[Chronic osteitis and arthritis of palmoplantar pustulosis. A familial form of B-27 negative spondylarthropathy].

A 35-year old woman presented with pustulosis palmaris et plantaris evolving in acute episodes parallel to those of a rheumatic disease consisting of bilateral sacro-iliac arthritis, manubriosternal fusion and sterno-clavicular arthritis. Her brother had spondylitis compatible with the diagnosis of pustular osteo-arthritis though without pustulosis. He presented with bilateral sacro-iliac arthritis, manubriosternal fusion, sterno-clavicular arthritis and an ossified fragment detached from the antero-inferior angle of C6. The two patients had the same HLA phenotype: A1, A9, B5, B41, CW4, DR2, DR4, absence of B27. In a specimen from the sacro-iliac joint the authors found active bone remodelling and inflammatory osteitis with fibrosis and infiltrates rich in mononucleate cells. An electron microscopic study--to the authors' knowledge, the first to be performed in such cases--demonstrated intracytoplasmic filamentous inclusions in two macrophages of the synovial fringe. Only one other case of the familial form has been published so far. Like the rheumatism of acne conglobata, the spondylitis of pustulosis palmaris et plantaris is one of the causes of sterno-costo-clavicular hyperostosis.

[Characteristics of benzodiazepine consumption in patients hospitalized in an internal medicine department].

We have studied benzodiazepines (BZD) intake among 129 patients admitted in an internal medicine unit. In this population, we have differentiated long term (over 4 months) users (n = 25), occasional users (n = 24), and non users (n = 80). Analysis of the results favoured the fact that BZD users were, more than non users, alike to have a history of cardiovascular and/or rheumatic diseases, to have had multiple surgical procedures and that these patients often took several other psychotropic and non psychotropic drugs. Particular characteristics of long term users are discussed next (prevalence, sex ratio, incidence of depression).

[X short arm deletion and Turner syndrome. A new case 46, X, del (X) (p11) (author's transl)].

From a new case of a young woman with a rare X short arm deletion on band 11 and review of literature, it is suggested that loss of short arm by juxta-centromeric break does not involve complete somatic Turner syndrome. Short stature depends on distal deletion (p21 or p22). The p11 - p21 segment of X chromosome carries a gene essential for gonadal development.
