RESUMEN

BACKGROUND: School urinary screening has been performed in Japan. METHODS: Ikeda City and Toyono Town introduced, in 2012 and 2013, urinary protein/creatinine (Cr) ratio measurement into the urine-screening protocols designed for students aged between 4 and 15 years. For each student whose urinary protein/Cr ratio was ≥ 0.15 g/gCr (positive case), an appointment was made with a specialist at Ikeda City Hospital. The results of these screening urinalyses conducted through 2018 are summarized. RESULTS: 14,606 junior high and elementary school students aged between 6 and 15 years were included. On average, they underwent 4.16 screening tests. 77 positive cases were detected, and seven students were diagnosed with high-risk chronic kidney disease (CKD). Of these, four underwent renal biopsy, and two, one, and one were diagnosed with IgA nephropathy, MPGN, and FSGS, respectively. In three students, detection of CKD would have been difficult without urinary screening. Incident rates of high-risk CKD and IgA nephropathy are estimated as 11.5 and 3.3 cases/100,000 students/year. 78.0% of positive cases without high-risk CKD showed no urinary abnormality after one year. 2301 kindergarten students aged between 4 and 6 years received an average of 1.74 screening urinalyses; none was positive or high-risk CKD. The estimated cost of detecting one high-risk CKD student whose detection would have been difficult without this screening was 3,156,711 Japanese yen. CONCLUSION: School urinary screening using the urinary protein/Cr ratio can efficiently refer to a specialist. It detects a few children with high-risk CKD early with spending high cost.

RESUMEN

Using 415 residual blood samples subjected to (1→3) -ß-D-glucan assay, we studied the correlation of measurement results between Fungitec G Test MKII "Nissui" (Nissui Pharmaceutical Co., Ltd., Tokyo) and its predecessor, Fungitec G Test MK (Seikagaku Corporation, Tokyo), which is now out of production. Their major difference is that MK II uses reagents derived from blood cells of Limulus polyphemus, the American horseshoe crab, whereas MK used those of Tachypleus tridentatus, an Asian horseshoe crab. Passing-Bablok analysis showed a linear regression with nearly one-to-one correspondence (slope=1.065, intercept=-0.287) between the two test kits over the regular range of measurements (4.0 pg/ml -500 pg/ml ). This was also true when data were subdivided and analyzed in the low to medium (≦150 pg/ml ) and in the low range (≦50 pg/ml ). There were several cases, however, that showed a wide discrepancy between the pair of measurements. This discrepancy is believed to be due in part to the difference between Limulus and Tachypleus in their reactivity to ß-glucans with diverse side chains. Despite of this, the even distribution on either side of the regression line of those samples that are associated with deep fungal infection and the abrupt disappearance of such samples below 20 pg/ml attest that MK II "Nissui" is an acceptable successor of MK.

RESUMEN

Few reports on malignant transformation of adenomyosis are available, and endometrioid adenocarcinoma arising from cystic adenomyosis is further rarely reported. We report a case of a 67-year-old asymptomatic woman who was referred to our hospital for evaluation of a cystic lesion in the pelvis, which had been diagnosed as cystic degeneration of leiomyoma for 3 years. Magnetic resonance imaging revealed a cystic mass measuring 11 cm in diameter, which was contiguous with uterine myometrium. The lesion contained solid areas enhanced on gadolinium-enhanced T1 -weighted imaging. Transabdominal simple total hysterectomy with bilateral salpingo-oophorectomy was performed. Pathological examination revealed endometrioid adenocarcinoma arising from cystic adenomyosis. The patient underwent six courses of adjuvant combination chemotherapy with paclitaxel and carboplatin. No metastasis or recurrence has been demonstrated for 16 months following surgery. Our case demonstrates that cystic adenomyoma possesses the risk of malignant transformation, indicating the importance of long-term follow-up with imaging examination.

RESUMEN

This is a retrospective study of fifteen cases of primary peritoneal carcinoma who were treated between 2001 and 2010 in our hospital. The median age at the time of diagnosis was 63 years(range, 40 to 79 years). Three patients had clinical stage II disease, eleven patients had stage III disease, and one patient was unstaged. The serum CA125 values at pretreatment were elevated in all patients, with a median value of 4,144. 8 U/mL(range, 102. 8 to 23, 611. 0 U/mL). Optimal debulking was possible in 9 of the 15 patients. All patients were treated with paclitaxel and carboplatin chemotherapy during the preoperative and/or postoperative period. All patients at stage II disease were alive without evidence of disease at the time of evaluation(2 patients>5 years, 1 patient>3 years). Four patients with stage III disease had died from the disease less than 3 years after the first treatment. The results of our study showed poor survival for the group with stage III disease, but good survival for the group with stage II disease.

RESUMEN

Ovarian clear cell adenocarcinoma (OCCA) is known to have a worse prognosis than ovarian serous adenocarcinoma due to its poor response to conventional platinum-based chemotherapy. Idiopathic thrombocytopenic purpura (ITP), which usually reveals severe thrombocytopenia, is a common autoimmune disorder. However, to date very few cases of ovarian cancer associated with ITP have been reported in the literature. We report a case of a 57-year-old woman who developed OCCA 14 years after the diagnosis of ITP. The patient presented with abdominal distention and mild tenderness. We performed the operation with high-dose immunoglobulin therapy preoperatively, and diagnosed OCCA. Postoperatively, six cycles of cytotoxic chemotherapy with irinotecan hydrochloride plus cisplatin were performed every 4-5 weeks without thrombocytopenia. We conclude that combination chemotherapy with irinotecan hydrochloride plus cisplatin is useful for a case of OCCA associated with ITP.

RESUMEN

PURPOSE: The purpose of the current study was to evaluate the difference in prognostic factors between stage IB and II uterine cervical carcinoma patients treated with postoperative radiation therapy. PATIENTS AND METHODS: Between May 1988 and May 1998, a total of 94 patients including 47 patients with stage IB and 47 patients with stage II uterine cervical carcinoma were treated with postoperative radiation therapy at Tokyo Metropolitan Komagome Hospital. All patients were treated with 10 MV X-rays using an anterior-posterior parallel opposed field which covered the whole pelvis. Fractionation was 2 Gy per day, five fractions per week, to a total dose of 50 Gy. RESULTS: The 5-year overall survival rates of stage IB and II were 89.4% and 79.3%, respectively. In multivariate analysis for all patients, lymph node status, histology, and surgical margin status were recognized as prognostic factors. Limited to stage IB patients, lymph node status was the only independent prognostic factor. However, for stage II patients, tumor histology was also an independent prognostic factor. CONCLUSIONS: The prognostic factors of stage IB and II were different. Tumor histology was only associated with stage II patients. These findings suggested that tumor histology might have played a different role as tumor stage progressed. However, further studies with large numbers of patients will be required to confirm these results.
