    Abstract Campylobacter spp. is a widely recognized pathogen accountable for acute enteritis, frequently linked to sepsis, primarily attributed to C. jejuni. Instances of Campylobacter-induced cholecystitis are infrequent, with only a limited number of documented case reports. Acute cholecystitis has been sporadically documented to induce electrocardiographic alterations, occasionally simulating an acute coronary syndrome (ACS). Herein, we present an instance of cholecystitis induced by C. jejuni, posing a challenge in its differentiation from ACS due to electrocardiographic modifications. An 85-year-old Japanese male presented to our hospital with a complaint of chest discomfort lasting one hour. His medical history included hypertension, dyslipidemia, and effort angina pectoris, with a prior percutaneous coronary intervention. The chest discomfort, accompanied by pain and pressure, raised uncertainty about its similarity to a previous angina episode. Vital signs were in the normal range. Physical examination revealed no abnormal heart or lung sounds. Electrocardiography indicated a right bundle branch block and new ST-segment elevation in V2-3. Echocardiography, chest X-rays, and blood tests showed no abnormalities. Emergency coronary angiography revealed no stenosis. Post-angiography, chest discomfort persisted, and the patient developed fever and chills. Contrast-enhanced CT revealed gallbladder lithiasis, prompting suspicion of sepsis. C. jejuni was detected, and antimicrobial therapy resolved symptoms.

    Abstract A 59-year-old male dialysis patient with a history of coronary artery bypass graft surgery underwent percutaneous coronary intervention of a right coronary artery with a severely calcified lesion. While debulking calcification using a Rotablator, the driveshaft was suddenly fractured. We attempted to move a child-in-mother catheter closer and across a second floppy wire and we dilated a 2.0-mm noncompliant balloon to trap the driveshaft, which we then removed, and restarted the intervention.

    Abstract A 65-year-old Japanese man without medical history presented with sudden onset lower abdominal pain to our emergency department. Contrast-enhanced computed tomography (CT) revealed dissections of the inferior mesenteric artery and left renal artery with false lumen thrombosis without aortic dissection. He was immediately hospitalized, and conservative treatment was administered. However, on the third-day post-onset, the patient reported severe upper abdominal pain and contrast-enhanced CT showed a new superior mesenteric artery dissection. He continued to receive conservative treatment, and his symptoms improved. He was discharged after ten days of hospitalization.

    Abstract BACKGROUND Heart failure is caused by coronary artery disease, valvular disease, and arrhythmias and is highly treatable with recent technology. However, the incidence of syphilis is increasing worldwide. This case report describes tertiary cardiovascular syphilis, accompanied by aortic regurgitation, syphilitic aortitis complicated by thrombus of the ascending aorta, and coronary artery occlusion, requiring percutaneous coronary artery intervention. CASE REPORT A 51-year-old Japanese man with no significant medical history was admitted to the hospital for worsening shortness of breath on exertion. On physical examination, there was no edema in either lower leg. Chest X-rays showed an enlarged heart and pulmonary congestion, and echocardiography showed a left ventricular ejection fraction of 18%, with full circumferential wall motion impairment. Heart failure was diagnosed, and the patient was found to have severe coronary artery disease and aortic regurgitation. He underwent percutaneous coronary intervention (PCI) for his coronary artery occlusion and was treated with medications for heart failure. Two months later, his condition improved, and PCI was performed for the revascularization of the remaining coronary artery. After PCI was completed, the patient was evaluated for vasculitis. The aortic wall lesion was likely a result of non-active syphilitic aortitis, and the results of serological tests of syphilis were positive. Therefore, we concluded that the diagnosis was cardiovascular syphilis. CONCLUSIONS This case report has highlighted the need for clinicians to be aware of the cardiovascular findings in syphilis, including syphilitic aortitis, particularly at this time, when the global incidence of syphilis is increasing.

    Abstract Hypercortisolism is a risk factor for adverse cardiovascular and cerebrovascular outcomes, including hypertension, hyperglycemia, and dyslipidemia. It has been suggested that cardiovascular risk increases with increasing steroid use in patients taking oral steroids as immunosuppressive drugs. Cardiomyopathy is often reported to occur concomitantly in patients with Cushing's syndrome. Reports of cases of long-term high-dose glucocorticoid ingestion and concomitant cardiomyopathy are rare. We report a case of cardiomyopathy in a 63-year-old Japanese man. He had refractory bronchial asthma and had been on prednisolone ≥15 mg/day equivalent for >20 years. Echocardiography showed severe left ventricular dilatation, left ventricular systolic dysfunction, and mitral regurgitation. Since other secondary cardiomyopathies were excluded, a diagnosis of glucocorticoid cardiomyopathy was made, cardioprotective drugs were introduced, and the steroid dose was reduced during hospitalization. Four months after the patient's discharge, echocardiography showed normalization of left ventricular systolic function.

    Abstract A 27-year-old Japanese woman with a history of depression and an eating disorder presented to our emergency department with a chief complaint of generalized weakness. Electrocardiography showed prominent QT prolongation with multiple ventricular contractions. Chest X-ray plain computed tomography revealed pulmonary edema. Echocardiography showed decreased left ventricular systolic function. Suspecting acute myocarditis, we performed a myocardial biopsy from the right ventricular septum. The biopsy histology revealed extensive myocardial fibrosis and a very mild inflammatory cell infiltrate. In an additional detailed medical interview, the patient admitted that she had consumed three bottles of a first-aid liquid containing naphazoline approximately ~12 h before her presentation, in a suicide attempt. Her QTc and left ventricular ejection fraction improved during hospitalization.
    Learning objective: Acute drug intoxication can cause QT prolongation and ventricular arrhythmias, cardiomyopathy, and pulmonary edema. When acute QT prolongation, myocardial damage, and pulmonary edema are seen (suggesting acute myocarditis), naphazoline intoxication should be investigated in the differential diagnosis.
