Orthostatic (postural) hypotension (OH) is a common, yet under diagnosed disorder. It may contribute to disability and even death. It can be the initial sign, and lead to incapacitating symptoms in primary and secondary autonomic disorders. These range from visual disturbances and dizziness to loss of consciousness (syncope) after postural change. Evidence based guidelines for the diagnostic wo...

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...

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...

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 ...

OBJECTIVE To explore whether differences between collaboratives with respect to type of topic, type of targets, measures (systems) are also reflected in the degree of effectiveness. STUDY SETTING 182 teams from long-term healthcare organisation developed improvement initiatives in seven quality-improvement collaboratives (QICs) focusing on patient safety and autonomy. STUDY DESIGN Multiple ...

The purpose of the current investigation was to examine the relation between cardioballistic impulse and the fluctuations in continuous isometric force production. Subjects produced isometric force via index finger flexion to constant force targets (0.5, 1 and 2 N) with and without visual feedback while beat to beat blood pressure of their middle finger was recorded. Force fluctuations were qua...

PURPOSE To evaluate treatment of macular edema associated with central retinal vein occlusion (CRVO) using intravitreal triamcinolone acetonide. METHODS Retrospective review of data for 29 eyes of 29 patients with CRVO and macular edema treated with intravitreal triamcinolone acetonide. Initial visual acuity, intraocular pressure, and history of glaucoma were recorded. Final visual acuity, in...

background: parkinson's disease (pd) is a neurodegenerative disorder impairing motor, verbal and other abilities. visual evoked potential (vep) assessment is a useful method for analysis of visual system and its function. the present study was designed in order to evaluate whether vep changes are associated with pd. m aterials and methods: in the present study, 100 subjects encompassing 40 pati...
