While women await surgery for type I endometrial cancer, depot medroxyprogesterone acetate reduces tumor glandular cellularity.

BACKGROUND: Multiple population-level studies have demonstrated an adverse effect of long wait times to surgery on survival for women with endometrial cancer. Other retrospective and nonrandomized prospective studies have shown that preoperative administration of depot medroxyprogesterone acetate decreases tumor glandular cellularity, which may be a surrogate marker for clinically meaningful tumor response. OBJECTIVE: We sought to determine whether preoperative injection with depot medroxyprogesterone acetate decreases tumor glandular cellularity when compared to placebo injection in women awaiting hysterectomy for endometrial intraepithelial neoplasia or type I endometrial cancer, and to determine whether depot medroxyprogesterone acetate injection affects quality of life while waiting for surgery. STUDY DESIGN: This was a double-blind, randomized controlled trial of 400-mg depot medroxyprogesterone acetate injection or 0.9% saline injection at the preoperative visit. Patients with recent use of progesterone analogs were excluded. A sample size of 76 patients (38 per arm) was calculated to detect a 20% difference in decreased glandular cellularity between arms. Pathologic characteristics including the primary outcome, tumor glandular cellularity, from patients' diagnostic biopsies were reviewed by 2 dedicated gynecologic pathologists and compared to posttreatment hysterectomy specimens. On the night prior to surgery, patients completed the Functional Assessment of Cancer Therapy-Endometrial Survey (Version 4) to report quality of life while waiting for surgery. In comparing characteristics between the intervention and control groups, t tests were used for continuous variables, and χ2 or Fisher exact tests were used where appropriate for categorical data. RESULTS: From March 2015 through March 2016, 148 women were screened and 76 patients were enrolled. In all, 38 patients were randomized to and received depot medroxyprogesterone acetate injection and 38 were randomized to and received placebo injection. Demographics were similar between groups. Patients who received depot medroxyprogesterone acetate injection experienced a larger decrease in tumor glandular cellularity (mean change -64 [-31.8%] vs -14 [-5.5%] cells per quarter high-powered field in depot medroxyprogesterone acetate vs placebo groups, P = .002). This effect was most pronounced in women waiting ≥3 weeks for surgery. Several additional histologic and immunohistochemical markers of tumor differentiation and decreased cell proliferation were more pronounced in the depot medroxyprogesterone acetate group than in the placebo group. There were no significant differences in quality of life between groups on the Functional Assessment of Cancer Therapy-Endometrial Survey. Only 5.3% of patients who were approached declined to participate due to concerns regarding an intramuscular injection. CONCLUSION: Administration of depot medroxyprogesterone acetate prior to surgery for type I endometrial cancers caused greater tumor effect than placebo injection. Injection of depot medroxyprogesterone acetate was acceptable to and well tolerated by patients. Depot medroxyprogesterone acetate may represent a meaningful bridge to surgery in women who can expect long wait times.

Uterine Sarcoma Presenting with Sepsis from Clostridium perfringens Endometritis in a Postmenopausal Woman.

Clostridium perfringens is an anaerobic gram positive rod that is found in normal vaginal and cervical flora in 1-10% of healthy women. Uterine infection with Clostridium perfringens is seen rarely but is often related to underlying uterine pathology and can progress quickly to sepsis. Early recognition of sepsis, prompt treatment with antibiotics, and source control with surgical management allow for optimal chance of recovery. We present a case of a postmenopausal woman who presented with sepsis, vaginal bleeding, and back pain who was found to have Clostridium perfringens infection in the setting of undifferentiated uterine sarcoma.

Trauma patients who present in a delayed fashion: a unique and challenging population.

BACKGROUND: A proportion of trauma patients present for evaluation in a delayed fashion after injury, likely due to a variety of medical and nonmedical reasons. There has been little investigation into the characteristics and outcomes of trauma patients who present delayed. We hypothesize that trauma patients who present in a delayed fashion are a unique population at risk of increased trauma-related complications. MATERIALS AND METHODS: This was a retrospective review from 2010-2015 at a Level I trauma center. Patients were termed delayed if they presented >24 hours after injury. Patients admitted within 24 hours of their injury were the comparison group. Charts were reviewed for demographics, mechanism, comorbidities, complications and outcomes. A subgroup analysis was done on patients who suffered falls. RESULTS: During the 5-y period, 11,705 patients were admitted. A total of 588 patients (5%) presented >24 h after their injury. Patients in the delayed group were older (65 versus 55 y, P < 0.001) and more likely to have psychiatric comorbidities (33% vs. 24%, P = 0.0001) than the control group. They were also more likely to suffer substance withdrawal (8.9% vs. 4.1%, P < 0.001) but had toxicology testing for drugs and alcohol done at significantly lower rates. Patients that presented delayed after falls were similar in age and injury severity score (ISS) but more likely to suffer substance withdrawal when compared to those with falls that presented within 24 hours. Patients with falls that presented delayed had toxicology testing at significantly lower rates than the comparison group. CONCLUSIONS: Trauma patients that present to the hospital in a delayed fashion have unique characteristics and are more likely to suffer negative outcomes including substance withdrawal. Future goals will include exploring strategies for early intervention, such as automatic withdrawal monitoring and social work referral for all patients who present in a delayed fashion.

Airflow limitations in pregnant women suspected of sleep-disordered breathing.

BACKGROUND AND AIM: Pregnancy physiology may predispose women to the development of airflow limitations during sleep. The goal of this study was to evaluate whether pregnant women suspected of sleep-disordered breathing (SDB) are more likely to have airflow limitations compared to non-pregnant controls. METHODS: We recruited pregnant women referred for polysomnography for a diagnosis of SDB. Non-pregnant female controls matched for age, body mass index (BMI), and apnoea-hypopnoea index (AHI) were identified from a database. We examined airflow tracings for changes in amplitude and shape. We classified airflow limitation by (a) amplitude criteria defined as decreased airflow of > or =10 s without desaturation or arousal (FL 10), or decreased airflow of any duration combined with either 1-2% desaturation or arousal, (FL 1-2%); and (b) shape criteria defined as the presence of flattening or oscillations of the inspiratory flow curve. RESULTS: We identified 25 case-control pairs. Mean BMI was 44.0±6.9 in cases and 44.1±7.3 in controls. Using shape criteria, pregnant women had significantly more flow-limited breaths throughout total sleep time (32.4±35.8 vs. 9.4±17.9, p<0.0001) and in each stage of sleep (p<0.0001) than non-pregnant controls. In a subgroup analysis, pregnant women without a diagnosis of obstructive sleep apnoea (OSA) who had an AHI <5 had similar findings (p<0.0001). There was no difference in airflow limitation by amplitude criteria between pregnant women and controls (p=0.22). CONCLUSIONS: Pregnant women suspected of OSA have more frequent shape-defined airflow limitations than non-pregnant controls, even when they do not meet polysomnographic OSA criteria.
