Acute Cholecystitis Caused by Campylobacter jejuni Mimicking Acute Coronary Syndrome.

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.

Naphazoline intoxication with transient QT prolongation and acute myocardial injury.

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.

Sequential Multiple Visceral Artery Dissection within a Short Time, without Aortic Dissection.

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.

Tertiary Cardiovascular Syphilis Presenting as Aortic Regurgitation, Aortitis, Thrombus, and Coronary Artery Occlusion, Requiring Percutaneous Coronary Intervention.

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.

Glucocorticoid-Induced Cardiomyopathy Caused by Uncontrollable Asthma.

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.

Acute aortic dissection with left coronary artery obstruction.

If the electrocardiogram shows ST-segment elevation in lead aVR, the complication of aortic dissection must always be assumed.

Successful Bail Out of Rotablator Driveshaft Fracture Due to Severe Calcified Lesion and Proximal Tortuosity.

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.

[A Case of Superficial-Type Gastric Cancer with Metastatic Ovarian Cancer Diagnosed by Exploratory Laparotomy].

Here, we report a case of superficial-type gastric cancer with metastatic ovarian cancer(Krukenberg tumor)diagnosed by exploratory laparotomy. Chemotherapy was initiated at an early stage in this patient. A 43-year-old woman with superficialtype gastric cancer(0-Ⅱb plusⅡa), an ovarian tumor, and a solitary sclerotic bone lesion underwent exploratory laparotomy and bilateral salpingo-oophorectomy. Pathological findings showed that the resected ovarian tumor specimen contained the same type of signet ring cell carcinoma as the biopsy gastric cancer specimen; hence, the patient was diagnosed with superficial- type gastric cancer with metastatic ovarian cancer. She was treated with first-line chemotherapy(capecitabine plus oxaliplatin)15 days after exploratory laparotomy, followed by second-line chemotherapy(ramucirumab plus paclitaxel), thirdline chemotherapy(nivolumab), and fourth-line chemotherapy(irinotecan). Twenty-two months after the start of first-line chemotherapy, she finally died due to bone metastasis.

[Long-Term Survival of a Patient with Metastatic Ovarian Cancer and Local Recurrence of Rectal Cancer].

A 60s woman with upper rectal cancer underwent low anterior resection; the patient was diagnosed with pSSN1, Stage Ⅲa cancer. She received adjuvant therapy with UFT. Three years after the primary resection, metastasis to the right ovary and local recurrence were diagnosed. She was treated with CAPOX plus bevacizumab(Bev), capecitabine, FOLFIRI, and irinotecan plus S-1. Because only the ovarian metastasis increased rapidly, we were able to perform surgery and R0 resection. Two years after resection, local recurrence became apparent, and chemotherapy was reinitiated. After treating the patient with chemotherapy and chemo-radiation therapy for 2 years, R0 resection was performed. Twelve years after primary tumor resection and 9 years after primary resection, we observed recurrence-free survival.

[A Successful Management of Thrombocytopenia Due to Multiple Lung Metastasis of Intrahepatic Cholangiocarcinoma Using Laparoscopic Splenectomy-A Case Report].

We report a case of multiple lung metastasis of intrahepatic cholangiocarcinoma treated with chemotherapy, in which laparoscopic splenectomy was effective for thrombocytopenia. A 74-year-old woman was diagnosed with multiple lung metastasis of intrahepatic cholangiocarcinoma 6 years after partial liver resection(S3). She was undergoing treatment for post-transfusion hepatitis C infection since the age of 46 years and developed thrombocytopenia due to splenomegaly. The previous hospital determined that there was no indication for chemotherapy due to thrombocytopenia. Elective laparoscopic splenectomy resulted in an increase in the platelet count and facilitated the initiation of gemcitabine(GEM)and cisplatin (CDDP)combination chemotherapy. The patient has maintained a good treatment course without interruption due to thrombocytopenia during chemotherapy. In advanced cancer patients with thrombocytopenia complication due to splenomegaly, laparoscopic splenectomy may offer an effective auxiliary means for the safe implementation of chemotherapy.

[A Case of Liver Metastasis of Distal Bile Duct Cancer].

A 60-year-old female visited our hospital due to anorexia and jaundice in March 2016. She underwent pancreatoduodenectomy( PD)and was diagnosed with distal bile duct cancer. The histopathological diagnosis was distal bile duct cancer, tub2, pT3aN1M0, pStage ⅡB. Postoperatively, she received S-1 therapy as adjuvant chemotherapy. One year after surgery, abdomi- nal enhanced CT and EOB-MRI revealed a liver metastasis(S3; 20mm). After 4courses of gemcitabine(GEM)/cisplatin(CDDP) combination therapy, there was no new lesion; thus, we performed partial hepatectomy(S3)in July 2017. The histopathology findings revealed well differentiated adenocarcinoma that was similar to the primary lesion, and the tumor was confirmed as a recurrence of bile duct cancer. She remains alive without second recurrence for 2 years since the tumor resection(about 3 years since PD). Surgical intervention might be beneficial in selected patients with recurrent bile duct cancer.

[Analysis of Early Palliative Care for Patients with Gastric Cancer].

BACKGROUND: Palliative care delivered to cancer patients late in the course of disease are inadequate to improve advance care planning and quality of life; thus, early palliative care is recommended. We retrospectively analyzed early palliative care delivered to patients with gastric cancer. METHOD: Forty-nine gastric cancer patients who underwent surgery and had received interdisciplinary care from the first visit(early palliative care)were assessed for physical and psychosocial symptoms. RESULTS: All patients were followed up continuously by a nurse certified in palliative care support to provide quality patient-centered care from the beginning(advance care planning). Four patients had experienced relapse, and 3 older patients had decided not to receive chemotherapy following their advance care planning. However, all 4 patients were admitted to a palliative care unit without barriers. CONCLUSION: Early palliative care might lead patients to have advance care planning, and a better quality of life.

Efficacy and safety of anticoagulant prophylaxis for prevention of postoperative venous thromboembolism in Japanese patients undergoing laparoscopic colorectal cancer surgery.

AIM: To investigate the efficacy and safety of anticoagulant prophylaxis to prevent postoperative venous thromboembolism (VTE) during laparoscopic colorectal cancer (CRC) surgery, which is unknown in Japanese patients. METHODS: We conducted this randomized controlled trial at nine institutions in Japan from 2011 to 2015. It included 302 eligible patients aged 20 years or older who underwent elective laparoscopic surgery for CRC. Patients were randomly assigned to an intermittent pneumatic compression (IPC) therapy group or to an IPC + anticoagulation therapy group. Anticoagulation therapy comprised fondaparinux or enoxaparin for postoperative VTE prophylaxis. Postoperative VTE was diagnosed based on enhanced multi-detector helical computed tomography. The primary endpoint was VTE incidence, including asymptomatic cases, the secondary endpoint was incidence of major bleeding, and we conducted an intention-to-treat analysis. This study is registered in UMINCTR (UMIN000008435). RESULTS: Postoperative VTE incidence was 5.10% with IPC therapy (n = 157) and 2.76% with IPC + anticoagulant therapy (n = 145; P = .293). We identified no symptomatic VTE cases. The major bleeding rates were 1.27% with IPC alone and 1.38% with the combination (P = .936). The overall bleeding rates were 7.69% for enoxaparin and 13.6% for fondaparinux (P = .500), and there were no bleeding-related deaths. CONCLUSION: Anticoagulant prophylaxis did not reduce the incidence of VTE and the incidence of major bleeding was comparable between the two groups. Usefulness of perioperative anticoagulation was not demonstrated in this study. Pharmacological prophylaxis must be restricted in Japanese patients with higher risk of VTE.

The Risk Factor of Anastomotic Hypoperfusion in Colorectal Surgery.

BACKGROUND: Inadequate blood flow is an important risk factor for anastomotic leakage. Indocyanine green (ICG) fluorescence imaging allows intraoperative assessment of intestinal blood flow. This study determined the risk factor of anastomotic hypoperfusion in colorectal surgery using ICG fluorescence imaging. METHODS: This study included 74 consecutive patients who underwent colorectal surgery between April 2017 and March 2018. ICG was injected intravenously after dividing the mesentery and central vessels along the planned transection line, but before completing the anastomosis. Intraoperative blood flow was evaluated using ICG fluorescence imaging. With regard to the patient-, tumor-, and surgery-related factors, anastomotic perfusion was evaluated based on the changed transection line and prolonged (more than 60 s) perfusion time. RESULTS: Intraoperative ICG fluorescence imaging was performed in all patients, and no adverse events were associated with ICG injection. Based on the perfusion assessment, we changed the transection line in six patients (8.1%). The prolonged perfusion time was observed in nine patients (12.2%). The postoperative course was uneventful in 63 (85.1%) patients, but one patient (1.4%) had postoperative anastomotic leakage. The changed transection line was significantly associated with anticoagulation therapy (P = 0.029). Well-known risk factors, including surgical site, sex, smoking, blood loss, operative time, and preoperative chemoradiotherapy, were not related to the changed transection line. Prolonged ICG perfusion time was not associated with any patient-, tumor-, or surgery-related factors. CONCLUSIONS: The evaluation of intraoperative blood flow using ICG fluorescence imaging may be able to detect anastomotic hypoperfusion, and anticoagulation therapy is a risk factor of anastomotic hypoperfusion in colorectal surgery.

[A Case of Recurrent Gastric Cancer Successfully Treated by S-1 Chemotherapy].

We report a case of recurrent gastric cancer that was successfully treated by S-1 chemotherapy.An 81-year-old woman with advanced gastric cancer[L Less, Type 2, cT4a(SE), cN0H0P0M0, cStageⅡB]underwent distal gastrectomy.Abdominal CT performed 6 months after surgery revealed a low-density area in the liver.She was diagnosed with liver metastasis and started receiving S-1 chemotherapy.The liver metastasis achieved complete response, so S-1 chemotherapy was discontinued 12 months after recurrence.Abdominal CT performed 9 months after the discontinuation of S-1 chemotherapy revealed multiple low-density areas in the liver.She started receiving S-1 chemotherapy again, but S-1 chemotherapy was discontinued because of side effects after 2 courses.The patient died 24 months after receiving S-1 chemotherapy.

[A Case of Liver Metastasis of Intrahepatic Cholangiocarcinoma That Achieved Clinical Complete Response after Gemcitabine and Cisplatin Combination Chemotherapy].

We report a case of liver metastasis of intrahepatic cholangiocarcinoma that achieved clinical complete response after gemcitabine(GEM)and cisplatin(CDDP)combination chemotherapy. The patient was a 69-year-old man who was diagnosed with intrahepatic cholangiocarcinoma with hilar invasion and intrahepatic metastasis(cT4N0M0, Stage ⅣA)and was initially treated with right trisegmentectomy with left portal vein resection, lymph node dissection, and reconstruction of the left portal vein and biliary tract after transhepatic portal vein embolization(PTPE). S-1 was administered continuously as postoperative adjuvant chemotherapy, and the patient showed no signs of recurrence. Three years after the surgery, a CT scan showed LDA 10mm in diameter in the middle area of the remnant liver. We suspected liver metastasis when both serum CA19-9 and DUPAN-2 levels were elevated with the increasing size of LDA; liver biopsy was then performed, and he was diagnosed with liver metastasis of intrahepatic cholangiocarcinoma. After 3 courses of combination chemotherapy containing GEM and CDDP, a CT scan revealed that the liver metastasis reduced in size, and PR was achieved based on the RECIST standard. After 12 courses, the liver metastasis disappeared, and the patient had achieved CR based on the RECIST standard. The patient has received S-1 following the combination chemotherapy and survived for 6 years since initial treatment without any other metastatic lesions.

[A Case of Esophageal Cancer with Aortic Thrombosis That Was Successfully Treated by Aortic Thrombectomy and Video-Assisted Thoracoscopic Esophagectomy].

We report a case of esophageal cancer with aortic thrombosis that occurred during chemotherapy and was successfully treated by aortic thrombectomy and video-assisted thoracoscopic esophagectomy. A 70-year-old man with esophageal cancer( Mt, Type 1c, cT2cN0cM0, cStage Ⅱ)was administered 5-FU plus cisplatin chemotherapy. On day 7 in the first course of the chemotherapy, he experienced abdominal pain. Abdominal CT revealed endo-aortic thrombotic deposits in the aortic arch about 3 cm in diameter. He immediately received heparin at a dose of 20,000 U/day administered intravenously, but the thrombus had not resolved by the next day. He underwent aortic thrombectomy, and warfarin was administered orally after the thrombectomy. He did not experience any difficulties or discomfort related to the thrombus after the thrombectomy. He then underwent video-assisted thoracoscopic esophagectomy and was discharged uneventfully on the 18th postoperative day. Currently, he is under follow-up with no recurrence.
