On the nature of rheumatoid rice bodies: an immunologic, histochemical, and electron microscope study.

The nature of rice bodies was studied, utilizing histochemistry, immunofluorescence, and scanning and transmission electron microscopy. Rice bodies were found to consist primarily of fibrous material, most of which was fibrin with small amounts of collagen. Channels containing a variety of viable cells permeated the rice bodies. Blood vessels occurred in a few rice bodies indicating a former connection with the synovial membrane. Nonvascularized rice bodies might represent a further degeneration of the vascular type. Rice bodies seem to be a nonspecific response to inflammation.

Deep muscle contusion complicated by myositis ossificans (a.k.a. heterotopic bone).

One muscle trauma is a common injury in contact sports. The most extensively damaged muscle is that segment closest to the underlying bone. By an unknown mechanism, this injured muscle can become transformed into heterotopic bone, a complication also called myositis ossificans. It is best managed conservately and rarely requires surgery.

Synovial osteochondomatosis.

Synovial osteochondomatosis is a benign, metaplastic disease of unknown etiology in which synovial tissue can differentiate into cartilage and/or bone. This cartilage and bony tissue may be attached to the synovium or may break free and become intraarticular loose bodies. The treatment of choice for this unusual condition is synovectomy, which is usually curative.

Cardioplegic cardiac arrest in aortic surgery.

Cardioplegia according to Bretschneider is able to protect the myocardium during long periods of cardiac arrest and a quiet relaxed heart has in many cases of congenital heart disease been of great surgical advantage. In the last 100 consecutive aortic valve replacements in cardioplegic arrest we have lost 6 patients and none of the deaths seems to be related to the method. In our hands it has been superior to coronary perfusion.

A clinical comparison of four denture adhesives.

The influence of four denture adhesives (Fittydent, Super Poligrip, Super Wernet's, and tragacanth) on patients' opinions of 10 aspects of denture use was studied. The adhesives were applied in turn to the existing complete dentures of 32 patients in a sequence determined by eight randomly chosen 4 x 4 Latin squares of different treatments. Subjective views of the patients indicated that one product significantly improved denture retention and had other favorable features.

X-ray diagnosis of healing fractures in rabbits.

Do X-rays adequately reflect the strength of callus post fracture? Eleven rabbit tibiae were manually fractured and allowed to heal in plaster. At varying times post fracture, the rabbits were sacrificed and the tibiae were removed. AP and lateral X-rays of each tibia were obtained and shown to 27 orthopedists and radiologists who were asked to rank the bones in order of strength. The valid ranking was done using data obtained by loading the bones axially to failure in an Instron machine. Each physician's ranking was compared with that obtained from the Instron with a median correlation level p=0.0668. This implies that a physician, whether an orthopedist or radiologist, is not very reliable at determining early osseous union.

Calcific tendinitis of the shoulder.

Calcific deposits in tendinous tissue are common to middle-aged patients. The condition usually resolves spontaneously, but refractory cases can be expedited by needle barbotage or surgery.
