A 60-year-old man, who had undergone mitral valve repair with quadrangular resection of the posterior mitral leaflet and ring annuloplasty with a Cosgrove-Edwards ring, developed severe mechanical hemolytic anemia. Doppler echocardiography showed only mild residual mitral regurgitation, but turbulent jet was directed toward the annuloplasty ring. Because of unremitting hemolysis requiring multiple transfusions and the occurrence of renal dysfunction, he underwent replacement of the mitral valve with a St. Jude Medical valve. Inspection of the annuloplasty ring at operation showed no evidence of dehiscence, but the area of the annuloplasty ring adjacent to the posteromedial commissure showed no endothelization. After the reoperation, the hemolysis and general condition immediately improved. This experience made us realize the possibility that a high-velocity regurgitant jet toward the cloth-covered annuloplasty ring, even if it mild, can cause severe hemolysis.

With an increasing number of patients suffering from chronic renal failure, the question of how to prolong the period before starting hemodialysis therapy has been attracting great attention. Kremezin^® and Daio-Kanzo-To, which have been reported to produce good clinical results, were administered to two patients with chronic renal failure in the preservation phase. When the treatment started, renal function tended to deteriorate, and hemodialysis had to be introduced in both patients. We investigated possible causes of this deterioration, and the effect of the combined use of Kremezin^® and Daio-kanzo-To the renal function could not be denied. This combination therapy needs to be studied very carefully.

It is suggested that in the use of tacrolimus for treatment of ulcerative colitis, it is important to achieve and maintain a high trough level as soon as possible. We examined two cases, with a starting initial dose higher than that recommended in the package insert, and adjusted the dose by daily therapeutic drug monitoring. Improvement of symptoms was observed by maintaining a high trough level of 10 to 15 ng/mL in these 2 cases. This improvement was observed from 9 days after achieving the high trough level, and it took the same number of days as stated in the mode of administration in the package insert.

Methods: The study participants were 249 patients who underwent intradiscal condoliase injection for LDH at nine participating institutions, including 241 patients with initial LDH (group C) and eight with recurrent LDH (group R). Patient characteristics including age, sex, body mass index, disease duration, intervertebral LDH level, smoking history, and diabetes history were evaluated. Low back pain/leg pain Numerical Rating Scale (NRS) scores and the Oswestry Disability Index (ODI) were used to evaluate clinical symptoms before treatment and at 6 months and 1 year after treatment. Results: Low back pain NRS scores (before treatment and at 6 months and 1 year after treatment, respectively) in group C (4.9 → 2.6 → 1.8) showed significant improvement until 1 year after treatment. Although a tendency for improvement was observed in group R (3.5 → 2.8 → 2.2), no significant difference was noted. Groups C (6.6 → 2.4 → 1.4) and R (7.0 → 3.1 → 3.2) showed significant improvement in the leg pain NRS scores after treatment. Group C (41.4 → 19.5 → 13.7) demonstrated significant improvement in the ODI up to 1 year after treatment; however, no significant difference was found in group R (35.7 → 31.7 → 26.4). Conclusions Although intradiscal condoliase injection is less effective for LDH recurrence than for initial cases, it is useful for improving leg pain and can be considered a minimally invasive and safe treatment method.

Patients with heart failure often have difficulty in stopping cardiotonic drugs as the disease stage progresses, and long-term hospitalization is a factor that significantly reduces quality of life. To solve this problem, in September 2017, our hospital started an initiative to support overnight stays at home by using a portable precision infusion pump and continuously injecting cardiotonic drugs with the approval of the hospital’s medical ethics committee. Since there are few case reports of similar efforts in Japan, here we describe the use of drugs and the content of the intervention by pharmacists. The drug is administered via a peripherally inserted central venous catheter using an ambulatory precision infusion pump. The pharmacist calculates the drug dose and flow rate required during the at-home period using spreadsheet software, and proposes a prescription to the doctor. In addition, if multiple cardiotonics and diuretics are administered, the presence or absence of compounding changes is confirmed, and the feasibility of mixing should be examined, and then prepared aseptically on a clean bench on the day of administration. We started to administer catecholamine while in the hospital on the day before the stay at home. Then we prepared the catecholamine in a portable precision infusion pump and administered it during stay at home. To date, we have supported 8 cases in stays at home without emergency hospitalization or sudden death due to exacerbation of heart failure.
