[Non-specific chronic gastritis and gastric dysplasia, what is their clinical values?]. / Gastritis crónica inespecífica y displasia gástrica, cuál es su valor clínico?

Although nonspecific chronic gastritis and gastric dysplasia are considered as risk factors in the development of gastric cancer, the magnitude of this risk has not been well established. We made an endoscopic and histologic follow-up of 24 patients with an initial diagnosis of atrophic chronic gastritis and some degree of dysplasia over a period of 8 years. The first study revealed slight dysplasia in 8 patients, moderate dysplasia in 13 and severe dysplasia in 3. In our observation, dysplasia considered overall shows a probability of almost 54% of evolution to regression. In our study, the association of atrophic chronic gastritis and severe dysplasia is a reliable marker of gastric cancer. We think it is opportune to carry out periodic follow-ups by endoscopy and biopsy of patients with chronic gastritis and dysplasia.

[Chronic pancreatitis or cancer? Semeiology of pancreatic radiography]. / Pancreatitis crónica o cáncer? Semiología pancreatográfica.

We did a retrospective study of 100 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP), selecting those cases in which the final diagnosis was pancreatitis or pancreatic neoplasm. We analyzed the pancreatic radiographs obtained using this technique and describe the most characteristic diagnostic findings in each case. Results are compared to those published in the medical literature.

Radioinmunoanalisis de adrenalina y noradrenalina en fetos normales a termino. / Radioimmunoanalysis of adrenaline and noradrenaline in normal term fetus

Para establecer los valores promedio de adrenalina y noradrenalina plasmaticos en fetos normales a termino, fueron seleccionados 27 mujeres que cursaron con embarazo normal, a termino por amenorrea y cuyo parto fue eutocico; la respuesta de los recien nacidos fue totalmente fisiologica.A cada uno de los fetos se le tomaron 10 ml de sangue total del cordon umbilical y se determinaron adrenalina y noradrenalina con la tecnica de Yalow y Berson. Los resultados obtenidos fueron para la adrenalina un promedio de 100.3 ng/ml y para la noradrenalina de 85.7. Estadisticamente, se encontro una correlacion positiva entre ambas. Las cifras de adrenalina fetales no fueron influidas por la edad materna, antecedentes de paridad, edad gestacional, peso de los productos o sexo de los mismos. En relacion con la noradrenalina fetal, tampoco influyeron esas variables, excepto en el peso de los productos, pues se observo una ligera tendencia a elevarse, conforme se incrementa el peso de los productos, sin embargo, se requiere de una muestra mayor, para lograr conclusiones definitivas

[Clinical observation in the premature rupture of membranes. Early detection of maternofetal infections]. / Observación clínica en la ruptura prematura de membranas. Detección precoz de infecciones maternofetales.

One hundred patients with term pregnancy, were studied. There were placed in two groups of 50 each; one was the problem group with antecedents and confirmation of premature rupture of membranes; and the other group with intact amnios at the time of delivery, which served as controls. Clinical history, leukocyte count, temperature determination on admission and during trans-partum, leukocyte count in mixed blood from the umbilical cord and clinical surveillance were carried out, until 96 hours after delivery, of mother and child looking for sepsis signs. In the problem group there were 10 cases of maternal infection and 12 of newborns. There were no infections in the control group. There was no perinatal mortality. The most useful examination as to maternal and neonatal infection, was leukocytic count on admission, followed by trans-partum count and maternal temperature. Fetal leukocytic count above 12,500 per mm3 was useful in 70% of the newborns with complications.

Tubal sterilization and ovarian perfusion: selective arteriography in vivo and in vitro.

To determine whether there are changes in the utero-tubo-ovarian circulation after tubal sterilization, selective arteriograms were taken in vivo every 0.3--7.0 seconds with a Puck-type seriograph and also in vitro. A control arteriographic study was made. The operations performed were fimbriectomy and modified Pomeroy. The 30 patients studied were divided into two groups. One was formed by 20 nonpregnant women. The other ten patients were in the early puerperium. Arteriographic images with and without tubal sterilization were prepared, and the different techniques were compared. With the Pomeroy operations, the various tubal sites where surgery was performed were also compared. It was concluded that neither the modified Pomeroy sterilization nor fimbriectomy alters ovarian perfusion in either nonpregnant women or those in the early puerperium.
