The clinical cases presented here involve skeletal Class III malocclusion cases treated with maxillary protraction in a relaticely short period of time with good results. When used on young patients, satisfactory results were obtained in a short period of time, but even for those with less growth potential remainig, skeletal enhancement was still evident. However, data on the criteria of diagnosis or relapse following maxillary protraction is limited despite the number of studies on the subiect. The present study could not incude the observations on retention and relapse, and further studies in the future may include such observations.

Although vascular injuries associated with femoral intertrochanteric fractures have been reported infrequently, bleeding due to vascular injury can lead to severe complications that can be potentially life and limb-threatening. The authors report a case of an injury of the ascending branch of the lateral femoral convolutional artery in a patient who underwent surgical treatment for a femoral intertrochanteric fracture. Vascular injury occurred due to the sharp margin of displaced lesser trochanter five weeks after surgery. Percutaneous transcatheter embolization was done and improved without additional complications. Therefore, the surgeons need to be aware of possible associated vascular injuries caused by displaced lesser trochanter fragments in femoral intertrochanteric fractures.

Purpose: This study aimed to identify the factors influencing COVID-19 vaccination intentions in nurses. Methods: The participants were 184 nurses in Korea. Data were collected using a Google Form online survey method in February, 2021, and analyzed using an independent t-test, one-way ANOVA, Pearson correlation, and multiple regression analysis with the SPSS/WIN 26.0 program. Results: COVID-19 vaccination intention in nurses was correlated significantly with vaccine hesitancy (r = .58, p < .001), risk perception of COVID-19 (r = .22, p = .003), perception of vaccination as a professional duty (r = .59, p < .001), and attitude towards workplace infection control policies (r = .20, p = .007). Vaccine hesitancy (β = .40, p < .001) and the perception of vaccination as a professional duty (β = .44, p < .001) significantly influenced COVID-19 vaccination intention. The model developed in this study explained 50% of the variation in COVID-19 vaccination intention. Conclusion Improving the perception of vaccination as a professional duty and lowering vaccine hesitancy may enhance nurses’ COVID-19 vaccination intention. Above all, it is necessary to provide programs to encourage voluntary recognition of vaccination as a professional duty and develop strategies to reduce hesitancy toward COVID-19 vaccinations.

A short femoral stem (type 1 cementless stem) is being increasingly used to perform total hip arthroplasty; however, various types of intra- or postoperative periprosthetic fractures have been reported in recent times. A 66-year-old woman with a history of bilateral total hip arthroplasties using a type 1B femoral stem was admitted 2 months post-operation for a Vancouver type C periprosthetic fracture. She underwent open reduction and internal fixation; however, we observed recurrent non-union and plate breakage at the same site. In this case report, we discuss the factors associated with treatment failure in patients with a Vancouver type C periprosthetic fracture following type 1 femoral stem im-plantation.

BACKGROUND: Procedures in medical papers should be described in sufficient detail to allow other researchers to reproduce the results. The apparatus including anesthesia machine should be given, too. Anesthesia machine has dramatically improved as bioengineering has developed. There are several ventilator settings in modern anesthesia machines. However, it seems that only a few ventilator settings are described even though modern ventilators are used in research. The purpose of this study is to investigate that how many ventilator parameters were described in the papers of the Korean Journal of Anesthesiology from 2001 to 2006. METHODS: All of papers with human general anesthesia were reviewed except case reports, and papers regarding only induction or intubation procedures. Recruited articles were grouped into papers with strongly related to respiratory parameters (STP), and into ones with slightly related to them based on the research topics. The description of following categories was counted in each paper; the type of anesthesia machine, tidal volume, respiratory rate, inspiratory:expiratory ratio, mode of ventilation, pressure set in pressure targeted ventilation, positive end expiratory pressure, inspiratory pause, and inspiratory rising rate. RESULTS: The description rate of each parameters in STP were 36% in the type of anesthesia machine, 66% in tidal volume, 54% in respiratory rate, and 24% in inspiratory:expiratory ratio. The other settings were seldomly mentioned. CONCLUSIONS: Description on the ventilator parameters was sometimes missed. We should describe adequate ventilator settings to reproduce the results because the modern anesthesia machine has additional ventilator options.

PURPOSE: The aim of this study was to identify the factors related to the social distance toward older adults in nursing college students.METHODS: The participants comprised 137 students in a nursing college. Data were collected using self-report questionnaires in March 2019. The measurement instruments included social distance scales, the Fact on Aging Quiz (FAQ I), a 20-item semantic differential scale (to assess attitudes), and the perceived elderly stigma scale. The data were analyzed using descriptive statistics, independent t-tests, one-way analysis of variance (ANOVA), Pearson's correlation coefficient, and a multiple regression analysis.RESULTS: The total score for social distance toward older adults was 3.98±0.54 out of a maximum of 5. Social distance had a statistically significant relationship with knowledge (r=.20, p=.022), attitudes toward older adults (r=−.31, p < .001), and elderly stigma (r=−.27 p=.008). The factors affecting social distance were education in geriatrics (β=.33, p=.004), grade (β=-.29, p=.014), attitudes (β=−.21, p=.018), academic major satisfaction (β=.19, p=.028), and knowledge (β=.15, p=.048); the explanatory power of the model was 34%.CONCLUSION: There is a need for departmental efforts that nursing students acquire correct knowledge about the life and health of the elderly with the aging process and develop positive attitudes toward older adults through various experiences in gerontological nursing practicum and community senior-college student link programs.

PURPOSE: This article is a comprehensive review for concept clarification of critical thinking, clinical reasoning, and clinical judgment, which still lack a consensus and are of mixed use. METHODS: Norris's method of concept clarification was used to review concepts that have no clear definition or conceptualization yet. RESULTS: This review summarized literature from various disciplines, classified each concept based on similarities and differences, and provided hypothetic conceptual schema. CONCLUSION: Clinical reasoning and clinical judgment are clinical situation specific concepts, while critical thinking is a concept applied in general situations. Critical thinking is a broader concept and serves as a foundation for clinical reasoning and clinical judgment. Clinical reasoning precedes clinical judgment. Clinical judgement implies the end point or conclusion of clinical reasoning. Each of critical thinking, clinical reasoning, and clinical judgment is a cognitive and affective process not a psychomotor process. The concept of clinical competency involves action taken after the cognitive processes of clinical reasoning and clinical judgment.

An 84-year-old female visited with an intertrochanteric femoral fracture. The patient had undergone an open reduction and internal fixation with a compressive plate and elastic nail in an ipsilateral atypical diaphyseal femoral fracture in the past. Compressive plate and elastic nail remained, and anterolateral bowing was presented. To treat the periprosthetic trochanteric fracture, a proximal femoral nail was used without removing the previously inserted compressive plate. Under the “rendezvous” technique, using a combination of fixating intramedullary nail and compressive plate simultaneously, the distal screw was fixed, and a femoral head lag screw was inserted after reducing the fracture. Complete union of the fracture was achieved 16 months after the operation, and a decrease in mobility function was not found postoperatively. The authors report this case for the “rendezvous” technique as a treatment option for elderly patients with periprosthetic trochanteric fractures, who had previously undergone surgical treatment for ipsilateral atypical diaphyseal femoral fractures with anterolateral bowing.

PURPOSE: The purpose of this study was to compare the clinical and radiological outcomes of locking compression plate (LCP)-screw fixation and tension band wiring (TBW) fixation in isolated lateral malleolar fractures.MATERIALS AND METHODS: From May 2016 to August 2018, 52 patients with isolated lateral malleolar fracture were retrospectively reviewed. They were divided into 30 cases of the LCP fixation group (Group I) and 22 cases of the TBW fixation group (Group II). The clinical and radiological results of those groups were compared. Pearson chi-square tests and independent t-tests were used in the statistical analysis.RESULTS: The mean length of the surgical incision was 8.3 cm in Group I and 4.9 cm in Group II. Radiological union was obtained at a mean of 8.4 weeks in both groups. The mean American Orthopaedic Foot and Ankle Society score was 90 (range, 85–97) and 92 (range, 85–100) in Groups I and II, respectively, at the last follow up.CONCLUSION: Both the LCP-screw and TBW techniques revealed excellent results in isolated lateral malleolar fractures. The tension band technique may be a fine alternative method of fixation in the treatment of isolated lateral malleolar fracture.
