Amniotic band syndrome is an uncommon congenital fetal abnormality with defects of skin resulting in ringlike strictures about the limbs and occasionally the trunk. Its pathogenesis has been still debated in the literature for many years. Amniotic band syndrome features multiple disfiguring and disabling manifestations. A clinical deformities include limb defects, craniofacial defect, visceral defect, body wall defect and other anomalies. We had experienced a case of amniotic band syndrome with retinopathy of prematurity, bilateral orofacial cleft, aphalangia of right hand, ventricular septal defect and atrial septal defect. We report this case with a brief review of the literature.

PURPOSE: This study was conducted to identify factors that affect nursing performance; Those factors are personal characteristics, sub-categories of empowerment and job satisfaction of clinical nurses. METHODS: Data were collected from November 24, 2012 to March 11, 2013, and participants were 451 hospital nurses in 6 hospitals. Descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficient, and stepwise multiple regression were used for data analysis. RESULTS: Nurses who were older, married, highly educated, in the position of charge nurse, and with longer clinical careers showed relatively higher empowerment, higher job satisfaction, and higher nursing performance than others. Also, there were strong correlations between nursing performance and empowerment (r=.576)/job satisfaction (r=.617). Factors predicted nursing performance were relationship with coworkers (beta=.398), duty (beta=.181), promotion system (beta=.134), and turnover intention (beta=-.109). Factors predicting job satisfaction were competency of empowerment (beta=.249), and clinical career (beta=.151). These 6 factors explained 55.2% of the variance in nursing performance (F=93.37, <.001). CONCLUSION: Regarding human resource management, relationship with co-workers is a changeable factor. Therefore nursing organizations should apply these factors in human resource management to enhance nursing performance and achieve organizational goals.

Three hundred and fourty two patients with a fracture of tibial shaft were treated and managed in the Department of Orthopaedic Surgery, Soon Chun Hyang University Hospital from January 1981 to December 1985. In 147 cases, 62 cases had only tibial shaft fracture and 85 tibial and fibular shaft fracture. All of these were treated conservatively by manipulation and cast immibilization. We analyzed the initial fracture characteristics, the treatment employed, and the subsequent complications in fracture healing in a series of patients who had sustained a tibial shaft fracture with and without a fibular fracture. The results were as follows; 1. Duration of average bone healing was more slowly in the patients more than twenty years old who were treated for a tibial shaft fracture with and without a concomitant fibular fracture than in the patients less than twenty years old. 2. Duration of average bone healing was more slowly by one or two weeks in the the group of tibial shaft fracture without fibular fracture than in than in those with fibular fracture. 3. The frequency of delayed union, nonunion, varus malunion and pain in the ipsilateral ankle joint were more increased in the group of the tibial shaft fractures without fibular fracture in than those with fibular fracture. 4. The frequency of valgus malunion was more increased in the group of the tibial shaft fractures with fibular fracture than in those without fibular fracture.

OBJECTIVES: Significant progress has been made in understanding psychosocial, psychological, and environmental factors associated with suicide. However it is only recently that attention has been paid to the understanding of the neurobiology of suicide. The aim of this study was to examine the relationship between platelet serotonin level and suicidal behavior and psychological features of the suicidal attempters. METHODS: After a suicidal attempt platelet serotonin level was measured from 21 patients and compared it with those from depression patients and normal controls. Also MMPI, HAM-D, Barratt impulsiveness scale(BIS) were done to evaluate their psychological features. RESULTS: 1) There was no significant difference in sex ratio of the suicidal attempters. 2) There was no significant difference in platelet serotonin levels among three groups. 3) The analysis of MMPI revealed that the scores of D, Hs, Pt in clinical scales were significantly higher in suicide patients and scores of D, Pa, Si were in depression patients. 4)The HAM-D score was significantly higher in depression and suicide patients, especially in depression patients. 5) The analysis of Barratt impulsiveness scale revealed that the scores of nonplanning, motor and cognitive impulsiveness scale were significantly higher in suicide patients. CONCLUSIONS: There was no significant difference in platelet serotonin levels among three groups. However the analysis of psychological features revealed significant differences. Therefore we concluded that psychological examinations are benefit to evaluate the suicidal tendency.

Digital technology is gradually expanding its field and has a great influence on various fields of dentistry. Recently in digital dentistry, the importance of superimposing various 3-dimensional (3D) image data is emerging, in order to utilize gathered data effectively for diagnosis and prosthesis fabrication. Integrating data from facial scans, intraoral scans, and mandibular movement recordings can create a virtual patient. A virtual patient is formed by integrating digital 3D diagnostic data such as intraoral and extraoral soft tissues, residual dentition, and dynamic occlusion, and the results of prosthetic treatment can be evaluated virtually. The patients in this case report were a 37-year-old female whose chief complaint is that the appearance of the existing prosthesis was distorted and a 55-year-old female patient whose anterior prosthesis needed to be refabricated after the endodontic treatment. 3D facial scans were obtained from each patient, and the patient’s mandibular movements were recorded using ARCUS Digma 2 (KaVo Dental GmbH, Biberach an der Riss, Germany). The collected data were integrated on computer-aided design (CAD) software (Exocad dental CAD; exocad GmbH, Darmstadt, Germany) and transferred to a virtual articulator to create a digital virtual patient. The temporary fixed prostheses were designed, restored, and evaluated, and it was reflected into the final restorations. With the aid of the virtual dental patient, accuracy and predictability could be increased throughout treatment, simplifying the occlusal adjustment and clinical evaluation with improved esthetic outcomes.

Purpose: This cross-sectional study aimed to identify factors affecting coronavirus disease 2019 (COVID-19) vaccination intention. Methods: For an anonymous online survey, recruitment notices were posted on an anonymous community by each university, and an online survey was conducted through online form from June to July 2021. COVID-19 knowledge and health-protective behavior were measured using a questionnaire based on previous literature and reflecting the Korea Centers for Disease Control and Prevention’s COVID-19 Response Guidelines. The psychological antecedents of vaccination were measured by 5C scale. Results: Two-hundred and ninety-four college students (women 67.3%) answered the survey; 179 (60.9%) reported that they would accept a COVID-19 vaccine. The mean scores for COVID-19 knowledge and health-protective behavior were 22.97 ± 5.33 (out of 35) and 9.92 ± 2.22 (out of 12), respectively. For the psychological antecedents of vaccination, the mean scores for confidence, collective responsibility, calculation, complacency, and constraints were 4.45 ( ± 1.24), 5.61 ( ± 1.09), 5.09 ( ± 1.18), 2.42 ( ± 1.11), and 2.37 ( ± 1.19) out of 5 points, respectively. The confidence, calculation, and collective responsibility were associated with vaccination intention. Additionally, the top reason for those who were less prone to accept vaccination against COVID-19 was concern about vaccine safety. Conclusion The higher the confidence in the vaccine and the higher the collective responsibility, the higher the vaccination intention. As it is a factor related to an individual’s perception of COVID-19 information, it is necessary to increase confidence in the vaccines through obtaining accurate information on the safety, effectiveness, and side effects of the COVID-19 vaccines and vaccination.

BACKGROUND: Although several risk factors associated with reduced age at natural menopause (ANM) have been investigated, the results are inconsistent. Excessive stress, which leads to elevation of stress hormones, can also negatively affect reproductive ability, including by accelerating menopause. However, a direct association between stress level and ANM has not yet been demonstrated. Therefore, the object of this study was to investigate the association between stress level and ANM in Korean women. METHODS: Study participants were Korean women between 40 and 70 years old who were in natural menopause during the 5th Korean National Health and Nutrition Examination Survey (n=3,176). The level of stress in daily life was estimated based on data from the mental health topics of the survey. We used the t-test and one-way analysis of variance to analyze the correlation between stress level and ANM. Regression (beta) coefficients calculated by multiple regression analysis were used to estimate various factors affecting ANM. RESULTS: Women who experienced a high level of stress in daily life had a lower mean ANM than women with a low stress level (50.17+/-3.7 and 50.58+/-3.5 years, respectively), with a statistically significant correlation (P<0.05). This correlation was still observed after adjusting for age, body mass index, menstrual regularity, and personal income (P<0.05 for variables). CONCLUSION: In Korean women between 40 and 70 years of age who are in natural menopause, there is a statistically significant correlation between stress level and ANM. In particular, women who experience a high level of stress in daily life have reduced ANM.

Objective: Severe acute cholecystitis is an infectious disease that requires immediate gallbladder drainage. Although percutaneous transhepatic gallbladder drainage (PTGBD) is the most common method of gallbladder drainage, the optimal timing remains unclear. Methods: This study is a retrospective analysis of patients diagnosed with severe acute cholecystitis who underwent PTGBD between July 2018 to June 2021. This study investigated the effect of time from emergency department arrival to PTGBD (tPTGBD) on patient prognosis. Results: Totally, 48 patients were included in this study. Based on the cutoff value calculated using the Youden index, the group with tPTGBD of <5.93 hours had a shorter hospital stay (10 vs. 13.5 days, P=0.021), lower portion of progression (27:5 [15.6%] vs. 7:9 [56.3%], P=0.004), even they had a higher initial SOFA score (6 vs. 4.6, P=0.049). However, no statistical difference was obtained for the length of ICU stay between both groups (1 vs. 2, P=0.617). Conclusion Executing PTGBD to severe acute cholecystitis patients within 5.93 hours after presenting at the emergency department is associated with reduced progression and hospital stay.

Objective: To evaluate the diagnostic performance of a deep learning algorithm for the automated detection of developmental dysplasia of the hip (DDH) on anteroposterior (AP) radiographs. Materials and Methods: Of 2601 hip AP radiographs, 5076 cropped unilateral hip joint images were used to construct a dataset that was further divided into training (80%), validation (10%), or test sets (10%). Three radiologists were asked to label the hip images as normal or DDH. To investigate the diagnostic performance of the deep learning algorithm, we calculated the receiver operating characteristics (ROC), precision-recall curve (PRC) plots, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) and compared them with the performance of radiologists with different levels of experience. Results: The area under the ROC plot generated by the deep learning algorithm and radiologists was 0.988 and 0.988–0.919, respectively. The area under the PRC plot generated by the deep learning algorithm and radiologists was 0.973 and 0.618– 0.958, respectively. The sensitivity, specificity, PPV, and NPV of the proposed deep learning algorithm were 98.0, 98.1, 84.5, and 99.8%, respectively. There was no significant difference in the diagnosis of DDH by the algorithm and the radiologist with experience in pediatric radiology (p = 0.180). However, the proposed model showed higher sensitivity, specificity, and PPV, compared to the radiologist without experience in pediatric radiology (p < 0.001). Conclusion The proposed deep learning algorithm provided an accurate diagnosis of DDH on hip radiographs, which was comparable to the diagnosis by an experienced radiologist.
