Respiratory Services, Green Lane Hospital, Auckland, New Zealand.

Approximately 20% of pleural effusions remain without an established aetiology after evaluation. Thoracoscopy has a very high sensitivity for the diagnosis of both benign and malignant diseases and greatly increases the diagnostic yield for pleural effusion. We sought to evaluate the diagnostic yield and safety of medical thoracoscopy at this institution.

The records of all patients undergoing medical thoracoscopy for the evaluation of undiagnosed pleural effusion between 1990 and 1996 were reviewed. The procedure was performed under local anaesthesia with sedation using a Stortz rigid thoracoscope. Fifty-eight patients had thoracoscopy, most having had two (range: 1-6) non-diagnostic pleural aspirations and biopsies of the pleura. Nineteen patients were found to have mesothelioma and nine metastatic malignancy. Three patients were considered likely to have tuberculous pleural disease, six had asbestos related benign pleural fibrosis and three post-cardiotomy syndrome.

There was one chylous effusion of uncertain aetiology, one posttraumatic and two other benign effusions, both of which resolved without clear aetiology. On seven occasions the pleural space could not be adequately accessed, but none of these patients had prior computerized tomography (CT) or ultrasound of the pleural space. There were five false negative diagnoses of malignancy, but no false positives.

The diagnostic sensitivity for pleural malignancy was 85% and specificity 100%. There were no major complications, but four patients had late tumour seeding at the thoracoscopy site. Medical thoracoscopy is a safe procedure with a high diagnostic yield. Pre-operative evaluation of the pleural collection using ultrasound or CT increases the likelihood of successful access to the pleural space and may increase diagnostic yield.

Asbestos, the natural condition of silicate complex that was largely in numerous industries, including the insulation in the shipbuilding, the manufacture of brake pads, and the cars. Asbestos is a name given to a group of six fibrous minerals, their existence in two general forms, and not crumbly, crumbly. Bröckelige émietté asbestos is the most dangerous form of a powder, also on the application of the pressure of the hand. It is relatively difficult to demystified brittle asbestos is not in powder form. However, in a very damaged, asbestos, is not crumbling to powder émietté to apply pressure, even minimally. The dry powder of asbestos or asbestos, crumbling, crumbly are dangerous to human health, and therefore should be treated with caution, carefully packed and removed.

This time, in the United States, more stringent measures have been taken to the preventive control of the exposure of these hazardous substances in the industry. The limits for occupational exposure to asbestos fibers longer than 5 microns, respectively. However, it should be borne in mind that asbestos, a carcinogen in humans, not on safe handling.

The toxic effects caused by the inhalation of asbestos containing desquamating alveolitis, bronchiolitis, and lung fibrosis. Other more serious illnesses to health from exposure to asbestos pleural effusion, plates pleurales a calcification pleural fibrosis and mesothelioma (malignant).

Asbestos lawyers are lawyers who specialize in cases that are tailored to the harmful effects that are caused by asbestos. They work in the field of law and bring to justice in the form of compensation for those who have a negative effect on their health, because of asbestos in the present and / or past environment. Asbestos is a process of several billion dollars, the industry of lawyers and law firms specializing in the provision of compensation for people who suffer or suffered from mesothelioma and / or other serious problems of asbestos on health inconvenience.

For some time, this element of danger was always the goal, the win by fraudulent acts, the people who have an interest in the capital gains of false means. This is not submitted, in all cases, the right unreal, and not all of them are not worthy of compensation.

If the suspect is Erguß for certain infections or cancer, a sample of the liquid, the idea of whether benign or malignant. However, four of the five tests can be less cancer. Finally, the biopsy of the pleura with a needle or by an operation confirms the diagnosis of Mesothelioms.

For the abdominal mesothelioma, an abdominal X-ray checked the liquid in your stomach.

Sometimes an X-ray show not only the martyrdom, but also the mass, or the collection of signs, asbestos, plates and pleurales calcifications or scar by asbestosis and chronic inflammation.

Drain the liquid from needles in the chest or abdominal cavity. The name is thoracocentesis vacuuming or pleural fibrosis of the breast, and abdoparacentesis peritoneal aspiration or in the abdomen.

In modern days, CT (computer tomography) scan is more frequently. CT is a device, the X-ray image shows images of the slices of your body. Tomodensitométrie the chest or the abdomen shows the swelling of organs, which caries, and the lymph nodes. A contrast ratio of tincture can help to the analysis. Tomodensitogrammes show pleural effusion, pleural effusion thickening, pleural fibrosis calcification, the spread of the tumor in the chest wall. But CT is not really distinguish the benign disease that asbestos, lung cancer and mesothelioma. The doctors have also lead to action, for the computed tomography, the needle desire of the masses suspicious pleural mesothelioma.

Thoracoscopie is the procedure when a surgeon makes small notch in the chest wall between the two coasts and looks through a thoracoscope (a tool with a video camera). The biopsy (tissue sample) is in a laboratory to the cancer cells.

Bronchoscopy, the physician may look into the airway. A thin flexible hose (bronchoscope) allows samples of tissues and sent to a laboratory for the testing of cancer cells.

Médiastinoscopie controls funds coat (the zone with heart in the chest, large blood vessels, lymph nodes, esophagus, nerve, etc.). Médiastinoscopie allows for the removal of the lymph nodes in the body after the metastases.

The Laparoscopy is a surgical procedure where doctors look in your stomach with a small camera with a hose. The surgeons are biopsy suspicious areas. The bioptate (the sample of the tissue) in the laboratory. A doctor under the microscope. Laparoscopy can be a small cut in the skin of your abdomen. Another name for the same procedure is peritoneoscopy. The tool is peritoneoscope appointed.

A needle in the abdomen area and removal of liquids in the name paracentesis a needle in your chest to drain the fluid and will thoracentèse.

The MRI (magnetic resonance imaging) scan is a photo cut out of your body. That is better than X-ray or computed tomography, as there is no radiation in your body. But it requires a lot of time. It may take up to 20 minutes. And some people are afraid to stay in the machine for half an hour for the exam. In addition to the MRT has a limit. The test requires avoid metals in your body (such as seals made of metal and other metallic implants). The IRM is not a test program, so sometimes it is not ordered. Magnetic resonance imaging is commonly arranged in order to determine the extent of the tumor in the area of surgery. The MRI also easier than CT shows swelling of the lymph nodes and the surface of the membrane, and it is important for the planning of surgery.

Positron emission tomography (PET) recently came for the diagnosis of various types of cancer and mesothelioma so. PET uses of radioactive materials, which emits positrons. City mesothelioma is on the pleura. Advanced mesothelioma in the lungs, the wall of the chest, abdomen and lymph nodes.

Pathology examination of the samples under a microscope reviewed biopsy It is difficult to diagnose mesothelioma sometime. The cells of the tumor are different species. These cells can be like other types of cancer. Péritonéale cells as pleural mesothelioma, or other types of lung cancer and ovarian cancer. Epithelioid kind mesothelioma is more frequent and better, for longer than an aggressive type sarcomateuse. Biphasique that mesothelioma is a mixture of the two.

The doctors and scientists have proposed a number of immunological decision-makers to find mesothelioma, but the majority of the markers are not very precise. Just to signal: Epithelial membrane antigen, the CEA (carcino-antigen √ very inaccurate, it can in many cancers), Calretinin, Mesothelin, Cytokératine, ostéopontine and some others.

So, to summarize, the tests carried out by the doctors:

* X-Rays

* Tomodensitométrie

* Thoracocentesis

* Paracentesis

* Thoracoscopy

* Bronchoscopy

* IRM

* Media-Tino’s Copy

* Laparoscopy

* All types of biopsy

The diagnosis is made after a careful evaluation of symptoms, physical examination and imaging in the biopsy.

Introduction

Today there is much discussion in the world, both offline and on the Internet, via the mesothelioma. In the United States, there are groups awareness mesothelioma in almost every city in the United States. In addition to the discussion forums, legal mesothelioma cells, mesothelioma forums, groups, etc. awareness mesothelioma, mesothelioma, which today is a very broad topic. There is even a mesothelioma Memorial Scholarship, it is proposed that each quarter. The scholarship is in memory and honor, those who were affected, by mesothelioma. Billions of dollars have been spent to try to make the fight against this terrible disease and a cure to be found. Let us begin, ask this simple question - what is that mesothelioma?

What is mesothelioma?

Asbestos and mesothelioma infâmant are bound. The Mesothelioma is a form of cancer affects people who were exposed to asbestos. It is a rare form of cancer, and touched that the people who have a story created by asbestos, others not. However, it may be secondary, in which a person can be in touch with someone who was asbestos in the past. The key for mesothelioma, as well as here, is the risk from asbestos.

The main cause of mesothelioma is an asbestos exposure. Once the patient inhaled asbestos dust / fibres, other factors such as smoking, the situation in a period of time. It may also have other causes mesothelioma. For example, there were cases in which patients diagnosed had no history of asbestos exposure. People can use it to the people, that the asbestos exposure. Before proceeding, define mesothelioma.

Mésothéliome Definition: The mesothelioma is defined as a rare form of cancer, often in connection with a previous exposure to asbestos. In this disease, malignant (cancer) in the cells of the mésothélium develop protective fairing, the majority of the organs of the body. Mésothéliome malignant cells proliferate in the affected area, and are usually very difficult to reduce.

The mesothelioma has come to be widely known, only about 60 years old, if the symptoms have begun to manifest, and the cases of mesothelioma diagnosed. Across America, for the people who are in institutions, in connection with asbestos, it is a nightmare. It was more because at the time, asbestos, because of the many advantages that other metals, was often in all industries around the world. It was a tragedy, the epic proportions, which is expected to be triggered when it was triggered, he devastated the lives of people everywhere in America. Thousands lost their lives for the mesothelioma, and even today, thousands of others remain in the fight against this terrible disease.

Even today, more than 3000 people will receive a diagnosis of mesothelioma in the United States. Today, the mesothelioma victims and their families struggling to cope with the disease. For the survivors mesothelioma court action against the industries in which the disease on them was a exorciser through the pain and suffering that they had to suffer. For a number of victims of mesothelioma lawyers were in a position to the business with success. There are groups of mesothelioma mesothelioma support for the victims and their families for life, resulting from the disease. There are websites, like www.mesotheliomaweb.org, www.mesothelioma.com, www.cancer.gov, etc.

The mesothelioma is extremely violent, for several reasons:

• The mesothelioma diagnosis is often very late. It shows itself in a person after years of asbestos exposure, so long, that 15 to 20 years ago.
• During the period of pregnancy is very long, it is as mentioned above, the time of the exhibition is very short, less than two to three months. This means that the person is not even necessary, for a longer exposure.
• The average life of a person, after diagnosis, is very short, about 24 months.
• It is not just a person who is exposed to asbestos, the chances that it is possible, are you in the dust or asbestos fibers also expensive.

Types mesothelioma

Mainly, the mesothelioma is divided into three areas on the basis of mesothelioma is divided into two categories:

• pleural fibrosis mesothelioma (pleural mesothelioma, the exterior coating protects the chest cavity and the lung)
• pericardial mesothelioma (Pericardium of mesothelioma, the bag surrounds the heart)
• peritoneal mesothelioma (mesothelioma of the peritoneum, the wall to protect the abdominal cavity)

Based on the types of cells, in a mesothelioma patients who have mesothelioma can into 3 types:

• Epithelioid mesothelioma (about 50 to 70 percent of all cells mésothéliales)
• Sarcomatoid mesothelioma (less commonly mesothelioma cell type, about 10 to 15 percent)
• Biphasic mesothelioma. (Approximately 20 to 40 percent of all cells mésothéliales)

The symptoms of mesothelioma

The symptoms of Mesothelioms depends on the type of Mesothelioms a patient can have. If a patient with a malignant pleural mesothelioma, usually feel pain in the chest, accompanied by shallow breathing. These symptoms occur because of the submission of fluid in the pleura.

Mésothéliome peritoneal symptoms differ from those of pleural mesothelioma. In the case of peritoneal mesothelioma found, the symptoms are:

• Fever
• difficulties in the chair
• Anemia
• The abnormalities in the course of blood clots

In the case of peritoneal mesothelioma, the symptoms include pain, swelling of the face or the neck, and the difficulties of absorption.

Mésothéliome card symptoms of other, less serious inconvenience. Therefore, it is advisable to consult a doctor to ensure that the symptoms show.

The diagnosis of Mesothelioms

Mésothéliome diagnosis is not an easy task, because the symptoms of the card to a lesser other diseases, as already mentioned above. The first step for the diagnosis of mesothelioma is a journal in the history of medicine to the patient. It is important to know whether the patient has a disease whose symptoms shows to mesothelioma. At this point, it is also important to know whether the patient previously asbestos. If the patient is not disease, the symptoms associated with mesothelioma, and had an asbestos exposure, then it may be suspected mesothelioma.

It is important to have a physical examination of patients, including X-ray, magnetic resonance and tomodensitogrammes. The focus is usually on the regions of abdominal and chest. If there is something suspect after conclusion of the investigations, it is advisable to a biopsy.

A biopsy is usually by a specialist or a surgeon or oncologist. Biopsy is a sample of tissue of the patients and to undergo tests to determine the presence or absence of mesothelioma. Biopsy with mesothelioma:

• Thoracoscopy (by the taking of samples of tissue inside the breast, with a thoracoscope)
• Peritoneoscopy (by the taking of samples of tissue from the abdomen, with a peritoneoscope)

Once the diagnosis, it is necessary to know which step mesothelioma was found. Depending on whether the cancer is still in its original position, or, if they stick to the other parts of the body, which can be called mesothelioma:

• City (still in its original location)
• Advanced (spreading to other parts of the body)

Treatment of Mesothelioms

Mésothéliome treatments according to mesothelioma, as in the phase where it is found. The three treatments, the most common forms of the Mesothelioms are:

• Surgery - Surgically abolition of part of the body of cancer patients. For example, the treatment of malignant pleural mesothelioma could also include the abolition of the lungs caused by the execution of a lung resection.
• The radiation therapy - Bring the affected party of high-energy radiation to kill the malignant cells
• chemotherapy - using chemicals or drugs to destroy malignant cells, either by injection or by the patient intravenously or through direct placement in the chest or the abdomen (intracavitaire chemotherapy).

In addition to these three options, the investigations are still under way for the latest and most effective treatment options. Clinical studies have an important role in the development of new choice of treatment.

Mésothéliome forecast

In the case of mesothelioma, the prognosis is not as precise as with other diseases, less serious. This is because normally the prognosis depends on the phase in which a disease is detected. The mesothelioma is usually very late detected, the patient, so that it becomes difficult to maintain the healing or for the life of a patient after treatment. Regardless of the available statistics are not as reliable as we would like. Although it was not easy to determine which of the two - or pleural effusion peritonealer - Mesothelioma is difficult to stage, the experts agree that in general, the prognosis is very difficult for the two.

But recent studies and researches have shown that patients with mesothelioma is perhaps not as bad as it was originally believed start. These data are included in the following tables.

Stage discovered Mesothelioma chances of survival (No. years) Percentage of Patients

Mid at an advanced stage 3 years 10%

5 years 5%

First Steps 2 years 50%

5 years 20%

It is not that general information on the prognosis of Mesothelioms. There are certain data available to Internet-n-scenarios and situations.

As we have in our previous articles, maybe you have asbestos in the air suspended particles, if you have to build the ships, in conjunction with thermal insulation and changing old brake pads. There are many professions are dangerous, as the asbestos factory workers in the automotive industry, machinery, steel, tin, the Scotsman dry, insulating electricians, painters, hairdressers and even teachers. Many other professions to give an occasional exhibition of asbestos particles.

As the result of exposure to asbestos, you can amiantose, but you can also with the establishment of a mesothelioma - relativity theory rare but deadly type of cancer.

Then, as the doctors mesothelioma?

If your doctor, the first think that there is no reason to suspect mesothelioma is the question relates to your professional history. The importance is the cancer of asbestos in the early stages of the disease, when the time is crucial. The survival rate is eight to twelve months on average. But the collection and treatment of early detection Mesothelioms to some types of cancer to better results.

Doctors are looking for, the signs and symptoms of cancer. The mesothelioma symptoms often up to 20 or more years after exposure to asbestos. But in rats within pleural mesothelioma introduction of chrysotile asbestos fibers can mesothelioma in several months.

People complain about mesothelioma breathing difficulty breathing, persistent cough, sputum and chest pain. The pain from the pleura - lung coating, which is very sensitive to the irritation. Mesothelioma tends to the accumulation of fluid in the pleural fibrosis cavity.

Mesothelioma peritoneal causes of weight loss, the pain and ascites (swelling of the abdomen due to fluid in the abdominal cavity). Mesothelioma peritoneal can also block the intestines and cause all sorts of trouble with Disabilities good. Like many cancers, asbestos cancer also changes coagulation, which causes decrease in blood cells (anemia), night sweats and fever. Abdominal water can cause nausea and foot in the tuber. Étalement cancer is the pain, difficulty in swallowing, and the nodes in the neck. This problem occurs because the compression of several large veins, in sharp in the chest. In general, the symptoms of mesothelioma are not very precise. You can characterize all other types of cancer and many other diseases that are not cancer cells. The problem of delays in diagnosis. Sometimes the patients who believe they have a viral pneumonia. Some patients show no symptoms at all. Mesothelioma in advanced stages, and most cancers, the cause fatigue.

An X-ray may show a collection of fluid.

What is a pleural effusion? Épanchement pleural mesothelioma is the accumulation of fluid in the pleura between the inner chest and diaphragm, lungs and pleura. What is the pleura? Plèvre is the thin layer of cells, the lung specialist and the internal chest. He has an idea of a closed plastic bag with a small amount of liquid inside. Basically this bag, who easily to the lungs chest wall in the expansion of breathing. The pleura is the membrane of cells mésothéliales. Exactly these cells produce a small amount of lubricant. The amount of the liquid is always in the balance. Extra fluid pleural mesothelioma is fast réabsorbé. If there is too much liquid, the Erguß. Abdominal cavity lining similarly notified of the peritoneum, based on the way in which abdominal pleura cover the lungs. Mesothelioma leads to fluid, caused by cancer cells in the pleura or peritoneum irritant. This disease leads to fluid in your stomach or difficulty breathing.

Transsudation with pleural effusion is a clear liquid. It shows that in general, by an imbalance in the production of liquid and relocation costs. It is characteristic for a different disease. Doctors should think first of heart failure. Mesothelioma prefer an exudate. Exsudats are a pleural effusion cloudy with a lot of cells and proteins. Exsudats according to the pleura is irritated and inflamed, as it is in the mesothelioma. In order to verify the nature of spitting, the doctors of a needle and a sample of the liquid. The stock is considered thoracentèse diagnosis. The fluid is examined in the laboratory. If that is the cause mesothelioma, the cancer cells can be in the liquid

Why is the shortness? The dyspnea (breathing difficulty breathing) just happens because fluid accumulates, and press the lungs, expresses far the chest wall and inside of the lungs smaller. Also, the pain caused by inflammation of the pleura patients prevents the deep breathing. The inflammation of the pleura receptors to a dry cough. Lightning rod for the lungs with a stethoscope shows decreased breath sounds. If you are breast sounds meager. All of this is a consequence of the accumulation of fluid.

During the visit from your doctor should discuss your concerns about the risk from asbestos in the past. Your doctor should check the area of pain and the tuber is, it should also hear your sound and breath to the collection of fluids. If your doctor suspect, it can Erguß of tests and X-rays or to a specialist.

If a doctor suspect mesothelioma, dose not many tests on the hands. Many of the standard tests can no results in the mesothelioma. Simply radiograph of the chest shows are not always small pleural effusion. A film by décubitus page can be required to small fluid collections (the same X-rays, but from the side). If not, computed tomography or ultrasound can show the effusion.
