Researchers will take samples of blood, urine, saliva, and stool from healthy children ages 5-17 in order to study different aspects of hormones.\n\nEstablishing a range of normal hormone levels in children will make diagnosing illnesses with abnormal levels of hormones much easier. Hormone levels in the body can change throughout the day. By collecting samples at different times researchers hope to learn more about the normal daytime and nighttime patterns of hormone secretion. Because some hormone levels change with body size, researchers will also take measurements of patient's body composition.\n\nThis study will involve children and observe them as inpatients or as outpatients. \\<TAB\\>", "detailedDescription"=>"We wish to obtain blood, urine, saliva, and stool specimens from healthy children ages 2-18 years for use in establishing the normal ranges of levels of hormones and the variations in genes that are important for hormones to act. Such hormone values are extremely important to allow endocrinologists to determine when hormone levels are truly abnormal in children suspected of an illness. Because the values of some hormones change with body size, we will obtain measurements of body composition when studying such hormones. Children participating in this study may be studied in the outpatient clinic (at most 2 blood draws) or as inpatients on the pediatric ward (for frequent blood sampling using an intravenous line over a 24-hour period). Other studies that may be performed as part of this study include ultrasound examinations of the thyroid, adrenal, ovaries or testes, and x-ray of the hand and wrist for bone age determination."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["CHILD", "ADULT"], "maximumAge"=>"18 years", "minimumAge"=>"2 years", "healthyVolunteers"=>false, "eligibilityCriteria"=>"* INCLUSION CRITERIA:\n\nGood general health.\n\nAge 2 to 18 years.\n\nEXCLUSION CRITERIA:\n\nVolunteers will be excluded for the following reasons:\n\nPresence of renal, hepatic, gastrointestinal, most endocrinologic (e.g., Cushing's syndrome) or pulmonary disorders (other than asthma not requiring continuous medication);\n\nIndividuals who have, or whose parent or guardians have, current substance abuse or a psychiatric disorder or other condition which, in the opinion of the investigators, would impede the ability to give informed consent or possibly hinder completion of the study;\n\nSubjects who regularly use prescription medications are not eligible.
