BACKGROUND/AIMS Esophageal stricture is usually managed with outpatient endoscopic dilation. However, patients with food impaction or failure to thrive undergo inpatient dilation. Esophageal perforation is the most feared complication, and its risk in inpatient setting is unknown. METHODS We used National Inpatient Sample (NIS) database for 2007-2013. International Classification of Diseases,...

purpose: to evaluate pupil dilation with intracameral injection of preservative-free lidocaine 1% during phacoemulsification. methods: this interventional case series included 31 consecutive senile cataract patients scheduled for phacoemulsification and intraocular lens (iol) implantation. pupil dilation was achieved using intracameral preservative-free lidocaine 1% without any preoperative or ...

A two-dimensional direction-length framework is a pair (G, p), where G = (V ;D,L) is a graph whose edges are labeled as ‘direction’ or ‘length’ edges, and a map p from V to R. The label of an edge uv represents a direction or length constraint between p(u) and p(v). The framework (G, p) is called globally rigid if every other framework (G, q) in which the direction or length between the endvert...

A novel electronic sensor system is designed to continuously monitor the dilation of the cervix of a pregnant female approaching labour and delivery. The system is capable of wirelessly transmitting the progress of dilation to a central monitoring agency that can get in touch with the attending physician and/or the hospital of the pregnant female. Using wireless telephony, the monitoring agency...

Absfrucl-In this paper, a new technique, the multiple ripple propagation technique, is presented for mapping an h x w grid into a w x h grid such that the dilation cost is 2, i.e., such that any two neighboring nodes in the first grid are mapped onto two nodes in the second grid that are separated by a distance of at most 2. This technique is then used as a basic tool for mapping any rectangula...

The purpose of this study was to test the hypothesis that endothelium-dependent dilation is impaired in soleus resistance arteries from hindlimb-unweighted (HLU) rats. Male Sprague-Dawley rats (300-350 g) were exposed to HLU (n = 14) or weight-bearing control (Con, n = 14) conditions for 14 days. After the 14-day treatment period, soleus first-order (1A) arterioles were isolated and cannulated ...

BACKGROUND AND PURPOSE Potassium channels or nitric oxide or both are major mediators of acidosis-induced dilation in the cerebral circulation. However, these contributions depend on a variety of factors such as species and vessel location. The present study was designed to clarify whether potassium channels and endothelial nitric oxide are involved in acidosis-induced dilation of isolated rat ...

Dilation is a puzzling phenomenon within Imprecise Probability theory: when it obtains, our uncertainty evaluation on event $A$ vaguer after conditioning $B$, whatever $B$ in given partition $\mathcal{B}$. In this paper we investigate dilation with coherent Nearly-Linear (NL) models. These are family of neighbourhood models, obtaining lower/upper probabilities by linear affine transformations (...

Pneumomediastinum following esophageal perforation is a known complication of Eder Puestow dilation for esophageal stenosis. This is the first reported case of esophageal perforation and pneumomediastinum occurring after instrumental self-dilation of a stenotic esophageal lesion. The observed 0.02 percent perforation rate in this patient (compared to the reported 0.3 percent in Eder Puestow "he...
