Misdiagnosis of cervical ectopic pregnancy.

PURPOSE: To determine the presenting symptoms as well as the frequency and reasons for the delayed diagnosis of cervical ectopic pregnancy (CEP) in order to increase detection and prevent treatment delay. METHODS: Retrospective case series of 15 women treated for CEP from January 1997 through December 2008 at a university teaching hospital. RESULTS: Fifteen patients were treated for CEP during the study period. Eight patients presented to the emergency department, of which 6 (75%) were initially misdiagnosed. The most common misdiagnosis was threatened miscarriage (n = 5). All patients with accurately diagnosed CEP presented with heavy vaginal bleeding; those misdiagnosed reported mild to moderate vaginal bleeding. Three of six patients misdiagnosed did not have an ultrasound performed upon presentation, and three patients had an ultrasound report not suggestive of CEP. CEP was diagnosed on follow-up ultrasound, delaying treatment 1-4 days. CONCLUSIONS: Misdiagnosis of CEP upon initial presentation is a common occurrence. Transvaginal ultrasound performed by a qualified practitioner may increase detection and prevent treatment delay.

Total laparoscopic hysterectomy with laparoscopic uterosacral ligament suspension for the treatment of apical pelvic organ prolapse.

Pelvic organ prolapse (POP) is a common problem requiring surgical correction in up to 19% of women. Abdominal sacrocolpopexy (SCP) is considered the gold standard treatment for apical POP and has been associated with lower rates of recurrent prolapse and dyspareunia compared with vaginal POP repair procedures. Total laparoscopic hysterectomy (TLH) with concurrent laparoscopic uterosacral ligament (USL) vaginal vault suspension provides a safe and effective alternative technique that has efficacy rates similar to abdominal SCP without the use of synthetic mesh. The uterosacral ligaments provide a strong supportive tissue for vaginal vault suspension that mimics the natural support system of the pelvic floor. The most challenging aspect of the TLH with laparoscopic USL suspension is laparoscopic suturing and intra/extracorporeal knot tying. Developing technologies such as robotics, automatic suturing devices, and new barbed suture materials are now providing simpler, alternative surgical techniques that will hopefully shorten operative times and increase adoption of this surgical procedure by gynecologists. With continued progress and refinement of this technique, the TLH with laparoscopic USL suspension may challenge the current standard of care for surgical treatment of POP.

Upregulation of insulin receptor substrate-2 in pancreatic beta cells prevents diabetes.

The insulin receptor substrate-2 (Irs2) branch of the insulin/IGF signaling system coordinates peripheral insulin action and pancreatic beta cell function, so mice lacking Irs2 display similarities to humans with type 2 diabetes. Here we show that beta cell-specific expression of Irs2 at a low or a high level delivered a graded physiologic response that promoted beta cell growth, survival, and insulin secretion that prevented diabetes in Irs2-/- mice, obese mice, and streptozotocin-treated mice; and that upon transplantation, the transgenic islets cured diabetes more effectively than WT islets. Thus, pharmacological approaches that promote Irs2 expression in beta cells, especially specific cAMP agonists, could be rational treatments for beta cell failure and diabetes.

Outpatient vaginal hysterectomy: optimizing perioperative management for same-day discharge.

OBJECTIVE: To present tactics for optimizing outpatient vaginal hysterectomy and describe perioperative outcomes in a large consecutive case series. METHODS: This is a descriptive study and review of clinical outcomes in 1,071 patients selected to undergo vaginal hysterectomy for benign indications from 2000 to 2010. The setting is a single-surgeon private practice in a community hospital. Outcome measures include length of hospital stay, estimated blood loss, operative time, uterine weight, and perioperative complications, including hospital readmissions and emergency room visits. RESULTS: One thousand seventy-one of 1,162 cases (92%, 95% confidence interval [CI] 90.5-93.7) were total vaginal hysterectomies, of which 1,029 (96%, 95% CI 94.9-97.3) were discharged the same day after surgery. The median operative time was 34 minutes (range 17-210 minutes), and estimated blood loss was 45 mL (range 5-800 mL). The median patient age was 46 years (range 27-86 years), and median uterine weight was 160 g (range 25-1,380 g). One hundred ninety-three patients (18%, 95% CI 15.8-20.5) were nulliparous and 218 (20%, 95% CI 18-22.9) had prior pelvic surgery. Five patients (0.5%, 95% CI 0.2-1.1) required readmission or emergency room evaluation within the first 30 days. CONCLUSION: Vaginal hysterectomy can be successfully adopted as a same-day discharge procedure. In this population, regardless of previous pelvic surgery or nulliparity, good perioperative outcomes have been achieved.

Conservative management of cervical ectopic pregnancy: utility of uterine artery embolization.

OBJECTIVE: To evaluate the use of uterine artery embolization (UAE) in conjunction with methotrexate in the conservative treatment of cervical ectopic pregnancy (CEP). DESIGN: Case series. SETTING: Tertiary-care university hospital. PATIENT(S): Cases of CEP treated at Hutzel Women's Hospital between January 1997 and December 2008. INTERVENTION(S): Multidose methotrexate treatment with or without UAE and intra-amniotic potassium chloride injection (KCl). MAIN OUTCOME MEASURE(S): Beta-human chorionic gonadotropin level, vaginal bleeding, length of hospital stay, and future fecundity. RESULT(S): A retrospective analysis of 15 patients with CEP treated conservatively using methotrexate with leucovorin rescue (MTx/Leu) alone (group 1, five cases), with UAE as an adjunctive therapy (group 2, six cases), or also having received intra-amniotic KCl before UAE (group 3, four cases) is reported. There was no significant difference in age, parity, or gestational age among treatment groups. The median ß-hCG level on presentation was 9,606 mIU/mL for group 1, 26,516 mIU/mL for group 2, and 130,464 mIU/mL for group 3. The difference was found to be statistically significant. No patients developed complications from UAE. Of the 10 patients who underwent UAE, 2 subsequently had confirmed viable pregnancies. CONCLUSION(S): Uterine artery embolization with methotrexate is an option for minimally invasive intervention in the treatment of CEP.
