A case of right coronary artery occlusion, caused by blunt chest trauma and treated with acute coronary artery bypass surgery.

A 37-year-old man sustained occlusion of the right coronary artery after a bicycle accident with blunt chest trauma over the left scapula. Acute coronary angiography was performed because of chest pain and ST-segment elevation. Despite surgically successful acute revascularization the patient developed a transmural inferior wall infarction. Coronary artery occlusion after blunt chest trauma is rare, especially occlusion of the right coronary artery. When it occurs, the impact is usually frontal (car accidents), and not dorsal as in this case. Coronary artery bypass surgery has been reported in a few cases but to the best of our knowledge this is the first report of bypass surgery at the stage of acute transmural ischaemia.

Increased serum concentrations of cartilage oligomeric matrix protein. A prognostic marker in early rheumatoid arthritis.

Two cartilage specific macromolecules, cartilage oligomeric matrix protein (COMP) and proteoglycan, were quantified by immunoassay in sera of two groups of patients with rheumatoid arthritis (RA) of recent onset to evaluate the prognostic value of such measurements. Patients with rapidly progressive joint destruction had increased COMP concentrations initially, which subsequently decreased. A group with more benign disease, and less extensive joint damage, had normal COMP levels throughout the study period. Serum concentrations of proteoglycan were normal in both groups. Thus measurement of COMP in serum early in the course of RA holds promise as a prognostic marker for development of joint destruction in this disease.

Does primary fibromyalgia exist?

Twenty-one of 25 consecutive primary fibromyalgia or fibrositis patients, identified during a 5-year period in a tertiary care day-ward for pain syndromes, were re-examined. Fifteen fulfilled criteria for fibromyalgia but unexpectedly, all cases had either psychiatric disturbance or thyroid dysfunction. Of the four patients not seen at follow-up, two had developed neurological diseases, another rheumatoid arthritis and one other hypothyroidism. Thus, after 5 years no patient fulfilled the criteria for primary fibromyalgia. Women occupied as manual workers were over-represented. Most patients reported beneficial effects of physiotherapy. None of the patients has been able to return to full time work.

Direct assessment of synovial blood flow and its relation to induced hydrostatic pressure changes.

A method for measuring synovial blood flow changes using the laser Doppler technique is described. Mean blood flow and mean pulse amplitude decreased by 50-70% in relation to the reference level when the intra-articular hydrostatic pressure in effusive knee joints of patients with rheumatoid arthritis was increased. As an increase of intra-articular pressure of as little as 20 mmHg decreased synovial blood flow significantly it is suggested that hypoxia may occur in vivo during joint use in the presence of an effusion. This may be of aetiopathogenetic importance for tissue destruction and the persistence of chronic synovitis.

Alkaptonuria and ochronosis in three siblings. Ascorbic acid treatment monitored by urinary HGA excretion.

Patients with alkaptonuria lack homogentisate 1,2-dioxygenase leading to retention of homogentistic acid (HGA) in body fluids and eventually to tissue deposition of oxidation products, giving rise to the clinical picture of ochronosis. Ascorbic acid is a known inhibitor of the enzyme which catalyses the oxidation of homogentisic acid (HGA) to the polymer with affinity for collagen and was used in the treatment of three siblings with alkaptonuria. Ascorbic acid 500 mg bid was administered for 12 months. Two of the siblings tolerated the treatment, and in one the symptoms improved, whereas in the other they worsened. Plasma and urinary levels of HGA were monitored with a new HPLC method. Ascorbic acid is not effective in the treatment of symptomatic ochronosis.
