David A Kahn
Antibody-mediated encephalopathies associated with serum or cerebrospinal fluid antibodies directed against neuronal structures may present with a multitude of neuropsychiatric syndromes. Although some of the antibody-driven conditions are now well recognized in adults (eg, N-methyl-D-aspartate receptor antibody encephalitis), the spectrum of neuropsychiatric manifestations in the pediatric population is less clear. Psychosis, confusion, catatonia, and additional behavioral changes, along with seizures, encephalopathy, and movement disorders, may be initial manifestations or concurrent features in all age groups...

REVIEW
Melissa Maguire, Jasvinder Singh, Anthony Marson
The psychoses of epilepsy can be classified according to their temporal relationship with seizures, namely as ictal, postictal and interictal psychosis. Interictal psychosis is the most common and may resemble schizophrenia. They can be challenging to diagnose and to manage, especially given the perception that some antipsychotic drugs may exacerbate seizures, while some antiepileptic medications may worsen psychosis. The current uncertainty around their best management means that some patients may not receive appropriate care...

BACKGROUND: People from culturally and linguistically diverse (CALD) backgrounds are over-represented in compulsory admissions to hospital but little is known about whether this also applies to community treatment orders (CTOs). AIMS: We investigated any differences between Australian- and foreign-born patients in the likelihood of CTO placement using state-wide databases from Western Australia. METHODS: Cases and controls from administrative health data were matched on age, sex, diagnosis and time of hospital discharge (the index date)...

BACKGROUND: Firearm-related suicides comprise over two-thirds of gun-related violence in the United States, and gun laws and policies remain under scrutiny, with many advocating for revision of the regulatory map for lawful gun ownership, aiming at restricting access and distribution of these weapons. However, the quantitative relationship between how strict gun laws are and the incidence of firearm violence with their associated mortality is largely unknown. We therefore, sought to explore the impact of firearm law patterns among states on the incidence and outcomes of firearm-related suicide attempts, utilizing established objective criteria...

BACKGROUND: Bipolar disorder (BD) is a major psychiatric illness characterized by heterogeneous symptoms including psychotic features. Up until now, neuroimaging studies investigating cerebral morphology in patients with BD have underestimated the potential impact of psychosis on brain anatomy in BD patients. In this regard, psychotic and non-psychotic BD may represent biologically different subtypes of the disorder, being possibly associated with specific cerebral features. METHODS: In the present study, magnetic resonance imaging (MRI) at 3T was used to identify the neuroanatomical correlates of psychosis in an International sample of BD patients...

BACKGROUND: Despite high rates of youth suicide attempt, little is known about patterns of functional impairment in terms of sickness absence and disability pension (SA/DP) before and after an attempt. The aim was to identify SA/DP trajectories among young adults with or without suicide attempt and to describe associations of socio-demographic and clinical factors with such trajectories. METHODS: This is a population-based cohort study of 5385 individuals aged 25-40 years with a first suicide attempt during 2007-2009...

Importance: Psychotic disorders contribute significantly to the global disease burden, yet the latest international incidence study of psychotic disorders was conducted in the 1980s. Objectives: To estimate the incidence of psychotic disorders using comparable methods across 17 catchment areas in 6 countries and to examine the variance between catchment areas by putative environmental risk factors. Design, Setting, and Participants: An international multisite incidence study (the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions) was conducted from May 1, 2010, to April 1, 2015, among 2774 individuals from England (2 catchment areas), France (3 catchment areas), Italy (3 catchment areas), the Netherlands (2 catchment areas), Spain (6 catchment areas), and Brazil (1 catchment area) with a first episode of nonorganic psychotic disorders (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision [ICD-10] codes F20-F33) confirmed by the Operational Criteria Checklist...

Jean Stafford, Robert Howard, James B Kirkbride
A substantial subset of people with psychotic disorders are first diagnosed in old age, yet little is known about the epidemiology of very late-onset schizophrenia-like psychosis. We investigated the incidence of affective and non-affective psychotic disorders in those aged 65 and above, and examined variation related to potential risk factors via systematic literature review. We searched PubMed, PsychInfo, Web of Science and bibliographies and directly contacted authors to obtain citations published between 1960 and 2016 containing (derivable) incidence data...

BACKGROUND: The boundary between Dermatology and Psychiatry has increasing recognition. Psoriasis is a common psychophysiological skin disease with a major impact on patient's quality of life and a paradigmatic example of a pathology in that boundary. Studies are needed to exactly point out the prevalence of specific psychopathology and mental disorders associated with psoriasis. This work intends to analyse the prevalence of psychopathology and psychiatric comorbidities in patients with psoriasis...

Experience of intimate partner violence (IPV) can lead to mental health conditions, including anxiety, depression, and unhealthy substance use. Women seen in the Veterans Health Administration (VHA) face high rates of both IPV and mental health morbidity. This study aimed to identify associations between recent IPV experience and mental health diagnoses among women VHA patients. We examined medical records data for 8,888 female veteran and nonveteran VHA patients across 13 VHA facilities who were screened for past-year IPV between April, 2014 and April, 2016...

Sigma-1 (σ1) receptor has been identified as a chaperone protein that interacts with other proteins, such as N-methyl-D-aspartate (NMDA) and opioid receptors, modulating their activity. σ1 receptor antagonists have been developed to obtain useful compounds for the treatment of psychoses, pain, drug abuse and cancer. Some interesting compounds such as E-5842 (5) and MS-377 (24), haloperidol and piperazine derivatives, respectively, were endowed with high affinity for σ1 receptors (Ki σ1 = 4 and 73 nM; Ki σ2 = 220 and 6900, respectively)...

Alfred Walter Campbell (1868-1937) established the basic cytoarchitectonic structure of the human brain while he was working as a pathologist at the Rainhill Lunatic Asylum near Liverpool in the United Kingdom. He returned to Australia in 1905 and continued doing research while establishing a neurological practice. His research over the next 17 years focused on four topics: (a) localisation in the cerebellum, (b) the neuroses and psychoses in war, (c) localisation in the cerebral cortex of the gorilla, and (d) the causes and pathology of the mysterious Australian "X" Disease (later known as Murray Valley encephalitis)...

We can trace, with high congruence, the clinical syndromes of depression and mania as described over the 20th century in psychiatric textbooks back to 1880 and to the earliest writing of Kraepelin published in 1883. However, this is not the case for Kraepelin's 2 delusional syndromes central to his overall nosology: Dementia Paranoides (later paranoid schizophrenia) and Paranoia. A detailed examination of 28 textbook descriptions of delusional psychoses from 1880 to 1900 reveals a diverse and partially overlapping set of syndromes with an admixture of symptoms and signs that would later be considered indicative of Dementia Paranoides and Paranoia...

Purpose of the article: There are indications of altered immune activity in depressed and psychotic patients compared to healthy controls in several studies. To explore the clinical importance of this phenomenon we examined the relation between different disorders affecting the immune system and psychoses and depression, respectively. MATERIALS AND METHODS: A total of 276 patients consecutively admitted to a psychiatric acute ward were included in the study. Of these 41 patients fulfilled the criteria for ICD-10 F20-29 (psychotic) diagnosis and 157 patients a F30-39 (affective) diagnosis...

The motility psychoses are a group of acute psychiatric conditions characterized by salient disorders of movement (increased, decreased and disorganized), psychotic experiences, confusion and good prognosis. The debate on whether they are just atypical forms of schizophrenia or manic-depressive insanity or constitute an independent group of psychoses has not yet been settled. Erik Strömgren's classical chapter deals with the history and clinical aspects of the motility psychoses. Based on a historical analysis and an empirical study of a patient cohort, the author draws conclusions on the nature of this clinical group that has stood the test of time well...

BACKGROUND: France has a complex system for the taxation of alcoholic beverages. In the French overseas territories (FOT), the system includes little-known specificities whose purpose is to preserve the sugar-cane-rum sector, a pillar for the weak economies in these territories. Taxes are reduced for traditional rums produced and sold locally. This favors the marketing of alcoholic spirits at low prices. In metropolitan France, on the contrary, spirits are heavily taxed drinks and their share in consumption is minor...
