PurposeTo investigate whether the surgical technique of single-bundle anterior cruciate ligament (ACL) reconstruction, the visualization of anatomic surgical factors and the presence or absence of concomitant injuries at primary ACL reconstruction are able to predict patient-reported success and failure. The hypothesis of this study was that anatomic single-bundle surgical procedures would be predictive of patient-reported success.MethodsThis cohort study was based on data from the Swedish National Knee Ligament Register during the period of 1 January 2005 through 31 December 2014. Patients who underwent primary single-bundle ACL reconstruction with hamstring tendons were included. Details on surgical technique were collected using an online questionnaire comprising essential anatomic anterior cruciate ligament reconstruction scoring checklist items, defined as the utilization of accessory medial portal drilling, anatomic tunnel placement, the visualization of insertion sites and pertinent landmarks. A univariate logistic regression model adjusted for age and gender was used to determine predictors of patient-reported success and failure, i.e. 20th and 80th percentile, respectively, in the Knee injury and Osteoarthritis Outcome Score (KOOS), 2 years after ACL reconstruction.ResultsIn the 6889 included patients, the surgical technique used for single-bundle ACL reconstruction did not predict the predefined patient-reported success or patient-reported failure in the KOOS4. Patient-reported success was predicted by the absence of concomitant injury to the meniscus (OR = 0.81 [95% CI, 0.72–0.92], p = 0.001) and articular cartilage (OR = 0.70 [95% CI, 0.61–0.81], p < 0.001). Patient-reported failure was predicted by the presence of a concomitant injury to the articular cartilage (OR = 1.27 [95% CI, 1.11–1.44], p < 0.001).ConclusionSurgical techniques used in primary single-bundle ACL reconstruction did not predict the KOOS 2 years after the reconstruction. However, the absence of concomitant injuries at index surgery predicted patient-reported success in the KOOS. The results provide further evidence that concomitant injuries at ACL reconstruction affect subjective knee function and a detailed knowledge of the treatment of these concomitant injuries is needed.Level of evidenceRetrospective cohort study, Level III.

OBJECTIVE The study was conducted to evaluate the Index of Orthodontic Treatment Need based on the Dental Health Component (DHC). MATERIALS AND METHODS 300 students aged 12-15 years were included in this study. The examinations were performed in two elementary schools in the municipality of Prozor-Rama, using standard dental instruments. Children were ranked into five grades according to the DHC. RESULTS Only 12% of children were found not to have a need for orthodontic treatment. Of the others, 45.33% had a great, and 10% a very great need for orthodontic treatment. The rest of the children were found to have a need for minor or moderate orthodontic treatment. Slightly more girls than boys had a great or a very great need for treatment, although the difference by gender was not statistically significant. Analysis of the level of need by age of children showed no significant difference; children with a great need of orthodontic treatment prevailed in all age groups. About 85% of children with a great and a very great need for orthodontic treatment would agree to orthodontic treatment, while the rate of non-acceptance was about 5%. CONCLUSION The high rate of need for orthodontic treatment in the examined students is explained by the lack of programs for this type of health care, the insufficient number of qualified orthodontic specialists, and the very low percentage of allocations from the state budget for oral health.

Electron-ion radiative recombination assisted by a bichromatic (two-component) elliptically polarized laser field is analyzed in the frame of the $S\text{-matrix}$ theory. The second Born approximation is applied in the expansion of the $S\text{-matrix}$ element where the first term in the expansion corresponds to the direct recombination of electrons with ionic targets, while the second term corresponds to the recombination preceded by an electron-ion scattering. The latter process is possible in the presence of a laser field. If the electron scatters on an ionic target, it may be subsequently driven back by the laser field and recombine with the same ion. The photon emitted in this process may have a high energy. We have studied the dependence of the energy spectrum on various laser-field and incident electron parameters. The energy spectra obtained show plateaulike structures with abrupt cutoffs. These cutoffs are explained by a classical analysis.

Raspberry cultivars are clonally propagated and therefore all plants belonging to a single cultivar represent the same genotype. Cultivar integrity of raspberry plantlings placed on the market in Bosnia and Herzegovina (B&H) is based on examining of morphological traits, which is not a reliable tool for genetic identification. In this study plantlings declared as cultivar ‘Polana’ were genotyped using seven microsatellites, in order to gain preliminary insight into the genetic integrity of raspberry plantlings marketed in B&H. Plant tissue (leaves) from 10 raspberry plants were randomly sampled from a batch of plantlings sold by major fruit nursery in Bosnia and Herzegovina. Along with these samples, four reference cultivars with confirmed identity (‘Polka’, ‘Autumn Bliss’, ‘Heritage’ and ‘Polana’) were also included in the study. Seven primer pairs amplified 31 alleles, or on average 4.4 alleles per locus. UPGMA cluster analysis, based on the Jaccard similarity coefficient, revealed that among the ten samples declared as ‘Polana’ plantlings only five were genetically identical to any of the other samples. The cluster analyses also exposed that none of the ten samples declared as ‘Polana’ seedlings were in fact identical or even closely related to the ‘Polana’ reference cultivar or any of the other reference cultivars. These findings clearly show that the genetic identity of primocane raspberry plantlings , currently sold in Bosnia and Herzegovina, needs to be tested using objective and reliable methods rather than simple morphologic observation.

UDK: 630*38:625.711.84(497.6 Trnovo) The forest truck roads, as one of the essential conditions for implementation of the planned biotechnical measures in the management unit, have to have an adequate quantity and quality. The aim of this research is determination of quantity and quality of the forest truck roads in the Management Unit (MU) „Gornja Rakitnica“, Forest Management Region (FMR) „Trnovsko“. The accessibility through wider categories of forest and total accessibility for MU have been calculated by the analysis of quantities indicators of the primary network of roads. The accessibility of the most important category of forests, from economy aspect, has been calculated – the forests with natural renewal. This accessibility amounts 12,7 m/ha. By the comparison of the values with the recommended minimum and optimum accessibility, it has been calculated that it is necessary to construct new forest truck roads. The data about quality have been obtained on the basis of terrain measurements in two forest truck roads „Rakitnica-Zućina vrela“ and „Pijevac – Borovac“. By the analysis of qualitative indicators in the analyzed roads it has been concluded that the network of forest truck roads in the MU „Gornja Rakitnica“ is passable i.e. it enables implementation of planned activities from all forest fields. The technical elements of the measured roads enable the values defined by technical regulations. The constructive elements: carriageway condition, slope cuttings, ditches and objects on the road are not in an adequate condition. If the adequate recovery works are not undertaken it could cause progressive deterioration of roads, which could influence functionality of roads transport of timber, access to compartments, etc… For the improvement of the condition of forest truck roads, the measures of recovery have been designed and the calculation of total and average costs has been carried out.
