INTRODUCTION Chronic cough is a common clinical problem and there is a shortage of effective treatments for it. Within the group of transient receptor potential ion channels a receptor for the cooling substance menthol has been identified. This study aimed to assess whether pre-inhalation of dissolved, nebulised menthol could increase capsaicin cough thresholds and influence spirometric values....

BACKGROUND We aimed to determine whether patients with arthroscopically repaired rotator cuff (RC) tears would have reduced pain and improved function after ultrasound-guided platelet-rich plasma (PRP) injections compared with placebo injection. HYPOTHESIS PRP compared with placebo (saline) was more effective in reducing pain at the site of an RC injury that has undergone arthroscopic repair....

This study assessed the efficacy of high-molecular-weight sodium hyaluronate as a treatment for certain intracapsular temporomandibular joint (TMJ) disorders. One hundred twenty-one patients were studied at three test sites using a randomized, double-blind, placebo-controlled experimental design. Patients were selected on the basis of 1) confirmed diagnosis of either degenerative joint disease ...

OBJECTIVE Supraphysiological levels of ghrelin and GH induce insulin resistance. Serum levels of retinol-binding protein-4 (RBP4) correlate inversely with insulin sensitivity in patients with type 2 diabetes. We aimed to determine whether ghrelin and GH affect RBP4 levels in human subjects. MATERIALS AND METHODS To study GH-independent effects of ghrelin, seven hypopituitary men undergoing re...

OBJECTIVE We sought to assess pharmacodynamic responses to the bradykinin antagonist B9340 and to determine the contribution of the endothelial bradykinin receptor to stimulated tissue plasminogen activator (t-PA) release in humans. METHODS AND RESULTS Bilateral forearm blood flow and plasma fibrinolytic variables were measured in 8 volunteers during 100 minutes of intrabrachial infusions of ...

OBJECTIVE To investigate the effect of botulinum toxin A on associated pain and functional impairment of refractory plantar fasciitis. DESIGN This is a randomized, double-blind, placebo-controlled study of 27 patients (43 feet) with plantar fasciitis. Block randomization was performed using computer software. In patients with bilateral symptoms of comparable severity, botulinum toxin A was in...

BACKGROUND Preemptive analgesia is considered an alternative for treating the postsurgical pain of third molar removal. The aim of this study was to evaluate the preemptive analgesic efficacy of oral ketorolac versus intramuscular tramadol after a mandibular third molar surgery. MATERIAL AND METHODS A parallel, double-blind, randomized, placebo-controlled clinical trial was carried out. Thirt...

OBJECTIVE The aim of this study was to compare preemptive analgesia of oral ketorolac plus submucous local placebo with oral ketorolac plus submucous local tramadol after impacted mandibular third molar surgery. STUDY DESIGN A double-blind, randomized, placebo-controlled clinical trial was conducted. Patients were randomized into two treatment groups (n = 15 per group): group A, oral ketorola...

OBJECTIVES Effective analgesia after total knee arthroplasty (TKA) improves patient satisfaction, mobility and expedites discharge. This study assessed whether continuous femoral nerve infusion (CFNI) was superior to a single-shot femoral nerve block in primary TKA surgery completed under subarachnoid blockade including morphine. METHODS We performed an adequately powered, prospective, random...
