Study Notes
Inherited Metabolic Disorders
- Cystic Fibrosis is the commonest serious inherited metabolic disorder in the UK.
Cystic Fibrosis
- The abnormal gene associated with Cystic Fibrosis is located on chromosome 7.
- Cystic Fibrosis is NOT characterized by tumors in the pleura, as it is a disease affecting the respiratory, digestive, and reproductive systems.
Pleural Tumors
- Secondary pleural tumors are more common than primary pleural tumors.
- Secondary pleural tumors appear as multiple, small, and nodular lesions on the lung surface.
Clinical Manifestations of Cystic Fibrosis
- Cystic Fibrosis has various clinical manifestations, EXCEPT for tumors in the pleura.
Metastasis to the Pleura
- Malignant tumors that most frequently metastasize to the pleura are adenocarcinomas.
Mesothelioma
- The most common cause of mesothelioma is exposure to asbestos.
- A mesothelioma tumor on the pleural surfaces typically appears as a diffuse, thick, and nodular lesion.
- Mesothelioma is NOT characterized by diarrhea, as it is a neoplasm that affects the lining of the lungs, abdomen, or heart.
Test your knowledge on the pathogenesis and epidemiology of Cystic Fibrosis, the commonest serious inherited metabolic disorder in the UK. Learn about the autosomal recessive abnormal gene and its impact on chloride ion transport across epithelial cell membranes.
