Various treatment of papillomatosis in dogs have been described: oral azithromycin [33], cimetidine [6], etretinate [22] and human recombinant interferon-α 2a [27], intramuscular Propionibacterium acnes [21], intravenous taurolidine [3], subcutaneous live papillomavirus vaccine [4], topical applications of 5-fluorouracil or imiquimod and surgical excision, crushing laser surgery or cryosurgical...

Biliary papillomatosis is exceedingly rare. Only sporadic cases were reported since the first description of this disease by Caroli in 1959. The disease is characterized by multiple and recurrent papillary adenoma in the biliary tree. Jaundice and cholangitis are ususally the main presenting symptoms. Although biliary papillomatosis is generally considered a benign disease, varying degree of dy...

Bioptic specimens from 224 melanocytic naevus lesions and 121 seborrheic keratosis lesions were stained with hematoxylin-eosin and examined under the light microscope. Pityrosporum ovale/orbiculare (Malassezia furfur) was found in 35% of melanocytic naevi and in 36% of seborrheic keratoses. The finding of Pityrosporum ovale/orbiculare was confirmed by PAS (periodic acid shift), methenamide silv...

Reticulate evolution is thought to accelerate the process of evolution beyond simple genetic drift and selection, helping to rapidly generate novel hybrids with combinations of adaptive traits. However, the long-standing dogma that reticulate evolutionary processes are likewise advantageous for switching ecological niches, as in microbial pathogen host switch events, has not been explicitly tes...

We studied the association between environmental stress and epidermal papillomatosis of roach Rutilus rutilus L. in Finnish waters using a 'matched pairs' design. Populations impacted by industrial and/or sewage effluents were compared to reference populations from pristine sites. We examined both the prevalence (proportion of diseased fish) and intensity (number of scales covered by tumors) of...

Biliary papillomatosis (BP) is a rare disease characterized by multiple numerous papillary adenomas in both the intrahepatic and extrahepatic biliary tree. Due to its high recurrence rate and frequent transformation to malignancy, BP should not be considered a benign disease, and a radical resection with an adequate resection margin is advocated in cases of localized intrahepatic biliary papill...

Reticulate evolutionary processes result in phylogenetic histories that cannot be modeled using a tree topology. Here, we apply methods from topological data analysis to molecular sequence data with reticulations. Using a simple example, we demonstrate the correspondence between nontrivial higher homology and reticulate evolution. We discuss the sensitivity of the standard filtration and show c...

A squamous papilloma which occluded the trachea of a young man was managed by resection at tracheotomy. Thereafter it was possible further to examine the bronchi bronchoscopically, and widespread papillomatosis confined to the left bronchi was seen. Following bronchography, which showed left-sided bronchiectasis, left pneumonectomy was undertaken. Case details are presented and the literature w...

OBJECTIVES To describe our management of complex glottic stenosis in tracheotomy dependent children with severe recurrent respiratory papillomatosis. METHODS Retrospective chart review at a tertiary care children's hospital. RESULTS Three children with complex glottic stenosis secondary to severe recurrent respiratory papillomatosis were treated at our institution since 2011. Two patients h...
