Role of synbiotics in reducing postoperative infections in patients with hip fracture: pilot study
Authors: Pevec Teodor 
Published: February 2023

Purpose: Despite the development of surgical methods, infections continue to be serious postoperative complications. Probiotics have been shown to be effective in reducing the prevalence of infections. We explored the effectiveness of probiotics in reducing the prevalence of infections in subjects undergoing surgery for hip fractures.
Methods: Fifty-one patients admitted for surgical treatment of hip fractures were divided randomly into two groups: Synbiotic 2000 Forte and placebo. The occurrence of infection was closely observed upon hospital admission until the fifth postoperative day using, among other parameters, the C-reactive protein (CRP) level. Additionally, the patients’ tolerance to Synbiotic 2000 Forte was established using subjective (self-reported problems) and objective means.
Results: Infection was confirmed in 4 patients in each group. Urinary tract infection was noted in 7 subjects and a local wound infection in 1 patient. No differences were found in CRP levels upon hospital admission and the fifth postoperative day. Tolerance to Synbiotic 2000 Forte was lower in patients undergoing placebo treatment.
Conclusion: Synbiotic 2000 Forte did not reduce the number of postoperative infections. Further studies are needed to confirm these findings.
Open-Source Software in Medical Imaging: Case-Based Study with Interdisciplinary Innovative Product Design
Authors: Harih Gregor , Čretnik Andrej 
Published: February 2023

Purpose: Recently, comprehensive open-source software (OSS) solutions for medical images have been developed. They offer powerful tools for the management, visualization, storage and analysis of images. The purpose of the present study was to present the features and use of OSS in comparison with commercial software solutions when evaluating medical images.
Methods: A case study of the development of a tool handle of optimal size and shape using the free OSS “3D Slicer” is presented. Many authors recommend cylindrical-shaped handles to increase comfort, performance and to avoid cumulative trauma, but none have considered the optimal shape of the handle. Hence, we derived a method for obtainingan optimally shaped tool handle based on the power grip hand posture and non-deformed soft tissue. During magnetic resonance imaging (MRI), an outer hand mold was used to maintain the optimal hand posture. 3D Slicer was used for segmentation and 3D reconstruction of MRI. A three-dimensional (3D) hand model was exported to a commercial program for computer-aided design for the optimal tool handle.
Results: Measurements of the diameters on 3D reconstruction showed that the position of fingers wasere withheld within small deviations, which maximized maximum finger force exertion. An optimally shaped handle this way provided 25% higher contact area compared with the optimal cylindrical handle. It therefore reduced contact pressure, increased performance and comfort and could probably prevent disorders due to cumulative trauma.
Conclusion: This case study supported the use of OSS for medical imaging as a powerful and (mostly) free tool comparable with (usually expensive) commercial solutions.
Surgical treatment of acute patellar dislocation associated with bony avulsion in children
Authors: Fokter Samo K. , Dovnik Andraž , Fokter Dovnik Nina 
Published: February 2023

Purpose: The management of acute patellar dislocation in children and adolescents is controversial. Traditionally, most first–time traumatic patellar dislocations have been treated nonoperatively. However, due to new knowledge about medial patellar stabilizers some authors have advocated for surgical repair. The present report describes the mid–term subjective and functional results of operative treatment of acute patellar dislocation in children less than eighteen years of age with concomitant osteochondral fracture.
Methods: Data on a cohort of sixteen patients (eight girls and eight boys) aged 14.9 years (mean, range 12–17 years) with acute patellar dislocation were retrospectively collected. Intraarticular fragments were detected in all patients in conventional radiographs. Operative treatment consisted of arthroscopic removal (12 cases) or refixation (4 cases) of the osteochondral fragments and direct repair of the damaged medial patellofemoral ligament (MPFL) if that was still feasible (13 cases). All patients were seen at six months, and a telephone interview with twelve patients (75%) was conducted at four years (mean, range 2–7 years).
Results: Of the sixteen patients, two (12.5%) had a recurrent patellar luxation. The subjective IKDC score at the time of the most recent follow–up was 86 (mean, range 63–100), and the Marx Activity Rating Scale score was 9.2 (mean, range 2–16).
Conclusions: Direct surgical repair of the injured MPFL may be considered an option to prevent subsequent dislocation and subluxation in first–time traumatic dislocation of the patella in children and adolescents with osteochondral fractures and substantial disruption of medial patellar stabilizers.
Increased adherence to treatment guidelines for lower urinary tract infections in out–of–hours primary care settings following a simple intervention strategy
Authors: Klemenc–Ketiš Zalika , Kersnik Janko 
Published: February 2023

Aim: The aim of this study was to determine whether a simple intervention could foster adherence to treatment guidelines in women with uncomplicated lower urinary tract infections (LUTIs) in after–hours primary care settings.
Methods: This was a cluster, randomised, prospective intervention study in female patients conducted in 20 out–of–hours primary care (OOHC) settings in Slovenia (10 in the intervention group and 10 in the control group). In each OOHC centre, we included 10 consecutive patients with LUTIs who sought evaluation by a physician, called in for advice, or called in for a home visit. The OOHC centres in the intervention group received a poster with a schematic presentation of LUTI treatment treatment guidelines, which was displayed on the wall in the OHC practice.
Results: Of 20 OOHC centres, 14 were willing to participate in the study (seven in the intervention group and seven in the control group). The final sample consisted of 118 (59.0%) female patients (64 in the intervention group and 54 in the control group). The mean age of the sample was 43.2 ± 17.3 years (40.2 ± 16.4 years in the intervention group and 46.7 ± 17.8 years in the control group). Adherence to guidelines was confirmed in 42 patients (32 in the intervention group and 10 in the control group; p = 0.004).
Conclusions: A simple intervention can significantly enhance the adherence to treatment guidelines in patients with LUTIs managed in an OOHC centre.
Spectral domain optical coherence tomography for detecting glaucoma
Authors: Vrzel Dejan , Gračner Tomaž 
Published: February 2023

Purpose: To evaluate the diagnostic ability of macular thickness parameters and peripapillary retinal nerve fiber layer (RNFL) thickness parameters for detecting glaucoma using spectral domain optical coherence tomography (SD–OCT).
Methods: 37 eyes of 20 glaucoma patients and 30 eyes of 16 healthy subjects included in this study underwent macular and peripapillary RNFL scans with SD–OCT using standard scanning parameters. The ”Macular Cube 512x128” scan protocol was used to measure the macular thickness. The ”Optic Disc Cube 200x200” scan protocol was used for assessing the peripapillary region. The discrimination power of all parameters for detecting glaucoma was determined by the Area under Receiver Operating Characteristics (AROC) curve and sensitivity at fixed specificity, followed by a comparison of the best macular thickness and peripapillary RNFL thickness parameters.
Results: Significant differences between glaucoma patients and healthy subjects were found in all peripapillary RNFL thickness parameters and all macular thickness parameters, except in the fovea (p=0.322). The largest AROC with sensitivity at >90% specificity among the peripapillary RNFL thickness parameters was found for the average peripapillary RNFL thickness (AROC 0.95, sensitivity 76%). The largest AROC with sensitivity at >90% specificity among the macular parameters was found for the inferior inner macular thickness (AROC 0.90, sensitivity 78%). There was no statistically significant difference between the AROCs of these two parameters (p=0.208).
Conclusion: To discriminate glaucoma patients from healthy subjects using SD–OCT, macular thickness parameters had high diagnostic ability which was comparable to that of the peripapillary RNFL thickness parameters.
La fuente escrita como elemento corroborativo de los cambios fónicos: evidencia onomástica
Authors: Cerrón-Palomino Rodolfo , Cangahuala Castro Sergio 
Published: February 2023

La etimología científica, en contraposición a la ingenua o a la puramente impresionista, encuentra su más sólido respaldo en la lingüística histórica; y, en esta, en su conquista de la regularidad del cambio fonético. Y es que en virtud de dicho atributo el investigador, en este caso el etimólogo, puede no solo dar con el étimo de un término del cual no estaba seguro, sino que, apoyado en la regularidad del cambio, puede predecirlo, sobreponiéndose incluso ante la ausencia del corpus corroborativo disponible a la mano. El material confirmativo de una proyección etimológica puede encontrarse, sea con el descubrimiento de formas dialectales novedosas no entrevistas previamente o también en virtud de la evidencia insospechada aportada por el registro escrito filológicamente interpretado. La presente exposición procede en el siguiente orden: luego de una introducción general sobre el desarrollo de la lingüística histórica en el área andina, centramos nuestra discusión en el cambio fónico regular y su carácter predictivo en los estudios de lingüística andina con evidencias corroborativas tanto de naturaleza dialectal como documental (impresa), para luego, en una cuarta instancia, aportar testimonio manuscrito novedoso y revelador. La evidencia documental impresa o inédita gira en torno a la etimología de términos onomásticos como el de <Inca>, título nobiliario, y el de <Yauyos>, un etnotopónimo.
