  • Cushing's Syndrome is a disease caused by an excess of cortisol production or by excessive use of cortisol or other similar steroid (glucocorticoid) hormones. Cortisol is a normal hormone produced in the outer portion, or cortex, of the adrenal glands, located above each kidney. The normal function of cortisol is to help the body respond to stress and change. It mobilizes nutrients, modifies the body's response to inflammation, stimulates the liver to raise the blood sugar, and it helps control the amount of water in the body.

  • Two histone H4 mRNA variants, H4-v.1 and histogranin mRNAs, were detected in the rat genome and measured in various tissues and isolated alveolar macrophages. Medium to high levels of both mRNAs were present in the liver, adrenal glands, thymus, bone marrow and alveolar macrophag-es. H4-v.1 cDNA contained an open reading frame that coded for unmodi-fied whole histone H4, whereas histogranin cDNA lacked the first ATG codon and contained an open reading frame that coded for modified (Thr89) H4-(84–102). ...

  • Hormonal Evaluation Androgens are secreted by the ovaries and adrenal glands in response to their respective tropic hormones, luteinizing hormone (LH) and adrenocorticotropic hormone (ACTH). The principal circulating steroids involved in the etiology of hirsutism are testosterone, androstenedione, and dehydroepiandrosterone (DHEA) and its sulfated form (DHEAS). The ovaries and adrenal glands normally contribute about equally to testosterone production.

  • Most patients with trichotillomania, pressure-induced alopecia. The most common causes of nonscarring alopecia include telogen effluvium, androgenetic alopecia, alopecia areata, tinea capitis, and some cases of traumatic alopecia (Table 54-5). In women with androgenetic alopecia, an elevation in circulating levels of androgens may be seen as a result of ovarian or adrenal gland dysfunction. When there are signs of virilization, such as a deepened voice and enlarged clitoris, the possibility of an ovarian or adrenal gland tumor should be considered.

  • Some adenomas produce too much adrenal steroid hormones. Sometimes the excess hormone can cause symptoms. Many of the hormone-related symptoms of adenomas are the same as those from adrenal carcinomas (cancers). These symptoms are discussed in the sections, “Can adrenal cancer be found early?” and “How is adrenal cancer diagnosed?” Adenomas are much more likely than carcinomas to produce high levels of aldosterone, which can cause high blood pressure. Treatment: Adenomas can be cured by removing the adrenal gland that contains the adenoma.

  • Adrenal carcinomas are very rare and the real number diagnosed in the United States is not known. It is probably around 300 per year. They are much less common than adrenal adenomas, which are found frequently among middle aged and elderly people. Adrenal tumors (most of which are adenomas) are found in about one in every 10 people who have an imaging test (like a CT or MRI) of the adrenal gland. The average age of patients with adrenal cancer is around 45 to 50, but adrenal cortical cancer can occur in people of any age; even in children....

  • A risk factor is anything that changes a person's chance of getting a disease such as cancer. Different cancers have different risk factors. For example, unprotected exposure to strong sunlight is a risk factor for skin cancer and smoking is a risk factor for cancers of the lungs, mouth, larynx, esophagus, bladder, and several other organs. Scientists have found few risk factors that make a person more likely to develop adrenal gland tumors. Even if a patient does have one or more risk factors for adrenal gland tumors, it is impossible to know for sure how much that risk factor...

  • Scientists do not know exactly what causes most adrenal cortical tumors. Over the past few years, they have made great progress in understanding how certain changes in a person's DNA can cause cells in the adrenal gland to become cancerous. DNA is the molecule that carries the instructions for nearly everything our cells do. We usually look like our parents because they are the source of our DNA. However, DNA affects more than the way we look. It also determines our risk for developing certain diseases, including some types of cancer.

  • The need for a book such as this one has arisen as a result of recent changes in legislation and expansion in the numbers of health care professionals involved in administration and/or prescription of medicines. The book is an introduction to pharmacology for health care professionals. Although anyone involved in the care of patients is a health care professional, this book has been specifically written for physiotherapists, podiatrists and radiographers (otherwise known as allied health professionals). However, the book may be of interest to other health care professionals....

  • Renal Cell Carcinoma: Treatment Localized Tumors The standard management for stage I or II tumors and selected cases of stage III disease is radical nephrectomy. This procedure involves en bloc removal of Gerota's fascia and its contents, including the kidney, the ipsilateral adrenal gland, and adjacent hilar lymph nodes. The role of a regional lymphadenectomy is controversial. Extension into the renal vein or inferior vena cava (stage III disease) does not preclude resection even if cardiopulmonary bypass is required.

  • The type of cancer that develops in the cortex of the adrenal gland is called adrenal cortical carcinoma. It is also known as adrenocortical cancer (or carcinoma) or just adrenal cancer. In this document, the term adrenal cancer is used to mean cancer that starts in the adrenal cortex. Adrenal cancer most often is discovered for 1 of 2 reasons. The first is that it produces hormones that cause body changes such as weight gain and fluid retention, early puberty in children, or excess facial or body hair growth in women. The second reason an adrenal cancer may be...

  • Most cancers found in the adrenal gland did not start there and are not adrenal cancers. Instead, they start in other organs or tissues and then spread (metastasize) through the bloodstream to the adrenal glands. For example, lung cancers, melanomas, and breast cancers often spread to the adrenals. Even when other cancers spread to the adrenals; however, they are still named after the place they started and are treated like other cancers that start in the same place. They are not considered adrenal cancer. Their treatment is described in our documents on these cancers. ...

  • People with MEN1 have a very high risk of developing tumors of 3 glands: the pituitary, parathyroid, and pancreas. About one-third to one-half of people with this condition also develop adrenal adenomas or enlarged adrenal glands. These usually do not cause any symptoms. This syndrome is caused by defects in a gene called MEN1. People who have a family history of MEN1 or pituitary, parathyroid, pancreas, or adrenal cancers should ask their doctor if they might benefit from genetic counseling.
