Endocrine System: Function, List Of Glands, Hormones, Role Of Endocrine Hormones: Puberty, Menstrual Cycle, Menopause. What Can Go Wrong With The Endocrine System? Addison's Syndrome. Cause: Hyposecretion (too little) of adrenocortical hormones (sex, growth and salt regulation hormones). Effects: Muscle waste (atrophy) and weakness; high blood pressure; gastric problems like vomiting, changes in skin pigmentation, irregular menstrual cycle and dehydration.

Amenorrhea. Cause: Linked to high levels of testosterone (in women), stress; radical weight loss and anemia. Effect: Missed periods.
Cushing's Syndrome. Cause: Excess levels of adrenocortical hormones (sex, growth and salt regulation hormones). It is the opposite of Addison's syndrome. Effects: Muscular atrophy and weakness, high blood pressure, moon- shaped face, redistribution of body fat, sometimes mental illness and osteoporosis (brittle bones). Premenstrual Syndrome (PMS)Cause: The start of menstruation - usually starts about one week before.
Effects: PMS can cause depression, bloating, irritability, swollen and tender breasts, restlessness. Polycystic Ovary Syndrome (PCOS) Cause: Still not known. Effects: The symptoms of PCOS include irregular periods, follicular ovarian cysts and sometimes infertility, enlarged ovaries and often high levels of estrogen. PCOS patients are obese and and suffer hirsutism (excess body or facial hair). Endometriosis. Cause: Endometriosis is a condition where fragments of the womb end up in other parts of the body instead of being shed during a monthly menstrual bleed.
The doctors are not sure what causes endometriosis, but it may be linked to excessive estrogen levels. Effects: Symptoms include painful periods, female infertility, frequent yeast infections and exhaustion.

I ntroduction. Lymphadenopathy is a common clinical finding with a broad differential diagnosis. Isolated enlarged lymph nodes may be found in healthy.
Ovarian Cysts. Cause: An ovarian cyst is an abnormal sac filled with fluid, rather like a blister, that forms on or inside the ovary. The cause is not yet known. Effects: Irregular or missed periods, cramps on one side of the body, spotting between periods and tender breasts. See, signs of ovarian cysts. Stress. Stress is a threat to the body and the body responds to it like any other danger - the adrenal medulla releases adrenaline and noradrenaline to help us with the fight or flight response. The physical manifestations of the arrival of adrenaline in the body are faster heart rate and breathing, sweating (hence sweaty palms when we are frightened or nervous), a glucose rush from the liver and heightened senses (like hearing and sight). Prolonged stress may cause amenorrhea in women and low production of sperm in men. Read more about the dangers of stress.
Type 1 Diabetes. Cause: Type 1 diabetes is an autoimmune disease where the pancreas cannot produce insulin. Effects: Symptoms include high levels of blood glucose, excessive thirst, peeing frequently, tiredness and weight loss. There is no cure but it can be controlled by regular (2 to 4 per day) insulin injections.
Type 2 Diabetes. Cause: With type 2 diabetes the body cells do not respond properly to insulin and the pancreas may not produce enough. Closely linked to obesity. Effects: Symptoms are as Type 1, but may not be as obvious and take longer to develop. Prediabetes is an early warning.
Type 2 diabetes can be controlled by a healthy diet and physical activity. Tablets or insulin injections may also be required. Goiters. A goiter (also spelled goitre) is an abnormally enlarged thyroid gland; can result from underproduction or overproduction of hormone or from a deficiency of iodine in the diet. Grave's Disease. Graves disease is an auto- immune disease. It most commonly affects the thyroid, causing it to grow to twice its size or more, be overactive, with related hyperthyroid symptoms such as increased heartbeat, muscle weakness, disturbed sleep and irritability. Hyperthyroidism. Hyperthyroidism (also called (thyrotoxicosis) is an overactive thyroid gland. It is a glandular disorder resulting from an overproduction of thyroid hormones.
Hypothyroidism. Hypothyroidism is an underactive thyroid gland; a glandular disorder resulting from insufficient production of thyroid. Insomnia. The inability to sleep - also referred to as chronic sleeplessness.
Acromegaly. The bones of the hands, face and feet are enlarged. It is often accompanied by muscle pain, headaches and emotional problems. It is caused by the overproduction of growth hormones in the pituitary gland due to a tumor (in adults). Gigantism. Abnormally large growth in a young person, usually caused by excessive secretion of growth hormone from the pituitary gland. Hyperparathyroidism.
High levels of parathyroid hormone are secreted which results in abnormally high levels of calcium in the blood. It can affect many systems of the body (especially causing bone resorption and osteoporosis). Hypoparathyroidism.
Not enough parathyroid hormone being secreted resulting in abnormally low levels of calcium in the blood.

The. Oncologist. com. Abstract. Lymphadenopathy is a common clinical finding and is frequently benign. Warning signs suggestive of a malignant etiology include.
A metastatic solid tumor is always in the differential diagnosis of localized lymphadenopathy, particularly. In the case of more generalized lymphadenopathy, in addition to the more common lymphomas, benign etiologies. Benign etiologies of lymphadenopathy can.
Rare but benign lymphoproliferative. Kikuchi’s disease, Rosai- Dorfman disease, and progressive transformation of germinal centers. Atypical lymphoproliferative. Castleman’s disease, lymphomatoid. Previously considered in this category but now classified as a true lymphoma is. Physicians need to be aware of all of these disorders when evaluating.
Introduction. Lymphadenopathy is a common clinical finding with a broad differential diagnosis. Isolated enlarged lymph nodes may be found. In one series of 5. Thirty- one percent of those patients had benign reactive lymphadenopathy and 2.
How, then, does one distinguish concerning from insignificant lymphadenopathy? Lymph nodes < 1 cm in size are rarely malignant. Single or localized lymph nodes may suggest a local infection, although even isolated enlarged supraclavicular, axillary. Metastatic solid tumors are often associated with localized lymphadenopathy, particularly when the lymph nodes are firm.
Generalized lymphadenopathy, however, particularly if associated with hepatosplenomegaly. B symptoms, is particularly concerning for lymphoma or a systemic disease that mimics. In this article, we review the diseases that can cause generalized lymphadenopathy and, therefore, mimic lymphoma. Table 1⇓). We specifically do not address the common malignant lymphomas and leukemias themselves, although they often present with. Instead, we focus on the clinical mimics of these lymphomas, which can be subdivided. HIV or Epstein- Barr virus (EBV); autoimmune, hypersensitivity, or other benign disorders. Kikuchi’s disease; and atypical potentially malignant lymphoproliferative.
Castleman’s disease and lymphomatoid granulomatosis. Table 1. Causes of lymphadenopathy. Infections. The range of infections that can cause significant lymphadenopathy is extensive. Acute bacterial infections, generally streptococcal. In the referral setting, in patients with persistent. EBV, and HIV [2, 5].
EBV infection is associated with a clinical spectrum of lymphoproliferative disease ranging from infectious mononucleosis. Hodgkin’s disease (HD)  and non- Hodgkin’s lymphomas (NHLs), particularly those that arise in immunodeficient patients including transplant recipients. HIV patients [7–9]. Similarly, although HIV is associated with benign lymphadenopathy, HIV disease is also highly associated with the development. NHLs, HD [1. 0], Castleman’s disease (see below), and Kaposi’s sarcoma (KS). Therefore, even if EBV or HIV disease is identified, lymph. Autoimmune Disorders.
Almost any autoimmune disorder can be associated with lymphadenopathy, but the most common associations are with rheumatoid. SLE), and Sjogren’s syndrome [1.
Lymphadenopathy may occur in as many as 7. Although. the enlarged nodes may be related to inflamed joints, generalized adenopathy can also occur, often when the disease is active. Pathology generally shows reactive lymphoid hyperplasia with interfollicular plasmacytosis [1. Lymphadenopathy in SLE is also quite common, occurring in 2. Lymph node pathology in this case generally shows a diffuse hyperplasia with scarce follicles [1.
Sjogren’s syndrome is characterized clinically by ocular and oral dryness, with lymphocytic infiltration of salivary and lacrimal. B cell activation [1. Development of a lymphoproliferative disorder may be heralded by marked enlargement of the salivary glands or worsening. Lymph node biopsies in Sjogren’s syndrome frequently show reactive adenitis or atypical lymphoid hyperplasia [1. Sjogren’s syndrome do have an estimated 4. NHL [1. 6]. These lymphomas are most commonly marginal zone lymphomas [1. Rapid enlargement of the salivary glands, with or without persistent lymphadenopathy.

Nutritional Considerations. Basal Temperature Test. Until a little more than one hundred years ago, the single controlling force for all of the complex processes that go on in the human body was thought to be the nervous system.
But there were too many phenomena that, when carefully analyzed, seemed to have no relationship to the nervous system, too many differences in people - -- in size and energy, for example - -- that could not be accounted for satisfactorily in terms of nervous activity alone. The explanation was to be found in certain glands, the endocrines, of which the thyroid is one and, in fact, one of the first to be discovered. Because commonly used tests for thyroid function are not accurate particularly when it comes to mild and even some moderate forms of hypothyroidism, and many if not most of those with low thyroid function remain undiscovered. Since the hormones of the thyroid gland regulate metabolism in every cell of the body, a deficiency of thyroid hormones can affect virtually all bodily functions.
The degree of severity of symptoms in the adult range from mild deficiency states which are not detectable with standard blood tests (subclinical hypothyroidism) to severe deficiency states which can be life- threatening (myxedema). There is an old medical saying that just a few grains of thyroid hormone can make the difference between an idiot and an Einstein. It aptly characterizes the thyroid as a quickener of the tempo of life. All of the endocrine glands play remarkable roles in the body's economy.
Unlike the many millions of other glands such as the sweat glands in the skin, the salivary glands in the mouth, the tear glands in the eyes, which perform only local functions, the endocrine glands pour their hormone secretions into the bloodstream which carries them to all parts of the body. From the pea- sized pituitary gland at the base of the brain come hormones that influence growth, sexual development, uterine contraction in childbirth, and milk release afterward. The adrenals, rising like mushrooms from atop the kidneys, pour out more than a score of hormones, including hydrocortisone and adrenaline needed for the body's response to stress and injury.
Also in the endocrine system are the sex glands - ovaries and testes; the pineal gland in the brain whose hormones play a role in nerve and brain functioning; the thymus behind the breastbone which appears to be involved in establishing the body's immunity function; and areas in the pancreas, the islets of Langerhans, which secrete insulin. A large majority of the thyroid hormone secreted from the thyroid gland is T4, but T3 is the considerably more active hormone. Although some T3 is also secreted, the bulk of the T3 is derived by deiodination of T4 in peripheral tissues, by the enzyme thyroid peroxidase especially liver and kidney. Deiodination of T4 also yields reverse T3, a molecule with no known metabolic activity. Deficiency of thyroid hormone may be due to lack of stimulation by the pituitary gland, defective hormone synthesis or impaired cellular conversion of T4 to T3 (often caused by mercury toxicity). The pituitary gland regulates thyroid activity through the secretion of thyroid- stimulating hormone (TSH).
The combination of low thyroid hormone and elevated TSH blood levels usually indicates defective thyroid hormone synthesis, which is defined as primary hypothyroidism. When TSH and thyroid hormone levels are both low, the pituitary gland is responsible for the low thyroid function, a situation termed secondary hypothyroidism. Normal blood thyroid hormone and TSH blood levels combined with low functional thyroid activity (as defined by a low basal metabolic rate) suggest cellular hypothyroidism. Most estimates on the rate of hypothyroidism are based on the levels of thyroid hormones in the blood. This may result in a large number of people with mild hypothyroidism going undetected.
Before the use of blood measurements, it was common to diagnose hypothyroidism based on basal body temperature (the temperature of the body at rest) and Achilles reflex time (reflexes are slowed in hypothyroidism). With the advent of sophisticated laboratory measurement of thyroid hormones in the blood, these "functional" tests of thyroid function fell by the wayside. However, it is known that the routine blood tests may not be sensitive enough to diagnose milder forms of hypothyroidism.
