ABSTRACT
Patients receiving hemodialysis have an increased risk of developing nonmelanoma skin cancers, such as cutaneous squamous cell carcinoma (SCC). Management of SCC usually relies on complete surgical excision of the primary tumor and may require regional lymph node dissection due to lymphatic spread. An 81-year-old man with an arteriovenous fistula (AVF) presented with an unusually aggressive metastatic well-differentiated SCC, necessitating an axillary dissection for lymph node metastasis. He had been referred for radiotherapy to complete his oncological treatment following excision of the primary SCC on his forearm. An AVF site is subjected to significant changes in circulatory pressure, leading to reduced lymphatic drainage and likely focal immunosuppression. Increased lymphatic burden, combined with repeated trauma to the fistula in an immunosuppressed patient, potentially precipitated the development of an SCC on the affected limb. The individual risk factors for SCC such as sites of chronic inflammation and repeated trauma, host immunosuppression, and renal disease are well established. This patient demonstrates the perfect storm of all these risk factors, leading to a highly malignant metastatic SCC. As the standards of renal care improve and the number of patients with AVF increases, we must remain vigilant in the management of SCCs in these patients.
ABSTRACT
INTRODUCTION: From 85348 inmates in England and Wales, over 26,000 incidents of assault and 40,000 of self-harm were reported from within prisons in 2016. This study focuses primarily on burn injuries in prison, determining the predominant aetiology as well as clinical outcomes of these injuries. METHODS: Data was retrieved retrospectively and a case series performed, including all burns referred from regional prisons to our centre from 2007 to 2017 and comprising patient demographics, mechanism of injury, total body surface area affected, management, and outcome. Cost analysis of care was conducted using a previously published framework. RESULTS: 18 cases from three regional prisons were recorded, with 67% from a single prison. Referrals rose exponentially over time, with 44% occurring in 2017. 94% were scald burns, and 56% secondary to assault, primarily through the use of kettles and mostly targeting the face and trunk. The mean TBSA of burn was 2.89% (<1-8%), and 80% received first aid. 72.2% were admitted to hospital for an average of 4 days. All burns were managed nonoperatively with dressings and underwent on average 2 outpatient reviews (1-8). DISCUSSION: The disproportionate spread of referrals across the prisons correlates partly with the respective populations, but may also represent contrasting medical provisions. The recurring method of assault reflects the relative ease of access to hot water as a harmful agent, predominantly presenting with scalds affecting more critical areas, and with concurrent physical trauma in nearly half of cases which presents management challenges. CONCLUSION: Targeted education is recommended to reduce the incidence and ensure adequate management of burns in prison, referrals for which are demonstrably rising. Accordingly, the Burns Outreach team can provide training to in-house prison health staff and review referrals to specialist Burns services, aiming to ensure equitable care while alleviating costs associated with transfer to and management in hospital.
