[Intraductal radiofrequency ablation under endosonography and cholangioscopy for residual adenoma of the major duodenal papilla with intraductal component].

All adenomas of the major duodenal papilla (MDP) require resection regardless of morphological structure due to high risk of malignancy. Currently, intraluminal endoscopic interventions are preferable for these adenomas. MDP neoplasms with intraductal spread (type III and IV) are of particular difficulty for endoscopic techniques.

[Diagnosis and surgical treatment of a patient with Castleman disease].

Castleman disease (CD) is a benign lymphoproliferative disease. Small prevalence and diverse clinical course of disease makes it difficult to standardize diagnostics and treatment. Currently, the number of CD patients has increased with improvement in the quality of examination.

Fetal diastematomyelia associated with vertebral malformation: ultrasound, MRI, and pathomorphological findings.

Using a specific clinical example, we demonstrate the ability of prenatal magnetic resonance imaging (MRI) to diagnose associated spine and spinal cord malformations in the group of spinal dysraphisms. Thus, the original ultrasound (US) and MRI results for the affected fetus at week 21 are illustrated and described in detail. The paucity of reports of prenatal MR-semiotic findings of split cord malformation comparing US and pathomorphological findings at a relatively early gestational age makes the present case unique and instructive.

[Contact-free determination of the degree of blood filling of human organs and parts of the body at different depths in local regions].

By using the Eddy current rheograph one can measure the level of the blood supply to human organs or body parts at three different depths in local zones as well as study the blood flow in organs in the course of surgery and in the early postsurgical period directly from the area of surgical intervention. Measurements may be performed when applying the unit on dressing and bandages.

[Electroureterograph and dynamoureterograph].

The results of investigations made by the authors showed that the signal spectra of the bioelectrical and mechanical activity of the ureteral smooth muscles lie within the range of 0.05--1 Hz. The developed devices for registration of electro-and dynamograms of ureters may be utilized in investigating the functional state of the urinary system of the organism.
