To evaluate characteristics of static and dynamic parameters in patients with degenerative flat back (DFB) and to compare degree of their improvement between successful and unsuccessful surgical outcome groups
Forty-seven patients with DFB were included who took whole spine X-ray and three-dimensional motion analysis before and 6 months after corrective surgery. Forty-four subjects were selected as a control group. As static parameters, thoracic kyphosis (TK), thoracolumbar junction (TLJ), lumbar lordosis (LL), pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT) were measured. As dynamic parameters, maximal and minimal angle of pelvic tilt, lower limb joints, and thoracic and lumbar vertebrae column (dynamic TK and LL) in sagittal plane were obtained.
The DFB group showed smaller TK and larger LL, pelvic posterior tilt, hip flexion, knee flexion, and ankle dorsiflexion than the control group. Most of these parameters were significantly corrected by fusion surgery. Dynamic spinal parameters correlated with static spinal parameters. The successful group obtained significant improvement in maximal and minimal dynamic LL than the unsuccessful group.
The DFB group showed characteristic lower limb and spinal angles in dynamic and static parameters. Correlation between static and dynamic parameters was found in spinal segment. Dynamic LL was good predictor of successful surgical outcomes.

Cerebral hemorrhage is one of the most common causes of dysphagia. In many cases, dysphagia gets better once the acute phase has passed. Structural lesions such as thyromegaly, cervical hyperostosis, congenital web, Zenker's diverticulum, neoplasm, radiation fibrosis, and retropharyngeal abscess must be considered as other causes of dysphagia as well. Retropharyngeal abscess seldom occur in adults and if it does so, a search for a prior dental procedure, trauma, head and neck infection is needed. The symptoms may include neck pain, dysphagia, sore throat, and in rare cases, dyspnea accompanied by stridor. We present a case and discuss a patient who had dysphagia and neck pain after a cerebral hemorrhage. Testing revealed a retropharyngeal abscess. The symptoms were successfully treated after the administration of antibiotics.

To evaluate the relationship between the cross sectional area (CSA) and isokinetic strength of the back muscles in patients with chronic low back pain.
Data of twenty-eight middle-aged patients with chronic back pain were analyzed retrospectively. CSAs of both paraspinal muscles and the disc at the L4-L5 level were measured in MRI axial images and the relative CSAs (rCSA: CSA ratio of muscle and disc) were calculated. The degree of paraspinal muscle atrophy was rated qualitatively. Isokinetic strengths (peak torque, peak torque per body weight) of back flexor and extensor were measured with the isokinetic testing machine. Multiple regression analysis with backward elimination was used to evaluate relations between isokinetic strength and various factors, such as CSA or rCSA and clinical characteristics in all patients. The same analysis was repeated in the female patients.
In analysis with CSA and clinical characteristics, body mass index (BMI) and CSA were significant influencing factors in the peak torque of the back flexor muscles. CSA was a significant influencing factor in the peak torque of total back muscles. In analysis with rCSA and clinical characteristics, BMI was significant in influencing the peak torque of the back flexors. In female patients, rCSA was a significant influencing factor in the peak torque per body weight of the back flexors, and age and BMI were influencing factors in the peak torque of back flexors and total back muscles.
In middle-aged patients with chronic low back pain, CSA and rCSA were influencing factors in the strength of total back muscles and back flexors. Also, gender and BMI were influencing factors.

Ramsay-Hunt syndrome is caused by varicella zoster virus infection in the geniculate ganglion of the facial nerve. It is characterized by facial palsy, otic pain, and herpetic vesicles around the auricle and external auditory canal. Additionally, symptoms may develop related to other cranial nerve involvement, such as dizziness or hearing loss by the vestibulocochlear nerve being invaded. We report a rare case of a Ramsay-Hunt syndrome patient who developed dysphagia due to multiple cranial nerve involvement including the glossopharyngeal nerve and vagus nerve.
