EUS-EG might be helpful for the differential diagnosis of gastric SMT, especially to differentiate GIST from other SMT.

It has become clear that Bartonella henselae is a common cause of cat scratch disease (CSD). The indirect fluorescence antibody (IFA) test for detection of IgG and IgM antibodies to B. henselae concerning CSD showed that 5 (50%) of 10 patients with CSD had a serum IgG antibody titer of 1:128 or more and that 2 (20%) patients had a serum IgM antibody titer of 1:20 or more. One of 7 asymptomatic members of patients' families (14%) had IgG antibody to B. henselae at a titer of 1:256. IgM antibody to B. henselae was not detected in sera from the patients' families. Both IgG and IgM antibodies to B. henselae were not detected in sera from the healthy control group. These data suggest that B. henselae may be a cause of CSD in Japan.

Gastroenterologist-guided propofol sedation during gastric ESD may be acceptable even in the elderly with ASA classification I/II under careful monitoring of vital signs and oxygen saturation.

Summary:The usefulness of magnifying endoscopy was assessed by examining the extent to which a magnifying endoscope can provide images of pits and by analyzing the consistency of the pit patterns visualized by magnifying endoscopy with the pit patterns visible under a stereomicroscope. Study materials consisted of 83 cases of tumorous colorectal lesions. Under a magnifying endoscope, pits were visible across the entire surface of the lesion in 46 (55.4%) of the 83 cases. The pit pattern visualized by magnifying endoscope in 32 (69.6%) of the 46 cases was identical to the pattern observed under a stereomicroscope. Of various pit patterns, type Ills (tubular, round pit that is smaller than normal pit), type Ills (tubular, round pit that is larger than normal pit) and type IV (dendritic, gyrus-like type pit) were relatively well visualized under a magnifying endoscope. It was difficult to obtain images of type V (irregular or amorphous pit) with a magnifying endoscope. It seems therefore easy to distinguish tumors from non-tumorous lesions using a magnifying endoscope. This imaging technique may provide information more useful for the diagnosing tumorous colorectal lesions and selecting therapeutic strategy, if staining methods and mucusremoving methods are improved.
