In addition, conjunctival resection can be performed to temporarily remove local inflammatory mediators, followed by the use of immunosuppressants. Prognosis
Currently, there are limited studies regarding the prognosis of PUK. However, one study has pointed out possible complications surrounding PUK include moderate to severe vision loss, corneal perforation and increased risk of recurrence. Epidemiology
PUK is a rare condition with an estimated incidence of 3 per million annually. Studies have reported that most patients with PUK are older than 60 years of age (32%). Among them, men have a higher occurrence rate in men (60%). Most patients live in rural areas (66%) and are in the lower socioeconomic groups. The age of those with PUK ranges from 5 to 89 years, with a mean age of 45.5 years.The mortality rate after PUK diagnosis in an investigation of 34 patients with and without immunosuppressive medication is 53% and 5%, respectively. Another single-centre study involving 46 patients with RA reported a mortality rate of 15%. Reports have also shown a possibility of PUK occurrence after any ocular surgery. In a retrospective study of 771 eyes, 1.4% of participants reported developing late-onset PUK at an average of 3–6 months after surgery. == References ==

Y. pestis is the causative agent of plague. The disease caused by Y. enterocolitica is called yersiniosis. Yersinia may be associated with Crohns disease, an inflammatory autoimmune condition of the gut. Iranian sufferers of Crohns disease were more likely to have had earlier exposure to refrigerators at home, consistent with its unusual ability to thrive at low temperatures. Yersinia is implicated as one of the causes of reactive arthritis worldwide.Also, the genus is associated with pseudoappendicitis, which is an incorrect diagnosis of appendicitis due to a similar presentation. History
Y. pestis, the first known species, was identified in 1894 by A.E.J. Yersin, a Swiss bacteriologist, and Kitasato Shibasaburō, a Japanese bacteriologist. It was formerly described as Pasteurella pestis (known trivially as the plague-bacillus) by Lehmann and Neumann in 1896. In 1944, van Loghem reclassified the species P. pestis and P. rondentium into a new genus, Yersinia. Following the introduction of the bacteriological code, it was accepted as valid in 1980.
