ABSTRACT The objective of this study was to develop a locked tibial-plateau-leveling osteotomy (TPLO) plate and to compare this implant with the conventional bone fixation method using a locked plate to determine bone stabilization against torsion forces. Maximum force, angle at peak torque, and stiffness values were determined. Ten synthetic tibias were used, divided into 2 groups. The results in Group 1 (modified TPLO plate) and Group 2 (locked plate) were assessed using analysis of variance and the means were compared using Tukey’s test at 5% probability. There were significant differences in the angle at peak torque and stiffness. The group Modified TPLO plate had higher mean values of stiffness compared with Group locked plate. Group locked plate showed a greater angle at peak torque compared with Group modified TPLO plate. All constructs failed due to tibial fractures distal to the plate. The modified TPLO plate presented higher stiffness indexes than conventional locked plate in torsion. The locked plate presented greater elasticity than modified TPLO plate having greater angle at the peak of torque.

Summary Objective: To compare the effects of bandaging on immediate postoperative swelling using a modified Robert-Jones bandage after tibial plateau levelling osteotomy (TPLO) in dogs. Study design: Prospective case series. Methods: Dogs undergoing a TPLO were randomly placed into two groups. Group 1 received a modified Robert-Jones bandage postoperatively for a 24 hour period and Group 2 was not bandaged. Hindlimb circumference was measured at the level of the mid-patella, the distal aspect of the tibial crest, the midpoint of the tibial diaphysis and the hock. Measurements were recorded and compared in each group preoperatively and at 24 hours and 48 hours post-operatively. Interobserver variability was compared between the two observers. Results: There was no significant difference in postoperative swelling, as measured by the percentage change in circumference, between bandaged and unbandaged operated limbs after the TPLO at 24 and 48 hours at any site. Some significant differences in measurement at particular sites were observed between the two different observers, but there was a significant linear correlation at all sites between observers. The observer with the least experience consistently had slightly higher measurements at these sites. Clinical relevance: The use of a modified Robert-Jones bandage after TPLO did not prevent statistically significant postoperative swelling, and thus may not be indicated for this purpose. Postoperative bandages placed to control swelling after other small animal orthopaedic procedures should be evaluated individually for efficacy.

ABSTRACT Objective: The purpose of this study was to evaluate fracture resistance of teeth with immature apices treated with coronal placement of mineral trioxide aggregate (MTA), bioaggregate (BA), and Biodentine. Materials and Methods: Forty-one freshly extracted, single-rooted human premolar teeth were used for the study. At first, the root length was standardized to 9 mm. The crown-down technique was used for the preparation of the root canals using the rotary ProTaper system (Dentsply Maillefer, Ballaigues, Switzerland) of F3 (30). Peeso reamer no. 6 was stepped out from the apex to simulate an incompletely formed root. The prepared roots were randomly assigned to one control (n = 5) and three experimental (n = 12) groups, as described below. Group 1: White MTA (Angelus, Londrina, Brazil) was prepared as per the manufacturer's instructions and compacted into the root canal using MAP system (Dentsply Maillefer, Ballaigues, Switzerland) and condensed by pluggers (Angelus, Londrina, Brazil). Group 2: The canals were filled with DiaRoot-BA (DiaDent Group International, Canada). Group 3: Biodentine (Septodont, Saint Maur des Fosses, France) solution was mixed with the capsule powder and condensed using pluggers. Instron was used to determine the maximum horizontal load to fracture the tooth, placing the tip 3 mm incisal to the cementoenamel junction. Mean values of the fracture strength were compared by ANOVA followed by a post hoc test. P < 0.05 was considered statistically significant. Results: No significant difference was observed among the MTA, BA, and biodentine experimental groups. Conclusion: All the three materials tested, may be used as effective strengthening agents for immature teeth.

Introduction: The optimal treatment strategy for the proximal humeral fracture (PHF) remains controversial. The debate is centered around the correct treatment strategy in the elderly patient population. The present study investigated whether age predicts the functional outcome of locking plate osteosynthesis for this fracture entity. Methods: A consecutive series of patients with surgically treated displaced PHF between 01/2017 and 01/2018 was retrospectively analyzed. Patients were treated by locking plate osteosynthesis. The cohort was divided into two groups: Group 1 (≥65 years) and Group 2 (<65 years). At the follow-up examination, the SSV, CMS, ASES, and Oxford Shoulder Score (OS), as well as a radiological follow-up, was obtained. The quality of fracture reduction is evaluated according to Schnetzke et al. Results: Of the 95 patients, 79 were followed up (83.1%). Group 1 consists of 42 patients (age range: 65–89 years, FU: 25 months) and Group 2 of 37 patients (28–64 years, FU: 24 months). The clinical results showed no significant differences between both groups: SSV 73.4 ± 23.4% (Group 1) vs. 80.5 ± 189% (Group 2). CMS: 79.4 ± 21 vs. 81.9 ± 16, ASES: 77.2 ± 20.4 vs. 77.5 ± 23.1, OS: 39.5 ± 9.1 vs. 40.8 ± 8.2; OS: 39.5 ± 9.1 vs. 40.8 ± 8.2. In the radiological follow-up, fractures healed in all cases. Furthermore, the quality of fracture reduction in both groups is comparable without significant differences. The revision rate was 9.5% in Group 1 vs. 16.2% in Group 2. Discussion: Both age groups show comparable functional outcomes and complication rates. Thus, the locking plate osteosynthesis can be used irrespective of patient age; the treatment decision should instead be based on fracture morphology and individual patient factors.

Purpose. To evaluate the efficacy and safety of femtolaser-assisted phacoemulsification in glaucomatous eyes in the long-term follow-up. Materials and methods. A retrospective analysis of the results of the surgical treatment of patients with combined cataract and glaucoma pathology was analyzed. The patients were divided into groups depending on the method of surgical intervention: 1) phacoemulsification with femtolaser support (26 eyes, 23 patients); 2) phacoemulsification (36 eyes, 30 patients); Results. Before surgery, there were no statistically significant differences in IOP and corneal hysteresis (СН) between groups 1 and 2. The mean values of IOP cc, IOP g and СН of group 1 before surgery were 22.7±6.1 mm Hg, 20.9±6.9 mm Hg, 8.5±1.6 mm Hg; 2 group – 22.9±8.7 mm Hg, 21.6±8.9 mm Hg, 8.9±1.6 mm Hg respectively. Average values of IOP cc, IOP g and CН 5 years after the surgical treatment in group 1 were 15.3±1.2 mm Hg, 14.4±3.4 mm Hg, 9.6±4.2 mm Hg; in group 2 – 18.0±4.2 mm Hg, 16.1±4.2 mm Hg, 8.8±2.2 mm Hg respectively. In both groups, stabilization of IOP and CH indices was noted, which remained throughout the entire observation period, which shows the normalization of the biomechanical properties of the corneoscleral membrane of the eye in the long-term postoperative period. Conclusion. Femtolaser accompaniment of phacoemulsification is an effective and safe method of cataract surgery for combined pathology. Key words: femtolaser, cataract, glaucoma, phacoemulsification.

The aim of this study was to evaluate the influence of plantar short foot muscles exercises on the performance of lower extremities in long-distance runners. 47 long-distance runners aged 21-45 years took part in this study. The participants were divided into two groups based on baseline measurement of Foot Posture Index: Group 1 (n=27) with neutral foot and Group 2 (n=20) with slight and increased pronation. The participants performed the exercises daily for 6 weeks. The knee flexors and extensors torque, work, and power on Isokinetic Dynamometer and Running-Based Anaerobic Sprint Test (RAST) were checked at baseline and after 6 weeks of exercises. Higher values of peak torque of knee flexors were observed. This change was statistically significant at high load with angular velocity 90°/s (73.55 Nm at baseline and 89.05 Nm after 6 weeks) and 160°/s (69.40 Nm at baseline and 79.00 Nm after 6 weeks) in Group 2. In both groups higher values of maximum power were noted. Participants in Group 2 achieved lower values in each 35-metre run time and higher values of power. In Group 2 there was significant improvement of total time (35.26 s at baseline and 34.79 s after 6 weeks) compared to Group 1 (37.33 s at baseline and 37.56 s after 6 weeks). Exercises strengthening short foot muscles may improve energy transfer through body segments and increase strength and values of generated power. They should be included as a part of daily training programme of runners. This study was registered in the Australian New Zealand Clinical Trials Registry (ANZCTR).

AT III was measured in 34 patients with clinical and bacteriological evidence of septicaemia using a heparin cofactor assay. Based on the results of positive blood cultures gram-negative septicaemia (G-S) was diagnosed in 10 (group 1) and gram positive septicaemia (G+S) in 9 patients (group 2). From the remaining 15 patients {group 3) blood cultures before onset of antibiotic therapy were not obtained and gave negative results throughout the observation period. Based on bacteria] cultures from other sites than venous blood or bacteriological examination of spinal fluid G-S was assumed in 13 and G+S in 2 patients.In all but one patient of group 1 and one of group 2 AT III activities were decreased below 2 SO of normal controls (n = 91, x = 99.6, SD-8.4) already at the time of the first coagulation screening (patients: n=34, =58.4, SD-16.6). Analysis of var-ance showed no significant difference between the mean values of the three groups at the c per cent (%) level. The minimal AT III activities during the course of the disease were below the norma] range in all patients studied [n=34, =51.2, SD=13.6).Thus AT III deficiency appears to be a constant and early finding in G-S and G+S, causing insufficient inhibition of blood coagulation, and hereby may contribute to irreversible tissue damage caused by microthrombi in septic shock. This deficiency may be an important factor in the failure of heparin therapy to reduce mortality from septic shock.

<div class="WordSection1"><p><strong>Objectives</strong>. Interprofessional teamwork is best attained through education that promotes mutual trust and effective communication. The primary aim of the study was to evaluate the impact of interprofessional learning on knowledge about diabetes. <strong>Methods</strong>. The cross-sectional study included students of medicine, dentistry and nursing at the Faculty of Medicine Foča, Bosnia and Herzegovina. The students were randomly allocated into one of two groups. Group 1 attended an interprofessional course on diabetes while group 2 was divided into three subgroups and each of the subgroups attended an uniprofessional diabetes course. The measuring instrument used in the course in order to assess the participants’ knowledge about diabetic care was a test containing multiple-choice questions about diabetes. The Interprofessional Questionnaire was used to explore the attitudes, views, values and beliefs of students regarding interprofessional education (IPE). <strong>Results</strong>. No statistically significant difference in total score on the test was found between the groups at baseline, but at follow-up the difference was highly statistically significant (F=10.87; p=0.002). The students from Group 1 had better results (21.82 points), compared to Group 2 (18.77 points). The statistically significant difference was observed in mean values (t=-3.997; p=0.001), between Groups 1 and 2; the students from Group 1 obtained 20.42 points, which is considered to indicate a respectively positive self-assessment of communication and teamwork skills. However, Group 2 indicated a negative self-assessment of communication and teamwork skills. <strong>Conclusion</strong>. The findings suggest that IPE activities may provide health profession students with valuable collaborative learning opportunities.</p></div>

Objective: To perform morphometric analysis of corpus callosum (CC) by using callosal area (CA), supratentorial-supracallosal area (SSA) and CA/SSA parameters in a healthy pediatric population and to investigate changes according to age and gender. Method: Method: This retrospective study included a total of 313 children (154 boys, 159 girls) aged between 3-17 years. The cases were divided into three groups according to age: 3-6 years (Group 1) (pre-school), 7-12 years (Group 2) (preadolescent) and 13-17 years (Group 3) (adolescent). CA and SSA were measured on the mid-sagittal plane on T1-weighted images. CA/ SSA index was calculated. Differences in age, CA, SSA, and ratio parameters among the gender groups were compared using the Mann-Whitney U or the t-test. Results: Median values of CA (p= 0.002), mean values of SSA (p=0.001) and CA/SSA ratios (p= 0.04) were significantly higher in boys compared to girls. The median CA and mean CA/SSA ratios in Group 3 were significantly higher than Groups 1 and 2 (p= 0.001). Mean CA/SSA ratio values of boys and girls in Age Group 3 were significantly higher than Group 1 (p= 0.001) and significantly higher than Age Group 2 in girls. There were highly significant positive correlations of age with CA (p=0.001, r=0.47), SSA (p=0.028, r=0.12) and CA/SSA ratio (p=0.001, r=042). There was a highly significant and positive correlation between CA and SSA (p=0.001, r=0.25) and CA/SSA ratio (p=0.001, r=0.87). Conclusion: CA, SSA, and CA/ SSA ratio values in children are affected by age and gender. These parameters can be used as reference values for the diagnosis of congenital and acquired pathologies affecting the corpus callosum.

Purpose: To examine the differences between performing Nordic hamstring exercises once or twice a week on hamstring eccentric strength and other muscle-strain risk factors in high-level football players. Methods: In this randomized trial, 32 football players (18–23 y old) completed an 8-week Nordic hamstring exercise training program in 1 of 2 experimental groups: group 1 (once a week; n = 15) and group 2 (twice a week; n = 17). Knee-flexor/extensor peak torques and biceps femoris long-head muscle architecture were assessed through isokinetic dynamometry and ultrasonography, respectively, before and after the training programs. Analysis of covariance, effect sizes (ESs), and t tests for percentage change were used to assess the effect of the 2 interventions on the outcome measures. Results: Group 2 demonstrated higher hamstring concentric peak torque than group 1 posttraining (155–164 vs 149–158 N·m; P = .043; ES = 0.27), although there was also a statistical trend for higher hamstring eccentric peak torque (212–234 vs 198–221 N·m; P = .098; ES = 0.37), hamstring-to-quadriceps conventional ratio (0.56–0.59 vs 0.54–0.57; P = .089; ES = 0.31), and hamstring-to-quadriceps functional ratio (0.76–0.84 vs 0.71–0.79; P = .076; ES = 0.50). No between-groups differences were found for muscle thickness (P = .864; ES = 0.12), pennation angle (P = .289; ES = 0.18), fascicle length (P = .406; ES = 0.03), and quadriceps concentric peak torque (P = .340; ES = 0.02). Conclusion: Only the Nordic hamstring exercise training program performed twice a week strengthened the hamstrings of high-level football players, while similar changes in muscle architecture occurred with both once- and twice-weekly sessions.
