Evidence-based guidelines for management of attention-deficit/hyperactivity disorder in adolescents in transition to adult services and in adults: recommendations from the British Association for Psychopharmacology.

Attention-deficit/hyperactivity disorder (ADHD) is an established diagnosis in children, associated with a large body of evidence on the benefits of treatment. Adolescents with ADHD are now leaving children's services often with no readily identifiable adult service to support them, which presents problems as local pharmacy regulations often preclude the prescription of stimulant drugs by general practitioners (GPs). In addition, adults with ADHD symptoms are now starting to present to primary care and psychiatry services requesting assessment and treatment. For these reasons, the British Association for Psychopharmacology (BAP) thought it timely to hold a consensus conference to review the body of evidence on childhood ADHD and the growing literature on ADHD in older age groups. Much of this initial guidance on managing ADHD in adolescents in transition and in adults is based on expert opinion derived from childhood evidence. We hope that, by the time these guidelines are updated, much evidence will be available to address the many directions for future research that are detailed here.

Psychostimulants and psychiatrists: the Trent Adult Psychiatry Psychostimulant Survey.

This study reports upon the results of a postal questionnaire survey of 107 adult psychiatrists which investigated their current use of psychostimulant pharmacotherapy and their attitudes towards the diagnostic status of attention-deficit hyperactivity disorder (ADHD) in adulthood. Of the 88 respondents, only a minority of 11 (12.5%) used psychostimulants in their usual practice, albeit very infrequently (one or two prescriptions per year on average). Methylphenidate hydrochloride ('Ritalin') was the prescribers' most popular agent and 'narcolepsy' was the most frequently cited clinical indication for psychostimulants. ADHD appeared to represent only a very small area of current clinical activity and a minority of clinicians expressed the view that it did not exist in adults. It is concluded that psychostimulant therapy is relatively undeveloped in British adult psychiatry and that the clinical speciality generally appears to be unprepared for the growing numbers of adolescents with ADHD who are currently managed by child psychiatrists and who may require ongoing psychiatric care, including psychostimulant therapy.

American Academy of Pediatrics. Committee on Child Abuse and Neglect and Committee on Community Health Services. Investigation and review of unexpected infant and child deaths.

Although there is a continuing need for timely review of child deaths, no uniform system exists for investigation in the United States. Investigation of a death that is traumatic, unexpected, obscure, suspicious, or otherwise unexplained in a child younger than 18 years requires a scene investigation and an autopsy. Review of these deaths requires the participation of pediatricians and other professionals, usually as a child death review team. An appropriately constituted team should evaluate the death investigation process, review difficult cases, and compile child death statistics.

Cognitive functioning in children with typical cri du chat (5p-) syndrome.

This study is the first attempt to assess systematically the cognitive functioning in children diagnosed with typical cri du chat syndrome (CDCS) using neuropsychological test measures. Twenty-six children aged between 6 years 4 months and 15 years 5 months (mean 8 years 3 months) completed a battery of tasks measuring IQ level, receptive and expressive language skills, and articulation. Twenty-four children were in the severe learning-disability range with no specific verbal or performance profile. Using more finely tuned measures of cognition, however, a clear discrepancy in the pattern of language functioning was found with better receptive than expressive language skills. One implication of these findings is that parents and professionals should be more optimistic about the capacities of children with CDCS to understand more complex verbal commands than their expressive language skills would suggest.

Monoclonal gammopathy of the immunoglobulin A class in a two-year-old girl with ataxia telangiectasia.

Ataxia telangiectasia is an autosomal recessive neurologic disorder which is frequently associated with a deficiency of IgA immunoglobulin. We report an unusual case of monoclonal gammopathy of the IgA kappa type in a 2-year-old female patient newly diagnosed with ataxia telangiectasia. Quantitative analysis of the patient's immunoglobulins revealed a marked elevation in the IgA fraction with a value of 672 mg/dL (normal 14-123 mg/dL). The IgG and IgM fractions were normal. Serum protein electrophoresis showed a band of restricted mobility present in the gamma region, which was identified as a monoclonal IgA kappa immunoglobulin on immunofixation electrophoresis. This is the first case report of a patient with ataxia telangiectasia associated with an IgA monoclonal gammopathy.

Rapid-acting treatment for a common sleep problem.

A behavioural modification package incorporating stimulus control, cueing, and rapid-extinction techniques was applied to a group of 15 children with severe learning disability who had chronic sleep disorders. Improvements in their night-settling and night-waking patterns occurred quickly (within a few days) and, in 12 of them, were sustained at medium- and long-term (18 months) follow-up. Additional improvements in the children's daytime behaviour and their mothers' subjective stress indices were observed, though not explicitly addressed. These results compare favourably with those of other studies which have tested behavioural interventions in other cohorts of children with sleep disorders. Wider application of behavioural interventions with these extremely common and potentially handicapping sleep disorders is recommended.

Case study: Ganser syndrome in children and adolescents.

Six cases of the Ganser syndrome have been previously described in the literature and are reviewed here. They are imperfect representations of the originally described syndrome. This article describes a case of the Ganser syndrome in a 12-year-old boy who, after a mild head injury, presented with three of four of the core symptoms. The nature of the Ganser syndrome remains unclear, but this case study highlights dissociation and abnormal illness behavior as being important in the production of the symptoms. Classically the course is short-lived, although this report raises the possibilities of a much more chronic course.

Consumer opinion concerning the treatment of a common sleep problem.

In an uncontrolled, open, pilot study, 15 severely learning disabled children suffering from severe and lifelong night-settling and night-waking (NS/NW) problems were treated with a brief behavioural modification approach based upon the behavioural therapy principles of rapid extinction, cueing and stimulus control. Following the treatment positive changes in these problems occurred quickly (within a few days) and these were sustained at both the 4- and 18-month follow-up stages in the majority of the children. Despite the misgivings of previous commentators concerning rapid extinction techniques, the children's parents found this treatment approach to be safe, helpful and acceptable. This study explores their views about this form of treatment and also about previous help they had received.

Marked reduction of anemia during pregnancy over a 10-year period in Montserrat.

Anemia during pregnancy is associated with adverse outcomes including maternal and perinatal mortality. However, health education and other public health strategies seeking to reduce its prevalence have usually met with only limited success. The study reported here surveyed anemia of pregnancy on the island of Montserrat in 1980, 1985, and 1990. This involved examination of clinic and hospital records for over 90% of all women giving birth on Montserrat in 1980 and 1985, as well as 80% of those giving birth in 1990. This examination showed a dramatic reduction in the prevalence of anemia at the time of the first prenatal visit (a drop from 82% of the study women in 1980 to 23% in 1985 and 19% in 1990) and also a marked drop at three days postpartum (from 91% in 1980 to 41% in 1985 and 39% in 1990). Logistic regression analyses indicated that after controlling for three possible confounding factors (maternal age, parity, and weeks of gestation at first prenatal visit) the difference between the risk of developing anemia during pregnancy in 1980 as compared to 1985 or 1990 was still highly significant. The reasons for the observed drop in anemia's prevalence during the survey period are not entirely clear, partly because of the retrospective nature of the study. However, better nutrition resulting from improvement in the standard of living on Montserrat during the survey period could have been important, as could changes in health education and food supplementation activities.

Two cases of severe head-banging parasomnias in peripubertal males resulting from otitis media in toddlerhood.

The author presents two case reports of peripubertal boys with severe and chronic head-banging parasomnias, or rhythmic movement disorders (RMDs), which started de novo whilst they were suffering from recurrent and severe otitis media in toddlerhood. Treatment consisting of straightforward behaviour modification techniques and advice concerning healthy sleeping habits proved highly successful. It is proposed that these late-onset or 'acquired' forms of RMD might be distinct from those which continue from infancy which have a stronger developmental aetiology.

Antidepressant prescription by British child psychiatrists: practice and safety issues.

OBJECTIVES: To evaluate the pattern of prescribing antidepressant (AD) drugs by British child psychiatrists with particular emphasis on the impact of newer-type (heterocyclic and selective serotonin reuptake inhibitor) agents on this practice and to assess the safety of AD use for children in terms of clinicians' reports of adverse effects. METHOD: A short postal survey asking specific questions about these aspects of their clinical practice was sent to 350 British child psychiatrists. RESULTS: The response rate was 71%. A clear majority of the 238 respondents (85%) who provided analyzable reports had prescribed ADs, the most popular of these being amitriptyline and imipramine, although nearly one third of prescribers also used newer agents occasionally and the selective serotonin reuptake inhibitors specifically, very rarely indeed. British child psychiatrists issued only one or two new prescriptions for AD medication per year. ADs were being used for a wide range of child and adolescent psychiatric disorders beyond the product data sheet-recommended indications of "depression" and "nocturnal enuresis." High rates of mostly mild adverse effects were reported in children treated with older-type ADs; however, the use of newer ADs did not appear to have influenced this picture when the reports of prescribers of only older ADs were compared with reports of those who also prescribed newer agents. CONCLUSIONS: Despite a willingness to use this form of treatment, British child psychiatrists tend to use it very sparingly compared to practices revealed in American studies. The preferential and infrequent use of older AD agents may account for the high rates of adverse effects reported. These practices do not allow clinicians to become familiar with, and thus more comfortable about, using newer agents.

Childhood sexual experiences with adults: adult male psychiatric patients and general practice attenders.

BACKGROUND: Sexual abuse of male children is now believed to be common, and there may be links to adult psychiatric disorders. METHOD: Recollections of sexual experiences with adults in childhood were studied systematically in 115 men attending general practice surgeries and 100 male psychiatric patients. RESULTS: The latter reported more frequent and more serious events before the age of 13 than the general practice attenders. No significant difference was detected for events between the ages of 13 and 15. CONCLUSIONS: Childhood sexual abuse before the age of 13 may be associated with later psychiatric disorders, although the nature of the association remains uncertain. The possible significance of such experiences should be considered when assessing men with mental disorders.

Analysis of a tension/compression skeletal system: possible strain-specific differences in the hierarchical organization of bone.

BACKGROUND: Examination of a simple skeletal cantilevered beam-like bone (artiodactyl calcaneus) suggests that regional differences in strain magnitude and mode (tension vs. compression) reflect regional adaptation in the structural/material organization of bone. The artiodactyl (e.g., sheep and deer) calcaneus has a predominant loading condition typified by the unambiguous presence of prevailing compressive and tensile strains on opposite cortices. Bone habitually loaded in bending may accommodate regional disparities in loading conditions through modifications of various aspects of its organization. These include overall bone build (gross size and shape), cross-sectional shape, cortical thickness, and mineral content. METHODS & RESULTS: Cross-sections taken along the calcaneal body exhibited cranial-caudal elongation with the compression (cranial) cortex thicker than the tension cortex (P < 0.01). Mineral content (ash fraction) was significantly greater in the compression cortex (P < 0.01), averaging 6.6% greater than in the tension cortex. Strong positive correlations were found between mineral content and section location in both the tension (r2 = 0.955) and compression (r2 = 0.812) cortices. These correlations may reflect functional adaptations to the linear increases in stress that are known to occur in the distal-to-proximal direction in simple, unidirectionally loaded cantilevered beams. According to engineering principles, the roughly triangular transverse cross-sectional geometries and thicker compression cortex are features consistent with a short cantilevered structure designed to resist unidirectional bending. CONCLUSIONS: Known differences in mechanical properties of bone in tension vs. compression suggest that these regional differences in cortical thickness and mineralization may be related to differences in strain mode. These structural/material dissimilarities, however, may be related to regional variations in strain magnitude, since bending and axially directed stresses in a simple cantilevered structure produce greater strain magnitudes in the compression domain. It is possible that the superimposed habitual strain magnitudes enhance strain-mode-specific adaptive responses. We hypothesize that these structural/material differences reflect the capacity of bone to process local information and produce a regionally heterogeneous organization that is appropriate for prevailing loading conditions.

Polydipsia amongst adults with a learning disability in an institution.

A hospital-based adult learning disabled population (n = 371) was screened for polydipsia with the help of a purpose-designed questionnaire. Polydipsia was defined as excessive drinking of more than 3 l of non-alcoholic fluid over a 24-h period. Altogether, 23 (6.2%) subjects were found to have polydipsia. The polydipsic group was compared with the whole hospital population on variables such as age and IQ distribution. A matched group of 23 individuals without a history of polydipsia was drawn from the same hospital population. The polydipsic and the matched group were compared using various biochemical and psychological measures. Thirty-five per cent of polydipsic patients, compared to 13% of the matched group, showed evidence of compensated hyponatraemia. This difference was not significant. There was no significant difference between the polydipsic and the matched group in the frequency of psychiatric illness, behavioural problems or autism. There also was no significant difference in the IQ levels of the polydipsic patients and the total hospital population. Polydipsia in this population is largely seen as part of an abnormal behavioural repertoire without any evidence of possible organic cause, except unidentified diabetes mellitus. Klein Levin syndrome and pica were represented in the polydipsic group, but not amongst the matched group.

Mammalian locomotor-respiratory integration: implications for diaphragmatic and pulmonary design.

Diaphragmatic function and intrapulmonary respiratory flow in running mammals were found to differ substantially from the corresponding conditions known in resting mammals. In trotting dogs, orbital oscillations of the diaphragm were driven by inertial displacements of the viscera induced by locomotion. In turn, oscillations of the visceral mass drove pulmonary ventilation independent of diaphragmatic contractions, which primarily served to modulate visceral kinetics. Visceral displacements and loading of the anterior chest wall by the forelimbs are among the factors that contribute to an asynchronous ventilation of the lungs and interlobar gas recycling. Basic features of mammalian respiratory design, including the structure of the diaphragm and lobation of the lungs, appear to reflect the mechanical requirements of locomotor-respiratory integration.
