Efficacy and Effectiveness of Child and Adolescent Psychotherapy and Pharmacotherapy

Decades of intervention research have produced a rich body of evidence on the effects of psychotherapies and pharmacotherapies with children and adolescents. Here we summarize and critique that evidence. We review findings bearing on the efficacy of psychosocial treatments and medications under controlled experimental conditions. We also report evidence, where available, on the effectiveness of both classes of treatment with clinically referred youth treated in real-world clinical contexts. In general, the large body of evidence on efficacy contrasts sharply with the small base of evidence on effectiveness. Addressing this gap through an enriched research agenda could contribute importantly to linking scientific inquiry and clinical practice—to the benefit of both ventures. This is one element of a multifaceted agenda for future research and for synthesis of research, which will require the interplay of multiple disciplines related to child and adolescent mental health.     

Cultural Identity and Experiences of Prejudice and Discrimination of Afghan and Iranian Immigrant Youth

In culturally diverse and immigrant receiving societies, immigrant youth can be subject to prejudice and discrimination. Such experiences can impact on immigrant youth’s cultural identity and influence their psychosocial outcomes. This paper presents findings of a study that examined cultural identity and experiences of prejudice and discrimination among Afghan (N = 9) and Iranian (N = 17) immigrant youth in Canada. The study had a prospective, comparative, longitudinal qualitative design. Data was gathered through focus groups, interviews, journals and field logs. Four main themes emerged on participants’ experiences of prejudice and discrimination: (a) societal factors influencing prejudice; (b) personal experiences of discrimination; (c) fear of disclosure and silenced cultural identity; and (d) resiliency and strength of cultural identity. Drawing from Rosenberg’s (Conceiving the self, Basic Books, New York, 1979) self-concept framework and Romero and Roberts (J. Adolesc., 21:641–656, 1998) distinction between prejudice and discrimination, results indicated that youth’s extant and presenting cultural identity were affected. Inclusive policies and practices are needed to promote youth integration in multicultural and immigrant receiving settings.

Design and pharmacological activity of glycinamide and N-methoxy amide derivatives of analogs and constitutional isomers of valproic acid

A series of glycinamide conjugates and N-methoxy amide derivatives of valproic acid (VPA) analogs and constitutional isomers were synthesized and evaluated for anticonvulsant activity. Of all compounds synthesized and tested, only N-methoxy-valnoctamide (N-methoxy-VCD) possessed better activity than VPA in the following anticonvulsant tests: maximal electroshock, subcutaneous metrazol, and 6-Hz (32-mA) seizure tests. In mice, the ED₅₀ values of N-methoxy-VCD were 142 mg/kg (maximal electroshock test), 70 mg/kg (subcutaneous metrazol test), and 35 mg/kg (6-Hz test), and its neurotoxicity TD₅₀ was 118 mg/kg. In rats, the ED₅₀ of N-methoxy-VCD in the subcutaneous metrazol test was 36 mg/kg and its protective index (PI = TD₅₀/ED₅₀) was > 5.5. In the rat pilocarpine-induced status epilepticus model, N-methoxy-VCD demonstrated full protection at 200 mg/kg, without any neurotoxicity. N-Methoxy-VCD was tested for its ability to induce teratogenicity in a mouse strain susceptible to VPA-induced teratogenicity and was found to be nonteratogenic, although it caused some resorptions. Nevertheless, a safety margin was still maintained between the ED₅₀ values of N-methoxy-VCD in the mouse subcutaneous metrazol test and the doses that caused the resorptions. On the basis of these results, N-methoxy-VCD is a good candidate for further evaluation as a new anticonvulsant and central nervous system drug.     

Review and meta-analysis of the phenomenology and clinical characteristics of mania in children and adolescents

OBJECTIVE: Using predetermined criteria for study quality and methods, a literature review and meta-analysis of seven reports about pediatric bipolar disorder (BPD) was conducted to determine if there is a consistent picture of the phenomenology and clinical characteristics of BPD in children and adolescents. METHODS: Searches were conducted in MedLine and PsycINFO using the terms mania, BPD, children and adolescents, and was limited to published articles in peer-reviewed journals. Seven reports were selected that met the following criteria: a systematic method for the elicitation and reporting of symptoms and clinical characteristics of subjects; subjects were interviewed by a trained researcher or clinician; ages 5-18 years; use of a diagnostic system, either DSM or RDC for categorization; a consensus method for the establishment of the diagnosis of BPD. RESULTS: Most DSM-IV symptoms of mania were common in the children and adolescents with BPD with the most common symptoms being increased energy, distractibility, and pressured speech. On average, four of five bipolar cases also showed threshold levels of irritable mood and grandiosity, and more than 70% of all cases showed elated/euphoric mood, decreased need for sleep, or racing thoughts. Roughly 69% of cases also showed poor judgment, whereas only half of bipolar cases demonstrated flight of ideas, and slightly more than one-third showed hypersexuality or psychotic features. CONCLUSIONS: The clinical picture that emerges is that of children or adolescents with periods of increased energy (mania or hypomania), accompanied by distractibility, pressured speech, irritability, grandiosity, racing thoughts, decreased need for sleep and euphoria/elation.     

Long-term health and socioeconomic consequences of childhood and adolescent-onset of narcolepsy

ObjectivesThere is limited information about the long-term consequences of childhood- and adolescent-onset narcolepsy on educational and social factors. Here, we estimate the long-term socioeconomic consequences and health care costs of narcolepsy.MethodsThe prospective cohort study included Danish individuals with narcolepsy onset in childhood or adolescence, diagnosed between 1994 and 2015. Health care costs and socioeconomic data were obtained from nationwide administrative and health registers. One hundred seventy-one patients were compared with 680 controls (mean index age, 15.2 years; SD, 3.4 years) matched for age, gender, and other sociodemographic characteristics.ResultsComparing the narcolepsy patient and control groups at age 20 years we found: (1) no differences in parental educational level; (2) patients had a significantly lower educational level than controls; (3) patients had significantly lower grade-point averages; (4) patients had a lower employment rate and lower-income, even when transfer payments were considered; and (5) patients' initial health care costs were higher. Patients had a higher mortality rate than controls, although the difference was not statistically significant.ConclusionNarcolepsy is associated with a significant influence on educational level, grading, social outcome, and welfare consequences. The development of narcolepsy is independent of parental social level.     

Effects of Agonists and Antagonists of Cholecystokinin on Contractile and Myoelectric Activity of Isolated Muscle of Colon and Ileum in the Dog and Guinea Pig

This study evaluates the effects of agonists and antagonists of cholecystokinin (CCK) on contractile and myoelectrical activity in isolated longitudinal muscle strips from colon or ileum of guinea pigs or beagle dogs. Caerulein and CCK-8 caused a dose-dependent increase of contractile and myoelectrical spike activity in both species with maximal effects seen between 10⁻⁸ and 3 × 10⁻⁸ M. The dose responses were identical for both CCK agonists and species. The dose-related effects of CCK compounds on colonic muscle were slightly shifted to the right when compared to ileum in both species. All antagonists, the proglumide-derivatives CR1409, CR1392, and CR1505, as well as the nonpeptide substances asperlicin and L-364,718, caused a parallel rightward shift of CCK's dose-dependent motor activity response, indicating the competitive nature of inhibition. The antagonists displayed a rank order of potency in antagonizing CCK's action on intestinal motility similar to their ability to antagonize CCK's action on pancreas and gallbladder. L-364,718 was the most potent antagonist, followed by CR1409, CR1505, CR1392, asperlicin, and proglumide. The antagonists did not affect contractile or myoelectrical responses to acetylcholine, histamine, motilin, or substance P. Thus compounds that have been described as CCK antagonists for pancreas and gallbladder also act as specific and competitive antagonists of CCK's action on contractile and myoelectrical activity of Heal and colonie muscle.     

The neuroendocrinology of stress and the pathophysiology and therapy of depression and anxiety

Clinical and preclinical studies have gathered substantial evidence that stress response alterations play a major role in the development of major depression, panic disorder, and post-traumatic stress disorder. The stress response, the hypothalamic pituitary adrenocortical (HPA) system and its modulation by corticotropin-releasing hormones (CRH),corticosteroids,and their receptors, and the roles of natriuretic peptides and neuroactive steroids are described. We review the role of the HPA system in major depression, panic disorder, and post-traumatic stress disorder and its possible relevance for treatment. Impaired glucocorticoid receptor function in major depression is associated with an excessive release of neurohormones such as CRH, to which a number of signs and symptoms characteristic of depression can be ascribed. In panic disorder, a role of central CRH in panic attacks has been suggested. Atrial natriuretic peptide (ANP) is causally involved in sodium lactate-induced panic attacks. Furthermore, preclinical and clinical data on its anxiolytic activity suggest that nonpeptidergic ANP receptor ligands may be potentially useful in the treatment of anxiety disorders. Post-traumatic stress disorder is characterized by a peripheral hyporesponsive HPA system and elevated CRH concentrations in the CSF. This dissociation is probably related to an increased risk of this disorder. We further review recent data that describe an important role of GABA(A)-receptor modulatory,3 alpha-reduced neuroactive steroids in major depression, anxiety, and its treatment. Antidepressants are effective in both depression and anxiety disorders and have major effects on the HPA system,especially on glucocorticoid and mineralocorticoid receptors. Normalization of HPA system abnormalities is a strong predictor of the clinical course, at least in major depression and panic disorder. Currently,CRH-R1 or glucocorticoid receptor antagonists and ANP receptor agonists are being studied and may provide future treatment options more closely related to the pathophysiology of these disorders.     

Neurological and neuropsychological consequences of electrical and lightning shock:review and theories of causation

Injuries from lightning and electrical injuries involve multiple systems of the body, however neurological symptoms are very widely reported. A disabling neuropsychological syndrome is also noted.This paper presents a comprehensive review of neurological and neuropsychological symptoms. Partial theories of causation for these injuries have been advanced, however, there is no convincing explanation for both delay in onset of symptoms and also the genesis of the neuropsychological syndrome. A theory of causation is proposed which satisfies both these constraints.This theory suggests circulating hormones such as cortisol, together with nitric oxide and oxidant free radicals from glutamatergic hyper-stimulation, act on tissues remote from the injury path including the hippocampus.This theory opens a research path to explore treat-ment options.     

Establishing reports of saying and doing and discriminations of say-do relations

The purpose of the present study was to investigate a new procedure for establishing accurate discriminations of delayed acts of saying, of doing and discriminations of say-do correspondence and non-correspondence with three developmentally delayed subjects. A corrective feedback procedure for incorrect discrimination responses, that involved multiple-exemplars, was initially employed, but failed to establish most of the target discriminations for all three subjects. A near-errorless training intervention was subsequently employed that also involved multiple-exemplars. This training used two referents (one for acts of saying and another one for acts of doing) as prompts to produce accurate delayed reports of what they promise to do presently, and accurate delayed reports of what they did. Prompts were also used to indicate whether the say-do relations were the 'same' in terms of correspondence or not the same in terms of non-correspondence. Prompts were subsequently eliminated. All three subjects demonstrated highly accurate reports of delayed saying, doing and say-do correspondence or non-correspondence discriminations in the absence of prompts and with novel stimuli. The results are discussed in terms of generalized classes of behavior. The implications of these findings for the use of the errorless learning paradigm as a means of establishing complex behavior are also discussed.     

Morbidity and mortality of middle-aged and elderly narcoleptics

ObjectivesThe objective of the study was to evaluate the morbidities and mortality in a national group of middle-aged and elderly narcolepsy patients before and after the first diagnosis of the condition.MethodsFrom the Danish National Patient Registry (NPR), 1174 patients (45.1% males) aged 20–59 years and 339 patients (44.8% males) aged 60+ who received a diagnosis of narcolepsy between 1998 and 2014 were compared, respectively, with 4716 and 1353 control citizens matched for age, gender and geography, who were randomly chosen from the Danish Civil Registration System Statistics. In the NPR, all morbidities are grouped into major WHO classes.ResultsMiddle-aged and elderly patients had more health contacts before and after their narcolepsy diagnosis with respect to several disease domains: infections, neoplasm, endocrine/metabolic diseases/diabetes, mental/psychiatric, neurological (including epilepsy), eye, cardiovascular (hypertension, ischemic heart disease), respiratory (upper-airway infections, sleep apnea), gastrointestinal, musculoskeletal (including discopathies) and skin diseases. Narcolepsy patients had lower reproductive rates. Furthermore, patients showed significantly more health contacts due to the evaluation and control contacts for disease and symptoms. Patients suffered from significantly more multiple diseases than did controls.The 17-year hazard ratio mortality rates were 1.35 (95% CI, 0.94–1.95, p = 0.106) among 20–59 year-olds, and 1.38 (1.12–1.69, p = 0.002) among those aged 60+ years.ConclusionThere are higher rates of morbidity in several disease domains before and after a diagnosis of narcolepsy. Elderly narcolepsy patients have higher mortality rates.

Anticoagulants and antiplatelet agents and the risk of development and recurrence of chronic subdural haematomas

Seventy-one patients from northern Sweden were diagnosed with chronic subdural haematomas (CSDH) and treated at the Department of Neurosurgery at Umeå University Hospital over 12 months. Fifty-four patients with CSDH had a history of head trauma (trauma group), while 17 patients had no previous head trauma (non-trauma group). In the non-trauma group 71% of patients were treated with anticoagulants or antiplatelet aggregation agents (AAA) compared to 18% in the trauma group. Considering only AAA, 59% of the non-trauma patients were treated with these drugs versus 17% of patients in the trauma group. The recurrence rate for all patients was 17%. These findings confirm that the use of anticoagulants and AAA is over-represented in patients with non-traumatic CSDH. In our study, recurrence was not associated with previous use of anticoagulants or AAA.     

Situation and problem of administration methods and the intermission of hypnotics

The results of a questionnaire survey suggested four problems that might prolong the administration of benzodiazepine hypnotics without suspending the medication. First, psychiatrists did not actively consider the necessity of suspension of medication with hypnotics. Second, the period between improvement of insomnia and initiation of dose reduction was long, whereas the period between initiation of dose reduction and discontinuation was short. Third, to suspend medication of a hypnotic, every-other-day administration was used for the very short-acting and short-acting types, and substitution of the intermediate-acting or long-action type for the drugs with a short half-life were performed frequently. Finally, dose reduction and intermission of medication induced rebound insomnia, withdrawal symptoms, and recurrence of insomnia.     

Pro- and anticonvulsant actions of morphine and the endogenous opioids: Involvement and interactions of multiple opiate and non-opiate systems

The proconvulsant actions of high doses of systemic morphine are probably mediated by 3 different systems. One of them produces non-convulsant electrographic seizures and can be activated separately from the others both by intracerebroventricular injections as well as microinjections into discrete subcortical areas. The enkephalins and β-endorphin, when administered to the same loci, produce similar effects. Pharmacological evidence suggests that specific opiate receptors of the β-subtype mediate the epileptiform effects produced by this system. The second system mediating proconvulsant effects of systemic morphine is not mediated by stereo-specific opiate receptors. It produces behavioral convulsions, and the GABA-ergic system has been implicated in its action. A third proconvulsant action of systemic morphine can be activated separately from the other two systems by administering this compound with other convulsive agents or manipulations. Specific μ-type opiate receptors are implicated in this effect. In addition to potent proconvulsant effects, systemic morphine also has anticonvulsant properties which are mediated by specific opiate μ-receptors. The conditions under which morphine acts as a proconvulsant rather than an anticonvulsant agent are, as yet, not understood.
