Development of criteria for the classification and reporting of osteoarthritis: Classification of osteoarthritis of the knee

Abstract: For the purposes of classification, it should be specified whether osteoarthritis (OA) of the knee is of unknown origin (idiopathic, primary) or is related to a known medical condition or event (secondary). Clinical criteria for the classification of idiopathic OA of the knee were developed through a multicenter study group. Comparison diagnoses included rheumatoid arthritis and other painful conditions of the knee, exclusive of referred or para-articular pain. Variables from the medical history, physical examination, laboratory tests, and radiographs were used to develop sets of criteria that serve different investigative purposes. In contrast to prior criteria, these proposed criteria utilize classification trees, or algorithms.

Adrenergic Receptor Mediation of Renin Secretion

Abstract: The role of adrenergic receptors in mediating renin secretion was studied in normal subjects with the use of upright posture and administration of diazoxide, ethacrynic acid and theophylline to provoke renin release. Each of these stimuli produced the expected rise in plasma renin activity (PRA), despite marked differences in their effect on urinary sodium excretion. In each case the increase in PRA was markedly suppressed on retesting with an infusion of either phentolamine, an alpha-adrenergic blocking agent, or propranolol, a beta-adrenergic blocking agent, whereas adrenergic blockade had little or no affect on sodium excretion. Since the stimuli chosen for provoking renin release have diverse mechanisms of action, it is noteworthy that PRA was suppressed by adrenergic blockade, regardless of the stimulus used. These findings suggest that many, if not all, of the stimuli for renin release are mediated by a common pathway which may involve alpha-and beta-adrenergic receptors. Moreover, renin re...

The injection of nodules of Dupuytren's disease with triamcinolone acetonide.

Abstract: Over a 4-year period 63 patients (75 hands) with Dupuytren's nodules were treated with a series of injections with the steroid triamcinolone acetonide directly into the area of disease. The purpose of this study was to determine whether intralesional injections of triamcinolone acetonide could produce softening and flattening in nodules of Dupuytren's disease as seen in the intralesional injections of hypertrophic scars and keloids. After an average of 3.2 injections per nodule 97% of the hands showed regression of disease as exhibited by a softening or flattening of the nodule(s). Although some patients had complete resolution of the nodules, most experienced definite but incomplete resolution of the nodules in the range of 60% to 80%. Although a few patients did not experience recurrence or reactivation of the disease in the injected nodules or development of new nodules, 50% of patients did experience reactivation of disease in the nodules 1 to 3 years after the last injection, necessitating 1 or more injections. The findings of this study indicate that the intralesional injection of nodules of Dupuytren's disease with triamcinolone acetonide may modify the progression of the disease.

Association of paralabral cysts with acetabular disorders.

Abstract: OBJECTIVE. Acetabular labral tears may cause considerable pain and predispose patients to premature osteoarthritis. Therefore, early and accurate examination is required. Acetabular labral tears are difficult to view on MR images. We report the association of paralabral ganglion cysts detected on MR imaging with surgically proven acetabular labral disorders.CONCLUSION. Paralabral cysts may be associated with labral disorders. The appearance of a paralabral cyst on MR imaging is a useful indirect sign of acetabular labral abnormality. Use of this sign may enable earlier and more accurate examination of labral disorders.

MRI of meniscal bucket-handle tears.

Abstract: Objective. A meniscal bucket-handle tear is a tear with an attached fragment displaced from the meniscus of the knee joint. Low sensitivity of MRI for detection of bucket-handle tears (64% as compared with arthroscopy) has been reported previously. We report increased sensitivity for detecting bucket-handle tears with the use of coronal short tau inversion recovery (STIR) images.
