Step 2 Qbank review Flashcards
how does Crohn’s disease lead to nephrolithiasis?
Normally Oxalate is bound by calcium in the gut preventing its absorption, with Crohn’s and other fat malabsorption diseases, calcium is preferentially bound to fat. The unbound oxalate is then absorbed and leads to hyperoxaluria and oxalate stone formation.
Conditions associated with formation of calcium phosphate stones
Hyperparathyrodism and RTA
Cause and treatment of acute unilateral cervical adenitis
Typically caused by Streptococcal and staphylococcal infections. Treatment usually consist of I&D plus CLINDAMYCIN (since s. aureus produced b-lactams -MRSA- Amoxicillin is a poor choice).
Essential tremor
Essential tremor is often bilateral, affects upper extremities and worsens at the end of an activity.
Parkinson’s disease tetrad
Resting tremor, rigidity, postural instability, and bradykinesia.
Definition of chronic bronchitis.
Chronic productive (white sputum, may have some blood tinge) for 3 months in 2 successive years. Cigarette smoking is the leading cause.
Luteoma presentation
Classically presents in AA women, 30-40, during pregnancy, up to 1/3 can develop hirsutism. On U/S is appears as a multinodular solid mass on BOTH ovaries.
Painless bloody stools in well appearing neonate
Milk or soy protein proctocolitis.
Cyclical vomiting
Reccurent self limitign episodes of v/n in children in absence of other causes. Higher incidence in children of parents with + migraine hx. Tx: antiemetics and reassurance for the parents.
Unusually dark urine
conjugated hyperbilirubinemia
Light’s criteria transudative vs exudative
Any pos in LC = exudative (inflammatory process)
Causes of Dyspepsia
NSAIDs, Gastric or esophageal cancer and symptomatic H. Pylori infx
mucomycosis
Caused by fungus Rhizopus, most often in suceptible diabetics. Presents with low grade fever, dull facial pain, and bloody nasal discharge. Tx surgical debridement + IV AMPHOTERICIN.
Infective endocarditis presentation and treatment.
Present with intermittent fever, fatigue, new holosystolic murmur and pos cultures. Start with Vancomycin, it covers staph, strep and enterococci. After cultures, if PCN sensitive, treat with IV PCN-G or IV CEFTRIAXONE.
Pneumothorax presentation
tachypnea, tachycardia, DISTENDED NECK VEINS, tracheal deviation away from injury (diff in pressures)
Pneumothorax mgt
needle thoracostomy, possible chest tube and intubation
Comorbidites associated with panic disorder
Major depression, bipolar disorder, agoraphobia (fear of public spaces), and substance abuse.
Holosystolic murmurs
TR, MR, and VSD
CMV retinitis
HIV pt CD4<50, yellowish-white patches of retinal opacifications and retinal hemorrhages. Tx Valganciclovir, Ganciclovir or Forscarnet
HIV Candidal esophagitis
Oral thrush and candidal esophagitis treat with 1-2 weeks of fluconazole.
HIV esophagitis HSV
small, well circumscribed round/ovid ulcers and intranuclear inclusions. Tx: ACYCLOVIR
HIV esophagitis CMV
Large linear ulcers and intranuclear and intracytoplasmic inclusion (Owl eyes). Tx: GANCICLOVIR
5 common side effects of Amiodarone
Pulmonary fibrosis, Hypothyrodism, Hepatotoxic, Corneal deposit and Blue-gray skin discoloration
Signs of tracheobronchial injury
Hemoptysis, pneumomediastinum, and air leak even after chest tube placement.
