Randomized Controlled Trial Comparative Study
Intensive insulin therapy versus conventional glycemic control in patients with acute neurological injury: a prospective controlled trial.
To compare intensive insulin therapy to conventional glycemic control in patients with acute neurological injury evaluating neurological outcome and morbimortality. ⋯ A less strict intensive insulin therapy can reduce hypoglycemia and still maintain its benefits.

Comparative Study
Comparison between posterior lumbar fusion with pedicle screws and posterior lumbar interbody fusion with pedicle screws in adult spondylolisthesis.
The purpose of this study was to compare patients with lumbar spondylolisthesis submitted to two different surgical approaches, and evaluate the results and outcomes in both groups. In a two-year period, 60 adult patients with lumbar spondylolisthesis, both isthmic and degenerative, were submitted to surgery at the Biocor Institute, Brazil. All patients were operated on by the same surgeon (FLRD) in a single institution, and the results were analyzed prospectively. ⋯ The PLIF with pedicle screws group presented better clinical outcomes. Group I presented more complications when compared with Group II. Group II presented better results as indicated in the Prolo Economic and Functional Scale.

Botulinum toxin type A (BT-A) has been described as an important strategy to various types of pain such as cervical dystonia, myofascial pain syndrome and headache. Although BT-A efficacy has not been proven in tension type headache, its use in migraine continues controversial. In this open trial, we evaluated the efficacy of BT-A in refractory migraine. ⋯ The most important improvement was observed within 30 days, but pain intensity and frequency of headache had been decreased until the end of three months of follow up. Side effects of BT-A were mild and self limited. We conclude that BT-A seems to be a safe and effective treatment to refractory migraine patients.

Clinical Trial
Does botulinum toxin improve the function of the patient with spasticity after stroke?
Post-stroke spasticity is an important cause of disability in adults, due to muscle hyperactivity, which results in limb stiffness and muscle spasm. The prognosis for these patients depends on several features such as early management and adequate physical therapy to avoid muscle shortening, pain, and their consequences. Although several papers have shown that intramuscular injections of botulinum toxin type A (BT-A) decreases spasticity in post-stroke patients, few authors have demonstrated functional improvement after this therapy. ⋯ All patients showed improvement according to Ashworth modified scale and increase in the range of motion, which were sustained until the 32nd week (p<0.05). The assessment of the first three parameters of the Fulg-Meyer scale and the evaluations of the motor part of the Functional Independence Measure showed statistically improvement until the end of the study. We conclude that proper choice of muscles and individualized doses of BT-A can improve function in selected post-stroke patients.

SUNCT is one of the rarest and least known primary headache disorders. Although its pathogenesis has been partially understood by functional neuroimaging and reports of secondary cases, there is limited understanding of its cause. We report a case of SUNCT in a 54-years-old man, that could not be strictly classified as secondary SUNCT; however, the time lag of pain onset suggests a new theory in which neuroplasticity could be involved in the origin and duration of the pain in SUNCT syndrome.
