Q

osteoporosis prevention

A
  1. Primary osteoporosis
  2. Low Vit. D level
  3. To prevent: consume adequate calcium (1,000 – 1,300 mg/day) and Vitamin D
  4. Engage in weight-bearing exercises
  5. Lifestyle modification: avoid smoking, alcohol, caffeine, carbonated beverages
  6. Secondary Osteoporosis- due to medications or diseases that affect bone metabolism.

Q

secondary osteoporosis

A

due to medications or diseases that affect bone metabolism

  • Use of corticosteroids, excessive alcohol intake
  • Specific disease: celiac disease; hypogonadism
  • Certain medications: anticonvulsants, thyroid replacements, anti-estrogen, androgen inhibitors, PPI.

Q

management of osteoporosis pharm

A

Calcium supplement with Vit. D tablet- take with Vit C/high vit. C drink

Osteoporosis Medications: (page 1207, Table 53.5) look in book for administration/special considerations

Q

dx for osteoporosis

A
  1. Xray- can reveal low bone density and fracture
  2. DXA (dual x-ray absorptiometry)
  3. QCT (quantitative computed tomography)
  4. Peripheral Quantitative Ultrasound

Q

DXA

A

Usually done in the hips or spine; used to screen early changes in bone density
health teaching: lie flat or stay x-ray table while the scan is going on, pt have to lie still/ follow instruction (ex: not good for people with dementia)

Q

gerontologic consideration

A
  • Women older than 80- prevalence is 50%
  • Men have higher mortality than women after sustaining hip fracture b/c - incidence of living alone in men is higher, men have less compliance
  • Older adults absorb dietary calcium less efficiently and excrete more readily via kidneys.

Q

osteoarthritis/ degenerative joint disease

A

OA is a noninflammatory degenerative disorder of the joints.

  • Usually on weight-bearing joints- hips/knees
  • Can also be seen in PIP (proximal interphalangeal) joints, DIP joints

14
Q

osteoarthritis patho

A

The articular cartilage breaks down- > progressive damage to the underlying bone- > formation of osteophytes (“bone spurs”)(protrude into the joint space)- > joint space is narrowed- > decreased joint movement.

The joint can progressively degenerate!

Q

osteoarthritis risk factors of disease and progression

A

16
Q

s/s of osteoarthritis

A

S/S: main: pain; morning stiffness; functional impairment (the onset is insidious and progressing over multiple years!), aggravated by movement and relieved by rest
- joints may be enlarged, decrease ROM

17
Q

tx for morning stiffness

A

warm bath

18
Q

management goal

A

Goal: decrease pain and stiffness; improve joint mobility

19
Q

how to manage osteoarthritis

A

Exercise- cardio, aerobic, lower extremity strength training
Weight loss
Complementary, alternative and integrative health therapies
pharmacologic therapy
surgical management: osteotomy, arthroplasty

20
Q

pharm management osteoarthritis

A
  • Initial: acetaminophen (2 tabs Q 6 hrs – extra strength 500 mg)
  • NSAIDs (alieve, ibuprofen, naproxen) - take w/ food
  • COX-2 (cyclooxygenase- 2) enzyme blockers (use cautiously!) Celecoxib (Celebrex) common SE is stroke or heart attack so max for 5 days
  • Opioid
  • Intra-articular corticosteroids (steroid injection)
  • Topical analgesics- like capcaisin
  • Topical diclofenac sodium gel (Voltaren)- FDA-approved
21
Q

osteomyelitis

A

Infection of the bone.

22
Q

osteomyelitis classification

A
  1. Hematogenous osteomyelitis- blood borne
  2. Contiguous- focus osteomyelitis- contamination from bone surgery, open fracture etc.
  3. Osteomyelitis with vascular insufficiency– commonly seen among patients with diabetes and PVDs.
23
Q

most common cause of osteomyelitis

A
Staphylococcus aureus (can be MRSA!)
Surgical ink markers used in surgery have been linked (cross-contamination)!
24
Q

s/s of osteomyelitis

A
  1. Systemic s/s
  2. Local: infected area: painful, swollen and tender
  3. Pain description: constant, pulsating that intensifies with movement.
  4. For chronic osteomyelitis: non-healing ulcer that overlies the infected wound - > intermittently drains pus
25
Q

dx osteomyelitis

A

x-ray - bone necrosis
radioisotope bone scan- determine area of infection
MRI
wound and blood culture- not a sensitive indicator

26
Q

management of osteomyelitis

A

drugs, surgical, supportive

27
Q

drugs osteomyelitis management

A

Note: bone is mostly avascular - > infection is harder to eradicate (no veins)
Antibiotic therapy is longer than for usual infections- 3-6 weeks (mostly IV)

28
Q

surgical management osteomyelitis

A

Intended for chronic and those that do not respond to antibiotics

Infected bone-> surgically exposed- > necrotic and purulent materials removed- > irrigated with sterile saline solution

29
Q

supportive measures for osteomyelitis

A

diet high in protein (healing), vitamins, correction of anemia, etc.

30
Q

prevention osteomyelitis

A
  • elective orthopedic surgery - must be postponed if pt has current infection (simple as UTI)
  • prompt tx of soft tissue infection (do not wait too long for tx)
  • surgical ink (one per pt)
  • tattoo sterilitiy
