ABSTRACT
Hematological parameters in newborn umbilical cord blood samples (n = 476), collected at the Hospital Provincial del Centenario, Rosario, were studied. They were divided into 3 groups: (I) full term newborns with weight according to gestational age; (II) low weight and normal gestational age; (III) preterm newborns. The results were as follows: group (I) Hb: 15.5 +/- 1.1 g/dl; RBC; 4.66 +/- 0.33 x 10(12)/l; PCV: 49% +/- 4.3%, MCV 105.1 +/- 5.3 fl; MHC: 33.2 +/- 1.2 pg. Decreased Hb concentration (p < 0.05) and increased MCV (p < 0.01) were observed in preterm newborns in comparison with normal ones, and a slight PCV increase and RBC values in low weight newborns compared to the control group (p < 0.05). Erythrocyte morphology was normal as well as reticulocyte values in these samples. The electrophoretic pattern was (FA) with the following Hb F values 66.3 +/- 6.8%, and Hb A2 0.45 +/- 0.3% in group (I), with a significant increase of Hb F in 30-35 weeks preterm newborns. Group (I) values are considered as normal hematological parameters in newborns in our country, whereas MCV < 94.7 fl is considered as a neonatal microcytosis marker, consequently an alert to investigate alpha-thalassemia. There was no influence on Hb concentration due to maternal smoking habit. The present work could be of relevance for our region since up to the present time there are no similar records.

The experience in upper G.I. tract hemorrhage accumulated during the first 30 months in the Emergency Hemorrhage Unit at the Hospital Posadas is here reported over a total of 428 endoscopies, we found 518 lesions. Ninety one (21%) presented with active bleeding, and 317 (76%) were considered as the probable cause of the bleeding. In 37 cases (8.6%) the site of bleeding was detected, but the diagnosis wasn't done. The most frequent lesions were erosive gastritis (21.2%), gastric ulcer (20%), erosive duodenitis (12.6%), duodenal ulcer (12.15%) and esophageal varices (12.12%) the diagnosis was normal 14.7% of the cases. One hundred and sixty one patients were admitted to the hospital; on 143 (88.82%) patients the original diagnosis was confirmed but it was modified in 18 patients (11.18%) by surgery or repeated endoscopy. During the last 20 months of the period the accuracy diagnostic of the endoscopy increased 95%. When compared with the first 10 months (76%) this fact shows, the importance of the experience acquired by the endoscopist. Most of the patients received medical treatment with a mortality of 9.02% and 25 patients received surgical treatment with a mortality of 28%.

Se resena brevemente la historia y cuadro clinico histologico de los tumores glomicos.Se propone el empleo de la angiografia para los tumores subungueales y profundos por ser mas dificil de abordar para efectuar una biopsia y por tratarse de una tecnica sencilla, con la que se obtienen resultados que confirman el diagnostico y ponen en evidencia la localizacion exacta del tumor. Se describe la tecnica empleada, las imagenes radiologicas que se obtienen y la importancia del signo que denominamos dolor de relleno. Se presentan dos casos personales, en los cuales se llevo a cabo este procedimiento con resultados positivos, que fueron confirmados posteriormente por el estudio histopatologico postoperatorio
