Since barycentric coordinates are all positive for a point in a triangle's interior but at least one is negative for a point in the exterior, and two of the barycentric coordinates are zero for a vertex point, the barycentric coordinates given for the orthocenter show that the orthocenter is in an acute triangle's interior, on the right-angled ...
Modality in this example: CT: MRI: CSF spaces over the convexity near the vertex (red ellipse ) Narrowed convexity ("tight convexity") as well as medial cisterns: Widened vertex (red arrow) and medial cisterns (green arrow) Callosal angle (blue V) Acute angle: Obtuse angle: Most likely cause of leucoaraiosis (periventricular signal alterations ...

The disease was first described by Maroteaux and Lamy in 1962 [4] [5] at which time it was defined by the following characteristics: dwarfism; osteopetrosis; partial agenesis of the terminal digits of the hands and feet; cranial anomalies, such as persistence of fontanelles and failure of closure of cranial sutures; frontal and occipital bossing; and hypoplasia of the angle of the mandible.

Acute Lyme radiculopathy follows a history of outdoor activities during warmer months in likely tick habitats in the previous 1–12 weeks. [9] In the U.S., Lyme is most common in New England and Mid-Atlantic states and parts of Wisconsin and Minnesota , but it is expanding to other areas.
Gerstmann syndrome is a neurological disorder that is characterized by a constellation of symptoms [1] that suggests the presence of a lesion usually near the junction of the temporal and parietal lobes at or near the angular gyrus.
Acute coronary syndrome (ACS) is a syndrome due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. [1] The most common symptom is centrally located pressure-like chest pain , often radiating to the left shoulder [ 2 ] or angle of the jaw, and associated with nausea and ...
Thromboangiitis obliterans, also known as Buerger disease (English / ˈ b ɜːr ɡ ər /; German: [ˈbʏʁɡɐ]) or Winiwarter-Buerger disease, is a recurring progressive inflammation and thrombosis (clotting) of small and medium arteries and veins of the hands and feet.
