Objectives: Research on the health of workers involved in the cleanup after the attack on the World Trade Center (WTC) on September 11, 2001, has documented high rates of psychological distress and upper gastrointestinal (GI) symptoms. The current article examines the concurrent and longitudinal associations of psychological distress with development of new-onset upper GI symptoms in a large sample of WTC responders.
Methods: A cohort of 10,953 WTC responders monitored by the WTC Health Program participated in the study.
Objectives: To estimate prevalence and assess factors associated with doctor shopping among caregivers of children acutely admitted to a hospital in Hong Kong, and examine the reasons for such behaviour and caregivers' awareness of its possible dangers.
Design: Cross-sectional study with face-to-face surveys.
Setting: A paediatric unit in a teaching hospital in Hong Kong.
Background: Spiral enteroscopy (SE) has emerged as a new alternative for deep intubation of the small intestine. SE is most often used to evaluate abnormal findings on capsule endoscopy (CE).
Objective: Investigate the ability of SE to reproduce abnormal findings detected on preceding CE.
Background & Aims: Preliminary studies performed outside of the United States demonstrated that spiral enteroscopy is safe and effective when performed in young, healthy patients. However, spiral enteroscopy has not been evaluated in a US population of patients with numerous comorbidities. We evaluated the feasibility, efficacy, and safety of spiral enteroscopy in a US population of older patients with multiple comorbidities and a high prevalence of pathologic findings.
