We propose an augmented reality system to identify lumbar vertebral levels to assist in spinal needle insertion for epidural anesthesia. These procedures require careful placement of a needle to ensure effective delivery of anesthetics and to avoid damaging sensitive tissue such as nerves. In this system, a trinocular camera tracks an ultrasound transducer(More)
BACKGROUND Milligan-Morgan excision haem-orrhoidectomy remains a very popular treatment modality for third and fourth degree haemorrhoids due to its cost effectiveness and good long-term results. The LigaSure tissue-sealing device is an alternative technique used in haemorrhoidectomy that has been shown to produce favourable results. The aim of this study(More)
Custom devices supporting bone regeneration and implant placement are needed for edentulous patients with large mandibular deficiencies where endosteal implantation is not possible. We developed a novel subperiosteal titanium-aluminum-vanadium bone onlay device produced by additive manufacturing (AM) and post-fabrication osteogenic micro-/nano-scale surface(More)
We investigated the clinical characteristics and outcomes of 43 patients with Acinetobacter junii bacteremia at a 2,500-bed tertiary care center in northern Taiwan. These organisms were confirmed to the species level by an array assay and 16S rRNA gene sequence analysis. The antimicrobial susceptibilities of the 43 A. junii isolates to 13 agents were(More)

Background: Toll-like receptors (TLRs) are transmembrane receptors that activate cells of the innate immune systems upon recognition of pathogen-associated molecular patterns. The TLR4 is an essential component of the innate immune response to various microorganisms. We investigated the impact of TLR4 polymorphism on development of opportunistic diseases in(More)
