Purpose: We identified the risk factors for remnant gastric cancer (RGC) based on remnant gastric mucosal characteristics and gastritis morphology in patients undergoing distal gastrectomy. Materials and Methods: This multicenter retrospective study included 100 patients with RGC after distal gastrectomy and 550 patients without RGC treated between 2013 and 2020.Endoscopic findings, including anastomotic redness, red streaks, enlarged folds, bile reflux as anastomotic findings, as well as disappearance of the regular arrangement of collecting venules (RAC), atrophic gastritis, and intestinal metaplasia as background gastric mucosal findings, were evaluated. Disease risk score matching (1:1) was adjusted for baseline characteristics. Logistic regression analysis was used to develop a risk score model to stratify RGC risk into low, moderate, and high categories. Results: After matching, 96 patients with RGC and 96 controls were analyzed. Anastomotic redness and red streaks, as well as the disappearance of RAC and atrophic gastritis, were significantly more frequent in the RGC group than in the control group, whereas enlarged folds and bile reflux showed no significant differences. Risk scores were assigned as follows:anastomotic redness, 2; red streaks, 3; disappearance of RAC, 7; and atrophic gastritis, 3. The total score stratified patients into high (≥15), moderate (7–14), and low risk (≤6). The positive and negative predictive values were 67.7% and 83.3%, respectively. Conclusions The endoscopic findings of anastomotic redness, red streaks, RAC disappearance, and atrophic gastritis were significantly associated with RGC development.The proposed risk-scoring model could serve as a stratification tool for RGC surveillance.

In Chronic cases of hemiplegia following cerebrovascular disorders, it has been commonly accepted that the skin temperature on the affected side is lower than that of the normal side.
However, there has been no report regarding changes of the skin temperture before and after a long-term rehabilitation.
In this study, skin temperature of the lower legs before and after a long-term rehabilitation was measured in 21 normal subjects and in 53 patients with hemiplegia lasting over a month from the onset of cerebrovascular disorders.
Although the skin temperture of the lower legs in 21 normal subjects showed almost no difference between the two legs, that of hemiplegic patients was lower on the affected side and it was extremely lower in patinets with moderate or advanced hemiplegia. In the hemiplegic patients with moderate or advanced muscle atrophy on the affected side, the drop of skin temperature on that side was larger than that of the patients with no or sligit muscle atrophy.
In the hemiplegic patients who showed a moderate or marked improvement of the walking ability after rehabilitatlon, the skin temperature on both legs had been considerably lower than that of the patients who showed no or slight improvement of the walking ability before the rehabilitation. However it increased remarkably after the rehabilitation so that there was no significant differences of the skin temperature between the two groups of patients.
