An association between spinal kyphosis and gastroesophageal reflux disease (GERD) was reported in recent years. However, it remains unclear whether spinal kyphosis affects gastric motility. We evaluated the changes in myoelectrical activity measured by electrogastrography (EGG) in elderly osteoporosis patients. A total of 18 patients scheduled for the treatment of osteoporosis were included in this study. They were analyzed by recording EGG to assess myoelectrical activity and heart rate variability (HRV) to evaluate the autonomic nervous system function before and after meals. Dominant power (DP) representing the strength of gastric electrical activity and dominant frequency (DF) representing its frequency were analyzed in blocks with a 5-minute duration. We divided the patients into 2 groups, thoracolumbar kyphosis (TLK) and non-TLK groups, and compared them. There were no significant differences between the 2 groups in background data. In the non-TLK group, DPs post 0–5 min were significantly higher than those during pre 5–0 min in channels 1 and 3 (P < 0.05 and P < 0.01). DF deviation in the TLK group was significantly higher than that in the non-TLK group at 10 to 15 postprandial minutes (P < 0.05). Low frequency/high frequency activity measured by HRV, reflecting the activity of the sympathetic nervous system, in the TLK group was significantly lower than that in the non-TLK group while eating (P < 0.01). The EGG of patients with spinal kyphotic deformity showed a similar change to that of patients with GERD; the spinal kyphotic deformity itself may affect gastric electrical activity.

Micro-CT imaging analysis for the effects of ibandronate and eldecalcitol osecondary osteoporosis and arthritis in adjuvant-induced arthritis rats

Research paper (journal)

We investigated the effects of ibandronate, a bisphosphonate; eldecalcitol, an active vitamin D3 analogue; and combination treatment with both agents on secondary osteoporosis and arthritis using rats with adjuvant-induced arthritis. Arthritis was induced in 8-week-old male Lewis rats. Rats were randomized into four treatment groups and an untreated normal control group: ibandronate, eldecalcitol, ibandronate + eldecalcitol, vehicle, and control. Paw thickness was measured to evaluate arthritis. Joint destruction was evaluated histomorphometrically by the ankle joint stained with Fast Green and safranin O. The femur and lumbar spine were scanned using dual-energy X-ray absorptiometry, and the distal femur was scanned using micro-computed tomography for bone mineral density (BMD) and trabecular microstructural evaluations. Ibandronate and/or eldecalcitol increased BMD in both the lumbar vertebrae and femur and improved several microstructural parameters (bone volume/total volume, structure model index, trabecular number, and trabecular separation of the distal femur). In addition, there was an additive effect of combination treatment compared with single treatments for most trabecular parameters, including BMD and bone volume. However, ibandronate and/or eldecalcitol did not inhibit arthritis and joint destruction. Combination treatment with ibandronate and eldecalcitol may be effective for secondary osteoporosis associated with arthritis.

INTRODUCTION: C1 lateral mass screws and C2 pedicle screws are usually chosen to fix atlantoaxial (C1-C2) instability. However, there are a few situations in which these screws are difficult to use, such as in a case with a fracture line at the screw insertion point and bleeding from the fracture site. A new technique using a unilateral C1 posterior arch screw and a C2 laminar screw combined with a contralateral C1 lateral mass screws-C2 pedicle screws procedure for upper cervical fixation is reported. CASE REPORT: A 24-year-old woman had an irreducible C1-C2 anterior dislocation with a type III odontoid fracture on the right side due to a traffic accident. The patient underwent open reduction and posterior C1-C2 fixation. On the left side, a C1 lateral mass screws and a C2 pedicle screws were placed. Because there was bleeding from the fracture site and a high-riding vertebral artery was seen on the right side, a C1 posterior arch screw and a C2 laminar screw were chosen. Eight months after the surgery, computed tomography scans showed healing of the odontoid fracture with anatomically correct alignment. CONCLUSIONS: Although there have been few comparable studies, fixation with unilateral C1 posterior arch screw-C2 laminar screw could be a beneficial choice for surgeries involving the upper cervical region in patients with fracture dislocation or arterial abnormalities.
