Three-dimensional imaging of the mucosa of the lower lip and labial minor salivary glands is demonstrated in vivo using swept source optical coherence tomography (OCT) system at 1310 nm with modified interface. Volumetric data sets of the inner surface of the lower lip covering ~230 mm(2) field are obtained from patients with Sjögren's syndrome and a control group. OCT enables high-resolution visualization of mucosal architecture using cross-sectional images as well as en-face projection images. Comprehensive morphometry of the labial minor salivary glands is performed, and statistical significance is assessed. Statistically significant differences in morphometric parameters are found when subgroups of patients with Sjögren's syndrome are analyzed.

Objectives: Orofacial cleft (OC) can be classified into syndromic orofacial cleft (SOC) and non-syndromic orofacial cleft (NSOC), depending on whether there are other congenital deformities. Craniosynostosis, the premature closure of cranial sutures, is a common phenotype of SOC resulting in abnormal ossification of skull and brain development disorders. Its correlation with OC offers a promising approach to identify susceptibility genes for NSOC by examining causative genes of SOCs with craniosynostosis.

Introduction: Sjögren's syndrome (SS) presents complex diagnostic challenges due to its multi-organ involvement, often leading to misdiagnosis, which can result in unnecessary treatments, elevated healthcare costs, and significant impacts on patient quality of life. Accurate diagnosis is therefore critical, utilising ACR/EULAR criteria that include both labial minor salivary gland (LMSG) biopsy and anti-SSA antibodies.
Methods: This retrospective study analysed medical records of 87 adults suspected of primary SS, who underwent both anti-SSA serology and LMSG biopsy.
Background: Much data informing sex differences in atrial fibrillation (AF) comes from Western cohorts. In this analysis, we describe sex differences in Kerala, India, using the Kerala-AF registry-the largest AF registry from the Indian subcontinent.
Methods: Patients aged ≥18 years were recruited from 53 hospitals across Kerala.

Objective: To assess the effectiveness of labial minor salivary gland biopsy (LSGB) alone or in combination with punch skin biopsy (SB) for the detection of amyloid deposits in hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN).
Methods: In this single-center retrospective study, Congo red staining of minimal invasive LSGB (4 mm) and SB (3 mm) was assessed in ATTRv-PN patients consecutively evaluated between 2012 and 2023.
Results: Histopathological data of 171 ATTRv-PN, including 49 early-onset p.
