[Cutaneous non-tuberculous mycobacterial infection following cord blood stem cell transplantation].

We describe a 4-year-old-girl with familial hemophagocytic lymphohistiocytosis (FHL) who developed disseminated cutaneous nontuberculous mycobacterial (NTM) infection after unrelated cord blood stem cell transplantation (uCBSCT). After transplantation, the patient developed steroid-refractory acute graft-versus-host disease, and was given methylprednisolone, cyclosporin and mycophenolate mofetil. Six months after uCBSCT, cutaneous lesions that looked like insect bites appeared and spread widely over the thighs.

A case of cochlear implant with internal mechanical failure.

Cochlear implantation has been performed since the 1970s and has been proven to be an effective treatment for profoundly deaf people. In some cases re-implantation has also been reported due to trauma causing implant damage, mechanical failure, extrusion, and wound infections, or device upgrade. We present a case of a 9-year-old boy with a cochlear implant in which mechanical failure occurred after a blow to his temporal region.
