Hearing problems in Mexican American elderly.

OBJECTIVE: To investigate hearing problems in a sample of elderly Mexican Americans. STUDY DESIGN: A longitudinal field study of a cohort of 3,050 subjects with in-person baseline and a 2-year follow-up. Population-based, cross-sectional, weighted data were analyzed. SETTINGS AND SUBJECTS: Hispanic Established Populations for Epidemiologic Studies of the Elderly (H-EPESE) consisting of Mexican Americans aged 65 and older provided basic health data using area probability sampling in five southwestern states during 1993 and 1994. MAIN OUTCOME MEASURES: Information was collected regarding demographics, medical conditions, smoking, and alcohol consumption. Hearing problems were identified through a series of self-perceived hearing problem questions, hearing aid use, and inability to hear a normal voice. RESULTS: A hearing problem was identified in 24.5% of this cohort (weighted, 748/3,049). Statistical analysis using a multiple logistic regression model was performed to identify factors jointly associated with hearing problems. Age group (odds ratio [OR] = 2.7, p<0.0001), male sex (OR = 1.9, p< 0.0001), hypertension (OR = 1.4, p<0.001), arthritis (OR = 1.5, p<0.0005), significant depressive symptomatology (OR = 1.4, p<0.002), and ever having consumed alcohol (OR = 1.4, p<0.005) were jointly statistically significantly associated with hearing problems. Number of cigarettes smoked daily (e.g., 0, 1-10, 11-20, etc.) was nearly significantly associated with a hearing problem in the multivariate model (OR = 1.1 for each increased in category, p<0.07). CONCLUSIONS: Hearing problems are common in this population. Control of hypertension, an amelioration of arthritis, and decreasing the consumption of alcohol and cigarettes may lower the likelihood of development of a hearing problem. Initial depressive symptomatology may have occurred subsequent to the hearing loss. A longitudinal study would allow determination of the direction of causation.

Urachal carcinoma: a report of two cases.

Urachal carcinoma is a rare neoplasm of the urinary bladder. We present two cases. Case 1, a male patient, noted urinary frequency and micturition pain for two months. The surgical specimen from a partial cystectomy represented a transitional cell carcinoma that developed from a urachal diverticulum. Case 2, a female patient, had a long history of infraumbilical mass without umbilical discharge or urinary symptom. Pathologically, the mass showed a papillary adenocarcinoma arising from a urachal cyst. Both patients received successive en bloc operation. Local recurrence and peritoneal carcinomatosis occurred. Both expired 19 and 13 months respectively, after initial diagnosis.
