OBJECTIVES
To quantify the volume and nature of radiological imaging performed for e-scooter related trauma presentations in a tertiary referral centre and to identify common radiological pattern of injuries.
METHODS
Our study received institutional review board approval. We retrospectively reviewed all anonymised radiological imaging studies performed in our institution for the term 'scooter' or 'e-scooter' between July 2020 and July 2021. The patient demographics, number of imaging studies performed and modality type as well as the nature of injuries identified were recorded.
RESULTS
Within the study period, 147 patients with e-scooter-related injuries were referred for radiological imaging. Forty-two (29%) of those patients had positive radiological findings. The vast majority of injuries on radiographs were upper limb injuries typical of a fall on outstretched hand (FOOSH) pattern. Thirty-two patients (22%) required advanced diagnostics with CT or MRI with 11 of these patients having positive findings. Four patients suffered significant head injuries including skull fractures and/or intracranial haemorrhage. Five patients suffered facial bone fractures, and 2 suffered spinal fractures. One patient suffered a handlebar abdominal trauma with a resulting large bowel injury ultimately requiring bowel resection.
CONCLUSION
E-scooter-related injuries represent a new and emerging high-energy trauma patient. These patients demonstrate injury patterns similar to other high-energy trauma such as road traffic accidents. Although the most common injuries are musculoskeletal upper limb injuries typical of FOOSH, a large proportion of these require advanced diagnostic imaging (CT, MRI) which were commonly positive for significant injuries.

Isolated coronoid process fractures are uncommon, and iatrogenic isolated fractures are extremely rare. This case describes a displaced fracture of an isolated coronoid process thought to be due to excessive force applied by a dentist that had been overlooked and left untreated for about a month. The patient was a woman in her late 50's and she had undergone a molar extraction. Her dentist had confused her symptoms of trismus, pain, and facial oedema with the complex tooth extraction procedure. Following a cone-beam computed tomography (CBCT) scan we showed that the mandibular coronoid process on her right side had suffered a longitudinal fracture, and the fractured fragment had rotated upwards and inwards. Following successful surgical elimination of the fragmented coronoid process, the patient received targeted physiotherapy sessions that yielded excellent results. At the five-month follow-up, the ability of the patient to open her mouth had improved enormously, and her facial appearance almost recovered to its original state.

BACKGROUND
Benign paroxysmal positional vertigo (BPPV) affects approximately half of acute, moderate-severe traumatic brain injury (TBI) patients. To date, there have been no rigorous studies of BPPV assessment or treatment in this cohort. We aimed to determine the safety, practicability, and efficacy of therapist-led BPPV management in acute TBI and the feasibility of a larger effectiveness trial.
METHODS
This was a multi-centre, three-arm, parallel-groups, randomised, feasibility trial. Recruitment was via convenience sampling. The main inclusion criteria were age over 18 years and a confirmed, non-penetrating, acute TBI. BPPV-positive patients were randomly allocated to one of three interventions (repositioning manoeuvres, Brandt-Daroff exercises or advice) using minimisation criteria. Outcome assessors were blinded to the intervention.
RESULTS
Of 2014 patients screened for inclusion, 180 were assessed for BPPV. Of those assessed, 34% (62/180) had BPPV, and 58 patients received an intervention. Therapist-led interventions were delivered safely and accurately according to intervention monitoring criteria. Resolution of BPPV was observed in 35/58 (60%) patients. The resolution rate was highest following repositioning manoeuvres (78%), followed by the advice (53%) and Brandt-Daroff interventions (42%). 10 patients experienced recurrence. This was observed more frequently in those with skull fractures and bilateral or mixed BPPV.
CONCLUSIONS
Overall, the results provide strong evidence for the feasibility of a future trial. Therapist-led management of BPPV in acute TBI was safe and practicable. Repositioning manoeuvres seemingly yielded a superior treatment effect. However, given the high recurrence rate of post-traumatic BPPV, the optimal time to treat according to patients' specific recurrence risk requires further investigation.

BACKGROUND
Traumatic internal carotid artery (ICA) occlusion is a rare complication of skull base fractures, characterized by high mortality and disability rates, and poor prognosis. Therefore, timely discovery and correct management are crucial for saving the lives of such patients and improving their prognosis. This article retrospectively analyzed the imaging and clinical data of three patients, to explore the imaging characteristics and treatment strategies for carotid artery occlusion, combined with severe skull base fractures.
CASE SUMMARY
This case included three patients, all male, aged 21, 63, and 16 years. They underwent plain film skull computed tomography (CT) examination at the onset of their illnesses, which revealed fractures at the bases of their skulls. Ultimately, these cases were definitively diagnosed through CT angiography (CTA) examinations. The first patient did not receive surgical treatment, only anticoagulation therapy, and recovered smoothly with no residual limb dysfunction (Case 1). The other two patients both developed intracranial hypertension and underwent decompressive craniectomy. One of these patients had high intracranial pressure and significant brain swelling postoperatively, leading the family to choose to take him home (Case 2). The other patient also underwent decompressive craniectomy and recovered well postoperatively with only mild limb motor dysfunction (Case 3). We retrieved literature from PubMed on skull base fractures causing ICA occlusion to determine the imaging characteristics and treatment strategies for this type of disease.
CONCLUSION
For patients with cranial trauma combined with skull base fractures, it is essential to complete a CTA examination as soon as possible, to screen for blunt cerebrovascular injury.

BACKGROUND
Children aged 0-4 years have the highest rate of emergency department (ED) visits for traumatic brain injury (TBI); falls are the leading cause. Infants younger than 2 years are more likely to sustain a fractured skull after a fall.
OBJECTIVE
This study examined caregiver actions and products associated with ED visits for fall-related fractured skulls in infants aged 0-4 months.
METHODS
Data were analyzed from the 2001-2017 National Electronic Injury Surveillance System-All Injury Program. Case narratives of infants aged 0-4 months who visited an ED for a fall-related skull fracture were examined to code caregiver actions preceding the fall. Product codes determined fall location and product type involved (e.g., flooring, bed, or stairs). All national estimates were weighted.
RESULTS
There were more than 27,000 ED visits (weighted estimate) of infants aged 0-4 months for a nonfatal fall-related fractured skull between 2001 and 2017. Most were younger than 2 months (46.7%) and male (54.4%). Falls occurred primarily in the home (69.9%) and required hospitalization (76.4%). Primary caregiver actions coded involved placing (58.6%), dropping (22.7%), and carrying an infant (16.6%). Floor surfaces were the most common product (mentioned in 24.0% of the cases).
CONCLUSIONS
Fall-related fractured skulls are a health and developmental concern for infants, highlighting the importance of a comprehensive assessment at the time of the injury to better understand adult actions. Findings indicated the need to develop prevention messages that include safe carrying and placement of infants.

Review
OBJECTIVE
Acromegaly is a disorder associated with excessive levels of growth hormone (GH) and insulin-like growth factor-1 (IGF-1). In general, GH/IGF-1 excess leads to morphologic craniofacial and acral changes as well as cardiometabolic complications, but the phenotypic changes and clinical presentation of acromegaly differ across species. Here, we review the pathophysiology, clinical presentation and management of acromegaly in humans and cats, and we provide a systematic comparison between this disease across these different species.
DESIGN
A comprehensive literature review of pathophysiology, clinical features, diagnosis and management of acromegaly in humans and in cats was performed.
RESULTS
Acromegaly is associated with prominent craniofacial changes in both species: frontal bossing, enlarged nose, ears and lips, and protuberant cheekbones are typically encountered in humans, whereas increased width of the head and skull enlargement are commonly found in cats. Malocclusion, prognathism, dental diastema and upper airway obstruction by soft tissue enlargement are reported in both species, as well as continuous growth and widening of extremities resulting in osteoarticular compromise. Increase of articular joint cartilage thickness, vertebral fractures and spine malalignment is more evident in humans, while arthropathy and spondylosis deformans may also occur in cats. Generalized organomegaly is equally observed in both species. Other similarities between humans and cats with acromegaly include heart failure, ventricular hypertrophy, diabetes mellitus, and an overall increased cardiometabolic risk. In GH-secreting pituitary tumours, local compressive effects and behavioral changes are mostly observed in humans, but also present in cats. Cutis verticis gyrata and skin tags are exclusively found in humans, while palmigrade/plantigrade stance may occur in some acromegalic cats. Serum IGF-1 is used for acromegaly diagnosis in both species, but an oral glucose tolerance test with GH measurement is only useful in humans, as glucose load does not inhibit GH secretion in cats. Imaging studies are regularly performed in both species after biochemical diagnosis of acromegaly. Hypophysectomy is the first line treatment for humans and cats, although not always available in veterinary medicine.
CONCLUSION
Acromegaly in humans and cats has substantial similarities, as a result of common pathophysiological mechanisms, however species-specific features may be found.

BACKGROUND
2-[F]fluoro-2-deoxy-D-glucose ([F]FDG) positron emission tomography combined with low-dose computed tomography (PET/CT) can be used at diagnosis to identify myeloma-defining events and also provides prognostic factors. The aim of this study was to assess the prognostic significance of baseline [F]FDG PET/CT visual IMPeTUs (Italian myeloma criteria for PET Use)-based parameters and/or total metabolic tumor volume (TMTV) in a single-center population of patients with newly diagnosed multiple myeloma (NDMM) eligible for transplantation.
METHODS
Patients with MM who underwent a baseline [F]FDG PET/CT were retrospectively selected from a large internal database of the University Hospital of Liege (Liege, Belgium). Initially, all PET/CT images were visually analyzed using IMPeTUs criteria, followed by delineation of TMTV using a semi-automatic lesion delineation workflow, including [F]FDG-positive MM focal lesions (FL) with an absolute SUV threshold set at 4.0. In a first step, to ensure PET/CT scans accurate reporting, the agreement between two nuclear medicine physicians with distinct experience was assessed. In the second step, univariable and multivariable analyses were conducted to determine the prognostic significance of [F]FDG PET/CT parameters on progression free survival (PFS) and overall survival (OS), respectively.
RESULTS
A total of 40 patients with NDMM were included in the study. The observers agreement in the analysis [18F]FDG PET/CT images was substantial for the presence of spine FL, extra spine FL, at least one fracture and paramedullary disease (Cohen's kappa 0.79, 0.87, 0.75 and 0.64, respectively). For the presence of skull FL and extramedullary disease the agreement was moderate (Cohen's kappa 0.56 and 0.53, respectively). Among [F]FDG PET/CT parameters, a high number of delineated volumes of interest (VOI) using the SUV4.0 threshold was the only independent prognostic factor associated with PFS [HR (95% CI): 1.03 (1.004-1.05), P = 0.019] while a high number of FL (n > 10; F group 4) was the only independent prognostic factor associated with OS [HR (95% CI): 19.10 (1.90-191.95), P = 0.01].
CONCLUSION
Our work confirms the reproducibility IMPeTUs criteria. Furthermore, it demonstrates that a high number of FL (n > 10; IMPeTUs F group 4), reflecting a high [F]FDG-avid tumor burden, is an independent prognostic factor for OS. The prognostic value of the TMTV delineated using a SUV4.0 threshold was not significant. Nevertheless, the count of delineated [F]FDG-avid lesions VOI using a SUV4.0 threshold was an independent prognostic factor for PFS.

With the recent increase in traffic accidents, pelvic fractures are increasing, second only to skull fractures, in terms of mortality and risk of complications. Research is actively being conducted on the treatment of intra-abdominal bleeding, the primary cause of death related to pelvic fractures. Considerable preliminary research has also been performed on segmenting tumors and organs. However, studies on clinically useful algorithms for bone and pelvic segmentation, based on developed models, are limited. In this study, we explored the potential of deep-learning models presented in previous studies to accurately segment pelvic regions in X-ray images. Data were collected from X-ray images of 940 patients aged 18 or older at Gachon University Gil Hospital from January 2015 to December 2022. To segment the pelvis, Attention U-Net, Swin U-Net, and U-Net were trained, thereby comparing and analyzing the results using five-fold cross-validation. The Swin U-Net model displayed relatively high performance compared to Attention U-Net and U-Net models, achieving an average sensitivity, specificity, accuracy, and dice similarity coefficient of 96.77%, of 98.50%, 98.03%, and 96.32%, respectively.

OBJECTIVE
Research on reasons for malpractice claims in oral and maxillofacial surgery is scarce. The aim of this study was to investigate the causes and prevalence of permanent harm among craniofacial fracture related malpractice claims.
MATERIALS AND METHODS
A retrospective register study was designed and implemented. All patients with a complaint and a diagnosis of facial or cranial fracture were included. The main outcome was the presence of permanent harm, and the predictor variable was the cause of complaint. Chi-square test was used for estimation of statistical significance.
RESULTS
Delay in correct diagnosis was the leading cause of malpractice claims (63.2%), and permanent harm was found in 23.1% of the population. 82.4% of injuries were facial fractures in total population. 65.3% (n = 98) of facial trauma were related with delayed diagnostics (p < 0.001). Permanent harm was more frequent in patients with delayed diagnosis (71.4%) than those without (60.7%, p = 0.299).
CONCLUSIONS
Claims of craniofacial trauma are related with under-diagnostics, and un-diagnosed facial fracture can lead to a high rate of permanent harm. Systematic clinical evaluation and facial trauma specialist consultation is recommended to set early correct diagnosis for and improve treatment of craniofacial trauma patients.
