Although the FDA recommends imipramine hydrochloride (IMI) only for temporary relief of symptoms of enuresis nocturna (EN), the drug has been applied to a number of other pediatric situations, including the Hyperkinetic Syndrome (HS), childhood depression, somnambulism and pavor nocturnus, school phobia, petit mal epilepsy, allergies, autism, encorpresis and head-banging. We have reviewed the literature, with particular attention to the pharmacokinetics of IMI in children, and its putative mechanisms of action. The drug probably works through a number of different actions, and the futher delineation of these will be of considerable heuristic value. We review the toxic effects of IMI treatment and IMI poisoning in children, and the pediatric literature concerning other antidepressant drugs and lithium carbonate (Li).

Recent twin and family studies have demonstrated a genetic factor in Gilles de la Tourette syndrome, some cases of infantile autism, enuresis, specific reading disability, sleepwalking, night terrors, common fears and anxiety. Family studies have been used to elucidate the nosological relationship of psychiatric disorders; e.g. anorexia nervosa (to affective disorder), Gilles de la Tourette syndrome, and sleeptalking. Advances in biochemical genetics and in enzyme polymorphisms suggest that there are wide individual variations in the adverse effects of drugs and that dosage should be tailored to the individual patient. Recently molecular genetic methods have been introduced to psychiatry, but a major breakthrough in this field appears to be still years away.

A comprehensive search and review of literature, documents, publications and other material written since 1970, relevant to American Indian mental health research, was completed in order to generate a list of research and of training needs. A content analysis of this literature enabled a synthesis which describes important biopsychosocial issues faced by American Indian communities, gaps in past and current research efforts, specific problems in past research, and recommendations in each of these areas with regards to future research possibilities and needs. The portion of the analysis presented in this paper deals with American Indian infants, preschoolers, children and adolescents. In order of presentation, the specific issue domains dealt with include: otitis media, fetal alcohol syndrome, abuse and neglect, failure-to-thrive/autism/enuresis, which are examined together (early development) in terms of research gaps; and neurosensory disorders/developmental disabilities/handicapping conditions/school-related problems, foster care and adoption, self-concept/identity, conduct disorders/delinquency, drug and alcohol use, and suicide and depression, which are examined (school-age children and adolescents) in relation to research gaps and needs.

Autistic children undergoing therapeutic programs, which adopt in our service (USL 3 CT) different theoretical approaches, sometimes show a marked reduction in motor activities, a lowering of tone of voice, physical expression of sadness. We observe that animation is absent in the scene they may draw and colours are no longer used in their drawings. Sleep disturbance may appear or reappearance of enuresis. Many authors consider these symptoms as signs of depression. These changes, even though they create new problems in therapeutic management, are, in our opinion, a very important index of the unblocking of autistic withdrawal and beginning of development of those emotional, relational and cognitive components which seem to be frozen in autistic children and inhibit the birth of the mind, according to the U. Frith Theory. We report in this paper the psychoanalytic, cognitive, systemic, biological viewpoint on the occurrence of depression in infantile autism. We submit three cases of patients being treated in our service with the cognitive-behavioural oriented educational program and pharmacological therapy and discuss the multidimensional approach. The temporary occurrence of depression symptoms may be an index of a change within the resisting autistic balance, which may have a biological basis, but indicates the disorganization of the autistic child's mind in view of further development.

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.

In patients with Rett syndrome (RS), a peculiar type of disturbance in phasic chin muscle activity during rapid-eye-movement sleep (REMS) (e.g. an elevation of phasic inhibition index (PII) without an affection of tonic inhibition index (TII)) has been reported. The similar disturbance in REMS was reported not only in child patients with infantile spasms, severe myoclonic epilepsy in infancy (SMEI), severe nocturnal enuresis, and autism but also in adult patients with Parkinson's disease (PD). Except for SMEI and PD, patients with the other four clinical entities including RS could express autistic tendency. Since the responsible lesion for the occurrence of an elevation of PII with a normal TII value is likely to be in the pontine tegmentum, this subcortical structure is hypothesized to be involved in the appearance of autistic tendency.

Autism is a developmental disability characterized by severe deficits in social interaction and communication, and the presence of repetitive-ritualistic behaviors. Sleep problems are frequently reported by parents of children with autism with prevalence estimates of 44-83% for sleep disorders in this population. To better understand sleep in autism, we surveyed sleep problems in 210 children with autism using a Likert-based questionnaire for parent report. The most frequently reported sleep problems included difficulty in falling asleep, restless sleep, not falling asleep in own bed, and frequent wakenings. Least frequently reported sleep problems were sleep walking, morning headaches, crying during sleep, apnea, and nightmares. When surveys were divided into mental retardation (MR)/not MR categories, no significant differences were identified in frequencies of reported sleep problems except for waking at night which occurred much more frequently in the MR group. There was also no difference in sleep problems related to age of the child other than nocturnal enuresis. An association was noted between certain medical problems and sleep problems. Vision problems, upper respiratory problems, and runny nose were associated with decreased nighttime sleep. Vision problems, poor appetite, and poor growth were associated with increased nighttime waking. Poor appetite and poor growth were associated with decreased willingness to fall asleep. This study confirms a high prevalence of sleep problems reported by parents of children with autism and points to the need for more systematic research as an initial step in developing treatment strategies.

We describe our experience in using melatonin to treat insomnia, a common sleep concern, in children with autism spectrum disorders. One hundred seven children (2-18 years of age) with a confirmed diagnosis of autism spectrum disorders who received melatonin were identified by reviewing the electronic medical records of a single pediatrician. All parents were counseled on sleep hygiene techniques. Clinical response to melatonin, based on parental report, was categorized as (1) sleep no longer a concern, (2) improved sleep but continued parental concerns, (3) sleep continues to be a major concern, and (4) worsened sleep. The melatonin dose varied from 0.75 to 6 mg. After initiation of melatonin, parents of 27 children (25%) no longer reported sleep concerns at follow-up visits. Parents of 64 children (60%) reported improved sleep, although continued to have concerns regarding sleep. Parents of 14 children (13%) continued to report sleep problems as a major concern, with only 1 child having worse sleep after starting melatonin (1%), and 1 child having undetermined response (1%). Only 3 children had mild side-effects after starting melatonin, which included morning sleepiness and increased enuresis. There was no reported increase in seizures after starting melatonin in children with pre-existing epilepsy and no new-onset seizures. The majority of children were taking psychotropic medications. Melatonin appears to be a safe and well-tolerated treatment for insomnia in children with autism spectrum disorders. Controlled trials to determine efficacy appear warranted.
