resp Flashcards
4-month history of increasing breathlessness, fatigue and weight loss.
He is now retired but previously worked as a shipyard worker for 50 years
and he has a 40 pack-year smoking history.
cancer?
mesothelioma
Pneumothorax- what to avoid in lifestyle?
Pneumothorax -> life long ban on deep sea diving
Restrictive spirometry example?
FVC, FEV1, FEV1/FVC, TLCO?
pulmonary fibrosis, scoliosis, neuromuscular disorder, ARDS
FVC and FEV1 are reduced proportionately so the FEV1/FVC is normal/increased
FVC reduced <70% (significantly)
FEV1 reduced/normal
TLCO reduced (impaired gas exchange)
Obstructive spirometry example?
FVC, FEV1, FEV1/FVC, TLCO?
COPD, ASTHMA, CF, Bronchiatasis, alpha 1 antritrypsin
FEV1 AND FVC are reduced disproportionately FEV1/FVC reduced <70%
FVC normal or reduced
FEV1 reduced <80%
TLCO reduced (impaired gas exchange)
most common causes of bilateral hilar lymphadenopathy
sarcoidosis and tuberculosis.
All cases of pneumonia should have a …….. at 6 weeks after clinical resolution
All cases of pneumonia should have a repeat chest X-ray at 6 weeks after clinical resolution
admitted with acute severe asthma.
reatment is initiated with 100% oxygen, nebulised salbutamol and ipratropium bromide nebulisers and IV hydrocortisone.
no improvement. What is the next step in management?
IV MAG SULPHATE
A 23-year-old woman comes for review. Despite using beclometasone 200mcg bd she is regularly having to use her salbutamol inhaler. Her inhaler technique is good. next addition?
What is the main therapeutic benefit of inhaled corticosteroids in patients with COPD?
reduce frequency of exacerbations
diagnosed as having bilateral bronchiectasis following a high resolution CT scan. Which one of the following is most important in the long term control of his symptoms?
Symptom control in non-CF bronchiectasis - inspiratory muscle training + postural drainage
Most common organisms isolated from patients with bronchiectasis:
Haemophilus influenzae (most common)
Pseudomonas aeruginosa
Klebsiella spp.
Streptococcus pneumoniae
prescribed bupropion to help him quit smoking. What is the mechanism of action of bupropion?
Norepinephrine and dopamine reuptake inhibitor, and nicotinic antagonist
COPD- best type of oxygen device?
Bilevel Positive Airway Pressure (BIPAP)
first-line pharmacological treatment of COPD
SABA or SAMA (ipratropium)
LAMA(tiotropium)
target sats COPD
88% to 92%
CURB 65 score?
what score means treat at home?
Patients presenting to primary care who have pneumonia can usually be managed in the community with oral antibiotics if their CRB-65 score is 0
Confusion = 1
Respiratory rate ≥ 30 = 1
Blood pressure, SBP ≤ 90mmHg or DBP ≤ 60mmHg = 1
65 years and above = 1
(Urea is removed as this cannot be routinely tested in primary care).
distinguish pleural effusion
exudate vs transudate?
EXUDATE IF:
Effusion lactate dehydrogenase (LDH) level greater than 2/3 the upper limit of serum (blood) LDH
Pleural fluid LDH divided by serum LDH >0.6
Pleural fluid protein divided by serum protein >0.5
The commonest causes of an anterior mediastinum mass?
4 T’s:
teratoma
terrible lymphadenopathy
thymic mass
thyroid mass
anti-acetylcholine receptor antibodies in her blood.
dx?
Myasthenia gravis
The most common organism causing infective exacerbations of COPD is
Haemophilus influenzae
Pleural plaques indicate the patient has been exposed to asbestos 20-40 years prior.
This is seen on x ray findings, what todo next?
Pleural plaques are benign and do not undergo malignant change. They, therefore don’t require any follow-up.
Acute bronchitis management?
Management:
1. analgesia
2. good fluid intake
3. consider antibiotic therapy if patients:
are systemically very unwell
have pre-existing co-morbidities
have a CRP of 20-100mg/L (offer delayed prescription) or a CRP >100mg/L (offer antibiotics immediately)
NICE Clinical Knowledge Summaries/BNF currently recommend doxycycline first-line
doxycycline cannot be used in children or pregnant women
Acute bronchitis is a type of chest infection which is usually self-limiting in nature. It is a result of inflammation of the trachea and major bronchi and is therefore associated with oedematous large airways and the production of sputum.
Sarcoidosis presentation?
Painful shin rash- erythema nodosum,
cough
also affect the kidneys, giving hypercalcaemia- macrophages inside the granulomas cause an increased conversion of vitamin D to its active form (1,25-dihydroxycholecalciferol)
the lymphatic system, giving lymphadenopathy, and other organs/systems.
more common in people of Scandinavian or African descent.
Syndromes associated with sarcoidosis
Lofgren’s syndrome is an acute form of the disease characterised by bilateral hilar lymphadenopathy (BHL), erythema nodosum, fever and polyarthralgia. It usually carries an excellent prognosis
In Mikulicz syndrome* there is enlargement of the parotid and lacrimal glands due to sarcoidosis, tuberculosis or lymphoma
Heerfordt’s syndrome (uveoparotid fever) there is parotid enlargement, fever and uveitis secondary to sarcoidosis
