Macular lymphocytic arteritis (MLA) is an indolent cutaneous small-medium-vessel vasculitis characterized by widespread asymptomatic livedo racemosa. A number of serologic abnormalities have been reported including an elevated erythrocyte sedimentation rate and antibodies associated with antiphospholipid antibody syndrome. We present a case of MLA with multiple serologic abnormalities, including those that have yet to be reported, such as anti-U1 ribonucleotide protein, anti-RNA polymerase III, anti-smith, and anti-proteinase 3 antibodies. We also provide a brief review of this unfamiliar entity with a focus on the appropriate workup.

Systemic sclerosis sine (latin: without) scleroderma (ssSSc), also called visceral scleroderma, is characterized by internal organ involvement and abnormal serologic abnormalities in the complete or partial absence of cutaneous manifestations of systemic sclerosis.1,2 Pulmonary involvement in scleroderma consists of interstitial lung disease and pulmonary hypertension. Usual interstitial pneumonia (45.

The domestic dog () is a competent host for () infection but no ante mortem diagnostic tests have been fully validated for this species. The aim of this study was to compare the performance of ante mortem diagnostic tests across samples collected from dogs considered to be at a high or low risk of sub-clinical infection. We previously tested a total of 164 dogs at a high risk of infection and here test 42 dogs at a low risk of infection and 77 presumed uninfected dogs with a combination of cell-based and/or serological diagnostic assays previously described for use in non-canid species.

Objective: In systemic sclerosis (SSc), absent contractility (AC) rather than ineffective esophageal motility on manometry is associated with a severe esophageal and extraintestinal phenotype. We sought to determine whether slow esophageal transit on scintigraphy associates with a comparable clinical phenotype to that of AC on manometry, as scintigraphy may serve as a noninvasive approach to risk-stratify patients with SSc.
Methods: Clinical, demographic, and serologic features were compared between patients with and without delayed esophageal transit on scintigraphy.
Primary intestinal lymphangiectasia (PIL) is a rare protein-losing gastroenteropathy characterized by diffuse or localized ectasia of the enteric lymphatics, which can be accompanied by lymphatic abnormalities in other parts of the body. This condition results in hypoalbuminemia, hypogammaglobulinemia, and lymphopenia due to the abnormal leakage of lymphatic fluid into the gastrointestinal tract. As there are no specific serological or radiological tests available, the gold standard for diagnosing intestinal lymphangiectasia is endoscopic examination with histopathological examination of intestinal biopsy specimens.

Background: Human activities, such as urbanization and climate change, have facilitated the spread of arbovirus-carrying vectors, disproportionately affecting vulnerable traditional Indigenous communities.
Objective: To explore the relationships between subclinical myocardial dysfunction, assessed by global longitudinal strain (GLS), and comprehensive arbovirus serology in an Indigenous population, while also describing the serological and epidemiological profile of dengue, chikungunya, and Zika viruses.
Methods: This ancillary study is part of the first phase (2016-2017) of the Project of Atherosclerosis among Indigenous Populations (PAI), a cross-sectional study involving participants from two Indigenous communities with different degrees of urbanization and a highly urbanized city in Northeast Brazil.
