Abstract

From the literature we found reports of 105 patients whom we judged had a triangular deformity of one of the bones of the hand or foot. We found 49 patients of our own with 84 delta-shaped phalanges limited strictly to the hand. This represents an incidence of 3.5% of our congenital abnormalities of the upper extremity. The deformity is associated with many abnormalities: syndactyly, polydactyly, symphalangism, triphalangeal thumb, cleft hand, and hypoplastic hand are the most frequent Triangular deformity of the bone of the index finger usually is associated with Apert's syndrome. Triangular deformity of the proximal phalanx of the ring finger often is found with central polydactyly. Our average follow-up time on these 49 patients was 14 years, giving us a chance to establish some guidelines and general rules about the natural history and treatment of the delta bone.

[Lissencephalia syndromes].

Lissencephaly is in most cases a genetic anomaly of the brain development with agyria and/or pachygyria. It causes severe psychomotor retardation and epilepsy, which is often resistant to therapy. Some patients with type-I lissencephaly show cranial and facial dysmorphism and a deletion of chromosome 17p13.3 (Miller-Dieker syndrome). The isolated lissencephaly sequence occurs without these features. Patients with type-II lissencephaly present additional malformations of the posterior fossa and of the eyes (Walker-Warburg syndrome) and in some cases muscular dystrophy (cerebro-oculomuscular syndrome). Lissencephaly can be suspected with a high probability by its typical EEG. It is proved by imaging techniques. Therapeutic success is limited, the life expectancy is strongly reduced.

Williams syndrome in adults.

There are few published reports of adults with Williams syndrome (WS). We have evaluated ten adult WS patients. The patients in our study were very variable in clinical presentation, ranging from severely affected patients with complicated medical histories to mildly affected patients who are generally in good health. Cardiovascular anomalies and hypertension were frequent. Supravalvular aortic stenosis was seen in four patients, mitral valve prolapse in three, bicuspid aortic valve in one, valvular aortic stenosis in one, and pulmonary stenosis with right ventricular hypertrophy in one. Typical facial features included stellate irides, prominent cheeks, full lips, and micrognathia. Mental retardation was seen in all patients. Verbal skills were better developed than motor skills. All patients in our study lead active lives, and most are involved in sports. Some hold supervised jobs. Eight of our patients live with their parents and two in group homes. Independent living is restricted by their mental and adaptive limitations.
