study of endocrine-related conditions and physiology

Conditions: Endocrine Disease

Summary: background: endocrine disorders involve changes to glands that produce hormones. hormones are released by these glands into the blood so they can direct the function of other tissues in the body. researchers want to study people who may have endocrine disorders. they want to learn more about the conditions that affect endocrine glands. objective: to study adults with a variety of endocrine disorders for research and physician education. eligibility: adults ages 18 and older who have an endocrine or metabolic-related disorder healthy volunteers 18 and older design: participants will be screened with a review of their medical records. participants will have a physical exam and medical history. the length of the study and the schedule will vary by participant. tests may include: blood and urine tests stool and saliva samples imaging studies: participants will lie on a table while a machine takes pictures of the body. they may be injected with a substance to make their organs more visible in the pictures. tests of endocrine tissue function consultation with other specialists sleep study medical photographs participants may be treated for their endocrine disorder. this could include: surgery. if tissue is removed during surgery, it may be studied. radiation medicine participants may have genetic testing. this will be done with a small amount of blood, cells from a cheek swab, or saliva. sponsoring institution: national institute of digestive, diabetes and kidney disease

this protocol is designed to allow inpatient and outpatient evaluation of adults with a variety of endocrine disorders for purposes of research and physician education in our accredited internal medicine endocrinology training programs. participants will receive clinical care per standard of practice for their condition. data collected from standard clinical practice will be retained for future research. the research-directed evaluations may include collection and retention for future use of blood, feces, saliva, or urine samples or evaluation of tissue that was routinely collected for clinical care. in some patients with endocrine disorders, laboratory or radiological studies will be performed to confirm a diagnosis or to aid in the management of the patient, using standard approaches in current clinical practice. in some cases, the patient will receive medical, radiation or surgical treatment for their disorder.

Eligibility criteria:
* inclusion criteria: * age 18 years or greater. * the possible disorder of the patient subjects must complement the case-mix in the ietp, as determined by the principal investigator. a log will be used to assure that the training needs of the teaching protocols are being met. exclusion critieria: 1. unstable patients and patients with severe organ failure, or those with a condition or medical treatment that may affect/limit the endocrine work-up and exhaust clinical center, ietp resources will be excluded if appropriate. decisions will be made on a case by case basis by the investigators. for example, there is a weight limit for the interventional radiology table used for venous sampling. 2. inability of a subject to adhere to a proposed schedule of visits. 3. individuals must be able to provide informed consent.
