COVID-19, pandemia y acúfeno / COVID-19, pandemic and tinnitus

El acúfeno es un síntoma que puede presentarse aislado o en diferentes patologías. Se describe como la percepción de un sonido o percepción auditiva fantasma no producida por una vibración o estímulo acústico externo, que es inaudible para el entorno. La COVID-19 causada por el virus SARS-CoV-2, es una enfermedad que ha mostrado diversidad en su expresión, severidad, síntomas y secuelas. El acúfeno es una condición relacionada con el sistema auditivo que ha sido estudiada durante la pandemia por COVID-19 y se ha podido observar un incremento en la incidencia y/o exacerbación de la percepción de este síntoma, en donde se involucran múltiples factores que se vuelven importantes de considerar.

It is described as the perception of a sound, or as a phantom auditory perception that is not produced by a vibration or external acoustic stimulus, which is inaudible to the environment. COVID-19 caused by the SARS-CoV-2 virus, is a disease that has shown diversity in its expression, severity, symptoms and sequelae. Tinnitus is a condition related to the auditory system that has been studied during the COVID-19 pandemic, and an increase in the incidence and/or exacerbation of the perception of this symptom has been observed, involving multiple factors that become important to consider.

Risk and protective factors associated with youth violence among secondary school students in a nationally representative sample in Puerto Rico

During the past decade, youth violence has received increasing attention as a major public health issue in Puerto Rico as well as in the United States. This study sought to identify risk and protective factors of youth violence in a representative sample of school adolescents in Puerto Rico. Risk and protective factors were grouped into five domains: individual, family, peer group, school and community. From a total of 2,385 participants, 10.7 reported at least one violent behavior and 3.4 reported two or more violent behaviors. In multiple regression analysis the risk factors identified were male gender, junior grade students, having a favorable attitude towards antisocial behavior, use of ecstasy, involvement with antisocial peers and reporting antisocial parents. Participation in family decisions was the only protective factor associated with violence. Findings from this study could have important implications for the development of preventive programs for the adolescent population in Puerto Rico

Midriasis farmacológica en conejos inducida por antagonistas de histamina / Pharmacologic midriasis induced by histamine antagonist in rabits

El propósito de este trabajo es determinar el efecto de antagonistas de histamina sobre el esfínter pupilar y la superficie ocular en conejos pigmentados. Para ello se realizó un estudio experimental, longitudinal y comparativo. Se estudiaron 50 ojos de 25 conejos, divididos en 4 grupos: I cimetidina, II clorfenamina, III tropicamida al 1 por ciento y IV fenilefrina al 10 por ciento + ciclopentolato al 1 por ciento. Como resultado, se demostró que la combinación de cimetidina y tropicamida al 1 por ciento produce pérdida de reflejo pupilar a los 5 minutos, midriasisi máxima a los 15 minutos, delcinando a los 45 minutos de su aplicacion. Se concluye que la combinación de cimetidina y tropicamida al 1 por ciento en forma tópica, induce pérdida del reflejo pupilar y midriasis a corto plazo desapareciendo rápidamente el afecto

Profile of a population using a primary health care center in Puerto Rico

PURPOSE: To describe the services delivered by the Family Medicine Physicians at a Community Health Center. METHODS: All information from patient visits during the natural year 1996 were registered using a commercialized computer program. The information was gathered by different means: initial interview, physician's report, records, and personal interviews. RESULTS: A total of 13,203 visits were registered; this represent a total of 4,493 patients. Most of the patients were women, and with a mean age of 38. As expected, most of the patients have Medicaid. The most common conditions seen were hypertension, diabetes, and respiratory diseases. The mean number of visits during the year for almost all conditions was three. Most of the children and adolescents visit the Center due to respiratory conditions, while adults come due to hypertension, diabetes, and musculoskeletal conditions
