Recently, there has been a steady growth of cervical cancer all over the world, especially in Russia. Patients with cervical cancer have become much younger. At the same time, the human papillomavirus is not only the main factor in the neoplastic process, but it is also one of the most common sexually transmitted infections in the world. The aim of the paper is to assess the prevalence and characteristics of human papillomavirus genotypes in patients with cervical intraepithelial neoplasia. Materials and Methods. During the periodic screening we examined 213 women of a reproductive age with HPV infection. All patients underwent liquid-based cytology and human papillomavirus genotyping by polymerase chain reaction. Results. We revealed that the prevalence of cervical intraepithelial neoplasia among women with papillomavirus infection was 80.3 % (n=171). According to human papillomavirus genotyping, HPV 16 (38 %) and HPV 33 (32 %) prevailed. We also observed positive high correlation between high-grade squamous intraepithelial lesions (HSIL) and HPV 18 (r=+0.759, p=0.001), a negative mean correlation between HPV 45 and low-grade squamous intraepithelial lesions (LSIL) (r=-0.643, p=0.002). A cohort of patients with severe intraepithelial cervical lesions demonstrated high viral load rates. Conclusion. According to the results obtained, we established the dominance of HPV 16 and HPV 33 genotypes in cervical intraepithelial neoplasia. There were significant differences between HSIL and LSIL patients with HPV 18 and HPV 45. There was also a correlation between an increase in the viral load with the severity of the pathological process. Keywords: human papillomavirus, intraepithelial cervical neoplasms, cervical cancer. В последние годы в мире, особенно в России, наблюдается неуклонный рост и «омолаживание» рака шейки матки. При этом вирус папилломы человека является не только основным фактором прогрессирования неопластического процесса, но и одной из наиболее распространенных инфекций, предаваемых половым путем, в мире. Цель. Оценить распространенность и характеристику генотипов папилломавирусной инфекции у пациенток с цервикальными интраэпителиальными неоплазиями. Материалы и методы. Проведено обследование 213 пациенток репродуктивного возраста с ВПЧ-инфекцией, пришедших на профилактический осмотр. Всем женщинам было выполнено цитологическое исследование жидкостным методом и генотипирование вируса папилломы человека методом полимеразной цепной реакции. Результаты. Распространенность цервикальных интраэпителиальных неоплазий среди женщин с папилломавирусной инфекцией составила 80,3 % (171 пациентка). Согласно данным генотипирования вируса папилломы человека превалировал 16-й (38 %) и 33-й типы (32 %). Выявлена положительная высокая корреляционная связь между цервикальными неоплазиями высокой степени онкогенного риска (HSIL) и 18-м типом ВПЧ-инфекции (r=+0,759 при р=0,001), отрицательная средняя корреляционная связь 45-го типа ВПЧ с низкой степенью онкогенного риска (LSIL) (r=-0,643 при р=0,002). Продемонстрированы высокие показатели вирусной нагрузки в когорте пациенток с тяжелыми внутриэпителиальными цервикальными поражениями. Выводы. По результатам полученных данных установлено доминирование 16-го и 33-го генотипов ВПЧ при цервикальных интраэпителиальных неоплазиях с наличием значимых различий между пациентами с HSIL и LSIL в отношении 18-го и 45-го типов, а также связь роста уровня вирусной нагрузки с увеличением степени тяжести патологического процесса. Ключевые слова: вирус папилломы человека, интраэпителиальные новообразования шейки матки, рак шейки матки.

The aim of the study was to assess the prevalence of DNA viruses (HSV I and II, CMV, EBV, HPV6.11, HPV16 and HPV18) in the native oral mucosa of healthy volunteers (n=50; 30 men (60.0%), 20 women (40.0%); 25—74 years, median age — 55.0 years (95% CI 47.60-56.76)). All samples of the normal oral mucosa were detected by real-time PCR to detect viral DNA. The majority of the examined — 76% (33/50) — revealed the DNA: one type of viral DNA in 17 (38.00%) of the examined, a combination of the two types in 14 (28.00%). In the normal oral mucosa, DNA of Epstein-Barr virus was significantly more often detected: 15 (30.00%) (p = 0.0276) and human papilloma viruses 27 (54.00%) (p <0.0001), especially HPV-18 (24 (48.00%)): mono-association in 9 (18.00%) examined and in 7 (14.00%) in combination with EBV DNA (p = 0.0253).

In order to emphasise the importance of histopathology in the clinically unsuspected diagnosis of duodenal strongyloidiasis, we report six cases diagnosed on duodenal biopsies identified from the database over a period of 15 years, and clinical, endoscopic and histopathological findings were analysed retrospectively. Four were elderly males and the remainder young females. Only one patient had an underlying immunocompromised state. Three presented with cholestatic jaundice and simulated hepatobiliary malignancy. In all cases, endoscopy provided non-specific findings. Only one case showed a predominant eosinophilic infiltrate. Eggs, larvae and adult forms of strongyloides were seen in crypts and showed intense basophilic staining on HE stain. It is concluded that since mostly undetected clinically, duodenal biopsy serves as the first step in the diagnosis of strongyloidiasis. Hepatobiliary manifestations, though very infrequent, should raise the suspicion for strongyloidiasis and thus necessitate the need for duodenal biopsy.

Rosai-Dorfman disease (RDD) is characterized histologically by a dense histiocytic infiltrate with emperipolesis and associated lymphocytes, plasma cells, and neutrophils. Eosinophils are not commonly associated. We report a patient with initial thymus and pituitary gland involvement by RDD, who later developed papules on the groin and axilla. Skin biopsies showed admixed histiocytic infiltrates (lymphocytes, neutrophils, and plasma cells) without emperipolesis. A prominent eosinophilic infiltrate was also observed, a feature not, to our knowledge, previously reported. Immunohistochemistry revealed positivity for CD68 (most cells) and S100 protein (scattered cells) and was negative for anti-CD1a. The diagnosis of RDD was established in the clinical context after comparison with the thymic and pituitary lesions (similar histologic features, albeit with fewer eosinophils, and immunohistochemical profiles). We present the first case, to our knowledge, of multicentric RDD with cutaneous involvement and associated prominent eosinophilic infiltrate. Thus, RDD should be included in the differential diagnosis of mononuclear infiltrates containing eosinophils.
