Previously unrecognized congenital progeroid disorder

We report on a 5-year-old girl with a progeroid disorder and compare her to a previously reported woman now in her forties, whom she resembles to a striking degree. Common manifestations include pre- and post-natal growth retardation, markedly diminished subcutaneous fat, wrinkled skin, abnormally scant hair growth, hypoplastic distal phalanges with hypoplastic nails, umbilical hernia, large open anterior fontanelle, and normal cognitive and motor development. Both patients have had a prematurely aged appearance since birth. These 2 patients appear so different from previously reported patients with progeroid disorders that they may represent a separate entity.

Neonatal progeroid syndrome: more than one disease?

We report on an infant with the neonatal progeroid syndrome whose clinical course and autopsy findings indicate that this may be a heterogeneous phenotype. The infant had intrauterine growth retardation, absence of subcutaneous fat, and a wizened, aged face, all apparently characteristic of the condition, but also had congenital heart defects and urinary reflux not reported in previous cases. An elevated maternal serum alpha fetoprotein was noted at 16 weeks of gestation and late-onset growth retardation appeared after 31 weeks. Autopsy findings showed normal cerebral myelination, in contrast to findings of sudanophilic leukodystrophy in the one patient with the syndrome previously examined at autopsy. These findings suggest that the neonatal progeroid syndrome may be a phenotype and have more than one cause.

Congenital coronary artery obstruction associated with aortic anomalies in children: report of two cases

Coronary arterial obstruction associated with congenital aortic valve disease is rare in children. We studied two children with aortic valve disease and symptoms of coronary insufficiency. Cineangiography revealed localized obstruction of the proximal left coronary artery. In one patient, a membrane-like structure partially covered the left sinus of Valsalva, almost isolating the ostium of the left coronary artery; the other patient had severe stenosis of the proximal left coronary artery and a congenitally hypoplastic left coronary cusp. Surgical repair was successful in both cases. Symptoms of myocardial ischemia in children with aortic valve disease should be investigated promptly to exclude obstruction of the coronary arteries.

An unidentified neonatal progeroid syndrome: follow-up report

Two male infants with a pseudo-hydrocephalic progeroid syndrome with natal teeth are compared with two very similar female cases reported in the literature and interpreted as congenital progeria. All these cases may represent a separate entity, a previously unrecognized genetic progeroid syndrome.
