Nagara Medical Center introduced two computer systems that utilized data imputed into electronic medical records. The first system was used to check cancer chemotherapy prescriptions, whereas the second system was a preparation support system that facilitates precise mixing of anticancer drugs.
The prescription checking system made it possible to easily monitor the dose of anticancer drugs and dosing intervals utilizing data imputed into electronic medical records. Using this system, the time required for checking was reduced significantly compared to without using the system.
The preparation support system enables converting the dose of anticancer drugs that imputed into electronic medical records to the prepared amount automatically and checking of the amounts of drugs for drug preparations. Drugs are checked by reading a bar code attached to a vial or ampule in order to check prepared drugs are correct. The prepared amount of drug is checked by measuring the weight of a syringe used in preparation before and after preparation. Using the preparation support system, the preparation time required was prolonged significantly compared to that without using the system. However, questionnaire survey revealed that prolonged time was in the allowable range to ensure safety.
In conclusion, it is considered that the prescription checking system introduced efficient checking of prescriptions, and that the preparation support system introduced an improvement in the accuracy of preparation.

Objective: We have used therapeutic drug monitoring (TDM) analysis software to set the initial dose of vancomycin in our hospital. In contrast, the TDM guideline, in which the initial dose of vancomycin per body weight was set, was published in 2012. We looked forward with utilizing the TDM guideline in the clinical setting, after which we conducted multiple surveys to determine the important points of the TDM guideline.
Methods: We surveyed patients treated with vancomycin, in whom the initial dose was set using the TDM analysis software and the concordance rate between the vancomycin dose set with the software and that set with the TDM guideline.
Results: The concordance rate of vancomycin dose was 42.1%. The mean age of the high-dose group (vancomycin dose higher than that recommended by the TDM guideline), was younger than that of the recommended-dose group. Additionally, the mean body weight of the high-dose group was significantly lower than that of the recommended-dose group. The corrected creatinine clearance of the low-dose group was significantly lower than that of the recommended-dose group.
Conclusion: Our results suggest that when the initial dose is set after referring the TDM guideline in patients who are not very high age, and having low body weight and decreased renal function, the dose may differ from the dose set by using TDM analysis software. In addition, since the recommended dose per body weight is a range and not a single value, setting the dose appropriate to target trough concentration is necessary.

It is well known that haloperidol is effective in the management of nausea and vomiting in cancer patients and that midazolam is used for inducing sedation in patients with delirium. Both the drugs are frequently used in a clinical setting, but there have been only few reports thus far on the concomitant administration of these 2 drugs. We report the case of a patient with massive ascites due to peritoneal carcinomatosis who had severe nausea and vomiting and went into a delirious state. This patient received a concomitant continuous infusion of haloperidol and midazolam for the management of these symptoms. Both haloperidol (up to 1.87mg/h) and midazolam (up to 1.87mg/h) were infused intravenously. For about 20 days, the nausea, vomiting and delirium were well under control without the development of any life threatening toxicities. Concomitant haloperidol and midazolam infusion was found to be a safe and effective therapy for the management of nausea and vomiting in the patient. Palliat Care Res 2009; 4(1): 312-316

Opioids are potent analgesics mostly used for severe cancer and chronic noncancer pain. However, their efficacy and safety in acute noncancer pain are debatable. We describe the case of an 82-year-old male with severe back pain due to bacteremic Staphylococcus aureus spondylitis and paravertebral abscess. Pain in such cases is usually controlled by non-steroidal anti-inflammatory drugs (NSAIDs). However, this patient was administered morphine (oral, then intravenous; up to 23 mg/day) because acetaminophen and NSAIDs did not ameliorate pain. Considerable pain relief was achieved without toxicity, and the dose of morphine was tapered through 35 days. No symptoms of addiction or withdrawal were observed during or after this 35-day period. Thus, morphine appears to be safe and effective in the management of severe, acute noncancer pain in patients with bacterial spondylitis. Palliat Care Res 2010; 5(2): 327-331

Purpose: We conducted a group seminar for lung cancer patients. The purpose of the group seminar was to eliminate the negative notions about opioids and to impart the right knowledge about these drugs. Further, we investigated the notions about opioids and the effectiveness of the group seminar. Methods: A pharmacist conducted a group seminar on opioids for lung cancer inpatients who agreed to participate in the group seminar. Moreover, we performed a questionnaire survey before and after the delivery of the group seminar. Results: Sixty patients answered the questionnaire. After completion of the group seminar, the understanding and knowledge about opioids increased, as indicated by the responses of the patients to all of the questions. Conclusion: Complete elimination of the negative notion about opioids could not be achieved through the group seminar. However, the group seminar was thought to be one of the useful methods of educating patients. If a patient resists treatment with opioids, control of pain may be delayed. This in turn would hamper improvement of the quality of life. Therefore, we consider that it is necessary that a patient has the right knowledge about opioids beforehand.

Clear cell carcinoma (CCC) of the ovary is known to show poorer sensitivity to chemotherapeutic agents and to be associated with a worse prognosis than the more common serous adenocarcinoma or endometrioid adenocarcinoma. To improve the survival of patients with ovarian CCC, the deeper understanding of the mechanism of CCC carcinogenesis as well as the efforts to develop novel treatment strategies in the setting of both front-line treatment and salvage treatment for recurrent disease are needed. In this presentation, we first summarize the mechanism responsible for carcinogenesis. Then, we highlight the promising therapeutic targets in ovarian CCC and provide information on the novel agents which inhibit these molecular targets. Moreover, we discuss on the cytotoxic anti-cancer agents that can be best combined with targeted agents in the treatment of ovarian CCC.

PREAVOID is pharmaceutical intervention that is utilized to illustrate pharmacists’ contributions to medical care. Currently, there is a great need for pharmacists to provide good medical services to inpatients; as a result, many pharmacists conduct pharmaceutical management in hospital wards. However, pharmacists who have limited experience in working in the ward do not know exactly what they should check with respect to pharmaceutical management. To resolve this problem, we determined 16 pharmaceutical-management items based on PREAVOID that was conducted at Nagara Medical Center. Moreover, we conducted a pre-questionnaire survey assessing whether pharmacists who had worked in the ward for fewer than 4 years attended to these 16 check items in their daily work prior to our introducing the list to them. The results indicated that pharmacists who had fewer than 2 years of experience working in wards attended to the 16 check items less than those who had more than 2 years of experience, and approximately half of the pharmacists had not received adequate guidance before beginning work at the ward. In addition, most pharmacists indicated that clear check points were useful for conducting pharmaceutical management and the 16 check items were useful for their daily work. These results indicate that the 16 check items are a useful educational tool for enabling pharmacists to conduct high quality pharmaceutical management from the initial stage and that using the 16 check items is superior to pharmacists only gaining this ability via prolonged experience working in the ward.

A 54-year-old man with unstable angina and Wolff-Parkinson-White (WPW) syndrome was admitted. Coronary angiography showed 90% stenosis of the left main trunk and 75% stenosis of the obtuse marginal branch. Coronary artery bypass grafting under cardioplegic arrest was done emergently. The left internal mammary artery graft was anastmosed to the left anterior descending artery, and a saphenous vein graft was used as a sequential bypass graft to the high lateral branch and obtuse marginal branch. Immediately after weaning from cardiopulmonary bypass, paroxysmal supraventricular tachycardia (PSVT) requiring electrical cardioversion was occurred, and catheter ablation was performed on the first postoperative day. There are controversus concerning the strategies of surgical treatment for unstable angina concomitant with WPW syndrome. Coronary bypass operation may trigger PSVT in patients with WPW syndrome. The optimal timing of perioperative catheter ablation needs further discussion.
