Capacity limits in linguistic short-term memory (STM) are typically measured with forward span tasks in which participants are asked to recall lists of words in the order presented. Using such tasks, native signers of American Sign Language (ASL) exhibit smaller spans than native speakers ([Boutla, M., Supalla, T., Newport, E. L., & Bavelier, D. (2004).(More)
CONTEXT Early hospital readmission is emerging as an indicator of care quality. Some children with chronic illnesses may be readmitted on a recurrent basis, but there are limited data describing their rehospitalization patterns and impact. OBJECTIVES To describe the inpatient resource utilization, clinical characteristics, and admission reasons of(More)
BACKGROUND/PURPOSE Appendicitis is one of the most common surgical conditions in children. Laparoscopy has become the standard approach to appendectomy over the past decade. Some critics cite a lack of evidence documenting clear advantages to laparoscopy. To define the pattern of approach compared to outcomes in the United States, we analyzed the Pediatric(More)
IMPORTANCE Postdischarge treatment of acute osteomyelitis in children requires weeks of antibiotic therapy, which can be administered orally or intravenously via a peripherally inserted central catheter (PICC). The catheters carry a risk for serious complications, but limited evidence exists on the effectiveness of oral therapy. OBJECTIVE To compare the(More)
BACKGROUND Few comprehensive pedestrian safety interventions for primary-school-age children have been developed and evaluated. This paper reports the impact of the 3-year (1995-1997) Child Pedestrian In jury Prevention Project (CPIPP) on a cohort of 1603 children followed from age 6 to 9 years. This multicomponent project comprised an educational(More)
A family with osteomesopyknosis is described. This condition is a rare benign bone dysplasia, characterized by patchy sclerosis predominantly involving the axial skeleton. The radiographic appearances may be confused with osteoblastic metastases, renal bone disease and other sclerosing bone disorders. As routine blood tests and isotope bone scans are normal(More)
BACKGROUND White light endoscopy with random biopsies is the standard for detection of intestinal metaplasia (IM) and neoplasia in patients with Barrett's oesophagus (BO). Narrow band imaging (NBI) highlights surface patterns that correlate with IM and neoplasia in BO. OBJECTIVE To compare high-definition white light (HD-WLE) and NBI for detection of IM(More)
BACKGROUND Children with complex chronic conditions depend on both their families and systems of pediatric health care, social services, and financing. Investigations into the workings of this ecology of care would be advanced by more accurate methods of population-level predictions of the likelihood for future hospitalization. METHODS This was a(More)
OBJECTIVE To compare inpatient resource use trends for healthy children and children with chronic health conditions of varying degrees of medical complexity. DESIGN Retrospective cohort analysis. SETTING Twenty-eight US children's hospitals. PATIENTS A total of 1 526 051 unique patients hospitalized from January 1, 2004, through December 31, 2009, who(More)
IMPORTANCE Readmission rates are used as an indicator of the quality of care that patients receive during a hospital admission and after discharge. OBJECTIVE To determine the prevalence of pediatric readmissions and the magnitude of variation in pediatric readmission rates across hospitals. DESIGN, SETTING, AND PATIENTS We analyzed 568,845 admissions at(More)
