order to better characterize the evidently existing relationship between postural changes in AS patients and rasterstereography. CLINICAL REHABILITATION IMPACT Rasterstereography has proved to be a valid tool in monitoring postural changes in AS patients and has shown a strong correlation with clinical evaluations. Therefore, the assessment of postural characteristics using the rasterstereographic system before and after a specific exercise program would be a reliable and valid advice without exposing subjects to high doses of radiations.BACKGROUND As many as 60-80 % of persons with a history of polio myelitis develop new symptoms, such as new or increased muscle weakness, muscle and joint pain, and fatigue several decades later, called post polio syndrome (PPS). This may affect their ability to perform activities of daily living (ADL). It is still unclear if the patient's symptom is getting worse and in that case how much/fast the decline is. AIM The aim of the present study was to evaluate long-term changes in disability in community dwelling patients with prior poliomyelitis, in contact with a polio clinic 14-16 years post their first assessment. DESIGN A cross sectional longitudinal study. POPULATION Fifty two persons recruited from an earlier 4-year follow up participated in the study. METHODS A questionnaire was mailed prior to the visit at the polio clinic. Physical testing was performed by measuring muscle strength, walking speed and handgrip force. RESULTS Overall there was a small change in muscle strength. A significant reduction in the right leg was found for flexion 60° and in dorsal flexion. For the left leg a significant reduction was found for plantar flexion. In the walking tests, a significant reduction was seen for spontaneous walking speed. No significant interaction between decrease in spontaneous walking speed and the variables age, BMI and flexion 60° and dorsal flexion in the right leg was seen. CONCLUSIONS This cross sectional longitudinal study shows small changes in muscle strength and disability. The results may imply that symptoms associated with late effects of polio are not progressing as fast as we had previously thought. CLINICAL REHABILITATION IMPACT When health care professionals meet persons with late effects of polio the knowledge of long-term consequences of deterioration is important. Knowing that the deterioration is not as fast as previously thought, can help us to support the person in having a healthy lifestyle, stay active and encourage to perform adapted physical training.BACKGROUND To show a novel modified technique to perform minimally invasive anterior odontoid screw fixation. METHODS Twenty-nine patients with a mean age of 45 years were treated with a modified percutaneous anterior odontoid screw fixation. All patients were affected by Type II or rostral shallow Type III odontoid fractures. A modified guide tube was used in all these patients, with reduction of soft tissue dissection for percutaneous approach. RESULTS There were no complications related to the modified technique. Good results and optimal screw placement were achieved in 28 out of 29 patients. Only in 1 patient we observed, after mobilization, screw displacement, probably due to severe osteoporosis. CONCLUSIONS In our opinion, this modified percutaneous minimally invasive technique for anterior odontoid screw fixation, along with the use of a soft tissue dilator not fixed to the spine, has not yet been reported in literature and is strongly recommended to reduce invasiveness of odontoid screw placement.BACKGROUND To explore the effect and mechanism of miR-16-5p on neuron apoptosis and inflammatory response induced by spinal cord injury (SCI). read more METHODS Allen's weight-drop method and Basso Bcattie Bresnahan (BBB) rating scale were used to establish SCI rat model and assess locomotor function, respectively. Histopathology of SCI rats and Sham-operated rats was validated by hematoxylin and eosin (H&E) staining. After intravenous injection of miR-16-5p agomir, miR-16-5p antagomir, pcDNA3.1-Apelin-13 or negative controls into SCI rat tails, neuron apoptosis and the expression of miR-16-5p, Apelin-13, apoptotic proteins, inflammatory response-related proteins and ERK1/2 pathway-related protein were detected. Dual luciferase reporter gene assay was applied for identifying the binding between miR-16-5p and Apelin-13. RESULTS SCI rats had locomotor impairment with markedly edema and hemorrhage. Upregulated miR-16-5p expression and downregulated Apelin-13 expression were presented in SCI rats. Intravenous injection of miR-16-5p antagomir or/and pcDNA3.1-Apelin-13 could increase the expression of anti-apoptotic proteins (Bcl-2 and Mcl-1) and p-ERK1/2 expression while decrease the expression of pro-apoptotic proteins (cleaved caspase-3 and Bax) and inflammatory response-related proteins (TNF-α, IL-1β and IL-6). The reverse pattern was shown in rats injected with miR-16-5p agomir. MiR-16-5p targeted Apelin-13. Promotion of miR-16-5p agomir on SCI was attenuated by injection of agomir + pcDNA3.1-Apelin-13. CONCLUSIONS Downregulation of miR-16-5p could upregulate Apelin-13 expression to activate ERK1/2 pathway, thus alleviating SCI-induced neuron apoptosis and inflammatory response.BACKGROUND Trans-sphenoidal endoscopic surgery has drawn huge benefits from advances in surgical visualization. The Ultra-HD "4K" endoscope has improved 4-fold image resolution compared with HD, but its actual advantages are unclear. Aim of the present study was to assess its usefulness in the early outcome of trans-sphenoidal surgery. METHODS We analyzed a series of 199 trans-sphenoidal pituitary adenoma procedures performed by an experienced team using alternatively HD (n=102) or 4K (n=97) endoscopes. We evaluated extent of resection both subjectively, based on intraoperative surgeon's impression, and objectively based on post-operative MR scan. RESULTS Baseline patients' characteristics were balanced. Objective near-total and total resection rates were comparable between 4K and HD groups (91.5% vs 86.3% and 64.9% vs 56.9%, respectively). 4K endoscope slightly improved resection rate in recurrent adenoma. At multivariate analysis, the only independent prognosticator of total resection was cavernous sinus invasion.
