Prevalence of Polysubstance Abuse and Dual Diagnosis in Patients Admitted to Alcohol Rehabilitation Units for Alcohol-Related Problems in Italy: Changes in 15 Years.

AIMS: Alcohol abuse has long been known as a disease with social and economic burden to society. Given the complex nature of alcohol treatment, it is worthwhile to examine the change over time of patients admitted to residential alcohol abuse rehabilitation units. METHODS: The data were collected from two Italian projects on alcoholics performed in the mid-1990s (ASSALT) and in 2009 (CORRAL), respectively. Categorical variables were considered in terms of absolute and relative frequencies. Comparisons of relative frequencies between groups were assessed by means of Fisher's exact test. Mixed logistic regression models were fitted to CORRAL data to identify the predictors of the probability of being a polysubstance abuser or having a dual diagnosis. The association estimates were reported as adjusted odds ratios and relative 95% confidence intervals. RESULTS: Compared to the mid-1990s, in 2009 patients were older (P= 0.0003), with a higher level of education (P= 0.0204), with fewer comorbidities (liver disease except cirrhosis, P < 0.0001; polyneuropathy, P= 0.0001), more frequently polysubstance abusers (P < 0.0001), affected by dual diagnosis (P < 0.0001). In 2009, the probability of being a polysubstance abuser was higher in younger and in patients with dual psychiatric diagnosis. Female gender and polysubstance abuse were positively associated to the probability of being affected by dual psychiatric diagnosis. CONCLUSIONS: The increment of patients admitted to residential programs for alcohol dependence with polysubstance abuse and/or dual psychiatric diagnoses suggests the need to pay more attention to both psychological/psychiatric interventions and internal medicine/physical rehabilitation. SHORT SUMMARY: The results of this study suggest that further research is needed to identify the best treatment strategy that is safe and effective for the new population of alcoholics.

[Alcohol-addiction inpatient: characteristics of patients and rehabilitation program]. / La residenzialità alcologica ospedaliera: caratteristiche dei pazienti e dei percorsi terapeutici/riabilitativi.

AIM: The treatment of alcohol addiction in Italy has had a progressive evolution of therapeutic structures for in-and outpatients. During the last 20 years there had been a crescent presence of short residential treatment facilities (1-6 months) characterized by a high level of medical and psychotherapeutic intervention. About two years ago 12 of them jointed together in an association called CORRAL (COordinamento of Residenzialità Riabilitive Alcologiche). The aim of this study was to describe the socio-demographic medical and other characteristics of the patients coming for this type of treatment and to describe the characteristics of the residential treatment itself including referring and aftercare. METHODS: Two thousand sixty-one hospitalized patients of the 12 rehabilitative alcohol units were examined by using a questionnaire and collecting various sociodemographic variables and clinical diagnosis of the patients. Even it was asked who had referred the patients, the characteristics of the residential treatment and of the planned aftercare. RESULTS: The present residential facilities are mainly distributed in the North of Italy. The typical patient is male, with a high school instruction and with a comorbidity regarding psychiatric and liver disorders. The majority of the patients were referred by the public ambulatory services for addictions (SerT/SerD). The characteristics of the residential treatment were medical, pharmacological and psychotherapeutic interventions with a high intensity and the presence of a general-purpose staff. CONCLUSIONS: This study outlined a model of residential rehabilitation of alcohol disorders characterized by short duration and a complex, intense therapeutic intervention mainly addressed to patients with a severe clinical condition and a low level of social problems. Further research should be useful to understand better which sort of patient characteristics obtain a better clinical result and for that even economically a major effectiveness from this type of residential treatment.

Peroneal muscular atrophy with hereditary spastic paraparesis (HMSN V) is pathologically heterogeneous. Report of nerve biopsy in four cases and review of the literature.

Peroneal muscular atrophy (PMA) associated with hereditary spastic paraparesis (HSP) is a nosologically ill-defined disease, which has been classified by Dyck as hereditary motor and sensory neuropathy type V (HMSN V). Nerve biopsy has been rarely reported in this condition. We examined sural nerve biopsies in four patients, demonstrating the following: severe myelinated fiber loss especially of large fibers, with moderate (one case) or prominent (one case) onion bulb formation; selective decrease of large fibers with moderate Schwann cell hyperplasia (one case); normal myelinated fiber population with minimal changes (one case). After reviewing previously reported cases we, conclude that in PMA with HSP sural nerve biopsy may show features either of hypertrophic type of PMA, of neuronal type, or of spinal type; thus, it seems inappropriate to allocate PMA with HSP in a unique subtype of HMSN. In addition, HSP may be not associated with peripheral neuropathy, and thus the classification in the HMSN group may be incongruous. A proper classification of PMA with HSP may be in the "complicated" forms of HSP according to Harding [Lancet I: 1151-1155 (1983)]; however, the nosology of this condition needs to be further elucidated, possibly on the basis of the underlying molecular genetic mechanisms of HSP and PMA.

Cluster headache. Recent developments in clinical characterization and pathogenesis.

The preliminary results of some new studies on cluster headache (CH) point to: (a) the existence of a form, secondary episodic CH, which should be included in the classification of headache; (b) the significant role played by air temperature variations and the number of daylight hours on the onset of CH active periods. Data from the evaluation of pupil response to corneal stimuli suggest a widespread alteration of the pain/autonomic integrative processes at the level of the central nervous system. Finally, data on new preventive (i.e., verapamil and ozone) and symptomatic (i.e., hyperbaric oxygen and sumatriptan) treatments are reported.

[Headaches and craniofacial pains with dental involvement in the classification of the International Headache Society (1988)]. / Cefalee e algie cranio-facciali di interesse stomatologico nella classificazione della International Headache Society (1988).

Facial pain often presents complex diagnosis, requiring other specialists' consultation. The use of different terminology and protocols can affect the information exchange negatively. These problems in the field of headache, cranial neuralgias and facial pain lead the International Headache Society to introduce a new classification in 1988. The chief difference with the previous ones is the presence of strictly codified diagnostic principles. Its target is research, but it can help the general practice as well. We discuss the most interesting points to the stomatologist.
