In the case of gastric cancers, it is essential to determine the extent and depth of the tumor accurately for deciding on courses of treatment. We have sometimes experienced the cases that pre-therapeutic diagnosis of those factors were difficult. In this report, we describe a case of gastric linitis plastica, which was diagnosed based on the ESD and additional surgical specimens. The patient was 60 years old man. A depressed lesion was pointed out at the greater curvature of middle gastric body. Biopsy revealed pooly differentiated and signet ring cell adenocarcinoma. Using magnification and EUS, this lesion was diagnosed as intramucosal cancer and 20mm in size. After informed consent, ESD was performed and the lesion was resected in en bloc fashion. However pathological examination showed incomplete resection of margin positive in endoscopic specimen and isolated cancer cell remained in the muscle layer in surgical resected specimen. Finally, this case was diagnosed of gastric linitis plastica based on the pathological examination.

An 18-year-old male who abused several over-the-counter (OTC) drugs, mainly diphenhydramine, was admitted to the emergency department. He presented with tachycardia, delirium, tremor, and tonic convulsions. He was treated with diazepam, tracheal intubation, and activated charcoal. His symptoms appeared to be caused by diphenhydramine poisoning. In addition, we suspected that the combined use of diphenhydramine, alcohol, and an anticholinergic agent exacerbated the poisoning symptoms. His symptoms improved with time and he was discharged on day 6.In recent years, the routes for obtaining drugs and information are becoming more diverse. While OTC drugs are often readily available, we need to be aware that certain types of medication can cause serious symptoms.

Cu/low-k配線パターンのラインエッジラフネス(LER)評価方法を確立するため,レジスト,low-k,Cu/low-kパターンをCD-SEMで観察し,典型的なラフネス形状を抽出するとともに,LER起因の電界集中をシミュレーションにより見積もった.low-k及びCu/low-kパターンにはくさび形のLERが観測されたが,このようなLERはくさびの先端部で,時間依存性絶縁破壊(TDDB)特性劣化につながる電界集中を引き起こすことがシミュレーションにより示された.また電界集中の予測には,low-kパターンのエッチング後及びCuのCMP後に,LERの大きさ(3sigma)とくさび形の開き角を評価することが効果的であると分かった.
