Human papilloma virus (HPV)-associated gynecological alteration in mothers of children with recurrent respiratory papillomatosis during long-term obs…
2007
Abstract Background : Human papilloma virus (HPV) is one of the most frequently observed sexually transmitted infections. The study' purpose was to investigate the relation between a mother's gynecological history and the local status of her child with recurrent respiratory papillomatosis (RRP). Methods : Forty-two patients enrolled in a prospective multicenter study between 1983 and 1990. The study included patients with juvenile-onset and adult-onset RRP. All patients underwent surgery and treatment with α-interferon. Thirty-eight patients were followed up until 31.01.2006. Twenty-five mothers of these patients participated in a parallel prospective study of genital HPV infection. In 1989…
2',5'-Oligoadenylate synthetase activity analysis and human papilloma virus typing as prognostic factors in patients with recurrent respiratory papil…

Objective: Determination of early prognostic factors in patients with recurrent respiratory papillomatosis is extremely important, so the major goal of our prospective, multicentre study was to evaluate (1) the feasibility of various factors to determine prognosis of the clinical course,as well as (2) the response to interferon-alpha therapy in recurrent respiratory papillomatosis. Methods: Forty-two patients with recurrent respiratory papillomatosis were treated with interferon-alpha (3 MU/m2 three times per week; mean therapy duration was 2.7 ± 1.8 years)in 1983–1994 and followed-up until 2003. Human papilloma virus (HPV) type, recurrent respiratory papillomatosis severity and 2′,5′-oligo…
Different patterns of cytokeratin expression in the normal epithelia of the upper respiratory tract
1985
The distribution and type of cytokeratins present in the normal human epithelia of the nasopharynx, oropharynx, tongue, palatine tonsil, epiglottis, vocal cord, and laryngeal ventricle were studied using immunohistochemical techniques and by gel electrophoresis of cytoskeletal proteins microdissected from frozen tissues. Noncornifying stratified epithelia covering the oropharynx, tongue, surface of the palatine tonsil, pharyngeal surface of the epiglottis, and vocal cord were all found to contain cytokeratins nos. 4, 5, 6, 13, 14, and 15, together with minor amounts of cytokeratin no. 19, i.e., a pattern similar to that previously reported for esophageal epithelium. The immunohistochemical …
Children and partners of patients with recurrent respiratory papillomatosis have no evidence of the disease during long-term observation.
2006
Summary Objective Recurrent respiratory papillomatosis (RRP) is the most common benign neoplasm affecting the larynx and upper respiratory tract. The aim of our study was to investigate whether children and partners of patients with RRP develop the same disease and to determine whether there is an impact of pregnancy on the course of RRP. Patients and methods Thirty-eight of 42 patients with RRP were accepted for a multicenter prospective study in Germany in 21.06.83–12.03.90. Mean follow-up duration was 15.3 ± 1.8 years. The data of partners of patients with RRP was collected during the period of observation and then updated via interviews in January 2006. Twenty-nine children and four gra…
