The Clinical and Radiological Examination of Acute Intimate Partner Violence Injuries: A Retrospective Analysis of an Italian Cohort of Women.

BACKGROUND: Intimate partner violence (IPV) is the most frequent type of violence against women. We compared clinical and radiological IPV characteristics to stranger assault (SA). METHODS: We retrospectively identified 123 women with IPV from court reports and matched them to 124 SA. Clinical and radiological characteristics were evaluated by testing their sensitivity, specificity, positive and negative predictive value for IPV, and the strength of their association with IPV. RESULTS: IPV women referred with more delay to the emergency department (ED), had more ED accesses, and showed more mismatch between reports to the triage and disclosures to the ED physician. They also displayed more head, neck, and face injuries, and new-plus-old fractures. CONCLUSION: The identification of specific features may help ED physicians to suspect IPV.

Are 5-HT3 antagonists effective in obsessive-compulsive disorder? A systematic review of literature.

OBJECTIVE: The purpose of this literature database search-based review was to critically consider and evaluate the findings of literature focusing on efficacy and safety of 5-HT3 antagonists in the treatment of obsessive-compulsive disorder (OCD), so as to test whether preclinical data match clinical therapeutic trials. DESIGN: The PubMed database has been searched for papers on 5-HT3 antagonists and OCD in humans and for animal models of OCD and 5-HT3 receptors. RESULTS: Of the clinically tested 5-HT3 receptor antagonists, ondansetron has been used to treat OCD in five therapeutic studies, whereas granisetron only in one recent trial. Both showed some efficacy in open studies and superiority to placebo in double-blind studies, along with fair safety. No animal OCD model directly implicated 5-HT3 receptors. CONCLUSIONS: Overall, results indicate some utility, but the available literature is too scanty to allow for valid conclusions to be drawn. The mismatch between animal models of obsessive-compulsive disorder and clinical data with 5-HT3 antagonists needs more clinical data to ensure that it is not an artefact.

Symptom correlates of facial emotion recognition impairment in schizophrenia.

BACKGROUND: The ability to facial emotion recognition (FER), a key component of socioemotional competence, is often impaired in schizophrenic disorders. The purpose of the present study was to examine the relationship between emotion recognition performance and symptoms in a group of patients with schizophrenia spectrum disorders. SAMPLING AND METHODS: Seventy-nine patients meeting DSM-IV-TR criteria for schizophrenia, schizophreniform disorder and schizoaffective disorder were assessed by the Positive and Negative Syndrome Scale and a FER task. In schizophrenia patients and healthy control subjects, FER performance was compared. In order to avoid a possible confounding role of cognitive impairment, we carried out partial correlations corrected for an index of global cognition. RESULTS: Patients performed worse than a healthy control group on all negative emotions. Partial correlations showed that cognitive/disorganized symptoms correlated with a worse performance in the FER task, whereas no correlations were found with positive, negative, excitement and depressive symptoms. CONCLUSIONS: Our findings support that in schizophrenia FER impairment is specific for negative emotions and that there is a relationship between this deficit and cognitive/disorganized symptoms, regardless of the general cognitive level.

Neurodevelopment in schizophrenia: the role of the wnt pathways.

OBJECTIVES: To review the role of Wnt pathways in the neurodevelopment of schizophrenia. METHODS: SYSTEMATIC PUBMED SEARCH, USING AS KEYWORDS ALL THE TERMS RELATED TO THE WNT PATHWAYS AND CROSSING THEM WITH EACH OF THE FOLLOWING AREAS: normal neurodevelopment and physiology, neurodevelopmental theory of schizophrenia, schizophrenia, and antipsychotic drug action. RESULTS: Neurodevelopmental, behavioural, genetic, and psychopharmacological data point to the possible involvement of Wnt systems, especially the canonical pathway, in the pathophysiology of schizophrenia and in the mechanism of antipsychotic drug action. The molecules most consistently found to be associated with abnormalities or in antipsychotic drug action are Akt1, glycogen synthase kinase3beta, and beta-catenin. However, the extent to which they contribute to the pathophysiology of schizophrenia or to antipsychotic action remains to be established. CONCLUSIONS: The study of the involvement of Wnt pathway abnormalities in schizophrenia may help in understanding this multifaceted clinical entity; the development of Wnt-related pharmacological targets must await the collection of more data.

Epilepsy and brain injury: a case report of a dramatic neuropsychiatric vicious circle.

PRIMARY OBJECTIVE: Early treatment of epilepsy is warranted to avoid possible severe consequences. This study aimed to assess the value of treatment in a patient who developed epilepsy after major brain surgery. DESIGN: Case description. A 51 years-old man had a history of putative petit mal seizures since adolescence and left frontotemporal lobectomy after a major traffic accident at age 17. He subsequently developed quickly generalizing partial complex seizures, associated with severe behavioural alterations and personality changes; the condition was left untreated. A further seizure-related loss of consciousness led to another traffic accident at age 47. METHODS AND PROCEDURES: The patient was administered 200 mg/day topiramate, 600 mg/day quetiapine, 1000 mg/day valproate, 1200 mg/day gabapentin and 800 mg/day carbamazepine. MAIN OUTCOMES AND RESULTS: The instituted anti-epileptic treatment reduced seizure frequency and severity, but did not affect psychiatric symptomatology, which even worsened. An association between anti-epileptic drugs with mood stabilizing properties and an atypical anti-psychotic dramatically improved psychiatric symptoms, but did not prevent the patient from needing long-term healthcare. CONCLUSIONS: Long-term untreated epilepsy may expose to accident proneness and further psychiatric deterioration. Early diagnosis and treatment of epilepsy may help in avoiding a potentially lethal vicious circle.

Prevention of relapse with maintenance electroconvulsive therapy in elderly patients with major depressive episode.

OBJECTIVES: To evaluate the effectiveness and safety of maintenance electroconvulsive therapy (mECT) in elderly patients with treatment-resistant Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition major depressive episode. METHODS: Seven elderly patients with treatment-resistant major depressive episode were treated with a complete ECT cycle. Thereafter, they received one monthly ECT session as maintenance for 1 year. Response to treatment was defined as at least a 50% drop from baseline on the Hamilton Depression Rating Scale (HamD) and remission as not meeting criteria for major depression, a HamD score of 7 or less, and Clinical Global Impressions-Severity of Illness score of 1. We compared their response with the response of 7 elderly patients with treatment-resistant major depression who were treated with a full cycle of ECT but did not receive mECT (non-mECT). We compared the 2 groups for the number of relapses or recurrences of major depressive episodes after remission was achieved; a relapse or a recurrence occurred when HamD scores were 14 or higher, or when Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision major depressive episode criteria were met, or when Clinical Global Impressions-Severity of Illness score was 3 or higher and increased by at least 2 points from response/remission. RESULTS: The mECT group (4 women and 3 men; mean age, 73 years) had significantly less mean relapses/recurrences (0 vs 1.57) and hospitalizations (0 vs 1) and received less drug treatment than the nonMECT group (similar for age and sex composition) during the 12-month follow-up period. All patients with mECT improved during treatment and did not relapse. CONCLUSIONS: Maintenance ECT protected elderly patients from recurrent depressive episodes from relapsing/recurring more than standard ECT.

Electroconvulsive therapy in a man with comorbid severe obesity, binge eating disorder, and bipolar disorder.

A 41-year-old man with comorbid binge-eating disorder, severe obesity, and bipolar disorder since the age of 20 years, resistant to drug and psychotherapy combinations, worsened progressively. Relentless weight gain forced him to immobility and dependence on others. He was hospitalized for a mixed-mood episode with anxiety, mystical delusions, and auditory hallucinations. To overcome treatment resistance, we suggested electroconvulsive therapy. After 1 electroconvulsive therapy cycle, psychological symptoms promptly improved. He received clozapine and lithium. After 2 years, he reached normal weight and fair psychopathological compensation.

Effectiveness of electroconvulsive therapy in a patient with a treatment-resistant major depressive episode and comorbid body dysmorphic disorder.

A 24-year-old man experiencing comorbid body dysmorphic disorder since age 16 years, complicated in recent months by a major depressive episode with psychotic features, showed resistance to various drug and psychotherapy combinations. We suggested electroconvulsive therapy (ECT) to overcome treatment resistance. After 1 ECT cycle, mood and anxiety symptoms improved significantly, delusional interpretations and ideas of reference subsided, and dysmorphophobic symptoms improved as well. Six months later, the patient was doing well with a mood stabilizer/antipsychotic combination. Electroconvulsive therapy may improve symptoms of comorbid body dysmorphic disorder along with mood improvement in treatment-resistant depressive disorder.

Structural neuroimaging in patients with panic disorder: findings and limitations of recent studies.

BACKGROUND: Panic disorder, a relatively common anxiety disorder, is often associated to agoraphobia and may be disabling. Its neurobiological underpinnings are unknown, despite the proliferation of models and hypotheses concerning it; investigating its correlates could provide the means for better understanding its pathophysiology. Recent structural neuroimaging techniques may contribute to the identification of possible brain morphological alterations that could be possibly related to the clinical expression of panic disorder. METHODS: Through careful major database searches, using terms keen to panic, agoraphobia, structural magnetic neuroimaging and the like, we identified papers published in peer-review journals and reporting data on the brain structure of patients with panic disorder. Included papers were used comparatively to speculate about the nature of reported brain structural alterations. RESULTS: Anxiety, which is the core feature of the disorder, correlates with the function of the amygdala, which showed a smaller volume in patients, as compared to healthy subjects. Data also showed a volumetric decrease of the anterior cingulate along with increased fractional anisotropy, and increase of some brainstem nuclei, particularly of the rostral pons. Other structures with reported volumetric correlates of panic disorder are the hippocampus and the parahippocampal cortices, the insula, the putamen, and the pituitary gland. Volumetric changes in the anterior cingulate, frontal, orbitofrontal, insular, and temporal cortices have also been described in structural neuroimaging studies. Major methodological limitations are considered in context. CONCLUSIONS: Several data point to the existence of structural neuroanatomical alterations in panic disorder, consisting in significant volumetric reductions or increases in different brain areas. White matter alterations were shown also in the only diffusion tensor imaging study performed to date. Available data do not allow us to conclude about the possible progression of these alterations.

[Functional neuroimaging of the amygdala: the response to threatening and phobogenic stimuli]. / Neuroimaging funzionale dell'amigdala: la risposta a eventi minacciosi o fobigeni.

Recent functional neuroimaging studies show that the amygdala has a central role in threat evaluation, in response to conditioned and unconditioned stimuli, in fear learning and fear extinction. The amygdala is involved in the pathophysiology of phobias and anxiety. In this review we critically examine the main findings of functional neuroimaging studies reporting data on the amygdala. Findings suggest that the response of the amygdala to threatening stimuli is mainly modulated by the infralimbic and prefrontal cortices, which inhibit activation of the amygdala (top-down inhibition), and by the hippocampus, the function of which is related to stimulus learning. The activity of the amygdala is modulated by various factors, like stimulus type and origin, emotion triggered by stimulus perception, and attention. The neural network comprising the amygdala and the frontal cortex is involved not only in top-down inhibition, but also in the emotional perception of facial expressions. This network also includes the thalamic pulvinar, which is densely interconnected with the amygdala, directly or indirectly, and which is activated by emotional face recognition of scary fear. Both top-down inhibition mechanisms and emotional face recognition are altered in anxiety disorders, particularly in specific and social phobia, resulting in reduced amygdalar activity inhibition after anxiety - or fear - inducing stimulus perception. Future functional neuroimaging studies will be able to provide new insights of normal and altered neurophysiology of the amygdala.

Functional neuroimaging in specific phobia.

Specific phobias (SPs) are common, with lifetime prevalence estimates of 10%. Our current understanding of their pathophysiology owes much to neuroimaging studies, which enabled us to construct increasingly efficient models of the underlying neurocircuitry. We provide an updated, comprehensive review and analyze the relevant literature of functional neuroimaging studies in specific phobias. Findings are presented according to the functional neuroanatomy of patients with SPs. We performed a careful search of the major medical and psychological databases by crossing SP with each neuroimaging technique. Functional neuroimaging, mostly using symptom provocation paradigms, showed abnormal activations in brain areas involved in emotional perception and early amplification, mainly the amygdala, anterior cingulate cortex, thalamus, and insula. The insula, thalamus and other limbic/paralimbic structures are particularly involved in SPs with prominent autonomic arousal. Emotional modulation is also impaired after exposure to phobic stimuli, with abnormal activations reported for the prefrontal, orbitofrontal and visual cortices. Other cortices and the cerebellum also appear to be involved in the pathophysiology of this disorder. Functional neuroimaging identified neural substrates that differentiate SPs from other anxiety disorders and separate SP subtypes from one another; the results support current Diagnostic and Statistical Manual of Mental Disorders, 4th edition-Text Revision (DSM-IV-TR) diagnostic subtyping of SPs. Functional neuroimaging shows promise as a means of identifying treatment-response predictors. Improvement in these techniques may help in clarifying the neurocircuitry underlying SP, for both research and clinical-therapeutic purposes.

The wnt pathway in mood disorders.

OBJECTIVES: To review the evidence of the involvement of the Wnt signalling pathway in mood disorders and in the action of drugs used to treat these disorders. METHODS: We performed a careful PubMed search using as keywords all possible terms relevant to the Wnt pathway and crossing them with each of four areas, i.e., developmental effects, behavioural effects, mood disorders, and drugs used in their treatment. Papers were selected on the basis of their content and their data used for discussion. RESULTS: Neurodevelopmental and behavioural data point to the possibility of involvement of the Wnt pathway in the pathophysiology of mood disorders. Clinical and post-mortem data are not sufficient to corroborate a definite role for Wnt alterations in any mood disorder. Combining genetic and pharmacological data, we may state that glycogen synthase kinase is the key molecule in bipolar disorder, as it is connected with many other signalling pathways that were shown to be involved in mood disorders, while Wnt molecules in the hippocampus appear to be mainly involved in depressive disorders. CONCLUSIONS: Altered Wnt signalling may play a role in the pathophysiology of mood disorders, although not a central one. It is premature to draw conclusions regarding the possible usefulness of Wnt manipulations in the treatment of mood disorders.

Successful and rapid response to electroconvulsive therapy of a suicidal patient with comorbid bipolar I disorder and histrionic personality disorder.

A woman with bipolar disorder I, histrionic personality disorder, and suicidal ideation with repeated suicide attempts, who had been treated for 2 years with mood stabilizers, antipsychotics, and benzodiazepines, received a total of 8 bitemporal-biparietal electroconvulsive therapy sessions. Her suicidal ideation and self-harm behavior disappeared immediately after the first session and her psychopathology soon after. This supports the existence of a relatively independent suicidal syndrome and confirms data on its immediate responsiveness to electroconvulsive therapy. Electroconvulsive therapy must not be long withheld from patients with such characteristics to reduce unnecessary sufferance and suicidality.

Electroconvulsive therapy in a physically restrained man with comorbid major depression, severe agoraphobia with panic disorder, and histrionic personality disorder.

A 36-year-old man with comorbid panic disorder with agoraphobia, major depression, and histrionic personality disorder since age 21 was resistant to combined drug and psychotherapy treatment. His conditions had progressively worsened with time, causing him to withdraw socially and to simultaneously require continuous physical restraint, which further worsened his functioning. He spent almost 3 consecutive years in restraint, until he consented to receive bilateral ECT treatment. He improved after 13 sessions in all areas (social and role functioning, and panic, depressive, and histrionic symptoms) and is well 3 months later with a lithium-atypical antipsychotic combination.

Duloxetine in the treatment of elderly people with major depressive disorder.

INTRODUCTION: The elderly population is more frequently subjected to depressive mood compared to the general population and show peculiarities affecting responsiveness; furthermore, aged people need also special care. Duloxetine is a relatively new antidepressant that proved to be effective in adult depression, but has received little attention in elderly population heretofore. AIM: To review the evidence of duloxetine in late-life major depressive disorder (MDD). METHOD: A systematic review of studies focusing on the use of duloxetine in MDD in the elderly has been carried out through the principal specialized databases, including PubMed, PsycLIT, and Embase. RESULTS: Only a handful of papers were specifically dedicated to this issue. Duloxetine was found to be effective and safe in old-age MDD, to be better than placebo on many clinical measures in all studies, and to better differentiate from placebo with respect to selective serotonin reuptake inhibitors. Compared to placebo, its side-effect profile is slightly unfavorable and its drop-out rate is slightly higher. Furthermore, when pain is present in old-age MDD, duloxetine is able to reduce it. CONCLUSIONS: The efficacy and safety of duloxetine in old-age depression are similar to those encountered in adult MDD. There is a relative lack of comparative studies other than with placebo. The special needs of elderly patients with MDD must be addressed with close patient contact to avoid the perils of inappropriate dosing.

Life-saving electroconvulsive therapy in a patient with near-lethal catatonia.

A young woman with bipolar I disorder and comorbid catatonia on enteral nutrition from several months, developed a form of near-lethal catatonia with weight loss, pressure sores, muscle atrophy, electrolyte imbalance, and depression of vital signs. A compulsory treatment was necessary, and informed consent was obtained from her mother for electroconvulsive therapy (ECT). After 7 ECT sessions, the patient recovered and resumed feeding. ECT may save the life of a patient with catatonia provided that legal obstacles are overcome. Clinicians should carefully evaluate patients with near-lethal catatonia, taking into account the risk of pulmonary embolism and other fatal events. The medical-legal issues, which vary across state regulations, should be addressed in detail to avoid unnecessary and potentially harmful delay in intervention.

Personality changes after Toscana virus (TOSV) encephalitis in a 49-year-old man: A case report.

Toscana virus (TOSV) infection may often cause symptomatic meningitides and encephalitides. These usually subside in few days and their sequelae do not last for more than few weeks. We here report the case of a 49-year-old man who developed encephalitis after being bitten by phlebotomi in a region near southern Tuscany, where TOSV is endemic, and who developed postencephalitic seizures and subsequently, persistent personality alterations, characterized by sexually dissolute behavior and aggressiveness. One year after infection, the patient needs a combination of an SSRI antidepressant and a mood stabilizer/anticonvulsant to obtain less than optimal symptom improvement. This points to the need of establishing better preventive measures in Tuscany and nearby regions.

Effectiveness of long-acting risperidone in a patient with comorbid intellectual disability, catatonic schizophrenia, and oneiroid syndrome.

A patient with comorbid intellectual disability, catatonic schizophrenia, and recurrent oneiroid state of consciousness improved on long-acting risperidone and remains well at the three-year follow-up. We report a case treated with 50 mg long-acting risperidone administered every 14 days, who has been followed-up for three years. We studied his regional cerebral blood flow through technetium-99 m hexamethylpropyleneamine oxime single-photon emission computed tomography after two years of treatment. Symptoms of catatonic schizophrenia improved after two months of treatment, followed suit by oneiroid syndrome remission. Two years later, his brain perfusion was normal. No side effect has occurred since the patient was started on long-acting risperidone. Long-acting risperidone proved to be safe and effective in treating symptoms of catatonia and oneiroid syndrome.
