Urine tests, which are performed routinely as specimens can be collected without inflicting pain on patients at all, give plenty of information about health conditions quickly thanks to the recent advances in techniques for urinalysis. Nonetheless, the constituents of urine are liable to change, and so prompt examination is necessary. In the case of inpatients, it sometimes happens that examinations begin several hours after specimen collection. Behind this, there is no time frame set for collecting urine specimens which makes it difficult to deliver specimens to the examination room without delay.　　In this study, we investigated longitudinal changes in the contents of urine specimens voided by inpatients under some specific conditions. Furthermore, we examined the effects of those intestinal bacteria (E.coli, Proteus), which are often detected in urine, on glycosuria, and the changes in nitrite reduction reaction.　　Our findings showed that urine specimens containing such physiological and pathological factors as to influence urine tests were particularly subject to change with the passage of time. Therefore, when there is a need to preserve the specimens, chilled storage using a lidded container is required. It was slso found that between E -coli and Proteus in the urine a considerable difference was noted in time-dependent change of glycolysis and nitrite reduction reaction.

Magnetic resonance imaging (MRI) for diagnostic evaluation of the breast was performed in 61 patients who visted the Breast Clinic of our hospital and were suspected to have malignant tumors by physical examination and mammography between January and December 1999. In 58 patients undergoing histological diagnostic tests (8 with benignancy and 50 with breast cancer), we compared the imaging characteristics and the time-signal intensity curves acquired by dynamic imaging between benign and malignant lesions, and evaluated the usefulness of analyzing enhancement patterns on contrast MRI. Contrast MRI revealed strong tumor enhancement in all patients; the mean time required for the signal intensity to reach a peak was about 7 min in patients with benign tumors and about 2 min in those with breast cancer. Peripheral ring enhancement was observed in 40 of the 50 patients with breast cancer (80.0%), while such enhancement was not noted in any of the patients with benign tumors.
Although diagnosis of breast disease by imaging has primarily relied on mammography and ultrasonography, the pattern of contrast enhancement on dynamic MRI also appears to be useful for determining the treatment method of breast tumors.

AIMTo investigate the outcomes for Asian populations with locally advanced/clinical stage III prostate cancer (PCa) treated with currently prevailing modalities.

METHODSWe reviewed the record of 209 patients with clinical stage III PCa, who were treated at Niigata Cancer Center Hospital between 1992 and 2003. Treatment options included hormone therapy-combined radical prostatectomy (RP+HT), hormone therapy-combined external beam irradiation (EBRT+HT) and primary hormone therapy (PHT).

RESULTSThe 5- and 10-year overall survival rates were 80.3% and 46.1% in all cohorts, respectively. The survival rates were 87.3% and 66.5% in the RP+HT group, 94.9% and 70.0% in the EBRT+HT group and 66.1% and 17.2% in the PHT group, respectively. A significant survival advantage was found in the EBRT+HT group compared with that in the PHT group (P < 0.0001). Also, the RP+HT group had better survival than the PHT group (P = 0.0107). The 5- and 10-year disease-specific survival rates for all cases were 92.5% and 80.0%, respectively. They were 93.8% and 71.4% in the RP+HT group, 96.6% and 93.6% in the EBRT+HT group and 88.6% and 62.3% in the PHT group, respectively. A survival advantage was found in the EBRT+HT group compared with the PHT group (P = 0.029). No significant difference was found in disease-specific survival between the EBRT+HT and RP+HT groups or between the RP+HT and PHT groups.

CONCLUSIONAlthough our findings indicate that radiotherapy plus HT has a survival advantage in this stage of PCa, we recommend therapies that take into account the patients'social and medical conditions for Asian men with clinical stage III PCa.

We report a case of a 57-year-old woman with radiation proctitis (RP) treated by shiunko (SK) enema with promising outcomes. The patient underwent interstitial brachytherapy for anterior vaginal vault recurrence of uterine cancer. Nine months after the treatment, she had anal pain and was diagnosed with RP by clinical course and colonoscopy. The rectal ulcer was so severe that a surgeon proposed permanent stoma formation as one option, given eventual risk of rectovaginal fistula. The patient rejected stoma formation and opted for Kampo medicine. Though she took keishibukuryogankayokuinin for blood stasis at first, her anal pain and rectal bleeding gradually worsened. Thereafter, she mainly used SK enema, kyukikyogaito and magnesium oxide. Anal pain and rectal bleeding decreased after applying SK to the rectal wall per rectum. Magnetic resonance imaging (MRI) and colonoscopy findings of the rectal ulcer also improved. SK effectively reduced anal pain and rectal bleeding as well as stimulated tissue repair in our patient, and therefore SK is worth considering in the treatment of RP.

Shiunko, topical herbal ointment, has been used in Japan for hemorrhoid and skin wound such as scratch, incision and burn. We report two cases of radiation dermatitis with erosion, which have a good outcome after treatment with shiunko. Case 1 was 72-year-old man with radiation dermatitis of bilateral inguinal region caused by postoperative irradiation for bilateral inguinal lymph node metastases from penile cancer. Re-epithelization was observed in erosion on the 10th day after applying shiunko. It showed earlier recovery from radiation dermatitis than the cases treated with topical external medicine of azulene and/or steroid. Case 2 was 60-year-old man with the perianal radiation dermatitis with pain caused by pelvic radiotherapy for recurrence of advanced rectal cancer after chemotherapy. Shiunko gave rapid relief from anal pain and the patients felt no pain on the day subsequent to applying shiunko. Shiunko hastens analgesic effectiveness and improvement of wound caused by radiotherapy.
