AI Article Synopsis
- Hunter syndrome is an X-linked disorder caused by a deficiency in iduronate-2-sulfatase, which has recently been linked to embolic strokes.
- A case study of a 23-year-old Japanese man with this condition revealed he experienced a subcortical infarction resembling branch atheromatous disease, despite being on treatment.
- Findings included thickening of the middle cerebral artery and impaired vasodilation, indicating potential complications in the cerebral arteries related to the disease, highlighting the need to explore the mechanisms behind cerebral infarction in Hunter syndrome patients.
Article Abstract
Introduction: Hunter syndrome (mucopolysaccharidosis type II, MPS II) is an X-linked lysosomal storage disease caused by deficiency of iduronate-2-sulfatase. Recently, stroke caused by embolization with Hunter syndrome has been reported. Here, we report the case of a 23-year-old Japanese man with Hunter syndrome who developed subcortical infarction by the mechanism similar to branch atheromatous disease (BAD).
Case Presentation: He had been treated with idursulfase supplementation. He presented with left-sided weakness and conjugate eye deviation to the right, and was diagnosed with branch atheromatous disease affecting the right corona radiata, based on MRI findings. The patient was treated with argatroban and aspirin. Magnetic resonance angiography demonstrated no evidence of luminal narrowing of the cerebral arteries. T1-sampling perfection with application-optimized contrasts by using different flip angle evolutions (SPACE) imaging revealed thickened middle cerebral artery. The patient had markedly low flow-mediated vasodilation, suggesting impaired vasodilation in response to nitric monoxide.
Conclusion: The arterial wall thickening and impaired vasodilation in the cerebral arteries related to subcortical infarction. We should clarify the mechanism of cerebral infarction in Hunter syndrome patients.

Background: Mucopolysaccharidosis (MPS) type 1 S and type 2 are rare lysosomal storage disorders characterized by impaired enzyme production, resulting in glycosaminoglycans accumulation within lysosomes. Enzyme Replacement Therapy (ERT) with laronidase and idursulfase are first line treatments, respectively. However, infusion-related hypersensitivity reactions (HR) may lead to ERT discontinuation.

Importance: Short sleep duration during pregnancy and the perimenopausal period has been associated with adverse cardiometabolic outcomes. However, it remains unclear how sleep duration changes after delivery and whether such changes are associated with the cardiometabolic health of birthing people.
Objective: To investigate whether persistently short sleep during pregnancy and after delivery is associated with incident hypertension and metabolic syndrome.

Background: Rotational vertebral artery occlusion, or bow hunter's syndrome (BHS), is a rare but clinically important cause of vertebrobasilar insufficiency. Extrinsic compression of the artery is usually caused by osteophytes, fibrous bands, or lateral disc herniation and typically occurs in the setting of anatomical variations, leading to dynamic compromise of the posterior circulation. Neoplastic causes of BHS are rare.

Dysfunction of the centrosome, the major microtubule-organizing center of the cell, is implicated in microcephaly. Haploinsufficiency of mixed-lineage leukemia (MLL/KMT2A) protein causes Wiedemann-Steiner syndrome (WSS), a neurodevelopmental disorder associated with microcephaly. However, whether MLL has a function at the centrosome is not clear.

Introduction: We compared the 12-months effects of arthroscopic surgery and physiotherapist-led care for femoroacetabular impingement (FAI) syndrome on the time-varying magnitude of hip contact force and muscle contributions to hip contact force during walking.
Methods: Secondary analysis was performed on thirty-seven individuals with FAI syndrome who received biomechanical assessment before and 12-months following either arthroscopic surgery (n = 17) or physiotherapist-led care (Personalised Hip Therapy, PHT) (n = 20). At both time points, three-dimensional whole-body motions, ground reaction forces, and surface electromyograms (n = 14) were acquired during overground walking.
