Follicle-stimulating hormone (FSH) is considered to be the most important plasma hormone correlated with spermatogenesis. Elevated FSH plasma levels were shown to be associated with complete damage to testicular seminiferous tubule germinal epithelium. Recently, there have been conflicting reports with regard to the value of FSH plasma levels in predicting seminiferous tubule histology in the azoospermic patient and hence, as a guide for therapy in assisted reproduction using testicular sperm retrieval. The aim of this study was to evaluate whether FSH plasma levels can predict spermatogenic pattern in the testes of the azoospermic infertile patient. 69 infertile men with non-obstructive azoospermia and 18 with very severe oligospermia were studied. In all, plasma levels of testosterone, free testosterone, prolactin, luteinizing hormone and follicle-stimulating hormone were measured by enzyme immunoassay. In the azoospermic patients the seminiferous tubule spermatogenic pattern was determined in testicular aspirates obtained by multiple fine needle aspiration and categorized according to the most mature spermatogenic cell type in the aspirates: Sertoli cells only, spermatogenic maturation arrest or full spermatogenesis. There were no significant differences in plasma levels of any hormone measured except in very severely oligospermic and azoospermic patients. Both normal and elevated levels were detected in all, regardless of seminiferous tubule cytological pattern or plasma FSH in azoospermic patients. It is concluded that plasma levels of FSH can not be used as a predictive parameter, neither for the presence of spermatozoa nor for any other seminiferous tubule cytological pattern in azoospermic infertile men. They cannot serve as guides for selection of azoospermic men for trials of testicular sperm retrieval in assisted reproduction.

Israel has absorbed many immigrant physicians and has utilized their skills without compromising local professional standards. In accordance with this policy a special law for the assessment of the licensing of senior immigrant physicians, mainly from the former Soviet Union, who had practiced medicine for at least 14 years was implemented in 1994.

Considering their considerable medical experience on the one hand and their lack of experience in speaking Hebrew or undergoing testing techniques, they were exempted from the written national licensing examination. Instead they were obliged to undergo a 6-month clinical observation period in a local hospital or clinic.

At the end of this period a letter of confirmation was issued which was followed by an oral assessment of their clinical ability. In the assessment session, each candidate was presented with written presentations of 4 typical clinical cases which practitioners encounter on a daily basis, in family medicine, emergency medicine, surgery, and pediatrics or gerontology. Of 114 cases prepared, 4 were selected for each candidate by the committee of 13 trained, experienced Israeli physicians.

3 members of the committee assessed each candidate using specified criteria. The assessment, which lasted about an hour, focused on the candidates' professional knowledge involved in differential diagnosis and case management.

Of 497 candidates examined between 1994 and 1996, approximately 80% passed in their first attempt. However, about 30% of the invited candidates did not appear for the exam. Characteristics of successful candidates were being young and being among the seniors with the least clinical experience. Most had specialized in internal medicine and had completed their observation period in a non-academic hospital. There they had received somewhat more attention than those who had been in academic hospitals. Significantly, the successful candidates were more proficient in Hebrew than the unsuccessful candidates, and reported no special problems during the observation period.

Splenic artery aneurysm is an uncommon form of vascular disease of unknown etiology. Its clinical importance is due to its high mortality, especially in pregnancy, when maternal mortality is 70% and fetal mortality 95%. Most cases of splenic artery aneurysm are asymptomatic and are diagnosed incidentally. We present a woman with incidentally diagnosed splenic artery aneurysm in whom the splenic artery and its aneurysm were resected.

The relationship between parturients' sociodemographic characteristics and the tendency of the medical staff to offer and of the parturients to accept intrapartum epidural analgesia, was investigated. 97 Jewish parturients were interviewed during January 1996. Multiple logistic regression analysis was used to evaluate the statistical significance of the results. 10 parturients (10.3%) asked for intrapartum epidural analgesia, and while 46 (47.4%) were offered it, only 22 (22.7%) accepted. Epidural analgesia was mostly offered to, and accepted by: low birth-order parturients (1st-3rd delivery), those belonging to the upper middle class, and to parturients with higher compliance with prenatal diagnostic tests. There was no significant association between the tendency of the medical staff to offer epidural analgesia to secular as compared to traditional parturients.

We conclude that the use of intrapartum epidural analgesia is related to various maternal sociodemographic characteristics. If the low compliance with epidural analgesia is related to prejudice and unfounded fears, we recommend that the benefits of this type of analgesia be explained before birth in the antenatal clinics.

Acute appendicitis is the most common surgical problem in pregnancy, when it is difficult to diagnose early because of the physiological changes of pregnancy. We studied the problem in the Negev population and present the main issues in diagnosis and management. Between 1988-96, 26 women were operated on for acute appendicitis during pregnancy (1/3297 deliveries), 3 by laparoscopy. In 13 there was a histopathological confirmation of the diagnosis. Clinical diagnosis was more accurate in the first trimester of pregnancy than in the second or third (p=0.073). Premature delivery rate was higher in both confirmed and unconfirmed acute appendicitis than in other pregnancies (p<0.00001), but without significant differences between the 2 groups with appendicitis. Other indexes of maternal and perinatal morbidity did not differ either.

This study compares Israeli primary care physicians with those of European countries. In Israel a larger proportion of those in primary care are women. The Israeli physicians see many patients a day, but almost never make home visits. They also report for work the fewest hours a day, but spend 21 hours a month in continuous medical education. (more than Europeans?) The Israeli primary care physician scores high in screening for breast cancer and blood cholesterol level, but very low in the fields of minor surgery and alcohol and smoking prevention, contraception, nutrition counseling and normal pregnancy follow-up. Residency training and education may be inadequate, and more emphasis has to be put on the health system and recognizing environmental influences.

Acute hyperparathyroidism is a rare and dangerous condition. It is supposed to result from transformation of a mild chronic form into an acute and stormy illness. The causes and the mechanism of such a transformation are usually unknown. A case of acute hyperparathyroidism is presented in which hemorrhage into a parathyroid adenoma was recognized and diagnosed as the immediate cause of the transformation from the mild long-standing form of the disease into the severe acute form.

In recent years there have been tremendous efforts to improve primary trauma care. The Ministry of Health and other authorities have invested in new trauma facilities in various hospitals. A nationwide survey with regard to structure and function of emergency departments was carried out. Compared to a similar survey conducted in 1992, significant progress in quality and quantity of equipment at various emergency departments was demonstrated. However, there are still differences between various hospitals. A drive to standardize trauma care will undoubtedly contribute to improvement in care of the injured.

We sought firsthand data on the extent of perceived mental health needs and on patterns of use of mental health services among Israelis aged 22 and over. The data are from a national survey conducted in 1995. A random sample of phone numbers from the telephone company's computerized listings yielded 1,395 completed questionnaires (response rate, 81%).

At some point in their lives, 27% had experienced emotional distress or mental health problems with which they had difficulty coping alone; 13.4% reported that they had such an experience during 1995. According to multivariate analysis, those more likely to report mental health problems were women, those with a chronic disease, Russian immigrants, divorced or widowed adults, those with a low level of education, and members of the Clalit sick fund. 38% of those who had ever had emotional or mental health problems had asked for help. The proportion of those seeking help was high among respondents aged 35-55, Hebrew speakers (compared to speakers of Russian or Arabic), and city dwellers, and the rate was low among members of the Clalit sick fund. Of those who did seek help, 39% went to a psychologist or a psychiatrist, 25% to their family doctor, 19% to a family member or friend, 7% to a social worker or social service agency, 6% to other medical personnel, and 4% to a psychiatric hospital. 30% turned for assistance to the private sector and 70% to the public sector.

These findings have special significance in view of the impending reform of the mental health services. As mandated by the new National Health Insurance Law, mental health services are to be included in the basket of health services provided by the sick funds. The data can be of use in the management of sick funds and for physicians working in the community, as they prepare for this change. In addition, the data will be of aid to national policy makers in planning services suited to the needs of different population groups and to allocate resources more rationally.

Medical Dept., Israel Defense Forces and Israel Trauma Society

In recent years a vigorous effort has been made to improve quality of primary trauma care in Israel. Advanced trauma life support courses (ATLS) were given to physicians throughout the country, regardless of their specialties. In 7 years 4229 physicians participated in 202 courses with an average success rate of 76%. In the future, issues such as mandatory vs. voluntary training, language barriers, and continuous decline of knowledge should be addressed if momentum is to be maintained.

The object of this study was to characterize those who leave the emergency department agmedical advice and to examine the short-term consequences. The study was conducted retrospectively 1992 and prospectively during May-August 1993 by telephone interviews. About 0.5% of all the patients who applied to the emergency department left against medical advice. Their main characteristic was that they were mostly young, single men. A wide range of complaints had brought them to the emergency department, very similar to that of the control group, but with a higher tendency to abuse drugs and alcohol. Most of those who left against medical advice had less severe disease than the controls. However 10% of them had to be hospitalized within the subsequent 2 weeks, in comparison with 4% of the controls. This study suggests that improving the efficiency of the emergency department will decrease the number leaving against advice.

During 1987-1996, 39 of 720 patients hospitalized (most for severe schizophrenia) were diagnosed as having active pulmonary tuberculosis (5.4%, 975 per 105 per year). In 1992-1993, after a cluster of 5 cases was found, all patients were screened by PPD skin test and chest X-ray and 16 more cases were identified. Diagnosis was confirmed bacteriologically in only 10 of them but there were typical radiological findings in the others. 39 were treated with a multi-drug regimen. In addition, 333 exposed patients and 21% who had converted their skin tests were given isoniazid preventive therapy. A small increase in levels of liver enzymes was common, but significant abnormality (over 4 times the upper limit of normal) was found in only 7 patients, in whom therapy was therefor stopped or changed. During a follow-up period of 4 years, 2 more developed tuberculosis and 33 converted their PPD reactivity status. We conclude that an outbreak of tuberculosis in a psychiatric hospital can be controlled with a relatively low rate of side-effects by using systematic diagnostic and therapeutic measures. However, single step screening is not sufficient. Routine screening of all new patients, a high index of suspicion and contact investigation are needed.

During craniotomy, the patient's cooperation is needed during procedures in which continuous neurological examination and mapping of crucial regions close to the area to be resected area are required. We report our experience in 9 patients who underwent such procedures under intravenous propofol as the main sedating agent. This short-acting hypnotic was administered prior to and during the painful stages of the procedure. Patients were fully asleep when the skull was opened and the dural flap raised or excised. During the rest of the operation patients were lightly sedated but remained responsive and cooperative. This enabled precise intra-operative mapping of the brain and surgery-related neurological deficits were avoided. Respiratory depression or hemodynamic compromise were not encountered. All patients were comfortable during the operation and there were no additional neurological deficits after operation. We believe that propofol should be the main sedating agent used for these procedures.

Senior surgeons were asked about mandatory participation of general surgery residents in the advanced trauma life support (ATLS) course. Although trauma care in Israel is given by surgical residents, in the opinion of their senior mentors the course should continue to be mandatory for them.

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.
