PURPOSE: The ictal perfusion patterns of cerebellum and basal ganglia have not been systematically investigated in patients with temporal lobe epilepsy (TLE). Their ictal perfusion patterns were analyzed in relation with temporal lobe and frontal lobe hyperperfusion during TLE seizures using SPECT subtraction. MATERIALS AND METHODS: Thirty-three TLE patients had interictal and ictal SPECT, video-EEG monitoring, SPGR MRI, and SPECT subtraction with MRI co-registration. RESULTS: The vermian cerebellar hyperperfusion (CH) was observed in 26 patients (78.8%) and hemispheric CH in 25 (75.8%). Compared to the side of epileptogenic temporal lobe, there were seven ipsilateral hemispheric CH (28.0%), fifteen contralateral hemispheric CH (60.0%) and three bilateral hemispheric CH (12.0%). CH was more frequently observed in patients with additional frontal hyperperfusion (14/15, 93.3%) than in patients without frontal hyperperfusion (11/18, 61.1%). The basal ganglia hyperperfusion (BGH) was seen in 11 of the 15 patients with frontotemporal hyperperfusion (73.3%) and 11 of the 18 with temporal hyperperfusion only (61.1%). In 17 patients with unilateral BGH, contralateral CH to the BGH was observed in 14 (82.5%) and ipsilateral CH to BGH in 2 (11.8%) and bilateral CH in 1 (5.9%). CONCLUSION: The cerebellar hyperperfusion and basal ganglia hyperperfusion during seizures of TLE can be contralateral, ipsilateral or bilateral to the seizure focus. The presence of additional frontal or basal ganglia hyperperfusion was more frequently associated with contralateral hemispheric CH to their sides. However, temporal lobe hyperperfusion appears to be related with both ipsilateral and contralateral hemispheric CH.

BACKGROUND: This study investigated the efficacy and safety of combined subacromial and intravenous patient-controlled analgesia for control of postoperative pain after arthroscopic rotator cuff repair. METHODS: Between May 2012 and August 2014, 60 patients who underwent arthroscopic rotator cuff repair with acromioplasty and received patient-controlled analgesia were studied prospectively. Cases were divided into 2 groups: combined subacromial and intravenous infusion group (group A, 30 cases) and solitary intravenous infusion group (group B, 30 cases). The visual analogue scale was used to record the patient's level of pain every 12 hours during postoperative 72 hours and the following 48 hours after the suspension of patient-controlled analgesia. RESULTS: The mean preoperative visual analogue scale score was 7.8 in group A and 7.6 in group B, and the immediate postoperative visual analogue scale score was 7.9 and 8.1 for each group. At postoperative time (From 12 hours to 72 hours after operation), the scores of combined subacromial and intravenous infusion were significantly lower than those of solitary intravenous infusion. Significant difference in the frequency of supplemental analgesic injections was observed between group A and group B (p=0.008). However, no significant difference in complication rate was observed between the two groups (p=0.562). CONCLUSIONS: Combined subacromial and intravenous patient-controlled analgesia after arthroscopic rotator cuff repair is more effective than solitary intravenous infusion without significantly increasing complications. Therefore, combined subacromial and intravenous patient-controlled analgesia could be a effective pain control method.

Korean Journal of Women Health Nursing 2002;8(3):424-434
Background & PURPOSE:Since the 1970's the rate of breast-feeding has decreased significantly. The Korean National Institute of Health reported that the rate of breastfeeding was 68.9% in 1982 and 14.1% in 1997. There are many influencing factors including: the lack of education and information on breast feeding, lack of faith in breast feeding, increment of the rate of working, lack of encouragement by supporters in difficult situations, and nurses' low level of knowledge about breast feeding. Such a lack of knowledge and support of breast-feeding at home by family members create another dilemma to the problem of breast-feeding. If problems arise and family members are unable to provide assistance due to the deficiency of knowledge, mothers show a tendency to abandon breast-feeding. The purpose of this research is to find out the rate of breast-feeding practice by time sequence of 1 week, 6 weeks and 12 weeks after birth and influencing factors on breast-feeding practice centered on the postpartal women who were 3discharged from one hospital, which is located in Seoul and provides simple breast-feeding education and continuous postnatal telephone consultation. Methodology: The subjects of this research were 54 women who gave birth in a hospital located in Seoul from 1 March 2000 to 31 April 2000. After birth the subjects were educated individually about breast-feeding and telephone consultations were conducted. On the 1st week, 6th week, and 12th week, the subjects were surveyed about their breast-feeding practice rates and methods by telephone. Results: 1) Complete breast-feeding rate: Within one week after birth, the subjects showed 64.2% complete breast-feeding rate. Within 6 weeks, 39.6%, and 12 weeks, 34.1%. 2)Partial breast-feeding rate: Within one week after birth, the subjects showed 32.1% partial breast-feeding rate. Within 6 weeks, 39.6%, and 12 weeks 15.1%. 3)Complete bottle-feeding rate Within one week after birth, the subjects showed 1.9% complete bottle-feeding rate. Within 6 weeks of giving birth 15.1%, and 12 weeks 17.0%. These results show that individual education about breast-feeding and continuous postnatal telephone consultation influenced on the practice of breast-feeding. On considering the reality of the hospital situation in which nurses could not operate education program due to the work-load, it is necessary to find out selectively those mothers who are unable to breast feed and provide education individually and continuous support by telephone follow up. Futhermore, the active role of lactation nurse specialist and their efficient management of breast-feeding for the successful practice is required.

BACKGROUND: The aim of the present study was to determine the correlation between the amount of pain reduction after local anesthetic injection into the subacromial space preoperatively and clinical outcome after arthroscopic rotator cuff repair. METHODS: A total of 127 patients who underwent arthroscopic rotator cuff repair and followed up at least 1 year were analyzed retrospectively. Preoperatively, a visual analogue scale (VAS) for pain was measured in all patients before and after the ultrasound guided impingement test. The participants were divied into four groups according to pain reduntion ater impingement test (Group A: >75%, Group B: 50%–75%, Group C: 25%–50%, Group D: <25%). VAS for pain, shoulder range of motion, shoulder isometric strength, ASES score were evaluated preoperatively and at 3, 6, 9, and 12 months postoperatively. RESULTS: After surgery, the amount of pain reduction shows significantly at 3, 6 months in Groups A, B as compared to Groups C, D (p<0.05). Among the range of motion of shoulder joint, forward flexion was significantly improved in Group A at 3 months (p<0.05). The ASES score significantly improved at 3, 6 months in Groups A, B as compared to Group C, D (p<0.05). CONCLUSIONS: Preoperative degree of pain reduction after impingement test correlates with the improvement of pain after arthroscopic rotator cuff repair, especially in the early phase. Therefore, the impingement test could be effectively used.

5.Difference in Healthcare Utilization for Percutaneous Transluminal Coronary Angioplasty Inpatients by Insurance Types: Propensity Score Matching Analysis.
Health Policy and Management 2015;25(1):3-10
BACKGROUND: Previous studies showed differences in healthcare utilization among insurance types. This study aimed to analyze the difference in healthcare utilization for percutaneous transluminal coronary angioplasty inpatients by insurance types after controlling factors affecting healthcare utilization using propensity score matching (PSM). METHODS: The 2011 national inpatient sample based on health insurance claims data was used for analysis. PSM was used to control factors influencing healthcare utilization except insurance types. Length of stay and total charges were used as healthcare utilization variables. Patients were divided into National Health Insurance (NHI) and Medical Aid (MA) patients. Factors representing inpatients (gender, age, admission sources, and Elixhauser comorbidity index) and hospitals (number of doctors, number of beds, and location of hospitals) were used as covariates in PSM. RESULTS: Tertiary hospitals didn't show significant difference in length of stay and total charges after PSM between two insurance types. However, MA patients showed significantly longer length of stay than that of NHI patients after PSM in general hospitals. Multivariate regression analysis provided that admission sources, Elixhauser comorbidity index, insurance types, number of doctors, and location of hospitals (province) had significant influences on the length of stay in general hospitals. CONCLUSION: Study results provided evidences that healthcare utilization was differed by insurance types in general hospitals. Health policy makers will need to prepare interventions to influence the healthcare utilization differences between insurance types.

Epidermolytic keratosis palmaris is a rare disease which shows clinical findings of Unna Thost keratoderma and histopathologic of epidermolytic hyperkeratosis. We report herein a case of epidermolytic keratosis palmaris et plantaris in a 16-month-old female baby. Light microscopy shows marked hyperkeratosis, large irregular keratohyalin granules, and large clear spaces in the granular and upper spinous layers. Eletron microscopic findings shows that the clear spaces are areas of cytoplasm filled with a fibrillar material and cellular organelles. Abnormal clumping of tonofilament and keratohyalin is also present.

Urinary cytology has become an essential element in the diagnosis and management of transitional cell carcinoma(TCC) of the urinary tract. It has the advantage of being noninvasive, inexpensive, and easily accessible. Besides that it can even detect malignancy when unsuspected at cystoscopy. We report a retrospective review of urine cytology in the diagnosis of 83 TCC cases that underwent 295 cytologic evaluation. All patients had biopsy-proven TCC of the bladder, ureter and renal pelvis. The overall inci- dence of the positive cytology cases was 66.2%. To define the cytologic features of tumor cells, we tried to use three cytologic gradings such as "grade 1", "grade 2", and "grade 3" according to the cytologic degree of anaplastic neoplastic cells. These cytologic gades of TCC were relatively well correlated with the histologic grade and tumor invasiveness. This result suggests that the recognition of characteristic cellular features of TCC can suspect the histologic grade and tumor stage. The false negative TCC cases were 78.9%. They showed severe inflammatory or bloody background and a few neoplastic cells. Therefore, a cautious approach for accurate interpretation, personal experience, and proper fixation and processing could expand the role of urinary cytology.

9.A Review of Healthcare Provider Payment System in Korea
Health Policy and Management 2023;33(4):379-388
This study aims to propose the implementation of innovative payment models in Korea in order to promote the financial sustainability of the national health insurance system by reviewing the current status of the payment system in Korea and examining other countries’ experiences with various innovative payment models. Korea primarily uses a fee-for-service payment system and additionally uses various payment systems such as case payment, per diem, and pay-for-performance. However, each payment system has its limitations. Many OECD (Organization for Economic Cooperation and Development) countries have pointed out the limitations of existing payment systems and have been attempting various innovative payment models (e.g., add-on payment, bundled payment, and population-based payment). Therefore, it is essential for Korea to consider innovative payment models, such as a mixed payment model that takes into account the strengths and weaknesses of each payment system, and to design and pilot these models.This process requires stakeholders to work together to build a social consensus on the implementation of innovative payment systems and to refine legal and systematic aspects, develop an integrated health information system, and establish dedicated organizations and committees. These efforts towards innovative payment models will contribute to developing a sustainable health insurance system that ensures the public’s health and well-being in Korea.

PURPOSE: The purpose of this study was to elucidate nursing performance to superior's ethical leadership as perceived by nurses and the mediating effect of faith in supervisor. METHODS: For this study a descriptive survey design was used. Participants were 258 nurses who worked in general hospital and completed the self-report questionnaire. Data were collected from May 17 to May 31, 2017 and were analyzed using independent t-test, ANOVA, Scheffé test, and Path analysis with SPSS 22.0 and AMOS 21.0. RESULTS: Superior's ethical leadership as perceived by the nurses and faith in the supervisor were significant variables predicting the level of nursing performance and accounted for 48.1% of the variance. Faith in the supervisor as a mediator was found to have a partial mediating effect. CONCLUSION: In order to improve the nurses' performance, it is important to establish a work environment so that hospital nurses can perform their work with faith in their supervisors, as well as having superiors who are ethical leaders.
