Acute high-altitude illnesses are of great concern for physicians and people traveling to high altitude. Our recent article “Acute Mountain Sickness, High-Altitude Pulmonary Edema Cerebral Edema, a View from the High Andes” was questioned by some sea-level experts. As result this, we answer observations further explain our opinion on these diseases. (HAPE) can be better understood through Oxyge...

The aims of this study were to determine some major biochemical alterations observed in first calving cows with udder edema during the periparturient period and to detect some associations between dietary factors and the disease. For that, the concentrations of some electrolytes (Na(+), K(+), Cl, Ca(2+), P and Mg(2+)), lipid (triglycerides and cholesterol) markers and lipoproteins (HDL, LDL and...

The effects of physiologic and pharmacologic manipulations on contact lens-induced edema were studied. In isolated superfused rabbit corneas bathed in Ringer's solution and covered with large-diameter polymethylmethacrylate (PMMA) lenses, corneal swelling rates of 17-26 microns/hr (versus -5-5 microns/hr in paired controls) were observed. Neither the calcium antagonist diltiazem (10(-4) M), the...

Sutureless, glueless, scleral fixation of an intraocular lens is a known technique of fixing a lens in the scleral pockets. However, this technique is applied to single-piece and toric lenses instead of 3-piece lenses, allowing the advantage of the use of premium lenses in patients with poor capsular support. Favourable results without complications of pigment dispersion, iris transillumination...

PURPOSE To evaluate the prophylactic efficacy of selective laser trabeculoplasty for preventing an increase in intraocular pressure (IOP) after intravitreal triamcinolone acetonide injection. DESIGN Prospective, comparative, interventional case series. METHODS We studied 31 eyes with a baseline IOP of 21 mm Hg or more of 31 patients for which intravitreal triamcinolone acetonide injection w...

BACKGROUND Evening edema of the legs is a physiologic phenomenon occurring after sitting and standing. OBJECTIVE The objective of this study was to investigate which compression pressure is necessary to prevent leg swelling. METHODS In 12 volunteers, the volume of both lower legs was measured in the morning and 7 h later, the difference being defined as evening edema (mL). The procedure was...

BACKGROUND AND OBJECTIVE To assess the role of optical coherence tomography (OCT) in the evaluation and follow-up after vitrectomy for diabetic macular edema. MATERIALS AND METHODS The 18 eyes of 12 patients affected by presumed diabetic vitreous-induced macular edema underwent biomicroscopy with a Goldmann contact lens, fluorescein angiography, and OCT. RESULTS OCT revealed two patterns of...

It is a pleasure to dedicate an issue of Progress in Cardiovascular Diseases to high-altitude medicine, and we gratefully thank the editors for giving us this opportunity. The readers will discover that the frontiers of highaltitude medicine are almost infinite and often extend to low altitude. Why is this so? Progress in medicine is intimately linked with the understanding of underlying mechan...

RATIONALE Most models of acute lung injury in mice have yet to be fully characterized. OBJECTIVES To directly compare and contrast endotoxin and oleic acid models of acute lung injury in mice in terms of their physiologic, biochemical, histopathologic, and imaging manifestations. METHODS Survival studies, lung weights, x-ray computed tomographic scanning, light and electron microscopy, bron...
