[Epicondylitis of the humerus (author's transl)].

Principles of Treatment and Results after Hohmann's Operation: The method of clinical examination and rational conservative measures including physiotherapy are discussed in the light of the literature and the results of a cooperative study. To summarize briefly it may be said that conservative therapy should first of all be completely exhausted. Local injections of a corticosteroid should not exceed 3 and at most 6. If conservative therapy is unsuccessful after 4 months, operation is indicated and the extended Hohmann operation performed.

[Biorheologic study of pathological synovial fluids].

Rheometric studies of 34 synovial fluids done using a rheometer with a cone and stage (Shirley-Ferranti type) showed that arthrotic synovial fluids had pseudoplastic characteristics (non-Newtonian) but in inflammatory rheumatisms, the characteristics index rises, the consistency decreases and the fluid tends to loose its pseudoplastic properties and to become Newtonian. Radioisotope synoviorthosis seems capable of restoring to a certain extent and in certain cases the rheometric characteristics of the pseudoplastic properties.

Mechanisms involved in mandibular condylopathy secondary to intraarticular injections of glucocorticoids.

Pharmacologic doses of triamcinolone hexacetonide were injected intramuscularly or intraarticularly in immature Papio papio baboons. The mandibular condyle served as a model for histologic examinations concerning the effect of glucocorticoid hormone on cartilage and bone. Biochemical examinations of blood and urine indicated the development of distinct hypophosphatemia, hypercalcemia followed by hyperphosphaturia, and hypocalciuria. Serum alkaline phosphatase activity rose during the initial phases of the experiment but decreased considerably after the sixth injection of the hormone. Hyperglycemia and an increase in serum amylase were noticed along with signs of moderate metabolic acidosis. Histologic examinations disclosed signs of severe destruction of cartilage and bone. By the sixth intraarticular injection, definite fibrillation was noted in the articular cartilage, followed by complete disappearance of cartilage. The subchondral bone appeared to be adversely affected by the hormone as it lost its typical lamellar organization and attained the characteristics of woven bone. The condyle showed clear signs of fibro-osseous transformation, with fibrosis as the dominant structural feature. The preceding biochemical and morphologic findings are indicative of parathyroid hyperactivity.

Comparison of intra-articular methotrexate with intra-articular triamcinolone hexacetonide by thermography.

A comparison of intra-articular methotrexate and intra-articular triamcinolone hexacetonide was made in 42 arthritic patients with persistent bilateral knee effusions. One knee was injected with either 5 mg methotrexate (two injections of 2.5 mg a week apart) or a single injection of 20 mg triamcinolone. An objective assessment of both knees was made by quantitative thermography at 0,3,7,14 and 21 days. Joints injected with triamcinolone showed a greater fall in thermographic index (T.I) than the joints injected with methotrexate, which showed similar change to the non-injected knee joints in both groups. Four patients received larger doses of methotrexate, up to 20 mg, though the fall in T.I. was still less than the mean fall for triamcinolone injected joints. Peak venous blood levels of methotrexate were reached 1 hour after intra-articular injection, and a sphygmomanometer cuff inflated around the leg above the injected knee for periods of up to 1 hour did not appreciably delay this. Methotrexate had no immediate anti-inflammatory effect, even in psoriatic arthropathy, and did not give the relief of intra-articular steroid.
