A case report of a rare proximal phalanx metastasis from a primary lung carcinoma is described. The presenting symptom of the patient was pain in the proximal phalanx of the index finger. Radiographs at the time of presentation were unremarkable, and no diagnosis was provided. Because of increasing pain and eventual swelling, the patient presented for emergency assessment. Radiographs, less than 3 months after initial assessment, demonstrated a large lytic lesion within the proximal phalanx. Biopsy of the lesion documented a large cell malignancy consistent with a poorly differentiated adenocarcinoma. Subsequent investigations documented an occult lung neoplasm. The patient underwent palliative ray resection followed by the initiation of palliative chemotherapy for the primary carcinoma. A brief review of literature regarding acrometastases is provided and the potential benefit of early positron emission tomography scanning is discussed.

ObjectivesPoint-of-care ultrasound-guided regional anaesthesia (POCUS-GRA) provides safe, rapid analgesia for older people with hip fractures but is rarely performed in the emergency department (ED). Self-perceived inadequate training and time to perform POCUS-GRA are the two most important barriers. Our objective is to assess the feasibility of a proposed multicentre, stepped-wedge cluster randomised clinical trial (RCT) to assess the impact of a knowledge-to-practice (KTP) intervention on delirium.DesignOpen-label feasibility study.SettingAn academic tertiary care Canadian ED (annual visits 60 000).ParticipantsEmergency physicians working at least one ED shift per week, excluding those already performing POCUS-GRA more than four times per year.InterventionA KTP intervention, including 2-hour structured training sessions with procedure bundle and email reminders.Primary and secondary outcome measuresThe primary feasibility outcome is the proportion of eligible physicians that completed training and subsequently performed POCUS-GRA. Secondary outcome is the time needed to complete POCUS-GRA. We also test the feasibility of the enrolment, consent and randomisation processes for the future stepped-wedge cluster RCT (NCT02892968).ResultsOf 36 emergency physicians, 4 (12%) were excluded or declined participation. All remaining 32 emergency physicians completed training and 31 subsequently treated at least one eligible patient. Collectively, 27/31 (87.1%) performed 102 POCUS-GRA blocks (range 1–20 blocks per physician). The median (IQR) time to perform blocks was 15 (10–20) min, and reduction in pain was 6/10 (3–7) following POCUS-GRA. There were no reported complications.ConclusionOur KTP intervention, consent process and randomisation were feasible. The time to perform POCUS-GRA rarely exceeded 30 min, Our findings reinforce the existing data on the safety and effectiveness of POCUS-GRA, mitigate perceived barriers to more widespread adoption and demonstrate the feasibility of trialling this intervention for the proposed stepped-wedge cluster RCT.Trial registration numberClinicaltrials.gov #02892968
