X-linked mental retardation, macro-orchidism, and the Xq27 fragile site.

Twenty-three families with X-linked mental retardation were examined for the presence of a fragil site on the long arm of the X chromosome (Xq27 fra). Specific culture media were necessary to demonstrate this site. In only seven of the families was the Xq fragile site observed; in these, all of the affected males had both the fragile X and macro-orchidism. Macro-orchidism was not observed in the remaining 16 families. In the families with Xq27 fra segregating the fraes. This correlated with the age of the carrier. The 25 affected males with macro-orchidism and Xq27 fra had some minor clinical features in common: there was an increase in birth weight, high forehead, prognathism, pale irides, big ears, and an increased head circumference in infancy and childhood which did not persist into adult life. The majority of the affected individuals were moderately retarded.

B-mode echoencephalography in the normal and high risk infant.

Commercially available high resolution, contact, gray scale imaging systems can now dependably visualize the normal and abnormal ventricular system as well as some other intracranial structures in all newborns. On 25 normal infants and 41 high risk infants, 135 B-mode echoencephalograms were performed. The technique for obtaining these scans is described. The normal lateral ventricle at the midbody in term infants is 0.9--1.3 cm wide (mean, 1.1 cm). Normal ratio of lateral ventricle to hemisphere is 28% (range, 24%--30%). High risk premature infants have a ratio of 31% (range, 24%--34%). The demonstration of hydrocephalus and cystic intracranial masses is reliable and the correlation with computed tomography is excellent. Postoperative or high risk infants can be repeatedly evaluated without radiation, at a lower cost, and more rapidly with ultrasound than with computed tomography. Ventricular size can be closely monitored and shunt failure detected at any early stage.

Problems in the care of the infant diabetic patient.

The unique problems of three infants who developed diabetes mellitus at 13 months of age or younger are discussed. These problems include: the administration of small doses of insulin; the difficulty in attaining control; and the evaluation of urinary sugar content. Suggestions for care are made.

Carcinoembryonic antigen in renal allograft recipients and immunosuppressed renal patients.

Carcinoembryonic antigen (CEA) was estimated in plasma from 70 patients with a renal transplant, 105 patients with glomerulonephritis who had received immunosuppressive therapy, and 124 healthy controls. There were raised levels in 30% of those with a renal transplant, 10% of those with glomerulonephritis and 2% of controls, and levels were higher in current smokers. CEA levels did not correlate with pre-transplant dialysis time nor with serum creatinine levels, but tended to fall with increasing time after transplantation, especially in non-smokers. CEA levels did not correlate with prednisolone dosage nor with number of rejection episodes, after allowing for time after transplantation and smoking habit. Nine of 70 patients with a renal transplant and three of 105 with glomerulonephritis had cancer, of skin in seven, cervix uteri in four, and colon in one. CEA was raised in all four transplant recipients with a visceral cancer (cervix three and colon one), but in none of the five with cutaneous cancer. Raised CEA levels occurring late after a renal allograft should prompt a careful search for visceral cancer.
