Funduscopy:to dilate or not to dilate? [PDF]
BMJ, 2006 Fundoscopy is commonly used by non-ophthalmologists to screen for diabetic retinopathy.1 The sensitivity of fundoscopy through a dilated pupil for detecting diabetic retinopathy is twice as high as detection through an undilated pupil,2 but surveys of general practitioners have found that only 1 in 250 regularly dilate pupils, even when assessing ...

Combinatorics, Probability and Computing, 2009 For k prime and A a finite set of integers with |A| ≥ 3(k − 1)2(k − 1)! we prove that |A + k · A| ≥ (k + 1)|A| − ⌈k(k + 2)/4⌉ where k · A = {ka: a ∈ A}. We also describe the sets for which equality holds.

Electronic Proceedings in Theoretical Computer Science, 2017 In 1973 Paschke defined a factorization for completely positive maps between C*-algebras. In this paper we show that for normal maps between von Neumann algebras, this factorization has a universal property, and coincides with Stinespring's dilation for normal maps into B(H).

Crack Detection of Concrete Images Using Dilatation and Crack Detection Algorithms
Applied Sciences, 2023 Crack detection in structures is an important and time-consuming element of monitoring the health of structures and ensuring structural safety. The traditional visual inspection of structures can be unsafe and may produce inconsistent results.

Nature Reviews Disease Primers, 2019 Dilated cardiomyopathy (DCM) is a clinical diagnosis characterized by left ventricular or biventricular dilation and impaired contraction that is not explained by abnormal loading conditions (for example, hypertension and valvular heart disease) or coronary artery disease.

Survey of Anesthesiology, 1976 Three cases of tracheal dilatation following prolonged ventilation through a tracheostomy tube with a conventional cuff are reported. The routine care of tracheostomies in the ITU at Northampton General Hospital is described. Possible causes for the development of dilatation are suggested and the symptoms and signs discussed.

Navigation-Assisted Balloon Eustachian Tuboplasty for Eustachian Tube Dilatory Dysfunction [PDF]
Clinical and Experimental Otorhinolaryngology, 2020 Objectives. Balloon Eustachian tuboplasty (BET) is a novel treatment method for Eustachian tube dilatory dysfunction (ETD). However, surgeons cannot identify the insertion depth of the catheter during BET, resulting in potential risks such as internal ...
