Recurrent respiratory papillomatosis (RRP), which is caused by human papillomavirus types 6 and 11, is the most common benign neoplasm of the larynx among children and the second most frequent cause of childhood hoarseness. After changes in voice, stridor is the second most common symptom, first inspiratory and then biphasic. Less common presenting symptoms include chronic cough, recurrent pneu...

Two intraperitoneal injections of either infectious or non-infectious rabbit papilloma suspensions actively immunize rabbits against papillomatosis. The capacity of the non-infectious suspensions to immunize is considered as evidence that they contain papilloma virus even though none can be demonstrated by the usual infection test.

In children, benign neoplasms of extrahepatic biliary ducts are extremely rare. We report a case of 3 year old girl who presented with abdominal pain and jaundice for 6 months. The final diagnosis on histopathology was papillomatosis in lower common bile duct.

BACKGROUND The role of human papillomaviruses (HPV) in the development of squamous cell carcinoma (SCC) has been established for anogenital lesions but still remains controversial for carcinomas in other sites. The aim of this study was to determine the α-HPV and β-HPV prevalence and their association with p16 expression, sun exposure, and clinicopathological findings in patients with Bowen's d...

OBJECTIVES To measure human papillomavirus (HPV) 6 and 11 viral load and antibody response in longitudinal specimens obtained from children with recurrent respiratory papillomatosis and to examine the association of type-specific viral load with clinical severity of disease. DESIGN Longitudinal pilot study with a median follow-up of 5.4 months. SUBJECTS The study included 15 children underg...

OBJECTIVE To determine whether DNA ploidy and the S-phase fraction are predictive of the clinical course in children with recurrent respiratory papillomatosis. DESIGN Masked compression of DNA analysis findings to the clinical course of the disease. SETTING Tertiary referral center. PATIENTS All pediatric patients treated for recurrent respiratory papillomatosis at our institution between...

This study describes the clinical, histopathological, and virological characterization of teat papillomatosis from Brazilian dairy cattle herds. Four types of bovine papillomavirus were identified (BPV6, 7, 9, and 10); one of these (BPV7) is being detected for the first time in Brazilian cattle.

Canis familiaris oral papillomavirus, formerly canine oral papillomavirus, is a causative agent of the self-resolving canine oral papillomatosis and was first described in 1994. This is the first report of two full-length genome sequences described in South Africa and indicates the highly conserved nature of Canis familiaris oral papillomavirus.

A divergent human papillomavirus (HPV), isolated from a lung lesion of a patient with recurrent respiratory papillomatosis, was fully cloned, sequenced, and genetically characterized. DNA analysis revealed that the HPV contained a 10.4-kb genome, with a duplication of 2,493 bp that includes partial L1-long control region (LCR)-E6-E7-partial E1 sequences.

Papillomatosis is a condition in farm animals and is treated by surgical excision or application of certain caustic agents. Contrary to it, two cattle with teat warts were treated by an alternative method by using the thuja occidentalis (thuja-30, a homeopathic medicine) @ 10 drops Per os twice a day for a span of 3 weeks and lead to complete recovery.
