An interdisciplinary psychoeducation program for schizophrenic patients and their families in an acute care setting.

A psychoeducation program in an acute care inpatient psychiatric setting involves schizophrenic patients and their families in a range of educational interventions that are responsive to their particular strengths and vulnerabilities. Patients receive one-on-one instruction about their illness from a psychiatrist and the nursing staff and learn community living skills in classes and tutorials conducted by occupational therapists. Families discuss ways of coping with the patients' illness in a series of meetings with a social worker, and they attend workshops led by a team of clinicians and an administrator, who advise them of current perspectives on the illness and its management and about how to negotiate the mental health system. A mental health library keeps staff, family, and patients abreast of recent literature about schizophrenia. The authors believe the program prepares patients to live in the community better than do programs whose goals are limited to symptom reduction or crisis intervention.

Renal histology of mucocutaneous lymph node syndrome (Kawasaki disease).

Renal involvement is well described in patients with mucocutaneous lymph node syndrome (MCLNS), or Kawasaki disease and is manifested by mild azotemia, hematuria, pyuria or cylinduria, and more often, proteinuria. Renal morphology during the acute stages of the illness has never been reported. In this paper we describe the renal histopathologic changes in a child with MCLNS. The glomerular histopathologic findings suggest immune complex damage to the kidney as a possible mechanism of nephrotoxicity in MCLNS. Presence of kidney lesions, which speak in favor of the injurious role of immune complexes in MLCNS may be relevant to the understanding of the pathogenesis of the vascular lesions that are characteristic of this disease.

Self-insured health plans.

Nationwide, 8 percent of all employment-related health plans were self-insured in 1984, which translates into more than 175,000 self-insured plans according to our latest study of independent health plans. The propensity of an organization to self-insure differs primarily by its size, with large establishments more likely to self-insure. In the overwhelming majority of cases, the self-insured benefit was hospital and/or medical. Among employers who self-insure, 23 percent self-administer, and the remaining 77 percent hire a commercial insurance company, Blue Cross/Blue Shield plan, or an independent third-party administrator to administer the health plan.

Intratracheal thyroid: an unusual cause of upper airway obstruction in a newborn.

The proper management of upper airway obstruction requires prompt recognition, correct diagnosis, and appropriate treatment. Of all the causes of upper airway compromise, intratracheal thyroid is one of the least common, especially in the newborn. The majority of cases reported involve adults or adolescents, mostly in European countries. The English literature has fewer cases, none involving a newborn. The authors report a case they believe to be the first example in the English language of obstructing intratracheal thyroid in a newborn. The authors' experience and literature review of this rare anomaly are presented in an effort to acquaint others with this often unthought of cause of airway compromise.

Enhancing the usability of safety software for microcomputers.

With the proliferation of microcomputers, increasing effort is being made to write programs dealing with occupational safety and health. So as to assure the widespread use of this material, it is important that it be prepared in a manner easy to use. Ignoring this consideration may cause the potential users to be repelled by it from the start, or that its use will be difficult and error-prone. This article dwells on some of the points that need to be borne in mind when writing such software to make it easy and pleasant to use. Additionally, a project, carried out by the author, is described, which makes use of a free-form program access approach, as opposed to a purely menu-driven one. Two potential extensions of this approach are then described.

Serotonin-activated adenylate cyclase and the possible role of cyclic AMP in modulation of buccal muscle contraction in Aplysia.

The possible role of cyclic AMP in mediating opposite modulatory effects of serotonin (5-HT) on Aplysia buccal mass muscles E1 and E2 was examined. Serotonin enhances E1 contractions and inhibits E2 contractions. Adenylate cyclase in membranes of both E1 and E2 is stimulated approximately 180% by 10(-6) M 5-HT and 300% by 10(-3) M 5-HT. Dibutyryl cyclic AMP and 8-benzylthio cyclic AMP mimicked the effect of 5-HT on E1 but had no effect on E2. Theophylline (Th) and isobutylmethylxanthine (IBMX) mimicked the effect of 5-HT on E1 at high concentrations. Concentrations of Th and IBMX low enough not to have any direct effect on contraction increased both the magnitude and duration of the effect of 5-HT on E1 contraction. Neither Th nor IBMX had a direct effect on E2 contraction, although Th produced a small increase in the effect of 5-HT on E2. These data are consistent with the hypothesis that cyclic AMP mediates the enhancement effect of 5-HT on E1 contraction. Other mechanisms probably mediate the effect of 5-HT on E2 contraction.

The practice of occupational safety and health--facing the twenty-first century.

As a result of the increasing need for the services of occupational safety and health staff, with the concomitant costs, on the one hand, and rapid developments in the field of microcomputers, on the other, it was felt that a new conceptualization of safety practice, integral with computer use, was in order. To meet this objective, a microcomputer software package for interactive use by all levels of occupational safety and health practitioners, was prepared. The experience has indicated to the author that this is a viable and worthwhile approach, giving promise of enhancing the performance capabilities of lower level staff, and saving the time and effort of highly qualified practitioners.

Campylobacter enteritis in infants and young children.

Campylobacter has recently been recognized as a common pathogen of the intestinal tract in pediatric practice. We report on 21 patients who were diagnosed as having enteritis due to Campylobacter jejuni infection. The most common symptom was diarrhea, accompanied by fever, vomiting and abdominal pain. The in vitro sensitivity test demonstrated the efficacy of aminoglycosides, chloramphenicol and erythromycin in the treatment of this disease. All the patients were symptom-free when discharged from the hospital.

Ambient air concentration of sulfur dioxide affects flight activity in bees.

Three long-term (16-29 days) low-level (0.14-0.28 ppm) sulfur dioxide fumigations showed that exposure to this gas has deleterious effects on male sweat bees (Lasioglossum zephrum). Although effects on mortality were equivocal, flight activity was definitely reduced. Because flight is necessary for successful mating behavior, the results suggest that sulfur dioxide air pollution could adversely affect this and doubtless other terrestrial insects.

Linkage analysis between the major histocompatibility system and insulin-dependent diabetes in families with patients in two consecutive generations.

We have histocompatibility (HLA) genotyped 28 families with insulin-dependent diabetics in two or more consecutive generations, usually parent and child. This strategy of ascertainment was used to maximize the likelihood of obtaining a homogeneous type of disease within a family, and an autosomal dominant mode of inheritance. 76 diabetics and 169 nondiabetics were studied in these families. The frequencies of the antigens Dw3 and Dw4, and the genotype Dw3/Dw4 among the diabetics are 59, 68, and 30%, respectively, as compared with 15, 12, and 2% in normal controls, and 43, 41, and 10% in the nondiabetic relatives of the diabetics. Dw2 is present in only one diabetic (4%), as compared with 18% in normal controls and 17% in nondiabetic relatives.HLA haplotype concordance was analyzed for sib pairs in relation to the haplotype shared by the affected parent/child pair, and for the diabetic sib pairs within each sibship. The results failed to reveal deviations in the expected HLA haplotype assortment. Assuming an autosomal dominant mode and several penetrance levels, linkage analysis between the HLA and diabetes was performed. The total lod score is 0.37 for a recombination fraction of 0.29 at 50% penetrance. Although the linkage and concordance analysis results are inconclusive, they seem to be different from those reported by us for families with normal parents and two or more diabetic sibs. Because ascertainment biases may have influenced these results in an unquantifiable manner, it is not certain whether the two types of families are genetically different. However, the marked difference in the lod scores for the 50% penetrant autosomal recessive model between the two types of families is compatible with a genetic dissimilarity between them. The high frequency of the Dw3 and Dw4 antigens, the Dw3/Dw4 genotype, and the decreased frequency of Dw2, however, indicate the existence of two or more important diabetic genetic factors associated with the D region of the HLA in these families.
