Cyanide – anion gap acidosis – correction
The Cyanide page has been updated to correct the statement that cyanide causes a non-anion gap acidosis -it causes an anion gap acidosis as stated elsewhere on the page.
Corrections
CT in SAH – clarification
A statement on the Investigation of suspected subarachnoid haemorrhage page has been clarified. The statement ‘aneurysm may infrequently be seen if > 5 mm diameter’, in relation to CT head has been corrected to ‘aneurysm may occasionally seen if > 5 mm diameter’. Thanks to Raymund for picking this up.
Central cord syndrome – correction
The segment on central cord syndrome on the Spinal cord injury page has been corrected to reflect that weakness from central cord syndrome is greater distally than proximally in the limbs. Previously this was indicated to be the other way around due to the mistaken use of a ‘>’ sign instead of a ‘<‘ sign. … Read more
Rifampicin and NOACs – correction
A mistake in the Other anticoagulants page has been identified and corrected. Rifampicin is an inducer of NOAC metabolism, not an inhibitor of it.
ESR and CRP in SLE – correction
A correction has been made to the Systemic lupus erythematosus page. CRP does not correlate with disease activity, but ESR does (not the other way round as stated previously).
ACEM Fellowship exam practice quiz corrections
Two answers in the ACEM Fellowship exam practice quiz have just been discovered to be incorrect and have now been corrected. Unfortunately we can’t tell you which ones without giving the quiz contents away!
Well’s score table – correction
The table on the Pulmonary embolism page previously called Simplified Well’s score was actually just the original Well’s score. This has been corrected in the online version however not in the first 3 print runs of the print version.
Correction – specificity of lipase and amylase for pancreatitis
There is an error on the Pancreatitis page that will be corrected with the next file upload. Currently it states that higher amylase and lipase values are more sensitive for pancreatitis, when higher values are actually less sensitive but more specific.
Pacemaker demand / non demand mode – important correction!
There is a significant error in the wording on the Pacemakers page (page 110) regarding the set up of a transcutaneous pacemaker. This section should read: should be set to non demand mode when there is no organised rhythm set to demand mode if no there is an organised rhythm as this prevents pacing on Q wave … Read more
Correction – Smith’s fracture XRay
Image 29 on the Distal forearm injuries page (p 1649 of the print edition) demonstrating a lateral radiograph of fracture around the wrist is actually a Barton’s fracture, not a Smith’s fracture as previously described. Our Director of Eponymology has been sacked for this error.
Levonorgestrel vs Yuzpe regimen correction
The table summarising the difference in adverse effects of the Levonorgestrel and Yuzpe regimens on the Contraception page has been corrected. The Levonorgestrel and Yuzpe column headings were previously the wrong way around. Thanks to Aziz for picking this up. Also some additional information has been added to this section.
VT treatment algorithm
The VT management options algorithm on the Ventricular arrhythmias page has been corrected so the decision point ‘Na channel blocker toxicity or hyperkalaemia’ now has ‘yes’ and ‘no’ as options.
EDACS scores that might not need serial troponins
Print version 1 – Page 518 – Risk stratification of suspected ACS – Patients with an EDACS score of ≤ 5 may not need serial troponin testing, not ≥ 5 as stated.
New hyponatraemia diagnostic algorithm
A new Hyponatraemia diagnostic algorithm has replaced the old one on the Hyponatraemia page. This addresses the errors in the old algorithm regarding volume status in cerebral salt wasting syndrome and serum urate in SIAD.
JVP measurement
The Cardiovascular examination page has been updated with a correction. The base from which the JVP is measured is the manubriosternal angle, not the sternal notch (although the base of the notch in a patient at 45 degrees is probably not far off).
Hyponatraemia flowchart errors
The Assessment of hyponatraemia flowchart on the Hyponatraemia page has the following errors: SIAD also commonly has low serum urate (not normal as on the chart); cerebral salt wasting syndrome usually has some degree of hypovolaemia (not euvolaemia as on the chart). The flowchart will be updated to correct these errors as soon as possible.
Normal QRS amplitude correction
The Electrocardiography page has been corrected. The normal QRS amplitude should be ≥ 5mm in the limb leads and ≥ 10mm in the precordial leads not ≤ 5 and 10mm respectively as previously mentioned.
Fat embolism mortality rate correction
The Non thrombotic embolism page has been updated, but more importantly the error that stated that fat embolism is associated with a high mortality rate has been corrected. It is usually associated with a low mortality rate.
Hutchison fracture
Print version 1 – Distal forearm fractures – page 1649 – the ‘Hutchison’ fracture of the distal radius is erroneously described as the ‘Henderson’ fracture.
Ascitic fluid protein concentrations in SBP – correction
The table entitled Test characteristics of ascitic fluid analysis in the Spontaneous bacterial peritonitis page has been corrected to show that a protein concentration of > 1g/dL is 100% sensitive and 65% specific for SBP (not <1g/dL as previously shown).
