Step 3 - Rheum
Rheumatology Subsection of Step 3 Questions
| Question | Answer |
|---|---|
| Diagnosis of Lupus - PE, CBC, etc | Skin changes (malar rash, solar rash, oral ulcers, discoid); Arhtralgia - 90% of SLE patients; Serositis- Pericarditis, pleuritic chest pain, pul HTN, PNA, myocarditis |
| Change in complement levels during SLE flare | Complements drop |
| SLE and pregnancy with Anti-Ro. Most Likely fetal problem? | Heart Block |
| Treatment of SLE - Acute flare | Prednisone (steroids) |
| SLE flare that re-flares after stopping steroids? | Give blimumab, Azathioprine, cyclophosphamide |
| CCS: Patient comes in with SLE. What do you order? | Complement Levels, ANA, Anti-DSdna; Always. |
| Lupus Nephritis Treatment | Steroids + Mycophenolate |
| Drugs a/w Drug-induced Lupus | Hydralazine, Procainamide, INH. |
| Diagnose drug-induced lupus: pertinent positives and negatives | Antihistone Ab, Or Positive ANA. NEVER has Renal or CNS. Always has normal complements and normal DSdna. |
| Early Loss of teeth or lots of cavities | Sjogren's Syndrome (poor saliva) |
| Diagnose Sjogren | Lip Biopsy |
| Serology of Sjogren's - 4 types | Anti-Ro (SSA) Anti- La (SSB) Ro and La are highly specific but not so sensitive ANA is 90% sensitive RF is also present (70% sensitive) |
| Sjogren's - Presentation | "Sicca Syndrome" Dry mouth, dry eyes, "sand under the eyelid" |
| Anti SSA, Anti SSB | AKA Anti Ro, Anti La. Specific for Sjogren. Also can be seen in ANA-negative lupus |
| Scleroderma - Clinical Presentation | Woman, Tight Skin, Raynaud, Joint Pain |
| Lung Manifestations of diffuse scleroderma | Pulmonary Fibrosis, Pulmonary HTN (leading cause of death for scleroderma) |
| GI Manifestations of diffuse scleroderma | Barrett's, diverticulosis, primary biliary cirrhosis |
| Cardiac Manifestations of diffuse scleroderma | Restrictive cardiomyopathy |
| Treating renal involvement and HTN of scleroderma | ACE inhibitors |
| Treating pulmonary HTN a/w scleroderma | bosentan (endothelin antagonist) Prostacyclin analogs sildenafil |
| Preventing Raynaud's | calcium channel blocker |
| Treating lung fibrosis a/w scleroderma | cyclophosphamide |
| CREST Syndrome: Findings (positives and negatives) | Calcinosis of the fingers Raynaud's Esophageal dysmotility Sclerodactyly Telangectasia Pertinent negatives: No joint pain No heart involvement No lung involvement No kidney involvement |
| Serology a/w CREST | + anti-centromere Ab Never has Anti-Scl70 |
| Raynaud's Phenomenon | White -> blue -> red (+/- digital ulceration as a sequela) |
| Diagnosis of Lupus: Serological | ANA, Anti DSdna |
| Diagnosis of Lupus: CBC Findings | Low WBC, PLT, or hemolysis |
| Eosinophillic Fasciitis | thick skin, orange peel appearance, eosinophillia. does not have raynaud's, heart, lung, or kidney involvement. |
| Polymyositis: presentation | Patient that can't get up from seated position. Muscle pain and tenderness. |
| Polymyositis/Dermatomyositis common physical exam findings | Prox muscle weakness |
| Labs a/w polymyositis | Muscle inflammation: Elevated CPK, Aldolase |
| Difference b/w polymyositis and dermatomyositis | Skin Rashes: Grotton's papules (over MCP jt), Heliotrope rash (purple, over periorbital), Shawl Sign (shoulder and neck erythema). |
| Definitive diagnosis of polymyositis or dermatomyositis | Need a biopsy |
| Anti-Jo in polymyositis | Risk of interstitial lung disease |
| Most common serious complication of dermatomyositis | High association with cancer |
| Treatment options for fibromyalgia | Milnacipran (SNRI), Duloxetine (SNRI), pregabalin |
| Polymyalgia Rheumatica | age 50+, Proximal muscle pain and AM stiffness, elevated ESR. Has normal CPK, EMG, Alsolase, muscle biopsy, no muscle atrophy. |
