Survey Evaluating Sleep Education Catalyzed Change in Residency Training  [PDF]
Demetra S. Stamm, Sandra Taylor, Uyen Thao Nguyen, Kimberly Hardin
International Journal of Clinical Medicine (IJCM) , 2015, DOI: 10.4236/ijcm.2015.67058
Abstract:
Background: Despite the high prevalence and negative effects of sleep disorders, sleep issues often remain unexplored during medical encounters. Research has shown that primary care physicians regard their knowledge as inadequate. Objective: We investigated residents’ perceived adequacy of sleep education and level of competency in diagnosing and treating sleep disorders. Methods: A questionnaire via Survey Monkey was administered to senior residents in University of California, Davis (UCD) from family medicine, internal medicine, neurology, and psychiatry to assess perception of their knowledge and training of sleep disorders. Likert scale ratings were used, from 1 (not adequate/competent) to 5 (extremely adequate/competent). Non-parametric statistical methods were used to evaluate differences in survey responses among specialties and assess the correlation between survey responses. Results: Only 33 residents responded with a 29.5% response rate. Neurology residents routinely rotate with a sleep medicine attending and subsequently reported the highest self-competency, adequacy of training, hours of didactics received and frequency of asking patients about sleep. All other residents reported receiving insufficient sleep medicine education. The combined mean score was 1.5 across the specialties regarding adequacy of sleep education in their respective medical schools with 31.3% reporting no sleep medicine training. Conclusions: This study demonstrated that there is a perceived deficit in most residents’ training and competency regarding sleep disorders. These results prompted 2 of the 4 residency programs to change their educational structure with electives in clinical sleep medicine. We believe that this paper illuminates potential need for increasing sleep medicine education throughout various levels of training. Nationwide educational research is needed to promote ACGME to incorporate the fundamentals of sleep medicine into core curriculum. Current Knowledge/Study Rationale: There are no studies, to our knowledge, directly measuring residents’ perceived adequacy of sleep medicine education provided and their perceived level of competency in diagnosing and treating sleep disorders. The aim of this study was to evaluate both the amount of time and quality of sleep education provided to residents as insufficient knowledge in addressing sleep problems may reflect gaps in educational
End-Grafted Polymer Chains onto Inorganic Nano-Objects
Demetra S. Achilleos,Maria Vamvakaki
Materials , 2010, DOI: 10.3390/ma3031981
Abstract: Organic/inorganic nanohybrid materials have attracted particular scientific and technological interest because they combine the properties of the organic and the inorganic component. Inorganic nanoparticles exhibit interesting electrical, optical, magnetic and/or catalytic properties, which are related with their nano-scale dimensions. However, their high surface-to-volume ratio often induces agglomeration and leads to the loss of their attractive properties. Surface modification of the inorganic nano-objects with physically or chemically end-tethered polymer chains has been employed to overcome this problem. Covalent tethered polymer chains are realized by three different approaches: the “grafting to”, the “grafting from” and the “grafting through” method. This article reviews the synthesis of end-grafted polymer chains onto inorganic nanoparticles using “controlled/living” polymerization techniques, which allow control over the polymer characteristics and the grafting density of the end-tethered polymer chains.

Trials , 2013, DOI: 10.1186/1745-6215-14-20
Abstract: Background The aim of this randomised clinical trial was to assess the effect of early orthodontic treatment in contrast to normal growth effects for functional unilateral posterior crossbite in the late deciduous and early mixed dentition by means of three-dimensional digital model analysis. Methods This randomised clinical trial was assessed to analyse the orthodontic treatment effects for patients with functional unilateral posterior crossbite in the late deciduous and early mixed dentition using a two-step procedure: initial maxillary expansion followed by a U-bow activator therapy. In the treatment group 31 patients and in the control group 35 patients with a mean age of 7.3 years (SD 2.1) were monitored. The time between the initial assessment (T1) and the follow-up (T2) was one year. The orthodontic analysis was done by a three-dimensional digital model analysis. Using the ‘Digimodel’ software, the orthodontic measurements in the maxilla and mandible and for the midline deviation, the overjet and overbite were recorded. Results Significant differences between the control and the therapy group at T2 were detected for the anterior, median and posterior transversal dimensions of the maxilla, the palatal depth, the palatal base arch length, the maxillary arch length and inclination, the midline deviation, the overjet and the overbite. Conclusions Orthodontic treatment of a functional unilateral posterior crossbite with a bonded maxillary expansion device followed by U-bow activator therapy in the late deciduous and early mixed dentition is an effective therapeutic method, as evidenced by the results of this RCT. It leads to three-dimensional therapeutically induced maxillary growth effects. Dental occlusion is significantly improved, and the prognosis for normal craniofacial growth is enhanced.

Head & Face Medicine – a new journal for 'intra-interdisciplinary' science. Why? When? Where?
Thomas Stamm
Head & Face Medicine , 2005, DOI: 10.1186/1746-160x-1-1
Abstract: To be one of these instruments is the vision of Head & Face Medicine. To induce 'intra-interdisciplinary' thinking of scientists by bringing together the findings achieved by different researchers from various specialties, all exploring the same target structure – the human head and face. Head & Face Medicine's objective is to support scientists in gaining new insights from different views, to recognize patterns, to extract new thoughts, to recombine them and bring new visions to life.Evolving tools like the internet, e-publishing, Open Access and open peer review make Head & Face Medicine a cross between a traditional journal and a data stream which can be queried, analyzed and processed with the aim of increasing medical knowledge in the area of head and face medicine. These tools represent several advantages: fast publication, increase of a paper's scientific impact and ethical superiority.Head & Face Medicine looks forward to receiving your contributions.Hardly any region of the human body depends upon the synergism of a variety of medical disciplines to the same extent as the human head. To understand the complexity of the whole system 'head' it is necessary to reduce the system to its most discriminable elements and to explore their nature, because the elements realize certain functions in the whole. This philosophical tradition, the reduction principle, continues to be adhered to and developed in medical science. Attributable to this development is the ongoing fragmentation of medical disciplines into more and more sub-(sub-)specialties; or to put it more positively, one would argue: the opening of new fields.However, an adverse side effect of this progress is the separation of scientists working in different sub-specialties, resulting in a breakdown in communication. Intensive scientific debate is common within the fields but not across them. Specialization is necessary, but where in this process are the individuals who are able to recombine the pieces of kn

Editor's note: new facial nerve section and new editorial board member
Thomas Stamm
Head & Face Medicine , 2008, DOI: 10.1186/1746-160x-4-6
Abstract: Rainer Laskawi brings a wealth of experience to this new position. He experimentally studied the effects of peripheral nerve lesions (mainly facial nerve) on the central nervous system, especially on the supranuclear brain structures such as the motor cortex. His research group found fundamental short time changes in the functional cortical reorganization following different types of facial nerve lesions. Using glial cell markers, Laskawi and coworkers could demonstrate structural changes in later stages of cortical reorganization.Rainer Laskawi's research interests focus on clinical problems associated with the facial nerve and the salivary glands, and he also studied the clinical use of botulinum toxin in many indications concerning the head, face and neck region. His research group first described the clinical use and effectiveness of botulinum toxin in sweat glands to treat focal hyperhidrosis, a research initiative that was greatly acknowledged by the German ENT Society. Jointly with Peter Roggenk?mper (University of Bonn), he edited the volume Botulinumtoxin – Therapie im Kopf-Hals-Bereich.Rainer Laskawi is President of the Sir Charles Bell Society (SCBS), an international multi-disciplinary non-profit organization created at the VII International Facial Nerve Symposium in Cologne (1992), dedicated to collection, dissemination and interchange of ideas relating to the facial nerve. As the President of the SCBS, member of the Scientific Board of the German Dystonia Society, and Section Editor of Head & Face Medicine he holds key positions for encouraging and disseminating multi-disciplinary thinking among students, clinicians, and researchers with a scientific interest in the facial nerve.Head & Face Medicine is deeply grateful that Professor Laskawi will spend his valuable time to hold this new Section Editor position. His contribution will be important in helping shape the journal's course over the coming years.

Badminton-Smash Geschwindigkeitsmessung
Stamm Christoph
IMVS Fokus Report , 2012,
Abstract: Im Gegensatz zu internationalen Tennisturnieren, wo die Ballgeschwindigkeitsmessung bei Aufschl gen seit vielen Jahren zum Standard geh rt, gibt es bei entsprechenden Badmintonturnieren keine vergleichbaren Messungen. Solche Geschwindigkeitsmessungen sind prim r als Bereicherung für die Zuschauer gedacht, k nnen darüber hinaus aber auch den Spielern, Trainern und Ausrüstern wichtige Informationen liefern. Wir beschreiben in diesem Artikel unseren Ansatz zur Geschwindigkeitsmessung von Schmetterb llen in Badminton und berichten über erste Erfahrungen mit unserem Messsystem an den Badminton Swiss Open 2012 in Basel.
