Arcus senilis; Other names: arcus adiposus, arcus juvenilis, arcus lipoides corneae, arcus cornealis: Arcus senilis deposits tend to start at 6 and 12 o'clock and progress until becoming completely circumferential. The thin clear section separating the arcus from the limbus is known as the clear interval of Vogt. Specialty: Ophthalmology Symptoms
List of medical symptoms. Medical symptoms refer to the manifestations or indications of a disease or condition, perceived and complained about by the patient. [1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals.
Juvenile, in this context, refers to disease onset before 16 years of age, while idiopathic refers to a condition with no defined cause, and arthritis is inflammation within the joint. [4] JIA is an autoimmune, noninfective, inflammatory joint disease, the cause of which remains poorly understood. It is characterised by chronic joint inflammation.
The diagnosis does not require any routine imaging or additional testing, though other causes of rectal pain must be excluded. Suspected levator ani syndrome is confirmed in the presence of chronic or recurrent rectal pain, occurring in episodes that last at least 30 minutes, with tenderness with posterior traction of the puborectalis muscle.
Osteochondritis is a painful type of osteochondrosis where the cartilage or bone in a joint is inflamed. [1]It often refers to osteochondritis dissecans (OCD). The term dissecans refers to the "creation of a flap of cartilage that further dissects away from its underlying subchondral attachments (dissecans)".
Most patients are asymptomatic, and come to clinical attention when a mass is discovered incidentally on routine dental X-rays. [2] When patients are symptomatic, they present with non-specific symptoms, such as chronic sinusitis, rhinorrhea, obstruction, pain, facial enlargement and possibly visual changes.
They propose that aged basal cells contain lipofuscin bodies that cannot be removed and might promote the aging of neighboring cells, generating a feedback loop that causes more and more neighbor cells to become aged and contain lipofuscins. [13] Such cells might then aggregate into a spot with an irregular shape. [13]
Defects in the PAX6 gene cause aniridia-like ocular defects in mice (as well as Drosophila). Aniridia is a heterozygous disorder, meaning that only one of the two chromosome 11 copies is affected. When both copies are altered ( homozygous condition), the result is a uniformly fatal condition with near complete failure of entire eye formation.
