If u have dermatomyositis (DM) patient and started on steroids but weakness worsening What could be the cause?
Medication
- Steroid induced myopathy
- Dose of steroids not sufficient
Disease
- Wrong diagnosis
- 10% of PM non responsive to steroids
- Myositis worsening
Patient
- Disuse atrophy
List 6 Lab tests for dermatomyositis (DM).
- CK
- Aldolase.
- AST/ALT.
- LDH.
- ESR/CRP.
- CBC.
- urinalysis, stool specimens, CT C/A/P or other malignancy screen.
- Antibodies. a. anti-MI2 – specific for DM. b. ANA – 24-60% of pts with DM. c. anti-Jo1 – poor prognostic factor for interstitial lung disease.

List the five criteria for diagnosis of Polymyositis
- Symmetrical muscle weakness

Describe an appropriate exercise program for patients with polymyositis/SLE
STRETCHING
- To maintain ROM chronic and stable, active disease.
AEROBIC EXERCISE
- Low-level aerobic program on a cycle or in a pool
STRENGTH EXERICS
- Three-times-a-week or even daily isometric program consisting of 6-10 isometric contractions. each held for 6 sec, with a 20-sec recovery time between contractions.
- The main muscles to exercise are the deltoids, biceps, hip abductors, extensors, and quadriceps muscles
- Those patients who also have some distal weakness (20-40%) may wish to exercise wrist and hand muscles and ankle dorsiflexors/plantar flexors.
- A few studies support isotonic resistive exercise for myositis with low 1-2 lb weight two to three times a week.
PRECAUTIONS
- Increased muscle weakness and soreness
- Significant rises in CPK.
PMR Secrets 3rd Edition Chapter 68 Rheumatology pg593-594
How can you stabilize the knee in the presence of a very weak quadriceps mechanism?
- Patients with polymyositis often develop very weak quadriceps muscles and begin to fall when their strength is 3 out of 5 or below.
- Ground reaction force AFO
- Do not put a dorsiflexion assist on a brace when the quadriceps is weak. A flexion moment will be created at the knee and make it less stable.

What is Mixed connective tissue disorders (MCTDs)?
💡 They are RF (+) and ANA (+)
Disorders with characteristics of several other diseases, in particular
- SLE
- Scleroderma
- Polymyositis

- Bi-basilar pulmonary fibrosis.
≥3/5 Features of CREST syndrome:
- Calcinosis
- Raynauds
- Esophageal dysfunction
- Sclerodactyly

Answer
Jaccoud’s Arthritis
- Nonerosive deforming arthritis
- Ulnar deviation of the fingers and subluxations
- Reversible early, but may become fixed

List 4 Criteria for primary Raynaud’s disease
- Symmetric intermittent raynaud’s phenomenon attacks.
- PVD: no evidence of peripheral vascular disease.
- Gangrene: no evidence of tissue gangrene or digital pitting.
- No abnormal nailfold capillary microscopy (normal capillaroscopy).
- Negative ANA; normal ESR.
Ref: Current dx and treatment in rheumatology textbook pg 358. Memory aid: criteria are a bunch of ‘negatives’.
List 4 Causes and treatment for Raynaud’s Phenomenon 🔑
💡 Present in 90% of patients with scleroderma
CAUSES
- Skin: SLE, RA, Scleroderma, Dermatomyositis/ polymyositis
- Vessels: Vasculitis
- Blood flow: Drugs - beta-blockers, Polycythemia, TOS, Hypothyroidism
- Neurologic: SCI, CVA
- Obstruction: Trauma
- Oxygenation: Pulmonary hypertension
TREATMENT
- Avoid triggers—cold, smoking
- Keep extremity warm
- Calcium channel blockers—nifedipine
- EMG and biofeedback—self-regulation

Temporal Arteritis: Presentation - Association - Treatment 🔑
Temporal Arteritis
- Giant cell arteritis (GCA) → Involves large arteries
Presentation
- Tenderness of the scalp and in the muscle of mastication
- Headaches
- Abrupt visual loss in 15% of patients
- Associated with polymyalgia rheumatica
Diagnosis
- Elevated ESR
- Temporal artery biopsy
Treatment
- High-dose steroids ASAP imperative to preventing permanent vision loss
- ASA (325 mg daily—improves prognosis)

Explain Polymyalgia Rheumatica, Presentation, DDx, Diagnosis & Treatment
Polymyalgia Rheumatica
- Systemic inflammatory syndrome (Synovitis of the hips and shoulders)
- Associated with frequent constitutional symptoms
Theories
- Synovitis of the hips and shoulders
- Tenosynovitis (biceps)
- Bursitis (subdeltoid, subacromial, trochanteric, and interspinous muscles)
Presentation
- Patient age ≥50 years
- Systemic:
- Fever, weight loss, malaise
- MSK
- Morning stiffness for >45 minutes (neck, shoulders, pelvic girdle)
- Abrupt myalgias/arthralgia
- Hallmark—difficulty abducting shoulders above 90°
- Bilateral aching involving the shoulder girdle for ≥2 weeks
- Capsular contracture of the shoulder (limiting passive motion) and muscle atrophy
- Bilateral hip pain or a limited range of motion
- Pain at night is common and may wake the patient
- Normal strength.
Lab
- ESR >50
- Normal CK.
- Negative RF and ANA.
Differentials
- Shoulder OA, rotator cuff, frozen shoulder: Physical examination, x-rays, normal ESR
- Fibromyalgia syndrome: Tender points, normal ESR
- Rheumatoid arthritis: RF (+), small joint involvement, MTPs
- Myopathy: Polymyositis (↑ Weakness, elevated creatine kinase, abnormal EMG)
- Hypothyroidism: Elevated TSH, normal ESR
Treatment
- Prednisone at a dose of 15 to 20 mg/day (few days to be maximally effective)
