RESUMO

INTRODUCTION: Fingolimod is an immunomodulating oral treatment used for treating relapsing-remitting multiple sclerosis (RRMS). The exact mechanism for its action in preventing relapses is unknown. Also, its affect on immune cell populations remains unestablished. OBJECTIVES: This study will measure the changes in cell populations of WBCs, lymphocytes, and neutrophils in MS patients after one month of treatment. METHODS: 66 MS patients from Isfahan Province with RRMS were chosen based on certain exclusion criteria and eligibility for fingolimod oral treatment. Initial cell counts for WBC, lymphocyte, and neutrophil cell populations were achieved. Fingolimod .5 mg daily treatment was then initiated under the supervision of a physician. After one month of treatment, cell counts were repeated. Statistical analysis was performed using SPSS. RESULTS: Both lymphocyte and WBC mean cell counts were significantly decreased in this patient cohort. Neutrophil average cell counts were significantly increased in this 66 patient cohort. Only the decrease of WBC populations was significant for both male and female cohorts individually. Only female sub-cohorts were significantly changed for neutrophils and lymphocytes, increased and decreased respectively. Male sub-cohorts maintained the same directionality but failed to produce statistical significance. CONCLUSION: While fingolimod has been effectively proven as reducing lymphocyte cells in most patient populations, its effects on neutrophils have not been studied in abundance. Also, there may be sex-related differences in responses to fingolimod treatment with regards to lymphocytes and neutrophils, suggesting a possible difference in RRMS pathogenesis between males and females.

RESUMO

BACKGROUND: Scoliosis is a sideways curve in the spine. Considering that postoperative complications are common among these patients, the aim of this study is to examine the postoperative complications of posterior fusion surgery with instrumentation among adult patients with idiopathic scoliosis. METHODS: In this cross-sectional descriptive study, the postoperative complications were examined among 93 patients with idiopathic scoliosis who underwent posterior fusion surgery with instrumentation. The convenience sampling was used by referring to the files of these patients. The patients were classified into four groups according to the type of scoliosis deformity (long C-shaped, thoracic, thoracolumbar/lumbar, and double-curve) and the complications were compared together. RESULTS: Postoperative respiratory problems were significantly different between the four groups of scoliosis deformity (P = 0.009); 35 cases of postoperative complications occurred and 20 of them were related to postoperative pulmonary complications. CONCLUSION: Postoperative complications are common among patients with idiopathic scoliosis who underwent posterior fusion surgery with instrumentation; in addition, pulmonary complications are the most common postoperative complication among these patients.
