Distal phalanx fractures are the most common injuries of the hand, and K-wire fixation is commonly performed for unstable fractures. However, there is no consensus regarding the number of K-wires to use in bone fixation. We aimed to compare the results between single and dual K-wire pinning. This retrospective study enrolled patients who underwent K-wire pinning for unstable distal phalanx fractures, including the shaft and tuft, from June 2016 through April 2020. We divided patients into two groups based on the number of K-wires used for bone fixation (single vs. dual). Clinical and radiographic data were measured and compared between the two groups. Additionally, multivariable logistic analysis was performed to identify the risk factors for nonunion. A total of 80 patients were enrolled. Among them, 27 were managed with a single K-wire and 53 with a dual K-wire. There was no significant difference in the union rate between the single and dual K-wire groups (77.7% vs. 84.9%, respectively), but time to union was significantly longer in the single K-wire group (11.3 vs. 8.4 weeks; p =.003). The presence of a bone gap after fixation was a risk factor for nonunion. Our study showed that the union rate was comparable between single and dual K-wire pinning in distal phalanx fractures. However, dual K-wire pinning shortened the union time. [ABSTRACT FROM AUTHOR]

Aim: We examined Korean nurses professional quality of life, emotional labour and workplace violence to guide development of interventions to improve nurses professional quality of life. Background: Nurses face heavy exposure to emotional labour and workplace violence. Stress experienced by nurses reduces compassion satisfaction and increases compassion fatigue. Methods: Participants comprised 399 clinical nurses chosen by convenience sampling. Questionnaires measured demographic characteristics, emotional labour, workplace violence and professional quality of life. Results: Nurses professional quality of life was affected by emotional labour and workplace violence. Graduate educational level, emotional exposure and emotional supervision were associated with compassion satisfaction. Burnout was commonly associated with emotional exposure, experience and supervision of workplace violence. Secondary traumatic stress was associated with emotional exposure and experience of workplace violence. Conclusions: We elucidated the relationship between professional quality of life, emotional labour and workplace violence. Raising professional quality of life among nurses requires regular analysis of emotional labour and provision of organizational‐level interventions. Counselling programmes that address violence prevention education and comprehensive response strategies among nurses and policies that foster an organizational culture of respect and cooperation in hospitals are needed. SUMMARY STATEMENT: What is already known about this topic? Promoting nurses professional quality of life is important in managing the quality of nursing care.Nurses with exposure to emotional labour show negative health effects, reduced willingness and ability to work, frequent absences, dissatisfaction and turnoverWorkplace violence negatively affects professional quality of life among clinical nurses. What is already known about this topic? Compassion satisfaction was highly related to organizational management systems for emotional labour and workplace violence.Burnout was associated with the magnitude of exposure to emotional labour and experience of workplace violence and negative organizational management systems for workplace violence.Secondary traumatic stress was associated with the magnitude of exposure to emotional labour and experience of workplace violence. The implications of this paper: To increase nurses professional quality of life, organizational management systems that address and reduce emotional labour and workplace violence are critical.It is necessary to develop programmes that address violence prevention education and comprehensive response strategies regarding emotional labour.Counselling programmes that address violence prevention education and comprehensive response strategies among nurses and policies that foster an organizational culture of respect and cooperation in hospitals are needed.

OBJECTIVE. The purposes of this study were to identify the similarities and differences among the Korean Thyroid Imaging Reporting and Data System (TIRADS), American College of Radiology (ACR) TI-RADS, and European TIRADS and to compare the diagnostic performance of sonographic fine-needle aspiration (FNA) criteria for detecting malignant thyroid nodules. MATERIALS AND METHODS. This study included 2274 consecutively evaluated thyroid nodules 1 cm or larger in 1836 patients with final diagnoses from January 2011 to December 2016. US features of the nodules were retrospectively reviewed and classified according to three published guidelines from international societies. We compared the US lexicons, categories, and diagnostic performance of the FNA criteria for malignant nodules among the three reporting systems. RESULTS. Of the 2274 thyroid nodules, 1974 (86.8%) were benign and 300 (13.2%) were malignant; 93.7% of all malignancies were papillary carcinoma. Most of the US lexicons were similar among the three systems except for the definition of echogenicity of a nodule of mixed echogenicity in European TIRADS. Although the categories had strong correlations ( r = 0.777-0.877, all p < 0.001) among the three systems, significant differences were observed in categories 5, 4, and 3 of nodules (all p < 0.001) and in the sensitivity, specificity, and rate of unnecessary FNA of the FNA criteria for malignancy (all p < 0.001). CONCLUSION. Although the three systems had similarities in most US lexicons, significant differences were observed in the classified categories and diagnostic performance of the FNA criteria for malignancy.
