A simultaneous-equations analysis of urban development: migration and industrial growth in Israel's new towns.

A simultaneous-equations econometric model is used to analyze the recent development of new towns in Israel. The focus is on the relationships among migration, industrial investment, employment, and other structural and policy variables affecting urban development. "Our results affirm the importance of economic opportunity, agglomeration effects, population socioeconomic and ethnic composition, and access in determining migration flows. At the same time, unemployment and investment indices are affected by local labor-market conditions, government incentives, and regional development effects as well as by population composition and migration flows. Policy implications of the analysis are considered."

Place-to-place migration in Israel: estimates of a logistic model.

"A multinomial logit model focusing on economic and other locational factors is formulated and applied to data on place-to-place migration in Israel. Results indicate the effects of expected industrial wage differentials, in accordance with the hypothesis of Harris and Todaro (1970), and of disparities in the structure of industrial employment, suggesting that perceived risk as well as expected return enter into the decision to migrate, as Stark and Levhari (1982) have argued. Other effects include those associated with regional differentials in amenities and agglomeration associated with urbanization, population mobility by age group, center-periphery migration trends, border security hazards, and the like. Implications of the analysis for the Israeli policy of population dispersion are discussed."

[Congenital fiber disproportion: atrophy of type I fibers. Report of 11 cases].

The authors report 11 cases of congenital disproportion of fibers, confirmed through clinical and complementary examinations. In these 11 cases early fibrotendinous retractions were frequent and CK proved to be high. At muscle biopsy histochemistry revealed a selective atrophy of type I fibers. This is a rarely frequent congenital dystrophy, of slow progression and benign evolution.

[Congenital progressive muscular dystrophy of Fukuyama type: report of a case].

The authors report the first Fukuyama type congenital progressive muscular dystrophy case described in Brazil, and confirmed through clinical findings and complementary tests. Emphasis is given to the presence of early fibrotendinous retractions and impairment of the central nervous system, which constitute the fundamental characteristics of this affection. This disease is very common in Japan but very seldom described in other countries. Its etiopathogeny has not yet been defined.

Israeli adolescents and military service: encounters.

Problems of mental health during combat activities are well documented in Israel (Dasberg, 1976). Much less attention has been paid to the problems of the young soldier who enters army life in Israel. This paper delineates some areas of friction and vulnerability between the worlds of the youth and the military. These encounters are systematized into groups, creating the "Binary Model." This model, based on the authors' experience as clinicians in the I.D.F. Central Mental Health Clinic, helps in locating and treating young soldiers in crisis situations.

Transcutaneous electrical nerve stimulation in experimental acute arthritis.

Transcutaneous electrical nerve stimulation (TENS) is applied for the relief of various types of pain, including rheumatoid arthritis and osteoarthritis. This study evaluated the influence of TENS on intraarticular (IA) temperature and pressure and synovial tissue of inflamed rabbit joints. Four hours after induction of acute bilateral hind joint arthritis by single intraarticular injection of urate crystals, the knees of 14 anesthetized rabbits were fixed at 90 degrees between femur and tibia. TENS was supplied from an electrical stimulator to the left knee joint while the other joint was unstimulated as a control. A microprobe needle for temperature measurement was inserted into the knee joint. Intraarticular pressure was recorded by polygraph connected to an IA needle. Readings were carried out at 10-min intervals three times before and four times after 5 min of TENS. A significant increase in IA temperature from mean 36.2C to 36.6C and significant reduction of IA pressure (mean decrease of 0.8 mmHg, from 2.5 mmHg to 1.7 mmHg) were found in the stimulated joints, which also showed a reduction of synovial fluid volume and total leukocyte count in comparison to the controls. While the nonstimulated synovial membrane showed massive leukocytic infiltration with neutrophilic exudate and fibrin clot in the intraarticular cavity, the stimulated synovial membrane demonstrated moderate homogeneous leukocytic infiltration through all layers, with absence of inflammatory exudate in the intraarticular cavity. These results suggested that the analgesic effect of TENS on arthritis may be partially attributed to decrease in IA synovial fluid pressure, volume, and leukocyte count. Therefore, TENS may be useful for reducing pain from inflammatory arthritis.

High-dose pulse chlorambucil in advanced, low-grade non-Hodgkin's lymphoma.

High-dose pulse chlorambucil was given orally at a dose of 16 mg/m2 daily for 5 consecutive days each month, as reported by Cadman et al. It was used to treat 33 patients with advanced, low-grade non-Hodgkin's lymphoma. With median follow-up of 4.2+ years, 70% of the patients achieved objective response. Eleven of 24 patients with follicular small cleaved cell lymphoma (FSCL) had pathological complete response; nine of 24 with FSCL and three of seven with small lymphocytic lymphoma had partial response. Median disease-free survival was 28 months. Actuarial survival for all patients was 60% at 5 years from initiation of therapy. Treatment toxicity was minimal. Pulse chlorambucil is an effective and minimally toxic palliative therapy for advanced FSCL.
