Study Notes

Ear Wax Impaction (Cerumen Impaction)

Earwax (cerumen) protects the external ear canal by trapping foreign particles.
The ear canal is self-cleaning, moving earwax to the external surface.
Symptoms include gradual hearing loss and a feeling of fullness in the ear.
High-risk groups include young children, older adults, hearing aid users, individuals with cognitive impairments, and residents of aged care facilities.
Treatment involves cerumenolytic agents such as olive oil, docusate, carbamide peroxide, and saline to soften and disperse wax.

Red Flags for Referral (Ear Conditions)

Pre-existing ear pathology
History of ear surgery
Perforated eardrum or grommets
Suspected infection (e.g., fever, malaise)
Trauma or pain
Foreign body in the ear
Sudden loss of hearing or treatment failure

Acute Otitis Externa (Swimmer's Ear)

Inflammation of the ear canal, often following water exposure (e.g., swimming).
Symptoms include Pain, itchiness, and hearing loss.
Prevention involves gently clearing water from the ear after swimming or bathing by lying on the affected side, using gravity or a towel to remove excess water, or creating a vacuum by pressing the palm against the ear and releasing.
Avoid cotton buds or electronic ear cleaner devices with cameras.
Over 30% of impacted ears clear naturally within 5 days.

Acute Otitis Media (Middle Ear Infection)

Viral infections can spread to the middle ear via the Eustachian tube, leading to fluid/pus accumulation and tympanic membrane inflammation.
Symptoms include ear pain (primary symptom), irritability, hearing loss, blocked sensation, and fever (sometimes with fluid discharge).
Treatment often involves symptomatic relief with paracetamol or ibuprofen.
Antibiotics aren't usually required unless an infant is <6 months old, or bilateral infection is present in a child <2 years of age, or the patient has severe symptoms or systemic illness.

Why Not Antibiotics?

Only 5 out of 100 children treated with antibiotics experience faster recovery at 2-3 days.
Initial antibiotic therapy often does not improve pain at 24 hours.
Antibiotics can cause harm (e.g., diarrhea, rash, hypersensitivity, bacterial resistance).

Chronic Otitis Media

Symptoms include persistent ear discharge, hearing loss, and typically painless unless actively infected.
Treatment involves topical antibiotics for discharge, and referral for surgical intervention (e.g., tympanoplasty) if a perforation persists.

Self-Care for Ear Health

Do not insert cotton buds or other objects into the ear canal.
Protect ears from excessive water exposure.
Use ear drops for maintenance if prone to wax buildup or swimmer's ear.
Avoid electronic ear cleaners.

Cough

Cough is a common presenting complaint in primary care, often associated with viral infections.
Types include non-productive (dry, tickly, hoarse, or hacking) and productive (chesty or phlegmy).

Cough Suppressants (Antitussives)

Centrally acting suppressants (e.g., dextromethorphan) have a limited role in self-limiting coughs, and are not recommended for people with respiratory conditions like COPD or asthma.
Dextromethorphan has the best side effect profile.

Expectorants

Examples include guaifenesin, senega, and ammonia.
Increase sputum production to aid in clearance.

Mucolytics

Reduce sputum viscosity for easier clearance.
Honey may offer symptom relief for children over 12 months of age.

Antihistamines

Not routinely recommended for acute cough.
Occasionally used in adults as a sleep aid.

Evidence-Based Considerations (OTC Cough Medicines)

A 2014 Cochrane review found no strong evidence for or against the use of OTC preparations for acute cough.

Harm Associated with medications

Harm associated with use in children (e.g., sedation, side effects).
Guaifenesin and Bromhexine may be recommended for productive cough in adults.
Sedating antihistamines may provide symptomatic relief but have side effects like drowsiness.

Summary of Approach to Cough

Determine if the cough is non-productive or productive.
Assess associated symptoms and red flags.
First-line treatment includes reassurance, hydration, and rest.
Consider a simple linctus or lozenges for throat irritation.
Use medications sparingly and based on symptom severity/type.
Limited role for mucolytics and expectorants in productive cough.
Referral to a specialist if necessary.

Key Takeaways (Cough)

Cough is mostly self-limiting and rarely requires pharmacological intervention.
Focus on identifying red flags and addressing patient concerns.
Avoid unnecessary antibiotics or medications for viral coughs, especially in children.

Travel health

Be vigilant for red flags and ensure timely referral for concerning symptoms.

Factors Influencing Individual Risk Profiles (Travel)

Itinerary (consider destination, country type, activities).
Timing (duration, seasonality).
Reason for travel (tourism, business, etc.).
Style of travel (independent vs package).
Special activities (extreme sports, wildlife interaction, etc.).

Red Flags for Referral (Travel)

Risk of altitude sickness (travel to high-altitude cities).
Malarial prophylaxis and complex itineraries.
Medical tourism or high-risk conditions requiring specialist care.
Extremes of climate (e.g., heat illness, winter hiking risks).
Activities involving extreme sports.
Exposure to animals (e.g., rabies).

Preventive Measures (Travel)

Vaccinations (routine, selected, country-specific).
Age and pregnancy status, underlying medical conditions, medications, travel activities, and available time before departure.
Insect bite prevention (clothing, repellents, nets).

Malaria Prophylaxis (Travel)

Assess risk based on the destination.
Provide advice on avoiding bites and refer for chemoprophylaxis if necessary.

Venous Thromboembolism (VTE) Prevention (Travel)

Risk factors include long-distance travel (>4 hours), flights over 8-10 hours, obesity, prior DVT, or immobility.
Recommendations include staying hydrated, mobilization of ankles and calves, periodic walking, avoidance of restrictive clothing, and consideration of compression stockings.

Food and Water Safety (Travel)

Avoid raw or undercooked foods.
Drink bottled or treated water.
Carry oral rehydration solutions for diarrheal illnesses.

Hygiene and First Aid (Travel)

Carry alcohol-based hand rub, soap, antiseptic cream, dressings, and a thermometer.

Managing Common Travel Conditions (e.g., Motion Sickness, Jet Lag, Infectious Diseases, Accidents and Injuries)

Motion sickness: Triggers: conflicting sensory input, anticholinergic/antihistamine medication as first-line prophylaxis, avoid heavy meals before travel, choose seats with minimal motion.
Jet lag: Adjust sleep schedule before departure to match destination time. Stay hydrated.,avoid excessive alcohol/caffeine.
Infectious diseases: Educate on hygiene and vaccination, provide prophylactic medications for specific conditions, emphasize seatbelt use, safe equipment for cycling, address minor wounds

Insurance and Medication Management (Travel)

Ensure medical coverage, especially for international travel.
Check policy details for emergency evacuation and treatment costs.
Calculate sufficient medication supply, including contingencies.
Pack medications securely and be aware of legal restrictions.
Adjust dosing schedules considering time zone changes.
Carry a letter from a medical professional.

Special Considerations (Travel)

High-altitude travel: Gradual ascent, acetazolamide prophylaxis if necessary.
Heat illness: Avoid overexertion, stay hydrated, wear appropriate clothing.
Animal exposure: (e.g., rabies): Wash bites immediately with soap and water and if appropriate seek medical care.

Threadworm (Enterobius vermicularis)

Threadworm is a common parasitic infection caused by Enterobius vermicularis.
Highly prevalent among children, but adults can also be affected.
Transmission: Spread through ingestion of eggs on contaminated surfaces (e.g., bedding, clothing, food) or through close contact with infected individuals.

Threadworm Life Cycle

Eggs hatch in the small intestine, releasing larvae.
Larvae mature in the large intestine.
Female worms migrate to the perianal area at night to lay eggs, causing itching.
Eggs spread through scratching, and can contaminate hands, under nails, and surfaces.

Threadworm Clinical Features

Key symptom: perianal itching (especially at night).
Other symptoms: restlessness, difficulty sleeping, abdominal pain (less common).
Visible worms in stool or around the anal area.

Threadworm Diagnosis

Tape test: Adhesive tape is applied to the perianal area in the morning, and examined for eggs under a microscope.
Visual identification: Worms may be visible around the anal area or in stool.

Threadworm Treatment

Pharmacological:
- First-line treatment: Mebendazole (single dose), repeat after 2 weeks if reinfection is suspected.
- Alternative: Albendazole.
Non-Pharmacological:
- Wash hands thoroughly;
- Keep fingernails short;
- Wash beding, clothing, and towels in hot water;
- Vacuum carpets and clean surfaces to remove eggs..
- Treating entire household for prevention of reinfection.

Threadworm Prevention

Encourage regular handwashing.
Avoid nail-biting and finger-sucking.
Educate on personal hygiene, particularly for children.

Oral Health: Dry Mouth (Xerostomia)

Causes of dry mouth include medications (e.g., antihistamines, antidepressants, diuretics), dehydration, medical conditions (e.g., Sjögren's syndrome, diabetes), and radiation therapy to the head/neck.
Clinical features include dry, sticky sensation, difficulty swallowing, increased risk of dental decay, oral infections (like thrush), and altered taste/burning sensation.
Management includes non-pharmacological (stay hydrated, suck on sugar-free lozenges or gum, use a humidifier) and pharmacological (artificial saliva substitutes, prescription salivary stimulants).

Oral Health: Mouth Ulcers (Aphthous Ulcers)

Causes include: minor trauma (e.g., biting cheek, dental appliances), stress, or hormonal changes.
Symptoms include painful round or oval sores with a white or yellow center and red border, typically found on inner cheeks, tongue, or lips.
Treatment includes symptomatic relief such as local anesthetics, antiseptic mouthwashes or gels, avoiding spicy, acidic, or hard foods, and for severe cases, topical corticosteroids. Other approaches include maintaining good oral hygiene and avoiding triggers.

Oral Health: Gingivitis

Causes include plaque buildup due to poor oral hygiene, risk factors such as smoking, hormonal changes, diabetes, certain medications.
Clinical features include red, swollen gums that may bleed during brushing/flossing, tenderness, and bad breath.
Management includes improving oral hygiene (brushing and flossing), professional dental cleaning, antibacterial mouthwash, antibiotics as required.

Oral Health: Halitosis (Bad Breath)

Causes include poor oral hygiene, dry mouth, gum disease, consuming odor-causing foods, and underlying conditions.
Symptoms include persistent unpleasant odor in the mouth or a coated tongue, or dry sensation.
Management includes: brushing teeth and tongue, hydration, use of sugar-free mints/gum, antibacterial mouthwash, and addressing underlying causes (e.g., sinus infections).

Practical Advice for Dry Mouth:

Stay hydrated, chew food thoroughly, chew sugar-free gum, avoid smoking, avoid acidic drinks/foods, limit caffeine and alcohol intake.
