RESUMO
Vitamin C deficiency, also known as scurvy, causes abnormalities in connective tissues and varied symptoms. We describe a patient with putaminal hemorrhage, a very rare presentation of scurvy. A 39-year-old man presented with weakness in the left arm and left leg. Right putaminal hemorrhage was initially diagnosed, and he underwent evacuation of the intracerebral hemorrhage. Scurvy was suspected when repeated physical examinations revealed a bleeding tendency and multiple untreated dental caries, missing teeth, and gingivitis. A diagnosis of scurvy was further supported by the patient's history of smoking, alcohol use disorder, poor diet, and low plasma vitamin C concentration. After receiving oral nutritional supplementation including vitamin C, the bleeding tendency quickly improved. This case highlights the importance of including scurvy in a differential diagnosis for patients with bleeding tendencies, especially those with a poor diet or unknown dietary history. Empirical administration of vitamin C is a reasonable treatment.
RESUMO
Background Shared decision-making is important for deciding whether to perform surgery, especially high-risk surgery, or end-of-life care in cases of serious complications after the surgery. In shared decision-making, surgeons should be aware of patients' values. Therefore, advance care planning (ACP) before the surgery is important. In Japan, the feasibility of ACP, particularly preoperative nurse-led ACP, is yet to be evaluated. Methodology This retrospective, single-center, descriptive study included all adult candidates for open-heart or thoracic aortic surgery and transcutaneous aortic valve implantation (TAVI) referred by their surgeon for a nurse-led preoperative ACP between April 1, 2020 and December 31, 2021. The nurse conducted semi-structured interviews with patients regarding goals of care, unacceptable conditions, undesired procedures, advance directives, and their surrogates and documented them. The content of these interviews and their influence on decision-making were retrospectively investigated. Results Sixty-four patients (median age, 82 years; Society of Thoracic Surgeons (STS) score, 7.9; EuroSCORE II, 4.2; JapanSCORE, 7.0) were included (open-heart or thoracic aortic surgery 24, TAVI 40). Among them, 63 (98.4%), 56 (87.5%), and 13 (20.3%) patients articulated their goals of care, unacceptable conditions, and undesired procedures. Only one (1.6%) had a written advance directive. Although all of the patients could designated their surrogate, only 11 (17.2%) had shared their values disclosed in the pre-procedure ACP communication with their surrogates. Two patients who planned to undergo open-heart surgery disclosed their wish not to undergo the surgery only to the nurses but could not tell their surgeon; thereafter, the surgery was canceled. Three patients died after the procedure; however, the patients' value disclosed in ACP was not used for the end-of-life decision. Conclusion Nurse-led ACP can be implemented before high-risk cardiac procedures. It may have an impact on the decision-making of surgery although the ACP content may not be utilized for the end-of-life discussion after the procedures between surgeons and the family member.
RESUMO
BACKGROUND: The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II is a predictive model for in-hospital mortality after cardiac surgery. Although it has good performance among the general population undergoing cardiac surgery, it has not been validated among dialysis patients, who have a higher rate of mortality after cardiac surgery. This study aimed to evaluate the performance of the model in predicting in-hospital mortality in maintenance dialysis patients undergoing cardiac surgery. METHODS: This retrospective, single-center study included adult patients on maintenance dialysis who underwent open cardiac surgery at our institution. Calibration performance of EuroSCORE II for in-hospital death was determined based on the comparison between expected and observed mortalities for low- (EuroSCORE II <4â¯%), intermediate- (4-8â¯%), and high-risk (>8â¯%) groups. The area under receiver operating characteristic curve (AUROC) was investigated to determine the model's discrimination performance. RESULTS: A total of 163 patients (male, 73.6â¯%; median age, 70â¯years; median dialysis vintage, 9â¯years; median EuroSCORE II, 3.3â¯%) were included. The mortality rate was 9.2â¯%. The observed mortality rates (vs. mean expected mortality) rates were 2.1â¯% (vs. 2.4â¯%), 7.5â¯% (vs. 5.5â¯%), and 34.5â¯% (vs. 21.1â¯%) in the low-, intermediate-, and high-risk groups, respectively. Its AUROC was 0.825 (95â¯% confidence interval, 0.711-0.940). CONCLUSIONS: Although EuroSCORE II model adequately estimated in-hospital mortality in the low-and intermediate-risk groups (EuroSCORE II <8â¯%), it underestimated in-hospital mortality in the high-risk group (EuroSCORE II >8â¯%) among maintenance dialysis patients. The discrimination performance of the model for in-hospital death was good among maintenance dialysis patients.
RESUMO
BACKGROUND: Current guidelines for non-small-cell lung cancer (NSCLC) recommend that each tyrosine kinase inhibitor (TKI) is indicated even for driver mutation-positive patients with a poor performance status (PS). In previous studies, most patients had a PS of 2-3, but those with a PS of 4 were very few. Therefore, the efficacy of TKIs in patients with NSCLC with a PS of 4 remains unclear. CASE PRESENTATION: We retrospectively reviewed the clinical records of four patients with NSCLC with PS 4 treated with TKIs: an 89-year-old Japanese woman (Case 1), a 80-year-old Japanese woman (Case 2), an 50-year-old Japanese man (Case 3), and a 81-year-old Japanese woman (Case 4). Genetic alterations were epidermal growth factor receptor (EGFR), MET exon 14 skipping, BRAFV600E, and ROS1 proto-oncogene receptor tyrosine kinase (ROS1). One case with ROS1 fusion showed a significant response with the recovery of PS. However, in the remaining three cases (i.e., EGFR, MET exon 14 skipping, and BRAFV600E mutations), patients died despite the administration of TKIs. These three patients had to be hospitalized at the end of their life to receive treatment. CONCLUSIONS: This is the first case series to summarize the efficacy of TKIs in patients with NSCLC with a PS of 4. Additionally, this case series poses a question concerning the indication of TKIs for older patients with a PS of 4.

Dabrafenib plus trametinib is active against metastatic lung cancer with the BRAF V600E mutation. However, the feasibility of dabrafenib plus trametinib for patients with a poor performance status (PS) has not been reported. We report the case of an 80-year-old woman was diagnosed with metastatic large-cell lung carcinoma. Her general statuses worsened due to cancer, resulting in a PS of 4. Genotype testing revealed a BRAF V600E mutation. The patient received dabrafenib plus trametinib without significant adverse effects. This report is the first to describe dabrafenib plus trametinib administration for large-cell lung carcinoma in a patient with a poor PS.
RESUMO
BACKGROUND: The joint committee of the Japanese Society of Intensive Care Medicine/Japanese Respiratory Society/Japanese Society of Respiratory Care Medicine on ARDS Clinical Practice Guideline has created and released the ARDS Clinical Practice Guideline 2021. METHODS: The 2016 edition of the Clinical Practice Guideline covered clinical questions (CQs) that targeted only adults, but the present guideline includes 15 CQs for children in addition to 46 CQs for adults. As with the previous edition, we used a systematic review method with the Grading of Recommendations Assessment Development and Evaluation (GRADE) system as well as a degree of recommendation determination method. We also conducted systematic reviews that used meta-analyses of diagnostic accuracy and network meta-analyses as a new method. RESULTS: Recommendations for adult patients with ARDS are described: we suggest against using serum C-reactive protein and procalcitonin levels to identify bacterial pneumonia as the underlying disease (GRADE 2D); we recommend limiting tidal volume to 4-8 mL/kg for mechanical ventilation (GRADE 1D); we recommend against managements targeting an excessively low SpO2 (PaO2) (GRADE 2D); we suggest against using transpulmonary pressure as a routine basis in positive end-expiratory pressure settings (GRADE 2B); we suggest implementing extracorporeal membrane oxygenation for those with severe ARDS (GRADE 2B); we suggest against using high-dose steroids (GRADE 2C); and we recommend using low-dose steroids (GRADE 1B). The recommendations for pediatric patients with ARDS are as follows: we suggest against using non-invasive respiratory support (non-invasive positive pressure ventilation/high-flow nasal cannula oxygen therapy) (GRADE 2D), we suggest placing pediatric patients with moderate ARDS in the prone position (GRADE 2D), we suggest against routinely implementing NO inhalation therapy (GRADE 2C), and we suggest against implementing daily sedation interruption for pediatric patients with respiratory failure (GRADE 2D). CONCLUSIONS: This article is a translated summary of the full version of the ARDS Clinical Practice Guideline 2021 published in Japanese (URL: https://www.jsicm.org/publication/guideline.html ). The original text, which was written for Japanese healthcare professionals, may include different perspectives from healthcare professionals of other countries.
RESUMO
The effects of lower tidal volume ventilation (LTV) were controversial for patients with acute respiratory distress syndrome (ARDS). This systematic review and meta-analysis aimed to evaluate the use of LTV strategy in patients with ARDS. We performed a literature search on MEDLINE, CENTRAL, EMBASE, CINAHL, "Igaku-Chuo-Zasshi", clinical trial registration sites, and the reference of recent guidelines. We included randomized controlled trials (RCTs) to compare the LTV strategy with the higher tidal volume ventilation (HTV) strategy in patients with ARDS. Two authors independently evaluated the eligibility of studies and extracted the data. The primary outcomes were 28-day mortality. We used the GRADE methodology to assess the certainty of evidence. Among the 19,864 records screened, 13 RCTs that recruited 1874 patients were included in our meta-analysis. When comparing LTV (4-8 ml/kg) versus HTV (> 8 ml/kg), the pooled risk ratio for 28-day mortality was 0.79 (11 studies, 95% confidence interval [CI] 0.66-0.94, I2 = 43%, n = 1795, moderate certainty of evidence). Subgroup-analysis by combined high positive end-expiratory pressure with LTV showed interaction (P = 0.01). Our study indicated that ventilation with LTV was associated with reduced risk of mortality in patients with ARDS when compared with HTV. Trial registration: UMIN-CTR (UMIN000041071).

BACKGROUND Osimertinib is an oral third-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) approved as first-line therapy for advanced non-small cell lung cancer (NSCLC) with positive EGFR mutation. Rashes, nail toxicity, and diarrhea are common adverse events. Hematological adverse effects, including anemia, thrombocytopenia, and lymphocytopenia, have been reported. However, erythrocytosis has not been reported as an adverse event. To the best of our knowledge, we report the first case of acute lower extremity thrombosis presumably caused by osimertinib-induced erythrocytosis. CASE REPORT A 70-year-old man with epidermal EGFR-mutant advanced NSCLC presented with acute left sural pain. The patient's left foot was cold, and peripheral arterial Doppler signals were absent. He had developed erythrocytosis of unknown etiology during osimertinib therapy. Hemoglobin (Hb) and hematocrit were 22.6 g/dL and 62.5%, respectively. Contrast-enhanced computed tomography showed thrombotic occlusion of the popliteal artery. Other than erythrocytosis, there was no possible cause of arterial thrombosis. Osimertinib was discontinued immediately because the NSCLC started to resist treatment and was presumed to be the cause of erythrocytosis. He received endovascular treatment (EVT). Following serial EVT and debridement, his fourth toe was amputated for necrosis. Erythrocytosis persisted 8 months during osimertinib therapy. Hb levels decreased to 15.4 mg/dL due to blood loss complicated with catheter thrombectomy and remained normal for 20 months after osimertinib discontinuation. The patient died of cancer progression. CONCLUSIONS This case suggests the erythrocytosis was possibly caused by osimertinib. We may need to monitor Hb levels during osimertinib therapy and be alert to thrombosis once Hb starts to rise.

BACKGROUND: Diagnostic errors or delays can cause serious consequences for patient safety, especially in the emergency department. Anchoring bias is one of the major factors leading to diagnostic error. During the coronavirus disease 2019 (COVID-19) pandemic, the high probability of COVID-19 in febrile patients could be a major cause of anchoring bias leading to diagnostic error. In addition, certain evaluations such as auscultation are difficult to perform on a casual basis due to the increased risk of contact infection, which lead to inadequate assessment of the patients with valvular disease. Acute mitral regurgitation (MR) could be a fatal disease in the emergency department, especially if there is a diagnostic error or delay in diagnosis. It is often reported that diagnosis can be difficult even though there is no treatment other than emergent surgery. The diagnosis of acute MR has become more difficult because coronavirus disease 2019 (COVID-19) pandemic could affect our daily practice especially in febrile patients. We report a case of a diagnostic delay of a febrile patient because of anchoring bias during the COVID-19 pandemic. CASE PRESENTATION: A 45-year-old man presented to the emergency department complaining of acute dyspnea and fever. Based on vital signs and computed tomography of the chest, acute pneumonia due to COVID-19 was suspected. Auscultation was avoided because of facility rule based on concern of contact infection. After admission to the intensive care unit, Doppler echocardiography revealed acute mitral regurgitation, and transesophageal echocardiography revealed mitral valve tendon rupture. After confirming the negative result for the polymerase chain reaction of severe acute respiratory syndrome coronavirus 2, mitral valvuloplasty was performed on the third day after admission. The patient was discharged 14 days after admission without complications. CONCLUSIONS: In COVID-19 pandemic, anchoring bias suspecting COVID-19 among febrile patients becomes a strong heuristic factor. A thorough history and physical examination is still important in febrile patients presenting with dyspnea to ensure the correct diagnosis of acute mitral regurgitation.
RESUMO
BACKGROUND: Code status discussion is associated with a decrease in invasive procedures among terminally ill cancer patients. We investigated the association between code status discussion on admission and incidence of invasive procedures, cardiopulmonary resuscitation (CPR), and opioid use among inpatients with advanced stages of cancer and noncancer diseases. METHODS: We performed a retrospective cohort study in a single center, Ito Municipal Hospital, Japan. Participants were patients who were admitted to the Department of Internal Medicine between October 1, 2013 and August 30, 2015, with advanced-stage cancer and noncancer. We collected demographic data and inquired the presence or absence of code status discussion within 24 hours of admission and whether invasive procedures, including central venous catheter placement, intubation with mechanical ventilation, and CPR for cardiac arrest, and opioid treatment were performed. We investigated the factors associated with CPR events by using multivariate logistic regression analysis. RESULTS: Among the total 232 patients, code status was discussed with 115 patients on admission, of which 114 (99.1%) patients had do-not-resuscitate (DNR) orders. The code status was not discussed with the remaining 117 patients on admission, of which 69 (59%) patients had subsequent code status discussion with resultant DNR orders. Code status discussion on admission decreased the incidence of central venous catheter placement, intubation with mechanical ventilation, and CPR in both cancer and noncancer patients. It tended to increase the rate of opioid use. Code status discussion on admission was the only factor associated with the decreased use of CPR (P<0.001, odds ratio =0.03, 95% CI =0.004-0.21), which was found by using multivariate logistic regression analysis. CONCLUSION: Code status discussion on admission is associated with a decrease in invasive procedures and CPR in cancer and noncancer patients. Physicians should be educated about code status discussion to improve end-of-life care.
RESUMO
BACKGROUND: Cumulative sum (CUSUM) analysis can be used to continuously monitor the performance of an individual or process and detect deviations from a preset or standard level of achievement. However, no previous study has evaluated the utility of CUSUM analysis in facilitating timely environmental assessment and interventions to improve performance of linear-probe endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). The aim of this study was to evaluate the usefulness of combined CUSUM and chronological environmental analysis as a tool to improve the learning environment for EBUS-TBNA trainees. METHODS: This study was an observational chart review. To determine if performance was acceptable, CUSUM analysis was used to track procedural outcomes of trainees in EBUS-TBNA. To investigate chronological changes in the learning environment, multivariate logistic regression analysis was used to compare several indices before and after time points when significant changes occurred in proficiency. RESULTS: Presence of an additional attending bronchoscopist was inversely associated with nonproficiency (odds ratio, 0.117; 95% confidence interval, 0-0.749; P = 0.019). Other factors, including presence of an on-site cytopathologist and dose of sedatives used, were not significantly associated with duration of nonproficiency. CONCLUSIONS: Combined CUSUM and chronological environmental analysis may be useful in hastening interventions that improve performance of EBUS-TBNA.

BACKGROUND: Japan has no official guidelines for do-not-resuscitate (DNR) orders. Therefore, we investigated the effect of DNR orders on physician decision making in relation to performing noncardiopulmonary resuscitation (CPR) and CPR procedures. METHODS: A case-scenario-based questionnaire that included a case of advanced cancer, a case of advanced dementia, and a case of nonadvanced heart failure was administered to physicians. The questions determined whether physicians would perform different non-CPR procedures and CPR procedures in the presence or absence of DNR orders. The number of non-CPR procedures each physician would perform and the number of physicians who would perform each non-CPR and CPR procedure in the absence and presence of DNR ocrders were compared. Physicians from three Japanese municipal acute care hospitals participated. RESULTS: We analyzed 111 of 161 (69%) questionnaires. Physicians would perform significantly fewer non-CPR procedures in the presence of DNR orders than in the absence of DNR orders for all three case scenarios (median [interquartile range] percentages: Case 1: 72% [45%-90%] vs 100% [90%-100%]; Case 2: 55% [36%-72%] vs 91% [63%-100%]; Case 3: 78% [55%-88%] vs 100% [88%-100%]). Fewer physicians would perform non-CPR and CPR procedures in the presence of DNR orders than in the absence of DNR orders. However, considerable numbers of physicians would perform electric shock treatment for ventricular fibrillation in the presence of DNR orders (Case 1: 26%; Case 2: 16%; Case 3: 20%). CONCLUSION: DNR orders affect physician decision making about performing non-CPR procedures. Although some physicians would perform CPR for ventricular fibrillation in the presence of DNR orders, others would not. Therefore, a consensus definition for DNR orders should be developed in Japan, otherwise DNR orders may cause harm.
RESUMO
Symptomatic giant extracranial internal carotid artery (ICA) aneurysm is a rare and surgically intractable disease. Several authors have described successful treatments for extracranial ICA aneurysm. None, however, have described a perioperative evaluation of cerebral perfusion or a postoperative complication of cerebral hyperperfusion syndrome (CHS). We present a rare case of CHS after endovascular covered stent grafting for a giant extracranial ICA aneurysm. The CHS was successfully managed on the basis of hemodynamic monitoring. CHS can appear after endovascular reconstruction of an extracranial ICA aneurysm, and perioperative repeated evaluation of cerebral perfusion allows safe and effective management of CHS.
