INDICATORS OF AXIAL SECTION AREA AND SPLEEN VOLUME IN CHILDREN AND ADOLESCENTS ACCORDING TO INTRAVITAL IMAGING

Abstract The clinical presentation, radiological features, and results of surgical treatment were analyzed in 17 cases of hydrosyringomyelia associated with a Chiari malformation, in children and adolescents younger than 20 years of age. The initial symptoms were a skeletal abnormality (71%), such as scoliosis (11 patients) or pes cavus (1 patient), pain or numbness (24%), and motor weakness (6%). Frequently seen signs on admission were sensory deficit (100%), scoliosis (85%), muscle weakness (64%), muscle atrophy (35%), and lower cranial nerve palsy (35%), The characteristic neurological findings were unilateral sensory and motor deficits (65%) with decreased or absent deep tendon reflexes on the same side. The localization of the syrinx on the axial section varied according to the level, even in the same patient. In 11 patients with unilateral sensory disturbances or unilateral sensory and motor deficits, the syrinx was located in the region corresponding to the posterolateral portion on the same side as that of sensory disturbance at the cervical or thoracic level. On the other hand, in 6 patients with bilateral sensory and motor deficits, the syrinx was located in the central portion and extended into the posterolateral portion of the more affected side. A syringosubarachnoid shunt was placed in 16 patients, foramen magnum decompression without closure of the obex was performed in 1 patient, ventriculoperitoneal shunt in 1 patient, terminal syringostomy in 1 patient, and foramen magnum decompression with terminal syringostomy in 1 patient. In 15 of 17 patients (88%), the neurological symptoms improved after an average follow-up of 4 years and 1 month. We think that as a surgical treatment, placement of a syringosubarachnoid shunt is effective.

Objective: to establish age and gender patterns of changes in the ratio of spleen height to left kidney height in children and adolescents of Orenburg region according to the data of intravital imaging. Materials and methods. Abdominal CT scans of 75 children without visible pathology were examined. The surveyed were divided into 4 age groups: early childhood, first childhood, second childhood, adolescence. The study was performed on 16-slice computed tomographs with the determination of the height of the spleen and the left kidney and calculation of the ratio of these parameters. The obtained data were subjected to variation-statistical processing with the determination of the mean value (M), standard error (m) and the reliability of differences according to the Student's t-test. Results. It was found that the indicator of the height of the spleen among all the examined changed from 7.1±0.3 cm in the 1st group to 10.2±0.3 cm in the 4th group (p=0.001). The height of the left kidney in the 1st group was 7.6±0.1 cm and increased by the 4th group to 10.2±0.1 cm (p=0.001). The smallest value of the ratio of the height of the spleen to the height of the left kidney among girls and boys was found in children of early childhood and was 0.90±0.10 and 0.93±0.04. The maximum value of the indicator among girls was 1.05±0.08 in children of the second childhood, and among boys, 1.05±0.07 in children of first childhood. Conclusion. There are no significant differences between the indicators of the ratio of spleen height to left kidney height, depending on age, and there are no gender differences within the group.

The aimof the study is to establish age and gender patterns of morphometric parameters of the gallbladder in children and adolescents based on the findings of intravital imaging.Material and methods.The authors analyzed computed tomograms of the abdominal cavity of 75 children having no visible pathologies of the abdominal organs. The participants were divided into 4 agegroups: early childhood, first childhood, second childhood, adolescence. The diagnostic procedure was performed on 16-slice computed tomographs; a longitudinal size, a distance between the right and left walls, a distance between the anterior and posterior walls and a volume of the gallbladder were detected in the study. The data obtained were processed using variational and statistical methods,the mean value (M), standard error (m) and the significance of differences according to the Student's t-test were determined.Results.The longitudinal size of the gallbladder averaged 4.5±0.1 cm in the entire sample, 4.3±0.1 cm in girls, and 4.6±0.1 cm in boys; there was detected an increase from 3.7±0.2 cm in group 1 to 4.8±0.3 cm in group 4 (p=0.023). The transverse size of the gallbladder was 1.8 ± 0.1 cm, while in girls -1.8 ± 0.1 cm, and in boys - 1.7 ± 0.1 cm. The value of this parameter increased in all examined children from 1.3 ± 0.1 cm in group 1 to 2.1 ± 0.1 cm in group 4 (p = 0.001). In patients of all groups the average value of the distance between the anterior and posterior walls of the gallbladder was 2.8±0.1 cm. In girls this parameter was 2.8±0.1 cm, and in boys -2.9±0.1 cm. This parameter increased in all patients from 2.4±0.1 cm in group 1 to 3.4±0.1 cm in group 4 (p=0.001). The volume of the gallbladder constituted 13.6±0.8 cm3, in girls this parameter was 12.8±1.0 cm3, and in boys - 14.2±1.3 cm3. The volume of the gallbladder increased in all patients from 7.3±1.1 cm3 in group 1 to 19.4±1.9 cm 3 in group 4 (p=0.001).Conclusion.The most significant increase in most studied parameters (p≤0.05) was noted in children of the first childhood group compared with children of the early childhood group, and in adolescents co mpared with children from the second childhood group without differentiation by gender. A significant increase in the morphometric parameters of the gallbladder was determined mainly in boys of the first childhood group compared with children of the early childhood group and in adolescents compared with children of the second childhood group. In girls there was observed a tendency to a smooth increase in parameters from group to group; a significant increase was determined by the parameter “the distance between the anterior and posterior walls” in children of the second age group compared with children of the first age group (p=0.022). Most of the gallbladder morphometric parameters did not significantly differentiate in girls and boys of the same age group.

Experience Difficulty

Microcomputers offer the potential for increasing the effectiveness of language intervention for school-age children and adolescents who have language-learning disabilities. One promising application is in the treatment of students who experience difficulty comprehending figurative expressions, an aspect of language that occurs frequently in both spoken and written contexts. Although software is available to teach figurative language to children and adolescents, it is our feeling that improvements are needed in the existing programs. Software should be reviewed carefully before it is used with students, just as standardized tests and other clinical and educational materials are routinely scrutinized before use. In this article, four microcomputer programs are described and evaluated. Suggestions are then offered for the development of new types of software to teach figurative language.
