Pneumonia
Lights criteria (High protein and LDH = exudate), determines presence of exudate with protein and LDH levels
- Pleural fluid protein to serum protein ratio >0.5
- Pleural fluid LDH to serum LDH ratio >0.6
- Pleural fluid level >2/3 of upper value for serum LDH
- Additional criteria – Confirm exudate if results equivocal
- Serum albumin – pleural fluid albumin <1.2g/dL
Hip Dislocation
- Early identification and reduction is key to prevent complications
- Always perform a full trauma and neuro exam, particularly of ipsilateral joints as concomitant injuries are common with traumatic dislocations
- Don’t be reassured by negative post-reduction XRs as small fractures can occur. You should always consider CT
