Introduction: Incidence of diffuse axonal injury has been estimated at 40-50% of hospitalizations. Recently, much interest has been directed towards the potential of newer imaging sequences of magnetic resonance imaging to investigate diffuse axonal injury (DAI) and to prognosticate the outcome. In this study, we correlated the magnetic resonance imaging grades of diffuse axonal injury with clinical outcome in terms of Glasgow Outcome Scale (GOS). Methods and Materials: A hospital based observational study was carried out at Upendra Devkota Memorial National Institute of Neurological and Allied Sciences, Kathmandu in 69 patients of diffuse axonal injury between November 2017 to November 2018. Data was collected on patient and trauma characteristics, as well as neurological assessment and MRI findings. Outcome was assessed as favourable and unfavourable GOS for various MRI grades of diffuse axonal injury. Results: There were 21.74%, 42.03% and 36.23% of cases with grade I, II and III diffuse axonal injury respectively. There were 0 (0%), 2 (11.8%) and 15 (88.2%) cases of MRI grade I, II and III diffuse axonal injury in favourable GOS group and 15 (28.8%), 27 (51.9%) and 10 (19.2%) cases of MRI grade I, II and III diffuse axonal injury in unfavourable GOS group (p=0.00). Conclusion: This study showed that there was a significantly higher chance of unfavourable outcome with increasing MRI grades of diffuse axonal injury.

Background: Perinatal asphyxia is a significant cause of neonatal mortality and morbidity. MRI is useful for assessing the severity and pattern of brain injuries. There is less data of MRI findings of perinatal asphyxia from India and the subcontinents. This prospective observational study was done to describe MRI brain findings in neonates with perinatal asphyxia with respect to various determinants.Methods:  Initial MRI brain was done when babies were stable after fulfilling inclusion criteria. Immediate outcome was assessed at the end of hospital stay. They were followed up for presence of any sequel up to 1 year. Repeat MRI brain was done in few selected babies. Data was collected and statistically analyzed.Results: Total 55 babies were included in the study (term 27, preterm 28). There were 9 babies in stage 1, 17 babies in stage II and 22 babies in stage III. MRI brain findings were normal in 8 and abnormal in 47 patients. There were Deep gray matter injury (DG) in 22, Para Sagittal subcortical white matter injury (PS) in 6, Germinal matrix haemorrage (GMH), intraventricular haemorrage (IVH) and Periventricular leucomalacia (PVL) in 12 and Mixed pattern of injury in 7 babies. Findings among 9 expired babies were: 4 (44.4%) DG, 2 (22.2%) GMH+IVH and 3 (33.3%) mixed. There was neurological sequel in 13 babies (48.1%).  Babies with normal MRI initially had no sequel.Conclusion: Brain injury due to perinatal asphyxia follows several patterns according to gestational age and severity. Early and accurate recognition of these patterns with the help of MRI brain helps in managing the baby and predicting the prognosis.

Abstract Background The association between paroxysmal vertigo and right-to-left shunt (RLS) is rarely reported. We investigated the incidence and correlation of RLS in patients with different paroxysmal vertigo diseases. Methods This large observational study included patients with paroxysmal vertigo from seven different hospitals in China from 2017 to 2021 (NCT04939922). Migraine patients within the same period were included for comparison. Demographic data and medical history were collected, contrast transthoracic echocardiography (cTTE) was performed, and the clinical features, dizziness handicap inventory, and incidence of RLS in each group were recorded. Results This study used a consecutive sampling of 4536 patients from seven centres, and a total of 2751 patients were enrolled. The proportion of RLS in patients with migraine with aura (MA), migraine without aura (MoA), vestibular migraine (VM) with headache, VM without headache, and benign recurrent vertigo (BRV) was significantly higher than that in patients with benign paroxysmal positional vertigo (BPPV), Meniere’s disease (MD), and vestibular paroxysmia (VP) (P<0.05). There was no statistical difference between the frequency of RLS in patients with BRV and those with MoA (P=0.931), MA (P=0.997), VM with migrainous headache (P=0.787), and VM without migrainous headache (P=0.754). There was a positive correlation between the RLS grade and the dizziness handicap inventory scores of VM and BRV patients (P<0.01). Conclusions RLS was significantly associated with BRV and VM. RLS may be involved in the pathogeneses of BRV and VM and may serve as a reference index for the differential diagnosis of central and peripheral vertigo.

Abstract Purpose To investigate whether upright magnetic resonance imaging (MRI) has a role in defining thoracolumbar spine pathology in elite gymnastics. Methods A prospective cross-sectional observational study of National Senior and Junior Artistic gymnasts in three MRI positions (standard supine, upright flexed and extended positions). Two specialist musculoskeletal radiologists independently analysed images with neutral as a baseline with the effects of flexion and extension reported in line with Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. Results Forty (18 males) gymnasts aged 13–24 years with a mean (SD) of 32 (5.3) training hours per week consented with 75% showing MRI abnormalities. Degenerative disc disease (DDD) was evident in 55% participants with vertebral end plate (VEP) changes in 42.5%. Spondylolysis was present in 40% with an additional 17% showing chronic bilateral complete L5 pars defects. 23% participants demonstrated different MRI findings in upright flexion compared to neutral. Conclusion Findings suggest a high levels of MRI abnormalities in elite gymnastics including altered disc morphology and posterior element abnormalities. High prevalence of T11/12 DDD and VEP changes reflects the thoracolumbar junction being a transition zone. Upright MRI and varying spine position offer promise for enhanced visualisation of posterior element abnormalities.

The aim of this single-center observational study was to analyze the applicability of various imaging studies to the diagnosis and further evaluation of patients with chronic recurrent multifocal osteomyelitis (CRMO). The analysis included the data of 10 patients with CRMO treated between 2016 and 2021. The mean ages of the patients at the first manifestation of CRMO and ultimate diagnosis were 10 years and 7 months and 11 years and 10 months, respectively. Conventional radiography demonstrated focal loss of bone density in only 30% of the patients. Computed tomography showed disseminated foci with non-homogeneous osteolytic/osteosclerotic structure, with a massive loss of cortical layer and strong periosteal reaction. On magnetic resonance imaging (MRI), most patients presented with multifocal hypodense areas on T1-weighted images, with the enhancement of signal on T-weighted and STIR sequences. The duration of follow-up varied between 3 months and 3 years. In 40% of the patients, both clinical symptoms and the abnormalities seen on MRI resolved completely, whereas another 50% showed partial regression of clinical and radiological manifestations. MRI findings, co-existing with characteristic clinical manifestations, play a pivotal role in establishing the ultimate diagnosis of CRMO. MRI can also be used to monitor the outcomes of treatment in CRMO patients.
