Review and update on the management of triangular fibrocartilage complex injuries in professional athletes.

Triangular fibrocartilage complex injuries are common in amateur and professional sports. These injuries are mainly caused by acute or chronic repetitive axial loads on the wrist, particularly on the ulnar side and in association with rotations or radial/ulnar deviations. In order to treat professional athletes, a detailed specific knowledge of the pathology is needed.

Trapeziectomy and suspension arthroplasty with the flexor carpi radialis tendon for treatment of trapeziometacarpal osteoarthritis.

Excision of the trapezium is the common step in most arthroplasties for treating trapeziometacarpal arthritis. Trapeziectomy can be supplemented by several techniques intended to stabilize the first metacarpal but none of these has been proven superior. The aim of this study was to verify if a simplified suspension arthroplasty with the flexor carpi radialis (FCR) tendon, requiring only a single short surgical incision, no intraosseous tunnels and no interposition of prosthetic material, yields equal clinical outcomes to more complex techniques and if the clinical outcomes remain stable over the long term.

Neurolysis versus anterior transposition of the ulnar nerve in cubital tunnel syndrome: a 12 years single secondary specialist centre experience.

Background: Various conservative treatments and surgical techniques have been reported in the literature as efficient and feasible measures to treat the cubital tunnel syndrome. However, there has been no consensus on the best management of the syndrome, and uniform standardised guidelines have not yet been accepted or introduced. With our study, we present our experience on the clinical efficacies and outcomes of the surgical techniques of neurolysis alone and neurolysis associated with ulnar nerve anterior transposition at the elbow joint in patients with neuropathic symptoms due to cubital tunnel syndrome.

Antimicrobial triterpenoids from Licania heteromorpha.

Six triterpenoids having a lupane and oleane skeleton were isolated from the leaves and young branches of Licania heteromorpha Bentham var. heteromorpha and were identified as: betulinic acid 1, alphitolic acid 2, 3 beta-O-trans-p-coumaroyl alphitolic acid 3, 3 beta-O-cis-p-coumaroyl alphitolic acid 4, 3 beta-O-trans-p-coumaroyl maslinic acid 5, 3 beta-O-cis-p-coumaroyl maslinic acid 6. The antimicrobial activity of these compounds was evaluated in vitro on clinically isolated microorganisms employing a microdilution method.

Paradoxical effect of neuroleptic drugs on prolactin secretion by rat pituitary cell cultures.

Several antipsychotic drugs reverse the dopamine-induced inhibition of prolactin release by rat pituitary cell cultures. Paradoxically, at high doses and without dopamine, antipsychotic drugs can also inhibit prolactin secretion. The mechanism underlying this phenomenon is unclear.
