First endocavitary treatment with cord blood platelet gel for perianal fistula.

Cord blood platelet gel is prepared by activation of coagulation in a platelet concentrate obtained from cord blood. During the process of clot formation, platelet alpha-granules release growth factors that promote tissue repair. However, in the form of gel, it is not possible to inject it into small, narrow and deep cavities.

Molecular dissection of the VHL gene in solitary capillary hemangioblastoma of the central nervous system.

Capillary hemangioblastomas (HGBs) of the CNS occur either sporadically or as part of the von Hippel-Lindau (VHL) syndrome. Molecular characterizations of the VHL gene in sporadic HGBs at the somatic level have been limited to date. We investigated the VHL gene in 57 patients most of whom (55 [96%] of 57) had a solitary CNS HGB at the time of surgery.
