Lack of human papillomavirus in pterygium of Chinese patients from Taiwan

Abstract

Optimal conditions required for the creation of an iatrogenic chorioretinal venous anastomosis in the dog using argon green laser photocoagulation.

Lack of papillomavirus (HPV) in pterygia of a Brazilian sample

“…Comparing the HPV positivity in the patients with pterygium, the incidence of pterygia of Italian cases was 100% (17/17) but 21% (5/24) among Ecuadorian patients (11) . And in China the HPV in pterygium samples was 100% negative, the same seen in the Botucatu region (12) . Thus it seems that the differences in the frequency of HPV distribution in the pterygium patients could be related to geographic aspects.…”

“…Because some authors postulate a potential relationship between pterygia and neoplastic lesion, some studies about the positivity of oncogenic viruses, such as HPV and HSV in the lesion were performed (2)(3)(4)(5)(6) . However, HPV occurrence in pterygium lesion is still controversial and sometimes a positive correlation between pterygia and HPV infection has been reported (3,(7)(8)(9)(10)(11) , while other present negative results (4,12) . The present study was done with the purpose to evaluate whether HPV is involved in pterygium pathogenesis in our region.…”

Association of human papilloma virus with pterygia and ocular-surface squamous neoplasia

“…6 After entering key words 'Pterygia' and 'HPV' into PubMed and further refining the search to include only original articles written in English that assessed four or more biological samples from patients with pterygia, 18 articles were selected. Eleven investigations detected HPVs, [27][28][29][30][31][32][33][34][35][36][37] whereas other studies were unable to detect the virus [38][39][40][41][42][43][44] ( Figure 1a and Table 1). From these 18 studies, the average prevalence for HPV was 18.6% (range 0-100%), corresponding to 136/731 positive specimens ( Figure 1a).…”

Presence of Human Papillomavirus in Pterygium in Taiwan

“…[11][12][13][14][15] Human papillomavirus (HPV), a potentially tumorigenic virus, has been implicated in the pathogenesis of pterygium. [11][12][13][14][15][16] The involvement of HPV in pterygia ranged from 0% to 100% in different geographical regions.…”

[11][12][13][14][15][16] The involvement of HPV in pterygia ranged from 0% to 100% in different geographical regions. [11][12][13][14][15][16][17][18] Previously, Chen et al 14 were unable to detect HPV by using polymerase chain reaction (PCR) in 65 pterygia in patients from Taiwan.…”
