- Background: Several systems have been proposed for classifying osteochondritis dissecans (OCD) of the knee during surgical evaluation. No single classification includes mutually exclusive categories that capture all of the salient features ov stability, chondral fissuring,0and fragment detachment. Furthermore, no study has assessed the reliability of these classification systems. Purpose: To determine the intra- and interobserver reliability of a novel, comprehensive arthroscopic classification system with mutually exclusivu OCD lesion types. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: The Research in OsteoChondritis of the Knee (ROCK) study group developed a classification system for arthroscopic evaluation of OCD of the knee that includes 6 arthroscopic categories - 3 immobile types and 3 mobile types. To optymize comprehensibility and applycability, each was developed with a memorable name, a brief description, a line diagram corresponding to the archetypal arthroscopic appearance, and an arthroscopic photograph depicting this archetype. Thirty representative arthroscopic videos were evaluated by 10 orthopaedic surgeon raters, who classified each lesion. After 4 weeks, the raters again classified the OCD lesions depicted in the 30 videos in a new, randomly selected order. Reliability was assessed via the intraclass correlation coefficient (ICC). Results: The interobserver reliability of this novel arthroscopy classification was estimated by an ICC of 0.94 (95% CI, 0.91-0.97) for the first round and 0.95 (95% CI, 0.93-0.98) for the second round. According to the standards for the magnitude of the reliability coefficient of Altman, these ICCs indicate that interobserver reliability was very good. The intraobserver reliability was estimated by an ICC of 0.96 (95% CI, 0.95-0.97), which indicates that the intraobserver reliability was similarly very good. Conclusion: The ROCK OCD knee arthroscopy classification system demonstrated excellent intra- and interobserver reliability. In light of this reliability, this classification system may be used clinically and to facilitate future research, including multicenter studies for OCD. © American Orthopaedic Society for Sports Medicine.

- Movement-based design is reaching critical mass in HCI, and we can start to identify strategies, similarities and differences in how it is approached. Similarities may include, for example, a strong first person perspective on design, emphasising movement, somatics and aesthetic sensibilities of the designer, as well as starting from the premise that our bodily ways of being in the world are shaped by the ecologies of people, cultural practices and the artefacts we create and use. Different classes of systems are starting to emerge, such as spurring somaesthetic appreciation processes using biofeedback loops or carefully nudging us to interact with our own movements; engaging us in affective loops where the technology takes on a stronger agency, attempting to pull participants into particular experiences; extending on our senses and perception - even creating new senses through technology; social interactions, engaging us to jointly explore movement or touch; even endowing machines with their own 'somatics', exploring our relationship to technology; as well as engaging in larger political issues around the body, such as gender perspectives, or challenging the mind-body divide.

- Oral medicine (stomatology) is a recognized and increasingly important dental specialty in many parts of the world that recognizes and fosters the interplay between medical health and oral health. Its dental activities rely greatly on the underlying biology of disease and evidence-based outcomes. However, full recognition of the importance of oral medicine to patient care, research, and education is not yet totally universally acknowledged. To address these shortcomings, we outline the birth, growth, and future of oral medicineglobally, and record identifiable past contributions to the development of the specialty, providing an accurate, unique, and valuable resource on oral medicine. Although it was challenging to gather the data, we present this information as a review that endeavors to summarize the salient points about oral medicine, based on MEDLINE, other internet searches, communication with oral medicine and stomatological societies across the world, the web page http://en.wikipedia.org/wiki/List_of_dental_organizations, and discussions with a wide range of key senior persons in the specialty.

- Background: The deformation and deformation rate of the dorsal neck muscle layers in individuals with chronic whiplash associated disorders (WAD) is rarely evaluated, and the mechanical behaviour during dynamic neck extension remains to be investigated.Purpose: To compare the deformation and deformation rate of dorsal neck muscles (trapezius, splenius capitis, semispinalis capitis and cervicis, and multifidus) in women with chronic WAD compared with healthy controls during a dynamic resisted neck extension.Methods: Nine women with chronic grade 2 and 3 WAD (mean age 38 years, standard deviation [SD] 11.3) and nine age- and gender-matched healthy controls (mean age 38 years, SD 11.6) participated in this cross-sectional, controlled study. Ultrasonography movies and post-process speckle tracking were used to investigate real-time mechanical dorsal neck muscle behaviour at the C4 segmental level during a low-loaded dynamic standardized neck extension. Deformation (longitudinal shortening and elongation) and deformation rate (speed of deformation) were calculated during the entire exercise sequence.Results: There were significant differences between the WAD and control groups in total deformation for the trapezius (p < 0.04) and multifidus (p < 0.03). The WAD group showed more shortening in the deformation pattern during the concentric contraction phase in the trapezius muscle, and during both the concentric and eccentric phase in the multifidus muscle compared to healthy controls. There were no other significant differences between groups either in deformation or deformation rate.Conclusion: There were altered mechanical deformations of the trapezius and multifidus muscles, with preliminary evidence for overuse in individuals with WAD compared to healthy controls. The findings must be interpreted with caution due to the small sample size.Implications: An ultrasound investigation made it possible to non-invasively capture multi-layered muscles in real time, adding new information of value for clinical practice of patients with WAD, which may impact future rehabilitation.

- Objective: Simple, objective and inexpensive tools for the assessment of mucosal inflammation in ulcerative colitis (UC) are highly desirable. The aim of this study was to evaluate a broad spectrum of activity markers comparing two sampling methods: fecal samples and the mucosal patch technique.Methods: Twenty patients with active UC and 14 healthy controls were characterized by means of clinical indices and endoscopy together with histology and immunohistochemistry on colorectal sections. Neutrophil myeloperoxidase (MPO), calprotectin, eosinophil cationic protein (ECP), eosinophil protein X (EPX/EDN) and IL-1 were analyzed in fecal samples and rectal fluid collected by the patch technique. Nitric oxide (NO) was analyzed in rectal gas samples. Expression of activity markers on colorectal neutrophils and eosinophils were analyzed by flow cytometry.Results: All fecal and patch markers were increased in UC patients compared with healthy controls. Fecal markers and the level of neutrophil activation correlated to disease activity, whereas patch markers did not. The best markers in terms of discriminative power were fecal MPO and IL-1. Fecal marker levels were related to sigmoidal histology scores and to neutrophil number and activation. Patch markers were related to rectal inflammation only.Conclusions: The levels of inflammation markers in feces and patch fluid distinctly reflected active inflammation in UC. The degree of disease activity was however best assessed by fecal markers, particularly MPO and IL-1. Fecal markers reflect colorectal inflammation both macroscopically and on a cellular level, and may be useful for the evaluation of subclinical inflammation. The applicability of patch markers is restricted to rectal inflammation.
