Pindborg Tumor-An Uncommon Odontogenic Tumor Detected by 68Ga-DOTATOC.

A 62-year-old-woman with a suspected Tumor-induced-osteomalacia (TIO), a rare neoplastic syndrome that results in renal phosphate wasting with hypophosphatemia, underwent Ga-DOTATOC PET/CT on the suspicion of a mesenchymal tumor producing Fibroblast growth factor 23 (FGF23). Imaging revealed a small osteolytic, somatostatin receptor (SSTR) positive lesion containing calcifications in the alveolar process of the maxilla. No other SSTR-positive focus was found.

Evaluating Molecular Docking Software for Small Molecule Binding to G-Quadruplex DNA.

G-quadruplexes are four-stranded nucleic acid secondary structures of biological significance and have emerged as an attractive drug target. The G4 formed in the promoter (MycG4) is one of the most studied small-molecule targets, and a model system for parallel structures that are prevalent in promoter DNA G4s and RNA G4s. Molecular docking has become an essential tool in structure-based drug discovery for protein targets, and is also increasingly applied to G4 DNA.

[Sebaceous carcinoma of the eyelids--case reports and review of the literature].

Background: Sebaceous carcinomas are among the most rarely found skin tumours (0.2 - 4.6 %).

[Incorporation of multiple foreign bodies due to borderline personality disorder].

Background: Autoaggressive behaviour is one of the pathognomonic characteristics in patients with borderline personality disorder. Clinical symptoms of such behaviour can be the self-induced incorporation of foreign bodies. In the head and neck area, this form of autoaggressivity causes primary or secondary infectious complications with different clinical manifestations.

Microvascular submandibular gland transfer for severe cases of keratoconjunctivitis sicca.

Free submandibular salivary gland transfer was investigated as a surgical method for the treatment of severe keratoconjunctivitis sicca. In an animal model, we examined the tolerance of warm ischemia of the submandibular gland. After temporary interruption of the blood supply (1 to 6 hours), the morphologic changes in the submandibular gland were analyzed histologically and immunohistochemically in 41 rabbits.
