Changes of consultation-liaison psychiatry practice in Italian general hospitals: A comparative 20-year multicenter study.

Introduction: Conducted under the auspices of the Italian Society of Consultation Liaison Psychiatry (SIPC) the aim of this study was to describe the characteristics of Consultation Liaison Psychiatry (CLP) activity in Italy (SIPC-2-2018) over the past 20 years by comparing with data from the first Italian nation-wide study (SIPC-1-1998).

Methods: We collected data on CLP visits of 3,943 patients from 10 Italian hospitals over a period of 1 year. Data were compared with those from the SIPC-1 1998 study (4,183 participants).

Poor sleep quality may contribute to dysfunctional illness perception, physical and emotional distress in hospitalised patients: results of a national survey of the Italian Society of Consultation-Liaison Psychiatry.

Distress associated with physical illness is a well-known risk factor for adverse illness course in general hospitals. Understanding the factors contributing to it should be a priority and among them dysfunctional illness perception and poor sleep quality may contribute to it. As poor sleep quality is recognised as a major risk factor for health problems, we aimed to study its association with illness perception and levels of distress during hospitalisation.

Development and validation of the Greek severe impairment battery (SIB).

Background: Most neuropsychological batteries, especially those most often used, are unsuitable for the assessment of patients with severe dementia. The Severe Impairment Battery (SIB) was developed for the evaluation of preserved cognitive functions in these patients. The aim of this study was to formulate a Greek version of the SIB and to conduct a first assessment of its use of patients with mild, moderate, or severe Alzheimer's disease (AD), compared to the Mini-Mental State Examination (MMSE).

Ultradian variation of nerve growth factor plasma levels in healthy and schizophrenic subjects.

Some studies in animal models showed that several neurotrophins may be implicated in the regulation of light-dependent suprachiasmatic pacemaker and in other functions implicated in long-term memory acquisition during sleep. However, no data are known about the role played by NGF in ultradian regulation in humans. The aim of this study was to investigate whether or not there is a natural diurnal fluctuation during daytime in healthy and schizophrenic subjects with a normal light/dark cycle.

Severity of obstetric complications and risk of adult schizophrenia in male patients: a case-control study.

Objective: Obstetric complications may be an etiologically important factor in the development of schizophrenia. The aim of this study was to evaluate whether the risk for developing schizophrenia in adult life is increased in individuals with more severe obstetric complications at birth.

Methods: To this end, mothers were interviewed to gather data about obstetric complications.

Reduction of night/day difference in melatonin blood levels as a possible disease-related index in schizophrenia.

Objective: Aim of this study was to verify if a simple index as night-day plasma MLT level variation is able to confirm the existing data on circadian melatonin alterations in schizophrenia and if a relationship to disease itself instead of the actual clinical state can be suggested.

Setting And Design: Ten consecutively admitted male schizophrenic inpatients were examined.

Methods: The blood samples for melatonin were collected at 3.

Reduced pineal volume in male patients with schizophrenia: no relationship to clinical features of the illness.

Several investigations have suggested pineal gland abnormalities in the pathogenesis of schizophrenia. The pineal volume on brain magnetic resonance imaging scans was calculated in 15 male schizophrenic inpatients and in 16 matched control subjects. The statistical comparison found a significant difference of pineal gland volume between schizophrenics and controls (P = 0.

Data and hypotheses on the role of nerve growth factor and other neurotrophins in psychiatric disorders.

Nerve growth factor (NGF) was discovered and characterized for its role on the growth, differentiation and maintenance of specific neurons of the peripheral nervous system. Subsequent studies revealed that NGF is synthesized and released within the central nervous system and exerts a trophic and functional role on basal forebrain cholinergic neurons; it is involved in a protective role following brain insults induced by an epileptic status, seizure, as well as surgical and chemical lesions.More recently our collaborative studies provided evidence that NGF is implicated in neurobehavioral response including cerebral alterations associated with psychiatric disorders.

Computed tomography study of pineal calcification in schizophrenia.

Computed tomography studies concerning pineal calcification (PC) in schizophrenia have been conducted mainly by one author who correlated this calcification with several aspects of the illness. On the basis of these findings the aim of the present study was to analyze size and incidence of pineal gland calcification by CT in schizophrenics and healthy controls, and to verify the relationship between pineal calcification and age, and the possible correlation with psychopathologic variables. Pineal calcification was measured on CT scans of 87 schizophrenics and 46 controls divided into seven age subgroups of five years each.

Choroid plexus calcification as a possible clue of serotonin implication in schizophrenia.

Choroid plexus calcification (CPC) was measured on computed tomography (CT) scans of 87 schizophrenics and 46 controls divided into age subgroups. We studied the relationship between presence and size of CPC and age in both groups, whilst in the schizophrenic group we also investigated the possible correlation between CPC size and age of onset and duration of illness, duration of formal education, psychopathological features of the illness as well as some neuroradiological brain measures. CPC size correlated with age in healthy controls but not in schizophrenics.
