Magic wand and the Enigma of the Sphinx

This paper presents an evaluation of the benefits and user acceptance of a multimodal interface in which the user interacts with a game-like interactive virtual reality application "The Enigma of the Sphinx". The interface consists of a large projection screen as the main display, a "magic wand", a stereo sound system and the user's voice for "casting spells". We present our conclusions concerning "friendliness" and sense of presence, based on observations of more than 150 users in a public even

Influence of surgically assisted rapid maxillary expansion on the interdental papilla height of maxillary central incisors

PURPOSE: To evaluate the influence of orthodontic treatment with surgically assisted rapid maxillary expansion (SARME) on the interdental papilla height of maxillary central incisors. METHODS: In this retrospective study, patients who completed orthodontic treatment including SARME at the Radboud University Medical Center Orthodontic Department before December 2019 were included. Frontal intraoral photographs taken before (T1) and after completion of treatment (T2) were examined to determine the papilla height between the maxillary central incisors using the Jemt classification. The difference between the Jemt classification at T1 and T2 (∆Jemt) was defined as the primary outcome variable. Secondary outcome variables were gender, age, treatment duration, type of expansion appliance, maximal central diastema during expansion, pretreatment overlapping between the central incisors, gingival biotype, crown morphology and the distance between the bone crest and incisal contact point. Kappa statistics and paired t‑tests were used to determine reliability of the measurements. Pearson's Χ(2) test and independent t‑tests were used to compare the variables between the groups of patients with and without papillary recession. Finally, multiple logistic regression analysis was performed. RESULTS: In all, 93 patients fulfilled the inclusion criteria and were included in the study. The Jemt score worsened for 30 patients (32%) between T1 and T2, indicating the occurrence of papillary recession. Incisal overlapping, crown morphology, small width to length ratio, increasing age and an increasing distance between crestal bone and the incisal contact point were factors associated with papillary recession. CONCLUSION: After orthodontic treatment including SARME, one third of patients exhibited recession of papilla height of the maxillary central incisors

Highlights du congrès 2022 de la Société suisse de médecine interne générale : partie 2 [Highlights of Swiss congress of internal general medicine: part 2]

From June 1 to 3, 2022, Lausanne held the spring congress of the Swiss Society of General Internal Medicine: "Changes and Opportunities". In this article, chief residents in internal medicine at CHUV summarize presentations they attended. Internal general medicine is established in french-speaking Switzerland as a transversal specialty, which is reflected in this synthesis with very varied subjects. In thromboembolic disease, the duration of anticoagulation is now based on risk of recurrence. The thrombotic microangiopathy benefit nowadays from targeted therapy which improve diseases' outcomes. The new anti-viral therapy against SARS-CoV-2 (nirmatrelvir/ritonavir) is associated with numerous drug interactions. Finally, professors from Switzerland and abroad give their advices for scientific writing and academic career initiation

Année 2022 mise en perspective par les internistes hospitaliers [The year 2022 placed in perspective by hospital internists]

According to PubMed statistics when writing this review, the year 2022 is expected to mark the first dip in the number of articles published in relation to the Covid-19 pandemic. This review, without any mention to Sars-CoV-2, highlight this transition and addresses many topics in internal medicine: gastroenterology, cardiology, endocrinology, respiratory medicine, infectious diseases and venous access. Each year, the chief residents of the internal medicine ward in Lausanne university hospital (CHUV) in Switzerland meet up to share their readings: here is a selection of ten articles that have caught our attention, summarized and commented for you, which should change our daily practice
