    Notes: Abstract A biophysical heart-body model consisting of a liquid bulk conductor, filling a hollow transparent vessel shaped like a human torso, and with an isolated perfused dog's heart immersed in it, is described. Metal electrodes for the various ECG leads are distributed on the inner surface of the vessel. The bulk condcctor consists of NaCl solution. The amplitude of the derived signals was shown to depend on the NaCl concentration. With NaCl in a concentration of 0.004% the amplitude of the ECG obtained on the model was similar to that of the human ECG in the same leads. With an increase in the concentration of the solution the amplitude of the ECG falls rapidly, and with a 0.9% NaCl concentration it becomes almost indistinguishable. To protect the heart from injury by the hypotonic solution, an artificial pericardium made of electrically conducting rubber film is used. The method of placing the heart in the model of the torso also is described. It is suggested that the heart-body model can be used to study problems connected with the experimental investigation of ECG changes in different leads associated with intentionally induced injuries to or changes in the state of the heart.

    Notes: Summary Melorheostosis is a rare, benign disease, usually affecting bones of the extremities by a characteristic hyperostosis causing typical findings on X-ray examination. We report an 18-year-old male with melorheostosis of the right hand. A review of the literature is given.

    Notes: Abstract Occasionally carcinomas of the proximal third of the esophagus invade the trachea. In these cases potential cure or adequate palliation can only be achieved by extensive resection of the hypopharynx, the proximal esophagus and the trachea. Sometimes the sternal manubrium has to be removed to obtain adequate margins of resection. Under these circumstances reconstruction of the digestive tract and creation of a properly functioning tracheal stoma can be challenging. A procedure is described in which a mediastinal tracheal stoma is created by centering the terminal portion of the trachea in a pectoralis myocutaneous flap after resection of the sternal manubrium. Digestive tract reconstruction is achieved by free jejunal transfer. For high thoracic carcinomas the manubrectomy allows resection via a proximal route and facilitates reconstruction. Similarly the integrity of the distal esophagus and stomach can be maintained. The technique is illustrated in two patient reports.

    Notes: Abstract A method of investigating the electric field of the isolated perfused animal's heart in a liquid volume conductor is described. Potentials are recorded from 241 points on a spherical surface surounding the heart by a unipolar technique. The electrodes are 1–2 cm away from the surface of the heart. The leads are grouped together 6 at a time. One of them is recorded as a constituent of all groups and serves for synchronization. The method is intended for the study of various types of equivalent electrical generators of the heart.
