Perchlorate is known to suppress thyroid function by inhibiting uptake of iodide by the human thyroid at doses of 200 mg/day or greater. A study was conducted to investigate the potential effects of perchlorate in drinking water on thyroid function in newborns and school-age children. A total of 162 school-age children and 9784 newborns were studied in(More)
In Chile, where gallbladder cancer (GBC) rates are high and typhoid fever was endemic until the 1990s, we evaluated the association between Salmonella enterica serovar Typhi (S. Typhi) antibodies and GBC. We tested 39 GBC cases, 40 gallstone controls, and 39 population-based controls for S. Typhi Vi antibodies and performed culture and quantitative(More)
We obtained specimens from the angle of the eye during a trabeculotomy-trabeculectomy operation of a 5-month-old boy with congenital glaucoma. Light and electron miscroscopy of the anterior chamber angle showed the presence of mesodermal tissue covering the entire trabecular area. The trabecular meshwork showed thickening of trabecular beams, and an(More)
Aiming to know the incidence and evolution of major adverse reactions to propylthiouracil in patients with hyperthyroidism, we performed a retrospective analysis of 586 patients treated between 1982 and 1992. All known complications associated to the use of propylthiouracil were considered major adverse reactions, when other causes were discarded. Eight(More)
This work presents a retrieval pipeline and evaluation scheme for the problem of finding the last appearance of personal objects in a large dataset of images captured from a wearable camera. Each personal object is modelled by a small set of images that define a query for a visual search engine.The retrieved results are reranked considering the temporal(More)
BACKGROUND Granulomatous lesions occur in tuberculosis (TB), other infections, toxic, allergic, and autoimmune diseases among others. In absence of a an acid-fast bacilli (AFB) confirmation of TB is necessary. OBJECTIVE To assess the efficacy of PCR for TB detection and to correlate with granuloma histology and AFB staining. METHODS We analyzed 380(More)
Two patients with Cushing's syndrome are reported. The syndrome was the consequence of relapse after transphenoidal resection of a pituitary tumor in one and due to occult ACTH secretion in the other. Determination of ACTH after bilateral petrosal sampling in both cases and after systemic venous sampling at different sites in one, allowed localization of(More)
