ABSTRACT
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

Acute appendicitis is the most frequent cause of surgical abdominal emergency. In most of these patients (70 percent) the diagnosis is based on the clinic history and on the physical examination. In those cases the clinic presentation is confusing, the ultrasound with gray scale and high frequency transducers, using the graduated compression technique, has become of great help. It has been reported a sensibility of 84-96 percent with a specificity of 94-98 percent for the diagnostic method. Also lately is has been that the study with color doppler can be useful as help in the diagnosis of appendicitis, demostrating a local increase in the blood flow in the appendicular wall or in the inflammatory mass. However, color doppler by itself acquires its greater usefulness in those cases in which the appendicular size is limit

We report a 35 years old female presenting with a right wrist pain. Physical examination was normal but, on a band X ray examination, multiple dense para-articular bone foci were observed. Studying the rest of the skeleton, similar alterations were found in pelvis, knees, feet, shoulders and elbows. Osteopoikilosis is an infrequent eclerotic bone dysplasia. Its diagnosis is made by the observation of multiple dense, nodular and symmetrical images of para-articular location on bone X ray examinations. It has no clinical or pathological importance. Thus, it must be distinguished from osteoplastic bone metastases

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 presentan dos casos de vesícula doble diagnosticados con ecotomografía. Uno fue comprobado con cirugía demostrándose duplicidad vesicular y de cístico. El otro caso se comprobó con colecistografía oral, demostrándose duplicidad vesicular con cístico común. Se postulan criterios de diagnóstico
