Increasingly, postoperative cognitive dysfunction (POCD) is recognized as a complication after surgery in the elderly; but it's etiology remains unclear. Here we examine changes in cytokine levels during both the pre-operative and postoperative period, comparing them with long term variation in cognitive test scores. Forty-one patients aged 65 and older undergoing major surgery with general anesthesia were recruited after written consent in this IRB approved study. Thirty went on to complete this prospective, non-interven-tional and non-randomized study...

BACKGROUND: A better understanding of the blood supply of the femoral head is essential to guide therapeutic strategies for patients with femoral neck fractures. However, because of the limitations of conventional techniques, the precise distribution and characteristics of intraosseous arteries of the femoral head are not well displayed. QUESTIONS/PURPOSES: To explore the characteristics and interconnections of the intraosseous vessel system between different areas of the femoral head and the possible blood supply compensatory mechanism after femoral neck fracture...

A 58-year-old man presented with slowly progressive chemosis, exophthalmos, and blepharedema of the left eye. Digital subtraction angiography revealed multiple dural arteriovenous fistulas(dAVFs)involving the bilateral tentorium, superior sagittal sinus, and right frontal convexity. In addition, occlusion of the left cavernous sinus and left sigmoid sinus were observed, which could lead to venous hypertension and might be associated with the occurrence of multiple dAVFs. Along with the congestion of the left ophthalmic vein, increased intracranial pressure due to the left tentorial dAVF with cortical venous reflux could have caused the left eye symptoms; therefore, the tentorial lesion was treated first...

This article describes the computer-aided design/computer-aided manufacture (CAD/CAM) accuracy of dental drill guides for application in guided surgery. Today, the availability of three-dimensional (3D) desktop printers allows for the cost-effective production of drill guides by dental laboratories. Our investigations show the accuracy of produced guides by eliminating influencing factors that exist in the guided surgery workflow. To investigate this accuracy, a method was developed to evaluate the CAD/CAM production technology apart from sources of error from cone beam computed tomography (CBCT) scans, intraoral scans, software or human error...

Digital technology has been widely used in the field of implant dentistry. From a surgical standpoint, computer-guided surgery can be utilized to enhance primary implant stability and to improve the precision of implant placement. From a prosthetic standpoint, computer-aided design/computer-assisted manufacture (CAD/CAM) technology has brought about various restorative options, including the fabrication of customized abutments through a virtual design based on computer-guided surgical planning. This case report describes a novel technique combining the use of a three-dimensional (3D) printed surgical template for the immediate placement of an implant, with CAD/CAM technology to optimize hard and soft tissue healing after bone grafting with the use of a socket sealing abutment...

OBJECTIVE: Restoration of the philtral region following traumatic, cleft, and tumor surgeries is often difficult due to influence of this feature to whole facial beauty. The aim of this study is to investigate the types and measurements of the philtrum and its relationship with the upper lip using a software. METHODS: Standard personal photographs of the philtral region were obtained from 200 young adults participated in this study. Linear analyses (the lengths of philtral column and dimple; the philtral width) and angular analyses (apex and central angles of Cupid's bow) were measured as reference points...

BACKGROUND: The aim of this meta-analysis and systematic review of published evidence was to optimize chest tube management for fast-track rehabilitation of lung cancer patients after video-assisted thoracic surgery (VATS). METHODS: The PubMed, Web of Science, and EMBASE databases were searched to identify all studies that addressed the issue of chest tube management after VATS for lung cancer. Finally, 35 articles were included for analysis, i.e., 29 randomized controlled trials and 6 clinical trials...

PURPOSE: To evaluate a new nuclear cataract grading system which is intended as a surgical guidance system to predict lens hardness before cataract surgery. METHODS: The new BCN 10 grading system consists of frontal and cross-sectional slit-lamp images of human eye lenses, ranging from a completely transparent lens nucleus to a totally black nuclear cataract. Validation was done with 9 observers for 110 cases. Two modalities were applied, and observers were asked to use only whole digits and then half digits for grading...

PURPOSE: The purpose of this study was to evaluate the difference in the center position of the ACL footprint based on grid placement using the quadrant method according to the morphological variations of the Blumensaat's line. METHODS: Fifty-nine non-paired human cadaver knees were used. The ACL was cut in the middle, and the femoral bone was cut at the most proximal point of the femoral notch, and the digital images were evaluated using Image J software. The femoral ACL footprint was periphery outlined and the center position was automatically measured...

Multiplexed immunofluorescent testing has not entered into diagnostic neuropathology due to the presence of several technical barriers, amongst which includes autofluorescence. This study presents the implementation of a methodology capable of overcoming the visual challenges of fluorescent microscopy for diagnostic neuropathology by using automated digital image analysis, with long term goal of providing unbiased quantitative analyses of multiplexed biomarkers for solid tissue neuropathology. In this study, we validated PTBP1, a putative biomarker for glioma, and tested the extent to which immunofluorescent microscopy combined with automated and unbiased image analysis would permit the utility of PTBP1 as a biomarker to distinguish diagnostically challenging surgical biopsies...

BACKGROUND: The Kymerax© Precision-Drive Articulating Surgical System by Terumo© is a handheld laparoscopic robot which permits motion in two additional degrees of freedom (deflection and rotation in the instrument tip). In a pelvitrainer model, we compared the performance of participants with different laparoscopic experiences and compared Kymerax© to conventional laparoscopic instruments. METHODS: 20 expert surgeons, performing more than 50 laparoscopic procedures per year, and 25 medical students without any experience in surgery at all were selected...

BACKGROUND: We hypothesize that surgery for moderate-to-severe camptodactyly (>50 degrees) results in modest gains in range of motion and improved digital position. METHODS: A retrospective analysis of patients undergoing surgery for camptodactyly at a tertiary children's hospital between 2000 and 2014 was performed. Surgery was indicated for patients with persistent, functionally limiting flexion contractures despite observation, therapy, and splinting. Data were collected on demographics, clinical history and presentation, nonoperative management, surgery, and clinical follow-up, focusing on range of motion at the involved joint...

PURPOSE: We aimed to compare the clinical and radiographic results of patients with a mallet fracture involving more than one-third of the articular surface, but without a high degree of distal interphalangeal (DIP) joint subluxation, treated with extension block pinning or nonsurgical management. METHODS: Forty-nine patients with a mallet fracture involving more than one-third of the articular surface were reviewed. Twenty-six cases were treated using extension block pinning (surgery group) and 23 were treated nonsurgically (nonsurgical group)...

The clinical value of routine postoperative radiographic evaluation after orthopedic procedures has recently been called into question. The objective of the present investigation was to evaluate the ability of foot and ankle surgeons to accurately and reliably assess postoperative radiographs after first metatarsal-phalangeal joint arthrodesis. Thirty sets of digital radiographs from 11 patients who had undergone first metatarsal-phalangeal joint arthrodesis were retrospectively evaluated by 5 podiatric physicians board-certified in foot surgery...
