CD antigens 2001.

The most recent Human Leucocyte Differentiation Antigen Workshop ("HLDA7") took place in 2000 in Harrogate, UK and the proceedings are about to be published (Leucocyte Typing VII). New Sections were introduced in this Workship (Dendritic cells, Stem/progenitor cells, Erythroid cells and Carbohydrate Structures) and monoclonal antibodies were selected for which at least some molecular data were already available (to avoid "blind" screening of reagents against known specificities). A total of more than 80 new CD specificities were established (previously the average was less than 30 new CD specificities per Workshop) and these are listed in this article. There is already evidence for the existence of many new leucocyte surface molecules for study at the next HLDA Workshop (in Adelaide in 2004), and we have listed in this article a number of such potential CD candidates (identified following the production of monoclonal antibodies or via gene cloning). There are also today an increasing number of lineage- and/or stage-restricted leucocyte-associated molecules localised within the cell cytoplasm (or nucleus): they will certainly prove of intense in the future for many laboratories studying human haematopoietic cells (regardless of whether a new "intracellular CD" categorisation scheme is devised for such molecules).

Occult thyrotoxicosis in patients with atrial fibrillation and an acute arterial embolism.

Serum total thyroxine, triiodothyronine, and thyrotropin response to thyrotropin-releasing hormone (TRH-TSH test) were measured in 126 consecutive patients admitted with atrial fibrillation: 33 patients with an acute arterial limb embolism (Group I), 31 patients with an acute embolic stroke (Group II), and 62 patients without any arterial occlusion (Group III). A blunted TRH-TSH test, suggestive of thyrotoxicosis, was found in 5 patients in Group I, 8 patients in Group II, and 2 patients in Group III. The diagnosis of hyperthyroidism was confirmed in 8 patients (by repeated TRH-TSH test and scintigraphy): 4 patients in Group I (12.1%) and 4 patients in Group II (12.9%). All of them had a nonvalvular atrial fibrillation. Thyrotoxicosis should not be recognized in 6 of them if TRH-TSH test was not performed, because peripheral hormone levels were normal. Five of these 8 patients with thyrotoxicosis had reversion to sinus rhythm after treatment with carbimazole, either spontaneously or after cardioversion. This outcome prevented prolongation of anticoagulant therapy for an indefinite time.

[Aortobifemoral prostheses with "0" porosity. Results after 2 years' experience].

During the last years diverse types of Dacron prosthesis without porosity (because to be impregnated by different materials) have appeared. In the presented study, outcomes from three different types of prosthesis (differentiated by the impregnated material) were evaluated and a comparison with classical prosthesis was made.

[Capillaroscopic observation in angiologic diagnosis].

The authors present their experience with Morphologic Capillaroscopy, and analyze the diagnostic dates provided by this technique to the current Angiology and Vascular Surgery protocols. Morphologic anomalies founded during diverse systemic diseases as well as the changes on the capillary field produced in cases of chronic ischaemia and venous insufficiency were analysed. The study was made on the basis of 236 capillaroscopic images and it was completed by an extensive bibliographic review of the subject.

[Effect of peripheral parenteral nutrition on the immediate postoperative period in surgery of the aortic sector].

There is not an extensive literature about nutritional value in Vascular Surgery. In this study, efficacy and cost/benefit relation in the application of Peripheric Parenteral Nutrition (PPN) in postoperative of aortic surgery, are investigated through two randomized groups, in patients with aortoiliac obstructive arteriopathy and who needed an aortobifemoral bypass.

Hydatid cyst fistula into the aorta.

A case is presented of fistula formation between a primary hydatid cyst and the abdominal aorta which we believe is the first in the world literature. The patient underwent surgery with a diagnosis of aneurysm of the coeliac trunk. During the operation the presence was discovered of a hydatid cyst opening into the aorta. It was dealt with by partial resection and closing of the communication. Three months later the patient was readmitted with a new bleeding episode which resulted in a fatal outcome.
