaundice and hemolytic non-spherocytic chronic anemia. The main aim of this study was to determine the frequency of major genetic variants of G6PD leading to enzyme deficiency in children from 0 to 14 years at a Pediatric Hospital in Luanda, Angola. A cross-sectional and descriptive analytical study covered a total of 194 children aged from 0 to 14 years, of both genders and hospitalized at the Pediatric Hospital David Bernardino, Luanda between November and December, 2011. The G202A, A376G and C563T mutations of the G6PD gene were determined by real-time PCR with Taqman probes. The disabled A-/A- genotype was detected in 10 girls (10.9%). Among the boys, 21 (20.6%) presented the genotype A-. Considering all the samples, the A- variant was observed in 22.4% of cases. The Mediterranean mutation was not detected in the Angolan sample. Furthermore, no association was found between genotype and anemia, nutritional state and mucosa color. A significant association, however, was observed with jaundice. Based on the results obtained, there is a clear need to identify those with the disabled genotype in the Angolan population in order to avoid cases of drug-induced anemia, particularly in the treatment of malaria, so prevalent in Angola.

Determination of airborne nanoparticles in elderly care centres

According to numerous studies, airborne nanoparticles have a potential to produce serious adverse human health effects when deposited into the respiratory tract. The most important parts of the lung are the alveolar regions with their enormous surface areas and potential to transfer nanoparticles into the blood stream. These effects may be potentiated in case of the elderly, since this population is more susceptible to air pollutants in general and more to nanoparticles than larger particles. The main goal of this investigation was to determine the exposure of institutionalized elders to nanoparticles using Nanoparticle Surface Area Monitor (NSAM) equipment to calculate the deposited surface area (DSA) of nanoparticles into elderly lungs. In total, 193 institutionalized individuals over 65 yr of age were examined in four elderly care centers (ECC). The occupancy daily pattern was achieved by applying a questionnaire, and it was concluded that these subjects spent most of their time indoors, including the bedroom and living room, the indoor microenvironments with higher prevalence of elderly occupancy. The deposited surface area ranged from 10 to 46 μm2/cm3. The living rooms presented significantly higher levels compared with bedrooms. Comparing PM10 concentrations with nanoparticles deposited surface area in elderly lungs, it is conceivable that living rooms presented the highest concentration of PM10 and were similar to the highest average DSA. The temporal distribution of DSA was also assessed. While data showed a quantitative fluctuation in values in bedrooms, high peaks were detected in living rooms.

Função visual e risco de quedas em idosos do concelho de Loures: um estudo exploratório

O processo de envelhecimento fisiológico é marcado por um decréscimo das capacidades motoras, redução da força, flexibilidade, função visual, entre outros. Adicionalmente, alterações patológicas do sistema visual com impacto na função visual podem alterar o equilíbrio e aumentar o risco de quedas. Os indivíduos com idade ≥ 50 anos representam entre 65% a 82% dos casos de baixa visão e cegueira. O risco de quedas é superior em mulheres com acuidade visual ≤0,5. Objectivo do estudo: avaliar a relação entre a função visual e o risco de quedas.
