Familial gynecomastia without hypogonadism.

A family, six members of which had gynecomastia without hypogonadism, is presented. Endocrine studies failed to show the specific nature of breast enlargement in the patients. Chromosomal studies using peripheral leukocytes resulted in normal findings. In one of the patients, chromosomal studies were done using breast tissue and fascia, and again no abnormalities could be detected. The mode of inheritance may be autosoma dominant with sex limitations; however, X-linked inheritance cannot be ruled out.

Down syndrome due to 21;21 translocation in a male twin.

A spontaneous 21;21 translocation resulting in features consistent with Down syndrome is reported in the first born of male fraternal twins. No history of twinning or chromosomal abnormalities in the family was noted. Any association between dizygous twinning and Down syndrome due to de novo translocation remains speculative until a sufficient pool of published data is available from study of such families.

alpha-Thalassemia and beta-thalassemia in a Turkish family.

A Turkish family is described in which three children have a clinical picture similar to that of thalassemia major, with typical red cell morphology and indices, and with about 10% Hb Bart's but without measurable amounts of Hb H. Hematological evaluation of six members of this family that included in vitro hemoglobin synthesis suggests that beta-(or delta beta-) thalassemia, beta-silent thalassemia, and mild and severe alpha-thalassemia genes are present in different combinations. The data indicate that beta/alpha chain ratios in patients with more than one type of thalassemia should be evaluated in relationship to values obtained for several relatives even though some of the thalassemia determinants may be silent in the parents.

The Stickler syndrome (hereditary arthro-ophthalmopathy).

Three patients with Stickler syndrome are reported. Two of the patients were found among the 26 children attending a special pre-school for the visually impaired. One of the patients had bilateral choanal atresia which may represent an extreme example of the mid-facial hypoplasia commonly seen in these patients. It appears that Stickler syndrome may not be as rare as previously thought.

The radial dysplasia/imperforate anus/vertebral anomalies syndrome (the VATER association): Developmental aspects and eye findings.

The developmental evaluations of four children of different age groups with radial dysplasia/imperforate anus/vertebral anomalies syndrome are presented. These show that although the gross motor behavior is significantly delayed, intelligence, language, and social development are within normal range. Therefore, the patients with this syndrome merit every effort toward rehabilitation. Three of the patients discussed have ophthalmological abnormalities, in addition to their major malformations. It may be that congenital eye defects are another component of this syndrome of morphogenesis.

Chromosome variants in children with psychiatric disorders.

The authors studied the frequency of chromosome variants in 48 hospitalized children with psychiatric diagnoses (study group) in comparison with 10 hospitalized children with nonpsychiatric diagnoses (control group) and the results of three surveys of newborn children. They found that the frequency of variants in their study group was elevated in comparison with their control group and with the newborn surveys.

Aspects of pre-eclamptic toxaemia of pregnancy, consanguinity, twinning in Ankara.

It appears that women classed as having pre-eclamptic toxaemia are less frequently consanguineous with their husbands than all other mothers and in particular those mothers classed as having pregnancies complicated by chronic hypertensive disease. Search revealed no evidence for possible biases which could have stimulated such findings. Further evidence is advanced suggesting that, though pre-eclamptic toxaemia is more common in all types of twin pregnancies than in single births, it is more common where the twins are dizygous than where they are monozygous. It is pointed out that both these findings would be expected if there was a contribution to the aetiology of pre-eclamptic toxaemia by maternal/fetal immunological incompatibility. However, if such a mechanism exists it is not always determined at the same gene locus.
