Syndromatic hepatic ductular hypoplasia (arteriohepatic dysplasia): a clinical and hepatic histologic study of three patients.

Clinical and pathologic features of three patients with chronic intrahepatic cholestasis from birth are described. Each patient exhibited a paucity and hypoplasia of interlobular bile ducts, unusual facies, short stature, a pulmonary ejection systolic murmur, and structural anomalies of vertebrae. This constellation of defects constitutes a distinct syndrome to which the terms arteriohepatic dysplasia and syndromatic hepatic ductular hypoplasia are applied. Clinically, cholestasis was not progressive and, although the SGPT was chronically elevated (122--520 units/liter), features of liver cell failure did not develop. Changes in plasma lipids and lipoproteins and serum bile acids were consistent with chronic cholestasis. Liver biopsies from the three cases revealed pseudoxanthomatous change, increased stainable copper and mild hepatocellular degenerative changes. Electron microscopy of one of the liver biopsies revealed extension of thick bundles of collagen from portal areas into hepatic lobules with obliteration of the space of Mall. With increasing age, portal tracts contained fewer bile ducts. This apparent progression of the lesion was not associated with an inflammatory cell infiltrate, progressive fibrosis, or the development of cirrhosis.

MR of the pituitary in patients with Prader-Willi syndrome: size determination and imaging findings.

Prader-Willi syndrome (PWS) is an unusual genetic disorder characterized by short stature, obesity, hypogonadism, hypotonia, cognitive impairment, and dysmorphic facies. There is an interstitial deletion of the proximal long arm of chromosome 15 in about 70 % of patients. Some of these clinical features suggest a central hypothalamic/pituitary dysfunction, and recent investigations have demonstrated a marked impairment in spontaneous growth hormone (GH) secretion. We studied 15 GH-deficient PWS patients by magnetic resonance imaging (MRI) to determine whether there was a diminution in the gross morphological size of the anterior pituitary gland, the site of GH synthesis. We also set out to catalog the pertinent imaging findings in this patient population. Our results indicate that this is the first report documenting pituitary size by MRI in PWS patients. No statistically significant difference was found in the height of the anterior pituitary gland in PWS patients compared with either normal children or children with isolated GH deficiency. An interesting imaging finding is that three of 15 patients (20 %) demonstrated complete absence of the posterior pituitary bright spot (PPBS), and a fourth patient demonstrated a small PPBS. These observations reflect an objective physiologic disturbance in the hypothalamus. The clinical and radiologic implications of these findings are discussed.

I-cell disease.

A 6-month-old female infant presented with severe psychomotor retardation, coarse facies, gingival hyperplasia, thick skin, restricted joint movements and radiological features suggestive of the Hurler syndrome. Her urine showed no excess excretion of mucopolysaccharides. I-cell disease was suspected from the onset of clinical features in early infancy, the subsequent progress and the absence of mucopolysacchariduria. Marked elevation of the activity in serum of three lysosomal enzymes confirmed the diagnosis. This patient had repeated convulsions, a feature not previously reported in this condition. This is the first case report of I-cell disease from India.

Evolution of the neuroimaging changes in fucosidosis type II.

We report on clinical and neuroradiological findings in two patients with fucosidosis type II; a 7-year-old Jordanian boy and a 3 1/2-year-old Anglo-Canadian girl. This rare, autosomal recessive disorder is caused by deficiency of lysosomal alpha-fucosidase and is manifested clinically by progressive mental and motor deterioration, coarse facies, growth retardation, recurrent infections, dysostosis multiplex, angiokeratoma corporis diffusum, visceromegaly and seizures. Cranial CT and magnetic resonance imaging showed density and signal abnormalities in the thalamus, globus pallidus and internal capsules bilaterally, as well as progressive CT density alterations in supratentorial white matter including the internal medullary laminae of the thalami and the internal capsules.

The "axial sacroiliac joint".

This article describes an iliac prominence and a sacral cavity, located extracapsularly approximately 15 mm dorsal to the angle created by the auricular facies of the sacroiliac joint. These bony structures are often covered by cartilage on one side, usually on the iliac prominence. The sacral cavity is occupied by areolar tissue, rich in adipocytes. They interface very closely, forming an extracapsular junction, which we have named the "axial sacroiliac joint". The study comprised 27 anatomical specimens, 3 of which were found to be ankylosed. Among the remaining 24, and iliac prominence was demonstrated on 22, and a sacral cavity on all. Descriptions and measurements of the sacroiliac joint, the "axial sacroiliac joint", and the spatial relationships are presented, the sacroiliac joint being the joint of reference. The study includes microscopy of the "axial sacroiliac joint".

The Costello syndrome: a boy with thick mitral valves and arrhythmias.

A 3-year-old boy with Costello syndrome is reported. He had typical clinical features of the syndrome including severe postnatal growth retardation, poor sucking, mild developmental delay, a coarse characteristic facies, thick and loose skin of the hands and feet, sparse and curly hair, dark skin, and relative macrocephaly but lacked nasal papillomas. In addition, he had cardiac anomalies with extrasystoles and thick mitral valve tips. Mitral valve defects may be a clinical feature of the syndrome.

Nature in the laboratory--nature as a laboratory. Considerations about the ethics of release experiments.

Field tests with genetically modified organisms go beyond the boundaries of the politically and morally neutralized space that normally surrounds scientific experiments. They enter public areas. As a social process of shaping nature they are political in a fundamental sense. Consequences of this observation concern the legitimacy of decisions and the legitimacy of deciding procedures. The political rights of citizens and their human rights can only be respected if these procedures are democratic. Without a more serious exploration of the specific circumstances of release tests--for example, the precise ecological context, the consequences for the future development of the affected ecosystem, the social consequences, and the possible institutional ways of establishing gene technology in agriculture--we do not really know what we are doing when we release transgenic organisms. Moral judgements today can therefore only be prima facie, not free from shortcomings. As responsible judges we must confess that we are still morally blind.

Hypogonadism in a patient with balanced X/18 translocation and pituitary hormone deficiency.

The case of a girl carrying a balanced X/autosome translocation: 46,X,t(X;18)(q22.3;q23),inv(9)(p11q13) and pituitary hormone deficiency (growth hormone and gonadotropin) is described. The patient had a doll-like facies, with frontal bossing and poor development of the nasal bridge, increased adipose tissue especially of the trunk, short stature and absence of pubertal development without Ullrich-Turner stigmata apart from urinary tract malformation. The lack of spontaneous puberty seems related both with gonadotropin deficiency, as suggested by hormonal data and MRI of the pituitary region, and with gonadal dysgenesis, due to the X/autosome translocation, involving the critical region of the X chromosome essential for normal ovarian function. Growth velocity was unsatisfactory during growth hormone treatment; a higher dose of growth hormone similar to that used in Ullrich-Turner patients, would probably have improved her growth rate.

Myopathy in Williams-Beuren syndrome.

Williams-Beuren syndrome (WBS) is a disorder of unknown aetiology. The classical features of the syndrome include a typical ('elfin') facies, mental retardation and heart defects. Myopathy has not so far been part of the spectrum of WBS. We studied six patients with WBS aged 3-25 years, five of whom showed clinical and morphological evidence of myopathy. The clinical manifestations of myopathy included hypotonia in infancy, walking delay, joint contractures, scoliosis, and increased exhaustion on exertion. These symptoms were present in variable expression but part of a typical postural pattern. Examination of muscle biopsies showed lipid storage in four patients and increased variability of fibre size in three. In one patient a muscle biopsy gave normal results. Biochemical investigation in four patients with morphological evidence of lipid storage in muscle revealed muscle carnitine deficiency in three. In addition, enzyme activities of fatty acid beta-oxidation were low in one of two specimens tested. It is concluded that a clinically relevant myopathy is part of the multi-system manifestation of WBS and a clinical trial of carnitine supplementation is justified.

Severe mid-cervical kyphosis with cord compression in Larsen's syndrome and diastrophic dysplasia: unrelated syndromes with similar radiologic findings and neurosurgical implications.

Mid-cervical kyphosis in diastrophic dysplasia (DD) with cord compression and weakness has been recognized for the last three decades. A strikingly similar situation exists in Larsen's syndrome (LS), an otherwise unrelated problem of weakness with lay joints and dislocations with typical facies. Forty patients with DD were studied of whom seven had cervical spine kyphosis: one patient had spontaneous correction over the ensuing two decades. Seven patients with LS were studied of whom four had cervical spine changes with cord compression. There was one sudden death among the patients with LS and no cases of spontaneous correction. Muscle weakness in DD and LS should lead to evaluation of cervical spine kyphosis with cord compression. Plain films, CT and recently MRI are useful.

A new form of rhizo-mesomelic bone dysplasia.

A new form of rhizo-mesomelic dwarfism in an 8 1/2-year-old gypsy Slovakian girl is reported. This patient shows some superficial similarity to patients with Robinow syndrome. However, different facies, normal external genitalia and absence of radiographic abnormalities characteristic of Robinow syndrome (malsegmentation of the spine and ribs, short, small tubular bones and bifid terminal phalanges) as well as mesomelic hypoplastic/dysplastic changes in the forearm bones allow us to separate this disorder as a distinctive entity.

Schinzel-Giedion syndrome and congenital megacalyces.

The Schinzel-Giedion syndrome is a rare autosomal recessive condition with typical facies, skeletal manifestations and congenital hydronephrosis. We report an infant with characteristic findings who had bilateral congenital megacalyces. Congenital megacalyces is believed to be a developmental abnormality, occurs in other malformation syndromes and has not previously been described in the Schinzel-Giedion syndrome.

Papular mucinosis, destructive arthropathy, median neuropathy, and sicca complex.

A patient with papular mucinosis (scleromyxedema) developed an erosive seronegative rheumatoid-like arthropathy, carpal tunnel syndrome, sicca complex, and marked increase in TG(OKT8) suppressor/cytotoxic circulating T-cells akin to that reported in scleroderma. Sclerodactyly, acrolysis and stiff digits were striking but other features of scleroderma, i.e., Raynaud's and esophageal hypoperistalsis, were absent. The diagnosis of papular mucinosis, a pseudoscleroderma syndrome, should be considered in a patient with atypical arthritis, median neuropathy, myopathy, and/or sclerodactyly and a papular lichenoid dermatopathy. Skin mucin stain and the demonstration of the distinct serum paraprotein (PM-spike) are confirmatory. We stress the salient diagnostic clinical features of the leonine-like facies of papular mucinosis.

The Prader-Willi syndrome: neuroendocrine study of identical twins.

Identical twins with the Prader-Willi syndrome are reported. Apart from hypogonadism, hypomentia, hypotonia and obesity, they presented shorter than normal stature and the peculiar facies of this syndrome. Both twins also suffered from arterial hypertension with secondary hyperaldosteronism, an abnormality never previously recorded. The endocrinological study showed the presence of hypogonadotrophic hypogonadism in both twins. The GnRH and clomiphene tests suggested a hypothalamic disorder. Although the vast majority of cases with the Prader-Willi syndrome are isolated, the expression of this disorder in two identical twins enhances the possibility of a genetic determination.
