We report a case of a 40-year-old man affected by the Kearns-Sayre syndrome who underwent an elective laparoscopic cholecystectomy under general anaesthesia. We describe the management of general anaesthesia in this rare myopathy, with emphasis on the use of rocuronium as muscle blocking agent. Induction was achieved with propofol and fentanyl, and general anaesthesia was maintained with fentan...

The Kearns-Sayre syndrome is a neuromyopathic disorder associated with mitochondrial abnormalities and characterized by the triad of chronic external ophthalmoplegia, atypical pigmentary retinopathy, and progressive conduction system disorders. Ragged red muscle fibers that seem to contain an excess of altered mitochondria are observed. The disease affects both sexes alike, during the first or ...

The ratio of shear viscosity to entropy density η/s of any material in nature has been conjectured to have a lower bound of 1/4π, the famous KSS bound. We examine string theory models for evidence in favour of and against this conjecture. We show that in a broad class of models quantum corrections yield values of η/s just above the KSS bound. However, incorporating matter fields in the fundamen...
