    This study is the first to have demonstrated, by means of a highly sensitive test of visual memory, a potential hippocampus neuroprotective effect of lithium in patients with BD. Undoubtedly, other studies are needed to finally recognize lithium as a potential cognitive enhancer. Future studies should include, apart from highly sensitive cognitive tests, specific neurotrophic biomarkers, such as BDNF, NGF, etc. Finally, it will be of outmost importance to evaluate the minimal length of treatment and the optimum serum level in order to combine potential clinical benefit and, particularly for older patients, clinical safety

    Condotte compulsive in paziente con sindrome di Aicardi. agenesia del corpo calloso

    The corpus callosum, which is the largest white matter structure in the brain of all placental mammals, connects the left and right cerebral hemispheres. An alteration in its morphology, hypoconnectivity or hyperconnectivity is a common marker of various neuropsychiatric pathologies. One of these is Aicardi syndrome, which is characterized by a triad of callosal agenesis, infantile spasms and chorioretinal lacunae. Patients affected by Aicardi syndrome frequently display other malformations together with congenital defects of the eyes, ribs and vertebrae. Based on the current clinical knowledge, this syndrome is now recognized as a complex neurodevelopmental disorder that includes neurological and constitutional symptoms. However, literature data have not yet defined the presence of a particular set of symptoms in psychiatric patients with this condition. The present case is the first report in which an on-going compulsive behaviour focused on the insistence to order objects has been observed in Aicardi syndrom

    La legalizzazione della cannabis. Tra irresponsabilitĂ  politica e deresponsabilizzazione degli psichiatri

    In Italy a political parliamentary majority, recognized by all the press as "cross party", is going to approve the law that will legalize the use of cannabis. As diversified in different Countries, it is a phenomenon which affects substantially homogeneous many European nations, as well as several states of the USA and other Countries of the world. The authors, after listing the main harmful effects of cannabis, especially in young people, on cognitive functions and on the onset of several psychotic disorders, express the need for reflection by the mental health experts on a problem of extreme relevance and urgency care

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly citedIntroduction. The use of novel psychoactive substances (NPSs) has rapidly increased as well as their online availability. The aim of this paper is to provide a comprehensive review of the nature and the risks associated with 25C-NBOMe, which has recently appeared in the drug market. Methods. A systematic analysis of the scientific literature and a qualitative assessment of online and media resources (e.g., e-newsgroups, chat-rooms, and e-newsletters) in 10 languages were carried out. Results. 25C-NBOMe is sold online as legal LSD or as research chemical with different designations such as “Boom,” “Pandora,” “Holland film,” or “N-bomb.” It is a partial agonist of 5-HT2A receptors. It is usually ingested orally/sublingually and, less commonly, nasally, through injection, vaginally, rectally, and smoked. Its effects include sublingual numbing, stimulation, “body high,” hallucinations, dissociation, and anxiety. 25C-NBOMe presents high risk of overdoses; acute toxicity and fatalities have been reported. Conclusions. 25C-NBOMe consumption represents an emerging phenomenon with potential harmful effects. Its use is increased by its online availability at low costs. Health and other professionals should be informed about this new trend of substance usePeer reviewedFinal Published versio

    The “Eyeballing” technique : an emerging and alerting trend of alcohol misuse

    Alternative methods of alcohol consumption have recently emerged among adolescents and young adults, including the alcohol “eyeballing”, which consist in the direct pouring of alcoholic substances on the ocular surface epithelium. In a context of drug and behavioural addictions change, “eyeballing” can be seen as one of the latest and potentially highly risky new trends. We aimed to analyze the existing medical literature as well as online material on this emerging trend of alcohol misusePeer reviewedFinal Published versio

    The assisted suicide of Italians in Switzerland and the silence of psychiatry

    Get PDF
    The debate on different forms of request of death has taken on a broad dimension in public opinion over last years, often referring on profoundly differentiated and often opposing positions of principle. Beyond cultural, political or ideal positions, a further critical issue, often underestimated or quite not considered, concerns a person’s ability to express a valid consent to the request of death, according to the same criteria of validity of the informed consent to any medical act. This assumes particular importance in the case of assisted suicide. Assisted suicide represents a phenomenon in sharp growth in Western world. It is legal in many nations, and in Switzerland it is also allowed for foreign citizens, thus increasing the phenomenon of the so-called “tourism of suicide”. In addition to neoplastic and neurological diseases, depression has also been accepted as a disease that makes assisted suicide possible. This imposes profound clinical and ethical considerations, since depression is unanimously recognized as a treatable disease and since in its most serious forms, such as those in which suicidal ideation dominates, it can compromise the patient’s ability to express a valid consent to any medical act, including the assisted suicide. Furthermore, it is often overlooked that any serious and disabling somatic disease, source of intense and chronic suffering, carries the very high risk of the onset of unrecognized depressive conditions, able in turn to negatively influence the ability to express valid consent. Faced with this situation, which has involved a large number of Italian citizens in recent years, the personal and official voice of psychiatry is absolutely lacking, contrasting its silence with the opinions of those who do not want to take into account its potentially fundamental considerations

    Negative symptoms as key features of depression among cannabis users: a preliminary report.

    Get PDF
    OBJECTIVE: Cannabis use is frequent among depressed patients and may lead to the so-called "amotivational syndrome", which combines symptoms of affective flattening and loss of emotional reactivity (i.e. the so-called "negative" symptomatology). The aim of this study was to investigate the negative symptomatology in depressed patients with concomitant cannabis use disorders (CUDs) in comparison with depressed patients without CUDs. PATIENTS AND METHODS: Fifty-one patients with a diagnosis of Major Depressive Disorder (MDD) and concomitant CUD and fifty-one MDD patients were enrolled in the study. The 21-Item Hamilton Depression Rating Scale (HDRS) and the negative symptoms subscales of the Positive and Negative Syndrome Scale (PANSS) were used to assess depressive and negative symptomatology. RESULTS: Patients with cannabis use disorders presented significantly more severe negative symptoms in comparison with patients without cannabis use (15.18 ± 2.25 vs 13.75 ± 2.44; t100 = 3.25 p = 0.002). DISCUSSION: A deeper knowledge of the "negative" psychopathological profile of MDD patients who use cannabis may lead to novel etiopathogenetic models of MDD and to more appropriate treatment approaches

    Demographic variables, clinical aspects, and medicolegal implications in a population of patients with adjustment disorder

    INTRODUCTION: Although adjustment disorder (AD) is considered as residual diagnosis and receives little attention in research, it plays an important role in clinical practice and also assumes an increasingly important role in the field of legal medicine, where the majority of diagnostic frameworks (eg, mobbing) often refer to AD. Our study aimed to look for specific stressor differences among demographic and clinical variables in a naturalistic setting of patients with AD. METHODS: A restrospective statistical analysis of the data of patients diagnosed with AD from November 2009 to September 2012, identified via manual search from the archive of the outpatient setting at the University Unit of Psychiatry "A. Fiorini" Hospital, Terracina (Latina, Italy), was performed. RESULTS: The sample consisted of 93 patients (46 males and 47 females), aged between 26 and 85, with medium-high educational level who were mainly employed. In most cases (54.80%), a diagnosis of AD with mixed anxiety and depressed mood was made. In all, 72% of the sample reported a negative family history for psychiatric disorders. In 22.60%, a previous history of psychopathology, especially mood disorders (76.19%), was reported. The main stressors linked to the development of AD were represented by working problems (32.30%), family problems (23.70%), and/or somatic disease (22.60%) with significant differences with respect to age and sex. Half of the patients were subjected to a single first examination; 24.47% requested a copy of medical records. CONCLUSION: Confirming previous data from previous reports, our results suggest that AD may have a distinct profile in demographic and clinical terms. Increased scientific attention is hoped, particularly focused on addressing a better definition of diagnostic criteria, whose correctness and accuracy are critical, especially in situations with medicolegal implications

    Mistrust and Beliefs in Conspiracy Theories Differently Mediate the Effects of Psychological Factors on Propensity for COVID-19 Vaccine

    Vaccination is considered a key factor in the sanitary resolution of the COVID-19 pandemic. However, vaccine hesitancy can undermine its diffusion with severe consequences on global health. While beliefs in conspiracy theories, mistrust in science and in policymakers, and mistrust in official information channels may also increment vaccine hesitancy, understanding their psychological causes could improve our capacity to respond to the pandemic. Thus, we designed a cross-sectional study with the aim of probing vaccine propensity in the Italian population and explored its relationship with sociodemographic and psychological variables, and with misbeliefs in COVID-19. A battery of questionnaires was administered to a sample of 374 Italian adults during the first national lockdown (April 2020). The materials included an original instrument—Beliefs in COVID-19 Inventory—and questionnaires measuring perceived stress, anxiety, death anxiety, psychological distress, psychoticism, paranoia, anger, and somatization. The exploratory factor analysis (EFA) on Beliefs in COVID-19 suggested the existence of three factors: belief in conspiracy theories, mistrust in medical information, and mistrust in medicine and science. These factors were positively correlated with female sex, age, religious beliefs, psychiatric conditions, and psychological variables, while negatively correlated with education levels. We conducted a mediation analysis by means of a structural equation model, including psychological factors as predictors, beliefs in COVID-19 scales as mediators, and vaccine propensity as an outcome. The model showed that death anxiety had a direct positive effect on the propensity to get vaccinated. It also showed that death anxiety reduced the propensity to get vaccinated through a mediated path in believing in conspiracy theories, whereas paranoia was linked to a reduction in vaccination adherence with the mediation effect of mistrust in medical science. Psychological distress reduced vaccination propensity by increasing both conspiracy beliefs and mistrust. On the other hand, anxiety increased the propensity to get vaccinated through a decrease in both belief in conspiracy theories and mistrust in science. Our results suggest that psychological dimensions are differentially related to belief in conspiracy theories, to mistrust in science, and to the propensity to get vaccinated. Based on this result, we propose an original interpretation of how conspiracy beliefs build on a paranoid and suspicious attitude. We also discuss the possible clinical implications of treatment for such pathological beliefs

    A Reaction-Diffusion Numerical Model to Predict Cardiac Tissues Regeneration Via Stem Cell Therapy

    Myocardial infarction is a leading cause of morbidity and mortality in the industrialized world. Extensive loss of cardiomyocytes, substituted by scarred tissue, is the key pathological mechanism leading to post infarc- tion heart failure [1]. The use of exogenous cells to replace lost cardiomy- ocytes has been demonstrated in animal models and in clinical trials by transplanting mesenchymal stem cells (MSCs) into the infarcted area. To optimize the initial conditions of the stem cell therapy, many experimen- tal studies are focused on determining the number and the localization of stem cells that must be implanted near the necrotic area. In this work we develop a quantitative numerical model able to simulate substrate con- centration profile, stem cells distribution and their proliferation near the ischemic area. The model describes the cell growth, the nutrient transport and its consumption through reaction-diffusion equations. The shrinking of the necrotic area leads in fact to a moving boundary problem. Some preliminary results, obtained in a 3D framework, are shown and discuss
