Purpose

The purpose of the present study was to identify risk factors for more severe juvenile Recurrent Respiratory Papillomatosis (RRP) through prospective evaluation of a pediatric population in Thailand by the employing a protocol that includes staging of disease severity using above mentioned staging system at the time of each endoscopic debridement, as well as human papilloma virus (HPV) genotyping.

Condition	Intervention
Recurrent Laryngeal Papillomatosis Human Papilloma Virus	Procedure: biopsy

Study Type:	Observational
Study Design:	Observational Model: Case-Only Time Perspective: Prospective

Intervention Details:

excisional biopsy

Detailed Description:

Recurrent respiratory papillomatosis is caused by human papilloma virus and is the most common benign laryngeal neoplasm in children. Although RRP is rarely fatal, the disease requires prolonged, extensive medical and surgical treatment, and causes physical and emotional suffering in affected children and their families. Although recurrent respiratory papillomatosis is a relatively unusual problem, it accounts for significant health are expenditures.The goal of management of RRP is control of the disease, preservation of the voice and prevention of major complication .The purpose of study will identify risk factors for more severe juvenile RRP through prospective evaluation of a pediatric population in Thailand by the employing a protocol that includes staging of disease severity , as well as HPV genotyping.

Objective:

To identify the genotypes of HPV isolated from Thai RRP patients
To compare staging and severity with HPV genotypes
To correlate the following characteristics of the Thai RRP patients with the HPV genotypes

Eligibility

Ages Eligible for Study:	up to 18 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No
Sampling Method:	Probability Sample

Study Population

Target enrollment will be all children who are diagnosed with RRP.

Criteria
