Kyphosis most cases of kyphosis are mild and only require routine monitoring, serious cases can be debilitating. High degrees of kyphosis can cause severe pain and discomfort, breathing and digestion difficulties, cardiovascular irregularities, neurological compromise and, in the more severe cases, significantly shortened life spans. These types of high-end curves typically do not respond well to conservative treatment and almost always warrant spinal fusion surgery, which can restore the body's natural degree of curvature. Prevalence of kyphosis has been linked to nasal obstruction in a study. The risk of serious complications from spinal fusion surgery for kyphosis is estimated to be
Body louse Body louse The body louse ("Pediculus humanus humanus", sometimes called "Pediculus humanus corporis") is a louse that infests humans. The condition of being infested with head lice, body lice, or pubic lice is known as pediculosis. Body lice are vectors for the transmission of the human diseases epidemic typhus, trench fever, and relapsing fever. The body louse genome sequence analysis was published in 2010. "Pediculus humanus humanus" (the body louse) is indistinguishable in appearance from "Pediculus humanus capitis" (the head louse) but will interbreed only under laboratory conditions. In their natural state, they occupy different habitats and do not usually
