Facial motor evoked potential (FMEP) by multi-pulse transcranial electrical stimulation (mpTES) can complement free-running electromyography (EMG) and direct facial nerve stimulation to predict the functional integrity of the facial nerve during cerebello-pontine angle (CPA) tumor surgery. The purpose of this paper is to examine the standardized test methods and the usefulness of FMEP as a predictor of facial nerve function and to minimize the incidence of facial paralysis as an aftereffect of surgery. TES was delivered through electrode Mz (cathode) - M3/M4 (anode), and extracranially direct distal facial muscle excitation was excluded by the absence of single pulse response (SPR) and by longer onset latency (more than 10 ms). FMEP from the orbicularis oris (o.oris) and the mentalis muscle simultaneously can improve the accuracy and success rate compared with FMEP from the o.oris alone. Using the methods described, we can effectively predict facial nerve outcomes immediately after surgery with a reduction of more than 50% of FMEP amplitude as a warning criterion. In conclusion, along with free-running EMG and direct facial nerve stimulation, FMEP is a useful method to reduce the incidence of facial paralysis as a sequela during CPA tumor surgery.
This study was to investigate the correlation among swallowing function, dietary level, cognitive function, daily living, and comparison for general characteristics in stroke patients with dysphagia. Subjects of this study participated to 56 stroke patients with dysphagia. Outcome measures is evaluated by Functional Dysphagia Scale(FDS), and Amerian Speech-Language-Hearing Association National Outcomes Measurements System(ASHA NOMS), and Korean Mini-Mental State Examination(K-MMSE), and Korean Modified Barthel Index(K-MBI). Collected all data analyezed to independent t test for four assessments, and general characteristics of study subjects analyzed by pearson correlation coefficient for four assessments. Results of study, swallowing function according to lesion location differed significantly(p<.05). Cognitive function according to onset duration differed significantly(p<.05). Age of subjects and dietary level, cognitive function showed a significant correlation(p<.05). Swallowing function and dietary level, cognitive function showed a significant correlation(p<.05). Cognitive function and dietary level, daily living showed a significant correlation(p<.05). Based on current results, we suggest that swallowing rehabilitation for stroke patients with dysphagia performed with consideration for cognitive function and characteristic of patients.

Inflammatory and oxidative stimuli play a critical role not only in the process of transforming normal cells into cancer cells, but also in the proliferation process of cancer cells. Sipyukmiryukieum (SYMRKU), a traditional Korean herb-combined remedy, is composed of 16 kinds of herbal medicines, which were recorded for "Ongjeo" treatment in "Dongeuibogam". In this study, we investigated the inhibitory effect of SYMRKU against inflammatory and oxidative responses in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. Our results showed that SYMRKU significantly inhibited LPS-induced secretion of pro-inflammatory mediators including nitric oxide (NO) and prostaglandin $E_2$ without showing any significant cytotoxicity. Consistent with these results, SYMRKU down-regulated LPS-induced expression of their regulatory enzymes such as inducible NO synthase and cyclooxygenase-2. SYMRKU also inhibited LPS-induced production and expression of pro-inflammatory cytokines such as tumor necrosis factor-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-6. In addition, SYMRKU significantly reduced the production of reactive oxygen species by LPS and showed a strong, which was associated with induction of nuclear factor erythroid 2-related factor 2 and heme oxygenase-1 expression. Although further studies are needed to fully understand the anti-inflammatory effects associated with the antioxidant capacity of SYMRKU, the findings of the current study suggest that SYMRKU may have potential benefits by inhibiting the onset and/or treatment of inflammatory and/or oxidative diseases.

Purpose: Campylobacter species are common causes of bacterial enteritis. There is limited knowledge on its prevalence and clinical features because of its fastidious culture conditions. The purpose of this study was to identify the clinical features of Campylobacter enteritis in children. Methods: We obtained stool specimens from patients diagnosed with acute gastroenteritis in the Department of Pediatrics, Nowon Eulji Medical Center (NEMC) and identified the pathogens by performing cultures or polymerase chain reactions (PCR). We retrospectively reviewed the medical records of patients with Campylobacter enteritis at NEMC between January 2012 and December 2017. Results: Overall, 123 patients were diagnosed with Campylobacter enteritis (60 by culture and PCR in EnterNet and 110 by multiplex PCR). The median (interquartile range [IQR]) age of patients was 12 years (IQR, 8 to 16 years). The disease occurred all year round, but 69.9% from June to September. Symptoms included diarrhea (97.6%), fever (96.7%), abdominal pain (94.3%), vomiting (37.4%), and headache (34.1%). Compared with other treatments, treatment with azithromycin was associated with a shorter hospitalization period (P<0.05). Conclusions: Campylobacter enteritis is common during summer and mostly infects adolescent patients. It causes severe abdominal pain and fever preceding the onset of diarrhea. Prompt diagnosis and appropriate use of antibiotics reduces the duration of the disease.

Objectives Clozapine is the most effective atypical antipsychotic agent for the treatment-resistant schizophrenia (TRS), however, only 40%-70% of TRS patients respond to clozapine. Moreover, TRS encompasses various symptom dimensions. Therefore, augmentation with other medications for clozapine is frequently applied. However, the prescription pattern of clozapine and combined medications in Korea is yet to be examined. This study aims to investigate the maintenance treatment pattern of clozapine and augmentation agents in one Korean tertiary hospital. Methods The patients with schizophrenia spectrum disorders under clozapine maintenance, defined as one-year clozapine continuation, were subjected for analysis. Medication data at one-year time-point after clozapine initiation was extracted and analyzed. Results Among total 2897 patients having clozapine prescription experience from January 2000 to December 2018, 1011 patients were on clozapine maintenance. The mean age of clozapine initiation was 30.2 ± 11.3 years, and the maintenance dose of clozapine was 217.8 ± 124.3 mg/day. Combination rate of antipsychotics, mood stabilizers, and antidepressants were 43.5%, 25.3%, 38.6%, respectively. Most frequently prescribed drugs in each category were aripiprazole, valproate, and sertraline. Olanzapine equivalent dose of combined antipsychotics was 10.4 ± 7.7 mg/day. Male patients were prescribed higher dose of combined antipsychotics and higher rate of antidepressants. Female patients had later onset of clozapine prescription. Patients with two or more combined antipsychotics were prescribed higher dose of clozapine and higher rate of antidepressants compared to patients with one combined antipsychotic. Conclusions Taken together, among the patients taking clozapine, a substantial rate of patients were under polypharmacy. The present findings based on the real-world prescription pattern could provide the valuable clinical information on the treatment of TRS-related conditions.
Cytochrome P450 1A2 (CYP1A2) is a member of the cytochrome P450 superfamily enzymes in mammals and plays a major role in metabolizing endogenous hormones in the liver. In recent days, CYP1A2 expression has been found in not only the liver but also other tissues including the pancreas and lung. However, little information is available regarding the expression of CYP1A2 in the ovary, in spite of the facts that the ovarian follicle growth and atresia are tightly associated with controls of endocrine hormonal networks. Therefore, the expression of CYP1A2 in the ovaries of prepubertal and pubertal rats was investigated to assess its expression pattern and puberty-related alteration. It was demonstrated that the expression level of CYP1A2 was significantly (p < 0.01) higher in the pubertal ovaries than prepubertal counterparts. At the ovarian follicle level in both groups, whereas CYP1A2 expression was less detectable in the primordial, primary and secondary follicles, the strongly positive expression of CYP1A2 was localized in the granulosa cell layers in the antral and pre-ovulatory follicles. However, the ratio of CYP1A2-positive ovarian follicle was significantly (p < 0.01) higher in the ovary of pubertal group (73.1 ± 3.1%) than prepubertal one (41.0 ± 10.5%). During the Immunofluorescence, expression of CYP1A2 was mainly localized in Fas-positive follicles, indicating the atretic follicles. In conclusion, these results suggested that CYP1A2 expression was mainly localized at the atretic follicular cells and affected by the onset of puberty. Further study is still necessary but we hypothesize that CYP1A2 expresses in the atretic follicles to metabolize residue of the reproductive hormones. These findings may have important implications for the fields of reproductive biology of animals.

Particulate matter (PM) is known to be involved in the onset and progression of various diseases by promoting oxidative and inflammatory reactions as air pollutants containing various small particles that are harmful. In this study, the protective efficacy of herbal medicines was evaluated in human corneal epithelial cells (hCECs) to select natural products that can protect the eye, the primary organ directly exposed to external pollutants from PM. As a result, five candid ate herbal medicines [Cheonmundong, Asparagus Rhizome; Seokchangpo, Aciru Gramineri Rhizoma; Hwangryeon, Coptidis Rhizoma; Gamgug, Chrysanthemi Indici Flos; and Geumjanhwa (Marigold flower petals)] which showed inhibitory efficacy on PM2.5-induced cytotoxicity, were selected from among 12 candidate herbal medicines. To evaluate the antioxidant activity of these candidate substances, the reactive oxygen species (ROS) scavenging ability was investigated, and it was found that the extracts of Seokchangpo, Cheonmundong and Hwangryeon showed a significant inhibitory effect on PM2.5-induced ROS production, which was correlated with the preservation of mitochondrial activity. In addition, it was confirmed that they could block DNA damage caused by PM2.5 through analysis of 8-hydroxy-2'-deoxyguanosine generation and phosphorylated-H2A histone family member X (γ- H2AX) expression. Furthermore, the increase in inflammasome activity and inflammatory response in PM2.5-treated hCECs was also canceled in the presence of these extracts. Although additional studies are needed, the results of this study will be used as primary data to find novel natural compounds that protect hCECs from PM.
This study examined the participation of the people with stroke living in the community in terms of productivity, leisure, and social domain, and identified the effect on disability acceptance and anxiety. For data collection, from October 2018 to January 2019, data on disability acceptance, anxiety, and participation were collected from 192 people with stroke who used welfare centers and community services. For general characteristics, t-test and one-way ANOVA were used to compare participation according to descriptive statistics and general characteristics. Pearson correlation analysis was used for correlation between variables, and multiple regression analysis was used to identify causality. As the result, factors affecting the productivity of participation were labor(β=.28, p<.001), de-emphasis on disability salience(β=.14, p<.05), compensatory(β=.22, p<.01), and subjective anxiety(β=-.35, p<.05), and the explanatory power was 33%(F=9.44, p<.001). Leisure was expressed as self-satisfaction with disability(β=.18, p<.05) and the compensatory(β=.18, p<.05), and had an explanatory power of 23%(F=6.32, p<.001). Social activity was labor(β=.19, p<.01), and subjective anxiety(β=-.51, p<.05), which showed 23%(F=6.05, p<.001) of explanatory power. This suggests the importance of psychosocial factors for a changed life after the onset of a stroke, and a practical approach is needed to construct and apply programs to improve participation.

Purpose: Antibiotic exposure during pregnancy may affect the fetus and newborn in many ways. This study investigated the impact of prenatal antibiotic exposure duration on neonatal outcomes in very preterm (VP) or very low birth weight (VLBW) infants. Methods: From September 2015 to December 2020, preterm infants with gestational age less than 32 weeks or with a BW less than 1,500 g who were admitted to the neonatal intensive care unit, and their mothers were enrolled. Prenatal antibiotic exposure was defined as antibiotics received by mothers before delivery, and the patients were categorized into the non-antibiotic group, short-duration (SD; ≤7 days) group, or long-duration (LD; >7 days) groups. Results: A total of 93 of 145 infants were exposed to prenatal antibiotics, among which 35 (37.6%) were in the SD group and 58 (62.4%) were in the LD group. Infants in the LD group had a significantly higher birth weight-for-gestational-age (BW/GA) Z-score than those in the non-antibiotic group, even after the adjustment for confounding factors (beta, 0.258; standard error, 0.149; P<0.001). Multivariate logistic regression analysis showed that prolonged prenatal antibiotic exposure was independently associated with death (adjusted odds ratio [aOR], 8.926; 95% confidence interval [CI], 1.482-53.775) and composite outcomes of death, necrotizing enterocolitis (NEC), and late-onset sepsis (LOS) (aOR, 2.375; 95% CI, 1.027-5.492). Conclusions: Prolonged prenatal antibiotic exposure could increase the BW/GA Z-score and the risk of death and composite outcomes of death, NEC, and LOS in VP or VLBW infants.
