Violaceous nodules of the extensor joints - a clinicopathological challenge.

Antineutrophilic cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a condition characterized by vessel inflammation and may have a variety of etiologies. Among these, cocaine and its common adulterant, levamisole, have been described to contribute to the development of AAV with distinct cutaneous manifestations. Classically, these manifestations involve purpuric or necrotic lesions involving the ears, nose, and extremities. However, we present a case of cocaine-induced AAV presenting with violaceous nodules on the dorsal hands in order to demonstrate that this condition may not always present with retiform purpura and skin necrosis.

Identifying Content Themes in Primary Care Physician and Rheumatologist Communications Within Electronic Consultations: A Qualitative Study.

OBJECTIVE: Electronic consultation (eConsult) communications between primary care physicians (PCPs) and rheumatologists may reveal common knowledge gaps and educational opportunities. The aim of our study was to identify content themes in PCP questions and rheumatology recommendations through analysis of eConsult and the need for rheumatology appointments and facilitated urgent visits post-eConsult. METHODS: A descriptive cross-sectional study involving qualitative and quantitative analysis of rheumatology eConsults in a single center was performed from May 1, 2019, to January 9, 2020. Conventional content analysis was used to derive content themes in PCP questions and rheumatology recommendations. We evaluated the proportion of eConsults, which included a need for rheumatology appointments and expedited visits through frequency counts. RESULTS: Among 120 rheumatology eConsults, six PCP questions and five rheumatology recommendation content themes were identified. The most common PCP question themes were the following: 1) joint pain, 2) suspected rheumatic disease differential, and 3) abnormal laboratory tests. The most common rheumatology recommendation or teaching themes were the following: 1) education on differential diagnoses of rheumatic diseases, 2) education on the specific rheumatic disease, and 3) laboratory test interpretation. The majority of eConsults (82%) recommended a subsequent rheumatology appointment, and 27% facilitated an expedited appointment. CONCLUSION: In this analysis of eConsults, we identified common knowledge gaps in PCPs and rheumatology educational topics, including differentiating inflammatory from noninflammatory arthritis, using caution in interpreting abnormal laboratory tests without clinical manifestations, managing chronic gout, evaluating elevated creatine phosphokinase levels, and differentiating C-reactive protein (CRP) from high-sensitivity CRP. Timely feedback through eConsult recommendations may allow for focused educational opportunities.

"If it helps someone, then I want to do it": Perspectives of persons living with dementia on research registry participation.

Registries are an important platform to which persons with dementia and other cognitive impairments can contribute to research studies. Registries also provide an opportunity for patients to stay informed about current studies. Engaging patients in registry development can increase sustainability of a registry and patient retention in clinical registries. We sought the perspective of persons with dementia and their accompanying family members about their registry participation experiences, barriers and facilitators to participation, and potential avenues for improvement of registry processes such as recruitment, data collection, and knowledge translation. Two semi-structured focus groups with persons with dementia and their family members (n = 18) were conducted and analyzed using thematic content analysis. Participants were recruited from an existing patient registry made up of patients currently being seen in a dementia assessment clinic. The main themes identified included altruistic motives with regards to registry participation; and access to and privacy of personal health information. As electronic health records are becoming more common, understanding barriers and facilitators from the perspectives of people with dementia is essential to inform the future development of cognitive condition-related registries. The results from our focus groups identified engagement strategies and solutions to overcome perceived barriers for individuals experiencing progressive cognitive decline to participate in longitudinal registry projects.

Management of perioperative hemostasis in a severe hemophilia A patient with inhibitors on emicizumab using global hemostasis assays.

BACKGROUND: Patients with severe hemophilia A and inhibitors are at risk of bleeding during invasive procedures. The standard of care for preventing perioperative bleeding has been replacement therapy with FVIII concentrates or for patients with high-titer inhibitors, bypassing agents. However, there is no consensus on the appropriate management of surgery in patients receiving the novel agent emicizumab. The aim of this study was to demonstrate a case of a patient on emicizumab undergoing major surgery with bypassing agents with preoperative use of the thrombin generation assay (TGA) and thromboelastography (TEG). METHODS: We report a patient with hemophilia A with inhibitors who had undergone a total knee replacement while on emicizumab combined with a bypassing agent. We utilized TEG and TGA to determine which bypassing agent to choose as well as to inform about the ideal dose. RESULTS: We elected to use recombinant FVIIa as a bypassing agent for the surgery based upon the TGA results. CONCLUSION: The TGA can be utilized to support decision-making in patients on emicizumab undergoing major surgery to both predict efficacy and potentially minimize the risk of thrombotic events.

Perioperative mannan-binding lectin (MBL) patterns in cardiac surgery may correlate with the clinical outcomes in MBL deficient patients.

Previously we reported a case of abrupt change of postoperative mannan-binding-lectin (MBL) in a patient with preexisting MBL deficiency who expired shortly after cardiac surgery. Herein we report additional cases of 3 more patients with preexisting MBL deficiency who underwent cardiac surgery. Analysis of their blood samples from the perioperative period showed their MBL levels were abruptly increased at 24 hours after surgery. However, 2 patients had a subsequent drop of MBL at 48 hours, and both expired. These data indicated that the postoperative decrease of MBL may have been related with an unfavorable outcome after cardiac surgery.
