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.

There are more than 200 procedures for repairing stress urinary incontinence. We evaluated the safety and efficiency of the Burch laparoscopic procedure in 32 women with urodynamically proven genuine stress incontinence.

Mean operating time was 40 minutes and mean hospitalization time after the procedure was 30 hours. The cure rate was 97%, similar to that rin other studies (80-95%). The major complications w2 cases (6.2%) of unintended bladder injury, diagnosed and repaired laparoscopically. Although follow-up has only been for 3-42 months, the high cure rate and safety and advantages of laparoscopy over laparotomy, make laparoscopic Burch colposuspension the procedure of choice for repairing stress incontinence.

Coloring the Floor of Schlemm's Canal in Deep Sclerectomy

Increased intraocular pressure in glaucoma, resistant to maximal tolerated medical therapy, can be relieved by deep sclerectomy. Its advantage over classical trabeculotomy is fewer postoperative complications. This probably results from its being relatively noninvasive, since the anterior chamber is not penetrated.

Successful deep sclerectomy requires preservation of the trabeculo-descemetic membrane, which forms part of the floor of Schlemm's canal. Aqueous flows from the anterior chamber across the trabeculo-descemetic membrane and into the ocular venous drainage. Despite the importances of its preservation, during deep sclerectomy it is perforated in 10-15% of cases.

Coloring the endothelium lining the floor of the canal with gentian violet solution improves visualization of the membrane and thus aids in its preservation. Its use makes the procedure easier and should improve results.

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.

Liver transplantation is the treatment of choice for end- stage liver disease. During the past 8 years we performed 102 liver transplants in 84 adults and 16 children. In the adults, 9 were combined transplants: 1 a liver-pancreas transplant for type I diabetes, and 8 liver-kidney transplants. In the children, transplants included 5 whole-livers, 5 left-lateral liver segments from living-related donors, 4 reduced-grafts of right or left lobes, and 2 split left-lateral segments.

At a mean follow-up of 31 months (range 1-96) 70 were alive, 3 had died during surgery and 15 during the first postoperative months. Mortality was due to primary graft non-function (7), sepsis (10), intracranial hemorrhage (1), tumors (4), recurrent hepatitis B (2), biliary strictures (2) and chronic rejection (1). The 1- and 4-year survival rates were 79.5% and 69.6%, respectively.

After transplantation, 10 developed biliary stricture (5 corrected by balloon dilatation) and 8 anastomotic stricture (7 corrected by surgery), and there were 2 multiple intra-hepatic strictures. There was hepatic artery thrombosis in 5, including 4 children. In 3, grafts were salvaged by thrombectomy and 2 others underwent re-transplantation. In those who survived transplantation by more than 1-month, recurrent hepatitis B was seen in 6 of 17 (35%) and recurrent hepatitis C in 12 of 19 (63%).

Thus, results of our first 100 liver transplants are similar to those reported by larger centers, showing that in an appropriate setting good results can be achieved by small transplant programs.

Cholangiocarcinoma accounts for about 1% of all malignant tumors. They are difficult to diagnose because of their small size and their location. Although surgical resection is the best therapeutic approach, most patients undergo unnecessary exploratory laparotomy due to incorrect preoperative diagnosis.

We present our experience with laparoscopic ultrasound (LU) in the evaluation of cholangiocarcinoma and determination of tumor spread and vascular involvement. Of 25 patients referred for surgery, 6 were excluded following LU and were referred instead for palliative treatment. Diagnosis of the tumor was successful in 92%, and vascular involvement was diagnosed in 46%. LU should be an integral diagnostic test in the evaluation of choriocarcinoma.

Results of a 1996 survey of hospital pharmaceutical services in Israel are presented. A questionnaire was mailed to 46 pharmacy directors in Israel hospitals of which a total of 33 were returned (72%).

The main services provided at hospital pharmacies are production of pharmaceuticals and inventory management. The pharmacy directors estimated that more then half of their pharmacists' time was spent on technical work that did not need their academic, professional knowledge. In Israel general hospitals there are on the average 1.23 full time pharmacist positions per 100 hospital beds and 1.09 positions for other pharmacy employees.

A similar survey carried out in the United States showed an average of 7.4 pharmacists per 100 hospital beds. Pharmacists there have broad clinical roles which, in general Israeli pharmacists do not have.

Computer systems are used in our pharmacies mainly for inventory management. About half of the directors did not think that the location, structure and furnishings of their pharmacy were appropriate for its role.

Under current conditions, Israel hospital pharmacies are not organized to provide pharmaceutical services beyond inventory management and pharmaceutical production. Appropriate budgets and personnel are required to develop clinical pharmacy services at Israel hospitals. This would lead to improved quality of drug treatment and cost-containment and would allow pharmacists to exploit their knowledge, skills and training that under the current system, are only partially utilized.

Hereditary hemorrhagic telangiectasia (Osler-Weber-Ren-du syndrome) is a group of autosomal dominant diseases with variable penetration, characterized by vascular malformations. Recently hereditary hemorrhagic telangiectasia has been found to be a phenotypic expression of mutations in genes located on chromosomes 9 and 12, and possibly of other genes located on other chromosomes.

We describe 2 patients with hereditary hemorrhagic telangiectasia and pulmonary involvement who presented with repeated complaints of dyspnea and cyanosis and were diagnosed as having long-standing asthma. Both were treated with therapeutic catheterization and embolization with good clinical outcomes.

Type 2 diabetes has been considered rare in children and adolescents. Recently, increase in the incidence of type 2 diabetes has been reported among adolescents in various parts of the world. We report the occurrence of type 2 diabetes among adolescents in Israel.

A boy of 14 and girls of 16.5 and 17 were pubertal and extremely obese, with a body mass index (BMI) between 39-47 kg/m². Acanthosis nigricans, elevated diastolic blood pressure, and hirsutism with menstrual disorders, were associated with insulin resistance, and should raise suspicion of type 2 diabetes. Significant obesity and strong family histories of type 2 diabetes appeared to be important risk factors. Since type 2 leads to long-term morbidity and mortality, its early identification and appropriate treatment are crucial.

The Internet is efficient in coping with the ever-increasing volume of medical knowledge. This and other functions have lead to its integration into daily medical practice. It is therefore imperative to disseminate its use among physicians, as some, unfamiliar with the personal computer (PC), may be reluctant to learn to use it. We therefore developed a course for training physicians in the basics of Internet use, consisting of 6 sessions of 2 hours each. It includes training in PC operation as well as in the main Internet functions. The topics are medicine-oriented, including Medline search, general info search, exploring medical sites and reading medical journals on-line.

41 physicians (8 groups of 4-6 each) with various specialties attended, of whom 38 completed a feedback questionnaire 4 weeks later. 79% reported using the Internet either at home or at their working place. The function used mostly was Medline Search (68%). Although 83% had not been familiar with the PC before, 96% stated that the course was clear and understandable and 99% expressed satisfaction with the quality of the teaching. Based on these results we recommend this course as a model for teaching physicians the use of the Internet.

Pancreatic lesions present a diagnostic challenge. Even modern imaging techniques are not sensitive enough in determining resectability of pancreatic tumors. A substantial proportion of patients therefore undergo unnecessary surgical exploration. We determined the impact of laparoscopy and laparoscopic ultrasound (LAPUS) examinations on surgical decision-making in 60 patients with pancreatic lesions.

Of 48 with solid pancreatic lesions, 22 were defined by LAPUS as having nonresectable tumors, while conventional imaging studies defined only 9 of them as such. 3 of these 9 underwent successful resections of the pancreatic mass. Surgical intervention was ruled out by LAPUS in 16 patients (33.3%) but 26 had resectable lesions of whom 25 underwent surgery. 3 of this group were found to have nonresectable tumors at surgery, a false-positive rate of 6.2%. Overall sensitivity of LAPUS in our series was 88%.

In 12 patients with cystic pancreatic lesions LAPUS contributed significantly to the preoperative decision due to clear imaging of the cystic lesion. Additional information was obtained from ultrasound guided-biopsy of the cyst wall, as well as determination of tumor-marker levels in the cystic fluid aspirate. LAPUS contributed significantly to operative management in 58%.

Retinal damage caused by direct exposure to the sun's rays is well recognized by the ophthalmic community. Although functional ability in solar retinopathy is usually regained within weeks, some suffer long-term visual impairment. Anatomic damage to the retina, even in those who regain full vision, is permanent. We describe 2 cases of solar retinopathy, 1 of which remained with permanent loss of vision. The role of medical education in preventing damage from solar retinal hazards is stressed.

Resistance to antibiotics is considered the main reason for failure to eradicate Helicobacter pylori (HP). Resistance rates are different in developed and developing countries and are not known for Israel. We studied HP resistance rates in 40 patients who underwent esophagoduodenoscopy for various indications and were found to have gastric HP colonies.

Sensitivity was determined by E-test, using clarythromycin, amoxycillin, clindamycin, erythromycin and metronidazole. The resistance rate for metronidazole was up to 67% but that for clindamycin was only 10%. HP was very sensitive to both macrolide antibiotics, erythromycin and clarythromycin.

Lymphangioma is a benign developmental anomaly of the lymphatic system located in about 40% of cases in the neck and usually completely resectable. In some cases it invades adjacent structures such as the larynx, pharynx, or tongue. In such cases it is almost impossible to resect completely, as this would endanger vital structures.

We describe a baby born with a huge cervical lymphangioma which invaded the tongue, larynx, pharynx and other cervical structures. He was treated with bleomycin and aethoxysklerol. The sclerotherapy shrank the lymphangioma considerably and it became resectable. At 2 years of age the cosmetic result is good and vital function, such as swallowing and facial expression, are preserved.

It has been shown that the inspiratory muscles of patients with congestive heart failure (CHF) are weaker than normal. This weakness may contribute to dyspnea and limit exercise capacity. But respiratory muscles can be trained for increase in both strength and endurance. This study was designed to evaluate the effect of specific inspiratory muscle training (SIMT) on muscular performance, lung function, dyspnea and exercise capacity in moderate heart failure.

10 patients with CHF (NYHA functional class II-III) received 1/2 hour of SIMT daily, 6 times/week, for 3 months. They started breathing at a resistance 15% of their Pimax for 1 week and the resistance was then increased incrementally to 60%. Spirometry, inspiratory muscle strength and endurance, and the 12-minute walk test were performed before and after the training period. All showed an increase in inspiratory muscle strength and endurance. This was associated with a small but significant increase in FVC, a significant increase in the distance walked (458±29 to 562±32 m, p<0.01), and improvement in the dyspnea index score.

SIMT resulted in increased inspiratory muscle strength and endurance. This increase was associated with decreased dyspnea and an increase in submaximal exercise capacity. SIMT may prove to be useful complementary therapy in CHF.
