    Background/Aim. Anatomical parameters of the bony components of the hip joint are essential for better under- standing of etiopathogenesis of diseases like primary osteo- arthrosis of the hip joint. The aim of this reserch was to ex- amine the normal acetabular morphometry in Serbian popu- lation and to determine whether there are sex differences in anatomical parameters of the acetabulum among asympto- matic subjects. Methods. Pelvic radiographics of 320 adult asymptomatic patients (640 hips) were analyzed in 170 men and 150 women to determine the morphology of the ace- tabulum in Serbian population. For each hip the center edge angle of Wiberg (CEA), the acetabular angle of Sharp (AA), acetabular depth (AD), acetabular roof obliquity (ARO) and roof angle (RA) were measured. Results. The following aver- age measurements for acetabulum geometry were obtained (x ± SD): CEA - 33.5 ± 6.5° (33.6 ± 5.8° in male, 33.3 ± 6.9° in female), AA - 38.0 ± 3.8° (37.5 ± 3.6° in male, 38.5 ± 3.9° in female), AD - 11.9 ± 2.8 mm (12.5 ± 2.7 mm in male, 11.2 ± 2.7 mm in female), ARO - 7.6 ± 5.7° (6.2 ± 4.9° in male, 9.0 ± 6.0° in female) and RA - 18.4 ± 10.0° (19.6 ± 8.5° in male, 17.1 ± 9.5° in female). There were significant differences in the CEA, AA, AD, ARO and RA related to gender (p < 0.01, t-test). Conclu- sion. There are significant gender differences in Serbian population for all the examined anatomical parameters of acetabulum. We found sex-related differences in acetabular morphology, female acetabulum being marginally more dys- plastic than male acetabulum. There is also a clear tendency of female hips to be more dysplastic than male ones

    Background/Aim. Nucleus accumbens is a part of the ventral striatum also known as a drug active brain region, especially related with drug addiction. The aim of the study was to investigate the Golgi morphology of the nucleus accumbens neurons. Methods. The study was performed on the frontal and sagittal sections of 15 human brains by the Golgi Kopsch method. We classified neurons in the human nucleus accumbens according to their morphology and size into four types: type I - fusiform neurons; type II - fusiform neurons with lateral dendrite, arising from a part of the cell body; type III - pyramidal-like neuron; type IV - multipolar neuron. The medium spiny neurons, which are mostly noted regarding to the drug addictive conditions of the brain, correspond to the type IV - multipolar neurons. Results. Two regions of human nucleus accumbens could be clearly recognized on Nissl and Golgi preparations each containing different predominant neuronal types. Central part of nucleus accumbens, core region, has a low density of impregnated neurons with predominant type III, pyramidal-like neurons, with spines on secondary branches and rare type IV, multipolar neurons. Contrary to the core, peripheral region, shell of nucleus, has a high density of impregnated neurons predominantly contained of type I and type IV - multipolar neurons, which all are rich in spines on secondary and tertiary dendritic branches. Conclusion. Our results indicate great morphological variability of human nucleus accumbens neurons. This requires further investigations and clarifying clinical significance of this important brain region

    The human subiculum is a significant part of the hippocampal formation positioned between the hippocampus proper and the entorhinal and other cortices. It plays an important role in spatial navigation, memory processing and control of the response to stress. The aim of our study was identification of the morphometric characteristics of the neurons of the human subiculum proper: the maximum length and width of cell body and total dendritic length and volume of cell body. Comparing the measured parameters of different types of subicular neurons (bipolar, multipolar, pyramidal neurons with triangular-shaped soma and neurons with oval-shaped soma), we can conclude that bipolar neurons have the lowest values of the measured parameters: the maximum length of their cell body is 14.1 ± 0.2 μm, the maximum width is 13.9 ± 0.5 μm, and total dendritic length is 14597 ± 3.1 μm. The lowest volume value was observed in bipolar neurons; the polymorphic layer is 1152.99 ± 662.69 μm 3. The pyramidal neurons of the pyramidal layer have the highest value for the maximal length of the cell body (44.43 ± 7.94 μm), maximum width (23.64 ± 1.89 μm), total dendritic length (1830 ± 466.3 μm) and volume (11768.65±4004.9 μm 3) These characteristics of the pyramidal neurons indicate their importance, because the axons of these neurons make up the greatest part of the fornix, along with the axons of neurons of the CA1 hippocampal field

    The aim of this investigation was to examine normal acetabular morphometry, its sex dimorphism and the acetabular dysplasia rate in Serbian adults. For each hip, the centre-edge angle of Wiberg, the acetabular angle of Sharp, acetabular depth and acetabular roof obliquity were measured. The center-edge angle of Wiberg correlated negatively with the acetabular angle of Sharp and acetabular roof obliquity, but positively correlated with acetabular depth. Our results suggest that the prevalence of acetabular dysplasia in the Serbian population is lower than in Western countries. We confirmed the existence of significant gender differences in acetabular morphology among the subjects of our study. These sex-related differences in acetabular morphology were the cause for more dysplastic female acetabula compared with male acetabula

    Objectives: To identify risk factors that contribute to the occurrence of fetal growth restriction (FGR) and small for gestational age (SGA) and quantify the strength of their impact. Material and methods: This study was designed as a retrospective-prospective observational cohort study conducted on pregnant women at the Clinic for Gynecology and Obstetrics at the University Clinical Centre Kragujevac, Serbia. We measured the intrauterine degree of fetal development through the estimated fetal weight (EFW) on ultrasound examination, which was calculated using Hadlock’s formula 3. Fetuses whose EFW was below the 10th percentile on the World Health Organization (WHO) fetal growth charts adjusted for gender and gestational age were classified as FGR fetuses, while newborns weighing less than the 10th percentile were considered SGA. Results: The study included 320 pregnant women with an average age of 30.3 ± 5.5 years who gave birth to 332 newborns. The results of univariate and multivariate stepwise backward conditional binary logistic regression showed that the occurrence of FGR during the second trimester was more likely in pregnant women with lower body height and proteinuria. The risk factors for the occurrence of FGR during the third trimester were lower body height and proteinuria, while iron supplementation had a protective effect. SGA newborns were more common in pregnant women who were shorter, had proteinuria, used corticosteroids, or smoked during pregnancy. Conclusions: Clinicians should pay special attention to pregnant women with lower body height, proteinuria, who smoke and use corticosteroids in order to prevent FGR and SGA

    The aim of this study was to determine the nasal parameters in the population of central Serbia and to compare them with those determined in earlier studies in different populations. The research was conducted on 496 randomly selected persons (262 males and 234 females), aged 18-65 years. The measured parameters were nasal height and nasal breadth and the standard spreading caliper with scale was used for measurements. There were significant differences in the nasal parameters between male and female subjects. The nasal breadth was 34.72 mm in females, and in the male population it was 36.7 mm. The mean values of nasal height were 52.6 mm and 54.32 mm in females and males, respectively. The nasal index in females and males was 66.01 and 67.56, respectively, and the mean value of the nasal index of all respondents was 66.78. After conducting the research it was concluded that the dominant nasal type in the population of the central part of Serbia is leptorrhine. The present study showed the existence of sexual dimorphism in nasal morphology. The data obtained in our study may be useful in anthropological and forensic research, as well as in cosmetic planning and reconstructive surgery

    The aim of this study was to detect and describe the existence and incidence of anatomical variations of the celiac trunk and superior mesenteric artery. The study was conducted on 150 persons, who underwent abdominal Multi- Detector Computer Tomography (MDCT) angiography, from April 2010 until November 2012. CT images were obtained with a 64-row MDCT scanner in order to analyze the vascular anatomy and anatomical variations of the celiac trunk and superior mesenteric artery. In our study, we found that 78% of patients have a classic anatomy of the celiac trunk and superior mesenteric artery. The most frequent variation was the origin of the common hepatic artery from the superior mesenteric artery (10%). The next variation, according to frequency, was the origin of the left gastric artery direct from the abdominal aorta (4%). The arc of Buhler as an anastomosis between the celiac trunk and superior mesenteric artery, was detected in 3% of cases, as was the presence of a common trunk of the celiac trunk and superior mesenteric artery (in 3% of cases). Separate origin of the splenic artery and the common hepatic artery was present in 2% of patients. The MDCT scanner gives us an insight into normal anatomy and variations of the abdominal blood vessels, which is very important in the planning of surgical interventions, especially transplantation, as well as in the prevention of complications due to ischemia

    The aim of this study was to determine the craniofacial parameters in the population of the central part of Serbia. The research was conducted on 700 persons (360 males and 340 females), aged 18-65 years, selected randomly. The measured parameters were morphological facial height and breadth. The standard spreading caliper with scale was used for the measurement of facial parameters. There were significant differences in the facial parameters of male compared to female subjects in all observed parameters. The mean value of the morphological facial height in the study population was 116.8 mm ± 7.28, maximum facial breadth 124.12 mm ± 8.44, while the mean value of the total facial index was 93.68 ± 6.86. The total facial index was calculated according to the formula and the obtained results were analyzed statistically using the t-test. The dominant phenotype in the studied population was leptoprosopic. The data obtained in our study may be useful in anthropological research, forensics, genetic research, as well as in medical clinical practice

    Background: Human monkeypox was a neglected zoonotic disease considered endemic to rainforests of rural parts of Central and Western Africa, until a global outbreak in May 2022. Methods: This review describes the epidemiological characteristics of human monkeypox. Results: Since the first confirmed case in the United Kingdom on 13 May 2022, and up until 19 September, more than 62,000 cases of human monkeypox were reported in 104 countries in the world (among them 97 countries where the monkeypox virus was not endemic). Up to today, 20 persons have died in this global outbreak. This outbreak predominantly affects men self-identifying as gay or bisexual or other men who have sex with men, and for now, there is no sign of continuous transmission of the disease in other populations. Today, the monkeypox outbreak is increasing alarmingly in many countries and presents a new challenge and a large issue for public health worldwide. The World Health Organization declared the global monkeypox outbreak a public health emergency of international concern on 24 July 2022. Before this outbreak, health professionals in many countries had a knowledge gap and a lack of experience in the management of monkeypox. Conclusions: Advances in the comprehension of the epidemiology of human monkeypox are necessary for effective prevention and outbreak response

    Objectives: This paper reports association between mortality rates from cancer, ischaemic heart disease and diabetes mellitus and the consumption of common food groups and beverages in Serbia. Design: In this ecological study, data on both mortality and the average annual consumption of common food groups and beverages per household's member were obtained from official data-collection sources. The multivariate linear regression analysis was used to determine the strength of the associations between consumption of common food groups and beverages and mortality rates. Results: Markedly increasing trends of cancer, ischaemic heart disease and diabetes mellitus mortality rates were observed in Serbia in the period 1991-2010. Mortality rates from cancer were negatively associated with consumption of vegetable oil (p=0.005) and grains ( p=0.001), and same was found for ischaemic heart disease (p=0.002 and 0.021, respectively), while consumption of other dairy products showed a significant positive association (p<0.001 and p=0.032, respectively). In men and women, mortality rates from diabetes mellitus showed a significant positive association with consumption of poultry (p=0.014 and 0.004, respectively). Consumption of beef and grains showed a significant negative association with cancer mortality rates in both genders (p=0.002 and p<0.001 in men, and p<0.001 and p=0.014 in women, respectively), while consumption of cheese was negatively associated only in men ( p<0.001). Mortality from diabetes mellitus showed a significant positive association with consumption of animal fat and other dairy products only in women (p=0.003 and 0.046, respectively). Conclusions: Association between unfavourable mortality trends from cancer, ischaemic heart disease and diabetes mellitus, and common food groups and beverages consumption was observed and should be assessed in future analytical epidemiological studies. Promotion of healthy diet is sorely needed in Serbia
