Tandem dup (1p) within the short arm of chromosome 1 in a child with ambiguous genitalia and multiple congenital anomalies.

A newborn infant was found to have multiple congenital anomalies including bilateral cleft of lip and palate, intrauterine growth retardation, microcephaly, tetralogy of Fallot, ambiguous external genitalia, and presence of male and female internal genitalia. Chromosome analysis showed a tandem duplication of part of the short arm of chromosome 1, resulting in a dup(1p31----35). The karyotype designation is 46,XY,dir dup(pter----31::p35----p31::p31----qter). The exact nature of the chromosome anomaly was clarified with use of several banding methods.

Manifestations of pseudoxanthoma elasticum during pregnancy: a case report and review of the literature.

A 30-year-old white woman with pseudoxanthoma elasticum (PXE) was followed throughout her pregnancy with several fetal ultrasonographic examinations and other diagnostic studies; these showed normal development up to the 26th wk and then a marked deceleration of fetal growth. The ultrasonographic appearance of the placenta was abnormal at all times probably related to the microscopic changes. The baby, born at 36 wk, showed severe intrauterine growth retardation as a probable consequence of the abnormal placenta detected by ultrasound and corroborated at birth. The cotyledons were small and more numerous than normal. One third of the placenta was hypoplastic or atrophic, with focal calcification in septa, stroma, villi, and decidua, and increased deposition of fibrin around villi. The most striking change was the increased number of septa and the abnormal elastic tissue.

Fibrochondrogenesis: lethal, autosomal recessive chondrodysplasia with distinctive cartilage histopathology.

Fibrochondrogenesis is a rare, neonatally lethal rhizomelic chondrodysplasia distinguished from other forms of lethal dwarfism by broad long-bone metaphyses, pear-shaped vertebral bodies, and by microscopic changes of cartilage with unique interwoven fibrous septa and fibroblastic dysplasia of chondrocytes. We report the second and third well-documented cases of this apparently autosomal recessive disorder and discuss the differential diagnosis.

Geleophysic dysplasia.

On the basis of three affected sibs and one isolated case from the literature geleophysic dysplasia is defined as an acrofacial dysplasia with a peculiar, good-natured facial appearance, short hands and feet due to short, plump tubular bones, small stature, and progressive valvular cardiac disease. It seems to be a hereditary disorder of glycoprotein metabolism with autosomal recessive transmission.

Acrofacial dysplasia resembling geleophysic dysplasia.

We report on a 12-year-old girl with acrofacial dysplasia, growth retardation, joint contractures, mitral valve incompetence and focal hepatic storage of material reacting histochemically as glycoprotein. The patient's phenotype resembles that of patients with geleophysic dysplasia but differs with respect to facial appearance, milder changes of hand bones and normal capital femoral epiphyses. It is undecided if her disorder is part of a wider phenotypic spectrum of geleophysic dysplasia or a different entity.

Total lymphatic irradiation and bone marrow in human heart transplantation.

Six patients, aged 36 to 59 years, had heart transplants for terminal myocardial disease using total lymphatic irradiation (TLI) and donor bone marrow in addition to conventional therapy. All patients were poor candidates for transplantation because of marked pulmonary hypertension, unacceptable tissue matching, or age. Two patients are living and well more than four years after the transplants. Two patients died of infection at six and seven weeks with normal hearts. One patient, whose preoperative pulmonary hypertension was too great for an orthotopic heart transplant, died at 10 days after such a procedure. The other patient died of chronic rejection seven months postoperatively. Donor-specific tolerance developed in 2 patients. TLI and donor bone marrow can produce specific tolerance to donor antigens and allow easy control of rejection, but infection is still a major problem. We describe a new technique of administering TLI with early reduction of prednisone that may help this problem.

Apnea and sudden unexpected death in infants with achondroplasia.

Thirteen infants with achondroplasia and sudden unexpected death or unexplained apnea were discovered through nonsystematic retrospective case collection. Most were initially thought to have died from sudden infant death syndrome. However, historical and pathologic findings suggest that many of these infants had apnea and sudden unexpected death secondary to acute or chronic compression of the lower brainstem or cervical spinal cord. Infants with achondroplasia evidently are at considerably increased risk for such deaths between 1 month and 1 year of age. Appropriate intervention, given these previously unrecognized risks, may include cervical restraint, polysomnographic evaluation, and apnea monitoring.

Granulomatous coronary arteritis.

Pulseless disease, or Takayasu's arteritis, is usually found in the aorta and its major branches in young female patients. Involvement of the coronary arteries is extremely rare. Fewer than 25 cases have been reported. This report documents a case of a 71-year-old man who died of coronary insufficiency and myocardial infarction. The autopsy disclosed extensive granulomatous coronary arteritis.

Renal-nonresponsive, bone-responsive pseudohypoparathyroidism. A case with normal vitamin D metabolite levels and clinical features of rickets.

Clinical signs of rickets developed in a previously healthy 13-year-old girl with normal features. She had hypocalcemia, hyperphosphatemia, elevated alkaline phosphatase and parathyroid hormone levels, and normal vitamin D metabolite levels, with osteitis fibrosa cystica on bone biopsy specimen. Her renal function was normal. Treatment with 1 microgram of calcitriol each day resulted in symptomatic and clinical relief and improvement of the serum chemical values. This patient probably has pseudohypoparathyroidism type 1, with renal nonresponsiveness and bone responsiveness. This disorder has the clinical features of rickets, but represents hyperparathyroid bone disease.

Congenital heart anomalies in the trisomy 18 syndrome, with reference to congenital polyvalvular disease.

Congenital polyvalvular disease (CPVD) is seen in trisomy 18 and other aneuploidy syndromes. However, its extent and nature have not been studied. Gross pathologic and histologic aspects of the heart were studied in 15 autopsied cases of trisomy 18. All had CPVD; other congenital defects included membranous ventricular septal defect (87%), patent ductus arteriosus (73%), and high takeoff of the right coronary ostium (80%). With a scoring system, histologic findings of the valves of all trisomy 18 cases were compared with those of 30 normal hearts of comparable age in order to determine the degree of morphologic abnormality. This included the presence of blood cysts, derangement of the spongiosa and fibrosa, vascular degeneration of the spongiosa, and defective elastic fibers. There were distinct differences between the changes seen in CPVD with trisomy 18 syndrome and those seen in the normal individuals. The most severe changes were present in the tricuspid and mitral valves with derangement of the spongiosa and fibrosa and defective elastic fibers. The valve tissue had a similar histologic appearance and structure to that of low birth weight infants (gestational age, 25 weeks). The valvular changes observed therefore are of fetal type and represent errors in tissue differentiation occurring as last as the third trimester.

Familial agnathia-holoprosencephaly.

Two stillborn sisters had characteristics of both agnathia and holoprosencephaly. Familial occurrence implies that agnathia-holoprosencephaly may be determined by a single recessive gene, something to be taken into account when counseling such families. Evidence from human experience and various animal models suggests that agnathia-holoprosencephaly represents a causally heterogeneous single developmental field defect. Anatomical studies of these two stillborn sisters support the view that they shared a developmental field defect which affected structures in the face, cranial cavity, and upper neck. The pathogenesis of these variably expressed defects probably relates to defects in neural crest cells of cranial origin and/or to underlying mesodermal support elements of these cells.

The campomelic syndrome: review, report of 17 cases, and follow-up on the currently 17-year-old boy first reported by Maroteaux et al in 1971.

We report 17 cases of the campomelic syndrome (CS) and a follow-up of one of the original patients of Maroteaux et al who is now 17 years old. Our review is based on 97 patients, including our own. An infant with the CS presents at birth with spectacularly short and bowed femora and tibiae. The initial chest radiograph confirms the diagnosis by demonstrating extremely small bladeless scapulae and hypoplastic pedicles of many thoracic vertebrae. Ossification of the sternal segments, pubis, talus, and knee epiphyses is also retarded. Usually the hips are dislocated and talipes equinovarus deformities are present. There is a small chondrocranium and a disproportionately large neurocranium. The bell-shaped chest, narrow superiorly, does not explain the degree of respiratory distress that soon ensues. Narrow airways from defective tracheo-bronchial cartilage can often be demonstrated on the radiograph, but micrognathia, retroglossia, cleft palate, hypoplastic lungs, and even CNS-based hypotonia contribute to the respiratory problem. Internal anomalies include frequent absence of olfactory bulbs and tracts and dilatation of cerebral ventricles, heart defects (PDA, VSD, stenosis of aortic isthmus), hydroureter and hydronephrosis, renal hypoplasia, renal hypoplasia, and rarely renal cysts.

Brachymesomelia-renal syndrome.

We have studied a male Japanese infant with severe upper limb brachymesomelia, glomerulocystic renal dysplasia, abnormalities of the cranium and face, corneal opacities, and a possible congenital heart defect. He was born at term and died on the 10th day of heart and kidney failure. Review of the literature failed to show a similar case. Glomerulocystic renal dysplasia has been reported in association with a variety of the nonskeletal malformations but has not previously been described in association with bony malformations.
