Introduction
 During the course of primary health care activities in Khammouane province of Lao PDR by non- profit organization, international support and partnership for health, an exceedingly high infant mortality rate was recognized in some villages. As thiamine deficiency was strongly suspected for the main cause of the high mortality, the household survey with an emphasis on nutritional aspect and the measurement of thiamine level in the blood of mothers as well as their breast-milk were carried out for the confirmation.
Methods
 The survey was conducted at Sibounhouane sub-district (Group 1) with the highest infant mortality and Hatkhamhieng sub-district (Group 2) with the lowest mortality. Fifty families of the two groups, each consisting of randomly selected 25 families with less than one year old infant(s) were interviewed by using prepared questionnaire. The body weight of both mother and infant was measured and blood and milk were taken from the mother.
Results
 The ethnic minorities of the group 1 consisted of Lao Lum (44%) and Lao Theung (56%), whereas only Lao Lum in the group 2. The economical indicators and the mother's educational level in the group 1 were inferior to those in the group 2. There was no significant difference in the methods of preparing staple glutinous rice, likely to flux thiamine and intake of thiaminases between the two groups. High infant mortality rate was documented in the group 1 whose clinical symptoms were mostly consistent with those of infantile beriberi. The concentration of thiamine in the blood and milk of mothers in both groups were considerably lower and significant reduction of thiamine level was observed in the group 1 than the group 2. Nevertheless, both groups of those infants tended to be inadequately fed with the foods except for breast-milk during their early infantile phase.
Conclusions
 The low concentration of thiamine in the blood and milk of mothers was strongly suggestive that infantile beriberi due to thiamine deficiency was the principal cause of the infant mortality in the study region. We hereby surmise that thiamine deficiency could be extensively prevalent in Lao PDR than the currently studied areas because of their traditional preparing methods of staple dietary rice, postpartum food taboos and intake of thiaminases. For the prevention of infant death due to severe thiamine deficiency, necessary measures including the exchange of information among the institutions concerned, adequate thiamine supplementation and nutritional counseling have to be urgently adopted.

We examined the effect of the liaison critical pathway for stroke among the inpatients in an acute hospital (AH) from 2007 to 2008. The average length of hospital stay in the AH was reduced by 5.7 days compared with 2006 by means of the critical pathway. Among 155 patients who had been transferred from the AH to a convalescent rehabilitation ward (CRW), 148 were discharged from the CRW. Ninety-seven patients returned home and 44 patients were transferred from the CRW to a nursing home type unit or an institution. One patient died in the CRW, six were returned to the AH. From among the clinical factors, that included sex, age, modified Rankin Scale (mRS), total, motor and cognitive scores of Functional independence measure (FIM) at discharge from the AH, total FIM scores and FIM gain at discharge from the CRW, mRS at discharge from the AH and total FIM scores at discharge from the CRW exerted an influence on outcome. Patients living with their spouses and / or children before the onset of stroke were more inclined to return home.

Otsujito is a well-known Kampo medicine for treatment of hemorrhoidal diseases. In the current report, we present end results for a case of enterocutaneous fistula treated with Kampo medicine in accordance with traditional “sho” indications.
An 81 year-old female developed abdominal wall-intestinal fistula right immediately following partial colectomy due to ischemic sigmoid colic perforation 12 years previously. Two years later, she had a fistulectomy and repair using intraperitoneal mesh for abdominal recruitment. Eight years after repair of the enterocutaneous fistula, she had peritonitis caused by the tardive intraperitoneal mesh infection. Since then, she has had frequent repeated ileus and received conservative treatment for two years. Several local operations and abdominal drainages were performed after transfer to Aizu Medical Center. Kigikenchuto was provided for wound healing for approximately 1 year, and one fistula was finally identified. Otsujito dramatically decreased the leakage of intestinal juice and closed her enterocutaneous fistula.
Angelicae Radix as an anti-inflammatory agent, and Cimicifugae Rhizoma as originally indicated, may have played pivotal roles in this case with Otsujito.

Background: and Purpose To clarify the effect of perampanel (PER) on sporadic amyotrophic lateral sclerosis (sALS) progression, the relationship between the changes in Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) scores and serum PER concentrations was investigated. Methods: 12 patients with sALS from our hospital who agreed to participate and completed the PER for sALS randomized phase 2 study were included. After completing the study, we retrospectively obtained serum PER concentration data from the patients. Based on their mean PER concentrations, we divided the patients who had been taking PER into two groups:four patients with a mean PER concentration of ≥400 ng/mL were assigned to the H group, and three with a mean PER concentration of <400 ng/mL were assigned to the L group. The control group consisted of five patients who had been taking a placebo. We obtained the ALSFRS-R scores of each patient at 36 and 48 weeks after randomization. The differences in ALSFRS-R scores at baseline (0 weeks) and each subsequent week were used in the analysis. Results: At 48 weeks, there were no differences in the degree of deterioration of the bulbar, upper and lower limb, and respiratory ALSFRS-R subscores and total ALSFRS-R score. However, at 36 weeks, the bulbar subscore was significantly lower in the H group than in the control group (p=0.032). Conclusions Because high PER concentrations may exacerbate bulbar symptoms in patients with sALS, serum PER measurements may be beneficial when patients with sALS are taking PER.

PURPOSE: In cardiac 2-[F-18]fluoro-2-deoxy-D-glucose (FDG)-positron emission tomography (PET) examination, interpretation of myocardial viability in the low uptake region (LUR) has been difficult without additional perfusion imaging. We evaluated distribution patterns of FDG at the border zone of the LUR in the cardiac FDG-PET and established a novel parameter for diagnosing myocardial viability and for discriminating the LUR of normal variants. MATERIALS AND METHODS: Cardiac FDG-PET was performed in patients with a myocardial ischemic event (n = 22) and in healthy volunteers (n = 22). Whether the myocardium was not a viable myocardium (not-VM) or an ischemic but viable myocardium (isch-VM) was defined by an echocardiogram under a low dose of dobutamine infusion as the gold standard. FDG images were displayed as gray scaled-bull's eye mappings. FDG-plot profiles for LUR (= true ischemic region in the patients or normal variant region in healthy subjects) were calculated. Maximal values of FDG change at the LUR border zone (a steepness index; S(max) scale/pixel) were compared among not-VM, isch-VM, and normal myocardium. RESULTS: S(max) was significantly higher for n-VM compared to those with isch-VM or normal myocardium (ANOVA). A cut-off value of 0.30 in Smax demonstrated 100% sensitivity and 83% specificity for diagnosing n-VM and isch-VM. S(max) less than 0.23 discriminated LUR in normal myocardium from the LUR in patients with both n-VM and isch-VM with a 94% sensitivity and a 93% specificity. CONCLUSION: S(max) of the LUR in cardiac FDG-PET is a simple and useful parameter to diagnose n-VM and isch-VM, as well as to discriminate thr LUR of normal variants.

In patients with unresectable hepatocellular carcinoma (HCC) without both macrovascular invasion and extrahepatic metastasis, the initial treatment choice recommended is transarterial chemoembolization (TACE). Before sorafenib came into wide use, TACE had been pointlessly carried out repeatedly. It was in the early 2010s that the concept of TACE refractory was advocated. Two retrospective studies from Japan indicated that conversion from TACE to sorafenib the day after patients were deemed as TACE refractory improved overall survival compared with continued TACE, according to the definition by the Japan Society of Hepatology. Nowadays, phase 3 trials have shown clinical benefits of several novel molecular target agents. Compared with the era of sorafenib, sequential treatments with these molecular target agents have gradually prolonged patients’ survival and have become major strategies in patients with HCC. Taking these together, conversion from TACE to systemic therapies at the time of TACE refractory, compared with before, may have a greater impact on survival and may be considered deeper in the decisions-making process in patients with unresectable HCC who are candidate for TACE. Up-to-date information on the concept of TACE refractory is summarized in this review. We believe that the survival of patients with unresectable HCC without both macrovascular invasion and extrahepatic metastasis may be dramatically improved by optimal timing of TACE refractory and switching to systemic therapies.

Purpose: This study investigated the relationship between the number of days that hospital visits were postponed and changes in clinical parameters due to the spread of coronavirus disease 2019 (COVID-19), after the Japanese government declared a state of emergency in April 2020. Methods: Regarding the status of postponement of appointments, we analyzed the patients who had visited the Nihon University Hospital at Matsudo for more than 1 year for supportive periodontal therapy (SPT) and classified them into low-, moderate- and high-risk subgroups according to the periodontal risk assessment (PRA). Clinical parameters for periodontal disease such as probing depth (PD), full-mouth bleeding score (FMBS), full-mouth plaque score, periodontal inflamed surface area (PISA), and periodontal epithelial surface area (PESA) were analyzed in 2 periods, from October 2019 to March 2020 and after April 2020.Correlation coefficients between days of deferral and the degree of changes in clinical parameters were calculated. Results: The mean age of the 749 patients was 67.56±10.85 years, and 63.82% were female.Out of 749 patients, 33.24% deferred their SPT appointments after April 2020. The average total of postponement days was 109.49±88.84. The number of postponement days was positively correlated with changes in average PD (rs=0.474) and PESA (rs=0.443) in the high-risk subgroup of FMBS, and average PD (rs=0.293) and PESA (rs=0.253) in the highrisk subgroup of tooth number (TN). Patients belonging to the high-risk subgroups for both FMBS and TN had a positive correlation between postponement days and PISA (rs=0.56). Conclusions The findings, the spread of COVID-19 appears to have extended the visit interval for some SPT patients. Moreover, longer visit intervals were correlated with the worsening of some clinical parameters for SPT patients with high PRA.
