We are reporting a rare case of a delayed hypersensitivity reaction caused by hyaluronidase allergy following a lumbar transforaminal epidural block. Using an intradermal skin test, we have provided evidence that the systemic allergic reaction resulted from hypersensitivity to hyaluronidase. To our knowledge, this is a rare case of a delayed hypersensitivity reaction to epidural hyaluronidase, comprised of an initial exposure to hyaluronidase with no subsequent allergic response in prior block followed by a subsequent delayed reaction to hyaluronidase during a second epidural block.

The complex regional pain syndrome(CRPS) is a painful and disabling disorder that can affect one or more extremities. Unfortunately, knowledge concerning its natural history and mechanism remains very limited. Many current rationales in treatment of CRPS are mainly dependent on efficacy originate in other common conditions of neuropathic pain. This article introduces various treatments for CRPS, but few studies of high methodological quality have been carried out into the effects of those treatments. I think early recognition and a multidisciplinary approach to management seems important in obtaining a good outcome.

Objectives: Because of the changing life style of Koreans, we have witnessed an increase of patients with back pain. The development of medical knowledge and technology has resulted in more numerous and better treatment methods. However, the outcomes of diverse treatments have been examined by using a few medicine-oriented measures like pain. This study aims at identifying the factors that influence the outcomes of back pain treatments by using two outcome measures (e.g., quality of life and pain). Methods: We used the questionnaire survey method for data collection. The questionnaires contained 5 categories (treatment methods, clinical conditions, exercise, quality of life and, socio-demographic characteristics). We interviewed 188 back pain patients. We used the regression analysis method to predict the quality of life or pain. Results: Surgery showed a statistically significant effect on the quality of life as well as pain. The illness period, age and exercise were turned out to be significant factors for both of the dependent variables. The social class and surgery methods showed a statistically significant effect solely on the quality of life. Conclusions: In choosing the surgical methods, doctors need to provide detailed explanations on the quality of life outcomes for each of the surgical methods to the patients.

Purpose: This study was designed to evaluate the perception of cancer in aspirants for hospice volunteer. Methods: Aspirants for hospice volunteer were surveyed by questionnaire before education of hospice program in September 2005 at Pyongan Hospice Center of Sam Anyang Hospital. The questionnaire was composed of total 28 items. Ten items were general characteristics and the remaining 18 items knowledge, attitude and practice of cancer and cancer pain. The data were analyzed by SPSS WIN 11.0 program using frequency, mean, percentage. Results: Eighty nine questionnaires were returned. There were 6 males and 83 females, and median age of aspirants was 46 years. Forty five aspirants(51%) had a cancer patient in th family or relatives and the others 44(49%) not. Forty eight(54%) had favorable attitude about modern clinical medicine for cancer treatment and the others 39(44%) unfavorable. Fifty eight(65%) had favorable attitude about complementary and alternative medicine for cancer treatment and the others 20(23%). In response to the question about 'How illness is a cancer', 25 aspirants(25%) responded to chronic disease, 42(47%) suffering incurable disease, the others 17(19%) death sentence, respectively. A number of aspirants had wrong knowledge and understanding of cancer, cancer pain and opioid analgesics. Seventy one percent aspirants feared cancer pain. Conclusion: The credibility to modern clinical medicine for cancer treatment was relatively low in aspirants for hospice volunteer compared with complementary and alternative medicine. They recognized a cancer as suffering incurable disease and death sentence than chronic disease. A number of aspirants had wrong knowledge of cancer, cancer pain and opioid analgesics. Therefore, further studies and trial will be warranted to evaluated the causes of these results and improve the credibility of modern clinical medicine for cancer treatment in general population.

This study was conducted to identify pain intensity and factors affecting pain intensity in patients with advanced cancer. Data were collected between June 1 and September 30, 2016 using a questionnaire. The sample size was 221 patients with advanced cancer who were admitted to the oncology department or who visited the outpatient of the general hospital. Data were evaluated by descriptive and Pearson's correlation analyses, one way ANOVA, t-tests and stepwise multiple regression analysis. The mean scores of pain intensity of cancer patients were 4.23 (${\pm}1.68$) based on the average daily pain intensity. Factors influencing pain intensity were illness perception (${\beta}=.27$, p<.001), pain opioid analgesics beliefs (${\beta}=.24$, p<.001), education (middle school, ${\beta}=.24$, p=.001), economic status (${\geq_-}400$, ${\beta}=.20$, p=.001), gender (female, ${\beta}=.14$, p=.017), pain management education (${\beta}=-.14$ p=.020) and diagnosis (Pancreatic Ca, ${\beta}=.14$, p=.020). It explained 28%. Overall, the results of this study revealed that illness perception and pain opioid analgesics beliefs were important factors influencing pain intensity, but that the most important influencing factor was illness perception. Accordingly, it is necessary to develop pain management strategies that include not only pain management knowledge and pain opioid analgesics beliefs, but also illness perception.

No definitive etiology or risk factors have been identified that predispose individuals to developing complex regional pain syndrome (CRPS). We experienced two cases of CRPS developed after arterial and venous puncture which were done in regular medical work. A 35-years old female patient was suffered from pain and allodynia with swelling at right hand and wrist after radial artery puncture for monitoring of blood pressure during general anesthesia. A 24-years old male patient had pain and swelling with allodynia at the right fingers and arm after median cubital vein puncture for blood sampling. They did not have proper pain management as CRPS patients in the past weeks and months after their pain occurred. They were diagnosed as CRPS and started undergoing various interventional procedures, which led to improve their pain condition. Our cases suggest that CRPS could develop without any proved tissue damage in routine medical practice. In conclusion, health care workers should be educated in knowledge about the uncommon medical condition and proper consultation to pain specialist when it happens.

Painful periarticular calcification most commonly occurs within the rotator cuff of the shoulder and rarely around the elbow, hip, foot, and neck. As acute inflammatory reaction develops, severe pain, exquisite tenderness, local swelling, and limitation of motion with pain occur. In case of calcific tendinitis of the shoulder, it can be easily diagnosed according to the symptoms and with x-ray. However, in lesions of the hip, as it is a rare location and usually involves pain in the posterolateral aspect of the thigh, which can simulate radicular pain from a lumbar intervertebral disc, it could be difficult to diagnose. Hence, physicians usually focus on lumbar lesions; therefore, misdiagnosis is common and leads to a delayed management. Here, we report the case of a 30-year-old female patient with calcific tendinitis of the rectus femoris that was successfully managed with ultrasound-guided steroid injection. This study offers knowledge about the rectus femoris calcification.

Background: Chemotherapy-induced peripheral neuropathy is a major side effect of anti-cancer drugs, and our knowledge of its mechanisms is lacking. Several models for chemotherapy-induced neuropathy have been introduced. However, the outcomes of these models differ significantly among laboratories. Our object was to create a model of chemotherapy-induced neuropathy in rats with cancer. Methods: Female Sprague-Dawley rats were used. Mammary rat metastasis tumor (MRMT-1) cells were implanted subcutaneously in rats. Chemotherapy-induced peripheral neuropathy was induced by injection of cisplatin once a day for four days. The responses to mechanical and thermal stimuli were examined using von Frey filaments, acetone, and radiant heat. Results: Cisplatin (2 mg/kg/day) produced mechanical allodynia, while it did not induce cold allodynia or thermal hyperalgesia. This dose of cisplatin could work successfully against cancer. Body weight loss was not observed in cisplatin-treated rats, nor were other abnormal behaviors noted in the same rats. Conclusions: Repeated injection of intraperitoneal cisplatin induced peripheral neuropathic pain in rats. Thus, this type of rat model has broad applicability in studies related to searching for the mechanism of cisplatin-induced mechanical allodynia and agents for the treatment of neuropathic pain.

Purpose: The purpose of this study was to develop a computer decision making support system that enables nurses to utilize the computer in selecting the best decision for pain management for patients with dementia institutionalized in nursing homes. Methods: To formulate the protocol for the management of patients' pain, the researcher analyzed content of interviews with 30 nurses in three nursing homes and an expert group. A decision support computer program was formalized based on existing protocols. To evaluate the effectiveness and applicability of the system, analysis of data on patient pain management and nurse satisfaction with the system were done after the formalized decision support computer program was complete. Results: The decision support computer program for pain management for institutionalized patients with dementia was finalized after adjustments following the evaluation. Nurse satisfaction with the program was moderate. It also provided opportunity to reassess thinking about pain and pain management. Conclusions: The results indicate that this program provides nurses with useful knowledge for pain management in institutionalized patients with dementia and aids in decision making in nursing practice in nursing home.

The extraction of third molars is a common task carried out at dental/surgery clinics. Postoperative pain is one of the two most common complications of this surgery, along with dry socket. Knowledge of the frequent risk factors of this complication is useful in determining high-risk patients, planning treatment, and preparing the patients mentally. Since the risk factors for postoperative pain have never been summarized before while the risk factors for dry socket have been highly debated, this report summarizes the literature regarding the common predictors of postextraction pain. Except for surgical difficulty and the surgeon's experience, the influences of other risk factors (age, gender and oral contraceptive use) were rather inconclusive. The case of a female gender or oral contraceptive effect might mainly be associated with estrogen levels (when it comes to dry socket), which can differ considerably from case to case. Improvement in and unification of statistical and diagnostic methods seem necessary. In addition, each risk factor was actually a combination of various independent variables, which should instead be targeted in more comprehensive studies.
