Ultrasonography (US) is a rapid, accurate, noninvasive method of evaluating ocular and orbital disease. A wide spectrum of pediatric ocular and orbital disorders can be demonstrated with US: ocular congenital malformations, vitreoretinal disorders, primary and metastatic ocular and orbital neoplasms, inflammatory and congestive disease (focal or systemic),(More)
The usefulness of sonography in evaluating the pancreas in infants and children is well known. Its usefulness is due to the optimal sonic window provided by the relative lack of fat tissue and the large left hepatic lobe in children. A wide spectrum of pancreatic pathologic conditions can be identified sonographically in children, including congenital(More)
Validation of the Coulter LH 750 was carried out in our central hospital laboratory, which processes 1500 hemograms per day for patients admitted into the 4 hospitals of our hospital complex and their corresponding outpatient departments. It is the reference laboratory for the provincial health care area. The analytical quality and the practical use of the(More)
The effects of immobilization on fetal bone development were studied through postmortem radiographs in 11 newborns with congenital neuromuscular diseases (CNMD) of intrauterine onset. Quantitative parameters were determined in the following bones: tibia, femur, humerus, radius, 3rd lumbar vertebra, and 5th rib. Thirty stillborns or newborns of similar(More)
The objective of this study was to evaluate the association of intrahepatic cholestasis, pulmonary stenosis, and hyperlipemia with osseous and renal abnormalities in Alagille's syndrome. A total of 37 patients (25 males and 12 females) with ages ranging between 8 months and 27 years were included. Clinical records as well as radiological and(More)
BACKGROUND/AIM An accurate knowledge of the often complex and unexpected anatomy of conjoined twins is required in order to devise appropriate surgical strategies for separation. The recent progress of imaging techniques prompts an assessment of their contribution to planning separation strategies. MATERIAL AND METHODS From 1990, we treated 8 consecutive(More)
Six children with Shwachman-Diamond syndrome have been diagnosed and treated in our hospital since 1986. We describe the radiological and sonographic findings of this rare disease, which is characterized by metaphyseal chondrodysplasia, neutropenia and exocrine pancreatic insufficiency. It presents with varying extremity shortening, “cup” deformation of the(More)
To assess the relationship between acute viral bronchiolitis and subsequent development of asthma, we studied retrospectively 97 index children, aged between 9 and 14 years, and 52 controls. The bronchiolitis group showed significantly lower values for mean expiratory flow at 50% of vital capacity (MEF50) higher incidence of atopy, and were more sensitive(More)
The volume of the thyroid gland was determined by ultrasonography in 30 preterm infants (27-36 weeks' gestation) born in Madrid. Thyroid gland volume significantly increased (p < 0.01) with postnatal and postmenstrual age and was very well correlated with body weight, height and surface area (p < 0.01). Serum thyroid hormones 3,5,3'-triiodothyronine (T3)(More)
