Abstract
BACKGROUND Israel has been the destination of large numbers of illegal migrants from East African countries in recent years. Despite efforts to detect and treat active tuberculosis (TB) at the border, 75% of all active TB cases diagnosed in our hospital were illegal migrants. In 2012, there was a large-scale TB exposure in our maternity ward, neonatal, and paediatric intensive care units following the admission of an infectious but apparently asymptomatic migrant who was in labour. A hospital-wide screening programme was subsequently implemented to prevent exposure of patients and staff to TB. AIM To report the results of the first year of this intervention in the maternity hospital. METHODS All illegal migrants from countries where TB is highly prevalent were screened by chest radiography (CR) upon admission to the maternity hospital. The results were immediately categorized by a radiologist as either 'suggestive of active pulmonary TB' or 'non-suggestive'. Patients with CR suggestive of TB were placed in airborne isolation and underwent further evaluation. FINDINGS Four hundred and thirty-one apparently asymptomatic migrant women underwent CR screening. Most (363, 84%) presented in labour. Eleven women (2.6%) had a CR suggestive of active pulmonary TB which was confirmed in three (0.7% of screened women). No TB cases were missed by the CRs. Neither patients nor hospital staff were exposed to TB. CONCLUSION Targeted CR screening for TB among high-risk women upon their admission to a maternity hospital had a high yield and was an effective strategy to prevent in-hospital transmission of TB.

Abstract
OBJECTIVE To determine the utility of a modified version of ovarian cancer-focused cancer risk evaluation and early detection (CADET) scores as a screening tool for ultrasonographic ovarian findings. STUDY DESIGN Prospective pilot study. MAIN OUTCOME MEASURES CADET scores were compared with abnormal ultrasonographic ovarian findings of peri- and postmenopausal women who attended their gynecologist for a routine check-up. The women filled in the CADET questionnaire before seeing their gynecologists who were blinded to the CADET results. The women whom they referred for pelvic transvaginal ultrasonographic examination comprised the study group. The results of their scans were compared with their CADET scores. RESULTS Of the 181 peri- and postmenopausal women who were candidates for this study, 154 were referred for ultrasonography, of whom 38 (24%, Group A) had abnormal ovarian scans (30 simple cysts and 8 complex findings). The other 116 (76%) women had normal sonograms (Group B). Demographic characteristics were similar for both groups. Thirteen Group A women (34%) and 52 Group B women (45%) had positive CADET scores (p = NS). The average group CADET scores were also not significantly different (0.8 +/- 1.7 for Group A and 1.7 +/- 2.5 for Group B). CONCLUSION CADET scores did not correlate with abnormal ultrasonographic ovarian findings.

Abstract
AIM The study aimed to evaluate the current risk factors for severe perineal tears in a single university-affiliated maternity hospital. METHOD An obstetric database of 31 784 consecutive women who delivered from January 2007 to December 2009 was screened for cases of third-degree or fourth-degree perineal tears. Four controls, matched by time of delivery, were selected for each case of third- or fourth-degree perineal tear. Maternal and obstetric parameters were analyzed and compared between the study and control groups. RESULTS Sixty women (0.25% of all vaginal deliveries) had a third-degree (53 women) or a fourth-degree (seven women) perineal tear. The control group comprised 240 matched vaginal deliveries without severe tears. Primiparity, younger maternal age, Asian ethnicity, longer duration of second stage of labour, vacuum-assisted delivery and heavier newborn birth weight were significantly more common among women who had third- or fourth-degree perineal tears. Of the variables that were found to be statistically significant in the univariate analysis, only primiparity (OR = 2.809, 95% CI: 1.336-5.905), vacuum delivery (OR = 10.104, 95% CI: 3.542-28.827) and heavier newborn birth weight (OR = 1.002, 95% CI: 1.001-1.003) were found to be statistically significant independent risk factors for severe perineal trauma. CONCLUSION Identification of women at risk may facilitate the use, or avoidance, of certain obstetric interventions to minimize the occurrence of childbirth-associated perineal trauma.

Abstract
In a population of 8500 men attending the andrology outpatient clinic, 200 men (2.35%) were recorded as having some disturbances with the descent of the testes into the scrotum. Medical history of the patients revealed that 51 underwent unilateral orchidopexy; 40 bilateral orchidopexy; and 24 were treated with human chorionic gonadotropin in order to induce descent of their testes. In addition, 6 patients reported spontaneous descent of the testes, and 13 others were found to be unilaterally cryptorchid upon physical examination. Results of semen analysis, hormonal profile, testes position, and testicular volume were compared to those of 105 proven fertile men. The major finding of this study shows that post-partum undescended testes suffer from primary Sertoli cell malfunction as reflected by elevated serum follicle stimulating hormone levels. Serum luteinizing hormone and testosterone levels were within the normal range. Surgical descent of the testes did not improve sperm production, proved by low sperm quality of all the study groups, compared to the cryptorchid group. Among the patients who were operated on, no correlation was found between age at operation and semen variables. All groups showed poor sperm quality which can be defined as oligoteratoasthenozoospermia. The degree of spermatogenic damage was in the following order of diagnosis or treatment: bilateral orchidopexy greater than cryptorchid testes greater than hormonal treatment greater than unilateral orchidopexy greater than late spontaneous descent of the testes. Thus, it is advisable to postpone surgical treatment of cryptorchidism and apply this only after a waiting period, and if the hormonal approach has failed to descend the testis.

Abstract
AIMS We report the results of hyperbaric oxygen therapy (HBOT) used in the treatment of radiation-induced persistent side-effects after the irradiation of pelvic tumours. MATERIALS AND METHODS Between January 2001 and December 2005, 13 women (median age 60.3 years) with radiation combined proctitis/cystitis (n=6), longstanding vaginal ulcers and fistulas (n=5) and longstanding skin injuries (n=2) underwent HBOT in a multiplace chamber for a median of 27 sessions (range 16-40). The treatment schedule was HBOT 100% oxygen, at 2 absolute atmospheres, for 90 min, once a day. For radiation-induced toxicity grading we used the National Cancer Institute Common Toxicity Criteria (CTC) grading system, before and after HBOT. RESULTS Thirteen patients underwent an adequate number of HBOT sessions. The mean CTC grading score before HBOT was 3.3+/-0.75, whereas the mean CTC grading score after HBOT was 0.3+/-0.63. The scores showed a significant improvement after HBOT (P=0.001; exact Wilcoxon signed-rank test). Rectal bleeding ceased in five of six patients with proctitis and dysuria resolved in six of seven cystitis patients. Macroscopic haematuria stopped in seven of seven patients. Scar complications resolved in two of two patients. None reported HBOT-associated side-effects. CONCLUSION HBOT is apparently safe and effective in managing radiation-induced late side-effects, such as soft tissue necrosis (skin and vagina), cystitis, proctitis and fistulas.

Abstract
Application of an in-line positron emission tomography and computerized tomography (PET-CT) in endodermal sinus tumor (EST) is described in this study. CASE 1: A young female with massive ascites postovarian mass resection had elevated alpha-fetoprotein (AFP) serum levels. Following a positive PET-CT study with increased (18)F-fluorodeoxyglucose (FDG) uptake, a CT-guided core biopsy of a peritoneal mass was performed. EST was diagnosed histologically. The patient was disease free after chemotherapy. Follow-up PET-CT was negative in keeping with no viable tumor tissue. CASE 2: A large pelvic mass diagnosed histologically as primarily EST was removed in a teenage patient with elevated AFP levels. PET-CT showed diffuse abdominal spread of FDG uptake, suggesting extensive peritoneal seeding. The patient was disease free after chemotherapy. Follow-up PET-CT was negative. EST is an FDG-avid tumor. PET-CT delineated the prechemotherapy tumor extent adequately ruled out the presence of residual tumor after a successful treatment.

Abstract
Fertility preservation is of major importance for women with cancer in whom ovarian function may be disturbed by the use of potentially sterilizing chemotherapeutic drugs and/or pelvic irradiation. Cryopreservation of ovarian cortical tissue is one of the potential options for preserving fertility among these women. Cryopreserved thawed human ovarian tissue can be autografted either orthotopically or heterotopically, but may also be transplanted first into an animal host with subsequent maturation and collection of oocytes. The objective of this study was to investigate the prevalence of ovarian follicular apoptosis in fresh and frozen/ thawed human ovarian tissue as a measure of follicular viability. The study group included 6 women with cancer who underwent ovarian tissue cryopreservation (OTCP). Ovarian tissue samples (n = 2) were obtained from each woman with one sample undergoing evaluation for apoptosis immediately following removal (control, group A) and the other evaluated for apoptosis following freezing/thawing (group B). Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labeling (TUNEL) and 4'6' diamido-2-phenylindole hydrochloride (DAPI) staining methods were used to investigate follicular apoptosis. Morphological changes in the same samples were evaluated in hematoxylin and eosin (H&E)-stained sections. In each slide, only primordial and primary follicles were evaluated for abnormal morphology and apoptosis. Abnormal morphology was demonstrated in 23.8+/-8.7% of group A follicles compared to 48.3+/-11.2% of group B follicles (p < 0.05). Apoptosis was demonstrated in 25.4+/-8.4% of group A follicles compared to 60.9+/-6.0% of group B follicles (p < 0.05). We have shown that the ovarian follicles in group B demonstrated a higher incidence of apoptosis compared to those of group A. Therefore, the data suggest that follicular apoptosis might be a consequence of the freezing and thawing procedure. This may be used as a method for evaluating and comparing the outcome of different freezing/thawing protocols.

Abstract
A unique cast model of the placenta in a rare case of feto-feto-fetal triplet transfusion syndrome (FFFTTS) allowed the demonstration of why the transfusion syndrome developed in one fetus and not in the other two in that single placenta. The vasculature anatomy of a monochorionic triamniotic triplet placenta with FFFTTS of three healthy infants (one donor, two recipients) born in the 35th week of gestation was cast by means of dental casting materials. After the cast hardened, the tissue was corroded, revealing the cast blood vessels. The diameters and lengths of the chorionic blood and intraplacental vessels of the cast placenta were measured with a digital caliper. The cast revealed two artery-artery (A-A) anastomoses on the chorionic plate between the two recipients and the donor. Seven artery-vein (A-V) deep anastomoses connected only the arteries of the donor and the veins of the two recipients. The blood vessel connections among the fetuses allowed the evaluation of a pathologic case with its own control in a single placenta. From the vascular appearance, we speculate that the A-A anastomoses between the two fetuses protected them from developing blood transfusions, but that the A-V anastomoses contributed to their development.

Abstract
Polycystic ovarian syndrome is seen in 5% of fertile aged women. However, there is no satisfactory PCOS model in experimental animals. To induce polycystic ovary phenotype in immature female rats, Wistar rats 21 days of age were injected daily with testosterone propionate 1 mg/100 g body weight dissolved in propylene glycol or propylene glycol for up to 35 days. Seven days of injection with testosterone (T) resulted in the appearance of large cystic follicles and a dramatic accumulation of multi-layer preantral follicles. At 42 days of age puberty in control animals was evident by the appearance of corpora lutea. In contrast in T treated animals no corpora lutea formation was seen even at the age of 56 days. Progesterone in the control animals was elevated at the age of 42 days in contrast with the T treated animals in which progesterone remained low (20% of control). While during 14 days of T injection most of the follicles did not have progressive apoptosis, at 21-35 days of injection (42-56 days of age) the vast majority of follicles became apoptotic. Progressive degeneration of oocytes was evident in T treated animals reaching 70-85% of total oocytes at 21-35 days of T injection compared to 30-40% in control animals. Western blot analysis of ovarian homogenates revealed gradual decrease in Bcl-2 content, evident at 28 and 35 days of T injection compared to control animals. Interestingly, the fasting glucose/insulin ratio was dramatically reduced in T treated animals following 14 days of testosterone treatment compared to controls. Our data suggest that T injection to immature female rats can induce polycystic ovaries, block ovulation and attenuate progesterone production. Moreover, normal/low glucose and high insulin blood levels in the testosterone treated rats raises the possibility that elevated androgens can lead to insulin resistance in this experimental PCOS model.

Abstract
The adjusted incidence of cervical carcinoma among Israeli Jewish women is ∼5 out of 100 000. This retrospective study sought to determine the clinical implications of finding atypical glandular cells of undetermined significance (AGUS) in cervical cytologic specimens in this population. Cervical cytologic examinations during January 2001–June 2003 diagnosed as AGUS were identified by a computerised database. Medical records were reviewed to determine the presence or absence of associated significant pathologic conditions of the cervix and identified 45 out of 11 800 patients (0.38%) with AGUS. AGUS was the only cytologic diagnosis in 14 patients, while 31 patients had both AGUS and an additional atypical squamous cell of undetermined significance (ASCUS). All subjects underwent colposcopy, endocervical curettage, and cervical biopsy. A clinically significant diagnosis (cervical intraepithelial neoplasia (CIN) II, CIN III, or carcinoma) was made in 24 patients (53.3%), including cancer in three (6.7%): one had microinvasive adenocarcinoma and two had microinvasive squamous cell carcinoma. Squamous carcinoma coexisting with a clinically significant lesion carried a risk of 61.3%, compared with a risk of 35.7% for AGUS alone (P=0.20). Detection of AGUS during cervical cytologic screening, especially with a coexisting ASCUS, indicates the existence of serious pathologic processes; management by cervical colposcopy, endocervical curettage, and cervical biopsy is recommended.

Abstract
Hyperemesis gravidarum is a severe form of nausea and vomiting during the first trimester of pregnancy. Our objective was to assess the feasibility of nasojejunal feeding in our patients. Eleven pregnant women aged 23-46 years with hyperemesis gravidarum, persisting in spite of an in-hospital treatment of 2-15 days by intravenous fluids and antiemetic drugs and accompanied by weight loss, consented to have a nasojejunal feeding tube inserted endoscopically. Mean in-hospital weight loss prior to tube insertion was 2.2+/-1.1 kg (range 0.9-5.1 kg). A clear reduction in the extent of vomiting was already apparent within the first 48 h after tube insertion, but vomiting ceased completely after a mean of 5+/-4 days (range 1-13 days). Weight gain was recorded in six patients who stayed on tube feeding for more than 4 days. Patients were encouraged to start drinking and eating along tube feeding after 3-4 days. Ceasing vomiting and a concomitant sufficient oral intake of at least 1000 kcal/day resulted in the decision to remove the tube after 4-21 days. In three cases, however, the tube was expelled by recurrent vomiting after 1-4 days, or was blocked as in one case. The tube was not reintroduced and patients did not resume vomiting. There were no complications associated with this feeding approach in this population. Only one patient was readmitted. None of the rest resumed vomiting after tube withdrawal.The above suggests that nasojejunal enteral feeding can be an effective option in hyperemesis gravidarum persisting despite intravenous fluids and antiemetic drugs.

Abstract
PROBLEM The presence of interleukin-18 (IL-18) in serum and pre-ovulatory follicular fluid (FF) and its possible correlation to in-vitro fertilization/embryo transfer (IVF/ET) outcome and ovarian hyperstimulation syndrome (OHSS) development. METHOD OF STUDY A prospective study was carried out. Assays for serum and pooled pre-ovulatory FF levels of IL-18 were performed on 30 patients who underwent oocyte retrieval for IVF/ET. RESULTS Mean serum and FF levels of IL-18 were 370.4 +/- 224 and 228.9 +/- 208 pg/mL, respectively (r = 0.77, P < 0.0001). Levels of FF IL-18 were comparable between the two ovaries (right = 221 +/- 166.8 pg/mL, left = 237 +/- 171.9 pg/mL; r = 0.7550, P = 0.49). A positive correlation was found between IL-18 FF levels and number of retrieved oocytes (r = 0.45; P = 0.019). In three patients (10%) who developed OHSS, the mean serum level of IL-18 at day of ovum pickup was significantly higher compared with patients without OHSS (620 +/- 196 pg/mL versus 345 +/- 251 pg/mL, respectively, P = 0.04). CONCLUSIONS Both pre-ovulatory FF and serum levels of IL-18 correlate with the number of retrieved oocytes. The serum IL-18 level at day of ovum pickup may predict consequent development of OHSS. Further investigations are warranted to determine the role of IL-18 in the folliculogenesis and OHSS pathogenesis.

Abstract
BACKGROUND Many theories regarding the pathophysiology leading to ovarian hyperstimulation syndrome (OHSS) have been proposed and tested. Increased erythrocyte aggregation is associated with capillary slow flow and tissue hypoxaemia. We performed this study in order to assess the degree of erythrocyte aggregation in the peripheral blood of individuals with OHSS and undergoing controlled ovarian stimulation (COH). METHODS Twenty women with severe OHSS, 20 women undergoing COH under IVF protocol, and 20 healthy matched controls were recruited for this prospective study. Blood samples were drawn for determination of erythrocyte aggregation as well as haematological indices. The percentage of slide covered by the cells ('erythrocyte percentage': EP) was determined using a simple slide test and image analysis. Lower EP values correspond to higher degrees of aggregation. RESULTS The respective measures of EP were 59.2 +/- 3.0, 42.0 +/- 3.0 and 35.0 +/- 2.4% micro m for the controls, women with COH and OHSS (P < 0.01 between controls and the two stimulation groups). CONCLUSIONS The degree of erythrocyte aggregation is enhanced in the peripheral venous blood of patients with both COH and OHSS. This finding, known to cause capillary leak, may contribute to the pathophysiology of the OHSS.

Abstract
BACKGROUND The LC Polscope facilitates visualization of the meiotic spindle in human oocyte. This study aimed to investigate meiotic spindle assembly in correlation to time elapsed after HCG administration, and to determine whether spindle imaging may serve to indicate the likelihood of fertilization and embryo cleavage. METHODS Metaphase II (MII) oocytes from 103 couples who were being treated for male infertility were imaged with the Polscope prior to sperm injection. Spindle imaging was correlated to time elapsed from HCG administration, fertilization rate and embryo cleavage. The main outcome measures were spindle visualization, fertilization and embryo cleavage on day 3. RESULTS A total of 770 MII oocytes were imaged. A spindle was imaged in a significantly higher number of oocytes from >or=38 h after HCG administration compared with those in the <38 h group (78.1-81.5% versus 61.6%; P < 0.001). The fertilization rate in oocytes with a visible spindle was statistically higher compared with oocytes in which spindle could not be detected (70.4% versus 62.2%; P = 0.035). We found no relationship between spindle imaging and embryo cleavage on day 3. CONCLUSIONS Spindle imaging, in addition to first polar body appearance, is an accurate indicator for oocyte maturity. We suggest that spindle imaging be performed prior to sperm injection.

Abstract
This study aimed to evaluate the clinical and economic implications of integrating human papilloma virus (HPV) load testing into the follow-up and management protocol of women postconisation for high-grade cervical intraepithelial neoplasia (CIN2-3). We evaluated 130 suitable women: 63 were screened biannually by Pap smears ('conventional approach') and 67 also had HPV-load testing ('HPV approach'). More stringent criteria for undergoing colposcopy or reconisation were observed by the former group compared to the latter. Both approaches were analysed for cost effectiveness. There were 33 out of 67 (49.2%) colposcopic referrals and 24 out of 67 (35.8%) reconisation/hysterectomies with the 'conventional approach' compared to 9 out of 63 (14.2%) and 7 out of 63 (11.1%) with the 'HPV approach'. Cervical intraepithelial neoplasia 2-3 residual disease was detected in 7 out of 67 (10.5%) and 7 out of 63 (11.1%) women. The 'conventional approach' had more negative colposcopic biopsies and more negative reconisation/hysterectomy histologies than the 'HPV approach'. The respective cost per detection of one case of residual disease was US$3573 and US$3485. The 'HPV approach' required fewer colposcopic and reconisation procedures to detect one case of residual CIN2-3. Its higher positive predictive value than that of cytology provided a significant decrease in false positive rates and a reduction of US$88 per detected case.

Abstract
The objective of this paper is to assess whether ovarian hyperstimulation and in vitro fertilization (IVF) are associated with increased risk of cancer development, using an historical cohort analysis of infertile women who attended the IVF unit, Lis Maternity Hospital Tel Aviv Medical Center, Tel Aviv, Israel. One thousand and 82 women participated in the IVF treatment program between 1984 and 1992. Cancer incidence rates were determined through the National Cancer Registry and were compared to the expected rates with respect to appropriate age and continent of birth. Twenty-one cases of cancer were observed as compared to 11 that were expected (SIR 1.91; 95% CI 1.18–2.91). When cancer cases that were diagnosed within one year of the IVF treatment were excluded from the analysis (SIR = 1.46; 95% CI 0.83–2.36), no significant excess risk of cancer was noted. We conclude that in this cohort of infertile women, the higher than expected cancer rate could not be attributed to IVF treatments. Special attention should be made to women who may be diagnosed with cancer during or shortly after IVF treatment.

Abstract
The objective of the present study was to evaluate the association between the expression of sperm mannose-ligand receptors and sperm morphology. Sperm samples were obtained from 45 men, 30 fertile sperm donors and 15 infertile men. Sperm concentration, motility and morphology were evaluated and then incubated with control medium (Ham's F-10 + 1% HSA) for 4 h. Expression of mannose-ligand receptors was evaluated by mannosylated-BSA-FITC (subdivided into 3 patterns: I, for uncapacitated sperm; II, for capacitated; and III, for acrosome-reacted sperm). The mean (+/- SE) frequencies of sperm cells of the total sperm population that expressed patterns I, II, and III were 88 +/- 2.1%, 7 +/- 1.6%, and 5 +/- 0.8%, respectively, for fertile men, and 90 +/- 2.1%, 7 +/- 1.3%, and 3 +/- 0.5%, respectively, for infertile men. The rate of pattern III expression of mannose-ligand receptors was significantly higher in the fertile group compared to the infertile patients (p <.01). A poor but significant correlation was observed between the rate of pattern III and the percentage of normal-forms sperm cell in the ejaculate (r =.35, p =.018). Fertile sperm samples express more advanced patterns of mannose-ligand receptors compared to infertile men. This phenomenon is related to the morphology of human sperm cell in the ejaculate more than to any other basic sperm characteristics.

Abstract
OBJECTIVES To assess the contribution of additional examiners to: the average discrepancy between estimated and actual fetal weights; the correlation between estimated and actual fetal weights; the reduction in major (> 10%) discrepancies between estimated and actual fetal weights. DESIGN Three experienced sonographers independently measured fetal biparietal diameter, head circumference, abdominal circumference and femur length in 39 fetuses at term. The estimated fetal weights were calculated for each examiner. Fetal biometric measurements were analyzed to obtain the source of differences in estimations among the examiners. Discrepancy, correlation and number of major (> 10%) discrepancies between the estimated and actual fetal weights were calculated for each examiner, and the contribution of additional examiners was analyzed. RESULTS The differences in measurements of the biparietal diameter and femur length were lower than those of the head and abdominal circumferences. For each of the three examiners, the average discrepancy between the estimated and actual fetal weights was 6.1%, 5.9% and 6.3%. When the estimation was based on two examiners, the discrepancy decreased to 4.8-5.6%. The contribution of a third examiner was nil. Major (> 10%) discrepancies between estimated fetal weight and actual birth weight were found in seven, eight and nine estimations of the examiners. Estimation by two examiners decreased the number of major discrepancies, and estimation by all three examiners further decreased by approximately 50% the number of major discrepancies between the estimated and actual fetal weights. CONCLUSION Measurements by multiple examiners changes only slightly the average number of discrepancies between estimated and actual fetal weights. However, the reduction in major (> 10%) discrepancies is statistically and clinically significant.

Abstract
The study was conducted to evaluate the significance of preoperative clinical parameters for detection of mature testicular sperm cells in nonobstructive azoospermic men. Sixty-five consecutive men with nonobstructive azoospermia underwent testicular sperm extraction procedures. Testicular samples were analyzed histologically with patterns classified as mature spermatogenesis (normal or partial), arrest of spermatogenesis, and Sertoli cell only. Testicular sperm cells were isolated for use in an IVF/ICSI program. Histologic patterns and detection rate of sperm cells were correlated to clinical characteristics. Mature sperm cells were found in all levels of serum FSH. The men were divided into 3 groups based on their clinical characteristics (serum FSH level and testicular size). The distribution of the different testicular histologic patterns, as well as detection rate of sperm cells, was similar in all groups. No correlation was found between serum levels of FSH, LH, prolactin, or testosterone and sperm presence. None of these parameters, nor the testicular size and consistency, can serve as predictive variables of the histological pattern or the presence of mature sperm cells in the testicular biopsies in cases of nonobstructive azoospermia. Until an effective predictive tool is available, a trial of sperm retrieval is recommended for all azoospermic men independent of their clinical characteristics.

Abstract
OBJECTIVE To evaluate the benefit of combined low-molecular-weight (LMW) heparin and aspirin for prophylaxis in women carriers of thrombophilia who had previously suffered from severe obstetric complications. METHODS The 33 studied women had an earlier pregnancy complicated by severe preeclampsia, abruptio placentae, intrauterine growth retardation, or intrauterine fetal death. All were subsequently diagnosed as carrying inherited thrombophilias. In their subsequent pregnancy, prophylactic therapy consisting of LMW heparin 40 mg/day (Enoxaparin, Rhone-Poulenc-Rorer, France) and aspirin was administered. Patients who were found to be homozygotes for the methylenetetrahydrofolate reductase mutation also received folic acid supplementation throughout their pregnancy. RESULTS Low-molecular-weight heparin was well tolerated and none of the women or the newborns developed any hemorrhagic complications. Only three (9.1%) of the women developed pregnancy complications. The mean gestational age and the mean birth weight at delivery in the previously complicated pregnancies were 32.1 +/- 5.0 weeks and 1175 +/- 590 g, respectively, compared to 37.6 +/- 2.3 weeks and 2719 +/- 526 g, respectively, in the treated pregnancies (p < 0.001). CONCLUSIONS This uncontrolled trial suggests that patients with obstetric complications and an inherited thrombophilia may benefit from treatment with combined LMW heparin and aspirin in subsequent pregnancies. However, this needs to be verified by controlled trials before considering clinical application.

Abstract
OBJECTIVES To conduct a prospective evaluation of the incidence and neonatal outcome of fetuses with persistent right umbilical vein. This condition had traditionally been considered to be extremely rare and to be associated with a very poor neonatal prognosis, but later evidence has raised some doubts about the veracity of these contentions. METHODS Between August 1995 and November 1998, 8950 low-risk patients were prospectively evaluated at two medical centers. The sonographic diagnosis of a persistent right umbilical vein was made in a transverse section of the fetal abdomen when the portal vein was curved toward the stomach, and the fetal gall bladder was located medially to the umbilical vein. RESULTS Persistent right umbilical vein was detected in 17 fetuses during the study. Four of them had additional malformations, of which three had been detected antenatally. CONCLUSIONS We established that the incidence of persistent right umbilical vein in a low-risk population is 1 : 526. We believe that the sonographic finding of this anomaly is an indication for conducting targeted fetal sonography and echocardiography. When the persistent right umbilical vein is connected to the portal system and other anomalies are ruled out, the prognosis can generally be expected to be favorable.

Abstract
OBJECTIVE To investigate placental apoptosis in discordant dichorial twins. METHODS Placental samples were obtained from 7 third-trimester suitable twins. Discordancy was defined as a >25 per cent difference in newborn birth weight. Light microscopy using hematoxylin and eosin (H&E)-stained paraffin slides and terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labelling (TUNEL) methods were used to confirm the incidence of apoptosis. Investigators were blinded to pregnancy outcome. RESULTS Both methods revealed that the incidence of apoptosis in the placentas of the smaller fetuses was significantly higher than in placentas of the larger fetuses. The incidence of TUNEL-positive cells in the former was 1.4+/-0.26 per cent: this was significantly higher than the incidence of apoptosis in the placental specimens of the latter (0.9+/-0.07 per cent, P< 0.02 Wilcoxon rank test). The same results were obtained with H&E: the incidence of apoptosis detected in placentas from the former was 1.07+/-0.1 per cent compared to 0.72+/-0.08 per cent in those of the latter (P< 0.02 Wilcoxon rank test). CONCLUSIONS Despite similar environment conditions, placental apoptosis is increased in the smaller fetus and thus might play a role in discordancy between twins. Since increased placental apoptosis has also been found in singleton intrauterine growth restriction, this supports the hypothesis that the smaller twin is selectively growth restricted.

Abstract
We established the effects of the supine position on umbilical blood flow when measured during the third trimester in 30 multiparous, normotensive patients. Blood flow in the umbilical and uterine arteries and blood pressure in the brachial and popliteal arteries were blindly taken by two different observers: first in the lateral and 5 min later in the supine position. There was a significant difference in mean blood pressure between the two postures. However, there was no statistical difference in the pulse pressure or in systolic/diastolic ratio in the umbilical and uterine arteries between the two positions. Postural changes in normotensive multiparous patients do not affect uterine and umbilical blood flow during the third trimester of uncomplicated pregnancies.

Abstract
OBJECTIVE To compare placental pathology between women with and without thrombophilia who had severe preeclampsia, intrauterine growth retardation, severe abruptio placentae, or stillbirth. METHODS After delivery, 68 women with singleton pregnancies with one of the above complications were evaluated for an inherited thrombophilia: factor V Leiden, methylenetetrahydrofolate reductase and prothrombin gene mutation, and deficiencies of protein S, protein C, and antithrombin III. Thirty-two women were thrombophilic (group A), and 36 women were not (group B). There was no difference in maternal age, parity, and type of pregnancy complication. A single pathologist examined each placenta. RESULTS The gestational age at delivery, birth weight, and placental weight were significantly lower in group A. Three parameters showed significant differences between the groups: thrombophilic women had a higher number of villous infarcts (P <.01), more multiple infarcts (P <.05), and a higher incidence of placentas with fibrinoid necrosis of decidual vessels (P <.05). CONCLUSION Placentas of women with severe complications and thrombophilia have an increased rate of vascular lesions.

Abstract
The objective of this study was to determine the seminal concentrations of four different catecholamines and their association with semen quality. Seminal concentrations of adrenaline, noradrenaline, 3,4-dihydroxy-phenylalanine (DOPA), and 3,4-dihydroxy-phenyl acetic acid (DOPAC) were determined in 13 healthy volunteers, using high-performance liquid chromatography with an electrochemical detector. In addition, semen analysis was performed. Noradrenaline and DOPA were present in all specimens with a concentration of 15 181+/- 2951 pg ml(-1) and 4023 +/- 429 pg ml(-1) (mean +/- SE), respectively. These concentrations are respectively 19 times (range: 3-44) and twice (range: 1-3) as high as the maximal normal concentration in plasma. Adrenaline was present in 10 and DOPAC in seven of 13 specimens. No correlation was found between the concentration of any of the catecholamines evaluated and semen characteristics. In conclusion, noradrenaline and DOPA are present in human semen at concentrations that are much higher than maximal normal values in plasma. Adrenaline and DOPAC were also found in some of the samples. The concentrations of catecholamines in semen are not associated with semen quality.

Abstract
PURPOSE To assess the comparative efficacy of IVF medium (MediCult, with 5.2 mM glucose) and a glucose/phosphate-free medium, P1 (Irvine Scientific), and to investigate the influence of increasing the serum supplementation (synthetic serum substitute; SSS; Irvine Scientific) to P1 on embryo development and implantation. METHODS Patients were randomly assigned to IVF medium (Group 1, cycles n = 172) or P1 supplemented with 10% SSS (Group 2, cycles n = 229) according to the medium scheduled for use on the day of oocyte retrieval. Another 555 IVF consequent cycles (Group 3) were performed using increased SSS concentrations (20%) in P1 medium. RESULTS AND CONCLUSION In this large series of IVF cycles, we herein demonstrate that significantly higher pregnancy and implantation rates were found when embryos were cultured in glucose/phosphate-free medium P1 supplemented with 20% SSS compared to supplementation with the lower SSS concentration and with IVF medium.

Abstract
Human and rat granulosa cells express receptors to leptin which synergies with glucocorticoid hormones in stimulation of ovarian steroidogenesis. To examine whether leptin affects follicular development and maturation, we injected recombinant ovine leptin (300 ng-10 microg/animal) daily to immature 21 day-old female rats. Non-treated rats reached puberty at 44.5+/-1.6 (n=9) days. In contrast, in leptin treated animals, puberty was reached at 34.5+/-1.6 (n=9) days. Ovarian sections revealed hypertrophy of granulosa cells in leptin treated animals. Moreover, the number of ovulations was 2-fold higher in the treated animals compared to controls (3-4 ovulations versus 7-8 on the first three estrous cycles, P<0.001). Leptin dramatically reduced incidence of follicular apoptosis measured by TUNEL, and was already evident after 7 days of leptin injection (12% of apoptosis in leptin treated group compared to 52% in controls, P<0.001). Maximal protection against apoptosis was achieved at 1-3 microg leptin/animal. The levels of FSH, LH, progesterone and the steroidogenic factors ADX and STAR were elevated earlier in development in the leptin treated animals compared to control animals which is in line with the achievement of early puberty in the leptin treated animals compared to non treated ones. To reveal whether modulation of death and survival genes is involved in leptin attenuation of follicular apoptosis, we examined the expression of the survival gene Bcl-2 and the death gene Bax in Western blots of ovarian homogenates. There was a pronounced elevation in Bcl-2 expression during 7-14 days of leptin injections up to 16.3-fold (P<0.001) compared to Bcl-2 expression in controls. Bax expression was elevated only 3.4 fold (P<0.001), leading to an increase in the Bcl-2/Bax ratio of 4.7 fold (P<0.001). Expression of the tumor suppressor gene p 53 and the oncogene Mdm2 did not change significantly. Our data suggests that leptin may be involved in accelerating follicular maturation by attenuating follicular atresia and increasing the ratio of Bcl-2/Bax.

Abstract
This study examined the correlation between various coping strategies and sexual functioning and the likelihood of conception from in vitro fertilization (IVF). Self-reported questionnaires were distributed randomly among the 102 women enrolled in an IVF program, 96 of whom were recruited. Of the studied parameters, positive reinterpretation, and growth, and active coping strategies were found to be positively associated with sexual functioning, while there was a significantly (p < .05) adverse influence of planning and self-restraint. Being sexually active during the IVF-treatment period was found to be positively associated (p < .05) with the likelihood of conception and with adaptive coping strategies.

Abstract
OBJECTIVES To assess the role of diagnostic urethrocystoscopy in the evaluation of women with idiopathic detrusor instability (DI) refractory to conventional pharmacologic management. METHODS One hundred consecutive women (mean age 62.1 +/- 15.1 years) with idiopathic DI refractory to conventional pharmacologic management were prospectively enrolled. All patients underwent a meticulous evaluation, including a detailed history, urogynecologic questionnaire, micturition diary and pad test, urinalysis and culture, physical examination, and urodynamic studies. Refractory DI was defined as the lack of clinical improvement after at least 6 months of conventional drug therapy. These patients underwent additional evaluation with diagnostic urethrocystoscopy. RESULTS All patients had a normal urinalysis and negative cytologic findings. Diagnostic urethrocystoscopy revealed isolated bladder tuberculosis in one and transitional cell carcinoma in another. Seven other patients had bladder diverticula (only one of which was also diagnosed by sonographic examination) and 22 had mild-to-moderate bladder trabeculations. CONCLUSIONS The absence of other alarming signs (ie, recurrent urinary tract infection, hematuria, significant residual urinary volume, positive cytologic findings, or suspicious sonographic findings) cannot confirm the lack of significant lower urinary tract abnormalities among patients with refractory DI. Diagnostic urethrocystoscopy, a simple and safe office procedure, facilitates timely diagnosis and appropriate treatment for these patients.

Abstract
OBJECTIVES Continent patients with a positive stress test demonstrated on repositioning of severe genitourinary prolapse are considered to be at high risk of developing postoperative symptomatic stress urinary incontinence (SUI). Our aim was to evaluate in a prospective study whether a prophylactic, tension-free vaginal tape (TVT) procedure, performed during prolapse repair, may prevent the development of postoperative SUI in these women. METHODS Thirty consecutive, clinically continent women (mean age 64.5 +/- 9.04 years) with severe genitourinary prolapse and occult SUI were prospectively enrolled. Occult SUI was defined as a positive stress test with repositioning of the prolapse during the preoperative urodynamic studies. All patients had urethral hypermobility; none had intrinsic sphincter deficiency. In addition to genitourinary prolapse repair, these patients underwent concomitant TVT to prevent postoperative SUI. Patients were followed up for at least 1 year. Repeated urodynamic studies were performed at 3 to 6 months postoperatively. The main outcome measures were postoperative SUI, persistent or de novo detrusor instability, and recurrence of prolapse. RESULTS The mean duration of follow-up was 14.25 +/- 3.08 months (range 12 to 24). None of the patients developed postoperative symptomatic SUI. However, three asymptomatic patients (10%) had a positive stress test during their postoperative urodynamic evaluation. Nine patients (30%) had detrusor instability before surgery, which persisted in six (66%) postoperatively. Postoperative de novo detrusor instability was diagnosed in four other patients (13.33%). None of the patients had recurrent urogenital prolapse, nor did they have clinical evidence of bladder outlet obstruction. CONCLUSIONS The preliminary results of TVT as a prophylactic procedure in clinically continent women with severe prolapse and occult SUI are encouraging. Long-term follow-up is required to confirm the durability of these results.

Abstract
The aim of this study was to evaluate the change in the expression of mannose-ligand receptors following a freezing-thawing procedure, in order to assess its impact on sperm capacitation and acrosome reaction. Twenty semen samples were obtained from fertile donors. Sperm samples were divided into two equal volumes. One aliquot was cryopreserved and the other aliquot was incubated at 32 degrees C. After 2 h the frozen sample was thawed and both samples were further incubated at 32 degrees C to allow capacitation. Mannose receptors were examined following 4 and 22 h of incubation using a mannosylated-BSA-FITC probe. The expression of mannose-ligand receptors on the sperm plasma membrane was determined according to the fluorescence pattern: pattern I represents pre-capacitation, pattern II represents capacitated spermatozoa and pattern III represents acrosome-reacted spermatozoa. After 4 h incubation in capacitating medium, the percentages of patterns I, II and III were 90, 7 and 3% for fresh spermatozoa and 89, 8 and 3% for frozen-thawed spermatozoa, respectively (P > 0.05). Following 22 h of incubation, the percentages of patterns I, II and III were 84, 11 and 5 for fresh spermatozoa and 83, 11 and 6% for frozen-thawed spermatozoa, respectively (not significant at P > 0.05). The percentages of patterns II and III in fresh and frozen-thawed spermatozoa were increased by the same magnitude with longer incubation in the capacitating conditions. It was concluded that the freezing-thawing procedure for human spermatozoa does not affect the expression of mannose-ligand receptors and the dynamics of sperm pre-fertilization processes.

Abstract
Obstetric complications, such as severe pre-eclampsia, fetal growth restriction, abruptio placentae, or stillbirth are associated with abnormally elevated second-trimester maternal serum alpha-fetoprotein (MSAFP) and beta subunit of human chorionic gonadotrophin (betahCG). This has been attributed to placental abnormalities. Women with thrombophilias have been shown to have abnormalities of the placenta resulting in adverse pregnancy outcome in these patients. The purpose of the present study was to evaluate whether women with pregnancy complications and inherited thrombophilias have abnormally elevated second-trimester MSAFP or betahCG. Sixty-two women with pregnancy complications were tested for inherited thrombophilias several months after delivery. The thrombophilia group included 29 women with pregnancy complications and an inherited thrombophilia and the control group included 33 other patients without thrombophilia. Patients in the thrombophilia group had a higher median MoM MSAFP compared to the controls (1.337 vs. 1.086, p=0.0516). The incidence of abnormally elevated MSAFP (>2.5 MoM) was also significantly higher in the thrombophilia group compared to controls (21% vs. 3%, p=0.04). Neither the median MoM betahCG nor the incidence of abnormally elevated betahCG were significantly different between the groups. We conclude that second trimester MSAFP, but not betahCG, is abnormally elevated in patients with thrombophilia and obstetric complications.

Abstract
OBJECTIVE To prospectively evaluate morphologic and histopathologic characteristics of placentas from twin pregnancies obtained by assisted reproductive technologies (ART) and non-ART and to evaluate the influence of previous fetal reduction on placental features. STUDY DESIGN Fifty-five placentas from consecutive deliveries of ART-obtained and 50 placentas from consecutive deliveries of non-ART-conceived twin pregnancies were investigated by one pathologist, who was blinded to specimen origins. The patients' demographic and clinical data were also recorded. RESULTS The mean maternal and gestational ages were similar in both groups. ART-obtained pregnancies were associated with an increased incidence of pregnancy complications and lower mean birth weight. Placentas from ART-obtained pregnancies were mostly of the dichorionic type and were thinner, weighed less and had more infarctions as compared to non-ART-conceived pregnancies. Placental characteristics of reduced ART-obtained twin pregnancies were comparable to those of nonreduced ones. The second twin's placenta in all groups weighed less and had a higher incidence of anomalous umbilical cord insertion. CONCLUSION Placentas from ART-obtained twin pregnancies appear to have more pathologic features as compared to those of non-ART-conceived ones. Fetal reduction does not significantly affect the remaining placentas.

Abstract
The aim of the present study was to evaluate the morphology of testicular spermatozoa by 3 different determinants. Sperm cells were obtained and their morphology was evaluated from 27 testicular sperm extraction (TESE) operations, of which 20 men had nonobstructive azoospermia and 7 had obstructive azoospermia. In 17 cases, 2 biopsies were obtained from 2 different locations of the testis. Only mature spermatozoa presenting full-grown tail (tail dimension about 10-fold greater than the head dimension) were counted. Three characteristics of sperm morphology were evaluated: head dimensions, and acrosome and midpiece irregularities. The percentage of sperm cells with normal morphology (considering the 3 characteristics) in specimens from patients with obstructive and nonobstructive azoospermia were 47% +/- 4.6% and 29 +/- 1.8%, respectively (P < .01). The percentage of spermatozoa with normal head dimensions were 76% +/- 3.2% and 63% +/- 2.6% (P > .05), those with normal acrosome were 58% +/- 4.6% and 41% +/- 3.4% (P < .05), and those with normal midpiece were 74% +/- 4.1% and 67% +/- 1.6% (P > .05), in obstructive and nonobstructive azoospermia, respectively. No significant differences were observed in sperm morphology between different locations of the testis. Sperm morphological characteristics were not associated with fertilization rate in intracytoplasmic sperm injection (ICSI). Follicle-stimulation hormone and luteinizing hormone were inversely correlated with normal morphology of testicular spermatozoa (r = -0.49 and r = -0.47, respectively; P < .05). It can be concluded that a relatively high portion of testicular sperm are morphologically normal. The higher rate of normal spermatozoa in obstructive azoospermia compared with nonobstructive spermatozoa suggests that the factors leading to azoospermia may affect testicular sperm morphology. The morphological characteristics of testicular sperm do not affect fertilization rate in ICSI.

Abstract
The objective of this manuscript is to examine the effect of presentation of the first twin and mode of delivery on perintal outcome in twin deliveries. We reviewed all records of twin deliveries at a gestational age of 32 weeks and more from January 1, 1989 to December 31, 1995. Study cases were divided according to the first twin presentation (vertex = group A, nonvertex = group B) and then subdivided according to the planned mode of delivery, vaginal trial of labor (VTOL), and cesarean section (CS). The protocol for group A facilitated an attempt at vaginal delivery and for group B, vaginal delivery was considered as for a singleton fetus in breech presentation. Of 306 pairs of twins, 235 were in group A and 71 in group B. In group A, 219 women (93.2%) were eligible for VTOL, and the remaining 16 underwent CS. Thirty-three group B women were eligible for VTOL (46.5%; p<0.001) and 38 had CS. In group A, of the 219 candidates for VTOL, 199 (90.9%) delivered vaginally and 20 underwent a CS. In group B, of the 33 VTOL candidates 18 (54.5%) delivered vaginally and 15 underwent CS. Neonatal outcome did not differ in relation to the presentation of the first twin or the planned/actual mode of delivery. There were no cases of birth trauma, neurological complications, or perinatal mortality. Trial of vaginal labor is safe in twin deliveries with the first twin in vertex presentation. Provided criteria for vaginal breech delivery are adhered to, this also appears to be a reasonable option in twin deliveries with the first twin in nonvertex presentation.

Abstract
PROBLEM The selectins, a group of cell adhesion molecules, are major mediators of inflammatory, immunologic, and angiogenic reactions. Their possible involvement and levels of the soluble isoform in serum and ascitic fluid of women with ovarian hyperstimulation syndrome (OHSS) were not previously evaluated. METHOD OF STUDY This prospective, case-control study involved 16 women with OHSS. Ten matched women treated by controlled ovarian stimulation and eight healthy women with normal diagnostic laparoscopy served as controls. Serum and peritoneal fluid samples obtained from all subjects were assayed for soluble endothelial selectin (sES) and soluble platelet selectin (sPS) by specific enzyme-linked immunosorbent assay. RESULTS Significantly higher levels of sES (median, 17.1 [9-41] vs 9.3 [2.4 21.3] ng/mL [P = 0.03]) and sPS (median, 23 [13-277] vs 6.5 [1.6-28.7] ng/mL [P = 0.001]) were observed in the peritoneal fluid of women with OHSS than the basal levels of healthy, non-stimulated women. Women with OHSS had significantly lower sES serum levels than those treated by controlled ovarian hyperstimulation without OHSS, while their sPS serum levels were comparable. CONCLUSIONS Ascitic fluid of women with OHSS contains appreciable amounts of soluble selectins, suggesting their ovarian origin and possible involvement in the syndrome.

Abstract
The present study was undertaken to evaluate the efficacy of Stamey bladder neck suspension in preventing post-perative stress urinary incontinence in clinically continent women undergoing surgery for genitourinary prolapse. Thirty clinically continent women with severe genitourinary prolapse were found to have a positive stress test with re-positioning of the prolapse. They all had significant urethrovesical junction hypermobility. In addition to the genitourinary prolapse repair, these patients underwent a prophylactic Stamey procedure to prevent the possible development of post-operative stress urinary incontinence. The mean duration of follow-up was 8+/-4.5 months (range, 3-19 months). Seven (23.30%) patients developed overt post-operative stress urinary incontinence that was confirmed urodynamically. Eleven (36.7%) other patients denied stress incontinence; however, post-operative urodynamics demonstrated sphincteric incontinence. Post-operative complications were uncommon and minor. In conclusion, continent patients with a positive stress test demonstrated on re-positioning of the prolapse during pre-operative urodynamic evaluation are considered to be at high risk of developing post-operative stress urinary incontinence. In these patients, an additional, effective anti-incontinence procedure should be considered during surgical correction of genitourinary prolapse. The Stamey procedure, although simple and safe, does not appear to be the optimal solution to this clinical problem.

Abstract
BACKGROUND Psychological stress induces rapid and long-lasting changes in blood cell composition, implying the existence of stress-induced factors that modulate hematopoiesis. Here we report the involvement of the stress-associated "readthrough" acetylcholinesterase (AChE-R) variant, and its 26 amino acid C-terminal domain (ARP) in hematopoietic stress responses. MATERIALS AND METHODS We studied the effects of stress, cortisol, antisense oligonucleotides to AChE, and synthetic ARP on peripheral blood cell composition and clonogenic progenitor status in mice under normal and stress conditions, and on purified CD34 cells of human origin. We employed in situ hybridization and immunocytochemical staining to monitor gene expression, and 5-bromo-2-deoxyuridine (BrdU), primary liquid cultures, and clonogenic progenitor assays to correlate AChE-R and ARP with proliferation and differentiation of hematopoietic progenitors. RESULTS We identified two putative glucocorticoid response elements in the human ACHE gene encoding AChE. In human CD34+ hematopoietic progenitor cells, cortisol elevated AChE-R mRNA levels and promoted hematopoietic expansion. In mice, a small peptide crossreacting with anti-ARP antiserum appeared in serum following forced swim stress. Ex vivo, ARP was more effective than cortisol and equally as effective as stem cell factor in promoting expansion and differentiation of early hematopoietic progenitor cells into myeloid and megakaryocyte lineages. CONCLUSIONS Our findings attribute a role to AChE-R and ARP in hematopoietic homeostasis following stress, and suggest the use of ARP in clinical settings where ex vivo expansion of progenitor cells is required.

Abstract
The study was conducted to evaluate the results of IUI treatment in a homogenous group with male factor infertility, and to assess the correlation of sperm variables, including sperm morphology by strict criteria, with pregnancy achievement after IUI. A total of 108 couples with no apparent female aetiology for infertility underwent 264 intrauterine insemination treatment cycles. A comparison was made between the sperm variables in two groups in which the achievement of pregnancy differed. The percentage of motile spermatozoa, degree of motility and normal morphology (by strict criteria) were significantly higher in the pregnant group compared with that of the nonpregnant group. A significant difference in pregnancy rates per couple after intrauterine insemination was demonstrated among three groups according to the percentage of sperm morphology, i.e. poor (< 4%), fair (4-14%) or good (> 14%) (11.1%; 36.1% and 50.0%, respectively). Intrauterine insemination is a valid mode of treatment in cases with male infertility, provided that normal morphology by strict criteria is higher than 4%.

Abstract
OBJECTIVE To prospectively evaluate the prevalence, presumed etiologies and clinical implications of persistent postpartum urinary retention in modern obstetric practice. STUDY DESIGN The study population comprised 8,402 consecutive, unselected parturients delivered in a university-affiliated maternity hospital over a one-year period. If a woman was unable to void spontaneously until the third postpartum day despite intermittent use of a Foley catheter, a diagnosis of persistent postpartum urinary retention was established. Patients were treated by insertion of a Foley catheter for up to two weeks and subsequently by a suprapubic catheter. Obstetric data were collected from the hospital records. RESULTS Four patients (0.05% of the study population), aged 29-37 years, developed persistent postpartum urinary retention. Risk factors included vaginal delivery after cesarean section, prolonged second stage of labor, epidural analgesia, and delayed diagnosis and intervention. Urodynamic evaluation, performed on two patients one month after removal of the suprapubic catheter, revealed genuine stress incontinence in one and detrusor instability in another. None had had any lower urinary tract symptoms before pregnancy and delivery. CONCLUSION Persistent postpartum urinary retention in contemporary obstetric practice is rare but may be associated with long-term bladder dysfunction. Early diagnosis and intervention are required to prevent irreversible bladder damage.

Abstract
OBJECTIVE The purpose of this work was to evaluate the ability of testing for high-risk human papillomavirus (HPV) types using the hybrid capture technique to predict the presence of cervical intraepithelial neoplasia (CIN) II,III in patients with repeated atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesion (LGSIL) on Pap smears. METHODS Hybrid capture testing and tissue biopsy were performed on 503 consecutive women with ASCUS or LGSIL on repeated Pap smears who were referred for colposcopy. RESULTS A highly significant association (P < 0.0001) was found between a positive test for high-risk HPV types and CIN II,III, with an 87.0% positive predictive value and a 95.7% negative predictive value. In 226 women with ASCUS on repeated Pap smears, a positive test for high-risk HPV types had a 85.7% sensitivity and a 97% specificity for CIN II,III. In 277 patients with LGSIL on repeated Pap smears, a positive test for high-risk HPV types had an 88.2% sensitivity and a 94.7% specificity for CIN I,II. Reserving colposcopy examination for women who were positive for high-risk HPV types would have reduced the number of referrals for colposcopy to 24.6% and maintained a sensitivity of 87.0% for CIN II,III. CONCLUSIONS A positive hybrid capture test for high-risk HPV types was highly sensitive and specific for the presence of CIN II,III in patients with ASCUS and LGSIL on repeated Pap smears. We believe that improved methodology will eventually enable more selective colposcopy referrals without affecting patient safety among these women.
