1
Q
What are the specific symptoms of Klebsiella Infection?
A
Fever, productive cough, signs of sepsis.
2
Q
Why are these the symptoms of Klebsiella Infection?
A
Klebsiella pneumoniae causes severe lung infections, especially in people with conditions like diabetes or alcoholism. In Australia, if a patient has these symptoms along with sepsis, it’s a sign of a serious infection that needs quick treatment.
3
Q
What is the specific key diagnostic feature of Klebsiella Infection?
A
Positive culture showing Klebsiella.
4
Q
Why is this the key diagnostic feature of Klebsiella Infection?
A
In Australia, to confirm bacterial pneumonia like Klebsiella, doctors rely on lab cultures. Finding Klebsiella in these tests is crucial to choosing the right antibiotics.
5
Q
What are the differentials for Klebsiella Infection, and why are they considered?
A
Community-Acquired Pneumonia (CAP): Typically caused by Streptococcus pneumoniae. Aspiration Pneumonia: Often involves anaerobic bacteria due to aspiration of oropharyngeal contents.
6
Q
Why are these differentials considered for Klebsiella Infection?
A
In Australia, most pneumonia cases are caused by Streptococcus pneumoniae. However, if there’s a history of choking or swallowing issues, aspiration pneumonia is likely. Differentiating these conditions is important because they require different treatments.
7
Q
What is the specific initial investigation for Klebsiella Infection?
A
Blood and sputum cultures.
8
Q
Why is this the initial investigation for Klebsiella Infection?
A
Australian guidelines suggest doing blood and sputum cultures right away if severe pneumonia is suspected, especially in hospitals. This helps confirm which bacteria is causing the infection and guides the best treatment.
9
Q
What is the specific best investigation for Klebsiella Infection?
A
Culture and sensitivity testing.
10
Q
Why is this the best investigation for Klebsiella Infection?
A
In Australia, sensitivity testing is vital because it helps doctors choose the most effective antibiotics, especially with rising drug resistance. It ensures that the treatment will work against the specific Klebsiella strain causing the infection.
11
Q
What is the specific initial treatment for Klebsiella Infection?
A
Empirical antibiotics like ceftriaxone.
12
Q
Why is this the initial treatment for Klebsiella Infection?
A
Australian guidelines recommend starting with ceftriaxone for severe pneumonia, including suspected Klebsiella cases, because it works well against many bacteria until the exact cause is confirmed.
13
Q
What is the specific best treatment for Klebsiella Infection?
A
Switch to Klebsiella-sensitive antibiotics such as meropenem or ciprofloxacin.
14
Q
Why is this the best treatment for Klebsiella Infection?
A
Once lab results confirm Klebsiella, Australian guidelines suggest switching to more targeted antibiotics like meropenem or ciprofloxacin. This approach ensures the infection is effectively treated and helps prevent antibiotic resistance.
15
Q
What is the AMC exam focus for Klebsiella Infection?
A
Interpreting culture results and choosing appropriate antibiotics.
16
Q
Why is this the AMC exam focus for Klebsiella Infection?

17
Q
Example Question: A patient with pneumonia shows a sputum culture positive for Klebsiella. What is the most appropriate antibiotic to use?
A
Switch to meropenem or ciprofloxacin.
18
Q
Why is this the correct antibiotic for Klebsiella Infection?
A
In Australia, when Klebsiella is resistant to first-line antibiotics, meropenem or ciprofloxacin is recommended. These drugs are effective in clearing the infection.
19
Q
What are the specific symptoms of Severe Tics?
A
Repetitive, involuntary movements or vocalizations.
20
Q
Why are these the symptoms of Severe Tics?
