Comparison of kyphoplasty and vertebroplasty in the treatment of fresh vertebral compression fractures

Introduction  As life expectancy in the population rises, osteoporotic fractures are seen most frequently in the proximal femur and the vertebral column. In balloon kyphoplasty and vertebroplasty, we have two minimally invasive treatment procedures available. Although they have both been controversially discussed in studies, they have seldom been directly compared. Materials and methods  Between 2002 and 2004, patients with fresh thoracic or lumbar single-segment vertebral compression fractures not involving neurological deficits were treated by balloon kyphoplasty (n = 30) or vertebroplasty(n = 30) using PMMA cement, and the results of the two interventions were compared in a prospective, nonrandomised cohort study. Surgery was indicated when patients had painful, dislocated fractures of type A1 and type A3 according to Magerl’s classification. The outcome of treatment was assessed with special reference to the angle of kyphosis, back pain (VAS), health-related quality of life (SF-36) and complications. Results  At the time of the follow-up examination, significant improvement in the angle of kyphosis was found to have been achieved both by kyphoplasty and by vertebroplasty (P < 0.001 and P = 0.002, respectively). Comparison showed that correction of the angle was significantly (P < 0.001) better in the kyphoplasty group. Both surgical procedures led to significant (P < 0.001) attenuation of the patients’ pain; no difference was observed between the groups in the degree of pain relief achieved. There was no demonstrable correlation in either group between the preoperative pain experienced by the patients and the degree of dislocation of their fractures. In both study groups, the quality of life was in keeping with that of a reference group matched for age and sex. Cement leakage was observed in 7% of patients after kyphoplasty and in 33% of patients after vertebroplasty (P = 0.021). Adjacent-level fractures were checked for, but occurred in only one patient in the vertebroplasty group. Conclusion  The two surgical procedures were both followed by significant pain relief, and the quality of life was similar regardless of the procedure used. Balloon kyphoplasty led to an ongoing reduction of freshly fractured vertebrae and was followed by a lower rate of cement leakage.     

The effect of budesonide mouthwash on oral chronic graft versus host disease

Oral chronic graft versus host disease (cGVHD) is common and a major cause of morbidity and loss of quality of life in long term survivors. Cyclosporine with prednisone remains the first line therapy for oral manifestations of cGVHD. However, even with routine administration of systemic agents, many patients with oral manifestations of cGVHD do not have resolution of their disease and may benefit from incorporation of local therapy. Budesonide is a highly potent steroid which has minimal systemic side effects and being used for oral cGVHD. We designed a retrospective study to compare treatment results of patients with oral cGVHD who received topical budesonide in addition to systemic therapy that consists of combined prednisone and cyclosporine (Group A, n = 12), with the treatment results of patients who were administered the same systemic therapy alone (Group B, n = 11) to determine whether budesonide mouthwash had any advantage on response rates. Three mg topical budesonide/10 ml saline was used 3-4 times a day for up to 6 months in group A. Diagnosis, clinical staging, and treatment response scoring for cGVHD were performed according to National Institutes of Health (NIH) consensus criteria. At the baseline examination, there were no statistically significant differences in terms of median oral cGVHD examination scores between two groups. After treatment, there was statistically significant decrease in median oral cGVHD examination scores compared to baseline (P < 0.001 and 0.021), and significant differences were found between two groups (P < 0.032). Overall response rate was 83% and 36% for group A and B, respectively (P = 0.036). However, no statistically significant differences were found between median pain scores of two groups before and after treatment (P = 0.740 and P = 0.091). No major systemic side effects and oral candidiasis were observed in two groups of patients. We concluded that topical budesonide might be added to systemic therapy to obtain better response rates in patients with oral cGHVD.     

Effects of rheumatoid factor isotypes on disease activity and severity in patients with rheumatoid arthritis: a comparative study

The value of rheumatoid factor (RF) isotypes for assessing rheumatoid arthritis (RA) remains debatable. In this study, we have examined the relationships between RF isotypes and disease activity and severity in RA patients. Sixty-two patients with RA, 48 women and 14 men, were studied. RF was measured by nephelometry (RF–N) and IgG–, IgA–, and IgM–RF isotypes were measured using enzyme-linked immunosorbent assay. Serum C-reactive protein and erythrocyte sedimentation rate were also determined. The patients were classified according to disease activity, joint damage, functional status, and presence of pulmonary involvement, rheumatoid nodule, and secondary Sjögren’s syndrome. Although the patients with active disease had significantly higher IgA–RF and IgM–RF levels compared to inactive patients, IgA–RF and IgM–RF were not found to be independently associated with disease activity in multivariate analysis. In patients with severe joint damage, IgA–RF and RF–N were significantly higher than those of the other patients. Multiple regression analysis showed that IgA–RF was the unique variable independently associated to severe joint damage. The patients with class III and IV functional index had significantly higher IgM–RF, IgA–RF, and RF–N levels compared to the patients with class I and II functional index; however, RFs were not significantly associated with functional status in multivariate analysis. IgA–RF and IgM–RF were significantly associated with pulmonary involvement and rheumatoid nodule, respectively. No significant associations were found between RF isotypes and secondary Sjögren’s syndrome. Our results suggest that the clinical usefulness of IgA and IgM isotypes is better than RF–N. Elevated IgA–RF may be a marker of erosive disease. The usefulness of RF isotypes for monitoring disease activity or functional status appears to be limited.     

Intracranial symptomatic giant arachnoid cyst of the interhemispheric fissure presenting with frontal lobe syndrome

Symptomatic interhemispheric arachnoid cysts (ACs) are extremely rare lesions seen more frequently in the elderly. Only 13 cases of symptomatic interhemispheric ACs in the elderly have previously been reported. Herein, we describe a 70-year-old female with symptoms of vertigo, memory and behavior disturbances. Magnetic resonance imaging (MRI) revealed a giant arachnoid cyst (AC) on the interhemispheric fissure, which was exerting a mass effect and displacement on the corpus callosum and anterior cerebral vessels, with a massive midline shift. The patient was treated with a cysto-peritoneal shunt. Reports to date have reviewed the pathology, clinical presentation, radiology and surgical management of interhemispheric symptomatic arachnoid cysts in elderly patients.
