Alcohol y salud: ¿Alcohol y salud?: revisión bibliográfica / Alcohol and health: alcohol and health?: review of the literature

El consumo excesivo de bebidas alcohólicas constituye un serio problema sanitario y social. En los últimos años se han destacado sus propiedades anticancerosas, antioxidantes y protectoras contra la enfermedad cardíaca coronaria, lo que ha generado controversias entre beneficios y perjuicios de su consumo. Los efectos tóxicos sobre el sistema nervioso central lideran el cuadro de la intoxicación aguda, mientras que los efectos del consumo crónico afectan prácticamente todo el organismo, alterando numerosas funciones aún en etapas tempranas de la vida. Los profesionales de las ciencias de la salud tienen un rol clave en la prevención de los daños producidos por este hábito tan difundido.

Effect of two mouthwashes on salivary pH

Etários de adultos voluntarios sanos, para analizar el efecto de dos colutorios sobre el pH salival y relacionarlo con la edad la capacidad buffer y el flujo salival. Se utilizaron dos marcascomerciales de colutorios (MW), ListerineCoolMint® (MWa) y eriobacter® (MWb). Primero se caracterizó la saliva sin estimular de cada individuo, se le midió el volumen minuto, el pH y la capacidad buffer. El pH salival se evaluó antes del buche con cada MW, inmediatamente después del enjuague bucal, 5 minutos después y luego cada 10 minutos (a los 15,25, 35 min) hasta que el pH inicial se recuperó. Para el análisis estadístico de los datos se utilizaron: ANOVA en bloque,test t apareado y el test de correlación de Pearson. Al caracterizar la saliva, se obtuvieron los siguientes valores promedio: 0.63 mL/min, 7.06 y 0.87 de volumen minuto,pH, y capacidadbuffer. Luego del enjuague se observó un incremento inmediato y significativo del pH salival alcanzando valores de 7.24 (MWb) y 7.30 (MWa) para descender a un valor estable luegode 15 minutos. El importante incremento del pH salival luego del uso del colutorio, muestra que la saliva es un sistema dinámico y que el organismo es capaz de responder a estímulos con cambios en su composición. Se hace evidente que el pH del agente externo, no es un buen indicador de su potencialerosivo sobre los elementos dentarios ya que los sistemas biológicos tienden a neutralizarlo. Los presentes resultadosponen de manifiesto la importancia de las mediciones en vivo y refuerzan el concepto de la función protectora de la saliva...

Mouthrinses containing alcohol and oral cancer: revision of epidemiological studies / Colutorios que contienen alcohol y cáncer bucal: revisión de estudios epidemiológicos

The strong association between alcohol usage and the development of oral cancer (OC) has been reported in numerous papers. As some mouthrinses contain significant amounts of ethanol, a possible relationship to this pathology has been considered. The purpose of the present paper is to analyze several epidemiological studies which evaluated the association between commercial mouthrinses and the etiology of OC. Although some authors report an association, most of the studies are unclear and sometimes contradictory. The controversial aspects regarding the role of alcohol in OC may also make difficult to find a clear relationship between the use of mouthrinses containing alcohol and OC.

Existen numerosas publicaciones que informan una fuerte asociación entre el consumo de alcohol y el desarrollo del cáncer oral (CO). Debido a que algunos colutorios contienen cantidades significativas de etanol se ha considerado una posible relación entre su uso y esta patología. El propósito del presente trabajo es analizar algunos estudios epidemiológicos en los cuales se evaluó la posibilidad de que los colutorios comerciales puedan estar involucrados en la etiología del CO. Aunque algunos autores informan asociación, la mayoría de los estudios son poco claros y algunas veces contradictorios. Los aspectos controversiales respecto al papel del alcohol en el CO, dificultan el hallazgo de una relación directa entre el uso de los colutorios que contienen alcohol y el CO.

Oral cancer mortality in the province of Cordoba, Argentine Republic in the period 1975-2000. A comparative study with other populations.

UNLABELLED: Malignant neoplasm (MN) mortality worldwide ranks among the first four causes of death, in the 1990 decade (1-4). The aim of this work is to study the eight most frequent MN mortality rates, and especially that one caused by oral cancer (OC) in the province of Cordoba, Argentine Republic, in the period between 1975 and 2000, in order to analyze its characteristics and compare with other populations in America and Europe. MATERIAL AND METHODS: The data were provided by the provincial and national Health Ministry and Globocan 2000. RESULTS: The highest male rates were those of Slovakia and France, prevailing lung and bronchus tumors; whereas in females the highest rate was that of breast cancer in the United Kingdom and Germany, and lung cancer in the United States. Regarding to OC in the populations under study, Slovakia and France held the highest rates for both sexes, being Cordoba and Argentina among the lowest values, especially in women. Tongue was the most frequent site in Cordoba (43.5%), followed by salivary glands (23.7%). Male prevailed over female and the oldest ages were observed in the period 1995-2000. The mortality rates by MN in all sites increased 6.6% in both sexes, and by OC 77% in women within the period under study in Cordoba. Oral cancer is a serious problem for public health causing great morbidity and mortality, a situation that has not improved in decades. Mortality rates are an important tool towards implementation and planning of health policies and programs for cancer prevention.

Necrotizing sialometaplasia: report of five cases.

Necrotizing sialometaplasia (NS) is a self-limiting inflammatory disease, that involves salivary glands, more frequently the minor ones. Although its etiopathogenesis remains still unknown some authors suggest that a physico-chemical or biological injury on the blood vessels may produce ischemic changes, leading to infarction of the gland and its further necrosis. Its clinical and histologic feature resemble malignancy. Clinically it may appear like an ulcer with slightly elevated irregular borders and necrotic base. Histologic features are squamous metaplasia of ducts and acini and a pseudoepitheliomatous hyperplasia of the overlying mucosa. These characteristics may induce to an inapropiated diagnosis of malignant neoplasia. A correct diagnosis to avoid mutilant surgical treatments is essential, considering that it is a self-limiting disease. In this report we describe five cases of NS in females, located in minor glands of the palate.

Antifungal topical therapy in oral chronic candidosis. A comparative study.

The aim of the present paper was to evaluate the effect of fenticonazole and to compare it with that of ketoconazole and nystatin in the topical treatment of oral chronic candidosis. Eighty patients diagnosed with erythematous chronic candidosis were divided into four groups, according to the cream they were provided with 3% fenticonazole, 2% fenticonazole, 100000UI nystatin, and 2% ketoconazole in orabase respectively. A clinical assessment was made at 7, 15, 30 and 45 days. Fifty-one of them finished the trial. ANOVA, Kruskall Wallis and Wilcoxon tests were applied for statistical analysis. There was a significative decrease of the oral lesions in all groups (p 0.0001). The remission grade was also analysed according to the localisation: lesions in the buccal mucosa and in the comissure all the patients achieved complete resolution, whereas tongue and palate lesions showed a significative decrease in all the treatments (p 0.00001). Fenticonazole proved to be as effective as nystatin and ketoconazole in topical treatment of oral candidosis.
