Morphea “en coup de sabre”: an unusual oral presentation
2017
Morphea, or localized scleroderma, is an inflammatory disease that leads to sclerosis of the skin and underlying tissues due to excessive collagen deposition. Oral involvement is unusual and it may produce white linear fibrotic areas with a scar-like appearance, atrophy of tongue papillae, gingival recession and alveolar bone resorption. We report a case of a 13-year-old girl who consulted for progressive recession on the attached gingiva of her upper left incisors. She also presented a hypopigmented line on the left side skin of her upper lip, which continued through the vermilion and the lip mucosa, including the gingiva of the affected teeth. Clinical examination, blood tests, computeriz…
Relationship between the seed rain and the establishment of vegetation in two areas abandoned after peat harvesting
1987
In this study the number and species composition of diaspores dispersing into two newly abandoned peat harvesting areas in Finland were investigated. In an area abandoned six years earlier a total of 2978 living seeds m−2, representing 18 species, was captured by using water-filled traps during two summers. In a one-year-old succession area the total number of living seeds m−2 was 2241, representing 16 plant species. The soil seed banks were found to be empty of viable seeds. In neither area there appeared to be any relation between number of dispersing seeds and of plant individuals of the same species in the pioneer vegetation. It is suggested that unfavourable conditions on the soil surf…
Methanotrophy induces nitrogen fixation during peatland development
2013
Significance In peatlands, the external sources of nitrogen are mainly atmospheric, but the atmospheric nitrogen deposition alone cannot explain the long-term annual nitrogen accumulation rates to these ecosystems. Because of methodological problems, methane-induced fixation of atmospheric dinitrogen gas has been previously overlooked as an additional nitrogen input mechanism. We found that the activity of methane-oxidizing bacteria provides not only carbon but also nitrogen to peat mosses and, thus, contributes to carbon and nitrogen accumulation in peatlands, which store approximately one-third of the global soil carbon pool. Our results imply that nitrogen fixation in wetlands may be str…
Impact of Global Economic Crisis on the European Welfare States
2013
The global economic crisis and the subsequent weaker growth are putting under pressure welfare states in the EU. This paper aims at discussing the effects of the crisis at the social level and at identifying whether the classic European welfare state models (Nordic, Continental, Anglo-Saxon and Mediterranean) are still valid in today’s economy. An answer will be tried using the mathematical tool of principal components analysis. The results will be observed in graphs where the states taken into consideration respect the classical welfare models or they regroup themselves into new circumstances’ adapted models. Even though the classical welfare models are generally still checked up with the …
Oral hygiene and periodontal health status among khat chewers. A case-control study
2016
Background Habitual khat chewing is a widespread male habit in Southern Arabia and East Africa. The aim of this study was to assess the effect of Khat chewing on oral hygiene and periodontal health status among Yemeni male khat chewers. Material and Methods This case- control study included 310 khat chewers, aged 20-65 years, and 72 age- and gender- matched non-chewers as controls. Periodontal examination included recording of dental plaque index (PI), gingival index (GI), probing pocket depth (PPD), attachment level (AL) and gingival recession (GR). Demographic data, oral hygiene practices, and duration, frequency and site of khat chewing were obtained using questionnaires. SPSS was used f…
Etiology and Prevalence of Gingival Recession
2018
Gingival recession is a highly prevalent problem affecting individuals of all ages worldwide. Before considering any therapeutic strategies for gingival recession defects, it is important to identify the underlying etiological factors that contributed to the development of the clinical condition. The main etiological factors for gingival recession are plaque-induced periodontal inflammation and mechanical trauma caused by improper toothbrushing habits. Several other predisposing and precipitating factors have also been implicated in the etiology of gingival recession. The aim of this chapter is to summarize the different etiological factors contributing to the development of gingival recess…
Healing of intrabony defects following surgical treatment with or without an Er:YAG laser. A pilot study
2004
Aim: The aim of this controlled, parallel design clinical study was to compare the healing of intrabony periodontal defects following treatment with access flap surgery with and without debridement with an Er:YAG laser. Methods: Twenty-three patients each of whom exhibited one deep intrabony defect were randomly treated with either access flap surgery followed by root surface and defect debridement using an Er:YAG laser (KEY3®) (160 mJ, 10 Hz) (test), or with access flap surgery followed by root surface and defect debridement using hand and ultrasonic instruments (control). The following clinical parameters were recorded at baseline and at 6 months: plaque index; gingival index; bleeding on…

Versos para Felipe V: teatro y propaganda borbónica en Peñíscola durante la Guerra de Sucesión Española
2019
El propòsit del present treball és analitzar el contingut propagandístic de l’obra de teatre amb el títol de Comedia famosa en que se representa el asedio o sitio de Peñíscola, que versa sobre el cerco a eixa fortalesa valenciana (desembre de 1705 a maig de 1707) durant la Guerra de Successió. Como esdevé en altres textos propis de la publicística borbònica, la finalitat adoctrinadora de l’obra es concentra en la legitimació de Felipe V mitjançant la identificació de la seua causa con la de la Providència, així com en la crítica a l’arxiduc Carles i els seus aliats, en un context de pugna por l’opinió entre los dos bàndols. Al mateix temps, la peça va servir de pretext per la construcció d’…
