Background: Several organs may be damaged by strangulation by hair or strings that cause ischemia and necrosis. There have been sporadic case reports of such events. Injuries to the hands, feet, and fingers, as well as penile(1-5) and clitoral injuries(6-8) have been reported., Cases: Three cases of labia minor strangulation by hair are described. A review of the relevant literature is included., Conclusions: Pediatricians, gynecologists, and family physicians must be aware of labial tourniquet syndrome. If the diagnosis is missed or remains without immediate attention, the hair or string may cause necrosis and the resulting amputation of the vital body part.

Purpose: Description and evaluation of the sonographic changes at the site of the myomectomy and follow-up of the healing process., Methods: Twelve patients with intramural fibroids underwent myomectomy. Pre- and postoperative ultrasound examinations included measurements of uterine volume and the largest diameters of the largest fibroid and the myomectomy scar., Results: The mean uterine preoperative volume was 773 cm(3) (range 271-1,343) (SD 285). It decreased postoperatively to 318 cm(3) (range 98-756) (SD 192) and 185 cm(3) (range 78-420) (SD 96) in the immediate and late scans, respectively. The mean size of the largest diameter of the largest fibroid was 10 cm (range 7-15) (SD 2.3). The largest diameter of the immediate postoperative myomectomy site was 4.5 cm (range 2.2-8) (SD 1.8) decreasing later to 2.4 cm (range 0-6) (SD 1.6)., Conclusion: The postoperative sonographic findings following myomectomy demonstrates a solid finding that may mistakenly be interpreted as the remaining fibroid that shrinks gradually. The finding is probably the result of changes in hyperplastic myometrial tissue, focal small hematomata and suture material.

Most gynecologists lack the unique skills required for communication with female adolescent patients and with their parents. Years of clinical experience are required to develop communication skills that would facilitate the confidence of the young patient already during the first visit. Simulation-based medical education at the Israel Center for Medical Simulation (MSR) has become a powerful force in quality-care training for healthcare providers using empirical educational modalities, enabling controlled proactive experiential exposure to both regular and complex scenarios. Among the various MSR programs, for various medical sectors, training programs have been developed to improve the skills of physicians communicating with adolescents, including primary care physicians and school doctors. This paper describes the first reported simulated patient-based MSR training program for gynecologists in communication with adolescents who present with common complaints encountered in gynecology clinics. Twenty gynecologists participated in eight individual simulated scenarios conducted at simulated physicians' offices, equipped with audio-visual recording cameras and one-way mirrors for observation. Three physicians experienced in debriefing and in facilitating group discussions led the debriefing sessions, using the video recording of the simulated scenario following the simulation exercises. These discussions focused on communication techniques when facing adolescent patients with or without their parents, hidden agendas disclosed by using systematic physical and psychosocial reviews, the emotional load often associated with clinical problems, and the non-judgmental and supportive approach to adolescent patients. The clear recommendation that emerged from the high satisfaction of the program participants was to expand simulated patient-based programs for gynecologists and to include it as an integrated part of the training curriculum in pediatric and adolescent gynecology.

Congenital distal vaginal obstruction is a rare condition, usually asymptomatic until menarche, thus often diagnosed only during puberty. Hydrometrocolpos is caused by such an obstruction, only when reasonable amounts of fluid are secreted from the mucosal lining of the genital tract. This presentation may be symptomatic and already diagnosed early in life, even during the perinatal period. There are various causes of congenital vaginal obstruction, and according to their etiology, surgical procedures may be either simple or more complicated. Timing of the surgical procedure for opening the obstruction is a dilemma. We suggest postponing the definite procedure to the menarche, when hematocolpos (accumulation of blood in the vagina) will develop, but before the further development of hematometra (accumulation of blood in the uterine cavity). This will cause stretching of the obstructed segment, will enable correct diagnosis, facilitate the procedure, and eventually minimize the complications. However, if the vaginal obstruction in neonates or in childhood is symptomatic, as in the described case, aspiration of the fluid and temporary release of the symptoms should be the optimal choice, followed by a final surgical correction latter in life.

Oral contraceptive pills are conventionally prescribed in a manner that causes monthly withdrawal uterine bleeding (lunar month). The reasons for this are historical without an inherent medical need. According to our literature search, there are patients' demands for less frequent menstrual cycles. We have learned from patients who were given the pill continuously for long periods due to medical or social indications that continuous administration of the contraceptive pill is feasible and safe. In the current review, the authors have searched the literature regarding extended cycle oral contraception for periods of time up to one year. This way of administration of the pill is not compromising the efficacy of pregnancy prevention, nor is it detrimental in terms of cardiovascular and hemostatic complications or endometrial malignancy. It is known that there is a slightly increased risk of breast cancer in users of oral contraceptives up to 10 years, regardless of the mode of administration. From a few studies of hormone replacement therapy in postmenopausal women, there is concern that continuous treatment may be deleterious, while sequential is not. Extended cycle contraceptive treatment has a few side effects, mainly increased breakthrough bleeding but decreased withdrawal bleeding. Other side effects were less prevalent than in conventional administration.

Background: Most cases of ovarian edema are thought to result from intermittent ovarian/adnexal torsion. This study describes how, in some cases, this etiology was ruled out even though the edema was unexplained., Study Objective: To evaluate the association between ovarian edema and hemorrhagic corpus luteum., Setting: Department of gynecology in an urban medical center., Participants: Five patients admitted to the department of gynecology with a sonographic diagnosis of ovarian edema of unexplained etiology., Results: Laparoscopy performed on three of five patients in whom a diagnosis of unexplained ovarian edema revealed hemorrhagic corpus luteum and ovarian edema. The remaining two patients displayed typical sonographic imaging of hemorrhagic corpus luteum and ovarian edema and they were managed expectantly. The affected ovaries were between 4.8 and 10 times larger than the unaffected ovaries. During follow-up, the affected ovaries returned to their normal size and appearance., Conclusions: Hemorrhagic corpus luteum can cause ovarian edema without interrupting the blood flow supply. The outcome of expectant management without any surgical intervention is the gradual disappearance of the ovarian edema in these patients and the return of ovaries to a normal sonographic appearance.

Hydrosalpinx is one of the predisposing factors of adnexal torsion. However, because the incidence of hydrosalpinx in adolescent virgin patients is very rare, it may cause diagnostic dilemma, leading sometimes to suboptimal treatment. We present the case of an 18-yr-old female, not sexually active, presenting with acute lower right abdominal pain. The working diagnosis was of a simple ovarian cyst, so aspiration was performed. Abdominal symptoms reoccurred and sonography revealed a large hemorrhagic cystic mass adjacent to an edematous right ovary. The patient was referred to immediate laparoscopy due to suspected right adnexal torsion. On laparoscopy, the right adnexa was twisted three times causing an edematous ovary with a hematosalpinx. Detorsion was performed. Five weeks later, transabdominal ultrasound reviled normal bilateral ovaries and the hematosalpinx disappeared. In conclusion, hydrosalpinx, although very rare in adolescence, must be considered in the differential diagnosis. Aspiration in such cases is not the treatment of choice and moreover, it may cause complications.

Study Objective: To explore the effect of young age on the outcome of teenage pregnancies by studying teenage deliveries in our unique population., Design, Setting, and Participants: Retrospective chart review of teenage gravidas (age 19 and younger), who had delivered in our hospital., Outcome Measures: Mode of delivery, gestational age at delivery, newborn's weight and Apgar scores and maternal and neonatal complications., Results: We recruited 565 teenage delivery cases from the hospital's computerized database. Mean maternal age was 18 (14-19). Most (96%) were married. Fifty-one percent were Jewish and 44% were Muslim. Most of the girls were nulligravidas. Mean gestational age at delivery was 39 weeks (33-44 weeks). A normal vaginal delivery ensued in 72.7%, while 9% had a cesarean section and 17.4% instrumental deliveries (compared to 85.75%, 10% and 4.25% in our adult population, respectively) and 1% underwent vaginal breech delivery. Mean birth weight was 3108 g (1450-4980 g). Apgar score of 9 at 5 minutes was recorded in 97.8% of the newborns. Prenatal care included a mean of 6 prenatal visits with a range of 1-18. The main complication was anemia; 41% had hemoglobin levels of less than 11 g/dL. The rate of other complications was low., Conclusions: In our homogenous group of teenagers, there was a similar complication rate as in the adult population. The only significant complication was anemia (less than 11 g/dL). There was a higher rate of instrumental deliveries and the cesarean delivery rate was slightly lower than in our adult population. Teenage pregnancy should not be considered as a high-risk situation as long as it is planned and followed with the normal routines of prenatal care.

Purpose: This study was conducted to assess the combination of endometrial thickness, as measured by transvaginal sonography, and time since menopause, in predicting the presence of endometrial cancer in women with postmenopausal bleeding., Methods: The study group consisted of 95 women with postmenopausal bleeding who underwent sonographic measurement of endometrial thickness followed by endometrial biopsy. No patient had ever received hormone replacement therapy., Results: The mean endometrial thickness was significantly lower in the absence of endometrial carcinoma (6.9 +/- 4.3 mm) than in its presence (13.5 +/- 7.7 mm) (p < 0.005). The incidence of endometrial carcinoma increased with increases in endometrial thickness and the number of years since menopause. No patient had carcinoma when the endometrium was less than 5 mm thick, but 18.5% did when the thickness exceeded 9 mm. The incidence of cancer was 2.6% in women who had undergone menopause less than 5 years earlier but was 21.4% in women who had undergone menopause more than 15 years prior. Multiple logistic regression analysis showed that time since menopause and endometrial thickness were statistically significant predictors of endometrial carcinoma., Conclusions: Time since menopause and endometrial thickness together define cutoff points for the diagnostic biopsy of tissue samples for endometrial carcinoma; that is, within a particular time interval, sampling should not be performed if the thickness is below a given value. When using cutoff points of 6 mm of endometrial thickness for women experiencing menopause 5-15 years prior and 5 mm in those going through menopause 15 or more years prior, approximately 60% of invasive procedures may be avoided. In addition, models derived by multiple logistic regression can be used to calculate a patient's risk of cancer based on her age and endometrial thickness., (Copyright 2004 Wiley Periodicals, Inc.)

The purpose of this review article is to evaluate the current method of sonographic measurement of ovarian volume as a means of diagnosing ovarian tumors in postmenopausal women, in whom an ovarian volume greater than 10 ml is generally considered abnormal. After reviewing the general medical literature, we propose a nomogram of ovarian volume that may be used to determine whether an ovary is abnormal. Furthermore, on the basis of our previous results, we recommend that a cutoff point for ovarian volume that is adjusted to patient age be used to determine whether an ovary is abnormal. We recommend the use of such nomograms in routine clinical practice to assist physicians in identifying abnormality of the ovaries during sonographic examination., (Copyright 2004 Wiley Periodicals, Inc.)

Background: The possible problems of an adolescent breast include a large spectrum of phenomena such as changes which may cause aesthetic problems, infectious diseases and in rare cases, malignant tumors. Young adolescents and their mothers tend to consult with a gynecologist usually due to developmental abnormalities of the growing breast such as asymmetry of the breast, agenesis or hypoplasia of one breast. Cysts and tumors are usually worrisome and warrant attention and precise diagnosis., Purpose: The aim of this paper is to review the recent studies and data concerning breast diseases in adolescents and to summarize by presenting symptoms, diagnostic procedures and the most up-to-date treatment modalities., Method: A comprehensive and updated literature review., Results and Conclusions: A large variety of abnormal phenomena in the breast during adolescence have been described. Abnormal breast development in adolescents may present themselves as an aesthetic problem only, but other symptoms such as breast tumors or cysts may arouse suspicion of malignancy of the breast. These findings may be the initiative for the first clinical visit to a gynecologist, initiated by the patient herself or by her parent. Malignancy of the breast in adolescence is very rare, especially when there are no risk factors such as family history or previous X-ray radiation to the breast region. In any case, detailed medical history should be recorded and meticulous physical examination performed in order to rule out any breast pathology that may necessitate prompt treatment. Usually, breast problems in adolescents are benign disorders and only require follow-up without additional treatment. In any aesthetic problem or developmental abnormality, surgery should be postponed until the breast has completed the adolescent stage.

Weight bearing physical activity plays an important role in bone development. This is particularly important in children and adolescents since bone mineral density reaches about 90% of its peak by the end of the second decade, and because about one quarter of adult bone is accumulated during the two years surrounding the peak bone growth velocity. Recent studies suggested that the exercise-induced increase in bone mineralization is maturity dependent, and that there is a "window of opportunity" and a critical period for bone response to weight bearing exercise during early puberty and premenarchal years. This supports the idea that increase in physical activity during childhood and adolescence can prevent bone disorders (like osteoporosis) later in life. In contrast, strenuous physical activity may affect the female reproductive system and lead to "athletic amenorrhea". The prevalence of "athletic amenorrhea" is 4-20 times higher than the general population. As a consequence, bone demineralization may develop with increased risk of skeletal fragility, fractures, vertebral instability, and curvature. Menstrual abnormalities in the female athlete result from hypothalamic suppression of the spontaneous pulsatile secretion of gonadotropin releasing hormone. Recent studies suggested that reduced energy availability (increased energy expenditure with inadequate caloric intake) is the main cause of the central suppression of the hypothalamic pituitary-gonadal axis. Therefore, effort should be made to optimize the nutritional state of female athletes, and if not successful, to reduce the training load in order to prevent menstrual abnormalities, and deleterious bone effects in particular during the critical period of rapid bone growth.

Study Objective: To assess obstetric performance and fetal outcomes after laparoscopy or laparotomy performed during pregnancy., Design: Nationwide, multicenter, retrospective chart review (Canadian Task Force classification II-2)., Setting: Seventeen hospitals throughout Israel: 12 university or university-affiliated hospitals and 5 general hospitals., Patients: Three hundred eighty-nine pregnant women., Intervention: Laparoscopy or laparotomy for various indications., Measurements and Main Results: Of 192 laparoscopies performed, 141 were during the first, 46 during the second, and 5 during the third trimester; respective figures for 197 laparotomies were 63, 110, and 24. No intraoperative complications were reported for either procedure. Six and 25 women had complications after laparoscopy and laparotomy, respectively. There was no significant difference in abortion rates between groups. Mean gestational age at delivery and mean birthweight were comparable between groups. No significant difference was found in frequency of fetal anomalies between groups or when compared with the Israel register of anomalies., Conclusion: Operative laparoscopy seems to be as safe as laparotomy in pregnancy.

The incidence of intrauterine device perforation is 0.87 per 1000 insertions. An intrauterine device (IUD) may perforate through the uterine wall into the pelvic or abdominal cavity or into adjacent organs. The accepted treatment for displaced IUDs is surgical removal because of the putative risk of adhesion formation or of damage to the intestine or urinary bladder. The purpose of this article is to present three cases of IUD perforation where surgical removal may not have been necessary. In all three cases, the IUD was removed by laparoscopy. No adhesions were found in any of the patients. Criteria for the surgical removal of a displaced IUD, as a result of uterine perforation, should be re-evaluated. Whilst surgical procedures to remove a misplaced IUD must be performed on symptomatic patients, asymptomatic patients, under certain circumstances, may benefit from conservative management.

Background: Endometrial polyps are the most common endometrial pathology described in association with postmenopausal tamoxifen exposure. Up to 3% of these polyps may show malignant changes. However, to the authors' knowledge no one has described any risk factor for the development of this pathology in postmenopausal patients with breast carcinoma treated with tamoxifen. OBJECTIVE. The objective of this study was to evaluate whether risk factors can be identified for the development of endometrial polyps in postmenopausal patients with breast carcinoma treated with tamoxifen., Methods: The authors reviewed the medical records of 54 postmenopausal patients with breast carcinoma in whom endometrial polyps were resected by hysteroscopy after at least 6 months of tamoxifen treatment (Group I). Demographic characteristics, health habits, risk factors for endometrial carcinoma, and clinical factors related to the primary breast disease were examined. The results were compared with those obtained from 210 similar patients in whom hysteroscopy did not reveal any endometrial pathology (Group II)., Results: Age at menopause was significantly older, duration of breast disease was significantly longer, and body weight was significantly heavier among Group I patients compared with Group II patients (P = 0.0162, P = 0.0026, and P = 0.0364, respectively). Endometrial thickness, measured by transvaginal ultrasonography, was significantly thicker in Group I patients (16.3 +/- 7.2 mm) compared with that detected in Group II patients (11.8 +/- 6.3; P = 0.0001)., Conclusions: Various factors, such as older age at menopause, longer duration of breast disease, heavier weight, and thicker endometrium may contribute to the prediction of increased risk of development of endometrial polyps in postmenopausal patients with breast carcinoma treated with tamoxifen., (Copyright 2001 American Cancer Society.)

The aim of this study was to describe the ultrasonographic and Doppler flow attributes of granulosa cell tumors (GCT) of the ovary and to compare these attributes to those of epithelial tumors of the ovary. Among 13,475 gynecological patients who were scanned in our ultrasound unit between 1992 and 1996, seven patients had GCT. The final diagnosis was confirmed, postoperatively, by pathologic examination and by applying the WHO classification. The ultrasonographic findings of the GCT patients were compared to those recorded in a second group of 29 patients who had been diagnosed with epithelial tumor of the ovary. The sonographic appearance of GCT of the ovary was semi-solid and the endometrium was thick in six of the seven patients. Doppler flow studies of vessels within or in the contour of the lesions showed the resistive index (RI) to be 0.448 +/- 0.018. The epithelial tumors had a similar appearance and flow pattern except for the presence of ascites in one-third of the patients. Ultrasound scanning, including color Doppler flow, did not contribute data that could assist in differentiating between GCT and epithelial tumors of the ovary.

Clinical data indicate that tamoxifen (TAM) therapy may cause an increased risk of endometrial pathology in postmenopausal but not in premenopausal women. Molecular mechanisms of the uterotrophic activity of TAM have not been clearly established nor its relevance to apoptosis in endometrial cells. The present study was implemented to evaluate the apoptotic effect of TAM on primary endometrial cell cultures in the presence or absence of steroid hormones (SHs). A total of 14 primary endometrial cell cultures were established and maintained both with and without SHs. Cell cultures were treated for 24 h with either 20 microM TAM or 10 nM estradiol. Apoptotic cells presented in a pre-G1 peak and the expression of bcl-2 were studied using flow cytometry. All endometrial cell cultures maintained in a SH-containing environment, except one, responded to TAM by a significant increase (P = 0.03) in the pre-G1 cell fraction, indicating a proapoptotic effect. A significant (P = 0.03) reduction in the pre-G1 peak equivalent to an antiapoptotic response was observed in 6 of 13 cell cultures maintained in a SH-deficient environment. In 4 of 10 cell cultures evaluated in both media, the pre-G1 population was medium dependent. In 8 of 10 cultures evaluated for Bcl2 levels, no trend was found in either media, but a dependency on SH content was observed. Comparison between effects of TAM and estradiol demonstrated identical trends, regardless of the menstrual phase or SH content in cell environments. These results suggest that TAM acts as an estrogen agonist on endometrial tissue in both environments. We conclude that TAM modulates apoptotic pathways in primary endometrial cell cultures. The SH content in the cell environment influences the apoptotic effect of TAM and determines the propensity for a cell to undergo apoptosis or, on the contrary, to resist apoptotic death in response to TAM treatment. This is in concordance with the observed clinical risk of endometrial pathologies in postmenopausal versus premenopausal women.

Background: External cephalic version is attempted prior to the onset of labor. Women who present in labor with footling breech presentation are usually delivered by cesarean section. We present our experience of external version in women in labor., Material and Methods: External cephalic version was attempted in thirteen patients in labor with footling breech presentation with the breech out of the pelvis., Results: The procedure was successful in twelve of the thirteen patients. Ten of them delivered vaginally. There were no maternal or neonatal complications., Conclusions: It may be reasonable to attempt external cephalic version in patients in labor prior to performing a cesarean section.

Objective: To assess whether there is a decrease in endometrial thickness following discontinuation of tamoxifen treatment as measured by ultrasound., Design: Prospective study., Setting: Department of Obstetrics and Gynaecology, Sapir Medical Centre, Kfar-Saba, Israel., Population: Fifty-eight postmenopausal women with breast cancer who were treated with tamoxifen., Methods: Transvaginal ultrasonographic measurements of endometrial thickness., Main Outcome Measures: Evaluation of the changes of endometrial thickness and the frequency the endometrium reached a thickness of < or = 5 mm at different time intervals after stopping tamoxifen treatment., Results: There was a significant decrease in median thickness of the endometrium, within six months after stopping tamoxifen, from 7.75 mm measured at the last ultrasonographic study performed before tamoxifen discontinuation down to 5.2 mm (P = 0.002). There were no further reductions in endometrial thickness, and it remained constantly low in subsequent ultrasonographic studies which were performed at various times up to 30 months following the discontinuation of tamoxifen treatment. While taking tamoxifen, only 25-9% of the women had an endometrial thickness of < or = 5 mm. This proportion doubled in their first six months after stopping., Conclusions: Median thickness of endometrial thickness significantly reduced within six months following tamoxifen discontinuation, and remained constantly low thereafter. This finding may support use of ultrasonographic imaging for the measurement of tamoxifen's effect on the endometrium of postmenopausal breast cancer patients.

Objective: To determine the effects of the changes in fetal renal pelvis dilatation on post-natal diagnosis and outcome., Methods: Prenatal sonographic fetal renal anteroposterior diameters of > or = 4 mm in the second trimester, which persisted to > or = 7 mm in the third trimester, were the inclusion criteria. Fifty-six fetuses and 73 renal units with normal karotypes and a solitary sonographic finding of renal pyelectasis, which met the inclusion criteria, were followed, post-natally, until the age of 30 months. The neonates were categorized into three groups, according to their final diagnosis: No hydronephrosis, pelvi-ureteric junction obstruction and hydronephrosis from other causes. The neonates were also categorized according to their outcome: no treatment, follow-up only and surgical treatment., Results: In 17 neonates (30.4%), and 19 renal units, the diagnosis of hydronephrosis was excluded post-natally. In 39 neonates (69.6%), and 54 renal units, an urinary tract pathology was confirmed. The dynamics of pyelectasis in the second and third trimesters of pregnancy differed significantly among the neonates when categorized according to the final diagnosis (P < 0.05), or according to outcome (P < 0.05)., Conclusion: It is possible to predict, and distinguish between, long-term conservative and surgical treatments of renal pelvis dilatation in the third trimester of pregnancy.

We present a case of a lipomeningocele in a newborn. Prenatal sonography revealed dysraphia and a 3.8 x 4.3 cm, semisolid, echogenic mass that was continuous with the sacral area and bulged posteriorly under the skin. The mass was diagnosed after birth as a lipomeningocele based on the results of MRI. This diagnosis was confirmed histologically., (Copyright 2000 John Wiley & Sons, Inc.)

Background: A new mutation, I1307K, recently was reported in the adenomatous polyposis coli (APC) gene. This mutation was found to be predominant in Ashkenazi Jews, creating a hypermutable area and predisposing the development of carcinoma. The objective of the current study was to estimate the prevalence of this mutation in several of the ethnic groups that comprise the Israeli population and to elucidate the clinical features of the mutation carriers with colorectal carcinoma (CRC)., Methods: A total of 111 consecutive CRC patients were evaluated and their medical history and clinical data recorded. The general population (298 Ashkenazim and 189 Yemenites) also was tested for the presence of this mutation. Mutation screening was performed using both the polymerase chain reaction-based amplification refractory mutation system and a commercial APC kit., Results: Of the total of 111 CRC patients, 15 (13.5%) carried the I1307K mutation and 26 of 487 subjects from the general population (5.3%) carried the I1307K mutation (P = 0.004). Among the 71 Ashkenazi CRC patients there were 12 carriers (16.9%) whereas 17 of the 298 Ashkenazi Jewish general population (5.7%) carried the mutation (P = 0.004). Of the 4 CRC patients of Yemenite origin, 3 carried the mutation and 9 carriers were found among 189 subjects in the general Yemenite population (4.7%) (P = 0.0007). None of the 34 Sepharadic or 2 Arab CRC patients carried the APC I1307K allele. Late age at diagnosis (64.6 years +/- 10.0, which is similar to that of the noncarriers), mostly right-sided tumors, and moderate to good differentiation constituted the phenotype of the mutation carriers., Conclusions: The authors believe the findings of the current study broaden the known spectrum of ethnic groups in which the APC I1307K mutation is prevalent. The phenotype of the mutation carrier CRC patients does not conform to the expected familial pattern of germline mutations. The phenotype and the differential incidence rate of CRC among APC I1307K carriers of various ethnic groups suggest low penetrance., (Copyright 2000 American Cancer Society.)

Coma in pregnancy and labor is a rare and complicated situation. One of the causes is severe head trauma, which requires neurosurgical consultation and possibly urgent transfer to a neurosurgical unit. This should follow stabilization, confirmation of fetal viability, and cesarean section when indicated. A 38-year-old primigravida at term and in labor, with severe head injury from a vehicular accident is reported. Emergency cesarean section was performed for severe fetal distress during resuscitation. Fetal distress in a comatose parturient with severe head injury may require a short delay in referral to a tertiary trauma center to allow for an emergency cesarean section.

Objective: To evaluate the diagnostic accuracy of preoperative transvaginal sonography (TVS) in the detection of deep myometrial invasion in endometrial cancer cases classified by the grade of disease, and in comparison to frozen section analysis in grade 1 cases., Methods: In a prospective study, 91 patients with confirmed endometrial carcinoma underwent preoperative TVS for evaluation of myoinvasion. Sonographic results were categorized as superficial (less than or equal to 1/2 myometrial depth) and deep invasion (greater than 1/2 myometrial depth). TAH-BSO followed by retroperitoneal lymph node sampling were performed in all patients with grade 2-3 tumors. In patients with grade 1 disease, the surgical specimen was intraoperatively evaluated by frozen section, and lymph node sampling was carried out if deep invasion was determined. The preoperative sonographic findings and the frozen section results were compared to the final histopathology report of myoinvasion., Results: In 77 of the 91 (84.6%) patients, the sonographic assessment of the depth of myoinvasion was in accord with the final histopathologic findings. TVS demonstrated a sensitivity of 87.8% and a specificity of 82.7% in detecting deep invasion in the entire study group (grade 1-3), with positive and negative predictive values (PPV, NPV) of 74.3% and 92.3%, respectively. TVS in grade 1 cases (n=47) showed a sensitivity of 77.7%, a specificity of 79%, PPV of 46.6% and NPV of 93.7%. TVS in cases with grade 2-3 tumors (n=44) showed a sensitivity of 90%, specificity of 91.6%, PPV of 90% and NPV of 91.6%. Thus, the accuracy of TVS in grade 2-3 cases was superior to that achieved in grade 1 cases (91% vs 78.7%; p=.002). The myometrial invasion was assessed by frozen section in 41 out of 47 patients with grade 1 disease and demonstrated a sensitivity of 85.7%, a specificity of 100%, PPV of 100% and NPV of 97.1%. The specificity (100%) and accuracy (97.5%) of the frozen section were found to be superior compared to that of the TVS (79% and 78.7%) in detecting deep invasion in grade 1 cases (p=.008, p=.005, respectively). No statistically significant difference was found between the sensitivity of either technique., Conclusions: TVS appeared to be a more accurate method for preoperative assessment of myoinvasion in grade 2-3 endometrial cancer patients compared to grade 1 patients. In grade 1 cases, this method achieved lower accuracy in detecting deep invasion compared to the frozen section analysis. Based on these data, the value of preoperative TVS results as the sole criterion in the decision to perform extensive surgical procedures in grade 1 endometrial cancer is questionable and warrants further evaluation.

Purpose of Investigation: 1) To assess whether endometrial specimens obtained from removed uteri might show an increase in endometrial pathologies which had been previously diagnosed by hysteroscopy in postmenopausal breast cancer tamoxifen-treated patients. 2) To assess whether hysteroscopy is an efficient method of detecting endometrial pathologies in such patients., Methods: The findings of two consecutive pathological evaluations in 18 postmenopausal breast cancer tamoxifen-treated patients, performed 11.2+/-11.2 months apart, were compared. The first specimen was collected by hysteroscopy and the second was obtained following hysterectomy., Results: The most significant changes observed were three new cancers diagnosed at hysterectomy, one of which was poorly-differentiated. In the first (hysteroscopy) samplings, one patient had atrophic endometrium, a second patient had endometrial proliferation and a third patient had a benign endometrial polyp. Overall, 55.6% of the study patients had various endometrial pathologies in the first sampling, while 83.3% had endometrial pathologies in the second sampling. However, this difference was not statistically significant., Conclusion: 1) Endometrial histologic evaluations, performed on removed uteri 11.2+/-11.2 months following previous endometrial samplings of postmenopausal breast cancer tamoxifen-treated patients, showed a non-significant risk of developing overall endometrial pathologies. 2) Hysteroscopy may have missed some endometrial pathologies which were diagnosed later on in specimens obtained by hysterectomy.

The fetal cerebellar structure, size and consistency are looked at in every system survey. Among the acquired cerebellar events that might change the cerebellar consistency are haemorrhage, infections in utero and neoplasia. Additional fetal malformations, if present, assist in making the final diagnosis. We present a case of an isolated echogenic mass in one of the cerebellar hemispheres along with the differential diagnosis.

To evaluate possible predicting factors for endometrial cancer in postmenopausal breast cancer patients with tamoxifen treatment, we compared various clinical features between 12 postmenopausal breast cancer tamoxifen-treated patients with endometrial cancer and a control group of 261 otherwise similar patients without this endometrial pathology. These comparisons were based on a long-term prospective follow-up. Several clinical factors such as longer duration of breast disease, older patient age, lower frequency of chemotherapy administration, and higher frequency of postmenopausal bleeding were found among the tamoxifen-treated patients with endometrial cancers, and were significantly different when compared to the control group. Only eight (66.7%) had postmenopausal bleeding, and a preoperative diagnosis of endometrial cancer was made in only six (50.0%). When considering postmenopausal bleeding as a marker for endometrial cancer in the study patients, sensitivity was 67% and specificity was 98%.

Background: Endometrial polyps are the most common endometrial pathology described in association with postmenopausal tamoxifen exposure. It is generally accepted that the occurrence of malignancy in endometrial polyps among healthy women is up to 0.5%. However, no one has yet described the incidence of this malignant transformation among postmenopausal breast cancer tamoxifen-treated patients. Objective. The aim of this study was to study the exact rate of malignant changes in endometrial polyps recovered from postmenopausal breast cancer tamoxifen-treated patients., Methods: We reviewed the pathological results and medical records of all postmenopausal breast cancer patients in whom endometrial polyps were recovered following at least 6 months of tamoxifen treatment in our institute. We also looked for the rate of malignant changes in polyps recovered from all healthy postmenopausal controls with endometrial polyps in our institute during the period of the study., Results: Two (3.0%) of 67 endometrial polyps recovered from postmenopausal breast cancer tamoxifen-treated patients revealed malignant features. None of the clinical variables tested, including risk factors for endometrial cancer, was significantly different between the groups. In the controls only 5 (0.48%) of 1034 polyps were malignant., Conclusion: Up to 3.0% of endometrial polyps recovered from postmenopausal breast cancer tamoxifen-treated patients may show malignant changes. This rate is higher than that found in our controls as well as that reported in the general female population., (Copyright 1999 Academic Press.)

Objective: The aim of this study was to evaluate changes in transvaginal ultrasonographic endometrial thickness with increased duration of tamoxifen treatment in postmenopausal breast cancer patients., Material and Methods: In this prospective study we evaluated the changes (mean +/- SD) of endometrial thickness measured by transvaginal ultrasonography in 181 postmenopausal breast cancer patients, according to the duration of tamoxifen treatment. According to our protocol, the ultrasonographic evaluations were performed every 6 months for the first 2 years of the follow-up and every 12 months thereafter. Two such subsequent ultrasonographic evaluations were performed in 181 patients following 35.1 +/- 41.7 months of tamoxifen treatment, three studies in 127 patients following 44.7 +/- 47.98 months of treatment, four studies in 75 following 54.2 +/- 61.7 months of treatment, five studies in 51 patients following 65.3 +/- 74.4 months of treatment, and six studies in 27 patients following 79.5 +/- 98.8 months of treatment., Results: The measured endometrial thickness detected varied from 8.84 +/- 4.66 to 10.61 +/- 12.35 mm. There were no significant changes in mean +/- SD of endometrial thickness following various durations of tamoxifen treatment., Conclusions: Extension of duration of tamoxifen treatment in postmenopausal breast cancer patients up to 79.48 +/- 98.79 consecutive months does not cause a significant increase in transvaginal ultrasonographic endometrial thickness., (Copyright 1999 Academic Press.)

Menorrhagia in adolescents may be the presenting sign of a systemic hemostatic disorder. The evaluation of adolescents with menorrhagia should include an assessment of the pelvic organs to exclude anatomic pathology, and if none is found the possibility of primary hematological abnormality should be considered. Initially, a thorough personal and family history of a bleeding tendency should be obtained. Thereafter, we suggest a number of basic "screening" clotting assays be performed. These should include a platelet count, prothrombin time, activated partial thromboplastin time, fibrinogen level and bleeding time. Abnormalities of any of these tests should then be further investigated using more specific clotting assays. The most common disorders reported to cause menorrhagia in adolescents are von Willebrand's disease, factor XI deficiency, and Glanzmann's thrombasthenia. General and specific therapeutic measures for treating these disorders are discussed.

Objective: The purpose of the study was to assess the efficacy of sonohysterography combined with cytological analysis of the fluid retrieved from the endometrial cavity in predicting histological diagnosis., Study Design: A prospective study was conducted comparing sonohysterography combined with endometrial washings for cytology with histological evaluation after surgical procedures. Of 152 patients referred for sonohysterography, 87 were premenopausal and 65 were postmenopausal. Some of the injected fluid was aspirated for cytological analysis. Sixty-one patients (40%) underwent surgical hysteroscopy and eight (5%) had dilatation and curettage as a result of the sonohysterographic findings. Histological diagnoses were compared with the sonohysterographic and cytological findings., Results: In 99 (65%) patients, sonohysterography demonstrated endometrial polypoid lesions. Only 54 endometrial cavitary lesions were confirmed pathologically. Epithelial cells with atypia were more often found in patients without (five of 53) than in those with (two of 99) an endometrial polyp (p < 0.05). Only one out of nine cases of histological diagnosis of hyperplasia was predicted cytologically., Conclusions: The addition of cytological analysis of the fluid retrieved from the endometrial cavity during sonohysterography did not contribute to the prediction of benign histological diagnosis of endometrial hyperplasia.

Background: One result of the advancement in prenatal diagnosis is an increase in the need for second trimester pregnancy terminations. Extra-amniotic infusion of prostaglandins is a common technique used for such pregnancy termination. Since prostaglandins cause strong uterine contractions, many practitioners are hesitant to use this technique on women with a uterine scar. In this study we tried to evaluate the effectiveness and safety of the technique for women with a previous uterine scar., Methods: This retrospective study included all women with a complete medical record who underwent a second trimester pregnancy termination at our institution by extra amniotic prostaglandin E2, during a 6 year period. The study group included all women with a previous uterine scar. The group of women without such a scar served as the control group., Results: Three hundred and forty women had their pregnancy terminated, but only in 282 cases was the medical information complete (research population). The study group (35 women) characteristics were similar to those of the control group (247 women). We found no difference in the abortion interval, the need to use an additional method, the need for curettage and in bleeding complication between the two groups. There was no case of uterine rupture. The group of women with multiple uterine scars was too small for analysis., Conclusions: Our results suggest that extra amniotic prostaglandin infusion is an effective and safe technique in women with a uterine scar.

We present our experience of the sonographic prenatal diagnosis of dacryocystocele and review the literature. This lesion can be distinguished from a facial hemangioma, dermoid or anterior encephalocele by the ultrasound findings and Doppler flow studies. These conditions are separate entities and their associated diagnosis and prognosis are very different in each case. As dacryocystocele may be part of numerous syndromes, its prenatal visualization raises the rare possibility of associated anomalies.

Objective: To investigate the correlation between the histological patterns of vascularization and the resistance index (RI) in ovarian tumors., Design: In a retrospective study, the histological sections of the ovarian tumors with known preoperative RI values were reviewed and the pattern of vascularization was studied., Subjects: Twenty-two women underwent B-mode sonography and color Doppler ultrasound within 3 days prior to explorative laparotomy for ovarian masses in the years 1992-93., Methods: The RI of the ovarian tumors was calculated as the mean of three consecutive waveforms with the lowest RI. The representative histological sections were evaluated for quantity of arterioles and venules, after staining by Masson trichrome and Elastic Van Gieson. The arteriolar fraction (defined as the number of arterioles divided by the sum of the arterioles plus venules) and the density of vessels (defined as the number of arterioles and venules per microscopic field) were calculated in each histological section and correlated with the preoperative RI values., Results: The mean RI was 0.36 +/- 0.07 for malignant tumors and 0.57 +/- 0.03 for benign tumors. Ovaries with malignancies showed significantly lower arteriolar fraction values (0.30 +/- 0.12) than those with benign tumors (0.56 +/- 0.05) and those with metastatic tumors (0.43 +/- 0.2) (p < 0.002 and p < 0.001, respectively). The density of vessels was higher in malignant tumors (8.0 +/- 3.8) than in benign lesions (2.7 +/- 1.5) (p < 0.01). RI values showed a strong positive correlation (r = +0.85, p < 0.0005) with the arteriolar fraction and a negative and weaker correlation (r = -0.69, p < 0.001) with the density of vessels., Conclusions: RI values are predominantly determined by the proportion of arterioles. The correlation between the histological pattern of vascularization and RI values reflects tumor angiogenesis and increases understanding of the advantages and limitations of measuring vascular resistance by color Doppler ultrasound.

The present study evaluates the potential beneficial effect of co-treatment with LHRH-agonist in resolving premenopausal tamoxifen's induced supraphysiological serum 17beta estradiol levels and persistent ovarian cysts. Ultrasonographic and serum hormonal evaluations were performed before, during, and following three consecutive injections of long acting LHRH-agonist administered to 14 premenopausal breast cancer patients treated with tamoxifen, who had supraphysiological serum 17beta estradiol levels and simultaneous persistent ovarian cysts. Within 3 weeks of the first LHRH-agonist injection, all patients had menopausal serum estradiol levels. Ovarian cysts completely disappeared within 2 months following the first injection. Following the discontinuation of LHRH-agonist co-treatment, serum estradiol levels remained in physiological levels and the ovaries remained a normal size in 64.3% of the patients for 13.3 +/- 11.5 months. 28.6% of the patients had a gradual reappearance of high serum estradiol levels and of ovarian cysts, and were, therefore, treated with a second course of LHRH-agonist. Following the second course, serum estradiol levels remained in physiological levels and the ovaries remained a normal size for 8-15 months. It is concluded that short duration of co-treatment with long acting LHRH-agonist administered to premenopausal breast cancer patients treated with tamoxifen, successfully resolved the tamoxifen-induced supraphysiological serum 17beta estradiol levels and the ovarian cysts.

Aims: To evaluate whether endometrial pathology is more likely to be diagnosed in gynaecologically symptomatic rather than in gynaecologically asymptomatic postmenopausal breast cancer patients with tamoxifen treatment; and to evaluate the possible influence of various clinical factors on the incidence of endometrial pathology., Methods: Endometrial histological findings, transvaginal ultrasonographic endometrial thickness, demographic characteristics, health habits, and risk factors for endometrial cancer were compared between 14 gynaecologically symptomatic (group I) and 224 gynaecologically asymptomatic (group II) postmenopausal breast cancer patients with tamoxifen treatment., Results: Overall, 28.6% of the study population had endometrial pathology. The incidence of overall positive endometrial histological findings was significantly higher in group I than in group II (92.9% v 24.6%, p < 0.0001). Atrophic endometrium was more common in group II than in group I (75.3% v 7.1%, p < 0.0001). Most other endometrial pathology was significantly more common in group I than in group II (endometrial hyperplasia, 35.7% v 5.6%, p < 0.0001; endometrial polyps, 35.7% v 13.4%, p < 0.0111; endometrial carcinoma, 21.5% v 0.9%, p < 0.0001). Endometrial pathology appeared considerably later in the gynaecologically asymptomatic patients than in gynaecologically symptomatic patients (p = 0.0002). Vaginal bleeding or spotting occurred exclusively in group I. The incidence of endometrial pathology in the entire study population was consistent with that reported elsewhere, and higher than that reported for healthy postmenopausal women., Conclusions: Endometrial pathology is more likely to be diagnosed in gynaecologically symptomatic postmenopausal breast cancer patients with tamoxifen treatment, and after a shorter duration of time, than in gynaecologically asymptomatic patients.

The objective of this paper is to describe our experience with a desensitization protocol to paclitaxel using the original paclitaxel solution in patients following severe hypersensitivity reactions. A retrospective review of 75 consecutive patients with ovarian cancer who received intravenous paclitaxel-based chemotherapy between January 1996 and May 1998 at the Gynecologic Oncology Unit at Meir Hospital-Sapir Medical Center, Kfar-Saba, Israel. All patients who developed a hypersensitivity reaction to paclitaxel were treated with a desensitization protocol. The protocol included serial 10-fold dilutions (up to 1:100,000) of the actual paclitaxel infusate, delivered in successive volumes of 1, 2, 4, and 8 ml. These escalating doses of paclitaxel were given intravenously at 15-min intervals for each dilution. Following administration of the last diluted dose, the patient received a 1-ml dose of the undiluted solution. If no side effects were recorded, the rest of the actual dose was delivered at a 3-h infusion rate. Vital signs were monitored and recorded throughout the course of treatment. Six patients with a previous paclitaxel-associated hypersensitivity reaction were successfully treated with the desensitization protocol. In conclusion, we demonstrate that the desensitization protocol is feasible and safe without compromising cytotoxic activity. Our results show that this strategy is a reasonable choice in this clinical setting and potentially avoids paclitaxel-based regimen interruption.

To assess whether a higher cumulative tamoxifen dose is associated with increased incidence of various types of endometrial pathologies, we compared cumulative dose of tamoxifen treatment as well as demographic characteristics, risk factors for endometrial cancer, transvaginal ultrasonographic endometrial thickness, and various treatments for the primary breast cancer between 159 postmenopausal breast cancer tamoxifen-treated patients without endometrial pathologies (group I) and 67 similar patients with endometrial pathologies (group II). A similar comparison was made between group I patients and similar patients with proliferative endometrium (group IIa), with endometrial hyperplasia (group IIb), with endometrial polyps (group IIc), and with endometrial cancer (group IId). Overall cumulative tamoxifen dose was significantly higher in group II as compared to group I (27.4+/-33.4 and 17.4+/-20.2, respectively; P<0.0252). Transvaginal ultrasonographic endometrial thickness was significantly higher in group II than in group I patients (16.3+/-11.3 mm and 12.1+/-6.3 mm, respectively; P<0.0147). The frequency of diabetes mellitus, of previous postmenopausal bleeding, and of previous exposure to hormone replacement therapy was significantly higher in group II than in group I patients (P<0.001, P<0.0001 and P<0.001, respectively). There were no significant differences in all parameters tested between group I, group IIa, group IIb, group IIc, and group IId. However, there was an obvious trend for higher cumulative tamoxifen dose in patients with benign endometrial pathologies as compared to those without endometrial pathologies or to those with endometrial cancer (Group I = 17.4+/-20.2 g, group IIa = 22.5+/-18.5 g, group IIb = 28.1+/-20.3 g, group IIc = 31.4+/-42.7 g and group IId = 10.4+/-12.6 g). Endometrial pathologies, except for endometrial cancer, are associated with a high cumulative dose of tamoxifen in postmenopausal breast cancer patients.

Aim: Tamoxifen is the antihormonal treatment of choice for premenopausal breast cancer patients with advanced breast disease. Its premenopausal administration has been shown to induce supraphysiological 17beta-estradiol serum levels and to be associated with the presence of persistent, bilateral functional ovarian cysts. However, these abnormalities have not yet been compared to controls. In this study we evaluated the possibility that the above hormonal and/or ovarian abnormalities are more frequent among premenopausal breast cancer patients treated with tamoxifen than among similar nontreated patients, and thus they may be attributed to tamoxifen effect., Methods: We evaluated serum hormone levels of 17beta-estradiol, follicular-stimulating hormone, luteinizing hormone, and progesterone, the presence of ovarian cysts, and various demographic and clinical characteristics in 20 premenopausal breast cancer patients treated with tamoxifen (study group) and compared them to those observed in 12 similar nontreated patients (control group)., Results: Ovarian cysts were found in 80% of the study patients and only in 8.3% of the control patients (P = 0.001). The incidence of oligomenorrhea was nearly significantly higher in the study than in the control group (50 and 16.7%, respectively; P = 0.0651). Various serum hormone levels tested were not found to be significantly different between the two groups, except for 17beta-estradiol serum levels as detected on days 14 and 21 of the menstrual cycle, which were significantly higher among the study than in the control patients. (Day 14 serum estradiol: 757.7 +/- 372.0 pg/mL versus 206.5 +/- 275.0 pg/mL, P = 0.0012. Day 21 serum estradiol: 300.0 +/- 134.5 pg/mL versus 96.5 +/- 71.5 pg/mL, P = 0.0008.), Conclusions: Tamoxifen treatment increases the incidence of ovarian cysts and the significantly higher 17beta-estradiol serum levels in premenopausal breast cancer patients., (Copyright 1999 Academic Press.)

Management of male infertility has recently shifted from treatment of the subfertile man towards techniques of assisted reproduction (ART). This study aimed to evaluate the possible role of the ultramorphological status of the spermatozoon with respect to sperm selection in vivo and prediction of ART success. Ultramorphological sperm parameters were assessed retrospectively for 92 males with sufficient sperm density (10(7) spermatozoa ejaculate-1) whose wives conceived following a stepwise discarding of the female genital tract barriers, using intra-uterine insemination (IUI) (n = 26), in vitro fertilization (IVF) (n = 45) or intracytoplasmic sperm injection (ICSI) (n = 21). In parallel, sperm samples of 71 fertile males were examined. Normal ultramorphology of all head and tail subcellular organelles was found to be essential for the ability of spermatozoa to pass the lower female genital tract. The ultramorphological migration threshold for this barrier is apparently higher than that essential for oocyte fertilization. No specific indication associated with passage through the upper genital tract was found. A high prevalence of axonema defects was found to impair the ability of sperm cells to penetrate the oocyte investment. The natural fertility index, based on routine sperm parameters and the ultrastructural status of the spermatozoon's subcellular organelles was confirmed to be beneficial for directing patients to ART. A discriminative score based on axonema integrity was found to contribute additional information for the first choice decision between conventional ART and ICSI (75% prediction ability). Thus it may be helpful in finding the simplest and least expensive procedure with the greatest long-term chance for pregnancy.

Histological findings of endometrial specimens collected by hysteroscopy from 261 postmenopausal breast cancer patients with tamoxifen treatment (group I) and from endometrial specimens obtained following hysterectomy from 40 similar patients (group II) were compared. This comparison was performed in order to assess whether endometrial pathologies are more frequently diagnosed in specimens collected by hysterectomy than by those collected during hysteroscopy in such patients. Overall positive endometrial histological findings were significantly more common in group II patients than in group I patients (82.5 and 24.5%, respectively; p < 0.0001). Atrophic endometrium was significantly more common in group I patients than in group II patients (75.5 and 15.0%, respectively; p < 0.0001). All other different endometrial pathologies, except for proliferative endometrium, were significantly more common in group II patients than in group I patients (endometrial hyperplasia = 17.5 and 4.2%, respectively; p < 0.0003; endometrial polyps = 30.0 and 11. 5%, respectively; p < 0.006; endometrial polyps with hyperplasia = 17.5 and 4.2%, respectively; p < 0.0003; endometrial carcinoma = 15. 0 and 0.4%, respectively; p < 0.0001). These findings suggest that in postmenopausal breast cancer patients treated with tamoxifen, the frequency of various endometrial histological findings and of overall positive endometrial histological findings were significantly higher in specimens collected by hysterectomy than in specimens obtained by hysteroscopy.
