Recently, the relevance of Helicobacter pyroli (H. pylori) infection to atrophic gastritis and gastric cancer in has been elucidated. Therefore, to diagnose H. pylori infection is important for suspecting the existence of those diseases of the stomach. We investigated the relationships of the H. pylori IgG antibody to H. pylori infection, atrophic gastritisor various stomach lesions to understand the significance and usefulness of evaluating the antibody level in the annual multiphasic health check-up participants. The subjects in this study were 148 people (male: 93, female: 55, average age: 56.4) in Toride city, which is located in the suburb of Tokyo. They had visited our hospital for medical checkups. Eighty-seven subjects underwent upper gastric endoscopy and 55 (63%) tested positive for H. pylori IgG antibody and H. pylori infection was confirmed in 41 (75%). Although 32 subjects tested negative for the antibody, 8 cases (25%) was diagnosed with H. pylori infection. The frequencies of positive antibody in atrophic gastritis, erosion and ulcer, fundic gland polyp, hyperplastic foveolar polyp, adenoma and malignancy were 17%, 70%, 61%, 77%, 31%, 62%, 0% and 100%, respectively. On the other hand of 80 subjects were who underwent barium X-ray examination, 44 tested positive for the antibody (55%). The frequency of positive antibody in no lesion, depressed lesion, elevated lesion and malignant lesion were 61%, 59%, 36% and 100%, respectively. Taken together, H. pylori antibody was a good marker for H. pylori infection and the positive antibody indicated high frequencies of atrophic gastritis and malignancy. Therefore, advices to have participants who have a positive antibody should be strongly an endscopic examination stomach lesions.

Purpose: We examined the safety and efficacy of cataract surgery and postoperative management in our hospital and at the homes of the patients who live on medically underserved remote.
Patients and methods: A total of 27 patients (54 eyes), who were followed in our hospital or at their homes were enrolled in this study. Cataract surgery was performed on them between January 2009 and January 2010 and we could follow up six months postoperatively. We divided these patients into two groups:group I (GI) consisted of 13 patients who could come to our hospital regularly during both preoperative and postoperative periods, and group II (GII) consisted of 14 patients who could not come to our hospital regularly during either preoperative or postoperative periods. Cataract surgeries were performed on all the patients in GI and GII in our hospital. The patients in GI were hospitalized for three days and those in GII were for seven days. After cataract surgery, the patients in GI had their eyes checked regularly in our hospital and those in GII were in their homes where the doctor visited. Postoperative ophthalmic clinical tests were conducted to examine visual acuity, intraocular pressure and fundus.
Results: GI comprised three males and 10 females. Their age averaged 79.3. GII comprised four males and 10 females. Their age averaged 82.6. Preoperative ophthalmic examinations found that preoperative average visual acuity (LogMAR and decimal visual acuity in parentheses) and spherical equivalent in GI and GII were 0.69 (0.41), 0.80 (0.33) and -0.43 dioptors, -0.42 dioptors respectively, showing no significant differences between the two groups. Postoperative ophthalmic examinations found that, best corrected visual acuity (LogMAR) was significantly increased to 0.36 (0.66) and 0.44 (0.53) in GI and GII respectively, showing no significant differences either.
Conclusions: We concluded that we could get safe and efficient cataract surgery and postoperative management combined with prolonged hospitalization and house calls on the patients who live in the isolated islands.

Methods: Nineteen volunteers (16 men, three women) lifted a 60-kg doll from a seated position to a standing position. The first transfer was performed without the HAL for Care Support, and the second was performed with the HAL for Care Support assistive robot. We evaluated transfer performance, the visual analog scale (VAS) score for lumbar fatigue, and electromyogram analyses of the trunk and hip. Results: Four participants (two men, two women) succeeded with the HAL for Care Support even though they were unable to perform the task without it. The mean lumbar fatigue VAS score for all participants without the HAL for Care Support was 62 mm, while that with it was 43 mm. With lumbar assistance from the HAL for Care Support, subjective lumbar fatigue during the transfer decreased significantly. A power analysis indicated adequate statistical power to detect a difference in the VAS score for lumbar fatigue (0.99). The activity of the left gluteus maximus alone increased significantly during transfers with the HAL for Care Support. No adverse events occurred during use of the HAL for Care Support for transfers. Conclusions The HAL for Care Support was able to reduce lumbar load in a simulated patient transfer.
