Classifications of Pneumonia According to Causes

Tuesday, December 11th, 2007

Pneumonia is sometimes classified according to the cause of pneumonia:
 
Community-acquired pneumonia : This takes place in the course of your daily life while carrying out daily life activities.

Hospital-acquired (nosocomial) pneumonia : This kind of pneumonia is common with people who are hospitalizedThe chances increases if the patient is on a mechanical ventilator. This type of pneumonia can be extremely serious, especially for old people, young children and people with chronic obstructive pulmonary diseases (COPD) or HIV/AIDS.
 
Aspiration pneumonia : This kind of pneumonia occurs when foreign substance is inhaled (aspirated) into your lungs — most often when the contents of your stomach enter lungs after vomiting. This commonly happens when a brain injury or other condition affects your normal gag reflex.
 
Pneumonia caused by opportunistic organisms : This type of pneumonia strikes people with compromised immune systems.Organisms that aren’t harmful for healthy people can be extremely dangerous for people with AIDS, organ transplantation and other conditions that impair the immune system. For example, P. carinii pneumonia almost never occurs in otherwise healthy people.
 
Emerging pathogens : Outbreaks of the H5N1 influenza (bird flu) virus and severe acute respiratory syndrome (SARS) can also cause pneumonia infection.

Causes of Pneumonia

Thursday, December 6th, 2007

The body of every human being is provided with mechanisms to protect lungs from infection.  The nasal cilia screen out most of the organism in the air passage. White blood cells (leukocytes), a key part of your immune system, begin to attack the invading organisms. The accumulating pathogens, white cells and immune proteins cause the air sacs to become inflamed and filled with fluid, leading to the difficult breathing that characterizes many types of pneumonia. If both lungs are involved, it is termed as double pneumonia.

Other common causes include consumption of too much alcohol. If someone’s unconscious, it’s possible to aspirate the liquid contents and possibly solid food from the stomach into the lungs, causing aspiration pneumonia.

Treatment Options for Pneumonia

The treatment for pneumonia varies depending upon the severity of the disease and the cause of pneumonia.
 
Bacterial : When Bacterial Pnuemonia occurs,the treatment takes place with antibiotic.The full completion of medicine course is neccesary for complete cureness from disease.Incomplete medication create strains of bacteria that are resistant to antibiotics.
 
Viral : Antibiotics are not considered total effective against viral pneumonia.The recommended treatment for the disease is taking rest and having plenty of fluids in diet.However, a few viral pneumonias may be treated with antiviral medications.
 
Mycoplasma : Mycoplasma pneumonias are treated with antibiotics. Even so, recovery may not be immediate. In some cases fatigue may continue long after the infection itself has cleared. Many cases of mycoplasma pneumonia go undiagnosed and untreated.
 
Fungal : In case of fungal pneumonia,treatment with antifungal medication are considered most effective treatment.

Pneumonia symptoms vary depending upon the age factor and causes. Some common symptoms of the disease can be summed up below :-

  • Fever 
  • Cough and cold
  • Unusual rapid breathing
  • Breathing associated with grunting or wheezing sounds
  • Hard breathing in which child’s rib muscles retract.
  • Vomiting
  • Chest pain
  • Abdominal pain
  • Inactiveness
  • Loss of appetite

In some extreme cases,lips and fingernails turns bluish.Sometimes when the pneumonia takes place in the lower part of the lungs near abdomen,breathing problems may be substituted by mild fever and abdominal pain or vomiting.
When pneumonia is caused by bacteria, patient suffers from high fever and unusually rapid breathing. When pneumonia is caused by viruses, symptoms appears more gradually. Wheezing may becomes common in viral pneumonia.

In infants, pneumonia due to chlamydia may cause conjunctivitis (pinkeye) with only mild illness and no fever. When pneumonia is due to whooping cough (pertussis), the child may have long coughing spells, turn blue from lack of air, or make a classic “whoop” sound when trying to take a breath.

Pneumonia Overview

Wednesday, November 21st, 2007

Pneumonia can be better described as inflammatory illness of the lung. It is also known as lung parenchyma/alveolar inflammation and (abnormal) alveolar filling. Alveole is a microscopic air-filled sacs of the lung responsible for absorbing oxygen from the atmosphere. Pneumonia is a common illness which occurs in all age groups, and is a leading cause of death among the elderly and people who are chronically and terminally ill. Pneumonia can occur due to various reasons including infection with bacteria, viruses, fungi, or parasites, and chemical or physical injury to the lungs. The causes can be termed as Idiopathic.
