Vitamin B1 Deficiency Identified from Incidental Detection of Hyperlactatemia: A Case Report.

Introduction: Vitamin B1 deficiency poses a significant risk of impaired consciousness, with manifestations ranging from anorexia and fatigue to severe neurological and cardiovascular disturbances. Wernicke's encephalopathy, a neurological disorder stemming from vitamin B1 deficiency, presents as the triad of ophthalmoplegia, altered mental state, and cerebellar ataxia. However, these symptoms are not consistently present, complicating the diagnosis. In addition, subclinical vitamin B1 deficiency can progress unnoticed until severe complications arise. Studies indicate a high rate of undiagnosed cases, emphasizing the need for early detection and intervention. Case presentation: We present the case of a 65-year-old man in whom hyperlactatemia was incidentally detected, leading to the diagnosis of vitamin B1 deficiency. The patient, presenting with vertigo and vomiting, had been eating boxed lunches bought from convenience stores following the death of his wife 3 years earlier. Vertigo gradually improved with rest, but the persistence of hyperlactatemia prompted further investigation, revealing low vitamin B1 levels and high pyruvate levels. Treatment with dietary adjustments and supplements significantly improved his symptoms. Discussion: In this case, hyperlactatemia was found in a vertigo patient, revealing asymptomatic vitamin B1 deficiency. Elevated lactate is often linked with conditions like sepsis but can also stem from overlooked factors such as low vitamin B1 levels due to poor diet habits like consuming fried foods. Conclusion: This case highlights the importance of considering vitamin B1 deficiency in patients with unexplained hyperlactatemia, even in high-income countries. Early detection can prevent progression to the severe complications associated with Wernicke's encephalopathy. Proactive measurement of lactate levels in at-risk populations may facilitate early diagnosis and intervention, ultimately improving patient outcomes.

Effect of oxybutynin patch versus mirabegron on nocturia-related quality of life in female overactive bladder patients: A multicenter randomized trial.

OBJECTIVES: To investigate the effect of oxybutynin patch versus ß3-adrenoceptor agonist mirabegron on nocturia-related quality of life in female overactive bladder patients. METHODS: In the present study, female overactive bladder patients were enrolled. The patients were randomly allocated into two groups: the oxybutynin patch group and the mirabegron group. Each of the drugs was given for 8 weeks. The changes in the total Nocturia Quality of Life Questionnaire score were evaluated. Parameters on a frequency volume chart were also evaluated. RESULTS: In total, 100 patients (51 oxybutynin patch, 49 mirabegron) were treated with oxybutynin patch or mirabegron. The changes in the Nocturia Quality of Life Questionnaire score 4 weeks after administration were 3.8 ± 18.6 and 8.7 ± 13.1 with the oxybutynin patch group and the mirabegron group, respectively, which were significantly higher than those at the baseline. Furthermore, the changes in the Nocturia Quality of Life Questionnaire score 8 weeks after administration were 4.3 ± 16.5 and 7.7 ± 12.3, respectively. A statistical difference was seen only in the mirabegron group. Regarding the Nocturia Quality of Life Questionnaire subscores, oxybutynin patch and mirabegron significantly improved the Nocturia Quality of Life Questionnaire bother/concern subscore 4 and 8 weeks after administration, whereas the Nocturia Quality of Life Questionnaire sleep/energy subscore was not significantly improved in each period. Eight weeks after administration, 24-h frequency, 24-h urinary urgency and mean voided urine volume were improved in both groups statistically. CONCLUSIONS: The oxybutynin patch improves quality of life, focusing mainly on nocturia by improving the bother/concern subscores of the Nocturia Quality of Life Questionnaire in the short term.

National survey of international electives for global health in undergraduate medical education in Japan, 2011-2014.

Interest in global health in medical education is increasing in Western countries, whereas data from non-Western countries is scarce. Here, we conducted a nationwide study of international clinical electives at Japanese medical schools from 2011 to 2013. We constructed a 28-item cross-sectional survey in Japanese to investigate the rate and characteristics of both Japanese students going abroad and international students coming on exchange to Japan. The surveys were sent to the administrative offices of all 80 Japanese medical schools in each of the three years, through the Japan Medical Education Foundation. All 80 medical schools responded to the questionnaire (response rate, 100%). An average of 70 of the 80 medical universities provided exchange programs across the three years to allow students to travel abroad as part of the school curriculum and obtain academic credit. The schools provided support in the form of in- and outside-class preparatory programs, tuition fee exemptions and housing. The most popular destinations for Japanese students going abroad were Europe and North America, which may reflect the desire of Japanese students to acquire medical knowledge or experience through exposure to the English language. In contrast, the most common countries of origin of international exchange students coming to Japan were Asian countries such as South Korea, Thailand and Taiwan, with pediatrics being the most popular elective. Foreign exchange programs are becoming increasingly incorporated into the Japanese medical education curriculum and can help to strengthen international partnerships and collaborations.

Validity and reliability of the Japanese version of the CARE measure in a general medicine outpatient setting.

BACKGROUND: Empathy is an important attribute in medicine, influencing both the process and outcome of consultations. However, there are no validated tools available in Japan to gather patient feedback on physicians' empathy. The Consultation and Relational Empathy (CARE) Measure developed in the UK is widely used internationally. OBJECTIVES: To investigate the psychometric properties of a Japanese version of the CARE Measure. METHOD: Following two cycles of translation and back translation, the Japanese CARE Measure was completed by 317 patients in a primary medical care clinic in Japan. Tests of internal reliability and validity included Cronbach's alpha, item-total correlations and factor analysis. Predicted associations between CARE Measure score and other variables were assessed by Spearman's rho. RESULTS: Low numbers of missing values (8.2-9.8%) and 'not applicable' responses (0-1.3%) suggested high acceptability and face validity of the Japanese CARE Measure. Internal reliability was high (Cronbach's alpha 0.984) and was reduced by the removal of any of 10 items. High corrected item-total correlations (0.897-0.946) suggested homogeneity. Factor analysis showed a single solution with high item loadings (0.917-0.957). Construct validity was supported by a significant relationship (Spearman's rho 0.74, P < 0.001) with overall satisfaction with the consultation. CONCLUSION: The Japanese CARE Measure appears to be valid and reliable in a primary medical care setting. Further work is required to determine its ability to discriminate between doctors.

Limbic encephalitis associated with relapsing polychondritis responded to infliximab and maintained its condition without recurrence after discontinuation: a case report and review of the literature.

Central nervous system (CNS) manifestations are rare complications of relapsing polychondritis (RP). The majority of patients respond well to glucocorticoid therapy, but need to maintain it. Some patients are refractory to initial glucocorticoid therapy and to additional immunosuppressants, and end up with an outcome worse than at therapy initiation. The standardized therapeutic protocol for this condition has not been established. The effects of anti-tumor necrosis factor (TNF) -α agents have been reported recently. We experienced a patient with RP and limbic encephalitis who was refractory to initial high-dose glucocorticoid, but subsequently responded to infliximab and did not show deterioration of signs and symptoms after stopping therapy. We report this case together with a systematic literature review. This is the first case report of RP with CNS manifestations successfully treated by an anti-TNF-α agent without recurrence after discontinuation.

FRAMED: a framework facilitating insight problem solving.

Insight has been studied as an element of problem solving in the field of cognitive psychology and may play an important role in clinical reasoning. We propose a new strategy based on theories that promote insight that may help generate further diagnostic hypotheses by reviewing the interpretation of a case and an individual's list of differential diagnoses from multiple perspectives: formation (F), re-encoding (R), analogy (A), modification (M), elaboration (E), and deliberation (D) (FRAMED). The FRAMED strategy may help clinicians overcome misinterpretations and cognitive bias by systematically reflecting on previous clinical reasoning processes from multiple perspectives.

Selective IgA deficiency mimicking Churg-Strauss syndrome and hypereosinophilic syndrome: a case report.

Selective IgA deficiency (SIgAD) is the most common type of primary immunoglobulin deficiency. Most individuals with SIgAD are asymptomatic. However, some patients are associated with allergic and autoimmune disease. SIgAD is included in the list of differential diagnoses of eosinophilia. We experienced a patient who initially presented with abdominal pain and eosinophilia. A >1-year follow-up revealed SIgAD, and we had difficulty differentiating it from Churg-Strauss syndrome (CSS) or hypereosinophilic syndrome (HES). A 66-year-old Japanese male presented with a history of recurrent abdominal pain. A diagnostic work-up revealed eosinophilia, eosinophilic gastritis, eosinophilic pneumonia, and SIgAD over 1 year of clinical observation. He also suffered from asthma and sinusitis. Anti-neutrophil cytoplasmic antibody was negative and vasculitis was not detected in the obtained tissue specimens of stomach, lung, nose and skin. The patient showed no evidence of drug ingestion, parasitic infections, or malignant neoplasms. Although we cannot rule out prevasculitic CSS and idiopathic HES, the whole clinical picture in this patient can be explained most consistently by SIgAD.

A Case of Primary Intestinal Lymphangiectasia Successfully Controlled with a Denver Peritoneovenous Shunt for Refractory Ascites.

A 53-year-old man presented with abdominal symptoms and a fever for 6 months and ascites and lower body edema for 2 months before visiting our clinic. Heart failure, renal failure, inferior vena cava or portal vein obstruction, cirrhosis, and malignancy were suspected, but none were present. We also suspected protein-leakage gastroenteropathy based on the elevated alpha-1 antitrypsin clearance (224 mL/day). Based on the double-balloon endoscopy findings, we diagnosed the patient with primary intestinal lymphangiectasia. Since the patient's ascites were not satisfactorily controlled medically, a Denver peritoneovenous shunt was placed. As a result, the ascites volume was successfully controlled over an extended period.

Newspaper Campaign to Promote Deceased Organ Donation: Who Can Appeal to the General Japanese Population?

BACKGROUND: Various interventions are reportedly effective in promoting organ donor registration. However, the identity of those who best serve as presenters to appeal to the general public is not known. METHODS: A campaign for organ donor registration was conducted through a local newspaper advertisement in Japan. The advertisement appeared in 439,733 copies of the newspaper on January 9, 2021. In addition to the main message, 6 different presenters with photos of their faces and quick response codes were listed in the advertisement, namely a urologist, transplant physician, nephrologist, dialysis physician, ophthalmologist, and kidney transplant recipient who was a nephrologist himself (ie, a recipient and nephrologist). Newspaper readers watched each video about deceased organ donation via the quick response codes, and the number of video views acquired 30 days after the appearance was the main outcome, which was assessed using YouTube analytics. The proportions (95% CI) of people who watched each video among 439,733 newspaper readers were compared among the 6 presenters. RESULTS: The analyzed videos were viewed 262 times. The video produced by the recipient and nephrologist had the highest number of views among the 6 presenters (proportion: 0.019% [95% CI, 0.015-0.023]), followed by the one produced by the dialysis physician (0.011% [95% CI, 0.008-0.014]), the nephrologist (0.010% [95% CI, 0.007-0.014]), the urologist (0.008% [95% CI, 0.006-0.012]), the transplant physician (0.006% [95% CI, 0.004-0.009]), and the ophthalmologist (0.005% [95% CI, 0.004-0.008]). CONCLUSIONS: The appeal by the recipient and the nephrologist reached the highest proportion of people who watched the video about deceased organ donation in Japan.

Association between administration or recommendation of the human papillomavirus vaccine and primary care physicians' knowledge about vaccination during proactive recommendation suspension: a nationwide cross-sectional study in Japan.

OBJECTIVE: The Japanese government suspended the proactive recommendation of the human papillomavirus vaccine (HPVv) in 2013, and the vaccination rate of HPVv declined to <1% during 2014-2015. Previous studies have shown that the recommendation by a physician affects a recipient's decision to receive a vaccine, and physicians' accurate knowledge about vaccination is important to increase vaccine administration. This study aimed to evaluate the association between physicians' knowledge of vaccination and the administration or recommendation of HPVv by primary care physicians (PCPs) in the absence of proactive recommendations from the Japanese government. DESIGN: Cross-sectional study analysed data obtained through a web-based, self-administered questionnaire survey. SETTING: The questionnaire was distributed to Japan Primary Care Association (JPCA) members. PARTICIPANTS: JPCA members who were physicians and on the official JPCA mailing list (n=5395) were included. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary and secondary outcomes were the administration and recommendation of HPVv, respectively, by PCPs. The association between PCPs' knowledge regarding vaccination and each outcome was determined based on their background and vaccination quiz scores and a logistic regression analysis to estimate the adjusted ORs (AORs). RESULTS: We received responses from 1084 PCPs and included 981 of them in the analysis. PCPs with a higher score on the vaccination quiz were significantly more likely to administer the HPVv for routine and voluntary vaccination (AOR 2.28, 95% CI 1.58 to 3.28; AOR 2.71, 95% CI 1.81 to 4.04, respectively) and recommend the HPVv for routine and voluntary vaccination than PCPs with a lower score (AOR 2.17, 95% CI 1.62 to 2.92; AOR 1.88, 95% CI 1.32 to 2.67, respectively). CONCLUSIONS: These results suggest that providing accurate knowledge regarding vaccination to PCPs may improve their administration and recommendation of HPVv, even in the absence of active government recommendations.

Factors associated between behavior of administrating or recommending mumps vaccine and primary care physicians' knowledge about vaccination: A nationwide cross-sectional study in Japan.

BACKGROUND: In Japan, the mumps-containing vaccine was withdrawn from routine vaccination in 1993, and it became a voluntary vaccination. This study aimed to evaluate the association between the physicians' knowledge about vaccinations and the administration or recommendation of the mumps vaccine. METHODS: We conducted a nationwide cross-sectional study targeting primary care physicians (PCPs) in Japan. We used a web-based self-administered questionnaire by Preventive Medicine and Health Promotion Committee Vaccine Team, the Japan Primary Care Association (JPCA), from March to June in 2019. The outcome of the study was the association between PCPs' knowledge about vaccine and the administration or recommendation of mumps vaccine. We obtained the information on background, subsidies of mumps vaccination for children from the local government, and vaccination quiz scores. We performed logistic regression analysis to estimate the odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Among 10,470 PCPs in JPCA, 5075 were excluded. We received responses from 1084 PCPs (20.1%) and enrolled 981 participants in the analysis. PCPs with a higher score on the vaccination quizzes were significantly more likely to administrate the mumps vaccine for adults (adjusted odds ratio [AOR] 1.93, 95% CI 1.45-2.59, p < 0.001) and recommend mumps vaccine to adults than PCPs with a lower score (AOR 1.78, 95% CI 1.33-2.40, p < 0.001). CONCLUSIONS: We revealed an association between the administration or recommendation of mumps vaccine and PCPs' better vaccination knowledge.

Association between history of HBV vaccine response and anti-SARS-CoV-2 spike antibody response to the BioNTech/Pfizer's BNT162b2 mRNA SARS-CoV-2 vaccine among healthcare workers in Japan: A prospective observational study.

INTRODUCTION: Inadequate vaccine response is a common concern among healthcare workers at the frontlines of the COVID-19 pandemic. We aimed to investigate if healthcare workers with history of weak immune response to HBV vaccination are more likely to have weak responses against the BioNTech/Pfizer's BNT162b2 mRNA SARS-CoV-2 vaccine. METHODS: We prospectively tested 954 healthcare workers for the Anti-SARS-CoV-2 spike (S) protein antibody titers prior to the first and second BNT162b2 vaccination doses and after four weeks after the second dose using Roche's Elecsys® assay. We calculated the percentage of patients who seroconverted after the first and second doses. We estimated the relative risk of non-seroconversion after the first BNT162b2 vaccine (defined as anti-SARS-CoV-2-S titer <15 U/mL) among HBV vaccine non-responders (HBs-Ab titer <10 mIU/mL) and weak responders (≥10 and <100 mIU/mL) compared to normal responders (≥100 mIU/mL). RESULTS: Among 954 healthcare workers recruited between March 9 and March 24, 2021 at Osaka Medical and Pharmaceutical University, weak and normal HBV vaccine responders had comparable S-protein titers after the first BNT162b2 dose (51.4 [95% confidence interval 25.2-137.0] versus 59.7 [29.8-138.0] U/mL, respectively). HBV vaccine non-responders were more likely than normal responders to not seroconvert after a single dose (age and sex-adjusted relative risk 1.85 95% confidence interval [1.10-3.13]) although nearly all participants seroconverted after the second dose. After limiting the analysis to 382 patients with baseline comorbidity data, the comorbidity-adjusted relative risk of non-seroconversion among HBV vaccine non-responders to normal responders was 1.32 (95% confidence interval [0.59-2.98]). DISCUSSION: Long term follow-up studies are needed to understand if protective immunity against SARS-CoV-2 wanes faster among those with history of HBV vaccine non-response and when booster doses are warranted for these healthcare workers.

A national survey to explore the willingness of Japanese standardized patients to participate in teaching physical examination skills to undergraduate medical students.

BACKGROUND: Standardized patients (SPs) are an increasingly prevalent resource in medical education and evaluation. There is a variety of clinical skills training programs including courses designed to teach and assess communication skills as well as physical examination (PE) skills. In Japan, SPs have contributed enormously to help medical students improve their communication skills. However, there are few SPs who participate in physical examination training and the use of SPs for physical examination is rarely considered as a useful educational resource. PURPOSE: The purpose is to explore SPs' perceptions about participating in PE training. METHOD: A 27-item questionnaire was used to survey 532 SPs in Japan. RESULT: The response rate was 62% (n = 332). The ratio of females to males was 4:1. SPs perceived PE training using SPs was effective in teaching students physical examination. Eighty percent of SPs were willing to have PE of head, arms, and legs. Twenty-five percent were willing to have PE on their chest, back, and abdomen. Willingness varied by gender and age. CONCLUSION: SPs perceived that including SPs in physical examination was valuable. Males or people over 50 years old are more willing to participate than females or people under 50. Reluctance to participate in PE may decrease through experience or improved knowledge of PE training and by beginning with examination of head, neck, and legs, then gradually moving to chest, back, and abdomen.

Key diagnostic characteristics of fever of unknown origin in Japanese patients: a prospective multicentre study.

OBJECTIVE: To identify the key diagnostic features and causes of fever of unknown origin (FUO) in Japanese patients. DESIGN: Multicentre prospective study. SETTING: Sixteen hospitals affiliated with the Japanese Society of Hospital General Medicine, covering the East and West regions of Japan. PARTICIPANTS: Patient aged ≥20 years diagnosed with classic FUO (axillary temperature≥38.0°C at least twice within a 3-week period, cause unknown after three outpatient visits or 3 days of hospitalisation). A total of 141 cases met the criteria and were recruited from January 2016 to December 2017. INTERVENTION: Japanese standard diagnostic examinations. OUTCOME MEASURES: Data collected include usual biochemical blood tests, inflammatory markers (erythrocyte sedimentation rate (ESR), C reactive (CRP) protein level, procalcitonin level), imaging results, autopsy findings (if performed) and final diagnosis. RESULTS: The most frequent age group was 65-79 years old (mean: 58.6±9.1 years). The most frequent cause of FUO was non-infectious inflammatory disease. After a 6-month follow-up period, 21.3% of cases remained undiagnosed. The types of diseases causing FUO were significantly correlated with age and prognosis. Between patients with and without a final diagnosis, there was no difference in CRP level between patients with and without a final diagnosis (p=0.121). A significant difference in diagnosis of a causative disease was found between patients who did or did not receive an ESR test (p=0.041). Of the 35 patients with an abnormal ESR value, 28 (80%) had causative disease identified. CONCLUSIONS: Age may be a key factor in the differential diagnosis of FUO; the ESR test may be of value in the FUO evaluation process. These results may provide clinicians with insight into the management of FUO to allow adequate treatment according to the cause of the disease.

What sort of medical care is ideal? Differences in thoughts on medical care among residents of urban and rural/remote Japanese communities.

Studies of aspirational ideals of medical care generally focus on patients rather than on ordinary people receiving or not receiving medications at the time of interview. The literature has not accurately conveyed the distinct ideals in individual communities or undertaken inter-regional comparisons. This current qualitative study focused on ideal medical care as perceived by residents of distinct Japanese communities in their everyday lives. Between December 2011 and November 2012, one-on-one and group-based semi-structured interviews were conducted with 105 individuals, each of whom had continuously lived for 20 years or more in one of the four types of communities classified as either 'metropolitan area', 'provincial city', 'mountain/fishing village' or 'remote island' in Japan. Interviews were transcribed from digital audio recordings and then analysed (in tandem with non-verbal data including participants' appearances, attitudes and interview atmospheres) using constructivist grounded theory, in which we could get the voice and mind of the participant concerning ideal medical care. The common themes observed among the four community types included 'peace of mind because of the availability of medical care' and 'trust in medical professionals'. Themes that were characteristic of urban communities were the tendency to focus on the content of medical care, including 'high-level medical care', 'elimination of unnecessary medical care' and 'faster, cheaper medical care', whereas those that were characteristic of rural communities were the tendency to focus on lifestyle-oriented medical care such as 'support for local lifestyles', 'locally appropriate standards of medical care' and 'being free from dependence on medical care'. The sense of ideal medical care in urban communities tended to centre around the satisfaction with the content of medical care, whereas that in rural communities tended to centre around the ability to lead a secure life. By considering medical care from the geographical point of view, we found out the significant relationship between communities and perceptions of medical care ideals.

[Renal cell carcinoma in acquired cystic disease of the kidney manifested by spontaneous renal rupture].

A 67-year-old male had been maintained on hemodialysis for 13 years because of chronic renal failure secondary to diabetes mellitus. The patient was referred to our hospital with sudden right flank pain. Computed tomography revealed multiple cysts in both kidneys and a right massive perirenal hematoma. Although there was no definite evidence of a renal tumor, a right nephretomy was performed. Histological study revealed acquired cystic disease of the kidney (ACDK) with a hematoma containing papillary renal cell carcinoma. He has been free of recurrence for 2 months. To our knowledge, this case is the fourth report of renal cell carcinoma in ACDK manifested by spontaneous rupture in the Japanese literature.
