Evaluation of the reasons for preferring root canal treatment in mature permanent teeth potentially indicated for pulp preservation: a clinical case/photo-based questionnaire study.

Background: With advances in pulp preservation procedures (PPP), indications for PPP extend to exposed pulp with symptoms in teeth with carious lesions. Scenario/text-based questionnaire studies report a high preference for PPP for exposed pulp with no pulpal symptoms. However, negative perceptions towards PPP for exposed pulp in carious teeth are prevalent among dentists.

Long-Term Outcomes of Renal Function After Adult Intestinal Transplantation at a Single Small-Volume Center: 2 Cases of Renal Transplantation.

Purpose: Renal dysfunction more frequently occurs after intestinal transplantation (ITx) than after heart, lung, or liver transplantation. We provide a clinical analysis of renal function after adult ITx.

Methods: We retrospectively analyzed 8 adult ITx patients who survived for at least 6 months between 2004 and 2018.

Kidney transplantation using expanded criteria deceased donors with terminal acute kidney injury: a single center experience in Korea.

Purpose: We investigated the clinical outcomes of deceased donor kidney transplantation (KT) using kidneys with terminal acute kidney injury (AKI).

Methods: Between February 2000 and December 2013, we performed 202 deceased donor renal transplants from 159 brain dead donors. According to the expanded criteria donor (ECD) and AKI network criteria, we divided 202 recipients into 4 groups: Group I: Non-AKI & standard criteria donor (SCD) (n = 97); group II: Non-AKI & ECD (n = 15); group III: AKI & SCD (n = 52); and group IV: AKI & ECD (n = 38).

Evaluation of soft tissue asymmetry using cone-beam computed tomography after open reduction and internal fixation of zygomaticomaxillary complex fracture.

Objectives: In this study, we assessed soft tissue asymmetry that occurred after open reduction of unilateral zygomaticomaxillary complex (ZMC) fractures. We proposed a simple method to assess soft tissue asymmetry after reduction surgery by evaluating the symmetry between the affected and the unaffected sides. The factors affecting soft tissue contour after surgery were also analyzed.

Effects of low-dose IV ketamine on peripheral and central pain from major limb injuries sustained in combat.

Objective: Examine response patterns to low-dose intravenous (IV) ketamine continuous infusions on multiple pain outcomes, and demonstrate effectiveness, safety, and tolerability of ketamine administration on general wards.

Design: Retrospective case series of consecutive patients given low-dose IV ketamine continuous infusions.

Setting: Walter Reed Army Medical Center, Washington, DC.

The effect of lipid emulsion infusion on postmortem ropivacaine concentrations in swine: endeavoring to comprehend a soldier's death.

Background: Lipid emulsion (20%) is advocated as a rescue drug for local anesthetic toxicity. No study has measured the impact of lipid emulsion therapy on postmortem local anesthetic serum levels.

Methods: We anesthetized Yorkshire swine (n = 11) and standard monitors were placed.

Double-blinded, placebo-controlled, prospective randomized trial evaluating the efficacy of paravertebral block with and without continuous paravertebral block analgesia in outpatient breast cancer surgery.

Background: Paravertebral block (PVB) is an effective alternative to general anesthesia for breast cancer surgery. Continuous paravertebral block (CPVB) anesthesia may extend postoperative analgesia at home and improve quality of early postoperative recovery of breast cancer patients.

Purpose: This double-blinded randomized trial was conducted to compare degree of pain, nausea, mood, level of symptom distress, and time to return to normal daily activity between PVB and PVB + CPVB in patients undergoing outpatient breast cancer surgery.

Serum ropivacaine concentrations and systemic local anesthetic toxicity in trauma patients receiving long-term continuous peripheral nerve block catheters.

Background: Ropivacaine is a long-acting local anesthetic used frequently for peripheral nerve blocks and continuous peripheral nerve block catheters. Combat trauma patients at Walter Reed Army Medical Center often receive continuous peripheral nerve block catheters as part of their pain regimen. These catheters remain in situ for several days to weeks.

Advanced regional anesthesia morbidity and mortality grading system: regional anesthesia outcomes reporting (ROAR).

Objective: A regional anesthesia complication grading system (regional anesthesia outcomes reporting [ROAR]) was developed and applied to 1,213 consecutive patients over a 14-month period. The goal of the project was the creation of a system to standardize complication reporting in the regional anesthesia literature.

Design: Patient demographics, status as a war casualty, regional block procedure-specific details, and complication grade were entered into an Internet-based, encrypted Department of Defense database.

Standard versus pH-adjusted and lidocaine supplemented radiocolloid for patients undergoing sentinel-lymph-node mapping and biopsy for early breast cancer (PASSION-P trial): a double-blind, randomised controlled trial.

Background: Sentinel-lymph-node (SLN) mapping and biopsy maintains staging accuracy in early breast cancer and identifies patients for selective lymphadenectomy. SLN mapping requires injection of technetium-99m-sulfur colloid-an effective but sometimes painful method, for which better pain-management strategies are needed. In this randomised, double-blind trial, we compared degree of pain between standard radiocolloid injection and pH-adjusted and lidocaine-supplemented formulations for patients undergoing SLN mapping for breast cancer.

Optimal microbial adaptation routes for the rapid degradation of high concentration of phenol.

Pseudomonas fluorescence KNU417 was able to degrade up to 700 mg/L of phenol in 65 h but could not degrade 1,000 mg/L of phenol. Phenol degradation rate was noticeably enhanced by pre-adaptation. In addition, the cell was able to degrade up to 1,300 mg/L of phenol by pre-adapting to 700 mg/L of phenol.

Comparison between entrapment methods for phenol removal and operation of bioreactor packed with co-entrapped activated carbon and Pseudomonas fluorescence KNU417.

A microorganism capable of degrading phenol was isolated from crude oil contaminated soil and identified as Pseudomonas fluorescence. A porous polymer bead of polyvinyl alcohol (PVA) and Xanthan gum was found to be the best entrapment for phenol degradation in terms of bead shape (spherical form), bead strength, non-agglomeration, phenol degradation rate, and cell holding inside the bead. Activated carbon was co-immobilized with the microorganism in the bead, which readily adsorbed phenol to decrease initial phenol concentration.

Protein phosphorylation analysis by site-specific arginine-mimic labeling in gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

Although recent advances in gel electrophoresis and mass spectrometry have greatly facilitated separation, purification, and identification of proteins, significant challenges remain in relation to phosphoprotein analysis. Here we introduce a powerful method for analysis of protein phosphorylation in which phosphorylation sites are labeled with guanidinoethanethiol (GET) by beta-elimination/Michael addition prior to proteolysis and mass spectrometry (MS) analysis. This technique is especially useful in conjunction with gel-based technology in that all of the processes involved, including GET labeling, washing, and phosphospecific enzymatic hydrolysis, can be carried out in excised gel slices, thereby minimizing sample loss and contamination.

[Meta-analysis of the research findings concerning functional relationships of explanatory variables to hope].

Purpose: The purpose of the study was to meta-analyze the relationships of major concepts, which were made by synthesizing similar explanatory variables into more comprehensive concepts, to hope.

Method: The relevant researches from Jan 1980 to Dec 2003, performed in adults or adult patients, were collected. Using the SAS program, meta-analysis were done with the input data of the number of subjects, the correlation coefficients provided from most of the studies or a few transformed correlation coefficients from F value.
