RESUMEN

Objective: Associations between vascular calcification and osteoporosis are well documented, yet effects of lifestyle on atherosclerosis and osteoporosis remain unclear. This study evaluated the relationship between atherosclerosis and osteoporosis of people with different lifestyles living on Uku Island in Japan (rice consumption and fishing lifestyle) and in Ulaanbaatar in Mongolia (meat consumption and nomadic lifestyle), and investigated the differences of lifestyles on atherosclerosis and osteoporosis. Methods: Participants were women aged over 50 years who had undergone a previous medical examination for atherosclerosis and osteoporosis (Uku Island, 104, Ulaanbaatar, 71). Lifestyle habits were obtained by questionnaire. Bone mineral density of the right calcaneus was measured using quantitative ultrasound. Brachial-ankle pulse wave velocity was measured as an index of atherosclerosis. Results: There were no significant differences in bone mineral density and brachial-ankle pulse wave velocity between the two groups, even though meat and dairy intake, number of meals skipped, and number of children were significantly greater in participants from Ulaanbaatar compared with Uku Island. Brachial-ankle pulse wave velocity showed significant positive correlations with age, systolic and diastolic blood pressures, and body mass index and a significant negative correlation with bone mineral density for both groups. With step-wise multiple regression analysis, brachial-ankle pulse wave velocity significantly correlated with age and bone mineral density for both populations. Systolic blood pressure significantly correlated with brachial-ankle pulse wave velocity for the Ulaanbaatar group. Conclusions: Despite significant lifestyle differences, similar relationships between atherosclerosis and osteoporosis were observed in women from Uku Island and Ulaanbaatar. Hypertension was a significant contributing factor for atherosclerosis for the Ulaanbaatar group.

RESUMEN

We encountered cases of unresectable gastric cancer in which patients had difficulty with ingestion because of pyloric stenosis and diffuse invasion. We examined the improvement in the quality of life(QOL)of patients and the effect and usefulness of S-1 treatment in such cases. The median survival time(MST; 310 days)of patients who received S-1 as primary treatment was significantly longer than that(105 days)of patients who did not receive S-1 treatment(p=0.0001). Of the 25 patients who underwent gastrojejunostomy, S-1 was administered to 10 patients(MST: 384 days). The MST of patients who received drugs other than S-1 was 121 days. Thus, the MST of patients who did receive S-1 was significantly longer than that of patients who did not receive S-1. In univariate analysis, oral ingestion, performance status(PS), best supportive care(BSC), and S-1 administration were prognostic factors. Of these factors, oral ingestion(p=0.0278, hazard ratio[HR]: 2.992)and S- 1 administration(p=0.0002, HR: 14.956)were prognostic factors in multivariate analysis. Gastrojejunostomy is desirable for the treatment of cases of unresectable gastric cancer with poor ingestion. In addition, the use of postoperative chemotherapy with S-1 alone or with S-1 as combination therapy may help improve prognosis.

RESUMEN

As the impact of visceral fat volume on surgical outcomes in colorectal resection had not previously been assessed, this study was designed to compare the surgical outcomes of colorectal resection in obese and nonobese patients. From 2004 to 2007, 79 operative patients with colorectal cancer were examined. Of these, 25 were obese (i.e., greater than 100 cm2 visceral fat volume), and 54 were nonobese. Mean operating time was significantly longer in obese than in nonobese patients (P < 0.01). Mean blood loss was significantly greater in obese than in nonobese patients (P < 0.01). Mean blood loss/h was significantly greater in obese than nonobese patients (P < 0.01). Surgical site infection was more common in obese than in nonobese patients, but this difference was not statistically significant. In conclusion, this study suggested that a visceral fat volume of greater than 100 cm2 may be one of the risk factors in colorectal resection.

RESUMEN

A 77-year-old man was admitted to our hospital. He had first noticed a cough, sputum production, and low-grade fever during the summer of 1988. He was diagnosed as having summer-type hypersensitivity pneumonitis (HP) in 1989 on the basis of positive findings of anti-Trichosporon antibodies in the serum and bronchoalveolar lavage (BAL) fluid and and in environmental provocation tests. Thereafter, he presented with re-exacerbation of his disease in summer every year. In 1995, he retired from his work at a moldy hotel and moved to another house to avoid the causative antigen completely. There was no recurrence for the following 5 years. He suffered from cough, sputum production, and dyspnea 4 months after returning to his previous moldy house in October, 2000. A chest CT scan showed peribronchial and subpleural honeycombing, ground glass opacities, and traction bronchiectasis. BAL demonstrated that the lymphocyte count had changed from 78.9% to 42.9% and the CD4/CD8 ratio from 0.39 to 4.07 in 12 years. Antigen avoidance and steroid therapy have improved his condition. However, he stayed repeatedly in his moldy house, and finally died from acute exacerbation in March, 2002. Postmortem examination demonstrated diffuse alveolar damage (DAD) superimposed on honeycombing in the lungs.
