Background: Oral hypofunction (OHF) is related to occlusal status and bite force. It has specific symptoms and varying degrees of severity., Objectives: OHF was determined with five signs. The relationships between OHF and need for assistance in oral hygiene, moving, eating and occlusal status in older adults living in long-term care (LTC) were examined., Methods: A comprehensive clinical oral examination was conducted on 393 residents who lived in LTC in Helsinki, Finland. The five signs to determine OHF were mouth dryness, visible food residue on oral or denture surfaces, ability to keep the mouth open during examination, clearness of speech, and diet of pureed or soft food. Score points of 0-2 were given for each sign, and the sum was categorised as mild, moderate or severe OHF. Participants were divided into three groups accordingly, and occlusal status was determined based on contact units. In addition, nurses collected background information on number of medications and level of cognition. Need for assistance was based on oral hygiene, moving and eating., Results: Of participants (n = 319), 21% showed severe and 41% moderate OHF. Occlusal status differences between the OHF groups were significant. OHF severity associated linearly with increased severity of cognitive impairment and increased need for assistance in oral hygiene, eating and moving., Conclusions: OHF score based on the five signs can be used to determine OHF severity. OHF was common and associated with occlusal status, cognitive impairment and need for assistance in oral hygiene, moving and eating in older adults living in LTC., (© 2022 The Authors.

Background and Aim: Based on past diagnostic classifications of gastritis, the Kyoto classification of gastritis adopts simpler, more objective gastritis findings according to Helicobacter pylori infection status and evaluates the risk of gastric cancer. To clarify whether this score can predict future gastric cancer, we retrospectively examined risk scores obtained using the Kyoto classification of gastritis a few years prior to the diagnosis of early gastric cancer., Methods: We reviewed data from 50 individuals who had undergone upper gastrointestinal endoscopy 2-3 years prior to the diagnosis of early gastric cancer in our hospital. Two expert endoscopists evaluated and compared risk scores obtained using the Kyoto classification of gastritis between cancer and control groups., Results: With regard to the risk score obtained using the Kyoto classification of gastritis in all cases, atrophy, intestinal metaplasia, diffuse redness, and total score were significantly higher among gastric cancer cases. Among H. pylori -eradicated cases, atrophy score was higher in the gastric cancer group. Among patients for whom H. pylori had been eradicated for >3 years at first endoscopy, atrophy score was still higher in the gastric cancer group., Conclusion: This retrospective study suggested that the risk score obtained using the Kyoto classification of gastritis was useful for predicting the onset of gastric cancer. In particular, patients with a high atrophy score even after H. pylori eradication may be at high risk of developing gastric cancer., (© 2020 The Authors.

Purpose: Pancreatic/gastrointestinal tract neuroendocrine neoplasm (NEN) is divided into neuroendocrine tumor (NET) and neuroendocrine carcinoma (NEC) according to the grade of malignancy, and differences are seen in clinical prognosis. NET, and rectal NET in particular, is often treated endoscopically. Endoscopic mucosal resection (EMR) was previously the main intervention for rectal NET, but EMR with a ligation device (EMR-L) and endoscopic submucosal dissection (ESD) are now also used. However, complete resection with these therapies is not always achieved. The pocket creation method (PCM) is a safe ESD method for colon tumors that offers a high en bloc resection rate compared with conventional colonic ESD. We performed ESD using the PCM for rectal NET and evaluated the complete resection rate., Methods: We performed ESD using the PCM in 4 patients. This procedure was technically feasible in all patients., Results: Endoscopically, all cases were resected en bloc, and pathological complete resection was achieved in all cases. No complications such as perforation or delayed postoperative bleeding were encountered., Conclusions: PCM should be considered when treating NET of appropriate size.
