Empty follicle syndrome is a condition in which no oocytes are retrieved after an apparently adequate ovarian response to stimulation and meticulous follicular aspiration. It is a rare condition of obscure etiology. A patient with primary infertility who underwent seven assisted reproductive technique cycles is described. In spite of a satisfactory ovarian response, aspiration yielded no oocytes in four cycles and 1-4 low quality oocytes in three cycles. In the index treatment cycle, ovulation was triggered using GnRH agonist 40 h prior to ovum pickup and hCG was added 6 h after the first trigger. Eighteen oocytes were recovered, of which 16 were mature and were inseminated by ICSI. Two embryos were transferred 48 h after aspiration and nine embryos were cryopreserved. The patient conceived and delivered a healthy boy at 38 weeks of gestation. The literature is reviewed and possible etiologies and treatment options of this enigmatic syndrome are suggested.

Higher amniotic fluid MMP-2 and TIMP-2 levels are found in women who eventually develop preeclampsia.

BackgroundIn-vitro fertilization is a known risk factor for ectopic pregnancies. We sought to establish the risk factors for ectopic pregnancy in GnRH antagonist cycles examining patient and stimulation parameters with an emphasis on ovulation trigger.MethodsWe conducted a retrospective, cohort study of 343 patients undergoing 380 assisted reproductive technology (ART) cycles with the GnRH antagonist protocol and achieving a clinical pregnancy from November 2010 through December 2015.ResultsSignificant risk factors for ectopic pregnancy in the univariate analysis included prior Cesarean section (CS), endometriosis, mechanical factor infertility, longer stimulation, elevated estradiol and progesterone levels, GnRH agonist trigger, higher number of oocytes aspirated, and insemination technique. Independent risk factors for ectopic pregnancy in the multivariate analysis included GnRH agonist trigger, higher number of oocytes aspirated, insemination technique, and prior Cesarean section.ConclusionExcessive ovarian response, IVF (as opposed to ICSI), prior Cesarean section and GnRH agonist trigger were found to be independent risk factors for ectopic pregnancy. Caution should be exercised before incorporating the GnRH agonist trigger for indications other than preventing OHSS. When excessive ovarian response leads to utilization of GnRH agonist trigger, strategies for preventing ectopic pregnancy, such as a freeze all policy or blastocyst transfer, should be considered. Further studies should elucidate whether adjusting the luteal support can reduce the ectopic pregnancy risk.

This study provides evidence that both continuous and intermittent epidural infusion produce comparable analgesia achieving equivalent maternal satisfaction with no difference regarding the duration of labor between them. Although patients receiving epidural analgesia experienced longer labors compared with controls, both mothers and neonates were unharmed.

Background: Deliberate self-poisoning (DSP) is a major health problem with increasing incidence mainly among young people. Objective: To examine the clinical and toxicological characteristics of DSP, it is compared to unintentional (non-DSP) exposures and those characteristics which might be associated with increased toxicological risk are identified. Methods: Two-year retrospective poison centre chart review. Statistics: χ2 analysis. Results: 3802 DSP cases were reported. Most calls (95%) were made by physicians compared to 51%) in non-DSP exposures, P <0.0001. There were almost twice as many females as males, contrary to unintentional exposures (P <0.001). Peak frequency involvement was at the age of 15-20 years for females and older for males. Only 19.8%) of DSP calls were made within the first hour of exposure compared to 46%) of the non-DSP calls (P <0.001). Younger patients tended to present earlier. The vast majority of exposures occurred by ingestion and at home. Pharmaceuticals and chemicals were involved in 86% and 12% of DSP cases, respectively (compared to 29% and 44% in non-DSP exposures, respectively, P <0.001). Psychiatric drugs were more commonly used in older age groups and analgesics among the younger. Insecticides, sodium hypochlorite and rodenticides were the most frequently used chemicals. Neurological involvement was observed in 48.2% of DSP patients compared to 16.9% in non-DSP exposures. DSP was associated with greater severity than non-DSP exposures (21% and 10% had moderate to severe toxicity, respectively, P <0.001). Severity was greater among males, aged older than 45 years, with time from exposure to consultation 8 hours or longer and with exposure to chemicals, psychiatric drugs or combinations. Conclusions: Most DSP patients were females, aged 15-20 years, used pharmaceuticals and had neurological involvement. Males, aged over 45 years, with longer time to toxicology consult and the use of chemicals were associated with increased severity. These parameters should alert the treating physician to the possibility of a poor course and hence to a more aggressive therapeutic approach.

The aim of this study was to compare maternal and neonatal outcome of twin births according to mode of delivery and to isolate the factors predicting a successful vaginal delivery and those predicting a failed trial of labor (TOL) leading to an emergent cesarean section. We reviewed all twin deliveries during the years 1995 to 2004. Parameters studied include maternal age, parity, gestational age, maternal antepartum complications and postpartum complications, fetal presentations, birthweight, mode of delivery of each twin, Apgar scores and cord pH. During the study period there were 40,710 deliveries of which 804 (1.9%) were twin deliveries. Of the 804 twins, 398 (49.5%) had planned cesarean sections (PCS) and 406 (50.5%) entered a TOL. Maternal age and parity were similar among the groups. Neonatal outcomes and postpartum complications did not differ between the groups. Of 406 women who had a TOL, 84.9% eventually delivered both twins vaginally. A significantly higher percentage of antepartum complications were noted among those who failed the TOL compared to those with successful TOL (8.2% vs. 1.7%, p = .01). The number of neonates with pH of less than 7.0 did not differ between the groups although more neonates (2.5% vs. 0.4%, p = .05) among the failed TOL had an Apgar score of less than 7.0 at 5 minutes compared to successful TOL. Vaginal delivery of both twins after TOL occurred in 91% of vertex/vertex compared with 71.8% of vertex/nonvertex presenting twins (p < .01). Neonatal outcomes did not differ between both groups. Our results indicate that both vaginal and PCS are comparable options for vertex presenting first twin regardless of second twin presentation.
