Resumen Objetivo: En la medida que la población va envejeciendo, la presencia de enfermedades crónicas, dolores y discapacidades va aumentando; estas afecciones cuentan con un bajo pronóstico de cura, lo cual lleva a complicaciones en el desempeño de las actividades de la vida diaria, dificul tando la independencia y la autonomía de quien las padece. Actualmente más de 868 millones de personas superan los 60 años. Se habla de casi un 12 % del total de la población mundial, y para el año 2050, se estima que haya un incremento del 21 %, equiparando el porcentaje de los menores de 15 años. Esta proyección supone nuevos retos sociales y una respuesta del sistema de salud, que permita favorecer entre los envejecidos, procesos de adaptabilidad y crecimiento psi cosocial. Objetivo: Identificar la asociación existente entre la dependencia funcional entendida como aquella condición de imposibilidad por deterioro físico y cognitivo, que tiene el sujeto para valerse por sus propios medios y el dolor al cual hace referencia, aquella experiencia senso rial y emocional desagradable causada por injuria real o potencial a un tejido. Método: Para el presente artículo se efectuó una búsqueda bibliográfica en bases de datos como Redalyc, Google académico, Ebsco, Medline, entre otras, donde fueron seleccionados 60 artículos que estuviesen incluidos en revistas indexadas. Resultados: Se encuentra una gran prevalencia de estudios que reportan que el envejecimiento asociado al dolor evidencia mayor nivel de dependencia funcional en el adulto mayor.

Abstract Objective: The presence of chronic diseases and increased pain and disability suggest a poor prog nosis for rehabilitation. This prognosis tends to generate complications in performing routine activities; and restraint in individual independence and autonomy is evident in most of the cases as the population ages. Currently more than 868 million people are over 60 years and they make up almost 12 % of the total world population. By 2050, it is estimated that there will be a 21 % increase in relation to the percentage of children under 15. This data implies that new social chal lenges and health care system response subserve elderly processes of adaptability and psychosocial growth in order to generate a range of resources for the elderly to cope health problems which affect their quality of life. To identify the association between functional dependence understood as the condition of physical impossibility and cognitive impairment elderly people have in carry ing out everyday tasks and pain related to "sensory experience and unpleasant emotional injury caused by real or potential tissue. Methodology: The literature review submitted in this paper was retrieved from databases such as Redalyc, Google Scholar, Ebsco, Medline Databases, etc., and 60 items included in indexed journals were selected. Results: As a result, a high prevalence of studies reporting that aging was associated with a higher level of functional dependency in the elderly.

This paper describes the effects of a strong type of vaccine - Moulthrop G603 º and an intermediate-plus type of vaccine - 228E º in meat-type chickens challenged with a very virulent strain of infectious bursal disease virus (vvIBDV). Blood samples and bursa of Fabricius were taken weekly up to 42 days of age. It was concluded that bursa of Fabricius weight, bursa weight:body weight ratio, body weight and antibody titer evaluated before and after challenge with vvIBDV were not enough to consistently and conclusively differentiate or estimate the protection given by vaccination. Quantitative evaluation of injury intensity and the number of altered lymphoid follicles revealed that Moulthrop G603 caused moderate microscopic lesions in one out of seven birds vaccinated at 14 days of age, while 228E vaccine did not induce IBD-typical microscopic lesions in the bursa of Fabricius. Good protection against bursal microscopic lesions was obtained when a strong type of vaccine was used before challenging with vvIBDV. It was concluded that quantitative evaluation of microscopic lesions might be useful to measure the injury induced by vaccinal IBDV, as well as the level of protection and/or immunosuppression induced by IBDV challenge in vaccinated and non-vaccinated chickens.

O cisto nasolabial é um raro cisto da linha média facial. Sua ocorrência bilateral é extremamente incomum. Poucos casos são descritos na literatura. A manifestação clínica representa o mais importante critério de diagnóstico. A terapia consiste em remoção cirúrgica intraoral. Neste artigo, os autores apresentam dois casos de cisto nasolabial bilateral, ambos em pacientes de meia idade do sexo feminino, e uma revisão da literatura sobre o tema.

The nasolabial cyst is an uncommon midfacial lesion. Its bilateral occurrence is extremely rare. Few cases ara described in the literature. This clinical manifestation represents the most important criterion for diagnosis. Therapy consists of surgical removal using an intraoral approach. The authors present two cases of bilateral nasolabial cysts, both in middle aged females, and a review of the literature is included.
