A Case Report of Uterine Torsion in a Postmenopausal Female with a Large Leiomyoma.

This case report discusses a diagnosis of uterine torsion in an 84-year-old woman who presented with five days of right lower quadrant abdominal pain, nausea, vomiting, constipation, and poor intake. Computed tomography (CT) imaging demonstrated a whorled configuration at the junction of the cervix and lower uterine segment, with the left gonadal vein crossing midline, and two previously known right leiomyomas now appearing on the left. These findings were consistent with the diagnosis of uterine torsion. She then underwent an urgent exploratory laparotomy, and the uterus was found to be dextroverted 270 degrees, with dark mottled purple tissue and engorged vessels. A supracervical hysterectomy and bilateral salpingo-oopherectomy were performed. Final pathology demonstrated extensive necrosis. This case reviews the classic presentation and imaging findings for the rare diagnosis of uterine torsion and options for management of both non-gravid and gravid patients.

Survival impact of bowel resection at the time of interval cytoreductive surgery for advanced ovarian cancer.

OBJECTIVES: To evaluate the impact of bowel resection at the time of interval cytoreductive surgery on survival. METHODS: We identified patients with advanced ovarian cancer who underwent neoadjuvant chemotherapy and interval cytoreductive surgery between 2008 and 2018 from a single-institution tumor registry. Kaplan-Meier survival analysis and Cox proportional hazards models were performed comparing patients who underwent bowel resection to those who did not. RESULTS: Of 158 patients, 43 (27%) underwent bowel resection. Rates of optimal (95%) and sub-optimal (5%) resection did not differ with bowel resection. Patients that required bowel resection had worse three-year survival (43% vs. 63%), even after adjusting for confounding variables of age, stage, number of neoadjuvant cycles, R0 resection, and ASA score (HR 2.27, p < 0.01). Adjusted progression-free survival did not differ between groups (HR 0.92, p = 0.72). Patients who underwent bowel resection were more likely to require blood transfusion (p < 0.01), and have a longer hospital stay (5 days vs 7.5 days, p < 0.01). CONCLUSIONS: Bowel resection at the time of interval cytoreduction confers a greater than 2-fold increased risk of mortality and does not impact progression-free survival. Long-term sequelae of the peri-operative morbidity of bowel resection may contribute to increased mortality, and bowel resection may be a surrogate for disease biology with poor prognosis.

Breakdown in the expedited partner therapy treatment cascade: from reproductive healthcare provider to the pharmacist.

BACKGROUND: The rising incidence rates of sexually transmitted infections in the United States highlight the need for concurrent treatment of patients and their sexual partners. Expedited partner therapy allows healthcare providers to offer antibiotic prescriptions or medications to an index patient for distribution to their sexual partner(s) without evaluating the partner. We hypothesized that there was a gap between expedited partner therapy policy at the state level and its downstream implementation by community pharmacists. OBJECTIVE: The objectives of our study were to evaluate pharmacists' expedited partner therapy knowledge and practices in 41 expedited partner therapy-permissible US states, to determine whether there were differences in practice based on the length of time expedited partner therapy was permissible in the state and chlamydia incidence rates, and to measure the cost of expedited partner therapy treatment. STUDY DESIGN: A randomized cohort of pharmacists (n=335) was invited to complete a telephone interview from November 2017 through January 2018. Descriptive statistics were calculated and stratified by early, mid, and late expedited partner therapy-adopter status based on the year of the state's expedited partner therapy enactment and the state's chlamydia incidence rate. Fisher's exact test and 1-way analyses of variance were used to compare measures across strata. RESULTS: We had 143 pharmacists (42.7%) agree to complete the survey. Among our respondents, 40.6% (n=58/143) indicated that they were aware of expedited partner therapy; 14.7% (n=21/143) reported that they had ever received an expedited partner therapy prescription, and 97% (n=139/143) reported that they would dispense an expedited partner therapy prescription if they received 1 in the future. These findings were stable across the 6 strata defined by early, mid, or late expedited partner therapy-adopter and high or low incidence rates of chlamydia status. Mean cost of azithromycin 1000 mg and cefixime 400 mg for treatment of chlamydia and gonorrhea was $22.17 (95% confidence interval, 20.29-24.05) and $30.46 (95% confidence interval, 28.65-32.26), respectively. CONCLUSION: Fewer than one-half of the pharmacists were aware of expedited partner therapy. A small minority of pharmacists reported ever having received an expedited partner therapy prescription, regardless of the length of time expedited partner therapy had been legal in their states and the incidence of chlamydia. However, almost all pharmacists reported that they would dispense an expedited partner therapy prescription if they received 1. Additionally, costs were high for expedited partner therapy for self-pay patients. These data suggest that there are opportunities to increase expedited partner therapy utilization by healthcare providers, patients, and pharmacists.

Pharmacy-level barriers to implementing expedited partner therapy in Baltimore, Maryland.

BACKGROUND: Addressing record high rates of Chlamydia trachomatis incidence in the United States requires the utilization of effective strategies, such as expedited partner therapy, to reduce reinfection and further transmission. Expedited partner therapy, which can be given as a prescription or medication, is a strategy to treat the sexual partners of index patients diagnosed with a sexually transmitted infection without prior medical evaluation of the partners. OBJECTIVE: There are multiple steps in the prescription-expedited partner therapy cascade, and we sought to identify pharmacy-level barriers to implementing prescription-expedited partner therapy for Chlamydia trachomatis treatment. STUDY DESIGN: We used spatial analysis and ArcGIS, a geographic information system, to map and assess geospatial access to pharmacies within Baltimore, MD, neighborhoods with the highest rates of Chlamydia trachomatis (1180.25-4255.31 per 100,000 persons). Expedited partner therapy knowledge and practices were collected via a telephone survey of pharmacists employed at retail pharmacies located in these same neighborhoods. Cost of antibiotic medication in US dollars was collected. RESULTS: Census tracts with the highest Chlamydia trachomatis incidence rates had lower median pharmacy density than other census tracts (26.9 per 100,000 vs 31.4 per 100,000, P < .001). We identified 25 pharmacy deserts. Areas defined as pharmacy deserts had larger proportions of black and Hispanic or Latino populations compared with non-Hispanic whites (93.1% vs 6.3%, P < .001) and trended toward higher median Chlamydia trachomatis incidence rates (1170.0 per 100,000 vs 1094.5 per 100,000, P = .110) than non-pharmacy desert areas. Of the 52 pharmacies identified, 96% (50 of 52) responded to our survey. Less than a fifth of pharmacists (18%, 9 of 50) were aware of expedited partner therapy for Chlamydia trachomatis. Most pharmacists (59%, 27 of 46) confirmed they would fill an expedited partner therapy prescription. The cost of a single dose of azithromycin (1 g) ranged from 5.00 to 39.99 US dollars (median, 30 US dollars). CONCLUSION: Limited geographic access to pharmacies, lack of pharmacist awareness of expedited partner therapy, and wide variation in expedited partner therapy medication cost are potential barriers to implementing prescription-expedited partner therapy. Although most Baltimore pharmacists were unaware of expedited partner therapy, they were generally receptive to learning about and filling expedited partner therapy prescriptions. This finding suggests the need for wide dissemination of educational material targeted to pharmacists. In areas with limited geographic access to pharmacies, expedited partner therapy strategies that do not depend on partners physically accessing a pharmacy merit consideration.

Validation of an atomic absorption rubidium ion efflux assay for KCNQ/M-channels using the ion Channel Reader 8000.

M-channels (M-current), encoded by KCNQ2/3 K(+) channel genes, have emerged as novel drug targets for a number of neurological disorders. The lack of direct high throughput assays combined with the low throughput of conventional electrophysiology (EP) has impeded rapid screening and evaluation of K(+)-channel modulators. Development of a sensitive and efficient assay for the direct measurement of M-current activity is critical for identifying novel M-channel modulators and subsequent investigation of their therapeutic potential. Using a stable CHO cell line expressing rat KCNQ2/3 K(+) channels confirmed by EP, we have developed and validated a nonradioactive rubidium (Rb(+)) efflux assay in a 96-well plate format. The Rb(+) efflux assay directly measures the activity of functional channels by atomic absorption spectroscopy using the automated Ion Channel Reader (ICR) 8000. The stimulated Rb(+) efflux from KCNQ2/3-expressing cells was blocked by the channel blockers XE991 and linopirdine with IC(50) values of 0.15 microM and 1.3 microM, respectively. Twelve compounds identified as KCNQ2/3 openers were further assessed in this assay, and their EC(50) values were compared with those obtained with EP. A higher positive correlation coefficient between these two assays (r = 0.60) was observed than that between FlexStation membrane potential and EP assays (r = 0.23). To simplify the assay and increase the throughput, we demonstrate that EC(50) values obtained by measuring Rb(+) levels in the supernatant are as robust and consistent as those obtained from the ratio of Rb(+) in supernatant/lysate. By measuring the supernatant only, the throughput of ICR8000 in an eight-point titration is estimated to be 40 compounds per day, which is suitable for a secondary confirmation assay.
