Most common oral alterations in the elderly--a review.

The population of Brazil is experiencing a fast and progressive aging process. Oral mucosa, which has a function as a barrier, is compromised by the aging process, allowing the action of predisposing agents. The older the population, the greater is the prevalence of lesions in oral mucosa. The causes may be neoplastic, infectious, bone pathologies, oral manifestations of systemic diseases, nutritional deficiencies, dental prostheses, medicaments, and bullous diseases, among others. Examination of the oral cavity should be carried out as an annual routine, and as a preventive measure for the entire elderly population, in order to reduce the morbidity and mortality from these diseases.

Physiologic alterations of oral mucosa due to aging: a review.

The Brazilian population, despite Brazil being considered a "country of young people", is undergoing an aging process entailed by a decline in the fertility and mortality rates. In the year 2000, seniors accounted for about 5.85% of the Brazilian, and population projections for 2025 estimate that the group will reach 14% by that time. Oral mucosa has a function of providing a barrier and promoting immune and inflammatory responses, thus protecting the body. During the aging process, those functions deteriorate, allowing the action of predisposing agents. There is thus the need of better knowledge of the conditions of oral health in the Brazilian population, allowing for adoption of preventive measures. Oral cavity examination should be routinely performed in the elderly on a yearly basis, as a preventive measure which would reduce the morbidity and mortality in this population.

Cardio-facio-cutaneous syndrome: a case report.

Cardio-facio-cutaneous syndrome is a genetic disorder with a characteristic facies, abnormal skin and hair, mental retardation and congenital heart disease. It may be confused with Noonan's syndrome, which has a familial pattern and does not present hyperkeratotic skin lesions and abnormal hair, and there are few cases reported in the literature. We describe the first case of typical cardio-facio-cutaneous syndrome observed in Brazil.

Alpha-hydroxy acids: unapproved uses or indications.

Alpha-hydroxy acids have been used for rejuvenation since ancient times, and now there are several on the market. Depending on the concentration, some have been shown to be effective as peeling agents and for rejuvenation. Glycolic acid and lactic acid are the alpha-hydroxy acids most frequently used in cosmetics, although there are many others used in combination. Some of the most striking advances in dermatology have followed the off-label use of drugs, which is widespread and unavoidable, but a well founded scientific approach to an individual patient's pathology must be emphasized as the number of products, regimens, and adjuncts increases exponentially in the cosmetic field. In this article the authors review some unapproved uses of alpha-hydroxy acids. More published data on the scientific value of these off-label indications that proves whether they are effective or not is needed.
