Extract of sample "Endocrine Disorder Acromegaly"

Answer 1This article mainly discusses the endocrine system, which unconsciously carries out wide range of processes through chemical messengers called "hormones." Metabolism, tissue function, moods and growth development is mainly regulated by these hormones. This signaling system utilizes blood vessels, which release glands directly into the blood stream, and then they are moved throughout the body. Alexander, Fawcett and Runciman (2006. p.162) states that, "Disorders of the endocrine system may be categorized most simply as those involving over production (hyper-secretion) and those involving under production (hypo-secretion). The hyper/hypo secretion of hormones effect and disturbs the whole balance of the system. (Alexander, Fawcett and Runciman, 2006. p.162) Acromegaly arises in a human body, when pituitary gland continuously hyper secretes the growth hormone, causing the hormonal disturbance. Endocrine and Metabolic Diseases (2008) writes that, "Excess growth hormone stimulates hepatic secretion of insulin-like growth factor-I (IGF-I), which causes most of the clinical manifestations of acromegaly."
Answer 2: The physiology and anatomy of the endocrine system in acromegaly includes that of the growth hormone while of the nervous system includes that of the pituitary gland. Growth hormone is a protein which most commonly contains 191 amino acid residues and has two main forms known as 20 K and 22 K. It is secreted in a pulsatile fashion from the anterior pituitary gland and is fundamental for its physiological effect (Varela-Nieto & Chowen, 2005).

Pituitary gland is a pea-sized gland attached to the hypothalamus by a stalk and located at the base of the brain (Alexander, Fawcett, & Runciman, 2006). One of the main functions of this gland is to regulate the levels of GH and IGF-1 in the blood and also homeostasis in the body. Some of its functions include regulation of blood pressure, thyroid gland function, metabolism and secretion of ADH among others.
Answer 3:Successful treatment of acromegaly not only reduces the levels of GH and IGF-1 to normal but also alleviates the pressure from the growing pituitary hormone exerts on the areas of the brain. Dopamine analogues such as bromocriptine does the latter but, somatostatin analogues like octreotide and lanreotide does both (Hansen, 2006). Other treatments include surgery and radiotherapy for reducing the size of the tumor (Une, 2007). Combining dopamine analogues with somastostatin analogues produces more effective results than either does alone. The somatostatin analogues effect on glucose homeostasis is minor and this increase was controlled by administrating octreotide.
Answer 4: The Endo's products continue to contribute significantly to future growth of pharmaceutical industry. Present research is investigating the safety and effectiveness of this new drug along with its dosage, schedule and combinations of somatostatin analogs and GH receptors. The suggestions for the patients of acromegaly in this are that it is safe for the patient to use this new drug because it is working well with the earlier first medication groups of SSAs and Dopamine agonists. Bankhead, C. (2009) quotes Catherine Lesage, who writes that, "The activity we observed suggests this compound should be effective in normalizing the hormonal profiles of patients with acromegaly."
The future use of this drug will take an account of the presently carried out research which insists that there is a good interaction between these drugs. Dr. Lesage was quoted in the article who writes that. "Targeting both receptors might be more effective than focusing on one." The observations and research also "provided a rationale for development of BIM 23A760, a chimeric compound that contains structural elements of somatostatin analogs and dopamine agonists." (Bankhead, C. 2009).

...? Endocrine Disorders Endocrine Disorders Hormonal system plays a vital role in performing bodily functions. Hormones are chemical agents which help in different bodily reactions. Hormones are secreted by glands in our body. Thyroid is one of the most important gland in our body which produces two main hormones known as thyroxine and triiodothyronine, store them and then secrete them whenever they are needed in the body. The main function of these hormones is to control the metabolic rate of the body. The production and secretion of these hormones from thyroid gland are regulated by another hormone thyroid stimulating hormone (TSH) which is released from the anterior lobe of the pituitary gland. In some diseases abnormalities occur...

The findings were taken from using magnetic resonance imaging to scan the brain of subjects who smoke for more than five joints a day in a minimum of ten years and compared them with non-substance takers (Stacey 1997, p. 62-63). Regular cannabis smokers had a 12 % smaller hippocampus and a 7% smaller amygdala. The hippocampus is involved with emotion and memory, while the amygdala regulates fear and aggression. Cannabis users are also reported to tend to fare worse in tests of verbal memory and a likewise likelihood for a low-level symptoms of psychotic disorders such as schizophrenia.

Endocrine Disruptors

...Endocrine Disruptors The harmful effects of exposure to environmental pollutants on reproduction and development in wildlife populations have been acknowledged and reported in the scientific literature for many years. Some reported reproductive disorders in wildlife have included morphologic abnormalities, eggshell thinning, population declines, impaired viability of offspring, altered hormone concentrations and changes in socio-sexual behaviour. However, what has been elusive is how these chemicals exert their influence on the reproductive and developmental process of wildlife animals (CLS, 1999; Colborn, 1999). However, recent studies have shown that the reproductive and developmental anomalies caused by these chemical are induced...

It consists of the endocrine glands, hormones and receptors in the target cells. The major endocrine glands are the pituitary gland, the pineal gland, the thyroid gland, the parathyroid gland, the adrenal gland, the pancreas, the gonads (ovaries and testes), the thymus and the hypothalamus. Hormones are chemical messenger secreted by the endocrine glands. Hormones target receptors in particular cells or organs and effect changes in cell activity.

This greatly increased sensitivity to cortisol means that its negative feedback effects on the HPA axis are magnified (Jaffee et al.) It is also possible that the hypoactivity often seen with PTSD, chronic pain, chronic fatigue, and other chronic stress states is not related to the stress disorders at all, but is due to a co-morbidity with major depressive disorder (Yehuda et al.). This hypothesis is reasonable due to the fact that life with a chronic stress disorder is often very difficult for the patient, and being unable to successfully live a normal life could easily result in major depression.

Curing Attention Deficit Disorder

Media Article: In “Curing Nature Deficit Disorder”, Patrick Tucker investigates the claim made by Richard Louv in his book “Last Child in the Woods” to the effect that when a child is deprived of adequate "nature exposure", i.e., support, care, attentive parenting and social interaction, his/her physical and mental health will be negatively impacted. This can result in, diminished sensory perception, attention deficit and higher rates of physical and emotional illness. Louv further argues that getting back to nature may help children cope with ADHD. He supports his argument by citing several studies that provide strong evidence that outdoor activities alleviate two ADHD symptoms: inattentiveness and fluctua...

As the process of urbanization takes off and more people start residing in major cities, the fissures start to appear within the apparent harmonious co-existence. There are several reasons why disorderly conduct on part of individuals and groups takes place. Sociologists have proposed numerous theories explaining this phenomenon.

Attention Deficit Hyperactivity Disorder

There has also been a long debate and research over the question that whether parents should medicate a child with ADHD. Many doctors and analysts say that medication is the best solution for such children; others say medication should simply not be used on children so young, and some say that medication should never be used alone or as a substitute for other treatments.
The current treatments that are available for ADHD are for reducing the symptoms and improving functioning. There are no specific treatments that could completely cure the disorder. This is because there are primarily no biological tests that would show that a child is suffering from AHDH, these are merely symptoms that would help in the diagnosis (Passmore 1...
