Divergent effects of cannabidiol on the discriminative stimulus and place conditioning effects of Delta(9)-tetrahydrocannabinol.

Cannabis sativa (marijuana plant) contains myriad cannabinoid compounds; yet, investigative attention has focused almost exclusively on Delta(9)-tetrahydrocannabinol (THC), its primary psychoactive substituent. Interest in modulation of THC's effects by these other cannabinoids (e.g.

Extensor mechanism slide for the treatment of proximal interphalangeal joint extension lag: an anatomic study.

Purpose: We describe a technique for correction of proximal interphalangeal joint (PIP) extensor lag secondary to angulation and/or shortening of proximal phalanx fractures.

Methods: Proximal phalanx fracture malunions with 2.5 mm of shortening, 5.

The correction of ulnar claw fingers: a follow-up study comparing the extensor-to-flexor with the palmaris longus 4-tailed tendon transfer in patients with leprosy.

Purpose: The extensor to flexor 4-tailed tendon transfer (EF4T) and the palmaris longus 4-tailed tendon transfer (PL4T) are 2 surgical procedures used to correct intrinsic paralysis of the hand in leprosy. The EF4T traditionally is the more common procedure and requires the transfer of a wrist extensor muscle. The PL4T requires the transfer of the palmaris longus and morbidity is expected to be lower.
