Pheochromocytoma Essay Example for Free

Pheochromocytoma Essay Above the kidneys are two yellowish- orange colored glands that are approximately two and half by one inch called the adrenal glands. The adrenal glands play a very important role in secreting hormones and protecting the body from stress. The adrenal glands are composed of two parts, the adrenal cortex and the adrenal medulla. The adrenal cortex is the outer part of the adrenal gland that produces steroid hormones that regulate many different body functions. Not only that, but a hormone called aldosterone is produced by the adrenal cortex. This hormone regulates the amount of water and salt that is in a person’s body. The adrenal gland also has another part called the adrenal medulla which also has a significant role. The adrenal medulla’s functions mainly deal with stress and frightening situations. It produces hormones known as catecholamines such as adrenaline and noradrenaline. Catecholamines deal with responding to acute or severe, sudden stress like in situations that are life threatening. Theses catecholamine hormones are responsible for the racing of the heart, known as palpations, sweating, the shakiness of the hands, and the widening of the eyes when a stressful situation occurs or when faced with sudden fear. When these glands begin to grow tumors called Pheochromocytoma. Phechromocytoma is a rare tumor that is found on the adrenal glands that causes hyper secretion of hormones that control the heart rate, blood pressure, and metabolism called epinephrine and norepinephrine that results in intermittent or sustained hypertension. Pheochromocytoma most often occurs in young to middle- aged adults that are between the ages of 30 and 60. Out of the people who are affected, ten percent of them are children that develop symptoms between the ages of 6 and 14. Many factors contribute to the cause of phechromocytoma. Environmental and genetic factors both play a role in most cases. Pheochromocytoma can occur either alone, or in combination with other disorders. Neurofibromatosis Von Hippel-Lindau disease, tuberous sclerosis, Sturge-Weber syndrome, multiple endocrine neoplasia syndrome, also known as MEN syndrome, and ataxia-telangiectasia are the most common disorders that pheochromocytoma are associated with. Since it can combined with other conditions, there are also quite a few symptoms that go alomg with it as well. If a person has pheochromocytoma, high blood pressure is the most common symptom, which can be to the extreme at times. Although every child is different and may experience symptoms differently, other symptoms may include rapid pulse, headache, racing heart, poor weight gain despite a good appetite, vomiting, dizziness, sweating, pale skin, growth failure, nausea, clammy skin, and abdominal pain. Because pheochromocytoma may resemble other medical conditions or problems, it is always best to consult the child’s physician for a proper diagnosis. Diagnostic procedures for pheochromocytoma, along with a complete physical examination and medical history, may include a urine and blood test so that hormone levels can be measured, a CAT scan may be taken of the adrenal gland, which is more detailed than a general x- ray and a radioisotope scan. Also, genetic testing may be done as well. Once pheochromocytoma is diagnosed, treatment can begin. Based on the overall health, age, medical history, tolerance for specific medications, the extent of the disease, and ther factors, will help the physician determine the specific treatment needed for pheochromocytoma. Usually, the treatment includes removing the tumor. However, before the tumor can even be removed, the physician may prescribe some mediations to control high blood pressure. When dealing with children and pheochromocytoma, there may be multiple tumors. In this case, before the surgery, an extensive evaluation is required to locate the tumors. After surgery, to monitor the development of future tumors, on- going medical follow- ups may be necessary. Since, in most cases, genetics play a role in pheochromocytoma, family members are well- advised to be tested to rule out the presence of any tumors.

The Japanese Economy :: essays research papers fc

The Japanese Economy   Ã‚  Ã‚  Ã‚  Ã‚  The prewar economy of Japan was a Socialist economy and the country was ruled by an emperor up to WW2 and after WW2 it started to lean towards a mixed market economy until what it is today although its government is Socialist it is leaning towards a mixed market economy.   Ã‚  Ã‚  Ã‚  Ã‚  The Japanese economy is a mixed economy that leans towards market, it is like this because almost all business are run by private corporations or people and that is the market in the economy. And the reason that they are thriving and are so competitive is because of the trade tariffs and quotas that the government has in place. These regulations include heavy taxes on some products and denial on some others for example: the way Japan will only let certain foreign cars in to Japan and even then they are so heavily taxed that the average Japanese person can ¹t pay that much and will have to buy a Japanese made car and at the same time in other countries they are selling their cars for less than anyone else in that country and that is what they do with most of their products and is how they get a trade surplus year after year.   Ã‚  Ã‚  Ã‚  Ã‚  Manufacturing is the most important economic activity in Japan it accounts for about 28% of it ¹s GDP. The Japanese people import more than half of the products that they manufacture from other countries in their crudest form and manufacture them into transportation equipment, iron, steel, chemicals, petroleum and coal products and textiles. Most of these products are produced by large corporations with many employees and the happier the employees are the more it will be done.   Ã‚  Ã‚  Ã‚  Ã‚  An aspect of a market economy that Japan has is the way the companies treat their workers. The way the Japanese treat their workers is so different form the way we treat our workers here. The Japanese are so much more respectful towards their employer( the exact opposite from other countries especially those with a centralised economy) and often work for one employer until retirement. Some of the special treatment that the workers receive is housing; some of the companies namely Honda have a special housing unite for their workers and their families and a company cemetery for all the workers and their families. Because of this the employees work habits are much more productive and a larger profit can be turned and they can get a jump on the competition.   Ã‚  Ã‚  Ã‚  Ã‚  In centralised economies very few lucturies are returned to the people and in market economies most of them are, in Japan there are to kinds of people

“Emotion is stronger than reason.”To what extent is this true in Human Science Essay

People will make lots of decisions in their life, some of the decisions are emotional , and some are intellectual. From my point of view, I think emotion and reason are all important, and it’s depends on a specific situation and specific person to decide if it’s stronger or not.So my stance is neutral. If a person is very intellectual, most of his decision will be reasonable, but if he is a very emotional person, most of his decision would be emotional. For instance, smoking , which is a very emotional decision , because everyone knows cigarette is bad for our health , but some people still can not quit smoking . The reason of this is when they smoke , cigarette will bring them pleasant sensation, and those smokers will want more cigarette , in their mind , emotion is stronger than reason.However, on the other hand, there also have some people who quit smoking successfully or don’t start smoking in the first place. From their perspective, reason is stronger than emotion . Another example, Apple, a very large company in the world, the founder of it is Steve Jobs,who is also a emotional person, because his objective is to make better electronic devices for customs and have more creative ideas to make people’s life better.that might cause company run out if money , because better quality design will cause more money to produce it .But, Apple’s shareholders don’t think that way, they want to make more money, increase the profit ,lower the input and keep this company running , did not think of if the product is creative, they think more about the future of Apple , so that’s reasonable and intellectual.
