Objectives: The purpose of this study was to report Four cases of Failed Back Surgery Syndrome (FBSS) patients after spinal fusion surgery who showed significant improvement in pain and function with Complex Korean medical treatment. Methods: This study was a retrospective observational study. We reviewed medical records of Four patients with lumbar pain or radiating leg pain, who have received spinal fusion surgery in the past. All Four patients took complex treatments of Mokhuri Neck and Back hospital which involes Acupuncture, Pharmaco-acupuncture, Gangchuk herbal medicine, Chuna and Physical therapy during about four-week of admission treatment. Visual Analogue Scale (VAS), Oswestry disability index (ODI), Pain Free Walking Distance (PFWD) scores were assessed before and after treatments. Results: The average of hospitalization period was 28.5 days. Mean VAS scores decreased from 6.5 to 2.3, Oswestry Disability Index (ODI) scores decreased from 56.25 to 38.25 and Pain Free Walking Distance (PFWD) also improved from 10m to 166.6m. Conclusion: This study implies that a combination of Korean medical treatments might be effective in relieving pain, and improving the functional status of FBSS patients. Further studies are needed to fully understand the mechanisms underlying the effects.

Objectives: The purpose of this study is to retrospectively evaluate the postoperative complication rates for absorbable type-I collagen sponge (Ateloplug; Bioland) use in third molar extraction. Materials and Methods: From January to August 2013, 2,697 total patients undergoing third molar extraction and type-I collagen sponge application in the Department of Oral and Maxillofacial Surgery at Yonsei University Dental Hospital (1,163 patients) and Dong-A University Hospital (1,534 patients) were evaluated in a retrospective study using their operation and medical records. Results: A total of 3,869 third molars in 2,697 patients were extracted and the extraction sockets packed with type-I collagen sponges to prevent post-operative complications. As a result, the overall complication rate was 4.52%, with 3.00% experiencing surgical site infection (SSI), 1.14% showing alveolar osteitis, and 0.39% experiencing hematoma. Of the total number of complications, SSI accounted for more than a half at 66.29%. Conclusion: Compared to previous studies, this study showed a relatively low incidence of complications. The use of type-I collagen sponges is recommended for the prevention of complications after third molar extraction.

Purpose: This study aims to describe the characteristics of safety incidents and factors associated with injury for patients with Home Mechanical Ventilation (HMV) at the hospital. Methods: This is a retrospective study. Data were collected from the work log of respiratory home care nurses and the patients' electronic medical records were investigated. In order to compare group differences, independent t-test and χ² test were used. Associated factors with injury development were identified by generalized mixed modeling analysis controlling for age and gender. Results: A total of 304 patients on HMV were included in this study, among which 129 (42.4%) experienced 352 HMV-related incidents. Mean frequency of incidents for each patient was 5.11±3.98, ranged from 1 to 15 times. In 19.0% of the incidents, injury was developed. Types of incident and persons involved in the incidents were significantly associated with the patient's injury. In the case of the safety incidents, patient's injury was significantly higher in accidents caused by respiratory circuit problems compared to those caused by problems with the ventilator operation by the medical staff (coefficient=1.25, p=.020). In addition, in the case of those involved in the safety incidents, patient's injury was significantly higher in the accident caused by the patient family members or caregivers than that caused by the medical personnel (coefficient=1.25, p=.019). Conclusion: In order to minimize injury caused by incidents in patients with HMV, hospitals need to provide systemic education to their medical staff and caregivers to enhance awareness of the importance of reporting and safety management.

Aprepitant is a substance P/neurokinin-1 (NK1)-receptor antagonist that was approved in 2003 for prevention of CINV. In addition, updated anti-emetic guidelines that include the aprepitant regimen have been published by NCCN and ASCO. However there is scarce clinical data in Korea. The prospective study was performed to evaluate the prevention of high dose cisplatin induced nausea and vomiting in all patients who started high-dose cisplatin-based chemotherapy at our hospital. We checked the nausea severity and vomiting episodes by calling patients within 4 to 5 days after chemotherapy. The retrospective study was performed to compare the prevention of CINV in solid tumor patients who switched their anti-emesis regimen from the standard regimen to the aprepitant regimen. In aprepitant regimen, aprepitant was added to the same anti-emetic regimen used during previous cycles. We checked the nausea, vomiting grades and adverse events in electronic medical records (EMR). In prospective study, 195 patients were included in the analysis. 88.2% of patients achieved a complete response (no emesis and no rescue therapy). In retrospective study, 54 patients were reviewed. With aprepitant regimen, nausea and vomiting grades were improved in 22 patients (40.7%) and in 9 patients (16.7%), respectively. Compared with standard regimen, addition of aprepitant provided superior prevention against CINV in Korean patients receiving highly emetogenic cisplatin-based chemotherapy. Moreover, aprepitant significantly prevented CINV in patients who received the standard regimen to prevent CINV in previous chemotherapy cycles.

Objective: Persons with chronic stroke fall more often than healthy elderly individuals. The Timed Up and Go test (TUG) is used as a fall prediction tool, but only provides a result for the total measurement time. This study aimed to determine the optimal cut-off values for each of the 6 components of the TUG. Design: Retrospective study. Methods: Thirty persons with chronic stroke participated in the study. TUG evaluation was performed using a wearable miniaturized inertial sensor. Sensitivity, specificity, and predictive values were calculated using the Receiver Operating Characteristic (ROC) curve analysis for the measured values in each section. Optimal values for fall risk classification were determined. Logistic regression analysis was used to investigate the risk of future falls based on TUG. Results: The cut-off values of the 6 sections of the TUG were determined, as follows: sit-to-stand >2.00 seconds (p<0.05), forward gait >4.68 seconds (p<0.05), mid-turn >3.82 seconds (p<0.05), return gait >4.81 seconds (p<0.05), end-turn >2.95 seconds (p<0.05), and stand-to-sit >2.13 seconds (p<0.05). The risk of falling increased by 2.278 times when the mid-turn value was >3.82 seconds (p<0.05). Conclusions: The risk of falls increased by 2.28 times when the value of the mid-turn interval exceeded 3.82 seconds. Therefore, when interpreting TUG results, the predictive accuracy for falls will be higher when the measurement time for each section is analyzed, together with the total time for TUG.

Background: The purpose of this study was to investigate the clinical efficacy of Korean medicine combination treatments for recurring back pain after medical procedures. Methods: This was a retrospective study performed on 311 patients admitted to Daejoen Jaseng hospital who were diagnosed with lumbar spine herniated intervertebral discs. The patients were divided into 2 groups according to whether or not they had undergone at least one medical procedure on the lumbar spine. They were assessed with Numeric Rating Scale (NRS), Oswestry Disability Index (ODI) and EuroQol-5 Dimensions Index (EQ-5D) before and after treatment. Results: Patients who experienced a medical procedure on the lumbar spine in the prehospital phase (Group A), statistically significantly improved EQ-5D and ODI scores. The NRS scores also decreased however it was not statistically significant. Patients who had not undergone a medical procedure on the lumbar spine in the prehospital phase (Group B) had statistically significantly improved ODI and NRS scores. The average EQ-5D score decreased however, there was no statistically significant difference before and after scores in Group B. There was no statistically significant difference in variation in EQ-5D, ODI, and NRS scores before and after treatment between the groups. Conclusion: The results of this study indicated that even after a bilateral procedure and surgery, when pain in patients with lumbar spine herniated intervertebral disc did not decrease, (as in failed back surgery syndrome), Korean medicine combination treatment of postoperative pain was helpful and there was improvement in daily life.

Objectives: In South Korea, traffic accident victims can be treated under automobile insurance coverage. Korean medicine (KM) clinics have reported the largest number of automobile insurance fee claims among medical institutions. This study investigated the status of the KM automobile insurance system in a single KM clinic. Methods: We retrospectively surveyed the medical charts of 342 traffic accident patients treated at the Jisung KM clinic between January 2009 and June 2017. Results: Most of the patients were men and in their 30s. The most common method of locating the clinic was an internet search. The most common traffic accident type was collision between vehicles (83.63%), with 70.76% of patients visiting during the most acute phase. The major disease codes included S434, M4836, F072, S0600, and S3350. The most frequent treatment period was within 1 month of the accident, and most patients received 10 or fewer treatments. The mean treatment duration and number of treatments were 37.68 ± 45.11 days and 11.68 ± 10.63 treatments, respectively. The initial pain numerical rating scale (NRS), 7.32 ± 0.96, decreased to 3.57 ± 1.40 at the end of treatment, with a symptom improvement score of 1.87 ± 0.60. Regarding sex, age, disease duration, location at the time of the accident, presence of additional and psychological symptoms, and chuna, there were statistically significant differences in treatment duration and number of treatments. A higher number of treatments and the longer treatment duration was associated with a higher initial NRS, lower post-treatment NRS, and better improvement score. Since the introduction of traffic accident (TA) pharmacopuncture, the rate of use of a single type of pharmacopuncture increased; however, no significant differences in treatment duration and number, NRS before and after treatment, and improvement score were observed between treatment groups before and after TA pharmacopuncture. No adverse reactions were observed for any treatment. Conclusion: This study confirmed the previous findings of a high treatment effect of KM under automobile insurance. We also observed significant correlations based on a detailed medical status, which may explain the increasing use of KM in the automobile insurance system. Additional multi-center studies in different regions are needed.

This study focused on the literary world of T. Tolstaya, a Russian writer who takes a crucial position in contemporary Russian literature, drawing upon the wrier's a couple of short stories. 'Youth' is a key motive encompassing all works of Tolstaya, so that it becomes the poetic keynote among her literary works. In order to examine such distinctions of the main characters' world awareness in their youth as shown in Tolstaya's literary works, Chapter 2 of this paper paid a special attention to the analyse of her representative works such as "Sitting on a Golden Terracing Stone" and "Meeting with a Bird", and expressed potential implications of youth with mimetic imagination for her. For Tolstaya, youth is perceived as a paradise but original imagination of youth gradually fades away in adult and ends up with a lost paradise. This is why Tolstaya uses poetic means based on nostalgia for youth like paradise and literary motto for recovery of imagination in youth. In this regard, this study particularly examined the retrospective prologue resisting the power of time as well as different fictional characters living in her own fantastic world. As a result, this study draws a conclusion that such longing and nostalgia for youth and lost paradise as delineated by Tolstaya through retrospective prologue and characters speak for an existential speculation that explores any profound implication of afflictions in reality of human life, rather than focusing on the painful reality of human life which consists of honest dialogues with realities like 'darkness' and 'pain.' In addition, this study, complying with Zolotonosov's ideas which deal with and define Tolstaya's literary works as a shabby and humble box invisibly containing a full wealth of precious jewels inside, sheds a new light on the writer's literary world.

Objectives: This study sought to investigate the association between the systemic intake of proton pump inhibitors (PPI) and the early failure of dental implants. Materials and Methods: A retrospective cohort study involving 1,918 dental implants in 592 patients (69 implants in 24 PPI users and 1,849 implants in 568 nonusers, respectively) was conducted. The effect of PPI intake on the osseointegration of dental implants was evaluated using patientand implant-level models. Results: Among 24 PPI users, two patients experienced implant failure, one of whom had three and the other of whom had one failed implant, respectively. Thus, the rate of failure for this population was 8.3%. Separately, 11 nonusers each experienced one implant failure, and the failure rate for these patients was 1.9%. Fisher's exact test revealed statistically significant differences between PPI users and nonusers at the implant level (P=0.002) but failed to show any significance at the patient level (P=0.094). The odds of implant failure were 4.60 times greater among PPI users versus nonusers. Dental implants that were placed in patients using PPIs were found to be 4.30 times more likely to fail prior to loading. Conclusion: The findings of this study suggest that PPI intake may be associated with an increased risk of early dental implant failure.

Purpose: The purposes of this study were to determine the changes in the pattern of patients who were transferred to the emergency room through inter-hospital private institutions and to determine how long transport takes following the COVID-19 outbreak. Methods: This retrospective observational study analyzed the emergency medical services reports of private institutions following the COVID-19 outbreak in South Korea. The study was conducted in Busan between January 19, 2019 and January 18, 2020, and between January 19, 2020 and January 18, 2021. Results: Upon comparing the patient transport times during the "Pre-COVID-19 period" and "COVID-19 period," a significant delay was noticed in the preparation for transfer of patients during the "COVID-19 period" (p<.05). There were significantly more patients with respiratory infections and patients who complained of general symptoms during the "COVID-19 period." Moreover, there was a higher frequency of patients who were transferred to a 'Level I' emergency room during the "COVID-19 period" compared to during the "Pre-COVID-19 period" (p<.05). Conclusion: Following the COVID-19 outbreak, there is a delay in patient transport to the emergency room through private institution inter-hospital transport and an increase in the number of patients complaining of respiratory infection symptoms. Thus, emergency medical services need additional administrative and economic support to transport infected patients.
