Barista's fracture: a new occupational hazard.

Stress fracture of the clavicle is a rare injury usually occurring in high-level athletes. It is typically a result of repetitive sporting activity or unusual strain. We present the first case of an occupational clavicle stress fracture in a young female barista. The patient initially presented with insidious onset clavicular pain. There was no history of trauma, and an undisplaced fracture was present on the plain radiograph but overlooked by the emergency physicians. Two weeks later, the patient presented again with worsening symptoms, and a displaced fracture of the clavicle was diagnosed on plain radiograph. A thorough occupational history revealed the cause of her pain, which was the mechanical activity of coffee tamping and the fracture went on to unite with no further complications. No other cause was found on investigations including magnetic resonance imaging. The fracture healed with cessation of coffee tamping. This case highlights a previously unrecognised occupational hazard of coffee tamping as a potential cause of stress fracture of clavicle.

Cold burn injuries in the UK: the 11-year experience of a tertiary burns centre.

BACKGROUND: Guidance for the management of thermal injuries has evolved with improved understanding of burn pathophysiology. Guidance for the management of cold burn injuries is not widely available. The management of these burns differs from the standard management of thermal injuries. This study aimed to review the etiology and management of all cold burns presenting to a large regional burn centre in the UK and to provide a simplified management pathway for cold burns. METHODS: An 11-year retrospective  analysis (1 January 2003-31 December 2014)  of all cold injuries presenting to a regional burns centre in the UK was conducted. Patient case notes were reviewed for injury mechanism, first aid administered, treatment outcomes and time to healing. An anonymized nationwide survey on aspects of management of cold burns was disseminated between 13 July 2015-5 October 2015 to British Association of Plastic Reconstructive and Aesthetic Surgeons (BAPRAS) and Plastic Surgery Trainees Association (PLASTA) members in the UK. Electronic searches of MEDLINE, EMBASE and the Cochrane Library were performed to identify relevant literature to provide evidence for a management pathway for cold burn injuries. RESULTS: Twenty-three patients were identified. Age range was 8 months-69 years. Total body surface area (TBSA) burn ranged from 0.25 to 5 %. Twenty cases involved peripheral limbs. Seventeen (73.9 %)cases were accidental, with the remaining six (26.1 %) cases being deliberate self-inflicted injuries. Only eight patients received first aid. All except one patient were managed conservatively. One case required skin graft application due to delayed healing. We received 52 responses from a total of 200 questionaires. Ninety percent of responders think clearer guidelines should exist. We present a simplified management pathway based on evidence identified in our literature search. CONCLUSIONS: Cold burns are uncommon in comparison to other types of burn injuries. In the UK, a disproportionate number of cold burn injuries are deliberately self-inflicted, especially in the younger patient population. Our findings reflect a gap in clinical knowledge and experience. We proposed a simplified management pathway for managing cold burn injuries, consisting of adequate first aid using warm water, oral prostaglandin inhibitors, deroofing of blisters and topical antithromboxane therapy.

Assessment of Emergency Department Eye Examinations in Patients Presenting with Mid-Face Injury.

BACKGROUND: One-fifth of patients with severe facial trauma suffer ophthalmic injury. Currently, patients presenting with mid-face injury to the emergency department (ED) undergo visual examination and then further assessment by ophthalmologists and with computed tomography (CT) scanning. The utility of the initial visual examination in the ED, performed by nonophthalmologists, remains unclear. OBJECTIVE: We aimed to objectively identify whether a more thorough initial visual assessment, performed by nonophthalmologists in the ED, was associated with improved ophthalmic outcomes. METHODS: Patients (n = 100) were retrospectively recruited from a tertiary craniomaxillofacial center. Visual examinations performed in the ED were scored objectively and measured against defined management and prognostic outcomes. RESULTS: There was no significant difference between more thorough initial visual examination and reduced time to ophthalmology assessment or reduced visual complications. There was no correlation between more comprehensive examination and incidence of CT scanning. CONCLUSIONS: We identified no significant difference between a comprehensive visual examination performed by nonophthalmologists in the ED, and improved ophthalmic outcomes. Physicians assessing patients with mid-face trauma in the ED should rule out eye emergencies, including retrobulbar hemorrhage and penetrating globe injury, and initiate expeditious CT scan and assessment by specialist ophthalmologists.

Bioengineering for Organ Transplantation: Progress and Challenges.

Organ transplantation can offer a curative option for patients with end stage organ failure. Unfortunately the treatment is severely limited by the availability of donor organs. Organ bioengineering could provide a solution to the worldwide critical organ shortage. The majority of protocols to date have employed the use of decellularization-recellularization technology of naturally occurring tissues and organs with promising results in heart, lung, liver, pancreas, intestine and kidney engineering. Successful decellularization has provided researchers with suitable scaffolds to attempt cell reseeding. Future work will need to focus on the optimization of organ specific recellularization techniques before organ bioengineering can become clinically translatable. This review will examine the current progress in organ bioengineering and highlight future challenges in the field.

Medial radial head dislocation associated with a proximal olecranon fracture: a bado type v?

The Monteggia fracture is relatively rare. We present an unreported configuration of a traumatic olecranon fracture with a concomitant medial radial head dislocation in a 3-year-old male. This injury was initially missed and required a subsequent operative intervention. Following surgery, there was evident fracture union, articular congruency, and a full functional recovery. Medial radial head dislocation is not accounted for in the Bado (1967) classification of the Monteggia lesion and hence we propose the addition of a Bado V category.

Idiopathic chondrolysis of the hip: presentation, natural history and treatment options.

Idiopathic chondrolysis of the hip is a rare disorder characterized by pain, stiffness, limp and radiological loss of joint space of the affected hip. The clinical outcome varies from complete recovery to fibrous ankylosis. Management remains controversial. We aim to outline the natural history and pathology of the disease and treatment strategies.

Experience of ReCell in Skin Cancer Reconstruction.

The ReCell system (Avita Medical) is a cell culture product that allows the immediate processing of a small split-thickness skin biopsy to produce a complete population of cells including keratinocytes, melanocytes, Langerhans cells and fibroblasts. This series is the first to highlight the reconstructive applications of ReCell following ablative skin cancer surgery. The ReCell system was utilized for three patients following skin cancer excision. In two cases, the cells were applied to forehead flap donor sites following nasal reconstruction. In one case, the cells were applied to the calvarial periosteum following wide local excision of a melanoma scar. Assessment of the treated area was performed using the patient and observer scar assessment scale after 1 year. The Patient and Observer Scar Assessment Scale (POSAS) scores for the 2 patients treated with ReCell following forehead flap surgery were 22 and 32. The score for the patient that underwent wide local excision of a melanoma scar was 45. The absence of a donor site, accelerated healing and the satisfactory aesthetic appearance of the mature scars in this series suggest that ReCell may play a useful role in reconstruction following skin cancer excision.

Transfusion drains versus suction drains in total knee replacement: meta-analysis.

PURPOSE: The use of autologous blood transfusion drains in orthopaedic surgery has been the subject of debate for several years. The aim of this meta-analysis was to review the use of autologous blood transfusion drains in total knee replacement. METHODS: The primary outcomes were as follows: the number of patients requiring homologous blood transfusion, pre-operative haemoglobin and post-operative haemoglobin days 5-7. The secondary outcome measures for the meta-analysis were drainage volume, length of hospital stay, average number of units transfused per patient, post-operative wound infection, and deep vein thrombosis. RESULTS: Eight randomised controlled trials met the inclusion criteria and were included in this analysis. Autologous transfusion drains were associated with a decrease in the number of patients requiring post-operative blood transfusion (pooled odds ratio = 0.36, 95% CI = 0.15-0.85, P = 0.02), the number of units transfused per patient (weighted mean difference = -0.84 (95% CI = -1.13 to -0.56), P < 0.0001), and length of hospital stay (weighted mean difference = -0.25 (95% CI = -0.48 to -0.01), P = 0.04). CONCLUSION: The results of our study highlight both likely clinical and economic benefits within total knee replacement surgery. The clinical benefits of autologous transfusion drains in the total knee replacement surgery suggested by this meta-analysis include a reduced requirement for post-operative blood transfusion and a shorter length of hospital stay. However, further large-scale high-powered randomized controlled trials are recommended to further elucidate subtle effects of autologous drains on post-operative outcome following total knee replacement.
