[Visual illusions and moving horizon].

Results of psychological "additional investigation" of the crash of Boeing-737, "Aeroflot-Nord" on 14.09.2008 near Perm are presented. 37 pilots from the one of the leading airline companies sensed the attitude and rolling out the aircraft to the forward flight under the moving horizon with straight display of bank and tangage (view from the aircraft to the ground) in model conditions. 29 pilots (78.4%) made a mistake at determining the roll direction and tangage, they made a mistake at determining the roll direction 61 times (16.4%) and 44 times at determining the tangage direction, in other words they confused left and right bank and also nose-up and nose-down. Visual illusions of mobility of space and handling of ground (instead of aircraft) during the flight were revealed in pilots. These illusions may be the important cause of the following crashes. The necessity of "back" faultless display of bank in all aircrafts of civil aviation and development of computer complex for training of visual spatial orientation is proved.

[Peculiarities of research of flying thinking].

New approach to the research of flying thinking is offered. This approach is based on principals of stage-by-stage approach (research of the reflection of every parameter of flight, than its aggregate in figured and conceptual framework), on the usage of the methods of registration of inner and external characteristics of activity of the air staff with the priority of research of content area and mechanisms of flying thinking, typology of content area and mechanisms of flying thinking. This approach is also based on the effectiveness of reflection by means of correlation of the detected figured and conceptual framework with time and correctness of decisions of test flight tasks and with different psychophysiological characteristics.

[About spatial orientation of flying staff in air].

Were learned peculiarities of spatial orientation by altitude of pilots and students in conditions of flying over a sea and on link trainer Yak-40, were educed psychophysiological and psychological mechanisms of perception of altitude. Was effectuated a valuation of existing and possible methods of teaching of effective orientation in air. Was shown, that pilots with different professional rate make faults as well in visual flying as visual detecting of the altitude. Were made conclusions about necessity of creation of methods of teaching of effective spatial orientation on the base of altitude, creation of procedure simulator with using of computer technologies for teaching not only students, but flying staff also.

[The predictors of ischemic stroke in cerebral atherosclerosis and ischemic heart disease].

The complex medical examination was performed in 145 patients admitted to the neurological department with initial diagnosis: "ischemic stroke". We compared anamnesis, clinical symptoms, laboratory and instrumental findings in the patients with verified ischemic stroke and in those without stroke. The significant clinical predictors of ischemic stroke were the following: arterial hypertension (> 165/ 95 mm Hg) age 64 years and older, circulatory insufficiency, diabetes, atrial fibrillation, lower extremity obliterating atherosclerosis, pneumosclerosis and pulmonary emphizema.

[Peculiarities of nervous system lesions in patients with multiple myeloma]. / Osobennosti porazheniia nervnoi sistemy u bol'nykh mnozhestvennoi mielomoi.

Multiple myeloma (MM) is B-cellular lymphoproliferative disease. We studied 174 patients aged 33-84 with established diagnosis of MM. Among the persons included into analyzed cohort the data about the presence of polyneuropathy at the moment of MM verification were available in 72 (41.4%) persons. Spinal cord involvement due to the various pathogenetic reasons was revealed in 24 (13.8 +/- 2.6%) patients. Compressional alteration was observed in 19 cases and in 5 patients the spinal cord involvement had uncompressional genesis. The connection between the peripheral polyneuropathy and the unfavourable prognosis in MM patients was statistically insignificant. In the patients with spinal cord prelum the probability of lethal outcome within 1 month was 0.26. It is 10 times more than in patients suffering only from peripheral polyneuropathy. Thus polyneuropathy in MM patients occurs in 41.4 +/- 3.7% cases and more often during the III stage of disease. There is a distinct interrelation between the nervous trunk involvement and disease severity. In the structure of polyneuropathy the sensorimotor variant (76.4 +/- 5.0%) prevails. According to our data the spinal cord involvement occurs in 13.8 +/- 2.6% cases.

[Neurological complications of infectious endocarditis]. / Nevrologicheskie oslozhneniia infektsionnogo éndokardita.

Of 204 patients with infectious endocarditis (IE) treated in the hospital in 1980-2000, 43(21.2%) developed neurological complications. These were: ischemic stroke (72.1%), hemorrhagic stroke (9.3%), both (7%), abscess and subarachnoidal hemorrhage (2.3% for each), meningitis (7%), toxic encephalopathy (11.6%). Neurological complications of IE arose prior to treatment and within the first week of antibacterial therapy in 63% cases, more frequently in the left carotid territory. Neurological complications in IE debute manifested acutely, pareses were more frequent than paralyses, with elevated temperature, low hemoglobin and red cell levels, leukocytosis. MRT detected 8 +/- 4.6 foci in the brain, CT--2 +/- 1.1, on the average. Lethality of IE patients with neurological complications reached 58.1% and was significantly higher than in those without such complications (14.9%, p < 0.001). Overall acturial survival 1 year after the discharge from the hospital was 94.4%, 5-year survival--61.1%, 10-year survival--11%.

Association between allergy and anxiety disorders in youth.

OBJECTIVE: Studies have documented associations between anxiety disorders and allergy in adults, but these associations have not been studied extensively in children. The objective of this study is to examine the associations between allergy and six anxiety disorders (AD) in youth. METHOD: This is a data analysis of two epidemiologic-services studies: (i) alternative service use patterns of youth with serious emotional disturbance (n = 936), and (ii) methods for the epidemiology of child and adolescent mental disorders (n = 1285). Child psychiatric diagnoses were measured by the diagnostic interview schedule for children. Allergy was assessed by the service utilization and risk factors interview. RESULTS: Among ADs, the strongest association found was between allergy and panic disorder (adjusted odds ratio 5.0; p < or = 0.001). Associations of allergy and the other ADs do not seem to be clinically significant. CONCLUSIONS: Findings suggest that in some patients panic disorder may be associated with hypersensitivity of immune system. Panic disorder should be considered in anxious children reporting allergy when no organic cause of allergy is found, and likewise allergy should considered in children with panic disorder.

Seasonal variations in internalizing, externalizing, and substance use disorders in youth.

Seasonal variations were assessed in symptoms of internalizing (anxiety and mood), externalizing (attention-deficit/hyperactivity and oppositional defiant disorders), and substance use disorders in youth. This study is based on secondary data analysis of two NIMH-funded epidemiologic-services studies: (a) Alternative Service Use Patterns by Youth with Serious Emotional Disturbance (N=936, ages 9-17); and (b) Methods for the Epidemiology of Child and Adolescent Mental Disorders (N=1285, ages 9-17). Child psychiatric diagnoses were measured by the Diagnostic Interview Schedule for Children. Variables that indicate site of the interview and service system, as well as age, gender, and ethnicity, were used as covariates. Significant annual variations were found in symptom counts of overanxious disorder, obsessive-compulsive disorder, separation anxiety disorder, social phobia, and major depressive disorder, with the estimated nadir in August-October. There may be weak seasonal variations in attention-deficit/hyperactivity disorder with estimated nadir in August, oppositional defiant disorder with estimated nadir in August-September, and marijuana use with estimated zenith in August-September. Significant seasonality in alcohol, other substance use, agoraphobia, and panic disorder was not found. There may be an instrument-specific bias in estimated nadir. Real nadirs may be up to 3 months prior to the estimated nadirs specified above. Findings suggest that seasonality in symptoms should be considered when assessment instruments of childhood psychiatric disorders are developed, as well as when epidemiological and clinical data are collected and analyzed.

[The role of arterial hypertension in the occurrence of strokes at a young age]. / Rol' arterial'noi gipertenzii v vozniknovenii insul'tov v molodom vozraste.

The analysis of insult occurrence in patients at the age under 45 years, caused by blood hypertension, shows, that they make 30.1% from common number of insult in 166 young people, treated in the neurological and other departments of Burdenko Main Military Clinical Hospital in 1989-1996. On occasion of ischemic insult were treated 37 patients, hemorrhagic--13. The reason of insults was "soft" blood hypertension: in 51.4%--at ischemic insult and in 30.1%--hemorrhagic. The authors consider, that the main direction of prophylaxis of insult is active revealing and adequate treatment of the patients with blood, including "soft" hypertension, use of hypotensive preparations and some non-medicative methods of treatment.
