Effects of Posture and Swallow Volume on Esophageal Motility Morphology and Probability of Bolus Clearance: A Study Using High-Resolution Impedance Manometry.

The Chicago classification diagnostic criteria of esophageal motility disorders are based on 5-ml water swallows in the supine position and have not been analyzed for the correlation between the morphology and bolus transit in the upright position and larger volume swallow conditions. This study aimed to evaluate the effect of posture and swallow volume on peristaltic morphology and the probability of bolus clearance in patients with nonspecific esophageal disorder. A total of 139 patients (4,214 swallows) were included for high-resolution impedance manometry analysis in the right lateral recumbent and upright positions, as well as 5- and 10-ml liquid swallows.

Impact of Endotracheal Intubation on Interventional Endoscopy Unit Efficiency Metrics at a Tertiary Academic Medical Center.

Objectives: Measures for evaluating interventional endoscopy unit efficiency have not been adequately validated, especially in reference to the involvement of anesthesia services for endoscopy. Primary aim was to compare process measures/metrics of interventional endoscopy unit efficiency between intubated and non-intubated patients. Secondary aim was to assess variables associated with the need for endotracheal intubation.

Evaluation of interventional endoscopy unit efficiency metrics at a tertiary academic medical center.

Background And Study Aims: There is an increasing demand for interventional endoscopic services and the need to develop efficient endoscopic units. The aim of this study was to analyze performance data and define metrics to improve efficiency in a single academic interventional endoscopy center. ]

Patients And Methods: The prospective operations performance data (6-month period) of our interventional endoscopy unit (EU) was analyzed.

A pilot study to evaluate the feasibility of implementing a split-dose bowel preparation for inpatient colonoscopy: a single-center experience.

Objectives: Feasibility of using split-dose bowel preparation in an inpatient setting has not been extensively studied. We conducted a single-centre multiphase study to (1) understand the perceived barriers to split-dose administration among nursing and providers, (2) develop and implement a split-dose electronic order set and (3) evaluate the use and impact of split-dose administration on 100 consecutive colonoscopies.

Methods: Nurse/provider interviews were conducted to understand perceived concerns and potential barriers to split-dose preparation.

Congenital rubella syndrome in Haiti (Short communication).

Objective: To determine if there is an unrecognized problem of congenital rubella syndrome (CRS) in Haiti, a country without a national rubella immunization program.

Methods: During March 2001 and June 2001, screening physicals were conducted on approximately 80 orphans at three orphanages in Haiti that accept disabled children. Children were classified as probable CRS cases based on established clinical criteria.
