Alcohol and psychoactive drug use among Israeli adolescents: an epidemiological and demographic investigation.

One thousand nine hundred Israeli adolescents--51.8% males and 48.2% females--aged 15 to 18, were questioned twice about their current and "ever" substance use. The first study was undertaken during September-October 1982 and the second about a year later. The findings clearly indicated a slight rise in the incidence and a moderate growth of the prevalence of substance use among Israeli adolescents. The relationships between substance use and several background sociodemographic variables that were studied are discussed.

Personality core dynamics and drug preference.

The aim of this study is to investigate the possible link between Shoham's personality-core theory [1] and addiction to hard drugs. Basing ourselves on Kleinean premises, that the oral stage is critical in the formation of behavioural patterns, which are influential throughout life, we hypothesize that in the oral stage two opposing vectors, 'separation' and 'participation' are initiated. By 'participation' we refer to the identification of ego with an external object or symbol, and continuous tendency to lose the personal identity by fusion with this object or symbol. 'Separation' is the opposite vector and expresses ego's tendency to incorporate the external object or symbol. These vectors form two multidimensional personality axes, on which the different personality types and behavioral patterns can be anchored. This study aims at investigating the connection between these two vectors and drug addiction. We view drug addiction as a functional behaviour pattern, which brings the individual to a state of internal balance. Shoham's personality theory hypothesizes the derivation of behavioural patterns of different personality 'types', according to the strength of the two vector - the 'separant' and 'participant' types. It is hypothesized that the drug use and the experience gained by using the specific drug by different personality types will vary according to the prominence of the core personality vector. The potency of these vectors is related to an early oral (participant) or a later oral (separant) fixation.(ABSTRACT TRUNCATED AT 250 WORDS)

Polar types of reported drug involvement among Israeli youth.

The predisposing factors lined to drug involvement may be different for various types of youth, although the outcome is the same. In this sense a bimodal curve of drug involvement would indicate two types of highly involved youth: on the one hand, those from high social status families where low parental control implies a tendency to seek involvement with their peers and solve their personal adjustment problems within the peer group. On the other hand, those from the lower social strata for whom low parental control also implies association with outside peer groups as an alternative to shaky and diffuse families and lack of involvement in school life. This study on the cannabis involvement of 776 boys and girls (aged 14-18), drawn from eight schools, is an attempt to identify and describe these polar types of drug-involved youth in more detail.

Some parameters of the use of alcohol by Israeli youth and its relationship to their involvement with cannabis and tobacco.

This is the third report of an epidemiological study dealing with drugs, cigarettes, and now alcohol, amongst secondary school students in Israel. In the present report we describe general trends of alcohol use, draw socioeconomic profiles of alcohol drinkers, and investigate the relationship with cannabis use and cigarette smoking. Drinking patterns of the research population were studied during the 30 days prior to the administration of a questionnaire in order to devise a scale of their quantity of drinking in relation to a time sequence. Measures were also constructed for the drinking patterns of the family and friends of the research population. One of the overall conclusions is that a higher alcohol consumption is indicated amongst youngsters with a profile of delinquency, involvement with youth activities, personal problems and low parental control.

Postmenopausal pneumococcal tubo-ovarian abscess.

Streptococcus pneumoniae is an uncommon cause of infection in the female genital tract. An unusual case of postmenopausal pneumococcal tubo-ovarian abscess is presented. The pathogenesis of this infection probably entailed the ascent of bacteria from the vagina to the internal genitalia; there was no evidence of infection of the bloodstream or gastrointestinal tract.

Necrotizing choroiditis-retinitis as presenting symptom of disseminated aspergillosis after lung transplantation.

BACKGROUND: Endogenous endophthalmitis due to Aspergillus is rare affecting the severely immunosuppressed population, in particular recipients of heart and lung transplants. Ocular involvement of aspergillosis has always been observed late in the course of the disease. SUBJECT: A young woman noted blurred vision in one eye three weeks after lung transplantation. At this stage, no systemic manifestations of fungal infection were detected and the ocular findings were attributed to viral infection. RESULTS: Twenty-four hours after the original ocular complaint, an aggressive endophthalmitis developed in the left eye. The possibility of fungal endophthalmitis was raised. Within 48 hours of her first ocular complaint the patient died. Cultures from a vitreous tap and from autopsy ocular specimens were positive for Aspergillus fumigatus. CONCLUSIONS: Aspergillus endopthalmitis may occur in patients undergoing lung transplantation despite antifungal therapy. Increased awareness of this unusual entity may be life and vision saving in these patients.

Differential patterns of drug involvement among Israeli youth.

The present study tries to link some demographic, social, psycholoogical and attitudinal variables of drug abuse. The findings were centred around the readiness of secondary school youth in Israel to be involved in drugs and their active searching for drug involvement. A dependent variable based on five indices of drug involvement was constructed. It was then related to parental control, peer involvement in drugs, sex differentiation and membership in youth movements. A bi-modal high involvement curve was found, the first mode consisting of youth of low socio-economic strata who are drop-outs, who associate with outside peer groups as an alternative to their shaky and diffused families and lack of involvement in school life. The other mode consists of youth with a higher socio-economic background who are involved with drugs due to their desire for new hedonistic and emotional experiences. Their openness to experiment with drugs is a corollary to their involvement within a peer group which condones and legitimizes narcotics as well as any experiences which irrespective of their source, provide "a good high". There is a sub-group within this group which would be involved with drugs as a partial escape from personal problems.
