16q21 is critical for 16q deletion syndrome.

A 1-year-old girl with an interstitial deletion of the long arm of chromosome 16 is reported. She was characterized by a distinct craniofacial dysmorphism, meningoencephalocele, mild hydrocephalus, short neck, broad great toes and abnormally positioned toes. High resolution GTG and RBG banding analyses revealed a karyotype: 46,XX,del(16) (q13q22) de novo. An analysis of the smallest region of overlap revealed that the critical band region for 16q deletion syndrome is 16q21.

A new recognisable syndrome in three sibs with congenital heart disease, round face with depressed nasal bridge, short stature, and developmental retardation.

We report three sibs with congenital heart disease, round face with depressed nasal bridge, small mouth, short stature, developmental retardation, relatively dark skin, and high axial triradius. The chromosomes of the three patients were normal and the parents were unrelated, healthy, and of normal intelligence. The mother denied infections, drinking, drug intake, or exposure to known teratogenic agents during each pregnancy.

Chronopharmacological study of sodium valproate in mice: dose-concentration-response relationship.

Effects of the time-of-day of drug administration on the pharmacokinetics electroshock seizure (ES) threshold and acute toxicity were investigated in mice with sodium valproate (VPA). ICR male mice, housed under a light-dark (12:12) cycle, were orally administered 600 mg/kg VPA for anticonvulsant effect studies and administered 1500 mg/kg VPA for acute toxicity studies. A significant circadian rhythm was demonstrated for the ES threshold at 30 min after VPA administration, with the highest value in the light phase and the lowest in the dark phase, although no rhythm was shown in the nondrugged state. A significant circadian rhythm was also shown for plasma and brain VPA concentrations. This finding nicely corresponded to the circadian rhythm in the ES threshold. The positive relationship between the brain VPA concentration and the ES threshold was not different between the light phase and the dark phase. There was also a significant circadian rhythm in the acute toxicity induced by VPA, with the highest mortality in the light phase and the lowest in the dark phase. The results suggest the importance of time in the circadian stage at which VPA is administered in the experimental studies in mice and the significance of circadian rhythm in VPA kinetics in relation to the rhythm of ES threshold.

Association of tetra-amelia, ectodermal dysplasia, hypoplastic lacrimal ducts and sacs opening towards the exterior, peculiar face, and developmental retardation.

A male child with tetra-amelia, hypotrichosis, upward slanting palpebral fissures, lack of lacrimal openings, hypoplastic lacrimal ducts and sacs opening towards the exterior, prominent and bulbous nose, large downturned mouth, high narrow palate, bilateral preauricular pits, sacral dimple, bilateral undescended testes, and developmental retardation is reported. The parents were second cousins. His karyotype on cultured blood lymphocytes was normal. Since the next fetus conceived by the mother was found on prenatal ultrasonography to have no limbs, abortion was induced. The face of the abortus closely resembled that of the proband. It is postulated that this malformation syndrome was due to the homozygous state of a rare autosomal recessive mutation.

Kabuki make-up syndrome (Niikawa-Kuroki syndrome) associated with congenital heart disease.

Kabuki make-up syndrome has been reported mainly among Japanese, so far occurring in more than 20 cases. Among these, however, only one case associated with congenital heart defect has been reported. We have treated three patients with this syndrome and of these two had congenital heart disease. We suggest the possibility that the association of congenital heart disease with Kabuki make-up syndrome may not be fortuitous.

Association of ectodermal dysplasia, ectrodactyly, and macular dystrophy: the EEM syndrome.

We report five patients with ectodermal dysplasia, ectrodactyly associated with syndactyly or cleft hand or both, and, in addition, macular dystrophy which was presumed to be progressive, in an isolated population on a remote island in Japan. The heredity of this syndrome was thought to be autosomal recessive. Three cases have been reported so far with a combination of the same abnormalities. The parents in these cases were consanguineous.

Distal symphalangism associated with camptodactyly.

A Japanese family in which four patients in three generations had distal symphalangism associated with camptodactyly is reported. All of these patients had extension limitation of the proximal interphalangeal joints of the toes of both feet. Radiographs of the hands and feet, undertaken in three cases, showed no bone fusion of the distal and proximal interphalangeal joints. This malformation is caused by an autosomal dominant gene. To our knowledge, no previous case of distal symphalangism with extension limitation of the proximal interphalangeal joints has been reported.

Incontinentia pigmenti achromians as part of a neurocutaneous syndrome: a case report.

A case of incontinentia pigmenti achromians associated with mental retardation, epilepsy, short stature and ocular anomalies was reported. A study of this case together with a review of the 38 cases in the literature revealed that this entity has been associated with central nervous system involvements at a high frequency. It is necessary, therefore, to consider incontinentia pigmenti achromians as a neurocutaneous syndrome from the viewpoint of pediatric neurology.
