Background: Iodine intake can be measured in various ways, and each method may have advantages and disadvantages. Objective: We sought to investigate the potential associations of various measures of iodine intake with thyroid volume, prevalence of thyroid nodules, and serum thyroglobulin. We also sought to identify, if possible, groups at risk of thyroid disease because of their food choices. ...
Five types of ductile cast irons (DCIs) were fabricated by crystallizers with different inner diameters, as well five austempered (ADIs) after the same isothermal quenching process. The effects amount, diameter, and morphology graphite on mechanical properties DCI ADI effect original as-cast microstructure austempering studied. microstructures characterized optical microscopy, scanning electron...
PURPOSE We aimed to test the hypothesis that medulloblastoma (MB) variants show a different age distribution and clinical behavior reflecting their specific biology, and that MB occurring at very young age is associated with cancer predisposition syndromes such as Gorlin syndrome (GS). EXPERIMENTAL DESIGN We investigated the frequency, age distribution, location, response to treatment, outcom...
Prostate cancer is the second most common cause of cancer death in men in the United States. The most common sites of metastasis include the bone, lymph nodes, lung, liver, pleura, and adrenal glands, whereas metastatic prostate cancer involving the gastrointestinal tract has been rarely reported. A 64-year-old African-American man with a history of prostate cancer presented with anemia. He rep...
Microstructure in graphite nodules plays a fundamental role in mechanical properties in cast iron. Traditional measures used to study spheroid graphite are nodules density, nodularity, volume fraction and mean size. However, sometimes these parameters do not permit a good characterization of the microstructure since they do not allow the discrimination of different regions. In fact, other measu...
http://tag.sagepub.com 749 A 34-month-old boy of Caribbean/Hispanic descent, born abroad and raised in a Houston suburb, following 2 weeks in the Caribbean presented with new-onset painless gagging and vomiting multiple times per day. The emesis contained clear or partially digested food with an occasional bloody tinge. Physical examination and a barium swallow were unremarkable, and trials of ...
Gastritis associated with Helicobacter pylori was present in gastric biopsies from 24/95 (25%) children and adolescents undergoing endoscopy for recurrent abdominal pain and upper gastrointestinal symptoms. H pylori associated gastritis occurred mainly in older children (8-16 years) and was significantly associated with low socioeconomic class and a family history of peptic ulcer disease. Antra...
Dysphagia is an alarm symptom requiring a prompt investigation. Different benign and malignant diseases may present such a symptom. We describe a case of a 79-year-old patient who complained of fluctuating dysphagia episodes following solid food ingestion in the previous 5 months with mild weight loss. No other gastrointestinal symptoms were present. The patient was referred by the General Prac...
The possibility of early superficial Crohn's disease should be considered when mucosal irregularities without transmural abnormalities are seen in the distal 15 cm of the ileum in young patients with protracted symptoms of abdominal pain and diarrhoea. Radiologic assessment of the small bowel is improved using the barium/air double contrast technique and in this study mucosal abnormalities were...
