Background: Galactin-3 has been found to be involved in oocyte maturation, folliculogenesis, implantation, and placentation. The expression of Galactin-3 in the endometrium of women who have successfully undergone in vitro fertilization (IVF) has been suggested as a potential biomarker for predicting successful embryo implantation.

Objectives: To evaluate the expression of Galactin-3 in the sera and follicular fluid of women during IVF cycles.

Methods: This prospective research included 21 women undergoing IVF treatments. Blood samples were taken at four points: day 2 before starting stimulation, trigger day, day of oocyte retrieval, and day of the β-human chorionic gonadotropin level test. In addition, follicular fluid samples were taken on the day of oocyte retrieval. Galactin-3 protein levels were measured in serum and follicular fluid using enzyme-linked immunosorbent assay.

Results: Galactin-3 levels on the stimulation day were positively correlated to estradiol levels on the day of the trigger (0.59, P = 0.02). Among women who achieved pregnancy compared to those who did not, Galectin-3 serum levels were higher on the day of the trigger (17.93 ± 4.35 ng/ml vs. 11.01 ± 3.73 ng/ml, P = 0.015).

Conclusions: These findings may imply a potential role of Galectin-3 on the success of IVF treatments, underscoring the potential importance of inflammatory processes in fertility.

Background: Removal of retained placental tissue postpartum and retained products of conception (RPOC) abortion is done by uterine curettage or hysteroscopy. Trauma to the endometrium from surgical procedures, primarily curettage, can cause intrauterine adhesions (Asherman's syndrome) and subsequent infertility. The incidence of malpractice claims relating to intrauterine adhesions is rising, justifying reevaluation of the optimal way of handling these complications. 

Objectives: To review malpractice claims regarding intrauterine adhesions, and to explore the clinical approach that might reduce those claims or improve their medical and legal outcomes.

Methods: We examined 42 Asherman's syndrome claims handled by MCI, the largest professional liability insurer in Israel. The clinical chart of each case was reviewed and analyzed by the event preceding the adhesion formations, timing and mode of diagnosis, and outcome. We also assessed whether the adverse outcome was caused by substandard care and it it could have been avoided by different clinical practice. The legal outcome was also evaluated.

Results: Forty-seven percent of the cases occurred following vaginal delivery, 19% followed cesarean section, 28% were RPOC following a first-trimester pregnancy termination, and 2% followed a second-trimester pregnancy termination.

Conclusions: It is apparent that due to a lack of an accepted management protocol for cases of RPOC, it is difficult to legally defend those cases when the complication of Asherman syndrome develops.

Background: Although the comprehensive evaluation of the fetal heart includes echocardiography by an experienced pediatric cardiologist, economic constraints sometimes dictate the need to select patients.

Objectives: To analyze the usefulness of fetal echocardiography in the detection of congenital heart disease according to the referral indication.

Methods: This retrospective survey relates to all 3965 FE studies performed in our center from January 2000 to December 2004. The diagnosed cardiac anomalies were classified as significant and non-significant malformations. All FE[1] studies were done by a single operator (A.L.) at Meir Medical Center, a referral center for a population of about 400,000. The 3965 FE studies were performed for the following indications: abnormal obstetric ultrasound scans, maternal and family history of cardiac malformations, medication use during the pregnancy, and maternal request. The relative risk of detecting CHD[2] was calculated according to the various referral indications.

Results: Overall, 228 (5.8%) cases of CHD were found. The most common indication for referral was suspicion of CHD during a four-chamber view scan in a basic system survey or during a level II ultrasound survey. No correlation was found between maternal age and gestational age at the time of scanning and the likelihood of finding CHD.

Conclusions: Our data suggest that a suspicious level-II ultrasound or the presence of polyhydramnios is an important indication for FE in the detection of significant CHD.

 Background: During maintenance hemodialysis acute elevation in serum calcium is common. Low calcium dialysis is advocated as a therapy for prevention of dialysis-induced hypercalcemia. Approximately 16% of our chronic hemodialysis patients experience elevated arterial blood pressure during the hemodialysis session, becoming hypertensive by the end of the treatment. All these patients exhibited post-dialysis hypercalcemia.

Objectives: To investigate the effect of low calcium dialysis on post-dialysis hypertension in view of an evident link between serum calcium and blood pressure in both normal renal function and chronic renal failure patients.

Methods: We evaluated 19 chronic hemodialysis patients in whom both post-dialysis hypertension and PDHCa[1] were observed. We investigated changes in serum total calcium, ionized calcium, intact parathormone levels and arterial blood pressure in response to 4 weeks low calcium dialysis as a treatment for PDHCa.

Results: When PDHT[2] patients were treated with low calcium dialysis, post-dialysis blood pressure was significantly decreased compared to pre-dialysis values (155.3 ± 9.7/82.2 ± 7.9 mmHg pre-dialysis vs. 134.1 ± 20.8/80 ± 8.6 mmHg post-dialysis, P = 0.001). Additionally, post-dialysis blood pressure was significantly lower than post-dialysis blood pressure prior to the low calcium dialysis treatment (176.1 ± 15/86 ± 10.8 mmHg post-standard dialysis, 134.1 ± 20.8/80 ± 8.6 mmHg after low calcium dialysis, P = 0.001). A decline in post-dialysis serum calcium (2.34 ± 0.2 vs. 2.86 ± 0.12 mmol/L, P = 0.04) and ionized calcium (1.17 ± 0.12 vs. 1.3 ± 0.06 mmol/L, P = 0.03) compared to pre-dialysis levels was also achieved by this treatment, with no significant changes in iPTH[3] levels.

Conclusions: These data suggest a role for low calcium dialysis in treating acute serum calcium elevation and post-dialysis hypertension in patients receiving maintenance hemodialysis.

Background: Previous studies have documented an increased incidence of cardiac mortality and sudden death during winter months.

Objectives: To evaluate seasonal variation in sudden death in a hot climate such as the desert region of southern Israel.

Methods: We analyzed the files of 243 consecutive patients treated for out-of-hospital sudden death by the Beer Sheva Mobile Intensive Care Unit during 1989-90. Daily, monthly and seasonal incidence of sudden death was correlated with meteorological data, including temperature, heat stress, relative humidity and barometric pressure.

Results: The seasonal distribution of sudden death was 23% in spring, 21% in summer, 25% in autumn and 31% in winter (not significant). In patients with known heart disease there were more episodes of sudden death in cold weather (<15.4°C) than hot (>34.2°C) (16 vs. 3, P<0.05). Resuscitation was less successful in cold compared with hot weather (28 vs. 11, P<0.05). Of patients older than 65 years, 11 sustained sudden death when heat stress was below 12.4°C compared to 2 patients when heat stress was above 27.5°C (P=0.05).

Conclusion: Despite the warm desert climate, there were more cases of sudden death in older patients and in those with known heart disease during the winter season and on particularly cold days.
