Cutaneous Crohn disease presenting as "knife-edged" ulcers: a case report.

BACKGROUND: CCD presents as non-caseating granulomas within the skin at a site distant from the GI tract. CCD is a debilitating extraintestinal sequela of CD that can sometimes precede its GI manifestations. In the absence of GI symptoms, the histopathologic and clinical features of CCD can present as a variety of inflammatory skin conditions that can range from ruptured follicle-associated granulomas to cutaneous ulcerations. While a variety of therapeutic options for patients with CCD and concurrent luminal CD have been described in the literature, there is no standard treatment algorithm for the management of refractory CCD with limited or covert GI involvement. CASE REPORT: The authors discuss the case of a 33-year-old female who presented to the wound care clinic with multiple "knife-edged" cutaneous ulcerations involving the intertriginous spaces, found to be consistent with CCD. Her original cutaneous symptoms and diagnosis manifested with minimal GI involvement and responded to IVIG treatment. CONCLUSIONS: This case supports the inclusion of CCD in the differential diagnosis in patients with knife-edged granulomatous skin lesions in intertriginous locations. This clinical condition may present in the setting of no or limited GI symptoms. The management of CCD and a proposed treatment algorithm are also presented.

Compression therapy in peripheral artery disease: a literature review.

OBJECTIVE: Our objective is to examine the pathophysiology of oedema in the ischaemic and post-revascularised limb, compare compression stockings to pneumatic compression devices, and summarise compression regimens in patients with severe peripheral artery disease (PAD) without revascularisation, after revascularisation, and in mixed arterial and venous disease. METHOD: A scoping literature review of the aforementioned topics was carried out using PubMed. RESULTS: Compression therapy has been shown to increase blood flow and aid in wound healing through a variety of mechanisms. Several studies suggest that intermittent pneumatic compression (IPC) devices can be used to treat critical limb ischaemia in patients without surgical options. Additionally, compression stockings may have a role in preventing oedema after peripheral artery bypass surgery, thereby diminishing pain and reducing the risk of surgical wound dehiscence. CONCLUSION: Oedema may occur in the ischaemic limb after revascularisation surgery, as well as in combination with venous disease. Clinicians should not fear using compression therapy in PAD.

Atypical ulcers: a stepwise approach for clinicians.

Chronic ulcers are associated with significant morbidity and mortality. Typical ulcers are due to venous insufficiency, diabetes, ischemia, pressure, and lymphedema. A chronic ulcer that does not respond to standard therapies should be reevaluated for potential atypical etiologies. Atypical ulcers are less common and more difficult to diagnose due to a wide range of possible etiologies, including inflammatory (autoimmune), neoplastic, vasculopathy, hematologic, infectious, drug-induced, or external. No standardized approach to the management of complex atypical ulcers exists. In this review, a stepwise approach to atypical ulcers is proposed with the aim of assisting physicians in their identification and diagnosis. If perfusion is adequate and there are no signs of infection, then the authors recommend obtaining an ulcer biopsy for microbiologic, DIF, and histopathologic evaluation as the criterion standard for diagnosis. Laboratory testing, including an autoimmune panel, a hypercoagulable panel, and an infectious diseases panel, can further aid in diagnosis. Atypical ulcers often require multidisciplinary care, with input from specialists in rheumatology, dermatology, infectious diseases, wound care, vascular surgery, hematology, and oncology. Effective communication within the health care team is essential for accurate diagnosis and management of atypical ulcers. Active dialogue between providers can improve consult efficiency and ultimately lower the cost of care.

A treatment algorithm to identify therapeutic approaches for leg ulcers in patients with sickle cell disease.

Sickle cell leg ulcers (SCLUs) are a common complication of sickle cell disease (SCD). Patients who develop ulcers appear to have a more severe haemolysis-associated vasculopathy than individuals who do not develop them, and manifest other complications such as priapism and pulmonary hypertension. SCLUs are slow to heal and often recur, affecting both the emotional and physical well-being of patients. Here we summarise what is known about the pathophysiology of SCLUs, describe available treatment options and propose a treatment algorithm.
