RESUMO
Collinear laser spectroscopy was performed on the isomer of the aluminium isotope ^{26m}Al. The measured isotope shift to ^{27}Al in the 3s^{2}3p ^{2}P_{3/2}^{â}â3s^{2}4s ^{2}S_{1/2} atomic transition enabled the first experimental determination of the nuclear charge radius of ^{26m}Al, resulting in R_{c}=3.130(15) fm. This differs by 4.5 standard deviations from the extrapolated value used to calculate the isospin-symmetry breaking corrections in the superallowed ß decay of ^{26m}Al. Its corrected Ft value, important for the estimation of V_{ud} in the Cabibbo-Kobayashi-Maskawa matrix, is thus shifted by 1 standard deviation to 3071.4(1.0) s.
RESUMO
The results of 26 Akin proximal phalangeal osteotomies in 22 patients for hallux valgus deformities are reported. The average follow up was 53 months (range, 12 to 97 months). Subjectively, 16 feet had a satisfactory result (61.5%). Objectively, 14 feet met the criteria for a satisfactory result (53.8%). The authors found that the Akin osteotomy was unpredictable as an isolated procedure, and not indicated in a hallux valgus deformity with an incongruent joint.

Inflammatory processes and ruptures involving the tendons of the foot and ankle are more common than is generally believed. The Achilles and posterior tibial tendons are most commonly involved. Less often, the site of dysfunction is the peroneal tendons. Rupture of the Achilles tendon and dysfunction of the posterior tibial tendon should be readily diagnosed because the history, symptoms, and signs are characteristic. Rupture of the peroneal tendons is rare, and dislocation cannot be diagnosed with certainty unless it is seen promptly or can be reproduced on examination. Treatment of any of these conditions may be operative or nonoperative.

Two cases of gout with marked ulnar deviation (UD) are reported. Both cases were previously diagnosed rheumatoid arthritis (RA) at referral, but gout was clinically suspected because of atypical features of RA, and subsequently confirmed by demonstration of monosodium urate crystals under the polarized microscope. No definitive evidence of associated RA was present in either case. Although UD in gout is distinctly rare, it is important to recognize this deformity in gout in order to avoid inappropriate therapy. Mechanical factors might have contributed to the hand deformities in both cases.
