Bronchial atresia is a rare congenital disease characterized by segmental or lobar emphysema and, in some cases, mucoid impaction. The exact cause of bronchial atresia is unknown; the lobar bronchi, subsegmental bronchi, and distal bronchioles develop in the fifth, sixth, and sixteenth weeks of fetal development, respectively.
The surgical option is cosmetic reconstruction of the external ear's normal shape and repair of the ear canal. In less severe cases, the reconstruction will be sufficient to restore hearing. In grades of anotia/microtia that affect the middle ear, the surgery with the use of a bone-anchored hearing aid (BAHA) will likely restore the hearing ...

Galagos are currently grouped into six genera. Euoticus is a basal sister taxon to all the other galagids. [4] The 'dwarf' galagids recently grouped under the genus Galagoides have been found, based on genetic data, and supported by analysis of vocalisations and morphology, to actually consist of two clades, which are not sister taxa, in eastern and western/central Africa (separated by the ...
Choanal atresia is diagnosed based on the inability to place a nasal catheter, and radiology results (particularly CT scans). Treatment involves maintaining an open airway, and may involve surgery to reopen the airway, potentially with a stent. Choanal atresia is a fairly rare condition, affecting between 1 in 7,000 to 1 in 5,000 live births.
