Pleural Effusions

Asbestos has been used for thousands of years before finally being phased in the late 20th century. However, millions of people were exposed to substances in the United States. Unfortunately, because we are not aware of the dangers of asbestos until it was too late, many people today suffer from diseases caused by this mineral.

Although asbestos is an extremely useful material because of its insulating properties against the head, flame, chemicals, electricity, and humiliation, it is also very dangerous. One was apparently a big feature of asbestos that could easily be made into threads and woven fabrics in and adding other things like plastics and concrete. However, it also means that you can easily stop and come in touch with our bodies.

Because asbestos proliferates so easy, it was associated with several disorders, including:

mesothelioma. This is a specific type of lung cancer that affects the pleura or tissue lining the lungs and abdomen, or peritoneum.

lung cancer. lung cancer occurs when tumor grows in the lung tissue. Many tumors that start in the lung metastasize to other parts of the body, including liver and brain, which makes it especially deadly disease.

asbestosis. This describes the process by which in the lung becomes scarred due to exposure to asbestos. This can disrupt your breathing and cause you to be constantly short of breath.

Pleural plaques. This occurs when asbestos fibers irritate the lungs. They are of scar tissue or fibrosis, deposits of collagen.

Pleural thickening. When pleural plaques cover the lung disorder is called pleural thickening. This calcification, or thickening of the pleura may prevent proper breathing.

Pleural effusions. This occurs when fluid collects between the lining of the lungs and chest wall itself.

Other cancers. contact with asbestos has also been linked with several other cancer except that of the lungs. Larynx, upper throat, kidney, esophagus, bladder, gastrointestinal, and colon.

asbestos warts. When asbestos fibers break off, they can be made in the skin. The skin becomes irritated and inflames, and is growing above the debris. It can form blisters like warts that can be unsightly and embarrassing.

Although not all of the above diseases are deadly and of itself, can often lead to bigger problems or more serious disorders, such as mesothelioma. If you or someone you know has been wrongfully exposed to asbestos and developed mesothelioma, you should talk to a lawyer about their rights.

Journal of Thoracic and Cardiovascular Surgery, Vol 100, 860-866 Here is an excerpt, "histologic and cytologic distinction of malignant mesothelioma cancer metastases in the pleura or peritoneum is often problematic because of immunological method. Increasingly used as diagnostic adjuncts. U this review summarizes 40 studies on carcinoembryonic antigen expression in mesotheliomas and lung and other cancers, including the pleura or peritoneum. carcinoembryonic antigen was identified immunohistochemically in 11% of mesotheliomas and 84% of cancers examined and immunocytochemically (in serous effusion) in 4% and 58%, respectively . in serum and pleural or ascitic fluid, significantly elevated levels of carcinoembryonic antigen are often associated with (lung) cancer, but rarely with mesotheliomas. So, together with the identification of antigens in serum, pleural fluid, or ascitic fluid, immunohistochemical and immunocytochemical techniques for detecting carcinoembryonic antigen to provide valuable help to distinguish malignant mesothelioma from metastatic carcinoma ."

Another interesting study entitled "Production of intrapleural interleukin-6 in mesothelioma and its modulation by γ-interferon treatment" by Gianpaolo Monti, Marie-Claude Jaurand, Isabelle Monnet, Pascale Chretien, Laure Saint-Etienne, Lin Zeng . Alain Portier, Philippe Devillier, Pierre Galanaud, Jean Bignon, and Dominique Emilie - Cancer Res August 15, 1994 54, 4419 Here is an excerpt: "Abstract - In vivo production of monokines was analyzed in 17 human malignant pleural mesotheliomas. High concentrations of interleukin-6 (IL-6) were detected in the pleural effusion, in contrast to the low levels of IL-1β and tumor necrosis factor α. This production originated from the malignant cells, as shown by immunochemical analysis of pleural cells and the production of IL-6 from the mesothelial cell lines. intrapleural administration of recombinant human interferon γ-six patients has led to a significant reduction in intrapleural IL-6 concentrations in all cases. This treatment was associated with in situ activation of macrophages and cytotoxic T-lymphocytes, as evidenced by increased intrapleural neopterin and soluble CD8 concentration. in vitro γ-interferon had no effect on the production of IL-6 by mesothelial cell lines, but reduced growth of 3 of 6 mesothelioma cell lines. These results suggest that systemic manifestations of malignant mesothelioma, including fever, cachexia, and thrombocytosis May apply the production of IL-6 by malignant cells, and that the local infusion of γ-interferon can reduce production by stimulating antitumoral immunity and / or directly reduces the proliferation of malignant cells.

Another interesting study called "long-term survival in peritoneal mesothelioma and the role of radiotherapy in combined modality treatment" by Gilbert S. Lederman MD, Abram Recht Dr. Terence Herman Dr. Robert Defective Dr. Joseph Corson MD, Karen H. antman MD - Cancer Volume 59, Issue 11, 1882 to 1886 pages, 1 June 1987 Here is an excerpt:. "Summary - Ten patients with peritoneal mesothelioma were treated at the Joint Center for radiation therapy between 1968 and 1985. Six out of ten patients remained free of disease at 19 + to 78 + months after diagnosis. Six patients received sequential surgical debulking, combination chemotherapy, and whole abdominal irradiation. four patients not treated with this multimodality approach died with the disease. this approach could have an impact on the natural course of peritoneal mesothelioma, and warrants further study ."

Another interesting study entitled "Somatic genetic alterations in human malignant mesothelioma (Review)." Lee WC, Testa JR. - Department of Medical Oncology, Fox Chase Cancer Center, Philadelphia, PA 19111, USA Int J Oncol .. 1999th January, 14 (1) :181-8 Here's an excerpt: "Summary - review of cytogenetic and molecular genetic findings in human malignant mesotheliomas (MMS) shows a composite profile of somatic genetic changes characteristic of MMS. MultiStep implies a process of tumorigenesis of this malignancy. Specifically , the emergence of multiple, recurrent cytogenetic deletions in MMS suggests that the loss and / or inactivation of tumor suppressor genes (TSGs) are critical for the development and progression of these tumors. Karyotypic and comparative genomic hybridization analysis of MMS showed frequent deletion of specific regions within chromosome arms 1p, 3P, 6Q, 9p, 15q and 22q, and subsequent loss of heterozygosity (LOH) studies have documented high frequencies of allele loss from each of these chromosomal sites. Positional candidate gene approaches have identified TSGs within two of these regions, ie, p16 / CDKN2A at 9p21 and NF2 at 22q12, which are often changed to MMS. homozygous deletion seems to be the main mechanism affecting p16/CDKN2A, while inactivating mutations in combination with loss of alleles occur in NF2 place. high-density LOH analysis of the stress minimum region of deletion in 1P, 3P, 6Q and 15q and is expected to facilitate efforts to identify national TSGs in these places that contribute to the pathogenesis of MMS.

Here is an excerpt: "Abstract - The aim of this study was to assess whether the presence of simian virus-40 (SV40) is associated with an increased release of vascular endothelial growth factor (VEGF) in human malignant mesothelioma (MM) cells Mi. Studied nine cell lines derived from pleural effusion (PE) in patients with MM, and three different cultures of normal human mesothelial cells (NHMC) derived from pleural fluid of patients with congestive heart failure. NHMC were transfected with full length SV40 (NHMC-FL) or large T antigen (Tag NHMC ) DNA. high levels of VEGF were detected in the conditioned media, each of the two MM cells that tested positive for SV40 by PCR amplification and Southern hybridization and dried Tag transcript by reverse transcription-polymerase chain reaction (RT-PCR) and immunoprecipitation. we also found that NHMC-FL released high amounts of VEGF. Conditioned medium from SV40-positive MM cells and from FL-NHMC increased proliferation of human umbilical vein cells (HUVEC) and this effect was partially reversed the addition of specific antibodies against VEGF blocker. These results provide the first evidence that SV40 can cause VEGF release in SV40-positive MM cells and that the whole viral genome is required for this effect ."
