Amiodarone is one of the most commonly prescribed antiarrhythmic drug for almost all atrial or ventricular arrythmias. Amiodarone-induced pulmonary toxicity (APT) was first described in 1980 and has potentially serious side effects that are believed to develop in 5% of patients. In general, APT occurs only when high amiodarone doses are used for a long time. However, during short-term therapy of amiodarone, APT is rarely reported. In this report, we describe a case of amiodarone-induced pulmonary toxicity after a short course of amiodarone therapy for atrial fibrillation.

Great effort has been exerted to redesign the supply chain network as a means to improve corporate competitiveness. In this study, we present a mathematical model and a solution system to help redesign corporate logistics networks. The objective of the model is to minimize total logistics costs. We applied the solution system to real problem cases. We use the model and the concept to develop decision support system that is based on C++ with the use of CPLEX callable library as a solution engine. We tested and verified the DSS for redesigning the network of a large Korean electronics company. Through various scenario analyses, we recommend to redesign their supply chain network that demonstrates the possibility of substantial logistics cost savings.

Purpose: After creating a new emergency medical service in Tangalle, Sri Lanka, this analysis intends to determine the changes of satisfaction related to the facility and medical care givers. With this information, an assessment regarding the role of PCU (preliminary care unit) and the contribution of PCU is made possible. Furthermore, the baseline data can be used for further development. Methods: PCU survey was conducted before and after the establishment on site at Tangalle, Sri Lanka. Patients were surveyed based on a five point Likert scale. Patients were asked to rate their level of satisfaction with doctors, facilities, and the environment in the hospital. Results: After the establishment of PCU the number of patients increased by 270% (from 11,496 patients in Year 2011 to 31,120 patients in Year 2014). The number of patients returning home also increased from 2412 to 14,315. Prior to the establishment of PCU, the choice of visiting emergency centers was based on the following order: Kindness of doctors, quality of medical treatment, kindness of nurses. After the establishment of PCU, the choice of visiting emergency centers was changed: From ranking 7th to 2nd, cleanliness of hospital facilities. From ranking 19th to 9th, amenities. Satisfaction ratings regarding the patients’ perspective of doctors have not changed. However, the satisfaction ratings of the following have changed statistically: From ranking 9th to 2nd, admission process was simple. From ranking 8th to 3rd, PCU had proper medical devices and equipment. From 6th to 5th, received the results of tests quickly. On the other hand, the satisfaction rating for waiting time was pushed back from 7th to 10th. Conclusion: After establishment of the PCU, positive indications were: increase in the number of patients, increase in the capacity to receive patients, and increase in satisfaction with the facility. The level of satisfaction regarding the medical staff was unchanged. The level of satisfaction regarding waiting time was decreased.
