COMBANK IM COMAT Flashcards
H Pylori treatment
triple therapy: PPI (omeprazole), clarithromycin, and amoxicillin
— twice daily dosing
O-CLAM
What is H Pylori quadruple therapy? When to use?
Quadruple therapy is less preferred and is currently used if there is recurrence.
It consists of omeprazole 20 mg twice daily, bismuth subsalicylate 2 tabs four times daily, tetracycline 500 mg four times daily, and metronidazole 500 mg three times daily
H pylori chronic gastritis predisposes to what?
MALT Lymphoma (MALTomas)
Pathophys:
- accumulation of CD4+ lymphocytes and mature B cells in the gastric lamina propria in H pylori-induced gastritis.
- antigens produced from H. pylori activate T and B cell proliferation, and lymphoid follicle formation
- If this is persistent if can become a monoclonal lymphoma (B cells)
deficiency in vitamin B3
(niacin)
Pellagra
4 D’s: dermatitis, diarrhea, dementia, and death
— (photosensitive pigmented dermatitis in sun exposed areas)
deficiency in vitamin B1
(thiamine)
Wernicke-Korsakoff syndrome
- – Wernicke’s encephalopathy is manifested by necrosis of the mammillary bodies in the periventricular region of the brain. Symptoms include progressive dementia, confusion, ataxia, and paralysis of the extraocular muscles. This causes ophthalmoplegia of the bilateral lateral rectus muscles, which results in a sixth nerve palsy.
- – Korsakoff psychosis is a thought disorder that results in retrograde memory failure and confabulation. The most common causes of thiamine deficiency include poor diet and chronic alcoholism.
deficiency in vitamin B12
(cobalamin)
subacute combined degeneration
— of the dorsal and lateral spinal columns due to a defect in myelin formation. Peripheral neuropathy can result, which is SYMMETRICAL in nature and affects the LEGS more than the arms. It manifests with paresthesias, ataxia, and loss of vibration and position sense.
who gets vit B12 deficiency
Get Cobalamin (vit b12) from animal products so think of this in vegans or due to inadequate absorption associated with pernicious anemia or Crohn’s disease
deficiency of vitamin B2
(riboflavin)
cheilosis or angular stomatitis (scaling lips with fissures), and glossitis.
— cracked and red lips, inflammation of the tongue, mouth ulcers, cracks at the corners of the mouth, and a sore throat.
may also cause dry and scaling skin, fluid accumulation in the mucous membranes of the mouth, and an iron-deficiency anemia. The eyes may also become sensitive to bright light. Additionally, patients may develop seborrheic dermatitis on the face or genitalia
who gets vit B2 deficiency
patients with anorexia nervosa or with malabsorptive syndromes such as celiac sprue.
deficiency in vitamin B6
(pyridoxine)
stomatitis, glossitis, cheilosis, irritability, confusion, and depression
— inflammation and fissuring of the lips, cheilosis occurring at the corners of the mouth, atrophy of the mucosa of the tongue, and seborrheic dermatitis.
can also lead to polyneuropathy in adults. Also microcytic, hypochromic sideroblastic anemia with the presence of basophilic stippling seen on a peripheral blood smear.
who gets vit B6 deficiency
pregnancy or therapy with certain medications, such as the anti-tuberculosis drug isoniazid.
Another common cause of vitamin B6 deficiency is chronic alcoholism.
vit B2 vs vit B6 deficiency
both can have cheilosis or stomatitis
- B6 has irritability/confusion and polyneuropathy
- anemias are different:
- – B2 is IDA
- – B6 is microcytic hypochromic sideroblastic anemia
long term management of Afib
rate control + anti-coagulation tx
- – rate: Ca channel blocker or B-blocker
- – anti-coag based on CHADS2VASC
When to do electrical cardioversion for Afib
Afib with RVR in hemodynamically unstable pts or for new-onset Afib of <48hrs
acid-base status in DKA
high anion gap metabolic acidosis (with respiratory compensation)
what to watch out for in pt on aldosterone antagonist and ACEi or ARB
hyperkalemia
HCTZ common side effects
hypercalcemia hyperuricemia hyperglycemia hypokalemia hyponatremia hypomagnesemia
Carvedilol common side effects
bradycardia heart block hyperglycemia weight gain impotence
Enalapril common side effects
hyperkalemia
renal insufficiency
cough
angioedema
Spironolactone common side effects
hyperkalemia
gynecomastia
renal insufficiency
Aspirin common side effects
tinnitus
bleeding
interstitial nephritis
manifestations, causes, and corrections of every electrolyte disturbance
**look up****
Electrocardiogram shows a wandering baseline and irregular complexes with a faint pulse
V fib
- characterized by irregular, random waveform with no discernible p waves or QRS complexes
atrial fibrillation rate
> 400/min
atrial flutter rate
typically ~300bpm
electrocardiogram remarkable for varying R-R intervals and a wavy baseline
A fib
best way to differentiate A fib from A flutter
A flutter has clear presence of p waves in a regular rhythm
main causes of atrial flutter
rheumatic heart disease (mitral valve involvement), chronic obstructive pulmonary disease, pericarditis and atrial septal defect
F waves on EKG
correspond to the sawtooth pattern of atrial flutter and are best appreciated in leads II, III, and aVF
Wolff-Parkinson-White (WPW) EKG
- narrow complex tachycardia with a short PR interval and a delta wave.
- delta wave is pathognomonic
- – early depolarization of the ventricle
Clinical manifestations of WPW syndrome
sudden onset of tachycardia, rapid pulse and fatigue
Selenium deficiency dz & sx
Keshan disease
presents as congestive cardiomyopathy with an enlarged heart in children and young female living in endemic areas with low soil concentration of selenium
where do you see Selenium deficiency
some parts of China, New Zealand and Finland
foods rich in selenium
fish, shellfish and eggs.
Dry beriberi
symmetrical peripheral neuropathy with both motor and sensory impairment
Wet beriberi
(in addition to neuropathy) signs consistent with CHF including cardiomegaly, lower extremity swelling, and tachycardia.
Acute calcium deficiency sx
various manifestations of neuromuscular dysfunction including peri-oral numbness, paresthesias, muscle spasms, muscle cramps and seizures
foods rich in Zinc
oysters, beef, crabs and cereal.
where are zinc deficiencies seen
middle eastern countries
mild zinc deficiency
decrease taste sensation (hypogeusia), night blindness, and decreased spermatogenesis.
severe zinc deficiency
diarrhea, alopecia, pustular dermatitis, and decreased immunity with frequent infections
chronic zinc deficiency
stunted growth in children with hypopigmented hair
presentation of pulmonary embolism on ECG
- most commonly sinus tachycardia
- right-axis deviation
- a S1Q3T3 (S wave in lead I, lead III with a Q wave and inverted T wave) pattern can also be noted as well
pulmonary popcorn-like calcification
pulmonary hamartoma
– typically benign
first step in tx acute COPD exacerbation
causes respiratory acidosis so correct the hypercapnia first. This will resolve the other common sx (hypoxia, tachycardia, dyspnea).
“serious six” of acute chest pain in ER
acute coronary syndrome pericarditis with acute tamponade aortic dissection pulmonary embolus pneumothorax esophageal rupture
gold standard for dx PE
pulmonary angiography
– really only used in hemodynamically unstable or high clinical pretest probability w/ equivocal noninvasive test findings (contrast CT)
when to do aortic valve replacement
patient presenting with symptoms consistent with aortic stenosis (chest pain, exertional dyspnea, and syncope) and having a valve area of less than 1 cm2
- otherwise medical
HCM murmur characteristics
systolic murmur
heard best over the left sternal border
murmur improves with squatting
Characteristic urine finding for prerenal azotemia
hyponatremia:
Prerenal acute renal failure stimulates release of aldosterone which leads to resorption of sodium from the collecting ducts. This will cause a fall in urine sodium to < 20 mOsm/L and fractional excretion of sodium to 1% or less. The urine becomes more concentrated than plasma.
what does a urine creatinine: plasma creatinine ratio of < 20 indicate?
intrarenal cause
– >20 in prerenal, postrenal, and acute glomerulonephritis
most likely electrolyte abnormality in DKA
HYPONATREMIA
- via plasma dilution of [Na+]
Note: likely to also have hypokalemia due to urinary losses (note that insulin may cause severe hypokalemia)
best test for overt type II diabetes mellitus
fasting plasma glucose,
as hemoglobin A1C can have approximately a 20% false negative in the screening setting.
common causes of peptic ulcer disease
Helicobacter pylori, NSAIDs, elevated acid secreting states, and Crohn’s disease.
most common cause of splenic vein thrombosis
chronic pancreatitis
Chronic somatic dysfunction
thin, smooth, dry, ropy/stringy.
Acute somatic dysfunction i
boggy and rough with lasting erythema.
