[Lung cancer in survivors of radiation exposure at the Chernobyl nuclear disaster].

Epidemiology, diagnostics and therapy of lung cancer in the aftermath of Chernobyl nuclear disaster are discussed on the basis of the data released by the Federal Expert Committee. Lung cancer appeared to be the main death-causing factor. The disease was far advanced (stage IIIb and IV) in 85% of cases. The effectiveness of diagnosis can be raised if such compulsory measures as annual bronchoscopic screenings and sputum counts are carried out. Atypical cell counts have to be run in the sputum samples from all the survivors who took part in the salvaging operations of 1986-1987 and are suffering acute and chronic respiratory diseases. Particular attention should be paid to those who were working under severe dust-pollution conditions in summer.

[Value of bone densitometry in the determination of vertebral mineral density in participants of the clean-up after Chernobyl accident].

Scanning osteodensitometry helped to study mineral saturation of lumbar vertebra in individuals who liquidated Chernobyl accident consequences. Bone mineral density appeared to depend on radiation dose obtained by the examinees. High risk of osteoporosis revealed in the examinees who participated in the liquidation in 1986. The authors stress that the examinees should be covered by the skeletal state monitoring possible only with osteodensitometry. The article justify that biphotonic scanning osteodensitometers are expedient in Health Care Centers for individuals who liquidated Chernobyl accident consequences.

[Value of prophylactic investigation of thoracic organs in victims of the Chernobyl power plant disaster].

Relatively low morbidity of tuberculosis of the lung (2 per 1,500) and comparatively high morbidity of ling cancer were reported in 1995-1997 among the liquidators of Chernobyl nuclear power station disaster. Risk of malignant disease involved in X-ray check-ups of the chest has been identified. Low diagnostic value of photoroentgenography for lung tumors has been reported.

[The late sequelae of radiation exposure on the nervous system].

Clinical, neuropsychologic, neurophysiologic as well as neuromorphologic (in legal cases) examinations of Chernobyl liquidators were performed. In addition, the study was made of the monkeys exposed to 1,5 Gy radiation. The results obtained testified to the organic character of cerebral damages. They may be characterised as chronic progressive discirculatory-hypoxic syndrome in which disorders of vascular permeability were expressed and dystrophic destructive irreversible alterations of nervous cells occurred.

[The ultrasonic diagnosis of changes in the hepatobiliary system in the practice of mass medical examinations].

Investigation of 1258 servicemen during the first year of their service using ultrasound scanning of the hepatobiliary system has shown signs of chronic cholecystitis in 170, chronic hepatitis in 70, pyelonephritis and renal calculi in 120; 25 servicemen were recommended for further medical examination. It has been concluded that ultrasound scanning must become part of obligatory investigations of conscripts.

[Ultrasonic scanning of the thyroid in the children of Bryansk Province in 1989].

Ultrasound scanning has shown that the rate of pathological thyroid changes in schoolchildren of the endemic zone is a 2.5-fold high as that in Moscow schoolchildren. Children affected at the Chernobyl accident demonstrated a significant increase in the thyroid size, the frequency of hypoplasia and thypoiditides as compared to indices in children from the endemic area without radioactive contamination.

[A study of the evacuatory function of the small and large intestines using the dynamic scintigraphic method in inflammatory diseases of the intestines].

Intestinal and colon evacuatory function was studied in 10 patients without pathology of the digestive organs and in 66 patients with chronic colitis. This method allows adequate assessment of the state of the hepatobiliary system, intestinal and colon evacuatory function without additional radiation exposure of the examinees and personnel.

[The use of radiodiagnostic apparatus as human radiation counters in large-scale radiation accidents].

The problem of dosimetry of internal irradiation necessitates the use of human radiation counters (HRC). A state system of radiation safety should be based on a HRC stock in case of large-scale radiation accidents. Radiodiagnostic units can run in the HRC mode therefore they must be considered as an active reserve widely spread throughout the country. Radiodiagnostic devices can be used for control of the thyroid level of 131I and the whole-body content of a mixture of 134Cs and 137Cs.

[Ultrasonic scanning in the diagnosis of hepatic alveococcosis].

The echotomographic picture of liver alveococcosis was described on the basis of investigation of 132 patients (the diagnosis in 22 was verified by biopsy). Some features of alterations were determined over time. Radionuclide scanning was shown to be less effective in the diagnosis of liver alveococcosis than echotomography.

[An ultrasonic study in the differential diagnosis of thyroid diseases].

The correlation of clinical, echo and morphological findings demonstrated ultrasound potentialities in the differential diagnosis of thyroid cancer. Ultrasound permitted the detection of nodes up to 3 cm in diameter. False-negative results were obtained in 6.5% of cases, there were no true false positive results. Adenomas are often characterized by mixed echogenicity of a node and hypoechogenic lining around it. Chronic nonspecific thyroid diseases are characterized by inhomogeneous echogenicity of the organ. Thyroid cancer is characterized by hypoechogenicity of a node with its inhomogeneous structure and irregular contours as if consisting of several nodules. The probability of malignancy grows with an increase in the number of these features combining in a particular patient.

[Renoscintigraphy in the differential diagnosis of arterial hypertension].

Altogether 244 persons were examined. Of them 221 patients suffered from the syndrome of arterial hypertension, 23 were controls. Standard renoscintigraphy with 131I-hippuran was performed in all the patients. Routine indices: Tmax, T1/2 and T delta (RP retention mean time) were used as criteria for the assessment of renograms. The diagnostic accuracy of disorders of renal excretory function in patients with arterial hypertension by the results of assessment of renograms using routine indices was 65% only. The introduction of a new index T delta made it possible to raise the accuracy of examination by 35% as a result of the diagnosis of disorders of central hemodynamics.
