Mycobacterium: TB & NTM
Q: The Mantoux tuberculin skin test measures a Type IV (delayed) hypersensitivity reaction. True or False?
Did You Know?
False. While the exact cause of endometriosis is not fully understood and involves genetic and immune factors, there is a growing body of scientific research suggesting a potential link with exposure to certain endocrine-disrupting chemicals (EDCs). Dioxins, polychlorinated biphenyls (PCBs), and some phthalates have been investigated in this context. The hypothesis is that these EDCs, which can have estrogenic or inflammatory effects, may promote the survival, attachment, and growth of displaced endometrial cells. They might also alter immune function in ways that fail to clear these cells. Animal studies have shown that exposure to dioxins can increase the incidence of endometriosis-like lesions. Human epidemiological studies, while complex, have reported associations between higher body burdens of some persistent organic pollutants and an increased risk or severity of endometriosis.
