For the study of its stability when the screw has been fixed after sagittal split ramus osteotomy(SSRO) of the mandible, the methods of screw arrangement are classified into two types, triangular and straight. The angles of screws to the bone surface are classified as perpendicular arrangements, the 60degrees anterioinferior screw, known as triangular, and the most posterior screw, called straight arrangement, thus there are four types. The finite element method model has been made by using a three dimensional calculator and a supercomputer. The load directions are to the anterior teeth, premolar region, and molar region, and the bite force is 1 Kgf to each region. The distribution of stress, the von-Mises yield strength, and safety of margin refer to the total sum of transformed energy have been studied by comparison with each other. The following conclusion has been researched : 1. When shear stress is compared, in the triangular arrangement in the form of "giyeok", the anterosuperior screw is seen at contributing to the support of the bone fragment. In the straight arrangement, substantial stress is seen to be concentrated on the most posterior angled screw. 2. When the von-Mises yield strength is compared, it seemed that the stress concentration on the angled anteroinferior screw is higher, it shows a higher possibility of fracture than any other screw. In the straight arrangement, stress appeared to be concentrated on the most posteriorly angled screw. 3. When the safety margins of the transfomed energy are compared, the energy conduction is much greater in the case of the angled screw than in the case of the perpendicular screw. The triangular arrangement in the form of "giyeok" shows a superior clinical sign to that of the straight arrangement. Judging from the above results, when the screw fixation is made after SSRO in practical clinical cases, two screws should be inserted in the superior border of mandibular ramus and a third screw of mandibular inferior border should be inserted in the form of triangular. All screws on the bony surface should be placed perpendicularly-90 degrees angles apparently best promote bony support and stability.

PURPOSE: It is expected that there will be a difference in job stress between special unit (operating room, anesthesia room) nurses and general ward nurses in general hospitals, but factors influencing job stress have not been examined. This study reports on research to examine the sources of verbal abuse in the workplace. METHODS: Participants were 243 nurses (special unit 112, general ward 132) working in a hospital in I city. Data collection period was March 18 to March 25, 2016 and questionnaires were used to collect data. Comparison of differences in influence of verbal abuse on job stress between special unit and general ward nurses was analyzed with multiple hierarchical regression. RESULTS: In special unit nurses, verbal abuse from doctors and/or nurses influenced their job stress (Adj. R²=.545). In general ward nurses, verbal abuse from patients and/or care-givers influenced their job stress (Adj. R²=.241). CONCLUSION: Findings indicate a need to campaign for increase respect among nurse-doctor, nurse-nurse, and nurse-patients/care givers because verbal abuse from doctors, nurses, and patients/care-givers causes negative attitudes in nurses. General ward nurses in particular should provide sufficient explanation to patients about nursing services because verbal abuse from patients/care-givers is related to their complaints about nursing care.

Cohen–Gibson syndrome (CGS) was first reported by Cohen et al., who identified the mutation of the gene encoding the embryonic ectoderm development (EED) in a patient with phenotypes similar to Weaver syndrome. CGS manifests as an overgrowth and intellectual disability, in addition to the characteristic facial features and organ anomalies. CGS has been reported in only 11 unrelated patients since 2015. A girl aged 6 years and 3 months presented with seizures. She had macrosomia, a dysmorphic face, and intellectual disability. Her mother and younger sister and brother also had macrosomia, intellectual disability, and similar facial features; additionally, her mother experienced seizures and had an arachnoid cyst, while her siblings had valvar pulmonary stenosis. Whole-exome sequencing for the proband revealed a mutation of EED (c.581A>G, p.Asn194Ser), which was also verified in the mother and both siblings using Sanger sequencing. This is the first report of familial CGS.

BACKGROUND AND OBJECTIVES: We checked traditional and high-level precordial electrocardiogram (ECG) leads in patients who had undergone right ventricular outlet obstruction (RVOT) reconstruction surgery and evaluated the effect of ECG lead position on their QRS duration. SUBJECTS AND METHODS: We enrolled 34 patients who had undergone surgery for congenital heart disease with RVOT obstruction and who had received followed up care that included recorded ECG at a pediatric cardiac out-patient clinic. The control group included 29 patients who did not have hemodynamically significant intracardiac abnormality. We recorded traditional standard 12-leads ECG from the 4th intercostals space, and moved the precordial leads to the 3rd and 2nd intercostals spaces, and recorded ECGs repeatedly. RESULTS: In all groups, there was no significant difference of mean QRS duration and QTc interval between traditional standard 12-leads ECGs and ECGs at higher intercostals spaces. There was no significant difference of ECG parameters between groups. In the control group, the degree of the change between the 4th intercostals space (ICS) QRS and 3rd ICS QRS was significant (p=0.031), and although, it was insignificant, ECGs at the 3rd ICS showed decreased QRS duration in group 1 (V1: 3rd ICS 119.21+/-21.53 msec vs. 4th ICS 122.80+/-31.78 msec. V2: 3rd ICS 113.68+/-19.43 msec vs. 4th ICS 118.24+/-19.16 msec). CONCLUSION: Although the positional change of ECG leads did not result in a significant effect on measuring QRS duration after surgery, ECG leads at the 3rd ICS rather than at the 4th ICS may cause alteration of ECG readings. Therefore, we suggest that ECGs should be recorded in as accurate a position as possible.

PURPOSE: The purpose of this study was to examine the effect of a group coaching program (GCP) on depression, anxiety, and hope in women breast cancer patients undergoing chemotherapy. METHODS: A total of 152 patients were enrolled and randomly assigned to an experimental group receiving the GCP (N=76) and an untreated control group (N=76). Data collection consisted of three measurements of depression, anxiety, and hope (pre, post, and 3weeks later). The intervention was a one-time GCP consisting of 5 subparts for 30~40 minutes for a group of 3~4 people, conducted by a single nurse. RESULTS: The scores of depression, anxiety, and hope changed significantly over time (p<.001, p<.001, p<.001). Depression, anxiety, and hope changes were significantly different between the experimental and control groups (p<.001, p<.001, p<.001). There was a difference in depression, anxiety, and hope among the groups according to the implementation of the GCP (p<.001, p<.001, p<.001). In the experimental group, depression, anxiety, and hope level were significantly different between the pre- and post-test (p<.001), pre- and 3weeks later-test (p<.001), but not in the control group. CONCLUSION: The GCP for women breast cancer patients receiving chemotherapy was effective in reducing depression and anxiety, and increasing hope.

Laparoscopic cholecystectomy is a relatively new non-invasive surgical procedures, enjoying ever-increasing popularity and presenting new anesthetic challenges. The advantages of shorter hospital stay and more rapid return to normal activities are combined with less pain associated with the small limited incision and less postoperative ileus. During this procedure, the deliberate pneumoperitoneum with carbon dioxide(CO2) insufflation may cause some problems such as hypercarbia, hypertension, pneumomediastinum and other cardiovascular impairments. This study was performed to search a anesthetic method, which has least increase in blood pressure during CO2 insufflation, and to find out whether increased PaCO2 is a major causative factor in the changes of blood pressure during this period. Sixty patients of ASA class 1 or 2 were classified randomly into 3 groups. Group C(control group) was received enflurane-N2O-O2, and others were recieved enflurane-propofol(group P), or enflurane-propofol-fentanyl(group F), respectively. The blood pressure and heart rate were measured at 1 min before CO2 insufflation and 1 min, 5 min, 15 min after insufflation and 1 min before deflation, 5 min after deflation. Also PaCO2 were checked at 1 min before, and 15 min after insufflation. The results were follows ; 1) Changes of arterial pressure : The control group showed most prominent increasing in systolic and mean blood pressure during CO2 insufflation(P<0.05). Group F produced the least increase in blood pressure during CO2 insufflation, compared with group C and P(P<0.05). 2) Changes of heart rate : Although, in the preinsufflation period, heart rates in the group F were significantly lower than other groups, there were no significant changes in heart rates in each group. 3) Changes of PaCO2: There were no siginificant increases in PaCO2 in each group, and no differences between the groups. In conclusion, fentanyl and propofol added light enflurane anesthesia could be a method of the least increase in blood pressure during the laparoscopic cholecystectomy, and increased PaCO2 would not be a major causative factor in hypertension during CO2 insuftlation.

Plastic bronchitis is a rare disorder characterized by the formation of extensive, obstructing endobronchial casts. It is associated with asthma and complex cardiac defects such as those requiring the Fontan procedure. The treatment of plastic bronchitis comprises conventional therapy involving spontaneous expectoration and bronchoscopic removal and specific therapy with several new drugs. Herein, we describe the cases of 2 patients diagnosed with plastic bronchitis accompanied with a different underlying disease, which were treated with inhaled corticosteroid and low-dose oral clarithromycin.

PURPOSE: We evaluated the characteristics of patients with Kawasaki disease (KD) who presented with only fever and cervical lymphadenopathy on admission, and compared them with the characteristics of those who presented with typical features but no cervical lymphadenopathy. METHODS: We enrolled 98 patients diagnosed with KD. Thirteen patients had only fever and cervical lymphadenopathy on the day of admission (group 1), 31 had typical features with cervical lymphadenopathy (group 2), and 54 had typical features without cervical lymphadenopathy (group 3). RESULTS: The mean age (4.3+/-2.1 years) and duration of fever (7.5+/-3.6 days) before the first intravenous immunoglobulin (IVIG) administration were highest in group 1 (P=0.001). Moreover, this group showed higher white blood cell and neutrophil counts, and lower lymphocyte counts after the first IVIG administration as compared to the other groups (P=0.001, P=0.001, and P=0.003, respectively). Group 1 also had a longer duration of hospitalization and higher frequency of second-line treatment as compared to groups 2 and 3 (group 1 vs. group 2, P=0.000 and P=0.024; group 1 vs. group 3, P=0.000 and P=0.007). A coronary artery z score of >2.5 was frequently observed in group 1 than in group 3 (P=0.008). CONCLUSION: KD should be suspected in children who are unresponsive to antibiotics and have prolonged fever and cervical lymphadenopathy, which indicates that KD is associated with the likelihood of requiring second-line treatment and risk of developing coronary artery dilatation.

Social support was found to have buffering effects on the stress response of stroke patients. Especially, the aspects of social support found to be most influential were support from a close, personal source, and overall satisfaction with support. The purpose of this study was to identify the current social network and its characteristics according to gender difference in post-hospitalized stroke patients in Korea. The sample consisted of a convenience sample of 254 patients was recruited 129 men and 125 women who were receiving follow-up care at outpatients clinics. Four aspects of social support-source, quantity, quality & type-were measured using the modified Social Support Inventory for Stroke Survivors(SSISS) which was developed by McColl & Friedland(1989). Regarding sources of social support, 61.4% reported for 'spouse' as primary caregiver and 31.9%, 'children'. But the distribution of sources of personal support were related to gender; 82.2% of male patients had support from their spouses, while only 40% of female patients reported from 'spouse' but 51.4% from 'children'. Among the children, daughters and sons were more significant support persons than daughters-in-law. The percentages for sources of these significant other support persons were 55.5% for 'children', 8.7% for 'spouse', and 8.3% for 'brothers'. The physician at the outpatient department was the main source of professional support. For the quantity and quality of social support, the primary caregiver's support was more significant than support by significant other persons. Male patients reported that primary the caregiver' support was greater than that of significant other persons, while female patients perceived significant other persons as giving greater support. Regarding the type of perceived social support, the stroke patients were highly satisfied with the primary caregiver's support in aspects of instrumental, emotional, and informational support. They also reported high satisfaction with support from significant others' support in the aspect of emotional support, while emotional and informational support from professionals was reported as satisfactory. In conclusion, gender difference in the social support network was found in that male patients perceived more support from their spouses, while female patients perceived more support from their children as compared to their spouses.
