F M Ryba, K George
Point-of-care ultrasound is an ultrasound examination that is made at the bedside by the examining clinician in the Accident and Emergency department, clinic, ward, or operating theatre, and it has been growing in popularity since it was first introduced in the 1990s. It is used as an adjunct to clinical examination to aid diagnosis or treatment. We have carried out a pilot survey to assess whether oral and maxillofacial surgeons in the United Kingdom either need or desire to make such an examination. We present the results of our survey and discuss the uses and benefits of point-of-care ultrasound in oral and maxillofacial surgery...

BACKGROUND: The prophylactic use of antimicrobial agents to prevent infections in non-surgical situations has hardly been investigated. We investigate the extent, indications and appropriateness of antimicrobial prophylaxis given outside the operating room in a tertiary care hospital. METHODS: Four point-prevalence surveys were conducted in which all inpatients on that day were screened for the use of prophylactic antimicrobials: medical prophylaxis, prophylaxis around non-surgical interventions and surgical prophylaxis given on the ward...

PURPOSE: Surgical cameras are prevalent in modern operating theatres often used as surrogates for direct vision. A surgical navigational system is a useful adjunct, but requires an accurate "hand-eye" calibration to determine the geometrical relationship between the surgical camera and tracking markers. METHODS: Using a tracked ball-tip stylus, we formulated hand-eye calibration as a Perspective-n-Point problem, which can be solved efficiently and accurately using as few as 15 measurements...

High aerobic glycolysis, as one of the hallmarks of cancer cells, requires nicotinamide adenine dinucleotide (NAD(+)) as a vital co-factor, to guarantee the flow of glycolysis. Malate dehydrogenase (MDH), as an important enzyme in cancer metabolism, is a source of NAD(+) additional to lactate dehydrogenase (LDH). The current study aimed to elucidate the kinetic parameters of MDH in human breast cancer and evaluate its supportive role in the glycolysis pathway. The Michaelis-Menten constant (Km) and maximum velocity (Vmax) of MDH were determined in the crude extracts of human breast tumors and healthy tissue samples, which were obtained directly from the operating theatre...

BACKGROUND: The use of dermal fillers in minimally invasive facial aesthetic procedures has become increasingly popular of late, yet as the indications and the number of procedures performed increase, the number of complications is also likely to increase. Paying special attention to specific patient characteristics and to the technique used can do much to avoid these complications. Indeed, a well-trained physician can also minimize the impact of such problems when they do occur. METHODS: A multidisciplinary group of experts in aesthetic treatments reviewed the main factors associated with the complications that arise when using dermal fillers...

PURPOSE: The use of active medical devices in clinical routine should be as safe and efficient as possible. Usability tests (UTs) help improve these aspects of medical devices during their development, but UTs can be of use for hospitals even after a product has been launched. The present pilot study examines the costs and possible benefits of UT for hospitals before buying new medical devices for theatre. METHODS: Two active medical devices with different complexity were tested in a standardized UT and a cost-benefit analysis was carried out assuming a different device bought at the same price with a higher usability could increase the efficiency of task solving and due to that save valuable theatre time...

PURPOSE: Improved surgical outcome and patient safety in the operating theatre are constant challenges. We hypothesise that a framework that collects and utilises information -especially perceptually enabled ones-from multiple sources, could help to meet the above goals. This paper presents some core functionalities of a wider low-cost framework under development that allows perceptually enabled interaction within the surgical environment. METHODS: The synergy of wearable eye-tracking and advanced computer vision methodologies, such as SLAM, is exploited...

Sir Victor Alexander Haden Horsley (1857-1916), the pioneering British neurological surgeon, passed away 100 years ago. He died young in his sixtieth year from the effects of heat stroke while serving as consulting military surgeon to the Mediterranean Expeditionary Force in Amarah, modern-day Iraq, and was buried in the now largely abandoned "Amara War Cemetery." By the time of his death in 1916, Victor Horsley had established himself as one of the most eminent innovators of modern neurological surgery. His pioneering researches in cerebral physiology earned him an early reputation in the field, and his experiences with vivisection allowed him to confidently operate on the brain and spinal cord at a time when surgical intervention of the nervous system was fraught with uncertainty...

AIM: Children who are admitted with acute orthopaedic problems are often fit and healthy. The house officer (ie, intern) is required to carry out the formal clerking/admission of inpatients. However, they are often also busy with sick ward patients, which leads to delays in formal clerking of these children until after they have been to the operating theatre (OT). The aim of this study was to assess what information, if any, is missed in children who were seen by a house officer prior to going to OT, compared to those who were not...

A doctor's attire is vital for both a positive first impression and the overall healthcare experience of patients. We attempted to understand patients' and doctors' perceptions and preferences regarding six types of dress codes used by doctors in different situations and locations. A total of 87 patients and 46 doctors participated in the study. Separate sets of questionnaires, that included four demographic questions and 14 survey questions, were given to the patient and doctor groups. Most patients preferred doctors dressed formally in white coats irrespective of scenarios or locations whereas majority of doctors preferred formal attire without white coats...
