Abstract Acetowhite epithelium (AWE) is one of the main clinical indicator of papillomavirus infection in squamous cell lesions. AWE has a different intensity in various degree of the cervix papillomavirus infection. The digital approach gives the opportunity to estimate AWE intensity by numeric values. The investigation aim is a quantitative assessment of cervical surface changes in papillomavirus infection with digital analysis and computer technologies. The spread of AWE on the cervical surface area has a value of the cervix papillomavirus infection in squamous cell lesions. These two features provide to create the index intensity (IndInt) and index grey value (IndGV). Open-source software ImageJ was used to analysis of colposcopic images. The 8-bit mode was used for the estimation of the AWE grey value. The algorithm of digital analysis detected indicators that provide the severity of papillomavirus infection. The outcomes of an algorithm were the identification of the cervix surface condition severity by an objective quantification.

The investigation aims - a quantitative assessment of cervical surface changes with digital analysis and computer technologies in dysplasia. Colposcopy was made in 90 women from 21 to 52 years (avr. age 33,9±8,13 y.o.) with mild epithelial dysplasia (CIN1), moderate dysplasia (CIN2), severe dysplasia (CIN3). The algorithm detected indicators which provide the cervical dysplasia classification on pre cytological and pre molecular-genetic patients investigations. The outcome of an algorithm was the identification of the cervix surface condition severity by an objective quantification. The cervical dysplasia type (CIN) was classified as IndGV values. The mild dysplasia (CIN1) had IndGV=8,5, moderate dysplasia (CIN2) - IndGV=13, severe dysplasia (CIN3) - IndGV=15,6. The cervical affected surface area (IndInt) equalled 0,17 in CIN1, 0,19 in CIN2, 0,22 in CIN3. A change severity has a direct relation with a grey color value. It demonstrates quantify classification in digital analysis. The algorithm is used in real-time mode and no requires considerable material outlays. This makes it possible to use an algorithm after clinical examination and predict patient management.

A 3-week-old suckling piglet spontaneously died after septicemic colibacillosis. At postmortem examination, bulging and ulcerated lesions were seen, affecting the oral mucosa on the inner surface of the lower lip. After histopathological investigation, the diagnosis of congenital oral squamous cell carcinoma was made. To the best of our knowledge, this is the first case of congenital oral squamous cell carcinoma ever described. A relationship has been shown or suggested between papillomavirus infection and oral squamous cell carcinoma in humans and animals. However, next-generation sequencing study did not demonstrate any papillomavirus sequences in the case reported herein.
