Direct reinfusion of pericardial blood complications: A case of acute respiratory distress syndrome and disseminated intravascular coagulation.

Background: Direct reinfusion of pericardial blood during cardiac surgery triggers a systemic inflammatory response. Although various inflammatory mediators have been identified as triggers, the role of damage-associated molecular patterns (DAMPs) remains poorly understood. Despite guidelines recommending against this practice owing to its harmful effects, it is sometimes used in emergencies. Case Presentation: A 72-year-old man with atrial fibrillation and cerebral infarction developed cardiac tamponade during catheter ablation. He underwent pericardial drainage and direct blood reinfusion. He was transferred to our ICU, where he developed acute respiratory distress syndrome (ARDS) and disseminated intravascular coagulation (DIC). Despite aggressive management, the patient died 41 days after admission. Conclusion: This case highlights severe adverse events following direct reinfusion of pericardial blood. These findings suggest a significant role for DAMPs in mediating these inflammatory responses. Direct reinfusion of pericardial drainage blood should be avoided during emergencies to prevent life-threatening complications.

Clinical Impact of a Local Triage System Using the Emergent Large Vessel Occlusion Screen with a Rotation System of Thrombectomy-Capable Hospitals.

Objective: Early intervention with mechanical thrombectomy (MT) is expected to improve the functional outcome in patients with large vessel occlusion (LVO); however, a method for the effective detection of these patients in a prehospital setting and early transport to MT-capable hospitals has not been established. This study aimed to analyze the clinical impact and diagnostic performance of the emergent large vessel occlusion (ELVO) screen and its influence on the transportation time. Methods: The emergency medical services (EMS) in one of the secondary medical areas in Akita, Japan, introduced a prehospital triage system employing an ELVO screen and a rotation system of three MT-capable hospitals on December 1, 2021. Patients who were transferred to each of the three hospitals involved in the rotation system according to a predefined priority list from December 2021 to November 2022 were included in the triage group. Patients who underwent MT in the three hospitals before the introduction of the triage system were assigned to the pre-triage group. We compared the transportation time parameters between the two groups and analyzed the performance of the ELVO screen for the diagnosis of LVOs. This study was approved by the institutional review boards of all three hospitals. Results: Time parameters were compared between the 37 and 42 patients who underwent MT and had detailed data in the triage (n = 351) and pre-triage (n = 43) groups, respectively. The time from door to puncture tended to decrease in the triage group in all hospitals, with one hospital showing a statistically significant shortening of 14 min (p = 0.018). In the triage group, 209 ELVO screen-positive patients were present, with 60 (28.7%) of these having LVO. The sensitivity, specificity, positive and negative predictive values, and area under the curve of the ELVO screen to detect LVO under the present triage system were 87.0%, 47.2%, 28.7%, 93.7%, and 0.671, respectively. Conclusion: The present study demonstrated that the introduction of a triage system may have shortened the time required for MT. ELVO screen may be considered a useful marker for screening LVO in prehospital settings in terms of the sensitivity and negative predictive value; however, further improvement may be necessary to reduce the rate of false positive results.

Hyperthyroidism With Non-chylous Ascites: A Case Report.

Ascites is the accumulation of fluid in the abdominal cavity and is commonly attributed to various etiologies, including portal hypertension and peritoneal diseases. Hyperthyroidism is rarely associated with ascites, which is typically chylous and accompanied by high central venous pressure. We present a unique case of a 57-year-old woman with untreated hyperthyroidism who manifested non-chylous ascites without evidence of high venous pressure. Initially presenting with left lower leg pain, the patient presented with leg edema, abdominal distention, and diarrhea. A range of diagnostic tests ruled out common etiologies of ascites, such as liver cirrhosis, renal impairment, heart failure, infection, and malignancy. Ascites was characterized by low triglyceride levels, while no evidence of high venous pressure was found. Notably, the patient showed decreased levels of rapid turnover proteins, suggesting hypercatabolism and insufficient protein synthesis due to hyperthyroidism. Upon the initiation of antithyroid therapy, the patient's symptoms markedly improved. In conclusion, this report highlights a rare manifestation of hyperthyroidism that resulted in non-chylous ascites without high venous pressure. This underscores the need to include hyperthyroidism in the differential diagnosis of unexplained ascites, particularly in cases in which classical hyperthyroid symptoms are absent.

Retrospective observational study of changes in serum cytokines and adiponectin with continuous plasma exchange with dialysis therapy for severe COVID-19.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) is associated with a marked increase in the inflammatory cytokines, IL-6 and IL-18. Blood purification therapy aimed at controlling cytokines is one treatment option; however, evidence of its effectiveness is needed. Plasma exchange with dialysis (PED) is a blood purification method involving selective plasma exchange with dialysate flowing through the outer hollow fiber of the plasma separator. In this retrospective study, we investigated the efficacy of continuous PED (cPED) over 48 h in five patients with severe COVID-19. METHODS: We assessed changes in IL-6 and IL-18, as well as adiponectin (APN). RESULTS: There were no significant differences in changes in IL-6 and IL-18, but there was a marked improvement in cases with abnormally high IL-6 and IL-18 levels at baseline. APN, which inhibits inflammatory cytokines, was significantly elevated post-cPED. CONCLUSION: Our results suggest that cPED therapy is an effective treatment for COVID-19.

Contribution of traditional Japanese Kampo medicines, kakkonto with shosaikotokakikyosekko, in treating patients with mild-to-moderate coronavirus disease 2019: Further analysis of a multicenter, randomized controlled trial.

We previously reported the finding of symptom relief in a randomized controlled trial with the combined use of kakkonto and shosaikotokakikyosekko added to conventional treatment in patients with coronavirus disease 2019 (COVID-19). For further evaluation, we performed post hoc analysis focused on symptom disappearance without recurrence, to determine a clearer effect of Kampo medicine. Patients with mild and moderate COVID-19 were randomly allocated to a control group receiving symptomatic therapy or a Kampo group receiving kakkonto (2.5 g) with shosaikotokakikyosekko (2.5 g) three times daily in addition to symptomatic therapy. The data of 161 patients (Kampo group, n = 81; control group, n = 80) were analyzed post hoc for the time to symptom disappearance. Kaplan-Meier and Cox proportional hazard estimates of disappearance of symptoms showed that all and each symptom targeted in this study disappeared faster in the Kampo group than in the control group, although not statistically significant (all symptomatic cases; hazard ratio [HR] 3.73, 95% confidence interval [CI] 0.46-29.98, log-rank p = 0.1763). In a supplemental assessment using covariate adjustment and competing risk analysis, fever disappeared faster in the Kampo group than in the control group (all symptomatic cases, HR 1.62, 95% CI 0.99-2.64, p = 0.0557; unvaccinated cases, HR 1.68, 95% CI 1.00-2.83, p = 0.0498) and shortness of breath disappeared significantly faster in Kampo group than in control group (all symptomatic cases, HR 1.92, 95% CI 1.07-3.42, p = 0.0278; unvaccinated cases, HR 2.15, 95% CI 1.17-3.96, p = 0.0141). These results demonstrate the advantages of Kampo treatment for acute COVID-19.

Severe acute respiratory distress syndrome caused by Otsujito.

Background: Kampo prescriptions can cause drug-induced lung injury (DLI) and acute respiratory distress syndrome (ARDS). However, severe respiratory failure induced by Otsujito (OJT) is extremely rare. High-dose steroid pulse therapy is generally given to patients with severe DLI. Case Presentation: A 63-year-old man with respiratory distress was admitted to our hospital. The patient was diagnosed with severe ARDS caused by OJT, which had been prescribed 4 weeks prior to admission. Thus, OJT was discontinued, and intensive care for ARDS, including ventilation and prone positioning, was implemented. His respiratory condition rapidly improved after treatment with an initial methylprednisolone dose (1.5 mg/kg/day). He was extubated on day 4 and discharged on day 16. The steroid dose was gradually reduced and discontinued by day 116. Conclusion: A severe case of ARDS caused by OJT was successfully treated with low-dose steroids and specialized intensive care.

Chest Pain Diagnosed as Acute Leukemia: Focus on Coagulation Abnormalities Rather Than White Blood Cell Count.

Chest pain is an important symptom for emergency physicians. It is one of the most common causes for admission in emergency departments. Acute leukemia (AL) rarely causes chest symptoms due to ostalgia, and it is difficult to diagnose leukemia as the cause of chest pain. An 83-year-old woman with no history of trauma presented to the emergency department with a one-day history of severe chest pain. There were no abnormalities on electrocardiography, echocardiography, specific biomarkers for cardiac injury, or contrast computed tomography of the chest and pelvis. The white blood cell count was normal, but the patient had prominent thrombocytopenia with platelets of 68,000/µL, prothrombin time-international normalized ratio (PT-INR) of 1.2, activated partial thromboplastin time (APTT) of 25.3 s, and D-dimer of 73.55 µg/mL. Due to the holiday, blast cells could not be measured on the same day. The next day's examination revealed blast cells in the peripheral blood. The patient was admitted to the hematology department and discharged three months later. This case suggests the need to consider AL in chest pain associated with coagulation abnormalities and thrombocytopenia, regardless of the white blood cell count.

Objective evaluation of tongue diagnosis ability using a tongue diagnosis e-learning/e-assessment system based on a standardized tongue image database.

Background: In Kampo medicine, tongue examination is used to diagnose the pathological condition "Sho," but an objective evaluation method for its diagnostic ability has not been established. We constructed a tongue diagnosis electronic learning and evaluation system based on a standardized tongue image database. Purpose: This study aims to verify the practicality of this assessment system by evaluating the tongue diagnosis ability of Kampo specialists (KSs), medical professionals, and students. Methods: In the first study, we analyzed the answer data of 15 KSs in an 80-question tongue diagnosis test that assesses eight aspects of tongue findings and evaluated the (i) test score, (ii) test difficulty and discrimination index, (iii) diagnostic consistency, and (iv) diagnostic match rate between KSs. In the second study, we administered a 20-question common Kampo test and analyzed the answer data of 107 medical professionals and 56 students that assessed the tongue color discrimination ability and evaluated the (v) correct answer rate, (vi) test difficulty, and (vii) factors related to the correct answer rate. Result: In the first study, the average test score was 62.2 ± 10.7 points. Twenty-eight questions were difficult (correct answer rate, <50%), 34 were moderate (50%-85%), and 18 were easy (≥85%). Regarding intrarater reliability, the average diagnostic match rate of five KSs involved in database construction was 0.66 ± 0.08, and as for interrater reliability, the diagnostic match rate between the 15 KSs was 0.52 (95% confidence interval, 0.38-0.65) for Gwet's agreement coefficient 1, and the degree of the match rate was moderate. In the second study, the difficulty level of questions was moderate, with a correct rate of 81.3% for medical professionals and 82.1% for students. The discrimination index was good for medical professionals (0.35) and poor for students (0.06). Among medical professionals, the correct answer group of this question had a significantly higher total score on the Kampo common test than the incorrect answer group (85.3 ± 8.4 points vs. 75.8 ± 11.8 points, p < 0.01). Conclusion: This system can objectively evaluate tongue diagnosis ability and has high practicality. Utilizing this system can be expected to contribute to improving learners' tongue diagnosis ability and standardization of tongue diagnosis.

Severe Drug-Induced Liver Injury From Over-the-Counter Medication.

Drug-induced liver injury (DILI) is difficult to diagnose as it presents with a wide variety of clinical manifestations and there is no established specific biomarker. However, clinicians require expertise in diagnosing DILI as it can lead to critical illness, is relatively common, and can be caused by a variety of drugs, herbal medicines, and supplements. A 67-year-old male was admitted to the hospital with a fever, jaundice, and fatigue. Abdominal ultrasonography, computed tomography, and magnetic resonance cholangiopancreatography revealed no morphological abnormalities in the hepatobiliary system. On the third day of hospitalization, the liver damage and acute kidney injury progressed, and the patient was transferred to our intensive care unit. To further investigate the cause of multiple organ damage, the patient underwent repeated history taking and additional laboratory testing. In addition to the common causes of hepatic and renal damage, we also tested for rickettsiosis and leptospirosis, as the patient reported partaking regularly in outdoor leisure activities. On day seven of hospitalization, the patient recalled taking over-the-counter herbal flu medications approximately five days prior to admission; therefore, we suspected DILI and performed a drug-induced lymphocyte stimulation test (DLST). The DLST was positive for one drug. As other causes had been ruled out, the patient was diagnosed with severe DILI. The clinical course of the patient was observed with the patient's laboratory data and fever improving spontaneously. This case taught us several important lessons for the investigation of liver injury. Firstly, even with over-the-counter drugs, liver injury can be severe. Secondly, while the DLST is available for investigating DILI, false positives, especially for medicinal herbs, should be noted, and it is necessary to adequately rule out other diseases. Finally, when the cause of liver injury is unclear, patient history taking should be repeated carefully.

Conventional and Kampo Medicine Treatment for Mild-to-moderate COVID-19: A Multicenter, Retrospective, Observational Study by the Integrative Management in Japan for Epidemic Disease (IMJEDI Study-observation).

Objective Patients in whom coronavirus disease 2019 (COVID-19) was suspected or confirmed between January 1, 2020, and October 31, 2021, were enrolled from Japanese hospitals in this multicenter, retrospective, observational study. Methods Data on the treatment administered (including conventional and Kampo medicine) and changes in common cold-like symptoms (such as fever, cough, sputum, dyspnea, fatigue, and diarrhea) were collected from their medical records. The primary outcome was the number of days without a fever (with a body temperature <37°C). The secondary outcomes were symptomatic relief and the worsening of illness, defined as the presence of a condition requiring oxygen inhalation. The outcomes of patients treated with and without Kampo medicine were compared. Patients We enrolled 962 patients, among whom 528 received conventional and Kampo treatment (Kampo group) and 434 received conventional treatment (non-Kampo group). Results Overall, after adjusting for the staging of COVID-19 and risk factors, there were no significant between-group differences in the symptoms or number of days being afebrile. After performing propensity score matching and restricting the included cases to those with confirmed COVID-19 who did not receive steroid administration and initiated treatment within 4 days from the onset, the risk of illness worsening was significantly lower in the Kampo group than in the non-Kampo group (odds ratio=0.113, 95% confidence interval: 0.014-0.928, p=0.0424). Conclusion Early Kampo treatment may suppress illness worsening risk in COVID-19 cases without steroid use. Further randomized controlled studies are needed to confirm the clinical benefit of Kampo medicine for COVID-19.

Multicenter, randomized controlled trial of traditional Japanese medicine, kakkonto with shosaikotokakikyosekko, for mild and moderate coronavirus disease patients.

The traditional Japanese (Kampo) medicine, kakkonto with shosaikotokakikyosekko, has antiviral and anti-inflammatory effects. In this randomized trial, patients with mild and moderate coronavirus disease (COVID-19) were randomly allocated to the control group receiving conventional treatment for symptom relief such as antipyretics and antitussives or the Kampo group receiving mixed extract granules of kakkonto (2.5 g) and shosaikotokakikyosekko (2.5 g) three times a day for 14 days in addition to conventional treatment. The main outcome was the number of days until total symptom relief. The secondary outcome was the number of days until each symptom's relief and whether the disease progressed to respiratory failure. We enrolled a total of 161 patients (Kampo group, n = 81; control group, n = 80). The results from Kaplan-Meier estimates of symptom relief showed that there are no significant differences between the groups. However, covariate-adjusted cumulative incidence of fever relief considering competitive risk showed that the recovery was significantly faster in the Kampo group than in the control group (HR 1.76, 95% CI 1.03-3.01). Additionally, the risk of disease progression to moderate COVID-19 requiring oxygen inhalation was lower in the Kampo group than in the control group (Risk Difference -0.13, 95% CI -0.27-0.01). No significant drug-related side effects were observed. Kakkonto with shosaikotokakikyosekko is effective for fever relief with suppression of disease progression in COVID-19 patients.

Application of Traditional Japanese Drug Jidabokuippo in a Modern Society.

Background: Jidabokuippo (JDI) () has been used in Japan to alleviate contusion-induced swelling and pain since medieval times. Method: This review investigated the effects of JDI on various symptoms in patients with trauma or static blood[TM1]. The PubMed and Igaku Chuo Zasshi databases were searched until 24 December 2021. We summarize the benefits of applying JDI to inflammatory conditions, including bruises. Results: JDI has been used to resolve blood [TM1] stasis, regulate qi in trauma patients, and treat inflammatory swelling and pain caused by rheumatoid arthritis and cellulitis. As the adverse event rate associated with JDI is low (1.3%), JDI is considered a safe drug. Conclusion: JDI can be used to resolve blood[TM1] stasis in trauma patients without adverse events associated with nonsteroidal anti-inflammatory drugs.

Baclofen Withdrawal With Reversible Posterior Leukoencephalopathy Syndrome: Bacterial Meningitis Mimicker.

BACKGROUND: The intrathecal baclofen (ITB) pump is an effective treatment for patients with spasticity unresponsive to oral medication. CASE REPORT: A 31-year-old woman with spinal cord injury sequelae was admitted to the emergency department due to sudden headache and excessive confusion. The patient was on ITB for lower limb spasticity. On presentation, her vital signs revealed blood pressure of 171/106 mm Hg, heart rate of 141 beats/min, and temperature of 39.0°C. Antibiotics were promptly administered intravenously for suspicion of bacterial meningitis. Based on magnetic resonance imaging and cerebrospinal fluid findings, as well as clinical signs such as marked lower limb spasticity, the final diagnosis was determined to be baclofen withdrawal syndrome complicated by reversible posterior leukoencephalopathy syndrome (RPLS). Improved consciousness was quickly achieved on blood pressure control. Resolution of spasticity was achieved after intravenous midazolam and intrathecal baclofen via lumbar puncture. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Baclofen withdrawal syndrome is the leading differential diagnosis for impaired consciousness and fever among patients using ITB pumps. Moreover, baclofen withdrawal syndrome mimics a wide variety of conditions, including sepsis. This unique case was complicated by intrathecal baclofen withdrawal syndrome coexisting with RPLS, thus presenting more similarly to bacterial meningitis than the usual baclofen withdrawal, due to marked headache, altered consciousness, and generalized convulsive symptoms. In addition to general withdrawal management, commencement of antihypertensive therapy for RPLS may have an immediate effect on the improvement of impaired consciousness.
