Bronchitis

The bronchitis consists on the inflammation of the bronchial tree, accompanied by an excessive production of mucosity. The acute variety of bronchitis, very current, usually determines scarce incompetence. On the contrary, the chronic form is important, since he/she goes accompanied by intense dysfunctions of the respiratory feature and frequently continued of emphysema, and it can even drive to the death for bronchopneumonia or acute and cardiac breathing failure.

In the case of the acute bronchitis, you are about a process that can dearrollarse like the initial manifestation of an infectious illness, as the measles and the typhoid fever, or parallelly to an acute bacterial pneumonia. In chronic bronchitis they are sometimes observed symptoms of an acute, unchained bronchitis, apparently, for the ación of irritating factors, rather that infectious, such as the substances that pollute the atmosphere.

You frequently begin with nuisances retroesternales, due to the inflammation of the trachea and dry, difficult and painful cough, in crisis form or paroxysms. The exhibition to the cold air and the inhalation of irritating agents, as the tobacco plant, they make worse the crisis of cough. Frequently he/she goes accompanied by noisy and perceptible respiration; and at the beginning, it is usually escalsa the expectoration of the mucus, which are made then more abundant and I thicken.

The bronchitis agudade the children evolve in a very serious way, because of the pneumonia that originate.

As for the chronic bronchitis, you are characterized by cough and expectoration that it persist the whole year, with abundant secretion of bronchial mucus and inflammatory alterations of the bronchial wall.

The factors that intervene in the setting-up of the chronic bronchitis are several and they are not still very well-known. The frequency of due deaths to this illness increases with the age, and you are eviodente the prevalence of the men on the women.

You are difficult to establish the paper carried out by the sick person's profession in the origin of this illness, but the certain thing is that you take place with more frequency in the industrial fields. You are suspected firmly that the sludges of the atmospherical air influence notably in the path and disease progression. You seem also to be certain that the nicotine inhaled with the fume of the tobacco plant acts directly on the bronchial mucosa and you force her to segregate an excessive quantity of mucus; however, all the smokers of cigarettes not suffer bronchitis, that which make suppose that certain individual and family susceptibility exists.

The development of the chronic bronchitis is manifested by intermittent crisis of acute bronchitis, mainly in the months of winter, crisis of which it are more and more difficult to recover. In general, the illness begins in way inidosa, although it can begin in an acute way. Many sick persons allocate your promeros symptoms to some infectious acute process, as pneumonia, measles, whooping cough, etc.; other, simply to smoke. The progress of the chronic bronchitis is co patent frequency, until transforming into a suffering that last the whole year, with acute exacerbations. This state frequently leads to the death, well for rough pneumonia, well for breathing failure or cardiac right, to the end of 20 or 40 years after your beginning.

The influence of the atmospherical state, is fully grateful, and you are notorious the aggravation of the symptoms the days of cold, wet time and with mist.

Pneumonia

The inflammations of the lung or pneumonias (commonly pneumonias), they are usually produced by bacteria but viral pneumonias, rickettsiósicas, etc also exist. the germs pathogens arrive to the lung transported by the blood stream, or for top-down propagation of infectious processes of the respiratory higher channels: rinitis and pharyngitis that, if they descend, they can give place to laryngitis, to traqueítis, to bronchitis and even to infections of the own lung.

Conjointly with the pneumonias we should mention the bronchopneumonias. In the pneumonias a pulmonary single inflammatory focus exists, of enough extension: it embraces to great part of a lobe, to one complete, or to more than one. In the bronchopneumonias the pulmonary inflammation is plurofocal: the aflame fields of the lung are usually pettier than in the pneumonia, but they exist different. The same germs that cause the pneumonias can give origin to bronchopneumonias.

The pneumonias and bronchopneumonias are always important illnesses. They study with deep prostration, fever, side (if the focus inflammatory wound until the pleura) pain, cough with scarce expectoration and breathing difficulty.

The most frequent bacterial pneumonia is the neumocócida. 90% of the bacterial pneumonias is neumocócidas and they are very sensitive to the antibiotics, especially to the penicillin.

Commonly it is believed, and until many physicians they admit it that from the input of the antibiotics in the treatment of the infections, the frequency of the pneumonias has diminished a lot of .Pero the reality it is that the pneumonias continue being as frequent as before the antibiotic and chemotherapeutic therapy; what has diminished has been its graveness and mortality: the systematic practice, in hospital centers, of thorax x-rays in patient acute affections of respiratory infections confirms it. But given the effectiveness of the antibiotics in the pneumococcal pneumonia, and to be this the most frequent bacterial pneumonia, many of these illnesses, are cured without book credit diagnostigadas.

Myths of the Science Top 10

1. The water falls a contrario sensu in the South Hemisphere due to the wraparound of the Earth
The wraparound of the Earth is too weak as to affect to the sense in which turns the water while he/she falls in a sink. Anyone can check it easily with only to turn on the faucets of several bathrooms. In each place he/she will see as the water it forms whirls to one or another side only depending in the way of the washbasin, not of the hemisphere where he/she is.

2. The alone human beings use 10% of the brain
This difundidísimo myth already takes almost one century being even reverted in the means. Fortunately it is not certain. The investigation techniques for such images as the Magnetic Nuclear Resonance have demonstrated that the humans even make good use of the cerebral cortex when they sleep

3. A chicken can live without head
Certain, and also during enough time. A rooster can outlive without head because his cerebral trunk is often practically intact after beheading it, puediendo still to control for if same most of its motor skills.

4. In the space there is not graveness
The blame of this frequent equivocation is for the image that we have of astronauts floating inside a space ship. When an object (a satellite, a shuttle) is in orbit, it is not in ingravidez (since the graveness yes it acts) state but in state of free drop. This means that said I object in fact he/she is falling toward the Earth, but I eat their tangential speed it is so high, the floor is "curved" quicker, and therefore the object never ends up playing the floor. The graveness is everywhere, even in the space. Neither it is certain that the space is a hole. There are there outside all kinds of atoms, although often very distant.

5. A currency rushed from the high of a building could kill a person
A petty currency, as that of 5 cents of euro, is not in fact the most aerodynamic weapon that exists. Due to their form and to the friction of the wind it would only be able to reach the enough (even being heady from the high of Empire State Building to 381 meters) speed it hardly stops to cause smarting to the unfortunate pedestrian.

6. In the mature brain new cells are not generated
It has always been accepted that each human was born with a certain number of neurons that he went losing throughout the life without reserve possibility. It is certain that most of (and more important) the development of the brain happens during the childhood, but that doesn't mean that everything is below hill starting from then. The studios have demonstrated that the bigger one is even able to generate new brain cells during, and that these work correctly.

7. The men think of sex every seven seconds
The males, in evolution terms, come genetically scheduled to reproduce, but scientific method doesn't exist some to be able to measure how long of the day they spend it fantasizing. Fortunately for the world productivity, do those seven seconds only seem a coarse exaggeration, truth?

8. A ray never falls twice in the same place
In fact the lightnings take their "favorite" places, especially in the places to great height. For example to Empire State Building hits upon him some 25 times a year. Benjamin Franklin understood the concept a long time ago. He/she climbed with a metal bar on the roof of their house, to which bound until mediating earth a conductive cable. It had just invented the lightning rod.

9. The chicken broth cures the common cold
To use the word to "cure" is maybe exaggerated, but the science says that the mothers from all over the world make well when they force their children to take soup of chicken broth. The studios have found that the broth contains anti-inflammatory estates that you/they help to reduce the engorgement.

10. The hair and the nails continue growing after dead
Although the hair and the nails seem to continue growing post-mortem, this is merely an optical morbid illusion. In the death the human body becomes dehydrated severely, retrayendo the skin enough how to expose the nails and the hair more than the habitual thing.
