[Urban culture and physical and sports activities. The "sportification" of parkour and street golf as cultural mediation].

The article explores the process of "sportification"--i.e., processing physical activity in a sport regulated by a set of rules and standards, legitimized by supervisory institutions--from two originals practices, parkour and urban golf.

[Pseudo-Still disease and deep neoplasm].

Some rare observations with the diagnosis of Still's disease in adults reveal a different diagnosis: a paraneoplasic syndrome related to a non differentiated bronchitic carcinoma. The term "paraneoplasic pseudo Still's disease" can be considered. However we have to add a syndrome of intestinal dysfunction with characteristics of pseudoblockage with an imprecise mechanism.

Premature termination codon at the sterol 27-hydroxylase gene causes cerebrotendinous xanthomatosis in a French family.

Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive lipid-storage disease caused by mutations in the sterol 27-hydroxylase gene (CYP27). So far several mutations causing CTX have been identified and characterized. A new mutation creating an insertion of cytosine at position 6 in the cDNA, which is expected to result in a frameshift and a premature termination codon at codon 179, has been identified in a French family.

[Clinical and developmental aspects of Horton's disease. Retrospective study of 100 cases].

100 patients, from three internal medicine departments, were the subject of a retrospective study concerning the clinical manifestations and the evolution of Horton's disease. The mean age is 71 years, with a 2/1 female predominance. A temporal artery biopsy was obtained in all cases.

[Specific renal lesions revealing the presence of sarcoidosis (author's transl)].

Three cases of granulomatous nephropathy are reported. In two patients this was definitely related to a true renal sarcoidosis, while the third case raised the problem of the significance of an "isolated sarcoidosis nodule". The authors discuss the frequency, clinical symptoms, and pathological appearances of these renal lesions which reveal the presence of sarcoidosis, as well as the relationship between renal insufficiency and the parenchymatous lesions observed, and therapy.

[Idiopathic arteriovenous fistula of the renal peduncle (author's transl)].

Idiopathic arteriovenous fistulae in the renal peduncle are rare. A case was discovered during clinical examination, and was confirmed by total and selective arteriography. A vertebral and dise infection of L3-L4 was also present and blood cultures were positive for enterococcus.
