BACKGROUND: Cubitus varus and cubitus valgus deformities are common complications of distal humeral fractures in children. We evaluated the usefulness of supracondylar dome osteotomy as a treatment option for adults with cubitus varus or valgus deformity developed during childhood. METHODS: Ten patients who had received supracondylar dome osteotomy and stabilization with plates to treat cubitus varus or valgus deformity between July 2006 and August 2013 were included in this study. Their mean age at the time of surgery was 36.50 ± 10.22 years. The mean follow-up duration was 54.80 ± 32.50 months. We evaluated humerus-elbow-wrist angles (HEWA), improvements in the lateral prominence index (LPI) or medial prominence index (MPI), Mayo elbow performance scores (MEPS), and overall results in accordance with the Banerjee criteria. RESULTS: For the six patients with cubitus varus, the mean postoperative HEWA, mean correction angle, and mean improvement in LPI were 9.72°± 3.95°, 27.67°± 10.75°, and 6.92% ± 3.40%, respectively. For the four patients with cubitus valgus, the mean postoperative HEWA, mean correction angle, and mean improvement in MPI were 14.73°± 2.97°, 11.55°± 3.26°, and 11.33% ± 6.39%, respectively. There was no significant difference between postoperative and preoperative mean MEPS. The subjective ulnar nerve symptoms were alleviated in all patients. The overall results were excellent in six and good in four patients. CONCLUSIONS: This study suggests that supracondylar dome osteotomy with secure fixation using double plates may be useful in correcting cubitus varus or cubitus valgus deformity, yielding good functional outcomes in adults.

This project developed a neural network based on nursing diagnoses among 98 nursing diagnoses Korea Nurses Association recommended when related factors and clinical signs are entered. This nursing diagnosis system consists of five sub-systems: data-input system from which a nurse can obtain knowledge from experts; data-base system in which nurses can manage statistical data; inference support system which provides learning effect; inference system which increases inference ability of nurses using existing data and nursing diagnoses data; and result-retrieve system in which nurses can look at the outcomes of nursing process. This nursing diagnosis system provides a interface which enables maintenance and revision easier as well as to induce a diagnosis through the communication between the nurse and the patient. In addition, this system makes nurses determine the nursing diagnoses in a more accurate manner by linking the learning effect of the system whit intra-neural network algorithm. This nursing diagnosis system will assist nurses to provide foster and more accurate way to implement nursing diagnosis.

BACKGROUND: Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae are main pathogens of bloodstream infection. We compared the epidemiology of ESBL-producing E. coli and K. pneumoniae. METHODS: From January 2003 through March 2007, we retrospectively investigated the clinical characteristics and comorbidities of patients with bloodstream infection by ESBL-producing E. coli and K. pneumoniae. RESULTS: During the study period, 79 patients (54 with E. coli and 25 with K. pneumoniae) with blood cultures positive for ESBL-producing E. coli or K. pneumoniae were studied. When comparing the source of bloodstream infections, urinary tract infections (UTIs) were more commonly caused by E. coli (24% vs. 0; P=0.007), and respiratory tract and soft tissue infection (36% vs. 15%; P=0.04, 12% vs. 0; P=0.03, respectively) were more commonly associated with K. pneumoniae. Among hospital-acquired bloodstream infection, third-generation cephalosporin was more commonly used in patients with E. coli than patients with K. pneumoniae (81% vs. 24%, P<0.001). Medical devices (central venous catheter and urinary catheter) were more commonly used in patients with K. pneumoniae. CONCLUSION: ESBL-producing E. coli bloodstream infection is more common in urinary tract infections. ESBL-producing K. pneumoniae is more common in respiratory tract infections and in skin and soft tissue infections. In hospital-acquired infections, ESBL-producing E. coli bloodstream infection is more common in biliary tract infection. ESBL-producing E. coli was more commonly associated with prior frequent antibiotics use and K. pneumoniae was more commonly associated with use of medical devices.

PURPOSE: This study was to examine the relationships between knowledge with same sub-areas of education needs and adherence to self-management guidelines, and to investigate the factors that influence adherence. METHOD: One hundred eleven patients with terminal stage of kidney failure were conveniently selected from a university hospital in Incheon. RESULTS: The level of knowledge was high, with a mean score of 15.25. The level of adherence to self-management guidelines was low, with a mean score of 64.53. The patients' education needs were high. The significant influencing factors on adherence were gender, educational level, and two sub-areas of knowledge, 'exercise and daily life' and 'follow-up care and treatment'. CONCLUSION: Relationships between knowledge, education needs, and adherence should be further examined before developing and implementing intervention programs for adherence to treatment guideline in hemodialysis patients.

Purpose: This study aimed to compare the lasting effects of the flossing band technique, dynamic and static stretching on hamstring on range of motion (ROM), muscle activity, and proprioception to identify the most effective pre-exercise method for preventing injuries. Methods: Thirty participants were randomly assigned to the flossing band (FB), dynamic stretching (DS), and static stretching (SS) groups, with 10 subjects in each. Measurements included muscle activity of the biceps femoris vis surface electromyography, knee ROM and proprioception during active knee extension and flexion using a smart joint goniometer. Assessments were conducted before, immediately after, 15, and 30 minutes after each intervention. Results: Proprioception showed no significant differences among groups at any time point. Significant differences in knee ROM were observed in the FB group (except between 15 and 30 minutes after), DS group (except between immediately after and 15 minutes after, and between 15 and 30 minutes after), and SS group (except between before and 15 minutes after, and between before and 30 minutes after). Muscle activity in the FB (except between before and 30 minutes after, and between 15 and 30 minutes after) and SS (between before and immediately after, between immediately after and 30 minutes after, and between 15 and 30 minutes after) groups showed significant differences, while the DS group exhibited no significant changes. Conclusion Although direct comparisons did not establish superiority, within-group analyses indicated that the flossing band technique exhibited longer-lasting effects than dynamic and static stretching, providing valuable insights for injury prevention program design.

OBJECTIVE: Rising from a sitting position is a very common, yet essential activity in daily life. The activity to perform the sit-to-stand (STS) transfer is a prerequisite for upright mobility. This study aims to provide fundamental data concerning the execution of the STS, and in particularly the followings: 1) how do the angles of the lower limbs change throughout the process of rising from a chair; 2) how much motion torque and power in each joint are required per kilogram of body weight to complete the STS transfer? METHOD: Twenty-one children who have developed normally and could understand the command requested are involved as subjects. Their age ranged from 3 to 5 years old. Motion analysis of STS transfer were assessed with the Vicon 370 M.A (Oxford Metrics Limited, United Kingdom). The changes in joint angle, maximal moment and power in lower limb were calculated throughout the STS transfer. RESULTS: A series of transition points was observed in the angles of the hip, knee and ankle joints throughout the sit-to-stand movements, which was classified into five stages. The first stage is trunk and hip flexion phase; second stage, buttock take-off; third stage, ankle dorsiflexion and knee extension; forth stage, just-standing; fifth stage, stabilizing phase. The extension moment of each joint is 0.65 Nm/kg on right, 0.71 Nm/kg on left in hip, 0.41 Nm/kg on right, 0.38 Nm/kg on left in knee and 0.21 Nm/kg on right, 0.22 Nm/kg on left in ankle joint. The extension power is 0.60 watt/kg on right, 0.68 watt/kg on left in hip, 0.59 watt/kg on right, 0.50 watt/kg on left in knee and 0.15 watt/kg on right, 0.15 watt/kg on left in ankle joint. CONCLUSION: A consistent pattern was observed throughout the sit-to-stand transfer and six transition points were observed in the angles of the hip, knee and ankle joints throughout the STS transfer. By these 6 points, the movement of the STS transfer was classified into 5 stages. Major changes in angle, moment, and power of each joint were observed in sagittal plane. There were no side to side difference during the STS transfer.

BACKGROUND: Surgical site infection (SSI) is generally considered second or third most important infection type in nosocomial infections. However, there are only a few national surveillances about surgical site infection and prophylactic antibiotics use. We performed the surveillance of surgical site infections and antibiotic use in joint replacement operation, which is difficult and costly to treat. METHODS: The surveillance study of the hip joint (HRA) and knee joint replacement surgery (KRA) was performed in four university hospitals from July 2006 to December 2006. The Clinical variables, operative risk factors for SSI, and information of prophylactic antibiotics uses were evaluated. SSI surveillance was done in 2 weeks, 1 month, 3 month, 6 month, and 1 year after surgery. RESULTS: A total of 436 cases (HRA, 227; KRA, 209) were enrolled for SSI surveillance. The SSI rates of HRA and KRA were 1.32 (3/227), and 1.44 (3/209) per 100 operations, respectively. The most of operation site was clean wound (97.9%). Staphylococcus aureus was observed in 19.8% before operation and among S. aureus infections about 20% was methicillin-resistant strain. The 1st generation cephalosporins were most frequently used for prophyaxis occupying 65.1%. The median duration of antibiotic use was 12 days (1-79 days). Any other specific risk factors were not correlated with SSI development. CONCLUSION: The multicenter surveillance study of SSI was first performed in Korea. The SSI rate was comparable with SSI reported in other country. We need to analyze the risk factors of SSI after collecting the data through further studies.

Background: The importance of infection with COVID-19 is being emphasized in dentistry with high risks such as aerosols. The purpose of this study is to investigate the knowledge and practice of infection control, stress and coping, and turnover of dental hygienists. Methods: Questionnaire was conducted knowledge and practice of infection control, occupational stress and coping, turnover. Survey data was investigated about 149 dental hygienists from February to March 2021 Data were analyzed t-test, ANOVA, Pearson’s correlation using statistical programs of PASW Statistics ver. 21.0. Results: Regarding occupational stress, relationship conflict was higher in the group with less than 2 years of experience (p＜0.05). Job anxiety, organizational system, inadequate compensation, and workplace culture were highly surveyed in the 3 to 5 year of experience. The group with more than 6 years of experience had the highest perception of lack of job autonomy (p＜0.05). The group with higher knowledge of infection control had lower mean inappropriate rewards and stress (p＜0.05). The group with high infection control performance had a lower average in items such as job instability, organizational system, inadequate compensation, workplace culture, and stress. And problem-focused coping ability was found to be high (p＜0.05). Infection control knowledge and performance were positively correlated (r=0.251, p＜0.01), infection control practice and stress were negatively correlated (r=−0.264, p＜0.01), and stress and emotional coping were positively correlated (r=0.367, p＜0.01). Stress was positively correlated with turnover rate (r=0.549, p＜0.01). Conclusion Infection control training was required to reduce occupational stress. Occupational stress was highly correlated with turnover, a holistic and systemic organizational operation and improvement of the quality of medical care were required to reduce stress.

The cardiovascular system may be one of the target organs of both immunoglobulin G4 related and non-related systemic multifocal fibrosclerosis. We present a case of IgG4 non-related systemic multifocal fibrosclerosis mimicking mitral stenosis on echocardiography. For a more detailed differential diagnosis, we used multimodal imaging techniques. After surgical biopsy around the abdominal aortic area in the retroperitoneum, histological examination revealed IgG4 non-related systemic multifocal fibrosclerosis. We describe the multimodal imaging used to diagnose IgG4 non-related systemic multifocal fibrosclerosis and a positive response to steroid treatment. There have been no previous case reports of IgG4 non-related systemic multifocal fibrosclerosis with intracardiac involvement. Here, we report a case of IgG4 non-related systemic multifocal fibrosclerosis mimicking mitral stenosis.
