Refractory gastric ulcer due to undisclosed use of topical diclofenac epolamine patches

Background: Topical forms of nonsteroidal anti-inflammatory drugs (NSAIDs) have been created to lessen systemic adverse effects. In general, they are believed to be well tolerated and appropriate for use as an over-the-counter (OTC) drug. Case Presentation: A 68-year-old woman visited our clinic due to tarry stool. The patient reported multiple episodes of recurrent bleeding from a gastric ulcer for 2 months and was treated with endoscopic hemostatic clipping. The patient disclosed she had been using a large number of diclofenac patches for more than 3 months. The patient was treated conservatively by discontinuation of diclofenac patches and treatment with a proton pump inhibitor and omeprazole. Conclusion: In conclusion, inappropriate use of topical NSAID patches can be a cause of peptic ulcer bleeding. Patients reporting multiple episodes of recurrent bleeding from a gastric ulcer should be questioned, particularly about the use of OTC medications that might include topical NSAID patches

Bile pigments in emergency and critical care medicine

Bile pigments, such as bilirubin and biliverdin, are end products of the heme degradation pathway in mammals and are widely known for their cytotoxic effects. However, recent studies have revealed that they exert cytoprotective effects through antioxidative, anti-inflammatory, and immunosuppressive properties. All these mechanisms are indispensable in the treatment of diseases in the field of emergency and critical care medicine, such as coronary ischemia, stroke, encephalomyelitis, acute lung injury/acute respiratory distress syndrome, mesenteric ischemia, and sepsis. While further research is required before the safe application of bile pigments in the clinical setting, their underlying mechanisms shed light on their utilization as therapeutic agents in the field of emergency and critical care medicine. This article aims to summarize the current understanding of bile pigments and re-evaluate their therapeutic potential in the diseases listed above

Mid-term (30- to 90-day) neurological changes in out-of-hospital cardiac arrest patients: A nationwide retrospective study (the JAAM-OHCA registry)

Objective Few studies have focused on mid/long-term neurological changes in out-of- hospital cardiac arrest (OHCA) survivors. Some studies suggest that there is still a slow, small, progressive improvement in cognitive function and quality of life for this population, even in the mid/long term. However, clinical data focused on mid/long-term outcomes for OHCA patients are still lacking. This study aimed to assess mid-term neurological changes in OHCA patients. We summarized patients' improved or worsened neurological changes between 30 and 90 days. Then we identified the relationship between clinical variables and 30- to 90-day neurological improvement. Methods A retrospective review of data (Jun 2014 - Dec 2017) from a Japanese nationwide OHCA registry was conducted. Inclusion criteria were OHCA patients ≥18 years old. Exclusion criteria were death within 30 days and missing Cerebral Performance Category (CPC) score at 30 and 90 days. We described the distributions of 30-day and 90-day CPC scores as well as the number and portion of patients whose CPC scores improved and worsened between 30 and 90 days. Additionally, factors affecting improved neurological changes over the time period were examined using multivariable logistic regression. Results Of the registry's 34,745 patients, 1868 were analyzed. Favorable neurological outcomes (CPC scores of 1 and 2) were seen in 1020/1868 patients at 90 days. CPC scores at 90 days were: CPC 1: 866 (46%), CPC 2: 154 (8.2%), CPC 3: 224 (12%), and CPC 4: 392 (20%), respectively. A total of 232 patients (CPC 5: 12%) died between 30 and 90 days. In 133 patients (7%), 90-day CPC scores improved compared to their 30-day scores. In 260 patients (14%), 90-day CPC scores worsened compared with their 30-day scores. Application of target temperature management was an independent factor for 30- to 90-day neurological improvement (adjusted odds ratio: 1.69, 95% confidence interval: 1.07–2.68). Conclusions In our nationwide registry, 7% of resuscitated patients had improved neurological changes in the 30- to 90-day period; most of the improvements were CPC scores improving from 2 to 1. Target temperature management was an independent factor associated with CPC improvement over the 30- to 90-day period

Carbon monoxide poisoning during pregnancy treated with hyperbaric oxygen

Acute carbon monoxide (CO) intoxication during pregnancy causes fetal death and teratogenic effects. Hyperbaric oxygen (HBO2) therapy has the potential to improve them. HBO2 therapy should be considered to treat CO intoxication during pregnancy

Retropharyngeal hematoma presenting airway obstruction: A case report

Introduction Blunt neck trauma patients can suffer from an airway emergency and are necessary to careful observation. Presentation of case A 79-year-old man under anticoagulation therapy presented to our hospital three hours after a fall. Shortly after arrival, he developed dyspnea. Oral intubation was attempted, but with no success; therefore, an emergency tracheotomy was performed. Contrast-enhanced computed tomography (CT) and subsequent angiography revealed active bleeding from a branch of the right ascending cervical artery. Subsequently, the right thyrocervical trunk, which is upstream from the ascending cervical artery, was embolized and hemostasis was achieved. He was discharged 52 days after the emergency admission. Discussion This is the first case report of an ascending cervical artery injury due to blunt trauma that resulted in an airway emergency. Contrast-enhanced CT and cervical angiography are useful for confirming the area of injury and size of the hematoma. Half of patients with respiratory distress accompanied by a cervical spine injury require definitive airway management within five hours of the injury and all by 24 h. Neck trauma can lead to fatal airway obstruction and careful monitoring is warranted to detect any signs of impeding respiratory obstruction. Conclusion All emergency physicians need to keep their airway management skills updated in order to perform reliably and rapidly in difficult and urgent situations

Prehospital emergency life-saving technicians promote the survival of trauma patients: A retrospective cohort study

Objective Appropriate decisions by medical technicians at a trauma scene may influence a patient's prognosis. Emergency life-saving technicians (ELSTs) are certified specialists trained with the knowledge to provide advanced techniques for prehospital emergency care in Japan. However, the benefit of treatment by ELSTs compared to basic emergency medical technicians (BEMTs) remains unclear. The aim of this study is to determine whether treatment by ELSTs improves outcomes for trauma patients. Methods We retrospectively reviewed the Japan Trauma Data Bank for the years 2004 to 2017. Patients transferred to the hospital directly from the trauma scene and at least 16 years old were included in this study. The following criteria were used to exclude patients; presence of burns, untreatable severe traumas, unknown ELST attendance, and missing prognosis. We compared two groups (ELST group: patients transported by emergency medical services (EMS) with the presence of at least one ELST; BEMT group: patients transported only by BEMTs). Primary outcome was survival to discharge. Secondary outcomes were the need of definitive treatments defined by surgical intervention, intravascular radiology and blood transfusion at the receiving hospital within 24 h. A multivariable logistic regression model was used to calculate odds ratio (OR) and confidence intervals (CI) adjusted by age, sex, revised trauma score, and Injury severity score (ISS). Results Overall survival to discharge did not improve significantly (adjusted OR 1.13, 95% CI 0.99–1.30) with ELST intervention. In-hospital blood transfusion was more frequently required in the ELST group (adjusted OR 1.10, 95% CI 1.01–1.20). Emergency interventions (adjusted OR 1.03, 95% CI 0.97–1.09) were not different between the groups. In stratified analysis, the benefit of ELST attendance for survival was observed among patients with ISS Conclusions Dispatch systems with ELST should be considered for trauma transports, which may benefit elderly or moderate severity trauma groups, with shorter transportation time conditions

Right Hemiplegia Following Acute Carbon Monoxide Poisoning

Acute carbon monoxide (CO) poisoning remains a common cause of poison-related death and influences neurological function. An 83-year-old female was transferred to our emergency unit due to hypertension with dizziness, headache, and right hemiplegia. There was no radiographic evidence of ischemic stroke. The family members reported that the patient may have been exposed to CO by briquettes burned inside a closed room. High flow oxygen therapy was given for suspected CO intoxication and her symptoms quickly improved. Although we do not have clear evidence, we presume that hemiplegia in our patient was caused by CO intoxication, based on rapid recovery with oxygen therapy, carboxyhemoglobin (COHb) level elevation (3.0%), polycythemia, and neuroimaging. Despite the hematogenous effects of CO, paralysis appeared to be more severe on her right side than on her left side. MRI and blood tests helped to support CO as the suspected cause of her hemiplegia. This case reconfirms the importance of medical interviewing by medical practitioners, even in an emergency setting

Can Blood Ammonia Level, Prehospital Time, and Return of Spontaneous Circulation Predict Neurological Outcomes of Out-of-Hospital Cardiac Arrest Patients? A Nationwide, Retrospective Cohort Study

Background: This study aimed to test if blood ammonia levels at hospital arrival, considering prehospital time and the patient's condition (whether return of spontaneous circulation [ROSC] was achieved at hospital arrival), can predict neurological outcomes after out-of-hospital cardiac arrest (OHCA). Methods: This was a retrospective cohort study on data from a nationwide OHCA registry in Japan. Patients over 17 years old and whose blood ammonia levels had been recorded were included. The primary outcome was favorable neurological outcome at 30 days after OHCA. Blood ammonia levels, prehospital time, and the combination of the two were evaluated using the receiver operating characteristic curve to predict favorable outcomes. Then, cut-off blood ammonia values were determined based on whether ROSC was achieved at hospital arrival. Results: Blood ammonia levels alone were sufficient to predict favorable outcomes. The overall cut-off ammonia value for favorable outcomes was 138 mu g/dL; values were different for patients with ROSC (96.5 mu g/dL) and those without ROSC (156 mu g/dL) at hospital arrival. Conclusions: Our results using patient data from a large OHCA registry showed that blood ammonia levels at hospital arrival can predict neurological outcomes, with different cut-off values for patients with or without ROSC at hospital arrival

Pediatric airway compromise due to thyroid storm associated with influenza A infection: A case report

Thyroid storm is a potentially fatal intensification of thyrotoxicosis normally marked by tachycardia, hyperthermia, impaired mental status, and severe agitation. It can be initiated by numerous causes. Failure to promptly diagnose the condition may lead to high mortality. Early diagnosis and treatment of thyroid storm are essential to prevent further life-threatening complications. A 10-year-old girl was admitted to our emergency center for intensive care. The patient presented tachypnea with stridor, paradoxical abdominal breathing, and “barking” cough. The patient was diagnosed as upper airway obstruction complicated by thyroid storm associated with influenza infection. Following immediate airway management, the patient was administered a short-acting beta-blocker, hydrocortisone, thiamazole, and saturated solution of potassium iodide was initiated. The patient was extubated on day 8 and transferred to a local hospital on day 11 without adverse complications. When examining patients with influenza infection, emergency doctors should be more attentive not to miss other critical diagnoses. The present case was initially diagnosed as croup due to influenza infection. Sharing our experience may help emergency physicians treat similar cases of pediatric airway compromise due to thyroid storm
