Gestational vitamin D3 supplementation and sun exposure significantly influence cord blood vitamin D status and 3-epi-25-hydroxyvitamin D3 levels in term newborns.

BACKGROUND AND AIMS: High prevalence of hypovitaminosis D is worldwide reported among pregnant women and newborns. We assessed cord blood 25-hydroxyvitamin D3 [25(OH)D3] and 3-epi-25-hydroxyvitamin D3 (C3-epimer) levels in relation to assumed maternal risk factors for hypovitaminosis D. METHODS: We enrolled 246 term newborns during summer. 175/246 mothers were supplemented with a daily variable dosage (200-1,000 IU) of vitamin D3 during pregnancy. Cord blood 25(OH)D3 and C3-epimer concentrations were analyzed by high performance liquid chromatography tandem mass spectrometry. RESULTS: Median cord blood 25(OH)D3 levels were 23.4 ng/mL (16.9-28.8). The prevalences of vitamin D sufficiency (≥ 30.0 ng/mL), insufficiency (20.0-29.9 ng/mL), and deficiency (< 20.0 ng/mL) were 19.9%, 45.9%, and 34.2%, respectively. Non-Caucasian ethnicity, housewife life, weight excess, negligible sun exposure and absent gestational vitamin D supplementation were associated with both reduced cord blood 25(OH)D3 and C3-epimer levels. C3-epimer/25(OH)D3 ratio was 15.1% (13.6%-18.4%) and it was not related to any of the assumed risk factors for hypovitaminosis D. CONCLUSIONS: Cord blood vitamin D deficiency was common, particularly in newborns from mother not receiving vitamin D supplementation and with poor sun exposure. C3-epimer levels were high in cord blood, causing possible misclassification of vitamin D status if they were not distinguished from 25(OH)D3 concentrations.

Seven-liter ovarian cyst in an adolescent treated by minimal access surgery: laparoscopy and open cystectomy.

Laparoscopic approaches to giant ovarian cysts, particularly in adolescents, have critical management concerns as follows: risk of malignancy, risk of cyst rupture, and limited working space. A 15-year-old girl presented with a giant (>25 cm) ovarian serous cyst adenoma containing 7 L of fluid. At open laparoscopy, a giant, entirely cystic, smooth mass originating from the right ovary and lying between the symphysis and the xiphoid was observed. After intraabdominal fluid aspiration, open conservative cystectomy was performed, avoiding spillage. The patient made an uneventful postoperative recovery and was discharged on the second postoperative day. To our knowledge, this is the largest ovarian cyst treated conservatively in an adolescent. Minimal access surgery, laparoscopy and open cystectomy, can be safely proposed in this group of patients. Conservative surgery should always be evaluated for preservation of ovarian function in cases of giant ovarian cysts in adolescents.

Endometriosis and infertility Surgery and ART: An integrated approach for successful management.

OBJECTIVES: Laparoscopy is considered the gold standard for treatment of endometriosis. In vitro fertilization and embryo transfer (IVF-ET) is often used to treat women with infertility associated with endometriosis. The objective of the study was to evaluate the pregnancy rate after surgical treatment and to assess whether a combined approach with laparoscopic surgery followed by IVF-ET can improve the "overall" pregnancy rate. STUDY DESIGN: A retrospective observational study was carried out on 107 infertile patients who underwent laparoscopic surgery for endometriosis and came at follow-up for a period of time between 1 and 11 years. Sixty-seven patients who did not become pregnant after surgery subsequently underwent IVF-ET. RESULTS: The pregnancy rate achieved after the integrated laparoscopy-IVF approach was 56.1%. The pregnancy rate after surgery, was significantly lower (37.4%). The fecundity rate for spontaneous conceptions within 6 months of laparoscopy (23.2%) was significantly higher (P<0.05) than for the following intervals. The cumulative fecundity in women older than 35 years was significantly lower than in younger women. CONCLUSIONS: In patients with endometriosis-associated infertility, surgery followed by IVF-ET is more effective than surgery alone. When patients fail to conceive spontaneously, after a maximum of 1 year from laparoscopic surgery, IVF should be suggested.

GnRH antagonists.

Ovarian stimulation is an important step in the success rate of in vitro fertilization (IVF) allowing multiple follicular growth, several oocytes and consequently more embryos. The combination of GnRH-antagonists (GnRH-ant) and gonadotrophins is now available for clinical use and represent a valid alternative to classical protocol with GnRH agonist. GnRH-antagonists induce a direct block of GnRH receptor with a rapid decrease in LH and FSH, preventing LH surge. Two protocols has been designed for assisted reproduction technology (ART) treatment: multiple-dose protocol and a single-dose. Both protocols are simply, efficacious, started in the late follicular phase and do not have side effects. A review of GnRH-antagonist applications in ART cycles are presented. Smaller doses of gonadotrophins, shorter stimulation period and lower ovarian hyperstimulation syndrome (OHSS) incidence are reported in literature using GnRH-antagonist compared to agonist. Triggering of ovulation, the use in polycystic ovarian syndrome (PCOS) and poor reponders patients are other interesting indication. Regarding to pregnancy rate and potentially adverse effects of drugs on endometrium or implantation needed more data.
