- Introduction: Granular Cell Tumors (GCTs) of the orbit are rare-entity soft-tissue tumors, and few reports have been published in the literature. The treatment of the choice is total excision. Early diagnosis prior to surgery is valuable for the distinction of malignant from benign tumor.Case presentation: We report a case of a 55-year-old woman with a solitary slow-growing mass in the right orbit with the involvement of the rectus inferior muscle, and present a review of the recent literature. The lesion had a diameter of 1 cm and was noticed 2 years before the examination. Excisional biopsy confirmed the diagnosis of GCT. The tumor was resected through a retroseptal transconjunctival approach. The final histological examination revealed findings characteristic of GCT, including positive reaction for protein S-100, SOX10, and calcitonin and negative reaction for desmin, myogenin, Smooth Muscle Antigen (SMA), Melan-A, and HMB-45. There were no signs of malignancy in this sample. Disturbance of motility was not noted by the patient after surgery.Conclusion: GCT should be included in the differential diagnosis of intraorbital lesions, particularly those that involve the orbit muscles. A biopsy is recommended before surgical resection, to exclude malignancy and prevent radical resection.

- ObjectivesThe treatment of fractures prioritizes the restoration of functionality through the realignment of fractured segments. Conventional methods, such as titanium plates, have been employed for this purpose; however, certain limitations have been observed, leading to the development of patient-specific plates. Furthermore, recent advancements in digital technology in dentistry enable the creation of virtual models and simulations of surgical procedures. The aim was to assess the clinical effectiveness of patient-specific plates utilizing digital technology in treating mandibular fractures compared to conventional titanium plates.Materials and methodsTwenty patients diagnosed with mandibular fractures were included and randomly assigned to either the study or control groups. The surgical procedure comprised reduction and internal fixation utilizing patient-specific plates generated through virtual surgery planning with digital models for the study group, while the control group underwent the same procedure with conventional titanium plates. Assessment criteria included the presence of malunion, infection, sensory disturbance, subjective occlusal disturbance and occlusal force in functional maximum intercuspation (MICP). Statistical analysis involved using the Chi-square test and one-way repeated measures analysis of variance.ResultsAll parameters showed no statistically significant differences between the study and control groups, except for the enhancement in occlusal force in functional MICP, where a statistically significant difference was observed (p = 0.000).ConclusionUsing patient-specific plates using digital technology has demonstrated clinical effectiveness in treating mandibular fractures, offering advantages of time efficiency and benefits for less experienced surgeons.Clinical relevancePatient-specific plates combined with digital technology can be clinically effective in mandibular fracture treatment.

Tidskriftsartikel (refereegranskat)abstract
- Present a case of a young patient with bilateral bony ankylosis of the TMJ with zero mouth opening treated with TMJ prosthesis.MethodsThe ankylosis was studied in detail with computed tomography (CT) and we used virtual surgical planning in the pre-operative phase to provide splints and cutting guides. The patient was treated with bilateral custom-made alloplastic TMJ prosthesis.ResultsOptimal functional improvement at the 5.5 year follow up after total joint reconstruction without any adverse effects. Mouth opening was 35 mm and the patient was free from pain. CT-images showed no signs of pathology or increased remodeling and bone formation.ConclusionAnkylosis of the TMJ in young and adult population presents unique challenges given the need to account for growth of the mandible and anatomical variations. This report supports the use of total joint reconstruction for end-stage TMJ disease.

Electric scooters accidents : Analyses of two Swedish accident data sets

Tidskriftsartikel (refereegranskat)abstract
- Since august 2018 electric scooters (e-scooters) are available in selected cities in Sweden, operated by several different operators. There is a growing concern regarding their safety as they grow in popularity. The aim with this study was to investigate injuries associated with e-scooters in Sweden and to identify accident characteristics. In addition, the aim was to observe how different data collection procedures and samples may influence the results. Two complementary data sets were used; insurance data including all reported injuries to Folksam Insurance Group during the period January 2019 to May 2020 and the Swedish Traffic Accident Data Acquisition database (STRADA), the national system for road traffic injury data collection, was used to study accident related to e-scooter use in the Stockholm city area between May and the end of August 2019. Most of the injuries associated with e-scooters occurred in single crashes, but in 13% of the accidents another road user was injured, either due to interactions with e-scooters or due to a parked e-scooter being a hazard. In both data sets more than half of the accidents occurred during weekends. In total 46% of all who had visited an emergency department the accident occurred during night-time (10 pm to 6 am). The overall large proportion of injuries to the head and face indicates the need for actions aimed to increase helmet use among e-scooter riders. Local authorities should take a wider responsibility since one third of all accidents primarily occurred due to lack of maintenance or that the rider hit a curb stone. In comparison to hospital data, insurance claims include riders with all types of injuries irrespectively what type of healthcare the rider was seeking. Hence, to better understand the consequences and to make the right decisions regarding countermeasures aimed to improve the safety of e-scooter riding, data from different data source are needed.
