The relevance of the partial dynamical symmetry concept for an interacting fermion system is demonstrated. Hamiltonians with partial SU(3) symmetry are presented in the framework of the symplectic shell model of nuclei and shown to be closely related to the quadrupole-quadrupole interaction. Implications are discussed for the deformed light nucleus 20Ne.
The effect of trophotropic (relaxing) music on heart rate and heart rate variability has been investigated in 23 healthy young individuals by means of 24-hour Holter-ECG. Relaxing music (Bach, Vivaldi, Mozart) resulted in significant reduction of heart rate and also significant reduction of heart rate variability. The significance of these results for the use of music in coronary heart disease is discussed.
BACKGROUND: The purpose of the study was to analyze serologic and molecular markers of the GB virus type C/hepatitis G virus (GBV-C/HGV) infection in voluntary blood donors from Southeastern France. STUDY DESIGN AND METHODS: Sera were tested for the presence of GBV-C/HGV RNA by reverse transcriptase-polymerase chain reaction and that of antibodies to the GBV-C/HGV E2 (anti-E2) antigen by an enzyme-linked immunosorbent assay. A first cohort (1660 blood donors) was tested prospectively and a second cohort (238 samples with hepatitis markers) was tested retrospectively. Donors in the prospective study were questioned for possible risk factors of virus transmission. Amplification products were sequenced and subjected to phylogenetic analysis. RESULTS: Approximately 2.6 percent of individuals accepted for blood donation and 15.4 percent with positive hepatitis C virus serologic tests carried GBV-C/HGV RNA. Anti-E2 was detected in these two populations in approximately 12 percent and 48 percent of donors, respectively. Moderate relative risks were found only in tattooed or pierced individuals (1.82) and health care workers (2.45). Almost all strains were located in the same phylogenetic branch as HGV Group 2. CONCLUSION: Though a large proportion of the donors tested have been in contact with GBV-C/HGV, no elevated relative risk of infection was identified. The phylogenetic distribution of viral strains suggests that the infection is endemic in this population.

Based upon the findings of eosinophilia and concomitant ECG changes, hypersensitivity myocarditis was diagnosed in a patient who had been given longstanding antibiotic therapy. With cessation of drug treatment the disease resolved spontaneously.
Since December 1988 the district hospital of the Oberwallis hosts the 4 year project "Music-Therapy in Internal Medicine" under the scientific guidance of Dr. H. H. Decker-Voigt, director of the Institute of music therapy of the musical academy Hamburg. This therapy can be described as a form of psychotherapy which uses the medium music with its particularities as an adjunct for treatment. The different levels of action of music, a functional and a regressive one and their respective importance for music therapy are described first. An introduction to the two forms of music therapy, the receptive and the active with their respective particularities follows. Indications for music therapy are by large not disease-specific but depend on the assessment of the importance of psychic components in somatic disease. Coping with disease, psychosocial integration and promotion of positive resources or self-healing potential are regarded as indications for music therapy. Music therapy is not indicated when the patient is not motivated or his stay at the hospital is shorter than 2 weeks. We offer a music therapy to all patients in whose illness, according to our evaluation, emotional and psychic factors play an important role and to those patients with functional disorders on whom we would like to learn more by the psychoanalytic possibilities of music therapy. According to our experience music therapy is well suited as an adjunct in many diseases in internal medicine and represents an enrichment of our therapeutic possibilities.
As part of a project "Music therapy in internal medicine" we investigated 32 consecutive patients undergoing gastroscopy for various reasons. Patients were randomly assigned to two groups, regardless of sex, age or underlying disease. One group listened to music during gastroscopy, while the other did not. The choice of the type of music within the corresponding group was made with the patient and a trained music therapist in a short discussion prior to gastroscopy. The hormones ACTH and cortisol, as well as the catecholamines adrenalin and noradrenaline, were measured in both groups with three blood samples taken before, directly after and one hour after gastroscopy. Parallel measurements included blood pressure and pulse rate as well as questions about the patients' feelings during gastroscopy. The study showed the rise in the plasma levels of the stress hormones ACTH and cortisol to be significantly lower under the influence of music. The subjective feelings of the patients concerning "fear in general" and "fear about gastroscopy" paralleled these findings. Conversely, the plasma adrenalin and noradrenaline levels before and after gastroscopy were virtually unchanged in both groups, as were pulse rate and blood pressure. This study shows the influence of music on human biochemical parameters when used in the setting of a diagnostic procedure.
During implementation of a new Do-Not-Resuscitate (DNR) policy in New York State, decisions by 233 nursing home patients of their surrogates were evaluated. Eighteen patients with capacity (mean age +/- SD = 76.4 +/- 12.1 years) chose DNR; 30 patients with capacity (mean age +/- SD = 76.2 +/- 10.7 years) chose to be resuscitated (CODE); 54 patients without capacity, (mean age +/- SD = 86.1 +/- 9.1 years) had surrogates who chose DNR; and 131 patients without capacity and with surrogates (mean age +/- SD = 81.9 +/- 9.8 years) remained CODE. Most patients with capacity who chose DNR had multiple sclerosis, while most choosing CODE had strokes. Most patients who lacked capacity had dementia. Forty-five percent of surrogates did not respond regarding CODE status during the three-month study interval, and 10% wanted additional time to decide. Patient age appeared to be a factor in surrogate choice for DNR but not in patients with capacity making their own decision. Reasons for patients with capacity choosing DNR are discussed; perceived quality of life and premorbid feelings by patients help in the decision-making process.
In a multicentre, double-blind, parallel study performed in 78 hospitalized patients who complained of mild, moderate or severe insomnia, the efficacy and safety of 15 mg midazolam were compared with those of 15 mg oxazepam, both orally administered. The results showed statistically significant better results in the onset of sleep in the patients treated with midazolam. Other sleep parameters, such as quality and duration of sleep as well as the condition of the patients on morning awakenings, were also improved in more patients treated with midazolam. Safety (clinical and biological) was very good in both groups of patients.
