Comparison of long-term outcomes of breast conservation and reconstruction after mastectomy using BREAST-Q.

AIMS: Patients' post-operative wellbeing determines the impact and effectiveness of breast reshaping and reconstruction procedures. The aim of the study was to evaluate and compare four different types of breast reconstruction: bilateral therapeutic mammaplasty, DIEP flap, ELD with immediate lipomodelling and implant-based reconstruction using BREAST-Q. METHODS: Patients who underwent breast reconstruction by one of the above-mentioned methods were identified from a retrospective register and sent BREAST-Q questionnaires. Univariate and multivariate analysis of BREAST-Q scores and clinical characteristics were performed for identifying trends between and within groups. RESULTS: A total of 240 patients were identified with a response rate of 57%. Patients receiving implants were statistically less satisfied with breast reconstruction (mean 57%) and tended to be younger with lower BMI in comparison to other groups. There were no statistical differences in psychosocial wellbeing or patient experience between groups. Despite the fact that clinically these groups were heterogeneous, satisfaction with breast was similar in the remaining three autologous groups (range 70-75%). Detailed analysis and interpretation of quality-of-life scores, clinical differences and trends identified in the multivariate analysis along with nuances between surgical techniques used in our unit for breast reshaping and reconstruction, have been performed. CONCLUSIONS: The most important goal of breast reconstruction is to restore patients' quality of life and satisfaction with breast. Identifying factors which can potentially predict poor outcomes will improve the informed consent process and patient selection.

Bilateral persistent sciatic arteries complicated by unilateral acute lower limb ischaemia.

We present a case of a middle-aged Caucasian woman who developed acuteon top of chronic limb ischaemia secondary to thrombotic occlusion of a persistent sciatic artery (PSA). Timely investigation and treatment were instituted resulting in a favourable outcome. PSA is an uncommon congenital, developmental, arterial anomaly which can cause serious lower limb complications such as acute or critical limb ischaemia and amputation. As this condition is rarely encountered in regular clinical practice, and has a limb-threatening potential, it is important to be aware of its cause, presentation and management. We describe the embryologic aetiology of PSA and discuss different investigation modalities and treatment options.

Homozygous Factor V Leiden Thrombophilia in a Patient With Histologically Confirmed Thromboangiitis Obliterans.

Thromboangiitis obliterans (TAO) is a vasculitis characterised by segmental occlusions of small to medium-sized arteries and superficial veins, and a curious predilection for young male smokers. The exact aetiology remains unknown. Current theories postulate it is an autoimmune endarteritis, triggered by some constituent of tobacco and occurring in genetically susceptible individuals. The disease can pose a diagnostic challenge, requiring a high degree of clinical suspicion, particularly in male smokers aged between 20-45 presenting with peripheral ischaemia. The fundamental principle of management is absolute tobacco abstinence. In this article, we report the case of a 27-year-old man who presented with infected, chronic wounds of his upper and lower extremities. He was initially treated with antibiotics and surgical debridement. Unfortunately he went on to develop a protracted course of complications due to poor wound healing ultimately leading to amputation of several digits. A diagnosis of TAO was suspected, and this was later confirmed histologically. Incidentally and of note, the patient was also found to be homozygous for factor V Leiden. An association between TAO and hypercoagulable states, specifically heterozygous factor V Leiden mutation, has been previously described. It is unclear if a synergistic effect between TAO and homozygosity for factor V Leiden may have contributed to the severity and unremitting nature of our patient's symptoms. We present this case in order to highlight the importance of early recognition of the condition and the need to offer comprehensive smoking cessation support in order to prevent amputation and other complications of poor wound healing.

Impact of advanced endoscopic imaging on Barrett's esophagus in daily clinical practice.

BACKGROUND AND AIMS: Several advanced imaging techniques have been proposed to improve the visualization of dysplastic regions within Barrett's epithelium, with some evidence for the use of narrow-band imaging (NBI) and acetic acid chromoendoscopy (AAC). METHODS: We retrospectively analyzed consecutive cases of Barrett's esophagus, diagnosed using white-light endoscopy and confirmed histologically by the presence of intestinal metaplasia, between April 2007 and April 2010 in a large community hospital. A change in practice was then instituted, whereby a Barrett's team consisting of specialist endoscopists was formed in an attempt to standardize and improve the quality of surveillance. Barrett's epithelium was inspected with both white-light imaging and NBI in all patients. Where the length of Barrett's epithelium was 3 cm or more, AAC was also used. One and a half percent acetic acid was sprayed onto the Barrett's segment and loss of aceto-whitening observed after a 2-minute period. Any abnormal areas noted during advanced imaging underwent target biopsy sampling. We subsequently compared the dysplasia detection rate in Barrett's epithelium identified between April 2011 and April 2014 after these changes. Observed differences between the cohorts were analyzed with the Fisher exact test and the Student t test. RESULTS: From 2007 to 2010 Barrett's esophagus was identified during 560 gastroscopies in 392 individual patients. The mean maximal Barrett's esophagus recorded length was 4.4 cm (range, 1-10), with an average of 4.7 esophageal biopsy specimens taken per endoscopy. In comparison, from 2011 to 2014 Barrett's esophagus was identified during 856 endoscopies in 630 patients. From 2011 to 2014 the Barrett's team performed 85% of all procedures using the aforementioned techniques. The mean maximal Barrett's esophagus length was 3.8 cm (range, 1-16), with an increased average of 5.8 biopsy specimens per endoscopy taken (P < .01). Both cohorts were comparable in age and gender distribution. Our data demonstrated no significant difference in the relative frequencies of occurrence of dysplasia detected between both cohorts of patients. From 2007 to 2010 dysplasia was detected in 11.0% (n = 43) of patients. This consisted of low-grade dysplasia in 7.7% of patients and high-grade dysplasia or cancer 3.3%. From 2011 to 2014 this compared with dysplasia in 11.3% (n = 71) of patients, with low-grade dysplasia in 9.4% and high-grade dysplasia or cancer in 1.9%. CONCLUSIONS: Our data show that the use of NBI and AAC in the imaging of Barrett's esophagus did not result in an increased detection rate of dysplasia in routine clinical practice. These findings concur with the recommendations of existing Barrett's esophagus surveillance guidelines, which advocate the continued use of quadratic biopsy sampling within general surveillance programs.

Dog bites and diabetic peripheral neuropathy: a dangerous combination.

All animal bites have the potential to cause significant infection. In the UK, dogs are the most common source of bites. Incidence of hospital attendances attributable to dog bites has risen over the last decade. Patient groups at particular risk of bites and/or complications of infection include those at extremes of age, immunosuppressed and patients with diabetes. We report the case of a patient with diabetic peripheral neuropathy, who was admitted on two separate occasions with unprovoked bites to his toes whilst asleep, by his pet dog. He ultimately required terminalisation of the affected digits. Although unusual, this mechanism of injury has been previously described in literature. However, we are unaware of cases reporting multiple separate incidences involving the same patient and animal. We present this case to highlight the perils of untrained pet ownership in diabetic patients with peripheral neuropathy and the importance of prompt medical and surgical treatment of injuries.

A not-so-sweet diagnosis - leukocytoclastic vasculitis masquerading as squamous cell carcinoma.

Leukocytoclastic vasculitis (LCV) is a rare small-vessel vasculitis characterised by neutrophilic inflammation of post-capillary venules. Incidence varies from 3 to 4.5 per 100 000 people per year. Patients typically present with painful, itchy purpura and erythema, although clinical manifestations can vary making diagnosis a challenge. We report the case of a 75-year-old man with a history of a previously completely excised and grafted squamous cell carcinoma (SCC) on the dorsum of his hand, who presented with an acutely swollen, erythematous and ulcerated lesion adjacent to the graft site. A shave biopsy failed to definitively exclude SCC recurrence. He was referred to the Plastics team who initially suspected Sweet's syndrome but could not rule out SCC recurrence. The patient underwent formal mapping incisional biopsies that later diagnosed LCV. He was managed conservatively and made an excellent recovery. We present clinical photographs and histology to illustrate disease progression. LCV is typically self-limiting with a good overall prognosis, but a minority of patients follow a protracted course, which may require treatment in the form of systemic corticosteroids or colchicine. LCV can only be confirmed histologically. We present this case in order to highlight the importance of adequate tissue biopsy when there is diagnostic uncertainty with an acute dermatosis, particularly in the context of previous skin malignancy.
