Angiosarcoma of the nasal septum mimicking reticulohistiocytoma.

Angiosarcomas are rare, aggressive tumors of endothelial cells with a high degree of invasiveness and poor survival. Although they arise in the face and scalp of elderly people, the nose represents a rare location with few reports in the literature. Nasal angiosarcoma resembling benign lesion morphologically has been described, but there is no report of angiosarcoma mimicking benign lesion histologically.

Congenital infiltrating lipomatosis of the face with associated involvement of the TMJ structures. Case report and review of the literature.

We report a case of congenital infiltrating lipomatosis of the face (CILF) with right TMJ ankylosis causing asymmetry and reduced mouth opening. The management involved soft tissue debulking combined with a right TMJ arthroplasty and is explained in detail. A review of the relevant literature revealed the rarity of this condition.

Mediterranean diet and upper aerodigestive tract cancer: the Greek segment of the Alcohol-Related Cancers and Genetic Susceptibility in Europe study.

Several dietary factors have been associated with the occurrence of cancers of the oral cavity and oropharynx, larynx and oesophagus, collectively called upper aerodigestive tract (UADT) cancers, but the evidence is considered as inconclusive. We hypothesised that the traditional Mediterranean dietary pattern may be more strongly inversely associated with UADT cancer risk than individual dietary components, and may explain the unexpectedly low incidence of these cancers in Greece. In the context of the European alcohol-related cancers and genetic susceptibility in Europe project, we have conducted a hospital-based case-control study in Athens, Greece, comparing 239 incident UADT cases and 194 hospital controls with admission diagnoses unrelated to tobacco, alcohol or diet.

Mineral apposition rates provide significant information on long-term effects in BMP-induced bone regeneration.

In this study, a CaP biomaterial was used as a carrier for rhBMP-2. Biomaterials were investigated in calvarial and femoral defects using a rabbit animal model, with unloaded biomaterials serving as control. Fluorochrome labels were administered at days 14 and 70.
