La contribution de Jacques Lacan au débat sur la psychose infantile en 1953

There is a teaching by J. Lacan on childhood psychosis which begins from its first seminary in 1953. J. Lacan comments at first on Dick's case, which is presented by M. Klein in 1930, then Robert's case, presented in its seminary by one of his learners, Rosine Lefort. Assuming the comment of Freud's text “Die Verneinung” by J. Hyppolite, and its consequences about difference between symbolisation in general and Bejahung in particular, J. Lacan show what will becoming the very structure of psychosis, that is to say the gap of a fundamental significant, which is, here, the “idéal du moi”.     

Endocardial mapping by simultaneous recording of endocardial electrograms during cardiac surgery for ventricular aneurysm

A technique was developed for the simultaneous recording of 30 endocardial electrograms during cardiac surgery in patients undergoing aneurysmectomy or endocardial resection, or both, for medically intractable ventricular tachycardia. An inflatable balloon covered with 30 terminals at distances of 1.5 to 2 cm was used to record from the entire endocardial surface; a smaller silicone rubber sheet with 30 terminals at distances of 0.7 cm was used to obtain a better spatial resolution. The multielectrodes were inserted into the left ventricular cavity by way of an incision in the aneurysm. A transportable minicomputer was used for the acquisition and analysis of the signals. After initiation of ventricular tachycardia by programmed stimulation, signals of a 1.5 second period were stored and analyzed. The earliest activated terminal could be determined within 2 to 5 minutes. The technique was applied in 32 patients and proved especially useful in those patients in whom sustained tachycardia could not be evoked and in whom conventional mapping with a roving electrode would have been impossible or very time consuming. In all patients, the isochronic maps showed that the ectopic impulses originated from a rather localized area and no evidence was found for large endocardial circus movements, thereby excluding these as a mechanism underlying the tachycardia. Isochronic maps, depicting activation sequences during consecutive ectopic beats with the same QRS morphologic features, showed the same site of origin in all but six patients.(ABSTRACT TRUNCATED AT 250 WORDS)     

Translocation 1;7 in hematologic disorders: a brief review of 22 cases

A translocation t(1;7)(p11;p11), previously reported in patients with myelodysplasia or leukemia has been found in seven new cases. The present report briefly reviews the cytogenetic and clinical features of 22 patients with this translocation. The majority of these patients had a history of occupational or therapeutic exposure to toxic substances or radiation. Trisomy 8 or 21 were the most common additional abnormalities, especially in leukemic patients. The t(1;7) should be added to the group of specific cytogenetic abnormalities observed frequently in secondary myelodysplasia and leukemia.
