Assessing the attitude of surgical trainees towards virtual reality simulation: A national cross-sectional questionnaire study.

BACKGROUND: We performed a cross sectional study to determine the attitudes of surgical trainees and medical students towards virtual reality (VR) simulation in surgical training. A survey was devised through an iterative process before distribution to surgical trainees, foundation year doctors and medical students through online platforms. METHODS: The survey was disseminated within the United Kingdom through social media and email correspondence, in co-operation with national surgical organisations. 91 trainees responded from a variety of clinical specialities. RESULTS: VR technology in surgical training was viewed positively, with 91.3% of trainees agreeing that VR should be both an adjunct in surgical training as well as a competency-based assessment tool. Barriers to access were present, with access notably more challenging for senior surgeons. CONCLUSION: Virtual reality surgical simulation in surgical training is beginning to emerge as a genuine high-fidelity, low-risk solution to the lack of surgical case volume trainees are currently experiencing.

Understanding the role of Foundation doctors through a self-reported time-mapping pilot study.

INTRODUCTION: There is a reduction in Foundation trainee applications to speciality training and this is attributed to an administrative job role, with subsequent fears of burnout. This pilot study presents the findings of a real-time self-reporting tool to map a group of Foundation doctors' elective activities. Self-reporting is efficient, low cost to run and allows for repeated measures and scalability. It aimed to example how a time-map could be used by departments to address any work imbalances and improve both well-being and future workforce planning. METHOD: Foundation doctors', at a busy District General Hospital, were asked to contemporaneously report their work activities over an 'elective' day. Outcomes measures included the mean duration per task and the time of day these were performed. RESULTS: Nine Foundation doctors' returned 26 timesheet days. Foundation doctors' time was split between direct patient tasks (18.2%, 106.8 min per day), indirect patient tasks (72.9%, 428.6 min per day) and personal or non-patient activities. Indirect tasks were the most frequent reason for Foundation doctors leaving late. No clinical experience was recorded at all and only an average of 4% (23.4 min per day) of a Foundation doctors' time was spent in theatre. CONCLUSIONS: This particular cohort performed a high proportion of indirect tasks. These have been associated with burnout. Time-mapping is a low-cost, acceptable and seemingly scalable way to elucidate a clearer understanding of the type of activities Foundation doctors may perform. This methodology could be used to modernise the traditional Foundation doctor job description.

Defining Normal Parameters for the Male Nipple-Areola Complex: A Prospective Observational Study and Recommendations for Placement on the Chest Wall.

BACKGROUND: The nipple-areola complex (NAC) is important aesthetically and functionally for both sexes. Methods for positioning the NAC in males are less well established in the literature compared to females but are just as important. OBJECTIVES: This study aims to determine the normal parameters for the male NAC, to review literature, and to present a reliable method for preoperative placement. METHODS: Normal male patients, with no prior chest wall conditions, were prospectively recruited to participate. General demographics and chest wall dimensions were recorded-sternal notch to nipple (SNND), internipple (IND), anterior axillary folds distances (AFD), NAC, and chest circumference were measured. Comparisons were made using t test and ANOVA. RESULTS: One hundred and fifty-eight patients were recruited (age range, 18-90 years); mostly (86.7%) with normal or overweight BMI. The IND averaged 249.4 mm, the SNND averaged 204.2 mm, and the AFD averaged 383.8 mm. Areola diameter averaged 26.6 mm and for the nipple, 6.9 mm. The IND:AFD ratio was 0.65. There was no statistical difference in the IND:AFD ratio, SNND, or NAC parameters comparing different ethnic groups. The SNND increased with greater BMI (P ≤ 0.001). Using these data, we suggest ideal NAC dimensions and devised a simple method for positioning of the NAC on the male chest wall. CONCLUSIONS: This is the largest study, with the widest range in age and BMI, to date on this topic. Although fewer men than women undergo surgery to the breast, there is a growing awareness for enhancing the appearance of the male chest wall.

Treatment of Prominent Ears with an Implantable Clip System: A Pilot Study.

BACKGROUND: The earFold™ implantable clip system is a new treatment for prominent ears using an implant made from nickel-titanium alloy, forged into a predetermined shape. The implant is fixed to the cartilage then released, causing the cartilage to fold back. OBJECTIVES: The study aimed to test the safety and behaviour of the implant in vivo. METHODS: This was a Phase 1, prospective, nonrandomised study. Thirty-nine patients were recruited, from 7 to 57 years of age (22 adults and 17 children). Thirty-seven patients were followed up for a minimum of 18 months. A total of 131 implants was used to treat 75 ears. All treatments were performed under local anaesthetic. RESULTS: Eighteen patients asked for their implants to be left in place permanently. Twenty-one patients agreed to have their implants removed at 6, 12, or 18 months after insertion. Complications affected 8 patients and included extrusion, infection, hypertrophic scarring, and Spock-ear formation. No new complications have arisen in any of the patients since the conclusion of the study, up to a maximum of 47 months. Patients were overwhelmingly satisfied with the outcome of treatment. CONCLUSIONS: earFold can be used as a permanent implant to correct prominence of the human ear. It is best suited for treating prominent ears with a poorly formed or absent antihelical fold. The procedure is quick and predictable with a complication rate comparable to suture-based otoplasty techniques.

Laser therapy and photosensitive medication: a review of the evidence.

In the 2009 guidelines from the BMLA, the use of non-essential aesthetic lasers was contraindicated in patients receiving medication that causes whole-body photosensitisation as well as those causing local light sensitisation. Following this and anecdotal advice, many laser centres refuse to treat patients who are on known photosensitive medication. Therefore, specific patient cohorts that would benefit from laser therapy are being denied because of medications, such as long-term antibiotics for chronic facial acne. This article reviews the published literature on lasers and photosensitive medications, the mechanisms of photosensitivity and the role of laser in its production. The aim is to analyse the available evidence regarding adverse reactions to laser treatment related to photosensitive medication. A PubMed review of published article titles and abstracts was performed using the search term Laser with each of the following terms individually: photosensitive, photosensitiser, photosensitizer, phototoxicity, photoallergy, complications, case-report, tetracycline, minocycline, amiodarone, nitrofurantoin and medication. Four publications were identified, none of which reported any complication in the use of laser in patients taking photosensitising medication. As there are no published accounts of adverse effects of laser in patients with photosensitive medication, we performed a review of the mechanism of photosensitivity by compiling a list of photosensitive medication and the peak wavelength of radiation required to activate the drug. We recommend a national database of drugs and the wavelengths causing photosensitive reactions of each which a laser department can access prior to treatment.

Effect of human urine on the tensile strength of sutures used for hypospadias surgery.

INTRODUCTION: Hypospadias is the most common congenital condition affecting between 1 in 250 and 300 live births. Even in experienced hands, surgery to repair this congenital defect can have a high complication rate. Wound dehiscence is reported to occur in 5% and fistula formation in 6%-40% depending on technique. The choice of suture material has been shown to affect the complication rate although there is (currently) no consensus about the best suture material to use. Ideally, the sutures used for urethroplasty should be absorbable while maintaining sufficient mechanical strength to support the wounds until they are self-supporting and able to resist urinary flow. Previous studies have compared the effects of human urine on different suture materials especially catgut. However, catgut is now banned in Europe. Our study examined the tensile and breaking strength as well as rate of degradation for four types of absorbable suture now commonly used for hypospadias repairs in the UK. MATERIAL AND METHODS: We examined the effect of prolonged storage (up to 27 days) in human urine on 6/0 gauge Vicryl, Vicryl Rapide, Monocryl and polydioxanone (PDS) sutures. These four suture materials are commonly used by the senior plastic consultant surgeon (NK) for hypospadias repairs. 50 mm sections of these suture materials were stored in either urine or saline as control. At specified time points, each suture was placed in a uniaxial load testing machine to assess the stress-strain profile and the mechanical load required to break the suture was measured. KEY RESULTS: Exposure to urine reduced the tensile and breaking strength of all the suture materials tested. PDS demonstrated the greatest resilience. Vicryl Rapide was the weakest suture and degraded completely by day 6. Vicryl and Monocryl had similar degradation profiles, but Vicryl retained more of its tensile strength for longer. CONCLUSIONS: There is a balance to be struck between the duration that a suture material must remain in any surgical wound and the risk that it causes foreign body effects. The results of this study suggest that Vicryl has the best characteristics for urethroplasty of the four suture materials tested.

Iron deficiency and sleep disordered breathing in children--cause or effect?

OBJECTIVE: Iron deficiency is associated with paediatric sleep disturbances; in particular, restless leg syndrome (RLS) and periodic limb movement disorder (PLMD). Correction of iron deficiency has been shown to improve sleep disordered breathing (SDB) in certain adult populations. We evaluated the iron status of children diagnosed with SDB undergoing adenotonsillectomy. METHODS: Consecutive children undergoing adenotonsillectomy for SDB between January 2007 and January 2008 were analysed. Routine blood tests were performed including full blood count and iron studies. Children were grouped according to age; 0-2 years (group A), 2-6 years (group B) and above 6 years (group C). Results were compared to local normal values and published data regarding normal values for paediatric populations. RESULTS: 94 children were included (60 male, 34 female). Mean age was 3.9 years (range 1.2-13.4 years). Iron deficiency was most marked in group A (n=8), with levels of ferritin (12.4), Mean Cell Haemoglobin (MCH) (25.0), iron saturation (16%, normal 20-40%) all below normal and Hb at the bottom of the normal range (11.0, normal 11-14.5). In group B (n=76), ferritin (19.4) and MCH (26.5) were again below normal but were higher than for group A. Average Hb for group B was 11.9. CONCLUSION: The association between low iron and SDB in children has not previously been described. The results of this study highlighted low iron status in the children undergoing adenotonsillectomy for SDB. This was most severe in children under 6 years old. It is unclear whether low iron levels represent a cause or effect of SDB.
