what investigation could you do if you suspect a patient has pneumonia
serum biochemistry blood count CXR throat swab urinary legionella Ag sputum microscopy and culture
what can you use to score the severity of pneumonia
the “CURB 65”
what does CURB 65 stand for
confusion
blood urea>7
respiratory rate>30
diastolic pressure65
if a patient scores a CURB of 0-1 what antibiotics should they be treated with
Amoxycillin or clarithromycin/ doxycycline
if a patient scores a CURB of 2 what antibiotics should they be treated with
Amoxycillin AND clarithromycin or levofloxacin
if a patient scores a CURB of 3-5 how should they be treated
Co-amoxiclav and clarithromycin or levofloxacin (if allergic to penicillin)
apart from antibiotics what other treatment can you give for pneumonia
oxygen
IV fluids
CPAP
intubation and ventilation
what does CPAP stand for
continuous positive airflow pressure
what are some common causes for Bronchiectasis
immotile cilia syndrome
cystic fibrosis
childhood infection-measels
what is hypogammaglobulinaemia
Hypogammaglobulinemia is an immune disorder characterized by a reduction in all types of gamma globulins, including antibodies that help fight infection.
what are the symptoms of Bronchiectasis
chronic cough
daily sputum-copious
sometimes - wheeze, dyspnoea, tiredness, flitting chest pains, haemoptysis
what are clinical signs that you may notice with bronchiectasis

What is Empyema

what is Haemolytic anaemia
Hemolytic anemia or haemolytic anemia is a form of anemia due to hemolysis, the abnormal breakdown of red blood cells
what are precipitins
