ABSTRACT
BACKGROUND: The diagnosis of Alzheimer's disease (AD) can bring financial and emotional consequences to patients and caregivers. Whether or not the diagnosis should be disclosed to patients is a matter of debate amongst physicians and can be influenced by culture and experience. OBJECTIVE: To investigate the current practice of physicians who attend and treat patients with dementia in Brazil regarding the disclosure of dementia diagnosis and compare the practice with what has been performed 15 years ago in the country. METHODS: Data were evaluated using an electronic questionnaire. The questions used to carry out this research were similar to the questions of the study carried out 15 years ago 9. The form was sent to the Brazilian Academy of Neurology, the Brazilian Association of Geriatrics and Gerontology, and the Brazilian Association of Psychiatry, which forwarded it to their members. Analyses were conducted through non-parametric statistical tests, with a post-hoc assessment. RESULTS: 397 physicians responded to the survey, of which 231 are neurologists, 124 geriatricians, 29 psychiatrists and 13 from other specialties. The mean age was 45.2 years. The majority (66.7%) of the physicians reveal the diagnosis of AD always or usually. The youngest group of neurologists were more likely to disclose the diagnosis than the oldest group with a significant difference between them. In comparison to the 2008 Brazilian study, the percentage of physicians who always or usually disclose the diagnosis has risen by 22%. On the other hand, 12.3% of the physicians rarely or never disclose the diagnosis, in comparison to 25,3% in 2008. The main reasons for not disclosing the diagnosis concern the patients' mental health. CONCLUSION: Advances in dementia knowledge and biomarkers availability probably explain the increase in the rate of disclosure. The main challenge is to reconcile the autonomy of affected individuals, mental health issues after the diagnosis and the family member's opinion.

RESULTADOS: 397 médicos responderam à pesquisa, sendo 231 neurologistas, 124 geriatras, 29 psiquiatras e 13 de outras especialidades. A média de idade foi de 45,2 anos (standard deviation-SD = 11.6 years). A maioria (66,7%) dos médicos revela o diagnóstico de DA sempre ou habitualmente. O grupo mais jovem de neurologistas foi mais propenso a revelar o diagnóstico do que o mais velho, com diferença significativa entre eles. Em comparação com o estudo brasileiro de 2008, o percentual de médicos que sempre ou usualmente revelam o diagnóstico aumentou em 22%. Em contrapartida, 12,3% dos médicos raramente ou nunca o divulgam, em comparação a 25,3% em 2008. Os principais motivos para não o revelar dizem respeito à saúde mental dos pacientes. CONCLUSãO:: Avanços no conhecimento da demência e disponibilidade de biomarcadores provavelmente explicam o aumento na taxa de divulgação. O principal desafio é conciliar a autonomia dos indivíduos afetados, problemas de saúde mental após o diagnóstico e opinião do familiar.

Fluorescein (FS) was first used to visualize malignant brain tumors in 1948. FS accumulates in malignant gliomas where the blood-brain barrier is disrupted and provides intraoperative visualization that is similar to preoperative contrast-enhanced T1 images in which gadolinium accumulation is seen.1 FS can be viewed under white light, but the use of an operating microscope fitted with a dedicated filter (YELLOW 560 nm Filter, Carl Zeiss Meditec, Oberkochen, Germany) allows us to significantly reduce the dose needed to highlight tumoral tissue.1,2 FS is excited at 460-500 nm and emits a green, fluorescent emission wavelength at 540-690 nm.2 It is virtually free of side effects and has low costs3 (approximately 6.9 USD each vial: Brazil). Video 1 presents a case of a 63-year-old man who underwent a left temporal craniotomy to remove a temporal polar tumor. The FS is administered at the time of anesthesia before a craniotomy. The tumor was then removed with standard microneurosurgical technique by the alternating use of white light and YELLOW 560 nm filter illumination. The use of FS was found "helpful" to discriminate the brain tissue and tumor tissue (bright yellow). Fluorescein-guided technique with a dedicated filter on the surgical microscope is safe and allows complete resection of high-grade gliomas.
