Introduction: Peptic ulcer is a chronic recurrent disease of the gastrointestinal tract, which most often occurs as gastric or duodenal ulcer. Peptic ulcer is characterized by certain geographical and temporal trends.

Objective: The aim of this study is to determine the frequency of gastric and duodenal ulcers among subjects who underwent esophagogastroduodenoscopy (EGDS) endoscopy due to dyspeptic complaints, as well as to analyze the trend of ulcer disease over a period of 10 years.

Material and Methods: The data of a total of 4074 subjects with an average age of 54.53 ± 15.03 years, both sexes, 1841 men and 2233 women, who underwent EGDS in 2005 and 2015 calendar years were retrospectively analyzed. Results: This study showed that the trend of ulcer disease significantly decreased in the observed ten-year period, accompanied by concomitant decrease in the prevalence of duodenal ulcers, while the frequency of gastric ulcers retained approximately at the same level. The results showed that men were at greater relative risk than women for the development of duodenal ulcers, in both calendar years. In the ten-year period, the average age of patients with ulcer disease increased by about 4 years, especially in the group with duodenal ulcer, and particularly within women with duodenal ulcer. Compared to 2005, the average age of subjects undergoing EGDS in 2015 increased by about 2 years, regardless of whether or not they were diagnosed with ulcer disease.

Conclusions: In the period 2005 - 2015, the age of patients with peptic ulcer tended to increase, whilst the prevalence of ulcer disease, especially duodenal ulcer, has decreased. The relative risk for duodenal ulcer in men was higher than in women. 

Introduction: Syncope is a sudden, short-lived, transient loss of consciousness associated with the inability to maintain postural tone. The aim of this paper is: to determine the frequency of syncope in children and adolescents in our conditions, to analyze the characteristics of syncopal episodes and clinical presentation in order to identify the etiology of seizures, and to provide diagnostic protocols, i.e. guidelines for streamlining clinical trials.

Methodology: The diagnosis of the disease was made clinically on the basis of well-taken anamnestic data and a detailed description of the quality of the attack, physical examination and routine laboratory analyzes: (CBC, glycemia, standard ECG). Additional tests were selectively performed: Holter ECG, ergometry, Tilt table test, Echocardiogram, NMR, EEG.

Results: Out of the total number of examined children in the outpatient Children’s Hospital, Department of Pediatric Cardiology, 139 patients (0.6%) reported due to short-term loss of consciousness. The largest number of children was between 15 and 18 years old. Ninety-two ( 66%) of those 139 were girls, and 47 (34%) were boys (p <0.05). Regarding the cause of syncope, it was found in 117 (84%) patients, and in 22 (16%) children the cause of syncope was unknown (p <0.05). Etiologically spreaking, syncope was divided into 3 groups: autonomic (vasovagal, situational, orthostatic, increased vagus tone in athletes) was the most common, in 88 patients (75%), cardiogenic in 5 (4%) and non-cardiogenic in 24 patients.(21%). There was also a recurrence of the attack. In two children, the syncopal attack was repeated 4 times.

CONCLUSION: Syncope most often occurs in teenagers and is mostly benign. To assess syncope, it is necessary to gather a detailed history of the attack, to conduct a detailed physical examination and routine laboratory analyzes: CBC, glycemia and standard ECG. Supplementary diagnostics should be performed exclusively in patients where there is a reasonable suspicion of heart disease or neurological diseases. 

Uvod: Dispepsija je čest gastroenterološki sindrom koji značajno narušava kvalitet života. Infekcija bakterijom Helicobacter pylori (H. pylori) ključni
 je faktor u razvoju organske dispepsije, dok njena povezanost sa funkcionalnom dispepsijom ostaje predmet istraživanja.
 Cilj: Ispitati prevalenciju H. pylori infekcije kod pacijenata sa dispepsijom i njenu povezanost sa simptomima, endoskopskim nalazima i hematološkim
 parametrima
 Metode: Retrospektivna studija obuhvatila je 117 pacijenata sa dispepsijom pregledanih tokom 2023. godine na Internoj klinici KBC Priština-Gračanica
 u Lapljem Selu. Svi su podvrgnuti gornjoj gastrointestinalnoj endoskopiji i testiranju na H. pylori antigen u stolici. Analizirani su demografski podaci,
 simptomi, endoskopski i hematološki nalazi.
 Rezultati: H. pylori infekcija je potvrđena kod 63,25% pacijenata, bez značajne razlike između polova. Zabeležen je trend porasta prevalencije sa
 godinama, ali bez statističke značajnosti (p=0,060). Epigastrični bol (p=0,0068) i gorušica (p<0,0001) su bili značajno češći kod H. pylori pozitivnih
 pacijenata, dok su hronični gastritis (p=0,005) i duodenalni ulkus (p=0,029) bili dominantni endoskopski nalazi kod ove grupe. Značajno veći procenat
 H. pylori pozitivnih pacijenata imao je snižene vrednosti broja eritrocita i hemoglobina u odnosu na negativnu grupu (p<0,01). Prosečan hematokrit
 bio je niži u H. pylori pozitivnoj grupi (p=0,013), ali se nije značajno razlikovao od referentnih vrednosti.
 Zaključak: H. pylori infekcija je česta među pacijentima sa dispepsijom i povezana sa specifičnim simptomima, patološkim endoskopskim nalazima i
 hematološkim promenama. Testiranje na H. pylori je ključno u proceni dispepsije, dok H. pylori negativni pacijenti sa upornim simptomima zahtevaju
 dodatnu dijagnostiku.

 Uvod: Kognitivni pojačivači (KP) poboljšavaju kognitivne funkcije putem neurotransmitera CNS-a. Čine raznorodnu grupu supstanci koje se
 svakodnevno uzimaju kao napici nalik kafi, biljni lekovi i dijetetski suplementi (“meki pojačivači”) ili lekovi koji se koriste u lečenju bolesti
 (nootropici). Upotreba i zloupotreba su česte u studentskoj populaciji sa brojnim etičkim pitanjima.  
Cilj: Utvrđivanje informisanosti studenata medicine, njihovih stavova o upotrebi i stepenu rizika od neželjenog delovanja KP, na osnovu pretpostavke
 da je upotreba ovih supstanci redovna.
 Materijal I metode: Studija preseka je sprovedena po tipu anonimnog anketnog istraživanja na Medicinskom fakultetu Priština sa privremenim
 sedištem u Kosovskoj Mitrovici. U ispitivanju su dobrovoljno učestvovali studenti medicine prve tri godine integrisanih studija koji nisu položili ispit iz
 predmeta Farmakologija sa toksikologijom. Upitnik je obuhvatio socio-demografske podatke, podatke o koncentraciji i navikama u učenju, stepen
 informisanosti, procenu upotrebe i procenu rizika korišćenja KP. Stratifikacija uzorka je izvršena prema polu studenata, a Likert-ova skala je poslužila
 za rangiranje stavova ispitanika.
 Rezultati: Od ukupnog broja anketiranih (n=249) u konačnu statističku analizu podataka uključeno je 169 anketnih upitnika (M 32,5 %, Ž 67,5%).
 Najviše studenata je bilo sa druge godine studija (40%), dok je najviše studentkinja bilo sa prve godine (48,2%). Uočena je statistički značajna razlika
 između ispitivanih grupa u odnosu na godinu studiranja (p=0,009).  Informacije o KP su novina za 40,2% ispitanika (M 49,1%, Ž 36%). Da je o njihovoj
 primeni dovoljno informisano smatra 23,7 % ispitanika (M 20%, Ž 25,4%). Postoji statistički značajna razlika u upotrebi internet baza za informisanje o
 KP (p<0,001).Najveći broj studenata (71,6%) koristi internet za informisanje o KP, pri čemu je korišćenje internet baza bilo statistički značajno veće
 kod žena u odnosu na muškarce (M 56,4 %,Ž 78,9 %; p=0,002). Više od polovine ispitanika (50,3%) koristi Mediately bazu kao pouzdanu bazu podataka o
 lekovima. Od ukupnog broja studenata 40,8% upotrebljava neki od navedenih KP (M 43,6%, Ž 39,5%). Najčešći razlozi za upotrebu kod obe grupe
 ispitanika su poboljšanje koncentracije (M 27,3%, Ž 28,9%) i uspešnije polaganje ispita (M 25,5%, Ž 15,8%). Oba pola najviše koriste ginko bilobu (M
 29,1%, Ž 32,5%) i metilksantine (M 29,1%, Ž 17,5%). Studenti znatno češće upotrebljavaju kreatin u odnosu na studentkinje (M 20%; Ž 2,6%; p=0,003).
 Obe grupe studenata su prema medijani i interkvartilnom opsegu (25-75%) uočenog rizika od neželjenih reakcija rangirale kokain (M 9,0; Ž 9,0),
 metamfetamin (M 8,0; Ž 8,0) i amfetamin (M 8,0; Ž 7,0) kao najopasnije, dok je ginko biloba procenjena kao najbezbedniji KP (M 3,0; Ž 3,0). 
Zaključak: Većina studenata nije dovoljno informisana o kognitivnim pojačivačima, iako ih koriste samoinicijativno, radi postizanja boljih rezultata na
 studijama. Neophodno je studente uputiti na adekvatne izvore informisanja i organizovati vannastavne tribine i predavanja o bezbednosti i efikasnosti
 KP pre upotrebe. U skladu sa trendovima u svetu, može se očekivati porast zloupotrebe nootropika na univerzitetima i u našoj zemlji. Smatramo da bi
 trebalo ponoviti ili organizovati slično ispitivanje kroz par godina, po mogućstvu u većem obimu.

Aortic dissection (AD) and pulmonary embolism (PE) are both serious and life-threatening conditions that rarely occur concomitantly. We report a case of a male patient with chronic aortic dissection, pulmonary embolism and decompensated cardiomyopathy with focus on the usage of computed tomography (CT) to ensure timely diagnosis and improve patient management. Case report: Aortic dissection (AD) and pulmonary embolism (PE) are both serious and life-threatening conditions that rarely occur concomitantly. We report a case of a 55-year-old man who was admitted to Coronary care unit due to pulmonary embolism and aortic dissection of abdominal aorta. Conclusion: This case highlights the importance of correct aortic dissection diagnosis and management, as well as the rare but possible association between aortic dissection and pulmonary embolism.

INTRODUCTION: The corona virus desease has led to numerous changes in all aspects of our lives. The educational system through numerous innovative learning methods managed the smooth conduct of distance learning. OBJECTIVE: The aim of our study is to examine the attitudes of medical and dental students about quality and effectiveness of online versus traditional teaching, in the course of Hystology and Embriology during the duration of the COVID-19 pandemic. METHODS: The research was conducted online, with the help of a questionnaire designed on the Google Forms platform. The cross-sectional study included second-year students of medicine and dentistry at the Faculty of Medicine in Priština -Kosovska Mitrovica, who during the 2020/21 academic year followed online and classical classes in the subject Histology and Embryology. The results were processed using descriptive statistical methods and appropriate tests for testing the hypothesis about the significance of the difference between two, three or more samples. RESULTS: Out of the total number of surveyed students (n=60), 95% of students attended traditional classes, 88.3% of students attended classes via Zoom platform, while 85% of respondents used Moodle platform. The highest percentage of very satisfied (38.3%) and satisfied (51.6%) students was with traditional teaching. The percentage of available lecturers during online classes is 73.3%, and 76.7% during tradicional teaching. 75% of students believe that tradicional teaching can not be replaced by online teaching method. 68% of students used the literature and available presentations on the Moodle platform to prepare for the exam. A significant correlation was found in the case of satisfaction with the grade and the achieved success in the exam (p=0,001). CONCLUSION: The results of our research show that students preferred traditional over online teaching, which makes traditional teaching a primary and irreplaceable form of education.

INTRODUCTION: The ratio of neutrophils-lymphocytes (NLR) and platelet-lymphocytes (PLR) is a new parameter in the assessment of patients with Hashimoto's thyroiditis OBJECTIVE: The aim of this study was to investigate the effect of NLR and PLR in patients with Hashimoto's thyroiditis MATERIALS AND METHODS: In this cross-sectional study, subjects were subjected to tests of thyroid gland function, antithyroid antibodies, as well as laboratory analyzes of blood count with determination of NLR and PLR. The respondents were grouped into two groups. The first group was patients with Hashimoto's thyroiditis (HT), while the second group consisted of healthy individuals who represented the control group. RESULTS: NLR was statistically significantly higher in patients with HT compared to the control group (2.62±0.8 and 2.43±0.8, respectively; p=0.02), while PLR was higher in people with HT compared to the control group, but without statistical significance significance (169±42.5; 159±40.3; p=0.08). Among the examined patients with HT, the group with hypothyroidism showed statistically higher NLR values compared to the group of patients with euthyroid status (2.7±0.9 ; 2.31±0.7 p=0.03). Among the examined patients with HT, the group with hypothyroidism showed statistically higher PLR values compared to the group of patients with euthyroid status, as well as the group with subclinical hypothyroidism (177.8±48.2; 148.3±39.3; 155.5±42.5 p=0.04). NLR and PLR show a statistically significant positive correlation with the level of TSH, Anti TPO and TG At in the group with HT. CONCLUSION: NLR and PLR can serve as practical and valuable markers of the clinical course of the disease, but also markers of autoimmune diseases that progress with chronic inflammation.

Obesity is one of the most common chronic, non-infectious diseases in the world and our country, and it is characterized by excessive accumulation of fat tissue in the body and an increase in body weight. The increase in the number of obese people is an important global health problem. Obesity is associated with cardiometabolic and psychosocial comorbidities, and may also affect years of healthy life and reduce life expectancy. Numerous factors, such as biological predisposition, socioeconomic factors and environmental factors, interact and influence the development and maintenance of obesity. Excess adipose tissue in the body and its dysfunction is associated with inflammation and increased risk of metabolic, mechanical and mental complications. It is very important to monitor the incidence of obesity and its impact on the development of chronic non-communicable diseases and life expectancy due to the development and implementation of strategies to prevent the increase in the number of obese people.

Cor triatriatum is a rare condition. It comprises around 0.1% to 0.4% of all congenital heart malformations. There are two types of this anomaly: cor triatriatum sinister (CTS), which is more common and accounts for 92% of all cases, and cor triatriatum dexter (CTD). This condition usually presents at an early age and is diagnosed mainly during early childhood. In some patients, who have less severe cases of CTS, diagnosis could be made in adulthood. We report an unusual case of a 78-year-old woman who was diagnosed with CTS for the first time. The patient was admitted to the cardiology department with symptoms of chest pain and dyspnoea. Physical examination revealed diffusely diminished breath sounds, with focal wheezing, and irregular heart rate, with no murmurs, while blood pressure was 140/90 mmHg. A transthoracic echocardiogram revealed an accessory membrane in the left atria suggestive of CTS.
