Right hemisphere patients' judgements on emotions.

A triadic comparison technique was used to assess brain-damaged patients' ability to judge the relatedness of a number of emotions, using either a pictorial or verbal material. Emotionally neutral material served as a control. Right hemisphere patients also differed from normals in processing emotions when presented with verbal material. It is suggested that central rather than only peripheral aspects in recognition of emotions are disturbed after injury to the right hemisphere.

Testicular biopsy of azoospermic men with vas deferens malformation using two different techniques.

A morphological analysis was carried out on testicular biopsies of men with obstructive azoospermia as consequence of vas deferens malformations as compared with biopsies from fertile men. For each case the biopsies were processed with two different techniques: routine histological procedure, and semithin sections of specimens processed for electron microscopy. Four parameters were considered: tubular morphology, testicular biopsy score count (TBSC), tubular diameter, and germinal cell density. The data were quantified and analyzed by statistical tests. The biopsies of azoospermic men present a higher frequency of tubular sections with "tubular blockage," "sloughing" and cellular degeneration, lower values of TBSC, and lower germinal cell density. The results appear to be of relevant interest in relation to the existence of long-term testicular alteration following vasectomy.

Gastric stricture following migration of the Angelchik prosthesis. A case report.

An unusual case of migration of an Angelchik esophageal antireflux prosthesis is reported. It was displaced at the middle third of gastric body, in a 49-year old female patient, who had undergone a surgical correction of hiatal hernia 6 months before and it had induced a severe narrowing of gastric lumen. Surgeons using this device should be aware of its various complications and employ it only in particular cases.

The morphology of seminiferous tubules of human testicular biopsies. Analysis of the data obtained with two different techniques.

Testicular biopsies of fertile men and of azoospermic patients for vas deferens agenesis were processed with two different techniques, i.e. routine histological procedure and semithin sections of electron microscopy preparations. Tubular morphology, testicular biopsy score count and tubular diameter were analyzed in comparison. The two techniques give rise to a different qualitative and quantitative evaluation of all tubular parameters considered. Otherwise they confirm the real existence of the so-called 'tubular blockage' situation with central tubular cellular mass and cell degeneration.

Noninvasive detection of insulation break.

The electric current leak through an unsealed connector or insulation break can be a source of problems in cardiac pacing. This study describes a method of leak detection. The underdrive inhibition test--chest wall stimulation with external stimulator (ES)--was used for this purpose. Three cutaneous electrodes (CE) were applied: the first one above the indifferent electrode, the second one above the suspected leak location, and the third one above the active electrode. Two inhibition thresholds (IT) were measured: the first one connecting ES on first CE and second CE, and the second one connecting ES on first CE and third CE. The inhibition threshold is the value of ES output charge at which the inhibition of implanted pacemaker occurs. The relation between two ITs, not the absolute value, is significant for leak estimation. The former should be at least five times higher than the latter, if there is no current leak. During the two years of follow-up of 541 patients, 272 measurements were performed. In 52 cases the connector leak was found-both ITs were approximately equal. Twenty-seven cases were confirmed by surgery for EOL pacemaker replacement; the intrusion of body fluid was evident. Five operations were indicated because of the leak problem: two--muscle twitching, one--loss of capture, one-undersensing, and one--insulation break with lead fracture. The method, although approximate, is a reliable qualitative estimation of leak.

[Retroperitoneal hematoma in children with hemophilia].

The cases of two boys with hemophilia and retroperitoneal haematoma are presented; the diagnosis was confirmed by means of ultrasound scanning. The clinical picture of retroperitoneal haematoma can not be distinguished from other acute abdominal conditions (retroperitoneal infiltrate, or abscess). These pathological processes require surgical treatment, whereas such one in the patients suffering from haemophilia with retroperitoneal haematoma is contraindicated. The diagnosis of retroperitoneal haematoma can be confirmed with a great certainty by means of ultrasound scanning.

[Use of the free venous auto-transplant of the "patch" type in the prevention and treatment of ureteral stenoses. Experimental study with emphasis on the functional value of the operation].

The author analyze the problems of transplantation of the free venous auto-transplant which they implant in the milieu of the urinary system at the location of a previously intentionally performed defect on the side of the ureter. Distinctively, they examine the functional value of such an operation. The experimental model was chosen as the ureter of a dog. A free venous auto-transplant, elliptical in shape (patch) with standard dimensions 2cm-6mm is built in a defect of the ureter side. Fifteen days after the operation an intravenous urography is done, while is repeated after four months. The findings of the urography show consistent values. Four months after the operation in order to check the functional value of the operation a dynamic scintigraphy of the kidneys together with computer data processing is done. An intravenous injection is given to the dogs of 25 micro Curie Hipurin (ortho-iod-hippuric acid labeled with J131). Following this, the dogs are put under a Gamma camera (LFOV - Searle), while registers a accumulation of activity. The results are expressed by a dynamic graph; from which it is easily seen that part of the graph, which relates to the disappearance of activity is almost identical with the graph of the non-operated half of the urinary system. This shows the functional equivalence of the operated and non-operated sides. Such good functional results are obtained in all trials. All together 6 dogs are operated and a total of 8 operations are performed. The results of this work, as well as the clinical experience of other author allow us to propose the application of the free venous auto-transplant (patch), in the cure and prevention of the stenosis of the ureter of the shorter segment at specific indications.

[Percutaneous medial transcondylar osteosynthesis in supracondylar fractures of the humerus].

The authors describe their own method of fragments using Kirshner Wire in supracondylar extension fractures of the humerus. Of a total of 118 extension fractures 74 were of a III degree dislocation type. In 16 of these, the medial percutaneous fixation method was implemented. Indications for surgical intervention included those cases in which good positioning of the fragments could not be maintained due to edema, in cases in which flexion at the elbow caused a loss of the radial pulse, and in cases of manifested primary injury of the ulnar nerve. Following the repositioning of the fragments, 2--3 Kirshner wires were placed immediately above the olecranon along the medial line and through the lower and upper fragments. These wires were left in place for 14 days during which time the arm was kept immobilized. Rehabilitation was begun immediately following the removal of the wires. The end results were excellent and no early or late complications occurred.
