BACKGROUND Interface pressure is a key risk factor in the development of pressure ulcers. Visual feedback of continuous interface pressure between the body and support surface could inform clinicians on repositioning strategies and play a key role in an overall strategy for the prevention and management of pressure ulcers. METHODS/DESIGN A parallel two-group randomized controlled clinical tri...

BACKGROUND The purpose of this study was to evaluate the effects of topical nipradilol monotherapy for 5 years on intraocular pressure, visual field performance, and optic disk topography. METHODS Thirty patients with normal tension glaucoma were monitored for intraocular pressure every 1-3 months. A Humphrey visual field test and measurement of optic disk configuration using the Heidelberg r...

OBJECTIVE To explore the effect of visual and haptic vertical stimulation on standing balance in post-stroke patients. METHODS Twenty-five post-stroke patients were recruited. We measured left/right standing pressure differences and the center of pressure (COP) parameters for each patient under three different conditions: no stimulation, visual, and haptic stimulated conditions. First, patien...

carbon dioxide flooding is considered to be one of the most effective enhanced oil recovery methods for the light oil reservoirs. depending on the operating pressure, the process might be miscible or immiscible. minimum miscibility pressure (mmp) is the most important parameter for assessing the applicability of any miscible gas flood for an oil reservoir. the miscibility condition is determine...

Intracameral tissue plasminogen activator (t-PA) application in a child with previously unrecognized sickle cell anemia, post-traumatic hyphema, thrombosis in trabecular mashwork and consecutive acute glaucoma showed positive results. Thirteen year-old boy, son of African father and Caucasian mother, was admitted to hospital, with symptoms of acute glaucoma and partial hyphema after right eye t...

abstract introduction: primary dysmenorrhea is common in women during reproductive age. objective: this study aimed to determine the effect of acupressure on sixth spleen point (sp6) on relief of primary dysmenorrhea. methods: this study is a clinical trial. students with primary dysmenorrheal living in dormitory were studied during three menstrual cycles. pain intensity was measured on the fir...

This article represents the fourth case in literature of an association between pseudotumor cerebri (PTC) and leuprolide acetate, the first with precocious puberty and severe visual loss. A 9-year-old girl with precocious puberty was treated with a once-monthly dose of leuprolide acetate (3.75 mg) for three months. In the 4th month of treatment, it was decided to increase the dosage of leuproli...

The glaucomas are a group of eye diseases characterized by progressive ganglion cell and optic nerve damage, leading to constriction of the visual fields and eventual loss of central vision. Although the disease is typically associated with increased intraocular pressure (IOP), there are patients with lowor normal-tension glaucoma and others with elevated IOP who do not experience optic nerve d...

We compare and contrast measurements of the mass accommodation coefficient of water on a water surface made using ensemble and single particle techniques under conditions of supersaturation and subsaturation, respectively. In particular, we consider measurements made using an expansion chamber, a continuous flow streamwise thermal gradient cloud condensation nuclei chamber, the Leipzig Aerosol ...

AIMS This study describes a prospective consecutive case series of the initial six eyes of five patients undergoing implantation of the trabecular bypass tube shunt. METHODS A prospective consecutive case series. The initial six eyes of five patients with uncontrolled open angle glaucoma who had never previously undergone ocular surgery. Implantation of the trabecular bypass tube shunt measur...
