[The classification of the late period in closed spinal trauma]. / O klassifikatsii pozdnego perioda zakrytoi spinal'noi travmy.

154 patients in the late period of closed trauma of spinal cord were followed up, 40 patients were examined by means of MRT method. There was a progredient course of disease in 20.3% of cases, mainly in patients with compression of spinal cord. The main syndromes of the late period of disease, which was usually characterised by progressive course, were limited adhesive process (arachnoiditis) or progressive myelopathy. The latter manifested with myelomalacia, atrophy, cystic spinal cord's degeneration, discirculatory myelopathy. The classification of the late period of spinal trauma was elaborated. It is of essential importance for medical and social rehabilitation of patients.

[Magnetic resonance tomography in the diagnosis of the neurological complications of lumbar osteochondrosis]. / Magnitno-rezonansnaia tomografiia v diagnostike nevrologicheskikh oslozhnenii poiasnichnogo osteokhondroza.

The analysis of results of magnetic resonance tomography was performed in 289 patients with neurological complications of lumbar osteochondrosis. Among such patients radicular and reflectoral syndromes were observed in 184 patients while diskogenic lumbar-sacral radiculomyeloischemias--in 105 ones. The high informativity of the method was demonstrated in visualisation of localisation, direction and sizes of intervertebral disks' hernias at lumbar osteochondrosis as well as in establishment of such factors which predisposed diskogenic radiculomyeloischemias' development.

[Magnetic resonance tomography in spinal cord trauma]. / Magnitno-rezonansnaia tomografiia pri travme spinnogo mozga.

A total of 44 patients with sequelae of spinal injuries in the periods of 2 months to 46 years were studied by X-ray, neurological and NMR techniques and divided into 3 groups: (1) those with open injuries, (2) those with closed injuries concurrent with compression of the spinal marrow and/or roots of the cauda equina; 3) those with closed injuries without compression. It was shown that NMR tomography enabled the status of the vertebral canal and spinal marrow to be assessed and indications for surgical interventions to be specified. Spinal compression may in later periods result in post-traumatic progressive myelopathy appeared as atrophy of the spinal marrow and myelomalacia (with cyst formation in 18% of cases). The syndrome of progressive myelopathy does not generally develop in patients without spinal compression.

[The production of autoantibodies to nerve tissue glycolipid antigens in patients with traumatic spinal cord injuries]. / Produktsiia autoantitel k glikolipidnym antigenam nervnoi tkani u bol'nykh s travmaticheskimi povrezhdeniiami spinnogo mozga.

The production of autoantibodies (AAB) to the specific antigen of myelin-containing components of the nervous tissue galactocerebroside (GalC) was revealed in 117 patients with traumatic injuries to the spinal cord of various severity in periods of 18 months to 46 years after the injury. The degree of nervous system destruction, the type of the course of posttraumatic myelopathy, and the level of production of AAB to GalC were found interrelated. The existence of AAB provides evidence of sensitization of the immune system to nervous tissue antigens in spinal cord injury, while the level of AAB to GalC reflects the activity of the continuing destructive process due to the injuring effect of AAB under conditions of impaired permeability of the blood-brain barrier and shows the desirability of desensitization therapy.

[Nuclear magnetic tomography in the diagnosis of spinal cord cysts]. / Iaderno-magnitnaia tomografiia v diagnostike kist spinnogo mozga.

Magnetic resonance tomography (MRT) was used in examinations of 172 patients with spinal cord abnormalities. Thirty-eight cysts were detected: 25 in syringomyelia, 5 in intramedullary tumors, 4 posttraumatic and 4 postoperational ones. Based on the MRT patterns, two types of syringomyelia were distinguished, the occlusive and idiopathic ones. The size and site of cyst, as shown by the MRT, did not conform to its neurologic symptoms. A characteristic feature of tumorous cysts was a highly intensive signal originating from their contents. Traumatic cysts were detected against the background of diffuse atrophy of the cord. Computer-aided tomography did not give full-value information in such cases and therefore could not be recommended in cases with suspected intramedullary cysts.

[Condition of the ventricular system in the acute period of cerebral contusions (clinico-echoencephalographic correlations)]. / Sostoianie zheludochkovoi sistemy v ostrom periode sotriaseniia golovnogo mozga (kliniko-ékhoéntsefalograficheskie sopostavleniia).

Echoencephalographic data on the ventricular system in 66 patients during the acute period of cerebral concussion are reported. Forty-seven of them showed statistically significant signs of mild intracranial hypertension. Fourteen out of 31 subjects who had a repeated examination prior to discharge from the hospital displayed no improvement in their echoencephalographic parameters. The results obtained have important implications in assessing the duration of inpatient and outpatient treatment, in establishing the cause-and-effect relationship between the morbid state and a given trauma, and in preventing both prolonged temporary disability and general incapacity.
