25
what are the 2 tests to determine exposure to TB
-Tuberculin skin test (mantoux test, PPD) -interferon gamma release assay blood test
26
When a test to determine TB exposure are positive what is done
- chest xray - physical exam - preliminary diagnosis, sputum exam - definitive diagnosis: when seen in sputum, is is not confirmed but suspected, it must be grown in lab to confirm
27
what are oral manifestations of TB
mucosal leison, painful deep, irregular ulcer on dorsum of tongue, leisons can also occur on palate, lips, buccal mucosa, gingiva, glandular swellings
28
what things do we do to implement infection control measures in dental hygiene care with TB
- update med history - recognize signs, symptoms of tb - follow CDC guidelines - update written protocol
29
do you treat a pt with active tb
no
30
what do you do as far at tx in a patient with a history of tb
- use caution, discuss signs and symptoms - consult with physician, to confirm - tx is permitted when pt is free of clinically active disease
31
what is asthma
-chronic respiratory disease consisting of recurrent episodes of dyspnea, coughing, wheezing leading to bronchial inflammation and muscle constriction
32
what is extrinsic (allergic or atopic) asthma
- triggers outside of body - exaggerated response from inhalation of allergen - activation of airway epthelial mast cells
33
what is the most commmon type of asthma
extrinsic
34
what is intrinsic (non allergic) asthma
- triggers from within the body - triggers:emotional stress, GERD - usually seen in adults
35
What is drug or food induced (non allergenic, non atopic*
- aspirin - NSAIDS - beta blockers - food (nuts, shellfish, milk, strawberries) - tartrazine(yellow food dyes0 - metabisulfide preservative in food and drugs
36
what is exercise induced asthma
- vigorous physical activity | - thermal changes during inhalation of cold are may provoke irritation and airway hyperactivity
37
what is infection induced asthma
-lung infectoins may provoke symptoms
38
What is one type of IgE mediated hypersensitivity reaction
atopic asthma
39
what is IgE
- one of 5 types of antibodies | - primary defense against allergens, breaks them down and removes from body
40
people with asthma are beleived to hyperreact and produce more what
IgE antibodies, results are symptoms of asthma
41
What are the steps in an IgE mediated hypersensitivity reaction
1-inital exposure to allergen IgE produced and binds to mast cells 2-on subsequent exposures antigen binds to mast cells 3-mast cells release asthma mediators 4-asthma mediators cause bronchoconstricion, vasodilation, mucus producton
42
what is local anaphylaxis
- allergen binds to mast cell in nasal cavitiy resuling in nasal rhinitis - allergen binds to mast cell in bronchiole reusling in asthma
43
what is systemic anaphylaxisi
-allgergen binds to mast cells throughout the body resuling in anaphylaxis
44
what are signs and symptoms of an asthma attack
- chest tighness - ineffectiveness of brochodilator - wheezing, cough - dilated pupils - flushed - confusion - tachypnea - tachycardia
45
how to prepare for possible emergency care in a asthma attack
- signs and symptoms - stop tx - rule out obstruction - assist with inhaler - administer 02 - monitor vital signs
46
what are drugs to avoid that are asthma attack triggers or decrease respiratory function
aspirin, sulfite, NSAIDS | narcotics barbituates
47
what are the two main asthma medication types
- long term control | - quick releif meds
48
what are oral manifestations of beta 2 agonist inhalers?
- decrased salivary flow and biofilm pH | - causes and increase in GERD
49
What should you do before tx with patient who has asthma
-remined them to bring inhaler, assess risk level, have 02 available, stress free environment
50
what should you do during tx with a pt with asthma
- prevent triggering hypersensitive airway with isolation - use local without sulfites - fl2 tx
51
what is COPD
pulmonary disorders that obstruct airflow
52
what are the 2 most common diseases of COPD
chronic bronchitis and emphysema
53
what is the primary etiology of COPD
tobacco smoke with occupational and environmental pollutants as contributing factors
54
What is the etiology of chronic bronchitis
- excessive respiratory tract mucus production sufficient to cause a cough with expectoration for at least 3 months o the year for 2 or more years
55
in chronic bronchitis difficulty breathing is present on
inspiration and expiration
56
what are the signs and symptoms of chronic bronchitis
- chronic cough - copious sputum - chest radiograph abnormalities - sedentary , overweight, cyanotic, edematous
57
which disease is termed a blue bloater
chronic bronchitis
58
what disease is termed a pink puffer
emphysema
59
what is the etiology of emphysema
-distention of the air spaces distal to terminal bronchioles dues to destruction of alveolar walls
60
pts with ephysema have problems with breathing on
expiration
61
what are signs and symptoms of emphysema
- difficulty breathing on exertion - barrel chest - nonproductive cough - weight loss - chest x-ray abnormalities
62
what is the medical managment of COPD
no cure, decrease exacerbations (stop smoking, eliminate pollutants, adequate nutrition, drink water, exercise)
63
what are the 5 stages of COPD
at risk, mild, moderate, severe, very severe
64
what are oral manifestations of COPD
-similar to pts with asthma
65
What should we do before tx of a COPD patient
- precautions when cardiovascular problems present - assess severity of COPD - no N20 - tx preformed only on those with stable breathing - ID patients who may experience exacerbation of symptoms under stress - montiory b.p - appt length may need to be modified
66
In COPD what should you do during tx
- antimicrobial preprocedural r inse - avoid use of power driven scalers - local without epi
67
what should you do in education of COPD patients
- stop smoking - promote OH care - discuss link between COPD and perio - teach and promote oral self care exam - frequent appts
68
what is cystic fibrosis
-autosomal recessive gene disorder, progressive, ultimately fatal, involves pancreas liver, lung
69
what is affected in cystic fibrosis
gene disorder, affects salt and water in epithelial cells of the respiratory tract and exocrine glands and results in thickened secretions
70
what happens to the respiratory tract in cystic fibrosis
- airways are always filled with phlegm, similar to pus, leading to chronic sinusitis, opportunisitc lung infection
71
what happens to the pancreas and intestinal tract in cystic fibrosis
-thick mucus clogs pancreatic ducts, prevent release of enzymes, food isnt properly digested or absorbed
72
what is the medical management of cystic fybrosis patients
- antibiotics including inhalation solution - bronchodilators and anti-inflammatory agents - chest physiotherapy
73
what is dental hygiene care of cystic fibrosis patients
-oral manifestations: gingivitis associated with dry mouth, | facilitate breathing: adapt chair, no rubber dam
