Bilateral facial paralysis as a rare neurological manifestation of primary Sj ögren’s syndrome: case-based review

AbstractPrimary Sj ögren’s syndrome (pSS) is a chronic autoimmune disorder associated with a variety of systemic presentations. Varied neurological dysfunctions of newly diagnosed adult patients with pSS have been observed in recent years. We aimed to describe a rare case of acute bilateral facial paralysis diagnos ed with pSS for the first time and review the previous studies including similar cases. A 69-year-old female, who had experienced ocular and oral dryness for more than 10 years, presented with bilateral facial palsy. Her laboratory test results showed positive anti-Ro (SSA) and anti-Ro-52 antibodie s. Ophthalmic examination and test of saliva secretion verified xerophthalmia and xerostomia, respectively. Other possibilities of Lyme disease, Möbius syndrome, tumor, bilateral temporal bone fracture, Guillain–Barré syndrome, central nervous system lymphoma and HIV infection were ruled out. A diagnosis of pSS associated with bilateral facial paralysis was made. The literature review revealed one article describing a similar patient. Our case was the only one suffering from acute bilateral facial palsy without other nerve involvement. The presence of such patients reveals that pSS is an u nderlying cause of acute bilateral facial paralysis.

CONCLUSIONS: As the present study was the first investigation on the coagulation status in patients with AA, elevated D-dimer levels in alopecia areata may suggest a deficient coagulation in these patients that may contribute to an increase in the risk of thrombosis. Further studies are needed to evaluate this hypothesis using a larger sample size. PMID: 33034439 [PubMed - as supplied by publisher]

We report the rare case of a patient co-existing NS and DLBCL. DLBCL might be pathogenesis of NS; the findings are supported by the presence of MN, an underlying malignancy (DLBCL), and the lack of anti-PLA2R antibodies. Although further investigation is warranted, our case suggests that DLBCL is a possible cause of secondary MN. PMID: 33028760 [PubMed - in process]

Authors: Cáceres-Perkins W, Cabanillas F, San Vicente G, Rivera-Franceschini C, Sobrino-Najul E, Vega-Vázquez LI, Conde-Sterling D Abstract Mucosa-associated lymphoid tissue (MALT) lymphomas are B-cell neoplasms that commonly affect the gastrointestinal (GI) tract, usually the stomach. In most cases, extranodal marginal zone lymphoma (ENMZL) is an indolent disease. Bone marrow involvement is common with MALT lymphoma accompanied by paraproteinemia; such involvement impels disease progression. Here, we present the case of an 82-year-old Hispanic patient with long-standing ENMZL in whom the gastric site...

CONCLUSION: Our data suggest that these two polymorphisms do not contribute to AD in the population from the Mersin region of the Eastern Mediterranean. Further studies with larger sample sizes must be conducted to ascertain the association between the 2 polymorphisms. PMID: 33031695 [PubMed - as supplied by publisher]

AbstractRheumatoid arthritis (RA) is a progressive autoimmune inflammatory disease affecting 1% of the population with three times as many women as men. As many as 86% of patients suffering from RA have cervical spine involvement. Synovial inflammation in the cervical spine causes instability and injuries including atlantoaxial subluxation, retroodontoid pannus formation, cranial settling, and subaxial subluxation. While many patients with cervical spine involvement are asymptomatic, symptomatic patients often present with nonspecific symptoms resulting from inflammation and additional secondary symptoms that are due to co...

ConclusionsWith the experience we gained from our recent studies, we think that miRNA-204 may be a significant biomarker in autoimmune diseases. Our study is the first study between IgAV and miRNAs in children. More studies are needed to reveal this relationship.Key Points•This is the first paper to show the relationship between miRNAs and childhood IgAV.•It will provide a new perspective to evaluate the pathogenesis of the disease.
