RESUMO
BACKGROUND: Zinc is one of the most important elements for human body. Zinc deficiency can occur in any age, if it is seen in elderly its clinical results can be more harmful due to already diminished functions. Some studies showed zinc deficiency has an important role in the pathogenesis of Alzheimer disease. In this study we measured the nail zinc levels and aimed to show its clinical implications in geriatric patients, especially Alzheimer disease. PATIENTS AND METHODS: 43 patients with Alzheimer disease and 89 patients with normal cognitive function were evaluated. The diagnosis of Alzheimer disease was made according to DSM-IV and NINCDS-ADRDA criteria after cognitive assessment and neuroimaging performed using magnetic resonance. Hand fingernail samples are obtained from the patients. RESULTS: Mean zinc level from fingernail samples was 117.99 ± 73.44 ppm in Alzheimer Disease patients, 123.86 ± 77.98 ppm in control group (p: 0.680). CONCLUSIONS: This is the first study measuring nail zinc levels in elderly patients with and without Alzheimer disease. Our data reveal no significant difference in nail zinc levels between two groups. However, fingernail zinc may be a useful biomarker in elderly population.

Sudden paraplegia secondary to the posterior spinal epidural compression and vertebral compression fracture as a complication in corticosteroid treatment is extremely rare. The authors presented a case 49-year-old man with chronic relapsing attack of Still's disease. After the identification of pathology, the surgical evacuation of lipid tissue and pedicle-based instrumentation showed therapeutic success. To the authors' knowledge, this is the first case showing both vertebral fracture and paraplegia that required urgent surgery in the follow-up Still's disease.
