A case of electrocardiographic artifact due to mobile a phone mimicking ventricular tachycardia was presented. The artifact was discriminated by close scrutiny of ECG and was attributed to a mobile phone because it was simultaneous with mobile phone game. © 2014 Elsevier Inc. All rights reserved.

Purpose The purpose of the present study was to compare a newly developed chitosan-collagen membrane (CCM) with a standard collagen membrane (SCM) regarding their effects on guided bone regeneration. Materials and Methods The right mandibular premolars and first molar were extracted from 12 beagle dogs. Four months later, acute buccal dehiscence-type defects (4 × 3 mm in height and width) were surgically created after implant site preparation. The defects were randomly assigned to 4 different groups: CCM-1 (weight ratio of chitosan to collagen of 40:1), CCM-2 (weight ratio of chitosan to collagen of 20:1), SCM, and vehicle control. The dogs were sacrificed after 4, 8, and 12 weeks of healing for radiographic examination, histologic observation, and histometric analysis. Results The membrane-treated sites showed more bone formation than the control sites, although no statistically significant differences were found between the membrane-treated sites and the control sites for new bone-to-implant contact and new bone-filled area at any point. At 8 weeks, the new bone height for the membrane-treated sites was significantly greater statistically than that of the untreated group (P <.05). At 12 weeks, the CCM-1 group showed significantly greater new bone height (1.91 ± 0.25 mm) than the untreated group (1.20 ± 0.34 mm; P <.05). However, the CCMs did not show any statistically significant differences compared with the SCMs for any assessed parameter. Conclusions The results of the present study have shown that the developed CCMs can enhance bone regeneration and could be a candidate for use in guided bone regeneration. © 2014 American Association of Oral and Maxillofacial Surgeons.

Keratitis caused by Pseudomonas aeruginosa is a potentially vision-threatening condition that requires prompt treatment to prevent vision loss. The recognition of infectious agents by the Toll-like receptor (TLR) system initiates primary innate and later adaptive immune responses. In this study, in late cases of corneal P. aeruginosa infection, the expression of TLR2, 4, 5 and 9 mRNA were all upregulated. In early infection cases, only TLR9 mRNA expression was upregulated. In late cases, the protein expression of TLR2, 4, 5, 9 and pIκB-α were elevated. In early cases, only TLR9 and pIκB-α expression were upregulated. Concentrations of IL-6 and IL-8 increased in infected corneas, especially in late cases. Myeloperoxidase (MPO) activity suggested that polymorphonuclear leukocyte (PMN) numbers were higher in late than in early stages of infection. The delayed response of TLRs may explain why P. aeruginosa infection exacerbates rapidly at the early infection stage. This finding may have important implications for the treatment of innate immunologic responses to corneal infections. © 2009 Springer-Verlag.

Background/Aims: To systematically evaluate the effect and safety of octreotide on primary moderate to severe acute pancreatitis. Methodology: The Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, PubMed, EMBASE, Science Citation Index Expanded (SCI-E), and Chinese Biomedicine Database (CBM) were searched in September 2011. Major outcomes contained mortality, incidence rate of complications, rate of surgical intervention, and length of hospital stay. Results: Eleven randomized clinical trials with 720 participants were included and evaluated, only two of which had a high study quality and were combined in meta-analysis. The pool estimate of RR of mortality was 0.88 (95% CI: 0.53, 1.45) and that of incidence rate of complication was 1.08 (95% CI: 0.94, 1.26), both of which had no significant difference. The other two outcomes could not be combined for lack of enough data. Conclusions: Present evidence does not approve octreotide's benefit in the major outcomes of moderate to severe acute pancreatitis and further randomized controlled trials with high quality and large sample size are required. © H.G.E.

We developed a maternal fetal rat model to study the effects of isoflurane-induced neurotoxicity on the fetuses of pregnant rats exposed in utero. Pregnant rats at gestational day 14 were exposed to 1.3 or 3% isoflurane for 1 h. At postnatal day 28, spatial learning and memory of the offspring were examined using the Morris Water Maze. The apoptosis was evaluated by caspase-3 immunohistochemistry in the hippocampal CA1 region. Simultaneously, the ultrastructure changes of synapse in the hippocampal CA1 and dentate gyrus region were observed by transmission electron microscopy (TEM). The 3% isoflurane treatment group showed significantly longer escape latency, less time spent in the third quadrant and fewer original platform crossings in the Morris Water Maze test, significantly increased number and optical densities of caspase-3 neurons. This treatment also produced remarkable changes in synaptic ultrastructure compared with the control and the 1.3% isoflurane groups. There were no differences in the Morris Water Maze test, densities of caspase-3 positive cells, or synaptic ultrastructure between the control and 1.3% isoflurane groups. High isoflurane concentration (3%) exposure during pregnancy caused spatial memory and learning impairments and more neurodegeneration in the offspring rats compared with control or lower isoflurane concentrations. © 2012 Elsevier Inc.
