MEN syndromes Flashcards
MEN 1 Syndrome
Causes neoplastic mutations of the pituitary, parathyroid and the pancreas. It is caused by mutations in the MEN1 gene.
MEN 2A Syndrome
Caused by mutations within the RET oncogene. Results in medullary thyroid cancer, phaechromocytoma and parathyroid adenoma.
MEN 2B Syndrome
Caused by mutations within the RET oncogene. Results in medullary thyroid cancer, phaechromocytoma, mucosal neuroma, gastro-intestinal complaints, craniosynostosis
what two combination of drugs cause serotonin syndrome
SSRI taken with MDMA as increase serotonin activity in the brain

Mental status changes
Autonomic hyperactivity - g., sweating, palpitations, dry mouth, lightheadedness, upset stomach).
Neuromuscular abnormalities.
FIT tests are offered every 2 years to men and women aged 60–74. Patients who receive a positive FIT result should then be offered
a colonoscopy. This is the first-line investigation as it allows both for visualisation of the colon with identification of malignant or premalignant lesions and for biopsies to be taken.
what patient type would require urgent referral via oral cancer pathway
Patients with unexplained ulceration in the oral cavity lasting for more than 3 weeks should be referred under the suspected oral cancer pathway.
what breast cancer treatment can cause vaginal spotting and why
Tamoxifen is a oestrogen antagonist, commonly indicated for ER+ positive breast cancers. However, it also works as an agonist on endometrial tissue which can result in endometrial proliferation and cause abnormal vaginal bleeding.

Total proctocolectomy
Prophylactic removal of the large bowel is the best treatment available for familial adenomatous polyposis, which carries nearly a 100% risk of colorectal cancer by the age of 40 in untreated patients.
Li Fraumeni syndrome
A rare autosomal dominant disorder. It is the result of germ line mutation of the p53 tumour suppressor gene. It leads to an increased risk of sarcoma and cancer of the breast, brain and adrenal glands.
