Children are at risk for sustaining hand burns due to their innate curiosity, slow withdrawal reflexes, and thin palmar epidermis. We sought to summarize our recent experience managing pediatric hand burns, focusing on injuries that required surgical management. This was a retrospective review of children with burn-injured hands managed at a quaternary referral children's hospital between 2016 and 2020. Demographics and mechanisms of injury were collected for all patients. Initial management of all wounds included pain control, deflation of blisters, and mechanical debridement. Wounds were then dressed, and a plaster-backed soft cast was applied for positioning if the swelling was controlled. Wounds were reassessed in 4-7 days, at which time a nonadherent dressing with antifungal ointment or a bismuth dressing was applied to partial-thickness wounds, vs an active silver dressing for deep partial-thickness burns. For patients who underwent split-thickness or full-thickness skin grafting, additional wound care, operative, and short-term outcomes data were collected. A total of 3715 children were seen for burn injuries during the study period, of which 2100 (56.5%) were seen for hand burns. In total, 123 (5.8%) required a skin graft an average of 11.7 days from the date of their burn injury. Surgical complications were minimal with 5 (4.1%) incomplete graft takes, though none required reoperation, and 1 (0.8%) experiencing a postoperative wound infection. Pediatric hand burns are common. A multidisciplinary treatment approach, including standardized wound care and adept therapeutic interventions, will lead to spontaneous healing in approximately 95% of patients.

Electrodermal activity (EDA) usually relates to variations in the electrical properties of palmar or plantar skin sites. EDA responses, namely skin conductance responses (SCRs), skin potential responses (SPRs) and skin susceptance responses (SSRs) are shown to be sensitive indexes of sympathetic nervous system activation and are studied in many research projects. However, the association between EDA responses and the five basic human senses has not been investigated yet. Our study aimed to explore the relationship between the three EDA responses (SCRs, SSRs and SPRs) and the five basic human senses. These three EDA responses were measured simultaneously at the same skin site on each of the 38 volunteers. The tested five senses were sight, hearing, touch, taste and smell. The results showed that the different tested senses led to different degrees of EDA responses due to activation of the sympathetic nervous system and corresponding secretion of sweat. Although a controlled study on the degree of EDA as a function of the strength of each stimulus was not performed, we noted that the largest EDA responses were typically associated with the smell sense test. We conclude that EDA responses could be utilized as measures for examining the sensitivity of the human senses. Hence, EDA devices may have important roles in sensory systems for future clinical applications.

Neonatal resveratrol treatment in cerebral palsy model recovers neurodevelopment impairments by restoring the skeletal muscle morphology and decreases microglial activation in the cerebellum.
Cerebral Palsy (CP) is the main motor disorder in childhood resulting from damage to the developing brain. Treatment perspectives are required to reverse the primary damage caused by the early insult and consequently to recover motor skills. Resveratrol has been shown to act as neuroprotection with benefits to skeletal muscle. This study aimed to investigate the effects of neonatal resveratrol treatment on neurodevelopment, skeletal muscle morphology, and cerebellar damage in CP model. Wistar rat pups were allocated to four experimental groups (n = 15/group) according CP model and treatment: Control+Saline (CS), Control+Resveratrol (CR), CP + Saline (CPS), and CP + Resveratrol (CPR). CP model associated anoxia and sensorimotor restriction. CP group showed delay in the disappearance of the palmar grasp reflex (p < 0.0001) and delay in the appearance of reflexes of negative geotaxis (p = 0.01), and free-fall righting (p < 0.0001), reduced locomotor activity and motor coordination (p < 0.05) than CS group. These motor skills impairments were associated with a reduction in muscle weight (p < 0.001) and area and perimeter of soleus end extensor digitorum longus muscle fibers (p < 0.0001), changes in muscle fibers typing pattern (p < 0.05), and the cerebellum showed signs of neuroinflammation due to elevated density and percentage of activated microglia in the CPS group compared to CS group (p < 0.05). CP animals treated with resveratrol showed anticipation of the appearance of negative geotaxis and free-fall righting reflexes (p < 0.01), increased locomotor activity (p < 0.05), recovery muscle fiber types pattern (p < 0.05), and reversal of the increase in density and the percentage of activated microglia in the cerebellum (p < 0.01). Thus, we conclude that neonatal treatment with resveratrol can contribute to the recovery of the delay neurodevelopment resulting from experimental CP due to its action in restoring the skeletal muscle morphology and reducing neuroinflammation from cerebellum.
