The maser-the microwave progenitor of the optical laser-has been confined to relative obscurity owing to its reliance on cryogenic refrigeration and high-vacuum systems. Despite this, it has found application in deep-space communications and radio astronomy owing to its unparalleled performance as a low-noise amplifier and oscillator. The recent demonstration of a room-temperature solid-state maser that utilizes polarized electron populations within the triplet states of photo-excited pentacene molecules in a p-terphenyl host paves the way for a new class of maser...

We describe a case of a 28-month-old boy who presented to our emergency department with a right orbital penetration by an iron nail. At presentation, no pain or functional loss were noted. Plain head radiographs and computed tomography were performed and demonstrated a two centimeters long nail penetrating the right orbit. The foreign body was extracted carefully in the operating room. No complications were observed upon follow-up. Rarely, orbital penetration by an iron-nail can present without functional disturbances or pain and is not necessarily accompanied by sequelae...

Anatomy knowledge is not only essential for surgeons but also has importance for anyone who performs an invasive procedure on a patient, and provides examination and diagnosis of patients and sharing of these findings to the patient and other medical professionals. It is accepted that most surgical procedures could facilitate anatomic perception in surgical internships. There is an educational tendency to explore innovative instructional tools and methods that can help support current education styles. This study investigates the effect of a green laser pointer on students' perceptions and educational effectiveness when neck dissection is performed in the operating room...

RATIONALE: Myoclonic movement is a rare side effect after general anesthesia. Since we use various intravenous agents during general anesthesia recently, it is troublesome to find out the exact cause of this neurologic complication. PATIENT CONCERNS: A 31-year-old female patient without any past medical history underwent hip arthroscopic surgery under general anesthesia. DIAGNOSES: Although there was no specific event during the operation, she showed a sudden myoclonic movement confined to left upper extremity in recovery room...

Introduction: Procedural sedation and analgesia (PSA) is used by non-anesthesiologists (NAs) outside of the operating room for several types of procedures. Adverse events during pediatric PSA that pose the most risk to patient safety involve airway compromise. Higher Mallampati scores may indirectly indicate children at risk for airway compromise. Medical governing bodies have proposed guidelines for PSA performed by NAs, but these recommendations rarely suggest using Mallampati scores in pre-PSA evaluations...

Myocardial protection during cardiac surgery is a multifaceted process that is structured to limit injury and preserve function. Evolving techniques use solutions with varying constituents that enter the systemic circulation and alter intrinsic systemic concentrations. This study compared two distinct cardioplegia solutions on affecting intraoperative glucose levels. Data were abstracted from a multi-institutional perfusion registry, including a total of 1,188 propensity-matched cases performed from January through October 2016, at 17 cardiac surgical centers across the United States in which both del Nido and 4:1 cardioplegia were used during the study period...

PURPOSE: Treatment patterns of carpal tunnel surgery by members of the American Society of Surgery of the Hand (ASSH) have recently been published. The majority of cases in this study were performed in the general operating room with intravenous (IV) sedation or a Bier block. Patients were most commonly prescribed hydrocodone for postoperative pain. The majority of carpal tunnel releases at our center are performed under local anesthesia alone, with plain acetaminophen (Tylenol) or codeine prescribed for postoperative pain...

OBJECTIVES: Simulation in resident medical education has traditionally focused on isolated components of a surgical procedure. We hypothesized that incorporating an interdisciplinary team into a high-fidelity simulation laboratory would enhance the modeling of real-world challenges during cardiac surgery. METHODS: Simulation exercises were performed with staffing by surgeons, anesthesiologists, perfusionists, surgical assistants, and operating room technicians. Twelve accredited cardiothoracic surgical residents were divided into 3 teams...

BACKGROUND: Periprosthetic joint infection is a major complication of total joint replacement surgery and is associated with significant morbidity, mortality and financial burden. Surgical body suits (space suits), originally designed to reduce the incidence of infection, have paradoxically recently been implicated in increased periprosthetic joint infection rates. Air exhausted from space suits may be a contributing factor to this increased rate of periprosthetic joint infection. AIM: Investigate the flow of air exhausted from space suits commonly used in modern operating theatres...

Full extent of gender differences on postoperative outcomes has never been studied on large scale, specifically postoperative complications. This study aims to assess the effect of gender on 30-day morbidity and mortality after major surgery. A retrospective cohort study was carried out using data of patients undergoing major surgeries from the American College of Surgeons' National Surgical Quality Improvement Program database between 2008 and 2011. Demographics, pre- and perioperative risk factors, as well as 30-day morbidities, both overall and specific, were reviewed...

The detection and concentration measurements of low concentrations of nitrogen dioxide (NO₂) are important because of its negative effects on human health and its application in many fields of industry and safety systems. In our approach, conducting graft copolymers based on the poly(3-hexylthiophene) (P3HT) conducting polymer and other side-chains, polyethylene glycol (PEG) and dodec-1-en, grafted on a poly(methylhydrosiloxane) backbone, were investigated. The grafts containing PEG (PEGSil) and dodec-1-en (DodecSil) in two variants, namely, fractions with shorter (hexane fraction -H) and longer (chloroform fraction -CH) side-chains of P3HT, were tested as receptor structures in NO₂ gas sensors...

A positive shift in the Dirac point in graphene field-effect transistors was observed with Hall-effect measurements coupled with Kelvin-probe measurements at room temperature. This shift can be explained by the asymmetrical behavior of the contact resistance by virtue of the electron injection barrier at the source contact. As an outcome, an intrinsic resistance is given to allow a retrieval of an intrinsic carrier mobility found to be decreased with increasing gate bias, suggesting the dominance of short-range scattering in a single-layer graphene field-effect transistor...

To compare perioperative outcomes in the three most common partial nephrectomy modalities: robotic (RPN), laparoscopic (LPN), and open (OPN), matched for nephrometry scores. Patients aged 16-85 who underwent RPN, LPN, or OPN from 2007 to 2014 for localized renal carcinoma within our healthcare system were enrolled. Age, sex, body mass index, and Charlson Comorbidity Index (CCI) as well as perioperative outcomes of estimated blood loss (EBL), length of hospital stay (LOS), ischemia time (IT), change in eGFR, positive margin rate, operative time (OT), and emergency room visit rates were compared between RPN, LPN, and OPN using the R...

The reported incidence of intraoperative retained instruments, such as needles, hangs around 0.06-0.11%. Leaving a needle inside the abdominal cavity can have significant medical and legal consequences. In addition, the retrieval can be hampered due to the limited visualization of the scope during minimally invasive surgery. Factors associated with an increased probability for NL have been described. Prevention for this situation includes: having one needle at a time inside the cavity, effective communication between all personnel in the operating room, evaluation of the strength of the suture-needle connection, avoid parking of needles intraoperatively, and a proper needle withdrawal...

Head and neck cancers become a severe threat to human's health nowadays and represent the sixth most common cancer worldwide. Surgery remains the first-line choice for head and neck cancer patients. Limited resectable tissue mass and complicated anatomy structures in the head and neck region put the surgeons in a dilemma between the extensive resection and a better quality of life for the patients. Early diagnosis and treatment of the pre-malignancies, as well as real-time in vivo detection of surgical margins during en bloc resection, could be leveraged to minimize the resection of normal tissues...
