Congenital adrenal hyperplasia (CAH) is a dysfunction that impacts the adrenal gland’s means to launch hormones that regulate the physique’s response to emphasize and sickness. CAH is treatable, however may be probably life-threatening throughout sickness or if not managed. The dysfunction is tough to establish, and far nonetheless must be understood in regards to the situation. However new analysis carried out at Youngsters’s Hospital Los Angeles has proven that computer systems could possibly use refined facial options to acknowledge CAH. This discovering may result in higher identification of the dysfunction and higher care of CAH sufferers.
In endocrinology, CAH is among the few emergency circumstances we encounter. It is the main explanation for adrenal insufficiency in youngsters, which suggests the physique cannot produce aldosterone, adrenaline and cortisol.”

These hormones enable the physique to handle blood stress and reply to crises. As well as, CAH is marked by increased ranges of the intercourse hormone testosterone. This will result in adjustments in genitalia for feminine sufferers. However testosterone has one other impact indirectly linked to intercourse or gender–an impact that could possibly be used to assist establish CAH.
“It is fairly nicely accepted that hormones like testosterone assist to form facial options,” says Dr. Kim. “Since CAH causes excessive testosterone throughout improvement, it stands to cause that variations, even refined ones, could possibly be current in CAH sufferers.” This, she says, led her to wonder if facial morphology–a assortment of bodily traits–could help clinicians in figuring out sufferers with CAH.
“There was no established hyperlink but between CAH and facial morphology,” says Dr. Kim. This could possibly be as a result of facial variations are sufficiently subtle to be missed by most clinicians. “However advances in machine studying have come a great distance,” she says, “particularly in facial recognition.”
Dr. Kim teamed up with engineers and scientists from the College of Southern California Data Sciences Institute to design and check her speculation. The staff loaded photographs of 102 sufferers with CAH and 144 management people into computer systems that had been skilled in facial recognition. By way of machine studying, the computer systems had been in a position to establish refined variations in facial morphology and appropriately establish the sufferers with CAH with better than 90% accuracy.
The examine represents an essential step within the path to raised figuring out and understanding CAH. The findings set up, for the primary time, that not solely is there a hyperlink between facial morphology and CAH, however computer systems can detect this hyperlink and predict CAH primarily based on facial options of sufferers.
Though newborns are routinely screened for CAH, genetic assessments are costly and tough to acquire, and it is not easy to characterize severity of the situation. “We actually want a extra delicate, simpler approach,” says Dr. Kim. “It is my hope that that is it; that we will use one of the best that expertise has to supply to raised perceive CAH and assist our sufferers.”
The examine was printed within the scientific journal JAMA Community Open. Co-first authors on the examine had been Wael AbdAlmageed and Hengameh Mirzaalian from USC Data Sciences Institute.
