History
Physical exam
Testing

-ECG
-Chest X-ray
-lung function
Pulmonary causes of cough
Chronic (> 8 weeks)
Acute (< 8 weeks)
Lower airways
asthma
aspiration (1-3 yrs)
inhalation (fire,
accident)
Infection
Pleura and lung
diseases
Pneumonia
Pleurisy
Ptx
Pulmonary embolism
Lower airways and parenchymal
chronic bronchitis, COPD (chronic
obstructive pulmonary disease)
asthma, RADS (Reactive Airways Dysfunction
Syndrome)
eosinophilic pulmonary diseases
lung tumors
Infection
ILD/DPLD (syst+lung involv.)
(Interstitial lung disease/diffuse parenchymal lung d.)
aspiration
bronchiectasis
cystic fibrosis
bronchomalacia
rare causes (tracheobronchomegalia, amyloid
infiltr, tracheobronchopathia,
osteoplastica, polychondritis)
Extrapulmonary causes of cough
Acute (< 8 weeks)
Upper airways
- infectious (common cold)
- allergy
Cardiac diseases
with acute pulmomary
congestion
Chronic (> 8 weeks)
Upper airways
- chronic rhinitis, sinusitis,
pharyngitis, laryngitis
- vocal cord dysfunction
- OSA (obstructive sleep
apnoe syndrome)
GERD
Drug (ACE inhibitor:
angiotensin converting enzyme)
Cardiac diseases
- any incl. pulmonary
congestion
- endocarditis
Urgency in acute cough
1. Haemoptysis
7. History of malignant tumor
2. Severe chest pain
3. Dyspnoea
8. History of heavy smoking
4. High fever
(> 20 pack-year)
5. TB
- epidemiology
- contact with sick person
- homelessness
- illicit drug user
6. Immunsuppressed states
- CVID (common variable immunodeficiency)
- AIDS
- immunsuppressive therapy
Chronic cough without definite
chest X-ray or lung function
1. Upper airway disease
2. „cough variant asthma”
3. GERD (gastroesophageal reflux disease)
4. Taking ACE inhibitor
Chronic cough in diffuse parenchymatous
lung – or autoimmune disease
1. Due to lung involvement (Sjögren sy, Wegener,
systemic sclerosis, Churg-Strauss sy, IIP:idiopathic
interstitial pneumonia, sarcoidosis)
2. Due to treatment (methotrexate,
cyclophosphamide)
3. Due to infection in the
immunocompromised host
End-stage ILD, honeycomb lung
Frequent mistakes in the
diagnostic workup
1. Extensive diagnostics in patients taking ACE inhibitor
2. Trivialisation of cough in smokers without diagnostics
3. Extrapulmonary causes (E.N.T:ears, nose and throat,
cardiac, neurologic) are disregarded
4. Change of the established sequence of tests without
reason (e.g. HRCT before BHR: bronchial hyperresponsiveness
testing, PFT: pulmonary function test)
5. No bronchoscopy though cause not determined
6. Psycogenic cough diagnosed, tumor overlooked

Hemoptysis
• Hemoptysis is the expectoration (coughing
up) of blood or of blood-stained sputum from
the bronchi, larynx, trachea, or lungs.
• The origin of blood can be identified by
observing its color. Bright-red, foamy blood
comes from the respiratory tract, whereas
dark-red, coffee-coloured blood comes from
the gastrointestinal tract.
Etiology of hemoptysis I.
Neoplastic
Primary bronchial cc., pulmonary metastatic
disease, bronchial adenoma, Kaposi’s sarcoma
Infection
Bacterial pneumonia, tb, lung abscess,
aspergillus disease, parasitic disease, viral
infection (influenza, varicella)
Pulmonary
Bronchiectasis, bronchitis, cystic fibrosis,
cryptogenic organizing pneumonia
Vascular
PE, PH, AV malformations, bronchial artery
malformations, congenital vascular abnormalities,
aortic aneurysm, valvular heart diseases,
amniotic fluid embolism, hepatopulmonary sy,
pulmonary venous hypertension/congestive heart
failure
Haematological
Coagulopathies, lung transplant rejection,
thrombolysis, abnormal platelet function
Etiology of hemoptysis II.
Systemic
disease
Vasculitis, Goodpasture-sy, SLE, idiopathic
pulmonary haemosiderosis, diffuse alveolar
haemorrhage/capillaritis
Iatrogenic
Bronchoscopy, percutaneous lung biopsy,
radiotherapy, Swan-Ganz catheters, implantable
cardiac defibrillators
Drugs
Anticoagulants, aspirin, amiodarone, penicillamine,
solvents, crack cocaine
Miscellaneous

Dyspnoe
• Unpleasent or uncomfortable
breathing
• Difficulty in breathing, often
associated with lung or heart
disease and resulting in shortness
of breath.
Causes of dyspnea
Increased demand
Impaired performance
Physiological – exercise,
pregnancy, high altitude
1.Airflow limitation -asthma,
Pathological –
psychogenic, anaemia,
acidosis, increased
metabolism (fever, hyperthyreoidism)
COPD, large airway obstruction
2.Reduced lung volume
ptx,effusion, scoliosis
3.Impaired gas exchange
fibrosis, consolidation, edema,
collapse, COPD
4.Reduced compliancelung or thoracic cage
(Bechterew)
Time course of dyspnea
• Sudden onset: ptx, pulm.embol., asthmatic
attack, pulmonary edema, aspiration
• Days, weeks, months: pneumonia, tbc (bronchial spreading), anemia, tumorous occlusion,
pleurisies, CHF, obesity
• Years: asthma, COPD, ILD, pneumoconiosis,
autoimmune diseases with lung involvement
Types of dyspnea
• Orthopnea: Discomfort in breathing that is
relieved by sitting or standing in an erect position.
Inability to breathe except in an upright position
• Platypnea (orthodeoxia): accentuation of arterial
hypoxemia in the erect position.
• Trepopnea: dyspnea that is sensed while lying on
one side but not on the other. It results from disease
of one lung, one major bronchus, or chronic
congestive heart failure.
• Exercise-induced dyspnoe
Types of dyspnea
Diff.dg. - hyperpnea (increase in VE: minute
ventilation):abnormal increase in depth and rate of
respiration
- hyperventilation (increase in VA:
alveolar ventilation)Abnormally fast or deep
respiration resulting in the loss of CO2 from the blood,
causing a decrease in blood pressure and sometimes
fainting. Pulmonary ventilation rate greater than that
metabolically necessary for gas exchange, resulting
from an increased respiration rate, and/or increased
tidal volume.
It causes an excessive intake of O2 and elimination of
CO2 and may cause hyperoxygenenation. Hypocapnia
and respiratory alkalosis then occur, leading to
dizziness, faintness, numbness of the fingers / toes,
possibly syncope, and psychomotor impairment.

• Anamnesis
– Sudden sharp chest
pain on right side
– Dyspnea
• Physical exam
– Hyperresonant

– No breathing sounds

auscultation
Chest pain
• The heart, lung, esophagus, great vessels provide
afferent visceral input through the same thoracic
autonomic ganglia.
• Painful stimuli from thoracic organs can produce
discomfort described as pressure, burning, aching,
and sometimes sharp pain.
• Lung parenchyma and visceral pleura are
insensitive to pain
• Consider cardiac origin in case of risk factors or
exertional symptoms
• For anyone with chest pain minimal testing
includes pulse oxymetry, ECG, chest-Xray.
