Sonohysterography for the diagnosis of residual trophoblastic tissue.

OBJECTIVE: To assess the efficacy, safety, and associated complications of sonohysterography for the diagnosis of residual trophoblastic tissue. METHODS: We conducted a prospective study of 23 consecutive patients admitted to our ultrasonography unit with clinical and ultrasonographic signs of retained intrauterine tissue. RESULTS: Twelve patients had hydrosonographic features suggestive of residual trophoblastic tissue (i.e., an intrauterine lesion not detachable from the uterine wall after instillation of saline), whereas in 11 cases the hydrosonographic findings were negative for retained tissue. Blood flow was detected within abnormal intrauterine masses in 4 of 12 patients with trophoblastic tissue, whereas it was not detected in any patient without retained tissue (P = .093). No complications were encountered during the procedure or the postprocedure period. None of the patients had anesthetic complications, perforation of the uterus, fluid overload, or any other surgical complication. All 12 patients underwent hysteroscopic removal of the suspected residual trophoblastic tissue, and histologic confirmation of residual trophoblastic tissue was obtained in all cases. CONCLUSIONS: Sonohysterography for detection and diagnosis of residual trophoblastic tissue is an accurate and safe procedure. Further studies comparing the efficacy of sonohysterography with that of diagnostic hysteroscopy are warranted.

Effect of publication of the "Practice Parameter for the management of hyperbilirubinemia" on treatment of neonatal jaundice.

UNLABELLED: The aim of this study was to evaluate the change in the treatment of neonatal jaundice following introduction of the "American Academy of Pediatrics' Practice Parameter for the management of hyperbilirubinemia in the healthy term newborn". In a historical control observation cohort study, we examined the rate of phototherapy and exchange transfusions among full-term (> or = 37 wk gestation) and near-term (gestational age between 35 and 37 wk and birthweight > 2000 g) infants in two community hospitals. The study included all consecutive infants born during two 15-mo study periods immediately before and after the introduction of the new guidelines. Data were prospectively recorded in a computerized database. The rate of phototherapy significantly decreased in the second study period from 7.9% (514/6499) to 2.9% (251/8650) (p < 0.0001) among full-term infants, and from 20.9% (102/489) to 9.4% (47/502) (p < 0.0001) in near-term infants. The use of exchange transfusion was significantly higher (p < 0.001) in the first compared to the second period: 0.2% (15/6499) vs 0.03% (3/8650). A significant decrease was found when the data from each hospital were analyzed separately. CONCLUSION: A significant decrease in the use of phototherapy and exchange transfusion occurred after the publication of the new practice parameters. This trend was observed for both term and preterm newborns, although the new guidelines were not intended for infants born before term.

In vitro fertilization following natural cycles in poor responders.

This prospective study was designed to examine the feasibility of natural cycle in vitro fertilization (IVF) in poor responders, and the clinical factors that may predict successful outcome. Twenty-two poor responders underwent IVF treatment with 44 unstimulated cycles. The results of the natural cycles were compared with those of the 55 low-response stimulated cycles of these patients during the 12 months prior to the study. Eighteen (82%) patients had at least one oocyte retrieved, while nine (41%) had at least one cycle with embryo transfer. Two (9%) patients each gave birth to a healthy term baby. These results are comparable with those of the stimulated cycles. Serum early follicular follicle stimulating hormone (FSH) level was found to be the only reliable predictor of oocyte recovery and overall outcome in each specific natural cycle. However, because of great variability in basal FSH levels among different cycles of the same patient, this is not a reliable predictor of outcome in future cycles. We conclude that poor responders are a unique group of patients who may benefit from natural-cycle IVF treatment.

Management of women with polycystic ovary syndrome who experienced premature luteinization during clomiphene citrate treatment.

OBJECTIVE: To determine the preferred treatment modality in patients with PCOS who experienced premature luteinization during CC treatment. DESIGN: Prospective randomized study. SETTING: Tertiary medical center. PATIENTS: Twenty-two infertile women with PCOS demonstrating premature luteinization during at least two consecutive CC cycles. INTERVENTIONS: Randomized induction of ovulation either with FSH alone or with GnRH agonist combined with FSH for a single treatment cycle. MAIN OUTCOME MEASURES: Premature luteinization was defined as serum progesterone >1.5 ng/mL before hCG administration. RESULTS: Premature luteinization occurred in eight of the 10 patients (80%) in group A and in two of the 12 patients in group B (16.6%). This result corresponds to the higher mean (+/-SD) progesterone level present in group A patients as compared to those in group B (2.0 +/- 1.2 ng/mL vs. 1.2 +/- 0.6 ng/mL, P=0.03). No pregnancies were achieved in group A, whereas the pregnancy rate per cycle observed in group B was 33.3% (4/12). On the day of hCG administration, the maximum mean (+/-SD) estradiol level was significantly lower (P<0.0001) in group A (210.6 +/- 37.9 pg/mL) than in group B (600.3 +/- 253.8 pg/mL). The treatment duration and the number of FSH ampules used did not differ between the groups. CONCLUSIONS: Pituitary desensitization with GnRH analog in combination with FSH is superior to FSH-only treatment in PCOS patients who demonstrate premature luteinization during CC treatment.

Ovarian remnant syndrome after laparoscopic oophorectomy.

OBJECTIVE: To report the surgical history, clinical characteristics, and operative technique used in patients with ovarian remnant syndrome after laparoscopic oophorectomy. DESIGN: Observational study. SETTING: Teaching hospital and private practice office. PATIENT(S): Nineteen patients with documented history of unilateral or bilateral laparoscopic oophorectomies with histologic confirmation of ovarian remnants. INTERVENTION(S): Operative laparoscopy for resection of ovarian remnants. MAIN OUTCOME MEASURE(S): Risk factors and surgical technique contributing to ovarian remnant syndrome. RESULT(S): The patients underwent a mean of 4.7 previous surgical procedures (range, two to nine): 12 had bilateral oophorectomy, and seven had unilateral oophorectomy. The infundibulopelvic ligament had been secured with bipolar desiccation in 11 patients, pretied surgical loops in six, and a linear stapler in two. Cystic ovarian remnants were identified by pelvic sonography in 12 women and by computed tomography (CT) scan in one. Six women underwent reoperation, two for ovarian remnants in different sites. CONCLUSION(S): With laparoscopic oophorectomy there is risk of ovarian remnant due to improper tissue extraction or misapplication or improper use of pretied surgical loops, linear stapler, or bipolar electrodesiccation on the infundibulopelvic ligament, especially in women with a history of multiple pelvic surgeries, adhesions, or endometriosis.

Preferred treatment of infertile women older than 37 years of age who demonstrate premature luteinization in the first evaluation cycle.

OBJECTIVE: To evaluate the efficacy of various treatments in abolishing premature luteinization in infertile women over 37 years old who are undergoing ovulation induction. DESIGN: Prospective, nonrandomized study. SETTING: Tertiary care medical clinic. PATIENT(S): Seventeen infertile women >37 years old in whom premature luteinization was detected during their evaluation (pretreatment) cycle. INTERVENTION(S): The patients underwent three consecutive treatment cycles with clomiphene citrate (group A), hMG (group B), and a GnRH agonist plus hMG (group C). MAIN OUTCOME MEASURE(S): Premature luteinization, defined as a progesterone/E2 ratio of >1 on the day of hCG administration. RESULT(S): Fifteen (88%) of the 17 patients in group A and 13 (76%) of the 17 patients in group B demonstrated premature luteinization. In contrast, only 1 (6%) of the 17 patients in group C had a progesterone/E2 ratio of >1 on the day of hCG administration. The mean (+/-SD) E2 level on the day of hCG administration was significantly higher in group C (1.236 +/- 772.7 pg/mL) than in group A (214.02 +/- 104.46 pg/mL) or group B (412.5 +/- 337 pg/mL). CONCLUSION(S): Pituitary desensitization with a GnRH agonist in conjunction with hMG may be of benefit for older infertile women who demonstrate early luteinization in their first evaluation cycle.

The effect of increasing age on the outcome of hysteroscopic endometrial resection for management of dysfunctional uterine bleeding.

STUDY OBJECTIVE: To determine the outcome of hysteroscopic endometrial resection for dysfunctional uterine bleeding according to women's age. DESIGN: Long-term follow-up by telephone interview (Canadian Task Force classification II-2). SETTING: University-affiliated medical center. Patients. One hundred sixty-nine women with abnormal uterine bleeding unresponsive to conservative medical management. INTERVENTION: Hysteroscopic endometrial resection. MEASUREMENTS AND MAIN RESULTS: Questionnaires were completed for 162 (95.9%) patients with mean +/- SD follow-up of 32 +/- 17 months. The frequency of postoperative complications was not related to age. After ablation, the rate of amenorrhea was significantly higher in 31 women age 50 years or older than in younger women (p <0.001), and also in 72 women age 45 to 49 than in 59 age 44 or less (p <0.05). Complete relief of dysmenorrhea was achieved significantly more often in women age 45 to 49 (p <0.005) and 50 or older (p <0.05) than in those age 44 or younger. Dissatisfaction with the outcome of endometrial resection was uncommon, but most frequent among women age 44 or younger (p <0.10). There was no difference in the proportion of women requiring second ablation or hysterectomy in any age group. CONCLUSION: Significantly higher rates of amenorrhea and complete relief of dysmenorrhea after endometrial resection are achieved in older than in younger women.

End-tidal carbon monoxide measurements in women with pregnancy-induced hypertension and preeclampsia.

OBJECTIVE: We sought to compare the end-tidal carbon monoxide breath levels in pregnant women with and without pregnancy-induced hypertension and preeclampsia. STUDY DESIGN: We prospectively performed end-tidal carbon monoxide measurements corrected for ambient carbon monoxide in nonsmoking women during late gestation (>31 weeks). The study group included 22 women with pregnancy-induced hypertension or symptoms of preeclampsia and a control group of 20 normotensive pregnant women. RESULTS: The carbon monoxide measurements corrected for ambient carbon monoxide (mean +/- SD) were significantly lower (P <.01) in the hypertensive group than in the control group (1.17 +/- 0.35 vs 1.70 +/- 0.54 ppm). The study group had a significantly higher number of low (<1.2 ppm) end-tidal carbon monoxide measurements corrected for ambient carbon monoxide (13 [59.1%] vs 1 [5.0%]; P <.001). The end-tidal carbon monoxide measurements corrected for ambient carbon monoxide remained significantly lower in comparison with those found in the control group when the study group was divided into women with pregnancy-induced hypertension only (n = 11) and those with preeclampsia (n = 11) (1.19 +/- 0.37 ppm; P <.01; and 1.15 +/- 0.41 ppm; P <.01; respectively). CONCLUSIONS: Our findings suggest that carbon monoxide formation may be significantly lower in women with pregnancy-induced hypertension and preeclampsia. These data suggest that carbon monoxide could have a contributory role in the apparent paradox of the seemingly protective effect of smoking to decrease the risk of preeclampsia.

Sonographic and clinical characteristics of struma ovarii.

Our objective was to evaluate the preoperative clinical, laboratory, and sonographic characteristics of struma ovarii in comparison to ovarian dermoid cysts. A retrospective review of gynecologic patients operated on for mature cystic teratoma over a 10 year period identified 12 cases of struma ovarii. These cases, combined with 4 additional cases from an earlier report, were the subject of this study. Results were compared to 32 cases of ovarian dermoid cysts. Ovarian struma ovarii occurred in 12 (4.8%) of 251 cases of ovarian dermoid cysts. Most patients were premenopausal, and the mean lesion diameter was 57.3 mm (range, 30-95 mm). Struma ovarii occurred more frequently (68.8%) in the right adnexa and was seen with a normal CA-125 level. Blood flow, assessed by Doppler ultrasonography, was located in the center of the lesion in all cases of struma ovarii. Rare cases were seen with elevated tumor markers and low resistance blood flow. With regard to dermoid cysts, blood flow had a higher resistive index. In addition, no blood flow could be detected from the center of the echoic lesion in dermoid cysts (P < 0.0001). In summary, it is difficult to distinguish between struma ovarii and dermoid cysts on the basis of their sonographic appearance. Nevertheless, Doppler flow may aid in the preoperative diagnosis of struma ovarii. Blood flow signals, detected from the center of the echoic lesion, and low resistance to flow may be more common in struma ovarii.

A new blue light-emitting phototherapy device: a prospective randomized controlled study.

OBJECTIVE: To evaluate the efficacy of a new phototherapy light source with a narrow luminous blue spectrum. The device, made with high-intensity gallium nitride light-emitting diodes (LEDs), was compared with conventional phototherapy at similar light intensities. SETTING: Two university-affiliated community hospitals in Jerusalem. DESIGN: Prospective open randomized study. PARTICIPANTS: Sixty-nine jaundiced, but otherwise healthy, term infants who met the entry criteria for phototherapy set by the American Academy of Pediatrics' Practice Parameter. MAIN OUTCOME MEASURES: The duration of phototherapy and the rate of decrease in total serum bilirubin (TSB) concentration. RESULTS: The mean TSB concentrations at initiation and termination of treatment did not differ between newborns receiving LED and those receiving conventional phototherapy. The duration of phototherapy and the rate of decrease in TSB concentration were not statistically different in the 2 groups. The average rate of decrease in TSB after adjustment by a linear regression analysis for confounding factors was -3.16 micromol/L/h (95% confidence limits -4.81, -1.51) in newborns receiving LED phototherapy compared with -2.19 micromol/L/h (-3.99, -0.40) in those treated with conventional phototherapy (P <.14). No side effects were noted in any of the newborns. CONCLUSIONS: The blue gallium nitride LED device is as effective as conventional phototherapy and is readily accepted by nursing staff. Future LED phototherapy devices can provide much higher irradiance, and thus greater efficacy, and offer a new highly versatile approach to the treatment of jaundice.

Laparoscopy versus laparotomy in the management of adnexal masses during pregnancy.

OBJECTIVE: To compare the outcome of pregnancy after operative laparoscopy or laparotomy for the management of adnexal pathology during pregnancy. DESIGN: Retrospective comparative study. SETTING: University tertiary care referral center for endoscopic surgery. PATIENT(S): Eighty-eight pregnant women who underwent 93 operations for suspected adnexal pathology at our institute. Laparoscopy was performed during the first trimester in 39 patients. The remaining 54 patients underwent laparotomy, 25 during the first trimester and 29 during the second trimester. INTERVENTION(S): Laparoscopy or laparotomy for the management of adnexal masses during pregnancy. MAIN OUTCOME MEASURE(S): Operative and postoperative maternal complications, miscarriage, congenital malformations, and newborn long-term outcome. RESULT(S): No operative or postoperative maternal complications occurred in the pregnant women who underwent laparoscopic surgery. In this group of 39 women, 5 women had a first-trimester miscarriage and 2 newborns had congenital malformations (hypospadias and cleft lip and palate). Two miscarriages occurred in the first-trimester laparotomy group, and 1 congenital malformation (transposition of the great vessels) was diagnosed in the second-trimester laparotomy group. CONCLUSION(S): Laparoscopic gynecologic surgery appears to be safe during pregnancy, although prospective controlled studies and national registries encompassing larger numbers of cases are needed.

A randomized, prospective study of endometrial resection to prevent recurrent endometrial polyps in women with breast cancer receiving tamoxifen.

STUDY OBJECTIVE: To assess the role of endometrial resection in preventing recurrence of tamoxifen-associated endometrial polyps in women with breast cancer. DESIGN: Randomized, prospective study (Canadian Task Force classification I). SETTING: Tertiary university-affiliated medical center. PATIENTS: Twenty consecutive women (age range 43-61 yrs). INTERVENTIONS: Hysteroscopic removal of tamoxifen-associated endometrial polyps with or without simultaneous resection of the endometrium. MEASUREMENTS AND MAIN RESULTS: Patients were randomized to undergo (10 women) or not undergo (10) concomitant endometrial resection. They were followed for at least 18 months (range 18-24 mo), including transvaginal ultrasonography every 6 months and hysteroscopy when endometrial irregularity was noted. The main outcome variable was recurrence of endometrial polyps; occurrence of uterine bleeding was also noted. In women who underwent endometrial resection, only one had a 1 x 1-cm endometrial polyp diagnosed and removed during follow-up. Seven women remained amenorrheic, and three experienced spotting for a few days every month. In the control group, six women had recurrent endometrial polyps requiring hysteroscopic removal (two-tail Fisher's exact test p <0.06). CONCLUSION: Recurrence of endometrial polyps, one of the most common problems in patients with breast cancer receiving long-term treatment with tamoxifen, may be reduced by performing endometrial resection at the time of hysteroscopic removal of polyps. The possible risk of occult endometrial cancer is yet to be determined. (J Am Assoc Gynecol Laparosc 6(3):285-288, 1999)

Laparoscopic detorsion allows sparing of the twisted ischemic adnexa.

STUDY OBJECTIVE: To determine the safety and outcome of laparoscopic detorsion in the management of the twisted ischemic, hemorrhagic adnexa. DESIGN: Retrospective chart review and prospective follow-up (Canadian Task Force classification II-2). SETTING: University-affiliated hospital. PATIENTS: Fifty-eight women with twisted black-bluish ischemic adnexa encountered at laparoscopy. INTERVENTION: Laparoscopic detorsion with adnexal sparing. MEASUREMENTS AND MAIN RESULTS: All patients had a benign immediate postoperative course. Transient temperature elevation occurred in seven women (12.1%). No signs of pelvic or systemic thromboembolism were detected in any patient. Long-term follow-up included transvaginal ultrasound, which revealed follicular development in the previously twisted adnexa in 54 women; normal macroscopic appearance at incidental subsequent surgery in 9; and in vitro fertilization with retrieval of oocytes from the previously twisted side in 4. CONCLUSION: Laparoscopic detorsion of the twisted ischemic, hemorrhagic adnexa is a safe procedure with minimal postoperative morbidity and a potential for the ovary to recuperate fully with preservation of normal function. Laparoscopic adnexa-sparing procedures should be performed in place of traditional salpingo-oophorectomy in women with this disorder who desire future fertility. (J Am Assoc Gynecol Laparosc 6(2):139-143, 1999)
