Objective: To evaluate effects of subacromial bursa injection with steroid according to dosage and to investigate whether hyaluronidase can reduce steroid dosage.
Methods: Thirty patients with periarticular shoulder disorder were assigned to receive subacromial bursa injection once a week for two consecutive weeks. Ten patients (group A) underwent subacromial bursa injection with triamcinolone 20 mg; another group of ten patients (group B) with hyaluronidase 1,500 IU and triamcinolone 20 mg; and the other ten patients (group C) with triamcinolone 40 mg.
Objective: To investigate the additive effect of sono-guided subacromial bursa injection of hyaluronate with steroid in patients with peri-articular shoulder disorders.
Method: This prospective randomized controlled trial involved 26 patients who had shoulder pain. Group A, consisting of 13 patients, was treated with a sono-guided subacromial bursa injection containing a mixture of 0.
Objective: To investigate the effect of botulinum toxin type A (BTXA) on drooling and the morphologic change of the salivary gland in patients with cerebral palsy.
Method: Eight cerebral palsy patients suffering from severe drooling participated in this study. BTXA was injected into both submandibular and parotid glands under intravenous sedation and with ultrasound guidance (1 unit/gland/kg: maximum 100 units) in an outpatient or inpatient procedure.
