Bronchiectasis

Bronchiectasis is abnormal and permanent dilatation of bronchi and cartilaginous being, accompanied by destruction of muscle and elastic components of the walls.

Etiology and pathogenesis
A bronchial wall inflammation, causing damage and dilatation. Contributing factors are:

1. Infection: primary and secondary.
Primary or secondary infection, either repeatedly or continuously, by: bacteria, viruses, mycoplasma, and mycobacterial clearance mukosilia and will damage the airway epithelium.
In children is often caused by: measles, whooping cough, severe pneumonia or aspiration. Primary tuberculosis is often also leads to bronchiectasis.

Endobronchial tuberculosis causing necrosis, focal stenosis due to endobronchial inflammation, enlarged lymph nodes give emphasis or endobronchial obstruction, and scarring of the parenchyma causes distortion of the airway.

2. Inhalation of toxic chemicals or materials imunoaktif.
Inhalation of toxic chemicals or materials imunoaktif or autoimmune reaction: anhydrous ammonia vapor, sulfur oxides, talc, cork, bakelite, and smoke. Aspiration of gastric contents resulting in inflammation and result in bronchiectasis, for example in the hiatal hernia, gastric motility disorders, divertikuli, trakeoesofageal fistula.

3. An abnormal immune response: a genetic or acquired.
Abnormal immune response: a genetic or "acquired".
Swollen lungs because of heroin or heroin poisoning can cause bronchiectasis, due to changes in immunological defense.
Bronchiectasis occurs in patients with ulserosa colitis, rheumatoid arthritis, Sjogren's syndrome, cutaneous vasculitis, Hashimoto's thyroiditis, pernicious anemia, "primary biliary cirrhosis," "celiac disease", and sarcoid, because of an abnormal immunological manifestations, which often form hiperresponsif or autoimmune response.
4. Mechanical factors.
Atelectasis or parenchymal fibrosis can lead to bronchiectasis. Atelectasis can cause bronchial dilatation is back to normal when the lungs expand again. Parenchymal fibrosis can lead to bronchial dilation through withdrawal.
Bronchial dilatation and distortion may interfere with clearance mukosilier, leads to accumulation of secretions, resulting in infection with bronchial wall damage elements --> bronchiectasis.

5. Inherited or congenital abnormality.
Deficiency of alpha-1-antitrypsin causes emphysema panasinar and diffuse bronchiectasis.

  • "Allergic bronchopulmonary aspergillosis" --> central or proximal bronchiectasis.
  • BEAP syndrome (bronchiectasis, eosinophilia, asthma, and pneumonitis).
  • Bronchiectasis is a picture that stands out in cystic fibrosis, in children and adults.
  • Kartegener syndrome (bronchiectasis, sinusitis, site inversus).
  • Young's syndrome: obstructive Azoospermia and lung abnormalities (bronchiectasis).
  • "Pulmonary sequestration".
  • Yellow nail syndrome.
  • William Syndrome - Campbell (deficiency of bronchial cartilage generation 4 through 8).
  • Swyer Yndrome - James and Mac Leod (hipertensi unilateral lung).
  • Marfan's syndrome.

Pertussis (Whooping Cough)

Image
Definition Pertussis (Whooping Cough) is an acute disease of the respiratory tract. Found in children younger than 5 years, especially in children age 2-3 years. Cause Pertussis is caused by gram-negative Bordetella Pertussis. Clinical Overview These symptoms occur 1-2 weeks after contact with the infected person and preceded by an incubation period of 7-14 days. Typically, the disease lasts for 6 weeks or more. That is why the disease is called cough hundred days. On his way, pertussis includes several stages, namely: Kataralis which marked the onset of a mild cough, especially at night, accompanied by mild fever and runny nose. This stage lasts 1-2 weeks. In the catarrhal stage indistinguishable from that caused by a viral respiratory infection Second is the spasmodic stage lasts 2-4 weeks. Symptoms, cough more often, people with sweat, and blood vessels in the face of wide-neck. Long coughing attack usually ends with a distinctive high-pitched sound (whooping caugh) and accompanied ...

Hemothorax

Image
Hemotorax is the presence of blood in the pleural cavity. Pathophysiology and Etiology Sharp trauma or blunt trauma. This can occur when blunt trauma can cause fractures of the ribs, resulting in a torn intercostal blood vessels and also cause a tear in the lung tissue. A torn aortic aneurysm Complications due to drug administration on pulmonary infarction antikoagulansia In patients with abnormalities of "hemorrhagic diathese". Complications in thoracic surgery. Clinical Symptoms Symptoms and complaints hemothorax depending on the weight and severity of trauma. Patients may complain of shortness of breath, chest pain, until the shock and anemia. Diagnosis 1. Anamnesa : A history of trauma to the chest, or after surgery. 2. Physical examination Found such signs in the pleural effusion . At the hospital hemitoraks reduced movement. Hemithorax percussion on the sick and faint sounds on auscultation, breath sounds audible reduced or disappear altogether. 3. Chest X-ray photo...

Cough - Definition and Mechanisms

Image
Cough Cough is a symptom of the most common disease in which the prevalence was found in about 15% in children and 20% in adults. One out of ten patients who visited the doctor's office each year has a chief complaint of cough. Coughing can cause bad feelings, sleep disorders, affecting daily activities and reduce quality of life. Cough is a complex physiological reflex that protects the lung from mechanical trauma, chemical and temperature. Coughing is also a natural defense mechanism of lung airway to keep it clean and open to the street: Prevent the entry of foreign objects into the respiratory tract. Remove foreign objects or abnormal secretions from the respiratory tract. Coughing becomes physiologically when perceived as a nuisance. Such a cough is often a sign of a disease within or outside the lungs and sometimes are the early symptoms of a disease. Cough may be very significant on the transmission of disease through the air (air-borne infection). Cough is one of the sympto...
