Weight loss resulting from the evaporation of water through the skin and the exhalation of water vapor.
A condition, more prevalent in boys than girls, often seen in young individuals where the growth center in the femur head becomes necrotic, eventually getting replaced by new bone. Likely caused by a vascular disorder, possibly from an injury that interrupts blood supply, leading to tissue death. It typically manifests between ages four to sixteen, peaking between four to nine. Initial symptoms include limping, with pain being occasional but not dominant. Physical examination may reveal muscle spasms and restricted hip movement, which improve with rest but can recur upon weight-bearing. Treatment emphasizes joint rest, often using a surgical appliance, rather than strict bed rest. X-rays are used to monitor bone health. The severity varies; some fully recover while others may develop significant bone deformity and later osteoarthritis in the hip. It’s also known as Legg-Calve-Perthes’ disease, pseudocoxalgia, coxa plana, osteochondritis deformans juvenilis, or quiet hip disease.
