Nomenclature of cell-cultivated meat & seafood products.

Cell-cultivated meat and seafood is getting closer to a reality for consumers in the US and around the world. However, regulators are still largely lagging behind on regulating production and labelling of these products. In a large experimental study using a representative US sample (N = 2653), we tested 9 different names for 3 different types of meat and seafood products in terms of their clarity, consumer appeal, and communication of safety and allergenicity.

Neutrophilic Dermatosis in Myelodysplastic Syndrome and Chronic Active Hepatitis C.

In this article, we describe a case of neutrophilic dermatosis of the dorsal hands (NDDH) complicated with myelodysplastic syndrome and chronic active hepatitis C infection. NDDH was first suggested by Galaria et al in 2000. After comparing features of NDDH with Sweet syndrome in terms of encompassing clinical, laboratory, and histological characteristics, it can be concluded that "distributional or localized variant" of Sweet syndrome is classified as NDDH.

Distal scaphoid resection for degenerative arthritis secondary to scaphoid nonunion: a 20-year experience.

Purpose: To evaluate the long-term results of distal scaphoid excision for degenerative arthritis secondary to scaphoid nonunion and compare them with our original results published in 1999.

Methods: Nineteen patients who were treated by distal scaphoid resection arthroplasty from 1987 through 2010 were included. The mean follow-up was 15 years (range, 10-25 y) vs 4 years in the previous study.

Compartment reconstruction for De Quervain's disease.

A new surgical treatment for De Quervain's disease is presented, in which the anatomy and function of the first dorsal compartment is preserved. Our findings in 11 wrists in ten patients revealed complete relief of the pre-operative symptoms in all instances. The advantages of this technique are its ease, its restoration of normal anatomy, and the prevention of tendon prolapse.

Distal scaphoid resection arthroplasty for the treatment of degenerative arthritis secondary to scaphoid nonunion.

Nineteen patients with chronic scaphoid nonunion and associated degenerative arthritis between the distal fragment and the radial styloid were treated by resection of the distal fragment. All patients had a dorsal intercalated segment instability wrist collapse pattern with an average radiolunate angle of -32 degrees and a 10% reduction in the carpal height, both of which changed minimally during the follow-up period. The duration of the nonunion averaged 12 years and the follow-up period averaged 49 months.

The volar plate reconstruction for fracture-dislocation of the proximal interphalangeal joint.

This article discusses the volar plate arthroplasty utilized to resurface the proximal interphalangeal joint, for fracture subluxations involving the lower 60%. The procedure is effective when open reduction and internal fixation are not feasible because of excessive comminution or delay in treatment. The procedure has been used up to 2 years postinjury if certain conditions are met.

Ligament replacement for chronic instability of the ulnar collateral ligament of the metacarpophalangeal joint of the thumb.

Static and dynamic procedures have been described for reconstruction of chronic instability of the ulnar collateral ligament of the thumb metacarpophalangeal joint. This study presents a technique of ligament replacement utilizing a free tendon graft passed through two gouge tracks in the proximal phalanx and one in the metacarpal in a manner that closely approximates normal anatomy. We retrospectively reviewed 26 patients who underwent replacement.

Permissible limits of flexor digitorum profundus tendon advancement--an anatomic study.

Lacerations of the profundus tendon distal to the superficialis insertion can be treated by advancement of the proximal cut end of the tendon to its insertion. In the English-language literature, limits cited for the distance a profundus tendon can be safely advanced vary from 0.75 to 2.

Palmar carpal instability secondary to dislocation of scaphoid and lunate: report of case and review of the literature.

An isolated dislocation of scaphoid and lunate is presented. We believe that this injury was responsible for the later development of a palmar carpal instability pattern. Carpal kinematics and pertinent literature are reviewed to support this belief.

Volar plate arthroplasty of the proximal interphalangeal joint: a review of ten years' experience.

In 10 years 24 patients had a volar plate advancement arthroplasty for acute or chronic fracture dislocations of the proximal interphalangal joint. Seven were done within 6 weeks of injury, 17 at 6 weeks to 2 years following injury. Final ranges of motion averaged 95 degrees for the former and 78 degrees for the latter group.

Complete dislocation of a little finger metacarpal phalangeal joint treated by closed technique.

Complete dorsal dislocation of the metacarpal phalangeal joint almost always requires an open reduction. This case report presents an unusual set of circumstances allowing a closed reduction to be performed. The metacarpal-phalangeal joint of the patients' little finger was reduced before the carpal-metacarpal joint, followed by placement of percutaneous Kirschner wires.
