RESUMEN

OBJECTIVE: We used a new optical imaging technique to compare human intravaginal coating distributions of Conceptrol (Advanced Care Products, Brunswick, NJ) and Advantage (Columbia Laboratories, Aventuna, FL). These gels are surrogates for future microbicidal gels, differing in molecular structures and biophysical properties. METHODS: For each protocol, a 3-mL gel bolus was inserted to the posterior fornix while the woman was in the supine position. She then either (1) remained supine (10 min); or (2) sat up (1 min), stood up (1 min), sat down (1 min) and returned to supine for a net elapsed time of 10 min. The imaging device is sized/shaped like a phallus, and measurements while the device was inserted provide data that simulate peri-intromission coating. RESULTS: Coating by Advantage was more extensive and uniform than coating by Conceptrol, with smaller bare spots of uncoated epithelium. Change in posture tended to increase extent and uniformity of coating, details differing between gels. CONCLUSIONS: Results are consistent with predictions of mechanistic coating theory, using gel rheological data as inputs.

RESUMEN

OBJECTIVE: To discuss the possible role of abnormal embryo migration as a cause of ectopic pregnancy during IVF with hydrosalpinges. DESIGN: Case report. SETTING: University-based reproductive endocrinology and fertility clinic. PATIENT(S): A patient presenting with a tubal ectopic pregnancy after spontaneous conception in a preexisting hydrosalpinx. INTERVENTION(S): Laparoscopic salpingectomy. MAIN OUTCOME MEASURE(S): Ultrasound and operative findings. RESULT(S): Case demonstration of abnormal embryo migration into a surgically documented preexisting hydrosalpinx during a spontaneous conception. CONCLUSION(S): The mechanism of increased tubal ectopic pregnancy rates during IVF with hydrosalpinges remains unexplained. This case supports abnormal embryo migration due to the hydrosalpinx as a contributing factor.

RESUMEN

OBJECTIVE: This study, which was the first evaluation in Australia of multiple-family group treatment, explored the effectiveness of this approach for a newly arrived non-English speaking migrant group, first-generation Vietnamese families, and for English-speaking families. METHODS: Thirty-four pairs of English-speaking consumers and family members and 25 Vietnamese-speaking pairs were randomly assigned to a multiple-family group or a control group. All consumers had a diagnosis of schizophrenia. The multiple-family group intervention (26 sessions over 12 months) was delivered as an adjunct to case management services, which all consumers received. Outcomes, which were measured immediately after treatment and 18 months later, included the number of relapse episodes; the presence and severity of symptoms, as measured by the Brief Psychiatric Rating Scale (BPRS) and the Scale for the Assessment of Negative Symptoms; and social functioning, as measured by the Family Burden Scale, the Health of the Nation Outcome Scale, and the Quality of Life Scale. RESULTS: Relapse rates immediately after treatment were significantly lower for the multiple-family group than for the control group (12 and 36 percent), and relapse rates were also lower during the follow-up period (25 and 63 percent). BPRS ratings were significantly lower for participants in the multiple-family group, and vocational outcomes also improved. The reductions in relapse and symptoms were similar for the English-speaking and the Vietnamese-speaking family groups; sample size precluded statistical analysis of differences. CONCLUSIONS: Multiple-family group treatment is an effective cognitive-behavioral intervention in the treatment of schizophrenia. The findings suggest continued application of and research on family interventions for non-English speaking migrant populations.

RESUMEN

OBJECTIVE: To test the hypothesis that pregnancy rates are low if grade Z1 pre-embryos are not available for transfer and to determine if pronuclear morphology is a better predictor of pregnancy than traditional embryo morphology. DESIGN: Prospective clinical study. SETTING: Academic human reproduction laboratory. PATIENT(S): One hundred couples undergoing IVF with conventional insemination or ICSI. INTERVENTION(S): Embryo quality was assessed using both pre-embryo pronuclear morphology (zygote scoring or Z-scoring) at the time of fertilization evaluation and standard day 2 and day 3 embryo morphology (number of blastomeres and grading based on degree of fragmentation and blastomere size). MAIN OUTCOME MEASURE(S): We tested two decision models, one based on Z-scores and another on morphology, to determine which grading system better predicted pregnancy outcomes in assisted reproductive technique. Zygote score and embryo morphology were measured for all embryos and the transferred embryo pool. Implantation and pregnancy rates resulting from the embryo transfers of all cycles were calculated. RESULT(S): The Z-score distribution of 552 embryos was 27% Z1, 8% Z2, 50% Z3, and 15% Z4. Z1 and Z3 embryos had significantly (P approximately .03) higher quality over Z2 and Z4 embryos. Using the Z-score decision model with Z1 embryos having highest priority for transfer, pregnancy rates were similar between Z1 and Z3 embryos. Using embryo morphology as a decision model, pregnancy rates were highest in transfers containing one or two "best"-quality embryos. CONCLUSION(S): Z1 and Z3 embryos had similar morphology and pregnancy rates. The decision model based on the Z-score model was not better than standard embryo morphology in predicting pregnancy outcome.

RESUMEN

OBJECTIVE: To test the hypothesis that couples with sperm chromatin structure assay (SCSA) DNA fragmentation index (DFI) values >27% would not achieve pregnancy with assisted reproductive techniques (ART) and to investigate how DFI and high DNA stainability (HDS), as measured by the SCSA, affect fertilization, cleavage, implantation, and pregnancy rates in IVF cycles. DESIGN: Prospective clinical study. SETTING: Academic human reproduction laboratory. PATIENT(S): One hundred couples undergoing IVF with conventional insemination or intracytoplasmic sperm injection. INTERVENTION(S): Testing with SCSA was performed by SCSA Diagnostics (Brookings, South Dakota) on a semen aliquot taken from ejaculate used for ART. MAIN OUTCOME MEASURE(S): Relating total DFI and HDS to conventional semen parameters and cycle-specific outcomes after ART. RESULT(S): Nine of nineteen couples achieved clinical pregnancy when DFI was > or =27%, and 2 of 22 couples achieved clinical pregnancy when DFI was < or =9%. One of nine couples achieved clinical pregnancy with HDS >17%. The DFI was negatively correlated with sperm density (r = -0.23, P<.03) and motility (r = -0.55, P<.00), and HDS was negatively correlated with sperm density (r = -0.37, P<.00). CONCLUSION(S): Sperm chromatin structure assay failed to identify elevated DFI thresholds for negative pregnancy outcome after ART. Patients with low DFI (< or =9%) were least likely to become pregnant, which is also contradictory to SCSA marketing, which states that DFIs of < or =15% have excellent fertility potential. Patients with HDS > or =17% had low pregnancy rates, indicating decreased fertility potential, which deserves further investigation. Larger studies are necessary to confirm that low DFI is associated with decreased fertility and, if proved, might redefine the use of the SCSA in evaluating infertility.

RESUMEN

OBJECTIVE: To demonstrate that folliculogenesis can be sustained with 200 IU human chorionic gonadotropins (hCG) after FSH-priming and result in pregnancy in women with estrogenic ovulatory dysfunction and risk factors for severe ovarian hyperstimulation syndrome (OHSS). CASE REPORT: Three women with infertility associated with estrogenic ovulatory dysfunction and hyperinsulinemia who appeared to be at high risk for severe OHSS during gonadotropin therapy. INTERVENTIONS: After 10 days of receiving either 150 IU hMG or recombinant FSH, patients were switched to 200 IU hCG/day alone for 2-3 days. 5,000 IU of hCG was then administered followed by either home intercourse, intrauterine insemination or transvaginal oocyte retrieval-embryo transfer. MAIN OUTCOME MEASURES: Endovaginal ultrasound measurement of follicle number and size, serum estradiol levels, symptoms of ovarian hyperstimulation, pregnancy test, and evaluation of pregnancy by transvaginal ultrasound. RESULTS: After discontinuation of hMG or recombinant FSH, serum estradiol concentrations continued to rise, and follicles >14 mm continued to grow during low-dose hCG administration. All women conceived without developing symptoms of OHSS. Pregnancy outcomes achieved include a term singleton delivery, a term twin delivery, and triplets delivered at 31 weeks gestation. CONCLUSION: The use of low-dose hCG alone is sufficient for supporting the late stages of folliculogenesis in women with estrogenic ovulatory dysfunction. This ovulation induction regimen appears to support the follicular growth of larger follicles while decreasing the number of smaller preovulatory follicles, thereby reducing a known risk factor for OHSS. We report on the positive pregnancy outcomes in 3 women with estrogenic ovulatory dysfunction and clinically appeared to be at high risk for developing severe OHSS who safely underwent this protocol.
