[Surgical treatment of retroperitoneal neurogenic tumors in children].

Objective: To evaluate feasibility and advantages of laparoscopic access in children with retroperitoneal neurogenic tumors.

Material And Methods: A comparative analysis of postoperative results was performed in 2 groups of patients with retroperitoneal neurogenic tumors without IDRF risk factors. Different surgical approaches were applied.

[Acute suppurative destructive pneumonias in children].

Their experience with the observation of 1112 children with acute purulent destructive pneumonias allowed the authors to considerably improve the method of complex curative-diagnostic measures which resulted in lower lethality among this critical contingent of patients and better remote results of their treatment.

[Low-frequency ultrasound in the treatment of acute and chronic suppurative diseases of the lungs and pleura in children].

The maximum exposure and regimens of action of the low frequency ultrasound on the lung and pleura tissue were established in experimental studies. The ultrasound energy was used in the clinic for the complex treatment of 139 patients with acute purulent diseases of the lungs and pleura and in 76 children with chronic bronchopulmonary pathology. High therapeutic effects were achieved which suggests the further application of the method to be fairly promising in children surgery.

[Effect of low-frequency ultrasound on the pleura and adjoining lung tissue].

Morphological changes in the pleura and adjacent pulmonary tissue were studied in 50 rabbits exposed to various doses of low-frequency ultrasound. When the exposure did not exceed 20 sec/cm2, no changes in pleural structure were noted. A longer period of exposure was followed by serous effusion.
