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.

Mastocytosis has a highly variable clinical expression, and systemic mastocytosis is occasionally associated with a myeloproliferative or a myelodysplastic disorder. These patients often present without skin involvement and have a very poor prognosis. We report a 72-year-old man with this condition who had spells of flushing and dyspnea, myelo-fibrosis, and high serum and urine histamine levels.

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.

Cryptococcal meningitis (CM) is common in the immunocompromised (especially due to AIDS), but also occurs in immunocompetent subjects. CM can complicate cryptococcal pneumonia (CP) not only in the immunocompromised but also in the immunocompetent. We describe a healthy 26-year-old man who developed a prolonged lung infection. Diagnosis of cryptococcal pneumonia was established from bronchoscopic washings. He recovered spontaneously, so no antifungal treatment was given.

4 months later he was admitted with cryptococcal meningitis and was treated successfully with amphotericin B. An extensive immunologic study revealed no abnormalities. Since CM can complicate cryptococcal pneumonia, it is recommended that patients with CP be followed, even if recovery is apparently complete.

Computerization in a Community Health Service Provider

Boaz Porter

Maccabi Health Services, Beer Sheba

As the second largest health service provider organization in Israel, we have been progressively computerized. The process was begun in 1988, focusing on improving administrative and financial processes.

Today there is a single centralized database for 6,000 users. The system monitors member eligibility, accounting procedures and clinical processes, including diagnoses, laboratory tests, imaging procedures and drug-prescribing. The potential of the computer for physician support is now being realized through integration of clinical guidelines and reminder systems into the computerized clinical record. In addition, the centralized database is used for quality improvement, facilitating cost-effective drug-prescribing and efficient use of technology.

The establishment of a computerized working environment for 2,000 physicians and 4,000 other healthcare workers serving 1.3 million patients is a unique model for the development of community health services. Data regarding demographics, disease patterns, drug-prescribing, use of new technology and costs are now readily available to all, from senior management to the individual physician in independent practice.

The computer revolution has also presented a new set of problems such patient-record confidentiality and the effect of the computer on the physician-patient encounter.

Between 1981-1993 581 women with primary breast cancer were treated by breast conservation. Their mean age was 56‏12 years and 63% were postmenopausal and 37% pre- or perimenopausal. The median follow-up time was 56 months. 45% had pathological Stage I disease, 49% Stage II, 2.5% Stage III and 3.5% clinical Stage I-II disease. 54% of lesions were excised with good margins, 10% with close margins (<0.5 cm), 9% with microscopic residual, 3% with macroscopic residual, and in 24% margins were not reported. Adjuvant therapy, consisting of combination chemotherapy and/or hormones, was given to 69%.

Radiotherapy, usually 50 Gy tangential photon irradiation to the whole breast, was given to 564 (97%); an electron or photon "boost" to the tumor with a median dose of 17.5 Gy was given to 378 (65%). Most of those with positive nodes received 50 Gy to the lymphatic drainage system.

1 year after radiotherapy cosmetic results were rated as "good" or "excellent" in 80%, "moderate" in 17% and "poor" in 3%. The 5-year actuarial survival was 97% in Stage I and 88% in Stage II. 37 patients (6.5%) developed breast recurrence; 11 of these (2%) had simultaneous distant metastases. 5 (<1%) developed axillary or supraclavicular lymph node metastases, and 81 (14%) developed distant metastases. Most local recurrences were in those younger than 40, and in those with primary tumors >1.75 cm.

The satisfactory level of local control achieved is attributed to the high doses of radiation (up to 75 Gy) administered to those with high risk lesions.

The usual treatment of complicated neonatal necrotizing enterocolitis (NEC) is resection of the necrotic bowel, lavage of the peritoneal cavity and diversion enterostomy. Low-birth-weight premature neonates with this condition are in special danger if general anesthesia and full exploratory surgery is contemplated.

A relatively simple alternate procedure is percutaneous insertion under local anesthesia of a soft abdominal drain, most often in the right lower quadrant. The procedure is done in the neonatal intensive care unit without moving the whole set-up to the operating room.

4 such cases have been treated within the past year. 3 were discharged home as they did not require additional surgical treatment, not having developed intestinal stenosis or obstruction. 1 recovered from the acute episode, but succumbed to a severe intraventricular hemorrhage and respiratory failure 7 days after the procedure.

Our limited but most gratifying experience, in addition to similar experience of others, encourages us to recommend this simple surgical approach in the very sick low-birth-weight premature with fulminant NEC.

During the August 1998 heat wave in Tel Aviv we admitted many patients for acute heat-related illness; 6 had severe heat stroke and were admitted in critical condition. We describe their clinical courses during the first 5 days of hospitalization, including response to treatment and implications for future management of this disorder.

The mean APACHE II score of the 6 was 30±3.5 and mean Glasgow Coma Scale rating 3.5±0.5; they were in hypovolemic shock and respiratory failure, necessitating mechanical ventilation. Despite early effective therapy (core temperature in all was reduced to less than 398C in less than 1 hour), there was 1 death (mortality 15%) and 4 required further intensive care for life-threatening multiple organ failure.

During severe heat waves a significant number of referrals for acute heat-related illness must be anticipated, possibly overwhelming admission capacity of regional intensive-care units. Severe heat stroke complicated by multi-organ failure is not necessarily related to prior physical activity. Although important in determining prognosis, early treatment does not prevent severe complications. Mechanisms regulating body heat may remain disturbed for days following early treatment and apparent stabilization, mandating continued hospitalization.

Superficial Skin Necrosis in Short Bowel Syndrome

Arie Eisenman, Rafael Enat

Dept. of Medicine B, Rambam Medical Center and Rappaport Faculty of Medicine, The Technion, Haifa

Short bowel syndrome causes a complex of symptoms due to compromise of small intestinal nutrient absorption. A 60-year-old woman underwent major resection of the small intestine due to a road accident 3 years ago. The sole manifestation of short-bowel-syndrome was superficial skin necrosis due to vitamin K deficiency. She was asymptomatic for a long time, until treatment with antibiotics further intensified initially subclinical malabsorption.

It is not clear why there had been no other symptoms and why the main impact was on the fibrinolytic system rather than the coagulation system, as is usually the case. It is recommended that patients after major resection of the small intestine be closely monitored for coagulation function if an oral antibiotic is prescribed.

Major pancreatic trauma challenges the trauma surgeon with diagnostic problems and choices of treatment modalities. The most important determinant guiding management is the integrity of the main pancreatic duct. The preoperative and intraoperative assessment and treatment of pancreatic injury may be difficult, especially when concurrent severe injuries are present. There are alternative approaches in the management of the traumatized pancreas when ductal injury is not obvious during initial exploratory laparotomy.

A-V Junctional Arrhythmia Due to Oral Phenytoin Intoxication

Phenytoin (Dilantin) is the drug of choice for most of the convulsive disorders. However, even when given orally it causes many adverse reactions, mainly affecting the nervous system, both central and peripheral. When administered intravenously, severe cardiovascular reactions may occur, including conduction disorders, sinus arrest, atrioventricular block or hypotension.

Medline screening did not reveal previous reports of arrhythmias induced by oral phenytoin. We present a case in which oral phenytoin administered chronically for a convulsive disorder caused atrioventricular junctional arrhythmia.

Road accidents, work accidents, or other trauma can cause impotence and are frequently followed by insurance claims. During 1990-97 we examined 230 males with such a complaint. All underwent full polysomnographic recordings in the sleep laboratory for 2 nights, during the course of which NPT (nocturnal penile tumescence) was examined with special equipment. It was assessed by an experienced technician following planned awakenings from REM sleep.

In 75 of the 230 subjects (33%), satisfactory erections were observed. In 100 (43%), who experienced at least 3 periods of REM sleep, no erections occurred. These patients were categorized as suffering from organic impotence. In the remaining 55 (24%), the results were inconclusive, with only partial erections or not enough REM sleep periods.

Since a man recognized as suffering from impotence may be awarded large monthly payments for life, these examinations, in our opinion, are an important tool to prevent unjustified claims, and can save the state unnecessary expenses.
