[Characteristic of iatrogenic odontogenic sinusitis]. / Kharakteristika yatrogennykh odontogennykh gaimoritov.

OBJECTIVE: The aim of the study was to study the structure of odontogenic sinusitis and identify iatrogenic etiological factors. MATERIAL AND METHODS: A retrospective analysis of the case histories of patients operated from 2015 to 2019 with a diagnosis of «Sinusitis¼ in the Clinical City Emergency Hospital in Tashkent, Republic of Uzbekistan in the department of emergency maxillofacial surgery was carried out. The total number of patients was 333 people: 105 (31.5%) men and 228 (68.5%), the average age of patients was 39.4 years. RESULTS: When analyzing the reasons for the development of sinusitis, in 73% of the total number of operated patients, there was an associated lesion of the teeth. When detailing the sources of odontogenic infection, it was determined that periapical foci of inflammation (granulomatous, granulating periodontitis, cystogranulomas) accounted for 26%, foreign bodies (teeth, roots of teeth, filling materials removed into the maxillary sinus during endodontic treatment) 31%, fistulous passages after removal teeth and attempts to eliminate perforation by surgery 43%. Other etiological factors were found: chronic polypous rhinosinusitis 14%, benign tumors 8%, allergic fungal sinusitis 5%. CONCLUSION: Clinical analysis showed that the development of most cases of odontogenic sinusitis is associated with the mistakes of dentists and is of iatrogenic origin. To prevent the development of odontogenic iatrogenic sinusitis, prior to dental interventions on the teeth of the upper jaw, it is necessary to carry out a topical diagnosis of their ratio with the maxillary sinus.

[Age-related characteristics of the changes in the activity of the enzymes that implement cavity and membrane carbohydrate hydrolysis in stress]. / Vozrastnye osobennosti izmenenii aktivnosti fermentov, realizuiushchikh polostnoi i membrannyi gidroliz uglevodov pri stresse.

A response of the rat carbohydrate systems of the digestive organs to different stressful factors was shown to depend on their age: it is obvious in 7- to 16-day-old rats and disappears completely by the 30th day of age. It reappears after hormonal administration in 21-day-old rats, whereas in 3-day-old rats no response to the stress or Th injection occurs.
