A 62-year-old man visited his primary care physician with the complaints of loss appetite and fatigue. He was admitted to our hospital based on a diagnosis acute kidney injury, Fanconi syndrome as indicated by hypokalemia, hypouricemia, hypophosphatemia, elevated glucose levels in urine, aminoaciduria. had been taking multiple supplements, including Red Yeast Rice Cholesterol Help®, for one half years. After admission, all supplements were stopped. Blood samples collected; however, negative...

85歳,男性.前立腺癌に対して抗アンドロゲン剤であるアパルタミドの内服を開始した.内服開始50日後に全身に皮疹が出現し,38℃台の発熱を認め皮膚科に紹介となった.アパルタミドによる中毒性表皮壊死症(toxic epidermal necrolysis: TEN)の診断で入院となり,ステロイド内服での治療を開始した.第27病日ごろより全身の淡いびまん性紅斑の新生を認め,血漿交換療法を計8回施行したところ,皮膚病変の緩やかな改善を認めた.TENは多くの場合薬剤が原因とされ,非常に死亡率の高い疾患である.血漿交換療法については,病状の進行を抑制することから有用とする報告が多くみられる.また,アパルタミドは臨床試験において,とくに日本人に高頻度に皮疹を合併することが知られている.アパルタミドの普及により,本例のような重症型薬疹も今後増加する可能性がある.病因の解明のため,今後の研究が望まれる.

末期腎不全で維持血液透析中の55歳男性が.左重症下肢虚血に対して繰り返し血管内治療を施行されていた.左足の感染の増悪で入院となり,抗生剤加療が開始された.左第3から5趾の重症下肢虚血に対して第7病日よりACE阻害薬を中止し第10病日より吸着式潰瘍治療法レオカーナ®を施行した.開始後6分で血圧低下を認めレオカーナ®中止と生理食塩水の補液を行ったがショック状態が持続した.ノルアドレナリン投与にてショック状態から離脱したが10時間後まで低血圧が持続した.レオカーナ®とACE阻害薬の併用はブラジキニンによるショック状態が出現する懸念があり禁忌である.メーカーから1か月前からの休薬期間が推奨されているものの明確な中止基準が存在しない.本症例ではレオカーナ®施行3日前よりACE阻害薬を中止としたがショック状態が出現し遷延した.レオカーナ®を施行する際のACE阻害薬の中止期間には特段の注意が必要であり報告する.

The molar volume, optical basicity, X-ray fluorescence spectra of Al Kα and photoelectron O1s, B1s Al2p core electrons were measured for alkaline earth aluminoborate (CaBAl BaBAl) glasses as a function ratio MO/(MO+B2O3)=X (M=Ca Ba). Inflections discontinuities in the property vs. X curves, instance, compositions containing 20mol% Al2O3 discussed terms formation [BO4]- [AlO4]- units partition MO to B2O3 Al2O3. Each these anomalies was attributed to: increase electron density on bridging...

We investigate shrinkage priors on power spectral densities for complex-valued circular-symmetric autoregressive processes. construct predictive densities, which asymptotically dominate (i) the Bayesian density based Jeffreys prior and (ii) estimative with maximum likelihood estimator, where Kullback-Leibler divergence from true to a is adopted as risk. Furthermore, we propose general constructions of objective Kähler parameter spaces by utilizing positive continuous eigenfunction...

We investigated Bayesian predictive distributions for Wishart under Kullback–Leibler divergence. conditional reducibility family enables us to decompose risk a distribution. considered recently introduced class prior distributions, which called enriched standard conjugate and compared based on these distributions. Furthermore, we studied performance reference showed that there exists...
