Ataxia is one of the most serious neurological symptoms in elderly The clarification of the related anatomical structures are necessary for the understanding of pathophysiologic mechanisms of ataxia. We have recently experienced a case of thalamic infarct in the territory of thalamogeniculate artery. The localization of lesion was based on CT and MR imaging. At first time, right hemiparesis and ataxia were prominent. Hemiparesis was transient but ataxia had been persistent for several months. It has been suspected that thalamus could be the part of neural circuits in balancing. Our case support this suggestion clinically. Based on clinical observations, a plausible extrapolation can be made to thalamic ataxia. It maybe related with dysfunction of dentatorubrothalamic and corticopontine pathway. Thus our case led us to conclude that thalamus could be engaged in balance control of human body.

We conducted this cohort analytic study to determine whether women with unexplained elevations of maternal serum hCG at 15-18 weeks' gestation are at increased risk for pregnancy complications and adverse perinatal outcomes. The inclusion criteria were a singleton gestation, a confirmed gestational age, and an hCG level greater than 2.0 multiples of the median (MoM). The exclusion criteria were fetal anomalies, an abnormal karyotype, molar pregnancy, and an MSAFP level greater than 2.5 multiples of the median (MoM). A group of randomly selected women with hCG levels under 2.0 MoM served as controls. Patients with elevated levels of hCG had a significantly higher risk for PIH (17.9% versus 4.5%; P <.05) and preterm delivery (17.9% versus 3.5%; P<, 05) than control. But no significant differences were observed in the incidence of intrauterine growth restriction and low birth weight and in the newborn weight. We suggested that pregnancies with unexplained elevated hCG levels should be regarded as high-risk pregnancies. And these patients require careful monitoring with adequate obstetric management.

PURPOSE: In this study self-efficacy, emotional labor, pediatric nurse-parent partnership and job stress of pediatric nurses were examined. Factors affecting job stress of pediatric nurses were also investigated. METHODS: The study was done between June and September 2014, with a convenience sample of 145 nurses from 3 advanced general hospitals, 5 general hospitals and 2 children's hospitals. Research data were collected via questionnaires and analysed using SPSS version 18.0. RESULTS: Average levels of self-efficacy, emotional labor and job stress were similar to other general nurses and the average level of pediatric nurse-parent partnership was also similar to other pediatric nurses. Job stress of pediatric nurses showed a positive correlation with emotional labor and negative correlations with self-efficacy and pediatric nurse-parent partnership. The most significant factor affecting job stress in pediatric nurses was emotional labor (beta=0.372, p<.001). The combination of emotional labor, pediatric nurse-parent partnership and self-efficacy accounted for 25.4% of job stress in pediatric nurses. CONCLUSION: These results suggest that nursing management strategies to decrease emotional labor and improve pediatric nurse-parent partnerships and self-efficacy are critical to decrease job stress for pediatric nurses. Continued development of nursing management interventions to decrease job stress in pediatric nurses is suggested.

4.Nursery Teachers' Knowledge, Attitude and Performance Ability in CardioPulmonary Resuscitation.
Child Health Nursing Research 2014;20(4):304-313
PURPOSE: This study was done to identify the level of knowledge, attitude and performance ability in CardioPulmonary Resuscitation (CPR) and provided data for the development of an education program to improve CPR performance ability of nursery teachers. METHODS: The participants were 220 nursery teachers working in daycare centers in A city located in G province. Data were collected during July, 2013. RESULTS: The mean scores were 45.88 of 100 for knowledge, 3.69 of 5 for attitude, 2.65 of 5 for performance ability. There were significant differences in knowledge and performance ability according to education experience. There were positive correlations between knowledge and performance ability, and between attitude and performance ability. Factors affecting CPR performance ability were knowledge (beta=.133), attitude (beta=.327), and education in CPR (beta=.343). These factors explained 29.4% of the variance in CPR performance ability. CONCLUSION: Results indicate that nursery teachers' knowledge, attitude and CPR performance ability were not sufficient enough to perform accurate CPR in an emergency. Therefore, to improve performance ability of nursery teachers to carry out CPR in a cardiac arrest emergency of a child, educational strategies that focus on increasing knowledge and attitude need to be developed.

5.Effect of Visiting and a Smartphone Application Based Infection Prevention Education Program for Child Care Teachers: A Non-Randomized Controlled Trial.
Journal of Korean Academy of Nursing 2017;47(6):744-755
PURPOSE: This study was performed to develop an infection prevention education program for child care teachers and to verify its effects. METHODS: The study was conducted using a nonequivalent control group with a pretest-posttest design. Four private daycare centers (2 centers per city) that were alike in terms of the number of children by age, number of child care teachers, and child care environment were chosen. Participants were assigned to the experimental group (n=20) or control group (n=20). As a part of the program, visiting education (90 min) was provided in the 1st week, and smartphone application education (10 min) was provided thrice a week, in the 2nd and 3rd weeks. RESULTS: Child care teachers' self-efficacy for infection prevention revealed a significant interaction effect between the group and time of measurement (F=21.62, p < .001). In terms of infection prevention behavior, a significant difference was observed between the experimental and control groups (z=−5.36, p < .001). CONCLUSION: The program implemented in this study was effective in improving the infection prevention self-efficacy and infection prevention behavior of child care teachers. Thus, this program may be effective in enhancing their infection control.

We described 2 patients with Marchiafava-Bignami disease, a neurological disorder associated with chronic alcohol consumption. Patient 1 expressed general weakness and confusion, while patient 2 expressed dysphagia and seizures. Lesions involving the corpus callosum were identified with T2 weighted MR imaging in which there was a hyperintensity in the splenium of patient 1 and in the entire corpus callosum of patient 2. While the conditions of both patients were improved by with nutritional support, they were left with cognitive impairment.

We report a case of exogastric schwannoma of the stomach in 41-years-old male patient with papable mass in left upper abdomen. Upper GI series revealed extrinsic compression on the greater curvature of the stomach. CT scan showed a low density mass attached to greater curvature of the stomach with inhomogeneous contrast nhancement in the mass lesion. The mass was removed by surgery, and confirmed pathologically as schwannoma arising from the stomach.

BACKGROUND: The diagnostic significance of ECG ergonovine test and the incidence of vasospastic angina in patients with chest pain are still uncertain. METHODS: From May 1998 to June 1999, 133 consecutive patients with chest pain were admitted for diagnostic coronary angiography. ECG ergonovine provocation tests were performed in 64 patients who have a clinical history suggesting vasospatic angina, including 27 of 28 patients with vasospastic angina documented electrocardiographically, or who's coronary angiographic findings could not be explained by their clinical history. Ergonovine was administered intravenously in incremental dose of 0.05, 0.1, 0.2, 0.3, 0.4 mg up to total cumulative dosage of 1.0mg during coronary angiography(41 cases), in the exercise laboratory(21 cases) or both(2 cases). RESULTS: Of 133 patients with chest pain, vasospastic angina was documented in 32(24%), unstable angina in 52(34%), stable angina in 10(8%), and others in 39(29%). Angiography demonstrated coronary spasm in 4 additional patients as well as 22 patients with vasospastic angina documented electrocardiographically, but ergonovine tests in the exercise laboratory showed positive response in 5 of 6 patients with vasospastic angina documented. Among the 25 patients with coronary spasm proved angiographically during ergonovine test, ECG findings at the time of coronary spasm were ST segment elevation in 21(84%), depression in 1(4%) and no change in 3(12%) patients, who had branch vessel spasm, 3 vessel spasm or incomplete spasm on coronary angiogram. Of the 31 patients with vasospastic angina who underwent ergonovine tests, positive response occurred in 24(77%) after a cumulative dose of < or = 0.4mg and in additional 3(10%) after the higher dose of >0.4mg. However the other 4(13%) had no ECG changes even after the higher dose(>0.4mg) of ergonovine. CONCLUSION: This results suggest that vasospastic angina appear to be a common cause of chest pain, and ECG ergonovine test with high dose can improve diagnostic sensitivity but cannot detect some patients with vasospastic angina.

OBJECTIVE: The aim of this study is to comparing the prevalence and correlationships between human papillomavirus (HPV) and Chlamydia trachomatis (CT) infection in cervical samples among women with abnormal cervical cytology. METHODS: This study was included three hundred seventy four patients with a abnormal liquid-based cytology in Dankook University hospital. All of them underwent HPV DNA test and CT analysis with polymerase chain reaction. All patients also went through colposcopic directed cervical biopsies or Loop Electrosurgical Excision Procedure, conization. The histo-pathologic results were classified as normal, cervical intraepithelial neoplasia (CIN) 1, CIN 2, CIN 3 and carcinoma in situ (CIS). RESULTS: Abnormal liquid-based cytology patients were pathologically proven to have CIN. Among 374 patients, the number of within normal limits (chronic cervicitis) and koilocytosis was 186 cases (49.7%), CIN 1, 64 cases (17.1%), CIN 2, 16 cases (4.3%) CIN 3, 55 cases (14.7%), and CIS, 53 cases (14.2%). HPV DNA positive patients were 235 cases and HPV DNA negative patients were 139 cases. The impact of CT infection seems not to interfere with the development or even the progression of CIN. Thirty one patients had positive infection of CT (8.3%) and 343 patients were negative infection of CT (91.7%). Both HPV and CT positive infected patients were 25 cases (6.7%) in abnormal cytologic women. The correlation between HPV and CT DNA positive among women with abnormal cytology was statistically significant. (P=0.022) CONCLUSION: This study suggests that CT infection is associated with HPV infection, but the clinical significance of the association between CT and HPV infection remains to be elucidated.

PURPOSE: This study was performed to evaluate MR signal intensity(SI) of calcification and to assess the capability of MRI in detection of various intracranial calcifications. MATERIALS AND METHODS: The MR findings and ROI value of experimental model of calcium carbonate suspension according to each concentration (20, 35, 50%) and diameter (1-10 mm) and hydroxyapatite suspension according to each concentration (10, 20, 30, 40, 50%) were analyzed. A specimen of calcification in cranio-pharyngioma was analyzed for its composition by XRD(X-ray diffractometer) and ICP(inductively coupled plasma) methods. MRI of 34 patients with intracranial calcifications were retrospectively analyzed for signal intensity of the calcification and its capability to detect calcifications according to size, location, and contrast with adjacent lesion. RESULTS: The calcium carbonate phantom with larger diameter and low concentration showed lower signal intensity on T2 than TlWl. Hydroxyapatite phantom showed high signal intensity in 10-30% concentration and low signal intensity in 40-50% concentration on T1 weighted image. The 5 cases of 34 intracranial calcifications showed high signal intensity on T1 weighted image. The capability of MRI in the detection of intracranial calcifications decreased in the circumstances such as small size(<2.5mm) and intraventricular location. Although the size of calcification was small, the detection was easy in the good contrast with adjacent lesion. However, the detection of the small sized calcification was easy if the contrast with adjacent lesion was good. CONCLUSION: lntracranial calcification shows generally low signal intensity on T1 and T2 weighted image with the exception of occasional high SI on TlWl. Detection of intracranial calcification in MRI is affected by its composition, size, location, and contrast with adjcent lesion.
