Signs of "Consolidation"

Signs that consolidation may have occurred include:

* Expansion of the thorax on inspiration is reduced on the affected side
* Vocal fremitus is increased on the side with consolidation
* Percussion is dull in affected area
* Breath sounds are bronchial
* Possible medium, late, or pan-inspiratory crackles
* Vocal resonance is increased. Vocal resonance testing can be done with a stethoscope. Here, the patient's voice can be heard more clearly when there is consolidation, as opposed to in the healthy lung where speech sounds muffled.
* A pleural rub may be present
* Consolidated tissue is radio-opaque, so that it is clearly demonstrable in X-rays and CT (computerized tomography) scans. Consolidation is often a middle-to-late stage feature/complication in pulmonary infections.

What is " Consolidation"

Pneumonia as seen on chest x-ray. A: Normal chest x-ray. B: Abnormal chest x-ray with consolidation from pneumonia in the right lung, middle or inferior lobe (white area, left side of image).





Consolidation is a clinical term for solidification into a firm dense mass. It is more markedly defined as an area of the lung that, while previously collapsible, is now filled with a fluid. It is usually applied to a condition marked by induration (swelling or hardening of normally soft tissue) of a normally aerated lung through accumulation of inflammatory cellular exudate in the alveoli and adjoining ducts. Simply, it is defined as alveolar space that now contains the fluid instead of air. Fluid can be pulmonary edema, inflammatory exudate, pus, inhaled water, or blood (from bronchial tree or haemorrhage from a pulmonary artery). It is clinically important in pneumonia: the signs of lobar pneumonia are characteristic and clinically referred to as consolidation.

"Asbestosis" Treatment

Treatment

There is no curative treatment. Oxygen therapy at home is often necessary to relieve the shortness of breath. Supportive treatment of symptoms includes respiratory physiotherapy to remove secretions from the lungs by postural drainage, chest percussion, and vibration. Nebulized medications may be prescribed in order to dilute secretions.

"Asbestosis" Signs and Symptoms

The primary symptom of asbestosis is generally the slow onset of shortness of breath on exertion. In severe, advanced cases, this may lead to respiratory failure. Coughing is not usually a typical symptom, unless the patient has other, concomitant respiratory tract diseases.

People with extensive occupational exposure to the mining, manufacturing, handling or removal of asbestos are at risk of developing asbestosis. There is also an increased risk of lung cancer and mesothelioma. Asbestosis and lung cancer require prolonged exposure to asbestos. However, cases of mesothelioma have been documented with even 1-3 months of exposure, and only indirect exposure (through air ventilation system.) Most cases of asbestosis do not become apparent until 5-10 years after the initial exposure to the material.

What is "Asbestosis"

Asbestosis is a chronic inflammatory medical condition affecting the parenchymal tissue of the lungs. It occurs after long-term, heavy exposure to asbestos, e.g. in mining, and is therefore regarded as an occupational lung disease. Sufferers have severe dyspnea (shortness of breath) and are at an increased risk regarding several different types of lung cancer.

As clear explanations are not always stressed in non-technical literature, care should be taken to distinguish between several forms of relevant diseases. According to the World Health Organisation (WHO), these may be defined as; asbestosis (the subject of this article), lung cancer, and mesothelioma (generally a very rare form of cancer, but increasing in frequency as people exposed to asbestos age).

"Mesothelioma" Signs and Symptoms

Signs and symptoms

Symptoms of mesothelioma may not appear until 20 to 50 years after exposure to asbestos. Shortness of breath, cough, and pain in the chest due to an accumulation of fluid in the pleural space are often symptoms of pleural mesothelioma.

Symptoms of peritoneal mesothelioma include weight loss and cachexia, abdominal swelling and pain due to ascites (a buildup of fluid in the abdominal cavity). Other symptoms of peritoneal mesothelioma may include bowel obstruction, blood clotting abnormalities, anemia, and fever. If the cancer has spread beyond the mesothelium to other parts of the body, symptoms may include pain, trouble swallowing, or swelling of the neck or face.

These symptoms may be caused by mesothelioma or by other, less serious conditions.

Mesothelioma that affects the pleura can cause these signs and symptoms:

* Chest wall pain
* Pleural effusion, or fluid surrounding the lung
* Shortness of breath
* Fatigue or anemia
* Wheezing, hoarseness, or cough
* Blood in the sputum (fluid) coughed up (hemoptysis)

"Mesothelioma" Diagnosis

Diagnosing mesothelioma is often difficult, because the symptoms are similar to those of a number of other conditions. Diagnosis begins with a review of the patient's medical history. A history of exposure to asbestos may increase clinical suspicion for mesothelioma. A physical examination is performed, followed by chest X-ray and often lung function tests. The X-ray may reveal pleural thickening commonly seen after asbestos exposure and increases suspicion of mesothelioma. A CT (or CAT) scan or an MRI is usually performed. If a large amount of fluid is present, abnormal cells may be detected by cytology if this fluid is aspirated with a syringe. For pleural fluid this is done by a pleural tap or chest drain, in ascites with an paracentesis or ascitic drain and in a pericardial effusion with pericardiocentesis. While absence of malignant cells on cytology does not completely exclude mesothelioma, it makes it much more unlikely, especially if an alternative diagnosis can be made.
If cytology is positive or a plaque is regarded as suspicious, a biopsy is needed to confirm a diagnosis of mesothelioma. A doctor removes a sample of tissue for examination under a microscope by a pathologist. A biopsy may be done in different ways, depending on where the abnormal area is located. If the cancer is in the chest, the doctor may perform a thoracoscopy. In this procedure, the doctor makes a small cut through the chest wall and puts a thin, lighted tube called a thoracoscope into the chest between two ribs. Thoracoscopy allows the doctor to look inside the chest and obtain tissue samples.

What is "Mesothelioma" [Part2/2]

The symptoms of mesothelioma include shortness of breath due to pleural effusion (fluid between the lung and the chest wall) or chest wall pain, and general symptoms such as weight loss. The diagnosis may be suspected with chest X-ray and CT scan, and is confirmed with a biopsy (tissue sample) and microscopic examination. A thoracoscopy (inserting a tube with a camera into the chest) can be used to take biopsies. It allows the introduction of substances such as talc to obliterate the pleural space (called pleurodesis), which prevents more fluid from accumulating and pressing on the lung. Despite treatment with chemotherapy, radiation therapy or sometimes surgery, the disease carries a poor prognosis. Research about screening tests for the early detection of mesothelioma is ongoing.

What is "Mesothelioma" [Part1/2]

Mesothelioma is a form of cancer that is almost always caused by exposure to asbestos. In this disease, malignant cells develop in the mesothelium, a protective lining that covers most of the body's internal organs. Its most common site is the pleura (outer lining of the lungs and internal chest wall), but it may also occur in the peritoneum (the lining of the abdominal cavity), the heart,the pericardium (a sac that surrounds the heart) or tunica vaginalis.

Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles, or they have been exposed to asbestos dust and fiber in other ways. Washing the clothes of a family member who worked with asbestos can also put a person at risk for developing mesothelioma. Unlike lung cancer, there is no association between mesothelioma and smoking, but smoking greatly increases risk of other asbestos-induced cancer. Compensation via asbestos funds or lawsuits is an important issue in mesothelioma
