“In patients with classic symptoms of angina, NUCLEAR STRESS TESTING is the most widely used test for diagnosis of ischemic heart disease.”
(SmartyPance)
which arrhythmia presents as early wide BIZARRE QRS with no p wave?
PVC
(SmartyPance)
what arrhythmia presents as abnormally shaped P waves?
PAC
(SmartyPance)
what is myxedema? what does it make the pt predisposed to?
severe hypothyroidism (possibly untreated hypothyroidsim)
carpal tunnel syndrome
(“Patients with myxedema or hypothyroidism have accumulation of myxedemateous tissue under the transverse carpal ligament, which causes compression of the median nerve in the carpal tunnel resulting in the manifestations of carpal tunnel syndrome.”)
(SmartyPance)
what is the hallmark of diabetic retinopathy?
NEOVASCULARIZATION
“Neovascularization is the hallmark of proliferative diabetic retinopathy. New vessels can appear at the optic nerve and the macula as a result of retinal hypoxia. They are susceptible to rupture, resulting in vitreous hemorrhage, retinal detachment, and blindness. Proliferative retinopathy requires urgent referral to an ophthalmologist and is usually treated with pan retinal laser photocoagulation.”
(SmartyPance)
What laboratory test could lead to the earliest confirmation of B. pertussisor parapertussis infection?
Polymerase Chain Reaction assay and antigen detection
“The diagnosis of pertussis is still primarily clinical, and laboratory results only play a small role in the diagnostics. Although culture used to be the gold standard, PCR assay and antigen detection are now considered more reliable. PCR assay and antigen detection are increasingly used to assist in diagnosing pertussis.”
(SmartyPance)
what are the mainstays of treatment for ulcerative colitis?

” In addition to sulfasalazine or 5-amino-salicylacid, more severe ulcerative colitis cases require corticosteroids. Corticosteroids are also helpful in Crohn’s disease involving the small bowel. “
(SmartyPance)
describe the aortic regurgitation murmur
SOFT
EARLY DIASTOLIC
HIGH-PITCHED MURMUR
BEST HEARD SITTING/LEANING FORWARD
“aortic regurgitation, as it presents as a soft, early diastolic, high-pitched murmur heard best when sitting and leaning forward. It is often a result of rheumatic heart disease, which may be inferred by the patient’s history. “
(RoshReview)
67-year-old woman presents complaining of dark urine. Over several months she has had increased fatigue and weight loss. There has not been any fever or night sweats. On physical examination, she has scleral icterus and mild jaundice. Her abdomen is soft, non-distended with a palpable mass in the right upper quadrant that is non-tender. What imaging is required?
ABDOMINAL CT: R/O PANCREATIC CA
“The patient’s symptoms are concerning for pancreatic cancer. This patient has developed painless jaundice, the classic presentation of someone with a mass at the head of the pancreas compressing the bile duct. Patients will often also complain of weight loss typically due to loss of appetite. The imaging study of choice in this situation is an abdominal CT scan.”
(RoshReview)
“An 83-year-old man from a nursing home is sent for evaluation of abdominal distention and vomiting. Nursing home records report no bowel movement for two days and no fevers. On CT scan, no obstructing lesion is identified. What may be beneficial in relieving this condition?”
NEOSTIGMINE
“CT scan does not show any obstructing lesion and therefore this is a pseudo-obstruction, also known as Ogilvie syndrome. The exact mechanism of the development of pseudo-obstruction is unknown but suspected to result from malfunction of the autonomic control of the bowel. Patients often have multiple other co-morbid conditions and risk factors include nursing home residence, anticholinergic medication, severe electrolyte disturbance, narcotic exposure, or a history of spine or retroperitoneal trauma. This is a diagnosis of exclusion. Patients may first be treated with a rectal tube and sigmoidoscopy and managed conservatively in the hospital. Neostigmine may be used as a pharmacologic intervention as it is an acetylcholinesterase inhibitor.”
(RoshReview)
Which laboratory finding is most consistent with refeeding syndrome?
HYPOPHOSPHATEMIA HYPOKALEMIA THIAMINE DEFICIENCY CHF PERIPHERAL EDEMA Refeeding syndrome is a complication that occurs during nutritional therapy of malnourished patients.
(RoshReview)
what is alpha-1 antitrypsin (AAT) deficiency?
alpha-1 antitrypsin (AAT) deficiency is an inherited disorder that affects the lung, liver, and sometimes the skin.
Patients with severe AAT deficiency are at risk for emphysema due to an imbalance of enzymes leading to increased destruction of elastin in the lungs. Liver disease often results from the accumulation of an AAT protein in the liver. Patients with AAT deficiency often report dyspnea, cough, and a history of chronic upper respiratory infections.
(RoshReview)
what distinguishes alpha-1 antitrypsin deficiency from COPD?
Younger onset (< 45 years old), a negative smoking history, and a basilar-predominant pattern of emphysema on CXR can help distinguish AAT deficiency from COPD and acute bronchitis.
