Intra-atrial and atrioventricular nodal reentrant tachycardia in the same subject diagnosed at transesophageal electrophysiologic study.

The case report deals with a young woman with frequent episodes of paroxysmal narrow QRS tachycardia of uncertain etiology at Holter monitoring in whom a transesophageal electrophysiologic study was carried out in order to identify the electrogenetic mechanism of the presenting arrhythmia. During the electrophysiologic study, 2 different types of supraventricular tachycardia were induced and diagnosed as intra-atrial and atrioventricular nodal reentrant tachycardia. This association represents a rare finding and can provide a possible explanation to the intriguing electrocardiographic pattern observed at Holter monitoring. Therefore, transesophageal electrophysiologic study proved to be a valuable method for evaluating subjects with complex supraventricular tachycardias.

Monoclonal antibody investigation in rheumatoid arthritis: presence of a T cell subpopulation bearing a double marker.

Using a double marking technique of peripheral blood lymphocyte (PBL) from 23 patients suffering from rheumatoid arthritis (RA) and 12 normal healthy subjects (NHS), the authors were able to demonstrate that there was no alteration in the OKT8 + ve population of RA patients, when compared with NHS. On the contrary, an increased percentage of the subpopulation of lymphocytes OKT4 + ve was detected. Finally, the presence of a subpopulation of T cells carrying both the receptors for monoclonal antibodies OKT4 and OKT8 has been detected.
