Plus any TWO of the following four factors:
TG level: ≥ 1.7 mmol/L
HDL-C - Men < 1.0 mmol/L, Women <1.3 mmol/L
Blood Pressure ≥ 130/85 mmHg
Fasting Blood Glucose ≥ 5.6 mmol/L
When to start screening full fasting lipid profile? How often?

When do you initiate treatment and what are the primary targets of treatment based on patient's 10 year risk category?
High risk (>20% 10-yr risk of CAD or Hx of DM or any atherosclerotic disease): consider treatment in all patients, LDL-C target < 2 mmol/L or > 50% decrease

Moderate risk (11-19%): treat if LDL-C > 3.5 mmol/L or TC/HDL-C ratio > 5.0, LDL-C target < 2.0 mmol/L or > 50% decrease

Low risk ( ≤10%): treat if LDL-C ≥ 5.0 mmol/L, target of ≥50% decrease in LDL-C

Lesions that exhibit any of the ABCDE signs should be excised.
What are the characteristic features of basal cell carcinoma? What is the primary treatment?
Basal cell carcinomas are the most common of all cancers. They typically appear as pearly papules, often with a central ulceration or with multiple telangiectasias. Patients typically present with a growing lesion and some- times complain that it bleeds or itches. The primary treatment is excision.

What is the most common cause of non iatrogenic hyperthyroidism? What is the pathophysiology of this disorder? What is the primary treatment?
Graves disease is an autoimmune disorder caused by antibodies directed against the TSH receptor on the thyroid gland initiating the production and release of thyroid hormone. Graves disease is treated symptomatically with antithyroid drugs (propylthiouracil and methimazole) and/or β-blockers. Definitive treatment is radioactive iodine.
What is thyroid storm?
Thyroid storm is an acute hypermetabolic state associated with the sudden release of large amounts of thyroid hormone into circulation, leading to autonomic instability and central nervous system dysfunction such as altered mental status, coma, or seizures.
What percent of Graves patients have exophthalmos?
Approximately 50% of patients with Graves disease have exophthalmos.
What is the preferred treatment of Graves disease in adolescents?
Antithyroid drugs are the preferred treatment of adolescents because they may go into spontaneous remission after 6 to 18 months of therapy.
How do you treat thyroid storm?
Thyroid storm is treated with administration of high doses of PTU and β-blockers (to control tachycardia and other peripheral symptoms of thyrotoxicosis). Hydrocortisone is given to prevent possible adrenal crisis.
What is the most common noniatrogenic cause of hypothyroidism?
The most common noniatrogenic condition causing hypothyroidism is Hashimoto thyroiditis, an autoimmune thyroiditis.
What investigations should be performed when the diagnosis of primary hypothyroid is made if the thyroid is normal on physical exam?
Once the diagnosis of primary hypothyroidism is made, further imaging or serologic testing is unnecessary if the thyroid gland is normal on physical examination.
What is the treatment of hypothyroidism?
Most healthy adults with hypothyroidism require about 1.7 μg/kg of thyroid hormone replacement daily, with requirements falling to about 1 μg/kg for the elderly. Dose is increased slowly every 4-6 weeks until TSH normalizes.
Which thyroid nodules require biopsy?
Nonfunctioning nodules measuring greater than 1 cm by examination or ultrasonography require biopsy via fine-needle aspiration.
What are signs that could confirm the rupture of membranes?
Visualization of amniotic fluid leaking from the cervix; the presence of pooling of amniotic fluid in the posterior vaginal fornix; demonstration of a pH above 6.5 in fluid collected from the vagina using Nitrazine paper; or visualization of “ferning” on a sample of fluid on an air-dried microscope slide.

What factors effect the progression of labour?
Power, passenger, passage.
What are the important considerations when interpreting fetal heart rate data?
Base-line heart rate - 110 to 160 beats/min is considered normal.
Variability - is regulated by the balance of sympathetic and parasympathetic control of the sinoatrial node. Fetal acidemia secondary to hypoxemia can impair CNS function and reduce variability.
Periodic heart rate changes - the accelerations and decelerations from the baseline heart rate that occur, often related to uterine contractions. An acceleration is an increase in the fetal heart rate of 15 beats/min or more for 15 seconds or longer and is a reassuring finding.
What is the significane of early, late, and variable decelerations in fetal heart rate?
Early - fetal heart rate decline coincides with a contraction onset. Fast return to baseline. Thought to be due to compression of fetal head (increased vagal tone).
Late - gradual reduction in the fetal heart rate that starts at or after the peak of a contraction and has a gradual return to the base-line. Late decelerations are a manifestation of uteroplacental insufficiency and fetal hypoxia.
Variable - abrupt decrease in fetal heart rate, usually followed by an abrupt return to baseline that occurs variably in its timing, relative to a contraction. Are considered to be due to umbilical cord compression during contractions.
Using an anatomical approach what are the big 3 causes of hypercalcemia.
Increase in calcium resorption from bone, decreased renal excretion of calcium, or an increase in calcium absorption from the gastrointestinal tract.
What physical symptoms are associated with hypercalcemia?
"Stones, bones, psychic groans, abdominal moans"
Also shortened QT interval and arrhythmias.
What is the first step in investigating hypercalcemia?
Rule out offending medications (eg. thiazide or lithium).
Measure serum PTH level. If elevated suspect a benign adenoma of one of the parathyroid glands. If low suspect PTH-rP and search for malignancy.

Presbycusis (#1, aged related, sensorineural), noise-induced hearing loss, cerumen impaction, otosclerosis, and central auditory processing disorder
What factors contribute to falls in the elderly?
Age related postural changes, alterations in visual ability, certain medications, and diseases affecting muscle strength and coordination.
Describe a rapid screen for dementia
“Clock draw” and the “three-item recall” is a rapid and fairly reliable office-based screening for dementia. When patients fail either of these screening tests, further test- ing with the MMSE should be performed.
Describe a rapid screen for geriatric depression
A simple two-question screen:

Findings frequently associated with GAS infections include an abrupt onset of sore throat and fever, tonsillar and/or palatal petechiae, tender cervical adenopathy, and absence of cough.
How is the diagnosis of GAS pharyngitis made? How are these results interpreted?
GAS is diagnosed via rapid antigen testing or throat culture. Rapid antigen tests can be conducted in a few minutes. RA tests are highly specific but have a lower sensitivity than throat culture. A positive rapid antigen test would prompt antibiotic treatment; a negative test should be followed by a throat culture.
