[Moral and psychological violence at work: assessment and certification].

Mobbing constitutes a phenomenon not yet clearly defined. The activity, located in the H Faculty of Medicine and Surgery, is specifically dedicated to such phenomenon, which is the outcome of cooperation. The examined population is composed by a light prevalence of women (54%) respect to men (46%), aged around 44 years and employees (73%), workers (27%). All patients have been submitted to working anamnesis before being subjected to a psychiatric examination and psycodiagnostic tests. The emerged data underline a trouble of adaptation 63% of the cases (to which we have released a certification of compatibility with mobbing), 28% is affected by psychiatric pathologies, 9% of the patients do not show mental disorders. Nevertheless, it is necessary a connection between a physician and business medical service.

[Emergent pathology in occupational medicine: the mobbing].

Mobbing constitutes a phenomenon not yet clearly defined. The activity, located in the II Faculty of Medicine and Surgery, is specifically dedicated to such phenomenon, which is the outcome of cooperation. The examined population is composed by a light prevalence of men (51.3%) respect to women (48.6%), aged around 42 years and employees (71.6%), workers (28.4%). All patients have been submitted to working anamnesis before being subjected to a psychiatric examination and psycodiagnostic tests. The emerged data underline a trouble of adaptation 55.4% of the cases, 40.5% is affected by psychiatric pathologies, 4.1% of the patients do not show mental disorders. A certification of compatibility with mobbing has been possible to be verified in 49% of the cases. Nevertheless, it is necessary a connection between a physician and business medical service. We hope a necessary enactment of a specific regulation.

Age-related changes of neuro-endocrine-immune interactions in healthy humans.

Numerous interactions exist among the nervous, endocrine and immune systems, mediated by neurotransmitters, hormones and cytokines. The function of these systems shows patterns of circadian rhythmicity and a number of age-related changes in the 24-hour hormonal and nonhormonal rhythms have been found in older human beings. The aim of this study was to evaluate the presence of altered integration among the nervous, endocrine and immune systems in older adults. Cortisol, melatonin, thyrotropin-releasing hormone (TRH), thyroid-stimulatinghormone (TSH), free thyroxine (FT4), growth hormone (GH), insulin-like growth factor I (IGF-I) and interleukin 2 (IL-2) serum levels were measured and lymphocyte subpopulation analyses were performed on blood samples collected every four hours for 24 hours from seven healthy young subjects aged 36-58 years (mean age +/- s.e. 45.28 +/- 3.31) and from seven healthy old subjects aged 65-78 years (mean age +/- s.e. 68.57 +/- 1.91). There was a statistically significant difference between the groups in the observed values of CD20 (total B cells, higher in the young subjects, t = 2.48, P = 0.028) and CD25 (activated T cells with expression of the alpha chain of IL-2 receptor, higher in elderly subjects, t = -2.23, P = 0.045); DR+ T cells were also higher in elderly subjects, T=34.0, P=0.01). There was no statistically significant difference in the observed values of CD2(total T lymphocytes), CD4 (helper/inducer T cells), CD8 (suppressor/cytotoxic T cells), CD4/CD8 ratio, CD16 (natural killer cells), HLA-DR (B cells and activated T cells), TcR delta 1 (epitope of the constant domain of delta chain of T-cell receptor 1), cortisol, melatonin, TRH, TSH, FT4" GH, IGF-I, IL-2. In the group of younger subjects a clear circadian rhythm was validated for the time-qualified changes of all the factors studied, with the exception of CD16, FT4 and IL-2. In the group of elderly subjects a clear circadian rhythm was validated for the nyctohemeral changes of CD2 (with a phase delay of three hours), CD8, CD4/CD8 ratio, CD16, CD25 (in opposite phase), cortisol (with a phase delay of one hour), melatonin, TSH (with a phase delay of one hour) and GH (with a phase advance of one hour). The results of the current study show that aging is associated with enhanced responsiveness of the T cell compartment and alterations in temporal architecture of neuro-endocrine-immune system.
