Musculoskeletal Disorders

QuestionAnswer
4 Metabolic Disorders of Musculoskeletal Osteoporosis, Paget’s Disease, Gout, Osteomalacia
Osteoporosis Risk Factors Remember ACCESS: alcohol, corticosteroids, calcium deficiency, estrogen low, smoking, and sedentary lifestyle. Age, Genetic predisposition, Female gender, Race: White or Asian, Endocrine disorders, Malabsorption disorders, Medications.
Osteoporosis Manifestations Loss of height, Progressive curvature of the spine, Low back pain, Fractures of forearm, hip, and spine, Dowager’s hump.
Osteoporosis Diagnostics Bone density (loss of 1-1.5 inches of height), X-rays, Quantitative computed tomography (QCT), Dual-energy X-ray Absorptiometry (DXA scan), Ultrasound
Estrogen Replacement Medications for Osteoporosis HRT (increased risk of cancer), Selective estrogen receptor modulators (SERMs): Raloxifene (Evista), Tamoxifen (Tamofen); Decreases risk of breast cancer; Estrogen related to bone loss, not reproduction; will still have hot flashes, irritability, etc.
Daily Calcium Needs 1000-1200 mg/day
Daily Vitamin D Needs 200-600 units/day
2 Kinds of Calcitonin for Osteoporosis Calcimar and Miacalcin (injection or nasal spray)
4 Kinds of Biphosphonates for Osteoporosis Alendronate (Fosamax) (once a week), Risedronate (Actonel), Ibandronate (Boniva) (once a month), and Reclast (once a year). Drug of choice. Preserves bone density.
Foods High in Calcium Green leafy veggies (Broccoli, collard greens, bok choy, spinach), Clams, oysters, sardines, salmon.
Paget's Disease Osteitis deformans, > calcium, 2nd common bone disease in US, Abnormal/excess bone resorption and formation, Chronic remodeling = Bones are larger and softer (Remind you of chalk, thick, but break easy), Affects the axial skeleton. Initially asymptomatic.
Musculoskeletal effects from Paget's Disease Pain aggravated with pressure, Deformity, Fractures, Muscle weakness.
Neurologic effects from Paget's Disease Scull abnormal thickening presses on the brain = Hearing loss, decreased level of consciousness, migraines, speech problems, ataxia (< coordination).
Cardiovascular Effects from Paget's Disease Increased vascularity (and skin temp) of the affected bones.
Metabolic Effects from Paget's Disease Hypercalcimia and Hypercalcimauria
Paget's Disease Diagnostics X-ray, CT, MRI, Alkaline Phosphatase. May be treated with surgery.
Medications for Paget's Disease Pain Relief (NSAID’s: Motrin or Indomethicin) and Suppress bone cell activity: Calcitonin and Biphosphonates.
Gout Hyperuricemia (> uric acid in blood). Urate crystals deposits in joints. Abrupt onset usually at night. Usually great toe joint initially. Increased risk for urate kidney stones.
Normal Uric Acid Levels 2.8 – 6.8 in women. 3.5 – 7.0 in men.
Gout Risk Factors Male, Diet rich in red meat/seafood, ETOH consumption, Soft drink with corn syrup, sweetener consumption, Dehydration, Aspirin.
5 things correlated to Gout Obesity, metabolic syndrome, hyperlipidemia, HTN, insulin resistance.
Primary Gout Error in purine metabolism=uric acid. Inherited as X-linked trait (momma gave it to me). Middle aged to older men. Post menopausal women.
Secondary Gout Hyperuricemia. Caused from another disease/diets. Some drugs: Lasix, PZA, cyclosporin, salicylates. All ages.
Stages of Gout Stage 1-Asymptomatic hyperuricemia: Uric acid levels 9-10 mg/dL. Stage 2-Acute Gouty Arthritis: Excruciating pain, inflamed joint, > WBC, Sed rate, triggered by the RF. Stage 3-Advanced gout: Chronic or tophaceus gout, Kidney disease.
Gout Collaborative Care Terminate acute attacks. Prevent recurrent attacks (Lifestyle changes, Refer back to RF). Reverse/prevent complications.
Acute Gout Drug Therapy Does not get rid of gout. Indomethicin (Indocin): Can be used for other pain relief. Colchicine (Colsalide): Only for gout (SE: abd cramping, n/v).
Gout Prevention Drug Therapy Allopurinal (Zyloprim): Prevents conversion of ziathem to uric acid, decreased serum uric acid. Probenecid (Benemid): Drink at least 3L/day, 2500 ml is normal/non gout intake.
Gout Nutritional Needs/Concerns Low purine diet, Increase fluids (>2L/day), Avoid: red meats, shellfish, excessive ETOH, yeast, beans, peas, spinach, aspargus, cauliflower, mushrooms, fad diets.
Gout Diagnostic Tests Serum uric acid, WBC, ESR or sed rate, 24-hour urine, Analysis of fluid aspirated from inflamed joint.
