[Successful treatment of the diverticular lesion of the colon via EMR with over-the-scope clip (OTSC):a case report].

A 65-year-old woman presented with a flat elevated lesion of about 1cm in the cecal diverticulum during a lower gastrointestinal endoscopy that was performed previously by another physician during a medical checkup. The patient was referred to our department for resection. Considering the risk of perforation owing to the diverticular lesion, positive nonlifting sign, and Group 5 diagnosis on the previous biopsy, EMR with over-the-scope clip (OTSC) (EMRO) was selected, and complete resection was achieved without complications.

Diagnostic Strategy of Early Stage Pancreatic Cancer via Clinical Predictor Assessment: Clinical Indicators, Risk Factors and Imaging Findings.

Early detection of pancreatic ductal adenocarcinoma (PDAC) in the general population is difficult due to unknown clinical characteristics. This study was conducted to clarify the factors associated with early stage PDAC. Well-known symptoms and factors associated with PDAC were classified into clinical indicators, risk factors, and imaging findings concomitant with early stage PDAC.

Consumption of seafood, serum liver enzymes, and blood levels of PFOS and PFOA in the Japanese population.

Objective: Perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) have been shown to accumulate in the human body. The purpose of the present study was to examine the factors associated with the blood levels of PFOS and PFOA.

Methods: A cross-sectional study was performed on 307 men and 301 women (aged 16-76 years) living in 15 prefectures in Japan.

Association between blood levels of PCDDs/PCDFs/dioxin-like PCBs and history of allergic and other diseases in the Japanese population.

Background: Previous studies reported that exposure to dioxins was associated with an increased risk of various diseases in general populations.

Objectives: The aim of this study was to examine the association between levels of dioxins in blood and allergic and other diseases.

Methods: We conducted a cross-sectional study on 1,063 men and 1,201 women (aged 15-76 years), who were living throughout Japan and not occupationally exposed to dioxins, during 2002-2010.

[A case of pulmonary Mycobacterium gordonae infection progressed for no therapy].

A 68-year-old woman, who had been healthy until this event, presented with a complaint of productive cough since 2000. She went to a neighboring hospital because of bloody sputum in October 2001. Although chest radiograph showed abnormal findings then, she received only an expectorant and cough remedy.

Fatal cytomegalovirus-associated adrenal insufficiency in an AIDS patient receiving corticosteroid therapy.

A 35-year-old homosexual man, who had already received sulfamethoxazole/trimethoprim and steroid therapy because of human immunodeficiency virus (HIV)-related Pneumocystis jiroveci pneumonia, was referred to our hospital. He was also diagnosed as having cytomegalovirus (CMV) co-infection, and started receiving intravenous gancyclovir for CMV infection on the 2nd day of admission into our hospital. He had to continue the steroid therapy because his respiratory condition did not improve.

[A case of AIDS-associated Haemophilus influenzae pneumonia with diffuse reticulonodular shadows].

A 32-year-old male was admitted to our hospital complaining of fever and dyspnea on effort. Laboratory data on admission indicated leukocytosis and elevation of C-reactive protein. A chest radiograph showed diffuse reticulonodular shadows in both lower lung fields, and a chest computed tomography showed centrilobular reticulonodular opacity.

AIDS-related Pneumocystis carinii pneumonia with disappearance of cystic lesions after treatment.

A 21-year-old hemophiliac with human immunodeficiency virus (HIV) infection was admitted to our hospital because of bilateral pneumothoraces associated with Pneumocysis carinii pneumonia (PCP). He underwent chest tube drainages and intravenous pentamidine therapy, resulting in clinical improvement. Two months after treatment for PCP, cystic lesions that had existed before treatment disappeared on chest computed tomography.
