RESUMEN

PURPOSE: Adequate androgen levels are necessary for regular follicular growth, progression beyond the pre-antral stage, and prevention of follicular atresia. The main purpose of this study was to investigate whether baseline androgen levels had a predictive value on stimulation outcomes in IVF cycles. The secondary purpose was to compare the possible predictive value of androgens with that of already known markers. METHODS: The study included 91 infertile patients aged 30-45 years awaiting the first IVF cycle. All women underwent the same stimulation protocol and the same starting dose of recombinant FSH. As stimulation outcomes, the number of follicles recruited, estradiol and progesterone levels on the day of trigger, the total dose of gonadotropins administered, and the number of oocytes collected were recorded. Multiple linear regression and multivariate logistic regression were used to evaluate the significant predictive value of the variables for response to controlled ovarian stimulation (COS). By studying the reliability of different markers, an attempt was made to develop a single index with the highest predictive value. RESULTS: Pearson's correlation revealed a statistically significant inverse correlation between oocytes collected and age (r = - 0.333, p < 0.001) and a positive correlation with AMH (anti-müllerian hormone) (r = 0.360, p < 0.001), antral follicle count (AFC) (r = 0.639, p < 0.001), and androstenedione (Δ4-A) (r = 0.359, p < 0.001). No significant correlation was reported with FSH (r = - 0.133, p = 0.207) and total testosterone (r = 0.180, p = 0.088). In COS good responders, the G-index (= AMH ng/mL*AFC/Δ4-A ng/dL) revealed a significantly higher level (p < 0.001) than AMH, AFC, and Δ4-A alone. CONCLUSION: Baseline serum Δ4-A, presumably crucial for ensuring a regular follicular growth, is a reliable marker of ovarian response to stimulation. Since the ovarian capacity to respond to gonadotropins does not depend exclusively on the presence of follicles, we suggest a new index, the G-index, able to contemplate both the ovarian reserve and the Δ4-A level.

RESUMEN

To describe a rare case of unilateral massive hydrothorax after controlled ovarian stimulation for IVF and to analyze the diagnostic complexities in a patient lacking both risk factors and typical features of ovarian hyperstimulation syndrome (OHSS). We present a case of a 35-year-old woman suffering from primary infertility due to a severe male factor. Admitted to hospital for dyspnea, the patient initially underwent a thoracentesis. Later, due to the recurrence of massive hydrothorax, permanent pleural drainage was placed. Recognized as a severe manifestation of the OHSS, it was treated by pleural drainage, hydration, albumin perfusion, and management of the intercurrent pregnancy, up to improvement in clinical and hematological laboratory parameters and resolution of pleural effusion and respiratory symptoms. A total of 42 l of pleural fluid was drained during the 40 days of hospitalization. Since the pathogenesis of isolated acute hydrothorax in ovarian stimulation probably lies in the presence of anatomical defects of the diaphragm, this may justify that the relationship between this pathology and the OHSS risk factors may be less close. Massive pleural effusion may exceptionally be the only clinical presentation of OHSS. A high index of suspicion is necessary to make the correct diagnosis and to promptly administer treatment.

RESUMEN

OBJECTIVE: To evaluate rate and determinants of long-term recurrence of endometriosis in a population of young women. DESIGN: Retrospective cohort study. SETTING: University tertiary care referral center for women with benign gynecologic diseases. PARTICIPANTS: Young women undergoing first-line conservative surgery for endometriosis were eligible for the study. Data on age at surgery, disease stage, anatomical characteristics of endometriotic lesions, and endometriosis-related symptoms were collected. After diagnosis, patients were treated according to the standard care of the center. The protocol required all women to be followed up 1 month after surgery, and every 6 months afterward, with an interview to investigate persistence of symptoms, a clinical examination, and an ultrasound pelvic assessment. RESULTS: Fifty-seven women aged ≤ 21 (mean age at diagnosis ± SD: 19.0 ± 1.1 years) entered the study. During a 5-year follow-up, 32 (56%, 95% confidence interval [CI]: 43%-68%) recurrences of endometriosis were diagnosed. A second laparoscopy to treat the recurrence was performed in 11 (34%) cases and confirmed the presence of the disease in all of them. In the remaining 21 (66%) cases, the recurrence was based on the reappearance of the symptoms or clinical or sonographic findings. The recurrence rate increased constantly with time from first surgery. No association emerged between recurrence rate and endometriosis-related symptoms, site/stage of the disease, type of surgery, and post-surgical medical treatment. CONCLUSIONS: The recurrence rate of endometriosis in young women appears higher than in older women. Since no determinants for recurrence have been detected among the factors examined, a profile of women at increased risk cannot be drawn.

RESUMEN

OBJECTIVE: The objective of the study was to compare length of stay, blood loss, operative time, and pain of laparoscopic and vaginal hysterectomy. STUDY DESIGN: This was a prospective, randomized, controlled comparison between vaginal (VH) and laparoscopic (LH) hysterectomy among 60 consecutive patients with a uterine volume of 300 mL or less and without uterine prolapse. Patients were followed up for 12 months. RESULTS: The groups were significantly different for mean operative time (VH: 81 +/- 30 minutes; LH: 99 +/- 25 minutes; P = .033) and blood loss (LH: 83 +/- 57 mL; VH: 178 +/- 149 mL; P = .004). Bilateral adnexectomy was performed when preoperatively planned in 73% of cases of the vaginal arm, whereas it was always performed in the laparoscopic arm (P = .045). Postoperative pain on day 0 and the number of days of analgesic request were higher in the vaginal group (P = .023 and P = .017, respectively). LH was associated with a reduced hospital stay (LH: 2.7 +/- 0.5 days; VH: 3.2 +/- 0.6 days; P < .001).There were no differences between the groups at the follow-up. CONCLUSION: Laparoscopic hysterectomy results in a shorter hospital stay, less blood loss, and less postoperative pain compared with vaginal hysterectomy.

RESUMEN

OBJECTIVE: This study was undertaken to determine the frequency of postsurgical ovarian failure in patients undergoing laparoscopic excision of bilateral endometriomas. STUDY DESIGN: Patients who had been operated on for bilateral ovarian endometriosis between January 1995 and December 2003 and who were younger than 40 years at the time of surgery were contacted by telephone and interviewed. RESULTS: A total of 126 patients were recruited. Mean +/- SD age of patients at the time of surgery was 30.4 +/- 4.3 years. Postsurgical ovarian failure was documented in 3 cases, corresponding to a rate of 2.4% (95% CI 0.5%-6.8%). In all cases, this complication occurred immediately after surgery. CONCLUSION: Patients who had been operated on for bilateral endometriomas have a low but definite risk of premature ovarian failure occurring immediately after surgery.
