Introduction. Castleman disease is a rare disease of the unknown etiology, occuring in two clinical forms: unicentric or multicentric. It is characterized by the hyperplasia of lymph glands. In literature the four pathohistological forms were described: hyaline vascular type, plasma cell type, mixed type and a recently recognized plasmablastic type. The most frequent changes are localized in the mediastinum, while the abdominal localization is with significantly rare occurrence, and that was the motive for presentation of this case. Case report. In a 41-year old male magnetic resonance (MR) enterography showed a change in the ileocecal area without the presence of subjective symptoms of digestive tract and without loss of body mass. Due to the suspicion of stromal tumor, surgical intervention was indicated. Pathohistological findings showed Castleman lymphadenopathia reactiva mesenterii (plasma cell type) which was in the unicentric form. There were present only anaemia and the increased value of sedimentation from the laboratory analyses. Conclusion. Abdominal localization of unicentric plasma cell form occurs rarely and the surgical method of treatment presents the golden standard as it was shown in the presented case. © 2017, Institut za Vojnomedicinske Naucne Informacije/Documentaciju.

Introduction/Objectives The shape and size of the orbital cavity are important parameters in planning surgical interventions and have significance in anthropology and forensic medicine. The aim of this study was to determine the morphometric characteristics of orbital cavity in Serbian population and to examine if there are differences in examined parameters between Serbs and the Roma Community of Serbia. Methods Using computer tomography and subsequent multiplanar reconstruction we analyzed orbits from 76 Serbian and 18 Roma healthy volunteers. There was no significant difference in age between the ethnicities. Results The height and width of the left orbit and the height of the right orbit were significantly higher in Roma group, whereas the width of the right orbit was not statistically different between ethnicities. Orbital indices, however, for both left and right orbit did not significantly differ between Serbian and Roma examinees. Right orbital volume did not differ between the groups, but left orbits had significantly larger volumes in Roma population. Finally, biorbital and interorbital width were both significantly higher in Roma than in Serbian examinees. We could not show differences between sexes except for the biorbital width, which had lower values in Serbian, but not Roma women than in men. Conclusion Taken together, our results indicate larger orbits, as well as greater distances between the eyes in Roma than in Serbian examinees. © 2022, Serbia Medical Society. All rights reserved.

Background/Aim. Preservation of an adequate posterior tibial slope (PTS) during total knee arthroplasty is crucial for the biomechanical stability and function of the knee joint. Studies that investigated anatomical features of the tibial plateau found significant gender and inter-population differences in all components of the PTS. The aim of this study was to establish reference values of PTS in Serbian population and to explore if there is any difference in the tibial plateau inclination between genders. Methods. We retrospectively reviewed 161 magnetic resonance images (MRIs) of the knee of adult patients examined in Medical Military Academy in Belgrade, Serbia, in a period from November 2011 to September 2014. Measurements of PTS components: medial tibial slope (MTS), lateral tibial slope (LTS), and coronal tibial slope (CTS) were performed through several steps, according to the suggestions in the recent literature. Obtained values for each tibial slope were compared between gender subgroups using appropriate statistical tests. Results. Mean values of each component of the posterior tibial slope for male vs. female subgroups were as follows: MTS 3.7° ± 2.8° vs. 5.1° ± 2.9°, LTS 4.2° ± 2.8° vs. 4.3° ± 2.7°, and CTS 3.9° ± 2.4° vs. 3.3° ± 1.9° respectively. The medial tibial slope was significantly higher in females than in males (p = 0.005). The mean value of the coronal tibial slope was greater in males without statistically significant difference (p = 0.105). Conclusion. This study demonstrated significant difference in MTS of the tibial plateau between males and females, being higher in the female subgroup. © 2018, Institut za Vojnomedicinske Naucne Informacije/Documentaciju.

Introduction. Surgical management of massive bone defects is very challenging in terms of estimating possibilities of saving the extremity and adequate method that can make it possible. Selection of methods is additionally limited in the presence of infection at site of defect. Case report. The female patient, diagnosed with Ewing sarcoma was treated by segmental bone resection and implantation of Kotz modular tumor endoprosthesis. After 5 years the signs of infection occured and persisted with low grade intensity. After falling, 12 years following implantation, the patient acquired periprosthetic fracture. Then endoprosthesis was removed, all along with surgical debridement of wound and application of the Ilizarov apparatus. The apparatus was applied, osteotomy of callus and the tibia performed with transport of bone segments, untill reconstruction of defect and arthrodesis of the knee was achieved. Conclusion. The Ilizarov apparatus offered us huge possibilities for management of massive bone defects with natural bone which has superior biomechanical characteristics comparing to the implant. The most frequent complication of this method is a prolonged treatment period that demands good patient selection and preparation and wide surgical experience. © 2016, Institut za Vojnomedicinske Naucne Informacije/Documentaciju.

Introduction. Malignant fibrous histiocytoma is a fast spreading pleomorphic sarcoma with a high malignant potential. Its spreading is characterized with local invasion and distant metastazes with early onset. Most common localisations of development are extremities, trunk and retroperitoneum. Given the line of rare case and specimen, lack of a clear etiology and mechanisms of this disease, as well as adequate histopathologic findings and intraoperative documentation, we presented current status, discuss putative etiology, histopathology with variant morphology, differential diagnosis and treatment modalities. Case report. We presented a 56-years-old female Serbian with tumor in the thigh that clinically resembles incapsulated hematoma. Computed tomography revealed intramuscular tumor with a heterodense structure and compression on surround tissue. Ex tempore biopsy specimen showed malignant potential of the tumor. Wide and radical excision of the nodule has been done, and definitive histopathological verification revealed malignant fibrous histiocytoma. Conclusion. Malignant fibrous histiocytoma is a most common type of soft tissue sarcomas in adults. Frequent localization is on lower extremities, and every rapidly enlarging nodule in this localization that on computed tomography is like incapsulated hematoma with necrotic zone should alert suspicion on presence of this type of sarcoma. © 2018, Inst.

Background/Aim. The most frequent form of sternal defects is a single foramen, usually located at the distal half of the sternal body, with prevalence that varies among different ethnic populations. Clinical importance of these defects arises from various diagnostic and therapeutic sternal treatments and close location of heart, lungs and other vital organs of the chest cavity. The aim of this study was to determine the prevalence and morphometric characteristics of the sternal midline foramen in the population of central Serbia. Methods. The multidetector computed tomography (MDCT) chest images of 422 patients of both genders were analyzed. The radiological imaging was performed on 64slice MDCT scanner (Aquilion 64, Toshiba, Japan). All scans were performed in the axial plane, with subsequent multiplanar reconstruction (MPR). Due to the angulation of the sternal body coronal curved-planar, the images were obtained in order to show the whole length of the sternum and the vertical diameter of the sternal foramen. The measurements were done using the commercially available soft ware (Imaging Software ver. 4.1.14.0, Vital-Images). Results. The solitary foramen, located in the distal segment of the sternal body, was detected in 24 patients, representing 5.9% of the observed population with slightly higher prevalence in males. The average size of foramen was 3.9 × 4.2 mm. The mean distance from the skin was 12.7 ± 3.3 mm, the distance from skin to pericardium was on average 37.3 ± 8.2 mm, while the average distance from skin to pleura was 25 ± 5.9 mm. The average depth of foramen 8.7 ± 2 mm, while the mean distance from the posterior surface of foramen to pericardium was 12.7 ± 9.1 mm. Conclusion. The results presented in this paper confirmed the prevalence of 5.9% regarding the midline sternal foramen in the observed population. Serious complications of the sternal puncture could be prevented by prior MDCT imaging. © 2019, Inst. Sci. inf., Univ. Defence in Belgrade. All rights reserved.

Background/Aim. The values of the Böhler’s angle (BA) are relevant parameters for diagnosis, management and prognosis of the calcaneal fracture and the outcome. Range of normal values of Böhler’s angle (BA) in adults varies depending on the examined population, age, gender or ethnicity. The aim of this study was to determine the range of normal values of the Böhler’s angle in the central part of Serbia. Methods. The lateral foot radiographs of 225 subjects (111 males and 114 females) without calcaneal fractures, divided into 6 age groups were observed to determine the normal values of the Böhler’s angle by using the IMPAX 6.5.2.114 Enterprise software. Obtained values for Böhler’s angle were compared among gender and groups using appropriate statistical tests. Results. The mean of Böhler’s angle in observed population was 34.06°, ranging from 25.1° to 49.5° and was higher in males than in females included in our study. Gender difference was statistically significant. The distribution of the mean BA across the age groups showed tendency of decreasing with age and the highest BA was found in the youngest group. Conclusion. The findings presented in this paper confirmed the existence of wide range of BA values as well as its gender and age differences. © 2018, Inst. Sci. inf., Univ. Defence in Belgrade.

Background/Aim. Determining the value of Gissane’s angle (GA) plays a role in the diagnosis and prognosis of heel fractures, determining treatment methods, and assessing the outcome of surgical treatment. Normal values of the GA vary in relation to ethnicity, age, and gender of the examined group, which indicates its anthropometric significance. The aim of this study was to determine the range of normal GA values in the population of Central Serbia. Methods. GA was determined on lateral radiography of the foot of 145 subjects of both sexes (67 women and 78 men), with subjects divided into 6 age groups. The patients included in the study did not have a calcaneus fracture. The obtained results were processed in the Graph Pad program. Results. The average value of GA in Central Serbia was 110.8° ± 8.1°, ranging from 93° to 132.9°. The mean value of GA decreased with age, and no difference was observed between women and men, except in the youngest age group, where women had higher GA values than men. Conclusion. The results of the study showed a wide range of normal GA values, as well as the existence of a difference in subjects of different ages and sex. © The Author(s) 2022.

Introduction. Percutaneous vertebroplasty (PVP), as a mini-invasive approach in the treatment of patients with osteoporotic vertebral compression fractures (OVCFs), provides stabilization of the spine and relives pain. The most commonly it is applied in the 3–6 weeks before bending of the spine. Complete cessation of pain is easier to achieve if you treat “less mature” fractures. The aim of the report is to show that PVP is effective and safe for old fractures too. Case report. A 77-old patient suffered from a stable compression fracture of 3th lumbar (L3) vertebral body after minor trauma. This fracture was clinically and radiologically diagnosed. The conservative treatment that included lumbo-sacral orthosis (LSO), analgesic drugs and physical therapy, was primarily applied due to permanent pain and type of fracture. After a period of two months, pain persisted, but it was localized in a thoracic spinal segment with radiologically diagnosed fractured bodies of 8th (Th8) and 10th (Th10), thoracic vertebra without neurological deficit. Thoraco-lumbo-sacral orthosis (TLSO) was prescribed and after six months the indication for vertebroplasty of the Th8 and Th10 vertebral body was given. The pain relief had been achieved and the patient was discharged from the Clinic for Orthopedics on the postoperative day 2, and was symptom free during the follow-up period. Conclusion. In patients with stable OVCFs, PVP is an effective therapy for reducing pain and improving mobility of 6 months old fractures. © 2018, Routledge. All rights reserved.
