The etiology of microtia in children remains uncertain but there are some cases that associate the cause of microtia with genetic defects in multiple or single genes, altitude, and gestational diabetes. [3] Risk factors gathered from studies include infants born underweight, male sex, women gravidity and parity, and medication use while pregnant.
The isolated cause, a cause not associated with a syndrome, of anotia or microtia is not known, though it is believed to be of genetic basis. Developmentally, anotia/microtia occurs when certain tissues associated with the auricle do not develop. This rare defect may occur as part of a syndrome or as an isolated abnormality.
Duodenal atresia is the congenital absence or complete closure of a portion of the lumen of the duodenum. It causes increased levels of amniotic fluid during pregnancy ( polyhydramnios ) and intestinal obstruction in newborn babies.
Esophageal atresia with or without tracheoesophageal fistula (TEF) is the most common birth defect of the esophagus. The diagnosis of EA usually occurs within the first 24 hours of life, but it can be made antenatally or later. [8] Although environmental effects and genetic factors have been documented, the causes of EA remain largely unknown. [9]
Atresia, microtia, otitis media and other outer/middle ear abnormalities, as well as infants with sensorineural hearing loss, will require the use of bone-conduction ABR testing. Infants who have a considerable amount of amniotic fluid in their middle ear space may need to be tested with BCABR.

Across a wide scope of studies, scientific data does not support the health claims associated with using ginseng. [10] Short-term use of ginseng (under 3 months) is unlikely to produce side effects and appears safe for most people. Side effects, often associated with longer term use, can include headaches, insomnia, and gastrointestinal problems.
Typically, dementia is associated with classic symptoms like confusion and memory loss. But new research finds that there could be a less obvious risk factor out there: your cholesterol levels ...
