[Neurologic disorders in insulinoma].

Three cases of insulinoma-related neuropsychic disturbances and literature data are considered. Special emphasis is given to polymorphism of epileptiform syndrome, concomitant disphoric paroxyms and lethargy. A case of a rare syndrome coma vigil is described in the advanced stage of the disease. The discussion covers pathogenetic mechanisms and differential diagnosis.

[Value of echography in the differential diagnosis of benign and malignant corticosteromas].

Altogether 34 patients with corticosteroma were examined. In 29 (85%) of them accurate topical diagnosis was established as a result of ultrasonic investigation. All erroneous results were obtained only for corticosteromas of small sizes (4 cm and less in diameter). Tumors not exceeding 4 cm in diameter were benign in 88% of cases. If tumor sizes were over 4 cm, they were malignant in 89%. The earliest possible investigation for the presence or absence of a tumor was indicated to patients with hypercorticism.

Morphological changes in the adrenal cortex in different variants of low-renin hyperaldosteronism. Comparison with the functional state of certain hormonal systems.

On the basis of morphological and histochemical examination of adrenal tissue of 45 patients with arterial hypertension and low-renin hyperaldosteronism, the following five morphological variants of this disease were differentiated: 1) with adenoma of the adrenal cortex and atrophy of surrounding cortical tissue; 2) with adenoma and hyperplasia of elements of the zona glomerulosa and(or) the zona fasciculata and the zona reticularis; 3) with multiple adenomatosis of the adrenal cortex; 4) with isolated diffuse or focal hyperplasia of the zona glomerulosa; 5) with nodal, diffuse-nodal or diffuse hyperplasia of all cortical zones. In tumours, three structural variants, corresponding to their histogenesis, were identified. A correlation was found between morphological variants and hormonal diagnosis of different forms of low-renin hyperaldosteronism.

[Use of echography for diagnosing aldosteromas].

Altogether 23 patients were examined to assess the value of echography in the diagnosis of aldosteromas. Tumors were diagnosed at operation in 21 (2 malignant tumors) and adrenal hyperplasia in 2. The accuracy of diagnosis with regard to the presence or absence of aldosteromas was 82.6%. An analysis of the causes of erroneous results showed that they were noted in small size formations less than 2 cm in diameter, in corpulent patients and in the left-side tumor site due to more complicated anatomotopographic interrelationships of the organs in this area.
