The Importance of Separation-Individuation Process in the Treatment Course of A Monozygotic Twin Pair Concordant for Anorexia Nervosa: A Case Report

Death in utero of one member of a monozygotic twin pair has been associated with vascular disruptive phenomena in the surviving twin. It has been hypothesized that this event initiates clot formation in the surviving twin with consequent necrosis of tissues distal to the occluded vessels. This case report describes onset in utero of multicystic encephalomalacia and microcephaly in a surviving twin whose brain appeared normal on ultrasound scanning before death of the cotwin at 21 weeks' gestation. The case provides further support for the hypothesized pathogenetic sequence and illustrates the importance of reviewing all prenatal ultrasound scans in infants with congenital microcephaly.

SUMMARYA case of one twin pair concordant or discordant as to a given disease is always very important for Clinical Genetics, especially when it is monozygotic. In Clinical Genetics, isolated pairs occur to the physician, and the diagnosis must therefore be based on intra-pair comparison. The statistical treatment of the case must consider the fact that a concordant monozygotic twin pair represents a statistical universe rather than a statistical unit. This entails taking into account many traits concerning the time of onset, the symptoms, development, result of treatment, etc. Suggestions are made for the statistical treatment of such cases.

Coloboma Of The Iris

This article discusses the major differences which can be fuond from time to time in homozygotic twins. In some instances there may be differences in manifestation, as in the case of a pair of monozygotic twins, aged 12, with concordant dysplasia of the hipjoint but with different radiological pictures. Differences may also be due to particular incidents during intrauterine life, alterations in growth resulting from hormonal disturbances etc. In some cases the cause of the differences is not known and, as an example, the author cites a monozygotic twin-pair aged 10, one member of which is much retarded in growth while the co-twin suffers from coloboma of the iris.
