PURPOSE: Enterovirus infection in children can manifest various disease and enterovirus have many serotypes. This study was aimed to investigate neurologic manifestations according to serotypes of enterovirus in pediatric inpatients in Incheon. METHODS: We collected the stool samples from the admitted pediatric patients in Inha University Hospital from January 2015 to September 2016. Enterovirus detection and serotypes identification were performed by real-time reverse transcriptase polymerase chain reaction (RT-PCR) and semi-nested RT-PCR. RESULTS: A total of 527 samples were collected during study period and 170 patients (32.2%) were diagnosed with enterovirus infections. Genetic sequences of enteroviruses were identified: echovirus 18 (50, 40.5%), enterovirus 71 (12, 9.6%), coxakievirus A10 (10, 8.0%), echovirus 6 (7, 5.6%). Virus in patient with meningitis were identified: echovirus 18 (15, 75%), coxakievirus B5 (2, 10%), enterovirus 71 (2, 10%), and echovirus 6 (1, 5%). Neurologic manifestations of echovirus 18 are headache (15, 30%), vomiting (17, 34%), meningeal irritation sign (10, 20.0%). And enterovirus 71 have headache (3, 25%), vomiting (3, 25%), meningeal irritation sign (2, 16.0%), seizure (1, 8.3%), neurologic sequelae (1, 8.3%). Echovirus 18 and neurologic manifestation have a statistically significant correlation with other serotypes (r=0.701, P < 0.01) CONCLUSION: Echovirus 18 infection was more prominent in neurological symptoms than in other serotypes. The major serotype of meningitis was echovirus 18 but there was no reported neurologic sequelae. Enterovirus infection has different neurological symptoms, depending on the serotypes.

Intracranial headaches, including migraines, are mediated by nociceptive activation of the trigeminal nucleus caudalis (TNC), but the precise mechanisms are poorly understood. We previously demonstrated that selective blockage of spinal sigma-1 receptors (Sig-1R) produces a prominent antinociceptive effect in several types of pain models. This study evaluates whether the Sig-1R antagonist (BD1047) has an antinociceptive effect on capsaicin (a potent C-fiber activator) induced headache models in rats. Intracisternal infusion of capsaicin evoked pain behavior (face grooming), which was significantly attenuated by BD1047 pretreatment. BD1047 consistently reduced capsaicin-induced Fos-like immunoreactivity (Fos-LI), a neuronal activator, in the TNC in a dose-dependent manner. Moreover, capsaicin-induced phosphorylation of N-methyl-D-aspartate receptor subunit 1 was reversed by BD1047 pretreatment in the TNC. These results indicate that the Sig-1R antagonist has an inhibitory effect on nociceptive activation of the TNC in the capsaicin-induced headache animal model.

PURPOSE: To describe the technical features of CT-guided percutaneous ethanol injection therapy (PEIT) for hepatic tumors that are undetectable or inaccessible under ultrasound guidance, to analyze its short-term therapeutic results, and to discuss its feasibility and limitations with a review of the related literature. MATERIALS AND METHODS: During a 22-month period, 17 patients with 28 hepatic tumors (27 hepatocellular carcinomas and one metastasis) underwent 38 sessions of CT-guided PEIT. Follow-up CT scanning was also performed. All tumors were undetectable or inaccessible under ultrasound guidance. The quantity of ethanol injected depended on their maximum diameter, which was 0.9 -5.1 (mean, 2.2) cm. To determine the puncture site and direction of the needle, the graduated grid system was used. A 21 or 22-G PEIT needle was introduced into the tumor stepwise, with intermittent CT monitoring, and if the CT images obtained immediately after initial injection demonstrated incomplete perfusion, an additional dose of ethanol was administered. During the follow-up period of 28 -619 (mean, 261) days, three-phase spiral CT scans were obtained. We focused on whether or not a viable portion of ablated tumor was present, and if so, the interval during which the extent of viable portion had changed, as well as the CT findings which suggested a predisposition to incomplete ablation. RESULTS: PEIT was successfully performed in all patients. During each session, 3 -30 (mean, 12.1) mL of ethanol was injected for 35 -115 (mean, 85) mins, with 1 -7 (mean, 3.7) trials to determine the puncture site and needle direction. The follow-up CT results showed that 20 tumors (71.4%) contained no viable portion, that this portion had decreased in four (14.3%), and was unchanged or had increased in four (14.3%). In the eight tumors for which multiple sessions were required, follow-up CT showed that the viable portion was absent or had decreased in size in all except one. In five of the patients with a tumor containing a viable portion at follow- up CT, the procedure was incomplete because of unendurable pain (n = 2) or noncooperation (n = 3). A CT finding which suggested a predisposition to incomplete ablation was a poor margin (n = 3). Complications included severe pain (n = 6) and scanty peritoneal hemorrhage (n = 1). CONCLUSION: Despite several limitations of our study, the therapeutic results of CT-guided PEIT appeared to be similar to or slightly worse than those of well-established ultrasound-guided PEIT with the former procedure, however, intermittent CT monitoring indicates whether perfusion is complete, and for this reason, CT-guided PEIT is believed to be an effective treatment modality when a hepatic tumor is undetectable or inaccessible under ultrasound guidance.

BACKGROUND: Patients with Parkinson's disease and mild cognitive impairment (PD-MCI) and patients with subcortical vascular mild cognitive impairment (svMCI) are known to have cognitive dysfunction. The aim of this study was to determine the cognitive characteristics that can be used to differentiate these two conditions. METHODS: Twenty-two PD-MCI and 22 svMCI patients seen in our neurodegenerative disease clinic, and 22 normal controls were recruited. These three groups were matched in terms of age, gender, and education level. Mild cognitive impairment was diagnosed according to the criteria of Petersen. svMCI should meet the criteria modified from those of Erkinjuntti. RESULTS: Analysis of covariance revealed that frontal executive dysfunction was prominent in both the PD-MCI and svMCI groups after adjusting for depression. The scores in word fluency and the Stroop test were lower in the svMCI group than in the PD-MCI group. Both groups exhibited decreased performance in verbal and visuospatial memory tests. The score in the verbal recognition test was lower in the PD-MCI group than in the svMCI group, which exhibited comparatively reduced visuospatial memory. The depression level was higher in the PD-MCI group than in the svMCI group, as assessed using the Geriatric Depression Scale. CONCLUSIONS: The impairment in frontal executive function was more severe in the svMCI group than in the PD-MCI group, which displayed severe impairment in verbal memory function. These differences in cognitive function may help to differentiate PD-MCI from svMCI, and to further the understanding of their pathophysiologies. PD-MCI patients also exhibited severe depressive mood, which raises the possibility of cognitive improvement through therapy.

BACKGROUND/OBJECTIVES: By the year 2050, thirty-eight percent of the Korean population will be over the age of 65. Health care costs for Koreans over age 65 reached 15.4 trillion Korean won in 2011, accounting for a third of the total health care costs for the population. Chronic degenerative diseases, including coronary heart disease (CHD), drive long-term health care costs at an alarming annual rate. In the elderly population, loss of independence is one of the main reasons for this increase in health care costs. Korean heath policies place a high priority on the prevention of CHD because it is a major cause of morbidity and mortality. SUBJECTS/METHODS: This evidence-based study aims to the estimate potential health care cost savings resulting from the daily intake of omega-3 fatty acid supplementation. Potential cost savings associated with a reduced risk of CHD and the medical costs potentially avoided through risk reduction, including hospitalizations and physician services, were estimated using a Congressional Budget Office cost accounting methodology. RESULTS: The estimate of the seven-year (2005-2011) net savings in medical costs resulting from a reduction in the incidence of CHD among the elderly population through the daily use of omega-3 fatty acids was approximately 210 billion Korean won. Approximately 92,997 hospitalizations due to CHD could be avoided over the seven years. CONCLUSIONS: Our findings suggest that omega-3 supplementation in older individuals may yield substantial cost-savings by reducing the risk of CHD. It should be noted that additional health and cost benefits need to be revisited and re-evaluated as more is known about possible data sources or as new data become available.

BACKGROUND: Extracellular nucleotides act as agonists to regulate a broad range of physiological processes by interacting with P2 receptors in various tissues including the kidney tubules. This study was undertaken to evaluate the effect of P2 receptor activation on PTH-dependent regulation of phosphate transport in the renal proximal tubular cells. METHODS: Proximal tubular cells were isolated from the rabbit kidney and grown as monolayers on 24 well culture plates. Phosphate uptake was determined by measuring the uptake of radiolabeled phosphate into cell monolayers. Cyclic AMP content was determined by radioimmunoassay using [3H]cAMP assay kit. RESULTS: Activation of P2 receptors with ATP exerted differential effects on phosphate uptake and cAMP generation. In the absence of PTH, it inhibited phosphate uptake and stimulated cAMP generation. In contrast, in the presence of PTH, it attenuated PTH-induced stimulation of cAMP generation and inhibition of phosphate uptake. The profile of the effects of different P2 agonists suggested that P2Y1- and P2Y2-like receptors are involved in the effects of ATP. The effect of ATP to interfere with the PTH-induced regulation was significantly blocked by calphostin C, pertussis toxin or PKC-depletion, whereas, the effects of ATP in the absence of PTH were abolished by indomethacin. CONCLUSION: Our results suggest that PKC-dependent modification of Gi proteins and, subsequently, reduced responsiveness of adenylate cyclases is responsible for the attenuating effect of ATP on the PTH-dependent regulation of phosphate transport in rabbit proximal tubule cells.
