To determine the efficacy of ketogenic diet (KD) therapy on adrenocorticotropic hormone- (ACTH) or corticosteroid-resistant infantile spasm (IS), and identify relevant associated factors. A prospective controlled study was undertaken at 10 tertiary children's medical centres in mainland China. Participants were non-randomly assigned to KD therapy or control (adjustment of antiepileptic drugs). The primary outcome was the reduction in spasms and remission of hypsarrhythmia at the 16th week, divided into Grade I (spasm-free for at least one week with hypsarrhythmia remission), Grade II (≥50% spasm reduction and/or hypsarrhythmia remission) and Grade III ( less then 50% spasm reduction with hypsarrhythmia). In total, 227 patients were recruited and assigned to the KD (135 patients) and control (92 patients) groups. The efficacy in the KD group was superior to that in the control group (Grade I 13.4% vs. 10.9%; Grade II 40.7% vs. 20.7%, p=0.025). Patients with a ketogenic ratio less then 31 had a higher rate of Grade I than those with ketogenic ratio ≥31 (66.7% vs. 33.3%, p=0.037). No significant correlation was found between the efficacy of KD and level of serum ketosis, aetiology of IS, or age. The efficacy of KD therapy was superior to adjustment of oral antiepileptic drugs in children with ACTH- or corticosteroid-resistant infantile spasms.Different surgical and non-surgical techniques have been developed in order to reduce the duration of orthodontic treatment. Regarding surgical techniques, corticotomies are widely used. The micro-osteoperforation technique (MOP), in addition to the piezocision technique, have been developed to provide minimally invasive surgery as an alternative to conventional corticotomies, without the elevation of a mucoperiosteal flap. Regarding non-surgical techniques, the approach is radically different in terms of physical stimuli or chemical techniques. Corticotomy and piezocision techniques have been found to be effective in accelerating orthodontic tooth movement, although the corticotomy technique presents a significant risk of postoperative treatment. These two techniques also offer the possibility of adding a bone graft using a tunneling surgical approach. Regarding non-surgical techniques, physical stimuli techniques such as with a laser are easy to perform, non-invasive and seem to be promising. However, their effectiveness has not yet been demonstrated, as is the case for chemical techniques. While at first glance these techniques are reassuringly non-invasive, do they not give the sensation of playing the sorcerer's apprentice ? Although surgical techniques seem to have demonstrated their significant efficacy in accelerating orthodontic tooth movement, non-surgical techniques do not yet provide a sufficient level of evidence and / or safety to be performed in our routine clinical practice as orthodontists. As these topics are innovative, new and future scientific evidence should be able to lead to the development of all these concepts.Digital technologies are gradually integrating our orthodontic practices and retainers, often less considered compared to active devices, are also benefiting. The author will give in this article a brief presentation of the various current possibilities offered by the use of digital tools for carrying out and monitoring fixed or removable retention methods. The digital workflow is perfectly suited to the production of modern and durable retainers, whether for fixed or removable devices, as well as their long-term monitoring. The objective is not to decide on the superiority of one system over another, but to expose all the possibilities for adapting the digital tool to the orthodontist's method of retention. The benefit of using digital technology is saving time and improving performance, minimizing unnecessary manipulation and improving device precision. Digital technology provides all the elements necessary to achieve new generation retainers both more simply, and for them to be more precise and more durable. These technologies are in constant progress and we can still consider improvements in the near future as software and hardware developments progress.
Squamous cell carcinoma (SCC) represents the most common histotype of all head and neck malignancies and includes oropharyngeal squamous cell carcinoma (OSCC), a tumor associated with different clinical outcomes and linked to human papilloma virus (HPV) status. Translational research has few available
models with which to study the different pathophysiological behavior of OSCCs. The present study proposes a 3-dimensional (3D) biomimetic collagen-based scaffold to mimic the tumor microenvironment and the crosstalk between the extracellular matrix (ECM) and cancer cells.

We compared the phenotypic and genetic features of HPV-positive and HPV-negative OSCC cell lines cultured on common monolayer supports and on scaffolds. We also explored cancer cell adaptation to the 3D microenvironment and its impact on the efficacy of drugs tested on cell lines and primary cultures.

HPV-positive and HPV-negative cell lines were successfully grown in the 3D model and displayed different collagen fiber organization. Thcture appears capable of inducing drug-resistance processes that can be studied to better our understanding of the different clinical outcomes of HPV-positive and HPV-negative patients with OSCCs.The active participation of skeletal muscles is a unique characteristic of exertional heat stroke. Nevertheless, the only well-documented link between skeletal muscle activities and exertional heat stroke pathophysiology is the extensive muscle damage (e. g., rhabdomyolysis) and subsequent leakage of intramuscular content into the circulation of exertional heat stroke victims. Here, we will present and discuss rarely explored roles of skeletal muscles in the context of exertional heat stroke pathophysiology and recovery. This includes an overview of heat production that contributes to severe hyperthermia and the synthesis and secretion of bioactive molecules, such as cytokines, chemokines and acute phase proteins. These molecules can alter the overall inflammatory status from pro- to anti-inflammatory, affecting other organ systems and influencing recovery. LY2157299 manufacturer The activation of innate immunity can determine whether a victim is ready to return to physical activity or experiences a prolonged convalescence. We also provide a brief discussion on whether heat acclimation can shift skeletal muscle secretory phenotype to prevent or aid recovery from exertional heat stroke.
