1/2. Severe periodontitis in a 5-year-old girl with hyperimmunoglobulin E syndrome.The hyperimmunoglobulin E syndrome (HIES) is a multisystem disorder that affects the: (1) dentition; (2) skeleton; (3) connective tissues; and (4) immune system. Little is known about periodontal manifestations of the syndrome. The purpose of this report was to describe a 5-year-old girl with suspected autosomal-recessive HIES syndrome who revealed profusely bleeding and painful gingiva and generalized aggressive periodontitis. A polymerase chain reaction (PCR)-based microbiological examination detected porphyromonas gingivalis, Tannerella forsythia, prevotella nigrescens, treponema denticola, eikenella corrodens, and campylobacter rectus in the deep periodontitis lesions. The extraction of all deciduous teeth due to a poor prognosis and risk of systemic infection led to resolution of the oral inflammation. Long-term follow-up is required to determine the periodontal prognosis of the erupting permanent teeth.- - - - - - - - - - ranking = 1keywords = periodontitis (Clic here for more details about this article) |
2/2. Ligneous periodontitis and ehlers-danlos syndrome.BACKGROUND: Generalized membranous gingival enlargement due to an accumulation of fibrin deposits associated with severe alveolar bone loss (ligneous periodontitis) is a rare condition, and plasminogen deficiency seems to play a central role in its pathogenesis. However, this condition has not been described in association with syndromes. This article reports a case of ligneous periodontitis in a boy with the classic type of ehlers-danlos syndrome (EDS). methods: A 12-year-old white male presented with generalized gingival overgrowth and severe alveolar bone loss. A physical examination revealed clinical signs of EDS (velvety skin with mild hyperextensibility, marked hypermobility of the limb joints, atrophic scars on his knees, and easy bruising), which is associated with a positive family history for joint hypermobility. A biopsy of gingival tissues was submitted for routine histology, hematoxylin and eosin (H&E), and direct immunofluorescence (antifibrinogen). An evaluation of plasminogen activity was also performed. RESULTS: Histopathology revealed chronic periodontitis with fibrinoid material deposition, and direct immunofluorescence proved to be positive for fibrin. Functional plasminogen was reduced. A conclusive diagnosis of ligneous periodontitis due to plasminogen deficiency associated with the classic type of EDS was rendered. CONCLUSIONS: ehlers-danlos syndrome can be associated with ligneous periodontitis. In the present case, the histologic examination represented an important tool in the differential diagnosis, because it ruled out EDS type VIII as the associated systemic factor to periodontal breakdown.- - - - - - - - - - ranking = 1.5keywords = periodontitis (Clic here for more details about this article) |
