Respiratory Flashcards
Stony Dull to percuss
Pleural Effusion
Right sided pleuritic chest pain
Most likely pneumonia
Alveolar bat wings Kerley B lines Cardiomegaly Dilated prominent upper lobe vessels Pleural effusion
Pulmonary oedema
Ground glass appearance on Xray
Pulmonary fibrosis and respiratory distress syndrome of the newborn
Xiehl Neelsen stain positive for acid fast bacilli
TB
Caseous necrosis
TB
Apical disease
Most likely (secondary) TB Apical lesion is called an Assmann focus
Military TB
Spread of organism into bloodstream. If organism spread via pulmonary artery, military dissemination in to the lung occurs. If organism spread via pulmonary vein, there is systemic dissemination to the liver, spleen and kidneys
Positive anti-glomerular basement membrane antibodies
Goodpasture’s syndrome
Chest infection with a parrot / pigeon as pet
Caused by chlamoydophila psittaci
Dry cough and diarrhoea after holiday abroad, some indication of water spread
Legionella pneumophila (test urine for antigens)
Tall, thin young man who indulges in marijuana
Probably pneumothorax (Marfan’s)
Bilateral hilar lymphadenopathy, erythema nodosum, granulomas, fatigue, uveitis and weight loss
Sarcoidosis
Bronchiole wider than neighbouring arteriole (on CT) (signet ring sign)
Bronchiectasis
D sign on X Ray
Empyema
Steeple sign on X ray
Laryngotracheobronchitis / croup
Child with barking cough
Croup
Pneumocystis pneumonia
HIV (treat with Co-tramoxazole)
Asthma + nasal polyps + salicylate sensitivity
Samter’s triad
Alcoholic (danger of aspiration pneumonia)
Klebstelle pneumoniae
Red jelly sputum
Klebsiella Pneumoniae
Mucoid sputum
Chlamydia psittaci
Rusty sputum
Pneumococcal pneumonia
Cannonball metastases (also weight loss and haematuria)
Classically from primary renal cell carcinoma
Morning headache
Hypercapnia or side effects of organic nitrates
ACTH secreting lung tumour
small cell carcinoma of the lung
PTH secreting lung tumour
squamous cell carcinoma of the lung
Small-cell carcinoma
Neuroendocrine, highly malignant and may be associated with ectopic endocrine syndromes
Increased serum ACE and Ca2+
Sarcoid
Eggshell calcification at hilar region
Silicosis
Heart failure cells seen in alveolar spaces
Macrophages that have absorbed haemosiderin - found in chronic pulmonary oedema and associated (sever) left ventricular heart failure
Also seen in long standing pulmonary hypertension
Hon focus
An area of infection and gaseous necrosis at the periphery of the lung, beneath the pleura - found in TB infection
Hon Focus rupture (rare) through the visceral pleura into the pleural cavity will produce tuberculous pleurisy
Acumen Focus
Apical lesion of secondary TB infection
Coin lesion found on chest radiographs
A rounded solitary lesion
The common lesions are: Primary bronchial or lung carcinoma
Metastatic tumour (esp. of kidney)
Bronchial haemartoma, Carcinoid tumour, Granulomatous inflammation, lung abscess
Horner’s syndrome
Can occur when there is a local spread of cancer to the intrathoracic nodes for a pan coast’s tumour. Signs include: ptosis (drooping of the eyelid) enophthalmos (sunken eye) miosis (small pupil) and lack of sweating on the ipsilateral (same side as invasion) side of the face. This is due to invasion, of the cervical sympathetic chain
Thumbprint sign on head Xray
epiglottitis
Inspiratory whoop/ barking cough
pertussis
Snow storm appearance of X ray
Baritosis, silicosis
Management of infective exacerbation of COPD
iSOAP Ipratropium Salbutamol Oxygen Amoxicillin Prednisolone
Non smoker + lung cancer
Peripheral - adenocarcinoma
Squamous + small cell lung cancers
Central
High d dimers
suspect (but not diagnose) Pulmonary Embolism (send for CTPA or V/Q scan)
Low d dimers
Exclude PE
Large PE
Thrombolysis.
Small PE
Low molecular weight heparin
