Pediatric cervical spine clearance after blunt trauma and negative CT: What is the role of MRI?

BACKGROUND AND PURPOSE: The cervical spine in children has marked anatomical and biomechanical differences compared to adults, leading to significantly different patterns and incidence of spinal injury, and consequently to different X-ray and computed tomography (CT) imaging recommendations. Magnetic resonance imaging (MRI) has been validated to clear cervical spine trauma in adults, but not in pediatric patients. We hypothesized that MRI findings have a low probability to change management in children with spine trauma and negative CT findings. MATERIALS AND METHODS: We reviewed records for admitted pediatric patients due to blunt trauma from January 2011 to May 2021, and identified 212 patients who underwent MRI within 3 days of a negative CT. Two neuroradiologists independently reviewed all CT and MRI images for the following categories: fracture, subluxation, spinal canal compromise, ligamentous injury, spinal canal hemorrhage, cord contusion and soft tissue hemorrhage. We identified follow-up MRI examinations as negative or positive for the above categories, and calculated the prevalence of each category as a percentage of cases with negative CT. We also evaluated whether negative and positive MRI groups differed significantly with respect to age and sex of the patients. RESULTS AND CONCLUSIONS: In our study of 212 children with cervical spine trauma and a negative CT, most follow-up MRI scans were found to be negative (79.9 %). Positive MRI findings consisted mainly of ligamentous sprain without disruption (15.1 %). Ligamentous disruption and epidural or soft tissue hemorrhage were found in 4.5 %, and focal cord contusion in 0.5 %. There was no statically significant difference between negative and positive MRI groups with respect to age (P = 0.45) and sex (P = 0.52). CONCLUSION: In our patient group with a negative CT, MRI did not significantly impact management nor contribute to cervical spine clearance in children.

Are Topical Corticoids Efficacious in Acute Irritant Dermatitis: The Evidence.

Topical corticosteroid therapies are widely utilized, despite the controversial results of corticoid therapy in irritant contact dermatitis as a local inflammatory reaction after repeated or single skin exposure to a chemical substance. Although corticoids may reduce the inflammatory response to the irritant, their antiproliferative effects may reduce skin barrier recovery while allowing further penetration of irritants if exposure continues. This overview reexamines the efficacy of corticosteroids in irritant contact dermatitis therapy, and with the minimal controlled experimental data currently available, notes the need for same-in this common clinical entity.

Sensitive Skin Syndrome: An Update.

Sensitive skin syndrome is a widely reported complaint but a diagnostic challenge because of its subjective symptoms and lack of clearly visible manifestations. Epidemiological studies have shown the prevalence of sensitive skin to be as high as 60-70% among women and 50-60% among men. Patients with this syndrome usually have unpleasant sensations when exposed to physical, thermal, or chemical stimuli that normally cause no provocation on healthy skin. Recent studies and newly accepted position papers have provided a more in-depth understanding and consensus of its underlying pathophysiology, associations, diagnosis, and treatment. Since no clinical studies have been conducted about specific treatment protocols, patients with this condition should be provided with personalized skin management. Given this updated knowledge, our review offers an approach to sensitive skin syndrome, with differential diagnoses, and interventions targeting its pathophysiology.
