Background: Optimal management of advisory implantable cardioverter defibrillator (ICD) leads has not been established. Several studies were reported concerning the lead extraction of advisory ICD leads, but the implant duration of those studies was short. We estimated the efficacy of lead extractions of advisory ICD leads with a relatively longer duration in Japanese patients., Methods: We retrospectively analyzed 28 patients who underwent a lead extraction at Kokura Memorial Hospital and Tokyo Medical and Dental University Hospital [Fidelis (Medtronic, Minneapolis, MN, USA): n=19, Riata (St. Jude Medical, Sylmar, CA, USA): n=8, Isoline (SORIN CRM SAS, Clamart, France): n=1]. The mean implant duration was 63.3±19.3 months. The indications were device related infections in 3, electrical lead failures in 18, electrical lead failures and venous obstructions in 3, and prophylactic reasons in 4 patients. Inappropriate shocks because of electrical lead failures were observed in 9 patients., Results: Complete removals were achieved of all 28 advisory leads. In 23 out of 28 patients, new ICD leads were implanted during the same procedure. In one patient, open chest surgery was performed for a hemothorax that occurred during a new ICD lead implantation just after successfully removing the advisory ICD lead. There were no other major or minor complications., Conclusion: Transvenous extractions of advisory ICD leads with relatively long implant duration were performed with a high success rate and low complication and mortality rate in Japanese patients., (Copyright © 2018 Japanese College of Cardiology.

Objective: The aim of this study was to clarify the state of pain management in Japanese patients with advanced cancer who initiated opioid therapy in an outpatient setting., Methods: Interview surveys using questionnaires were conducted and medical records were reviewed. Pain relief was defined as >33% decrease in worst pain intensity score, and significance of early pain relief was investigated in terms of changing self-efficacy for activities of daily living (ADL). Factors related to early pain relief were also investigated., Results: The study was conducted between June and December 2003, on 20 patients (13 women, 7 men; mean age, 59 years). Compared to score at initiation of opioid administration (Numerical Rating Scale, 8.3 +/- 1.3), pain relief was generally insufficient at 2 weeks (early pain relief ratio was only 42%). Patients with sufficient pain relief at 2 weeks displayed significant improvements in numerous ADL functions and symptom-coping efficacy (p = 0.037), confirming the importance of early pain relief. Early pain relief was associated with high frequency of hospital visits before opioid administration and absence of sudden excavation within the first 2 weeks., Significance of Results: Result of this study indicated insufficient pain relief at an outpatients setting with advanced cancer patients. In the meantime, patients had who their pain decrease after 2 weeks also had improved ADL and self-efficacy at the same time. These findings suggest that to achieve early pain relief in an outpatient setting, clinical staff must assess pain earlier and inform patients of possible breakthrough pain following opioid administration and available treatments for such occurrences.
