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.

Two hundred and twenty-one disabled children from seven diagnostic groups have been examined with respect to height, weight and prevalence of four different feeding problems. Retarded growth and feeding problems were common in children with cerebral palsy, mental retardation, congenital heart disease and deaf-blindness, but rare in children with esophagus atresia, cystic fibrosis and epilepsy. Mean relative height and weight were significantly lower (p much less than 0.01) in children with mechanical feeding problems, such as impairment of self-feeding skills and oral-motor dysfunction, than in children without these problems, regardless of diagnostic group. Mean relative weight was also significantly lower in children with poor appetite than in children with good appetite. Feeding problems contribute to short stature and underweight in severely disabled children.

The clinical histories and treatment of the nine individuals with Down syndrome (DS) and major depression (MD) previously noted in a report on the psychopathology of a population of 164 adults with DS with and without health disorders from a Down Syndrome Clinic are presented (Myers & Pueschel, 1991). The clinical characteristics including DSM-III-R (1987) criteria of these 9 patients plus 13 individuals with DS and MD described in case reports in the literature are summarized. Depression is rarely verbalized and commonly appears as crying, depressed appearance, or mood lability. Vegetative symptoms of disinterest with severe withdrawal and mutism, psychomotor retardation, decreased appetite, weight loss, and insomnia are prominent. Verbal expression of preoccupations of suicide, death, self-depreciation, and guilt were infrequent and may either be not present or not reported due to mutism or moderate level of mental retardation (MR). Hallucinations were prominent. Family history of depression was infrequent. Psychological stressors were noted mostly in the study sample and not in the 13 from the literature. The pattern of vegetative symptomatology with few verbal complaints and prominent hallucinations may be related to moderate mental retardation in these groups with DS rather than specifically to DS.

Three Japanese patients with carbonic anhydrase II (CAII) deficiency from three families were described. The parents of one patient were unrelated, the parents of each of the other two patients were first cousins. All the patients had renal tubular acidosis, osteopetrosis, symmetrical cerebral calcification and mental retardation. They exhibited poor activity and poor appetite in the neonatal period, and then developed psychomotor retardation. Two of them were diagnosed as having osteopetrosis at 10 months and 36 years of age, respectively, and the other as having osteomalacia at 28 years of age. All patients had recurrent episodes of muscle weakness. The CAII enzyme activity and protein levels in red blood cells in each of the three patients were deficient. Their parents exhibited approximately 50% normal levels of CAII activity and protein. This is the first report of patients with CAII deficiency in the Japanese population.

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.
