An adult patient with Tatton-Brown-Rahman syndrome caused by a novel DNMT3A variant and axonal polyneuropathy.

Tatton-Brown-Rahman syndrome (TBRS) is a rare autosomal dominant overgrowth syndrome first reported in 2014 and caused by pathogenic variants in the DNA methyltransferase 3A (DNMT3A) gene. All individuals reported to date share a phenotype of somatic overgrowth, dysmorphic features, and intellectual disability. Peripheral neuropathy was not described in these cases.

Clinical Reasoning: A 40-Year-Old Woman Presenting With Encephalopathy and Paraparesis.

Patients with acute to subacute multifocal neurologic abnormalities often have a unique presentation, and their diagnosis and management can be challenging. We present the case of a 40-year-old patient who presented with a 4-day history of confusion, bradyphrenia, right facial droop, bilateral lower limb weakness, urinary incontinence, and hypothermia. This case highlights the diagnostic approach to patients with subacute multifocal neurologic abnormalities, the importance of considering coexisting systemic illnesses in the diagnosis, and their management.

Kuwait's marine biodiversity: Qualitative assessment of indicator habitats and species.

The tropical waters of the Northern Arabian Gulf have a long history of maritime resource richness. High levels of biodiversity result from the complex matrix of coastal habitats, coral reefs and sea grass beds that characterise the region. Insight into the ongoing health of such habitats and the broader Kuwait maritime environment can be gauged by the status of indicator species found within these habitats.

Isolation and characterisation of nasoseptal cartilage stem/progenitor cells and their role in the chondrogenic niche.

Background: Since cartilage-derived stem/progenitor cells (CSPCs) were first identified in articular cartilage using differential adhesion to fibronectin, their self-renewal capacity and niche-specific lineage preference for chondrogenesis have propelled their application for cartilage tissue engineering. In many adult tissues, stem/progenitor cells are recognised to be involved in tissue homeostasis. However, the role of nasoseptal CSPCs has not yet been elucidated.
