Atelectasis surgery, radiation therapy, chemotherapy, or laser therapy may prevent atelectasis from progressing and recurrent obstructive pneumonia from developing. Atelectasis Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. It may affect part or all of a lung. It is usually unilateral. It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid. It is often called a collapsed lung, although that term may also refer to pneumothorax. It is a very common finding in chest x-rays and
Body louse genome. Other lice that infest humans are the head louse and the crab louse. The claws of these three species are adapted to attachment to specific hair diameters. 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
