Abstract

I conducted a retrospective study based on record reviews of 50,892 infants born at the Foothills Provincial Hospital, Calgary, Alberta, Canada, from 1967 to 1984 to determine the incidence and possible causes of natal teeth. Fifteen infants were affected, for an incidence rate of one in 3,392 births. The affected teeth were the lower central incisors. The condition was more common in female infants. Two of the affected patients were twins. One patient each had Ellis-van Creveld syndrome, Pierre Robin syndrome, adrenogenital syndrome, cleft palate, and rickets. One mother each had pernicious anemia, vaginal infection, and diabetes mellitus.

[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.
