AORTIC STENOSIS

Friday, January 27, 2012

Most cases are due to rheumatic fever and some to syphilitic artistes. Occasional cases are due to bacterial endocarditic or trauma. Functional incompetence may be secondary to hypertension or thermo of the aorta. Surgical treatment has recently been introduced but its value is not yet established. Some cases are due to rheumatic fever, usually in association with other valvular lesions. Aortic stenosis with calcification of the valve often occurs as an isolated lesion in elderly males commonly in association with a congenital bicuspid valve. The clinical features will depend on the degree of narrowing and the presence or absence of other valvular lesion. In recent years it has been realized that mild cases of stenosis are relatively frequent but often unrecognized. In the compensated phase symptoms may be entirely absent. When left ventricular failure occurs its symptoms and signs are similar to those occurring in aortic incompetence. The degree of ventricular hypertrophy is usually greater. In addition, faintness and dizziness, syncope, angina pain, heart block and sudden death all tend to be associated. Such symptoms are probably due to myocardial or cerebral ischemia.

North Face jackets

Hi! Being in Denver I don’t think I can love winters, I abhor them to the core. They are so ruthless and since my job involves lots of travelling I have to ‘live out of suitcase’ most of the time. As you all know how excruciating it would be when you need to travel amidst blizzard. And I should say snow is my ‘Achilles heel’. Bright weather gives an optimistic feel but the gloomy winter weather makes one go ballistic. My mother used to tell me that improper clothing was the main reason for me to dislike the weather. Well she is right I hate wearing bulky clothes I’d love to wear clothes which are light but at the same time it should be warm enough. My sister Sara who came to celebrate Christmas with us gifted me two North Face jackets. One was a Chromium Thermal Jacket and the other one was The North face Men’s Atlas Triclimate Jacket. I should say they looked really cool on me but kept me very warm. Didn’t feel that I was wearing bulky jackets and for the first time I started loving the snow fall. I thanked my sister Sara for the great Christmas gift. Have a nice day guys.

Health Tips - Chlorothiazide Dose

For each gram of chlorothiazide prescribed, 2g of potassium chloride should be given and this should be taken on the days when chlorothiazide is not being given. The maximum effective dose of chlorothiazide is 2g daily by mouth and this is there poetically equivalent to 2 ml. of morally by intramuscular injection. The drug can be given in one dose at 8 a.m. or in divided doses at 8 a.m. and 2 p.m. It is rapidly absorbed from the gastro intestinal tract and dieresis usually begins within two hours, reaching its maximum in four to six hours, and is largely completed in 12 hours. For the treatment of edema of mild to moderate severity 0.75-1.0 g. chlorothiazide is usually sufficient. Chlorothiazide or its derivatives should rarely be given on more than three days in the week. Some patients who are resistant to chlorothiazide may respond to morally and vice versa. In resistant cases, a combination of the two drugs given on the same day or on alternate days may be successful. Should this fail, aminophylline should be given in addition.

Chlorothiazide

Since the introduction of the parent compound, chlorothiazide, hydrochlorothiazide, hydroflumethiazide and several other compounds have been produced. In terms of diuretic effect and absence of toxicity there is little to choose between these three preparations. Eventually the choice may be determined on the basis of price. Toxic effects are very uncommon. An increased excretion of potassium results from the administration of each preparation. If given continuously over a prolonged period in doses approaching the maximum, depletion of body potassium with hypocalcaemia is liable to be produced and this can lead to serious illness or even a fatal result. Hence it is essential to prescribe a supplement of potassium whenever chlorothiazide or its derivatives are given more than twice a week. For this purpose tablets or capsules each containing 0.5g of potassium chloride will be found suitable, or a mixture of potassium chloride will be found suitable or a mixture of potassium acetate, citrate and chloride in an orange flavored drink.

Cardiac failure

A great reduction in the cardiac output may also occur with a large myocardial infarction, an attack of paroxysmal tachycardia, fibrillation or flutter, a large pulmonary embolism or a rapidly developing pericardial effusion. The clinical picture of acute cardiac failure is very similar to that which occurs in peripheral circulatory failure, i.e. it is that of shock. Syncope or sudden death may occur. It must be emphasized that a similar clinical picture to that of acute peripheral failure may be seen in circulatory failure of central origin, e.g. in cardiac infarction, massive pulmonary embolism or acute pericardial effusion.

FCS surfboard bags

Wednesday, January 18, 2012

Hi! Surfing, basically, is a tension free surface water sport that most of the people are fond of playing it. Nafis is my dearest friend who didn’t have any idea about water sports. He is an IT professional and he didn’t have much time to relish with his family and allies. As days went on he was vexed and couldn’t concentrate on his work. Gradually his performance went down and he was unhappy and fully packed with stress. One day while he was watching television, he happened to see Kelly Slater, one of the top most surfers from USA playing with the waves. The show entertained him a lot so he decided to watch the show for the next time. Nafis was boosted up a lot to do surfing and he wanted to give it a try. So he borrowed a surfboard from his buddy and went to tutorials. He regained interest in his life and his performance at work sky rocketed. Moreover, Nafis wanted a good bag for safeguarding his valuable surfboard. He gathered information from his friends about the bags and most of them suggested him to buy FCS surfboard bags because it is of premium quality. So he purchased it and was happy with the product because it met with all his expectations. Bye.
