facts needing confirmation 

 There are so many dubious statements in this article it's got me really questioning much of it. I'm not an expert but I'm pretty sure that at least half of the following is wrong or misleading: 

  
 Anal fissure .... is usually shallow (less than a quarter of inch or 0.64 cm deep). (ES: i'd have thought less than this but not sure) 

 Causes: Various causes of this fissure include:... 
 ... *severe and chronic diarrhea (ES: really??) 
 *Crohn's disease (ES: chron's causes fistulas which are quite diferent from fissurs... so dunno about fissure) 
 *spastic tight sphincter muscles 

 Anal fissure is common in women after childbirth and in infants.... (ES: i don't think so. after childbirth women may suffer lacerations that may involve the anus but these aren fissures!) 

 Prevention: In infants under one year old, frequent diaper change can prevent anal fissure.  For adults, the following can help prevent fissure: (ES: that may prevent nappy rash!!! a very different thing) 
 ... *Treating diarrhea promptly ... (ES: this is very dubious) 
 *Using a moist wipe instead of perfumed and harsh toilet paper. (ES: this may help but not really sure) 
 *Keeping the anus dry and hygienic. (ES: this may help but not really sure) 

 Treatment: Anal fissures in infants usually self-heal without anything more than frequently changing diapers. (ES: this whole anal fissure in baby thing seems very odd... and again the management would be treating the constibpation and analgesia... not diaper changes) 

 Deep fissures, ... surgery ... (ES: I think this whole section sounds out of date and needs verification)
