This case report documents a rare complication of prostate resection following a Greenlight laser procedure. The 75-year-old gentleman involved underwent photoselective vaporisation of the prostate (PVP) for clinically benign prostatic obstruction. Subsequent to PVP, the patient experienced recurrent macroscopic haematuria and pubic pain. Investigations confirmed the presence of a prostate-symp...

In this work, aqueous diltiazem HCl and polyvinyl-pyrrolidone (PVP) solutions were mixed with Kollicoat SR 30D and spray dried to microparticles of different drug:excipient ratio and PVP content. Co-spray dried products and physical mixtures of drug, Kollidon SR and PVP were tableted. Spray drying process, co-spray dried products and compressibility/compactability of co-spray dried and physical...

Percutaneous vertebroplasty (PVP) has been shown to release spinal pain and stabilize the vertebral body. PVP is suggested as an alternative treatment in spinal metastasis. Although cervical metastases is less prevalent than thoracic and lumbar spine, PVP procedure in cervical vertebrae remains technical challenging. We retrospectively analyzed the data from patients (n = 9) who underwent PVP u...

A glue stick is comprised of solidified adhesive mounted in a lipstick-like push-up tube. Whey is a byproduct of cheese making. Direct disposal of whey can cause environmental pollution. The objective of this study was to use whey protein isolate (WPI) as a natural polymer along with polyvinylpyrrolidone (PVP) to develop safe glue sticks. Pre-dissolved WPI solution, PVP, sucrose, 1,2-propanedio...

PURPOSE To investigate changes in nocturia and predictive factors for improvement after photoselective vaporization of the prostate (PVP) for patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS A total of 103 patients who complained of nocturia of >/=2 times per night on baseline frequency-volume chart (FVC) and who underwent PVP were included in this retrospective study. ...

BACKGROUND In adult living donor liver transplantation (ALDLT), graft-to-recipient weight ratio of less than 0.8 is incomplete for predicting portal hypertension (>20 mm Hg) after reperfusion. We aimed to identify preoperative factors contributing to portal venous pressure (PVP) after reperfusion and to predict portal hypertension, focusing on spleen volume-to-graft volume ratio (SVGVR). METH...

The influence of polyvinylpyrrolidone (PVP), a commonly used binder and adhesive, on the aggregation of spheroids coated with hydroxypropylmethylcellulose (HPMC) was studied. The aggregation propensities of spheroids coated by HPMC alone and by HPMC with polyethylene glycol (PEG) were compared with those coated by HPMC with PVP and the viscosity of the coating solutions determined. The coating ...

BACKGROUND AND PURPOSE The purpose of this study was to determine the efficacy and rate of complications in patients undergoing percutaneous vertebroplasty (PVP) for vertebral compression fractures as a result of secondary osteoporosis caused by long-term corticosteroid use compared with patients with primary osteoporosis treated with PVP. MATERIALS AND METHODS A retrospective review of all p...

Rh NPs coated with a PVP-derived polymer, that combines several distinct protective interactions, exhibit superior thermal and catalytic stability compared to analogue NPs coated with PVP.

BACKGROUND Osteoporotic vertebral compression fractures (OVCFs) are the most common osteoporotic fractures. Pain is the main symptom. Percutaneous vertebroplasty (PVP) is a therapeutic procedure performed to reduce pain in vertebral compression fractures. Numerous case series and several small, non-blinded, non-randomized controlled studies have suggested that vertebroplasty is an effective mea...
