    Newly introduced heat-not-burn or electronic cigarettes can cause lethal nicotine intoxication if ingested at higher doses. Although routine gastric lavage is not recommended, it should be considered if the amount of intoxicant is lethal. A 59-year-old man with a history of depression was brought to our emergency department after intentional ingestion of 8 heat-not-burn cigarettes, which were estimated to contain a total of 100 mg of nicotine. Abdominal computed tomography confirmed the gastric contents, detecting multiple stick-like and rod-shaped high-density structures. Gastric lavage was performed to minimize absorption of the potentially lethal nicotine dose. The patient exhibited only mild gastrointestinal symptoms. Emergency physicians should be aware of this novel heat-not-burn cigarette and its toxicity

    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

    A Rare Case of Pelvic Abscess Due to Spontaneous Non-traumatic Bladder Rupture

    Spontaneous bladder rupture is an uncommon and life-threatening urological emergency, and early diagnosis is often challenging. Herein, we report a case of intraperitoneal bladder rupture in an 81-year-old male with neurogenic bladder-the case of intraperitoneal bladder rupture required late laparotomy for pelvic abscess following initial conservative treatment. An eighty-one-year-old male presented to our emergency department with deterioration of consciousness, fever, and hematuria. He denied previous trauma history and had been treated for neurogenic bladder. Physical examination revealed signs of tenderness in the abdomen. A diagnosis of bladder rupture was made based on laboratory examination indicating renal failure and radiological imaging showing urinary ascites. Conservative management with a Foley catheter and antibiotics (meropenem administered 1 g/day) was initiated. On day seven after admission, the patient complained of abdominal pain and fever, and a diagnosis of pelvic abscess based on contrast-enhanced computed tomography and septic peritonitis was made. An emergency exploratory laparotomy for peritoneal drainage was performed. The postoperative course was uneventful, and the patient was discharged on day 29 after admission. Urinary bladder rupture should always be considered as a differential diagnosis in patients presenting with free fluid in the abdomen, peritonitis, reduced urine output, and hematuria. Clinicians should be aware that secondary bacterial peritonitis can occur as a major complication of a ruptured urinary bladder

    Geriatric trauma prognosis trends over 10 years: analysis of a nationwide trauma registry

    Purpose With Japan's population rapidly skewing toward aging, the number of geriatric trauma patients is expected to increase. Since we need to continue to improve the quality of geriatric trauma patient care, this study aimed to evaluate in-hospital mortality trends among geriatric trauma patients in Japan over a recent 10-year period. Methods This was a retrospective cohort study of data from a Japanese nationwide trauma registry (the Japan National Trauma Data Bank) on patients admitted between January 1, 2008 and December 31, 2017. Geriatric patients were defined as those 65 years old and older. The primary outcome was to clarify in-hospital mortality trends and changes over these 10 years. Results We identified 265 268 eligible trauma patients. Excluding those under 65 years old and those with inadequate or unknown age data, missing prognosis, out-of-hospital cardiac arrest, and burns, 107 766 patients were enrolled in this study. The total trauma patient in-hospital mortality trend was evaluated using the Cochran-Armitage test and showed a significant decrease (p= 16) showed a significant decreasing trend (p<0.001) over time (from 26.1% to 14.5%), less-severe trauma patients (ISS <16) did not (p=0.41) (from 2.7% to 2.1%). Mixed logistic regression analysis showed that the number of year patients stayed in the hospital was significantly associated with mortality. Conclusions While recognizing the limitations of the current analysis, our data demonstrated that prognoses for severe trauma patients over 65 years old improved dramatically over these 10 years, especially in those with severe trauma

    Application of a First Impression Triage in the Japan Railway West Disaster

    On April 25, 2005, a Japanese express train derailed into a building, resulting in 107 deaths and 549 injuries. We used “First Impression Triage (FIT)”, our new triage strategy based on general inspection and palpation without counting pulse/respiratory rates, and determined the feasibility of FIT in the chaotic situation of treating a large number of injured people in a brief time period. The subjects included 39 patients who required hospitalization among 113 victims transferred to our hospital. After initial assessment with FIT by an emergency physician, patients were retrospectively reassessed with the preexisting the modified Simple Triage and Rapid Treatment (START) methodology, based on Injury Severity Score, probability of survival, and ICU stay. FIT resulted in shorter waiting time for triage. FIT designations comprised 11 red (immediate), 28 yellow (delayed), while START assigned six to red and 32 to yellow. There were no statistical differences between FIT and START in the accuracy rate calculated by means of probability of survival and ICU stay. Overall validity and reliability of FIT determined by outcome assessment were similar to those of START. FIT would be a simple and accurate technique to quickly triage a large number of patients

    A Hypothesis on Biological Protection from Space Radiation Through the Use of New Therapeutic Gases

    Radiation exposure to astronauts could be a significant obstacle for long duration manned space exploration because of current uncertainties regarding the extent of biological effects. Furthermore, concepts for protective shielding also pose a technically challenging issue due to the nature of cosmic radiation and current mass and power constraints with modern exploration technology. The concern regarding exposure to cosmic radiation is the biological damage it induces. As damage is associated with increased oxidative stress, it is important and would be enabling to mitigate and/or prevent oxidative stress prior to the development of clinical symptoms and disease. This paper hypothesizes a "systems biology" approach in which a combination of chemical and biological mitigation techniques are used conjunctively. It proposes using new, therapeutic, medical gases as both chemical radioprotectors for radical scavenging and biological signaling molecules for management of the body s response to exposure. From reviewing radiochemistry of water, biological effects of CO, H2, NO, and H2S gas, and mechanisms of radiation biology, it is concluded that this approach may have great therapeutic potential for radiation exposure. Furthermore, it also appears to have similar potential for curtailing the pathogenesis of other diseases in which oxidative stress has been implicated including, cardiovascular disease, cancer, chronic inflammatory disease, hypertension, ischemia/reperfusion injury, acute respiratory distress syndrome, parkinson s and alzheimer s disease, cataracts, and agin
