    BACKGROUND: Chemical coping is an inappropriate method for dealing with stress through the use of opioids; it is considered the stage prior to abuse and dependence. In patients with cancer, it is important to evaluate the risk of chemical coping when using opioids. There are some pediatric opioid use-related tolerances and addictions; however, no mention of chemical coping has been found. CASE PRESENTATION: We present a case of an 11-year-old Japanese boy with acute lymphocytic leukemia. After transplantation, he complained of abdominal and articular pain, which are considered as symptoms of graft-versus-host disease; thus, opioid therapy was initiated, and the dose was gradually increased for pain management, resulting in a high dose of 2700 μg/day of fentanyl (4200-4700 μg/day including the rescue dose). After switching from fentanyl to oxycodone injections, he continued to experience pain, and there was no change in the frequency of oxycodone rescue doses. Physically, his pain was considered to have alleviated; thus, there was the possibility of mental anxiety resulting in the lowering of pain threshold and the possibility of chemical coping. Mental anxiety and stress with progress through schooling was believed to have resulted in chemical coping; thus, efforts were made to reduce the boy's anxiety, and opioid education was provided. However, dose reduction was challenging. Ultimately, with guidance from medical care providers, the opioid dose was reduced, and the patient was successfully weaned off opioids. CONCLUSIONS: When chemical coping is suspected in pediatric patients, after differentiating from pseudo-addiction, it might be necessary to restrict the prescription for appropriate use and to provide opioid education while taking into consideration the emotional background of the patient that led to chemical coping.

    Complex regional pain syndrome (CRPS) accompanies allodynia. Allodynia impairs the quality of life in chronic pain patients and is often difficult to treat. It has been suggested that yokukansan has an anti-allodynic effect. In this case report, shichimotsukokato was administered to a patient with CRPS who could not continue to take yokukansan. Shichimotsukokato provided the same anti-allodynic effect as yokukansan. Shichimotsukokato contains chotoko, which is the active constituent leading to anti-allodynia action in yokukansan. This case suggests that shichimotsukokato may offer similar anti-allodynia effect as yokukansan.

    Many patients with autosomal dominant polycystic kidney disease (ADPKD) have some sort of pain, and a stepwise approach has been proposed as a management method for it. We managed the pain of an ADPKD patient who had combined multiple hepatic cysts. Since tramadol was effective for the pain, which was also relieved by an epidural block using a low concentration of a local anesthetic, we diagnosed that the pain was mainly derived from internal organs. We prescribed opioids and the pain was relieved. We need to pay attention to the possibility of an increase in renal cysts due to enhanced vasopressin action by opioids, but opioids may be effective for the visceral pain of ADPKD.
