Correlations of somatophysiological, biochemical, psychosocial and behavioral risk factors of cardiovascular diseases in a sample of employees of Prague enterprises and institutions.

The study is aimed at the detection and intervention of risk factors for cardiovascular diseases (CVD) and at the part played by stress in their development. The methods applied are designed to eliminate the risks and, simultaneously, to identify the function of the two main parts of stress reaction, i.e., in terms of the extent, level and type of the stressors experienced, and in terms of the level of mental resilience and related psychosocial factors which affect the experiencing of and coping with stress. The purpose of medical examination based on the patient's history, subjective complaints and objective tests, including a study of dietary habits and psychological methods was to establish the status praesens and identify the main risk factors and symptoms leading to ischemic heart disease (IHD). Intervention was performed in subjects with increased cardiovalscular risk factors.

A revised coil for the external cooling of the kidney.

The authors describe a coil they have developed for contact peroperative hypothermia of the kidney. This new type of coil eliminates the disadvantages of existing cooling coils, namely slow thermal transfer from kidney to cooling agent due to imperfect contact between the coil and the concave surface of the kidney, use of an inadequately conductive material and thermal losses from the outer surface of the coil. Special features of the coil described here include its construction to match the contours of the kidney, isolation of external shell to reduce thermal losses and continuous monitoring of renal tissue to reduce the danger of overcooling.

[Ultrasonography in the diagnosis of hyperparathyroidism].

Ultrasonography is a direct method of representation, giving various advantages over other methods in the examination of parathyroid glands: it is rapid, non-radiation and economically undemanding. Dynamic examination by means of the linear electronic transducer of 3.5 MHz and the use of water path was used in 37 patients. In 7 patients with primary hyperparathyroidism was the examination rapid and the pictures of the adenomas were persuasive. In 30 patients with secondary hyperparathyroidism were found characteristic pictures, if the glands were enlarged to 8 mm or more. For the diagnosis of smaller glands a high resolution transducer will be necessary. Histological finding was available in 21 patients undergoing operation, and easily available method and it is therefore the procedure of the first choice.

[Computer tomography in the diagnosis of hyperparathyroidism].

The paper presents long-term experience in the diagnosis of hyperparathyroidism by means of computer tomography. A large number of examinations (164) of parathyroid glands, the possibility of verification and comparison with sonography or with other diagnostic methods of visualization make it possible to define the role of computer tomography in hyperparathyroidism and to show advantages and limitations of the method. For the high diagnostic precision the CT examination may be considered to be the reliable method in the demonstration of enlarged parathyroid glands.

[Reconstructive procedures in war injuries of the larynx and trachea].

In recent years the authors operated three casualties from non-European battlefields with severe laryngotracheal stenoses due to war injuries. Median laryngotomy (thyrocricotracheotomy) made a revision and modification of the internal injury possible. An implanted tube from a vascular prosthesis, packed in Hydron kept the replaced cartilaginous cross bar and possibly mucous grafts from a gingivobuccal fold in the correct position. A cross bar made from a cartilaginous or bony portion of a rib also dilated the lumen. It was kept in position by the perichondrium of the cartilaginous cross bar sutured to the margin of the mucosal remnants. All three patients were decannulated.

Somatosensory evoked potentials in patients with occlusions of cerebral arteries.

The material consists of 100 patients suffering from occlusion of a cerebral artery, admitted for the performance of arterial bypass. Before the operation SEPs of the median nerve and CT scans were taken. Three main types of SEP were found (symmetric, asymmetric-attenuated, asymmetric-augmented) and pathological changes of latency, amplitude and wave form of the primary complex N1-P2 were described. The changes were correlated with the localization and extent of the hypodense lesion in the cerebral hemispheres. The cause of the decreased latencies on the side of the lesion is discussed and reported in relation to 'travelling waves' (Cracco 1980) in normals. The cause of the increased amplitude on the side of the lesion is also discussed and reported in relation to a disturbance of the suppressor cortex 8s, 19s and of the head of the caudate nucleus.
