To assess management of the disease, we studied patients treated between January 1, 2003 and December 31, 2007, in the Veterans Affairs-Tennessee Valley Healthcare System. Four hundred and fifty-four cases of senescent gynecomastia were retrieved from 670 charts addressing breast complaints (positive predictive value?=?68%). Average patient age was 68.5?years. Mean body mass index was 29.7. Ninety-two percent of patients were using multiple medications associated with gynecomastia. Medications were considered at least partially etiologic in 79.3% of cases. Medical conditions caused gynecomastia in 13.7%. Over 50% of patients underwent diagnostic imaging studies. One-fifth of patients were tested for etiologic endocrine tumors. Yield on this testing was 1.1% (1/93). Ninety-four percent of patients were managed nonoperatively. Case management in the Tennessee Valley Healthcare System was generally correct, selleck chemical Oxalosuccinic acid though there was excessive use of imaging, invasive diagnostic procedures, and endocrine assessment. Senescent gynecomastia, a benign disease, can usually be diagnosed by history and physical examination, requires little diagnostic testing, and should be treated nonoperatively. ""A third of breast cancers (BC) occur in women ��65?years (seniors). Anti-estrogen therapy (AET) significantly reduces BC recurrence and death. This study characterizes determinants of adherence to AET in seniors with BC. Provincial cancer registry and administrative claims data were accessed for all non-metastatic BC diagnosed in Quebec (1998�C2005) to identify seniors treated for 5?years with AET. Multivariate linear regression was used Ponatinib ic50 to assess the association with patient, disease, and physician characteristics and the 5-year medication possession ratio (MPR) for each patient. 4,715 women were included (mean age: 72.9). Mean MPR was 83.5%, 79% of patients reached a 5-year MPR of ��80%, and 34% discontinued AET at some point during treatment. The cumulative probability of discontinuation was 33.8% (mean time to discontinuation 2.3?years). The MPR decreased with increasing age and non-BC related hospitalizations, p?
