Abstract
OBJECTIVE To determine whether routine antepartum stretching of the cervix and stripping of the membranes at term would shorten the length of pregnancies, and whether this correlated with cervical status and fetal and maternal parameters. DESIGN A prospective, randomised, controlled study of 293 term gravidas, free of medical complications, divided into two groups: stretching/stripping, and non-stretching/stripping. Digital separation of the fetal membranes from the lower uterine segment, and cervical stretching, were performed during routine vaginal examination of the first group. In the second group, only routine vaginal examination was performed. RESULTS Of 293 patients, 152 underwent a trial of stretching and stripping; 141 served as a control group. The mean interval (hours to delivery after the procedure) was 136 h (S.D. 10), compared to 161 h (S.D. 11) in the control group (P = 0.095; not significant), but with only a trend towards the shorter interval in the first group. When patients were matched according to weeks of gestation and fetal and maternal parameters, only those at 41 weeks' gestation or more had a significant reduction in the interval from the procedure to delivery (mean 91 h (S.D. 8) compared to mean 125 h (S.D. 10) in the control group; P < 0.007). This observation was independent of cervical status and other maternal or fetal parameters. CONCLUSIONS Only patients > or = 41 weeks' gestation benefitted from stretching of the cervix and stripping of the fetal membranes. The effect was not dependent on the cervical status or other maternal and fetal parameters.

Abstract
OBJECTIVE To assess the use of transvaginal ultrasound guidance during operative laparoscopy. STUDY DESIGN Five of 98 consecutive cases of operative laparoscopy for benign-appearing ovarian cysts were complicated by extensive intrapelvic adhesions and a distorted anatomy. Following prolonged dissection, simultaneous transvaginal ultrasonography was used in these cases. RESULTS In all cases we were able to ultrasonographically image and locate the ovarian cyst during the laparoscopic procedure. In four cases this was a significant aid in expediting the procedure and avoiding damage to adjacent pelvic structures. In one case, identification of the ovarian cyst facilitated the decision to resort to laparotomy. CONCLUSION In selected cases, laparoscopic surgeons should be aware of the feasibility and possible benefits of the use of simultaneous intraoperative transvaginal ultrasonography.

Abstract
OBJECTIVE To compare hysteroscopic endometrial resection with transabdominal hysterectomy in women with menorrhagia who failed to respond to conservative treatment. STUDY DESIGN In order to attain correlated samples, only patients with a normal-sized or moderately enlarged uterus were included in the study. RESULTS The operating time, hospital stay and number of women requiring postoperative blood transfusion was significantly lower in the hysteroscopy group. Following hysteroscopy, uterine perforation occurred in three patients, fluid overload in two and dilutional hyponatremia in one. Laparotomy was performed for suspected bowel injury in two cases. The main complication in women undergoing hysterectomy was postoperative fever (36.5%). One case of vesicovaginal fistula was diagnosed seven days postoperatively. CONCLUSION The results indicate that endometrial resection, with its low cost and prompt recovery, offers a promising alternative treatment for women with abnormal uterine bleeding.

Abstract
A case control study of 59 women with subchorionic hematomas compared to 135 normally pregnant. Transvaginal ultrasound was used to image the pregnancy, and identify the site and size of the hematomas. Color flow Doppler was used to calculate velocity indices of the spiral arteries. More spontaneous abortions occurred in women with subchorionic hematomas (SCH). There was general correlation between gestational age, velocity indices, and hematoma size. There were 10 spontaneous abortions in the study group (17%) versus 9 (6.5%) in the controls (P = 0.02). Hematoma size did not affect outcome, but site did. Most hematomas associated with abortion were found in the corpus or fundus of the uterus, not in the supracervical area (P = 0.03). The presence of a hematoma did not affect the frequency of preterm delivery. In conclusion, subchorionic hematomas in early pregnancy are associated with an increased risk of spontaneous abortion. Flow disturbances are seen in the spiral arteries, but these are probably secondary effects. The critical factor is site of hematoma, not volume.

Abstract
A randomized protocol was used to study the effect of intraumbilical prostaglandin F2 alpha (Hembate, Upjohn) and oxytocin injection in women with retained placenta. Prostaglandin F2 alpha, 20 mg, diluted to 20 ml in normal saline solution (10 women, group 1), 30 IU of oxytocin, diluted to 20 ml in normal saline solution (11 women, group 2), or 20 ml of normal saline solution alone (7 women, group 3), were injected into the umbilical vein 1 h after delivery. Nine women (group 4, controls) underwent manual removal of the retained placenta. In group 1, placental expulsion occurred in all patients and the duration of the placental expulsion after prostaglandin F2 alpha injection was 6.8 +/- 1.36 (mean +/- SE) min: in group 2, six placental expulsions occurred after 13.3 +/- 1.97 min (mean +/- SE); and in group 3, no effect was recorded after intraumbilical saline injection. We suggest that intraumbilical vein injection of prostaglandin F2 alpha might be a beneficial, non-surgical method for treating retained placenta. Oxytocin might reduce the incidence of manual lysis of the placenta and achieve partial success.

Abstract
This study was conducted to estimate intrauterine growth of triplet pregnancies from liveborn birth weights. During the years 1975-92, 109 sets of triplets were born at our hospital. Ten sets were excluded because of either major fetal anomalies or fetal death of one or more of the fetuses. The remaining 99 sets of triplets consisted of 297 newborns that were weighted immediately after birth. The mean birth weight was plotted against gestational week. The estimated intrauterine growth of triplets, in contrast to singletons, exhibited neither an acceleration phase during the third trimester, nor a flattening of the growth curve during the last few weeks of the third trimester. The mean birth weight of triplets was slightly below the 10th centile for singletons at 38 weeks' gestation or later. We conclude that the growth of triplet fetuses as estimated from liveborn birth weights is slower than that of singletons. The diagnosis of intrauterine growth retardation in triplet pregnancies should be based on growth curves to be devised for triplet pregnancies.

Abstract
The topical application of recombinant growth factors such as epidermal growth factor, platelet-derived growth factor-BB homodimer (rPDGF-BB), keratinocyte growth factor (rKGF), and neu differentiation factor has resulted in significant acceleration of healing in several animal models of wound repair. In this study, we established highly reproducible and quantifiable full and deep partial thickness porcine burn models in which burns were escharectomized 4 or 5 days postburn and covered with an occlusive dressing to replicate the standard treatment in human burn patients. We then applied these growth factors to assess their efficacy on several parameters of wound repair: extracellular matrix and granulation tissue production, percent reepithelialization, and new epithelial area. In full thickness burns, only rPDGF-BB and the combination of rPDGF-BB and rKGF induced significant changes in burn repair. rPDGF-BB induced marked extracellular matrix and granulation tissue production (P = 0.013) such that the burn defect was filled within several days of escharectomy, but had no effect on new epithelial area or reepithelialization. The combination of rPDGF-BB and rKGF in full thickness burns resulted in a highly significant increase in extracellular matrix and granulation tissue area (P = 0.0009) and a significant increase in new epithelial area (P = 0.007), but had no effect on reepithelialization. In deep partial thickness burns, rKGF induced the most consistent changes. Daily application of rKGF induced a highly significant increase in new epithelial area (P < 0.0001) but induced only a modest increase in reepithelialization (83.7% rKGF-treated versus 70.2% control; P = 0.016) 12 days postburn. rKGF also doubled the number of fully reepithelialized burns (P = 0.02) at 13 days postburn, at least partially because of marked stimulation of both epidermal and follicular proliferation as assessed by proliferating cell nuclear antigen expression. In situ hybridization for KGFR in porcine burns revealed strong expression of KGFR on hair follicles and basal epidermis, confirming direct rKGF action on follicular as well as epidermal keratinocytes. Although the epithelial proliferation induced by rKGF resulted in marked neoepidermal psoriasiform hyperplasia with exaggerated rete ridges and neoepidermal and follicular maturation as assessed by expression of cytokeratin 10, a marker of keratinocyte terminal differentiation was not delayed and appeared to be accelerated in some rKGF-treated burns. Recombinant epidermal growth factor induced a trend toward increased new epithelial area in deep partial thickness burns, but had no effect on reepithelialization. The recombinant neu differentiation factor-alpha 2 isoform had no significant biological effects in either full or deep partial thickness burns.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The reproductive outcome of women with repeated abortions or infertility was assessed following treatment by operative hysteroscopy for an intrauterine septum or adhesions. A prospective follow-up study (mean +/- SD, 21.1 +/- 10.3 months) of 47 patients with an intrauterine septum (36 suffering from infertility and 11 from recurrent abortions) and 36 patients with intrauterine adhesions (24 complaining of infertility and 12 of recurrent abortions) was performed. The pregnancy rate in infertile women following hysteroscopic resection of an intrauterine septum or adhesions was 53 and 48% respectively. The pregnancy wastage in women with recurrent abortions who underwent hysteroscopic resection of an intrauterine septum or adhesions decreased postoperatively from 87.5 to 44.4% and from 86.5 to 42.8% respectively. Our results suggest that hysteroscopic resection of an intrauterine septum or adhesions may benefit patients suffering from infertility or recurrent pregnancy wastage.

Abstract
OBJECTIVE To examine the reproductive outcome after operative hysteroscopic resection of submucous myomas in women for whom no other infertility factor was identified. DESIGN Fifteen infertile women with submucous myomas underwent an intensive workup to exclude other causes of infertility. Operative hysteroscopy for resection of the submucous myomas was performed using a rigid 26 French resectoscope (Karl Storz GmbH & Co., Tuttlingen, Germany). SETTING Academic tertiary referral center. RESULTS The mean +/- SD duration of the procedure was 25.5 +/- 5.6 minutes. No operative or postoperative complications occurred and all patients were discharged within 6 hours. The follow-up period was 12.0 +/- 4.2 months (mean +/- SD). Seven women conceived (pregnancy rate of 47%) and six of them subsequently delivered at term. CONCLUSION The results of this study indicate that operative hysteroscopy achieved a pregnancy rate comparable to myomectomy via laparotomy. These results suggest that operative hysteroscopy is the procedure of choice for the resection of submucous myomas in infertile women.

Abstract
Most menopausal patients with breast cancer receive tamoxifen therapy. In these patients, TVS may show thickened, irregular cystic endometria. For better visualization of these patients' uterine cavities, we performed transvaginal sonohysterography. During vaginal ultrasonography, sterile saline was introduced by transcervical 8 French Foley catheter into the uterine cavity of 20 women who were referred with tamoxifen-associated cystic thickened endometria. In eight women, transvaginal sonohysterography provided the means to diagnose occult, free-floating endometrial polyps, whereas in 12 women, the fluid contrast augmented the diagnosis of an irregular cystic endometrial-myometrial junction. All 20 patients underwent diagnostic hysteroscopy: eight polyps, none of which were malignant, were confirmed and removed by hysteroscopic resection. Of the remaining 12 patients with an irregular endometrial-myometrial junction, endometrial curettage showed no significant pathologic findings. Transvaginal sonohysterography seems to enhance the differentiation between endometrial polyps that should be resected by operative hysteroscopy and an abnormal endometrial-myometrial junction that may benefit from biopsy sampling only.

Abstract
In menopausal patients with breast cancer who receive tamoxifen therapy, transvaginal sonography may show an abnormal endometrium. Our objective was to evaluate the effects of prolonged tamoxifen therapy on endometrial blood flow in postmenopausal patients with breast cancer, and to correlate blood flow characteristics with the sonographic appearance of the endometrium and its pathology. Transvaginal color Doppler ultrasound examinations were performed on 45 postmenopausal women (age range 54-70 years) with breast cancer, who had been treated with tamoxifen for 1-3 years. Twenty women (Group 1) had a thick, irregular, cystic endometrium of > or = 5 mm, and 25 (Group 2) showed a thin endometrium of < 5 mm. The blood flow response was assessed by visualization of arterial waveforms in the endometrial and subendometrial regions with a transvaginal color flow imaging system. Resistance indexes (RI) were calculated for analysis and correlated with endometrial appearance and histology. The mean RI in Group 1 was 0.39 +/- 0.10 (range 0.32-0.54), while the mean RI in Group 2 was 0.79 +/- 0.10 (range 0.54-0.90; p < 0.001). On histology, 12 patients in Group 1 showed atrophic endometria confirmed by hysteroscopy, while in the remaining eight, endometrial polyps were found. In Group 2, all patients had scanty, atrophic endometria. Six of the eight patients with endometrial polyps had an RI of < 0.4 and none had malignant changes. These data suggest that tamoxifen therapy in women with postmenopausal breast cancer induces endometrial, morphological and blood flow changes, mimicking endometrial neoplasia.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A prospective study was carried out on 153 couples with recurrent abortions who desired pregnancy. The object was to determine the incidence of raised luteinizing hormone (LH) levels; to compare the outcome of further pregnancies in habitually aborting women with and without raised circulating LH concentrations; and to assess whether the efficacy of paternal leukocyte immunization is affected in the presence of raised LH concentrations. Of the 153 women with recurrent abortions (> 3) included in this study, 56 (36.6%) had follicular phase serum LH concentrations > 10 mIU/ml. Of the 103 pregnancies that were followed prospectively, 65 (63.1%) resulted in a birth of a live infant. There was no significant relationship between the pregnancy outcome and LH concentrations. Women who underwent immunization with paternal leukocytes had significantly more live births (75.8%) than those who were not immunized (43.6%). However, the live birth rate was lower after paternal leukocyte immunization in the presence of raised LH concentrations or a raised LH/follicle stimulating hormone (FSH) ratio.

Abstract
All cases of combined vaginal-abdominal deliveries at the Department of Obstetrics and Gynecology, Chaim Sheba Medical Center, over an eight-year period (1984-1991) were reviewed. During this period a total of 38,821 deliveries took place. Of 722 (1.9%) twin deliveries, 354 (48.8%) were by cesarean section; 19 were combined deliveries, including 5% of all twins delivered by cesarean section and 2.6% of all twins delivered. High transverse lie and prolapse of the umbilical cord were the main indications for delivery by cesarean section of the second twin. In order to diminish the number of combined deliveries and to increase obstetric skills and experience, a program or protocol for vaginal twin deliveries is indicated.

Abstract
This study was undertaken to report the results of microsurgical lysis of peri-adnexal adhesions and identify the patients who should be offered surgery and those who should be treated by in-vitro fertilization (IVF). In all, 19 women had filmy adhesions and 32 had dense adhesions; 68.4% of women with filmy adhesions conceived compared with 34.4% of women with dense adhesions (P = 0.02). In patients with filmy adhesions, the cumulative pregnancy rate 2 years after operation (47%) is similar to that reported after five cycles of IVF (52%), leading us to conclude that such patients should be offered surgery first. Dense adhesions are best treated by IVF. Lysis of filmy adhesions produces a similar intra-uterine pregnancy rate whether performed by laparotomy (57.9%) or laparoscopy (56.6%). As operative laparoscopy offers the greatest patient comfort, it is the treatment of choice in these patients.

Abstract
In this prospective study we compared transvaginal duplex Doppler ultrasound with two-dimensional imaging for the diagnosis or exclusion of ectopic pregnancies. The study group comprised 76 stable patients with serum beta-human chorionic gonadotropin (hCG) levels > 100 mIU/ml in whom ectopic pregnancy was clinically suspected. Ectopic pregnancies were verified in 42 patients (60%), intrauterine pregnancies (normal and abnormal) in 19 (27%), and possible complete abortions, either intrauterine or extrauterine, in 9 patients (13%). Based on 2-D imaging alone, the appearance of an adnexal mass separated from the ovaries, and a lack of clear intrauterine gestational sac indicated ectopic pregnancy with a sensitivity of 95%. Intrauterine sac-like structures and absence of adnexal masses excluded ectopic pregnancies with a specificity of 89%. High velocity systolic flow, and low impedance diastolic flow which characterizes trophoblastic tissue when detected outside the uterus, had a sensitivity of 48%, while the presence of trophoblastic signals in the uterus or their absence outside the uterus excluded ectopic pregnancies with a specificity of 89%. The positive predictive values were 91% for Doppler and 95% for 2-D imaging, while the negative predictive values were 89% for imaging alone and 44% for Doppler. These data suggest that transvaginal Doppler ultrasound has significant lower sensitivity and negative predictive value and does not provide more useful diagnostic information than 2-D imaging alone for stable patients with suspected ectopic pregnancies.

Abstract
Thermal reactions of proton-bound dimers, (CH3CN)2H (+), (CH3OCH3)2H (+), and (CH3COCH3)2H(+), were studied using a selected ion flow tube. Reactions observed include association, switching, and proton transfer. The association channel was observed only for base molecules that had hydrogen bonding protons such as NH3, CH3NH2, (CH3)2NH, and CH3OH. An association-insertion mechaniSoc was proposed in which the central proton of the symmetrically bound dimers is replaced by a protonated base, for example, NH 4 (+) . These reactions are relatively slow, which demonstrates a central barrier along the potential energy surface. Ether-containing dimers do not demonstrate this insertion reaction, except for diethers, for example, CH3OCH2CH2OCH3, which can form stable bicyclic structures. Dimers such as (HCOOH)2H(+), which possess hydrogen bonding protons in the periphery, undergo switching reactions with ammonia and no insertion.

Abstract
We present a rare case in which therapy of primary ovarian pregnancy, using laparoscopic laser surgery (videolaseroscopy), was successfully performed without the need of laparotomy. Because operative laparoscopy has the benefits of reduced morbidity, reduced hospitalization and rapid recovery, and because it has the advantage of reducing postoperative adhesions as compared to laparotomy, it is the preferable technique for treatment of ovarian gestation after a laparoscopic diagnosis, especially for a woman who desires to preserve her fertility potential.

Abstract
A high rate of ovarian multifollicular development and resulting multiple pregnancy remains the main problem of ovulation induction with human menopausal gonadotropins. The aim of this study was to examine a possible correlation between the number and size of ovarian follicles at the time of human chorionic gonadotropin (hCG) administration and to find parameters that can predict the occurrence of multiple pregnancies. Sixty-eight intrauterine pregnancies, 53 singletons and 15 multiple pregnancies in 51 patients, were included in this study. We found no significant difference in the mean estradiol levels, the total number of pre-ovulatory follicles, or the mean number of large, intermediate or small follicles at the time of hCG administration between women who had singleton pregnancies and those with multiple pregnancies. Our study demonstrates that estradiol levels and ovarian ultrasonography do not provide criteria for the prediction of the occurrence of multiple pregnancies in menotropin cycles.

Abstract
OBJECTIVE To determine whether complete failure of fertilization of oocytes in couples with mechanical infertility during the first IVF cycle indicates a poor prognosis for subsequent IVF cycles. DESIGN A retrospective study of 172 cycles of IVF in 50 couples with mechanical infertility and complete failure of fertilization during their first IVF trial. SETTING In vitro fertilization unit of the Sheba Medical Center. PATIENTS Fifty couples undergoing one to eight cycles of IVF for mechanical infertility. MAIN OUTCOME MEASURE(S) Fertilization rate of retrieved oocytes and pregnancy rate. RESULTS Of the initial 50 couples, 44 underwent additional IVF cycles, and 43 (97.7%) achieved fertilization during the second or third cycle. Twenty-four patients conceived during the study period as a result of IVF. CONCLUSIONS Complete failure of fertilization in couples with mechanical infertility does not necessarily persist during subsequent IVF cycles. Therefore, at least two more IVF cycles should be attempted before reverting to other therapeutic options. Complete failure of fertilization during the first cycle of IVF in couples with mechanical infertility is accompanied by a good prognosis for subsequent cycles.

Abstract
The possible relationship between the season of conception after ovulation induction and high-order multifetal pregnancies, was investigated. From 1975 to 1989, 111 high-order multiple births after ovulation induction were recorded at the Chaim Sheba Medical Center. This group was compared with 142 singleton pregnancies that resulted from induction of ovulation during 1989. Composite monthly cohorts of high-order multifetal pregnancies were constructed for each month of the year, and the probability of such pregnancies was estimated. The period of ovulation induction and the day of presumed conception were noted. A statistically-significant increase in the probability of high-order and singleton conceptions occurred during the winter. Our observation indicates a seasonal pattern in high order and singleton conceptions after ovulation induction.

Abstract
Between January 1984 and August 1991, 511 cases of extrauterine pregnancies were diagnosed by laparoscopy in our department. In 374 cases salpingectomy was performed: 184 by explorative laparotomy, and 190 by operative laparoscopy. Patients were scheduled for salpingectomy if one or more of the following criteria were fulfilled: (i) a ruptured tube which was surgically unsuitable for conservation; (ii) no interest in future fertility; (iii) tubes with ectopic gestation previously operated on; (iv) a previous tubal pregnancy on the same side, which was treated expectantly. Salpingectomy was performed via operative laparoscopy with bipolar diathermy forceps and laparoscopic scissors. Pregnancy rates, i.e. intra-uterine and repeat extra-uterine, were evaluated. The reproductive performance following salpingectomy did not differ significantly, whether by laparotomy or laparoscopy: the intra-uterine pregnancy rate was 78 and 64%, respectively and the repeat ectopic pregnancy rate was 12 and 6%, respectively. Salpingectomy via laparoscopy can be performed safely with a low incidence of complications, with subsequent reproductive performance comparable to laparotomy.

Abstract
Our objective was to apply a new surgical technique to ovarian cystectomy combining the advantages of laparoscopy with the benefits of microsurgical principles, in an attempt to simplify the surgical laparoscopic procedure and reduce postoperative adhesion formation. Between May 1991 and March 1992, extracorporal ovarian cystectomy was performed in 27 patients who presented with persistent ovarian cysts at the department of gynecology of a large teaching hospital that receives primary referrals from public health care patients. Patients were referred with the diagnosis of a persistent ovarian cyst. Diagnosis was confirmed by pelvic bimanual examination, and transvaginal ultrasound. Cases where malignancy was suspected due to the presence of ascites, semi-solid or solid masses, demonstration of papillations within the ovarian cyst on ultrasound, or elevated CA-125 levels (unless endometriosis was suspected) were excluded from the study group. At laparoscopy, after inspection of the abdominal cavity the cyst was aspirated. The ovary was then extracted through a 2- to 3-cm lower-abdominal incision, cystectomy was meticulously performed according to microsurgical principles, and the repaired ovary was then returned into the abdominal cavity. Extracorporal cystectomy was successfully performed in 26 of 27 cases. The mean duration of the operative procedure was 55 min. The postoperative course was uneventful. Mean postoperative hospitalization time was 22.4 h. Over a follow-up period of up to 15 months, ovarian folliculogenesis was confirmed ultrasonographically. In the first 2 patients to undergo second-look laparoscopy, no adhesions were seen.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVE Our purpose was to report transient complications associated with operative hysteroscopy with glycine used as the distending medium. STUDY DESIGN All the operative hysteroscopies performed over a 6-month period by a single operator were examined. The blood oxygenation and end-tidal carbon dioxide concentrations were monitored in all cases with a pulse oximeter and a capnograph. Blood samples were obtained during the operation and over the next day to determine coagulation functions, sodium levels, and a complete blood cell count. RESULTS Oxygen desaturation accompanied by a simultaneous increase in blood carbon dioxide levels occurred in six of the 46 patients. In addition, four of these patients were found to have a significant blood coagulopathy. Hyponatremia was observed in only two of the latter patients. CONCLUSION Patients undergoing transcervical resection of the endometrium or submucous myomectomy must be closely monitored because disturbances in oxygenation and coagulation functions are not rare. The possibility of avoiding these complications by careful control of intrauterine pressure and the absorption of glycine should be further examined.
