Pulmonary hypertension (PH) is a hemodynamic condition characterized by a mean pulmonary artery pressure (mPAP) ≥ 25 mmHg at rest, pulmonary arterial wedge pressure (PAWP) ≤ 15 mmHg, and pulmonary vascular resistance (PVR) > 240 dyn·s·cm⁻⁵. The annual incidence of pulmonary arterial hypertension (PAH) is approximately 3–10 new cases per million adults. It is estimated that the prevalence of pulmonary hypertension in individuals over 65 years of age is around 10%.The aim of this study is to present the case of a female patient with progressive dyspnea in whom PAH remained undiagnosed for a prolonged period.A 74-year-old female patient, M.P., was hospitalized in the Coronary Care Unit of the Clinical Center in Kosovska Mitrovica due to symptoms of shortness of breath, choking, fatigue, leg swelling, and weakness. The admission ECG revealed: sinus rhythm, normal axis, high R wave in V2, ST depression, and negative T waves in leads II, III, aVF, and V4–V5. Echocardiography findings showed right ventricular enlargement (2.9 cm), pulmonary artery dilation (3.3 cm), 1–2+ pulmonary regurgitation, and 3+ tricuspid regurgitation, with a systolic pulmonary artery pressure (SPAP) of up to 126 mmHg. The right ventricle measured 5.3 cm in the 4Ch view, with a TAPSE of 1.8 cm. Right heart catheterization revealed the following pressures: PA 78/34/57 mmHg, RV 74/8/10 mmHg, RA 6/6/7 mmHg, CO 4.3 l/min, and LV 99/10/8 mmHg. Although primary pulmonary hypertension is predominantly a disease of younger individuals, it should also be considered in older patients presenting with progressive dyspnea in the absence of structural heart disease.

Introduction/Objective 
The objective of this study was to determine the prevalence of alcohol use in the student population of the University of
Belgrade.
Methods 
The cross-sectional study was conducted in a population of 2,000 students of the Belgrade University. Four faculties (Medicine, Geography,
Economics, Electrical Engineering) from which the students participating in this research were chosen by the method of random choice (by computer
listing), conducted in the period April - June 2010.
Results 
Among our respondents, the highest amount of spirits is consumed by respondents from the Faculty of Electrical Engineering, with 22% of
them consuming more than 6 shots on each occasion, while the smallest number of students who drink more than 6 shots on each occasion are from
the Faculty of Economics, with 8%. Students from the Faculty of Electrical Engineering, who have the lowest prevalence of cigarette use, consume
alcohol in a binge drinking pattern. The highest frequency of binge drinking in the past year and in the past month before the survey was among
respondents from the Faculty of Geography.
Conclusion 
There is a need for developing a conscience about all the effects that alcohol has, especially physical ones which are not usually noticed
immediately; taking responsibility for own actions; working on a healthy life style and educating people to enhance and improve their health control.

Thyroid hormones, thyroxine and triiodothyronine, affect the work of all organs and organ systems. Whether they are in excess or in deficit, they lead to significant disturbances in the homeostasis of the organism, changing first of all the metabolic processes and leading to significant clinical manifestations, primarily in the cardiovascular, but also in other organ systems. The imbalance of thyroid hormones also has oralmanifestations, which are often the reason why patients visit the dentist. However, what worries dentists the most is the possibility of acute decompensation of hyper or hypothyroidism, with the appearance of thyrotoxic storm or myxedema coma, which are life-threatening conditions. Therefore, a valid pre-procedural evaluation and preparation of patients with thyroid hormone function disorders for pre-planned dental interventions is of great importance. During dental procedures, it is necessary to adhere to recommendations regarding the choice of local anesthetics, hemostasis, drug interactions, the possibility of infection and minimizing stress, all in order to avoid acute decompensation of thyroid imbalance.

Background: People with diabetes more often experienced severe clinical forms of COVID-19. However, it has been hypothesized that certain antidiabetic drugs may be associated with better outcomes in COVID-19 patients. The aim of this study was to analyze whether the COVID-19 pandemic influenced the change in consumption of antidiabetic drugs in Serbia.

Methods: This descriptive analysis was carried out using publicly accessible data obtained from the official website of the Medicines and Medical Devices Agency of Serbia during the period 2006-2022. The joinpoint regression analysis was applied to investigate the dynamics of antidiabetic drugs utilization over time.

Results: In the Republic of Serbia, this study analyzed the use of 28 antidiabetic drugs between 2006 and 2022.The results showed that at the beginning of the COVID-19 pandemic, there was an increase in consumption of dulaglutide (starting from 2020) and a decrease in consumption of insulin detemir (starting from 2019), insulin lispro (combined) and insulin lispro (fast-acting) (starting from 2020).

Conclusion: Our study revealed significant changes in the usage of certain antidiabetic drugs, such as increased consumption of dulaglutide and decreased use of various insulin types. These changes reflect the evolving strategies in diabetes treatment to better support patients during this global health crisis.

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.
 Ključne reči: kognitivni pojačivači, informisanost studenata, stavovi studenata

 Ruptura potkožne tetive ekstenzora policis longusa (EPL) je jedna od najčešćih povreda tetiva ekstenzora šake. Ova vrsta povrede može biti posledica
 trauma ručnog zgloba. Češće se javlja kao posledica degenerativne ili inflamatorne bolesti. Ponekad se to dešava bez predisponirajućeg stanja, zbog
 kontinuiranih pokreta savijanja i opružanja palca šake.
 Ruptura tetive EPL-a se obično dešava u predelu Listerove kvrge gde su trenja najveća. Kontinuirano ponavljanje mikrotrauma može da uzrokuje
 rupturu. Engkvist i Lundborg [1] su postavili hipotezu o patogenezi mehanizama ove povrede.  Smatrali su da nakon trauma ili zapaljenja formiran
 hematom unutar omotača tetive dovodi do povećanja pritiska u neelastičnom prostoru. Povećanje pritiska može izazvati promene u snabdevanju krvi i
 može dovesti do nekroze i rupture struktura tetiva. Nakon prekida kontinuiteta tetive EPL-a, retrakcija proksimalnog okrajka je praćena
 degenerativnim procesima koji ugrožavaju direktnu suturu.
 Predloženi su mnogi tretmani, artrodeza interfalangealnog (IP) zgloba palca ili transpozicija tetive ekstenzor indicis proprius (EIP) koju je razvio
 Mensch 1925. god. [1].
 Transpozicija tetive šake je hirurška procedura која uključuje repozicioniranje funkcionalne tetive како bi se obnovila funkcija oštećene tetive šake.
 Ova operacija ima za cilj da vrati pokret, funkciju i snagu šake.
 U ovom radu prenosimo naše iskustvo u lečenja traumatske rupture tetive EPL-a metodom transpozicije tetive EIP-a. Opisujemo operativnu tehniku
 transfera tetive EIP-a na tetivu EPL.

This article focuses on the sonographic axamination techique for evaluation of intracranial translucencies during the first trimester ultrasound scan. Appropriate knowledge of sonographic landmarks is the most important factor for evaluation normal as well as abnormal brain structure, and this examination may enable detection of open spina bifida and Arnold – Chiari anomaly at an early stage of fetal develpoment.

Introduction:

Diabetes insipidus (DI) is a disease that occurs due to inappropriate secretion of anti-diuretic hormone from the pituitary, or as a result of disorder in which the level of the kidneys cannot adequately respond to the secretion of this hormone. Also, it is known as central diabetes insipidus. The most common causes are head traumas, tumors of the hypothalamus and pituitary glands, inflammatory processes, histiocytosis, anomalies in the development of brain. It can appear in the form of familial diabetes insipidus or in certain syndromes (Wolfram syndrome). It is characterized by hypotonic polyuria higher than 3l/24h (which persists if even taking liquids stops), then by nocturia and compensatory polydipsia. Enuresis often occurs among children.

Case report:

A boy, aged 11, lives with his mother and brothers. Mother noticed that the boy was urinating frequently in last few months (diuresis 4.6 l/24h, and 3.25 l/24h). After two months, the boy developed double images and severe headaches, vomiting, inability to see, squinting in the right eye and headache in the back of the head. MNR of the endocranium indicates the presence of a tumor formation. The tumor was surgically removed, and the boy started with chemotherapy and radiotherapy. Due to persistent diabetes insipidus, the boy started using desmopressin-acetate - in tablet form. Active substance desmopressin - acts in the same way as the natural hormone vasopressin and regulates the kidney's ability to concentrate urine. The positive effect of taking the drug appeared after three weeks from the start of taking the therapy.

Conclusion:

Central (neurogenic) DI occurs as a result of a relative or absolute deficiency of antidiuretic hormone, which is responsible for the osmolality of body fluids. Based on this case, we want to show the importance of early diagnosis of the disease in order to improve the prognosis and the necessity of careful monitoring of these patients.

The discovery that sunlight can cure rickets was first scientifically confirmed in 1919. Shortly thereafter, in 1924, it was found that inactive lipids in the diet and skin are converted into antirachitic substances under the influence of UV light. Vitamin D (Vit D), also known as the "sunshine vitamin,"
was first identified in 1931. In recent decades, it has regained the focus of interest among the broader scientific community and dermatologists.
Specifically, certain dermatoses have been associated with low Vit D levels, leading to its supplementation in patients. On the other hand, some
dermatoses worsen with sun exposure, necessitating strict avoidance of sunlight and the therapeutic use of Vit D preparations.We are witnessing a
growing number of cases of melanoma and non-melanoma skin cancers, with excessive sun exposure being the primary etiological factor in most
cases. This paper provides a literature review on the historical discovery of Vit D and presents findings from studies examining Vit D levels not only in
various dermatoses but also in other diseases. The number of studies, as well as the spectrum of diseases in which the role of Vit D is being
investigated, continues to increase.
