30
Cold infections are classified as
viral and cannot be treated with antibiotics
31
Cold Pathophysiology
- Viral Infection of upper respiratory tract - self-limiting with no cure, - transmission through aerosol and direct contact with virus •Most efficiently spread through direct inoculation of nasal mucosa or conjunctiva (mucous membrane that covers the front of the eye)
32
Cold Clinical Presentation
Sore throat, nasal symptoms, cough - low grade fever - generally lasts 7-14 days - Mucus: thin, clear, watery for 1-2 days, becomes thicker and may change to yellow or green and then back to thin/clear/watery at the end of illness
33
Cold Complications: What cold can lead to?
Sinusitis middle ear infection bronchitis pnuemonia
34
Cold vs. Allergy
Cold: Sore throat, nasal congestion, Sneezing, Rhinorrhea Allergy: Watery eyes, Itchy nose, eyes and throat, Nasal congestion. Red, irritated eyes
35
COVID course of illness
Exposure Once it hits peak thats when you have symptoms Then you recover Its becomes infectious before the peak and when symptoms occur and is no longer infectious when symptoms subside
36
Quarantine
Keeps someone who may have exposed to the virus away from other people if not vaccinated - Close contact: within 6 feet of someone who has COVID-19 for a total of 15 minutes or more
37
Isolation
Keeps someone is infected with the virus away from others (even in their home) - At least 10 days since symptoms first appeared - At least 24 hours with no fever without fever-reducing medication - tested positive, no symptoms: - 10 days have passed since the date you had your positive test
38
Exclusions to self care - cold
- Fever above 101.5 - chest pain - shortness of breath - worsening symptoms - underlying chronic lung issue ( COPD, CHF, Asthma) - AIDS - frail old patients - younger than 9 months - hypersensitivity to recommended OTC products
39
Nonpharmacologic Therapy for Cough/Cold
- Maintain fluid intake - rest - increased humidification - saline nasal sprays - warm soothing foods - nasal strips - aromatherapy - sleeping upright - nasal syringe for kids
40
Pharmacologic Therapy - cold Sore throat: Nasal congestion: Cough:
- treat symptoms Sore throat - local anesthetic, systemic analgesic Nasal Congestion - decongestant, first gen antihistamine Cough - antitussive, expectorant
41
Pharmacologic options- Sore throat
Local anesthetics - Benzocaine, dyclonine hydrochloride - Use every 2-4 hours - Lozenges, throat sprays, oral disintegrating stringents Systemic analgesic - Acetaminophen, Ibuprofen
42
Allergy- combo products?
Second generation antihistamine + decongestant common | - good option if congestion is an allergy symptom
43
Cough- combo product?
Combination antitussive + expectorant common - may be counterproductive but could use intermittently for a productive cough
44
Cold- Combo product
Single entity preferred over multi-product because various peak at different times
45
Aphthous Stomatitis (canker sores) Pathophysiology
- commonly unknown: local trauma may impact - smoking, biting inside of cheek - poor nutrition - immune-modulating diseases states - only affect labial or buccal mucosa - heal in 10-14 days
46
Aphthous Stomatitis (canker sores) Clinical Presentation
Epithelial ulceration - vary in number size and days present - May be difficult to distinguish from cold sores - can be painful - cannot be cured
47
Nonpharmacologic therapy - Aphthous Stomatitis (canker sores)
- Nutrition - avoid stress - ice - saline oral rinse -> 1-3 tsp salt to 4-8 ounces of warm water
48
Pharmacologic therapy - Aphthous Stomatitis (canker sores
- Topical oral protectants - topical oral anesthetics - oral wound cleansing agents such as Carbamide peroxide: 10-15% or Hydrogen Peroxide 1.5% - systemic analgesics
49
Canker sores Exclusions to self-care
Lesions associated with underlying pathology - Lesions present for 14 days or more - Frequently occurring lesions - Symptoms of systemic illness - Failure of appropriate self-care treatment
50
Canker sores Follow up
Seek medical care if: Symptoms do not improve 7 days of treatment Lesions do not heal in 14 days Symptoms worsen
51
Herpes Simplex Labialis (HSL)
Cold sores - up to 67% or people infected - Traditionally: Herpes Simplex Virus (HSV-1)
52
HSL Pathophysiology
``` Transmitted via direct contact (fluid) - Viable on surfaces for several hours Often through kissing or sharing drinks - Enters host through break in skin or membrane -Latent phase in trigeminal ganglia - Reactivated upon exposure to a trigger • Fever, injury, stress, immunosupression, menstruation - Infected for life ```
53
HSL Clinical Presentation
- Commonly occurs on lips or areas bordering lips - small red papules of fluid (1-3mm in diameter) Symptoms may be painful cosmetically objectionable, malaise, fever, pus
54
Prodrome
Medical term for early signs or symptoms of an illness or health problem that appear before the major signs or symptoms start
55
HSL Prodrome
Burning, itching, tingling in area prior to lesion appearance
56
HSL Exclusions to Self-Care
Lesions present 14 days or more - Increased frequency of outbreaks - Compromised immunity - Symptoms of infection (fever, swollen glands) - No previous diagnosis of cold sore
57
HSL Goals of treatment
- Relieve pain and irritation - Prevent secondary infection - Prevent spread of lesions
58
HSL Treatment approach
Differentiate recurrent aphthous stomatitis - OTC skin protectant + Topical docasanol 10% + topical/systemic anesthetic(Lidocaine) - Protect lesion from infection
59
HSL Non-pharmacologic Recommendations
Clean area with gentle soap and water - Keep lesion moist to prevent cracking - Avoid triggers: Local trauma, sun exposure
60
HSL Treatment- Info about treatment
Docosanol 10% (Abreva), systemic antivirals - Prevents viral replication - Only FDA approved product - Reduces duration and severity of the symptoms •20% reduction in median times to cessation of symptoms compared to placebo
61
Patient education-HSL
Lesions are contagious Condition is self-limiting There are Treatment options
62
Docosanol 10%
Abreva - Apply at first sign of an outbreak • 5 times/day until lesion has healed up to 10 days •Improved outcomes with earlier application -Prevents viral applications
63
These relieve pain but do not reduce symptoms duration
- Topical skin protectants - External application of topical analgesics - Systemic analgesics
64
Systemic Antivirals:
Superior to topical therapy | Prescription only
