Vaginal laceration during coitus is not a rare occurrence; however, vaginal perforation from coitus is uncommon and occurs in less than 1% of nonobstetric genital tract injuries. Limited case reports exist discussing the recognition and management of vaginal perforation. Previously described management is commonly performed with laparotomy. We report a case of postcoital vaginal laceration and posterior fornix perforation in an adolescent with hemoperitoneum, pneumoperitoneum, and subsequent hypovolemic shock, and describe a laparoscopic approach for repair. Vaginal perforation with subsequent peritonitis and hemodynamic instability is a rare outcome in an adolescent who presents to the emergency department with pain or bleeding in the setting of recent penile intercourse. Delays in recognition can lead to further patient compromise, with potential morbidity or mortality. In this patient cohort, we suggest maintaining a high clinical suspicion for this sequela, and a low threshold for surgery with perforations greater than 1 cm. In the event that surgical management is warranted, we recommend a laparoscopic approach to increase visibility and to improve postoperative outcomes. [ABSTRACT FROM AUTHOR]

• Pomalidomide is possibly a replacement drug for myeloma patients refractory to lenalidomide. • Pomalidomide achieves responses among myeloma patients refractory to lenalidomide. • Clinical activity improves for myeloma patients receiving the 4-mg pomalidomide dose. The combination of pomalidomide with dexamethasone is approved for the treatment of relapsed/refractory multiple myeloma (RRMM). This phase 2, multicenter, open-label, non-randomized study investigated pomalidomide as a replacement for lenalidomide for 45 patients with RRMM refractory to a lenalidomide-containing combination regimen containing steroids and one or more other anti-myeloma agents administered using the same schedule(s), dose(s), and drug combination. Pomalidomide was administered on days 1–21 of a 28-day cycle for ≤8 cycles at a dose of 2, 3, or 4 mg. Overall response rates (ORRs) and clinical benefit rates (CBRs) were 33% and 44%, respectively, and were higher among those who received 4 mg pomalidomide (ORR 41% and CBR 50%). Median progression-free survival and overall survival were 8 and 16 months, respectively. Adverse events were consistent with the established safety profiles for the individual agents and the replacement of lenalidomide with pomalidomide did not appear to result in greater toxicity. Overall, this study indicates that pomalidomide can be an effective and safe replacement for lenalidomide among patients with RRMM refractory to the latter immunomodulatory agent without requiring additional changes to the combination regimen.

• Replacement of bortezomib or carfilzomib with ixazomib in RRMM was investigated • Patients continued use of the same drugs, dose, and frequency of non-PI regimen components. • Ixazomib was well tolerated but not efficacious and was unable to overcome PI resistance. Identifying effective combination regimens is a high priority in multiple myeloma (MM), as most patients eventually become refractory to their current treatments. In this study, we investigated whether the proteasome inhibitor (PI) ixazomib could delay disease progression among patients who failed regimens containing another PI, bortezomib or carfilzomib. This phase 1/2, multicenter, open-label, nonrandomized study enrolled patients who were refractory to a previous regimen containing bortezomib or carfilzomib. Patients continued the other anti-MM drugs in the regimen at the same doses and frequencies. Patients with combination regimens with unknown maximum tolerated dose (MTD) of ixazomib were enrolled in phase 1, with ixazomib starting at 3 mg and then dose escalated to 4 mg. Patients on regimens with a known ixazomib MTD were enrolled in phase 2. Primary endpoints were overall response rate (ORR), clinical benefit rate (CBR), adverse events (AEs), and determination of maximum tolerated dose (MTD). Of the 46 patients enrolled, 39 were evaluable for efficacy. ORR and CBR were 12.8% and 17.9%, respectively. Ixazomib appeared to be well tolerated as a replacement for carfilzomib and bortezomib, with 23.9% of patients experiencing at least one grade ≥3 serious adverse event (SAE) and 37.0% experiencing at least one grade ≥3 AE. The most common grade ≥3 AEs were hyponatremia (8.7%), anemia (8.7%), dyspnea (8.7%), thrombocytopenia (6.5%), dehydration (4.3%), and pneumonia (4.3%). The results indicate that ixazomib is not an effective replacement for bortezomib or carfilzomib for patients with MM who have previously relapsed on other bortezomib/carfilzomib-containing regimens.

Objective: To study the impact of both controlled ovarian hyperstimulation (COH) length and total gonadotropin (GN) dose individually and in concert on live birth rates (LBR) in both fresh and freeze-all in vitro fertilization embryo transfer (IVF-ET) cycles.Design: Historical cohort study.Setting: Not applicable.Patient(s): The U.S. national database from the Society of Assisted Reproductive Technology Clinic Outcome Reporting System from 2014 to 2015 was used to identify patients undergoing autologous GN stimulation IVF cycles with the use of GnRH antagonist-based suppression protocols where a single embryo transfer was performed as part of a fresh IVF-ET cycle (fresh, n = 14,866) or the first frozen embryo transfer after a freeze-all cycle (frozen, n = 2,964), and not including preimplantation genetic testing cycles. The patients' demographic and cycle characteristics, duration of COH, total GN dose, and pregnancy outcomes were extracted. Binomial regression models estimated trend and relative risk of live birth with respect to days of stimulation and total GN dose singularly, and after adjustment for a priori confounders including age, parity, body mass index, diagnosis, and maximum follicle-stimulating hormone in both fresh and frozen embryo transfer cycles. Both days of stimulation and total GN dose were then added to the multivariate model to show whether they were independently associated with LBR.Intervention(s): Not applicable.Main Outcome Measure(s): Live birth rate.Results: In both fresh and frozen cycles, length of COH was significantly associated with total GN dose. On univariate analysis, LBR decreased significantly with increasing length of stimulation and increasing total GN dose in both fresh and frozen cycles. On multivariable analysis including both days of stimulation and total GN dose, days of stimulation was no longer significantly correlated with LBR, whereas total GN dose remained significantly correlated with LBR in fresh cycles only. When total GN doses ranging from <2,000 IU through 5,000 IU to >5,000 IU were compared, a significant improvement in live birth rate was noted with lower total GN doses. Specifically, GN doses <2,000 IU had a 27% higher rate of live birth compared with GN dose >5,000 IU. For GN dose groups up to 4,000 IU, the estimated effect on LBR was similar. There was a marginal improvement (13%) in LBR with GN doses of 4,000 IU to 5,000 IU compared with >5,000 IU. When the multivariate model was applied to the frozen cycles, neither total GN dose nor days of stimulation was significantly associated with LBR.Conclusions: High total GN dose but not prolonged COH is associated with decreasing LBRs in fresh cycles, whereas neither factor significantly affects LBR in frozen cycles. Consideration should be given to minimizing the total GN dose when possible in fresh autologous cycles, either by decreasing the daily dose or by limiting the length of stimulation to improve LBRs. In freeze-all cycles, the use of higher GN doses does not seem to adversely affect the LBR of the first frozen embryo transfer. High total GN dose likely exerts a negative impact on the endometrium and/or oocyte/embryo unrelated to the length of stimulation. The differential effect of total GN dose on LBR in fresh and frozen cycles may imply a greater impact exerted on the endometrium rather than the oocyte. [ABSTRACT FROM AUTHOR]
