RESUMO

Studies on targeted temperature management for postcardiac arrest syndrome have shown no difference in outcomes between normothermia and hypothermia in patients with postcardiac arrest brain injury. Therefore, further development of therapeutic methods for temperature control in cardiac arrest patients is desirable. Although animal studies have shown that inducing hypothermia during cardiac arrest improves outcomes, no clinically effective method has yet been reported. We investigated whether intra-arrest lung cooling (IALC) effectively lowers brain temperature. A device capable of cooling oxygen was developed. The pigs were subjected to cardiac arrest using the device, ventilated, cooled during cardiopulmonary resuscitation, and resuscitated for 1 hour, with changes in brain temperature closely monitored. A device capable of cooling oxygen to -30°C was used to cool the lungs during cardiac arrest. Through this approach, IALC successfully reduced the brain temperature. Optimal cooling efficiency was observed when chest compressions and ventilation were synchronized at a ratio of 5:1, resulting in an approximate brain temperature reduction of 1.5°C/h. Our successful development of an oxygen-cooling device underscores the potential for lowering brain temperature through IALC using inhaled oxygen cooling.

RESUMO

In this single-center, retrospective, observational study, we aimed to assess the severity at which patients with trauma tend to develop metabolic disturbances that worsen their Controlling Nutritional Status (CONUT) scores. Participants were general adult patients with trauma hospitalized for at least one week. Injury Severity Scores (ISSs) at admission and CONUT scores one week later were calculated, and correlation coefficients were examined. The receiver operating characteristic (ROC) curve was used to calculate the ISS cutoff value for a CONUT score of 5 or more on day 7 of hospitalization. The ISS was assessed using multiple logistic regression analysis to determine whether it predicts worse nutritional status. Forty-nine patients were included. ISSs correlated with CONUT scores on day 7 (r = 0.373, p = 0.008). Using the ROC curve, the cutoff value for the ISS was 23.5. Multiple logistic regression analyses showed that a high ISS (odds ratio [OR], 1.158; 95% confidence interval [CI], 1.034-1.296; p = 0.011) and older age (OR, 1.094; 95% CI, 1.027-1.165; p = 0.005) were associated with a CONUT score 5 or more on day 7 of hospitalization. Patients with trauma with an ISS of 24 or higher have worsening CONUT scores during hospitalization; these patients require careful nutritional management.

RESUMO

Dextromethorphan (DXM) is used to treat colds and coughs; however, it can cause central nervous system symptoms, such as severe serotonin syndrome (SS). To our knowledge, there is no specific treatment for severe DXM poisoning, and there are no reports on the clinical use of intravenous lipid emulsion (ILE) for its treatment. Herein, we report a case of severe DXM poisoning with SS that was successfully treated with ILE. An older adolescent male visited the emergency department 1 h after ingesting 4500 mg of DXM orally. Physical examination revealed generalized convulsions, muscle rigidity, mydriasis (8.0/8.0 mm), and flushed skin, with a Glasgow Coma Scale score of 8 (E3V1M4). Severe DXM poisoning with SS was diagnosed. The patient was intubated and administered midazolam for continuous convulsions and SS. Activated charcoal was also administered, and body surface cooling was performed. After an 11 h intensive care unit admission, SS with mydriasis (6.0/6.0 mm) did not improve. Subsequently, 1100 mL of 20% soybean oil was injected as an ILE. Mydriasis improved (3.5/3.5 mm) 30 min after ILE administration; simultaneously, blood DXM concentration rapidly increased approximately two-fold. After discontinuing midazolam, the patient's consciousness signs improved, and he was weaned off the ventilator. SS was cured with no recurrence of convulsions. In cases of DXM poisoning with severe central nervous system disorders, such as SS, ILE treatment can potentially be an effective therapeutic option. For oral overdose cases, where the drug may remain in the intestinal tract, measures such as administering activated charcoal should be taken before administering ILE.

RESUMO

Introduction and importance: In endovascular treatment of ruptured pseudoaneurysm after pancreaticoduodenectomy (PD) with gastrointestinal bleeding, treatment for vasospasm of the culprit vessel from haemorrhagic shock and subsequent reperfusion has not been determined before. Case presentation: The authors hereby present you with a case of a 59-year-old man with unknown operative method upon arrival at the Emergecy room and who had hematemesis and collapse 6 months post-PD surgery. Clinical discussion: An initial contrast-enhanced computed tomography (CT) revealed no obvious source of bleeding, so an upper gastrointestinal endoscope was performed. Rebleeding occurred during the examination, and interventional radiology was performed because haemostasis was difficult. Coil embolization was performed for leakage of contrast material from the gastroduodenal artery stump into the gastrointestinal tract. However, because the embolization was uncertain due to vasospasm of the common hepatic artery, endoscopic clipping of the perforation site was also performed to prevent rebleeding due to reperfusion after improvement of vasospasm. A CT scan 5 days later showed reperfusion of the coil-implanted vessel. No rebleeding or hepatic infarction occurred postoperatively. Conclusion: In this case, the haemostasis by coil embolization was uncertain due to the presence of vasospasm, and clipping was used in combination with the procedure to prevent rebleeding.

RESUMO

RATIONALE: The symptoms of impaired consciousness and unilateral motor impairments are a perfect scenario for cerebral infarction, and a physician can easily miss the findings of limb ischemia on the patient paralyzed side even if acute limb ischemia (ALI) occurs on that side. The purpose of this case report is to reiterate the need to suspect ALI in patients with impaired consciousness who cannot complain of symptoms such as abnormal limb paresthesia or pain. PATIENT CONCERNS: An 89-year-old woman with impaired consciousness and motor impairment of the left upper and lower extremities was transported to our hospital. DIAGNOSES: Brain magnetic resonance imaging showed a suspected cerebral infarction in the posterior circulation; contrast-enhanced computed tomography showed occlusion of the left axillary artery and left femoral artery; and ultrasonography showed occlusion of the right popliteal artery. INTERVENTIONS: Cerebral angiography was performed simultaneously with surgical thrombectomy to treat the ALI. Mechanical thrombectomy was not performed for cerebral infarction. OUTCOMES: Although motor impairment of the left upper and lower extremities persisted, the patient successfully underwent limb salvage. LESSONS: Both cerebral infarction and ALI require early diagnosis and treatment. This rare case of cerebral infarction complicated by ALI emphasizes the need to avoid missing the signs of ALI in patients with impaired consciousness.

RESUMO

Drug overdose can lead to a range of symptoms, including potentially life-threatening cardiac arrhythmias. However, identifying the specific causative drug upon admission can be challenging in many cases. The toxidrome approach is a method that utilizes toxidromes, which are collections of findings obtained from physical examination and ancillary tests, that may be caused by a specific toxin. In this particular case, a man presented with an unknown drug overdose that caused symptoms indicative of anticholinergic effects and abnormal electrocardiogram (ECG) findings. The ECG revealed an R wave in lead aVR, S waves in leads I and aVL, and wide QRS tachycardia with a Brugada pattern. Shortly after arrival, the patient developed cardiac arrest due to a lethal arrhythmia. Prompt initiation of venoarterial extracorporeal cardiopulmonary membrane oxygenation (VA-ECMO) was performed. Fortunately, the patient achieved full neurological recovery, and the overdosed drug was identified as diphenhydramine. When diagnosing and treating drug overdose caused by an unidentified substance, diphenhydramine toxicity should be considered when an anticholinergic toxidrome is present and a Brugada pattern is observed on the ECG. VA-ECMO demonstrates potential as a viable treatment option when initial interventions prove ineffective.

RESUMO

Patient outcomes for severe sepsis and septic shock remain poor. Excessive oxidative stress accelerates organ dysfunction in severe acute illnesses. Uric acid (UA) is the most abundant antioxidant. We hypothesized that UA and related molecules, which play a critical role in antioxidant activity, might be markers of oxidative stress in sepsis. The study aimed to clarify the clinical significance of UA and the relationship between UA, molecules related to UA, and outcomes by measuring blood UA, xanthine dehydrogenase (XDH), and 8-hydroxy-2-deoxyguanosine (8-OHdG) levels over time. Blood UA levels in septic patients were correlated with the SOFA score (ρ = 0.36, p < 0.0001) and blood XDH levels (ρ = 0.27, p < 0.0001). Blood XDH levels were correlated with the SOFA score (ρ = 0.59, p < 0.0001) and blood 8-OHdG levels (ρ = -0.32, p < 0.0001). Blood XDH levels were persistently high in fatal cases. Blood XDH level (OR 8.84, 95% CI: 1.42-91.2, p = 0.018) was an independent factor of poor outcomes. The cutoff of blood XDH level was 1.38 ng/mL (sensitivity 92.8%, specificity 61.9%), and those 1.38 ng/mL or higher were associated with a significantly reduced survival rate (blood XDH level > 1.38 ng/mL: 23.7%, blood XDH level < 1.38 ng/mL: 96.3%, respectively, p = 0.0007). Elevated UA levels due to elevated blood XDH levels in sepsis cases may reduce oxidative stress. Countermeasures against increased oxidative stress in sepsis may provide new therapeutic strategies.

RESUMO

Although elevated blood ketone body levels reduce major adverse cardiac and cerebrovascular events (MACCEs) risk in chronic heart failure, their relationship with acute myocardial infarction remains unknown. We investigated this relationship in patients with acute myocardial infarction. This single-institution retrospective observational study analyzed data from 114 patients with acute myocardial infarction at Nihon University Hospital from May 1, 2018, to November 1, 2022. The cut-off value of acetoacetate for the incidence of in-hospital MACCE was determined by drawing a receiver operating characteristic curve (ROC) and defining patients with acetoacetate above and below the optimal cut-off point value as ROC and low-acetoacetate (LA) groups, respectively. Propensity score matching was performed between the LA and high-acetoacetate (HA) groups. Sex, peak creatine kinase, lactate, and blood glucose were defined as confounding factors between in-hospital MACCEs and acetoacetate, and 1:1 propensity score matching between the LA and HA groups was used, resulting in 40 patients from both groups enrolled in the analysis. There was a significantly lower incidence of in-hospital MACCEs in the HA group (LA group: 9 [22%] vs HA group: 1 [3%], P = 0.014). In conclusion, in acute myocardial infarction, elevated blood acetoacetate levels reduce the risk of MACCE.

RESUMO

A 50-year-old man was admitted to our hospital with hypotension and bradycardia after receiving high doses of atenolol, amlodipine, and etizolam. He had a drug-induced J wave on electrocardiography and subsequently underwent cardiac arrest. The patient was successfully rescued by venoarterial extracorporeal membrane oxygenation (VA-ECMO) and a good neurological outcome was achieved with therapeutic hypothermia (TH). In patients with J waves, TH is thought to increase the J waves and cause fatal arrhythmias, but in this case, rapid cooling with VA-ECMO allowed the patient to successfully complete TH.

RESUMO

Rapid hospital arrival decreases mortality risk in heat-related illnesses. We investigated an easy-to-use indicator of life-threatening severity of heat-related illnesses in a community setting to enable quick hospitalization by using data extracted from prehospital transportation records of a database from 2016 that included information on the clinical severity of suspected heat-related illnesses in patients (n = 2528) upon hospital arrival. Patient-related risk factors (adjusted odds ratio, aOR [95% confidence interval, CI]) included age, vital signs, location of the patient, and illness severity, and respiratory rate (3.34 [1.80-6.22]), heart rate (2.88 [1.57-5.29]), axillary body temperature (7.79 [4.02-15.1]), and consciousness level (38.3 [5.22-281.1]) were independent risk factors for heat-related illness severity. On-site blood pressure was not an independent factor for illness severity. Heart rate > 120 beats/min, respiratory rate > 24 breaths/min, and temperature > 38.6 °C (highest areas under the receiver operating characteristic curves [95% CI]: 0.80 [0.75-0.87]; 0.73 [0.67-0.81]; and 0.83 [0.77-0.91], respectively) predicted life-threatening illness severity. Changes in the vital signs of patients with heat-related illnesses, particularly tachycardia and tachypnea, constitute sensitive, easy-to-use indicators that facilitate rapid identification of severity by laypersons and transport of patients before aggravation to a life-threatening situation.

RESUMO

BACKGROUND: Reactive thrombocytosis occurs secondary to systemic infections, inflammatory, and other conditions. The relationship between thrombocytosis and acute pancreatitis (AP) in inflammatory diseases is uncertain. This study aimed to evaluate the clinical significance of thrombocytosis in AP patients during hospitalization. METHODS: Subjects within 48 h of AP onset were consecutively enrolled over 6 years. Platelet counts of ≥ 450,000/µL were defined as thrombocytosis, < 100,000/µL as thrombocytopenia, and other counts as normal. We compared clinical characteristics, including the rate of severe AP (SAP) assessed by the Japanese Severity Score; blood markers, including hematologic and inflammatory factors and pancreatic enzymes during hospitalization; and pancreatic complications and outcomes in the three groups. RESULTS: A total of 108 patients were enrolled. Although, SAP was more common in patients with thrombocytosis and thrombocytopenia (87.9% and 100%, respectively), the differences in lymphocytes and C-reactive protein, lactase dehydrogenase, and antithrombin levels, which are factors of the systemic inflammatory response, and the mean platelet volume, an indicator of platelet activation, were observed among patients with thrombocytosis and thrombocytopenia during hospitalization. Regarding pancreatic complications and outcomes, patients with thrombocytosis and thrombocytopenia had higher acute necrotic collection (ANC), pancreatic necrosis, intestinal paralysis, respiratory dysfunction, and pancreatic-related infection levels than patients with normal platelet levels. The relationship between pancreatic complications and thrombocytosis was assessed by multivariate logistic regression; the odds ratios for development of ANC, pancreatic necrosis and pancreatic-related infections were 7.360, 3.735 and 9.815, respectively. CONCLUSIONS: Thrombocytosis during hospitalization for AP suggests development of local pancreatic complications and pancreatic-related infections.

RESUMO

Brain damage in acute sepsis may be associated with poor long-term outcomes that impair reintegration into society. We aimed to clarify whether brain volume reduction occurs during the acute phase of sepsis in patients with acute brain damage. In this prospective, noninterventional observational study, brain volume reduction was evaluated by comparing head computed tomography findings at admission with those obtained during hospitalization. We examined the association between brain volume reduction and performance of the activities of daily living in 85 consecutive patients (mean age, 77 ± 12.7 years) with sepsis or septic shock. The bicaudate ratio increased in 38/58 (65.5%) patients, Evans index increased in 35/58 (60.3%) patients, and brain volume by volumetry decreased in 46/58 (79.3%) patients from the first to the second measurement, with significant increases in the bicaudate ratio (P < 0.0001) and Evans index (P = 0.0005) and a significant decrease in the brain volume by volumetry (P < 0.0001). The change rate for brain volume by volumetry was significantly correlated with the Katz index (ρ = -0.3790, P = 0.0094). In the acute phase of sepsis in this sample of older patients, 60-79% of patients showed decreased brain volumes. This was associated with a decreased capacity for performing activities of daily living.

RESUMO

RATIONALE: Altered autonomic responses can be observed in patients in the intensive care unit (ICU), and these changes in abnormal autonomic responses are known to be associated with patient prognosis. Therefore, it is important to monitor autonomic nervous system activity in these critically ill patients. While the utility of monitoring critically ill patients using heart rate (HR) variability measurements has been reported, portable automated pupillometers are small, lightweight, and easy-to-operate medical devices that may be more easily evaluated for autonomic nervous system function. PATIENT CONCERNS: An unconscious 80-year-old female patient with chronic obstructive pulmonary disease was brought to the medical emergency department after a call from her caregiver. DIAGNOSIS: On arrival, the patient's Glasgow coma scale score was 7, her blood pressure was 140/80 mm Hg, her HR was 114 bpm, and her respiratory rate was 27 breaths/minutes with increased breathing effort. Oxygen saturation was 90% on a venturi mask (3 L of supplemental oxygen). The arterial blood gas analysis showed a pH of 7.196, a partial pressure of carbon dioxide (CO2) of 89.6 mm Hg, a partial pressure of oxygen of 87.5 mm Hg, and a bicarbonate level of 29.4 mmol/L. Other than CO2 narcosis, there were no abnormal findings to induce impaired consciousness. The patient did not respond to support with a bag-valve mask and was intubated. One hour after intubation, her impaired consciousness improved. The patient was extubated 20 hours later and discharged on Day 3. INTERVENTIONS: The patient was admitted to the ICU after being intubated, where vital signs and blood gas analysis were monitored every 2 hours, and consciousness was assessed using the Glasgow coma scale. Using a portable automated pupillometer (NeurOptics NPi™-200, Neuroptics Inc., Irvine, CA), pupillary responses, including pupil size or light reflex, were measured every 2 hours during ICU stay. OUTCOMES: Changes in respiratory rate and partial pressure of CO2 values correlated with pupil size and constriction velocity, but HR changes were contrary. LESSONS: Pupillary responses exhibited by automated pupillometers observed in patients with CO2 narcosis may be linked to vital signs and allow for autonomic evaluation.

RESUMO

Vaccines for tetanus prevention have rapidly progressed, and the number of outbreaks, especially the incidence of tetanus in developed countries, has decreased dramatically. However, the mortality rate associated with severe tetanus remains high. Tetanus eradication is difficult owing to the widespread presence of the spores of tetanus bacteria in the environment, but tetanus can be prevented by acquired immunity from vaccines. Older people, intravenous drug users, and migrants are at a high risk of tetanus in developed countries owing to the lack of booster vaccination programs. Natural disasters, especially floods, often cause an increase in the prevalence of tetanus because of the associated injuries. Precautions should be taken to combat the threat of a new tetanus outbreak due to floods in urban areas owing to global warming. In particular, Japan is facing a high risk of urban flooding-induced tetanus, despite its status as a developed country. This review aims to highlight the data on the epidemiology, causes, treatment, and prevention of tetanus and problems associated with tetanus countermeasures during future floods.

RESUMO

This study aimed to clarify whether the influence of undernutrition status and the degree of glycemic disorders affected the prognosis of patients with sepsis. A total of 307 adult patients with sepsis were retrospectively enrolled and analyzed. Characteristics, including nutrition status, calculated according to the Controlling Nutritional Status (CONUT) score of survivors and non-survivors, were examined. The independent prognostic factors of these patients with sepsis were extracted using multivariable logistic regression analysis. The CONUT scores in three glycemic categories were compared. Most patients with sepsis (94.8%) in the study had an undernutrition status according to their CONUT scores. High CONUT scores (odds ratio, 1.214; p = 0.002), indicating a poor nutritional status, were associated with high mortality. The CONUT scores in the hypoglycemic group were significantly higher than those in other groups with an undernutrition status (vs. hyperglycemic, p < 0.001; vs. intermediate glycemic, p = 0.006). The undernutrition statuses of patients with sepsis in the study scored using the CONUT were independent predictors of prognostic factors.

RESUMO

BACKGROUND: Amoxapine is a second-generation tricyclic antidepressant with a greater seizure risk than other antidepressants. If administered in large amounts, amoxapine can cause severe toxicity and death. Therefore, it is necessary to terminate seizures immediately if amoxapine toxicity occurs. However, intractable seizures often occur in these patients. We describe a case of intractable seizures caused by amoxapine poisoning, in which intravenous lipid emulsion (ILE) was used successfully. CASE REPORT: A 44-year-old woman with a history of depression ingested 3.0 g of amoxapine during a suicide attempt. Although she was initially treated with intravenous diazepam, her seizures persisted. Levetiracetam and phenobarbital were then administered, but seizures persisted. Hence, ILE was injected for over 1 min. At 2 min after ILE administration, the patient's status seizures ceased. Recurrence of seizures was observed 30 min after ILE, and the seizures disappeared after re-administration of ILE. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: ILE may be effective in amoxapine intoxication. Emergency physicians may consider ILE as an adjunctive therapy for amoxapine poisoning with a high mortality rate. ILE should be implemented carefully with monitoring of total dosage and adverse events.

RESUMO

Purpose: The characteristics of patients with severe COVID-19 pneumonia who underwent direct hemoperfusion using polymyxin B-immobilized fiber column (PMX-DHP), in addition to steroids and immunomodulators, remain unclear. Patients and Methods: We conducted a retrospective observational study on 31 patients with severe COVID-19 pneumonia treated with PMX-DHP in an intensive care unit (ICU) from December 2020 to September 2021. Results: Outcomes 28 days after admission to the ICU were 20 in the survival group and 11 in the death group. Parameters significantly different between the survival and death group before PMX-DHP were percentage of invasive mechanical ventilation (25% vs 72.7%, P = 0.0209), PaO2/FIO2 (P/F) ratio (104.5 vs 75, P = 0.0317), and sequential organ failure assessment (SOFA) score (2 vs 3, P = 0.0356). Invasive mechanical ventilation avoidance rate was significantly different between the survival (100%) and death group (0%) (P = 0.0012). P/F ratio, respiratory ratio (RR), and lymphocyte counts improved significantly after PMX-DHP for all patients. The lymphocyte counts changed significantly in the survival (P < 0.0001), but not the death group (P = 0.7927). Conclusion: PMX-DHP, in addition to steroids and immunomodulators, may improve oxygenation and alleviate tachypnea by modulating the lymphocyte numbers and levels of various mediator against severe COVID-19 pneumonia. It may be better to perform PMX-DHP before multi organ dysfunction and lung injury has progressed. Furthermore, the early increase in lymphocyte counts after PMX-DHP might be an indicate a positive outcome.

RESUMO

BACKGROUND: To the best of our knowledge, splenic rupture caused by hit by a pitch (HBP) has not been previously reported. We present a patient who underwent emergency laparotomy for splenic rupture after being HBP during a baseball game. CASE PRESENTATION: A 41-year-old male was HBP in the left abdomen during his first at-bat during a baseball game. During the operation, vascular injury of the splenic hilum and a deeply extending parenchymal injury were observed, and splenectomy was performed. Histologic findings were consistent with splenic rupture. CONCLUSIONS: The patient's postoperative course was uneventful. Although extremely rare, the possibility of intra-abdominal organ injury should be considered in batters who are hit in the abdomen by a pitched baseball, as illustrated by our patient.
