Haemoptysis Flashcards

1
Q

What can haemoptysis be confused with? (3)

A

• Haematemesis: brownish-red blood that is vomited from the gastrointestinal (GI) tract.
• Epistaxis (nosebleed): particularly posterior nosebleeds.
• Bleeding gums: combined with a cough, this may be confused with true
haemoptysis.

Q

How can you check a patient presenting with haemoptysis is really haemoptysis? (6)

A

Ask them where they think the blood is coming from (e.g. initially from nose), colour (darker = partially digested), clots and history of N&V, gastric disease and alcoholism

Q

What does frank blood haemoptysis suggest? (6)

Q

What does blood-streaked sputum haemoptysis suggest? (2)

any infection of the lungs can cause this; however, in the context of chronic production of large volumes of sputum this
would suggest bronchiectasis.

Q

What can the speed of onset and progression of haemoptysis suggest? (Sudden and gradual 2)

Sudden onset is consistent with pulmonary embolism (PE) or erosion of a cancer into a large pulmonary blood vessel. Gradual onset argues for a progressive condition such as lung cancer or bronchiectasis.

51
Q

In someone with TB, in addition to reviewing need for resuscitation, what are the other 6 steps you need to take)

A

1) Ensurethatmicrobiologyknowtolookforacid-fastbacilli(i.e.usingaZiehl–Nielson or silver stain). Bear in mind that M. tuberculosis is a very slow-growing bacterium and it can therefore take many weeks before a positive result is obtained on culture.
2) TB is a notifiable disease so you must notify the authorities for contact tracing. They may vaccinate contacts with Bacille Calmette–Guérin (BCG) and, rarely, provide prophylactic therapy.
3) Place the patient in isolation to prevent further spread.
4) Test her for HIV, as although she most likely acquired TB during her childhood she may have acquired it more recently secondary to HIV infection which has implications for prognosis and management.
5) Look for signs of spread to other organs. Check particularly for meningeal irritation, bone or joint pain particularly in weight-bearing joints (e.g. Pott’s fracture in the spinal column), dysuria or pelvic pain (genitourinary infection), or abdominal pain.
6) If the diagnosis is confirmed, refer the patient to the TB service, which offers specialized care for such patients.

52
Q

Mx for TB?

A

rifampicin and isoniazid for the first 4 months, pyrazinamide and ethambutol for the first 2 months.

53
Q

What is primary ciliary dyskinesia?

A

an autosomal recessive disorder that affects the protein machinery used by epithelial cells to rhythmically beat their cilia and by spermatozoa to rhythmically beat their tails.

54
Q

Consequences of primary ciliary dyskinesia? (5)

A
  • Bronchiectasis, due to an inability to clear mucus from the lungs.
  • Rhinitis and sinusitis, due to an inability to clear mucus from the nasal sinuses.
  • Otitis media (both secretory and acutely infective) due to an inability to clear mucus from the middle ear, down the Eustachian tube.
  • Male infertility, due to sperm immotility. Females are usually fertile because passage of the oocyte along the Fallopian tubes is more dependent on peri- stalsis of the Fallopian tubes than on the movement of the ciliae that line these tubes.
  • Situs inversus. The rhythmical beating of cilia is thought to play an impor- tant part in setting up the usual pattern of body asymmetry during embryo- genesis. Many patients with PCD have their organs on the ‘other side’ (e.g. dextrocardia).
55
Q

What is Kartagener’s syndrome

A

Bronchiectasis, sinusitis, and situs inversus with PCD

56
Q

What indicates pulmonary renal syndrome

A

The combination of haemoptysis and glomerulonephritis (the presence of red cell casts (clumps of red cells that have squeezed through the glomeruli)) should alert you to the possibility of a pulmonary–renal syndrome.

57
Q

What does haemoptysis with glomerulonephritis (the presence of red cell casts (clumps of red cells that have squeezed through the glomeruli)) indicate?

A

Pulmonary-renal syndrome

58
Q

What is the difference between transudate and exudate? What causes it (7 and 3)?

A

The protein content
• A transudate is defined as having <25 g/L of protein. Transudates are low in protein because they are the result of fluid alone squeezing into the pleural space, either due to increased hydrostatic pressure in the lung vasculature (heart failure, fluid overload, constrictive pericarditis) or due to reduction in the oncotic pressure which usually keeps fluid in the vasculature (reduced serum protein due to liver failure, malabsorption/malnutrition, nephrotic syndrome).
• An exudate is defined as having >35 g/L of protein. Exudates are rich in protein because they are the result of cells in the pleural space: either pathogens (infection), inflammatory cells, or malignant cells.

59
Q 
Causes of clubbing:
Cardiovascular 5

GI 6
Other 2
A

− Atrial myxoma
− Axillary artery aneurysm
− Brachial arteriovenous fistula
• Respiratory
− Pulmonary fibrosis
− Suppurative lung diseases: abscess, empyema, cystic fibrosis, bronchiectasis
− Bronchial carcinoma, mesothelioma

• Gastrointestinal
− Inflammatory bowel disease
− Cirrhosis
− Malabsorption, e.g. coeliac disease
− Gastric lymphoma
− Liver abscess
− Liver or bowel cancer
• Other
− Congenital clubbing
− Thyroid acropachy
60
Q

Lung neoplasm classifications?

A

As for all neoplasms, lung neoplasms can at first be divided into benign and malignant. Malignant tumours in turn can be classified as primary or secondary. Broadly speaking, the primary malignant lung cancers are then classified in two groups based on histology:
1) Non-small cell lung cancer (NSCLC, 80%)
− Subdivided into adenocarcinoma (30–40%), squamous (20–30%), large cell carcinoma (10%), and
others (5%)

2) Small cell lung cancer (SCLC, 20%)

Haemoptysis is more common in squamous cell carcinoma, which usually affects lung tissue closer to the hilar region and thus the blood has relatively little distance to travel before being coughed up.

61
Q

Which cancers commonly metastasise to the lungs? (5)

A

Colorectal
• Breast
• Renal
• Female genital tract: cervix, ovary

62
Q

What ectopic secretion are associated with lung cancers?

A

ADH - leading to hyponatraemia
ACTH - leading to Cushing’s syndrome
PTHrP - leading to hypercalcaemia

63
Q

Common extra-pulmonary sites of manifestation of TB? (3) What does each cause (3, 2, 1)

A
  • Bone: osteomyelitis, septic arthritis, Pott’s disease (in the spine)
  • Neurological: meningitis, intracranial granulomas
  • Renal: granuloma
64
Q

Differentials for a solitary coin lesson on CXR? (7)

A 
Parenchymal tumour: benign, primary lung cancer, secondary lung cancer
• Lymph node: lymphoma
• Granuloma: TB, sarcoidosis
• Abscess
• Hamartoma
• Foreign object
