A comparative study of bone remodeling molecules expression in different types of jaw ameloblastoma.

Background: Solid ameloblastoma demonstrates a more invasive behavior compared to unicystic. The follicular ameloblastoma is referred that may present a higher recurrence potential compared to the plexiform variant. In this study, the different ameloblastoma clinical types and histopathological variants were examined regarding the expression of bone remodeling-related molecules OPG, RANKL, and TRAIL.

Intra-osseous lesions in Greek children and adolescents. A study based on biopsy material over a 26-year period.

Objective: The purpose of this retrospective study was to investigate the spectrum of oral intra-osseous lesions in a Greek population, consisting of children and adolescents under 18 years of age.

Material And Methods: Data was obtained from the histopathological reports that accompanied biopsy request forms, which were retrieved from the files of the Oral Pathology Department, Faculty of Dentistry, University of Athens, during a 26-year period. A retrospective analysis with respect to patients' age and gender, frequency and location of the lesions was performed.

Elevated serum levels of the apoptosis related molecules TNF-alpha, Fas/Apo-1 and Bcl-2 in oral lichen planus.

Background: The serum circulatory levels of apoptosis related molecules measured in patients with oral lichen planus (OLP) and healthy individuals in order to investigate possible alterations associated with the clinical forms of OLP.

Methods: Serum levels of tumor necrosis factor (TNF)-alpha, soluble Fas (sFas) and Bcl-2 studied by enzyme-linked immunosorbent assay in whole blood samples in 13 OLP reticular, 13 OLP atrophic-erosive form patients and 26 healthy subjects.

Results: Significantly elevated levels of TNF-alpha and sFas detected in OLP patients as compared with controls.

Oral manifestations of papular-purpuric 'gloves and socks' syndrome due to parvovirus B19 infection: the first case presented in Greece and review of the literature.

Papular-purpuric 'gloves and socks' syndrome (PPGSS) is a novel, rare, self-limited dermatosis initially described in 1990. It is characterized by painful, pruritic edema and erythema, rapidly evolving to papular-purpuric lesions on the distal extremities, in a gloves-and-socks distribution, accompanied by fever and oral lesions such as petechiae, vesiculopustules and small erosions. Parvovirus B19 has been implicated in most cases as the etiological factor.

Short vs. long cotrimoxazole courses in eradicating bacteriuria in the elderly.

To test whether longer duration of treatment of asymptomatic bacteriuria in old age could improve the efficacy of cotrimoxazole therapy, three regimens were given to 75 ambulant bacteriuric residents of a retirement home, aged greater than or equal to 68 years. The groups and regimens were: A:23 subjects (160/800 mg b.i.
