Oral lichen planus and oral lichenoid lesions; a critical appraisal with emphasis on the diagnostic aspects
2009
Oral lichen planus (OLP) has a prevalence of approximately 1%. The etiopathogenesis is poorly understood. The annual malignant transformation is less than 0.5%. There are no effective means to either predict or to prevent such event. Oral lesions may occur that to some extent look like lichen planus but lacking the characteristic features of OLP, or that are indistinguishable from OLP clinically but having a distinct cause, e.g. amalgam restoration associated. Such lesions are referred to as oral lichenoid lesions (OLLs). The management of OLP and the various OLLs may be different. Therefore, accurate diagnosis should be aimed at.
Lichen Planus: A Muco-Cutaneous, Nails and Scalp Disorder – Cases Report
2019
Abstract Lichen planus is an autoimmune, itching disorder that involves T lymphocytes, which may interest the skin, mucous membranes and exoskeletons. The presence of lichen manifestations both at the skin, mucous membranes and at the level of the skin attachments (hair and nails) is rarely mentioned in the literature. Although lichen planus may have a self-limiting evolution, early treatment is important in shortening the evolution of the disease and in controlling the symptoms. The therapeutic effects of retinoids (immunomodulatory, anti-inflammatory, anti-proliferative effects) make them an appropriate choice in the treatment of lichen with (cutaneous-mucosal, nail and planopilaris lesio…
Chewing simulation: a way to understand the relationships between mastication, food breakdown and flavour release
2010
International audience; Understanding in-mouth mechanisms is necessary to understand flavour release and perception phenomena. To overcome the limitations of in-vivo flavour release measurements, we developed a chewing simulator that faithfully reproduced many mouth functions. Using brittle foods, we showed that in-vitro food breakdown was very comparable to that obtained in-vivo. We also studied on model cheeses in-vitro flavour release by connecting on-line the chewing simulator to APCI-MS. Preliminary results are discussed.
Skin surveillance attitudes and behaviors in relation to skin checks for early signs of skin cancer in a sample of secondary school students and teac…
2012
<p><strong>Background</strong>: Malignant melanoma (MM) can be readily treated in its earliest stages: survival rate, when detected early, is up to 95,0%. This justifies investigations on contributive factors and measures for precocious detection of skin tumors to improve early detection and to increase survival rates. The purpose of this survey was to collect information about knowledge, attitudes and behaviors on prevention in relation to skin checks for early signs of skin cancer on a sample of secondary school students and teachers.</p><p><strong>Methods</strong>: A sample of secondary school students and teachers from Palermo, was recruited usi…
Proximal versus distal contextual factors: which impact on meal pleasure and food intake in the elderly living in a nursing home?
2014
Poster présenté lors de la conférence; Introduction: Several authors pointed out the importance of meal context on food intake in nursing home. Some authors assessed the impact of context improvement on food intake in nursing home, but they assessed ‘holistic’ strategies by improving physical environment, increasing choice level, changing staff organization… (Abbott et al. 2013). Despite some of these interventions were effective, these strategies are costly and thus difficult to be implemented in nursing home. The aim of the present experiment was to assess the impact of single contextual factors, three proximal factors (food contextual factors) and three distal factors (non-food contextua…

Associations Between Sympathetic Nervous System Synchrony, Movement Synchrony, and Speech in Couple Therapy
2022
Background: Research on interpersonal synchrony has mostly focused on a single modality, and hence little is known about the connections between different types of social attunement. In this study, the relationship between sympathetic nervous system synchrony, movement synchrony, and the amount of speech were studied in couple therapy. Methods: Data comprised 12 couple therapy cases (24 clients and 10 therapists working in pairs as co-therapists). Synchrony in electrodermal activity, head and body movement, and the amount of speech and simultaneous speech during the sessions were analyzed in 12 sessions at the start of couple therapy (all 72 dyads) and eight sessions at the end of therapy (…
Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: A pooled analysis of 1018…
2018
Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean dia…
Convolutional neural networks in skin cancer detection using spatial and spectral domain
2019
Skin cancers are world wide deathly health problem, where significant life and cost savings could be achieved if detection of cancer can be done in early phase. Hypespectral imaging is prominent tool for non-invasive screening. In this study we compare how use of both spectral and spatial domain increase classification performance of convolutional neural networks. We compare five different neural network architectures for real patient data. Our models gain same or slightly better positive predictive value as clinicians. Towards more general and reliable model more data is needed and collection of training data should be systematic. peerReviewed
Näkeminen ja sokeus Jyrki Kiiskisen romaanissa Suomies
2010
Pro gradu työ käsittelee näkemistä ja sokeutta Jyrki Kiiskisen romaanissa Suomies. Työssä käydään läpi näköaistin aseman nousu länsimaisessa kulttuurissa lukutaidon lisääntyessä siirryttäessä keskiajalta renessanssiin. Ihmisen suhde itseensä ja miten hän näkee maailman, on liitoksissa tähän muutokseen. Tieteen nousu ohi kristinuskon maailman selittäjänä renessanssin aikana alkaneen tieteellisten läpimurtojen kautta näkyy myös siinä, miten ihminen on itseään peilistä katsonut. Työssä esitellään tutkimuksen kannalta oleelliset silmään, valoon, haukkaan ja peiliin liittyvät symbolit ja tarkastellaan romaanista löytyviä vastineita. Työssä tarkastellaan Jyrki Kiiskisen artikkelia ”Mitä sokeat nä…
