Background: /aims. Pseudoxanthoma Elasticum (PXE, OMIM 264800) is an autosomal, recessive, metabolic disorder characterized by progressive ectopic calcification in the skin, the vasculature and Bruch's membrane. Variants in the ABCC6 gene are associated with low plasma pyrophosphate (PPi) concentration.

Background: Ectopic thyroid tissue (ETT) is a rare congenital anomaly caused by the abnormal embryonic migration of thyroid tissue, leading to its presence outside its usual pretracheal location. This condition can lead to diagnostic challenges, especially when located within the airway, as it mimics other respiratory disorders such as asthma.
Case Presentation: We report the case of a 69-year-old man with endotracheal ETT presenting with severe dyspnea, and the lesion was initially suspected to be malignant.

Oxygen consumption by oceanic microbes can predict respiration (CO production) but requires an assumed respiratory quotient (RQ; ΔO/ΔCO). Measured apparent RQs (ARQs) can be impacted by various processes, including nitrification and changes in dissolved organic matter (DOM) composition, leading to discrepancies between ARQ and actual RQ. In DOM remineralization experiments conducted in the eastern North Atlantic Ocean, ARQs averaged 1.

This review explores the genetic basis of Tourette syndrome (TS), a complex neuropsychiatric disorder characterized by motor and vocal tics. Family, twin, and molecular genetic studies provide strong evidence for a genetic component in TS, with heritability estimates ranging from 50% to 80%. The genetic architecture of TS is complex, involving both common variants with small effects and rare variants with larger effects.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome and haemophagocytic lymphohistiocytosis (HLH) are rare but severe immune-mediated diseases with overlapping clinical manifestations. We present a case of a woman in her late 40s with rheumatoid arthritis who developed DRESS/HLH overlap syndrome after starting hydroxychloroquine and leflunomide therapy. Despite corticosteroid treatment, her condition worsened, necessitating etoposide therapy.
