Decompressive hemicraniectomy (DC) can save the lives of patients with malignant middle cerebral artery (MCA) infarction. We proposed that postoperative midline shift is important for the long-term outcome of patients with MCA infarction. We conducted a retrospective study of DC in 38 patients with malignant MCA infarction. ⋯ Patients who had midline shift less than the optimal diagnostic cut-off point on the fourth postoperative day were classified as having a successful decompression and the remaining patients were classified in the failed decompression group. The successful decompression group mRS score was 4.20±0.89 one year after surgery and the failed decompression group mRS score was 5.11±0.76 (p<0.0001). Successful decompression, resulting in postoperative midline shift of less than 5mm, was a key factor for beneficial, long-term functional outcomes in patients with malignant MCA infarction.

Comparative Study
Volumetric comparisons of supratentorial white matter hyperintensities on FLAIR MRI in patients with migraine and multiple sclerosis.
Migraine and multiple sclerosis (MS) can both cause white matter lesions that appear similar on conventional MRI. This study aimed to compare these abnormalities, and to find anatomical biomarkers specific for migraine. ⋯ Most of the MS WMH were in the frontal lobe and were the smallest average size, while the fewest WMH with the largest size were in the occipital lobe. The pattern of supratentorial WMH appearance differs between the two groups; however, accurate differential diagnosis of WMH by conventional MRI is probably not possible in individual patients.

Comparative Study
Comparison of unilateral versus bilateral balloon kyphoplasty for the treatment of osteoporotic vertebral compression fractures.
Thirty-one patients with osteoporotic vertebral compression fractures (OVCF) were treated with unilateral balloon kyphoplasty (BKP), and 31 patients were treated with bilateral BKP. The efficacy of unilateral and bilateral BKP was assessed by comparing operation time, X-ray exposure times, incidence of complications, vertebral height restoration, and improvement of the visual analogue scale (VAS) scores. ⋯ Unilateral and bilateral BKP are safe and effective treatments for OVCF. Compared with bilateral BKP, patients undergoing unilateral BKP have shorter operations and receive lower X-ray radiation doses.

Intensive insulin therapy (IIT), targeting blood glucose between 80 mg/dL and 110 mg/dL ("strict IIT"), has been associated with rapid remission of high intracranial pressure (ICP), but its use is limited due to a high risk of hypoglycemia. The aim of this retrospective study was to assess whether "moderate IIT" (target range for blood glucose: 80-140 mg/dL) could have the same beneficial effect on ICP with a lower risk of hypoglycemia. We retrospectively analyzed the records of 64 patients with high ICP due to vascular or infectious central nervous system diseases. ⋯ The risk of hypoglycemic events (<40 mg/dL) did not differ significantly between the groups (0 vs. 1 patient, p=0.5). Moderate IIT is associated with remission of high ICP. In contrast to strict IIT, its use seems not to be limited by an increased risk of severe hypoglycemia.

To assess whether idiopathic restless legs syndrome (RLS) is associated with small fiber abnormalities, we evaluated somatic and autonomic small fiber function in 56 patients with idiopathic RLS and 36 age-matched and sex-matched healthy controls using quantitative sensory testing and quantitative sudomotor axon reflex tests. The warm detection thresholds (WDT) of the hands (p=0.017) and feet (p=0.008) were higher in patients with RLS than in controls. ⋯ There were no significant between-group differences in total sweat volume and sweat production in the forearms, proximal legs, distal legs, and feet (p>0.1 each). These findings suggest that abnormal sensory perception in patients with idiopathic RLS may result from impairment of central somatosensory processing rather than small fiber neuropathy.
