Controlled Substance Agreements and Other Best Opioid Prescription Practices.

Controlled substance agreements between providers and patients represent important strategies for setting expectations for chronic opioid therapy. These agreements generally summarize best opioid prescription practices and destigmatize practice policies such as regular toxicology screenings. These controlled substance agreements also set expectations for discontinuation of therapy if appropriate.

Subsequent breast and high grade serous carcinomas after risk-reducing salpingo-oophorectomy in BRCA mutation carriers and patients with history of breast cancer.

Risk-reducing salpingo-oophorectomy (RRSO) is a procedure to reduce the risk of adnexal cancer in BRCA mutation carriers and for hormonal manipulation in women with breast cancer (BC). The goal of the study is to report the frequency of subsequent BC and high-grade serous carcinoma (HGSC) following RRSO in BRCA1 and BRCA2 mutation carriers and in patients with personal history of BC with or without BRCA mutation. A series of 147 consecutive patients who received a RRSO were reviewed. Patient's age, clinical history, BC histotype, gene mutation data, incidence of post-RRSO BC and HGSC and time intervals were analyzed. The cases were followed for a mean of 49 months. Group 1 consists of 97 cases with pathogenic or likely pathogenic "deleterious" mutation BRCA1 (n = 49) or BRCA2 (n = 48). Group 2 consists of 50 cases with history of BC and no documented BRCA gene mutation. Prior to RRSO, 42 (43%) cases in group 1 had a history of BC and all cases in group 2 had a history of BC. There was no difference between the groups in the age at diagnosis for BC (Mean of 44 years). Following RRSO, 2/49 cases (4%) with BRCA1 mutation were found to have occult HGSC and none in BRCA2 cases. There were also 1 BC recurrence and 1 primary BC with BRCA1 mutation compared to 5 recurrent BC in Group 2 (10%). In conclusion, the risk of subsequent recurrent BC after RRSO appears to be higher (10%) in patients with history of BC with no BRCA mutation when compared to (2%) in BRCA mutation carriers.

Correlation between invasive mammary carcinoma grade and size in ultrasound-guided core needle biopsy and subsequent surgical excision.

The purpose of this study was to correlate the histologic grade, mitotic rate and size of invasive mammary carcinomas (IMC) on ultrasound (US) core needle biopsy (CNB) and the follow-up excision (FUE). The underestimation and overestimation of the grades by CNB were 11% and 8%. CNBs were more specific for grade 3 tumors. Tumors >10 mm by US examination showed greater concordance in grades. The size in the FUE was the best determinant of pT followed by US examination. The extent of IMC on CNB was larger than FUE in 8% resulting in pT upstaging in 3% of cases.

Urine toxicology screening in an urban stroke and TIA population.

OBJECTIVE: We sought to determine the rate of urine toxicology screening, differences in testing, and outcomes among patients with stroke and TIA presenting to a tertiary care emergency department. METHODS: In this retrospective cohort study, patients admitted with stroke or TIA to a single tertiary care stroke center between June 2005 and January 2007 were identified through a stroke database. Factors that predicted urine toxicology screening of patients and a positive test, and discharge outcomes of patients based on toxicology result were analyzed. Stroke severity, treatment with tissue plasminogen activator, discharge status, and stroke etiology were compared between toxicology positive and negative patients. RESULTS: A total of 1,024 patients were identified: 704 with ischemic stroke, 133 with intracerebral hemorrhage, and 205 with TIA. Urine toxicology screening was performed in 420 patients (40%); 11% of these studies were positive for cocaine (19% younger than 50 years and 9% 50 years or older). Factors that significantly predicted the performance of a urine toxicology screen were younger age (<50 years) and black race (<0.001). Positive toxicology screens occurred in a broad range of patients. There were no significant differences in admission NIH Stroke Scale score, stroke etiology, and discharge status between toxicology-positive and -negative patients. CONCLUSIONS: In this study, patients with stroke and TIA who were young and black were more likely to have urine toxicology screening. Eleven percent of all tested patients (and 9% of patients 50 years or older) were positive for cocaine. To avoid disparities, we suggest that all stroke and TIA patients be tested.
