Purpose: Recently, many studies have demonstrated that application of external stimulation can modulate cortical excitability of the human brain. We attempted to observe cortical excitability using functional magnetic resonance imaging (fMRI) during the application of transcranial direct current stimulation (tDCS) or functional electrical stimulation (FES). Methods: We recruited two healthy subjects without a history of neurological or psychiatric problems. fMRI scanning was done during? each constant anodal tDCS and FES session, and each session was repeated three times. The tDCS session consisted of three successive phases (resting phase: 60sec dummy cycle: 10sec tDCS phase: 60sec). The FES session involved stimulation of wrist extensor muscles over two successive phase (resting phase: 15sec FES phase: 15sec). Results: The average map of the tDCS and FES analyses showed that the primary sensory-motor cortex area was activated in all subjects. Conclusion: Our findings show that cortical activation can be induced by constant anodal tDCS and FES. They suggest that the above stimuli have the potential for facilitating brain plasticity and modulating neural excitability if applied as specific therapeutic interventions for brain injured patients.

Purpose: This study aimed to investigate the effects of exposure to endocrine disruptors, burnout, and social support from peers on premenstrual syndrome (PMS) in nurses. Methods: This descriptive correlational study was conducted among 122 nurses under the age of 49 working at a university hospital. The participants answered self-report questionnaires. The data were analyzed using the t-test, analysis of variance, Pearson or Spearman correlation coefficients, and hierarchical multiple regression in IBM SPSS version 23.0. Results: The mean age of the nurses was 28.9 years. Of these nurses, 49.2% were working in a general ward, 24.6% in the intensive care unit, 14.8% in the emergency room, and 11.4% in an outpatient department. The explanatory power of the model was 38.3%, and it was statistically significant (F=11.74, p≤.001). Exposure to endocrine disruptors (β=0.32, p<.001) was the most powerful variable affecting PMS, followed by burnout (β=0.27, p=.001), working in the intensive care unit or emergency room (β=0.22, p=.003), family history of PMS (β=0.19, p=.009), and support from coworkers (β=-0.15, p=.043). Conclusion: Based on these findings, it is necessary to develop an intervention program to reduce the symptoms of PMS. Additionally, further studies are needed to develop and evaluate measures to minimize exposure to endocrine disruptors and burnout in order to alleviate PMS among nurses.

Background: Gastrointestinal (GI) drugs are often co-prescribed with other medications to prevent GI complications. This study aimed to evaluate the prescribing pattern of potentially unnecessary GI drugs in patients with acute cystitis who were prescribed oral antibiotics and investigate the influencing factors affecting this. Methods: We identified female patients ≥20 years with acute cystitis who visited the outpatient clinic and were prescribed oral antibiotics between July and December by analyzing Health Insurance Review and Assessment Service (HIRA)-National Patients Sample (NPS)-2019 data. Patients with no prior history of GI disorders within 180 days prior to acute cystitis, excluding or including the date of diagnosis of acute cystitis, were selected (Group A and B). Multiple logistic regression analysis was performed to estimate the factors affecting the prescription of potentially unnecessary GI drugs. Results: A total of 1,544 in Group A and 552 patients in Group B were included for the final analysis. Potentially unnecessary GI drugs were prescribed in 1,176 patients in Group A (76.2%) and 231 patients in Group B (41.8%). Third generation cephalosporines and sulfonamides showed the lower odds ratio for prescribing GI drugs than penicillins. Prescribers from Urology clinics showed more than twice odds ratio for the prescription of GI drugs compared to prescribers from internal medicine clinics. Conclusion: The results of this study showed that potentially unnecessary GI drug prescriptions for patients with acute cystitis were high in South Korea. The positive risk factors affecting the prescription of unnecessary GIs were not patient-related factor but healthcare facility and prescriber-related factors.

Poria cocos is an edible and pharmaceutical mushroom with a long history of medicinal use in Korea. For the last 30 years, the domestic cultivated supply of Poria cocos has been unable to meet consumer demand, so Poria cocos is collected in mountainous areas and also imported from China. Thus, to increase the supply of Poria cocos, many artificial cultivation methods have been studied. In this study, Poria cocos is cultivated under different environmental conditions using plastic bags and the results compared. When cultivating Poria cocos at different temperatures (20, 25, 30 and $35^{\circ}C$) and using different numbers of plastic bag layers (1, 2), the most efficient cultivation conditions were a temperature of $25-30^{\circ}C$ and 2 plastic bag layers. The fastest growth was at $25-30^{\circ}C$, and the Poria cocos exhibited no weight change when cultivated using layers of plastic bags (1, 2).

Five cases of Diphyllobothrium latum infection were proved by collection of worms after treatment with bithionol, niclosamide or praziquantel, during 1975~1983. The patients were 4 males and one female aged 10~64 years residing in Seoul or Wando-gun, Chollanam-do, Korea. All of them remembered the history of eating several kinds of raw marine fish and 2 persons said they ate the raw mesh of perch, Lateolabrax japcnicus. Three amcnE them experienced abdominal pain, 2 natural discharge of a chain of segments, but none revealed any sign of anemia. The average egg size in stool varied $59~67{\times}41~48{\mu\textrm{m}}$ according to cases. The eggs were characterised by ovoid to elliptical shape, terminal operculum, and distinct abopercular protuberance. One naturally discharged segment (30cm) and 4 complete strobilae (320~680cm) with scolices obtained after treatments were examined. The morphological characters of proglottids such as rosette-form uterus with 3~6 loops, vaginal pore included in the cirrus sac, separated seminal vesicle from cirrus sac, etc. were all compatible with D. latum. These are the 7th~11th cases of D. latum infection proved by worms in Korea.

This paper reports 15 native valve endocarditis cases had surgical operation in the past 10 years at the department of Cardiovascular and Thoracic Surgery, Chonbuk National University Hospital. In this study, 10 cases out of 15 were in class I or II by the New York Heart Association functional classification. None of the cases had a history of taking addictive drugs. Five cases were congenital heart disease, three cases were rheumatic heart disease and two cases were degenerative heart disease. Thus 10 cases had the underlying disease. All cases had antibiotics treatment for 3 to 6 weeks before operation. In the culture test, only four cases were positive in the blood culture and one case was positive in the excised valve culture. Organisms on blood and valve culture were Streptococcus epidermis, Streptococcus viridans, Staphylococcus aureus and Staphylococcus epidermidis. In the 10 cases without ventricular septal defect, the aortic valve was involved in four, mitral in four, both in two and involved valves in the 5 cases with ventricular septal defect were tricuspid in three, pulmonic in two. Eight cases had operation because they showed moderate congestive heart failure due to valvular insufficiency and vegetation with or without embolism. Seven cases had operation because they showed persistent or progressive congestive heart failure and/or uncontrolled infection. Five cases with ventricular septal defect underwent the closure of ventricular septal defect, vegetectomy and leaflet excision of the affected valves without valve replacement. In the cases without ventricular septal defect, the affected valves were replaced with St. Jude mechanical prosthesis. Postoperative complications were recurrent endocarditis in two, embolism in one, allergic vasculitis in two, spleen rupture in one and postpericardiotomy syndrome in one. At the first postoperative day, one case died of cerebral embolism. At the 11th postoperative month, one case died of recurrent endocarditis and paravalvular leakage in spite of a couple of aortic valve replacement. In the survived cases[13 cases in this study , all cases but one became class I or II by the New York Heart Association functional classification.

Type 1 diabetes mellitus commonly occurs in childhood and adolescence, although the prevalence of type 2 diabetes mellitus in these age groups is now being increased in the western world and Korea. Diabetic nephropathy developing in 15-25% of subjects with type 1 diabetes mellitus and in similar or higher percentage of type 2 diabetes mellitus patients is the leading cause of end-stage renal disease worldwide. Although prepubertal diabetic duration may contribute less to the development of microvascular complications than pubertal and postpubertal duration, diabetic nephropathy in susceptible patients almost certainly begins soon after disease onset and may accelerate during adolescence, leading to microalbuminuria or incipient DN. Type 1 diabetes is commonly associated with a period of hyperfiltration followed by the development of persistent microalbuminuria after as little as 7-10 years of type 1 diabetes. Microalbuminuria is associated with pathologic lesions that are so advanced as to overlap with those seen in patients with overt proteinuria and declining kidney function, therefore, microalbuminuria currently considered the best clinical indicator of overt diabetic nephropathy risk. This review covers the natural history and renal manifestations of diabetic nephropathy in children and adolescents.

The pediatrics has other diagnosis and treatment compared with an adult. It is therefore, the children have different pathogenesis, pathology from adult's. The special feature of the children is two. Firstly, children are the body of the pure Yang[純陽之體], which means the growth and development of them are very fast. Secondly, they have weak muscle, skeletal and digestive function. So we must consider health-preserving method in different physiology and pathology aspects of the children. The children have weak digestive functions, so they should be careful to avoid eating greasy food and overeating. They must eat the nourishing Eum[滋陰] food. The children should wear thin clothes as possible. If the children wear clothes so thick, it promote the Yang (陽), so the Eum(陰) is hurted. The children are to be lack of Eum[陰不足], so they need to grow and raise the Eum(陰) in this way which the lower body is cool. Sleep is important ways to generate Eum Essence[陰精]. So the children should take a bed as change of the season. Children's muscles and skeleton are growing so incomplete that they are hard to handle Wind-Cold pathogen[風寒邪]. Therefore, the children should be training vital Essence and Gi(氣) with appropriate exercise. We should be careful treatment the Hwayeoljeung(火熱證) with purgation[瀉下] - bitter in taste and cold in nature[苦寒藥], aromatic herb[芳香性藥物], sudorific herb[發汗藥] In addition, child has weak digestive function, so doctor should not use a lot of nourishment[滋補].

Background: Low-dose oral contraceptives (OC) were approved by the Japanese Ministry of Health, Labor and Welfare in 1999, yet despite their contraceptive and non-contraceptive health benefits, only 5% of the target population use them. Fear of increased cancer risk, particularly breast cancer, is one reason for this. Due to low OC uptake and low screening participation, a paucity of data is available on the risk of OC use and breast cancer in Japanese women. The present study investigated OC use and breast cancer risk, as well as menstrual, reproductive and family factors. Materials and Methods: This was a clinic-based case-control study of women aged 20-69yrs who had undergone breast screening between January 2007 and December 2013 in central Tokyo. In all, 28.8% of the participants had experience with OC use. Cases were 155 women with a pathologically confirmed diagnosis of breast cancer. Controls were the remaining 12,333 women. Results: Increased age was a significant risk factor for breast cancer (p<0.001). A lower risk was found in premenopausal women presently taking OC compared to never users (OR 0.45; 95% CI 0.22-0.90) after adjusting for age, parity and breast feeding, and a family history of breast cancer. Conclusions: Increased age rather than OC use had a greater effect on breast cancer risk. This risk may be decreased in premenopausal women with OC use, but further long-term prospective studies are necessary.
