Case Report: ISG15 deficiency caused by novel variants in two families and effective treatment with Janus kinase inhibition.

ISG15 deficiency is a rare disease caused by autosomal recessive variants in the gene, which encodes the ISG15 protein. The ISG15 protein plays a dual role in both the type I and II interferon (IFN) immune pathways. Extracellularly, the ISG15 protein is essential for IFN-γ-dependent anti-mycobacterial immunity, while intracellularly, ISG15 is necessary for USP18-mediated downregulation of IFN-α/β signalling.

Combined novel homozygous variants in both and STAT presenting with severe combined immune deficiency: case report and literature review.

Background: Sphingosine phosphate lyase insufficiency syndrome (SPLIS) is associated with biallelic variants in , comprising a multisystemic disease characterized by steroid resistant nephrotic syndrome, primary adrenal insufficiency, neurological problems, skin abnormalities and immunodeficiency in described cases. Signal transducer and activator of transcription 1 (STAT1) plays an important role in orchestrating an appropriate immune response through JAK-STAT pathway. Biallelic loss of function (LOF) variants lead to STAT1 deficiency with a severe phenotype of immunodeficiency with increased frequency of infections and poor outcome if untreated.

A Carrier Female Manifesting an Unusual X-Linked Retinoschisis Phenotype Associated with the Pathogenic Variant c.266delA, p.(Tyr89LeufsTer37) in , and Skewed X-Inactivation.

X-linked retinoschisis (XLRS) is the most common juvenile macular degeneration in males. Unlike most other X-linked retinal dystrophies, carrier heterozygous females are very rarely reported to show clinical features of the disease. Herein, we describe unusual retinal features in a 2-year-old female infant with family history and genetic testing consistent with XLRS.

Inter-subject correlations during natural viewing: A filter-bank approach.

A central question in neuroscience is how the brain processes real-world sensory input. For decades most classical studies focus on carefully controlled artificial stimuli. More recently researchers started to investigate brain activity under more realistic conditions.

Feasibility of high-flow nasal oxygen therapy and two-stage sedation during endoscopic hypopharyngeal therapy.

Background: Structural disorders of the hypopharynx can lead to dysphagia-related morbidity. Endoscopic therapy in this area, for example, myotomy for Zenker's diverticulum (ZD), has traditionally been performed under general anesthesia (GA). We have developed a two-stage sedation process, which is used along with high-flow nasal oxygen therapy (HFNOT) to facilitate endoscopic hypopharyngeal procedures.
