RESUMO
To determine the prevalence of thyroid nodules in the healthy population, ultrasonography (US) of the thyroid gland was performed in 144 persons (72 women and 72 men), aged 15-72 years with average 35 years, in and urban area of Santiago de Chile where goiter is not considered endemic. Subjects with any previous thyroid were excluded. 59 por ciento had normal nutritional state, 15,3 por ciento were slim and 25,7 por ciento were obeses. Thirty thyroid nodules were founded in 21 (14,6 por ciento) subjects: 15 female and 6 male. Thirteen (9 por ciento) subjects had solitary nodules and 8 (5,6 por ciento) had multiple nodules. 12 nodules were solid. The mayority of the people with nodules (16 of 21) were subjects of normal weight, 1 nodule was founded in slim and 4 in obeses. The results are in accordance with other studies indicating that focal nodular changes of the thyroid gland are common in healthy population and with more frequency in women. Besides the nodules with old age. The frequency of the nodules in our group was less than other studies, because our population was younger

The aim of this work was to perform ultrasonographic measurement of normal pancreas in the chilean population. Among 5000 subjects referred for an ultrasound abdominal examination, those without history of alcoholism, pancreatitis or liver disease were selected for the study. 261 individuals (157 female) aged 20 to 79 years were studied. The size of the head of the pancreas ranged from 6 to 28 mm (17.7ñ4.2 mm), the body size ranged from 4 to 23 mm (10.1ñ3.8 mm) and the tail size from 5 to 28 mm (16.4ñ4.2 mm). These figures are lower than those reported in Europe and North America. No sizw differences were observed according to sex or body frame. Progressive declines in size with age, were observed in all pancreatic segments. No hypoecogenic pancreas were observed. A new technique to improve pancreatic ultrasonographic vision is proposed

Se realizó un estudio prospectivo en un grupo de 25 embarazadas adolescentes a las que se les practicó una determinación única de la relación sístole-diástole (S/D) con doppler continuo de arterias arcuatas a ambos lados del útero desde la semana 16 de amenorrea en adelante. Se estableció la relación entre los resultados de la velocimetría doppler y el peso del recién nacido (RN). Hubo 7 RN pequeños para la edad gestacional (PEG). La sensibilidad del método fue 94,4%, la especificidad 57,1%, el valor predictivo positivo 80,0% y el valor predictivo negativo 85,0%. Se destaca la importancia de la determinación de ambas arcuatas y de la influencia de la ubicación placentaria en los resultados
