MORPHOLOGICAL FEATURES OF MAXILLARY SINUS CYSTS BASED ON THE STUDY OF PARTICULAR HISTOCHEMICAL AND IMMUNOHISTOCHEMICAL FACTORS OF INFLAMMATION.

Objective: The aim: To study the morphological structure and immunohistochemical markers of inflammatory cells in the maxillary sinus cyst wall.

Patients And Methods: Materials and methods: Biopsy samples of maxillary sinus cysts of 92 operated patients aged 18 to 74 years were studied. We used standard staining with hematoxylin and eosin, PAS reaction, and immunohistochemical analysis with monoclonal antibodies to CD68 (macrophages) and CD3 (T- lymphocytes) to determine morphological features and severity of inflammation and PanCK AE1/AE2 antibodies to identify epithelium state.

IMPACT OF THE NASAL VALVE SHAPE ON THE OLFACTORY FUNCTION AND SUBJECTIVE PERCEPTION OF THE NASAL BREATHING.

Objective: The aim: To study the impact of the internal nasal valve shape on respiratory and olfactory nose function as well as on quality of life.

Patients And Methods: Materials and methods: The study involved 17 volunteers who noted satisfaction of nasal breathing in the absence of changes during endorhinoscopy. The study was con¬ducted in two stages: stage 1 involved assessing initial indicators of quality of life by the SNOT-22 questionnaire, performing active anterior rhinomanometry, and estimating the olfactory function (Sniffin' Sticks); stage 2 consisted in re-assessing the mentioned indicators after changing the shape and lumen of the internal nasal valve.

MOLECULAR EPIDEMIOLOGY OF THE TRANSMISSION OF METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS IN KYIV ACUTE CARE HOSPITALS, UKRAINE.

Objective: The aim: To evaluate the potential of transmission of methicillin-resistance Staphylococcus aureus (MRSA) in Ukrainian acute care hospitals.

Patients And Methods: Materials and methods: We performed a multicenter cross-sectional study. Definitions of HAI were used from the CDC/ NHSN.

BACTERIAL INFECTION CAUSES OF PREGNANCY LOSS AND PREMATURE BIRTH IN THE WOMEN IN UKRAINE.

Objective: The aim: To find out whether or not the presence of pregnancy loss and preterm birth was associated with the history of healthcare-associated infection (HAI) of women reproductive tract.

Patients And Methods: Materials and methods: We performed a retrospective cohort study was based on surveillance data. This study included 1,027 fertile women aged 21-50 years admitted to 8 hospitals from 2017-2019 with complaints to pregnancy loss or preterm birth.

PREVALENCE OF NASAL CARRIAGE OF METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS AMONG HEALTHCARE WORKERS IN THE DEPARTMENTS OF OTORINOLARYNGOLOGY AND DENTISTRY IN KYIV, UKRAINE.

Objective: The aim: To obtain the first estimates of the current prevalence of nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) among healthcare workers (HCWs) in the departments of Otorinolaryngology and Dentistry and to determine of genes virulence factors (Panton Valentine Leukocidine (PVL) genes).

Patients And Methods: Materials and methods: We performed a multicenter cross-sectional study. The susceptibility to antibiotics was determined by disk diffusion method according to the European Committee on Antimicrobial Susceptibility Testing.

Bloodstream infections and antimicrobial resistance of responsible pathogens in Ukraine: results of a multicenter study (2013-2015).

Objective: Introduction: Bloodstream infections (BSIs) are associated with high morbidity and mortality worldwide. However data of BSI from Ukraine are scarce. The aim: To obtain the first national estimates of the current incidence of BSI and antimicrobial resistance of responsible pathogens, and associated mortality in Ukraine.

Antimicrobial resistance of staphylococcus aureus causing of surgical site infections in ear, nose and throat surgery.

Objective: Introduction: Staphylococcus aureus is one of the major pathogens that causes of surgical site infection (SSI). Scant information is available on the occurrence and antimicrobial susceptibility of S. aureus in patients with SSI in Ear, Nose and Throat (ENT) surgery.
