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.

Atrophic gastritis is an autoimmune gastropathy in which there is destruction of gastric parietal cells. This results in intrinsic factor deficiency and disturbance in vitamin B12 absorption. Its clinical manifestationa are therefore the consequences of B12 deficiency and include anemia and neurological defect. In addition, lack of B12 results in metabolic changes, including disturbances of methionine metabolism and accumulation of homocysteine.

In recent years, there has been increasing evidence suggesting that hyperhomocysteinemia is a risk factor for thrombo-embolic disease. We describe a 51-year-old man with atrophic gastritis, severe B12 deficiency and hyperhomocystein-emia. The initial clinical manifestation was pulmonary embolism, without either anemia or neurological signs. B12 deficiency should therefore be considered in patients being investigated for hypercoagulability.

Acrylate glues used in a childrens' day care unit to close small surgical wounds were compared. In 157 children, aged 12 weeks to 3.7 years, either Histoacryl or Dermabond was used (respectively, H: Ethicon Inc., Johnson & Johnson, NJ or D: Dermabond, Braun Surgical Gmbh, Melsungen, Germany). Operations were for inguinal hernia (110 cases), hydrocele (25), undescended testis (16), umbilical hernia (13) and funiculocele (3).

1 week after surgery the wounds were evaluated in terms of integrity of closure, redness or infection, need for antibiotics, wound granuloma, and parental satisfaction with instructions and actual method of wound caring. 3 months after surgery the wound/scar was reexamined.

The margins of the wounds were separated partially or completely in 8 of 85 in group H (9.4%) while in the D group, 2 wounds (2.4%) had partially opened (p<0.05). There were no differences between the glues with regard to wound infection or cosmetic results. Parental satisfaction was higher with D (96%) than H (82%) but the difference was not statistically significant.

It is convenient to use glue to close operative wounds in children after ambulatory surgery. The use of D significantly reduced wound ruptures compared to H. Long-term cosmetic results were similar.

Oral rehydration (OR) for acute gastroenteritis in infants and children has been shown to be as effective as IV therapy, with less discomfort and lower costs. In this retrospective study we compared 2 pediatric wards, in 1 of which only a standardized, simplified, bedside protocol, based on American Academy of Pediatrics guidelines, was used.

There were no significant clinical characteristics in the 208 patients. In the ward which used the above protocol, OR utilization was significantly more frequent than in the other ward (48% versus 15%), thus saving equipment costs of nearly $1,000/3 months. There were no significant differences in outcome between the wards.

We conclude that introducing a standardized management protocol may increase OR utilization in hospitalized children with acute diarrhea.

We report a 75-year-old man with myasthenia gravis for many years, who was hospitalized because of cough, fever, and dyspnea. Chest x-ray revealed a bilateral pleural effusion. Adenocarcinomatous cells were found in the pleural fluid. Computerized tomography of the chest showed widespread pulmonary dissemination of the tumor.

The relationship between myasthenia gravis, an autoimmune disease involving the motor end-plate, and malignancy (thymoma) has been widely recognized. Current literature documents few reports of lung malignancies with concurrent development of myasthenia gravis. A tentative explanation, based on current research, is provided for the possible role of myasthenia gravis and the late development of lung cancer. Moreover, a model for the autoimmune phenomenon and the development of late malignancies will be provided with explicit explanations. It is important to search for occult, developing malignancies in newly diagnosed autoimmune diseases.

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

Ben Zion Silverstone

Eye Dept., Shaare Zedek Medical Center, Jerusalem

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.

Dept. of Surgery A, Meir Hospital, Kfar Saba; and Sackler School of Medicine, Tel Aviv University

The first 1,000 laparoscopic cholecystectomies performed in our department were reviewed. There was no operative mortality; conversion to open cholecystectomy was necessary in 2%. In the last 600 cases the rate of conversion had decreased to 0.5%. There was common bile duct injury in 0.3%, with the injuries identified during primary surgery. This clinical experience is consistent with previous studies, which proved that laparoscopic cholecystectomy is safe and should replace open operation as the procedure of choice.

Transport of pediatric trauma victims, within as well as between medical centers, has become a frequent event and an integral activity of pediatric critical care units. Monitoring patients during transport is of utmost importance, as an unstable environment poses an increased threat to the patient's stability. The level of monitoring and care should approximate that of the critical care unit. Monitoring end-tidal CO² (EtCO²) has become routine for many pediatric intensive care unit patients but technical problems have limited its use during transport.

Our transport team uses a transportable EtCO² monitor of the side-stream type (NPB 75), requiring very small samples; midstream sampling overcomes humidity interference. The monitor is small and lightweight, operates on a rechargeable battery and is especially designed for the demanding environment of transport.

From October 1997 through January 1999, 187 pediatric patients, 62 of whom were trauma victims, were transported for a total of 45 hours, including 2 hours of in-flight transport. Age range was 3 months to 16 years. Of the 53 monitored for EtCO², in 9 (17%) monitoring resulted in a significant, immediate change of treatment during transport.

We find EtCO² an important adjunct in monitoring pediatric trauma patients during transport. In addition to conventional monitoring of heart rate, blood pressure, respiratory rate, body temperature and blood oxygen saturation, we suggest EtCO² as the sixth vital sign that should be monitored.

The medical records of all patients referred to the emergency department (ED) of Sheba Medical Center for renal colic during 1996 were analyzed. Patients discharged from the ED and those hospitalized were compared.

There was no significant difference between the 2 groups with regard to average age or sex distribution. Statistically significant differences were found with regard to frequency of chills and fever, history of renal colic, referral for renal colic during that year or hospitalization for renal colic or nephrolithiasis, previous positive imaging, stone removal by surgery or extracorporeal shock wave lithotripsy, fever exceeding 37.5^o and administration of fluids, pethidine or pramin in the ED, prolonged stay in the ED and previous appendectomy.

A conditional regression model tested the predictive value of each of those factors. Inclusion of independent variables into the model led to an overall correct classification rate of 84.43%, with 44.83% sensitivity and 93.16% specificity. There were correlations between referrals for renal colic, overall renal colic rate and average monthly temperature, so there was no pure correlation between average monthly temperature and referrals to the ED for renal colic.

The major indications for hospitalization were actually the clinical ones, indicating either an active metabolic disease or suspected obstruction of the urinary tract. Treatment in the ED and duration of the visit indicated disease severity.

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.

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.

Specialty Clinics - Gain or Loss?

Epidemiology Dept.; and Pulmonary Unit of Soroka Medical Center; Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer Sheba

We evaluated the significance of first visits to our pulmonary clinic with regard to diagnosis and treatment by reviewing records of 287 new referrals by medical care providers (Sept. 1998 - Feb. 1999). At the first visit the diagnosis was changed in 30%, and treatment in 40%. These are minimal figures because evaluation had not been completed nor the diagnosis determined in all cases, while further investigation and follow-up continued.

In light of these findings, we believe that recent pressure on primary care physicians to avoid referrals to specialty clinics would result in short-term savings, but in the long term, would increase expenses and diminish quality of care. It is important to consider ways to maximize the interaction between the primary care physician and the specialist to maintain quality of care and decreases costs.

Opinions of the National Health Insurance (NHI) Law held by primary care physicians were surveyed. A questionnaire was submitted (April-July 1997) to 930 primary care physicians employed by sick funds, including general practitioners, family physicians, pediatricians and internists. Response rate was 86%.

They supported the main components of the NHI law. It was considered desirable "to a great" or "very great extent" to allocate funds to sick funds based on age and number of members (76%), to require them to accept all applicants (72%), to designate a uniform basket of services (65%), to allow members to transfer freely between funds (63%), and to allow sick funds to sell supplemental insurance (59%). However, only 41% were satisfied with the implementation of the law.

Multivariate analysis showed that employment by Maccabi, Meuhedet, or Leumit sick funds had an independent effect on low satisfaction with the law as implemented, and on negative opinions about the uniform basket of services, the accepting of all applicants, and allocation of funding based on age and number of members. Those employed by the Maccabi and Meuhedet funds were in favor of allowing sick funds to sell supplemental insurance.

The findings of the study have implications for policy-makers interested in increasing support for national health reform by physicians. It is important to examine possibilities of developing direct channels of communication between national policy-makers and physicians, as well as institutionalizing mechanisms that involve physicians directly in formulation of national policy.
