Best evidence topic reports (BETs) summarise the evidence pertaining to particular clinical questions. They are not systematic reviews, but rather contain the best (highest level) evidence that can be practically obtained by busy practising clinicians. The search strategies used to find the best evidence are reported in detail in order to allow clinicians to update searches whenever necessary.
The BETs published below were first reported at the Critical Appraisal Journal Club at the Manchester Royal Infirmary.1 Each BET has been constructed in the four stages that have been described elsewhere.2 The BETs shown here together with those published previously and those currently under construction can be seen at http://www.bestbets.org.3 The four topics covered in this issue of the journal are:
-
Use of the McCoy laryngoscope in patients with suspected cervical spine fracture
-
White cell count and diagnosing appendicitis in pregnancy
-
Oral acyclovir in acute cutaneous herpes zoster
-
Urinary trypsinogen to rule out acute pancreatitis in patients with abdominal pain
