Paraplegia due to missed thoracic meningioma after lumbar spinal decompression surgery: A case report and review of the literature

Spinal meningiomas are often localized to the thoracic level and symptoms from a spinal meningioma are determined by the location of the mass. We present a case of thoracic paraplegia due to a thoracic spinal cord tumor (meningioma) that was not detected during lumbar spinal decompressive surgery. Thoracic mass was detected in level of T2-3 on magnetic resonance imaging (MRI). The patient was re-operated and the patient's neurologic symptoms were partially relieved. Surgeons should know that a thoracic silent meningioma can aggrevate neurological symptoms after lumbar spinal decompression surgery and should inform their patient before surgery

Serum Prolidase Activity in Ankylosing Spondylitis and Rheumatoid Arthritis

The aim of the present study was to emphasize the collagen turnover in 2 of the most common chronic inflammatory rheumatic diseases by evaluating serum prolidase activity (SPA) in ankylosing spondylitis (AS) and rheumatoid arthritis (RA). 30 patients who met the modified New York Criteria for the classification of AS, 29 patients who met the 2010 Rheumatoid Arthritis Classification Criteria for the classification of RA, and 31 healthy controls were enrolled in the study. Serum samples of the patients and the controls were collected and SPA was measured by a spectrophotometric method. The comparison of the SPA in these 3 groups was statistically examined. In both patient groups, the SPA was lower than in the control group. SPA in patients with AS was statistically significantly lower than in the control and RA groups ( P < 0.001/ P = 0.002). No statistically significant difference was found between the RA and the control groups ( P = 0.891). In conclusion, lower SPA is presumably associated with decreased collagen turnover and fibrosis, leading to decreased physical functions in both chronic inflammatory musculoskeletal diseases
