A 42-year-old man was admitted to the Saiseikai Fukuoka General Hospital on March 22, 1985 with complaints of nausea, vomiting and headache which had continued for twelve days. On physical examinations, multiple subcutaneous nodules were noted in the chest, abdomen and extremities with dilated veins in the chest wall. Furthermore, the discoloration of the skin attributable to the venous occlusion was noted in the left foot. Neurological examinations failed to reveal any abnormalities except for moderate choked disc in bilateral ocular fundi. Spinal puncture revealed CSF pressure as high as 350 mmH2O with slight increase in cell numbers. CT demonstrated small intracerebral hematomas bilaterally in occipital lobes with evidence of "empty delta" sign in the superior sagittal sinus. On angiographical findings, the superior sagittal sinus was not demonstrated in venous phase and the blood was drained mainly through the paravertebral plexus and the pterygoid plexus without any abnormalities in arterial and capillary phases. Serological examination revealed a hypercoagulability and hyperlipidemia especially in LDL (Low Density Lipoprotein) and VLDL (Very Low Density Lipoprotein). On etiological considerations, all of these abnormalities seemed to be derived from the hyperlipidemia. Furthermore, multiple symmetrical lipomatosis was defined as a "lipoprotein storage disease" in which laboratory examinations revealed hyperlipidemia especially in LDL and in some subfraction of HDL. Although not a typical case, there must be some possibilities that the lipomatosis of this case is secondary to disorder of lipid metabolisms. In conclusion, all of various pathological conditions observed in this case were considered to be due to the disorder of lipid metabolism.

A patient presenting with subarachnoid haemorrhage and high lipid concentrations in the cerebrospinal fluid (taken at lumbar puncture), who has later shown to have type V hyperlipidaemia is described. This case, so far as can be ascertained by the authors, is the first report of hyperlipidaemia being diagnosed from CSF examination.

The characteristics and metabolism of lipoproteins were reviewed. Apolipoproteins has been studied in the fields of neurological diseases as well as hyperlipidemia. A highly significant association between apolipoprotein E (ApoE) epsilone 4 allele and late-onset familial and sporadic Alzheimer's disease (AD) was reported. The recent studies also described the following: (1) late-onset familial AD linked to the proximal long arm of chromosome 19; (2) the presence in the CSF of several proteins, one of which was ApoE, what bound to immobilized amyloid beta-peptide (beta A4) with high avidity; and (3) staining by antisera to ApoE of senile plaques, neurofibrillary tangles, and cerebral vessel amyloid deposits in AD brains. Furthermore, (4) both purified ApoE isomers, ApoE3 and ApoE4, bound to beta A4 synthetic peptide, forming a complex that resisted dissociation by boiling in sodium dodecyl sulfate, but the isomers showed different kinetics in doing so: binding by ApoE4 was observed in minutes, while binding by ApoE3 required hours; and (5) ApoE4 did not bind to beta A4 peptide at pH less than 6.6, while ApoE3 bound to beta A4 peptide from pH7.6 to 4.6. We studied ApoE phenotype expression and the corresponding allele frequencies (epsilon 2, epsilon 3 and epsilon 4) in Japanese patients with late-onset sporadic AD. The frequency of the ApoE epsilon 4 allele was obviously high in AD patients compared with the controls, but it was not different between vascular dementia patients and the controls. These results suggest that ApoE isoforms may play a functional role in the pathophysiology of late-onset familial and sporadic AD and that the isoform-specific difference in beta A4 binding may be involved in forming the AD lesion.

Objective. Stroke is a clinical diagnosis, with a history and physical examination significant for acute onset focal neurological symptoms and signs, often occurring in patients with known vascular risk factors and is frequently confirmed radiographically. Case Report. A 79-year-old right-handed woman, with a past medical history of hypertension, hyperlipidemia, and prior transient ischemic attack (TIA), presented with acute onset global aphasia and right hemiparesis, in the absence of fever or prodrome. This was initially diagnosed as a proximal left middle cerebral artery (MCA) stroke. However, CT perfusion failed to show evidence of reduced blood volume, and CT angiogram did not show evidence of a proximal vessel occlusion. Furthermore, MRI brain did not demonstrate any areas of restricted diffusion. EEG demonstrated left temporal periodic lateralized epileptiform discharges (PLEDs). The patient was empirically loaded with a bolus valproic acid and started on acyclovir, both intravenously. CSF examination demonstrated a pleocytosis and PCR confirmed the diagnosis of herpes simplex viral encephalitis (HSVE). Conclusions. HSVE classically presents in a nonspecific fashion with fever, headache, and altered mental status. However, acute focal neurological signs, mimicking stroke, are possible. A high degree of suspicion is required to institute appropriate therapy and decrease morbidity and mortality associated with HSVE.

OBJECTIVE Idiopathic normal pressure hydrocephalus (iNPH) is characterized by ventriculomegaly, gait difficulty, incontinence, and dementia. The symptoms can be ameliorated by CSF drainage. The object of this study was to identify factors associated with shunt-responsive iNPH. METHODS The authors reviewed the medical records of 529 patients who underwent shunt placement for iNPH at their institution between July 2001 and March 2015. Variables associated with shunt-responsive iNPH were identified using bivariate and multivariate analyses. Detailed alcohol consumption information was obtained for 328 patients and was used to examine the relationship between alcohol and shunt-responsive iNPH. A computerized patient registry from 2 academic medical centers was queried to determine the prevalence of alcohol abuse among 1665 iNPH patients. RESULTS Bivariate analysis identified associations between shunt-responsive iNPH and gait difficulty (OR 4.59, 95% CI 2.32-9.09; p < 0.0001), dementia (OR 1.79, 95% CI 1.14-2.80; p = 0.01), incontinence (OR 1.77, 95% CI 1.13-2.76; p = 0.01), and alcohol use (OR 1.98, 95% CI 1.23-3.16; p = 0.03). Borderline significance was observed for hyperlipidemia (OR 1.56, 95% CI 0.99-2.45; p = 0.054), a family history of hyperlipidemia (OR 3.09, 95% CI 0.93-10.26, p = 0.054), and diabetes (OR 1.83, 95% CI 0.96-3.51; p = 0.064). Multivariate analysis identified associations with gait difficulty (OR 3.98, 95% CI 1.81-8.77; p = 0.0006) and alcohol (OR 1.94, 95% CI 1.10-3.39; p = 0.04). Increased alcohol intake correlated with greater improvement after CSF drainage. Alcohol abuse was 2.5 times more prevalent among iNPH patients than matched controls. CONCLUSIONS Alcohol consumption is associated with the development of shunt-responsive iNPH.
