A growing importance has been placed on the recognition and supervision of non-motor features of Parkinson's disease (PD). Depression has been estimated to affect one in three individuals with PD and can lead to worse health outcomes and decreased quality of life. Anxiety, apathy and anhedonia further complicate PD outcomes. In this double-blind, placebo-controlled trial, participants (individuals with mild to moderate PD; n = 24) were randomly assigned to treatment (800 mg/d docosahexaenoic acid (DHA) and 290 mg/d eicosapentaenoic acid, a precursor to DHA) or placebo (an equicaloric amount of corn oil). Treatment duration was 6 months. Treatment had no statistically significant effect on rate of change on either Unified Parkinson's Disease Rating Scale or Hoehn-Yahr Scale score. However, 75% of DHA-treated patients, reduced Hamilton Rating Scale for Depression total score by at least 50%, compared with only 25% into the placebo group. At the end of the six-month study, DHA integration reduced the depressive symptoms.

Anhedonia is present in Parkinson's Disease (PD) as well as in addictive behaviors. Pathological Gambling (PG) and other Impulse Control Disorders (ICDs) have emerged as iatrogenic complications associated with dopamine replacement therapy. We studied 154 PD patients, divided into three groups: 11 with PG, 23 with other ICDs (compulsive buying, hypersexuality, binge eating), 120 without ICDs. All patients underwent a thorough clinical, neuropsychological and psychiatric evaluation. The PG-group, compared to the ICDs-group and PD-controls, reported a significantly higher incidence of anhedonia (45% vs. 9% vs. 14% respectively), higher Snaith–Hamilton Pleasure Scale (SHAPS) scores (2.0±1.3 vs. 1.0±1.1 vs. 1.0±1.2), higher levels of impulsivity traits as measured by the Barratt Impulsiveness Scale (70.0±10.6 vs. 64.8±11 vs. 60.9±9.3) and more severe frontal dysfunctions (Frontal Assessment Battery, FAB: 12.4±4.9 vs. 15.5±1.6 vs. 14.4±3). A model for PG (incorporating anhedonia, impulsivity levels and frontal impairment) is discussed in the context of the pathophysiology of addictive behaviors. The impairment of hedonic capacity, possibly resulting from an underlying neuropsychological dysfunction, might facilitate loss of control over reward-related behavior, thus favoring the shift towards predominantly habit-based compulsive behaviors.

The DSM-5 has modified the diagnostic criteria for gambling disorder, compared to the fourth edition of the manual; new diagnostic instruments are therefore needed. This study evaluated the psychometric characteristics of the Gambling Disorder Screening Questionnaire (GDSQ), a self-report questionnaire based on the DSM-IV and DSM-5 criteria for Gambling Disorder, measuring its validity, internal consistency, and submitting the questionnaire to a principal components analysis.71 patients from a gambling disorder outpatient clinic and 70 controls were evaluated with the GDSQ, the South Oaks Gambling Screen (SOGS), and a psychiatric interview.The test showed a good sensibility, specificity, internal consistency, concurrent validity with the SOGS. The exclusion of the “illegal acts” item, and the lowering of the cut-off score to four positive items, as suggested by the DSM-5 criteria, improved the test sensibility and internal consistency.The GDSQ can be considered a useful screening test for Gambling Disorder. Furthermore, this study confirms the improved diagnostic accuracy of the criteria listed in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, compared to the previous edition.

Objective We aimed at evaluating the association between appetite and symptoms of depression and anxiety, cognitive dysfunction, fatigue, and comorbidities in patients on hemodialysis (HD). Design A cross-sectional study was conducted. Setting The study was conducted in an outpatient HD service of a tertiary level academic hospital. Patients A total of 90 patients on HD were evaluated for appetite (during the past week, how would you rate your appetite?), symptoms of depression (Beck Depression Inventory [BDI]) and anxiety (Hamilton Anxiety Rating Scale [HARS]), cognitive dysfunction (Mini Mental State Examination [MMSE]), and comorbidities (Charlson Comorbidity Index). Main Outcome Measure Relationship between appetite and symptoms of depression and/or anxiety, cognitive dysfunction, and comorbidities was assessed. Results In 43 patients, the appetite was very good/good (group 1), in 22, it was fair (group 2), and in 25, it was poor/very poor (group 3). Mean and median BDI were significantly higher in group 3 as well as the percentage of patients with BDI ≥16. Mean and median HARS and the percentage of patients with HARS >13 were significantly higher in group 3. MMSE was significantly lower in group 3 as well as the percentage of patients with MMSE ≤23. Multiple linear regression analysis showed a dependence of appetite by age and BDI ( P = .007 and P = .002, respectively). Conclusions Anorexia is associated with older age and symptoms of depression in patients on HD.

Chronic cocaine and heroin users display a variety of central nervous system (CNS) dysfunctions including impaired attention, learning, memory, reaction time, cognitive flexibility, impulse control and selective processing. These findings suggest that these drugs may alter normal brain functions and possibly cause neurotoxicity. Neurotrophins are a class of proteins that serve as survival factors for CNS neurons. In particular, nerve growth factor (NGF) plays an important role in the survival and function of cholinergic neurons while brain-derived neurotrophic factor (BDNF) is involved in synaptic plasticity and in the maintenance of midbrain dopaminergic and cholinergic neurons. In the present study, we measured by enzyme-linked immunosorbent assay (ELISA) the NGF and BDNF levels in serum of three groups of subjects: heroin-dependent patients, cocaine-dependent patients and healthy volunteers. Our goal was to identify possible change in serum neurotrophins in heroin and cocaine users. BDNF was decreased in heroin users whereas NGF was decreased in both heroin and cocaine users. These findings indicate that NGF and BDNF may play a role in the neurotoxicity and addiction induced by these drugs. In view of the neurotrophin hypothesis of schizophrenia the data also suggest that reduced level of neurotrophins may increase the risk of developing psychosis in drug users.

Although the pathophysiology of gambling is unknown, an involvement of midbrain dopaminergic pathway has been hypothesized. In this study, the association between brain-derived neurotrophic factor (BDNF) and pathological gambling was investigated. We measured BDNF serum levels in (1) video players (n = 10); (2) card players (n = 9); (3) mixed players (n = 21; both video and card players) and (4) age-matched controls (n = 18). Mixed players had increased BDNF serum levels as compared to controls and higher South Oaks Gambling Screen score as compared to card or video players. Thus, the data demonstrate that patients affected by severe pathological gambling show enhanced BDNF serum levels.

Bipolar disorders and addictions constitute reciprocal risk factors and are best considered under a unitary perspective. The concepts of allostasis and allostatic load may contribute to the understanding of the complex relationships between bipolar disorder and addictive behaviors. Allostasis entails the safeguarding of reward function stability by recruitment of changes in the reward and stress system neurocircuitry and it may help to elucidate neurobiological underpinnings of vulnerability to addiction in bipolar patients. Conceptualizing bipolar disorder as an illness involving the cumulative build-up of allostatic states, we hypothesize a progressive dysregulation of reward circuits clinically expressed as negative affective states (i.e. anhedonia). Such negative affective states may render bipolar disorder patients more vulnerable to drug addiction, fostering a very rapid transition from occasional drug use to addiction, through mechanisms of negative reinforcement. The resulting addictive behavior-related allostatic loads, in turn, may contribute to illness progression. This framework could have a heuristic value to enhance research on pathophysiology and treatment of bipolar disorder and addiction comorbidity.

Pathological gambling or gambling disorder has been defined by the DSM-5 as a behavioral addiction. To date, its pathophysiology is not completely understood and there is no FDA-approved treatment for gambling disorders. Glutamate is the principal excitatory neurotransmitter in the nervous system and it has been recently involved in the pathophysiology of addictive behaviors. In this paper, we review the current literature on a class of drugs that act as modulating glutamate system in PG. A total of 19 studies have been included, according to inclusion and exclusion criteria. Clinical trial and case series using glutamatergic drugs (N-acetylcysteine, memantine, amantadine, topiramate, acamprosate, baclofen, gabapentin, pregabalin, and modafinil) will be presented to elucidate the effectiveness on gambling behaviors and on the related clinical dimensions (craving, withdrawal, and cognitive symptoms) in PG patients. The results have been discussed to gain more insight in the pathophysiology and treatment of PG. In conclusion, manipulation of glutamatergic neurotransmission appears to be promising in developing improved therapeutic agents for the treatment of gambling disorders. Further studies are required. Finally, we propose future directions and challenges in this research area.

Studies performed in animals and humans have suggested a functional interaction between opioid and cholinergic systems in the control of growth hormone (GH) secretion. Moreover, the sex-dependent modulation of GH secretion in humans is well established. To investigate the role of sex and food intake in the regulation of the reciprocal influences of opioids and acetylcholine in the modulation of GH secretion, we studied the GH response to pyridostigmine (PYR) alone and during a naloxone (NAL) infusion in a group of normal men and women before a meal (at 1:00 PM) and postprandially. In women, the response of GH to PYR alone before the meal was significantly lower than in the men (area under the curve [AUC], mean +/- SEM, 320.18 +/- 87.16 v 1,031.06 +/- 333.21 micrograms/L/90 min, P < .01). Before the meal, NAL completely abolished the response of GH to PYR in men (AUC, 1,031.06 +/- 333.21 v 16.50 +/- 7.50 micrograms/L/90 min, P < .01), whereas infusion of NAL did not significantly modify the GH response to PYR in women. Consumption of the meal significantly decreased PYR-induced GH release in both women (AUC, 21.75 +/- 12.75 v 320.18 +/- 87.16 micrograms/L/90 min, P < .05) and men (AUC, 45.75 +/- 18.75 v 1,031.06 +/- 333.21 micrograms/L/90 min, P < .01). Conversely, food intake did not change the effects of NAL infusion on the GH response to PYR either in women or in men. We conclude that the sex-dependent opioid modulation of PYR-induced GH secretion is observed before a meal but not in the postprandial state. Food intake may be hypothesized to influence the cholinergic regulation of GH secretion and the sex-dependent opioid modulation of central cholinergic tone.

Previous studies have shown that food ingestion is not capable of inhibiting the GHRH-induced GH release in anorexia nervosa, at variance with what is observed in normal subjects. Moreover, a cholinergic alteration has been hypothesized in this disorder. In a group of 24 anorectic patients in a stabilized phase of the illness, we tested, before and after a standard meal, the GH response to GHRH alone and after pre-treatment with pyridostigmine, an inhibitor of acetylcholinesterase, and, on a different day, with oxiracetam, which stimulates the central cholinergic neurones. The GH response to GHRH was significantly increased by both drugs in a fasting state. The postprandial response was not significantly modified by pyridostigmine nor by oxiracetam. Neither of these compounds was able to enhance the postprandial GH ‘paradoxical’ response to GHRH in anorectic patients. The lack of effect of both drugs postprandially also suggests a suppression of somatostatinergic activity.

IntroductionPathological gambling (PG) is currently included among Addictive Disorders (DSM-5). However, its phenomenology resembles features of Obsessive Compulsive Disorder. Several models of addiction conceptualize a progression from impulsivity to compulsivity transitioning from initial positive reinforcement motivations to later negative reinforcement and less pleasurable and automaticity mechanisms.Clinical presentationA 34-year-old male, since diagnosed with PG in 2013 and prescribed a group rehabilitation therapy, presented in 2015 complaining of intrusive thoughts and depression symptoms. During the psychiatric examination emerged: low mental concentration; dysphoria; hyporexia; irritability; insomnia; persistent ideas and excessive preoccupations to be betrayed by his girlfriend; and behaviours of hyper control on her life. He has been evaluated using MMPI-2 (obsessivity Tscore 70, depression Tscore 67) and BIS-11 (high score of non-planning impulsiveness).TreatmentIt appeared there was a shift from ego-syntonic novelty driven/impulsive behaviours focused primarily on gambling to ego-dystonic habit driven/compulsive behaviours focused on her girlfriend. He started an individual psychodynamic psychotherapy centred on dysfunctional beliefs and behavioural strategies for treating the compulsive features. As thought content was the most relevant aspect, he was prescribed olanzapine, not a SSRI (normally indicated for OCD), up to 10 mg/die. After a month obsessions and compulsions reduced, and he seemed to reach a good level of personal functioning, despite a rigid anankastic personality trait.ConclusionsAs the management of compulsive behaviours is complex, physician should better assess and recognize psychological personality aspect, collecting patients’ complete history, also testing them psychometrically, and paying more attention to an eventual treatment (both psychological and pharmacological).Disclosure of interestThe authors have not supplied their declaration of competing interest.

Previously, we have shown that in the opposite extremes of nutritional status, obesity and anorexia nervosa (AN), growth hormone (GH) response to growth hormone-releasing hormone (GH-RH) is not inhibited by the ingestion of a normal 800-cal meal consumed at lunch time (1 pm), which is at variance with results in normal subjects. However, in obese patients the postprandial increase in GH response to GH-RH is inhibited by an infusion of naloxone (NAL). In this study we have tested anorectic patients, performing the following tests at 1 pm: GH-RH test (50 μg IV) or, in a different day session, NAL (1.6 mg/h, starting 30 minutes before GH-RH) + GH-RH test (50 μg IV). The tests were performed in the following three different experimental conditions: (1) short-term fasting studies (lasting from breakfast), (2) long-term fasting studies (from midnight of the day before) and (3) postprandial studies (after a standard meal consumed 1 hour before the test). In AN, the GH response to GH-RH was not influenced by NAL infusion at 1 pm, in both short-and long-term fasting studies (short-term fasting: peak values after GH-RH alone, 26.5 ± 6.5 ng/mL, duirng NAL, 28.0 ± 3.3 ng/mL; long-term fasting: peak values after GH-RH alone, 32.2 ± 6.8 ng/mL, during NAL, 30.6 ± 4.0 ng/mL). A partial NAL-inhibitory effect was instead observed in postprandial studies, as evidenced by the calculation of areas under the curve ([AUCs] 1,662.1 ± 90.0 after GH-RH alone v 1,090.5 ± 245.4 ng/mL/h during NAL). These findings indicate that NAL exerts differential effects in AN before and after a meal. Comparison to the results previously obtained in normal and obese subjects seems to suggest a differential opioid modulation of GH response to GH-RH in AN patients versus normal subjects or patients with obesity.

Little is known about the course of the symptoms of depression/anxiety and the factors predictive of such courses in hemodialysis (HD) patients. This study aimed at evaluating the possible changes of Beck Depression Inventory (BDI) and Hamilton Anxiety Rating Scale (HARS) over time, and factors associated with such changes in HD patients.We screened 110 patients for study participation. Of these, 30 were excluded because of dialytic vintage6 months, alcohol/substance abuse, inability to answer to the questionnaires, diagnosis of psychotic or neurological disorders or recent stressful life events. Eighty patients were included in the study and BDI, HARS, Charlson Comorbidity Index, SF-36 Vitality Subscale, Mini-Mental State Examination (MMSE), routine laboratory parameters, C-reactive protein (CRP) and interleukin-6 were measured at baseline. The 18-month course of BDI and HARS was measured in patients with baseline BDI ≤14.At baseline, 42 patients had BDI14 and 38 patients ≤14. In patients with BDI ≤14, the BDI decreased/remained stable in 19 and increased in 19. Patients with increased BDI had lower baseline MMSE (22.6 ± 2.6 vs. 25.9 ± 2.7, p=0.004) and higher baseline serum CRP (6.07 ± 4.2 vs. 1.64 ± 1.59, p=0.003). At multivariate analysis the relationship between BDI changes and MMSE and serum CRP was statistically significant. In 25 patients, the HARS decreased/remained stable, while in 13 it increased. Characteristics of the 2 groups of patients did not differ significantly.In a meaningful proportion of HD patients, symptoms of depression worsen over time, and CRP and MMSE are independent predictors of such change.

Our study aims to assess the prevalence of behavioural addictions in an adolescent population, evaluating the effects of gender and age, and to assess the correlations among different behavioural addictions. 2853 high school students were assessed in order to evaluate the prevalence of behavioural addictions such as Pathological Gambling (PG), Compulsive Buying (CB), Exercise Addiction (EA), Internet Addiction (IA), and Work Addiction (WA), in a population of Italian adolescents. The South Oaks Gambling Screen-Revised Adolescent (SOGS-RA), the Compulsive Buying Scale (CBS), the Exercise Addiction Inventory (EAI), the Internet Addiction Test (IAT), and the Work Addiction Risk Test (WART), were compiled anonymously by the students. Overall prevalence was 7.0% for PG, 11.3% for CB, 1.2% for IA, 7.6% for WA, 8.5% for EA. PG and EA were more common among boys, while gender had no effect on the other conditions. CB was more common among younger (

In recent years, mobile phone use has become increasingly common among Italian youth, while a growing scientific literature has been identifying the occurrence of a problematic mobile phone use which seems to share some features of other conditions often referred to as behavioural addictions. The study aimed to assess the prevalence of problematic mobile phone use in a population of Italian adolescents and its association with other behavioural addictions. The Mobile Addiction Test (MAT) was administered to 2,790 high school students from Barletta, an Italian town, together with the South Oaks Gambling Screen-Revised for Adolescents (SOGS-RA), the Compulsive Buying Scale (CBS), the Internet Addiction Test (IAT), the Exercise Addiction Inventory (EAI), the Work Addiction Risk Test (WART). MAT scores fitted a Gaussian distribution model. Scores ≥ 17 was found as a cut-off value over which identifying problematic mobile phone users. Overall prevalence of problematic mobile phone use was 6.3%; this condition was associated with other behavioural addictions like compulsive buying. Problematic mobile phone use in adolescence should become a public health issue, and it could be a cause of health problems and social costs.

Gli Autori prendono in esame il caso di M.A., una ragazza anoressica di 18 anni, che, ospedalizzata, rifiuta di sottoporsi alle terapie e di alimentarsi fin quando, durante un episodio di perdita di coscienza, i medici decidono di iniziare - oltre le cure del caso - anche l'alimentazione enterale con il sondino naso-gastrico. Gli interrogativi etici, deontologici e giuridici sollevati da questo caso sono molteplici e rilevanti nella prassi medica: a fronte di un rischio prevedibile per la propria vita, la paziente ha il diritto a non accettare le cure? Quale rispetto è dovuto alla volontà di una paziente affetta da questa malattia? I medici curanti possono lecitamente prendere la decisione di sottoporre la paziente ad alimentazione forzata pur in presenza di un esplicito rifiuto? Le risposte scaturiscono dalla valutazione etica e giuridica del conflitto tra diritto della paziente di decidere sulla propria vita/salute e diritto/dovere del medico di salvaguardare la vita fisica della paziente.

The alpha-2-adrenoceptor agonist clonidine is able to stimulate GHRH secretion directly or via beta-endorphin and, therefore, induces a GH release in normal subjects. This effect has been shown to be blunted in alcoholism during early abstinence, due to central alterations of adrenergic mechanisms. To evaluate pituitary responsiveness to direct stimulation with GHRH, we have studied the GH and PRL response to GHRH in 10 alcoholics during early abstinence. Our data indicate that the pituitary response to GHRH is intact in abstinent alcoholics, except in obese patients, who displayed a blunted GH response. GHRH did not increase PRL. The dissociation between clonidine and GHRH in GH stimulation could reveal a different neuroendocrine mechanism, in comparison with other psychiatric disorders (anorexia nervosa), in which such a dissociation is accompanied by a PRL response to GHRH.

Oxcarbazepine (OXC) is a keto-congener of carbamazepine, which has fewer side effects and drug interactions. However, the efficacy of OXC in treating bipolar disorder is not as well established as that of carbamazepine. This article is a systematic literature review of all studies regarding OXC and bipolar disorders, with particular attention to papers published in the last 6 years. Using the terms 'oxcarbazepine and bipolar disorder', 'oxcarbazepine and mania' or 'oxcarbazepine and bipolar depression', a computer-aided search of MEDLINE for the years 2000-2006 has been conducted. Since its introduction as an antiepileptic drug in early 2000, clinical research regarding the potential role of OXC in the treatment of bipolar disorder remains limited. There is a lack of double-blind, placebo-controlled studies. Studies recently published have small samples of patients, with insufficient follow-up periods and other methodological weaknesses. The efficacy of OXC in bipolar disorder has not been widely studied. Some authors recommend using OXC as monotherapy or as add-on therapy in refractory mania, although results are not conclusive. It is unknown whether OXC has efficacy in the maintenance treatment of bipolar disorder. OXC can be particularly useful as an add-on treatment in bipolar disorder patients for whom previous treatments have failed, or in patients who have difficulty tolerating adequate dosages of standard approved treatments.

Background and Aims Internet Gambling has become one of the most popular and lucrative internet business. The recent improvements in technology have changed betting habits with online poker, casinos, sport betting, bingo and lotteries. Liberalization of the Italian online gambling market gradually started in 2006, but only in 2010 foreign gambling operators have been able to launch online real money games. Our aim is to study the impulsivity and personality traits of an Italian sample of Pathological Gamblers (PG), showing the peculiarities of Online Gambling (OG). Methods 69 patients affected by PG, who accessed to our clinical center, were asked to fill the following questionnaires: - Temperament and Character Inventory-Revised (TCI-R) - Europ-ASI (Addiction Severity Index) - Barratt Impulsiveness Scale (BIS-11) Results we found significant statistical correlations between OG and: younger age (p Conclusions internet gamblers’ young age could explain the correlations between OG and higher scores in NS1, HA2 and ST3, and consequently risky behaviours and less spiritual believes/acceptance. Higher scores in Persistence indicate perseverance in spite of fatigue or frustration. Cloninger's research found that Persistence, like the other temperament traits, is highly heritable.

Coenzyme Q10 in seminal fluid shows a direct correlation with seminal parameters except in patients with varicocele. To evaluate whether surgical treatment of varicocele could revert CoQ10 abnormalities, we have studied CoQ10 distribution in thirty-three VAR patients, before and 6-8 months after varicocelectomy, twenty patients with idiopathic oligozoospermia, eleven with isolated asthenozoospermia and sixteen normal fertile men. CoQ10 was assayed in total seminal fluid, plasma or cell pellet by HPLC. A significantly higher CoQ10 proportion in seminal plasma in VAR vs. controls (mean +/- SEM: 61.68 +/- 2.41 vs. 41.60 +/- 1.99%, respectively) was present; total CoQ10 correlated with sperm motility in controls, but not in VAR; an inverse correlation between cellular CoQ10 and motility was present in VAR, but not in controls. Postoperatively, a partial reversion was observed, since the plasma-to-total CoQ10 ratio decreased, but the correlation between total CoQ10 and motility was not restored. On the contrary, the peculiar correlation between cellular CoQ10 and motility was no more detectable in postoperative VAR patients. A partial postoperative reversal of abnormalities in CoQ10 distribution and correlation with seminal parameters was therefore present. As seminal plasma CoQ10 reflects an interchange between intracellular and extracellular compartments, its different distribution could cause a greater sensitivity to peroxidative damage and a reduced utilization for energetic purpose.

Previously we demonstrated that coenzyme Q10 (CoQ10) is present in human seminal fluid and shows a direct correlation with seminal parameters except in patients with varicocele (VAR). We have now evaluated CoQ10 distribution in VAR, versus control subjects, in order to discover metabolic abnormalities within this condition. We studied 32 patients with VAR (11 with oligoasthenozoospermia, 13 with asthenozoospermia, and 8 with normozoospermia), and, as controls, the following groups of subjects, matched with VAR patients according to seminal parameters: 16 patients with idiopathic oligozoospermia, 11 patients with isolated asthenozoospermia, and 14 normal fertile men. CoQ10 was assayed in total seminal fluid, plasma, or cell pellet by high-performance liquid chromatography (HPLC). We found a significantly higher proportion of CoQ10 in seminal plasma in VAR; cellular CoQ10 showed an inverse correlation with sperm concentration and motility in VAR, at variance with controls. As seminal plasma ubiquinone reflects an interchange between intracellular and extracellular compartments, the different distribution in VAR patients could represent a greater sensitivity to peroxidative damage and could suggest reduced utilization for energy, which in turn could cause a defective motility even in patients with a normal cell count. These data suggest a pathophysiological role of CoQ10 in seminal plasma and a possible molecular defect in VAR.

Trazodone is a non-tricyclic antidepressant drug with specific antagonistic activities at 5-HT(2) and alpha-1 adrenoceptors. We test the efficacy of trazodone (T) compared with clonidine (C) in rapid opiate detoxification (ROD) from methadone after reduction to a daily maintenance dose

The need for a specific therapeutic-rehabilitative group for cocaine addicted patients rises up both from the progressive increase of cocaine use in the general population and from peculiar personality traits and associated psychopathology of these clients. Moreover, it is difficult to mantain a compliance to therapy, because there are no specific anticraving or antidothic drugs for cocaine addiction.Therefore our equipe developed a short integrated treatment (ten weeks), of “group concelling” and “psychodinamic group therapy” in association. The group is open and composed by a maximum of eight participants.The novelties of this model are: (1) hospital setting, (2) a short duration and (3) synergy between two different approaches: Minnesota 12 steps model (one sessions weekly, held by a councellor on addiction), and a psychodinamic group therapy (one session weekly).Main success is the retention of patinets in therapy for a long time. In twenty months (March 2005- October 2006), fourty cocaine-addicted patients started this program: only 30% of them dropped out, while 70% of patients completed the treatment. 64% of the latter where completely abstinent, while 36% relapsed during the therapy. All of them are still continuing some therapy at the moment: 46% individual psychotherapy, 25% individual psychotherapy and pharmacological therapy, 14% narcotics anonymous attendance, 11% N.A. groups and pharmacological therapy, 4% is in a T. C.

In a previous paper it was demonstrated that Coenzyme Q10, a lipidic molecule with important antioxidant properties, is present at remarkable levels in human seminal fluid, and shows a direct correlation with seminal parameters (sperm count and motility). In patients with varicocele, on the contrary, correlation with sperm motility was lacking and a higher proportion of Coenzyme Q10 was found in seminal plasma. In the present study, the levels of Coenzyme Q10 in the cell pellet of spermatozoa, obtained after centrifugation of semen, were evaluated. In nonvaricocele subjects it was observed that a higher concentration of Coenzyme Q10 (expressed as ng of the molecule per million of cells) was present in the spermatozoa of oligospermic and asthenospermic patients (sperm count < 20 x 10(6) spermatozoa ml-1, sperm motility < 40%). This relationship was not observed in varicocele subjects, who also showed slightly lower intracellular absolute values of the conenzyme. Since Coenzyme Q10 is an antioxidant molecule involved in the defence of the cell from free radical damage, higher intracellular concentrations may represent a mechanism of protection of the spermatozoa. In varicocele patients, this mechanism could be deficient, leading to higher sensitivity to oxidative damage.

Aims There is substantial evidence indicating that pharmacological treatments targeting glutamatergic transmission are of potential utility in the treatment of drug addiction. The aim of this study was to evaluate the long-term outcome of glutamatergic treatments in patients with pathological gambling. Methods Fifteen patients fulfilling criteria for pathological gambling and receiving drugs with effects on glutamatergic transmission (amantadine, N-acetylcysteine, gabapentin, pregabalin and topiramate) were enrolled. Gambling craving (Gambling Symptom Assessment Scale, G-SAS, and visual analogue scale, VAS) and relapse (Gambling Timeline Follow Back, G-TLFB) rating scales were administered before and after treatment (1, 3, 6 months follow-up). Results Gambling craving and behavior were significantly reduced (p Discussion Our results are discussed in the context of the glutamatergic hypothesis of addiction. Our data seem to confirm the utility of targeting the glutamatergic system for the treatment of PG, in particular by acting on craving and increasing treatment retention. In particular, glutamatergic medications may offer some advantages in preventing relapse.

Introduction Frequent and increasing relations among psychiatric and substance dependence disorders, have made, to date, more complex the treatment of this dependence, especially when the patient is facing the difficult task of maintaining abstinence, which requires a work of self-awareness, motivation to change and active modification of dysfunctional lifestyles. Objectives Our study has the aim to detect patients’ changes in personality between the beginning of the rehabilitative therapy and its end, trying to get information on aspects of addiction on which the treatment affects the most. Methods Our sample was formed by 153 patients, recruited at the Department of Psychiatry of Gemelli General Hospital, who were subjected to an integrated approach of treatment, both pharmacological and rehabilitative group-therapy, according to Minnesota rehabilitation model, that considers addiction as a bio-psycho-social problem. Patients, after a first psychiatric evaluation, were asked to fill out two psychometric tests, the SymptomCheckList-90 R and the Structural Clinical Interview for DSM-IV, in two times, at the first meeting and at the last one, after 20 meetings of group therapy. Results At the end of the group therapy 39 patients dropped-out, 114 patients had a significant improvement in depressive symptoms (DEP item), greater responsibility perseverance and attention in their activities and habitual contexts (GSI, DIS, W/S items), as well as better management of compulsion and impulsivity (OC item) and a lower sense of inferiority, inadequacy and discomfort in interpersonal relationships (PAR, ANX, IS, SOC. A., PSY. A. items).

Introduction Different questionnaires were formulated in order to assess the severity of gambling. The most used questionnaire is the South Oaks Gambling Screen (SOGS), based on DSM-III criteria for gambling, even though it has poor specificity, because overestimates the prevalence of the disorder when used in general population. Objectives Try to overcome SOGS limits using a questionnaire based on DSM-IV criteria for gambling. Aims Validate the questionnaire based on DSM-IV criteria, using as gold standard the clinical interview developed through the SOGS. Methods The sample used is formed by 71 subjects, 58 men (81.7%) and 13 women (18.3%), recruited from the Psychiatric Department of Gemelli General Hospital in Rome, who were asked to fill out both questionnaires. Results The sensitivity of our questionnaire was 93% (compared to 100% in the SOGS); the specificity was 100% (97.1% in the SOGS). False negatives were 7%, while they were absent in the SOGS ; false positives were absent in the DSM-IV questionnaire, while they were 2.9% in the SOGS. We also determined the prevalence of each item of DSM-IV questionnaire in all gamblers identified (66 subjects): the most relevant item was “chasing one's losses”(item6), instead the least one was “committing illegal acts such as forgery, fraud, theft, or embezzlement to finance gambling”(item8). Conclusions Our data confirm the greater specificity of the questionnaire of DSM-IV criteria for gambling compared to the SOGS. We suggest its use for the identification of gamblers in a sample formed by general population.

A great number of metabolic and hormonal derangements have been described in traumatized patients. Plasma concentrations of many substrates, enzymes, and metabolites rise and/or fall, and indices of organ and tissue function change without unequivocal overall patterns. Endocrine variations can mediate a lot of these metabolic pathway dysfunctions; in general two different secretory patterns can be seen in anterior pituitary hormones: an increase of adrenocorticotropic hormone (ACTH), prolactin (PRL), and growth hormone (GH) and a decrease of other hormones [thyroid stimulating hormone (TSH), luteinizing hormone (LH), follicle stimulating hormone (FSH)]. Neurohypophysial hormones can be involved depending on the kind of trauma. Catecholamines, insulin, and glucagon levels also change, and are of fundamental importance in the regulation of intermediate metabolism in such patients.

Introduction Pathological gambling (PG) disorder occurs when a person gambles repetitively despite severe negative effects on important aspects of life. PG tends to be a heterogonous disorder in which patients differ with respect to type and intensity of gambling behavior, psychiatric comorbidity, family history, age at onset and gender. Gamblers may accordingly be classified into three subtypes: the “impulsive”, “obsessive-compulsive” and “addicted” subtypes. Aims to characterize a sample of Italian PG pathological gamblers and assess the prevalence of the various gambling subtypes in this population. Methods 52 outpatients (44 men, 9 women), diagnosed with PG according to DSM IV-TR and SOGS criteria, were administered the Dannon Ainhold Gambling Scale (DAGS), which assesses the presence of the disorder and is useful for patient subtyping. Results 37 gamblers enrolled in our study played one specific kind of game, while 15 played multiple games. 30 patients played slot machines, 18 sport betting, 11 casino and card games, 14 bingo and scratch cards. According to DAGS, 5 (9,6%) patients belonged to the “addicted” subtype, 4 (7,7%) to the “obsessive-compulsive” subtype and 9 (17,3%) to the “impulsive” subtype. 15 (28,8%) gamblers were classified as “addicted-impulsive” subtype, 10 (19,2%) as “addicted-obsessive-impulsive” subtype, while 9 (17,3%) did not belong to any specific subtype though they displayed a tendency for one of the subtypes. Conclusion DAGS allows to identify three major subtypes of gamblers and also considers possible combinations between the different subtypes. An evaluation of these aspects could be useful in treatment options based on patient subtype.

Introduction Pathological gambling refers to the uncontrollable impulse to gamble, irrespective of the interference the behaviour has on the individual's life. It often results in disrupted relationships, financial problems, criminal behaviour and yet the individual is unable to refrain. Aims Our aim is to evaluate the relationship among impulsivity traits, personality assessment and psychiatric comorbidity in a sample of pathological gamblers. Methods 78 pathological gamblers were evaluated with the following instruments: MINI to evaluate psychiatric comorbidity; TCI to evaluate personality traits, and BIS-11 to evaluate impulsivity. Pathological gambling was assessed with DSM-IV-TR criteria. Results In our sample we found an average score of BIS-11 (66,9) slightly higher than the score of the general population (63,8). The scores of TCI, compared with the mean scores of the general population, differ significantly with regard to NS, RD, C, ST. As to MINI, it reveals a significant prevalence of Major Depressive Episode, Dysthymia, GAD, and risk of suicide. We identified two groups at high and low impulsivity and we conducted an analysis in relation to personality traits measured by TCI and incidence of psychiatric comorbidity measured by the MINI. The group with high impulsivity was associated with significantly higher scores of NS and HA, and lower RD and SD. Also in this group there was a higher incidence of Major Depressive Episode and GAD. Conclusions The analysis allows to identify the impulsive trait as a discriminating factor of two different types of players in relation to personality characteristics and psychiatric comorbidity.

IntroductionPsychiatrists play an important role as members of the bariatric surgery team. A preoperative psychiatric evaluation is considered as part of a mandatory workup before approving surgery.AimsThis evaluation focuses on the identification of any pre-existing psychiatric disorders among candidates for TOGa[1], a new experimental technique of bariatric surgery, and their correlations with post surgical weight loss.Method45 obese patients underwent a psychiatric interview and several psycho diagnostic questionnaires (SCL-90; HAM-D; HAM-A; EDI; TAS).A follow-up was set each 3 months.ResultsWe found that 34.1% of surgery candidates had a current diagnosis of depression; the majority showed anxiety symptoms. We also documented dissatisfaction about body shape, desire of slimness, fear of maturity, perfectionism, bulimia and binge eating disorder. Other frequent psychiatric symptoms were somatization, sensitivity, obsession and compulsion. After 3 months from surgery we found that the best weight loss was associated to low score in HAM-A, high score in hanger-hostility item (SCL-90) and low score in sensitiveness item (SCL-90).ConclusionThe diagnosis of a psychiatric pathology during the pre-surgical evaluation can be considered a predictive negative factor for the outcome of the surgery. The predictive positive factors are firstly the nonexistence of psychiatric symptoms, secondly the high score in sensitiveness-insight item (SCL-90) and the high score in the ability to express feelings.

Thyrotropin releasing hormone (TRH) administration is known to induce a greater TSH response in normal subjects than in obese subjects. In obesity even GH and PRL response to various stimuli are blunted, presumably because of an augmented somatostatinergic tone in obese subjects. Further studies have shown that pyridostigmine (Pyr), an acetylcholinesterase inhibitor, is capable of augmenting GH in obesity by means of somatostatin inhibition. In order to evaluate the possible interference of an increased somatostatinergic tone on TSH secretion, we studied the TSH response to a TRH bolus in 5 obese children with or without a pyr pretreatment. Similarly, we tested a group of 10 obese adult subjects, with TRH alone or TRH plus pyr administration, 30 min or 60 min before TRH. All subjects had a body weight of 30-50% greater than I.B.W. Our data show that a pretreatment with pyr, 60 min before TRH administration, significantly augments the TSH response in adult obese subjects but not in children; the modality of pyr administration seems to be crucial to evidenciate such an alteration since the pyr pretreatment is not effective when administered 30 min before TRH. The absence of this pyr effect in obese children induces to hypothesize that somatostatinergic tone is differentially modulated in children vs adult obese subjects.

Previous studies have indicated different abnormalities of PRL secretion in patients with primary empty sella (PES). Since it is known that endogenous opiates and dopamine interact in modulating PRL secretion, we have studied the effect of an opiate receptor blockade (with Naloxone, NAL, 1.6 mg/h as a continuous infusion) on anterior pituitary hormones and on PRL responsiveness to metoclopramide (MCP), in 10 premenopausal normoprolactinemic patients with PES, studied in follicular phase, in order to investigate neurotransmitter abnormalities present in such a syndrome. NAL failed to significantly affect LH and FSH basal levels; on the contrary, slight but significant increases in PRL and GH secretion were observed. NAL partially blunted the PRL responsiveness to the dopaminergic blockade, which was very marked when tested after MCP alone. These data confirm that the modulation of anterior pituitary hormone secretion is different in PES patients, when compared with normal subjects. The infusion of NAL induced a "paradoxical" increase in hormones (PRL and GH) which are normally stimulated by endogenous opiates; but, on the other side, it blocked the marked PRL responsiveness to the dopaminergic blockade, which is characteristic of PES syndrome. This phenomenon seems to indicate that the relationships between dopaminergic and opiatergic neurons could be modified by the neuroanatomic alteration which is present in this complex syndrome.

Since November 2005 our Institute has been developing a group therapy program for pathological gamblers, alternating a counselling/rehabilitation and a group psychotherapy session each week. For a better understanding of psychodynamic aspects of our patients we have started to assess them through Rorschach test according to Klopfer signing and with TAS-20 (Toronto Alexithymia Scale, Taylor et al., 1990). Preliminary results regarding ten patients have shown the following features: a discrepancy between high ambition and real intellectual skills; a psychic life condition dominated by immature resources and impulses; an inappropriate self-control which is performed through emotional distance and experiences of deep anguish. These features can be indicative of a difficulty in expression of emotions, according to alexithymia construct. Most of the patients were found to have significantly higher levels of alexithymia at Tas-20. This outcome is in accordance with previous works on the topic.Our preliminary observations suggest to focus group therapy not only on communication contents, but also on the communication style of the patient. These results also suggest that could be important to help patient to recognize and discriminate emotional conditions to prevent relapses due to out of control or repressed emotions.[1].
