Atelectasis development of atelectasis include: type of surgery (thoracic, cardiopulmonary surgeries), use of muscle relaxation, obesity, high oxygen, the lower lung segments. Factors not associated with the development of atelectasis include: age, presence of COPD or asthma, and type of anesthetic. In the early 1950s, in UK aviation medicine, the condition "acceleration atelectasis" was given the name "Hunter Lung" due to its prevalence in pilots of the transonic fighter jet the Hawker Hunter, which used a 100% oxygen schedule. Clinically significant atelectasis is generally visible on chest X-ray; findings can include lung opacification and/or loss of lung volume. Post-surgical atelectasis will
Albinism in humans of melanocyte tyrosinase enzymes, a change that is hypothesized to promote brown versus black melanin synthesis, resulting in a third oculocutaneous albinism (OCA) genotype, ″OCA3″. Some rare forms are inherited from only one parent. There are other genetic mutations which are proven to be associated with albinism. All alterations, however, lead to changes in melanin production in the body. Some of these are associated with increased risk of skin cancer . The chance of offspring with albinism resulting from the pairing of an organism with albinism and one without albinism is low. However, because organisms (including humans) can be carriers
