© 2015 Arsenijevic et al. Background: Hydraulic dilatation is a novel method of cervical dilatation that is based on continuous controllable dilatation (CCBD) by the pumping of fluid into the balloon extension of the system. The main advantage of this procedure is that it allows control of and insight into the process of cervical dilatation. Methods: For the purposes of our research, we created a new and upgraded system for CCBD which consists of a programmed hydrostatic pump connected to a balloon extension. With regard to our aim to precisely measure and determine the location of the cervical resistance, we placed two pressure-measuring films, one on the top and one on the bottom of the balloon extension. This study included 42 patients in whom cervical resistance was measured before suction curettage. Results: Cervical dilatation and measurement of cervical resistance were successful in all patients. The analysis of the pressure-measuring films showed that the points of highest resistance were located in the zone of the internal cervical os and that these values were much higher than those in the zone of the external cervical os (0.402 versus 0.264 MPa at the upper pressure-sensitive film; 0.387 versus 0.243 MPa at the lower pressure-sensitive film). This study also showed that an increase in cervical resistance in the zone of the internal cervical os was followed by an increase in cervical resistance in the zone of the external cervical os. Conclusions: During CCBD, the internal cervical os is the centre of cervical resistance, and the values do not decline with the number of miscarriages or the number of previous births.

(2020) Vuletic, Milena; Jancic, Snezana; Milenković V.; Paunovic, Marinko; Miličić B.; Jancic N.; Perunicic B.; Slović, Živana
© 2020 The Authors Adipokine leptin functions through its transmembrane receptors (LEPR). In many malignant tumors it stimulates the growth, migration and invasion of malignant cells. The aim of our work is to examine the effect of LEPR expression on the clinical-morphological properties of squamous cell carcinoma of the skin (cSCC). The biopsy material obtained by excision of squamous cell skin cancer was used. The test group consisted of excision biopsies of squamous cell carcinoma of the skin (n = 62), and the control group (n = 62) consisted of excision biopsies of non-tumor tissue of the skin (from the tumor environment) from an operative preparation delivered to the Pathohistology Department. After routine processing and paraffin molding, histochemical Hematoxylin-Eosin and immunohistochemical ABC method with anti LEPR and Ki67 antibodies were applied at 4 μm sections. The statistical software package SPSS for Windows (26.0) was used to analyze obtained results. Intracytoplasmic and intramembranous LEPR expression was found in 100 % of examined cSCCs. LEPR expression was statistically significantly associated with proliferation index and histologic grade of tumors. Pronounced LEPR expression was associated with a high proliferation index in 66.7 % of cases and with poorly differentiated cSCC in 94.4 %. Multivariate regression analysis showed that cSCCs with pronounced LEPR expression were seven times more often poorly differentiated than tumors with moderate or LEPR expression in trace. Our results indicate that LEPR expression is a predictor of the malignant potential of cSCC, so that based on LEPR expression, it is possible to identify an aggressive cSCC phenotype, which provides the possibility of individualizing anti-tumor treatment using LEPR antagonists.

(2016) Djordjevic V.; Jovanovic M.; Miličić B.; Stefanovic V.; Djukić Dejanović S.
© 2016, Institut za Vojnomedicinske Naucne Informacije/Documentaciju. All rights reserved. Background/Aim. It is considered that over 450 million people worldwide suffer from some form of mental disorder. Previous studies in other countries have shown that schizophrenia is among the most frequent. Oral health is significant for general health and should not be separated from mental health. Studies in other countries have shown an increased incidence of carious and extracted teeth, and less incidence of filled teeth in this group of psychiatric patients. The aim of this study was to establish condition of the existing teeth, to determine the prevalence of caries and to consider possible risk factors that contribute to the current oral health status of hospitalized patients with schizophrenia. Methods. The study comprised 190 patients with schizophrenia, hospitalized at the Clinic for Psychiatric Disorders Dr. Laza Lazarević in Belgrade, and 190 mentally healthy patients at the Clinic for Periodontology and Oral Medicine, Faculty of Dental Medicine in Belgrade. The decayed, missing, filled (DMF) index, sociodemographic and economic characteristics were registered in both groups, as well as characteristics of the primary disease of hospitalized patients with schizophrenia. Results. The value of DMF index (representing the sum of carious, extracted and filled teeth), in the hospitalized patients with schizophrenia was 18.57 ± 7.07 and 12.47 ± 5.64 in the healthy group (p = 0.000). The structure of the DMF index in the study group showed that caries and extracted teeth dominated with 88.1%; in the control group, filled teeth dominated with 55.6%, which was a statistically significant difference for all the three observed variables. Conclusion. Hospitalized patients with schizophrenia had twice as many caries and extracted teeth, and five time less filled teeth than healthy people. The patient’s age and taking antiparkinsonics were established as predictors of the increased DMF index in hospitalized patients with schizophrenia.

(2013) Kalezić N.; Stojanovic, Mirjana; Ladjevic N.; Markovic D.; Paunović I.; Palibrk I.; Miličić B.; Sabljak V.; Antonijevic V.; Ivanovic B.; Ugrinović, Đorđe; Zivaljevic, Vladan
Background: Hypotension is a common adverse effect of IV anaesthetics, especially during the induction of anaesthesia. The aim of our study was to determine the incidence and risk factors for intraoperative hypotension (IOH) in thyroid surgery, as well as to determine whether and to what extent IOH affects the occurrence of postoperative hypotension. Material/Methods: The study included 1252 euthyroid patients, ASA 2 and ASA 3 status (American Society of Anesthesiologists physical status classification), who had thyroid surgery between 2007 and 2011. IOH was defined as a decrease in systolic blood pressure of >20% of baseline values. We studied the influence of demographic characteristics (sex, age, body mass index-BMI), comorbidity, type and duration of surgery, and anaesthesia on the occurrence of IOH. Univariate and multivariate logistic regression were used to determine predictors of occurrence of IOH. Results: IOH was registered in 6.5% of patients. The most common operation was thyroidectomy. Patients with IOH were younger, had lower BMI, and significantly less often had hypertension as a coexisting disease. The multivariate regression model identified BMI and the absence of hypertension as a coexisting disease, and as independent predictors of occurrence of IOH. Significantly more patients with IOH had postoperative hypotension (9.9% vs. 2.4%, p=0.000). Conclusions: IOH is common, even during operations of short duration and with minimal bleeding. It is necessary to pay special attention to these patients, given that many of these patients remained hypotensive during the postoperative period. © Med Sci Monit.

(2022) Jotic, Ana; Opankovic A.; Radin Z.; Cvorovic L.; Savić Vujović K.; Krejovic-Trivic S.; Bukurov B.; Miličić B.; Stojanovic, Jasmina
Purpose Persistent symptoms of chronic otitis media cause limitations in daily routine and social interactions, influencing significantly patients' quality of life and mental health. The purpose of the study was to assess the intensity depression, anxiety and stress symptoms in patients with chronic otitis media and to examine if patient demographic data, characteristics and reported symptoms of otitis influence reported depression, anxiety and stress symptoms. Material and methods The study included 316 adult patients diagnosed with unilateral or bilateral chronic otitis media with or without cholesteatoma. Patients underwent a complete otological, audiological and radiological assessment. Chronic otitis media questionnaire 12 (COMQ-12) was used to assess the impact of COM and Depression Anxiety Stress Scale 21 (DASS-21) was used for depression, anxiety and stress assessment. Results Some level of anxiety and stress were detected in 70.57% 49.37% of the patients, respectively. 13.29% of the patients had scores indicating depression disorder. The mean value of the COMQ-12 questionnaire for this group of patients was 26.24 (SD±11.47) More intense symptoms of COM were significantly associated (p<0.05) with higher scores on DASS-21 subscales. Multivariate logistic regression analysis indicated that significant positive predictors of higher anxiety scores were pure tone average (PTA) on better and worse hearing ear (p<0.05). Drainage from the ear, hearing problems at home and tinnitus were significant positive predictors of a higher DASS-depression score. (p<0.05) Conclusion The study confirmed positive correlation between reported level of anxiety, depression and stress, severity of COM symptoms and quality of life. Level of hearing on the better and worse hearing ear were significant positive predictors of anxiety and stress in patients with COM.

(2022) Zivkovic M.; Stefanovic, Neda; Glisic, Branislav; Brajovic, Gavrilo; Miličić B.; Kostić, Marija; Popović, Branka
The goal of this study was to examine the prevalence of WNT10A and RUNX2 mutations and assess their potential impact on the phenotype of non-syndromic tooth agenesis. The study included 30 participants with non-syndromic tooth agenesis, divided into hypodontia (n = 24) and oligodontia forms (n = 6), and 42 unaffected family members. Genomic DNA from buccal epithelial cells was used for polymerase chain reaction amplification of functionally important exons of the WNT10A and RUNX2 genes. Direct sequencing reactions were performed to confirm the presence of mutations. The trend of increasing prevalence of WNT10A mutations and a slight increase in the prevalence of RUNX2 mutations were revealed in tooth agenesis cases compared to unaffected family members. There was a higher prevalence of hypodontia than oligodontia, increased frequency of females over males with missing teeth, and a wide phenotypic variability was observed in individuals and families analyzed. The common missense mutations (p.Phe228Ile, p.Arg113Cys, p.Asp217Asn, and p.Gly165Arg) and c.114-56T>C in the WNT10A gene and in-frame-deletion/insertions (11A, 24Q, 30Q), synonymous variant c.240G>A, and 424-33dupC in the RUNX2 gene were identified. These findings highlight an important role of WNT10A and RUNX2 mutations in the genetic etiology of non-syndromic tooth agenesis.
