La hipertensión arterial es una identidad que de acuerdo con las estadísticas afecta al 15 por ciento de la población; dentro de las causas de esta enfermedad la hipertensión renovascular sería la responsable del 0,2 al 1 por ciento de los pacientes hipertensos; la hipertensión endócrina tiene similar frecuencia. No todos los pacientes hipertensos son pasibles de ser estudiados para descartar hipertensión secundaria. En el caso que presentamos a continuación nos referimos a un paciente en donde se unen la hipertensión renovascular y la hipertensión endócrina como factores productores de esta afección

The authors report a case of "harlequin fetus" which was brought to their attention. The report was justified not only by the rarity of the disease, but above all because, after having examined the literature on the topic, this appears to be the third case treated with etretinate. The case in question was a female affected by congenital ichthyosis in its total form and by initial necrosis of the extremities. Etretinate treatment gave good results in terms of cutaneous modifications: reduction of hyperkeratosis, disappearance of ectropion and eclabium. Therefore, although the patient died when 16 days old due to sudden renal insufficiency, the case confirms the two previous reports on the value of this therapy.

En el presente trabajo se estudia en forma prospectiva el uso de sonda nasogástrica profiláctica en cirugía abdominal. En la comparación entre 100 pacientes en los que se usó dicho procedimiento y 100 en los que no se usó, se observó en este segundo grupo una disminución de los días de internación y de la necesidad de reposición hidroelectrolítica, como así también una considerable mejoría en el bienestar postoperatorio. La falta de la aspiración gástrica rutinaria no ocasionó inconvenientes, aun en operaciones que incluían anastomosis intestinales. Se concluye que el procedimiento puede ser eliminado sin inconvenientes (AU)

Serum vitamin E values are depressed in thalassaemia owing to increased consumption because of the oxidative stress imposed both to red cells and other tissues by haemochromatosis. A study of vitamin E deficiency was carried over a period of about 2 years in 161 transfusion dependent thalassaemic patients aged 4 months to 18 years (including 74 splenectomized subjects) all following the same transfusion and chelation protocol (pretransfusion Hb = 11 gr/dl and daily chelation with subcutaneous infusion of desferrioxamine 12 hr a day). Serum vitamin E levels were determined by Martinek's method. The mean value for the entire series was 0.45 +/- 0.21 mg/dl (normal value 0.76 +/- 0.22), with no differences between splenectomized (0.43 +/- 0.19) and not--splenectomized (0.45 +/- 0.21) subjects. Values of less than 0.32 mg/dl (mean-2SD) were found in 50 patients (31,1%). Below--normal values were noted in 5/11 patients at the time of diagnosis. 124 subjects with less than 0.54 mg/dl received 5-10 mg/Kg/day vitamin E per os. In 38 cases it has been possible to control vitamin E level after one year of therapy. Mean values before treatment were 0.36 +/- 0.13 mg/dl and 1.19 +/- 0.35 mg/dl after therapy. No patient failed to respond and no adverse effect was recorded. These results show that by no means all thalassaemic patients are vitamin E deficient to the point where replacement therapy is necessary, and oral administration can easily correct low serum levels, contrary to what has been found by other workers.

Increasing the concentration of calcium in the external buffer flowing past isolated, intact bovine retinal rod outer segment disks immobilized in a flow system reduced the rate of radioactive calcium efflux from within the disks in the dark. We interpret these results as extradiskal calcium acting at an inhibitory binding site to block the calcium efflux. A Scatchard analysis of the external calcium dependence of the efflux yields an apparent dissociation constant of 50 microM, which further suggests that the inhibition is mediated by a specific membrane binding site. The observed inhibition of calcium efflux may represent a functional role for the high-affinity calcium binding site which has been identified by others in previous physical studies of the disk membrane. This external calcium inhibited permeability may explain some of the discrepancies in the reported calcium transport properties of disks. Variations in the external calcium concentration may alter the calcium content of isolated disks, thereby indirectly affecting other transport functions including the measured light-induced release of calcium. No evidence was found for either Na/Ca or Ca/Ca exchange processes across the disk membrane. Lanthanum was even more effective than calcium in inhibiting calcium efflux in the dark. Neither lanthanum nor calcium inhibited the light-induced efflux of calcium from disks, which implies either that light and extradiskal calcium regulate separate permeability processes in the disk membrane or that light greatly reduces the affinity of the inhibitory site for calcium and lanthanum.

Alloimmunization of cattle revealed a polymorphism carried on a serum antigen displayed beta-electrophoretic mobility. A genetic test indicated that the antigen is inherited in a Mendelian manner, as product of a dominant allele at an autosomal locus. By immunochemical investigation the allotypic determinant was found to be located on IgA: there were in fact no differences between the peptidic map of the molecule carrying the allotypic determinant and that of IgA from positive sera. Moreover the peptidic map of IgA from sera lacking of the allotype resulted lacking of an anodic peptide, thus suggesting that the polymorphism is indeed due to such a peptide.

Humoral proteins from Amphioxus lanceolatus showed a considerable agglutinating activity for human red cells. The haemagglutinating factor eluted in the macroglobulin peak on Sephadex G200 and resulted ConA-1 at affinity chromatography on Sepharose ConA. Immunoelectrophoresis, carried out using a specific antiserum produced in rabbit, revealed alpha mobility for the agglutinating factor, thus suggesting that it was an alpha macroglobulin.
