65
Q

Pulmonary complications see with patient with Polymyositis?

A

patients with polymyositis can also develop a number of pulmonary complications, including interstitial lung disease (ILD), infection (due to immune suppressive therapy), drug-induced pneumonitis (eg, methotrexate pneumonitis), and respiratory muscle weakness. ILD is especially common in patients with a positive anti-Jo-1 antibody, and can be identified on high-resolution CT imaging as ground-glass opacities, reticular changes, honeycombing, or patchy consolidation. Pulmonary function tests (PFTs) should be performed to distinguish ILD from respiratory muscle weakness and will show decreased forced vital capacity, total lung capacity, and diffusing capacity. Initial management of ILD in patients with polymyositis is similar to treatment of the underlying polymyositis with systemic glucocorticoids and corticosteroid-sparing agents, but ILD may progress despite improvement in myopathic features.

71
Q

26 yo M w/low back pain x8m that has progressivly worsened. Pain is worse in the AM & improves throughout the day. Dad has back problems as well. Limited ROM of lumbosacral spine, reduced chest expansion. testing to dx? monitoring? what should you advise this pt to avoid?

A

XR sacroiliac joint to look for sacroiliitis = ankylosing spondylitis *can monitoring with repeat XR q3m or acute phase reactants like ESR *AVOID smoking! pt limited chest expansion likely to develop into restrictive lung dz with apical pulmonary fibrosis - smoking will only worsen. Also exercise improves function without worsening disease =) *no change in life expenctancy

73
Q

Sarcodosis vs Scleroderma sx?

A

*Sarcoidosis:GRUELING-CC Granulomas, rheumatoid arthritis, uveitis, erythema do some, lymphadenitis, interstitial fibrosis, negative PPD, gamma globe anemia, increase calcium, cardiac problems

*Scleroderma - systemic sclerosis/collagen deposits(anti scl-70(diffuse) & anti-centromere ab(CREST)) = CREST: Calcinosis, Raynaud phenomenon, Esophageal dysmotility, Sclerodactyly & Telangiectasias

74
Q

Best HTN medication for scleroderma induced HTN? why?

A

ACEi = Captopril (fast onset), counters ACE induced vasoconstriction causing Vasodilation efferant > afferent arteriols. can cause transient increase in Cr but long term is beneficial

75
Q

Polymyositis Sx, age range, labs? Vs hypothyroid myopathy?

A

polymyositis, including progressive, painless proximal muscle weakness with elevated muscle enzymes (eg, creatine kinase, transaminases) and inflammatory markers (eg, C-reactive protein). Polymyositis is an inflammatory myopathy triggered by unknown, possibly viral, antigens. Peak incidence occurs at age 40-50. Proximal muscle weakness typically manifests as difficulty climbing stairs, getting into or out of a low chair or car, or working with the arms overhead (eg, combing hair). Joint pain (as in this patient) or swelling may be present. Polymyositis can also involve the upper esophageal musculature, leading to dysphagia with regurgitation and aspiration. Dermatomyositis is a similar disorder, but with characteristic skin manifestations. Most patients have detectable autoantibodies (eg, antinuclear antibody, anti-Jo-1). Definitive diagnosis is established on muscle biopsy. Polymyositis and dermatomyositis may occur as paraneoplastic syndromes, so patients should undergo careful examination and age-appropriate screening tests. Hypothyroid myopathy is a common cause of muscle weakness and can be associated with creatine kinase elevation. However, it is typically also associated with myalgias, delayed reflexes, and other symptoms of hypothyroidism. This patient has an elevated TSH consistent with subclinical hypothyroidism, but his thyroxine level is normal.

76
Q

what would you see on an XR of a hand with gout?

A

normal in early disease, punched out = rat bite lesions at joints

77
Q

When should u order an XR of the spine?

A

when u suspect OM, cancer, fracture or ankylosing spondylitis or those who fail to improve with initial therapy after 2-4 weeks of conservative therapy

78
Q

A

6 weeks
