In order to establish signs in healthy subjects of pulses, tongue, and abdominal palpation determined by diagnostic techniques used in Kampo Medicine, we performed such diagnostic techniques in 71 subjects who had undergone a full physical examination and shown no abnormal signs from the viewpoint of western medicine. Pulses in men were often of medium depth, of medium speed, slightly large and substantive. There seemed to be at least two types of pulse in women, one was similar to the pulse signs found in men while the other was pulses of medium depth, of medium speed, small, and slightly deficient.
The tongue was pale pink, slightly damp, and slightly enlarged. The coating of the tongues was white or slightly white. Abdominal palpation often detected fullness, tenderness or discomfort of the hypochondrium (males and females), right paraumbilical tenderness (females), palpitation above the umbilicus (females), and softness below the umbilicus (males). A statistically significant difference between male and female subjects was noted in softness below the umbilicus which was more common in males, and in paraumbilical tenderness and palpitation above the umbilicus, which was more common in females. There was a significant correlation among signs of abdominal palpation.

Peripheral neuroblastic tumors (pNTs including Neuroblastoma, Ganglioneuroblastoma and Ganglioneuroma) are biologically and clinically heterogeneous. In order to develop efficient clinical treatment protocols of this disease, patients are stratified into different risk groups based on the combination of so-called prognostic factors. In this review, the prognostic factors are classified as clinically defined (Clinical staging and Age at diagnosis), histopathologically defined [International Neuroblastoma Pathology Classification (INPC) distinguishing Favorable Histology (FH) Group and Unfavorable Histology (UH) Group] and genetically/molecularly defined [MYCN oncogene amplification, DNA index, Segmental chromosomal aberrations, ALK (Anaplastic Lymphoma Kinase) mutation/amplification and Abnormal maintenance/elongation of telomeres], are outlined. According to the Children’s Oncology Group (COG) Neuroblastoma studies, the survival rate of patients in low- or intermediate-risk group is more than 90%. In contrast, the survival rate of patients in the high-risk group remains less than 50% despite currently available high-intensity and multimodal therapy. As described in the genetically/molecularly defined prognostic factors, tumors in the high-risk group, majority of which are classified into the UH group according to the INPC, are molecularly heterogeneous. Based on the recent progress of precision medicine along with our correlative analyses between molecular alterations and their morphological manifestations, four subgroups; i.e., MYC subgroup, TERT subgroup, ALT subgroup and Null subgroup, are identified immunohistochemically in the UH group for future management of the patients with this unique d isease.

OBJECTIVE: The aim of this study was to evaluate the clinical behavior and management outcome of recurrent endometrial stromal sarcoma (ESS). METHODS: A retrospective review of charts of 10 patients with recurrent ESS was performed and relapse-free interval, relapse site, treatment, response to treatment, duration of follow-up and clinical outcome extracted. Survival outcome measures used were post-relapse survival which was defined as the time from first evidence of relapse to death from any cause. Living patients were censored at the date of last follow-up. RESULTS: The median age and median relapse-free interval at the time of initial relapse were 51.5 years and 66.5 months, respectively. The number of relapses ranged from one to five. Sixteen surgical procedures for recurrent disease included nine (56.0%) complete resections. There was no statistically significant difference between initial recurrent tumors and second/subsequent recurrent tumors in the rate of complete surgery (44.4% vs. 71.4%, respectively, p=0.36). Of the eleven evaluable occasions when hormonal therapy was used for recurrent disease, disease control was achieved in eight (72.7%). There was no difference between initial recurrent tumors and second/subsequent recurrent tumors in disease control rate by hormonal therapy (85.7% vs. 50.0%, respectively, p=0.49). The 10-year post-relapse survival rate was 90.0% and the overall median post-relapse survival 119 months (range, 7 to 216 months). CONCLUSION: Post-relapse survival of patients with ESS can be expected to be >10 years when treated by repeated surgical resection and hormonal therapy or both.

In order to intervene in the management of pain of cancer from an early stage. Our palliative care team (PCT), including pharmacists, makes the ward rounds (screening rounds) of the patients receiving opioids at our hospital. The purpose of this study was to analyze the effects of screening rounds activity by the PCT and its current problems, and to explore how to resolve the problems. We retrospectively studied the records of 196 patients who had receivede interventions by the PCT, with regard to intervention status and prescription proposal (228 subjects) about drug therapy by us. Study groups were as follows: 103 patients to whom interventions were deliveed at the request of medical doctors (intervention request group) and 93 patients who had interventions by the PCT after PCT-screening rounds (screening group). PCT-screening rounds caused to increase the number of interventions by the PCT. After PCT-screening rounds, the cases of intervention started by the request of medical doctors, who had given no heed to PCT intervention, also increased in numher. In this study, some problems with palliative intervention were also brought to light. Even in the screening group where the PCT largely intervened, 33% of prescription proposal by the PCT was ignored. This problem may be, at least in part, due to inadequate communication between PCT and ward staff through an electronic medical recording card, leading to poor relationship between PCT and ward staff. In the future, the PCT needs to work cooperatively with ward staff through direct communication such as medical conference to perform better intervention.

The purpose of this study was to evaluate the effect of keishibukuryogan (KB) against the cognitive symptoms associated with silent brain infarction in a prospective cohort study. The subjects were 93 patients with silent brain infarcts who visited the Department of Japanese Oriental Medicine, University of Toyama, and its allied hospitals. They consisted of 24 males and 69 females, mean age (± S.E.) 70.0±0.8.Group SK (n=51) consisted of patients who used KB extract for more than6months per year. Group SC (n=42) consisted of patients who did not use Kampo formulas. The NS group (n=44) consisted of elderly subjects who had no silent brain infarction, 21 males and 23 females, with a mean age (± S.E.) of 70.7±0.7 years. Among the three groups, the revised version of Hasegawa's dementia scale, apathy scale and self-rating depression scale were compared between the study start and after three years. In the SK and SC groups, these scores, and the subjective symptom levels (head heaviness, headache, dizziness or vertigo, stiff shoulder) were also studied. The results showed that the self-rating depression scales at study start for the SK and SC groups were significantly higher compared to the NS group. In spite of the scores for the NS group increasing after three years, the SK group scores were significantly decreased compared to the SC and NS groups. KB was effective against head heaviness, which often complicates silent brain infarction. In the above mentioned, KB was effective in treating cognitive disorders and subjective symptoms related to silent brain infarction.

OBJECTIVES: Rheumatoid arthritis (RA) is characterized by chronic inflammation of the synovium, progressive erosion of the articular cartilage, and joint destruction. RA also causes secondary osteoporosis and muscle wasting. We investigated the effects of ibandronate (IBN), a bisphosphonate; eldecalcitol (ELD), an active vitamin D3 derivative; and combination treatment with both agents on secondary osteoporosis and muscle wasting using adjuvant-induced arthritis rats. METHODS: Arthritis was induced in 8-week-old male Lewis rats. Rats were randomized into 4 treatment groups and an untreated normal control group: IBN (subcutaneously, once every 2 weeks, 10 µg/kg), ELD (orally, once daily, 30 ng/kg/day), IBN + ELD, vehicle, and control. Paw thickness measurements were performed for evaluation of arthritis. The femur was scanned using dual-energy X-ray absorptiometry. Cross-sectional areas of left tibialis and anterior muscle fibers and the expression of MuRF1, atrogin-1, MyoD, and myogenin in the gastrocnemius muscle were measured to evaluate muscle wasting. RESULTS: IBN and/or ELD increased bone mineral density (BMD) in the femur. In addition, there was an additive effect of combination treatment compared with single treatments for BMD. However, IBN and/or ELD did not inhibit muscle wasting in adjuvant-induced arthritis rats. CONCLUSIONS: Combination treatment with IBN and ELD may be effective for secondary osteoporosis associated with RA. Other treatments are necessary for muscle wasting associated with RA. Studies in humans are needed to confirm these findings.

OBJECTIVES: While it has been pointed out that an anteroposterior (AP) view of the lumbar spine may lead to overestimation of the bone mineral density (BMD), a lateral view is expected lead to the early detection of BMD loss on scanning cancellous bone. Vertebral fracture is often seen in aged osteoporotic patients, and it is important to prevent this fracture. Therefore, we aimed to identify the optimal site for BMD measurement to assess the risk of vertebral fracture. METHODS: Forty-seven female patients with fresh osteoporotic vertebral fracture and BMD measurements were included in this study (Fracture group). As a non-fractured control group, 218 female patients with BMD measurements were enrolled (Control group). We compared BMD values based on AP and lateral views of the lumbar spine from L2 to L4 and the femoral neck. With a lateral view of the lumbar spine, we measured both the total vertebral body and vertebral body center, mainly composed of cancellous bone. RESULTS: BMD of the AP lumbar spine in the Fracture group was significantly lower than in the Control group (P < 0.05). In the subanalyses for comparisons between age-matched fracture and control groups, BMD of only the AP lumbar spine in the Fracture group was significantly lower than in the Control group (P < 0.01). CONCLUSIONS: AP lumbar spine BMD is optimal for assessing vertebral fracture occurrence.

OBJECTIVES: Reduced bone quality caused by vitamin C deficiency in older persons may lead to incidental fragility fractures during bisphosphonate treatment, although bisphosphonate increases bone mineral density (BMD). This study aimed to evaluate the effects of minodronate and ascorbic acid (Aa) on BMD, bone quality, and bone strength in Aa(-)deficient osteogenic disorder Shionogi (ODS) rats. METHODS: Six-month-old ODS rats were divided into four groups (n = 20 per group): (1) Aa supplementation (Aa(+)); (2) Aa(-)deficient (Aa(-)); (3) Aa supplementation and minodronate administration (Aa(+) + Mino); and (4) Aa(-)deficient and minodronate administration (Aa(-) + Mino). BMD, bone strength, bone histomorphometry, and bone quality determined using Fourier transform infrared spectroscopy imaging (FTIRI) were evaluated after 4 and 8 weeks. RESULTS: BMD was significantly higher in the Aa(+) + Mino group than in the Aa(-) group (p < 0.05). Bone strength was significantly higher in the Aa(+) and Aa(+) + Mino groups than in the Aa(-) group (p < 0.05). Furthermore, bone strength was significantly higher in the Aa(+) + Mino group than in the Aa(-) + Mino group (p < 0.05). Minodronate treatment irrespective of Aa supplementation significantly decreased bone resorption compared with the Aa(+) and Aa(-) groups (p < 0.05). No significant differences in the parameters evaluated by FTIRI were observed between the groups. CONCLUSIONS: Aa supplementation improved bone strength in ODS rats. Combined treatment with minodronate and Aa, but not minodronate alone, improved bone strength and increased BMD. Aa is required for bone health because it is essential for osteoblast differentiation.
