Interstitial lung disease and pancreatic exocrine insufficiency in CADDS: Phenotypic expansion and literature review.

Contiguous / deletion syndrome (CADDS) is a rare deletion syndrome involving two contiguous genes on Xq28, and (formerly known as ). Only nine individuals with this diagnosis have been reported in the medical literature to date. Intragenic loss-of-function variants in cause the deafness, dystonia, and cerebral hypomyelination syndrome (DDCH).

POLR1A variants underlie phenotypic heterogeneity in craniofacial, neural, and cardiac anomalies.

Heterozygous pathogenic variants in POLR1A, which encodes the largest subunit of RNA Polymerase I, were previously identified as the cause of acrofacial dysostosis, Cincinnati-type. The predominant phenotypes observed in the cohort of 3 individuals were craniofacial anomalies reminiscent of Treacher Collins syndrome. We subsequently identified 17 additional individuals with 12 unique heterozygous variants in POLR1A and observed numerous additional phenotypes including neurodevelopmental abnormalities and structural cardiac defects, in combination with highly prevalent craniofacial anomalies and variable limb defects.

Primary Sjögren syndrome and development of another autoimmune rheumatic disease during the follow-up.

Background: Primary Sjögren syndrome (pSS) is a chronic autoimmune disease with its main target being exocrine glands, and is the connective tissue disease more frequently associated with other autoimmune diseases. The aim of this study was to assess the frequency of another autoimmune rheumatic disease (ARD) developed in primary Sjögren syndrome (pSS) patients and to describe it's clinical, serological and histologic characteristics.

Materials And Methods: This is a retrospective cohort study.

Inherited variants in CHD3 show variable expressivity in Snijders Blok-Campeau syndrome.

Purpose: Common diagnostic next-generation sequencing strategies are not optimized to identify inherited variants in genes associated with dominant neurodevelopmental disorders as causal when the transmitting parent is clinically unaffected, leaving a significant number of cases with neurodevelopmental disorders undiagnosed.

Methods: We characterized 21 families with inherited heterozygous missense or protein-truncating variants in CHD3, a gene in which de novo variants cause Snijders Blok-Campeau syndrome.

Results: Computational facial and Human Phenotype Ontology-based comparisons showed that the phenotype of probands with inherited CHD3 variants overlaps with the phenotype previously associated with de novo CHD3 variants, whereas heterozygote parents are mildly or not affected, suggesting variable expressivity.

Work productivity and activity impairment in patients with primary Sjögren's syndrome.

Objectives: In this observational, analytical, cross-sectional study we aimed to describe the impact of primary Sjögren's syndrome (pSS) on work productivity and activities of daily living (ADL) to assess the association between ADL impairment and clinical manifestations and to compare ADL impairment according to patients' socioeconomic condition.

Methods: Patients diagnosed with pSS attending 11 centres from Argentina were included. To evaluate work productivity and ADL impairment, a work productivity and activity impairment questionnaire (WPAI) was used.

Evaluation of the Educational Needs in Argentine Patients with Rheumatoid Arthritis Using the SpENAT Questionnaire.

Background: The SpENAT, a Spanish version of the Educational Needs Assessment Tool, is a self-completed questionnaire that assesses educational needs (ENs) with the purpose of providing tailored and patient-centered information. It consists of 39 questions grouped into the 7 following domains: Pain management, Movement, Feelings, Arthritic process, Treatments, Self-help measures and Support system.

Objectives: The objective of the study was to describe the ENs of rheumatoid arthritis (RA) patients using the SpENAT and to determine the main sources of information consulted by these patients.

Primary Sjögren's syndrome and pregnancy: A report of 18 cases.

Unlabelled: Primary Sjögren's syndrome (pSS) is a condition that predominantly affects women. Reports of pregnancy outcome in these patients are limited and contradictory.

Objective: To describe pregnancy characteristics and outcomes and newborn morbidity in women with pSS.
