Ramsay Hunt syndrome is a disorder characterized by herpetic eruptions on the auricle, facial paralysis, and vestibulocochlear dysfunction, and is attributed to varicella zoster virus infection in the geniculate ganglion. Ramsay Hunt syndrome accounts for about 10% cases of facial palsy. We report a 46-year-old healthy man developed left side skin vesicles on the face with severe pain. We thought of the trigeminal herpes zoster. He was treated with intravenous acyclovir, and stellate ganglion block daily. Four days later, brain magnetic resonance imaging revealed small areas of enhancement in the seventh cranial nerve and eighth cranial nerve, not in the fifth cranial nerve. Eight days later, the left facial palsy was come. We confirmed him as Ramsay Hunt syndrome. We started steroid therapy immediately. He recovered completely a month later. The patient was improved through the early antiviral therapy, steroid medication and stellate ganglion block.

OBJECTIVES: The purpose of the study was to examine dietary life characteristics such as knowledge, self-efficacy and dietary behavior of preschoolers in Namyangju, Kyunggi-province, Korea. METHODS: The survey questionnaire was developed based on literature review. Preschoolers aged 4-5 years (n=208) responded to the questionnaire to measure knowledge, self-efficacy, food preference, and dietary behavior. After excluding incomplete responses, the data of 197 subjects were used for analysis. RESULTS: Mean score of dietary life knowledge was 8.0 out of 12, showing a low level of knowledge. Two out of 12 knowledge items were significantly different by gender. Percentage of correct answer on items of 'foods to make bones strong' and 'kinds of fast foods' was higher in girls than in boys (p<0.05). Total score of self-efficacy regarding dietary life was 40.1 (possible score: 12~48), on average. Compared to girls, boys had more confidence in 'not over-eating', and 'eating balanced meals with meat, fish and vegetables' (p<0.05). Boys scored higher on total score of food preference than girls (p<0.01). The preference for fruits was quite high. Among food items, boys scored higher on the preference for rice (p<0.01), fish (p<0.01), pork (p<0.05), beef (p<0.05), milk (p<0.01), and ice cream (p<0.05) than girls. Boys also liked fast foods more than girls did, showing preference for chicken (p<0.01) and soda (p<0.05). Compared to girls, boys showed more desirable behavior in 'eating breakfast everyday' (p<0.01). Dietary behavior was significantly correlated with self-efficacy (r=0.52, p<0.01), food preference (r=0.35, p<0.01), and knowledge (r=0.25, p<0.01) of subjects. CONCLUSIONS: In this study, we observed differences in food preference by gender. Dietary behavior of preschoolers was correlated with several factors, including dietary life related knowledge, self-efficacy and food preference. Thus, it is needed to develop nutrition education programs focusing on increasing dietary life related knowledge and self-efficacy, and consider the differences in food preference of preschoolers by gender.

BACKGROUND/OBJECTIVES: Acanthopanax sessiliflorus is a native Korean plant and used as traditional medicine or an ingredient in many Korean foods. The free radical theory of aging suggests that cellular oxidative stress caused by free radicals is the main cause of aging. Free radicals can be removed by cellular anti-oxidants. MATERIALS/METHODS: Here, we examined the anti-oxidant activity of Acanthopanax sessiliflorus extract both in vitro and in vivo. Survival of nematode C. elegans under stress conditions was also compared between control and Acanthopanax sessiliflorus extract-treated groups. Then, anti-aging effect of Acanthopanax sessiliflorus extract was monitored in C. elegans. RESULTS: Stem extract significantly reduced oxidative DNA damage in lymphocyte, which was not observed by leaves or root extract. Survival of C. elegans under oxidative-stress conditions was significantly enhanced by Acanthopanax sessiliflorus stem extract. In addition, Acanthopanax sessiliflorus stem increased resistance to other environmental stresses, including heat shock and ultraviolet irradiation. Treatment with Acanthopanax sessiliflorus stem extract significantly extended both mean and maximum lifespan in C. elegans. However, fertility was not affected by Acanthopanax sessiliflorus stem. CONCLUSION: Different parts of Acanthopanax sessiliflorus have different bioactivities and stem extract have strong anti-oxidant activity in both rat lymphocytes and C. elegans, and conferred a longevity phenotype without reduced reproduction in C. elegans, which provides conclusive evidence to support the free radical theory of aging.

Turner syndrome (TS) is a relatively common chromosomal disorder and is associated with a range of comorbidities involving the cardiovascular system. Vascular abnormalities, in particular, are a common finding in cases of TS. However, dissection involving the vertebral arteries is rare. Here, we report the case of a 9-year-old girl with TS who had been treated with growth hormone replacement therapy for the past 3 years. She presented with weakness of both lower legs, and was ultimately diagnosed with spinal hemorrhage due to vascular malformation. We treated her with intravenous high dose dexamethasone (0.6 mg/kg) and she could walk without assistance after 6 days of treatment. In conclusion, when a patient with TS shows sudden weakness of the lower limbs, we should consider the possibility of spinal vessel rupture and try to take spine magnetic resonance imaging as soon as possible. We suggest a direction how to make a proper diagnosis and management of sudden vertebral artery hemorrhage in patients with TS.

OBJECTIVE: We investigated the performance of North Korean refugees on attention tasks, and the relationship between that performance and psychiatric symptoms. METHODS: Sustained and divided attention was assessed using the computerized Comprehensive Attention Test in North Korean refugees and in South Koreans. All participants also completed the Beck Depression Inventory, the Beck Anxiety Inventory, the Impact of Event Scale-Revised and the Dissociative Experiences Scale-II (DES-II). RESULTS: The North Korean refugees showed slower reaction times (RTs) on the visual sustained attention task compared to the South Koreans after controlling for age and sex. North Korean refugees had a greater number of omission errors (OEs) on the divided attention task and a higher standard deviation (SD) of RT. Total DES-II scores of the North Korean refugees were associated with the number of OEs and the SD of RT on the sustained attention task, and with the number of OEs on the divided attention task. CONCLUSION: North Korean refugees showed poorer performance on computerized attention tasks. In addition, attention deficit among North Korean refugees was associated with their dissociative experiences. Our results suggest that refugees may have attention deficits, which may be related to their psychiatric symptoms, particularly dissociation.

PURPOSE: To determine the change in lacrimal gland (LG) acinar cells induced by in vivo dry eye (DE). METHODS: Six to 8-week-old (C57BL/6) mice were placed in a controlled environment chamber at <20% humidity for 2 weeks, and a control group was bred in a normal environment. After these 2 weeks of dry eye (DE) induction, the mice were sacrificed and their LGs were collected. Lacrimal gland acinar cell organelle structures were observed with Transmission Electron Microscopy (TEM). TEM images were analyzed using the Image J program. RESULTS: The size of the LGs of DE-induced mice decreased compared to those of normal mice. Terminal deoxynucleotidyl transferase dUTP Nick End Labeling (TUNEL) staining was negative in DE-induced LGs. Under the TEM, the endoplasmic reticulum (ER) lumen was dilated and the lumen density increased in DE-induced mice. Additionally, cell organelles were surrounded by elongated ER lumens. The mitochondrial structure was destroyed and the number of vacuoles increased in the LGs of DE-induced mice. CONCLUSIONS: Structural changes of the LG developed due to DE induction. This suggests that the detailed mechanisms of these changes were ER stress and autophagy. However, there were no definite signs of apoptosis in the acinar cells of the DE-induced LGs. These findings are regarded as an important clue of the pathogenesis of non-Sjogren-type dry eye.

PURPOSE: In male patients with congenital adrenal hyperplasia (CAH), the presence of testicular adrenal rest tumors (TARTs) have been reported, however their prevalence and clinical manifestations are not well known. Untreated TARTs may lead to testicular structural damage and infertility. This study was conducted to investigate the prevalence of TARTs in male patients with CAH, and characterize the manifestations to identify contributing factors to TART. METHODS: Among 102 CAH patients aged 0-30 years, 24 male patients have been regularly followed up in our outpatient clinic at Severance Children's Hospital from January 2000 to December 2014. In order to reveiw the characteristics of TART patients, we calculated the mean levels of hormones during the 5 years before the time of investigation. Five patients underwent follow-up scrotal ultrasonography (US) after adjusting the dosage of glucocorticoids. RESULTS: TARTs were detected in 8 of the 13 patients (61.5%). The median age of TARTs diagnosis was 20.2 years with the youngest case being 15.5 years old. The mean serum level of adrenocorticotropic hormone (ACTH) was higher in the TARTs patient group compared to the non-TARTs group (P<0.05). The tumor size decreased in 3 cases, slightly increased in 1 case, and had no change in another case. CONCLUSION: The serum ACTH level might be associated with the growth promoting factor for TARTs, but the exact mechanism has not been clearly identified. Screening for TARTs using US is important in male patients with CAH for early-detection and prevention of ongoing complications, such as infertility.

beta-Glucosidase, which hydrolyzes cellobiose into two glucoses, plays an important role in the process of saccharification of the lignocellulosic biomass. In this study, we optimized the activity of beta-glucosidase of brown-rot fungus Fomitopsis pinicola KCTC 6208 using the response surface methodology (RSM) with various concentrations of glucose, yeast extract and ascorbic acid, which are the most significant nutrients for activity of beta-glucosidase. The highest activity of beta-glucosidase was achieved 3.02% of glucose, 4.35% of yeast extract, and 7.41% ascorbic acid where ascorbic acid was most effective. The maximum activity of beta-glucosidase predicted by the RSM was 15.34 U/mg, which was similar to the experimental value 14.90 U/mg at the 16th day of incubation. This optimized activity of beta-glucosidase was 23.6 times higher than the preliminary activity value, 0.63 U/mg, and was also much higher than previous values reported in other fungi strains. Therefore, a simplified medium supplemented with a cheap vitamin source, such as ascorbic acid, could be a cost effective mean of increasing beta-glucosidase activity.

Background/Aims:
Potassium channel tetramerization domain containing 17 (KCTD17) protein, an adaptor for the cullin3 (Cul3) ubiquitin ligase complex, has been implicated in various human diseases; however, its role in hepatocellular carcinoma (HCC) remains elusive. Here, we aimed to elucidate the clinical features of KCTD17, and investigate the mechanisms by which KCTD17 affects HCC progression.
Methods:
We analyzed transcriptomic data from patients with HCC. Hepatocyte-specific KCTD17 deficient mice were treated with diethylnitrosamine (DEN) to assess its effect on HCC progression. Additionally, we tested KCTD17-directed antisense oligonucleotides for their therapeutic potential in vivo.
Results:
Our investigation revealed the upregulation of KCTD17 expression in both tumors from patients with HCC and mouse models of HCC, in comparison to non-tumor controls. We identified the leucine zipper-like transcriptional regulator 1 (Lztr1) protein, a previously identified Ras destabilizer, as a substrate for KCTD17-Cul3 complex. KCTD17-mediated Lztr1 degradation led to Ras stabilization, resulting in increased proliferation, migration, and wound healing in liver cancer cells. Hepatocyte-specific KCTD17 deficient mice or liver cancer xenograft models were less susceptible to carcinogenesis or tumor growth. Similarly, treatment with KCTD17-directed antisense oligonucleotides (ASO) in a mouse model of HCC markedly lowered tumor volume as well as Ras protein levels, compared to those in control ASO-treated mice.
Conclusions
KCTD17 induces the stabilization of Ras and downstream signaling pathways and HCC progression and may represent a novel therapeutic target for HCC.
