[Primordial odontogenic tumor in children]. / Pervichnaya odontogennaya opukhol' u detei.

Primordial odontogenic tumor (POT) is a rare benign mixed epithelial and mesenchymal odontogenic tumor that has been included as a new nosological form in the latest classification of the World Health Organization (WHO 2017). The first two clinical cases of POT treatment in children in Russia are presented. A comprehensive examination and surgical treatment of POT were carried out. The diagnosis was confirmed morphologically. OBJECTIVE: To inform maxillofacial surgeons and dentists about the clinical, radiological and morphological features of POT on the example of clinical experience and literature data.

[A complex approach to the differential diagnosis of chronic parenchymal parotitis in children]. / Kompleksnyi podkhod v differentsial'noi diagnostike khronicheskogo nespetsificheskogo parenkhimatoznogo parotita u detei.

BACKGROUND: Chronic parenchymal parotitis is the most common salivary gland disease in children which occurs in about 85% cases. Diagnosis errors in chronic parenchymal parotitis are frequent and important but represent an underemphasized and understudied area of patient safety. OBJECTIVE: The objective of this study was to elaborate the most effective and acceptable strategies for the diagnosis of chronic parenchymal parotitis in children. MATERIAL AND METHODS: We studied the histories of 211 patients with a primary diagnosis of chronic parenchymal parotitis. All patients underwent ultrasound diagnostic, as well as medical and genetic counseling and examination of 1st degree relatives and probands. RESULTS: After additional examinations, 100 children were given other diagnoses. Having analyzed the results of medical-genetic and echographic examinations of 111 patients with chronic parenchymal parotitis and their family members, we have developed a pattern of chronic parenchymal parotitis inheritance. All patients were divided into 3 groups according to the type of inheritance: monogenic inheritance, multifactorial inheritance, and sporadic cases. CONCLUSION: A complex approach to the differential diagnosis of chronic parenchymal parotitis is what is needed to reduce the frequency of diagnostic errors.

[Sialendoscopy in diagnosis and treatment of salivary gland disorders]. / Sialoendoskopiya v diagnostike i lechenii patologii slyunnykh zhelez.

Sialendoscopy is a relatively new and progressive procedure that allows endoscopic transluminal visualization of major salivary glands and offers a mechanism for diagnosing and treatment of both inflammatory and obstructive pathology related to the ductal system. Several authors have stressed the striking role of sialendoscopy in prevention of juvenile recurrent parotitis. However, the emerging use of sialendoscopy in juvenile recurrent parotitis has not been critically analysed. The objective of our review is to overview the existing literature with particular regards to diagnostic and therapeutic outcomes after the application of sialendoscopy.
