Abstract Background Under-recognition of depression is common in many countries. Education medical staff, focusing on their attitudes towards depression, may be necessary to change behavior and enhance recognition depression. Several studies have previously reported toward among general physicians. However, little known about non-psychiatric doctors Japan. In the present study, we surveyed doctors’ attitude Methods The inclusion criteria participants study were as follows: 1) Japanese 2)...

Hemodialysis leukopenia was studied using various dialyzers and membranes. We found that with cellulosic membranes caused marked leukopenia, but in recently developed non membranes, its occurrence significantly less. Additionally, our results showed a newly cellulose acetate membrane to correlate well the regarding spite of it being derivative cellulose.The extent white blood cell decrease seemed inversely an increase ultrafiltration rate per area dialyzer.The relationship between hypoxemia...

透析患者に対し,治療を円滑に行うために必要なシャントの日常管理のうちでも,特に狭窄の診断は極めて重要である.シャント音の聴診はシャント狭窄を簡便に診断する方法として日常的に用いられている.臨床経験上,狭窄の進行に伴って高調なシャント音が聴診されることが知られているが,この診断には客観的な基準がなく,聴診者の主観に頼っているのが現状である.そこでわれわれはこの診断基準の確立に向けた基礎的研究として,シャント音を周波数解析し,狭窄度と周波数スペクトルの関係について解明することを試みた.方法としては,まず患者のシャント(動静脈吻合)の吻合部より中枢部に向けて3~6箇所の部位で複数のシャント音を記録し,短時間フーリエ変換により周波数スペクトルを算出した.次にシャント狭窄度とシャント音の周波数スペクトルとの関係をスペクトルの平均値の有意差により解析した.その結果,吻合部(シャント狭窄部より上流域)および狭窄部上では,狭窄の進行に伴い高周波数帯域のスペクトルの割合が有意に大きいことが確認された.一方,中央部(狭窄部より下流域)では基本的に狭窄度と周波数帯域との間に有意差は確認できなかったが,...

We describe a 43-year-old male patient with congenital antithrombin III deficiency requiring hemodialysis due to extension of venous thrombus from recurrent deep vein thrombosis. During dialysis adequate heparinization, the often revealed clot formation in extracorporeal circuit resulting unexpected discontinuation dialysis. When either combination concentrate + heparin or newly developed synthetic preparation, MD805, was administered during dialysis, he could be uneventfully dialyzed two regimens.

在宅血液透析における患者による自己穿刺の容易性を高めるため,自己穿刺補助具を開発した.補助具のプロトタイプは三次元立体造形技術により,アクリロニトリル・ブタジエン・スチレン共重合体(ABS)樹脂を用いて製造された.当該補助具は,台座部,延設部,アーム部,突起部,および血管を圧迫固定するための弾性的な付勢手段としてのトーションバネから主に構成された.穿刺する際,アーム部をトーションバネの付勢力に抗して揺動させて腕を挿通し,突起部にて血管を押圧する.さらに,その押圧状態から患者の腕を穿刺方向にわずかにずらすことにより,血管を伸展固定できるように設計された.
