Self-harm (SH; intentional self-poisoning or self-injury) is common in children and adolescents, often repeated, and strongly associated with suicide. This is an update of a broader Cochrane review on psychosocial and pharmacological treatments for SH published in 1998 and updated in 1999. We have now divided the review into three separate reviews; this review is focused on psychosocial and pharmacological interventions for SH in children and adolescents.

As in adults, self-harm in children and young people is common. It results in much distress to families and carers, and considerable morbidity among children and young people. Although much more common than completed suicide, it is strongly linked to repeated self-harm and suicide. The conclusions in this review are limited by the small number of studies included, no studies of pharmacological interventions at all and most of the included interventions being evaluated in a single study. One moderately sized study of mentalisation in adolescents with comorbid depression showed a significant effect on scores on a self-harm measure, indicating fewer self-reported episodes of self-harm. No other intervention showed a significant reduction in reported self-harm, although trials may have been too small to show statistical significance.

This article examines the clinical, epidemiological and nosological aspects of short-lived psychotic disorders as currently classified under ‘acute and transient psychotic disorders' in ICD-10 and ‘brief psychotic disorder’ in DSM-5. After describing earlier diagnostic concepts such as bouffée délirante, cycloid psychosis, reactive psychosis and schizophreniform psychosis, we present an overview of the literature and discuss implications for classification, diagnosis and treatment of these conditions, pointing out differences from longer-lasting psychotic disorders.

There is now an established evidence base for the use of information and communication technology (ICT) to support mental healthcare (‘e-mental health’) for common mental health problems. Recently, there have been significant developments in the therapeutic use of computers, mobile phones, gaming and virtual reality technologies for the assessment and treatment of psychosis. We provide an overview of the therapeutic use of ICT for psychosis, drawing on searches of the scientific literature and the internet and using interviews with experts in the field. We outline interventions that are already relevant to clinical practice, some that may become available in the foreseeable future and emerging challenges for their implementation.

Research into the use of digital technology to deliver treatment for psychosis is turning up some fascinating applications, but enthusiasm for these products must be tempered with a realistic appraisal of the steps from initial proof of concept to a marketable device.

The language of psychiatry can be ambiguous and idiosyncratic, reflecting the elastic borders of mental illness and psychiatric disorder. This problem is not unique to psychiatry, but as the medical specialty moves closer towards a 'spectrum view’ of mental illness, psychiatric terminology increasingly risks misappropriation and conflation with lay concepts of normal suffering. Deciding what words mean and how psychiatric disorders are defined requires ongoing consideration of the pragmatic consequences, both intended and unintended. Refining the lexicon of psychiatry with an eye towards precision and the minimisation of stigma requires that terms be revised and updated from time to time, but often suitable word replacements remain elusive.

Autism and schizophrenia were placed in different diagnostic categories in DSM-III, having previously been considered as related diagnostic entities. New evidence suggests that these disorders show clinical and cognitive deficit overlaps and shared neurobiological characteristics. Furthermore, children presenting with both autism spectrum disorder (ASD) and psychotic experiences may represent a subgroup of ASD more closely linked to psychosis. The study of ASD and childhood schizophrenia, and their clinical boundaries and overlapping pathophysiological characteristics, may clarify their relationship and lead to more effective interventions. This article discusses the relationship through a critical review of current and historical dilemmas surrounding the phenomenology and pathophysiology of these disorders. It provides a framework for working with children and young people with mixed clinical presentations, illustrated by three brief fictional case vignettes.

Patients presenting to psychiatrists frequently have comorbid medical conditions for which they are receiving treatment. A range of medications used for treatment of these conditions can have adverse effects resembling psychiatric symptoms. This article presents the results of our review of the literature on psychiatric adverse effects of various non-psychotropic medications, and discusses the mechanisms of such effects, their assessment and management. Among the commonly prescribed drugs found to have psychiatric adverse effects are corticosteroids, anti-Parkinsonian drugs, anti-epileptics, antiretrovirals, antibiotics, anticancer drugs, analgesics, drugs targeting endocrine and cardiovascular disorders, immunosuppressants, skeletal muscle relaxants and bronchodilators. Some adverse effects are predictable and dose dependent, whereas others are rare and idiosyncratic, and psychiatrists need to be aware of them for accurate diagnosis and appropriate treatment.

The presentation of anxiety disorders in children and adolescents shares similarities and differences with that in adults, and may vary significantly, depending on the age of the individual. Assessment must differentiate anxiety disorders from developmentally appropriate fears as well as medical conditions and drugs that can mimic anxiety states. Aetiology of anxiety disorders in this group encompasses complex genetic and environmental influences. Additional insight into causation is provided by neuroimaging and research into temperament. Recommended interventions include both cognitive-behavioural therapy and pharmacology. Although childhood anxiety disorders generally remit, there remains an increased risk for anxiety and depressive disorders to emerge in adulthood, most likely through heterotypical continuity.

The novels of the Icelandic Nobel laureate Halldór Laxness depict individuals who are confronted by personal, familial and societal challenges in an isolated, sparsely populated and unpredictable but sublime and almost magical land. Novels which are currently available in English translation carefully illustrate the potentially damaging consequences of parentlessness, childhood abuse, physical illness, unexpected bereavement and marital desertion; the often corrosive effects of social and economic inequality; and the undermining of the lives and aspirations of women by patriarchal institutions. The Great Weaver from Kashmir is probably his least well-known novel but addresses many of these themes: most of its characters fall by the wayside and only a few thrive on adversity.

Peer-supported open dialogue is a variant of the ‘open dialogue’ approach that is currently practised in Finland and is being trialled in several countries around the world. The core principle of the approach is the provision of care at the social network level, by staff who have been trained in family, systems and related approaches. These staff include peer workers, who will help to enhance the democratic nature of the meetings around which care is centred, as well as enabling such meetings to occur where networks are fragmented or lacking. Certain organisational and practice features and underlying themes are key to the approach. Crucially, open dialogue is also a system of service provision. Staff trained in peer-supported open dialogue from six National Health Service (NHS) trusts will launch pilot teams in 2016, as part of an intended national multicentre randomised controlled trial.
