Background:
The coronavirus disease 2019 (COVID-19) pandemic has caused significant changes. This study aimed to investigate the impact of COVID-19 on patients with chronic pain.
Methods:
Patients with chronic pain from 23 university hospitals in South Korea participated in this study. The anonymous survey questionnaire consisted of 25 questions regarding the following: demographic data, diagnosis, hospital visit frequency, exercise duration, time outside, sleep duration, weight change, nervousness and anxiety, depression, interest or pleasure, fatigue, daily life difficulties, and self-harm thoughts. Depression severity was evaluated using the Patient Health Questionnaire-9 (PHQ-9). Logistic regression analysis was used to investigate the relationship between increased pain and patient factors.
Results:
A total of 914 patients completed the survey, 35.9% of whom had decreased their number of visits to the hospital, mostly due to COVID-19. The pain level of 200 patients has worsened since the COVID-19 outbreak, which was more prominent in complex regional pain syndrome (CRPS). Noticeable post-COVID-19 changes such as exercise duration, time spent outside, sleep patterns, mood, and weight affected patients with chronic pain. Depression severity was more significant in patients with CRPS. The total PHQ-9 average score of patients with CRPS was 15.5, corresponding to major depressive orders. The patients’ decreased exercise duration, decreased sleep duration, and increased depression were significantly associated with increased pain.
Conclusions
COVID-19 has caused several changes in patients with chronic pain.During the pandemic, decreased exercise and sleep duration and increased depression were associated with patients’ increasing pain.

Complex regional pain syndrome (CRPS) is a syndrome of pain and sudomotor or vasomotor instabilities. The perioperative pain management in CRPS patients is very important, as surgery can aggravate preexisting symptoms, especially when performed around the lesion site. Despite the increasing interest in CRPS research, little is known about the optimal perioperative treatment strategy for CRPS patients. Herein, the case of a female CRPS patient, who underwent elective surgery at the lesion site, is reported. As a preemptive analgesia, the patient was satisfactorily managed with two weeks of patient-controlled epidural analgesia, initiated 2 days prior to surgery. The techniques for the prevention of perioperative pain, including preemptive analgesia, as well as its importance, are discussed.

This study was to determine the effects of allogenicumbilical cord blood (UCB)-derived mesenchymal stemcells (MSCs) and recombinant methionyl humangranulocyte colony-stimulating factor (rmhGCSF) on acanine spinal cord injury model after balloon compressionat the first lumbar vertebra. Twenty-five adult mongreldogs were assigned to five groups according to treatmentafter a spinal cord injury: no treatment (CN); salinetreatment (CP); rmhGCSF treatment (G); UCB-MSCstreatment (UCB-MSC); co-treatment (UCBG). The UCB-MSCs isolated from cord blood of canine fetuses wereprepared as 10(6) cells/150microl saline. The UCB-MSCs weredirectly injected into the injured site of the spinal cord andrmhGCSF was administered subcutaneously 1 week afterthe induction of spinal cord injury. The Olby score,magnetic resonance imaging, somatosensory evokedpotentials and histopathological examinations were used toevaluate the functional recovery after transplantation. TheOlby scores of all groups were zero at the 0-week evaluation.At 2 week after the transplantation, the Olby scores in thegroups with the UCB-MSC and UCBG were significantlyhigher than in the CN and CP groups. However, there wereno significant differences between the UCB-MSC andUCBG groups, and between the CN and CP groups. Thesecomparisons remained stable at 4 and 8 week aftertransplantation. There was significant improvement in thenerve conduction velocity based on the somatosensory evokedpotentials. In addition, a distinct structural consistency ofthe nerve cell bodies was noted in the lesion of the spinalcord of the UCB-MSC and UCBG groups. These resultssuggest that transplantation of the UCB-MSCs resulted inrecovery of nerve function in dogs with a spinal cord injuryand may be considered as a therapeutic modality for spinalcord injury.

BACKGROUND: Steroid injections are commonly used in pain clinics to relieve pain and treat inflammation. In Korea, these steroid injections are well known as ‘ppyeojusa’, which means to inject into the bone in Korean. Some patients often have a negative perception of this treatment method due to inaccurate information about the treatment and side effects of steroids. The purpose of this study is to investigate patients’ perception and knowledge of ppyeojusa. METHODS: A questionnaire about ppyeojusa was completed by patients who visited one of the pain clinics in nine university hospitals, from August 1 to September 10, 2017. RESULTS: Three-hundred seventy-four patients completed the survey. Eighty-five percent of patients had had ppyeojusa, and 74% of the respondents had heard of ppyeojusa from the mass media, friends or relatives. Only 39% of the patients answered that this injection was safe without side effects if properly spaced. Of the patients surveyed, 21% responded that ppyeojusa are “injections into the bone”; while 15% responded that ppyeojusa are “terrible injections that melted ‘the bone if used a lot’”. Half of the patients did not know what the active constituent is in ppyeojusa. If steroid injections are advised by the pain specialists, 89% of the patients would consent. CONCLUSIONS: Most pain clinic patients have heard of ppyeojusa. Most patients obtained information about ppyeojusa from mass media, rather than their physicians. Therefore, it is likely that most patients have inaccurate knowledge.

Background:
Complex regional pain syndrome (CRPS) is an intractable pain disease with various symptoms. Here, we investigated the disease status, work life, sleep problems, medical insurance, economic status, psychological problems, and quality of life (QOL) of CRPS patients.
Methods:
CRPS patients from 37 university hospitals in South Korea were surveyed.The survey questionnaire consisted of 24 questions on the following aspects of CRPS patients: sex, age, occupation, cause of injury, activities of daily living (ADL), pain severity, sleep disturbance, level of education, economic status, therapeutic effect, and suicidal ideation. Additionally, the abbreviated World Health Organization Quality of Life (WHOQOL-BREF) questionnaire, consisting of 26 questions, was used to identify the status of QOL.
Results:
A total of 251 patients completed the questionnaire. According to the survey, 54.2% patients could not perform ADL on their own. Over the previous week, the mean pain score was 7.15 ± 1.78 (out of a total of 10 points); 92.1% of patients had sleep disorders and 80.5% had suicidal ideation, with most patients suffering from psychological problems. The average for each domain of WHOQOL-BREF was as follows: 21.74 ± 14.77 for physical, 25.22 ± 17.66 for psychological, 32.02 ± 22.36 for social relationship, and 30.69 ± 15.83 for environmental (out of a total of 100 points each). Occupation, ADL, sleep time, therapeutic effect, and suicidal ideation were statistically correlated with multiple domains.
Conclusions
Most patients had moderate to severe pain, economic problems, limitations of their ADL, sleep problems, psychological problems, and a low QOL score.

Background:
Chronic pain affects approximately 22% of the world’s population. Opioids can be useful in chronic pain management. However, some patients have negative perception of opioids. The purpose of this research was to evaluate patients’ perception about opioids and investigate problems associated with prescribing and taking opioids in South Korea.
Methods:
Patients who visited a pain clinic in 14 university hospitals of South Korea from September through October 2018 were asked to complete anonymous questionnaires about taking opioids.
Results:
Of the 368 patients that were surveyed (female 53.3%, male 46.7%), 56.8% were prescribed opioids. In the opioid group, 92.8% patients had heard of opioids from their doctor and 72.6% of them had a positive perception about opioids. The side effects associated with opioid use were constipation (35.4%), dizziness (24.6%), nausea and vomiting (17.4%), dysuria (6.2%), and addiction (2.0%). In the no opioid group, the primary sources of information about opioids were doctors (49.2%), mass media (30.8%), and the internet (16.2%). The main reasons why 39.0% patients did not take opioids were fear of addiction (57.7%) and side effects (38.5%). There were 71.5% and 60.9% patients in the opioid and no opioid group, respectively, who wished to take opioids when their numeric rating scale pain score was ≥ 7.
Conclusions
Perception of opioids among patients who take them was either neutral or positive. However, 39.0% patients who have not been prescribed opioids did not want an opioid prescription, citing fear of addiction and side effects as the primary reasons.

Background:
Use of opioids for chronic intractable pain is increasing globally, and their proper use can improve patients’ quality of life. In contrast, opioid use disorders, such as abuse or addiction, caused by prescribing opioids, are a worldwide issue. This study aimed to understand current opioid prescribing patterns and pain physicians’ experiences with opioid use in South Korea.
Methods:
Pain physicians in 42 university hospitals in South Korea were asked to complete anonymous questionnaires regarding opioid prescriptions.
Results:
A total of 69 surveys were completed. Most pain physicians started prescribing opioids at a pain score of 7/10 and aimed to reduce pain by 50%. Most physicians (73.1%) actively explained the prescribed medications and possible side effects, and 61.2% of physicians preferred the prescription interval of 4 weeks.Immediate-release opioids were the most popular treatment for breakthrough pain (92.6%). The most common side effect encountered by physicians was constipation (43.3%), followed by nausea/vomiting (34.3%). Of the physicians, 56.5% replied that addiction and misuse prevalences were less than 5%. However, the most concerning side effect was addiction (33.0%).
Conclusions
The survey results showed that the prescribing patterns of pain physicians generally followed Korean guidelines. Physicians were most interested in the safety and effectiveness of opioid prescriptions. They were most concerned about respiratory depression and abuse or addiction. A significant number of physicians agreed that the NHIS regulations needed improvement for patient convenience and safe and effective treatment, though there were pros and cons of the NHIS restrictions on prescription conditions.
