• I’ve mentioned it before
• Essentially found shocked septic kids in Africa did worse with fluid boluses over maintenance fluid
• Comment from the floor was “yeah but they’ll all have malaria and the fluid will make their cerebral oedema worse”
• Fair enough

• The non-anaemic and non-malaria patients were analysed
• Found to have the same poor outcomes with fluid boluses over maintenance fluids as the anaemia and malaria kids
• Regardless of whether albumin or crystalloids given

• Smith modified Sgarbossa rule:
• At least one lead with concordant STE (Sgarbossa criterion 1) or
• At least one lead of V1-V3 with concordant ST depression (Sgarbossa criterion 2) or
• Proportionally excessively discordant ST elevation in V1-V4, as defined by an ST/S ratio of equal to or more than 0.20 and at least 2 mm of STE. (this replaces Sgarbossa criterion 3 which uses an absolute of 5mm)

• Drug hypersensitivity syndrome is the same as DRESS
• SJS/TEN
• Acute generalised exanthematous pustulosis (AGEP)
• drug induced erythroderma
• Severe, unexpected reaction to a medicine(s)
• high fever, a morbilliform skin rash
• inflammation of one or more internal organs including the liver, kidneys, lungs and/or heart
• It generally starts two to eight weeks after taking the responsible medicine.

• >30 min of CPR
• Evidence of unresponsive hypoperfusion and microcirculatory failure:
• pH <7.2 and Lactate >7
• Age >85
• End-Stage Renal Disease (ESRD
• Non-Cardiac Causes: Cardiac arrest due to drugs, drowning, acute stroke, terminal cancer and trauma, just to name a few non-cardiac causes, are likely to result in poor outcomes post-resuscitation.

C E N T O R
• History of fever
• Tonsillar exudates
• Tender anterior cervical adenopathy
• Absence of cough
• The Modified Centor Criteria add the patient's age to the criteria
• Age <15 add 1 point
• Age >44 subtract 1 point
• -1, 0 or 1 points - No antibiotic or throat culture necessary (Risk of strep. infection <10%)
• 2 or 3 points - Should receive a throat culture and treat with an antibiotic if culture is positive (Risk of strep. infection 32% if 3 criteria, 15% if 2)
• 4 or 5 points - Treat empirically with an antibiotic (Risk of strep. infection 56%)
• The presence of all four variables indicates a 40 - 60% positive predictive value for a culture of the throat to test positive for Group A Streptococcus bacteria. The absence of all four variables indicates a negative predictive value of greater than 80%
