BACKGROUND Malignant astrocytomas of the spinal cord are uncommon neoplasms with a dismal prognosis. To the authors' knowledge, little information has been published to date regarding the prognostic impact of clinicopathologic factors. METHODS The authors studied 36 cases to investigate the prognostic effect of the World Health Organization (WHO) tumor(More)
INTRODUCTION Residual symptoms such as fatigue, cognitive limitations, and emotional distress can be experienced by cancer survivors. These symptoms may impact their abilities at work. It is unclear to what degree these symptoms are associated with work in occupationally active breast cancer survivors, the most prevalent cancer survivor group. METHODS A(More)
OBJECT The occurrence of meningiomas in children younger than 20 years of age is rare, accounting for less than 3% of all childhood tumors of the central nervous system. The authors of this study sought to add to the limited available information regarding clinicopathological factors that influence outcome, disease progression, and survival in children with(More)
Loss of control (LOC) eating in youth is associated cross-sectionally with eating-related and psychosocial distress and is predictive of excessive weight gain. However, few longitudinal studies have examined the psychological impact and persistence of pediatric LOC eating. We administered the Eating Disorder Examination and self-reported measures of(More)
Gastritis, peptic ulcer disease, and gastric cancer are a few of the diverse disease manifestations that have been shown to be associated with infection by Helicobacter pylori. Why some individuals develop more severe forms of disease remains largely unknown. In this study, 225 South Korean strains were genotyped for vacA and then analyzed to determine if(More)
The fucosylated ABH antigens, which constitute the molecular basis for the ABO blood group system, are also expressed in salivary secretions and gastrointestinal epithelia in individuals of positive secretor status; however, the biological function of the ABO blood group system is unknown. Gastric mucosa biopsies of 41 Rhesus monkeys originating from(More)
CONTEXT Patients previously treated with desiccated thyroid extract (DTE), when being switched to levothyroxine (L-T₄), occasionally did not feel as well despite adequate dosing based on serum TSH levels. OBJECTIVE Our objective was to investigate the effectiveness of DTE compared with L-T₄ in hypothyroid patients. DESIGN AND SETTING We conducted a(More)
Primary extracranial meningiomas are rare neoplasms, frequently misdiagnosed, resulting in inappropriate clinical management. To date, a large clinicopathologic study has not been reported. One hundred and forty-six cases diagnosed between 1970 and 1999 were retrieved from the files of the Armed Forces Institute of Pathology. Histologic features were(More)
OBJECTIVE Fibromyalgia (FM) and chronic fatigue syndrome (CFS) are associated with substantial physical disability. Determinants of self-reported physical disability are poorly understood. This investigation uses objective ambulatory activity monitoring to compare patients with FM and/or CFS with controls, and examines associations of ambulatory activity(More)
OBJECTIVE Our objective was to prospectively compare colonic distention and patient comfort at screening CT colonography (CTC) with patient-controlled room air (RA) insufflation versus automated carbon dioxide (CO2) delivery. SUBJECTS AND METHODS Two hundred eight adults undergoing CTC were randomized to RA or CO2 (104 per method). Colonic distention was(More)
