Recurrent oral ulceration caused by HSV-1 may be seen by the general dental practitioner and can cause significant morbidity.

Objective: Accurate diagnosis of parotid neoplasia is a key to determine the most appropriate patient management choice, including the need for surgery. This review provides an update of the literature on current practice and outcomes of parotid tissue sampling techniques, with an emphasis on ultrasound-guided core biopsy (USCB) and comparison with fine needle aspiration cytology (FNAC). Methods: A literature review of EMBASE, Medline, PubMed and Google Scholar was conducted. Results: USCB has higher sensitivity, specificity and lower non-diagnostic rates than optimized FNAC. It also has a significantly higher sensitivity for the detection of malignancy. Significant complications post-USCB are uncommon, with only one reported case of tumour seeding and no cases of permanent facial nerve dysfunction. The technique is less operator-dependent than FNAC, with less reported variation in results between institutions. Conclusions: USCB can be considered as the optimum tool of choice for the diagnosis of parotid neoplasia. This would particularly be the case in centres utilizing FNAC with high non-diagnostic rates or reduced diagnostic accuracy when compared to USCB published data, or in centres establishing a new service. Advances in knowledge: An update of the role and outcomes of USCB in the diagnosis of parotid gland pathologies. Research shows that USCB preforms better than FNAC, in terms of sensitivity and specificity, particularly in the case of malignant neoplasia. Complications following USCB were found to be higher than that of FNAC; however, no long-term major complications following either method have been reported in the literature.

Summary A virtual clinic was developed from an existing telemedicine system to manage hand trauma in the Queen Victoria Hospital, East Grinstead, UK, during the first wave of the COVID-19 pandemic. This study evaluates the accuracy of the assessments made and makes comparisons to the traditional face-to-face clinic. The accuracy of assessment was analysed by comparing diagnosis with findings at surgery. One hundred and eighty-nine virtual assessments conducted by telephone with photographic data or by video were compared to 129 face-to-face assessments conducted prior to the pandemic. There was no difference in the accuracy of virtual and face-to-face clinics for patients treated surgically (p=0.27); treatment was correctly predicted for 87% of the virtual group and 78% of the face-to-face group. However, fewer virtual assessments led to a surgical outcome (p=0.0064); 68% of the virtual group had surgical outcomes compared to 82% of the face-to-face group. Most face-to-face assessments were done by a specialty trainee compared to a range of clinicians in the virtual clinic. Accuracy of assessment among trainees was significantly associated with experience for the virtual (p=0.045) but not face-to-face clinics (p=0.94). Virtual assessment by video versus telephone plus photographs were similarly accurate. We conclude that virtual triage serves as a successful alternative to face-to-face appointments. It is robust and succeeds in reducing footfall to the hospital site in line with recent social distancing measures against COVID-19. We have shown that video conferencing triage is no better than telemedicine triage with telephone and photographs.

A 25-year-old man presented to a major trauma centre with multiple stab wounds, most significantly to the right buttock. Triple-phase CT revealed no acute bleeding and his wounds were closed. In the month following injury, he re-presented seven times to the emergency department (ED) complaining of bleeding and wound breakdown. After his seventh ED attendance, he was examined under general anaesthesia. Intraoperatively, profuse arterial bleeding was encountered and the local major haemorrhage protocol was activated. The on-call consultant vascular surgeon attended and definitive control was achieved. A large haematoma had acted to tamponade ongoing arterial bleeding and an underlying pseudoaneurysm: a finding not reported, but present, on the initial CT angiogram. Following 24 hours in the intensive care unit, he was transferred to the surgical ward and discharged 4 days later. Regular review in the outpatient department over the following 9 weeks monitored successful wound healing.
