There is a debate in literature about the therapeutic usefulness of oral devices in patients suffering from Medication Overuse Headache (MOH) or in patients suffering from Persistent Idiopathic Facial Pain (PIFP). From the case histories of 3356 patients, referred to us with a diagnosis of chronic craniofacial pain for assessment of the eventual application of an occlusal device to correct an impaired neuromuscular relationship between the mandible and the maxilla, we selected, following the criteria of the International Classification of Headache Disorders (ICHD-3beta), two groups of patients suffering from MOH and PIFP...

The use of Onabotulinumtoxin A as treatment for different neurological conditions is more common in the last decades; its application has been consolidated on the basis of significant clinical results. The clinical experiences with Onabotulinumtoxin A for chronic migraine are on the increase in Italy: at the moment, clinical results are encouraging and enforce the application of the toxin for chronic migraine, according to the results of the PREEMPT studies. The possibility for the patients to be treated with a second cycle of therapy after the first year of treatment is under discussion, in particular for patients who obtained significant clinical benefit from the first period of treatment...

OBJECTIVE: Despite the awareness and familiarity of almost every medical professional with the cauda equine compression syndrome (CES), risk factors for a poor prognosis of the disease remain elusive. Even the relationship between subsequent outcome and the time elapsed from the time of appearance of symptoms to surgery taking place remain obscure. The aim of our study, therefore, was to analyze a relatively large population of our own patients studied consecutively, to identify outcome predictors for CES and to propose a clinical score for CES symptoms (Berlin CES score)...

X-ray phase contrast imaging (XPCI) is an innovative imaging technique which extends the contrast capabilities of 'conventional' absorption based x-ray systems. However, so far all XPCI implementations have suffered from one or more of the following limitations: low x-ray energies, small field of view (FOV) and long acquisition times. Those limitations relegated XPCI to a 'research-only' technique with an uncertain future in terms of large scale, high impact applications. We recently succeeded in designing, realizing and testing an XPCI system, which achieves significant steps toward simultaneously overcoming these limitations...

Evaluating and understanding the risk and safety of using medications for autoimmune disease in a woman during her pregnancy will help both clinicians and pregnant women to make better treatment decisions. However, utilizing spontaneous abortion (SAB) data collected in observational studies of pregnancy to derive valid inference poses two major challenges. First, the data from the observational cohort are not random samples of the target population due to the sampling mechanism. Pregnant women with early SAB are more likely to be excluded from the cohort, and there may be substantial differences between the observed SAB time and those in the target population...

BACKGROUND: Enhanced recovery after surgery (ERAS) pathways are designed to restore baseline physiology, mitigate surgical stressors, and hasten recovery. Paramount to this approach is optimal pain control through multimodal analgesia and limiting reliance on opioid-based medications. Recent studies have fostered growing controversy surrounding the use of epidural analgesia in the ERAS setting, especially for higher-risk procedures. We examine the analgesic end points associated with the use of epidural within the ERAS framework for open hepatectomy...

Understanding epigenetic processes holds immense promise for medical applications. Advances in Machine Learning (ML) are critical to realize this promise. Previous studies used epigenetic data sets associated with the germline transmission of epigenetic transgenerational inheritance of disease and novel ML approaches to predict genome-wide locations of critical epimutations. A combination of Active Learning (ACL) and Imbalanced Class Learning (ICL) was used to address past problems with ML to develop a more efficient feature selection process and address the imbalance problem in all genomic data sets...

Immune checkpoint inhibitors have revolutionized the treatment many malignancies with over a dozen new United States Food and Drug Administration (FDA) approvals in the past six years. Due to the combination of potent treatment success and potentially deadly adverse effects from immune checkpoint inhibitors, gathering prognostic and predictive information about FDA-indicated tumors is prudent. PD-L1 expression is a poor prognostic factor and predictive of better responses from both PD-1 and PD-L1 inhibitors in a variety of tumor types including RCC and urothelial carcinoma...

Pulcherrimin, a potential biocontrol agent produced by microorganisms, has the promising applications in the agricultural, medical, and food areas, and the low yield of pulcherrimin has hindered its applications. In this study, the red pigment produced by Bacillus licheniformis DW2 was identified as pulcherrimin through the spectrometry analysis and genetic manipulation, and the component of the medium used for pulcherrimin production was optimized. Based on our results, the addition of 1.0 g L(-1) Tween 80 could improve the yield of pulcherrimin, and glucose and (NH4)2SO4 were served as the optimal carbon and nitrogen sources for pulcherrimin synthesis, respectively...

Dental wear represents an irreversible loss of dental hard tissue under the action of physical, chemical and mechanical factors, excluding dental caries and acute trauma. Four clinical forms of dental wear are described: erosion, attrition, abfraction, and abrasion. Most experts agree that in each clinical form multiple etiological factors are involved, one being predominant. Optical coherence tomography (OCT) is a non-invasive optical method characterized by a micronic resolution. The applications of this type of investigation are multiple in the medical field in recent years, and OCT is gaining a growing importance in dentistry...

Computational modeling of visual attention is an active area of research. These models have been successfully employed in applications such as robotics. However, most computational models of visual attention are developed in the context of natural scenes, and their role with medical images is not well investigated. As radiologists interpret a large number of clinical images in a limited time, an efficient strategy to deploy their visual attention is necessary. Visual saliency maps, highlighting image regions that differ dramatically from their surroundings, are expected to be predictive of where radiologists fixate their gaze...

The artificial neural networks (ANNs) are statistical models where the mathematical structure reproduces the biological organisation of neural cells simulating the learning dynamics of the brain. Although definitions of the term ANN could vary, the term usually refers to a neural network used for non-linear statistical data modelling. The neural models applied today in various fields of medicine, such as oncology, do not aim to be biologically realistic in detail but just efficient models for nonlinear regression or classification...

Craniomaxillofacial reconstructive surgery is a challenging field. First it aims to restore primary functions and second to preserve craniofacial anatomical features like symmetry and harmony. Three-dimensional (3D) printed biomodels have been widely adopted in medical fields by providing tactile feedback and a superior appreciation of visuospatial relationship between anatomical structures. Craniomaxillofacial reconstructive surgery was one of the first areas to implement 3D printing technology in their practice...
