A
  1. underlying systemic disorder

2. radiation therapy to the head and neck

27
Q

What a likely underlying cause of hemiageusia? (loss of taste to only half the tongue)

A

ischemia/infarction of the brainstem

28

more than 200

29
Q

What % of patients with clinical depression complain of dysgeusia?

A

40%

30
Q

What are three local entities that clinicians should rule out as a cause of dysgeusia before considering systemic factors?

A
  1. abscess (perio or endo) 2. candidiasis 3. gingivitis/periodontitis
31
Q

For diagnosing dysgeusia: the clinician must be certain that the patient’s alteration is, in fact, a taste disorder rather than an olfactory one, because WHAT % of “flavor” information (e.g., taste, aroma, texture, temperature, and irritating properties) is derived from SMELL.

A

75%

32
Q

What is the term for dysgeusia that occurs without a stimulus?

A

phantom taste

33
Q

What fraction of dysgeusia patients experiecnce spontaneous resolution? How long does it take?

A

2/3 of patients, avg time 10 months

34

OA accounts for approximately WHAT % of patients evaluated for TMJ pain?

A

10%

37
Q

What is the change in pain throughout the day for OA?

A

gradual intensification, worse in the evening than the morning

38
Q

What are some treatment options for OA of the TMJ?

A
  1. analgesics/NSAIDS
  2. hot/cold packs
  3. occlusal splint
  4. lavage
  5. Glucosamine/chondroitin sulfate
  6. doxycycline
39
Q

What HLA locus has long been identified as the most significant genetic association for the development for RA?

A

HLA-DRB(beta)1

40
Q

What % of Americans are affected by RA? What % range of RA patients have TMJ involvment?

A

2-2.5%…50-75% (usually mild and clinically insignificant)

41
Q

What is the term for a reactive, macrophage-laden fibroblastic proliferation seen from the synovium to the joint surface in RA?

A

pannus

42
Q

RA: gender and age

A

affects women 3x more than men, but men diagnosed younger than women (25-35 years men, 35-45 years women)

43
Q

What is the classic look for the hands and the fingers for RA?

A

hands = ulnar deviation

fingers = swan neck deformities

44
Q

What are the pathognomonic findings in the skin near the affected joint in RA?

A

Rheumatoid nodules (20% of patients)

45
Q

What is the characteristic shape of joints affected by RA?

A

“anvil” shaped

46
Q

When the TMJ is affected in RA, what are the characteristics?

A

often bilateral, occurs late in the clinical course

47
Q

What can gross destruction of the condylar heads in RA do to a patient’s occlusion?

A

can develop class II, anterior open bite

48
Q

What is the specific serological marker for RA?

A

ACPAs (anti-citrullinated protein antibodies)

49
Q

80% of RA patients will have significant elevations in which serologic marker?

A

RF (rheumatoid factor)

50
Q

Which antibody is targeted by RF?

A

IgG

51
Q

Which serological marker is detected in 50% of patients with RA, but is not very specific?

A

ANAs (antinuclear antibodies)

52
Q

What blood value is elevated in 90% of RA patients during flare ups (active phase)?

A

ESR (not specific, but can monitor the clinical course of the disease)

53
Q

What is the histological buzzword for the findings of RA?

A

RICE BODIES - Typically, the membrane protrudes into the joint space as villi or fingerlike projections. These projections occasionally undergo necrosis, producing rice bodies—small whitish villi fragments composed of cellular debris admixed with fibrin and collagen

54
Q

What is the most frequently used disease modifying agent used for RA?

A

methotrexate (a folic acid inhibitor)

55
Q

TMD age and gender

A

primarily young and middle-aged women (but may affect any age and sex)

A

allodynia

57
Q

What are 3 inflammatory conditions frequently co-morbid with TMD?

A
  1. Lupus
  2. RA
