The incidence of ectopic endometriosis is 4% to 18%. The intestinal type is quite common with the rectosigmoid the most likely part of the bowel to be involved due to its pelvic location. A 43-year-old woman, whose symptoms, X-ray and endoscopic findings suggested malignancy of the rectosigmoid, is presented. Primary malignancy of the bowel was excluded by endoscopic biopsies. Histological examination at operation showed stromal sarcoma of the uterus with foci of endometriosis. There is no report in the English literature of transformation of intestinal endometriosis into malignancy, such as stromal sarcoma of the uterus, which imitates a primary malignancy with obstruction of the rectosigmoid.

In a previous nationwide study, we examined the rate of consanguineous matings in the Israeli Arab community. The average inbreeding coefficient was 0.0192, much higher than that reported for the general population of Israel, 0.0038 in 1956-7. The inbreeding coefficients of 69 Arab villages, towns and cities (excluding the Bedouin in the South) were determined. Knowledge of the inbreeding coefficients of the various local populations is of value for geneticists, pediatricians and gynecologists and for planning suitable health programs.

The use of different types of total hip implants in medical centers in Israel was surveyed. Questionnaires were sent to all orthopedic ward directors in Israel requesting information on the number of total hip arthroplasties performed between the years 1984-1993, the types of implants used, and whether attending physicians or residents perform the operations. 22 of 24 orthopedic wards responded but 1 ward was excluded because only the results for 1993 were reported. 5 wards reported more and 16 fewer than 50 operations a year. 15 different types of implants were in use in Israel in that period, and in 5 wards 5 or more types of implants were used. Only 1 of the wards performed more than 50 operations a year. We conclude that the indiscriminate use of multiple technologies in wards performing few operations can lead to the long "learning curves" previously associated with poor results. Orthopedic surgeons should resist the impulse to introduce new implants, thus improving results and lowering expenditure. The need for regulating the introduction of new implants is emphasized.

The common structural and functional brain imaging techniques are described from a practical, clinical point of view. The clinical indications for brain imaging in psychiatry are reviewed in relation to the specific limitations and advantages of each technique. The clinical applications of computerized tomography (CT), magnetic resonance imaging (MRI) and single photon emission computerized tomography (SPECT) are discussed in relation to the differential diagnosis between organic and functional psychiatric disorders. In a 55-year-old man with late onset of behavioral changes but without neurological signs the application of structural brain imaging (CT and MRI) in case management was demonstrated. The imaging findings involved the differential diagnosis between depression and focal brain lesions. In a 38-year-old man with personality changes and depression following a traumatic brain injury, time interval repeated functional brain imaging (SPECT) was used. Brain imaging reflected improvement in clinical status following treatment and was able to differentiate between reversible and permanent traumatic brain injuries. The superior yield of time interval repeated functional imaging in diagnosis and management of postconcussion syndrome is discussed.

Pediatrics Dept., Central Hospital of the Emek, Afula

In this era of antimicrobial medication, intracranial complications following otitis media are rare. We present a 5-year-old boy who suffered from petrositis (Gradenigo syndrome) and cavernous sinus thrombosis as combined complications of acute otitis media caused by fusobacteria. The diagnosis was made using imaging methods suited to the various structures of the skull. Cure was achieved by prolonged conservative treatment with antibiotics, with gallium scan for evaluation of the bone inflammation.

Q fever is caused by the rickettsia Coxiella burnetti, an obligate intracellular bacterium acquired by inhalation of infected dust from subclinically infected animals. Q fever may be acute or chronic; the chronic form mostly presents as endocarditis. Immunocompromised states and underlying heart disease are the most important risk factors. Usually the symptoms of Q fever endocarditis are nonspecific and diagnosis is often established very late. New criteria for diagnosis include a single blood culture positive for Coxiella burnetti, positive Q fever serology and characteristic echocardiographic studies. We describe a 49-year-old man with bicuspid aortic valve admitted with fever, weight loss and a new heart murmur. The diagnosis of Q fever endocarditis was established by positive Q fever serology, and an echocardiogram showing vegetations and valvular dysfunction. This case suggests that Q fever endocarditis should be considered in patients with "sterile" endocarditis.

During 1989-1994, there were 322 episodes of Gram-negative enteric bacteremia in 308 children. The incidence increased from 31/100,000 in children younger than 15 years of age during 1989-1991, to 50/100,000 during 1992-1994. The most common pathogens were Klebsiella, E. Coli, Salmonella and Enterobacter. 39% of episodes were nosocomial and a significant increase was recorded for each species during the last 3 years of the study. Klebsiella represented the most common pathogen causing nosocomial bacteremia, while E. coli and Salmonella were the main pathogens causing community-acquired bacteremia. In this study in southern Israel, the incidence of Gram-negative enteric bacteremia was significantly higher in Bedouin children, with the exception of bacteremia due to Salmonella, which occurred mainly in Jewish children.

To determine the prevalence of occupation-related eye injuries, we analyzed the records of 24,632 patients treated at our emergency surgical department over a 3-year period. Occupational accidents accounted for 17.6% of such cases. A third of them (1374 patients) were referred to the ophthalmic emergency room for further examination. In 89% (1223) of these, at least 1 pathological ocular finding was detected, and 8.3% (114) of them were hospitalized. Penetrating eye injuries were found in 5.2%(72). The commonest eye injury was corneal foreign body found in 42.8%.

Advances in Ophthalmological Photodynamic Therapy

Yoram Solberg, Michael Belkin

Goldschleger Eye Research Institute, Tel Aviv University and Chaim Sheba Medical Center, Tel Hashomer

Photodynamic therapy is a new experimental therapeutic technique which is attracting increasing attention. Its biopharmacological basis of action is the specific interaction of a photosensitizing compound with the cellular elements of pathological lesions. The photosensitizer is thought to enter specifically into the pathologic cells, where it accumulates. The lesion is then irradiated with a sensitizing laser-beam of specific wave-length to activate the photosensitizer, which then becomes a generator of free oxygen radicals. These radicals destroy the sensitizer-harboring pathological cells. The advantage of specifically destroying pathological lesions without affecting surrounding normal tissue is obvious. Recently, many experimental studies have been conducted to test the usefulness of photodynamic therapy for ocular disorders, mainly advanced age-related macular degeneration and uveal melanoma. Results so far are encouraging.

There are about 6500 births yearly in the Ashkelon District. 6% of the mothers are Ethiopians, most of whom immigrated to Israel since the early 90's. Our data are from 3 sources: birth certificates, infant death certificates, and the national population register. Birth rates in single mothers and rates of low-birth-weight births have declined over the years. Infant mortality and still-birth rates have also shown remarkable and consistent declines between 1990-1995. We conclude that improvement in life conditions of Ethiopian immigrants and better use of health services have had a great impact on birth outcomes and pregnancy patterns. The gap between Ethiopian immigrants and other Jewish communities in Israel is closing fast.

Acute infectious diseases of the gastrointestinal tract and food poisoning are problems of great importance in the Israel Defense Force (IDF). They involve individual and epidemic morbidity, with impairment of health of individual soldiers and in the activities of units. Outbreaks of gastrointestinal infectious diseases must be reported to the IDF army health branch, which conducts epidemiological investigation. This study is based on data from yearly epidemiological reports for 1978-1989, and from a computerized database for the years 1990-1995. The incidence of outbreaks is characterized by an unstable trend, It was highest at the end of the 80's (68.3 per 100,000 soldiers on active duty) and lowest for the last 2 years (1994-1995, 36.3 per 100,000). The incidence of soldiers involved in food-borne outbreaks has been more stable, constantly declining during the course of the years. There was marked seasonality with a peak in the summer months. Sporadic morbidity was constant in 1990-1995, with a yearly attack rate of 60% in soldiers on active duty. Shigella strains were the leading cause of outbreaks until 1993, while in 1994-1995 their proportion decreased, with an increase in the proportion of Salmonella strains. As to Staphylococcus aureus, its role in causing food poisoning has been characterized by marked changes. Shigella sonnei replaced Shigella flexneri as the leading strain. 73.3% of outbreaks were small, with fewer than 40 soldiers involved, while 5.4% of outbreaks affected more than 100 soldiers. Outbreaks in which a bacterial agent was identified or which occurred in new-recruit bases were larger than those in which a bacterial agent was not identified, or which occurred in active field unit bases. In conclusion, the rates of infectious disease of the gastrointestinal tract are still high, although there has been a marked decrease since 1994. The incidence of outbreaks has also decreased, as well as the role of Shigella as a leading causative agent.

To study the effect of stroke on the quality of life in younger adults, 199 patients 17-49 years of age who had sustained a first stroke between 1.11.92 and 31.10.93 were followed up. They were interviewed by telephone at 3, 6, 12 and 24 months after the event. 2 died during the first year of follow-up, and 8 had recurrent strokes. After 2 years, 8 additional patients had died and 4 had sustained recurrent events. Gradual improvement was reported within all age groups and in all areas. During the 3-6 months period, a mean of 4% improvement occurred in functional capability, 15% in social and recreational activity and 8% in return-to-work. The 6-12 month period showed an increase of 3% in improvement in mean functional capability, 10% in social and recreational activity and 2% in return-to-work. 1 year after the stroke 27% remained with moderate to severe disability, but over 86% were functionally independent in their daily living activities. There were no significant changes during the second year of follow-up in these statistics. 67% of those employed prior to their stroke returned to work and approximately 70% reported a return to prestroke social and recreational activity. These results demonstrate that the relatively high recovery rate and functional improvement during a year of follow-up were not accompanied by similar rates of improvement in emplyment and in social integration. They indicate the need for increased emphasis on long-term psychosocial rehabilitation services within the community.

Dept. of Prevention, Israel Society for the Prevention of Alcoholism

A study was conducted in the winter of 1996 among 2,220 Arab adolescents in northern Israel. This fourth study among Arab youth dealt with frequency of drinking and amounts of alcohol drunk during a drinking bout. Among Christian, Druze and Moslem males there were 81.72%, 49.61% and 31.93%, respectively, who drank. The figures for females were 36.75%, 11.25% and 12.78%. About 4% of Moslem males drank 5 drinks or more consecutively, daily or every 2-3 days. The need for preventive efforts in the Arab sector is stressed.

Suprascapular Nerve Entrapment in a Basketball Player

Atzmon Tsur, Radi Shahin

Rehabilitation Unit and Dept. of Neurology, Western Galilee Hospital, Nahariya

A basketball player was shown to have a suprascapular nerve lesion without any history of shoulder girdle trauma. This acute neuropathy, never previously described in basketball players, is a result of repeated micro-trauma, due to nerve traction over the coracoid notch during violent movement ("dunking" most probably). Clinically, he was unable to abduct his arm and had some difficulty in external rotation. He developed atrophy in both the supra- and the infraspinatus muscles. Nerve conduction latency to the supraspinatus muscle was 8.0 ms, and to the infraspinatus, 8.5 ms. The compound muscle action potential registered in the supraspinatus was 1.224 mV, and in the infraspinatus, 1.237 mV. After 3 weeks of inactivity, recovery was spontaneous and practically complete.
