Actinic keratosis (AK) is a common skin condition characterized by rough, scaly patches or small growths on the skin’s surface, typically caused by long-term exposure to ultraviolet (UV) radiation from the sun or tanning beds. These patches can be precancerous and may develop into squamous cell carcinoma if left untreated.
Achalasia, also known as cardiospasm, is a rare disorder of the esophagus characterized by the inability of the lower esophageal sphincter to relax properly, leading to difficulty swallowing, regurgitation of food, and chest pain. This condition occurs due to the degeneration of nerve cells in the esophagus, causing a disruption in the coordinated muscle contractions
Achilles tendinitis is an overuse injury of the Achilles tendon, the band of tissue that connects calf muscles at the back of the lower leg to your heel bone. It is characterized by inflammation, pain, and swelling in the tendon, often caused by repetitive stress or strain on the tendon.
The Achilles tendon is a strong, fibrous tissue that connects the calf muscles to the heel bone (calcaneus). It is the largest and strongest tendon in the human body, enabling walking, running, and jumping by transmitting force from the calf muscles to the foot.
Achilles tendon injuries are damages to the fibrous tissue that connects the calf muscles to the heel bone. These injuries can range from mild tendonitis to severe ruptures and can result from overuse, sudden increases in physical activity, or direct trauma.
Achilles tendon repair is a surgical procedure performed to repair a ruptured or torn Achilles tendon, which is the strong fibrous cord that connects the calf muscles to the heel bone. The surgery aims to reattach the torn ends of the tendon and restore its function.
Achilles tendon rupture is a condition in which the Achilles tendon, the strong fibrous cord that connects the calf muscles to the heel bone, partially or completely tears. This can result from sudden forceful movements, overuse, or degeneration of the tendon. It often causes severe pain, swelling, and difficulty walking.
Achondroplasia dwarfism (ACH) is a genetic disorder characterized by short stature and disproportionately short limbs due to abnormal bone growth. It is the most common form of short-limbed dwarfism and results from a mutation in the FGFR3 gene, which affects the development of cartilage and its conversion to bone.
Acid-base disorders are a group of conditions characterized by an imbalance in the body’s acid-base balance, which can result from kidney or lung dysfunction, metabolic issues, or ingestion of a toxin like methanol or ethylene glycol. These imbalances can lead to either acidosis (excess acid) or alkalosis (excess base) in the body.
Acinic cell carcinoma is a rare type of cancer that originates in the acinar cells of the salivary glands. These cells produce saliva and are found in the parotid gland, submandibular gland, and sublingual gland. Acinic cell carcinoma is typically slow-growing and has a better prognosis than other salivary gland cancers.
