Sixty-six schoolchildren aged 6 to 11 attending community schools suffered from various types of psychophysical infantilism and encephalopathic forms (in the cerebrasthenia and psycho-organic syndrome background) of mental retardation. The decompensation of the residual organic cerebral insufficiency with enhancement of neurosis-like and cerebrasthenic disorders resulting from increased mental load was the first stage of these children disadaptation to the school demands. At the 2nd stage, as the self-esteem lowered and negative attitude of other schoolchildren arose, the neurotic disorders emerged alongside with prevalent depressive reactions and fear of getting bad marks and being an object of ridicule at school. Children with lesser degrees of intellectual and encephalopathic disorders were better adapted to school environment.

We describe a family in which two adult sibs presented with a history of congenital nonprogressive myopathy, severe mental retardation and evidence of mild generalized weakness, short stature, musculoskeletal deformities, facial anomalies, sexual infantilism, and radiologic evidence of pituitary hypoplasia. The parents were first cousins. An excess of other, apparently unrelated, genetic conditions were present in other family members. Results of histochemical and electron microscopy studies of muscle biopsies from both affected individuals were compatible with multicore disease. This newly described syndrome likely is an autosomal recessive trait and appears to be the first reported association of multicore disease with mental retardation.

Eleven patients, 10 male, with classic hypertrophic obstructive cardiomyopathy and lentiginosis are described. Physical examination showed differences from the few previously reported cases in that (1) this condition was not confined to children; (2) mental retardation, sensorineural deafness and gonadal and somatic infantilism were either rare or absent; and (3) detailed family studies provided no evidence that this condition was inherited. Nine patients underwent cardiac catheterization and left ventricular angiography; all had left ventricular outflow obstruction and three had concomitant right ventricular outflow obstruction with a pressure gradient in excess of 100 mm Hg. Ten of the 11 patients were severely symptomatic, and 7, each with a left ventricular pressure gradient of more than 70 mm Hg, underwent successful septal myotomy/myectomy that resulted in marked symptomatic improvement that was maintained after long-term follow-up.

The clinical classification of mental retardation is reported. Three main clinical groups were screened: 1) mental retardation, due to the immaturity of the emotional-volitional sphere (different forms of mental infantilism); 2) mental retardation due to disturbances in the cognitive sphere (in stable neurodynamical and encephalopathic disturbances, deficiency in the higher cortical and subcortical functions; in disturbed regulation of cognitive activity); 3) general mental retardation, due to a combination of a disturbed cognitive sphere with organic infantilism. The paper concerns differential criteria for oligophrenia. It is recommended that children with stable retardation of the cognitive sphere be taught in special schools.

Biemond syndrome type 2 (BS2) is classically regarded as a recessively inherited condition (MIM 210350) comprising mental retardation, coloboma, obesity, polydactyly, hypogonadism, hydrocephalus, and facial dysostosis. Clinically, the disorder is closely related to Bardet-Biedl syndrome. Few cases have been reported, most of them before 1970. We present clinical data on three mentally retarded sporadic cases with coloboma, obesity, and hypogenitalism (in two of them), fitting as first glance a diagnosis of BS2. A review documents striking clinical variability among the patients said to have BS2. We propose a new nosology of those cases and delineate several new clinical forms. Purported BS2 cases may be divided into: (1) Bardet-Biedl syndrome with fortuitous coloboma or aniridia, (2) BS2 sensu stricto, a recessively inherited syndrome of sexual infantilism, short stature, coloboma, and preaxial polydactyly without obesity, only known from the original report, (3) a "new" dominantly inherited form of colobomatous microphthalmia occasionally associated with obesity, hypogonadism, and mental retardation, to which our observations belong. (4) cytogenetically proven Rubinstein-Taybi syndrome (one case), (5) an unclassifiable, early lethal familial syndrome resembling Buntinx-Majewski syndrome, and (6) a "new" coloboma-zygodactyly-clefting syndrome. The latter two syndromes may result from chromosomal anomaly.

Reduction of intelligence should be differentiated from interference with the use of intelligence by such non-intellective factors as partial deafness and emotional disturbance. The parents of a retarded child want an assessment, a prediction of the eventual achievement level, and a causal explanation if possible. There are varying degrees of knowledge of causation, from recognition of reduced intelligence only, to an understanding of the mechanism of causation in considerable detail from primary cause to ultimate consequence, as in phenylketonuria or isoimmunization. A diagnosis should be as complete as possible, using available modern techniques of investigation, such as chromatography and cytogenetic studies.AMONG THE RECENTLY DESCRIBED SYNDROMES ASSOCIATED WITH MENTAL RETARDATION ARE: (1) spastic paralysis and congenital ichthyosis; (2) Rud's syndrome; (3) deaf-mutism, infantilism, ataxia and a disturbance of hormone metabolism; and (5) sex-linked deaf-mutism.
