ABSTRACT: We investigated the clinical features of Bacteroides bacteremia for 5 years to determine the risk factors for mortality and to ascertain whether bacteremia due to Bacteroides spp. is associated with colorectal carcinoma.
This study comprised a review of all patients with Bacteroides bacteremia at a teaching hospital in Tokyo from April 2003 to March 2008. We also conducted a case-control study between Bacteroides bacteremia and bacteremia due to other pathogens.
During the study period, 25 cases of bacteremia were due to Bacteroides spp. Bacteroides bacteremia was associated with a high mortality rate (24%). Malignancy (76%) was the major comorbidity, followed by a history of surgery (40%). Colorectal carcinoma was the most frequent (n = 8, 32%) of the comorbid malignancies and was recognized as the primary infection site in six cases. Prevalence of colorectal carcinoma as comorbidity was significantly higher in Bacteroides bacteremia than in other bacteremia.
In the Bacteroides bacteremia cases of this study, colorectal carcinoma was the major comorbidity and primary infection site. Colorectal carcinoma screening in Bacteroides bacteremia patients is potentially an important diagnostic marker for the early detection of this infection in the future.

ABSTRACT: This study investigated the clinical characteristics of ciprofloxacin-resistant Proteus mirabilis isolates from urine samples associated with nosocomial infection or colonisation, and identified the risk-factors for ciprofloxacin resistance. Data for patients with ciprofloxacin-resistant P. mirabilis isolates (n=13) were compared with those for randomly selected patients with ciprofloxacin-susceptible P. mirabilis isolates (n=40) who were matched by temporal occurrence as control patients. The majority of ciprofloxacin-resistant P. mirabilis isolates were multiresistant, and ciprofloxacin resistance was associated significantly with previous use of fluoroquinolones and production of extended-spectrum beta-lactamases.

ABSTRACT: Nocardiosis is a serious infection with high mortality. We report a case of subcutaneous and neural lesions due to Nocardia farcinica infection after living-donor liver transplantation. The neural lesion was cured with antibiotics without drainage.

ABSTRACT: Clinical characteristics of elderly patients who had been admitted in Sawauchi Hospital for more than 100 days between 1988 and 1992, were analyzed. The average hospital stay of inpatients was 38.0 days, and the longest hospitalization was observed at ages between 76 and 85 year old. During 4 years, there were 74 patients who were admitted for more than 100 days. Thirty-seven cases had serious and complicated conditions, while the remaining 37 cases did not have clear-cut reasons for such a long hospitalization. The latter group was significantly older than the former, and included more females (p < 0.01, respectively; the care-forcussed group). Clinical characteristics of the care-forcussed group were degenerative bone/joint diseases with long-standing pain and uncertain complaints such as autonomic nerve dysfunction. These patients were often admitted to the hospital repeatedly, particularly in winter. Patients with multiple cerebral infarction or chronic respiratory disorders were mostly males (p < 0.01). It is important to examine the clinical course and severity of elderly patients who are in hospital for long periods, particularly from the viewpoint of differentiating quality of treatment and care.

ABSTRACT: To examine satisfaction with medical care in hospital for elderly people, a questionnaire was sent to 900 patients who discharged two geriatric hospitals recently. 598 answers were obtained (66%) and analyzed in relation to activity of daily living (ADL) and types of disorder. Although patients who were not satisfied with medical care were only 7 cases (1.2%), patients with lowered ADL and with cerebrovascular disease or bone/joint disease showed significantly negative response. These patients admitted immediately and stayed longer periods than other patients, but they wanted to stay more days in hospital. In addition, these patients judged attitude of medical staffs negatively in comparison with other ADL groups and other disorders. On the contrary, total dependency in daily living did not relate to dissatisfaction with medical care and attitude of medical staffs. Withholding of judgment was characteristic answer in this group. Satisfaction with keeping privacy in hospital decreased in parallel to decrease of ADL. These results suggest that dissatisfaction with medical care is centered on patients with compromised independence. This must be considered when improving quality of life in elderly people.

ABSTRACT: To examine satisfaction with quality of life among elderly people with active diseases, in-patients aged 65 and over in Tokyo Metropolitan Geriatric Hospital were interviewed. Multivariate analysis was performed using Hayashi's quantification theory (the 2nd family). The dependent variable was the question "are there any satisfactory aspects of your becoming old?" and 18 explanatory variable items including age, gender, activity of daily living (ADL) and physical and mental status. Among 68 patients examined, 49 cases fulfilled all the items. The correlation ratio was 0.353, and rate of correct discrimination was 77.6% (78.9% and 76.7% of positive and negative responses, respectively). The range and correlation coefficient of ADL and age were greater than those of other items. Affirmative answers increased with advancing age and loss of independency in ADL responded negatively. Poor prognosis also affected satisfaction with life. These results suggest that age and progression of disability are important factors which determine life satisfaction in elderly in-patients.
