Recently elevated plasma homocysteine concentration is considered an independent risk factor for atherosclerosis and thrombosis with coronary artery disease. Folate and vitamin $B_{12}$ are cofactors and closely related with metabolism of homocysteine. The purpose of this study is to evaluate the correlation between homocysteine and folate and vitamin $B_{12}$ in patients with ischemic heart disease. Twenty-six patients, in whom coronary angiographic finding revealed more than $50\%$ of stenosis at least in one coronary vessel were enrolled as the patient group, and thirty subjects, in whom angiographic finding revealed in not significant stenosis, but complained of chest pain, were selected as the control group. Fasting venous blood was obtained and measured the concentration of plasma total homocysteine, folate and vitamin $B_{12}$ by high performance liquid chromatography and fluorescence detection method. We examined the correlation between homocysteine and folate and/or vitamin $B_{12}$ in the control group and the patient group, respectively. Compared with the control group, the patient group had relatively higher plasma total homocysteine concentration ($10.7\pm4.2\;vs\;9.6\pm3.5$ umol/L), but showed no significant difference. Folate and vitamin $B_{12}$ concentration are low in the patient group, but showed no significant difference between patient and control group. Plasma total homocysteine concentration showed negative correlation with folate and vitamin $B_{12}$ in both the control group and the patient group, and showed significantly negative correlation in patient group {r = -0.550 (p < 0.01) vs r = -0.609 (p < 0.01)}. We knew that the plasma total homocysteine concentration were relatively elevated in patient group compared with the control group. Because plasma total homocysteine concentrations are closely negative correlated with folate and vitamin $B_{12}$ in the patient group, folate and vitamin $B_{12}$ supplement can lower the mortality and morbidity of ischemic heart disease.

Purpose: The purpose of this study was to evaluate the effects of preoperative PCA (Patient-Controlled Analgesia) education on pain, patient attitude, and patient satisfaction in surgical patients. Methods: The study was a quasi-experimental research design. The participants were 54 patients who were admitted for surgery at I hospital in G city, Korea. Of the 54 patients, 26 were assigned to the experimental group and the rest to the control group. The PCA education was provided in the nurses' station, individually to patients in the experimental group the day before their operation. Multimedia and brochure, and a real PCA model were used. The control group received only verbal education about PCA. Results: The postoperative pain scores were significantly different for lapse of time in the experimental group compare to the control group. Patient attitude toward using pain medicine was significantly more positive in the experimental group than in the control group. The postoperative patient satisfaction with pain management was significantly higher in the experimental group than in the control group. Conclusion: The study findings indicate that preoperative PCA education could be an effective nursing intervention for pain management of surgical patients.

Backgrounds: Patient counseling has been forced since June. 19, 2014. Prior to this, there was no study to try to standardize medication counseling to improve quality. Purpose: This study was to investigate satisfaction level and comprehension level between the pharmacist group and the patient group about standardized medication counseling sheet. Methods: Questionnaires to assess standardized patient counseling sheet were posted at online survey software (Qualtrics) to pharmacists who worked at community pharmacy and patients who had visited community pharmacy before. Results: Three hundred thirty five patients and three hundred nineteen pharmacists were responded to the questionnaire (Response rate: 72.9%). More than half of each group were satisfied with standardized medication counseling sheets 'for the general public', 'for the pregnant women and nursing mothers', 'for the chronic patient', and 'for the aged' and patient group were more satisfied than pharmacist group. Similarly, more than half of each group comprehended with the medication counseling sheets 'for the general public', 'for the pregnant women and nursing mothers', 'for the chronic patient', and 'for the aged'. Patient group tended to expect longer patient counseling time per one drug than pharmacist group. Also, the majority of both groups wanted to provide standardized medication counseling sheets constantly and extend for all drugs. Conclusion: Both groups were satisfied and comprehended standardized medication counseling sheets, and agreed to expand standardized medication counseling sheets to all drugs. So, it is necessary to build the standardized medication counseling of all drugs.

Purpose: To examine the degree of recognition regarding the concept of patient safety, as perceived by the patient, using a focus group discussion. Methods: A focus group discussion was conducted with a patient group comprising seven patients. Results: When the participants heard the term "patient safety" they seemed to understand it to be related to the hospital environment or satisfaction with the overall hospitalization experience. The participants emphasized communication between the medical staff and the patients in relation to the explanation of treatments, as well as the provision of information regarding prevention, experience, and the treatment of incidents with patient safety. They agreed on the need for indicators reported by patients. However, they emphasized that additional items and a questionnaire method that considers the patients' point of view are needed. Conclusion: It is necessary to establish and implement various strategies that can raise the awareness of patient safety using patient safety indicators and increase participation in patient safety activities.

Purpose: To evaluate the usefulness of fractal analysis for diagnosis of periodontitis. Materials and Methods : Each 30 cases of periapical films of male mandibular molar were selected in normal group and patient group which had complete furcation involvement. They were digitized at 300 dpi, 256 gray levels and saved with gif format. Rectangular ROIs (10×20 pixel) were selected at furcation, interdental crest, and interdental middle 1/3 area. Fractal dimensions were calculated three times at each area by mass radius method and were determined using a mean of three measurements. We compared fractal dimensions at furcation and interdental crest area of normal group with those of patient group. And then we compared ratio of fractal dimensions at furcation area, interdental crest area to interdental middle 1/3 area. Results: Fractal dimension at interdental crest area of normal group was 1.979±0.018 and that of patient group 1.971±0.012 (p>0.05). Fractal dimension at furcation area of normal group was 1.986±0.024 and that of patient group 1.974±0.015 (p<0.05). The ratio of fractal dimension at interdental crest area to interdental middle 1/3 of normal group was 1.003±0.015 and that of patient group 0.993±0.018 (p<0.05). The ratio of fractal dimension at furcation area to interdental middle 1/3 of normal group was 1.006±0.018 and that of patient group 0.994±0.018 (p<0.05). Conclusion : The ratio of fractal dimension at interdental crest and furcation area to interdental middle 1/3 area showed a statistically significant difference between normal and patient group. In conclusion, it is thought that fractal analysis might be useful for the diagnosis of periodontitis.

The author analysed tomographic and cephalometric radiographs of 82 temporomandibular joints from 41 symptomatic patients and 40 temporomandibular joints from 20 asymptomatic young adults. The results were as follows; 1. The mean condylar angulation in control group and patient group was 21.72±6.48° 20.13±9.14° respectively and there was no significant difference between two groups. 2. The mean depth of cut was 6.63±0.38㎝ in control group and 6.57±0.46㎝ in patient group. 3. Mean height and width of condylar head were 6.66±1.83㎜, 12.42±0.49㎜ in control group and 6.22±1.36㎜, 11.93±l.92㎜ in patient group. 4. The mean height of articular fossa was 10.20±2.04㎜ in control group and 9.89±1.98㎜ in patient group. The mean width of articular fossa was 21.08±2.08㎜ in control group and 21.24±3.03㎜ in patient group. 5. In centric occlusion the superior joint space was largest (4.15±0.93㎜), followed by the posterior joint space (2.99±0.97㎜) and the anterior joint space (2.70±0.73㎜) in control group. The superior joint space (3.47±1.31㎜) and posterior joint space (3.47±7.07㎜) were same in patient group. There was significant difference in left superior joint spaces between two groups (p<0.05). 6. The condylar position in articular fossa was displaced anteroinferiorly (0.99±3.65㎜ anteriorly, 1.75±1.01㎜ inferiorly) in control group and posteroinferiorly (3.20±4.69㎜ posteriorly, 1.25±1.87㎜ inferiorly) in patient group with 1 inch opening. In maximum opening, it was displaced anteroinferiorly (6.09±3.55㎜ anteriorly, 1.38±2.47㎜ inferiorly) in control group and anteroinferiorly (1.70±5.96㎜ anteriorly, 1.37±1.85㎜ inferiorly) in patient group.

Open reduction and rigid internal fixation is the most popular treatment method for maxillofacial fracture patients, and it is unevitable that postoperative pain can be developed. Many surgeons including oral & maxillofacial surgeons have made constant efforts to decrease postoperative pain. This study is a comparison of postoperative analgesia and intramuscular analgesia in patients with mandibular fractures. In this study, twenty-one patients (Experimental group) were randomly selected and they were injected with IV patient-controlled analgesia (PCA; Walkmed$^{(R)}$, USA). For control group another twenty-one patients were injected with intramusclar non-steroid anti-inflammatory drugs (Rheoma$^{(R)}$, Samsung Pharm. Co.). And then, we measured visual analogue scale (VAS) scores from first postoperative day to second day at regular time interval. The following results were uptained; 1. In patient group who with open reduction and rigid internal fixation, there was significant difference of postoperative analgesic effect during the first postoperative day(p<0.05). 2. In patient group with over 90 minutes surgery time, there was significant difference of postoperative analgesic effect during the first and second postoperative day when compared between experimental group and control group(p<0.05). 3. In patient group with less than 90 minutes surgery time, there was no significant difference of postoperative analgesic effect during the first and second postoperative day when compared between experimental group and control group(p>0.05). 4. In patient group with surgery of open reduction using rigid internal fixation at single fractured site, there was no significant difference of postoperative analgesic effect during the first and second postoperative day when compared between experimental group and control group(p>0.05). 5. In patient group with surgery at two fractured sites, there was significant difference of postoperative analgesic effect during the first postoperative day when compared between experimental group and control group(p<0.05). As mentioned above, it suggest that patient-controlled analgesia is more effective for postoperative pain relief than intramuscular injection in patients with rigid internal fixation by open reduction after mandibular fracture occurred. Especially, it is considered that in patient with more than 90 minutes surgery time or in cases with multiple fractured sites had more effective results with PCA therapy than conventional intramuscular analgesics.

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.

The purpose of this study is to help the care of patient and to his family through comparison of the level of anxiety which between the family of admitted patient and the family without in patient, and to his family through comparison of the level of anxiety which between the family of admitted patient and the family without inpatient and exclude the factors which raised the level of anxiety in them. The experimental group in this study were samples of 200 patient's family selected by random sampling in H. University hospital located in Seoul (Department of patient were internal medicine, surgery, pediatrics and neuropsychiatry). The control group were samples of 70 family without inpatient selected by random sampling in Seoul. The data were collected through STAI (State-Trait Anxiety Inventory) by Spielberger (1970) for measurement to level of state and trait anxiety from April 1st to April 15th in 1982. The contents of data analysis by EDPS included the difference of level of anxiety between experimental and control group, correlationship between general characteristics of experimental group and level of anxiety, and correlation of trait and state anxiety in experimental group. The Findings of this study were as follows: 1) Level of anxiety of experimental group is higher than control group. 2) In the correlation between general characteristics and level of anxiety of experimental group, there were no significant difference which revealed in correlation with age of family member, family life cycle, marital status, the relation between patient and family member, the degree of symptom, number of admission, admission or nonadmission of medical insurance, number of family member, and division of disease to level of anxiety However, according to the sex of family member, hospitalization period, a monthly income of family, the degree of confidence toward medical team, religion of family, academic background of family, a tendency of significant differences to level of anxiety were seen. To put them in the concrete, they were as follow; a) Level of. anxiety on female family member is higher than male in experimental group. b) Admission period of patient is positively related to the level of anxiety of patient's family. c) The degree of confidence of patient's family toward medical team is in inverse proportion to the level of anxiety. d) A monthly income of patient's family is in inverse proportion to the level of anxiety. e) Levlt of anxiety of believer in patient's family is lower than unbeliever. f) The academical background of patient's family is in inverse proportion to the level of anxiety g) Level of state anxiety of patient's family at the time of admission is positively related to the level of trait anxiety.
