24

Acute diffuse encephalomyelitis

a diffuse autoimmune demyelination process that typically follows a viral infection or antiviral vaccination.

It produces multiple inflammatory lesions in the brain and spinal cord, particularly in the white matter.

ADEM causes signs and symptoms of demyelination with encephalopathy, acute hemiparesis, cerebellar ataxia, cranial neuropathies, and spinal cord dysfunction.

25

RX for choreiform mvmts of huntingtons

Excess dopamine is responsible for the involuntary movements. Dopamine receptor blockers, such as haloperidol, olanzapine, risperidone, and aripiprazole are thus good choices to control these movements.

Hypothyroidism effects on cardiovascular

results in hypertension and hypercholesterolemia.
When treated, blood pressure, serum LDL, and serum triglycerides all decrease.

58

best test for finding pheochromocytoma

The most sensitive test for the diagnosis of pheochromocytoma is plasma free fractionated metanephrines.

Remember the key symptoms for the diagnosis of pheochromocytoma: paroxysmal hypertension, tachycardia, and diaphoresis.

59

Elderly women with new-onset ascites

should be investigated to rule out ovarian malignancy. (peritoneal carcinomatosis)

Constrictive pericarditis pressures

presents with equal diastolic pressures for all cardiac chambers
Pericardial calcifications are a key imaging finding
Symptoms show right-sided heart failure, including the Kussmaul sign

61

Postoperative ileus

nonmechanical obstruction of the small bowel. It is secondary to extensive manipulation of the bowel and is contributed to by narcotic use and electrolyte imbalances.
Diagnosis is made on clinical grounds with the aid of x-ray and/or CT scan.
Management consists of nothing-by-mouth (NPO) and nasogastric tube placement.

62

metastatic pancreatic cancer, what do we do?

chemotherapy, not surgery

63

treatment of UC

the mainstay of outpatient management of mild ulcerative colitis is topical anti-inflammatory therapy with 5-ASA preparations such as mesalamine, olsalazine, and balsalazide.

64

decrease in hemoglobin during the course of erythropoietin therapy in a patient who has CRF signifies one of the following:

Presence of an underlying infection
Aluminum toxicity
Depleted iron stores
Hyperparathyroidism
Management includes stopping the erythropoietin, treating the anemia with transfusion, and addressing the underlying cause.

65

most likely complication in pancreatitis?

Adult respiratory distress syndrome (ARDS) is a life-threatening complication of acute pancreatitis caused by release of phospholipase, which circulates through the bloodstream and damages the alveolar capillary membranes in the lungs.

66

achalasia cause

loss of normal inhibitory neurons in the lower esophageal sphincter (LES).

67

postprandial abdominal discomfort and bloody diarrhea in elderly patients.

Ischemic colitis

68

Acute angle-closure glaucoma

is a medical emergency in which the iris is pushed or pulled up against the trabecular meshwork at the angle of the anterior chamber of the eye, causing a block in the normal outflow of aqueous humor, thereby increasing the intraocular pressure.

69

anti-U1-RNP antibodies

Mixed connective tissue disease (MCTD) classically is associated with anti-U1-RNP antibodies
Initial presentation may be Raynaud phenomenon or dyspnea due to pleural effusion
This is a diagnosis of exclusion so make sure to evaluate for other autoantibodies

70

how does sarcoidosis increase calcium?

Granulomatous lesions produce hypercalcemia by increasing the production of vitamin D, which promotes calcium uptake from the duodenum.

71

mutations and their diseases
CDKN2A
p53
RET
TSC
PTCH

Melanoma is associated with CDKN2A mutation (tumor suppressor gene).
p53 mutation = Li-Fraumeni syndrome.
RET mutation = MEN 2A/2B.
TSC mutation = tuberous sclerosis.
PTCH mutation = Gorlin syndrome. (basal cell nevus)

72

Chest pain precipitated by hot or cold liquids without other obvious pathology

is most likely the result of diffuse esophageal spasm.
The best diagnostic test is esophageal manometry testing, which will reveal uncoordinated peristalsis in the esophagus.
Endoscopy is usually normal and does not aid in the diagnosis of peristaltic disorders.

73

Autoimmune hepatitis

chronic hepatitis of unknown etiology characterized by hypergammaglobulinemia and a positive ANA and ASMA.
Corticosteroids are the mainstay of anti-inflammatory/immunosuppressive therapy in autoimmune hepatitis.

74

Whipple disease

A combination of diarrhea, arthralgias, endocarditis, and central nervous system dysfunction should prompt consideration of Whipple disease, which is treated with antibiotics.
PCR is diagnostic; PAS-positive macrophages in the lamina propria are associated

75

Sudden hemodynamic compromise (in ventilated patients, shortly after adding or increasing PEEP)
Distended neck veins
Jugular venous pulsations
Absent breath sounds on one side

suspect tension pneumothorax

76

The outpatient management of recurrent calcium oxalate stones includes:

24-hour urine testing for calcium, phosphate, oxalate, and uric acid
Oral hydration
Hydrochlorothiazide to reduce tubular calcium concentration

77

Diastolic dysfunction

impaired ventricular filling during diastole.
The most common cause of diastolic dysfunction is chronic hypertension leading to left ventricular hypertrophy.

78

amiodarone and warfarin

amiodarone inhibits warfarin metabolism, decrease the warfarin dose!

79

A patient presenting with a history of eye pain, blurry vision, and red eye with signs of increased intraocular pressure in the setting of juvenile rheumatoid arthritis points toward the diagnosis of

anterior uveitis.

Patients presenting with glaucoma usually have extreme pain and blurred vision, see halos around lights, and have nausea and abdominal pain. On examination, there is chemosis, the cornea is described as steamy, and the pupil is moderately dilated and nonreactive. Intraocular pressure is significantly elevated. Secondary acute angle closure is seen with anterior uveitis (iridocyclitis), dislocation of the lens, or topiramate therapy. In this question the patient has ANA-positive JRA, which is associated with anterior uveitis and is the reason for her secondary acute angle-closure glaucoma.

80

Valvular lesions are most accurately assessed with

catheterization/angiography.

81

what metastasizes to the bone?

Carcinomas of the breast, prostate, and lung are the most common tumors that metastasize to bone.

82

Multiple endocrine neoplasia IIa (MEN IIa):

Pheochromocytoma, medullary thyroid carcinoma and hyperparathyroidism
Autosomal dominant, associated with mutations in the RET proto-oncogene

83

when to treat external hemorrhoids

Best time to treat thrombosed external hemorrhoids = first 3 days of symptoms.

After 3 days, pain from the procedure will last longer than the pain from the disease.

Rubber band ligation is only used in the treatment of internal hemorrhoids.

84

Chronic atrophic gastritis caused by pernicious anemia is associated with

markedly elevated serum gastrin levels, because normal acid inhibition of G cells is lost.

Suspect pernicious anemia in a patient who has vitamin B12 deficiency, atrophic gastritis, and peripheral neuropathy.

85

The acid-base disturbances

pulmonary embolism, acute asthma, and chest trauma acute respiratory alkalosis with hypoxemia (high pH, low pCO2, and low pO2).

Chronic obstructive lung disease and sedative overdose can cause respiratory acidosis with low pH, high pCO2, and low pO2.

Renal failure and sepsis cause metabolic acidosis,

aspirin overdose causes metabolic acidosis with respiratory alkalosis.

86

RX for hypertension and BPH together?

terazosin

87

Plummer-Vinson syndrome i

dysphagia, upper esophageal webs, atrophic glossitis, and severe iron-deficiency anemia.
Other manifestations of severe iron-deficiency anemia include koilonychias, angular cheilitis, and pica.

88

Treatment of keloids

intralesional steroid injection.

89

Crohn's disease and bleeding

Vitamin K deficiency

90

DKA, what do we use to guide conversion from IV insulin to subcutaneous insulin.

anion gap

91

Symptoms of opiate overdose are

severe respiratory depression, nausea, vomiting, miosis (constriction), and CNS depression.
Treatment is supportive, with naloxone to reverse symptoms.

92

melanis coli

Chronic laxative abuse can lead to melanosis coli, a benign diffuse or patchy pigmentation of the colonic mucosa that presents on pathology as lipofuscin-laden macrophages.
This condition is benign and does not require intervention.

93

sickle cell and gallstones

Sickle cell disease commonly causes cholelithiasis, specifically black pigment stones
Sickle cell disease causes splenic autoinfarction and H-shaped vertebrae

94

pancreatic abcess timing

10-14 days after pancreatitis
fever and leukocytosis

as opposed to pancreatic pseudocyst, 6 weeks later and w/o fever/ leukocytosis

95

common bile duct (CBD) strictures

80% of common bile duct (CBD) strictures occur after injury during a laparoscopic or open cholecystectomy.
Strictured ducts are more prone to obstruction and secondary infection (cholangitis).
Cholangitis, which can rapidly become life-threatening, presents with the Charcot triad.

96

dx of PE

CT angiogram

sometimes V/Q scan (patients who cannot tolerate the load of intravenous contrast necessary for an angiogram due to allergy or impaired renal function.)

97

right ventricular infarct vs cardiac tamponade

The clinical signs of cardiac tamponade are exactly the same as a right ventricular infarct. However, there is one clinical sign that differentiates the two: the presence or absence of pulsus paradoxus.

98

high dose steroid risk

Steroid use is a risk factor for the development of a gastric ulcer, and all patients on steroids should be put on antihistamine blockers or proton-pump inhibitors as prophylaxis.
Suspicion for an ulcer in a patient with pneumoperitoneum indicates perforation and mandates urgent surgical exploration.

99

Pringle maneuver

clamping the portal triad (hepatic artery, portal vein, and CBD). Temporarily, will stop the blood flow if the injury includes vessels in the hepatoduodenal ligament.
If blood flow continues even after the Pringle maneuver, the vessel that is most likely injured is a hepatic vein or the inferior vena cava behind the liver.

100

things that put AST/ ALT in the thousands

acetominophen OD
hepatitis (acute viral or autoimmune)
aflatoxin (death cap mushroom)
budd chiari
shock liver

101

pancreatic pseudocyst rules

6 cm, 6 weeks. Either of these warrants intervention.

102

graft vs host disease is mediated by

T cells

103

what to do with skin cancers

Skin cancers should be biopsied prior to definitive management.
Biopsies should be full thickness and from the periphery of the lesion to assess the interface with normal skin.
Basal cell carcinoma requires minimal surgical margin, compared to melanoma which requires wider margin and lymph node dissection.

104

Progressive dysphagia from solids to liquids is

esophageal cancer until proven otherwise.
Smoking and drinking are strong risk factors for the development of squamous cell carcinoma of the esophagus.
Longstanding GERD and Barrett esophagus are associated with adenocarcinoma.

105

Cushing triad:

Increased intracranial pressure caused by intracerebral hemorrhage is evident from the presence of Cushing triad: bradycardia, hypertension, and irregular respiratory patterns.
It is diagnosed clinically, with CT scan or with direct measurement by intracranial pressure monitor insertion.
Management encompasses various strategies to decrease intracranial pressure, including raising the head of the bed, sedation, mechanical ventilation, hyperventilation, administration of mannitol, and surgical decompression with a Burr hole or craniotomy.

106

major risk of AAA repair

Ischemic colitis is a known complication of abdominal aortic aneurysm (AAA) repair secondary to occlusion of the inferior mesenteric artery.
Prompt recognition and diagnosis with colonoscopy allows for timely resection of the colon with a colostomy to prevent sepsis and death.

107

what to do with post op patient with fever

most common source on the first day is atelectasis. Treatment requires that ventilation be improved, via deep breathing, coughing, and incentive spirometry use to expand the lung. In severe cases, positive pressure can be used to provide alveolar recruitment and improve oxygenation.
