Although intramedullary nailing is mostly used in the management of fractures in the long bone shaft, plate fixation is still alternative option in periprosthetic or metaphyseal fractures. For the rigid fixation during plating, sometimes we need wiring. Many surgeons experience slippage of wire resulting in loss of rigid fixation because plate and wire is so slippery and the diameter of bone is changing by level especially in the metaphyseal area. Wiring plate(CHO plate) was designed to prevent slippage. This plate has transverse holes for wires between screw holes on traditionally used dynamic compression plate. Sixteen fractures of long bone shaft were fixed with wiring plate and 11 cases which were followed up for more than one year were evaluated. There were periprosthetic fractures(4 cases), spiral or butterfly fractures(4 cases) and fractures of poor bone quality(two cases of malignancy and one case of osteoporosis). Nine cases were successfully reduced and the healed without loss of fixation. In two cases, delayed union and nonunion were observed due to wire breakage with plate loosening. Preliminarily, wiring plate fixation can be used for the periprosthetic fracture and one of alternative option in butterfly or spiral fracture and fracture in osteoporotic bone or pathologic fracture.

PURPOSE: To evaluate retrospectively the survival outcome, patterns of failure, and complications in patients treated with postoperative chemoradiotherapy (CRT) in advanced gastric cancer. MATERIALS AND METHODS: Between January 2000 and December 2006, 80 patients with advanced gastric cancer who received postoperative concurrent CRT were included. Pathological staging was IB-II in 9%, IIIA in 38%, IIIB in 33%, and IV in 21%. Radiotherapy consisted of 45 Gy of radiation. Concurrent chemotherapy consisted of a continuous intravenous infusion of 5-fluorouracil and leucovorin on the first 4 days and last 3 days of radiotherapy. RESULTS: The median follow-up period was 48 months (range, 3 to 83 months). The 5-year overall survival, disease-free survival, and locoregional recurrence-free survivals were 62%, 59%, and 80%, respectively. In the multivariate analysis, significant factors for disease-free survival were T stage (hazard ratio [HR], 0.278; p = 0.038), lymph node dissection extent (HR, 0.201; p = 0.002), and maintenance oral chemotherapy (HR, 2.964; p = 0.004). Locoregional recurrence and distant metastasis occurred in 5 (6%) and 18 (23%) patients, respectively. Mixed failure occurred in 10 (16%) patients. Grade 3 leukopenia and thrombocytopenia were observed in 4 (5%) and one (1%) patient, respectively. Grade 3 nausea and vomiting developed in 8 (10%) patients. Intestinal obstruction developed in one (1%). CONCLUSION: The survival outcome of the postoperative CRT in advanced gastric cancer was similar to those reported previously. Our postoperative CRT regimen seems to be a safe and effective method, reducing locoregional failure without severe treatment toxicity in advanced gastric cancer patients.

PURPOSE: We evaluated the clinical and radiological results of arthroscopic ankle fusion using 2 medial screws which had advantages of less morbidity, early weight-bearing and high union rate. MATERIAL AND METHODS: From April, 2002 to March, 2004, 8 patients who had ankle osteoarthritis were treated by ankle fusion using 2 medial screws under arthroscopy; five patients with post-traumatic osteoarthritis, two with post-infectious arthritis and one with paralytic foot. There were 5 male and 3 female. Average age was 67 years old ranging from 57 to 71 years. We evaluated them clinically preoperative and postoperative using AOFAS score, VAS pain scale and patient's satisfaction. In regard to radiological fusion, we checked them by simple AP, lateral and mortise view. Follow up period was average 11 months (range, 6~24 months). RESULTS: All ankles were successfully fused with 2 medial screws under arthroscopy. The mean time of fusion was 10.5 weeks (range, 8~14 weeks). Patient's satisfaction checked at 6 months after operation had favorable results (excellent and good 75%). One case had pain on medial malleolar area because of screw's protrusion. CONCLUSION: Arthroscopic ankle fusion using 2 medial screws was good modality of ankle fusion with less morbidity and early weight-bearing in some cases of ankle arthritis.

PURPOSE: To evaluate the clinical and radiological results of the treatment of mid-shaft clavicular nonunions using intramedullary fixation with threaded Steinmann pin and bone grafting. MATERIAL AND METHODS: In 16 patients treated with intramedullary fixation of threaded Steinmann pin and autogenous iliac bone grafting for the mid-shaft clavicular nonunions, 10 patients with follow-up over 1 year were investigated. All patients (10 clavicle fractures) underwent conservative treatment initially. The average age of patients was 56 years old (range, 18~70 years old). Eight cases were atrophic nonunions, two hypertrophic. A clinical assessment was evaluated postoperatively after 5 months according to the evaluation method of Kona et al. RESULTS: According to the evaluation method of Kona et al, four cases achieved excellent results, five cases good, and one case achieved a fair result. The average period until bony union was 9 weeks (range, 7~12.5 weeks) without infection, pin migration or breakage. One case showed skin irritation by lateral margin of Steinmann pin, which was subsided by pin removal after bony union. CONCLUSION: We obtained satisfactory results and have concluded that intramedullary fixation with threaded Steinmann pin and bone grafting could appropriately treat nonunions of the mid-clavicular fracture occurred after conservative treatment, because it minimizes soft tissue injury, gets relatively stable fixation and early ROM, predicts early bone union, facilitates pin removal under local anesthesia.

Purpose:
The purpose of this study was to explore nurses’ experience with caring for COVID-19 patients in a negative pressure room amid the spread of the pandemic.
Methods:
This study was a qualitative research, and focus group interviews were used to collect data. Three focus groups comprising 19 nurses were interviewed from February 17 to 25, 2021. All interviews were recorded and transcribed verbatim with the consent of the participants. The verbatim transcripts were scrutinized using thematic analysis.
Results:
Two main themes emerged from the analysis: ‘Struggling in an isolated space’ and ’Limitations of nursing infrastructure and system’. The nurses caring for COVID-19 patients experienced anxiety and fear about the infection, physical exhaustion, emotional burnout, and a sense of duty as a nurse. They also acknowledged the lack of guidelines, increased task and burden, limitations of nursing care, and the demand for improving the limitations of the nursing system.
Conclusion
The results of this study demonstrate that nurses caring for COVID-19 patients encounter physical and emotional problems within the limited healthcare system. The study suggests that comprehensive interventions are needed for nurses. Furthermore, detailed guidelines, strengthening of nursing personnel, and improvements to the nursing system are vital to effectively cope with the pandemic. The government and medical institutions should be aware of the needs of nurses and what they are going through, and make efforts to improve the quality of life of healthcare workers and create a safe healthcare environment.

This study sought to describe and to evaluate the characteristics of the Health Screening Records Database (HSRD) of the Korea Association of Health Promotion as a data source for epidemiologic studies. The HSRD was compared to a National Health Insurance Service-Health Screening Cohort (NHIS-HEALS) database for 2015. Common variables between the databases were selected, and sex-based analyses were conducted. The HSRD showed statistical concordance when NHIS-HEALS estimates fell within the HSRD estimate's 95% confidence interval. The HSRD and NHIS-HEALS included 946461 and 111690 participants in health screening programs, respectively. Compared to the NHIS-HEALS, the HSRD had more female (55.2% vs. 42.6%) but fewer older adult participants (34.4% vs. 51.2%). Virtually all variables had clinical concordance, with some having statistical concordance as well, among both general and life-transition program participants. The HSRD comprised more clinical information over a wider age range in contrast to the NHIS-HEALS, while showing clinical concordance. Providing more comprehensive clinical data, the HSRD may serve as an alternative resource for epidemiologic studies.

Solitary fibrous tumor (SFT) is uncommon and known to affect in middle-aged adults, with rare reports of occurrences in children. Although frequently involving the pleura, recent reports show that SFT may also involve extrapleural sites. SFT is known as a benign tumor, but in some cases SFT recurs, invades locally, or shows malignant transformation. We experienced a case of SFT that developed in the axilla of a 4-year-old girl with multiple congenital anomalies with constitutional chromosomal abnormality of 46,XX[44]/47,XX,+mar[11]. Her tumor could not be surgically resected due to the patient's multiple anomalies including congenital heart disease, chronic lung problem and seizure disorder. She died of congestive heart failure with respiratory failure due to tumor growth. This report is meaningful not only because SFT affected a pediatric patient with a constitutional chromosomal abnormality, but also because the tumor originated from the axillary area, a site of origin rarely reported for SFTs.

Isolated myeloid sarcoma is a rare extramedullary manifestation, characterized by the presence of myeloid blasts in the body and occurring without bone marrow involvement. While the isolated myeloid sarcoma involvement in the nasal cavity of adults has been reported sparsely, there have been no documented cases involving children in South Korea. Given its rarity, diagnosing isolated myeloid sarcoma is challenging without resorting to a biopsy accompanied by a comprehensive panel of immunohistochemistry. In this context, we present a case of a 5-yearold child diagnosed with isolated myeloid sarcoma situated within the right nasal cavity. Notably, this case is unique as there is no evidence of bone marrow invasion or underlying hematological disorders.

BACKGROUND AND PURPOSE: To estimate clinical roles of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) versus angiography and ultrasonography in carotid plaque characterization. METHODS: We characterized two groups of patients with recently (<1 month) symptomatic (n=14; age=71.8+/-8.6 years, mean+/-SD) or chronic (n=13, age=68.9+/-9.0 years) carotid stenosis using a battery of imaging tests: diffusion magnetic resonance (MR) imaging, MR or transfemoral angiography, duplex ultrasonography (DUS), and carotid FDG-PET/computed tomography. RESULTS: The degree of angiographic stenosis was greater in patients with recently symptomatic carotid plaques (67.5+/-21.5%) than in patients with chronic carotid plaques (32.4+/-26.8%, p=0.001). Despite the significant difference in the degree of stenosis, lesional maximum standardized uptake values (maxSUVs) on the carotid FDG-PET did not differ between the recently symptomatic (1.56+/-0.53) and chronic (1.56+/-0.34, p=0.65) stenosis groups. However, lesional-to-contralesional maxSUV ratios were higher in the recently symptomatic stenosis group (113+/-17%) than in the chronic stenosis group (98+/-10%, p=0.017). The grayscale median value of the lesional DUS echodensities was lower in the recently symptomatic stenosis group (28.2+/-10.0, n=9) than in the chronic stenosis group (53.9+/-14.0, n=8; p=0.001). Overall, there were no significant correlations between angiographic stenosis, DUS echodensity, and FDG-PET maxSUV. Case/subgroup analyses suggested complementarity between imaging modalities. CONCLUSIONS: There were both correspondences and discrepancies between the carotid FDG-PET images and DUS or angiography data. Further studies are required to determine whether FDG-PET could improve the clinical management of carotid stenosis.
