Which of the following are risk factors for abdominal aortic aneurysm (AAA)? (Select all that apply.)
Diabetes mellitus
Total cholesterol 170 mg/dL (less than 200 mg /Dl
HDL cholesterol 65 mg/dL (male greater than 45 mg/dL; female greater than 55 mg/dL)
Smoking cigarettes
Family history of aneurysm
Correct Answer : D,E
A. Diabetes mellitus: An inverse association between diabetes mellitus (DM) and abdominal aortic aneurysm (AAA) risk has been reported. Apart from a lower AAA prevalence among patients with vs those without DM, there is data showing that DM may exert a protective role on aneurysmal growth in patients with small AAAs, thus decreasing the risk of rupture. As atherosclerosis has almost the same risk factors as aneurysms, the decreased AAA prevalence in patients with DM may indicate that atherosclerosis is an associated feature and not a cause of the aneurysms.
B. Total cholesterol 170 mg/dL (less than 200 mg/dL): While elevated total cholesterol is a risk factor for cardiovascular disease, it is not specifically listed as a risk factor for abdominal aortic aneurysm (AAA). However, dyslipidemia, including elevated total cholesterol levels, can contribute to the development of atherosclerosis, which is a risk factor for AAA.
C. HDL cholesterol 65 mg/dL (male greater than 45 mg/dL; female greater than 55 mg/dL): High-density lipoprotein (HDL) cholesterol levels greater than 65 mg/dL are not listed as a risk factor for abdominal aortic aneurysm (AAA). However, low levels of HDL cholesterol are associated with an increased risk of cardiovascular disease, which may indirectly contribute to the development of AAA through the promotion of atherosclerosis.
D. Smoking cigarettes: Smoking cigarettes is a significant modifiable risk factor for abdominal aortic aneurysm (AAA). Smoking damages the walls of blood vessels, promotes inflammation, and accelerates the development of atherosclerosis, increasing the risk of AAA formation and rupture.
E. Family history of aneurysm: A family history of aneurysm, particularly abdominal aortic aneurysm (AAA), is a risk factor for developing AAA. Genetic factors can predispose individuals to the development of aneurysms, and a positive family history increases the likelihood of AAA occurrence.

Correct Answer is ["A","B","D","E"]
Explanation
A. Elevated erythrocyte sedimentation rate (ESR): Elevated ESR is commonly seen in inflammatory conditions such as pericarditis. ESR measures the rate at which red blood cells settle in a tube of blood over a certain period, and elevated levels indicate inflammation or tissue damage.
B. Increased C-reactive protein (CRP): CRP is an acute-phase reactant produced by the liver in response to inflammation. Elevated CRP levels are indicative of inflammation, making it a useful marker in pericarditis.
C. Elevated thyroid-stimulating hormone (TSH): Elevated TSH levels are not typically associated with pericarditis. TSH is a hormone produced by the pituitary gland that stimulates the thyroid gland to produce thyroid hormones. Elevated TSH levels are seen in conditions such as hypothyroidism.
D. Increased brain natriuretic peptide (BNP): BNP is a hormone produced by the heart in response to increased pressure and volume overload. Pericarditis can lead to increased pressure within the heart, resulting in elevated BNP levels. Therefore, increased BNP levels are anticipated in pericarditis.
E. Increased troponin I: Troponin I is a cardiac biomarker released into the bloodstream when there is damage to cardiac muscle cells. While pericarditis primarily involves inflammation of the pericardium (the sac surrounding the heart), severe cases can lead to myocardial involvement and subsequent release of troponin I. Therefore, increased troponin I levels may be observed in pericarditis, especially if there is myocardial involvement.
Correct Answer is B
Explanation
A. Myopia: Myopia refers to nearsightedness, which is caused by refractive errors in the eye and is not associated with Meniere's disease. Myopia results in difficulty seeing distant objects clearly.
B. Vertigo: Vertigo is a hallmark symptom of Meniere's disease and is caused by an excessive accumulation of endolymph fluid in the inner ear. Vertigo presents as a sensation of spinning or dizziness, often accompanied by nausea, vomiting, and imbalance.
C. Photophobia: Photophobia refers to sensitivity to light, which can be associated with various eye conditions but is not a typical manifestation of Meniere's disease. Photophobia may occur in conditions such as migraine headaches or certain eye infections.
D. Presbycusis: Presbycusis refers to age-related hearing loss, which typically occurs gradually over time and is not directly associated with Meniere's disease. Meniere's disease is characterized by sudden episodes of vertigo, hearing loss, tinnitus, and a sensation of fullness or pressure in the ear.
