Background Congenitally missing permanent teeth (CMPT) was recognized as a clinical and public health problem in pediatric dentistry. Aim To determine the prevalence of CMPT among orthodontic patients in Southern Croatia. Materials and Methods In a retrospective study, we analyzed CMPT in patients from three different regions in Southern Croatia (SC). Two orthodontic practices from each region were selected and a total of 4649 records of patients aged 6 - 15 years, who were clinically examined for orthodontic treatment between 2008 and 2015, were evaluated. We excluded 219 patients and 4430 patients remained for further analysis. Results There was no difference in prevalence of CMPT among regions in Southern Croatia, and the whole sample was evaluated. CMPT was found in 345(7.8%) patients. The highest proportion of CMPT was with one or two missing teeth 122 (81.9%) and 158 (80.6%), followed by those with three to five missing teeth or moderate hypodontia, 25(16.8%) and 35(17.9%), in males, and females respectively. Bilateral hypodontia of the lower second premolars and upper second incisors was more common than unilateral hypodontia. Conclusions The obtained results of high prevalence of CMPT in Southern Croatia reinforce the need for a timely diagnostics and treatment of moderate and severe cases.

Abstract Introduction. Numerous international and local organisations and agencies have in the past 15 years dealt with various issues and problems related to tourism in Bosnia and Herzegovina. Often, they have accentuated the large potential for tourism development and improvement, particularly when it comes to spa tourism. Although all elements necessary for development (tradition, accommodation capacities, natural resources, and traffic connections) are present, the “Banja Vrućica” spa is still unable to respond to modern tourism market demands so that it can contribute to the economic growth and development in the national and local economies. The successful running of a tourist destination requires the formulation of long-term goals and decisions, reached through a process of strategic management. The aim of this article is to use strategic analysis as a means of identifying the possibilities of introducing new sport-recreational offers with a higher quality of service provision aligned with consumer needs, which would help the Vrućica spa to become more attractive and profitable. Material and methods. After selecting factors of the internal and external environment which influence sport tourism at the spa, the intensity of the impact of each factor was determined through the use of SWOT analysis. Then, by multiplying the average impact of strengths, weaknesses, opportunities, and threats matched in the SWOT Matrix, a polygon SWOT analysis of the strategy was carried out. Conclusion. Having analysed the “Banja Vrućica” spa’s environment and having quantified the results, we reached the conclusion that the best solution is to form and implement a WO strategy with regard to sport tourism at the spa, meaning a shift in strategy aimed at keeping the existing activities and structures and developing new products and a new approach to the market.

Introduction Insulin therapy of pediatric patients with type 1 diabetes mellitus (T1DM) is highly demanding due to their dynamic growth, development and different daily life activities. Goal To determine the optimal insulin delivery method for the prevention of hypoglycemia recorded by continuous monitoring of glucose in patients with insulin pump and PEN. Material and Methods The study included patients up to 18 years of age with diagnosed T1DM and treated with insulin pump and by insulin therapy with PEN at the Pediatric Clinic of the Clinical Center in Sarajevo. The study involved 149 patients, and lasted for 3 years. Patients were divided into two groups: group of patients on insulin pump therapy and group on insulin PEN. Results There were 73 patients (49.6%) on insulin pump therapy and 79 patients (52.4%) on the insulin PEN therapy. There was no significant difference in the age between genders nor groups with different insulin application methods. There were no significant differences in the number of anamnestic hypoglycemia in patients with a different mode of insulin application (83.56% vs. 81.58%, p=0.114, F=2.533 < Fk=3.919). The number of hypoglycemia episodes in history is higher with the PEN therapy than in the insulin pump group. Conclusion The number of anamnesis hypoglycemia as well as hypoglycemia from CGM records did not differ significantly in patients with IP and PEN therapy. The CGM record was significantly more valuable in the presentation of hypoglycemia compared to the history of hypoglycemia in all patients studied. Continuous monitoring of glycemia due to the ability to show glycemia variability and unrecognized hypoglycemia as well as predictive options for long-term metabolic control should be performed for all T1DM patients at least once a year.

Relaying over power line communication (PLC) channels can considerably enhance the performance and reliability of PLC systems. This paper is dedicated to study and analyze the energy efficiency of multi-hop cooperative relaying PLC systems. Incremental decode-and-forward (IDF) relying is exploited to reduce the transmit power consumption. The PLC channel is assumed to experience log-normal fading with impulsive noise. The performances of single-hop and conventional DF relaying systems are also analyzed in terms of outage probability and energy efficiency for which analytical expressions are derived. Results show that using more relays can improve the outage probability performance; however, this is achieved at the expense of increased power consumption due to the increased static power of the relays, especially when the total source-to-destination distance is relatively small. Results also demonstrate that the IDF PLC system has better energy efficiency performance compared to the other schemes.
