Sport participation is considered as a factor of potential influence on illicit drug misuse (IDM) in adolescence, but there is an evident lack of studies which prospectively investigated this problem. This study aimed to prospectively investigate the sports-related factors related to IDM and the initiation of IDM among older adolescents. The participants were 436 adolescents (202 females; 16 years old at study baseline). They were tested at baseline and follow-up (two years later). The predictors included variables associated with different facets of sports participation and success in sports. The criteria were (i) baseline IDM, (ii) follow-up IDM, and (iii) initiation of IDM between baseline and follow-up. Crude and adjusted (controlled for parental conflict, age, socioeconomic status, and gender) logistic regressions were applied to establish correlations between predictors and criteria. There were higher odds for baseline IDM in adolescents who quit individual sports (OR: 4.2, 95% CI: 1.3-13.9), who had better competitive sports achievements (OR: 1.8, 95% CI: 1.0-3.3), and those involved in sports for a longer time (OR: 1.6, 95% CI: 1.0-2.5). The IDM at follow-up was more prevalent in adolescents who were involved in sports for a longer time (OR: 1.7, 95% CI: 1.1-2.6). Initiation of drug use was predicted by longer experience in sports (OR: 1.8, 95% CI: 1.1-3.1). Sports-related factors were more negatively than positively related to illicit drug use. Most probably, the transition from junior to senior level in sports put specific stress on those adolescents who were highly committed to sports until that time, but who then had to question their own sports abilities and future potential in sports. Sport-authorities should be informed on established results and specific public-health efforts aimed at preventing IDM in athletic adolescents are urgently needed.

Background: This study aimed to prospectively investigate the scholastic factors related to illicit drug misuse (IDM) and the initiation of IDM among older adolescents from Bosnia and Herzegovina. Methods: This 2-year prospective study included 436 participants (202 females), who were an average of 16 years old at the beginning of the study (baseline). The participants were tested at baseline and follow-up (20 months later). The predictors included variables of scholastic-achievement (grade point average, school absences, unexcused absences and behavioral grade). The criteria were: (i) IDM at baseline; (ii) IDM at follow-up; and (iii) initiation of IDM over the study course. Results: Logistic regression indicated increased odds of IDM in adolescents who were more frequent absent from school (baseline: Odds Ratio (OR): 3.73, 95% Confidence Interval (CI): 2.12–6.57; follow-up: OR: 2.91, 95% CI: 1.90–4.65). The lower grade point average and more unexcused absences were evidenced for adolescents who consumed drugs on follow-up (OR: 1.67, 95% CI: 1.11–2.51; OR: 1.74, 95% CI: 1.30–2.32 for grade point average and unexcused absences, respectively). Initiation of IDM was predicted by frequent absences from school (OR: 2.2, 95% CI: 1.3–3.8), and lower behavioral grades (OR: 1.9, 95% CI: 1.2–3.3). Conclusions: The findings confirmed strong correlations between scholastic failure and IDM. Absences from school and lower behavioral grades at baseline were predictive of the initiation of IDM in older adolescents.

The study reports a case of primary hyperparathyroidism in a middle-aged patient who was first admitted for persistent ankle pain and local swelling. The subsequent clinical procedures suggested cystic changes in several leg bones, which were later shown to be caused by the parathyroid adenoma. Clinical presentation of the primary hyperparathyroidism can be highly misleading, sometimes causing various clinical procedures before it is certainly diagnosed.

UVOD: Primjena umjetnih zglobova - endoproteza svakodnevni je ortopedski zahvat. Prema literaturi, oko 30% svih operacijskih zahvata u ortopediji u svijetu pripada ugradnji endoproteza velikih zglobova. Sustavno pracenje bolesnika s endoprotezom putem registara u svijetu je postalo uobicajena praksa sredinom 1990-ih godina, i smatra se najucinkovitijom metodom pri ocjeni koje endoproteze i operacijske tehnike primijeniti za određenu populaciju. CILJ: Ispitati kolika je ucestalost ugradnje endoproteza u Republici Hrvatskoj tijekom 2005. godine (kuk, koljeno, rame i drugi zglobovi). MATERIJALI I METODE: Istraživanje ucestalosti ugradnje endoproteza u Hrvatskoj znanstveni je projekt pri Ministarstvu znanosti, obrazovanja i sporta RH. U projekt su pozvane sve zdravstvene ustanove u Hrvatskoj s ortopedskom djelatnoscu, a koje ugrađuju endoproteze. REZULTATI: U petnaest zdravstvenih ustanova, koliko ih se ukljucilo u Registar, ucinjeno je ukupno 15, 838 operacijskih zahvata, od cega je 4, 156 operacija ugradnja endoproteza. Analizirajuci pojedinacno prema zglobovima, ugrađeno je 3, 080 endoproteza kuka (74% od svih endoproteza), 1, 064 endoproteza koljena (26%), te 12 endoproteza ramena (<1%). ZAKLJUCAK: Operacije ugradnje endoproteza svih zglobova predstavljaju oko 26% svih ortopedskih zahvata u Hrvatskoj. Taj broj ipak varira između ustanova (od 7 do 49%). Ipak, brojem od 0, 92 ugrađene endoproteze na 1000 stanovnika godisnje Hrvatska pripada u razinu zemalja zapadnoga svijeta. Cilj rada Hrvatskog registra endoproteza jest oblikovati smjernice i postupnike s ciljem unaprijeđenja endoprotetike i konacno poboljsanja medicinsko-ekonomskih ishoda primjene endoproteza.
