In animal cells, small RNA molecules, called piRNAs, defend the genome against selfish DNA elements such as transposons. In this issue, Klattenhoff et al. (2009) report that an HP1 family protein, Rhino, is required for piRNA generation and transposon silencing in Drosophila germline cells. The results provide a link between heterochromatin and piRNA-mediated genome defense.
Although percutaneous tracheostomy is a standardized procedure, rare major complications are still being evaluated and discussed. We describe a case of patient, with hemodynamic and respiratory stability, who displayed massive hemorrhage after 16 days of "Ciaglia Blue Rhino" tracheostomy. Unfortunately, neither prompt resuscitation maneuvers nor the surgical approach saved the life of patient.
We report a case of rhino-orbital zygomycosis in a 43-year-old male with well-controlled diabetes mellitus. The patient initially received liposomal amphotericin B, but the infection continued to progress, so posaconazole treatment was begun and eventually led to the cure of his infection. The causative agent was identified as Apophysomyces elegans, an emerging cause of zygomycosis in immunocom...
