[Skeletal scintigraphy in hemangioma of the bones].

The results of scintigraphic investigations of the skeleton of 76 bone hemangioma patients were analyzed to study the informative value of this type of investigation and to determine the efficacy of its use during establishing diagnosis and dynamic observation. The probability of detection of bone hemangiomas using scintigraphy of the skeleton with 99m Tc labeled osteotropic agents was shown to be in direct relation to the biological activity of hemangioma, its site and resolution of radiodiagnostic apparatus. The utilization of scintigraphy of the skeleton in addition to x-ray investigation permits clarification of the nature of lesion (benign or malignant), the biological activity of hemangiomas, control of the time course of a pathological process and efficacy of therapy of biologically active hemangiomas.

[X-ray features of fibrous osteodystrophy and osteomalacia in patients with chronic renal insufficiency under present-day treatment].

The authors present the results of clinicoroentgenological and biochemical investigations in 102 patients with chronic renal insufficiency after hemodialysis and in 76 patients after kidney transplantation. The nature of secondary hyperparathyroid fibrous osteodystrophy and osteomalacia as main symptoms of nephrogenic osteodystrophy (NO), their interrelation and correlation are analysed. Of 178 patients pathological changes of the bone system were revealed in 94 (52.9%). The combination of fibrous osteodystrophy and osteomalacia (22%) is regarded as a contraindication for parathyroidectomy. Effective kidney transplantation does not prevent NO though its specificity changes: osteomalacia is more marked, osteonecrosis and soft tissue calcification are more common. The chief method of radiodiagnosis of NO is routine radiography of the skeleton supplemented by small feature contact radiography and x-ray image color analysis on the UAR and TELEVAN TV units. Comparative roentgenodensitometry of the bones and CT of the parathyroid glands contributed to obtaining objective information but was of applied value.

[Bone tissue in patients with hyperprolactinemic hypogonadism].

Sixteen women with hyperprolactinemia were examined for Ca metabolism, osseous metabolism, mineral saturation of bone tissue in the thoracic portion of the spine and radius. Lowered mineral saturation of the thoracic vertebrae was detected in 69% of the examinees, that of the distal segment of the radius in 44%. Reduction of the mineral saturation of the spine was in negative correlation with the blood prolactin level and length of amenorrhea. No changes in the bone resorption biochemistry or Ca metabolism were detected. A marked reduction of blood osteocalcin level that reflects osteoblast function was detected, its blood concentration being in negative correlation with prolactin level. No relationships between mineral saturation of bone tissue, prolactin, and osteocalcin, on the one hand, and blood estradiol level, on the other, were observed. These data suggest that osteopathy in hyperprolactinemic hypogonadism is due to reduced bone formation and not to reduced estradiol production.

[Comparison of diagnostic methods for osteoporosis in endogenous hypercorticism].

The informative value of diagnosis of osteoporosis in 53 patients with Itsenko-Cushing disease was assessed by visual estimation of radiograms of the axial skeleton, standard x-ray densitometry of the phalanges of the thumbs and single-photon absorptiometry of the distal parts of antebrachial bones. Diagnosis of osteoporosis and its evaluation over time were shown to be accurate in combination of visual assessment of radiograms of the axial skeleton with standard x-ray densitometry of the peripheral parts of the skeleton. Single-photon absorptiometry revealed no decrease in the level of the osseous mineral in the forearm of patients with endogenous hypercorticoidism. In the majority of female patients this indicator even exceeded the normal age value. Possible causes of this phenomenon are under discussion.
