BACKGROUND Meningococcal meningitis is rare in Japan; however, when outbreaks do occur, they predominantly involve domestically infected cases rather than those contracted overseas. CASE REPORT A Japanese man with diabetes in his 50s experienced fever and loss of consciousness, with no history of international travel. In our hospital, gram-negative diplococci were detected in the cerebrospinal fluid (CSF) of the patient by Gram staining, although the rapid agglutination test and cultures of blood and CSF were negative. Multiplex polymerase-chain reaction (PCR) testing returned positive results for meningococcus and parechovirus. Brain MRI revealed a finding of meningitis, but there were no indications of encephalitis. To determine the serotype and genotype, we sent the sample to the National Institute of Infectious Diseases, which identified the serogroup and sequence type (ST) as type B and 2057, respectively. Despite the unknown antimicrobial susceptibility, the patient responded well to empirical treatment with ceftriaxone at 2 g every 12 h, and was discharged with remaining symptoms of dizziness, headache, difficulty hearing in the left ear, and tinnitus in the left ear. CONCLUSIONS In Japan, vaccines covering serogroups A, C, and W/Y are available but not routinely administered. According to epidemiological surveillance reports, serogroup B is the second most common cause of meningococcal meningitis in Japan, yet there is no corresponding vaccine available in the country. This case has prompted a review of the epidemiology of meningococcus in Japan, encompassing strategies for vaccination and hospital infection control to prevent droplet transmission, which includes post-exposure prophylaxis when no prior measures have been implemented.
背景脑膜炎球菌脑膜炎在日本非常罕见,但一旦爆发,主要是国内感染病例,而非海外感染病例。病例报告 一名 50 多岁的日本男性糖尿病患者出现发热和意识丧失,无国际旅行史。在我院,通过革兰氏染色法在患者脑脊液(CSF)中检测到革兰氏阴性双球菌,但快速凝集试验以及血液和脑脊液培养均为阴性。多重聚合酶链反应(PCR)检测结果显示脑膜炎球菌和帕雷奇病毒呈阳性。脑部核磁共振成像显示发现了脑膜炎,但没有脑炎的迹象。为了确定血清型和基因型,我们将样本送往国家传染病研究所,研究所确定血清群和序列类型(ST)分别为 B 型和 2057 型。尽管抗菌药敏感性不明,但患者对头孢曲松(每 12 小时 2 克)的经验性治疗反应良好,出院时仍有头晕、头痛、左耳听力困难和左耳耳鸣等症状。结论 在日本,A、C 和 W/Y 血清群疫苗已经上市,但并未常规接种。根据流行病学监测报告,血清 B 群是日本脑膜炎球菌脑膜炎的第二大常见病因,但日本没有相应的疫苗。这一病例促使人们重新审视日本脑膜炎球菌的流行病学,包括疫苗接种和医院感染控制策略,以防止飞沫传播,其中包括在未采取任何措施的情况下进行暴露后预防。

BACKGROUND Over-the-counter (OTC) supplement use is a very common practice within the United States. Supplements are not tightly regulated by the Food and Drug Administration. There are many case reports involving OTC supplement adverse effects and medication interactions, but there remains minimal clinical research regarding these subjects. Rhabdomyolysis is one interaction and adverse effect frequently documented in case reports among a variety of OTC supplements, although, to date, there is no documentation of rhabdomyolysis occurring from an interaction between the supplement Tribulus terrestris and atorvastatin. CASE REPORT A 71-year-old man presented to the Emergency Department in rhabdomyolysis with a mild transaminitis after taking the over-the-counter supplement Tribulus terrestris while on long-term atorvastatin. His rhabdomyolysis peaked at day 4 after cessation of the Tribulus and atorvastatin and aggressive fluid resuscitation with a normal saline bolus at admission followed by a D5 sodium bicarbonate drip later transitioned to a normal saline drip with subsequent down-trending of the creatinine phosphokinase levels. CONCLUSIONS Tribulus terrestris is an herbal supplement used for erectile dysfunction and energy. Recent research suggests it to be a moderate CYP 3A4 inhibitor that plays a significant role in metabolism of statin and many other commonly prescribed medications. This may put patients at increased risk of developing serious adverse effects, including rhabdomyolysis and drug-induced liver injury. Screening patients for over-the-counter supplement use and educating them on the potential risks of their use is extremely important for inpatient and outpatient healthcare professionals to avoid dangerous medication interactions.

BACKGROUND Amlodipine, a calcium channel blocker, and atenolol, a beta blocker, are commonly used as a fixed drug combination (FDC) to treat hypertension. Intentional or non-intentional overdose of amlodipine-atenolol results in hypotension and myocardial depression with a high risk of mortality. This report describes a 64-year-old man with an overdose of amlodipine-atenolol, presenting as an emergency with hypotension, bradycardia, and severe metabolic acidosis. He was successfully treated with intravenous calcium chloride infusion, hyperinsulinemia euglycemia therapy (HIE), and continuous veno-venous hemodialysis (CVVHD). CASE REPORT A 64-year-old man was diagnosed with essential hypertension 1 week prior to the admission. He had been prescribed 1 FDC tablet of amlodipine and atenolol (5+50 mg) per day; however, he took 1 table of the FDC per day for 3 days and then took 3-4 tablets each day during the next 4 days. He was brought to the hospital with hypotension, bradycardia, and severe metabolic acidosis and was diagnosed with amlodipine-atenolol overdose. He was treated with intravenous calcium chloride infusion, HIE, and CVVHD. His hemodynamics started to improve after administering these therapies for 6 h. Inotropes were gradually tapered off and stopped. He was extubated on day 5 and recovered completely. CONCLUSIONS This report shows the serious effects amlodipine-atenolol overdose and the challenges of emergency patient management. An overdose of FDC of amlodipine and atenolol can cause cardiovascular collapse and severe metabolic acidosis. Timely and aggressive management with intravenous calcium infusion, HIE, and CVVHD is essential.

BACKGROUND Papillary muscle rupture (PMR) is a rare complication of myocardial infarction (MI); experiencing PMR without MI makes it even more uncommon, thereby complicating its diagnosis. Therefore, we report a case of spontaneous PMR to raise awareness of this entity. CASE REPORT A 48-year-old man with type 2 diabetes presented to the Emergency Department (ED) after experiencing sudden shortness of breath that began the day before. He had no history of chest trauma, fever, chills, or ischemic chest pain. His vital signs showed stable blood pressure and mild tachycardia. The patient had hypoxemia that did not respond to use of a non-rebreather mask (oxygen saturation 70%). Upon examination, he had increased respiratory rate, altered sensorium, no lower-limb edema, and his chest auscultation revealed bilateral crackles. Chest radiography showed pulmonary edema. Two electrocardiograms (ECG) showed no signs of ST elevation myocardial infarction (STEMI) or RV strain. The patient was intubated but remained hypoxic despite maximum ventilation settings. Transthoracic echocardiography (TTE) performed immediately thereafter revealed acute severe mitral regurgitation with evidence of PMR. A multidisciplinary team approach was adopted early in this case, which resulted in a positive outcome. Eventually, mitral valve replacement was performed, and the patient was discharged home after 17 days, with a favorable neurological outcome. CONCLUSIONS We report a very rare case of spontaneous PMR in a middle-aged man with no evidence of MI, infective endocarditis, or preceding chest trauma. It shows the importance of adopting an early multidisciplinary team approach and showcases the abilities of emergency medicine physicians in early recognition.

BACKGROUND Crusted scabies is a severe skin infection resulting from hyper-infestation with the obligate parasite Sarcoptes scabiei var. hominis. In contrast to classic scabies, crusted scabies may involve as many as hundreds to millions of mites. Importantly, this condition is associated with a mortality rate of 60% in 5 years, and is more likely to develop in immunosuppressed hosts, presumably due to an impaired T-cell response against the mite. CASE REPORT We present a case of crusted scabies in a 13-year-old girl during her early post-liver transplant period receiving immunosuppression successfully treated with topical 5% permethrin. She had pruritic erythematous papules, confirmed as scabies through skin scraping. The challenge of misdiagnosis during the initial presentation is noteworthy, given atypical manifestations and more common differentials. To our knowledge, only 2 cases of crusted scabies in pediatric solid-organ transplant recipients have been reported. Despite the absence of guidelines for pediatric solid-organ transplant recipients, urgent treatment is required due to the high associated mortality rates. In our case, early treatment proved successful without any secondary bacterial infections or clinical evidence of relapse during a 6-month follow-up. CONCLUSIONS We report a case of scabies in a pediatric liver transplant recipient that was successfully treated. It is crucial to consider the diagnosis of scabies given the associated morbidity and the risk of secondary bacterial infections among other more common differentials. Notably, the response to standard anti-scabies treatment may lead to resolution without relapse in pediatric solid-organ transplant recipients.

BACKGROUND Immune checkpoint inhibitors (ICIs) have been linked to various immune-related adverse events, including pneumonitis, necessitating early recognition and potential treatment discontinuation. Acute eosinophilic pneumonia (AEP) induced by ICIs, particularly with no reported cases involving anti-TIGIT therapy, is rare. This report describes a case of AEP following treatment with pembrolizumab and anti-TIGIT therapy. CASE REPORT A 46-year-old woman with lung adenoid cystic carcinoma and chronic hypoxemic respiratory failure on long-term oxygen therapy presented with fever, cough, and shortness of breath. She underwent left pneumonectomy and radiation therapy at diagnosis 9 years earlier. She was participating in a clinical trial using pembrolizumab and anti-TIGIT EOS-448, due to cancer progression. After starting therapy, she developed stable peripheral eosinophilia and a skin rash, suggestive of a drug reaction. On admission, she was in acute-on-chronic hypoxemic respiratory failure, febrile, with an elevated eosinophil count and new multifocal infiltrates in the right lung. Despite broad antibiotics coverage for pneumonia, she developed worsening respiratory symptoms and eosinophilia. She was then empirically started on intravenous methylprednisolone for acute eosinophilic pneumonia without confirmatory bronchoscopy as she was at high risk with her previous pneumonectomy. She subsequently had rapid improvement in her symptoms. CONCLUSIONS AEP should be considered in patients treated with ICIs who develop immune-related adverse effects. Although bronchoscopy findings are part of AEP's diagnostic criteria, this case underscores the importance of clinical judgment in the prompt initiation of steroids, even without confirmatory bronchoscopy, in rapidly progressing cases. The role of anti-TIGIT therapy in this context remains uncertain.
