An open trial of pharmacological treatment with fluoxetine, ranging from 20 mg every other day to 80 mg per day, led to a significant improvement in Clinical Global Impressions ratings of Clinical Severity in 15 of 23 subjects with autistic disorder and 10 of 16 subjects with mental retardation. Six of 23 patients with autistic disorder and 3 of 16 patients with mental retardation had side effects which significantly interfered with function, consisting predominantly of restlessness, hyperactivity, agitation, decreased appetite, or insomnia. Double-blind studies of the efficacy of pharmacological agents that potently inhibit 5-HT uptake in the treatment of mental retardation coexisting with Axis I psychiatric disorders (especially obsessive-compulsive disorder) and autistic disorder are warranted.

We often experience the case that is difficult to differentiate normal from abnormal myelinating process by CT scan, because the diagnosis of myelinating maturation of the infant during developmental process is confusing. We can understand maturation of myelination adding to the advancement of diagnostic resolution by MR imager. So we obtain more informations about the abnormality of myelination and development of the brain by MR imaging than CT scan. This study demonstrates the ability of MR imaging to show progression of myelination in 10 infants and children. We also reveals the patients with disorders of neuronal migration or myelination during developing process. MR scanning could be obtained by sedation using such as triclofos or chloral hydrate for infant and younger children. It was necessary to use diazepam or pentazocine intravenously for elder children with mental retardation or restlessness. MR scans were performed with Siemens MAGNETOM 1.5 Tesla. T 1-weighted spin echo image (TR 600/TE 15) and T 2-weighted image (TR 3000/TE 90) were obtained for all cases. The ten normal infants and children (7 boys, 3 girls) were aged from 1 month to 4 years. Maturation of white matter generally proceeded from posterior limb of internal capsule to middle cerebellar peduncle, cerebellar white matter, corpus callosum, anterior limb of internal capsule, occipital white matter, centrum semiovale, finally frontal white matter. Myelination was matured during the first two years by T 2-weighted images. Changes caused by brain myelination were seen earlier on T 1-weighted images (7 months after birth) than on T 2-weighted images (one year and 9 months after birth).(ABSTRACT TRUNCATED AT 250 WORDS)

In present-day African psychiatry, there is a sharp differentiation between serious mental illness, which requires medically orientated treatment and chemotherapy, and the more superficial disturbances of personality for which psychological, sociological and educational measures are indicated. With the severe shortage of Western psychiatrists who are prepared to undertake this work, it is providential that black traditional healers address themselves to the latter group of mental abnormalities with a measure of success comparable to psychotherapy in First-World practice. In the back wards of a mental hospital (run on First-World lines) and in outpatient clinics in periurban Durban townships, one meets a large number of patients with severe and chronic disease. All those conditions (mental retardation, organic brain syndromes, schizophrenia and affective disorders) with positive symptomatology (excitement, restlessness and aggression) are found to respond to neuroleptic drugs. Possible reasons why patients with negative symptoms (emotional withdrawal, poverty of ideas and speech), especially in schizophrenia, do not react, are discussed, and administrative and socio-economic implications are reviewed.

The development of a scale to assess drug and other treatment effects on severely mentally retarded individuals was described. In the first stage of the project, an initial scale encompassing a large number of behavior problems was used to rate 418 residents. The scale was then reduced to an intermediate version, and in the second stage, 509 moderately to profoundly retarded individuals were rated. Separate factor analyses of the data from the two samples resulted in a five-factor scale comprising 58 items. The factors of the Aberrant Behavior Checklist have been labeled as follows: (I) Irritability, Agitation, Crying; (II) Lethargy, Social Withdrawal; (III) Stereotypic Behavior; (IV) Hyperactivity, Noncompliance; and (V) Inappropriate Speech. Average subscale scores were presented for the instrument, and the results were compared with empirically derived rating scales of childhood psychopathology and with factor analytic work in the field of mental retardation.

The oculocerebrorenal syndrome (OCRS), Lowe's syndrome, is an X-linked, recessive disease characterized by mental retardation, congenital corneal abnormalities and cataracts, growth failure, rickets, osseous abnormalities, renal dysfunction with periodic acidosis, hypotonia, and areflexia. Ultrastructural studies of skin biopsy specimens in three individuals with the disorder (aged 17, 9, and 8 years) revealed cytoplasmic, membrane-bound, electron-lucent vacuoles and some electron-dense membranous inclusion bodies in fibroblasts and Schwann cells, as well as axonal degeneration and vascular changes. Computed tomographic scans evidenced brain atrophy. Urinary excretion of glycosaminoglycans (GAG) was four to five times greater than in normal controls. The predominant urinary GAG was a low-sulfated chondroitin-4-sulfate; chondroitin-6-sulfate and heparan sulfate excretion levels were normal. A tenfold increase in urinary GAG excretion was found in one patient with oculocerebrorenal syndrome during periods of behavioral agitation. These findings suggest that the clinical stigmata of oculocerebrorenal syndrome may be related to a defect in GAG metabolism.

The aim of this study was to evaluate the dental treatments under nitrous oxide-oxygen sedation carried out during 1 yr by the first 45 Swedish dentists trained at probationary courses in the use of the technique. Special emphasis was placed on evaluating the risk and incidence of side effects. Data from 1719 treatment sessions in 823 patients, mainly children, were analyzed. Standardized sedation technique was used and the maximum level of nitrous oxide administered was set at 60%. About 90% of the patients showed excellent or fair acceptance. Factors influencing the acceptance were the patient's age, history of psychiatric disorders, mental retardation and occurrence of side effects. In 4.5% of the treatment sessions the patient experienced side effects, e.g. restlessness, vomiting or nausea, during treatment and in 0.9% after the treatment session. The side effects were mainly mild. No correlation was found between side effects and the nitrous oxide concentration used, length of treatment, patient's age or health classification. It is concluded that nitrous oxide-oxygen sedation is an excellent and safe aid to dental care.

We contrasted a sample of children and adolescents with affective disorders and mental retardation with a comparison group on behavioral symptoms, associated diagnoses, and psychopharmacologic treatment. Fifty consecutive patients with both impaired intellectual functioning and at least one affective disorder admitted to a psychiatric inpatient unit for children and adolescents with developmental disabilities and psychiatric disorders were matched to a group of 50 inpatients without depression. Behavioral symptoms such as suicidal ideation or gestures, crying, irritability, sleep problems, agitation, mood lability, and social withdrawal/isolation occurred significantly more often in the affective group than in the comparison group. Aggression, however, was the most frequent behavior concern for both groups, whereas disruption/destruction was identified significantly more often in the comparison group. Regarding Axis I diagnoses, the comparison group was more often identified with externalizing disorders (ADHD, ODD), though there was a high rate of comorbidity in the affective disorder group. The behavioral symptoms used to diagnosis normally developing children and adolescents appear to be applied in making affective disorders diagnoses in this sample of children and adolescents with mental retardation.

Neuroleptic-induced akathisia is a relatively common side effect of neuroleptic medication, characterized by a subjective sense of restlessness and the inability to sit still. It has been associated with aggression, anxiety, sleep disturbance, and suicide among patients who have mental illness. These side effects are fairly well-researched in the psychiatric literature but rarely addressed in the mental retardation literature. The prevalence, types of akathisia, differential diagnosis, and treatment were reviewed and a relevant case report presented. The importance of the diagnosis and treatment of neuroleptic-induced akathisia in individuals with mental retardation was discussed.

Measurement methods from behavioral psychology were used to assess antiepileptic drug behavioral side effects in 5 individuals with mental retardation. When the suspected antiepileptic drug was altered, an 81% reduction of maladaptive behaviors occurred. Quality of life outcomes included successful community placement and termination of an aversive intervention procedure. Three cases demonstrated antiepileptic drug exacerbation of disruptive vocalizations, agitation, self-injurious behavior, and property destruction; 2 demonstrated improved aggression, but illustrated a common clinical problem. When seizure control must be maintained and a suspected antiepileptic drug cannot be reduced before a second antiepileptic drug with potential psychotropic properties is initiated, it was not possible to absolutely conclude that the first antiepileptic drug was responsible for the behavior problem. Overall, these measurement methods were instrumental in the systematic clinical evaluation of antiepileptic drug behavioral side effects in individuals unable to verbally communicate the presence of these side effects.

Thirty-two children with refractory partial epilepsy received open-label gabapentin as an additional medication to their antiepileptic drug regimen. Gabapentin was given in a dose ranging from 10 to 50 mg/kg per day (mean dose, 26.7 mg/kg daily). All patients had partial seizures with or without secondary generalization. Compared with baseline, 11 patients (34.4%) had a greater than 50% decrease in seizure frequency, and 4 (12.5%) had a 25% to 50% decrease in seizure frequency. Of the seven children who received the medication for 6 months or longer, two were seizure free and four were almost seizure free (having one seizure every few months). Mean gabapentin concentration was 4.8 micrograms/ml, and mean apparent clearance was 372 ml/kg per hour. The major reported side effects were behavioral. These consisted of hyperactivity, irritability, and agitation that occurred in patients with baseline mental retardation with attention deficit. We conclude that gabapentin can be a useful adjunctive medication in the treatment of refractory partial epilepsy in children.
