UVOD: Atrofični ožiljci nastaju kao česta posledica nelečenih akni, usled smanjene sinteze kolagena i poremećenih mehanizama reparacije tkiva. Plazma bogata trombocitima (PRP) se poslednjih godina sve češće koristi u terapiji ožiljaka zahvaljujući svojim regenerativnim sposobnostima, kao što su stimulacija sinteze kolagena, angiogeneza i remodelovanje tkiva.

PRIKAZ BOLESNIKA: Prikazan je slučaj pacijentkinje starosti 33 godine sa atrofičnim ožiljcima od akni tipa icepick i boxcar, lokalizovanim obostrano na obrazima. Sprovedena su tri PRP tretmana u razmaku od 4-6 nedelja. Korišćen je komercijalni PRP set, a dobijena plazma aplikovana je intradermalno iglom do 30G na dubini od oko 2mm. Sprovedena je klinička evaluacija i fotodokumentacija pre i posle serije tretmana. Nakon sprovedene terapije zabeleženo je značajno kliničko poboljšanje.

ZAKLJUČAK: PRP terapija se pokazala kao efikasna, bezbedna i dobro podnošljiva terapija u lečenju atrofičnih ožiljaka od akni. Iako standardizovan protokol u lečenju atrofičnih ožiljaka ne postoji, ovaj prikaz slučaja podržava PRP kao vrednu samostalnu ili kombinovanu terapijsku proceduru.

KLJUČNE REČI: Plazma bogata trombocitima, atrofični ožiljci od akni

Introduction: Mental illness is the most common cause of disability and a major public health issue worldwide due to its increasing prevalence, the difficulty of therapeutic treatment and the possible progression of the disease.

Objectives: To determine the prevalence of depressive symptoms in the student population over a 5-year period and the connection between sociodemographic characteristics and lifestyle habits of students and the occurrence of depressive symptoms.

Methods: A retrospective study was conducted in the period 2018-2022 at the Institute for Health Protection of Students in Belgrade. Data was obtained by analyzing the questionnaire completed by student including the PHQ-9 questionnaire. The difference between students' socio-demographic characteristics and lifestyle habits and the presence of depression was examined using the X2 test. Variables that were significant in the X2 test were included in a binary logistic regression. The data were analyzed with SPSS 20.

Results: 34047 students participated, 17.53% of whom were identified as individuals with high risk for depression. In the study first graders showed more symptoms of depression than third graders. The students who showed symptoms of depression were typically female, lived with their parents, did not consume alcohol or smoke and exercised 2-3 times per week. In the logistical regression model, alcohol consumption was positively and significantly associated with the presence of depressive symptoms.

Conclusion: The preventive measures should focus on lower alcohol consumption and frequent physical activity. Regular systematic examinations and referral to a specialist for the individuals identified as high-risk for depression should be mandatory.

Arterial hypertension is well-known strong risk factor that can lead to the development of coronary artery disease, heart attacks, heart failure, stroke, and other heart-related issues. Arterial hypertension has increased exponentially in the last few decades in adult men and women. Traditionally arterial hypertension is classified as primary, when no specific cause has been identified and is usually associated with multiple genetic polymorphisms and various environmental factor interactions, and secondary when there are conditions with biological plausibility to cause hypertension. Traditional data in medical textbooks indicate that in 90-95% of cases, arterial hypertension is primary, while only a small percentage of cases have secondary hypertension. European guidelines for elevated blood pressure and hypertension from 2024 indicate a higher prevalence of secondary hypertension, ranging from 10-35% of cases. Secondary hypertension is still not fully understood and often remains undiagnosed. Identifying the underlying cause of secondary hypertension is crucial, as treating the root condition can significantly reduce the risk of heart disease, stroke, and improve overall quality of life. Obesity is a major global health problem and the prevalence of obesity is constantly increasing and simultaneously leads to an increase in the prevalence of both primary and secondary arterial hypertension. Some forms of secondary hypertension cause more severe cardiac damage than primary hypertension and are associated with a higher cardiovascular risk. Secondary hypertension is more often resistant hypertension, which means that it is difficult to achieve target blood pressure values. It is important to timely conduct appropriate examinations and begin treatment promptly.

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.

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.

 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

Sveži prelomi u ortopedskoj hirurgiji i traumatologiji, dovode do hemodinamske nestabilnosti celokupnog organizma. Kod otvorenih preloma, stepen
 hemodinamske nestabilnosti organizma je značajno veći. Prioritet u lečenju svežih preloma ima DAMAGE CONTROL IN ORTHOPEDIC (DCO). DCO je
 invazivna procedura koja ima ulogu kako u stabilizaciji preloma, tako i u kontroli krvarenja. Prelomi dugih kostiju kao i prelom karlice su apsolutna
 indikacija za DCO. Slobodno možemo reći da ova procedura prestavlja prioritet u lečenju svežih preloma. Procedura je individualizovana u zavisnosti
 od težine povrede kao i  hemodinamskog statusa povređenog pacijenta. U ortopedskoj hirurgiji i traumatologiji kao standardna procedura u DCO
 koristi se spoljašnji fiksator po Mitkoviću. Ortopedski hirurzi moraju biti jako prisebni i obazrivi kod pregledapacijenata sa politraumom i da
 prepoznaju tkzv. trougao smrti. Trougao smrti čine: acidoza, hipotermija i koagulopatija. Svaka karika je medjusobno povezana jedna sa drugom
 dovode do ireverzibilnih promena u organizmu što za posledicu ima smrtni ishod. DCO se sprovodi u tri faze: 1) podrazumeva kontrolu kvarenja,
 smanjenje kontaminacija bakterijama, kao i privremenu fiksaciju preloma. Sve ovo je neophodno uraditi u roku od 1-2h.; 2)  obuhvata stabilizaciju
 vitalnih parametara u JIN-e kao i reanimacija pacijenta ordiniranjem neophodne terapije, krvi i krvnih derivata.; 3) podrazumeva definitivna metoda
 lečenja u smislu nastavka lečenja preloma spoljasnjim fiksatorom ili konverzija u neku drugu metodu lečenja.

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.

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.
