Abstract
OBJECTIVE Fetal twin-twin transfusion syndrome (TTTS) presenting in the second trimester has been associated with almost no perinatal survival until recently, when serial drainage of amniotic fluid has improved the prognosis to 70%-80%. Most recipient twins now survive but develop cardiac dysfunction. The study was undertaken to evaluate the abnormal echocardiographic features and clinical complications of cardiac disease in the recipient twin of TTTS. DESIGN Antenatal and postnatal echocardiographic and clinical observational study. SETTING Antenatal studies in a tertiary referral centre. Postnatal management and follow up were performed by the same paediatric cardiologist, either at the obstetric hospital or at the regional referral centre. PATIENTS Twin pregnancies complicated by TTTS with severe polyhydramnios diagnosed earlier than 25 weeks that proceeded until viability (n = 5). INTERVENTION Serial fetal echocardiography with colour Doppler. Postnatal echocardiography in the first week and between two and seven months. Serial amnioreduction was performed in all pregnancies. Digoxin treatment, pericardiocentesis, paracentesis, or laser ablation of placental anastomoses was undertaken when there was hydrops. RESULTS Increased cardiothoracic ratio and tricuspid regurgitation were seen in all recipient twins. High pulmonary artery velocities developed in three. One recipient twin died a week after delivery of endocardial fibroelastosis and infundibular pulmonary stenosis. Two other had balloon dilatation for pulmonary stenosis, one shortly after birth and one at four months. A further twin has apical thickening of the right ventricle at six months. The remaining recipient twin had normal echocardiographic findings at follow up. CONCLUSION This report characterises for the first time a cardiac disease acquired in utero in the recipient twin in pregnancies complicated by TTTS. Clinical manifestations in utero range from mild to critical pulmonary stenosis or lethal cardiomyopathy. Although perinatal prognosis seems to be related to the severity of dysfunction when first diagnosed in utero, follow up in infancy is recommended in view of the possibility of progressive pulmonary stenosis.

Abstract
Old, middle-aged, and young dogs were compared on discrimination and reversal learning and on acquisition of a delayed-nonmatching-to-sample (DNMS) test of recognition memory. DNMS acquisition was acquired more rapidly by young dogs. Reversal deficits were found between aged mixed-breed dogs and young beagles, but not between old and young beagles. Aged beagles also showed unexpected deficits in reward approach and object approach learning. Aged mixed-breed dogs did not show deficits in reward approach and object approach learning, but they learned the discrimination task more slowly than the age-matched beagles. A detailed analysis of response patterns indicated that once present, the development of side preferences contributed to deficits of old dogs in discrimination learning. In the discrimination reversal, old dogs were more persistent in responding to the previously rewarded stimulus object. Findings suggest that the dog, like other species, shows age-dependent deterioration in cognitive function, the extent of deterioration is a function of both task and previous experience, and at least part of the deterioration is a result of increased behavioral rigidity. Results also indicate that it is important to control for breed differences and previous experience.

Abstract
Some nonsteroidal anti-inflammatory drugs (NSAIDs), including cyclooxygenase-2 selective inhibitors, have been associated with increased cardiovascular (CV) events in recent clinical trials or observational studies. To determine whether the cyclooxygenase-2 selective inhibitor celecoxib affects CV risk, the incidence of CV events was analyzed in patients treated with celecoxib, placebo, or nonselective NSAIDs in the clinical trial database for celecoxib using defined Antiplatelet Trialists' Collaboration end points of nonfatal myocardial infarction, nonfatal stroke, and CV death. Patient data were derived from studies in osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, low back pain, and Alzheimer's disease. This meta-analysis included (1) 7,462 patients exposed to celecoxib 200 to 800 mg/day for 1,268 patient-years compared with 4,057 patients treated with placebo for 585 patient-years, and (2) 19,773 patients treated with celecoxib 200 to 800 mg/day for 5,651 patient-years compared with 13,990 patients treated with nonselective NSAIDs (diclofenac, ibuprofen, naproxen, ketoprofen, and loxoprofen) for 4,386 patient-years. CV events were adjudicated by a 3-member expert end point committee (WBW, JSB, PBG) blinded to treatment group and study. The incidence rates of the combined CV events were not significantly different between patients treated with celecoxib and placebo or between those treated with celecoxib and nonselective NSAIDs. Event rates were similar for adjudicated and nonadjudicated data. Dose of celecoxib, the use of aspirin, or the presence of CV risk factors did not alter these results. In conclusion, these analyses failed to demonstrate an increased CV risk with celecoxib relative to placebo and demonstrated a comparable rate of CV events with celecoxib treatment compared with nonselective NSAIDs.

Abstract
OBJECTIVE To compare perinatal outcome and glycaemic control in two groups of pregnant diabetic patients receiving two insulin regimens. DESIGN Randomised controlled open label study. SETTING University affiliated hospital, Israel. PARTICIPANTS 138 patients with gestational diabetes mellitus and 58 patients with pregestational diabetes mellitus received insulin four times daily, and 136 patients with gestational diabetes and 60 patients with pregestational diabetes received insulin twice daily. INTERVENTION Three doses of regular insulin before meals and an intermediate insulin dose before bedtime (four times daily regimen), and a combination of regular and intermediate insulin in the morning and evening (twice daily regimen). MAIN OUTCOME MEASURES Maternal glycaemic control and perinatal outcome. RESULTS Mean daily insulin concentration before birth was higher in the women receiving insulin four times daily compared with twice daily: by 22 units (95% confidence interval 12 to 32) in patients with gestational diabetes and by 28 units (15 to 41) in patients with pregestational diabetes. Glycaemic control was better with the four times daily regimen than with the twice daily regimen: in patients with gestational diabetes mean blood glucose concentrations decreased by 0.19 mmol/l (0.13 to 0.25), HbA(1c) by 0.3% (0.2% to 0.4%), and fructosamine by 41 micromol/l (37 to 45), and adequate glycaemic control (mean blood glucose concentration <5.8 mmol/l) was achieved in 17% (8% to 26%) more women; in patients with pregestational diabetes mean blood glucose concentration decreased by 0.44 mmol/l (0.28 to 0.60), HbA(1c) by 0.5% (0.2% to 0.8%), and fructosamine by 51 micromol/l (45 to 57), and adequate glycaemic control was achieved in 31% (15% to 47%) more women. Maternal severe hypoglycaemic events, caesarean section, preterm birth, macrosomia, and low Apgar scores were similar in both dose groups. In women with gestational diabetes the four times daily regimen resulted in a lower rate of overall neonatal morbidity than the twice daily regimen (relative risk 0.59, 0.38 to 0.92), and the relative risk for hyperbilirubinaemia and hypoglycaemia was lower (0.51, 0.29 to 0.91 and 0.12, 0.02 to 0.97 respectively). The relative risk of hypoglycaemia in newborn infants to mothers with pregestational diabetes was 0.17 (0.04 to 0.74). CONCLUSIONS Giving insulin four times rather than twice daily in pregnancy improved glycaemic control and perinatal outcome without further risking the mother.

Abstract
OBJECTIVE To investigate the relationships between serum and urinary molecular markers (MM) used to monitor osteoarthritis. DESIGN Forty osteoarthritis patients had blood and urine collected at baseline and 1, 3, 6 and 12 months later. Specimens from 20 controls were obtained twice at a one month interval. The concentration of 14 different markers was determined at each time point and the data were analyzed by statistical methodology. RESULTS The markers could be divided by the method of principal components analysis into five clusters of related markers: inflammation markers (C-reactive protein, tumor necrosis receptor type I and tumor necrosis receptor type II, interleukin 6, eosinophilic cationic protein), bone markers (bone sialoprotein, hydroxylysyl pyridinoline, lysyl pyridinoline), putative markers of cartilage anabolism (carboxypropeptide of type II procollagen, hyaluronan, epitope 846) and catabolism (keratan sulfate, cartilage oligomeric matrix protein), and transforming growth factor beta. Three markers (tumor necrosis factor receptor II, cartilage oligomeric matrix protein and epitope 846) from independent clusters discriminated osteoarthritis patients from controls. Inflammation was not a confounding factor in measurement, but a recognizable distinguishing factor in osteoarthritis. CONCLUSIONS The markers separated into rational groups on the basis of their covariance, a finding with independent biochemical support. The covariance of markers from the same cluster suggests the use of a representative marker from the cluster to reflect changes in osteoarthritis. If multiple markers are being measured within a single cluster, then the use of a weighted cluster 'factor' may be preferable to the separate use of individual markers.

Abstract
The binding of different synthetic steroids, used in hormonal contraception, to Sex Hormone Binding Globulin (SHBG) was studied by measuring their ability to displace tritiated testosterone from SHBG in a competitive protein binding system. Only 19-nortestosterone derivates had any significant ability to displace testosterone from SHBG, d-norgestrel (d-Ng) being the strongest displacer. Increasing the SHBG levels in women with previous constant plasma d-Ng levels increased these levels two- to sixfold. It is concluded that SHBG is the main carrier protein for d-Ng. The strong testosterone displacing activity of d-Ng might also explain androgenic side effects observed with d-Ng containig oral contraceptives.

Abstract
OBJECTIVE To evaluate the efficacy of transvaginal sonography and serum beta-hCG levels as diagnostic tools for deciding whether to perform operative laparoscopy in the treatment of presumed ectopic pregnancy (EP). DESIGN A prospective protocol for the evaluation and treatment of women with presumed EP. SETTING Department of Obstetrics and Gynecology, Haemek Medical Center, Afula, Israel. PATIENT(S) Eight hundred forty women with presumed EP who were seen in our emergency department from January 1988 through December 1995. INTERVENTION(S) On the basis of specific sonographic signs and beta-hCG levels, we performed immediate operative laparoscopy in patients with demonstrable extrauterine fetal heart activity or >100 mL of fluid in the pelvic cavity. We followed up all other patients, using defined criteria for laparoscopic intervention. MAIN OUTCOME MEASURE(S) The accuracy of transvaginal sonography in predicting EP was evaluated as part of the described protocol. RESULT(S) Overall, 380 patients were found to have EP. Of these, 331 were identified positively by transvaginal sonography and 49 were not. In 27 of 358 laparoscopies, no EP was found. The sensitivity of transvaginal sonography for the prediction of EP was 87% and the specificity was 94%. The positive and negative predictive values were 92.5% and 90%, respectively. CONCLUSION(S) In this protocol, which invariably captured the true location of the products of conception, using transvaginal sonography as the primary modality in the evaluation of patients with presumed EP resulted in the use of laparoscopy mainly as a treatment tool. This approach is both safe and economical.

Abstract
To compare and assess ingestion of yogurt that contained live Lactobacillus acidophilus with pasteurized yogurt as prophylaxis for recurrent bacterial vaginosis (BV) and candidal vaginitis, we designed a crossover trial during which patients were examined monthly for candidal infection and BV while they were receiving either a pasteurized yogurt or a yogurt that contained live L acidophilus. Forty-six patients in 2 groups of 23 were randomly assigned to each of the study groups. At least 28 (61%) participated during the first 4 months of the study. Seven patients completed the entire study protocol. We concluded that daily ingestion of 150 mL of yogurt, enriched with live L acidophilus, was associated with an increased prevalence of colonization of the rectum and vagina by the bacteria, and this ingestion of yogurt may have reduced episodes of BV.

Abstract
PURPOSE Patients with primary pulmonary hypertension (PPH) frequently have Raynaud's phenomenon, serum antinuclear antibodies (ANAs), and/or pulmonary vascular lesions similar to those seen in certain connective tissue diseases, especially scleroderma. A number of relatively disease-specific autoantibodies have been described in connective tissue diseases but have not been studied in patients with PPH. Therefore, sera from PPH patients were studied for a variety of autoantibodies, seeking a possible link between this pulmonary disorder and connective tissue diseases. PATIENTS AND METHODS Sera from 31 patients with PPH and 24 with secondary pulmonary hypertension (SPH) were studied for the following autoantibodies: anti-centromere (indirect immunofluorescence of Hep-2 cells), anti-CENP-B by immunoblotting and enzyme immunoassay (EIA) using cloned CENP-B fusion protein, anti-topoisomerase I (Scl-70), anti-Ku using immunoblotting of affinity purified antigens, anti-cardiolipin using EIA, and anti-Ro (SS-A), La (SS-B), Sm, nRNP, Jo-1, PM-Scl, and Mi-2 by counter-current immunoelectrophoresis. RESULTS Anti-Ku antibodies were found in 23% of patients with PPH, 4% with SPH, and none of 24 normal controls (PPH versus SPH, p = 0.06: PPH versus controls, p = 0.01). Antibodies to CENP-B were found in one patient each with PPH and SPH, anti-topoisomerase I in one with SPH, and anti-Ro (SS-A) and La (SS-B) in one with PPH. Overall, 12 patients (39%) with PPH had Raynaud's phenomenon or positive ANA results, with 9 (29%) having more specific autoantibodies associated with connective tissue diseases. CONCLUSIONS These results further suggest a link between at least a subgroup of patients with PPH and autoimmune connective tissue diseases, with anti-Ku antibodies being a possible new serologic marker.

Abstract
OBJECTIVE The study examined the efficacy, tolerability, and safety of supportive group psychotherapy and adjunctive sustained-release bupropion for nicotine addiction in patients with schizophrenia. METHOD Eight patients participated in a 14-week open-label trial. End expired breath carbon monoxide level, symptom levels, neuropsychological performance, and suppression of the P50 event-related potential were measured before and after the 14-week trial. RESULTS Patients showed a decrease in carbon monoxide levels that was not associated with any worsening in symptom, neuropsychological, or P50 suppression measures. CONCLUSIONS Use of sustained-release bupropion in combination with supportive group therapy may help patients with schizophrenia decrease their cigarette consumption.

Abstract
OBJECTIVES To evaluate bipolar diathermy as a technique for selective fetocide in the treatment of advanced (Stage III/IV) twin-twin transfusion syndrome (TTTS). METHODS A prospective observational study in two tertiary referral fetal medicine centres: Queen Charlotte's Hospital, London, UK and Haemek Hospital, Afula, Israel. Fifteen cases of TTTS (14 twins and one triplet pregnancy) were treated by selective occlusion of either the donor (n=8) or recipient's (n=7) umbilical cord using ultrasound-guided bipolar diathermy. Following each procedure, patients were scanned serially for fetal growth, liquor volume and umbilical Doppler measurements. Procedural complications and obstetric outcome were recorded. Postnatal placental injection studies were performed. RESULTS Overall co-twin survival in Stage III/IV TTTS was 13/14 (93%). There were no treatment failures. The incidence of preterm prelabour rupture of membranes (PPROM) within 3 weeks of the procedure was 3/15 (20%). In those cases where pre-procedure umbilical artery Dopplers were abnormal, the Doppler findings normalised post-procedure in all non-cord-occluded fetuses. Growth velocities of surviving donors were similar to those of surviving recipients. CONCLUSIONS Bipolar diathermy appears an effective technique for the selective reduction of monochorionic twins complicated by severe as well as preterminal TTTS, with recipient and donor fetuses being equally appropriate choices for fetocide. We suggest that for advanced-stage disease where the parents can contemplate this option, cord occlusion as a single preemptive procedure maximises the opportunity for intact survival of a single survivor.

Abstract
OBJECTIVE To investigate whether any of 14 serum and urine molecular markers (MMs) used to monitor osteoarthritis (OA) would be associated with particular clinical end-points. DESIGN Thirty-nine OA patients were bled and urine collected at five time points: at baseline visit and at visits 1, 3, 6 and 12 months later. Twelve clinical measurements were made and the concentrations of each of 14 MMs were determined. Principal component analysis, stepwise linear regression with backward elimination, and logistic regression were used to determine the correlations between MMs and clinical measures. RESULTS Principal component analysis was used to reduce the 12 clinical measurements into three independent clinical clusters: baseline clinical assessments, changes in clinical assessments and signal joint measurements. The 14 MMs were similarly reduced to five MM clusters. Each of the three clinical clusters was correlated with a single but different MM cluster. Baseline clinical assessments were correlated with bone markers typified by hydroxylysyl pyridinoline (HP) crosslinks, swelling of the signal joint was correlated with inflammation markers, especially CRP, and the change in clinical assessments over the 1 year evaluation was correlated with TGFbeta1. There was no correlation between any of the skeletal markers and the clinical measures, a situation which draws attention to the need for a direct assessment of cartilage damage in OA to validate the use of cartilage markers. CONCLUSIONS This study demonstrates statistical methodology for analysis of clinical trials using multiple MMs and clinical end-points. The patient numbers are sufficient to test hypotheses of relationships of single MMs such as CRP, TGFbeta1 and HP to clinical measures, but larger clinical trials are needed to validate hypotheses.

Abstract
A solid-phase enzyme-linked immunosorbent assay has been established using a cloned fusion protein, CtermCENP-B [beta-gal], as antigen. The fusion protein carries the major epitope of CENP-B, the major centromeric autoantigen. The enzyme-linked immunosorbent assay was more sensitive than immunofluorescence techniques in detecting anticentromere antibodies in patients with scleroderma or Raynaud's disease, and was weakly positive in 3% of normal controls and in 3% of 70 patients with other connective tissue diseases.

Abstract
Nonsteroidal anti-inflammatory drugs have been a mainstay in the treatment of inflammatory diseases such as rheumatoid arthritis. However, these agents can result in severe and occasionally life-threatening adverse effects that can limit therapeutic benefit. Progress toward safer anti-inflammatory therapy was aided by the discovery that cyclooxygenase (COX) exists as two isozymes, COX-1 and COX-2. Both isozymes form prostaglandins that support physiologic functions; however, the formation of proinflammatory prostaglandins is catalyzed by COX-2. Inhibition of COX-2 accounts for the anti-inflammatory and analgesic action of NSAIDs; however, concurrent inhibition of COX-1 inhibits prostaglandin-dependent mechanisms such as gastroduodenal mucosal defense and platelet aggregation. This inhibition is the basis of the gastrointestinal toxicity and bleeding characteristic of these drugs. These findings led to the hypothesis that agents that selectively inhibit COX-2 would possess anti-inflammatory and analgesic action but would spare COX-1, thereby avoiding adverse effects in the gastrointestinal tract and platelets. Selective COX-2 inhibitors are now available. The novelty of these agents has raised questions in the medical community as to what constitutes selectivity for COX-2. This review outlines the criteria that must be met to characterize a compound as COX-2-specific. Clinical evidence of clear improvement in gastrointestinal tolerability and safety must be demonstrated in addition to complementary evidence of COX-2 selectivity obtained from enzyme, biochemical, and clinical pharmacology evaluations.

Abstract
An RIA for a new progestin, ST-1435, was developed. Plasma concentrations of this steroid were measured in three women having three subcutaneous capsules, each containing 40 mg of ST-1435. Pituitary and ovarian functions were assessed by measuring plasma levels of LH, FSH, estradiol and progesterone. Plasma profiles of ST-1435 were characterized by high and irregular peaks all the way through the study period of 7-9 months. Concentrations below 100 pg/ml were not observed, whereas the highest peaks reached concentrations of 10.1 ng/ml. Plasma estradiol concentrations remained uniformly suppressed below 100 pg/ml, thus indicating a suppression in follicle development. As judged by constantly suppressed progesterone concentrations, no ovulations occurred during the treatment. Plasma FSH concentrations remained at the upper limit of the follicular phase, and those of LH at the lower limit of the luteal phase of the normal menstrual cycle. No midcycle gonadotropin peaks were observed.

Abstract
A case of conjoined twins in a triplet pregnancy after in-vitro fertilization and intracytoplasmic sperm injection is described. The diagnosis was made by high-resolution vaginal sonography, as early as the eighth week of gestation. The third fetus, of different chorionicity, was normal. Selective termination was successfully done at 12 weeks. The possible association between assisted reproduction and conjoined twinning is discussed. The importance of expert early vaginal sonography of pregnancy resulting from assisted reproduction technology is emphasized.

Abstract
Prenatal real-time ultrasonographic diagnosis of microphthalmia is presented. Diagnosis was made at 18 weeks' gestation in a fetus of a patient with a previous infant affected with the syndrome of cryptophthalmia with absence of septum nasi and ambiguous genitalia (Fraser syndrome). Recognition of microphthalmia as a part of Fraser syndrome and the easy visualization of fetal facial bones and orbits in the second trimester made the diagnosis possible.

Abstract
Methotrexate peak level after intratubal injection was found to be significantly lower than the accepted toxic level. After IM injection, MTX peak level and the AUC were found to be similar to the levels observed after intratubal injection. The advantage of tubal injection over IM injection is challenged.

Abstract
We studied the expression of IgG, IgM, and IgA autoantibodies in the anti-topoisomerase I and anticentromere immune responses by enzyme-linked immunosorbent assay, immunoblotting, and immunofluorescence. While IgG autoantibodies were most common, IgA autoantibodies were also frequently found, but IgM autoantibodies were rare. This is the first report of IgA autoantibodies in scleroderma.

Abstract
In order to investigate the effect of changes in sex hormone binding globulin (SHBG) levels on d-norgestrel (d-Ng) levels in plasma, the plasma levels of SHBG and d-Ng were studied during one treatment cycle in 6 women on oral contraceptives containing d-Ng and ethinyloestradiol (EOE2) and in 3 women using subcutaneous silastic rods containing d-Ng concomitantly taking EOe2 for three weeks. A significant positive correlation between the SHBG and d-Ng levels was found in 7 of the 9 subjects studied. The results provide evidence for an in vivo binding of d-Ng to SHBG, a SHBG influence on the metabolic clearance rate of d-Ng and consequently a dependence of the plasma levels of d-Ng on the SHBG concentrations in the plasma. These findings support the concept that the clinically and biochemically observed anti-oestrogenic/androgenic effects observed in women on d-Ng containing medication are due to a displacement of testosterone from SHBG by d-Ng.

Abstract
Pretreatment serum levels of the antigens CA-125, tissue polypeptide Antigen (TPA), carcinoembryonic antigen (CEA), and placental alkaline phosphatase (PLAP) were determined in samples from 295 women with adnexal masses. At laparotomy 48% of patients had epithelial ovarian carcinoma, 9% had tumors of low malignant potential, and 8% suffered from malignancies of other kinds. The sensitivity of CA-125 with 35 U/ml as the cutoff was 88% in women with ovarian carcinoma, but 74% among those with limited disease and 58% in borderline malignancy. Only 6 of 17 mucinous ovarian carcinomas were detected. Specificity was 83%. CEA was elevated above 5.0 micrograms/liter in 15 of 17 patients with mucinous ovarian cancer. TPA detected advanced stages of malignancy, but the sensitivity was low, 53%, in cases with limited disease. PLAP was elevated in 46% of ovarian carcinoma patients. For detecting malignancy overall, the use of a parallel combination of the CA-125 and CEA assays was more sensitive than use of CA-125 as a single marker. This test combination may be of value in the diagnosis of adnexal masses. The predictive value of a positive result was 90%, and that of a negative result, 76%.
