BACKGROUND: Intraoperative instrument recounts are performed to avoid retained foreign surgical items. These additional counts, however, beget risks of their own, including prolonged operative times, exposure to radiation, and increased cost. Our study aimed to identify factors that increase the likelihood of instrument recounts during plastic surgery procedures, and use our findings to guide potential solutions for preventing unnecessary recounts across all surgical fields. STUDY DESIGN: This is a retrospective review of all plastic surgical cases in the main operating setting at New York University Langone Medical Center (NYULMC) between March 2014 and February 2015...

Implementing a robotic urological surgery program requires institutional support, and necessitates a comprehensive, detail-oriented plan that accounts for training, oversight, cost and case volume. Given the prevalence of robotic surgery in adult urology, in many instances it might be feasible to implement a pediatric robotic urology program within the greater context of adult urology. This involves, from an institutional standpoint, proportional distribution of equipment cost and operating room time. However, the pediatric urology team primarily determines goals for volume expansion, operative case selection, resident training and surgical innovation within the specialty...

The demonstration of field-effect transistors (FETs) based entirely on single-walled carbon nanotubes (SWNTs) would enable the fabrication of high-on-current, flexible, transparent and stretchable devices owing to the excellent electrical, optical, and mechanical properties of SWNTs. Fabricating all-SWNT-based FETs via simple solution process, at room temperature and without using lithography and vacuum process could further broaden the applicability of all-SWNT-FETs. In this work, we report on biologically assembled all SWNT-based transistors and demonstrate that ion-gel-gated network structures of unsorted SWNTs assembled using a biological template material enabled operation of SWNT-based transistors at a very low voltage...

Open anterior repair for inguinal hernia offers several distinct advantages over endoscopic repair, especially when real-world effectiveness is taken into account. The learning curve for endoscopic techniques is long, whereas the Lichtenstein and other open tension-free techniques are easier to teach and replicate at all levels. The outcomes of Lichtenstein repairs for primary inguinal hernia as performed by non-experts and supervised residents are comparable to those of experts. Moreover, open tension-free repair does not require expensive instruments or dedicated equipment, other than the prosthetic mesh...

Quaternary ammoniums are cations having widespread use in organic electrolytes for high performance electrochemical double layer capacitors (EDLCs) due to their various advantages such as high electrochemical stability and inexpensive production cost. However, the decomposition of quaternary ammoniums via Hofmann elimination hinders their applications for EDLCs operating at elevated temperatures. This study systematically investigates the reactivity of four different quaternary ammoniums (tetraethyl-, triethylmethyl-, diethyldimethyl-, and trimethylethyl-ammonium) in EDLC by utilizing density functional theory calculations and Brownian dynamics simulations complemented with molecular dynamics simulations...

BACKGROUND: One of the most common outcomes of lung resections are parenchymal air leaks. These air leaks are most often self-limited and spontaneously resolve several days after surgery. Historically, only prolonged air leaks have been considered to have a significant effect on patient outcomes. This study aims to evaluate the impact of any air leak complications (aALCs) on resource utilization and mortality. METHODS: The Premier Perspective(®) database was used to identify all elective primary lobectomy, segmentectomy, and wedge resections performed from 2012 to 2014; aALC was defined as a composite of air leak and pneumothorax...

The parotid duct can be damaged in traumatic injuries and surgical interventions. Early diagnosis and treatment of a duct injury is of great importance because complications such as sialocele and salivary gland fistula may develop if the duct is not surgically repaired. We think the cuff of an intubation tube is an ideal material in parotid duct repair, because of its technical characteristics, easiness of availability, and low-cost. In this paper, we described the use of the cuff cannula of an intubation tube for the diagnosis and treatment of parotid duct laceration, as a low-cost and easy to access material readily available in every operating room...

BACKGROUND: Studies of shared (patient-provider) decision making for elective surgical care have examined both the decision whether to have surgery and patients' understanding of treatment options. We consider shared decision making applied to case scheduling, since implementation would reduce labor costs. METHODS: Study questions were presented in sequence of waiting times, starting with 4 workdays. "Assume the consultant surgeon (ie, the surgeon in charge) you met in clinic did not have time available to do your surgery within the next 4 workdays, but his/her colleague would have had time to do your surgery within the next 4 workdays...

High-performance gas sensors based on metal oxides operated at room temperature are of great interest due to their energy saving and cost effective characteristics. How to improve the sensitivity of metal oxide gas sensors and enable their room-temperature operation are challenging for their realistic applications. In this work, we have designed and fabricated Al-doped NiO nanosheets for greatly enhanced NO2 detection at room temperature. Different amounts of Al were doped into two-dimensional (2D) NiO nanosheets via a fast and facile microwave assisted solvent-thermal technique...

BACKGROUND: Congenital nasolacrimal duct obstruction (NLDO) is a common condition causing excessive tearing in the first year of life. Infants present with excessive tearing or mucoid discharge from the eyes due to blockage of the nasolacrimal duct system, which can result in maceration of the skin of the eyelids and local infections, such as conjunctivitis, that may require antibiotics. The incidence of nasolacrimal duct obstruction in early childhood ranges from 5% to 20% and often resolves without surgery...

The mid-infrared (MIR) spectral range, pertaining to important applications, such as molecular "fingerprint" imaging, remote sensing, free space telecommunication, and optical radar, is of particular scientific interest and technological importance. However, state-of-the-art materials for MIR detection are limited by intrinsic noise and inconvenient fabrication processes, resulting in high-cost photodetectors requiring cryogenic operation. We report black arsenic phosphorus-based long-wavelength IR photodetectors, with room temperature operation up to 8...

PURPOSE OF REVIEW: Total joint arthroplasty is regarded as a highly successful procedure. Patient outcomes and implant longevity, however, are related to proper alignment and position of the prostehses. In an attempt to reduce outliers and improve accuracy and precision of component position, navigation and robotics have been introduced. These technologies, however, come at a price. The goals of this review are to evaluate these technologies in total joint arthroplasty and determine if they add value...

BACKGROUND: For patients undergoing spine surgery, the literature attributes significant increased perioperative risks/adverse events (AE) complications, longer length of stay (LOS), and higher 30-day readmission/reoperation rates to those with diabetes. Diabetics are often divided into those with insulin dependent diabetes (IDDM), and non-insulin dependent diabetes (NIDD). However, other series also compare those with uncontrolled diabetes (UCDM) vs. those with controlled DM (CDM). METHODS: We found a marked variation in the size and quality of studies identified in PubMed regarding the impact of diabetes on spinal surgery (e...

Outcome is the numerator for the value equation, with the denominator being cost; measurement of each is essential to determine the most effective care. With regard to both total shoulder arthroplasty and rotator cuff repair, outcomes of low (vs high) volume providers are associated with longer hospital stay, longer length of operating room time, increased hospital complications, and cost. This suggests that volume thresholds are a key to providing greater value. However, this effect can be modified through systematic efforts to measure outcome and thus improve...
