A review is presented of the diagnosis and drug treatment of the more common psychiatric and developmental disorders in the pediatric population. Where applicable, DSM III (Diagnostic and Statistical Manual of Psychiatric Disorders, III) criteria are utilized to describe the behavioral syndromes. The indications for usage and appropriate dosages of antipsychotics, antidepressants, anxiolytics, stimulants, and lithium are described. Those disorders discussed are attention deficit disorder, conduct disorders, anxiety disorders, sleep disorders, schizophrenia, autism, Tourette's syndrome, mental retardation, depressive illness, manic depressive illness, eating disorders, and enuresis.

A yin-yang hypothesis is presented linking noradrenergic activity, thromboxane, melatonin, left hemisphere functioning, and cyclic AMP on the one hand, and dopamine, beta-endorphin, calcium, right hemisphere functioning, and cyclic GMP on the other. It is further suggested that there is a yoking of NA, TXA2, serotonin and melatonin in the left hemisphere, and a similar yoking of DA, BE, calcium and cGMP in the right. Evidence is presented to support the hypothesis that each element (NA, TXA2, etc.) on one side can modulate or balance a corresponding element (DA, BE, etc.) on the other. It is suggested that thromboxane is the key element in noradrenergic overactivity and that not taking this into consideration has confounded much prior research. This theory takes into account information processing models as well as pharmacological data and neurochemical theory on coupling of adenylate cyclase to its hormone receptors. Inhibiting noradrenergic overactivity can be obtained by inhibiting thromboxane and concomitantly activating opiate receptors. This protocol may have clinical utility in treating a wide range of disorders such as: anxiety, depression, schizophrenia, sleeplessness, withdrawal states, enuresis, Gilles de la Tourette syndrome, Parkinsonism, Alzheimers, dementia, anorexia, infant ruminations, essential tremor, spasticity of spinal cord injury, diarrhoea, ulcerative colitis, extrapyramidal symptoms, akathisia, neuroleptic malignant syndrome, attention deficit disorder, hyperhidrosis, and possibly AIDS.

A 22-year-old man was referred to us complaining of enuresis. The excretory urogram and cystogram were almost normal. Spina bifida was not present. The results of the urodynamic examination including uroflowmetry, cystometry, urethral pressure profile, electromyogram and sensory threshold of external urethral sphincter were within normal limits. Amitriptyline hydrochloride and flavoxate hydrochloride showed no effects. Because we found a positive spike wave on the electroencephalogram, the patient was referred to a psychopathologist, and was diagnosed as being in the early stage of schizophrenia. He complained of enuresis as his olfactive hallucination of urine. Psychopathological treatment for 1 year and 2 months resulted in disappearance of his complaining of enuresis.

Clozapine has been found to be superior to traditional neuroleptics in the treatment of refractory schizophrenia and is increasingly being used to treat schizophrenia, affective disorders, some neurological disorders, and aggression. For many patients, clozapine offers new hope for the successful pharmacological management of a disabling mental disorder. However, up to 17 percent of patients must discontinue treatment with clozapine because of adverse effects, which also limit the rate at which the dose can be increased and the maximum dose that can be tolerated. This article reviews strategies for minimizing and managing the adverse effects of clozapine, including agranulocytosis, seizures, sedation, delirium, obsessive-compulsive symptoms, hypotension, tachycardia, weight gain, sialorrhea, elevated liver enzymes, constipation, nausea, enuresis, fever, and neuromuscular effects. Incidence and morbidity are presented first. Then, the known or hypothesized pathophysiology of the adverse effects are described. Finally, nonpharmacological and pharmacological interventions are reviewed. Under-standing the incidence, pathophysiology, and treatments of adverse effects is essential for a positive therapeutic outcome when prescribing clozapine.

Family and adoption studies indicate that genetic factors play a role in the development of many psychiatric disorders. A variable number of possible interacting genes giving a predisposition to the diseases is likely. The genetic dissection has been hampered by genetic complexity as well as by difficulties in defining the phenotypes. Genetic mapping efforts using sib pairs, twins and individual large families have revealed preliminary or tentative evidence of susceptibility loci for a number of psychiatric disorders. Illnesses described in this article include the prion disease familial fatal insomnia (FFI), alcoholism, anorexia nervosa, autism, bipolar affective disorder, dyslexia, enuresis nocturna, epilepsia, obsessive-compulsive disorders (OCD), schizophrenia, and the dementias, Alzheimer's disease and frontal lobe dementia. The genes and proteins related to the newly discovered transmitter in the central nervous system, nitric oxide (NO), and its genes and proteins are also reviewed. The number of mapped human genes now exceeds 30,000 of the estimated total number of 60,000 to 100,000 genes. This rapid development will facilitate gene mapping and efforts to isolate and identify the genes responsible for symptom susceptibility in many of the aetiologically unclear psychiatric diseases with complex genetic origin.

The chromosome 22 workshop took place at the Sixth World Congress on Psychiatric Genetics from October 6th-10th, 1998 in Bonn, Germany. Aim of the workshop was to summarize the findings in psychiatric genetics on chromosome 22. Four reports concerning a susceptibility locus for schizophrenia and one report on bipolar disorder were given. A potential locus for nocturnal enuresis has been suggested to reside on chromosome 22.

This is a review of pharmacotherapy in children and adolescents with mental retardation from the perspective of DSM and ICD disorders. The existing research is reviewed in young people with mental retardation but, when data are lacking, we examined the literature from adults with mental retardation and from typically-developing children. The literature is discussed for each of the following disorders: ADHD, anxiety disorders, bipolar disorder, conduct disorder, depression, enuresis, schizophrenia, self injury, and tics and movement disorders. With the possible exception of ADHD, there is a woeful lack of empirical data on most of these disorders in young people with mental retardation. Clinicians will often be forced to extrapolate from data on adults having mental retardation and from typically-developing children. The best policy is probably to treat such patients cautiously, while gathering data on the effects of such therapy in the hopes of beginning a data base.

Mild personality problems have been described in patients with juvenile myoclonic epilepsy (JME), but clinical practice shows that JME can be diagnosed in patients with more or less severe psychiatric disorders (PD). The presence in JME patients of personality disorders has been described repeatedly, but never quantified. We thus decided to evaluate, using the DSM IV, the current prevalence and types of PD in a large series of consecutive, newly referred patients with JME. Among 170 consecutive JME cases referred to two departments of epileptology (Marseilles and Nice) between 1981 and 1998 (66 males, 104 females; aged 11.7-70; mean+/-SD 32.4+/-10.4 follow-up 12.7+/-10 [0.5-52]), we found 45 patients (26.5p.100) with PD. According to the DSM IV, they could be classified as severe mental retardation (main diagnosis) (one case); pervasive developmental disorders (2 cases); tic disorder (1 case); enuresis (1 case); psychotic disorders (5 cases, including schizophrenia paranoid type (1 case), disorganized type (1 case), delusional disorder (1 case), unspecified (2 cases)); depressive disorders (3 cases); generalized anxiety (6 cases); anorexia nervosa (2 cases); personality disorders (24 cases, including borderline personality (11 cases), dependent personality (5 cases), histrionic personality (2 cases), obsessive-compulsive personality (1 case), not specified (5 cases)). Sudden unexplained death occurred in 2 cases (borderline personality and pervasive developmental disorder not otherwise specified, respectively) and death due to pneumonia in 1 cases (anorexia). Although uncommonly severe cases of JME may have been selected in our referral centers, it appears that JME may be associated with PD. Comparatively mild personality disorders are the most common finding, and may be part of the clinical picture to some extent, while severe PD are less common, and probably coincidental. The presence of PD does not exclude the diagnosis of JME, and PD may represent a further challenge in the comprehensive care of these patients.

The meaning and relevance of the increased rates of neuromotoric deviation (ND) observed in patients with schizophrenia and their biological relatives remain unclear. ND could represent free-floating, independent characteristics of individuals in these families vs. signs of an increased risk for current or future mental disorder. The co-temporaneous relationship between ND and mental disorder at 6 years of age was investigated among 31 children with an increased risk for schizophrenia and similar psychoses, defined as having a mother with a history of schizophrenia or unspecified functional psychosis. As compared with high-risk cases with a low level of ND, the subgroup of 10 high-risk offspring showing notably increased rates of ND had significantly more frequent psychiatric diagnoses (typically language disorders and enuresis), poor functioning on global assessment, poor interpersonal competency and high anxiety proneness. Neuromotoric items representing "overflow" (e.g., choreatic movements, tremor) were significantly positively related to each of these mental characteristics. Among high-risk offspring, an increased rate of ND is very clearly associated with increased rates of current mental disorder, and might potentially identify a subgroup with an especially high risk for serious mental disorder in the future.
