In August 2001 we began to use WELPAS (a benzalkonium chloride solution) as part of our cost-containment drive, replacing self-made glycerol-added ethanol, which had been used for a long time to prevent nosocomial infections. Since then, blackish stains have become particularly noticeable here and there on the floorboards of the passageways in the hospital wards. The newly adopted quick-drying hand disinfectant was suspected as the culprit. To find the real cause of the dirt, we built a hallway similar to the real passageway for experiment. The disinfectant agents used were WELPAS, WELLUP (chlorhexidine gluconate), HIBISOFT (chlorhexidine gluconate), medicinal ethanol, cationic detergent solution, HIBITANE solution (chlorhexidine hydrochioride) and glycerol solution. These agents and distilled water were dropped on a limited area of the floor respectively for comparison of the degrees of dirt. The cationic detergent solution and WELPAS containing cationic detergent left blackish stains that were hardest to remove. From this finding, it was inferred that the cationic detergent solution was responsible for the dirt on the floor. So we decided to switch to a quick-drying hand disinfectant which does not contain cationic detergents. After considering economic benefit, we chose WELLUP which contains medicinal alcohol plus chlorhexidine gluconate and put it into actual use in October 2003. Since then, the hospitall floors have become unmistakalbly clean.

Pseudoaneurysm of the uterine artery is rare as a cause to delayed postpartum hemorrhage. Nowadays, uterine pseudoaneurysm is often treated by uterine artery embolization. The outcome is favorable. Here, we report a case of delayed postpartum hemorrhage following Cesarean section, which was caused from a rupture of uterine pseudoaneurysm. The patient was at the point of death from excessive bleeding but successfully treated by uterine artery embolization (UAE). In encountering a case of postpartum hemorrhage after Cesarean delivery or Dilation & Curettage, it is indispensable to check the abnormal blood flow in a color Doppler examination.

As a method of agility measurement under wide current use, the repeated side step is well-known. At present in Japan, a duration of 20 seconds is employed to test agility ; but it is often reported that the factor of endurance is included in this. When a diagnosis involving agility is made based on the performance of exercise, the duration of the time of measurement was controlled in order to avoid the mixing of other factors and to ensure measurement of as few factors as possible. The distance of step was made flexible according to the age. Since a constant distance makes the longitudinal tracing easier, the distance of step was also studied.
Side steps were tested and duration of measurement was examined based on determinations in 1857 subjects, Junior and Senior school boys and girls and male university students. During the 20 seconds of measurement, scores were recorded every 5 seconds to study the time course of the fluctuations of scores. Taking into consideration factors of endurance such as the endurance of the lower extremity system, the knee test was conducted to see the relationship between scores of the repeated side step and knee test values. As to the distance of the step, 200 high school girls were tested over a distance of 100cm ×2 and 120cm ×2, for 10 seconds each.
As to the time of measurement, the average score during the first 10-15 seconds after start tended to decrease. In the time course of fluctuations of the scores in each subject, a decrease in the fall of scorse was seen about 10 seconds after the start in approximately 55% of the test subjects.
Based on the assumption that the endurance of the lower extremity system participates in this, high and low groups with a significant difference in the endurance of the lower extremity at the level of P<0.001 were compared. While no difference was seen in the slope of the score increase over a 10-second period from the start, changes of scores were distinctly different between 10 and 20 seconds, the lower values in the low group being obvious. The endurance of the lower extremity system was then studied in the two groups with high and low scores in the side step between 10 and 20 seconds. In the group with high scores, the endurance of the lower extremity was high : and a significant difference at P<0.01 was noted in this index.
These results would definitely indicate that mixing of other factors is unavoidable under the current measurement duration of 20 seconds
As to the distance of the step, scores are apparently different even in the same test subject, depending upon the distance of the step. The scores are also different depending upon the body length.
In both of the two groups, however, the scores for each different distance of the step showed a high correlation between each other, giving a correlation coefficient of γ= 0.88 in the group with high body length and γ= 0.82 in the group with low body length, indicating a high correlation.
Based on the diagnosis of agility and performance of exercise, in order to obtain the results of measurement of as simple a factor as possible, the agility time measurement is corrected to 10 seconds ; and the distance of the step is made constant at 100cm×2 regardless of the age, to a distance without unnatural effort even by a primary school pupil, in order to obtain a better diagnosis and tolerance for exercise for the desirable development and maintenance of agility.
The influence of body height on the score should be studied in the future.

Dialysis treatment was first introduced in the convalescent rehabilitation ward after the medical fee revision in April 2012 in Japan. In this study, we examined 4 stroke patients who underwent rehabilitation in the convalescent rehabilitation ward while receiving dialysis. We collected information on the patients' age, sex, disease, dialysis period, duration of hospitalization during the acute and recovery phases, the number of units of exercise, discharge destination after hospital, complications, and their Functional Independence Measure (FIM) scores. The average age of the subjects( 2 men and 2 women) was 71.0±9.5 years. Two of the 4 patients had cerebral hemorrhage and the other 2 had cerebral infarction. The dialysis period was 16.8±21.7 months. The duration of hospitalization during the acute phase was 50.0±20.3 days, while that in the convalescent rehabilitation ward was 120.0±28.2 days. The average exercise amount per day was 6.01±1.17 units in the convalescent rehabilitation ward. The total FIM score was 59.3±19.2 at admission and 94.5±27.0 at discharge. The FIM efficiency was 0.29±0.16. In all cases, the discharge destination was home. Three of the subjects showed progression of their renal anemia. One subject developed shunt vessel stenosis and one developed delirium as complications. We conclude that rehabilitation in the convalescent rehabilitation ward for dialysis is beneficial to patients due to the increased amount of exercise that they receive. In addition, such rehabilitation enables the patients to return home in good health, similar to the case of non-dialysis patients.

The diagnosis of pituitary carcinoma cannot be made easily histologically, and most cases of pituitary carcinoma are diagnosed only after the clinical detection of metastasis. Distant metastasis of pituitary tumor occurs in 0.1% to 0.2% of cases and has been reported in the liver, bone and central nervous system, with only one case of metastasis to the cauda equine reported. This study describes a rare case of the drop metastasis of adrenocorticotropic hormone-producing pituitary adenocarcinoma to the cauda equina, causing cauda equina syndrome.

OBJECTIVE: Recent investigations have revealed DNA mismatch repair (MMR) gene mutations are closely related with carcinogenesis of endometrial cancer; however the impact of MMR protein expression on prognosis is not determined. Correlations between MMR-related protein expression and clinicopathological factors of endometrial cancers are analyzed in the present study. METHODS: A total of 191 endometrial cancer tissues treated between 1990 and 2007 in our hospital were enrolled. Immunoreactions for MSH2, MLH1, MSH6, and PMS2 on tissue microarray specimens and clinicopathological features were analyzed retrospectively. RESULTS: Seventy-six cases (40%) had at least one immunohistochemical alteration in MMR proteins (MMR-deficient group). There were statistically significant differences of histology, International Federation of Gynecology and Obstetrics (FIGO) stage, and histological grade between MMR-deficient group and the other cases (MMR-retained group). Response rate of first-line chemotherapy in evaluable cases was slightly higher in MMR-deficient cases (67% vs. 44%, p=0.34). MMR-deficient cases had significantly better progression-free and overall survival (OS) compared with MMR-retained cases. Multivariate analysis revealed MMR status was an independent prognostic factor for OS in endometrial cancers. CONCLUSION: MMR-related proteins expression was identified as an independent prognostic factor for OS, suggesting that MMR was a key biomarker for further investigations of endometrial cancers.

OBJECTIVE: To assess the use of colony-stimulating factors (CSFs) in patients with ovarian cancer who receive adjuvant paclitaxel and carboplatin chemotherapy in clinical practice and to assess whether the frequency of CSF use differs among hospitals in Japan. METHODS: CSF use in patients with ovarian cancer who received first-line paclitaxel and carboplatin was analyzed retrospectively using data from the Japanese hospitalization payment system. RESULTS: A total of 1,050 patients at 104 hospitals were identified. The median age was 60 years (range, 22 to 88 years). Of these, 163 patients (15.5%) were diagnosed with neutropenia and 134 patients (12.8%) received CSFs. Among the patients who received CSFs, 125 (93%) received them for the treatment of neutropenia without fever and 1 received them for febrile neutropenia. In total, CSFs were administered for 272 cycles of chemotherapy. Among them, CSFs were used as treatment for neutropenia without fever in 259 cycles (95%), as prophylaxis (primary or secondary) in 12 cycles (4%), and as treatment for febrile neutropenia in 1 cycle. Among hospitals, a median of 4.0% of patients received CSFs with an interquartile range of 25% (Q1, 0%; Q3, 25%). A logistic random effects model showed that the variation in the proportion of patients receiving CSFs among the 104 hospitals was 2.0 (p<0.001), suggesting that the use of CSFs varied across hospitals. CONCLUSION: Most patients received CSFs for neutropenia without fever. Standardized and evidence-based use of CSFs is critically required among hospitals in Japan.

OBJECTIVE: Compared with serous adenocarcinoma (SAC), clear cell carcinoma (CCC) often shows chemo-resistance, which would potentially lead to a poor prognosis. On the other hand, there have been arguments over prognoses of CCC and SAC disease. In the present study, multivariate analysis to compare prognosis of CCC patients with that of SAC was aimed for the patients selected from central pathologic review. METHODS: Between 1984 and 2009, a total of 500 ovarian cancer patients were treated at our university hospital. Among them, 111 patients with CCC and 199 patients with SAC were identified through central pathological review. Overall survival and progression-free survival were compared using Kaplan-Meier method, and prognostic factors were investigated by multiple regression analyses. RESULTS: Median age was 52 years for CCC and 55 years for SAC (p=0.03). The ratio of stage I patients were significantly higher in CCC compared with SAC (55% vs. 13%, p<0.01). Among evaluable cases, response rate was significantly lower in CCC than that in SAC (32% vs. 78%, p<0.01). No significant differences of progression-free survival and overall survival were observed in stage I patients; however, prognoses of CCC were significantly poorer than those of SAC in advanced-stage disease. In stage II-IV patients, not only residual tumors and clinical stages, but also clear cell histology were identified as predictors for poor prognosis. CONCLUSION: Clear cell histology was identified as a prognostic factor for advanced-stage ovarian cancers. Histologic subtypes should be considered in further clinical studies, especially for advanced epithelial ovarian cancers.
