[Clinical and genetic aspects of hereditary acro-osteolysis].
The report concerns a description of a case of hereditary acroosteolysis with peculiar clinical and X-ray symptoms. It is being stressed that the neurological changes in different cases differ by their manifold signs and are sometimes the prevalent syndrome. The authors conducted a genetical analysis of 11 cases of hereditary acroosteolysis, which were seen in Dagestan. The paper contains some considerations of the differencies of hereditary acroosteolysis from other similar disorders.

The Hajdu-Cheney syndrome. Report of two cases and review of the literature.
The Hajdu-Cheney syndrome includes short stature, characteristic facies, and a slowly progressive skeletal dysplasia which affects skull, spine, and long bones. Two patients with this syndrome are presented. In the first patient the most distinctive skeletal feature, acro-osteolysis, was shown to be absent at age 6 years but was present at age 11 years. Diagnosis was made in the second case in the absence of acroosteolysis because of otherwise typical findings. Abnormalities affecting vision, hearing, and dentition occur and these, along with the other characteristic physical and radiographic features of the syndrome, should enable diagnosis prior to the onset of acro-osteolysis.

[Essential osteolysis. Study of 3 cases and a classification trial].
Disappearing bone disease is a rare syndrome, characterized by an idiopathic and spontaneous progressive resorption of bone, for which different etiologies must be considered. The classification of this disease is difficult; acro-osteolysis involves the phalanges or the carpus and tarsus. Massive osteolysis corresponds to diffuse multicentric cystic hemangiomatosis and Gorham and Stout's disease. We describe two cases of acro-osteolysis and one of Gorham and Stout's disease. The mechanism of disappearing bone disease remains unknown and no treatment has yet been found to stop its evolution.

Hajdu-Cheney syndrome.
Hadjdu-Cheney syndrome is a rare type of syndrome characterized by acro-osteolysis, dolichocephaly with multiple Wormian bones, absence of frontal sinuses and joint laxity. A case of this syndrome is presented. A histological study of the osteolytic lesion revealed destruction characterized by microfractures with a poor reparative process. It is postulated that an abnormality of osteoblast or osteoid function is the pathogenesis of this syndrome.

Hajdu-Cheney syndrome: MR imaging.
Hajdu-Cheney syndrome is a rare congenital disease with acro-osteolysis, osteoporotic changes of the spine and long bones of extremities and marked basilar invagination with an unusually deformed skull. Magnetic resonance imaging of a 32-year-old male revealed the deformed skull and almost horizontal basal angle and the elongated and upwardly shifted brain stem caused by the tip of the odontoid process of the second cervical vertebra invaginating the base of the skull. In addition there were atrophic pituitary gland, widely open sella turcica and symmetrical fluid collections along the optic nerve sheath.

Autonomic neuropathy and secondary hyperparathyroidism in uremia.
To evaluate the relationship between autonomic neuropathy, and biochemical and radiological parameters of secondary hyperparathyroidism, we examined 19 predialysis and 24 hemodialysis non-diabetic uremic patients. Autonomic neuropathy was assessed using four cardiovascular tests. Ten predialysis and 15 hemodialysis patients showed abnormalities in one or more autonomic tests. Ca, Ca2+, P, alkaline phosphatase, immunoreactive parathyroid hormone and osteocalcin did not significantly differ in uremic patients with and without abnormal autonomic test results. Radiological markers of hyperparathyroidism such as acro-osteolysis (score A) and subperiosteal resorption (score B) were more common in patients with abnormalities in autonomic tests than in patients without. When predialysis and hemodialysis patients were considered separately, the correlation between score A, score B and autonomic neuropathy was confirmed only in hemodialysis patients. In conclusion, autonomic neuropathy is not related to biochemical parameters of hyperparathyroidism, while it appears correlated with radiological signs of osteodystrophy, suggesting a possible pathogenetic link between autonomic neuropathy and secondary hyperparathyroidism.

[Acropathia ulcero-mutilans non familiaris (Bureau-Barrière). (Case report with special reference to the x-ray findings) (author's transl)].
Four cases of non-familiar acropathia ulcero-mutilans (Bureau-Barriere) are described. In all cases there was a history of alcoholism, abnormal liver function, painless foot ulcers and polyneuritis. The radiological changes were confined to the lower extremities. There were osteolytic changes in the metatarsal heads and the bases of the proximal phalanges, particularly of the great toes; in addition, there was general demineralisation of the bones of the feet. One case was remarkable in that the tarsal bones and the proximal protions of the metatarsals were also involved. A variety of bone deformities were observed, and there were pathological fractures as well as subluxation and dislocation. The differential diagnosis between familial and non-familial acro-osteolysis, and of some other bone abnormalities is discussed. A multifactorial pathogenesis of the disease is suggested.

Autonomic neuropathy and secondary hyperparathyroidism in uraemia.
To evaluate the relationship between autonomic neuropathy, and biochemical and X-ray parameters of secondary hyperparathyroidism, we examined 19 predialysis and 24 haemodialysis non-diabetic uraemic patients. Autonomic neuropathy was assessed using four tests: deep breathing, Valsalva manoeuvre, lying to standing, and postural hypotension. Serum Ca, Ca2+, P, Mg, alkaline phosphatase, iPTH, and osteocalcin were assayed. Hand X-ray was obtained to evaluate acro-osteolysis (score A) and subperiosteal resorption (score B). Ten predialysis patients (52%) and 15 haemodialysis patients (62%) showed one or more abnormal autonomic tests. Age, dialysis duration, and biochemical parameters of secondary hyperparathyroidism did not differ significantly in uraemic patients with and without abnormal autonomic tests. Furthermore, there was no significant relation between autonomic tests and iPTH or osteocalcin. Score A and score B was significantly greater in patients with abnormal tests than in patients without (P less than 0.009 and P less than 0.025). When predialysis and haemodialysis patients were considered separately the correlation between score A, score B, and autonomic neuropathy was confirmed only in haemodialysis patients. In conclusion, autonomic neuropathy does not seem to be related to the biochemical parameters of secondary hyperparathyroidism, while it appears significantly associated with the radiological signs of osteodystrophy, suggesting a possible pathogenetic linkage between autonomic neuropathy and secondary hyperparathyroidism.

Immunological mechanisms in the pathogenesis of vinyl chloride disease.
Vinyl chloride (VC) disease is a multisystem disorder incorporating Raynaud's phenomenon, acro-osteolysis, thrombocytopenia, portal fibrosis, and hepatic and pulmonary dysfunction. Immunological and immunochemical investigations showed the presence of circulating immune complexes in 19 out of 28 patients with the disease and in a further two out of 30 workers exposed to VC. The immunological data were reviewed in relation to the clinical picture of the disease and to the available evidence on the metabolism of VC. The results suggest that VC disease is an immune complex disorder and that the immune response is initiated by the adsorption of VC or a metabolite on to tissue or plasma protein.

The musculoskeletal manifestations of epidermolysis bullosa: an analysis of 19 cases with a review of the literature.
Epidermolysis bullosa encompasses a group of rare disorders characterized by marked skin fragility and blister formation. In patients with dystrophic epidermolysis bullosa, skeletal and soft-tissue abnormalities are an important feature. An analysis of the musculoskeletal manifestations in 19 patients is presented. In the hands and feet, features included generalized osteoporosis, wedge-shaped thinning and hooking of distal phalanges, overconstricted bones, acro-osteolysis, flexion contractures, metatarsal and metacarpal subluxation, distal trophic changes, webbing of digits, encasement of the whole extremity in a pouch of skin, soft-tissue calcification and retarded skeletal maturity. Previously undescribed findings in the hands and feet are bony ankylosis of the proximal interphalangeal joints, resorption of the metatarsal and metacarpal heads, shortened metatarsal bones, carpal and tarsal fusion and destruction, and cystic changes of the distal radius and ulna. In the remainder of the skeleton, hip dysplasia with premature osteoarthritis, knee joint bony ankylosis and thoracic and thoraco-lumbar scoliosis are other undescribed findings.

Vinyl chloride-associated liver disease.
Although polyvinyl chloride has been produced from vinyl chlride monomer for more than 40 years, recognition of toxicity among vinyl chloride polymerization workers is more recent. In the mid 1960s, workers involved in cleaning polymerization tanks were found to have acro-osteolysis. In 1974, the same population of workers was found to be at risk for an unusual type of hepatic fibrosis and angiosarcoma of the liver. We describe two cases of vinyl chloride-associated liver injury, one of hepatic fibrosis and one of angiosarcoma. Histologic features of these lesions are similar to the hepatic fibrosis and angiosarcomas resulting from chronic exposure to inorganic arsenicals. Preliminary studies suggest that the toxicity of vinyl chloride may result from formation, during high-dose exposure, of active metabolites by mixed function oxidases of the liver. Epidemiologic studies indicate an increased incidence not only of liver disease, but also of cancers of the brain, lung, and possibly other organs.

[The pycnodysostosis (author's transl)].
Two own observations of pycnodysostosis initiated our description of this disease. Inherited as an autosomal recessive trait the syndrome is characterized by a medium degree generalized osteosclerosis, open craniial sutures and fontanels until adult lige, hypoplastic mandibles with deficiency of the angle, prominence of the forehead and occiput, hypoplasia of the paranasal sinuses, commonly observed dysproportionate dwarfism, acro-osteolysis and increased bone fragility. Contrary to osteopetrosis the prognosis is good.

Diagnostic imaging in hypertrophic osteoarthropathy.
This review discusses our experience with conventional radiography and advanced imaging techniques in the evaluation of diverse soft tissue, skeletal and joint abnormalities frequently observed in patients with both the primary and secondary forms of hypertrophic osteoarthropathy. The manifestations include finger clubbing, elephant feet, cutis verticis gyrata, synovial effusion, periostosis, tuftal hypertrophy and acro-osteolysis. Its coexistence with other skeletal and joint diseases and its imaging differential diagnosis are also reviewed.

[Early acroparesthesia in females: a sign disclosing heterozygote Fabry disease].
Heterozygous Fabry's disease has an inconstant expression and very few complications. The theory of X-chromosome inactivation which, according to Lyon, occurs hazardly, is illustrated by the fact that the disease is expressed even in hemizygous women. Ophthalmic manifestations, as detected by the slit lamp method, are almost constant, 80 p. 100 of women with the disease having a verticillate cornea. Angiokeratoma is present in 20 p. 100 of the cases. Episodes of paraesthesia of the hands and feet are less common; in most cases they are attributed to the disease retrospectively, during family investigations. In two girls aged 10 and 11 years respectively and without history of Fabry's disease the only symptom suggestive of the diagnosis was paroxysmal acroparaesthesia. In one of the girls acroparaesthesia was associated with acrocyanosis, livedo and acro-osteolysis, but concordance was the only argument in favour of a link with Fabry's disease. Alterations of the extremities have been reported in this disease, including palmar erythema and a bluish discoloration of the palms due to dilatation of the superficial veins. Only two cases of livedo have been published. Acrosteolysis has never been documented in Fabry's disease, and its presence must be confirmed in further cases. The diagnosis of heterozygous Fabry's disease in these 2 girls was confirmed by the finding of ceramide trihexoside in urine and by leucocyte alpha-galactosidase levels that were 25 to 30 p. 100 of values obtained in controls. A study of the family of one of the girls showed that the father was involved; this hemizygous type of the disease with a 10 p. 100 alphagalactosidase level was totally asymptomatic.(ABSTRACT TRUNCATED AT 250 WORDS)

Lethal progeroid syndrome with osteolysis. Case report.
A particular progeroid syndrome with severe acro-osteolysis, cutaneous changes, failure to thrive, and early death is described in a young boy. Progeria and mandibulo-acral dysplasia are discussed, but early death is unusual in these two syndromes. This observation raises the question of a large spectrum including all of these syndromes.
