Committee of the Israel National Registry Assisted Reproductive Technologies*

National registration of the results of assisted reproductive technology (ART) is maintained by many countries. The Israel Committee for Registry of ART asked 19 in-vitro fertilization (IVF) units in 1995 and 20 in 1996 to report on their activities and results.

Data were collected by questionnaires and analyzed by computer. The most common ovarian stimulation was the combination of GnRH agonist and gonadotropins. There were 10,89 treatment cycles in 1995, of which 45% were with intracytoplasmic sperm injection (ICSI). In 1996, of 12,72 cycles, 54% were with the ICSI procedure. Embryos were transferred into the uterine cavity in 90% of the conventional IVF cycles and in 95% of the ICSI cycles. The overall pregnancy rate was 22% per embryo transfer in the conventional IVF and ICSI cycles. The delivery rate was 13.7% and 15.4% per embryo transfer in the conventional IVF and ICSI cycles, respectively. The rates for abortion and tubal pregnancy were 24% and 1.3%, respectively.

These results are better than in previous years and are comparable with results in some western European countries. Efforts are being made to convert the registry into a real-time computerized system.

Spina bifida and anencephaly are the most common, serious malformations in neural tube defects (NTD). Randomized trials in the last 2 decades have demonstrated that folic acid, 0.4 mg/d, reduces the incidence of NTD by more than 50%. We investigated the use of folic acid and multivitamins containing folic acid in childbearing women.

Of 221 women interviewed, 67 (30%) regularly took pills containing 0.4 mg folic acid. Women with higher educational levels were more likely to take multivitamins with folic acid than were the less educated (p=0.05). Of the women who took folic acid, only 5 (7.5%) used separate folic acid tablets, before and during their pregnancy. The rest used multivitamins containing folic acid. The 5 women who took folic acid separately were college-educated and nonreligious, and they took multivitamins in addition (p>0.05).

Of the women interviewed, 58 (26.2%) were Bedouin of the Negev. 24 (41.4%) of them took pills containing folic acid on a regular basis. This percentage is higher than that in the Jewish women in the study who took folic acid for prevention of NTD (17%; p=0.038).

Most of the women took folic acid after the first trimester. Only a minority took daily periconceptional folic acid. Multivitamins containing 0.4 mg of folic acid were more popular than folic acid tablets alone. This study emphasizes the need for continuing efforts to increase consumption of folic acid and awareness of its benefits among women of childbearing age.

Medical malpractice suits in obstetrics comprise about 10% of all claims against medical institutions in Israel. A significant proportion are due to failures relating to fetal monitoring. We studied the characteristics of 102 of 4125 obstetrical cases reported to the Medical Risk Management Co. as being at risk for a malpractice suit.

The cases were divided into those with medical management failures (misinterpretation of fetal monitor tracing, failure to respond promptly to fetal monitoring indicating distress, etc.) and technical failures (loss of monitor tracings, interruption in the tracing at a critical time, unreadable tracings, etc.).

The monetary quantum in fetal monitoring failures exceeded $30,000,000. The majority of these failures could have been avoided by using central electronic fetal monitoring systems with alerting and archival capabilities.

350 patients attending 11 large out-patient clinics completed questionnaires evaluating attitudes to, and experience with complementary medicine. 129 (36%) respondents reported using complementary medicine. 14% of them used complementary medicine for the current medical problem for which they were attending the clinic.

Pain was the most common medical problem for which complementary medicine was used, followed by respiratory problems and cancer. Common therapeutic modalities used were acupuncture, homeopathy, nutrition and herbal medicine.

Women, the secular as opposed to the religious, and those with higher education were more apt to use complementary medicine. No differences were found in age, national origin, length of living in Israel, and diet (vegetarian, natural foods or regular diet) between those who used complementary medicine and those who did not. No relationship was found between the use of complementary medicine and perceived poor health status, locus of control, or satisfaction with the doctor-patient relationship.

Testicular cancer is the most common malignancy in young men. To evaluate knowledge and awareness of that cancer, and of the practice of testicular self-examination (TSE), we developed a questionnaire which was distributed to 717 male soldiers and 200 of their military physicians.

21% of the soldiers had received some explanation of the importance of TSE, but only 16% were actually instructed how to perform TSE, and only 2% practiced it regularly. 24% had never examined their testicles before, 185 only rarely, and 6% often. With increased age, TSE frequency increased, but previous education, type of military unit, and ethnic origin had no affect. 99% of military physicians had been taught how to examine breasts, but only 70% had been taught routine testicular examination. 22% performed it, but 27% never did. 84% had never taught their soldiers the importance of TSE, although 51% taught female soldiers breast self-examination.

There was a significant lack of awareness of the importance of regular practice of TSE among both soldiers and their army physicians.

Gastrointestinal bleeding of obscure origin consists of recurrent bouts of acute or chronic bleeding for which no definite source is discovered in routine endoscopic and barium contrast studies of the upper and lower gastrointestinal tracts. Usually its cause is angiodysplasia of the intestine, but many cases are due to tumors, mostly of the small bowel, which may be malignant.

In patients under the age of 50, the proportion with malignancy is relatively high (up to 14%) as compared to older patients. We describe a 45-year-old woman who suffered from gastrointestinal bleeding for 3 years. The cause of bleeding was not found despite extensive work-up.

In her last admission for acute gastrointestinal hemorrhage she was given a total of 30 units of blood. A tumor of the small intestine found by angiography was excised and found to be a stromal tumor of uncertain malignant potential. 1 year after operation she is asymptomatic without bleeding and her hemoglobin is stable without treatment.

We examined all ceftriaxone-resistant Escherichia coli isolates obtained from clinical samples during 16 months (1‚Dec. '97 - 31 Mar. '99). A total of 97 resistant isolates from 36 patients were obtained, mostly from urine specimens. Of these patients, 35/36 were over 75 years old, most lived in nursing homes, were dependent on nursing in their daily lives, and were incontinent and/or had indwelling catheters.

All 97 isolates had similar susceptibility profiles: resistant to ciprofloxacin, gentamicin, ampicillin, amoxycillin/clavulanate, tricarcillin/clavulanate, aztreonam, and cefuroxime; decreased susceptibility to ceftazidime and cefepime; and susceptible to imipenem and meropenem. Double-disc tests indicated that all strains produced extended spectrum beta-lactamase(s). All the isolates belonged to 1 of 3 E. coli serotypes: 79 were 0153:H31, 13 were 0142:H10, and 5 were 0102:H6.

Giant Lesions in Multiple Sclerosis: A Diagnostic Challenge 

Bruria Shalmon, Dvora Nass, Zvi Ram, Anat Achiron

Institute of Pathology, Neurosurgery Dept. and Neuroimmunology Unit, Sheba Medical Center, Tel Hashomer

Multiple sclerosis is the most common demyelinating disease of the central nervous system affecting young adults, in which destruction of the axon myelin sheath disturbs signal transduction. The disease course is usually remitting and relapsing, but sometimes there is steady neurological deterioration.

The diagnosis depends mainly on an adequate clinical history and neurological examination. Evoked potentials, elevated cerebrospinal fluid gamma globulin with oligoclonal bands, and imaging studies, mainly magnetic resonance imaging (MRI), also contribute to the diagnosis.

Multiple sclerosis may occasionally present as a mass lesion that clinically and radiologically is indistinguishable from a brain tumor. We present 2 cases of giant tumefactive lesions, proven by brain biopsy to be of demyelinating nature.

Pre-induction sports participation of 392 elite infantry recruits was evaluated for correlation with incidence of stress fractures (SF) during 14 weeks of basic training. 23.7% developed lower extremity stress fractures. 72% of the recruits had participated in sports on a regular basis during the 2 years prior to induction. Their fitness as examined by the Bar-Or induction fitness test, was significantly better than that of those who had not trained. 14.9% of the soldiers who had previously participated in ball games (primarily basketball) as an only sport suffered stress fractures, compared to 31.0% of those whose only sport was running (p<0.005).

Training for only 6 months prior to induction had no effect on the incidence of SF. The reason for the difference between ball games and running is probably related to the higher strains and strain rates developed during ball games and to their multidirectional nature, as compared to running.

These findings suggest that participation in a pre-induction program that includes activities that create strains, such as basketball, can reduce incidence of SF in infantry recruits. The training period has to last at least 2 years.

There are 2 stages of alopecia, anagen and telogen effluvium, both of which may be associated with medication- related alopecia. We describe massive hair loss in a 51-year-old woman during treatment with Seroxat (paroxetine), which remitted after it was discontinued. Pathological mechanisms of drug-associated alopecia are complex and have yet to be fully elucidated.

Osteoarthritis results from progressive catabolic loss of cartilage proteoglycans due to imbalance between synthesis and degradation. The availability of glucosamine, an intermediate in mucopolysaccharide synthesis, can be rate-limiting for proteoglycan production in cartilage tissue culture.

57 patients suffering from osteoarthritis of the knee were randomized into a group treated for 4 weeks with daily IV glucosamine sulfate (GS) together with 800 mg chondroitin sulfate, and a placebo group. Knee pain at rest, on movement and on palpation, as well as range of knee motion were then recorded.

In the GS group, there was significant reduction of clinical symptoms (p<0.01), but no significant reduction in the placebo group. Physicians' assessment of tenderness and range of motion were significantly in favor of the GS group (p<0.01). In those treated with glycosamine there were no adverse reactions and no changes in laboratory blood tests.

Adult articular cartilage lacks the capacity for self-repair. The limiting factor appears to be the inability of chondrocytes to proliferate while embedded in the extracellular matrix typical of hyaline cartilage. Cartilage defects larger than 1 cm² change articular biomechanics and lead to eventual osteoarth-ritis and joint destruction.

During the past decade, several competing techniques have evolved to stimulate articular cartilage repair. Small lesions can be successfully treated by either micro-fracture or osteochondral cylinder grafting. The latter technique allows immediate weight bearing but leads to damage of previously uninvolved areas of articular cartilage, which limits its application to lesions of less than 2 cm².

When the damaged area is more extensive, grafting of autologous chondrocytes should be considered. First a diagnostic arthroscopy is performed to assess the damaged area and a small cartilage biopsy is taken. 6 weeks later, arthrotomy and chondrocyte transplantation are performed. In the interval, the antologous chondrocytes have expanded by 2 to 3 orders of magnitude. Our experience to date includes 10 cases with follow-up of 6 months to 5 years. Preoperative complaints of crepitation and locking disappear. There is functional improvement and pain reduction of approximately 50%. This procedure, currently limited to patients under 55 years of age with limited damage to an articular surface, for the first time allows reconstruction of damaged articular areas without resorting to allografts.

Acute epidural hematoma is very rare in the elderly after head injury. It is usually associated with extremely high mortality or severe disability. In an 87-year-old woman a large, hyperacute, epidural hematoma was diagnosed. She was treated promptly and enjoyed an uneventful, complete recovery. This exceptional case should encourage an intensive approach even in seemingly minor head trauma in the elderly.
