A case of Cushing's syndrome due to adrenal black adenoma

Functional black adenoma of the adrenal gland is rare, and there are few reports. We report a case of functional black adenoma of the adrenal gland associated with Cushing's syndrome. The case was in a 59-year-old female, whose chief complaints were weight gain and general fatigue for 7 years. Clinical and laboratory findings were characteristic to those of Cushing's syndrome. With computed tomography and ultrasonography, a round tumor about 18 x 12 mm was detected at the left suprarenal region. Left adrenalectomy was done and a black tumor, 5.0 g in weight, was obtained. Most of the adenoma cells contained numerous pigmented granules which were considered as lipofuscin. The patient is alive without any symptoms of Cushing's syndrome 8 months after the operation. The Japanese literature of the functional black adenoma was also reviewed

Fine particles of platinum and ruthenium were loaded on tungsten trioxide powder by various methods such as photoprecipitation, impregnation and impregnation followed by hydrogen reduction methods. Photocatalytic performance of the specimens was examined for acetaldehyde decomposition and water splitting. Pt loaded WO3 via photoprecipitation method showed excellent performance for acetaldehyde decomposition under irradiation of black light. Oxygen was evoluved from water with 295μmol/24h via Pt loaded WO3 sample made by impregnation followed by hydrogen reduction method

Spontaneous peripelvic extravasation: reports of two cases

Spontaneous peripelvic extravasation must be distinguished from spontaneous rupture of the renal pelvis in urological emergency. The literatures revealed 42 cases of peripelvic extravasation and 35 cases of rupture of the renal pelvis in Japan. Most of them were caused by urolithiasis and malignant tumors. We report 2 cases of spontaneous peripelvic extravasation caused by urolithiasis, which were successfully treated conservatively

わが国におけるB 型肝炎ウイルス(HBV)母子感染予防法として厚生省方式(HB ワクチン生後二ヶ月開始,HBIG2回投与)が広く実施されてきた.同時期に開発された千葉大方式(HB ワクチン生後24時間内開始,HBIG1回投与)の多施設共同臨床治験により,同方式と厚生省方式間で児の能動免疫獲得率・キャリア化率,有害事象発生率に関して有意差が無く,省力化・安全性・経済性の観点から千葉大方式の優位性が報告されている.今回,HBV 母子感染予防対策を児のHBV キャリア化阻止と対策漏れにエンドポイントを絞り,千葉大方式を更に簡略化し,全ての処置を生後1 ヶ月健診時に完了する獨協医大方式(HB ワクチン生後24時間以内開始,HBIG1回投与)の臨床治験を日本および中国大連市において実施した.両方式群間で,児の能動免疫獲得率,生後6 ヶ月時獲得HBs 抗体価,キャリア化率,有害事象発生率の全てにおいて有意差を認めず,一方,省力化・経済性と対策漏れに関しては獨協医大方式の優位性が判明した.獨協医大方式はその経済性,簡便性より,わが国はもとよりHBV 侵淫地域であるアフリカ,東南アジア諸国等においても積極的採用が期待され得る選択肢である
