Q

Describe the management of Dermatomyositis?

A
  • High dose glucocorticoids PLUS glucocorticoid sparing agent
  • Screening for malignancy
18
Q

Wound infections in burn patients are common, and patients with large surface area burns (>20%) are at highest risk. What is the earliest sign?

A

Change in appearance of the wound (partial thickness injury turns into a full thickness injury)

19
Q

Burn wound sepsis can develop rapidly and is associated with some or all of the following systemic findings?

A
  • Temp <36.5 (97.7) or >39 (102.2)
  • tachy (>90)
  • tachypnea (>30)
  • Refractory hypotension (systolic blood pressure < 90)
  • Oliguria, unexplained hyperglycemia, thrombocytopenia, and mental status changes are also common
20
Q

Lumbosacral radiculopathy (sciatica) is due to nerve root compression, usually by a herniated disc or lumbar spondylosis. Most patients will experience spontaneous resolution. Initial management is primarily focused on what?

A

Short term relief of symptoms with NSAIDs or acetaminophen

21
Q

Patients with RA are at increased risk of developing what?

A
  • Osteopenia
  • Osteoporosis
  • Bone fractures
22
Q

Patients with fibromyalgia have a fairly normal physical exam except for trigger point tenderness in areas such as where?

A
  • mid trap
  • lateral epicondyle
  • costochondral junction
  • greater trochanter
23
Q

correlation of pain in fibromyalgia with exercise and what can improve pain and provide long term benefit?

A
  • patients perceive that their pain and fatigue worsen acutely after exercise
  • A regular, incremental, low impact exercise regimen can improve pain and provide long term benefit
24
Q

rapid onset of hemarthrosis is associated with what knee injury

A

ACL tear

25
Q

This is due to a decrease in exocrine output from the lacrimal and salivary glands. Decreased blink rates, oxidative damage, and use of anticholinergic meds can also contribute

A

Age related sicca syndrome

26
Q

Like patellofemoral pain syndrome, this disease can cause anterior knee pain that is worse with squatting. However, it would NOT be seen in adult patients?

A

Osgood-Schlatter disease

27
Q

A young African American woman with constitutional symptoms (fatigue), thrombocytopenia, probable mitral regurg (holosystolic murmur to the apex), and a + ANA, suggestive of SLE, now likely has a CVA (sudden onset unilateral weakness, negative CSF findings) . . . likely has what?

A

Antiphospholipid syndrome

28
Q

Antiphospholipid syndrome is characterized by a thrombotic event or pregnancy morbidity in the setting of a positive autoantibody to 1 of what 3 phospholipids?

A
  • Anticardiolipin antibody
  • Anti-beta2-glycoprotein-1 antibody
  • Lupus anticoagulant
29
Q

Erythema nodosum is a condition of painful, red or violaceous, subcutaneous nodules. It can be a sign of a more serious disease process . . what test should be done?

A

-Even in the absence of respiratory symptoms, chest x-ray should be performed in patients with Erythema nodosum to assess for findings consistent with sarcoidosis

30
Q

with the elbow held in extension, passive flexion of the wrist reproduces pain . . what is diagnosis?

A

Lateral epicondylitis

31
Q

This causes posterolateral elbow pain similar to that in lateral epicondylitis and may occur in conjunction with that condition. Findings include weakness of extension at the wrist and third digit, reproduction of pain on resisted supination of the forearm, and pain at the radial tunnel on resisted hyperextension of the wrist

A

Radial tunnel syndrome

32
Q

What anti rheumatoid drug causes macrocytic anemia and why?

A

Methotrexate: inhibits dihydrofolate reductase

33
Q

Clinical features of Felty syndrome?

A
  • Rheumatoid arthritis: Severe erosive joint disease and deformity, Rheumatoid nodules, Vasculitis (mononeuritis multiplex, necrotizing skin lesions)
  • Neutropenia
  • Splenomegaly
34
Q

Whipple disease is a multisystem disorder with a varied presentation caused by infection with the gram-positive bacillus Tropheryma whippelii. What are the most common presenting symptoms?

A
  • Chronic malabsorptive diarrhea
  • weight loss
  • Migratory non-deforming arthritis
  • lymphadenopathy
  • low grade fever
35
Q

Compression of the median nerve at the wrist causes carpal tunnel syndrome, characterized by pain and paresthesias in the first 3 digits and the radial half of the 4th. The diagnosis is usually made on clinical grounds, what what can confirm the diagnosis?

A

Nerve conduction studies

36
Q

Patients with pseudogout should be evaluated for secondary causes such as what?

A
  • hyperparathyroidism
  • hypothyroidism
  • hemochromatosis
37
Q

Patients with long-standing ankylosing spondylitis can develop bone loss due to increased osteoclast activity in the setting of chronic inflammation. In addition, spinal rigidity in these patients can increase the risk of what?

A

vertebral fracture, which often results from minimal trauma

38
Q

Patients with sarcoidosis who are asymptomatic are often followed without treatment due to a high rate of spontaneous remission. However, patients with symptomatic disease (e.g. cough, dyspnea, fatigue, hypercalcemia) are treated with what?

A

-Systemic glucocorticoids

39
Q

Treatment of Paget Disease of Bone

A

Bisphosphonates

40
Q

What is a well known complication of Giant cell arteritis and how do you follow this?
