PURPOSE: To evaluate the incidence of disc extrusion and neurologic deficit, the relation between disc extrusion and neurologic deficit and the treatment results according to our basic treatment principles in lower cervical facet joint fracture and dislocations MATERIALS AND METHODS: Twelve patients were evaluated, 8 male and 4 female with an average age of 41 years comprised the group. Six injuries were attributable to automobile accidents, 5 to fall from building, bed, floor and hill, and one to stand on her head. One case was distractive-flexion stage (DFS) 1, 9 cases with DFS 2 and 2 cases with DFS 3. Plain X-ray, CT, Myelo CT and MRI were used as a diagnostic tools. As a treatment criteria, feasibility of closed reduction, status of neuroglogic injury, and stability of injured spine were considered. Anterior cervical discectomy and fusion in accompanied disc extrusion, posterior reduction and fusion with triple wiring in unreduced dislocation, and anterior decompression and fusion in incomplete cord and root injury were selected as a basic treatment principles. RESULTS: Ten out of 12 cases (83%) showed neurologic deficits, 2 complete cord injury, 1 incomplete cord injury, and 7 radiculopathy. Nine out of 12 (75%) demonstrated disc extrusion and all disc extruded patients had neurologic deficits. Anterior cervical discectomy and fusion (ACDF) were performed in 5 cases, ACDF and posterior reduction with triple wiring (PRTW) in 4 cases, PRTW in 1 case, and skull traction and philadelphia brace in 2 cases. Seven radiculpathy patients were completely recovered and one incomplete cord injury patient can ambulate with spastic gait after surgery. There were 2 bed sore and 1 pneumonia in complications. CONCLUSION: Soft disc extrusion should be evaluated carefully with MRI and CT in lower cervical spine injury with the facet joint fracture-dislocations before the decision of treatment. As disc extrusion always accompanies neurologic deficit, it must be surgically treated by anterior cervical discectomy and fusion.

PURPOSE: This descriptive study was to investigate the quality of life in patients with hematopoietic stem cell transplantation (HSCT) from June 1 to October 13, 2007. METHOD: The survey was conducted in 6 different university hospitals which located in Seoul and Jellanamdo province using the Functional Assessment of Cancer Therapy-BMT Scale (FACT-BMT) version 4. We collected a total of 155 questionnaires and analyzed 149 among them. RESULTS: The average score of quality of life was 2.53 out of 5. Physical well being score was highest among sub-domains, followed by emotional well-being, additional concerns, social/family well-being, and functional well-being. Study subjects worried that their conditions would get worse. However study subjects didn't regret having been received HSCT. Age, duration from HSCT, age at diagnosis, income, readmission, HSCT type, educational background, marital status, and the level of activities of daily living were related to quality of life. CONCLUSIONS: The findings of this study indicates that the HSCT survivor's quality of life issue is still important and have to be investigated repeatedly in the future. That is necessary for generalizing QOL outcomes for clinical use. We also suggest to develop interventions to improve QOL.

We performed a retrospective analysis of the results of surgical treatment of sixteen patient with comminuted fracture of the distal femur from September 1993 to August 1995 and evaluated the efficacy of the angled blade plate as one of the fixation devices used. The fractures were limited to C2 and C3 fracture classifed according to the AO classification. After an average follow-up of 13 months (range, 9 to 24 months), all of the fractures had healed. Postoperatively, the arc of flexion was limited between 90degrees and 125degrees in eight, normal arc in five, and severely restricted arc of joint motion was present unexceptionally in three patients with deep infection. In angular deformity, average 5.8degrees of valgus and 2.4degrees posterior angulation were showed. The functional results by Sanders-Swiontkowski-Rosen-Helfet rating system were showed excellent in 3, good in 7, fair in 3, and poor in 3 cases. The overall results were seen to be excellent to good in ten cases (62.5%) but in twelve patients using the angled blade plate, excellent to good results were showed 10 patients (83.3%). We attribute the favorable results in our series to restoration of the articular surface through the modified extensile approach, sufficient stable fixation using the angled blade plate with conforming to the concept of bridge plate, routinely performing the bone graft for medial buttress and bone healing, and early mobilization of the extremity.

We noticed a group of thoracolumbar and lumbar spine fractures showing a unique fracture pattern that consisted of 1) superior disc injury, 2) crush fracture of the upper half of the vertebral body, 3) sagittal fracture of the lower half of the vertebral body, 4) bone fragments in the spinal canal, and 5) lamina fracture. Some of these fracture patterns were present in type B burst fracture of Denis classification. The purpose of this study was to compare the difference between crush-cleavage fracture and type B burst fracture in the viewpoint of neural canal involvement and neurologic status, and functional outcome with surgical treatment. Ten cases were identified as crush-cleavage fractures in 22 type B burst fractures during a 5 year period from Mar. 1989 to Jun. 1993 at the Department of Orthopedic Surgery of Chonbuk National University Hospital. Four out of 10 crush-cleavage fractures and 4 out of 12 type B burst fractures were paraparetic. Crush-cleavage fracture must be an unstable thoracolumbar comminuted fracture, but there were no significant differences in the neural canal involvement, incidence of neurologic deficit, and in the functional outcome, compared with type B burst fracture (P>0.05). It could be classified as a progressed form of type B burst fracture in Denis classification, or as a burst-split fracture in Magerl classification in the anatomical viewpoint. In conclusion, crush-cleavage fracture must be a variant of burst fracture.

As the newly reconstructed nipple tends to be flattened, especially if submitted to pressure, prudent dressings using various protective devices as a physical support against pressure on a new nipple is important. We used a breathing bag connecting tube as a protective device in nipple reconstruction. A breathing bag connecting tube recycled was cut and trimmed at 1cm above the height of the reconstructed nipple. Before stitch out, the newly reconstructed nipple with a local flap was dressed and protected in this way for 10 days after surgery. After stitch out, patients learnt how to manage the new nipple at home. The sole means of nipple dressing was affixing the breathing bag connecting tube with adhesive tape. Two patients had worn the tube for two months with the best compliance. Owing to the soft composition of the tube material, it is possible for a surgeon to have an easy cutting and trimming of the tube at appropriate heights as well as for a patient to show better compliance yielding better results. The cost factor is another advantage.

Background:
Femoral neck stress fractures (FNSFs) are rare but potentially disabling injuries if the diagnosis is missed or delayed and proper treatment is not provided. The aim of this study was to investigate and describe the characteristics and clinical course of FNSFs in South Korean male military recruits.
Methods:
Between May 2015 and October 2019, 16 fractures in 12 young male military recruits were reviewed. The characteristics of the fractures were ascertained by detailed analysis of the history and clinical course, as well as radiographs, bone scintigrams, and magnetic resonance images.
Results:
The median duration between endurance training and the development of hip pain was 5 weeks, while the median duration of pain before the patient sought medical attention was 3 weeks. Four patients (33.3%) exhibited bilateral fractures, and concomitant lesions involving the proximal tibia were found in 3 patients (25%). Fourteen of the 16 fractures (87.5%) were compression-type fractures, and surgery was performed for 7 hips. Complete union without malunion or osteonecrosis was achieved in all cases, and all cadets returned to their full activity levels in an average of 10 weeks.
Conclusions
We observed excellent prognosis of FNSFs. Our report highlights the importance of early reporting, detection, and treatment regarding the challenging management of FNSFs. When a military recruit reports hip pain, a FNSF should be considered; furthermore, the bilaterality of the fracture and the presence of concomitant lesions should also be investigated.

Journal of Korean Academy of Fundamental Nursing 2023;30(1):125-135
Purpose:
This study was to identify nurses’ intentions for COVID-19 vaccination in 2022.
Methods:
A questionnaire survey was conducted among 222 nurses in Korea. The collected data were analyzed using the independent t-test, one-way analysis of variance, the Wilcoxon rank sum test, Pearson’s correlation coefficients, and multiple regression analysis.
Results:
The score for intention to be vaccinated against COVID-19 in 2022 was 2.70 points on a 5-point scale, significantly lower than in 2020 (3.02 points on a 5-point scale). The average score for knowledge related to COVID-19 was 7.22 out of 10 points. Positive correlations were found between the intention for COVID-19 vaccination in 2022 and preventive health behavior, as well as between nurses’ intentions for COVID-19 vaccination in 2022 and 2020. The factors affecting nurses’ intentions for COVID-19 vaccination in 2022 were preventive health behavior (β=.11, p=.045) and nurses’ intentions for COVID-19 vaccination in 2020 (β=.65, p<.001). This model showed a significant explanatory power of approximately 45% (F=36.88, p<.001) for the COVID-19 vaccination intention in 2022.
Conclusion
This result points to the importance of managing nurses’ preventive health behaviors to promote COVID-19 vaccination uptake. Nurses’ vaccination intentions are an important issue for the safety of both nurses and patients. A safe vaccination environment and national policy should be prepared to reduce nurses' hesitations about COVID-19 vaccination.

BACKGROUND: Ischemic preconditioning(IP) is known to be effective in the protection of myocardial necrosis, arrhythmia, and the restoration of the myocardial function in the ischemia-reperfusion state of the heart. However the exact mechanism is not clearly understood. The purpose of this study was to elucidate the trigger mechanism of IP on the restoration of the myocardial function after ischemia-reperfusion. MATERIAL AND METHOD: By connecting a Langendorff perfusion apparatus with an isolated heart of a rat, the normal temperature of the heart was maintained. The experiment was conducted in seven groups, which were divided according to the preconditioning stimuli and blockage methods: Group I(n=10) was a group without IP, Group II(n=10) a group of three-minute IP, Group III(n=10) a group of PEIP, Group IV(n=10) a group of clonidine IP, Group V(n=10) a group of IP after reserpine, Group VI(n=10) a group of PE & prazosin IP, and Group VII(n=10) a group of clonidine & yohimbine IP. Hemodynamic parameters of DP, LVEDP, +/-dP/dT and the changes of perfusion in the coronary artery were evaluated. RESULT: Developed pressure and +dP/dT changed per unit time. After 20 minutes of reperfusion, those of Group II and III were 63.1+/-3.7%, 64.8+/-4.6% and 64.5+/-4.6%, 63.8+/-4.4%, which improved more significantly than those of Group I(P<0.05). However, there were no significant differences between the Groups V and VI, and Group I. CONCLUSION: The Brief ischemic preconditioning and pharmacological preconditioning using alpha-receptor sympathomimetics have protecting effects on the restoration of myocardial function after reperfusion. And the protecting effect of preconditioning seems to be related to sympathetic neurotransmitters and to the selective action of the alpha1-adrenergic receptor.

This is a clinical study of I131 Rose Bengal liver scanning on 17 in-patients with jaundice hospitalized at Severance hospital from October 1969 to March 1976. And we observed following results. 1) In 13 patients, the liver scanning showed complete biliary obstructive pattern, in 2 patients partial obstruction and two had space occupying lesions. Of the 13 patients with complete obstruction, 7 cases had biliary atresia and 6 cases.had neonatal hepatitis. We conclude that the obstructiive pattern of liver scanning does not always mean biliary atresia. 2) The quantitative calculation of the dye excretion in stool at 72 hours after IV infusions was made and only 0.447% of dye was excreted at 48 hours in biliary atresia. In 2 patients with hepatitis, the amount were 16.2% and 26.5% respectively. The quantitative study of radioactive dye excretion should be followed further evaluation. 3) Particularly in the patient with choledochal cyst and hepatoblastoma, the liver scanning was very helpful as it provided not only diagnostic information but also the anatomic site and size of the pathologic lesion.

Porcine reproductive and respiratory syndrome virus (PRRSV), a member of the genus Arterivirus in the family Arteriviridae, is the most important viral pathogens in swine industry worldwide. Here, we have investigated 5' and 3' cis-acting RNA elements required for PRRSV genome replication. Using the infectious PRRSV cDNA, we have manipulated the genomic RNA to generate mutant genomic RNAs, transfected these mutants into susceptible MARC-145 cells, and examined the competence of RNA replication. We found three genetic factors that were essential for viral replication. First, the cap structure present at the 5'-end of the genome was absolutely required for RNA replication. Secondly, polyadenylation of the genomic RNA at the 3'-end was also essential for RNA replication. Thirdly, approximately 100-nucleotide region just upstream of the N protein-coding region was crucial for genomic RNA replication. Taken together, our findings indicate that replication of PRRSV genomic RNA requires three important cis-acting RNA elements: 5' cap structure, 3' poly(A) motif, and an internal sequence of about 100 nucleotides. Further investigation is needed to elucidate the molecular mechanism(s) of how these elements act on PRRSV genome replication.
