Summary:

Objective: to identify the variability and contingency of parameters characterizing the structure of the hip joint in children 4-7 years of age, among themselves and with the severity of dysplastic changes in the bone and soft tissue structures of the hip joint. Material and Methods. 132 children aged 4-7 years with dysplasia TBS with different degrees of severity of dysplastic changes (177 joints) were examined. The following characteristics of dysplasia joint were under the study: angular radiological parameters, cartilage defect, electroneuromyographic signs, indicators of the biomechanics of gait. The degree of dysplasia (mild, moderate, severe) was assessed by the method developed by the authors to determine the severity of hip dysplastic changes in points. Results. Light changes in the hip joint were diagnosed in 9 patients aged 4-7 years (15 joints); moderate dysplastic disorders were found in 74 patients (96 joints); pronounced signs of dysplasia were found in 49 patients (66 joints). The coefficient of variation of signs characterizing TDS dysplasia varies from 2.8 to 18.8%. The module of correlation coefficients characterizing the binding force of the studied features is in the range from 0.7 to 0.9. Conclusion. The angular radiological parameters, cartilage defect, electroneuromyographic signs, indicators of the biomechanics of gait characterized by considerable variability and are correlated with strong and close power among themselves and with the degree of dysplastic changes of the bone and soft tissue structures of TBS.

Summary:

Objective: to determine the volume and direction of correlations of length of the proximal phalanges of the 2-5th fingers of the hand with osteometric parameters of phalanges of like fingers. Material and Methods. The length of proximal, medium and distal phalanges, as well as the width and height: the bases, body and heads (distal tuberosity) phalanges of fingers of the hand were studied on 150 skeletons of adult men and women hands at the age 21-90 years old. Results. The correlation between the length of proximal phalanges and pulse- high-rise parameters of proximal, medium and distal phalanges of 2-5th fingers of hand was determined. Conclusion. The length of the proximal phalange forms a different strength and direction of the correlation. The lengths of the proximal phalanges have a positive direction of moderate strength with all parameters of middle phalanges and the average degree of correlation with the length of the distal phalanges, the width of its base and the body.

Interdependence of parameters of varia-tional pulsometry, entropy of heart rate, temporal and spectral analyses of heart rate variability in normal state and in ischemic heart disease

Year: 2011, volume 7 Issue: №3 Pages: 607-611
Heading: Internal Diseases Article type: Original article

Organization: Saratov Institute of Cardiology, Russia
Summary:

The research goal is to study the correlation between indices of variational pulsometry, entropy of heart rate, temporal and spectral analyses and heart rate variability in healthy patients and patients with coronary heart disease. Materials. Of the study are indicators of variational pulsometry and temporal and spectral analyses from 111 patients with coronary heart disease and in 61 healthy individuals. Results. Most parameters of HRV correlated with each other. In healthy patients the greatest independence was characterized by Mo and LF/HF, in patients with coronary artery disease — only by LF/HF Significant correlation with SDNN RMSSD, TP, LF, HF was determined. Conclusion. The variational pulsometry, temporal and spectral analyses of HRV and entropy of heart rate provide HRV assessment. The indices are interdependent and indicate interchangeability of methods
