Gustatory dysfunction is an uncommon complication following tonsillectomy with a potential impact on the quality of life. This retrospective study was undertaken to evaluate the incidence of post-tonsillectomy dysgeusia and its relationship to wound healing and pain. A retrospective chart review of 100 patients who had undergone tonsillectomy between June and December 2008 at a single tertiary care institution was performed.

Background: Electrophysiological techniques such as laser and contact heat evoked pain-related potentials are very useful for studying trigeminal and somatic pain transmission in humans. These methods are, however, partly invasive, expensive, and therefore not available for broad clinical use. We recently proposed a novel technique of noninvasive transcutaneous electrical stimulation.

To optimize the efficiency of a Minimalistic Immunogenically Defined Gene Expression (MIDGE) vector, peptides containing proven (SV40 T-antigen and bovine herpesvirus-1 VP8) or putative (herpes simplex virus-1 VP22) nuclear localization signals (NLSs) were linked to a MIDGE vector encoding a truncated, secreted form of BHV-1 glycoprotein D (tgD) (MIDGE-tgD). Conjugation of an NLS to the MIDGE-tgD vector improved the tgD expression in vitro and the humoral and cellular immune responses induced in mice in vivo. The NLS from BHV-1 VP8 was most efficient at enhancing the tgD production and tgD-specific immune responses when conjugated to the MIDGE-tgD vector.

Purpose: Childhood Philadelphia chromosome positive (Ph(+)) acute lymphoblastic leukemia (ALL) has a poor prognosis. Because leukemia cell burden is reduced but not eradicated by polychemotherapy, improved treatment strategies should enhance those immune mechanisms responsible for the maintenance of complete remission. The aim of this study was to evaluate the protection of mice challenged with the syngeneic Ph(+) ALL cell line BM185 using genetically modified leukemia cell vaccines and immunomodulating oligonucleotides.

Background: The beneficial effect of modulating an allospecific immune response by ballistic IL-4 and CTLA4 gene transfer to deliver minimalistic immunologically defined gene expression (MIDGE) vectors into the corneal epithelium was demonstrated in corneal transplantation. However, side effects reduced graft survival in control animals after ballistic transfer without DNA.

Methods: An adapter was constructed for the gene gun apparatus to enlarge and keep constant the distance between the gun and the cornea.
