Nephroblastomatosis (NBM) is a precursor of Wilms tumor. We herein report a case in which Wilms tumor was initially suspected and the affected kidney was removed.The tumor was subsequently diagnosed as intralobar NBM and a favorable outcome was achieved with postoperative chemotherapy. A 2-year-old boy who presented with gross hematuria was found to have an enlarged left kidney with hydronephrosis.Needle biopsy of the left kidney suggested Wilms tumor and left nephrectomy was performed. The tumor was histopathologically diagnosed as intralobar NBM.Although NBM is regarded as a precancerous lesion, a definite treatment plan has not yet been established. In the present case, we used a similar chemotherapy regimen to that for Wilms tumor. Eight years after the completion of chemotherapy, Wilms tumor has not developed or recurred. Appropriate management plans need to be developed by accumulating similar cases.

Background: Febrile neutropenia (FN) remains an important complication in pediatric cancer patients. The present study compared the efficacy of meropenem (MEPM) and piperacillin/tazobactam (PIPC/TAZ) with or without intravenous immunoglobulin (IVIG) as second-line therapy for FN in pediatric patients. Methods: As first-line treatment for FN, 394 episodes in 99 patients were randomly assigned to receive PIPC/TAZ (360 mg/kg/day, maximum 18 g/day) or MEPM (120 mg/ kg/day, maximum 3 g/day). Eighty-four episodes in 42 patients were judged as failures, and, thus, were enrolled for second-line treatment. In second-line treatment, antibiotics were switched to MEPM or PIPC/TAZ, and episodes were further randomized for treatment with or without concomitant IVIG at 100 mg/kg/day (maximum 5 g/day) for 3 consecutive days. Results: The total success rate of second-line treatment was 50.0% (52.0% in PIPC/ TAZ and 47.2% in MEPM with or without IVIG, P=0.826). The success rates of patients treated with (IVIG+ group) and without IVIG (IVIG− group) were 53.8 and 46.7%, respectively (P=0.662). In the IVIG+ group, the success rate of patients younger than 8 years old was 78.6%, which was significantly higher than that of those aged 8 years and older (40.0%, P=0.043). Conclusion PIPC/TAZ and MEPM were equally effective as second-line treatment. Concomitant IVIG was also effective, particularly in patients younger than 8 years.

OBJECTIVE: The aim of this study was to investigate the clinical characteristics of young patients with stage I clear-cell carcinoma (CCC) and evaluate the prognostic factors and effects of fertility-sparing surgery (FSS) using propensity score (PS) adjustment. METHODS: We conducted a regional multi-institutional study between 1986 and 2017. Among 4,277 patients with ovarian tumor, clinical and pathological data of 103 fertile women with stage I unilateral CCC were collected. We evaluated survival and reproductive outcomes in these patients. Additionally, to analyze the effects of FSS, baseline imbalance between patients with and those without FSS was adjusted with an inverse probability of treatment weighting using PSs involving independent clinical variables. RESULTS: The mean patient age was 39.4 years, and the median follow-up period for surviving patients was 55.6 months. In multivariate analysis, stage IC2/IC3 (vs. IA/IC1) was the only independent prognostic factor for recurrence-free survival (RFS) and overall survival (OS). FSS was not associated with poorer prognosis when compared to the prognosis with non-preserving surgery with regard to both RFS and OS. No statistical difference in survival outcomes between FSS and other approaches was confirmed after PS adjustment. Among patients who underwent FSS, four deliveries with healthy neonates were noted without any gestational complications. CONCLUSION: FSS can be considered in stage I CCC, specifically in stage IA and IC1 patients who strongly desire to have children in the future. Further clinical research is needed to clarify the optimal application of FSS for CCC.

The patient was a 45-year-old woman who began suffering from pain in her extremities 1 year and 6 months previously, and who received Oketsu-reducing Kampo. Her pain disappeared in a year. Six months after her treatment ended, she visited our hospital again complaining of the same symptom. Due to strong signs of Oketsu, we prescribed her a Kampo that reduces Oketsu, but her pain largely persisted. On re-examination, we noticed that her condition had occurred during the rainy season on both instances and speculated that high humidity and strong ‘wind' may be the reason. Therefore, Byakujutsubushito was prescribed for her, and her pain disappeared in 2 weeks. However, in the following rainy season, she visited us again complaining of the same pain, and Byakujutsubushito was again administered, and that relieved her from pain in 11 days. Although it is stated that Byakujutsubushito is useful for the treatment of pain resulting from dampness and ‘wind', there are very a few reports on this in the Kinkiyoryaku text. Nowadays, we live in air-conditioned spaces, and high humidity results in ‘cool wind’ and exterior dampness. Frequent movement in and out of such spaces worsens extremity pain, and we believe that the incidence of this condition is increasing. And we believe that Byakujutsubushito is one of the most useful formulations for the treatment of this condition that occurs during rainy season.

We report two cases of unexplained thoracodorsal pain, which were successfully treated with the Kampo formulations karogaihakuhakushuto and karogaihakuhangeto. In case 1, the patient was a 67-year-old man. Left thoracodorsal pain appeared in this patient two months after the administration of chemotherapy for transverse colon cancer with hepatic metastasis. Bone metastasis was ruled out by bone scintigraphy, but the cause of the pain was still unknown. The Kampo formulation karogaihakuhakushuto was prescribed and the pain was reduced after two weeks, and disappeared within three months. In case 2, the patient was a 40-year-old man. Right thoracodorsal pain appeared in the right hypochondriac region without an apparent cause. Examinations, such as computed tomography and upper gastrointestinal endoscopy, were conducted, but the cause of the pain remained undiagnosed. The pain was not improved with pain killers, karogaihakuhakushuto was prescribed, and the pain was then reduced in about a month. The authors considered thoracodorsalpain as already described in the great classic Kinkiyoryaku (Chin Keiu Yao Lueh). We then prescribed karogaihakuhakushuto and karogaihakuhangeto, which resulted in immediate clinical improvement. These clinical courses indicate that the formulae can be effective for the treatment of thoracodorsal pain of unknown origin. Furthermore, the effect of herbal medicines and herbal decoctions boiled with rice wine may make it possible to have a more imminent effect on thoracodorsal pain.

Standardizing Kampo medical findings is a significant challenge in Kampo medical circles. These findings are fundamental to Kampo diagnosis. This paper introduces our attempt to standardize these findings in a specialized Kampo medical service facility.
We started our project with verbal standardization. Nine medical doctors, all of whom were Kampo advisors or Kampo specialists, discussed issues such as subjective and objective findings, including those of the tongue, pulse, and abdomen, as well as the selection of target items, criteria for judgments on each item, and associated issues. When discussing the above issues, descriptions in prominent traditional Kampo texts were given most importance, and the wisdom of famous Kampo doctors since the Showa period was also given weight. In addition, we focused attention on clarifying the criteria for making judgments.
One hundred and twenty items were selected as subjective Kampo findings. We selected 12, 6 and 10 items as objective Kampo findings in the tongue, pulse, and abdomen, respectively, and provided criteria for judgments with each.
Our next challenge is to spread these standardizations in Kampo medical circles.

We analyzed the clinical features of 21 cases with drug-induced liver injury due to Kampo medicines between the years 2000 and 2009 in our institute. The mean age in these cases was 55.2 ± 13.4 years. Five of the cases were men, and 16 were women. In 17 of the 21 cases, drug-induced liver injury had occurred within 3 months after beginning Kampo medicines. There were no subjective symptoms in 11 cases. Nine cases of both hepatocellular injury, and of mixed-type injury were seen. Causative Kampo medicines included an Ogon (Scutellariae Radix) component in 19 cases. A drug-induced lymphocyte stimulation test (DLST) was performed in 5 cases. The test was positive for Kampo medicines in only one of the 5 cases. Liver injury improved or normalized in 18 cases (85.7%) after discontinuing causative Kampo medicines. In another 2 cases, liver injury normalized after changing a Kampo medicine to the same prescription without Ogon. These results suggest that even if patients complain of no symptoms we must perform blood tests to check liver function within 3 months of prescribing Kampo medicines, especially those including Ogon, to facilitate early diagnosis of drug-induced liver injury.

Soshikokito is a Kampo formulation used in the treatment of bronchial asthma, especially in those patients with hot flushes and cold sensation in their feet. But there is also a description in classical textbooks for its usage for the treatment of tinnitus. We report two typical cases of prolonged tinnitus treated successfully with soshikokito. Case1was a 70-year-old woman who visited our clinic complaining of tinnitus, dizziness and insomnia. She had a history of bilateral otitis media in her childhood, and had been suffering from tinnitus after being operated for it. The tinnitus had worsened during the three months prior to her first visit to us. After 3 months' treatment with soshikokito with additional shisoyo, her symptoms improved, so much so that after 8 months, she could live her life normally. Case 2 was a 58-year-old man who presented with tinnitus, hearing disturbance and a sense of irritation. He also complained of insomnia and cold sensation in his limbs. After1month's treatment with soshikokito with additional shisoyo and bushi, most all of his symptoms resolved. In addition, we also evaluated the clinical efficacy of soshikokito for prolonged tinnitus, retrospectively, and found that it was effective in five out of the ten cases we treated with this formulation. Most of the successfully treated patients presented with hot flushes or cold sensation in their feet. These case reports suggest that soshikokito may be a useful formulation for the treatment of not only bronchial asthma, but also of prolonged tinnitus.

We report four cases which were successfully treated with keishikyokeikabukuryobyakujutsuto. Case 1 was a 53-year-old female who presented with a 15-year history of fatigue, headache and shoulder stiffness. After 1 month's treatment with keishikyokeikabukuryobyakujutsuto, her complaints improved remarkably. Case 2 was a 29-year-old female who was suffering from allergic rhinitis. After 6 month's treatment with keishikyokeikabukuryobyakujutsuto, her symptoms completely resolved. Case 3 was a 37-year-old female who was diagnosed with Meniere's disease. Some formulas had been prescribed before, but provided no relief. After the start of treatment with keishikyokeikabukuryobyakujutsuto, however, the patient's symptoms resolved completely within 2 weeks. Case 4 was a 50-year-old female who presented with tension headache. After 2 week's treatment with keishikyokeikabukuryobyakujutsuto, her headache had almost completely resolved. Most of the cases presented with slight epigastric tenderness and superficial-like symptoms such as headache and shoulder stiffness. Many of them also showed symptoms suggestive of fluid imbalances in the body, such as dizziness, rhinorrhea and teeth marks on both sides of the tongue. Keishikyokeikabukuryobyakujutsuto is a useful formula for patients with superficial-like symptoms accompanied by disorders of the body fluid homeostasis.

OBJECTIVESTo investigate the prevalence of non-alcoholic fatty liver disease (NAFLD) in children and its relationship to metabolic syndrome, insulin resistance, and waist circumference (WC).

METHODSThis was a population-based cross-sectional, case-control study. Cases were selected among students of a primary and junior high school, respectively, and age- and sex-matched control subjects were selected randomly (ratio of cases to control subject was 37:113).

RESULTSOf the 846 students, aged between 6 and 15 years, enrolled in the study and screened by ultrasonography, 37 children were diagnosed as having NAFLD (score >/= 1). There was a significant sex difference in the prevalence of NAFLD(P = 0.003). The trend test revealed a strong dose-response relationship (P < 0.001) between pediatric NAFLD and the number of the proposed components of pediatric metabolic syndrome in Japan (MetS-JC), such as a clustering of the components of MetS-JC. Additionally, the linear trend of the odds ratios (ORs) with increasing percentile of the homeostasis model assessment-insulin resistance (HOMA-IR) was statistically significant (P < 0.001). However, when WC was added to the logistic model, the ORs were no longer significant, whereas WC turned out to be an independent risk factor for NAFLD regardless of the HOMA-IR index.

CONCLUSIONThe prevalence of NAFLD in children and adolescents is closely related to metabolic syndrome, insulin resistance, and WC.
