Controlling pain has always been one of the biggest challenges of medical science. Despite pharmacological developments, still many patients suffer from long-lasting pain. During the last 40 years several surgical interventions have been used to modulate the activity of the central nervous system in order to control chronic, pharmacoresistant pain. ⋯ In the 90's new techniques of non-invasive brain stimulation have been introduced that enable the facilitation or inhibition of distinct cortical areas. These methods are based on the electrical stimulation of brain structures and to date they have been successfully used to modulate perceptual, cognitive and motor functions in healthy subjects and various diseases as well. In this review we describe such techniques of non-invasive brain stimulation, namely repeated transcranial magnetic stimulation and transcranial direct current stimulation and review the current literature about their efficacy in controlling acute and chronic pain.

The last decade has brought significant development in spine surgery. As in all field of surgery, introduction of the minimal invasive, atraumatic procedures characterized our activities. The number of short and long-time complications were significantly reduced and the effectiveness of operations were markedly improved by the new technical conditions, for example by the use of neuronavigation, surgical microscope, intraoperative fluoroscopy, high speed drill and the widespread of keyhole concept. ⋯ This overview of the minimal invasive techniques can be applied and recommended in the daily routine of spine surgery. We proudly employ novel surgical techniques having been developed in our institution. These techniques are internationally recognized and applied in our practice on daily basis as well.

Clinical Trial
[Effect of two month positive airway pressure therapy on the structure of sleep, cognitive function and anxiety].
Obstructive sleep apnea is a common disorder, characterized by repeated episodes of upper airway obstruction during sleep, resulting intermittent hypoxia and disruption of the normal sleep pattern, which caused cognitive dysfunction in these patients. Nasal continuous positive airway pressure is the treatment of choice for this disorder. The aim of the study is to evaluate the effect of short-term positive airway pressure on sleep pattern (polisomnographic measures), cognitive function and anxiety. ⋯ Despite of treatment we did not find improvement in visuospatial learning. These results reveal that 2 and a half months of positive airway pressure treatment restored not only the normal respiration during sleep and normal sleep pattern, but also the cognitive functions. Our study suggests that cognitive dysfunction is at least partial reversible in obstructive sleep apnea patients after positive airway pressure treatment.
