Sjögren's disease activity associates with cardiovascular disease and monoclonal gammopathy: a university cohort study of disease activity and comorbidities.

Background: We used the University of Wisconsin cohort to determine the extent to which the EULAR Sjögren's syndrome disease activity index (ESSDAI) was associated with comorbidities that contribute to mortality.

Methods: Our University of Wisconsin, Madison cohort had 111 patients with Sjögren's Disease (SjD) by 2016 ACR/EULAR criteria and 194 control patients with sicca. Our study was performed from March 1st, 2020 through April 1st, 2023.

What Bedside Skills Could the Modern Rheumatologist Possess? Part II. "Certain Technical Procedures".

Rheumatologists have never been reluctant to adopt procedures that might enhance their diagnostic or therapeutic powers. Their propensity to penetrate the joints of the patients they were treating set them apart from the general internist. Since the 1980s, when a chance to look inside the joints they were treating attracted a few rheumatologists, other things that could be done at the bedside emerged with now an array of bedside procedures that could be part of a rheumatologist's skill set.

What Bedside Skills Could the Modern Rheumatologist Possess? Part I. The Basics.

The hands-on aspect of rheumatologic practice serves to balance its more cerebral features with the everyday necessity to touch patients to assess their condition, obtain samples for diagnosis, and deliver therapy, all cementing the important bond between patient and physician. Factors over recent years, ranging from the intercession of the electronic medical record to COVID, have weakened this bond, which we must restore if the practice of rheumatology is to return to previous levels of satisfaction. We review herein, in 2 parts, the many ways rheumatologists may interact physically with patients, with hope that pursuit of these measures can enhance satisfaction of physician and patient alike.

Bedside labial salivary gland biopsy (LSGBx: Lip biopsy): An update for rheumatologists.

Retrieval of minor salivary glands from a labial submucosal site through a minimally invasive bedside procedure was first described nearly 60 years ago and remains an attractive alternative to more invasive surgical procedures to obtain salivary gland tissue for pathologic examination. Examination of glands for features of Sjögren's has constituted the primary use of this procedure but other systemic disorders can affect minor salivary glands and their diagnoses can be supported by biopsy. Performance of the procedure does not require specialized training in head and neck surgery or dentistry, only simple wound closure skills.

Is It Time to Bring Back Knee Washout?

Washout of knee joint contents, whether by arthrotomy, arthroscopy, or percutaneous methods, can remove phlogistic material contributing to the problem at hand. Observations dating from the turn of the last century coupled with multiple trials suggest such that an intervention can be useful in the management of osteoarthritis, inflammatory arthropathies, crystal arthritis, and septic arthritis. We suggest that this intervention-applicable at the bedside with minimal cost, preparation, or expertise-be reconsidered as an adjunct in management of these disorders.

Regarding Arthroscopy: Can Orthopedists and Rheumatologists Be Friends?

Background/objective: Rheumatologists' interest in arthroscopy began before the 1980s, when many era practitioners began to take up the procedure in earnest. Some of the important players in pre-World War II explorations of arthroscopy were rheumatologists, and the father of modern arthroscopy Makei Watanabe counted many rheumatologists among his postwar students, who were publishing about arthroscopic insights into rheumatic conditions in the 1960s and 1970s. We chose to review this evolution to demonstrate the diverging interests of rheumatologists and orthopedists in arthroscopy and emphasize the chances for reconciliation and cooperation.

Will rheumatologists ever pick up the arthroscope again?

Conditions prompting physicians and surgeons first adapting endoscopes to peer into joints were mainly the sort of synovial conditions that would concern today's rheumatologists. Rheumatologists were among the pre-World War II pioneers developing and documenting arthroscopy. The post-War father of modern arthroscopy, Watanabe, found rheumatologists among his early students, who took back the technique to their home countries, teaching orthopedists and rheumatologists alike.

Arthroscopy in rheumatology: where have we been? Where might we go?

The aim of our manuscript is to illustrate the past, present and future role of rheumatologists performing arthroscopy. Doctors first began adapting endoscopes to inspect joints to assess synovial conditions that concern rheumatologists. Rheumatologists were among the pioneers developing arthroscopy.

Synovial Biopsy in the Diagnosis of Crystal-Associated Arthropathies.

Background/ Objective: This study seeks to assess the utility of synovial biopsy in the diagnosis of crystal-associated arthropathies (CAAs) in a clinical setting.

Methods: In this retrospective study, we reviewed biopsy reports involving synovial tissue between 1988 and 2015. We then reviewed the records of patients where the biopsy was performed for a clinical suspicion of CAA-the clinical group-and calculated the frequency of a positive diagnosis.

Transcriptional Profiling of Synovial Macrophages Using Minimally Invasive Ultrasound-Guided Synovial Biopsies in Rheumatoid Arthritis.

Objective: Currently, there are no reliable biomarkers for predicting therapeutic response in patients with rheumatoid arthritis (RA). The synovium may unlock critical information for determining efficacy, since a reduction in the numbers of sublining synovial macrophages remains the most reproducible biomarker. Thus, a clinically actionable method for the collection of synovial tissue, which can be analyzed using high-throughput strategies, must become a reality.

Genome-wide Association Analysis of Psoriatic Arthritis and Cutaneous Psoriasis Reveals Differences in Their Genetic Architecture.

Psoriasis vulgaris (PsV) is a common inflammatory and hyperproliferative skin disease. Up to 30% of people with PsV eventually develop psoriatic arthritis (PsA), an inflammatory musculoskeletal condition. To discern differences in genetic risk factors for PsA and cutaneous-only psoriasis (PsC), we carried out a genome-wide association study (GWAS) of 1,430 PsA case subjects and 1,417 unaffected control subjects.

Genome-wide association analysis identifies three psoriasis susceptibility loci.

We carried out a meta-analysis of two recent psoriasis genome-wide association studies with a combined discovery sample of 1,831 affected individuals (cases) and 2,546 controls. One hundred and two loci selected based on P value rankings were followed up in a three-stage replication study including 4,064 cases and 4,685 controls from Michigan, Toronto, Newfoundland and Germany. In the combined meta-analysis, we identified three new susceptibility loci, including one at NOS2 (rs4795067, combined P = 4 × 10⁻¹¹), one at FBXL19 (rs10782001, combined P = 9 × 10⁻¹⁰) and one near PSMA6-NFKBIA (rs12586317, combined P = 2 × 10⁻⁸).

Ultrasound of the knee during voluntary quadriceps contraction: a technique for detecting otherwise occult effusions.

Objective: To describe 1) a technique that can detect synovial effusions not seen on static ultrasound (US) examination and 2) the characteristics of patients with knee osteoarthritis (OA) for whom this technique proved useful.

Methods: From reviewed records of 76 patients with knee OA (112 knees) that we had seen for US-guided injections over a defined period, we found 45 knees with no detectable effusion on static US, of which 18 (14 patients) showed fluid when scanned during voluntary quadriceps contraction. For all patients, we had recorded effusion features (physical examination, presence and size on US), and success of joint entry was determined by getting synovial fluid and/or seeing an air echo or inflow of injected material.

Self-directed learning of basic musculoskeletal ultrasound among rheumatologists in the United States.

Objective: Because musculoskeletal ultrasound (MSUS) is highly user dependent, we aimed to establish whether non-mentored learning of MSUS is sufficient to achieve the same level of diagnostic accuracy and scanning reliability as has been achieved by rheumatologists recognized as international experts in MSUS.

Methods: A group of 8 rheumatologists with more experience in MSUS and 8 rheumatologists with less experience in MSUS participated in an MSUS exercise to assess patients with musculoskeletal abnormalities commonly seen in a rheumatology practice. Patients' established diagnoses were obtained from chart review (gout, osteoarthritis, rotator cuff syndrome, rheumatoid arthritis, and seronegative arthritis).

Evaluating the effect of image preprocessing on an information-theoretic CAD system in mammography.

Rationale And Objectives: In our earlier studies, we reported an evidence-based computer-assisted decision (CAD) system for location-specific interrogation of mammograms. A content-based image retrieval framework with information theoretic (IT) similarity measures serves as the foundation for this system. Specifically, the normalized mutual information (NMI) was shown to be the most effective similarity measure for reduction of false-positive marks generated by other prescreening mass detection schemes.

Prevalence of antigliadin antibodies in patients with psoriasis is not elevated compared with controls.

Background: Antigliadin antibodies (AGAs) are markers of celiac sprue but may have autoimmune implications in the absence of gastrointestinal disease. There is anecdotal evidence to suggest that gluten sensitivity may play a role in psoriasis, and patients with psoriasis in Europe have been reported to improve on a gluten-free diet.

Objective: To assess whether patients with psoriasis in the US have an increased prevalence of elevated AGAs.
