An unusual case of late-onset systemic lupus erythematosus presenting with digital gangrene

@#Digital gangrene is an uncommon initial manifestation of systemic lupus erythematosus (SLE) and rarely in late-onset disease. This case presents a 50-year-old woman who developed digital gangrene and was subsequently diagnosed with SLE. Early treatment with immunosuppression and anticoagulation halted the progression of the digital ischemia. This case highlights that late-onset SLE, often described as having a more benign and insidious course, can also present with catastrophic limb-threatening manifestations.

Cáncer de mama triple negativo, abortos a repetición e isquemia digital grave / Triple negative breast cancer, repeated abortions and severe digital ischemia

Resumen El presente caso corresponde a una mujer con antecedentes de tres abortos de menos de 10 semanas y cáncer de mama, que desarrolló isquemia digital grave luego del segundo ciclo de capecitabina. Se determinó la presencia de anticuerpos antifosfolipídicos positivos. Dado que las pacientes con síndrome antifosfolipídico obstétrico tienen incremento del riesgo de desarrollar neoplasia y que la isquemia digital grave puede ser la forma de presentación del síndrome antifosfolipídico en los pacientes con cáncer, se presenta el caso para remarcar el beneficio de pesquisar y realizar un diagnóstico temprano de estas características de la enfermedad.

Abstract The present case corresponds to a woman with history of three miscarrieges less than10 weeks and breast cancer, who develops severe digital ischemia after the second cycle of capecitabine. Positive antiphospholipid antibodies were determined. Patients with obstetric antiphospholipid syndrome have an increased risk of developing cancer, and severe digital ischemia could be an unusual form of presentation of the antiphospholipid syndrome in patients with cancer. This case is presented to highlight the benefit of researching and making an early diagnosis of these characteristics of the disease.

A mimic of soft tissue infection: intra-arterial injection drug use producing hand swelling and digital ischemia / 世界急诊医学杂志（英文）

BACKGROUND: Inadvertent intra-arterial injection of illicit substances is a known complication of injection drug use and can lead to severe complications, including infection, ischemia and compartment syndrome. Identifying complications of intra-arterial injection can be difficult, as clinical manifestations overlap with other more common conditions such as cellulitis and soft tissue infection, and a history of injection drug use is frequently not disclosed. METHODS: A 37-year-old male patient presented with 24 hours of right hand pain, erythema and swelling. Despite classic "track marks", he denied a history of injection drug use, and vascular insults were not initially considered. After failing to respond to three days of aggressive treatment for suspected deep-space infection, an arteriogram demonstrated findings consistent with digital ischemia of embolic etiology. RESULTS: As a result of the delay in diagnosis, the lesion was not amenable to reperfusion and the patient required amputation of the distal digit. CONCLUSION: Practitioners should be alert to the possibility of intra-arterial injection and resulting complications when evaluating unusual extremity infections or unexplained ischemic symptoms, even in the absence of a definite history of injection drug use.

Foot Necrosis Following Percutaneous Cannulation of the Dorsalis Pedis Artery: A Case Report / 대한구급학회지

Arterial canuulation is generally used to monitor blood pressure and sample blood for gas analysis. Radial and dorsalis pedis arteries are commonly used for arterial cannulation. It is a simple, safe, and uncomplicated procedure, but some complications have been reported, including bleeding, hematoma, infection, pseudoaneurysm, and thromboembolism. Although thromboembolism is not common, it could be serious because it can lead to digital ischemia and necrosis. We present a case of foot necrosis following dorsalis pedis artery cannulation in a 65-year-old patient who underwent small bowel resection.

Finger Necrosis Following Percutaneous Radial Artery Cannulation: A case report / 대한마취과학회지

Anesthegiologists commonly use arterial cannulation for both close blood pressure monitoring and repeated blood sampling for gas analysis. Radial artery cannulation is generally thought of as a safe and uncomplicated procedure, however, some possible complications have been reported. These include bleeding, hematoma, infection, pseudoaneurysm and thromboembolism, which do not usually result in any serious clinical problems. Although it is not common, thromboembolism could be serious because it can lead to digital ischemia and necrosis. We report here a case of finger necrosis following radial artery cannulation in a patient who underwent radical hysterectomy under general anesthesia.
