Peripheral clock system circadian abnormalities in Cushing's disease.

abstract：:A circadian rhythm of heart rate and respiratory rate was seen at 1, 8, and 12 months of age in an infant born without ocular tissue, which supports the possibility that the time cues were nonphotic. No melatonin circadian rhythm was detected at any age up to 9 years of age, and this is most likely associated with the...
