BACKGROUND: Corticosteroids (CS) may benefit certain patients with erythromelalgia. OBJECTIVES: Our objective was to determine clinical predictors of corticosteroid-responsive erythromelalgia. METHODS: Patients with erythromelalgia who received CS were identified and stratified into corticosteroid nonresponders (NRs), partial corticosteroid responders (PSRs), complete corticosteroid responders (CSRs), and steroid responders (SRs = PSRs + CSRs)...

INTRODUCTION: Complete denture therapy is one such modality where science and art goes hand in hand. Selection of artificial teeth for completely edentulous patients is not easy in the absence of pre extraction records, because till date concrete guidelines do not exist. AIM: The purpose of this study was to determine if a correlation existed between the visible length of the iris and the length of the maxillary central incisor to potentially provide a guide for teeth selection...

M<sup>2</sup>-factor and root-mean-square (rms) angular width of partially coherent flat-topped (PCFT) beams propagating through inhomogeneous atmospheric turbulence are studied based on the extended Huygens-Fresnel principle and the Wigner distribution function (WDF). It is shown that the effect of turbulence on the PCFT beams can be neglected as the vertical height increases, which is different from the homogeneous turbulence. Analytical formulae of the M<sup>2</sup>-factor and rms angular width of PCFT beams have been given...

In situ fenestration of stent-grafts allows patients with life threatening aortic pathologies to be amenable to emergent "off the shelf indications for use" percutaneous treatments as a bail out technique. Three types of aortic stent-grafts were subjected to laser fenestration in a physiological saline solution followed by balloon angioplasty using 8, 10 or 12 mm in diameter noncompliant balloons. The morphology and the size of fenestrations were observed under optical and scanning electron microscopy. The damage to the fabrics was analyzed and quantified...

R L McKenzie, J B Liley, S Madronich
When the data sets that suggested record high UVI values at Mt Licancabur, and Laguna Blanca, Bolivia are reviewed in full, we find that the reported peak values are incorrect, probably due to instrumental problems. These affect the UVB, UVA and PAR channels at different times and different solar zenith angles, with distinct diurnal patterns in each case. The outliers are consistent with errors that would result from build-up of ice or snow on the surface of the entrance dome, combined with incomplete baffling of light within the integrating spheres that form the entrance optic of these instruments, but we cannot unequivocally attribute them to this cause...

Huai-Ti Lin, Anthony Leonardo
Animals use rules to initiate behaviors. Such rules are often described as triggers that determine when behavior begins. However, although less explored, these selection rules are also an opportunity to establish sensorimotor constraints that influence how the behavior ends. These constraints may be particularly significant in influencing success in prey capture. Here we explore this in dragonfly prey interception. We found that in the moments leading up to takeoff, perched dragonflies employ a series of sensorimotor rules that determine the time of takeoff and increase the probability of successful capture...

INTRODUCTION: and Objectives: Implications of aortic neck dilatation following EVAR are unclear. Previous studies are limited to comparisons of individual, early-generation devices. We compared aortic neck dilatation among contemporary stent-grafts. METHODS: We reviewed pre- and post-op CTA for EVARs performed from 2008-2014. Images were analyzed using 3-D centerline reconstructions. Aortic neck diameter was measured in orthogonal planes at and 10 mm below the lowest renal artery...

The UV environment is a key boundary condition to abiogenesis. However, considerable uncertainty exists as to planetary conditions and hence surface UV at abiogenesis. Here, we present two-stream multilayer clear-sky calculations of the UV surface radiance on Earth at 3.9 Ga to constrain the UV surface fluence as a function of albedo, solar zenith angle (SZA), and atmospheric composition. Variation in albedo and latitude (through SZA) can affect maximum photoreaction rates by a factor of >10.4; for the same atmosphere, photoreactions can proceed an order of magnitude faster at the equator of a snowball Earth than at the poles of a warmer world...

OBJECTIVE/BACKGROUND: Fenestrated endovascular repair (FEVAR) has been used to treat complex abdominal aortic aneurysms (AAAs). The risk of renal function deterioration compared with infrarenal endovascular aortic repair (EVAR) has not been determined. METHODS: Patients with preserved renal function (estimated glomerular filtration rate [eGFR] > 45 mL/minute) enrolled in two prospective, non-randomised studies evaluating Zenith fenestrated and AAA stent grafts were matched (1:2) by propensity scores for age, sex, hypertension, diabetes, and pre-operative eGFR...

OBJECTIVES: Surgeons have multiple grafts options available for the endovascular treatment of abdominal aortic aneurysm (EVAR), and some hypothesize that suprarenal fixation endografts may result in higher rates of renal complications than infrarenal endografts. This study aimed to compare the outcomes of contemporary suprarenal and infrarenal endografts. METHODS: The Targeted Vascular Module of the National Surgical Quality Improvement Project was utilised to identify patients undergoing EVAR for infrarenal aneurysm from 2011 to 2013...

Lead (Pb) is a metal of special importance because of its long history of commercial and industrial use, global atmospheric contamination accelerated by the use of gasoline additives, and health effects, with children being especially vulnerable. Global atmospheric Pb pollution reached its zenith in the 1970's, but subsequent impacts on freshwater aquatic systems are poorly understood. Employing metal-free sampling and handling protocols, we show that snowmelt from the Athabasca bituminous sands region is an insignificant source of dissolved Pb to the Athabasca River (AR)...

Combinations between an angiotensin converting enzyme (ACE) inhibitor or an angiotensin II receptor blocker (ARB) and hydrochlorothiazide (HCTZ) are among the recommended treatments for hypertensive patients uncontrolled by monotherapy. Four randomized, double-blind, parallel group studies with a similar design, including 1469 hypertensive patients uncontrolled by a previous monotherapy and with ≥1 cardiovascular risk factor, compared the efficacy of a combination of a sulfhydryl ACE inhibitor (zofenopril at 30 or 60 mg) or an ARB (irbesartan at 150 or 300 mg) plus HCTZ 12...

BACKGROUND: Fenestrated endografts are customized, patient-specific, endovascular devices with potential to significantly reduce morbidity and mortality of short-neck infrarenal and juxtarenal abdominal aortic aneurysm repair. The Zenith fenestrated endovascular graft (ZFEN) for abdominal aortic aneurysms (Cook Medical, Bloomington, Ind), Food and Drug Administration-approved in 2012, remains the only fenestrated device available in the United States. This technology is among the most technically complex catheter-based procedures and, therefore, inherently associated with serious risk for device-related complications...

Gingival display has been identified as a critical element in a beautiful smile and thus in facial esthetics. The present study aimed to assess the gingival line angle (GLA); the distance between the gingival zenith of maxillary lateral incisor and the gingival line (LID); and the ratio between the height of the proximal contact area (PCA) and crown length, referred to as the proximal contact area proportion (PCAP). Fifty patients, aged 21-30 years, were recruited for study. Maxillary impressions were made using irreversible hydrocolloid and poured in dental stone, and facebow records were used to mount the master casts in an articulator...

OBJECTIVE: Endovascular aneurysm repair (EVAR) becomes the treatment of choice for patients with abdominal aortic aneurysm (AAA). Type I or III endoleak is related to high risk of rupture and reintervention but little is known about the delayed presentation of these. We sought to evaluate the delayed type I or III endoleak after EVAR and assess the early morphological portending factors. METHODS: We retrospectively reviewed a database of 249 patients who underwent endovascular repair with a Zenith AAA stent graft (Cook Medical, Bloomington, Ind) in a single institute from October 2005 to December 2013...
