RESUMO
Background: Multidisciplinary team meetings (MDTMs) are crucial in the ICU. However, daily rounds may not address all sensitive issues due to time constraints and the complexity of cases. This study aimed to describe detailed information and characteristics of ad hoc MDTMs in the ICU. Methods: This single-center, retrospective study analyzed adult emergency ICU admissions at Okayama University Hospital from 1 January 2019 to 31 December 2023. During this period, weekly regular multidisciplinary team ICU rounds were introduced in June 2020, and regular weekday morning MDTMs began in April 2022. A multiple logistic regression analysis was applied to determine the impact of these changes on the frequency of ad hoc MDTMs, adjusting for variables including annual changes. Results: The study analyzed 2487 adult EICU patients, with a median age of 66, and 63.3% of them male. MDTMs were held for 168 patients (6.8%), typically those with severe conditions, including higher COVID-19 prevalence and APACHE II scores, and longer ICU stays. Despite a constant total number of MDTMs, the likelihood of conducting ad hoc MDTMs increased annually (adjusted OR 1.19; 95% CI, 1.04-1.35). Of the 329 MDTMs conducted for these patients, 59.0% addressed end-of-life care, involving an average of 11 participants, mainly nurses and emergency and critical-care physicians. Conclusions: Changes in ICU round and meeting structures might be associated with a higher frequency of conducting ad hoc MDTMs, highlighting their evolving role and importance in patient care management.
RESUMO
This study investigated the correlation between oxidative stress and blood amino acids associated with nitric oxide metabolism in adult patients with coronavirus disease (COVID-19) pneumonia. Clinical data and serum samples were prospectively collected from 100 adult patients hospitalized for COVID-19 between July 2020 and August 2021. Patients with COVID-19 were categorized into three groups for analysis based on lung infiltrates, oxygen inhalation upon admission, and the initiation of oxygen therapy after admission. Blood data, oxidative stress-related biomarkers, and serum amino acid levels upon admission were compared in these groups. Patients with lung infiltrations requiring oxygen therapy upon admission or starting oxygen post-admission exhibited higher serum levels of hydroperoxides and lower levels of citrulline compared to the control group. No remarkable differences were observed in nitrite/nitrate, asymmetric dimethylarginine, and arginine levels. Serum citrulline levels correlated significantly with serum lactate dehydrogenase and C-reactive protein levels. A significant negative correlation was found between serum levels of citrulline and hydroperoxides. Levels of hydroperoxides decreased, and citrulline levels increased during the recovery period compared to admission. Patients with COVID-19 with extensive pneumonia or poor oxygenation showed increased oxidative stress and reduced citrulline levels in the blood compared to those with fewer pulmonary complications. These findings suggest that combined oxidative stress and abnormal citrulline metabolism may play a role in the pathogenesis of COVID-19 pneumonia.

Neuroleptic malignant syndrome (NMS) is a rare but life-threatening medical condition often characterized by altered consciousness and clinical features resembling seizures. This case report presents a unique and successful diagnosis of NMS in an unconscious patient with an unknown medical history. We demonstrate the potential utility of amplitude-integrated electroencephalography (aEEG) as a valuable tool for the differential diagnosis of seizure-like medical conditions, including NMS. The application of aEEG allowed for early diagnosis and prompt initiation of appropriate treatment, potentially contributing to improved patient outcomes.
RESUMO
Background: The clinical impact of signs of life (SOLs) in traumatic cardiac arrest (TCA) remains to be elucidated. The aim of this study was to examine the association between SOLs and survival/neurological outcomes in TCA patients. Methods: Retrospective data from the Japan Trauma Data Bank (2019-2021) was reviewed. TCA patients were assigned to one of two study groups based on the presence or absence of SOLs and compared. SOLs were defined as having at least one of following criteria: pulseless electrical activity >40 beats per minute, gasping, positive light reflex, or extremity/eye movement at hospital arrival. The primary outcome was survival at hospital discharge. The secondary outcome was favorable neurological status (Glasgow Outcome Scale score of 4 or 5) at hospital discharge. Results: A total of 1,981 patients (114 with SOLs and 1,867 without SOLs) were included. Characteristics of patients were as follows: age (median age 60.0 years old [interquartile range: 41-80] years vs. 55.4 [38-75] years), gender (male: 76/114 (66.7%) vs. 1,207/1,867 (65.0%), blunt trauma (90/111 [81.1%] vs. 1,559/1,844 [84.5%]), Injury Severity Score (29.2 [22-41] vs. 27.9 [20-34]). Patients with SOLs showed higher survival (10/114 (8.8%) vs. 25/1,867 (1.3%), OR 1.96 [CI 1.20-2.72]) and higher favorable neurological outcomes (4/110 (3.5%) vs. 6/1,865 (0.3%), OR 2.42 [CI 1.14-3.70]) compared with patients without SOLs. Conclusions: TCA patients with SOLs at hospital arrival showed higher survival and favorable neurological outcomes at hospital discharge compared with TCA patients without SOLs.
RESUMO
BACKGROUND: Limited data are available on organ donation practices and recipient outcomes, particularly when comparing donors who experienced cardiac arrest and received extracorporeal cardiopulmonary resuscitation (ECPR) followed by veno-arterial extracorporeal membrane oxygenation (ECMO) decannulation, versus those who experienced cardiac arrest without receiving ECPR. This study aims to explore organ donation practices and outcomes post-ECPR to enhance our understanding of the donation potential after cardiac arrest. METHODS: We conducted a nationwide retrospective cohort study using data from the Japan Organ Transplant Network database, covering all deceased organ donors between July 17, 2010, and August 31, 2022. We included donors who experienced at least one episode of cardiac arrest. During the study period, patients undergoing ECMO treatment were not eligible for a legal diagnosis of brain death. We compared the timeframes associated with each donor's management and the long-term graft outcomes of recipients between ECPR and non-ECPR groups. RESULTS: Among 370 brain death donors with an episode of cardiac arrest, 26 (7.0%) received ECPR and 344 (93.0%) did not; the majority were due to out-of-hospital cardiac arrests. The median duration of veno-arterial ECMO support after ECPR was 3 days. Patients in the ECPR group had significantly longer intervals from admission to organ procurement compared to those not receiving ECPR (13 vs. 9 days, P = 0.005). Lung graft survival rates were significantly lower in the ECPR group (log-rank test P = 0.009), with no significant differences in other organ graft survival rates. Of 160 circulatory death donors with an episode of cardiac arrest, 27 (16.9%) received ECPR and 133 (83.1%) did not. Time intervals from admission to organ procurement following circulatory death and graft survival showed no significant differences between ECPR and non-ECPR groups. The number of organs donated was similar between the ECPR and non-ECPR groups, regardless of brain or circulatory death. CONCLUSIONS: This nationwide study reveals that lung graft survival was lower in recipients from ECPR-treated donors, highlighting the need for targeted research and protocol adjustments in post-ECPR organ donation.

Massive methanol exposure can lead to severe and detrimental effects that can result in death or brain death. As organs from patients with brain death after methanol ingestion are less likely to be recovered, these patients have been considered marginal donors. We present a case of successful multiple organ transplantation (heart, lungs, and kidneys) from a methanol-poisoned patient. Our experience illustrates that donor death from methanol intoxication does not preclude organ transplantation.
RESUMO
BACKGROUND: Each individual's unique health-related beliefs can greatly impact the patient-clinician relationship. When there is a conflict between the patient's preferences and recommended medical care, it can create a serious ethical dilemma, especially in an emergency setting, and dramatically alter this important relationship. CASE PRESENTATION: A 56-year-old man, who remained comatose after out-of-hospital cardiac arrest, was rushed to our hospital. The patient was scheduled for emergency coronary angiography when his adolescent daughter reported that she and her father held sincere beliefs against radiation exposure. We were concerned that she did not fully understand the potential consequences if her father did not receive the recommended treatment. A physician provided her with in depth information regarding the risks and benefits of the treatment. While we did not want to disregard her statement, we opted to save the patient's life due to concerns about the validity of her report. CONCLUSIONS: Variations in beliefs regarding medical care force clinicians to incorporate patient beliefs into medical practice. However, an emergency may require a completely different approach. When faced with a patient in a life-threatening condition and unconscious, we should take action to prioritize saving their life, unless we are highly certain about the validity of their advance directives.

BACKGROUND: Some COVID-19 patients develop life-threatening disease accompanied by severe pneumonitis. Teprenone induces expression of heat-shock proteins (HSPs) that protect against interstitial pneumonia in preclinical models. We explored whether teprenone prevented worsening of COVID-19 infections. METHODS: This open-label, randomized, pilot phase 2 clinical trial was conducted at five institutions in Japan. We randomized patients hospitalized for COVID-19 with fever to teprenone or no-teprenone groups in a 1:1 ratio. We stratified patients by sex, age < and ≥ 70 years and the existence (or not) of complications (hypertension, diabetes, ischemic heart disease, chronic pulmonary disease and active cancer). No limitation was imposed on other COVID-19 treatments. The primary endpoint was the intubation rate. RESULTS: One hundred patients were included, 51 in the teprenone and 49 in the no- teprenone groups. The intubation rate did not differ significantly between the two groups: 9.8% (5/51) vs. 2.0% (1/49) (sub-hazard ratio [SHR] 4.99, 95% confidence interval [CI]: 0.59-42.1; p = 0.140). The rates of intra-hospital mortality and intensive care unit (ICU) admission did not differ significantly between the two groups: intra-hospital mortality 3.9% (2/51) vs. 4.1% (2/49) (hazard ratio [HR] 0.78, 95%CI: 0.11-5.62; p = 0.809); ICU admission 11.8% (6/51) vs. 6.1% (3/49) (SHR 1.99, 95%CI: 0.51-7.80; p = 0.325). CONCLUSION: Teprenone afforded no clinical benefit. TRIAL REGISTRATION: Japan Registry of Clinical Trials jRCTs061200002 (registered on 20/May/2020).

Intramural esophageal dissection (IED), characterized by bleeding into the submucosal space, leads to mucosal separation and dissection. The most prevalent symptoms are sudden chest or retrosternal pain, hematemesis, and dysphagia. Therefore, acute coronary syndrome and aortic dissection are among its most notable differential diagnoses. A 31-year-old pregnant woman presented with acute chest pain, laryngeal discomfort, and hematemesis. Emergency esophagogastroscopy revealed longitudinal mucosal dissection (upper esophagus to esophagogastric junction). The patient was successfully treated by avoiding the ingestion of solid foods. Clinicians should consider a diagnosis of IED for pregnant patients with acute chest pain, especially if hematemesis is present.

BACKGROUND: Lung contusion caused by blunt chest trauma evokes a severe inflammatory reaction in the pulmonary parenchyma that may be associated with acute respiratory distress syndrome. Although hydrogen gas has antioxidant and anti-inflammatory effects and is protective against multiple types of lung injury at safe concentrations, the effects of inhaled hydrogen gas on blunt lung injury have not been previously investigated. Therefore, using a mouse model, we tested the hypothesis that hydrogen inhalation after chest trauma would reduce pulmonary inflammation and acute lung injury associated with lung contusion. METHODS: Inbred male C57BL/6 mice were randomly divided into 3 groups: sham with air inhalation, lung contusion with air inhalation, and lung contusion with 1.3% hydrogen inhalation. Experimental lung contusion was induced using a highly reproducible and standardized apparatus. Immediately after induction of lung contusion, mice were placed in a chamber exposed to 1.3% hydrogen gas in the air. Histopathological analysis and real-time polymerase chain reaction in lung tissue and blood gas analysis were performed 6 hours after contusion. RESULTS: Histopathological examination of the lung tissue after contusion revealed perivascular/intra-alveolar hemorrhage, perivascular/interstitial leukocyte infiltration, and interstitial/intra-alveolar edema. These histological changes and the extent of lung contusion, as determined by computed tomography, were significantly mitigated by hydrogen inhalation. Hydrogen inhalation also significantly reduced inflammatory cytokine and chemokine mRNA levels and improved oxygenation. CONCLUSION: Hydrogen inhalation therapy significantly mitigated inflammatory responses associated with lung contusion in mice. Hydrogen inhalation therapy may be a supplemental therapeutic strategy for treating lung contusion.

Background: Myxedema coma is an extremely rare but fatal endocrine emergency that requires urgent recognition and treatment. We describe a case of severe hypothermia that rapidly deteriorated to cardiac arrest that was attributed to myxedema coma. Case Presentation: A 52-year-old man without a history of hypothyroidism was transferred to our emergency department due to coma and profound hypothermia. The patient developed cardiac arrest immediately after hospital arrival but return of spontaneous circulation was achieved shortly after resuscitation. The patient was noted to have generalized, nonpitting edema, dry skin, severe respiratory acidosis, hyponatremia, and elevated creatinine kinase, which was indicative of hypothyroidism. Myxedema coma was confirmed by a thyroid profile. The patient was successfully treated with intravenous levothyroxine and glucocorticoid. Conclusion: Although myxedema coma is a rare cause of severe hypothermia, emergency physicians should be familiar with its clinical features and management.
RESUMO
OBJECTIVES: To examine the association of prehospital physician presence with neurologic outcomes of pediatric patients with out-of-hospital cardiac arrest (OHCA). DESIGN: Retrospective cohort study. SETTING: Data from the Japanese Association for Acute Medicine-OHCA Registry. INTERVENTIONS: None. PATIENTS: Pediatric patients (age 17 yr old or younger) registered in the database between June 2014 and December 2019. MEASUREMENT AND MAIN RESULTS: We used logistic regression models with stabilized inverse probability of treatment weighting (IPTW) to estimate the associated treatment effect of a prehospital physician with 1-month neurologically intact survival. Secondary outcomes included in-hospital return of spontaneous circulation (ROSC) and 1-month survival after OHCA. A total of 1,187 patients (276 in the physician presence group and 911 in the physician absence group) were included (median age 3 yr [interquartile range 0-14 yr]; 723 [61%] male). Comparison of the physician presence group, versus the physician absence, showed 1-month favorable neurologic outcomes of 8.3% (23/276) versus 3.6% (33/911). Physician presence was associated with greater odds of 1-month neurologically intact survival after stabilized IPTW adjustment (adjusted odds ratio [aOR] 1.98, 95% CI 1.08-3.66). We also found an association in the secondary outcome between physician presence, opposed to absence, and in-hospital ROSC (aOR 1.48, 95% CI 1.08-2.04). However, we failed to identify an association with 1-month survival (aOR 1.49, 95% CI 0.97-2.88). CONCLUSIONS: Among pediatric patients with OHCA, prehospital physician presence, compared with absence, was associated almost two-fold greater odds of 1-month favorable neurologic outcomes.

A 38-year-old primipara Japanese woman suffered cardiac arrest due to a pulmonary thromboembolism 1 day after undergoing a cesarean section. Extracorporeal cardiopulmonary resuscitation was initiated and extracorporeal membrane oxygenation support was needed for 24 h. Despite intensive care, the patient was diagnosed with brain death on day 6. With the family's consent, comprehensive end-of-life care including organ donation was discussed based on our hospital's policy. The family decided to donate her organs. Specific training and education are required for emergency physicians to optimize the process of incorporating organ donation into end-of-life care while respecting the patient's and family's wishes.

Healthcare providers are at risk of exposure to SARS-CoV-2 via droplets, respiratory secretions, and contact with contaminated surfaces. Personal protective equipment (PPE) is necessary for primary reliable prevention to treat patients with coronavirus disease 2019 (COVID-19). However, PPE shortages have had a significant impact on every medical facility, and outpatient clinics are especially vulnerable to shortages of medical supplies. During the first stage of the pandemic, efforts were made to reduce the use of medical supplies. Guidance and strategies were proposed to ration the use of PPE, including reusing it. However, reuse (wash) of isolation gowns has not been practically promoted despite these suggestions. Further, reusable products may have advantages for economic and ecologic reasons. We developed an adult universally sized, long-sleeved, 100% polyester, reusable/washable gown with liquid barrier protection. The isolation gown can be worn repeatedly through washing and subsequent disinfection, and it can withstand washing in 80°C hot water for 10 min and/or immersion in 0.05%-0.1% sodium hypochlorite for 30 min and then dried. This new gown's liquid barrier performance is at Association for the Advancement of Medical Instrumentation level 1, even after 20 repeated uses with low cost. The choice of barrier level for gowns should be made based on the risk of contamination. However, the healthcare setting for COVID-19 patients varies greatly with not fully elucidated transmissibility. The newly made reusable isolation gown can be one option for treating COVID-19 patients especially in low-risk settings with economical advantage. Further, preparedness for reuse may have critical implications in extreme shortage. Reconsideration should be focused on reusable gowns with liquid barrier performance and their appropriate use.
RESUMO
BACKGROUND: Patients with traumatic cardiac arrest (TCA) are known to have poor prognoses. In 2003, the joint committee of the National Association of EMS Physicians and the American College of Surgeons Committee on Trauma proposed stopping unsuccessful cardiopulmonary resuscitation (CPR) sustained for > 15 min after TCA. However, in 2013, a specific time-limit for terminating resuscitation was dropped, due to the lack of conclusive studies or data. We aimed to define the association between emergency medical services transport time and survival to demonstrate the survival curve of TCA. METHODS: A retrospective review of the Japan Trauma Data Bank. Inclusion criteria were age ≥ 16, at least one trauma with Abbreviated Injury Scale score (AIS) ≥ 3, and CPR performed in a prehospital setting. Exclusion criteria were burn injury, AIS score of 6 in any region, and missing data. Estimated survival rate and risk ratio for survival were analyzed according to transport time for all patients. Analysis was also performed separately on patients with sustained TCA at arrival. RESULTS: Of 292,027 patients in the database, 5336 were included in the study with 4141 sustained TCA. Their median age was 53 years (interquartile range (IQR) 36-70), and 67.2% were male. Their median Injury Severity Score was 29 (IQR 22-41), and median transport time was 11 min (IQR 6-17). Overall survival after TCA was 4.5%; however, survival of patients with sustained TCA at arrival was only 1.2%. The estimated survival rate and risk ratio for sustained TCA rapidly decreased after 15 min of transport time, with estimated survival falling below 1%. CONCLUSION: The chances of survival for sustained TCA declined rapidly while the patient is transported with CPR support. Time should be one reasonable factor for considering termination of resuscitation in patients with sustained TCA, although clinical signs of life, and type and severity of trauma should be taken into account clinically.

The aim of this study was to investigate the longitudinal relationship between shorter or irregular sleep duration (SD) in early childhood and increased risk of injury at primary school age using data from a nationwide survey in Japan. We categorized SD into seven groups: 6 h, 7 h, 8 h, 9 hrs, 10 or 11 h, >12 h, and irregular, based on questionnaire responses collected at 5.5 years old. The relationship between SD and incidence of injury at 5.5-nine years of age is shown. In addition, we completed a stratified analysis on children with or without problematic behavior at eight years old. We included 32,044 children, of which 6369 were classified as having an injury and 25,675 as not having an injury. Logistic regression model showed that shorter or irregular SD categories were associated with an increased adjusted odds ratio (aOR) for injuries (6 h: aOR 1.40, 95% confidence interval (CI) 1.19-1.66, 7 h: aOR 1.10, 95% CI, 0.98-1.23, 8 h: aOR 1.13, 95% CI, 1.02-1.26, irregular: aOR 1.26, 95% CI 1.10-1.43). The same tendency was observed with shorter or irregular SD in subgroups with or without behavioral problems. Shorter or irregular sleep habits during early childhood are associated with injury during primary school age.

INTRODUCTION: Most physicians are not familiar with postoperative changes to the orbit, so radiologists and clinicians may sometimes find it challenging to conduct a proper radiological assessment of the globe of the eye and orbital abnormalities. We present a patient with head trauma who had surgery for retinal detachment with implantation of silicone encircling bands. This case report may help clinicians recognize imaging characteristics after ophthalmic surgery to prevent misdiagnosis and unnecessary workup. Case Report. An 18-year-old man with severe head trauma was admitted to our hospital. Initial computed tomography (CT) revealed a high attenuation of intraocular silicone that could be mistaken for a hemorrhage. Ophthalmological examination and detailed ophthalmic history confirmed silicone oil in his eye for treatment of retinal detachment. Knowledge of the anatomical changes and radiological appearance of postsurgical findings following retinal detachment, including the surgical materials of silicone oil or bands, can prevent unnecessary alarm. CONCLUSION: Implanted ophthalmic devices, for example, silicone oil, appear similar to hemorrhages on CT and magnetic resonance imaging and cause diagnostic confusion. When in doubt, it is useful to assess the clinical presentation and obtain an accurate medical history.
RESUMO
AIM: Although uncommon, medical emergencies arise in general dental practice. Inadequate data on their severity and frequency makes targeting medical education for general dental practitioners difficult. This also makes planning for unexpected events challenging for practitioners and makes collaborating with emergency physicians burdensome. We aimed to clarify the incidence and characteristics of a dental outpatient department's medical emergencies. METHODS: This single-center, retrospective, observational study was undertaken with patients who visited the dental outpatient department of Okayama University Hospital during the 8-year period. The primary outcome of the study was to identify the incidence and characteristics of medical emergencies in the dental outpatient department. Then we examined the timing of medical emergencies, administered medications, and final disposition (home/admission). RESULTS: During the period, 1,146,929 patients were enrolled. Forty-two patients (0.0037%) were consulted as medical emergencies. More than 60% of the incidents were vasovagal syncope, and dehydration and hypoglycemia were the second most prevalent at 9.5%. The most common types of dental treatments were tooth extraction (45.2%), followed by general dental treatment (28.6%), and other dental surgery such as implant placement (14.3%). Types of medical emergencies occurred equally before, during, and after dental treatment. Antihypertensive agents, sedatives, or glucose were used. For patients with emergencies, 90.5% recovered during the day and returned home, and 9.5% were hospitalized. CONCLUSION: The incidence of medical emergencies was low in our dental outpatient department. Knowledge of basic management principles, regular education for emergency care, and practicing first aid skills are mandatory for safe patient management.
RESUMO
Plastic bronchitis is an uncommon disorder marked by the production of bronchial casts and acute respiratory failure development. In pediatric cases, influenza infection sometimes results in the obstruction of bronchi and leads to this potentially life-threatening condition. We report the case of a five-year-old boy with plastic bronchitis related to influenza A infection, which could only be recovered by the use of extracorporeal membrane oxygenation (ECMO). ECMO could effectively provide sufficient oxygenation for patients suffering from severe reversible acute respiratory failure. If patients infected with the influenza virus present acute respiratory distress with total lung atelectasis, clinicians should consider the diagnosis of plastic bronchitis and the subsequent treatment interventions with ECMO in a severe cases.
