Thyroid carcinomas in children and adolescents are rare tumors and the most common among them is papillary thyroid cancer (PTC). Its etiology is still under research and has not been clearly defined thus far, especially in young individuals. The aim of this case-control study was to determine potential risk factors for the development of PTC in children and adolescents. This type of study has not been carried out previously in this age group. A case-control study was carried out during a 15-year period, between 1995 and 2009. The case group included 75 patients with PTC younger than 20 years of age, with the youngest patient being 6.5 years old; 45 patients were female and 30 were male. The control group included the same number of participants, and the cases were individually matched by sex, age, and place of residence. Conditional univariate and multivariate logistic regression methods were applied in data analysis. According to univariate logistic regression analysis, PTC in children and adolescents was significantly related to the following factors: family history of thyroid cancer, family history of residence in an endemic-goiter area, family history of benign thyroid disease, and family history of nonthyroid malignant tumors. According to the multivariate logistic regression method, PTC in children and adolescents was independently related to a family history of thyroid cancer (odds ratio=4.5, 95% confidence interval=1.2-19.8) and a family history of nonthyroid malignant tumors (odds ratio=3.8, 95% confidence interval=1.4-8.7). In conclusion, all of the factors associated with the development of PTC in children and adolescents were related to their family history. © 2013 Wolters Kluwer Health Lippincott Williams & Wilkins.

Anaplastic thyroid cancer (ATC) is one of the tumors with the shortest survival in human medicine. Aim. The aim was to determine the importance of age in survival of patients with ATC. Material and Methods. We analyzed the data on 150 patients diagnosed with ATC in the period from 1995 to 2006. The Kaplan-Meier method and log-rank test were used to determine overall survival. Prognostic factors were identified by univariate and multivariate Cox regression analysis. Results. The youngest patient was 35 years old and the oldest was 89 years old. According to univariate regression analysis, age was significantly associated with longer survival in patients with ATC. In multivariate regression analysis, patients age, presence of longstanding goiter, whether surgical treatment is carried out or not, type of surgery, tumor multicentricity, presence of distant metastases, histologically proven preexistent papillary carcinoma, radioiodine therapy, and postoperative radiotherapy were included. According to multivariate analysis, besides surgery (P = 0.000, OR = 0.43, 95% CI = 0.29-0.63), only patients age (P = 0.023, OR = 0.68, 95% CI = 0.49-0.95) was independent prognostic factor of favorable survival in patients with ATC. Conclusion. Age is a factor that was independently associated with survival time in ATC. Anaplastic thyroid cancer has the best prognosis in patients younger than 50 years. © 2014 Vladan Zivaljevic et al.

OBJECTIVE - To investigate if there is a reduced risk of type 1 diabetes in children breastfed or exclusively breastfed by performing a pooled analysis with adjustment for recognized confounders. RESEARCH DESIGN AND METHODS - Relevant studies were identified from literature searches using MEDLINE, Web of Science, and EMBASE. Authors of relevant studies were asked to provide individual participant data or conduct prespecified analyses. Meta-analysis techniques were used to combine odds ratios (ORs) and investigate heterogeneity between studies. RESULTS - Data were available from 43 studies including 9,874 patients with type 1 diabetes. Overall, there was a reduction in the risk of diabetes after exclusive breast-feeding for >2 weeks (20 studies; OR = 0.75, 95% CI 0.64- 0.88), the association after exclusive breast-feeding for >3 months was weaker (30 studies;OR = 0.87, 95%CI 0.75 -1.00), and no association was observed after (nonexclusive) breast-feeding for >2 weeks (28 studies; OR = 0.93, 95% CI 0.81-1.07) or >3 months (29 studies; OR = 0.88, 95% CI 0.78-1.00). These associations were all subject to marked heterogeneity (I 2 = 58, 76, 54, and 68%, respectively). In studies with lower risk of bias, the reduced risk after exclusive breast-feeding for >2 weeks remained (12 studies; OR = 0.86, 95% CI 0.75-0.99), and heterogeneity was reduced (I 2 = 0%). Adjustments for potential confounders altered these estimates very little. CONCLUSIONS - The pooled analysis suggests weak protective associations between exclusive breast-feeding and type 1 diabetes risk. However, these findings are difficult to interpret because of the marked variation in effect and possible biases (particularly recall bias) inherent in the included studies. © 2012 by the American Diabetes Association.

To provide estimates of cardiovascular disease burden to guide future health strategies and interventions and enable improvements in health and performance of the health care system to be monitored. A descriptive study. The study was performed in Serbia without Kosovo and Metohia for the year 2000. Disability-adjusted life years (DALY) was used to provide a comprehensive assessment of premature mortality (years of life lost; YLL) and disability attributable (years lived with disability; YLD) to ischaemic heart disease (IHD) and cerebrovascular diseases, and to estimate the attributable and avoidable burden of these diseases caused by smoking, hypertension, overweight/obesity, physical inactivity, alcohol consumption and an inadequate consumption of fruit and vegetables. IHD was responsible for 150 889 DALY (16.28/1000 population), and cerebrovascular diseases were responsible for 136 090 DALY (14.49/1000 population). There were considerably more YLL for both IHD and stroke than YLD. For both diseases DALY rates increased with ageing in men and women. The risk factors most responsible for IHD and stroke burden were smoking, physical inactivity, hypertension and overweight/obesity. Sex and age differences were present in the burden attributable to various risk factors. Despite limitations the DALY estimates represent a useful measure of the size of the health problem. The DALY and related estimates for cardiovascular disease can be used as a guide for the prevention of IHD and stroke as well as the evaluation of future health gains by reducing population exposure to lifestyle and related risk factors. © 2006, European Society of Cardiology.

The aim of the study was to examine the factors which play a role in the occurrence of differentiated thyroid cancer as related to anaplastic thyroid cancer (ATC). A case-control study was performed during the period 1993 to 2005. The case group comprised of 126 patients with ATC. The control group comprised of 126 patients with papillary thyroid cancer. Cases were individually matched by gender and place of residence. ATC was significantly related to older age (odds ratio = 1.11, 95% confidence interval = 1.07-1.14) and goiter (odds ratio = 1.20, 95% confidence interval = 1.07-1.35).

Introduction: Almost half of patients with non-small-cell lung cancer (NSCLC) are diagnosed at an advanced stage. Our aim was to assess the effects of adding necitumumab to chemotherapy in patients with stage IV NSCLC. Material and methods: A comprehensive literature search was performed according to pre-specified inclusion and exclusion criteria. Data on overall survival, progression-free survival, objective response rate and adverse events were extracted. A meta-analysis was performed to obtain pooled hazard ratios (HR) and corresponding 95% confidence intervals (CI) for time-to-event data and pooled odds ratio (OR) with 95% CI for dichotomous outcomes. Results: The meta-analysis included four randomized clinical trials with 2074 patients. The pooled results showed significant improvement for overall survival (HR = 0.87 (95% CI 0.79–0.95), p = 0.004) when necitumumab was added to chemotherapy in patients with advanced NSCLC. No statistically significant improvement was noted for progression-free survival and objective response rate (HR = 0.83 (95% CI 0.69–1.01), p = 0.06 and OR = 1.46 (95% CI 0.90–2.38), p = 0.13, respectively). Subgroup analysis showed that in patients with non-squamous NSCLC, there was no benefit in overall survival and objective response rate. Patients with advanced NSCLC who received necitumumab were at the highest odds of developing a skin rash (OR = 14.50 (95% CI 3.16–66.43), p = 0.0006) and hypomagnesaemia (OR = 2.77 (95% CI 2.23–3.45), p < 0.00001), while the OR for any grade ≥3 adverse event was 1.55 (95% CI 1.28–1.87, p < 0.00001). Conclusions: The addition of necitumumab to standard chemotherapy in a first-line setting in patients with stage IV NSCLC results in a statistically significant improvement in overall survival, while the results were not significant for progression-free survival and objective response rate. © The Author(s) 2019.

Background: Energy drink (ED) consumption is a global public health issue, especially among adolescents and young adults, and it has become a common practice among medical students all over the world. The aim of this study was to examine the attitudes and practices of medical students about the consumption of ED. Material and methods: A cross-sectional study was conducted among 458 fourth-year medical students in Belgrade using an anonymous questionnaire. In the data analysis, a Chi-square test was used. Results: About one third (32.3%) of the students consumed ED regularly, significantly more often older students (p < .01), smokers (p < .05), and students who drank coffee (p < .05) and alcohol (p < .01). The majority of students (61.5%) consumed ED while studying or before exams, during parties (27.7%) and without a special occasion (27.0%). Mixing alcohol with ED was reported by 12.8% of the students. Side effects after ED consumption have been noted by 59.5% of students of both genders, and the most common were palpitations (42.6%), insomnia (33.8%), and headache (33.1%). Conclusion: There is a need to raise awareness among medical students about energy drinks because they, as healthcare professionals, will educate people in the future. © 2022 Taylor & Francis Group, LLC.

Fixed drug eruptions (FDE) are commonly reported type of mucocutaneous drug eruption. The aim of this paper is to present a patient with multiple mucocutaneous erythema fixum type lesions caused by oral tadalafil use. A short course of topical corticosteroid therapy resulted in complete resolution of all lesions leaving residual hyperpigmentation of the involved skin sites. Mucosal oral lesions were effectively treated with gingival hyaluronic acid 0.2% gel. Conclusion: when assessing a patient of any age with drug eruptions, a thorough personal history should be obtained, in particular data on regular or recreational use of phospodiesterase type 5 inhibitors. © 2013 by Anais Brasileiros de Dermatologia.

Background. The aim of this study was to analyse the relationship between the clinical manifestations, disease severity based on radiography images, functional activity level, and quality of life in patients with knee osteoarthritis in a rural population living in Serbian enclaves in Kosovo, as well as to determine the correlation between the WOMAC and the EQ-5D questionnaire in this population. Method. The cross-sectional study was conducted at the Internal Medicine Clinic, Clinical Hospital Center Pristina-Gracanica, located in Laplje Selo from February to December 2013. One hundred patients with confirmed (American College of Rheumatology criteria) knee osteoarthritis completed the EQ-5D and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaires, rated pain on a visual analogue scale (VAS), and underwent knee radiographic examinations. Result. Most patients were obese with moderate radiographic changes according to the Kellgeren-Lawrence scale and suffered from very severe pain according to the VAS scale. The duration of disease significantly correlated with the WOMAC scores, VAS score, and all of the scores on the EQ-5D, except for mobility. The age of participants showed a similar correlation with the same variables. The patients with higher Kellgren-Lawrence scores (3-4) were significantly older, with a significantly higher body mass index (BMI) and longer duration of disease than patients with lower scores (1-2). Significantly higher VAS, pain/discomfort EQ-5D, and WOMAC pain and function scores were also recorded among patients with more significant radiological changes. The correlations between WOMAC and EQ-5D were satisfactory. Conclusion. The severity of clinical manifestations and radiographic area changes may affect functional ability and the quality of life in knee OA patients living in rural areas, which requires adequate treatment and physical therapy. © 2019 Gordana Nikolic et al.

Herpes zoster is a common dermatological condition which affects up to 20% of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. Case report: We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving S2-S4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Conclusion: Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash. © 2011 Elsevier Editora Ltda.

Background: The purpose of this study was to investigate which psychosocial risk factors show the strongest association with occurrence ofmyocardial infarction (MI) in the population of Belgrade in peacetime, after the big political changes in Serbia. Methods: A case-control study was conducted involving 154 consecutive newly diagnosed patients with MI, and 308 controls matched by gender, age, and place of residence. Results: According to conditional logistic regression analysis, after adjustment for conventional coronary risk factors, the odds ratios (95% confidence intervals) for work-related stressful events, financial stress, deaths and diseases, and general stress were 3.78 (1.83-7.81), 3.80 (1.96-7.38), 1.69 (1.03-2.78), and 3.54 (2.01-6.22), respectively. Among individual stressful life events, the following were independently related to MI: death of a close familymember, 2.21 (1.01-4.84); death of a close friend, 42.20 (3.70-481.29);major financial problems, 8.94 (1.83-43.63); minor financial problems, 4.74 (2.02-11.14); changes in working hours, 4.99 (1.64-15.22); and changes in working conditions, 30.94 (5.43-176.31). Conclusions: During this political transition period, stress at work, financial stress, and stress in general as they impacted the population of Belgrade, Serbia were strongly associated with occurence ofMI. © 2016, Republic of China Society of Cardiology.

Background: The aim of our study was to investigate the incidence of papillary thyroid microcarcinoma (PTMC) in patients operated for benign thyroid diseases (BTD) and its relation to age, sex, extent of surgery and type of BTD. Methods: Retrospective study of 2466 patients who underwent thyroid surgery for BTD from 2008 to 2013. To determine independent predictors for PTMC we used three separate multivariate logistic regression models (MLR). Results: There were 2128 (86.3%) females and 338 (13.7%) males. PTMC was diagnosed in 345 (16.2%) females and 58 (17.2%) males. Age ranged from 14 to 85 years (mean 54 years). Sex and age were not related to the incidence of PTMC. The overall incidence of PTMC was 16.3%. The highest incidence was in Hashimoto thyroiditis (22.7%, Χ2=10.80, p<0.001); and in patients with total/near-total thyroidectomy (17.7%, Χ2=7.05, p<0.008). The lowest incidence (6.6%, Χ2=9.96, p<0.001) was in a solitary hyperfunctional thyroid nodule (SHTN). According to MLR, Hashimoto thyroiditis (OR 1.54, 95% CI 1.15-2.05, p<0.003) and SHTN (OR 0.43, 95% CI 0.21-0.87, p<0.019) are independent predictors. Since the extent of surgery was an independent predictor (OR 1.45, 95% CI 1.10-1.92, p=0.009) for all BTD, and sex and age were not; when the MLR model was adjusted for them, Graves disease (OR 0.72, 95% CI 0.53-0.99, p<0.041) also proved to be an independent predictor. Conclusions: Sex and age are not statistically related to the incidence of PTMC in BTD. The incidence of PTMC is higher in Hashimoto thyroiditis and patients with total/near-total thyroidectomy; and lower in patients with a SHTN and Graves disease. © 2015 Slijepcevic et al.

Aims and background. Thyroid cancers are relatively rare tumors that appear more frequently in women than in men. Accordingly, most studies focus on studying risk factors for thyroid cancer in women and consequently on various hormonal or reproductive factors that are specific for women. The aim of our study was to examine risk factors for developing well-differentiated thyroid cancer in men. Heretofore, we did not encounter in the literature a study that was solely focused on studying risk factors for well-differentiated thyroid cancer in men. Methods. A case-control study was performed from 2005 to 2010. The case group included 204 consecutive well-differentiated thyroid cancers in male patients (180 papillary and 24 follicular including Hürthle cell). The control group comprised the same number of cases. Patients were individually matched by gender, age and place of residence. Statistical analysis included conditional univariate and multivariate logistic regression methods. Results. According to univariate logistic regression, well-differentiated thyroid cancer in men was significantly related to smoking status, duration of smoking, number of cigarettes smoked per day, history of goiter or thyroid nodules, history of non-thyroid cancer, diabetes mellitus, radiotherapy of the head and neck, and history of malignant tumors. According to multivariate logistic regression, it was independently related to smoking status (OR = 0.36; 95% CI, 0.19-0.69), history of goiter or thyroid nodules (OR = 9.19; 95% CI, 1.25-64.58), and a history of malignant tumors (OR = 2.11; 95% CI, 1.19-7.33). Conclusions. Risk factors for well-differentiated thyroid cancer in men were goiter or thyroid nodules and family history of malignant tumors. Cigarette smoking was negatively associated with the disease.
