[The capacities of ultrasound study and magnetic resonance imaging of small pelvic masses after hysterectomy].

The purpose of the study was to develop the ultrasound study (USS) and magnetic resonance imaging (MRI) semiotics of small pelvic masses after hysterectomy, to comprehensively use USS and MRI for the diagnosis of these masses, and to define indications for MRI. One hundred and seventy-five female patients with small pelvic masses after hysterectomy were examined. For the specification of the pattern of small pelvic masses and their differential diagnosis, USS and MRI were carried out in 175 and 72 patients, respectively. Four groups of the masses were identified; of them there were tumor-like masses of the uterine appendages in 67 (38.2%) patients, ovarian tumors in 31 (17.7%), other additional masses of the small pelvis in 27 (15.4%), and a mixed variant of its masses in 50 (28.5%). The findings suggest that it is reasonable to concurrently use USS and MRI in the diagnosis of small pelvic masses following hysterectomy for the specification of their pattern and their differential diagnosis. The benefit of MRI is that information images of the basic structures of the small pelvis can be obtained in patients with a marked commissural process after hysterectomy in the absence of limitations in large mass sizes. Practical guidelines were proposed to comprehensively use USS and MRI for the diagnosis of small pelvic pathology.

[Complex radiodiagnosis of oropharyngeal neoplasms].

The paper describes the magnetic resonance imaging (MRI) and spiral computed tomographic (SCT) symptoms of malignant and benign tumors of the oral cavity and throat. It also depicts different types of tumors, such as squamous cell carcinoma, adenocarcinoma, papilloma, and lipoma. The MRI and SCT symptoms of malignant and benign tumors, as well as metastatic lesion in lymph nodes and destruction of bone elements are described in detail.

[Optical density of the mandibular head in cases of TMJ dysfunction and asymmetry of masticatory muscles activity].

There was an examination of 20 patients (12 women and 8 men), aged 30 to 50, with TMJ dysfunction and with partial absence and abrasion of teeth with decrease in the height of the lower facial part and distal mandible shift, and of 12 people (7 women and 5 men), aged 20 to 40, with intact dentitions using electromyography of masticatory muscles and computer tomography, followed by evaluation of the optical density of mandibular head. Analysis of the results enabled to determine the presence of disorders of the balanced activity of masticatory muscles and enables to determine alterations in the optical density of mandibular head. It is necessary to consider the obtained data in planning the prosthetic treatment and preparation of the mouth for prosthetics of patients with TMJ pathology.

[MR imaging in the diagnosis of rheumatoid arthritis]. / Magnitno-rezonansnaia tomografiia v diagnostike revmatoidnogo artrita.

AIM: To study diagnostic potential of MR imaging (MRI) in rheumatoid arthritis (RA). MATERIAL AND METHODS: Clinical-radiation and MRI examinations of the joints were performed in 110 patients. RESULTS: MRI symptoms of RA were determined including accumulation of liquid in the joint cavity, degeneration of the joint cartilage, meniscus, ligaments, proliferation of synovial coating, destructive changes in bone epiphysis. CONCLUSION: Comparative analysis of x-ray and MRI results showed advantages of MRI in detection of inflammatory changes in soft-tissue structures of the joints in RA.

[Magnetic resonance imaging in the diagnosis of tuberculous arthritis]. / Magnitno-rezonansnaia tomografiia v diagnostike tuberkuleznogo artrita.

A complex of clinical radiation and MRI studies of the joint was conducted in 45 patients with tuberculous arthritis. Two major forms of tuberculous lesion of the joint were identified: primary osseous tuberculous arthritis (79.6%) and tuberculous allergic synovitis (20.4%). In patients with tuberculous allergic synovitis, MRI revealed a nonspecific exudative proliferative response of the synovial membrane and edema of the bone marrow and periarticular tissues. In primary osseous tuberculous arthritis, MRI showed tuberculous inflammation foci in the epiphysis of the bone; proliferative changes in the synovial membrane, destruction of cartilaginous, fibrous, and osseous structures, as well as periarticular abscesses.

[Magnetic resonance Imaging in the diagnosis of hemophilic lesions of joints]. / Magnitno-rezonansnaia tomografiia v diagnostike gemofilicheskikh porazhenii sustavov.

A complex clinical, X-ray, and magnetic resonance tomographic study of 327 joints was made in 114 patients with different forms of hemophilic arthropathy. The diagnostic potentialities of MRI were defined and the MRI symptoms of hemophilic arthropathy, including degeneration of the articular cartilage, meniscus, ligaments, proliferation of the synovial membrane, fibrosis, blood accumulation, and hemosiderosis were revealed. Comparative analysis of the X-ray and MRI imaging findings of the joints at different stages of hemophilic arthropathy has shown that MRI has advantages in diagnosing acute and chronic hemarthrosis, moderate hemophilic osteoarthrosis as it can reveal abnormal processes in the X-ray negative structures of joints.

[Diagnosis of rheumatoid arthritis of knee joints using magnetic resonance imaging]. / Diagnostika revmatoidnogo artrita kolennykh sustavov s ispol'zovaniem magnitno-rezonansnoi tomografii.

A combination of clinical, X-Ray and magnetic resonance tomographic studies for 129 knee joints was made in 85 patients with rheumatoid arthritis of knee joints. MRI symptoms of rheumatoid arthritis of knee joints, including fluid accumulation in the articular cavity, degeneration of the articular cartilage, meniscus, ligaments, proliferation of the synovial membrane, destructive changes in osseous epiphysis were defined. Comparative analysis of the X-Ray and MRI imaging findings has shown that MRI has advantages structures of joints in rheumatoid arthritis.

[Study of polymorphism of strains of Vibrio cholerae of various origins using a method of genomic fingerprinting]. / Izuchenie polimorfizma shtammov kholernogo vibriona raznogo proiskhozhdeniia metodom genomnoi daktiloskopii.

Population of atoxigenic Eltor vibrios (vct-) isolated from open water has been shown to be heterogeneous by the genomic fingerprinting technique. Epidemically dangerous strains (vct+) containing the gene coding for cholera toxin have similar hybridization profile independent of time and place of their isolation. The clonal formation of vct+ strains and the absence of vct----vct+ transition of strains under natural conditions are discussed.
