Emperipolesis is not pathognomonic for Rosai-Dorfman disease: Rhinoscleroma mimicking Rosai-Dorfman disease, a clinical series

Background and Objective: Rosai-Dorfman disease (RDD) are usually misdiagnosed because of rarity and nonspecific clinical and radiological features. The aim of our study is to explore the clinical and imaging characteristics of RDD to improve diagnostic accuracy. Methods: Clinical and imaging data in 10 patients with RDD were retrospectively analyzed. 7 patients were underwent CT scanning and 3 patients were underwent MR examination. Results: 8 (8/10) patients presented with painless enlarged lymph nodes (LNs) or mass. 3 cases were involved with LNs, 5 cases were involved with extra-nodal tissues, and the remaining 2 cases were involved with LNs and extra-nodal tissue simultaneously. In enhanced CT images, enlarged LNs displayed mild or moderate enhancement, and 2 cases showed heterogeneous ring-enhancement. MR features of 3 patients with extra-nodal RDD, 2 cases showed a mass located in the subcutaneous and anterior abdominal wall respectively, and 1 case showed an intracranial mass. Besides, all lesions showed high signal foci on DWI images, and were characterized by marked heterogeneous enhancement with blurred edge. The dural/fascia tail sign and dilated blood vessels could be seen around all the lesions on enhanced MRI. Radiological features of 2 cases with LN and extranodal tissue involved, one case presented with the swelling and thickening of pharyngeal lymphoid ring and nasopharynx, meanwhile with enlarged LNs in bilateral submandibular area, neck and abdominal cavity, and also companied with osteolytic lesion in right proximal humerus. All these LNs displayed mild and moderate enhancement on CT images. Another case showed enlarged LNs in bilateral neck accompanied with soft tissue mass in the sinuses. Conclusions: RDD occurred commonly in young and middle-aged men and presented with painless enlarged LNs or mass.RDD had a huge diversity of imaging findings, which varied with different location. The radiological features, such as small patches of high signal foci in the masses on DWI images, heterogeneous enhancement and blood vessels around the masses, are helpful in diagnosis of extranodal RDD.

Community Trauma

Background: REBOA has become an established adjunct to hemorrhage control. Prospective data sets are being collected, primarily from large, high volume trauma centers. There are limited data, and guidelines, to guide implementation and use outside of highly resourced environments. Smaller centers interested in adopting a REBOA program could benefit from closing this knowledge gap. Methods: A clinical series of cases utilizing REBOA from Grand Strand Medical Center, Myrtle Beach, South Carolina were reviewed. This represents early data from a busy community trauma center (ACS Level 2), from January 2017 to May 2018. Seven cases are identified and reported on, including outcomes. Considerations and ‘lessons learned’ from this early institutional experience are commented on. Results: REBOA was performed by trauma and acute care surgeons for hemorrhage and shock (blunt trauma n=3, penetrating trauma n=2, no- trauma n=2). All were placed in Zone 1 (one initially was placed in zone 3 then advanced). Mean (SD) systolic pressure (mmHg) before REBOA was 43 (30); post REBOA pressure was 104 (19). N=4 were placed via an open approach, n=3 percutaneous (n=2 with ultrasound). All with arrest before placement expired (n=3) and all others survived. Complications are described. Conclusions: REBOA can be a feasible adjunct for shock treatment in the community hospital environment, with outcomes comparable to large centers, and can be implemented by acute care and trauma surgeons. A rigorous process improvement program and critical appraisal process are critical in maximizing benefit in these centers.

Biodegradable Magnesium

Biodegradable magnesium-based implants are innovative alternatives that potentially eliminate the need for implant removal. Recent studies have demonstrated the osteogenic properties and bacterial inhibition potentials of magnesium screws. We reported a clinical series of three elbow fracture cases, where magnesium screws were used in the treatment of one radial head and two capitellum fractures. Postoperative clinical courses were uneventful, and fracture healing occurred within 3 months. In all cases, radiolucencies were observed around implants especially in the screw head region at 2 months post-operation, but disappeared with consolidation at 1 year post-operation. All patients achieved near normal range of motion, minimal symptoms and good functional outcomes. No complication such as failure of fixation, loss of reduction, malunion or infection was seen. No implant revision or removal was necessary. Magnesium bioabsorbable screws are shown to be a viable option for these fractures.
