BACKGROUND Povidone iodine (PVP-I) is a chemical complex of polyvinylpyrrolidone (also known as povidone or PVP) and elemental iodine. Iodine containing compounds are widely and commonly used as antiseptics and disinfectants. They are available in various forms like aqueous solution, tincture, aerosol, ointment, or foam. Skin irritation to them is due to the oxidative effects of iodine. Because...

OBJECTIVE To evaluate the function of percutaneous vertebroplasty (PVP) treatment to pain relief and life quality for patients with spinal tumors. METHODS Articles about the researches on the treatment of spinal tumors by PVP in PubMed, Embase, and the Chinese Biomedical Literature database from January 1, 2015 to December 31, 2013. The keywords "spinal tumors," "efficacy," and "vertebroplast...

INTRODUCTION Since the first case of Middle East Respiratory Syndrome coronavirus (MERS-CoV) infection was reported in 2012, the virus has infected more than 1300 individuals in 26 countries, and caused more than 480 deaths. Human-to-human transmission requires close contact, and has typically occurred in the healthcare setting. Improved global awareness, together with improved hygiene practice...

OBJECTIVE To determine whether patients with acute unilateral peripheral vestibulopathy (PVP), often called "vestibular neuritis/neuronitis or neuropathy" (VN) have a vestibular lesion pattern consistent with the distribution of the neurological afferents. BACKGROUND Much is known about the clinical nature of PVP, however less so about its etiology and pathogenesis. Due to the frequency with ...

Although present in many patients with heart failure and a normal ejection fraction, the role of isolated impairments in active myocardial relaxation in the genesis of elevated filling pressures is not well characterized. Because of difficulties in determining the effect of prolonged myocardial relaxation in vivo, we used a cardiovascular simulated computer model. The effect of myocardial relax...

Over the past several decades, formulation of novel nanofiber-based drug-delivery systems has been a frequent focus scientists around world. Aiming to introduce nanofibrous transdermal system treat pain, nanofiber mats buprenorphine-loaded poly (vinyl pyrrolidone) (Bup/PVP) and poly(vinyl alcohol)/poly(vinyl (Bup/PVP/PVA) were successfully fabricated by electrospinning process for drug delivery...

The effects of storage on the crystallization, dissolution and absorption of tolbutamide from amorphous tolbutamide-2-hydroxypropyl-beta-cyclodextrin (HP-beta-CyD) complex were investigated, in comparison with those of polyvinylpyrrolidone (PVP) solid dispersion. The amorphous solid complex of tolbutamide with HP-beta-CyD and the solid dispersion of tolbutamide with PVP were prepared by a spray...

We addressed the question to which extent cerebral blood flow (CBF) is maintained when, in addition to a high blood viscosity (Bvis) arterial oxygen content (CaO2) is gradually decreased. CaO2) was decreased by hemodilution to hematocrits (Hct) of 30, 22, 19, and 15% in two groups. One group received blood replacement (BR) only and served as the control. The second group received an additional ...

OBJECTIVES To evaluate if povidone-iodine (PVP-I) can be used topically in the treatment of chronic suppurative otitis media-tubotympanic disease and to compare it with ciprofloxacin hydrochloride ear drops. DESIGN Prospective double-blind randomized study. SETTING Academic tertiary medical center. PATIENTS Forty patients with chronic suppurative otitis media were randomized into 2 groups...

BACKGROUND Measurement of central venous pressure (CVP) is a reliable method for evaluating intravascular volume status and cardiac function; however it is an invasive and expensive method that may result in some complications such as arterial puncture, pneumothorax and development of infections. This study was performedto compare CVP measurements between central and peripheral catheters in inf...
