Synovial chondromatosis affecting the glenohumeral joint is rare. Treatment primarily consists of arthroscopic loose body removal and synovectomy. Shoulder arthroplasty has been mentioned in the literature as a treatment option for patients with coexisting arthritis, although the results have been underreported. The case of an 84-year-old man with long standing synovial chondromatosis of the sh...

This study was conducted to estimate the prevalence of migraine and tension-type headaches among Shiraz primary schools teachers and to provide an epidemiologic model for them. A random sample of 538 teachers, constituting a 10% sample of the primary schools teachers’ population, was evaluated on the basis of the diagnostic criteria of the International Headache Society (IHS) as well as clinica...

BACKGROUND Loss-of-function mutations of vitamin D-24 hydroxylase have recently been recognized as a cause of hypercalcaemia and nephrocalcinosis/nephrolithiasis in infants and adults. True prevalence and natural history of this condition are still to be defined. METHODS We describe two adult patients with homozygous mutations and six related heterozygous carriers. Mineral and hormonal data i...

Abst rac t -Oxygen isotopic compositions were determined for coexisting mixed-layer serpentine-chlorite (Sp-Ch) and illite-smectite (I-S) from 5 Tuscaloosa Formation sandstone cores sampled between 1937 and 5470 m burial depth. High gradient magnetic separation (HGMS) was used to concentrate Sp-Ch and I-S from the <0.5 p~m fraction of each core sample into fractions with a range in the Sp-Ch : ...

Experimental approaches attempt to determine the routes by which crustal carbonatite magmas can be derived from C02-bearing peridotite at high pressures. The intimate association of kimberlite and carbonatite on a small scale il· lustrates links in the processes. Carbonation of peridotite by C02 can cause the generation of near-solidus carbonatitic liquid from mantle peridotite at depths greate...

Supersymmetry (SUSY) breaking without messenger fields is proposed. We assume that our world is on a wall and SUSY is broken only by the coexistence of another wall with some distance from our wall. The Nambu-Goldstone (NG) fermion is localized on the distant wall. Its overlap with the wave functions of physical fields on our wall gives the mass splitting of physical fields thanks to a low-ener...
