Screening for Down syndrome in dichorionic twin pregnancies conceived by in vitro fertilization (IVF): a clinical pilot study to confirm the laboratory methods.

PURPOSE: The corrections necessary to estimate the risk for Down syndrome in twin pregnancies have been pointed out. We performed a nested controlled study to evaluate the validity of these corrections in dichorionic twins conceived by IVF. METHODS: Detailed clinical data was collected from the medical records. Twins were matched with a contemporaneous cohort of spontaneously conceived singleton pregnancies that serve as reference in a 1 to 4 ratio. All patients had their entire obstetrical care at our Hospital. The Student t-test was used for group comparisons and a p-value <0.05 was considered significant. RESULTS: Nineteen sets of normal twins concordant in size and with appropriate weight for gestational age were matched with 80 normal and mature newborns. Significant differences between groups were found for maternal age, gestational age at delivery and newborn weight (all p < 0.01). No statistical differences were noted for the levels of the biochemical markers expressed as multiples of the median. However, a 15 % closer approximation to the laboratory median for PAPP-A and a 10 % closer approximation to the laboratory median for free ß-hCG was evident in twins when compared to the reference group. CONCLUSIONS: These findings support the methods used to estimate the risk for Down syndrome in dichorionic twin pregnancies conceived after IVF. A future study with a larger sample size could confirm if the laboratory corrections done on the combined screening test improve the predictability of Down syndrome in dichorionic twin pregnancy conceived by IVF when compared to singleton pregnancies.

Ibrexafungerp for the Treatment of Vulvovaginal Candidiasis: Design, Development and Place in Therapy.

Vulvovaginal candidiasis (VVC) is experienced by an estimated 75% of women at least once in their lifetime and is recurrent, defined as three or more infections per year (RVVC) in 5-9%. Candida albicans is the most common causative agent, but up to 19% of infections may be related to non-albicans species. Available treatment options for VVC have consisted of oral and topical azoles (except for topical nystatin, a polyene). Oral polyenes are not absorbed and therefore not effective for VVC. Fluconazole is the only oral medication FDA approved for VVC. None of these treatments are FDA approved for RVVC. Ibrexafungerp, a triterpenoid fungicidal agent, was FDA approved in 2021, becoming the first oral non-azole agent for VVC. Ibrexafungerp reaches concentrations up to 9-fold higher in vaginal tissues versus plasma. In Phase 2 clinical trials, ibrexafungerp had a clinical cure rate comparable to fluconazole at day 10, but significantly better at day 25. In Phase 3 clinical trials, ibrexafungerp had both a higher clinical and mycologic cure rate versus placebo at both days 10 and 25. In December 2022, Ibrexafungerp received FDA approval for once monthly dosing to decrease the incidence of RVVC. This approval was based on data from the CANDLE STUDY, which showed 65.4% resolution of symptoms and culture negative success through week 24, compared to 53.1% of placebo. Ibrexafungerp provides an alternative oral option for treatment of acute, severe VVC. It is the only FDA approved antifungal for RVVC. Currently, the population likely to benefit from this drug are those with azole allergy, non-albicans or azole resistant albicans species, or other azole contraindications such as drug interactions (like statins or tricyclics). Side effects are mostly gastrointestinal and mild in nature. Ibrexafungerp, like fluconazole, should be used with caution in women who are or may become pregnant.

A Discussion of High-Risk HPV in a 6-Year-Old Female Survivor of Child Sexual Abuse.

BACKGROUND: Human papilloma viruses (HPVs) cause a variety of clinical manifestations in children including skin warts, laryngeal papillomas, and condyloma acuminatum. Whereas the mode of transmission is well understood and management of HPV infection is clearly defined by guidelines in adults, less is known about the mode of transmission, natural history of disease, and appropriate management of high-risk anogenital HPV infections in children. CASE: The patient is a previously healthy 6-year-old female who presented with multiple vaginal lesions causing pain and discomfort and was diagnosed with HPV 18 positive CIN I. SUMMARY AND CONCLUSION: Children infected with high-risk HPV subtypes remain a vulnerable patient population, and there is minimal literature on the natural history of disease and effects of overtreatment. Based on a literature review, conservative management, HPV vaccination, and consideration of the cervical cancer screening guidelines for adolescent females are an appropriate treatment course until more studies are reported on cervical cancer screening in survivors of child sexual abuse.

Contraception pathway: application for midlife women.

OBJECTIVE: To create a system where evidence based medicine can be applied to accommodate every woman's needs by designing a contraceptive pathway that can be utilized by any healthcare provider, regardless of the patient's age, and to offer appropriate counseling in order to maximize patient outcomes, especially for the midlife woman. METHODS: United States Medical Eligibility Criteria for Contraceptive Use, 2016 (US MEC) was used as the framework for these recommendations for a contraceptive care pathway that can be incorporated into care for midlife women. DISCUSSION: By utilizing a total office approach that includes the scheduler, receptionist, medical assistant, nurse and health care provider as members of a team, the entire spectrum of the patient population in need of contraception from teenagers to midlife can be captured. Specifically for midlife women the need for an effective form of contraception may be overlooked as fecundity declines in this age group. This paper will highlight the use of this pathway for midlife women.
