Resp Flashcards
Patient presents with epistaxis, rhinorrhoea. Resent blood tests show decline in renal function
1) Diagnosis
2) Other associated symptoms
3) ANCA status
4) Management .
1) GPA/Wegeners granulosis
2) Epitaxis, cough, haemoptysis, renal involvement = fatigue. Nerve and skin involvement
3) ANCE +
4) cyclophosphamide +/- rituximab
CXR/CT presentation of sarcoidosis
Hilar lymphadenopathy 50% of cases
Other presentations of sarcoidosis
fatigue weight loss cough chest pain fever
skin presentation of sarcoidosis
erythema nodosum
Patient presents with cough, low grade fever and chest pain, myalgia and fatigue
1) Most common CXR finding.
2) Diagnosis
3) skin finding
4) Associated eye condition
1) hilar lymphadenopathy
2) Sarcoidosis
3) erythema nodosum
4) Ant uveitis. Conjunctivitis
mx of sarcoidosis
6 months should resolve (WAW)
If not –> 30mg pred 6 weeks, then 15mg alt daily for 6 weeks
ANCA type in GPA
cANCA
pANCA is found in what granulomatous lung disease
Chur-Strauss
Eosinophilic, causes rhinitis and asthma
2 common causes of acute bronchitis
S. Pneumoniae
H influenzae
3 parts to COPD pathophysiology
Increased mucus cells and mucus production
Interstitial damage and reduced elasticity
squamous cell metaplasia
neutrophil infiltration
increased air space, more dead space
type 1 resP failure
Low Oxygen, normal CO2
type 2 resp failure
low oxygen, low co2
Cause of cor pulmonate
COPD Increased pulmonary pressure R sided heart strain R sided HF Peripheral oedema
Signs of cor pulmonale
Pulmonary hypertension and RV hypertrophy
Sternal heave
Loud second heart sound
First line management of COPD
SABA - salbutamol
or
SAMA - ipratropium
second line management of copd
combination of the above
third line x of copd
LABA - salmeterol
LAMA - tiotropium, umeclidinium
Add on treatments in copd
theophylline
prednisolone in exacerbations only
abx prophylaxis (macrocodes commonly used)
Investigations for asthma
PEFR - diurnal variation
Spirometry - 15% improvement on bronchodilator
first 3 steps of mx of asthma
1) SABA as and when
2) SABA + low dose ICS (beclo, budesonide). Can add LTRA (especially in children)
3) Add on LABA - salmeterol
steps 4-6 of asthma mx
4) High dose ICS + LABA + LTRA or theophylline
5) Regular oral corticosteroids
6) Hospital admission
Criteria for moderate asthma exacerbation
PEFR 50-70% predicted. Able to speak normally
Criteria for acute-severe asthma attack
30-50% predicted PEFR
RR>25 HR>110 O2 reaching 92%
Unable to talk in full sentences
Life threatening asthma attack criteria
<33% predicted PEFR
<92% O2
Altered consciousness
low BP
