ABSTRACT
The aim of this study is to analyze dysphagic symptoms of a patient with Huntington's disease (HD) who had having difficulty in swallowing. The patient was a 66-year-old female with HD. Inspection of self-feeding at bedside and videofluorographic swallowing assessment were performed. The features at self-feeding were the tendency of rapid eating, inability for smooth transportation of food to oral cavity, weak lip closure, which resulted in falling of food and eating it again. The videofluorography indicated clumsy tongue movement and postural instability by chorea which caused discoordination between oral and pharyngeal stage. Those ended in spill of liquid to the pharynx and retention of bolus in the oral cavity and vallecula, and aspiration did not occur. Pudding was carefully chewed because of the patient's alertness to the examination. The cognitive disturbance and choreic movement caused dysphagia at the preparatory and oral stages, and chorea also produced the discoordication between the oral and pharyngeal stage. The change of the shape of cups and stable posture were advised to lessen the chance of her aspiration.

OBJECTIVE: Non-herpetic acute limbic encephalitis (non-herpetic ALE) is regarded as a new subgroup of limbic encephalitis. In the present study, clinical findings and cerebrospinal fluid (CSF) cytokines in patients with non-herpetic ALE were investigated. PATIENTS AND METHODS: For adult inpatients in our hospital and related hospitals from 1996 to 2001, non-herpetic ALE was examined according to the criteria described in this study. Six patients were diagnosed as having non-herpetic ALE, and their clinical data and magnetic resonance imaging (MRI) were analyzed. In the CSF samples of the 6 patients with non-herpetic ALE and 6 patients with herpes simplex encephalitis (HSE), the concentrations of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, IL-6, and interferon (IFN)-gamma were determined using sandwich-type enzyme-linked immunosorbent assay (ELISA) kits. RESULTS: The six patients with non-herpetic ALE showed all the acute encephalitis features, such as fever, altered consciousness, seizures, memory impairment, and mild CSF pleocytosis. MRI demonstrated selective abnormal signals in the limbic system, including the bilateral hippocampi and amygdalae. The levels of CSF IL-6 and IFN-gamma in patients with non-herpetic ALE were significantly lower than those in patients with HSE (p<0.05 and p<0.01, respectively). The levels of both TNF-alpha and IL-1beta were below the detection limits in both groups. CONCLUSION: Six patients were newly diagnosed as having non-herpetic ALE in this study. These patients revealed both acute limbic encephalitis and MRI abnormalities in the bilateral hippocampi and amygdalae. The levels of IL-6 and IFN-gamma in the CSF of patients with non-herpetic ALE were significantly lower than those of patients with HSE, possibly reflecting an immunological process in this type of ALE rather than direct viral infection.

OBJECTIVE: Epstein-Barr virus (EBV), a lymphotropic herpes virus causing infectious mononucleosis (IM), also causes various central nervous system (CNS) infections. In the present study, EBV CNS infections were investigated. PATIENTS AND METHODS: For adult inpatients in our hospital and related hospitals between 1984-2002, CNS syndromes with IM symptoms were examined, and serologic positives were assessed according to established criteria. Polymerase chain reaction (PCR) was performed for cerebrospinal fluid (CSF) from seven patients. RESULTS: Ten patients with EBV-related CNS infections were found; their mean age was 36 years (20-79 years). The neurologic forms were as follows: acute encephalitis (4 patients), acute cerebellar ataxia (1), acute disseminated encephalomyelitis (ADEM) (2), myelitis (1), and meningitis (2). The PCR from CSF was positive in two patients with meningitis, one patient with ADEM, and one patient with encephalitis-associated chronic EVB infection. One case of encephalitis and another of relapsing ADEM were attributed to chronic EBV infection. CONCLUSION: Our study identified a variety of EBV-related CNS infections. EBV CNS infections are divided into two groups: 1) CNS syndromes associated with primary EBV or reactivated infection, and 2) those associated with chronic EBV infection; it is notable that in the former, diverse CNS syndromes including ADEM can occur, whereas in the latter, chronic or recurrent CNS syndromes are produced.
