[The morphofunctional characteristics of the duodenum in an osteopenic syndrome in children and adolescents].

AIM: The study of duodenal morphology in children and adolescents with skeletal deformity. MATERIALS AND METHODS: Clinical, hormonal examinations, x-ray investigation of the skeleton with spinal NMR-tomography, gastroduodenoscopy with target biopsy were performed in 41 patients aged 7 to 18 on after treatment for broken spine. RESULTS: Atrophic duodenitis found in most of the patients presented without dyspepsia, with symptoms of duodenitis in 8 patients, osteoporosis in 36% of patients. NMR-tomography rejected compression-broken spine in 22 patients. CONCLUSION: Disturbed absorption of calcium and atrophic alterations in the duodenal mucosa are thought responsible for disturbance of calcium metabolism and formation of bone tissue.

[Osteopathy in malabsorption syndromes].

Electrolytic imbalance is a frequent finding in malabsorption syndrome. Derangement of calcium metabolism present clinically in different variants is most serious. Some patients develop hypocalcemia manifesting clinically with specific myasthenia, paresthesias, convulsions, hemorrhages, etc. In other variants severe skeletal lesions are seen which may become dominating in the clinical picture though hypocalcemia was absent. Investigation of calcium metabolism, hormonal profile (parathormone, in particular) in malabsorption syndrome can prognosticate and prevent the onset of osteomalacia.

[Diagnostic value of the system of Frank's orthogonal leads in inveterate myocardial infarct].

Comparison of data obtained in recording corrected orthogonal leads of the Frank system and 12 classical ECG leads in 118 patients with ischemic heart disease, among whom there were 76 patients with an old myocardial infarction, showed that corrected orthogonal leads may be used in mass population survey with the use of automatic diagnostic machines. It was established that the following ECG indices may be used in recording Frank's corrected orthogonal leads in the diagnosis of cicatricial myocardial changes: amplitude and duration of Q wave, the Q/R and R/S coefficients, the appearance of wave S in lead "Z". In an old myocardial infarction of posterior localization changes are recorded in lead "Y", in infarction of antero-septal localization changes are recorded in lead "Z" and to a lesser degree in lead "X"; in infarction of antero-lateral localization changes are recorded in lead "X" and to a lesser degree in lead "Z".

[Radiation diagnosis of involutional osteopenia].

160 patients with involutive osteopaenia were investigated. The diagnostic possibilities of roentgenography, magnetic resonance imaging and computed tomography were evaluated. There was determined that roentgenography gives the possibility to determine the common localisation and the expressiveness of the pathologic process. MRI and CT give a valuable additional information on early stages of osteopaenia and it's complications.
