Disease + Pathology + Pharmacology Flashcards
Signs, symptoms, tests & treatment
What is coryza + 3 causes (+ most common) + 5 complications + treatment?
- Viral URTI
- Rhinovirus (most common), adenovirus and RSV
- Acute sinusitis, pharyngitis, bronchitis, laryngitis and otitis media
- None (can take NSAIDs)
What is sinusitis + treatment for bacterial and viral sinusitis + chronic sinusitis is a sign of?
Infection of the facial sinuses + amoxicillin for bacterial and none for viral + CF
What is laryngitis + what it causes + treatment for bacterial and viral?
Oedema of the vocal cords + hoarseness + amoxicillin for bacterial and none for viral
What is pharyngitis + main cause + what is it commonly assoiciated with?
Sore throat + adenovirus + common cold/ coryza
What is acute bronchitis + key symptom + causes in healthy vs lung disease patients + treatment?
Infection of the bronchi + productive cough + viral (healthy) and bacterial (lung disease) + NO ANTIOBIOTICS unless has existing lung condition
Incubation period for coryza?
1 - 5 days
Incubation period for influenza?
1-3 days
4 key symptoms of influenza + diagnosis + complication + treatment?
Fever, malaise, myalgia and cough + naso swab and PCR + secondary pneumonia via strep, staph or haemophilus + < 48 hrs = oseltamivir or zanamivir OR > 48 hrs = fluids, NSAIDs, bed rest
Which influenza is responsible for pandemics + why?
Influenza A + rapid antigenic shift
Who is the influenza vaccine contraindicated for?
People with an egg allergy
What is epiglottitis + key pathogen + x-ray sign + complication + treatment?
Severe upper airway obstruction + h. influenzae thumbprint x-ray sign + septicaemia + intubation, IV abx, adrenaline and oxygen
What is rhinitis + time scale for acute vs chronic?
Inflammation of the nasal mucosa + < 6 weeks (acute) and > 6 weeks (chronic)
4 main symptoms of rhinits + 2 types of allergic + causes?
Rhinorrhoea, sneezing, itching and congestion + seasonal (SAR) = pollen/ hayfever + perennial (PAR) = dust mite excretion
Causes of non-allergic rhinits + vasomotor rhinitis ?
Bacterial or viral infection + smells, temperature, emotion
Key feature commonly seen with all type of rhinitis + what they are + respond well to?
Nasal polyps + pale outgrowths of the sinus mucosa that contain mast cells and eosinophils + oral steroids
Summary of allergic rhinitis immunology?
IgE binds to mast cells and causes degranulation which releases histamine
Most effective rhinitis treatment + drug examples + additional 4 drugs that can be used?
Steroids (beclomethasone) + H1 antihistamine (loratadine, cetirizine) + LTRAs, oxymetazoline, ipratropium and cromones
Which types of H1 antagonists are preferred + 2 reasons why?
2nd generation as they do not cross the BBB or cause sedation
What is oxymetazoline + action + what common disease is it used for?
alpha 1 agonist + vasoconstriction + rhinorrhoea in rhinitis
Who does bronchiolitis present + 2 key symptoms + diagnosis + 2 organisms + treatment?
Child < 18 months + poor feeding and cough/wheeze + naso swab and PCR + RSV and metapneumovirus + palivuzimab and oxygen
What is whooping cough + key pathogen + classic presentiation + duration of being infective + treatment?
Trachea-bronchitis + bordatella pertussis + initial cold-like symptoms then sudden whoop coughing fits + 2 weeks + macrolide
What type of organism is bordatella pertussis and h. influenzae?
Gram -ve coccobacilli
What is croup + key pathogen + key symptom + x-ray sign + treatment?
Laryngotracheobronchitis + human parainfluenza virus (HPIV) + barking cough + steeple sign + IV adrenaline, steroid and oxygen
Main immunological cause of chronic vs acute infection?
Hypogammaglobulinemia (chronic) vs IgA deficiency (acute)
