The purpose of this study was to assess the long-term results (more than ten years) of two types of cemented ulnar component with type-5 Kudo total elbow arthroplasty in a consecutive series of 56 patients (60 elbows) with rheumatoid arthritis, and to compare the results in elbows above and below a Larsen grade IV. There was no radiolucency around the humeral component. Patients in whom a metal...

BACKGROUND There have been no reports on the long-term outcome of radial neck Mason type IIIb fractures in adults. METHODS 3 women and 2 men, aged 46 (22-69) years when they sustained a radial neck Mason type IIIb fracture, were evaluated after an average of 18 (16-21) years. All had been treated with radial head excision. RESULTS 3 individuals had no subjective elbow complaints while 2 rep...

purpose: to assess parameters that had a capability of influencing the rate of big bubble formation during deep anterior lamellar keratoplasty (dalk) in keratoconus. methods: a total of 290 consecutive eyes from 257 patients with keratoconus that underwent dalk using the big-bubble technique were enrolled. the influence of patient age and sex, family history of keratoconus, history of contact l...

Since the adoption of Abney’s (1987) influential proposal that noun phrases are (at most) DPs, the hypothesis that not all noun phrases in all languages are DPs has been widely debated. A particularly interesting case in this respect is presented by Slavic languages lacking overt articles such as Russian or Serbo-Croatian: are noun phrases in such languages ever DPs, always DPs, or sometimes DP...

OBJECTIVE To test a novel hydrogel sealant to secure sutureless sclerotomies under variable intraocular pressure conditions. METHODS In cadaver eyes, 23- and 20-gauge (G) sclerotomies were constructed. Sixteen 23-G beveled sclerotomies were constructed in 4 eyes: 8 of the incisions were treated with hydrogel sealant, while 8 were left bare. All sclerotomies were monitored for leaks while the ...

Genetically determined hypertrichosis is uncommon, but several forms of familial hairiness have been described. In some kindreds the unusual hairiness has been generalized, while in others, the hypertrichosis has been confined to a specific site on the body. The purpose of this paper is to report the occurrence of undue hairiness of the elbow regions in members of an Amish family, and to discus...

Light-driven transcription, replication and enzyme catalysis are critically dependent upon a delicate transfer between molecular and supramolecular chirality. Chemists have well realized the impressive stereospecificity over many thermally accessible cycloaddition with chiral catalysts, but making light work in the enantiomer control of diarylethene photocyclization has proved to be more challe...
