AbstractA right-handed woman in her 80s was admitted to the emergency department 1 h after sudden-onset global aphasia and right-sided hemiparesis. Medical history included arterial hypertension, dyslipidemia, hyperuricemia, aortic stenosis, osteoporosis, and recent pulmonary embolism. Medication consisted of apixaban, bisoprolol, hydrochlorothiazide, allopurinol, fenofibrate, and vitamin D. Vital parameters (blood pressure, heart rate, body temperature, oxygen saturation) and glycemia were all within normal range. Electrocardiogram showed a first-degree atrioventricular block.

Inflammation-mediated vitamin K and vitamin D effects on vascular calcifications in people with HIV on active antiretroviral therapy
Background: People with HIV (PWH) experience increased systemic inflammation and monocyte activation, leading to increased risk of cardiovascular events (death, stroke, and myocardial infarction) and higher coronary artery calcium scores (CACs). Vitamins D and K2 have significant anti-inflammatory effects; in addition, vitamin K2 is involved in preventing vascular calcifications in the general population. The roles of vitamins D and K in increased coronary calcifications in successfully treated PWH is less understood. Methods: We prospectively recruited 237 PWH on antiretroviral treatment (ART) and 67 healthy co...

Intracranial Calcification Due to Hypoparathyroidism
A 70-year-old Japanese man with a history of idiopathic hypoparathyroidism presented to the Emergency Department of our hospital owing to weakness in his right leg. Although his primary care doctor had prescribed activated vitamin D analogues, his serum calcium level was slightly low at 8.0  mg/dL. Owing to suspicions of stroke, he underwent radiographic imaging of the head. Computed tomography revealed bilateral and symmetrical calcifications in the basal ganglia, cerebellum, and at the gray-white junction in the axial image and the sagittal image (Figure).
