RESUMO
A 36-year-old woman presented with lower extremity paralysis. Her past medical history included gout. Conventional radiography and MR imaging revealed bone erosion and soft tissue lesions of the thoracic spine. Fluorodeoxyglucose-positron-emission tomographic (FDG-PET) images revealed hypermetabolic lesions of the thoracic spine. A CT-guided biopsy was diagnostic for inflammatory tophaceous gout. This case describes the CT, MR, and FDG-PET imaging characteristics of acute inflammatory gout. FDG-PET imaging characteristics of this disorder have not been previously described.

We believe that the extended SMAS technique may be useful in selected facial cleft patients. In three Treacher Collins patients, this technique produced a modest improvement in the quantity and quality of the malar soft tissue that had not been achieved after orbitozygomatic or maxillomandibular surgery.

Unhappy with our postoperative results from standard tongue reduction methods, we have developed a central tongue reduction technique. This technique allows for alteration of the tongue base as well as tongue height and width while minimizing postoperative scarring. Although the technique and its associated surgical complications are in some ways comparable with the standard tongue reduction methods, our postoperative polysomnographic and tongue functioning results are improved. It is noteworthy that none of our patients had worse speech postoperatively and that our one Down syndrome patient had improved speech. Our indication for central tongue reduction is macroglossia of any sort in appropriate patients.

Amputation of a forepaw digit in raccoons 2-8 weeks of age produced dramatic changes in the functional organization of somatosensory cortex examined electrophysiologically 9-12 months later. The cortical region normally representing the digit that was amputated received widely overlapping input from the entire forepaw, with local disruption of somatotopic organization. Compared with normal animals, the receptive fields of cortical neurons in amputated animals were larger, often included both glabrous and hairy skin, sometimes involved discontinuous skin regions, and were much more variable in peripheral location as a function of recording distance across the cortex and of depth within the cortex.
