[Medicolegal aspects of chronic alcoholism. Considerations on the behavior of 285 chronic alcoholics].

The Authors examined 285 male sex chronic alcoholics hopitalised in the Psychiatric Clinic of Parma University from 1969 to 1974. Clinical diagnosis, family anamnesis, degree of learning, civil status, beginning of abuse of alcoholics were considered. The Authors then, made a research at the Criminal Court records-office to verify how many of these alcoholic patients had committed crimes, what kinds, how many, related particularly to single subject's personality.

Inhibitory cerebellar circuits: GAD immunoreactivity in the frog cerebellum.

The presence of GABAergic structures in the frog cerebellum with simple nervous circuits was investigated with an immune serum raised against glutamic acid decarboxylase (GAD). GAD immunoreactivity is detectable in all the cerebellar layers. The most obvious difference in comparison with mammals is the scarcity of GAD-positive terminal boutons on Purkinje cells and this is consistent with neurophysiological data indicating that the inhibition on frog Purkinje cells is weaker than in mammals. However, there are numerous GAD synapses on cerebellar and vestibular nuclei. A large number of GAD immunoprecipitates are present in the molecular and granular layers, though their morphological organization is different from that in mammals. In the upper part of the molecular layer GAD immunoreactive cells and fibres form a plexus-like structure and in the internal granule layer immunoreactive varicosities are not arranged in the ring-like assemblies of mammals.

[Morbidity and mortality in a resuscitation center: pathological aspects of cases without medico-legal relevance].

The authors studied, in the light of a more detailed research on the pathology of reanimation, the morbility and mortality rates in a Reanimation Centre taking into account different parameters: they evaluated the incidence of recoveries in this ward over 5 years, in relation with that obtained in the relative Regional Hospital. They subdivided patients suffering from "natural" morbid processes from those suffering from "medico-legal kind of diseases; this was done taking into account age, sex and clinical progress of the diseases. After ward they analysed more specifically 131 cases of death in that ward in the light of the clinical evolution and the consequent autoptic examination. The Authors subdivided finally the cases into four main pathological classes, formulating observations of pathogenetical interest.

[Suicide in the hospitals of Parma in the 30-year-period of 1944-1973].

The Authors consider the cases of suicide which took place in the hospitals of Parma from 1944-1973 (41 cases) examining them from several aspects: age, sex, civil status, season and day's hour when the death occurred, means, anamnesis, the disease which caused the admission to hospital, time spent in hospital, autopsy results. They also make medico-legal and criminalistic observations about the pertinent data.

Why do benign paroxysmal positional vertigo episodes recover spontaneously?

It is well known that most episodes of benign paroxysmal positional vertigo (BPPV), even in untreated, recover spontaneously in 2 to 6 weeks. In the present study, we put forward the hypothesis that this is mainly due to the fact that endolymph, owing to its low calcium content (20 microM) is able to dissolve otoconia. To support this, the fate of frog saccular otoconia immersed in normal endolymph (Ca2+ content 20 microM) and in Ca2+-rich endolymphatic fluids (up to 500 microM) was studied by observing the crystals at regular intervals for 3 weeks. The results demonstrated that normal endolymph can dissolve otoconia very rapidly (in about 20 hours). When the endolymphatic Ca2+ content was increased (50 to 200 microM) otoconia dissolution time was slowed down (about 100 to 130 hours, respectively) and completely stopped when the endolymphatic Ca2+ content was of 500 microM. The present results therefore suggest that the major process involved in the spontaneous recovery of BPPV episodes is the capability of the endolymph to dissolve dislodged otoconia.
