Knee MRI scans are crucial for diagnosing cartilage damage, a common issue that can lead to conditions like osteoarthritis and meniscus tears. Osteoarthritis involves cartilage degeneration, causing defects and bone marrow edema. Meniscus tears affect the knee’s shock absorbers, leading to osteoarthritis and cartilage defects. Cartilage defects can impact knee function and may be related…

ECG abnormalities associated with hypercalcemia include a shortened QT interval (increased risk of arrhythmias), prolonged PR interval (delayed conduction between atria and ventricles), elevated ST segment (reduced blood flow to the heart), and T-wave inversion (reduced potassium levels). These changes indicate cardiac dysfunction and can provide clues for diagnosis and management. Shortened QT Interval Definition:…

Lichen planus on eyelids is an autoimmune condition affecting the skin of the eyelids. It manifests as violaceous papules, plaques, and erosions, accompanied by itching, burning, and irritation. Histologically, it exhibits hyperkeratosis, acanthosis, and basal cell degeneration, with a band-like infiltrate of lymphocytes at the dermoepidermal junction. Management involves topical steroids, calcineurin inhibitors, and phototherapy,…
