[Detection of human papillomavirus (H.P.V.) DNA in genital lesions using molecular hybridization]. / Détection du DNA des virus du papillomme humain (H.P.V.) dans les lésions génitales par hybridation moléculaire.

Detection of human papilloma virus in genitals lesions by molecular hybridization. Some H.P.V. types are sexually transmitted and infect genital organs. We have used molecular hybridization to examine the distribution of H.P.V. 6 or II and H.P.V. 16 in benign, premalignant and malignant genital lesions from 344 patients. The frequency of H.P.V. 16 positive cases increases as the cervical lesions progress to malignancy: 57/78 are positive (73%) in the carcinomas, 29/83 are positive (35%) in mild or moderate dysplasia. The majority of benign condylomata acuminata harbors DNA of other types, namely H.P.V. 6 and II.

[Future of the remaining rectum after treatment of familial polyposis (author's transl)]. / Devenir du rectum restant dans la polypose recto colique familliale.

In the treatment of familial polyposis the conservation of the rectum is essential to assure a convenient control and rhythm of defecation. Meanwhile the future of resting polyps deserves the attention of the surgeon. Certain authors are optimistic and claim that spontaneous regression of the polyps is possible. Our experience illustrates that the rectal mucosa tends to fabricate new crops of polyps. The prolonged post operative observation of more than 4 years of polyposis in one family has permitted us to follow the evolution of the rectal mucosa and to deduce that gravity of the lesion is quite variable. The polypotique character of the rectal mucosa must influence the choice of certain surgical technic specially that nine of them achieve entire satisfaction yet.
