An intravertebral vacuum cleft (IVC) is not an uncommon finding; it is more likely to occur in patients with osteoporotic vertebral compression fractures (OVCF). There are scarce data on the treatment of these patients with percutaneous balloon kyphoplasty (PKP). Between August 2005 and March 2010, 35 single vertebral fracture patients with an IVC sign were treated by PKP. Visual Analogue Score...

Perintah Kawalan Pergerakan (PKP) telah dilaksanakan secara berperingkat iaitu bermula 18 Mac 2020 di bawah Akta Pencegahan dan Pengawasan Penyakit Berjangkit 1988 Polis 1967 (Ashley Tang 2020) tindakan undang-undang akan dikenakan kepada mereka yang gagal mematuhi arahan PKP (Kementerian Kesihatan Malaysia 2020). Salah satu kandungan adalah penutupan semua institusi pendidikan selaras dengan s...

We consider the 0–1 Penalized Knapsack Problem (PKP). Each item has a profit, a weight and a penalty and the goal is to maximize the sum of the profits minus the greatest penalty value of the items included in a solution. We propose an exact approach relying on a procedure which narrows the relevant range of penalties, on the identification of a core problem and on dynamic programming. The prop...

Aim—To study the use of penetrating keratoplasty (PKP) for the treatment of severe fungal keratitis that could not be cured by antifungal medication. Methods—A retrospective analysis of 108 cases of severe fungal keratitis in which PKP was performed served as the basis for this study. Fungal keratitis was diagnosed by KOH staining of corneal scrapings or by confocal microscopic imaging of the c...

Differential inner core rotation was first detected from time-dependent observations of differential travel times between PKP(DF) waves (which go through the inner core) and PKP(BC) waves (which turn at the bottom of the outer core) (Song and Richards, 1996). Criticisms concerning the reported detection have been raised, the most significant one being the possible bias from potential systematic...

BACKGROUND Percutaneous kyphoplasty (PKP) could achieve rapid pain relief for older patients with osteoporotic vertebral compression fractures (OVCFs). Bone cement in PKP was the key factor keeping the stabilization of the vertebral body. However, the same amount of cement can distribute differently in a vertebral body and can thereby result in different surgery outcomes. Therefore, the volume ...
