Randomized Controlled Trial Comparative Study Clinical TrialLong-term effect of intra-articular injections of sodium hyaluronate and corticosteroid on temporomandibular joint arthritis.
The long-term effect of intra-articular injections of sodium hyaluronate and corticosteroid (betamethasone) was compared in a sample of 24 patients who had pain and tenderness to palpation in the temporomandibular joint (TMJ arthritis) of at least six months duration, and who had not responded to conservative treatment. The two drugs were randomly allocated to the patients. The drugs, 0.5 ml, were injected twice into the superior joint compartment of the TMJ with a two-week interval between injections. ⋯ At the one and two-year follow-ups both the hyaluronate-and the corticosteroid-group had significantly reduced subjective symptoms as well as clinical signs, and the maximum voluntary bite force was significantly increased. The differences in effect between treatments were not statistically significant. It was concluded that both drugs have a significant long-term effect on chronic arthritis of the TMJ and that either of the drugs can be helpful; however, sodium hyaluronate might be the best alternative due to the least risk for side effects.

Case ReportsProblems in evaluation of penetrating foreign bodies with computed tomography scans: report of cases.
Computed tomography is the best radiologic modality available in the evaluation of penetrating injuries to the soft tissues. The technique is the best available when the foreign body has a density similar to the surrounding tissues. ⋯ Interpretation of postoperative changes is also difficult. Two cases have been presented to illustrate the advantages, and limitations of CT scanning in penetrating soft tissue trauma.

Comparative StudyA comparison of labetalol, acebutolol, and lidocaine for controlling the cardiovascular responses to endotracheal intubation for oral surgical procedures.
Arterial blood pressure and pulse rate changes following tracheal intubation were studied in 80 patients undergoing oral surgical procedures who received an etomidate/suxamethonium anesthetic induction sequence. Three treatment groups and a control group were used. ⋯ A pre-induction dose of labetalol was found to be more effective than acebutolol and lidocaine in attenuating the pressor response to instrumentation and intubation. Labetalol should prove most useful for those patients at risk from the transient hypertension and tachycardia following instrumentation and intubation.
