Deep Neural Network for Cardiac Magnetic Resonance Image Segmentation.

The analysis and interpretation of cardiac magnetic resonance (CMR) images are often time-consuming. The automated segmentation of cardiac structures can reduce the time required for image analysis. Spatial similarities between different CMR image types were leveraged to jointly segment multiple sequences using a segmentation model termed a multi-image type UNet (MI-UNet).

Primary Immunodeficiency in a 74-Year-Old Male With Chronic Productive Cough: A Rare Case of Common Variable Immunodeficiency.

Common variable immunodeficiency (CVID) is the most common symptomatic primary immunodeficiency. It presents with variable degrees of immunodeficiency resulting in a variety of clinical presentations and complications. This report describes the case of newly diagnosed CVID in a 74-year-old man with no history of recurrent infections or hospitalizations.

Paroxysmal Sympathetic Hyperactivity in a 73-Year-Old Female With Acute Myeloid Leukemia.

Paroxysmal Sympathetic Hyperactivity (PSH) is a syndrome of recurrent exaggerated sympathetic responses in combination with motor features typically observed in the setting of traumatic brain injury and rarely seen without it. Here, we present a case of PSH in a 73-year-old female with acute myeloid leukemia (AML) without any brain injuries presenting with recurrent intermittent episodes of tachycardia, tachypnea, hypertension, fever, dystonia. These episodes resolved with clonidine and clonazepam thus confirming the diagnosis of PSH.

A Rare Case of Serrated Polyposis Syndrome with the MSH6 and SMARCA4 variants.

Unlabelled: Serrated polyposis syndrome (SPS) is the most common form of polyposis syndrome and has been shown to increase the risk of colorectal cancer (CRC). The genetic pathway of CRC in SPS is different from the classic adenomatous polyposis coli (APC) pathway, which accounts for 70-80% of cases of CRC. Most commonly, SPS mutations include BRAF and KRAS, with activation of the RAS-RAF-MAP kinase pathway involved in the pathogenesis of serrated lesions.

Paraneoplastic Raynaud's Phenomenon as an Initial Manifestation of Lung Cancer?

Unlabelled: Paraneoplastic Raynaud's phenomenon has often been reported in leukaemia, lymphoma and sarcoma. Nevertheless, an association with lung cancer is not frequently reported in the literature even though lung cancer is a common malignancy. We present a case of paraneoplastic Raynaud's phenomenon as the presenting feature of underlying lung malignancy.

Leukocytoclastic Vasculitis as a Rare Manifestation of Staphylococcal Osteomyelitis.

Leukocytoclastic vasculitis (LCV), also known as small-vessel cutaneous vasculitis, is rarely seen in the setting of staphylococcal infection without bacteremia. Here, we present a case of LCV in a 61-year-old male with chronic staphylococcal osteomyelitis without any evidence of bacteremia. The rash resolved with the treatment of osteomyelitis.

Rheumatology Patient Satisfaction With Telemedicine During the COVID-19 Pandemic in the United States.

The spread of COVID-19 in the United States has led to the use of virtual visits in lieu of in-person care for the high-risk population of patients in rheumatology. We asked patients to score their satisfaction with these visits and if they would have preferred in-person care instead. Of 679 patients seen in May 2020, 512 (75.

Rheumatoid Vasculitis as an Initial Presentation of Rheumatoid Arthritis.

Unlabelled: Rheumatoid vasculitis is a rare, extra-articular manifestation that can be seen in long-standing rheumatoid arthritis. Here we present the case of a 51-year-old man who presented with arthralgias, skin rash, dyspnoea and generalized leg swelling and who was diagnosed with rheumatoid arthritis flare.

Learning Points: Extra-articular manifestations like rheumatoid vasculitis and pericarditis rarely present as initial manifestations of rheumatoid arthritis.

Delayed-onset Necrotizing Myositis following COVID-19 Infection.

Unlabelled: As the numbers of cases of COVID-19 continue to rise, the heterogeneity of its clinical manifestation continues to increase. Here, we describe a case of delayed-onset, biopsy-proven necrotizing myositis following infection with SARS-CoV-2.

Learning Points: SARS-CoV-2 may be associated with late-onset necrotizing myositis, mimicking autoimmune inflammatory myositis.

Impact of Aortic Valve Replacement for Severe Aortic Stenosis on Perioperative Outcomes Following Major Noncardiac Surgery.

Objective: To compare the incidence of major adverse cardiac events and death among severe aortic stenosis patients with and without aortic valve replacement (AVR) before noncardiac surgery.

Patients And Methods: We retrospectively evaluated 491 severe aortic stenosis patients undergoing non-emergency/non-urgent elevated-risk noncardiac surgery between January 1, 2000, and December 31, 2013, including 203 patients (mean age, 74±10 years, 63.5% men) with previous AVR and 288 patients (mean age, 77±12 years, 55.
