SummaryNorovirus is an emerging pathogen that causes gastroenteritis outbreaks. Here, we reported an adult female case of norovirus-related encephalitis/encephalopathy (NvREE) with abnormal behaviour, apathy, motor aphasia, bradykinesia and gait disturbance. We treated the patient with intravenous methyl-prednisolone pulse therapy and she recovered quickly. There were slight abnormal signals in the cortex of the opercular part and insula on the MRI fluid-attenuated inversion-recovery (FLAIR) image, generalised slow wave as a background activity in her EEG and cerebrospinal fluid pleocytosis, which restored soon after her recovery. We successfully detected the norovirus genome in stool samples from all seven family members. This is a first case report of an adult NvREE with detection of pathogenic evidence. There could be more cases of NvREE with mild neuropsychiatric symptoms, considering the increasing outbreaks each year. BACKGROUND

We present a case of a patient with clinically definite ALS, who had earlier suffered from Kartagener syndrome, which is characterized by the triad comprising chronic sinusitis, bronchiectasis, and situs inversus. Recent linkage and mutational analyses identified several genes that are responsible for Kartagener syndrome. Most of them encode subunits of axonemal dyneins, highlighting the importance of dynein motors to ciliary motility. Recent data indicate that defects in cytoplasmic dynein-mediated retrograde axonal transport are involved in the etiology of ALS. Genes encoding the dynein heavy chain of cytoplasmic and outer arm axonemal dyneins are reported to have similar sequences in their central and 3'-end regions. Although a causal link between ALS and Kartagener syndrome has not yet been definitely established, the precise relationship between disrupted axonemal dynein function in Kartagener syndrome and motor neuron death should be investigated.
