RESUMO
OBJECTIVE: The objective of this study was to evaluate the efffectiveness of a titanium vertebral augmentation device (SpineJack system) in terms of back pain, radiological outcomes, and economic burden compared with nonsurgical management (NSM) (bracing) for the treatment of vertebral compression fractures. Complications were also evaluated for both treatment methods. METHODS: A prospective multicenter randomized study was performed at 9 French sites. Patients (n = 100) with acute traumatic Magerl type A1 and A3.1 vertebral fractures were enrolled and randomized to treatment with the SpineJack system or NSM consisting of bracing and administration of pain medication. Participants were monitored at admission, during the procedure, and at 1, 12, and 24 months after treatment initiation. Primary outcomes included visual analog scale back pain score, and secondary outcomes included disability (Oswestry Disability Index [ODI] score), health-related quality of life (EQ-5D score), radiological measures (vertebral kyphosis angle [VKA] and regional traumatic angulation [RTA]), and economic outcomes (costs, procedures, hours of help, and time to return to work). RESULTS: Ninety-five patients were included in the analysis, with 48 in the SpineJack group and 47 in the NSM group. Back pain improved significantly for all participants with no significant differences between groups. ODI and EQ-5D scores improved significantly between baseline and follow-up (1, 12, and 24 months) for all participants, with the SpineJack group showing a larger improvement than the NSM group between baseline and 1 month. VKA was significantly lower (p < 0.001) (i.e., better) in the SpineJack group than in the NSM group at 1, 12, and 24 months of follow-up. There was no significant change over time in RTA for the SpineJack group, but the NSM group showed a significant worsening in RTA over time. SpineJack treatment was associated with higher costs than NSM but involved a shorter hospital stay, fewer medical visits, and fewer hours of nursing care. Time to return to work was significantly shorter for the SpineJack group than for the NSM group. There were no significant differences in complications between the two treatments. CONCLUSIONS: Overall, there was no statistical difference in the primary outcomes between the SpineJack treatment group and the NSM group. In terms of secondary outcomes, SpineJack treatment was associated with better radiological outcomes, shorter hospital stays, faster return to work, and fewer hours of nursing care.

INTRODUCTION: Software to predict the impact of aging on physical appearance is increasingly popular. But it does not consider the complex interplay of factors that contribute to skin aging. OBJECTIVES: To predict the +15-year progression of clinical signs of skin aging by developing Causal Bayesian Belief Networks (CBBNs) using expert knowledge from dermatologists. MATERIAL AND METHODS: Structures and conditional probability distributions were elicited worldwide from dermatologists with experience of at least 15 years in aesthetics. CBBN models were built for all phototypes and for ages ranging from 18 to 65 years, focusing on wrinkles, pigmentary heterogeneity and facial ptosis. Models were also evaluated by a group of independent dermatologists ensuring the quality of prediction of the cumulative effects of extrinsic and intrinsic skin aging factors, especially the distribution of scores for clinical signs 15 years after the initial assessment. RESULTS: For easiness, only models on African skins are presented in this paper. The forehead wrinkle evolution model has been detailed. Specific atlas and extrinsic factors of facial aging were used for this skin type. But the prediction method has been validated for all phototypes, and for all clinical signs of facial aging. CONCLUSION: This method proposes a skin aging model that predicts the aging process for each clinical sign, considering endogenous and exogenous factors. It simulates aging curves according to lifestyle. It can be used as a preventive tool and could be coupled with a generative AI algorithm to visualize aging and, potentially, other skin conditions, using appropriate images.

Kimura disease (KD) is a rare, chronic angiolymphoproliferative inflammatory disease appearing to be mostly restricted to the skin and soft tissue. Cutaneous involvement of KD includes head and/or neck nodules showing suggestive histological features, frequently associated with an atopic dermatitis-like or prurigo-like presentation. KD is challenging to treat, with high rate of recurrence using current therapeutic strategies. Evidence for involvement of a T-helper type 2 (Th2) immune response in KD pathogenesis has been found in previous studies. Consequently, this study aimed to determine the efficacy and safety of dupilumab, a human monoclonal antibody that inhibits signalling of key Th2 cytokines, interleukin (IL)-4 and IL-13, within a single-centre cohort of patients with cutaneous KD. Two adults with a diagnosis of refractory (failure of at least one treatment line) cutaneous-restricted KD based on clinical, biological, histological, molecular and imaging findings received dupilumab for KD, and showed dramatic response with a good safety profile.
