[Ultrasound, computer tomography and angiography in the diagnosis of dissecting aortic aneurysm].

The findings obtained by ultrasound, CT and angiographic examinations of 75 patients with dissecting aortic aneurysms operated on at the M.M.A. are analysed. The aim of each particular method was to detect the presence of dissection, the aortic entrance tear and type of dissection. These findings were compared with the operative findings. On the basis of the analysis it has been concluded that the precision of the diagnosis obtained by angiography was 93%, by CT 74% and by ultrasound 69%.

[Hemodialysis in children and beta 2-microglobulin].

Retention of beta-2-microglobulin, due to loss of excretory renal function inevitably occurs in uremia. A significant correlation between the duration of hemodialysis and the incidence of carpal tunnel syndrome or destructive cystic lesions of bone has been reported. Amyloid deposition has been found to directly cause these lesions. This amyloid protein has been identified to be beta-2-microglobulin. The aim of this report was to study plasma beta-2-microglobulin levels in hemodialysed children and to detect clinical manifestations or carpal tunnel syndrome and of bone lesions. 12 children aged 9-24 years were studied. The average duration of dialysis was 51.9 ae 32 months. Beta-2-microglobulin plasma levels were studied before and after hemodialysis treatment. All patients were examined for carpal tunnel syndrome using clinical methods including nerve conduction studies, and for destructive cystic lesions using X-rays of bone. Plasma beta-2-microglobulin concentrations in our patients were found to be sevrefold time higher (73.8 ae 22.1 mg/l) than control values (1.6 ae 0.5 mg/l). The increase of beta-2-microglobulin concentration during hemodialysis tratment was due probably by hemoconcentration. We noted poor correlation between plasma beta-2-microglobulin and duration of hemodialysis. Any signs of carpal tunnel syndrome was found to our patients. Radiological signs of amyloid osteopathy found to be present in 3 children, was not verified by bone biopsy.

[The importance of physical therapy in the treatment of Volkmann's contracture in children].

Over the period from 1981 to 1991 twenty-eight children were treated for neurovascular posttraumatic complications (Volkman's contracture), in the Centre for rehabilitation and physical medicine of the Children's surgical department in Belgrade. The success of the treatment depended on how a patient was examined for the first time, and how soon a proper diagnosis was established. On the basis of our experience we insist on an early physical treatment, i.e. while the injured segment is immobilized. An early kinesitherapy followed later by electrotherapy, parafino-therapy, vitamin B therapy and use of corrective plaster cast splints is the best way in treating lesions. The treatment lasted from 3 to 6 months depending on the seriousness of an injury. If there was no good result with physical therapy we carried out surgery followed by physical therapy upon the removal of immobilisation devices.

[The value of echotomographic measurement of gallbladder volume in the evaluation of its contractility].

Ultrasonographic examination of the gallbladder was performed in 2 patient groups: 20 volunteers (group I) and 20 patients with cholelithiasis (group II). Gallbladder volume was echotomographically measured before and after holagogue was administered. Dodd's ellipsoidal method was used for the elevation of gallbladder contractility. The mean value of gallbladder contractility was 69.9% in the group of volunteers. After the holagogue administration, the decrease of gallbladder volume was noticed in all the studied patients. In group of patients with cholelithiasis, the reaction after holagogue administration was different: the increase of gallbladder volume was noticed in 8 patients after the holagogue administration and the poor gallbladder contractility (below 50%) was noticed in 8 patients. Four patients had no reaction after the holagogue administration. Echotomography was determined to be reliable method in the diagnosis of gallbladder contractility disturbances.

[Hemodynamic significance of fluoroscopic diagnosis of coronary artery calcification].

The onset of coronary arterial calcification is an active, organized, metabolically regulated process that occurs only when the initial changes of atherosclerosis are present. Coronary arterial calcification may represent an attempt to protect the arterial wall mechanically. Determination of hemodynamic significance in detecting coronary heart disease was the aim of the study. 110 patients with suspected angina pectoris were performed fluoroscopy and coronary angiography after-wards. In 77 patients (70%) was determined coronary arteriosclerosis using coronary angiography, and in 33 (30%), finding was normal. Out of 77 (70%) patients with positive funding in 44 patients (57.14%) calcifications were detect using fluoroscopy, while in 33 (42.86%) were not. Out of 33 (30%) patients without arteriosclerosis calcifications were detected in 5 (15.15%) patients, and in 28 (84.85%) were not. According to our results and literature review, the calcification finding confirms the presence of already existing significant stenosis on the coronary artery or a high risk for hemodynamic disorder within the next two to five years.
