Recently, poor posture (hyperkyphosis) has become a problem among children. This study investigated the effectiveness of an intervention (a spine mat) by measuring spinal alignment before and after the intervention in elementary school students. The study included 83 elementary school students. For the intervention, each participant was placed in a supine position on a bed and a spine mat was inserted ensuring that it adhered to the thoracic spine. The primary outcome variables included the thoracic kyphosis angle (TKA), upper thoracic angle, lower thoracic angle, lumbar lordosis angle (LLA), and sacral anteversion angle (SAA) measured in the standing and sitting positions using Spinal Mouse® before and after the intervention. Based on this evaluation, we assigned the participants to two groups: hyperkyphosis (n=25) and non-hyperkyphosis (n=58). Significant differences were observed between the pre-test and post-test TKA in the hyperkyphosis group in the standing position (pre-test: 45.3±4.5° and post-test: 40.8±9.0°, P<0.05). In the non-hyperkyphosis group, significant differences were observed between the pre-test and post-test LLA and SAA in the standing position. However, no significant difference was observed between the pre-test and post-test spinal alignment in the sitting position in both groups. The results of this study indicated that using a spine mat in elementary school children resulted in decreased TKA in the standing position only in the hyperkyphosis group, which exhibited a TKA of 40° or more after the intervention.

We focused on the traditional processing method which generates the superior quality of Yamato-shakuyaku. First, we assessed the historical literature written around Edo and Meiji period and rediscovered the traditional air drying method still inherited in Nara Prefecture. Then, we gathered and analyzed the data of medicinal plants production in Nara Prefecture among 1938 and 2019, and investigated the decline of local production and experienced agricultural techniques of peony through the transition of its yield. In order to visualize the ancient knowledge of crude drug manufacturers that contributes to the instruction of the skills for supply of seedlings, cultivation, and processing, we settled the meteorological observation devise at the outdoor drying shelf for 3 years, and recorded the real drying environment. When comparing the meteorological data with other cultivating area of peony using the estimated values of Agro-Meteorological Grid Square Data, the climate of Nara Prefecture was with high temperature and low humidity than other areas, and it seems to be quite suitable for air drying with adequate topography. The wind rose calculated by measured values of wind direction and wind speed showed the wind conditions in Nara that west wind was frequent in daytime and wind conditions are mildly but diversely changing. Among other producing areas of peony, the mechanical drying is major, whereas air-drying with low cost utilizing local environment features is still applied in Nara. We revealed the rationality of traditional methodology by digitization of meteorological factors which can be high added value.

Previous studies have reported that poor posture can induce various musculoskeletal disorders. Recently, poor posture in children has become a problem. This study aimed to determine the characteristics of sagittal spinal alignment in standing and sitting positions in elementary school students and how spinal alignment changes from standing to sitting position. Moreover, it clarifies how poor posture (hyperkyphosis) in the standing position affects sitting posture. This study was conducted among 83 elementary school students. The Spinal-Mouse® System was used to measure the thoracic kyphosis angle (TKA), upper thoracic angle (UTA), lower thoracic angle (LTA), lumbar lordosis angle (LLA), and sacral anteversion angle (SAA) in the standing and sitting positions. Hyperkyphosis was defined as a thoracic kyphosis angle of >40°. Participants were assigned to two groups: hyperkyphosis and non-hyperkyphosis. Significant differences were noted in all spinal alignment characteristics in both the positions. When spinal alignment was changed from standing to sitting, ΔUTA and ΔLTA correlated with ΔLLA and ΔSAA, respectively. A strong negative correlation was noted between ΔLLA and ΔSAA. In the sitting position, TKA, UTA, and LLA were significantly higher in the hyperkyphosis group than in the non-hyperkyphosis group. ΔUTA was significantly higher in the hyperkyphosis group than in the non-hyperkyphosis group when spinal alignment was changed from standing to sitting. The characteristics of sagittal spinal alignment in the sitting position were significantly different from those in the standing position. The study findings suggest that poor posture (hyperkyphosis) in the standing position affects the sitting posture.

Poor posture (thoracic hyperkyphosis) in children is reportedly caused by changes in their living environment. A previous study (conducted 30 years ago) reported that the position of the center of pressure (COP) in a child with an upright posture was approximately 40% from the heel. The present study aimed to determine the position and characteristics of the COP while standing in children aged 6–12 years. This study enrolled 83 elementary school students. A Win-Pod (Medicapteurs) platform was used to measure the COP. The COP position was expressed as a percentage from the heel as a relative ratio with a foot length of 100%. Spinal Mouse® was used to measure thoracic kyphosis, lumbar lordosis, sacral anteversion, and trunk inclination angles in the standing position. The COP position was 30.3±8.9% from the heel. We found positive correlations between the COP position, height, and weight. Further, the COP position was significantly more anterior in 28 upper elementary grade children (35.1 ± 9.2%) than in 25 middle (29.5 ± 8.6%) and 30 lower grade children (26.5 ± 6.7%). Regarding sex differences, the COP position was significantly more anterior in 46 boys (32.3 ± 9.8%) than in 37 girls (27.9 ± 6.9%). There was a weak positive correlation between the COP position and trunk inclination angle (r=0.251, p<0.05). Thus, we found that the COP position in modern children aged 6–12 years while standing was 30.3 ± 8.9% from the heel, indicating a shift toward the heel (backward) compared to that reported in previous studies.

We report two cases of inchinkoto treatment for obstructive jaundice via autoimmune pancreatitis (AIP). Case 1 : A 38-year-old male. After completion of treatment for Mikulicz disease, obstructive jaundice developed. A diagnosis of AIP was based on a high IgG 4 blood level and image views. T-Bil stayed above 20 mg/dl and there was no improvement by oral administration of prednisolone (PSL), ursodeoxycholic acid, or bilirubin adsorption therapy. Upon inchinkoto administration, T-Bil promptly fell to 3 mg/dL. Case 2 : A 77-year-old male. He suffered from itching and constipation, and blood data showed a pattern of obstructive jaundice. Image views suggested AIP, but a duodenal papillary biopsy could not provide a definitive diagnosis. Inchinkoto was administered, and the itching and constipation had mostly disappeared within 1 week. However, these symptoms recurred after one month. A definitive diagnosis of AIP was then reached based on a pancreas biopsy, and a PSL regimen was initiated. From these two cases, we consider that inchinkoto is useful for improving the symptoms of obstructive jaundice induced by AIP.

Studies have shown that postoperative disseminated intravascular coagulopathy (DIC) occurs in some patients with cardiac disease, acute aortic dissection, and ruptured abdominal aortic aneurysm. The specific pathophysiology of DIC in these settings are related to low cardiac function, shock, infection and sepsis as well as activation of coagulation cascade in the aneurysm sac or dissected aorta. A soluble form of recombinant human thrombomodulin (rhsTM) was approved in 2008 for the treatment of DIC. This report describes the safety and efficacy of rhsTM for the treatment of DIC in patients with cardiovascular disease operated in our department. Between October 2010 and March 2012, 35 patients with postoperative DIC were treated with rhsTM. Diagnosis of DIC was based on the diagnostic criteria for DIC of the Japanese Association for Acute Medicine (JAAM). During the first 6 months of the study period, after a diagnosis of DIC was made, the patients were treated with gabexate mesilate and antithrombin III, and if patients showed no improvement with conventional treatment, they received rhsTM for 6 days. During the last 10 months of the study period, patients received rhsTM soon after a diagnosis of DIC was made. Twenty seven patients survived for 28 days after rhsTM treatment, and the mortality rate was 22.9% (8/35). Patients who survived showed improvement in acute phase DIC scores, FDP levels, D-Dimer, fibrinogen and platelet counts during rhsTM treatment, but no improvement was observed in patients who died. No serious adverse events were found up to 28 days after the start of rhsTM administration. In conclusion, this study showed no adverse events of rhsTM, and further studies are needed to confirm that rhsTM administration is an effective therapeutic modality in the management of DIC after cardiovascular surgery.

We performed endovascular stent-graft placement on 39 patients with abdominal aortic aneurysms between 1996 and March 2002-a period of approximately 5 years (first half: until the end of June 1998, second half: July 1998 onward). Three patients in the first half of the period and 8 patients in the second half were 80 years or older. Two cases of mycotic aneurysm were observed. During the second half, we encountered high-risk cases in which the patients had complications such as coronary artery disease (5 patients), COPD (1 patient) and thoracic aortic aneurysm (4 patients). Although we had to switch to surgery in 3 patients during the first half of the period, we successfully placed stent-grafts in the other 36 cases (92%). Endoleaks were observed in 6 patients, and dissection of the iliac artery was observed in 5 patients (stents had been placed in all patients). In 50% of all cases in the first half of the period and 89% of all cases in the second half, stent-graft placement was successful and no endoleak was observed. During the follow-up period, 3 cases required additional treatment, and another 4 cases required surgery. Four patients died in hospital during the first half of the period, and 3 patients died during the following 3 years. The 3-year survival rate was 82%. It was considered that stent-graft placement for abdominal aortic aneurysms is particularly effective for high-risk patients, and that the results of this type of therapy will improve in the future.

This paper reports on a case in which a heavily-calcified so-called “porcelain aorta” (including the ductus arteriosus) was observed, together with a patent ductus arteriosus and aortic stenosis associated with a bicuspid aortic valve. A 76-year-old man had been referred to our hospital on a diagnosis of aortic stenosis. Since angiography revealed slight contrast in an area on the right side of the heart, echocardiography was performed and revealed patent ductus arteriosus. Severe circumferential calcification of the ascending aorta and aortic arch was observed on CT scans. Almost no calcification was observed in other areas. Aortic valve replacement and closure of the ductus arteriosus (transpulmonary approach) were performed by means of a balloon to temporarily occlude the aorta, as surgical clamping was impossible due to calcification. Hypothermic systemic perfusion and antegrade selective cerebral perfusion were used. The postoperative progress of the patient was good. Bicuspid aortic valve and patent ductus arteriosus are highly likely to be present in combination in cases of congenital cardiac anomaly, and it is therefore necessary to be particularly attentive when diagnosing such cases. It was considered that our patient, an adult suffering patent ductus arteriosus, was a rare case in which the calcified ductus arteriosus was observed and the calcification had spread to the ascending aorta.

In Kampo therapy for rheumatoid arthritis (RA), Keishi-ka-ryojutsubu-to, Keishini-eppi-itto and Keishi-shakuyaku-chimo-to are considered to be the primary formulas. However, it is often difficult to control arthritis with the primary formula alone. In this study, we administered 7.5g/day of Ji-daboku-ippo to 12 patients with RA, who had not responded sufficiently to the primary formula alone. Administration of the primary formula and other anti-rheumatoid drugs was also continued.
After three months of this supplemental administration of Ji-daboku-ippo, the mean±SE of the Lansbury's index significantly decreased from 45.3±5.8% to 33.3±3.8% (p<0. 01). After treatment for one year, a decrement in the Lensbury's index (of more than 20%) was seen in the four patients. These results suggest that supplemental administration of Ji-daboku-ippo is effective for patients who fail to respond sufficiently to the primary Kampo formulas used for RA.
