[Successful treatment of enterohemorrhagic Escherichia coli O111-induced hemolytic-uremic syndrome and acute encephalopathy].

We report a case of a woman in her twenties with enterohemorrhagic Escherichia coli O111-induced hemolytic-uremic syndrome who developed acute encephalopathy on day 5 of admission. She recovered after treatment with steroid pulse therapy, plasmapheresis, and recombinant thrombomodulin, without any adverse sequelae. We report this interesting case and provide a summary of the recent outbreak of enterohemorrhagic Escherichia coli O111.

Liver sarcoidosis that presented with dysphagia.

We report a case of liver sarcoidosis with dysphagia. Although akinesia of the soft palate, disappearance of the palatal reflex, and pyramidal signs indicated brainstem lesions, brain magnetic resonance imaging showed no lesion and the focus was obscure. Iritis, parotiditis, and hilar lymphadenopathy supported the diagnosis of sarcoidosis. However, lung biopsy was normal. Finally, sarcoidosis was diagnosed by liver biopsy. We speculated that microgranulomas in the brainstem that did not exhibit imaging abnormalities causing the neurological symptoms and that liver biopsy can be an effective diagnostic tool even for cases that presented with neurological signs, but no gastrointestinal symptom.
