Most evidence on TCAs relates to desipramine. Findings suggest that, in the short term, desipramine improves the core symptoms of ADHD, but its effect on the cardiovascular system remains an important clinical concern. Thus, evidence supporting the clinical use of desipramine for the treatment of children with ADHD is low.

SUMMARYAvoidant/restrictive food intake disorder (ARFID) was a new diagnosis in DSM-5 and is due to be included in ICD-11. However, confidence in making the diagnosis seems to be low among clinicians. Furthermore, there is no national consensus on care pathways for ARFID and therefore patients tend to be managed across core child and adolescent mental health services, specialist eating disorder services and paediatric services. If not adequately treated, ARFID can result in stunted growth, nutritional deficiency and impaired psychosocial functioning. Research and guidelines for managing this disorder are scarce, owing to low rates of diagnosis. This article aims to improve clinician confidence in the use of ARFID as a diagnosis and explores current consensus on treatment approaches, in order to progress future service planning for this complex and diverse patient group.LEARNING OBJECTIVES•Gain an improved knowledge of the diagnostic criteria for ARFID•Know how to distinguish ARFID from other eating disorders•Understand the current consensus on treatment approaches for ARFIDDECLARATIONS OF INTERESTNone.

Pervasive refusal syndrome (PRS) is a complex condition that affects young people leading to social withdrawal, inability or refusal to eat, drink, mobilise or speak. The affected individual regresses and is unable to self-care and quite characteristically will resist rehabilitation, worsen with praise or remain entirely passive. This systematic review was aimed at describing clinical features of PRS, current interventions and to summarise some of the nosological aspects of the condition. Without language restriction, an electronic search was conducted in Embase, PsychInfo, Medline, Cochrane library, and PubMed databases yielding 29 articles with a total of 79 cases. We performed a risk of assessment bias using an adapted Newcastle-Ottawa Scale and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. 124 articles were identified, of which 29 were included and these yielded 79 cases. Seventy-six percent of the studies had a low rate of risk of assessment bias (good quality). Our results show that PRS overlaps with several conditions, mainly affects young females aged 7-15 years and has a recovery rate of 78% if diagnosed and treated early but the duration of inpatient treatment may last up to 9.44 months (8.82 SD). The patients had multiple inter-dependent risks. The major predisposing factors included vulnerable premorbid personality and pre-existing mental disorder. Precipitating factors were stressors such as infection and traumatic experiences. Enmeshed parent-child relationship served as a maintaining factor. The themes of treatment approach are essentially rehabilitative: (1) working collaboratively with patient and family, (2) having access to multidisciplinary team, and (3) peer/group supervision. This study has systematically evaluated a large sample of patients with PRS to ascertain its clinical features and the core elements of its treatment. Its key treatment approach is a multi-modal rehabilitative strategy that is compassionate, transparent and inclusive.

Aims and methodAll child and adolescent psychiatrists and community paediatricians in the former Trent Region were surveyed about their antipsychotic prescribing practice during 1 year, including monitoring, and whether they would like consensus guidelines on prescribing and monitoring of antipsychotics in children and adolescents.ResultsThe majority (88%) of child psychiatrists and 33% of paediatricians had prescribed atypical antipsychotics, most commonly risperidone. Only two psychiatrists had prescribed a typical antipsychotic and no paediatrician had done so. Challenging behaviour in developmental disorders was the most common indication for atypicals. Both child psychiatrists and paediatricians prescribed atypicals for non-psychotic developmental disorders, whereas prescribing for psychosis occurred almost exclusively among psychiatrists. Height, weight and blood pressure were routinely monitored, but waist circumference was rarely measured and there was wide variation in the monitoring of other parameters such as blood glucose, prolactin and extrapyramidal side-effects. Three-quarters of the participants felt there was a need for guidance on prescribing and monitoring atypical antipsychotic therapy.Clinical implicationsThe greater prescription of antipsychotics by child and adolescent psychiatrists may reflect differences in case-load and training. Routine monitoring of adverse effects is inconsistent among prescribers. The survey highlights the need for training and guidance on prescribing and monitoring of atypical antipsychotic use in children and adolescents.

SUMMARY Dual diagnosis is one of several terms used to identify individuals diagnosed with a co-occurring mental disorder and substance use disorder. The existence of a dual diagnosis in adolescents is often associated with functional impairment in various life domains, causing physical health problems, relational conflicts, educational/vocational underachievement and legal problems. Dual diagnosis is difficult to treat and can result in tremendous economic burden on healthcare, education and justice systems. It is essential for clinicians caring for young people to be knowledgeable about dual diagnosis to ensure that it is identified early and treated. This article aims to provide an overview of dual diagnosis, increase its awareness and promote a realistic treatment approach.
