Chronic migraine is a neurological disorder characterized by 15 or more headache days per month of which at least 8 days show typical migraine features. The process that describes the development from episodic migraine into chronic migraine is commonly referred to as migraine transformation or chronification.

[Correlation of clinico-neurological peculiarities and morphological signs of small hernias (protrusion) of the lumbar intervertebral discs in formation of discogenic pain syndromes in patients of different age].

Morphological signs of small hernias (protrusion) of intervertebral discs (IVD), the results of a neurovisualizing methods of investigation and clinico-neurological features of osteochondrosis as well, were summarized. In young and middle age patients morphological chatacteristics of small hernias (protrusion) of IVD, data of neurovisualizing methods of investigation have had correlated with clinico-neurological features of the disease and were the key determinants while performance of the puncture laser microdiscectomy. In a middle age and elderly patients a weak correlation was noted between the IVD protrusion dimensions and intensity of a lumbar and radicular pain syndromes, functional activity (Osvestry index), what have had permitted to apply a pathogenetically substantiated method of a durable epidural pharmacotherapy.

[The first experience with the use of catheter denervation of renal arteries in patients with refractory hypertension].

The prevalence of refractory arterial hypertension in Russia is estimated at 15%. We report the first experience with surgical treatment of this pathology. The method is based on the reduction of activity of the sympathetic nervous system by selective breaking of connections between of neurons with the help of interventional intravascular radiowave ablation.

[Nutritional support in the treatment of gastric cancer].

The investigation involved 307 patients operated on for gastric adenocarcinoma. Nutritional support was given enterally (50), parenterally (98) and by standard methods (159). Enteral nutrition should be recommended because it was followed by relatively higher total protein and serum albumin levels.

[Percutaneous laser diskectomy in cervical osteochondrosis].

The paper presents early and late outcomes of treatment in 62 patients undergone paracentetic laser "diskectomy" for discogenic compressed syndromes of the neck. It shows the efficiency of surgery for radicular (92.9%) and myelopathic (92.
