Q

What is H Pylori quadruple therapy? When to use?

A

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

Q

H pylori chronic gastritis predisposes to what?

A

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)

Q

deficiency in vitamin B1

A

(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.

Q

deficiency in vitamin B12

A

(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.

— 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

Q

Characteristic urine finding for prerenal azotemia

A

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.
