[Lymphography and fine needle puncture biopsy in the evaluation of lymph node involvement. Apropos of 207 cases].

Percutaneous fine needle puncture biopsy was performed on lymph nodes taking up contrast during lymphography in 207 patients with various disorders: urogenital (174 cases), gynecologic (13 cases), hematologic (17), others (3). At the present time, in fact, and simultaneously with the development of physical methods of diagnostic exploration (ultrasonography, computed tomography) needle puncture biopsy has become of increasing importance to confirm a suspected diagnosis. Needle puncture biopsy under television control is a simple, painless and practically nontraumatic procedure. When performed under precise conditions and a strict methodology (routine sampling as a function of the primary glandular chains), it establishes the correct diagnosis in a large number of lymphographies, enabling a rapid and more precise evaluation of the degree of extension and thus a better therapeutic choice.

[Experimental evidence for motoric rehabilitation in lymphoedema (author's transl)].

The authors distinguish three modalities of lymphtransport in lymphoedema. 1. Enhanced evacuation by existing lymphatics. 2. Enhanced evacuation by regenerated lymphatics. 3. Enhanced evacuation by lympho-lymphatic anastomoses. Experiments with 500 white mice indicate that the resorption of lymphoedema is increased by guided compression, although some manipulations must be performed with care, especially when regenerated lymphatics are present. The lymphatic flow in a limb is also enhanced by a special drainage technique at the proximal part of it. Likewise the lymph can be manipulated into the opposite limb by anastomotic channels after unilateral lymphadenectomy.

Assessment of skin temperature elevation and heat diffusion with electrosurgical currents.

A model was developed to quantitatively predict skin and tissue temperature elevations as a function of the amplitude and duration of the electrosurgical current applied, the geometry of the electrodes used, and the skin and tissue properties of the subjects. The temperature measurements were performed with thermographic equipment. The experimental data fit the model, thus fewer measurements will now be required for studies of other electrode designs.
