Cortical blindness has been occasionally reported as a complication after cerebral angiography, but is rare after coronary angiography. The contrast agent is believed to be responsible for the sudden development of blindness. Although the exact mechanism is unknown, it appears that the contrast agent disrupts the blood brain barrier, mostly in the occipital areas.

We report a 77-year-old man who suddenly developed transient, bilateral cortical blindness 4 hours after coronary angiography. Using contrast enhancement, the CT scan showed typical, symmetrical involvement of both occipital lobes. There were no other neurological deficits. Vision and CT findings returned to normal within 48 hours.

Glaucoma, the third leading cause of blindness in the western world, is characterized by painless, gradual loss of visual fields which may lead to severe visual impairment or even blindness. In 4 years of operation of a mobile glaucoma unit for screening and early diagnosis of glaucoma, 10,037 subjects aged 18-95 years were screened (4504 women, 45%); 55% were under 50 years (Graph 1).

Ocular hypertension was diagnosed in 8.0%; primary open angle glaucoma (POAG) in 0.8%, with 2/3 already under treatment, the rest newly diagnosed. Pseudo-exfoliative glaucoma was diagnosed in 0.2%; only 2 cases had closed angle glaucoma; 91% of those screened were normal (Fig. 4; age stratification, Graph 3).

POAG increased with age, from 0.2% in those under 40 years to 10% in those over 80; POAG was more common in men, but OHT was similar in both sexes (6.0% vs. 5.3%). There was no correlation between incidence of POAG and place of work except in the Sorek Nuclear Center (1.9% vs. 0.8%, p=0.11). Other conditions significantly more frequent in POAG than normals were diabetes mellitus (x 2.5), systemic hypertension (x 4), myopia (x 2) and history of intraocular surgery (x 6).

Anaphylaxis due to diclofenac sodium (Voltaren) is rare. We describe a 39-year-old woman who received a suppository of diclofenac for analgesia 6-hours after cesarean section. She developed severe angioedema and profound hemodynamic shock 10 minutes after the diclofenac, to which she had been exposed in the past without any side-effects. There are few reports of such an acute, life-threatening, multisystem reaction to this drug in the English literature.

Therapeutic injection of botulin toxin is well-recognized for reducing tonus in local dystonia. However, its efficacy in reducing spasticity in spinal cord injuries is still unproven. 4 men and 1 woman (mean age 39 years, range 20-56) with spinal cord injury and debilitating spasticity, and no response to standard treatment for spasticity received injections of botulin, 200-300 U, into 4-8 points in their legs to block muscle-nerve synapses.

In all 5 tonus was reduced in the area of the block, while in some it was also reduced in more distal muscles. In 1 there was reduced tonus in both the injected and contralateral leg. The therapeutic effect on tonus persisted for 3 months. In spite of objective improvement in tonus in all 5, only 3 felt subjective improvement, but in none was there improvement on standard functional scaling.

We found injection of botulin toxin effective in reducing tonus in the spinal cord-injured, and to some extent in improving subjective feeling of well-being in some of them. Obective measurement might show functional improvement after larger doses of toxin injected into more muscles. This might be necessary because the muscle mass of the legs is large and the intensity of involuntary contraction is especially high in these patients.

Endoscopic Sinus Surgery for Extracranial Complications of Sinusitis

E. Deutsch, I. Hevron

ENT Dept., Bikur Cholim Hospital, Jerusalem

Orbital subperiosteal abscess (SPA) and Pott's puffy tumor (PPT) are the major extracranial complications of acute sinusitis. These complications are aggravated by the close anatomic relationships between the nasal sinuses and the orbits and frontal bone. Furthermore, the rich diploic venous drainage of the region enhances the spread of the infection.

Between 1992 and 1997, 16 patients (mean age 12 years, range 2-15, 10 of them males), 11 of them with SPA and 4 with PPT were operated on by the senior author by means of endoscopic sinus surgery (ESS). Indications for operation included: CT findings of abscess formation and lack of clinical improvement after 48 hours of IV antibiotic therapy. Clinical resolution of symptoms was achieved in all and there were no operative or postoperative complications.

We emphasize and explain the advantages of ESS over external approaches in surgery for extracranial complications of acute sinusitis by several facts: the technique treats the source of the disease, clinical success rate is high, morbidity is low, and facial distortion and poor cosmetic results completely avoided.

Employment of Immigrant Russian Physicians

This study examined trends in the employment of immigrant physicians from the former Soviet Union. We studied the changes in the proportion of immigrants employed as physicians between 1994 and 1998, job characteristics, positions, professional status, and improvement in employment characteristics, professional status, and in wages due to increased seniority.

The study population consisted of 7,000 physicians who had immigrated to Israel by June 1992 and had applied to the Ministry of Health for medical licensing. Of these, 726 were interviewed in 1994 and in 1998 all 726 were again approached and 84% were interviewed by telephone.

Of those interviewed in 1998, 63% were working as physicians, 21% in another occupation, and 16% were not working at all. Of those with medical licenses, 79% were working as physicians. Of those interviewed in 1994, 93% were still employed as physicians in 1998, and 88% of them had been so employed continuously. As of 1998, 85% of those interviewed had 5 or more years seniority as physicians in Israel, and half had been working for more than 5 years at their current place of employment.

The best predictor-variable for employment as a physician in 1998 was employment as a physician in 1994. The proportions of those employed by a public employer, of those earning monthly salaries, and of those with a tenured position, were greater in 1998 than in 1994.

In 1998, 70% reported being employed in a authorized staff position. Funding for the salaries of 75% of these physicians came from the budget of their place of employment, not from a grant, stipend, or temporary fund for the assistance of immigrants. These proportions increased with seniority. The proportions of specialists (22%) and residents (37%) had increased in 1998 relative to 1994 (when they were 8% and 23% respectively). In addition, since 1994 gross hourly wages had increased with seniority in real terms by more than 100%.

These findings are evidence of work stability and improvement in employment conditions of these immigrant physicians. Further, the 1998 follow-up indicated a trend toward becoming "established" and improvement in professional status. However, it also revealed models of temporary employment, not in compliance with physicians' collective work agreements, a situation that warrants examination. It is also important to examine the implications of the absorption of so many physicians for medical manpower in Israel, and for overall expenditure on health.

It is clear to experts in the health care industry that with regard to medical decision-making, considering costs of medical devices is not a good index, but it is highly important to include medical aspects. This approach guarantees an advance and an appropriate method.

We present a cost-effectiveness analysis to target the optimal strategy of how to use medical diagnostic devices in cases of knee injuries. Today, one of the more common medical emergency referrals seen worldwide is in the area of orthopedics, knee injuries in particular. They can harm soft tissue, bone tissue, or both simultaneously. The diagnosis of soft tissue injury is difficult at best. Among the devices helping the clinician make an accurate diagnosis are MRI and ultrasound (US).

We conclude that US is superior to MRI in this condition. This is especially true when the orthopedic examination leads to the suggestion of arthroscopy. The results were not modified, and a sensitive study of the parameters that influence the decision- making process was undertaken. Decision-makers should not consider medical outcome alone, but should take into account the costs. A clinical study should validate the assumption on which this study was based.

Gyrate atrophy of the choroid and retina is a rare degenerative disease, characterized biochemically by a marked increase in blood ornithine levels, due to deficiency of ornithine S-amino transferase. 4 men aged 35, 36, 48 and 62 years are described with different stages of myopia, night blindness and loss of peripheral vision, which progressed to tunnel vision and partial blindness. Onset of the disease was at ages 3, 10 and 15 years, respectively, while in the 4th patient there was delayed expression starting at about age 50. Most had posterior subcapsular cataracts, and the ocular fundus exhibited demarcated circular areas of chorioretinal degeneration. So far the only patients described in Israel have been of Iraqui origin. Our fourth patient originated from Istanbul, and he may represent a hitherto undescribed variant with a much delayed expression of the disease.

Locoregional recurrence of rectal cancer ranges between 20%-50% following apparently radical surgery. Radiation has the potential of reducing this high rate of recurrence and residual disease. A retrospective analysis of 78 patients with locally advanced, biopsy proven, adenocarcinoma of the rectum treated between 1980-1987 was conducted. 28 (36%) were treated by surgery alone (surgery); 29 (37%) by surgery and postoperative radiotherapy (post-op); and 21 (27%) by surgery and preoperative radiotherapy (pre-op). 41 were females and 37 males. The median age was 62 years (range 25-90).

All tumors were resectable. 42 patients (54%) underwent abdomino-perineal resection and 36 (46%) anterior resection patients [8 Dukes B₁ (10%); 37 B₂ (47%); 2 C₁ (3%); 31 C₂ (40%]. Local recurrences were verified by transanal or ultrasound guided needle biopsy.

The 5-year actuarial survival rates by the Kaplan-Meier method for 75 evaluated patients was 55%. Overall 5-year actuarial survival was significantly higher (p=0.001) in pre-op radiotherapy (95%) compared to surgery alone (45%), or surgery with postoperative radiotherapy (32%). The data were significant (p=0.006) for patients with stage B tumors, but not stage C. This trend of improved survival held also at 8-year follow-up (80% pre-op; 32% post-op; 27% surgery). The 5-year actuarial local control was significantly better (p=0.03) for the pre-op irradiated patients (22%), compared with surgery only (56%) and post-op radiotherapy (38%). Local control was better (p=0.02) for Dukes B tumors in the preoperative group, but not Dukes C tumors.

Actuarial 5-year survival of those without distant metastases was 87% for pre-op patients, 62% for surgery alone and 48% for post-op radiotherapy. As all patients were clinically classified as advanced rectal tumors, tumor downstaging by preoperative radiotherapy seems to be paramount for local control. Improved local control translates into a siginificant advantage in overall actuarial survival.

Scrofula (mycobacterial cervical lymphadenitis) has been well-known for thousands of years. Atypical mycobacteria were first categorized by Timpe and Runyon in 1954. Treatment has varied over the centuries, from exclusion therapy in ancient Greece, through digitalis, iodide, chemotherapy, and surgical excision. The varied differential diagnosis and consequent diagnostic and therapeutic challenges make reassessment of this almost forgotten disease necessary.

21 patients with typical mycobacterial cervical lymphaden„itis seen in over the past 5 years were reviewed. Age distribution ranged from 1-14 years, with peak incidence at 4 years; 9 were boys and 12 girls. Most presented with nontender, palpable neck masses and minimal constitutional complaints. Adenopathy was unilateral in all cases but 2. Mycobacterium avium-intracellulare and M. fortuitum were the main causative organisms. All underwent excision of the affected nodes. Long-term follow-up has been uneventful, except for 1 case of local recurrence requiring re-excision.

This study emphasizes the marked variability in the clinical presentation of scrofula in children, stressing the importance of the differential diagnosis between tuberculous and atypical mycobacterial cervical lymphadenitis. The treatment of choice for the latter is complete excision of the affected nodes. Other treatment is followed by recurrence and unnecessary complications and should be avoided.

Nutrition for Women's Health

Dorit Nitzan Kaluski, Alex Levental

Dept. of Nutrition, Public Health Services, Ministry of Health, Jerusalem

Biological, environmental and social factors predispose women to cardiovascular diseases, malignancy, osteoporosis, diabetes, obesity and eating disorders. Their prevention requires that health services recognize women as a risk group and provide appropriate financial and professional resources. To develop and apply intervention programs for women, funding must be allocated for data collection, development and assessment of intervention programs and involving women in decision processes. We address the diseases and conditions in which nutrition may contribute to primary or secondary prevention of the specified diseases.

The Israeli health system has been undergoing major changes in recent years. Considerations of cost containment have led sick funds to open new out-of-hours services in the community to reduce visits to hospital emergency departments.

Referred and self-referred visits to our emergency department during a 1-month period were studied. Patients after trauma or whose visits resulted in hospitalization were excluded. Of the 505 encounters 56.3% were of women; the average age was 52.5±19.3 years (range 18-96). 57.4% visits were during working hours of primary care clinics ("working hours"), while the others were "out-of-hours" visits. Only 52.7% had a referral letter, 75% of them from the family physician. The quality of the handwriting in 46% was good, in 44% fair and the remaining 10% were illegible. A specific clinical question was asked in only 16% of the letters. A third of "working-hours" visits were self- referrals, rising to 64% in "out-of-hours" visits (p<0.001).

The most common diagnoses in discharge letters were: chest or abdominal pain, asthma, back pain, headache, nephrolithiasis and upper respiratory tract infection. The rate of self-referrals was relatively high throughout the day. Cost-containment efforts did not seem to eliminate self-referrals with "primary care" problems. The quality of referral letters should be improved both with regard to format and content.

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%.

Cervical pregnancy is a rare but serious complication. The most frequent presenting symptom is vaginal bleeding, and is thus common in inevitable abortion. Examination reveals a dilated cervix containing products of conception derived from the emptied uterine cavity. The pathologic criteria are cervical glands opposite the placental site, attachment to and actual invasion of the cervix by the placenta, a portion of the placenta below the posterior reflection, and no fetal parts in the corpus uteri. Treatment ranges from hysterectomy to treatment with chemical agents, mostly methotrexate. We present a case of ectopic, cervical pregnancy with exaggerated placental site in the cervix.

Many drugs used in children are based on pharmacological data obtained in adults. Therefore, many drugs are either unlicensed for use in children or are prescribed outside the terms of the product license (off-label). This pilot study assessed use of unlicensed or off-label drugs in hospitalized children.

Drug orders of patients admitted to a general pediatric ward were reviewed retrospectively in a random sample. Assessment was based on the data of the Physicians' Desk Reference and the Israel Drug Compendium. 80 different drugs and 278 drug orders were written for 92 patients (0.5 months - 11 years old, mean 26.9 months) in 97 admissions. Of these 52.9% were either off-label or unlicensed. Patients received 1 or more unlicensed or off-label drugs in 64.9% of admissions. They were more often off-label than unlicensed. The main reasons for use of off-label drugs were unusual doses and inappropriate age. The main reason for unlicensed drugs was modification of a particular formulation of a licensed drug.

This pilot study indicates that use of drugs in an off-label or unlicensed manner in children is probably quite frequent in Israel. Our data emphasize the need for licensing a large number of drugs for use in children, based on the same scientific principles as in adults. Further collaborative studies in different pediatric centers in Israel, involving different types of pediatric settings (ambulatory and in-hospital), is required to evaluate comprehensively the magnitude of this preliminary finding.
