Postoperative nausea and vomiting (PONV) are common and unpleasant postoperative complications. Although guidelines recommend preventative measures according to PONV risk, anesthesiologists do not always follow the guidelines. In this study, we investigated whether the pharmacists’ proposal of a PONV prevention method to anesthesiologists in accordance with the guidelines affected the decision-making of anesthesiologists and subsequent PONV development. Two hundred and five patients who underwent gynecological surgery at Keiyu Hospital were included in this study, and the number of preventative measures selected by an anesthesiologist and frequency of PONV complications before and after the pharmacists’ intervention were determined. After the intervention, the number of preventative measures implemented by the anesthesiologist increased in the PONV moderate- and high-risk groups (P < 0.01) and incidence of PONV in patients decreased [odds ratio 0.362 (95% confidence interval 0.174 - 0.726) (P < 0.01)]. It is the intention of anesthesiologists for pharmacists to evaluate PONV risk and propose preventative measures that comply with guidelines to anesthesiologists. The results of this study show that the proposal of pharmacists on PONV prophylaxis affects anesthesiologists’ decision-making and is effective in preventing PONV.

Objective: Celecoxib has been reported to enhance the action of warfarin by inhibiting CYP2C9, its major hepatic drug-metabolizing enzyme, but sufficient information about the mechanism has not been obtained, especially in Japan.Methods: A study was conducted to investigate the prothrombin time international normalized ratio (PT-INR) and the warfarin sensitivity index (WSI) before and after concurrent administration of celecoxib, as well as the Drug Interaction Probability Scale (DIPS) scores to determine causality with drug interactions, in patients commencing concurrent therapy with celecoxib and warfarin at Kanagawa Prefectural Keiyukai Keiyu Hospital during the 4-year period from October 2011 to September 2015.Results: Analysis of 18 patients showed that the PT-INR increased significantly from 1.53±0.43 before concurrent therapy to 2.18±1.01 after concurrent therapy (p=0.0101).  The WSI also increased significantly from 0.76±0.50 before concurrent therapy to 1.01±0.65 after concurrent therapy (p=0.0044).  According to the DIPS scores, the causal relation was not rated as “Highly Probable” in any of the patients, while it was considered to be “Probable” in 3 patients, “Possible” in 10 patients, and “Doubtful” in 5 patients.Conclusion: The findings of this study suggested that when celecoxib treatment is initiated in patients who are already taking warfarin, attention must be paid to changes of coagulation profile, especially in elderly patients.

We established dose estimation formulae for renal-excretion drugs using the glomerular filtration rate (GFR), tubular secretion clearance (Sc), and unbound fraction of drug in plasma (fp) as a renal function index of physiological development in neonates and infants not more than 2 years of age. A dose ratio of (D_C/D_A)=clearance ratio of (CL_C/CL_A)≅(fp_C·GFR_C)/(fp_A·GFR_A) for neonates and infants/adults was applied to drugs with fp·GFR>Sc, while D_C/D_A=CL_C/CL_A≅(β·BSA_C+fp_C·GFR_C)/(β·BSA_A+fp_A·GFR_A) was applied to drugs with Sc>fp·GFR using the coefficient of each drug (β) and body surface area (BSA). Validity of the estimation formulae was investigated in drugs with fp·GFR>Sc such as vancomycin (VCM), arbekacin (ABK), fosfomycin (FOM) and norfloxacin (NFLX), and in drugs with Sc>fp·GFR such as digoxin (DGX) and amoxicillin (AMPC). First, we compared the clearance ratio (CL_C/ CL_A) of VCM, ABK, and DGX estimated by our method with those calculated using the Japanese population clear- ance values and those estimated allometrically (BSA_C/BSA_A). Next, we compared the established doses of all drugs investigated with the doses for neonates and infants calculated from the conventional dose estimation methods for children and our estimation formulae, and evaluated our method. As a result, favorable consistency was observed in the CL ratio for all drugs, and the doses of VCM, FOM, NFLX and AMPC calculated from our estimation formulae approximated the established doses. In conclusion, the validity of the dose estimation method using pharmacokinetic factors related to physiological development (i.e., GFR, fp, Sc) for renal-excretion drugs in neonates and infants was demonstrated.<br>

Conventional dose estimation methods do not consider drug factors and do not allow for various pharmacokinetic factors associated with the growth of children. I have therefore established a new method based on drug elimination processes and physiological and biochemical developmental factors in order to more appropriately estimate pediatric doses (the ePPBD method). Renal excretion or hepatic metabolic clearance was calculated for each age based on physiological and biochemical developmental factors, such as the unbound fraction of the drug in plasma, glomerular filtration rate, tubular secretion, liver volume, and CYP enzyme activity. Then the pediatric dose was estimated by multiplying the adult dose by the pediatric/adult ratio of renal excretion or hepatic metabolic clearance. Accuracy of the ePPBD method was compared with conventional methods, using the population mean clearance and the doses listed in package inserts and text books as the standards to quantitate its validity. In brief, accuracy was evaluated by classifying children into the following age groups: 1) neonates in consideration of the post-conceptional age (PCA), 2) infants up to 2 years old, and 3) children over 2 years old for drugs with renal excretion, or 4) children of all ages for drugs with hepatic metabolism. The accuracy of the ePPBD method was superior to that of conventional methods both for drugs with renal excretion and those with hepatic metabolism, and therefore it should be useful for pediatric patients in whom physiological function changes remarkably as they age.

Morphologic characteristics of most of known oncogenic viruses, some of which were investigated by us, were described in relation to their oncogenicity and their localizations in tumor tissues.Oncogenic viruses were classified into six groups: type A, B, C, D, E and F. Viruses pertaining to type A were presumably not mature virus particles. Some of them could, however, be immature form or incomplete form of oncogenic virus particles. Viruses belonging to type B, C, D, E, and F were represented by mammary tumor virus of mice, leukemia viruses of mice and chickens, polyoma virus, Shope fibroma virus and Lucké renal adenocarcinoma virus, respectively. They were different in size and shape, and in the mode of development.It was presumed that type B and C viruses were members of the Myxovisus group and type D viruses belonged to Adenovirus and the Papova virus group. It was also believed that type E and F viruses had in general the feature of the Pox virus group and Herpes virus group, respectively.

Spontaneous mammary carcinoma of AKR mice and Xray-induced mammary carcinoma of C58 mice, both known as low-cancer strains, were investigated by electron microscopy.In AKR mammary carcinoma, intracytoplasmic type A and extracellular type B particles were present. In C58 mammary carcinoma, extracellular type C particles were observed. In both tumors, mature virus particles, i.e. type B and type C particles, were formed by the process of budding of cytoplasmic membrane of carcinoma cells and present in the lumina of the milk ducts. Aberrant form of type C particles, which contained a filamentous structure instead of a nucleoid was also seen in C58 mammary carcinoma.In serial in vivo transplantation of those carcinoma cells to the same strain mice, these virus particles were always present and formed from carcinoma cells, although the number of virus particles reduced almost successively with transplantations in AKR mammary carcinoma.In tissue culture of C58 mammary carcinoma cells, type C particles similar to those in the original tumor were observed extracellularly. On the contraty to the presence of type B particles in the original AKR mammary tumor, however, two tissue culture strains derived from in vivo transplanted AKR carcinoma cells contained type C particles. These type C particles were conceivable to be the leukemia virus that naturally harbored in AKR mice and happened to have been tranferred to the tissue culture probably through its latent infection in carcinoma cells.
