Successful Resuscitation Following Intraoperative Acute Pulmonary Embolism With a Focus on Control of Bleeding After Thrombolytic Therapy: A Case Report.

Acute pulmonary embolism is a serious perioperative complication. Current guidelines focus on hemodynamic stabilization and rapid restoration of pulmonary artery blood flow. However, various complications, most notably bleeding, are associated with treatment of the embolism.

Diagnostic accuracy of late iodine enhancement on cardiac computed tomography with a denoise filter for the evaluation of myocardial infarction.

We evaluated the image quality and diagnostic performance of late iodine enhancement (LIE) in dual-source computed tomography (DSCT) with low kilo-voltage peak (kVp) images and a denoise filter for the detection of acute myocardial infarction (AMI) in comparison with late gadolinium enhancement (LGE) magnetic resonance imaging (MRI). The Hospital Ethics Committee approved the study protocol. Before discharge, 19 patients who received percutaneous coronary intervention after AMI underwent DSCT and 1.

Adenosine triphosphate stress dual-source computed tomography to identify myocardial ischemia: comparison with invasive coronary angiography.

Purpose: The purpose of this study was to investigate the utility incremental diagnostic value of combined assessment with coronary CT angiography (CCTA) and myocardial CT perfusion imaging (CTP) using dual-energy technology with an Adenosine Triphosphate (ATP) load technique.

Materials And Methods: Twenty-one patients underwent ATP-provocation dual-energy CT and CAG. We compared the diagnostic accuracy with CAG, for ischemic region due coronary stenosis by CCTA alone and CCTA combined with CTP (Combined CCTA/CTP).

Functional assessment of coronary artery flow using adenosine stress dual-energy CT: a preliminary study.

We attempted to assess coronary artery flow using adenosine-stress and dual-energy mode with dual-source CT (DE-CT). Data of 18 patients with suspected coronary arteries disease who had undergone cardiac DE-CT were retrospectively analyzed. The patients were divided into two groups: 10 patients who performed adenosine stress CT, and 8 patients who performed rest CT as controls.

[Evaluation of efficacy and safety of adjuvant analgesics for peripheral neuropathy induced by cancer chemotherapy in digestive cancer patients-a pilot study].

After 1990's, the development of new generation anti-cancer agents produced encouraging improvement of prognosis in inoperable or relapsed stomach cancer and colorectal cancer. However, non-hematological toxicity, such as peripheral neuropathies, become a new dose-limiting toxicity. In several new generation drugs, measures for controlling peripheral neuropathy had not been established besides dose modification or schedule modification.

A ruptured large extraluminal ileal gastrointestinal stromal tumor causing hemoperitoneum.

We describe an 87-year-old woman with a large ileal gastrointestinal stromal tumor (GIST) causing hemoperitoneum. A CT scan demonstrated a large heterogeneous mass measuring about 13 cm multiply 11 cm in the pelvis and hemoperitoneum, with a non-uniform enhancement pattern. The mass was diagnosed as a GIST originating from the gastrointestinal tract.

Evaluation of video-assisted thoracoscopic surgery for pulmonary metastases: 11-years of experience.

Background: Although video-assisted thoracoscopic surgery (VATS) has been applied to pulmonary resection for pulmonary metastases, the clinical validity of this approach remains controversial. The purpose of this study was to evaluate the validity and problems of VATS for pulmonary metastasectomy.

Methods: From January 1993 to December 2003, VATS for pulmonary metastasectomy was performed in 53 resections for 48 patients at our institution.

Ileal schwannoma developing into ileocolic intussusception.

Intussusception is rare in adults. We describe a 47-year-old man with ileal schwannoma that led to ileocolic intussusception. Abdominal ultrasonography, abdominal CT scan and barium enema confirmed an ileal tumor.

Systemic versus coronary levels of inflammation in acute coronary syndromes.

To address a possible link between systemic and coronary inflammation in the setting of acute coronary syndromes, the authors examined both levels of 3 inflammatory mediators such as high sensitive C-reactive protein (hs-CRP), interleukin (IL)-6, and matrix metalloproteinase (MMP)-9 in patients with the early phase of acute myocardial infarction (AMI). In total, 20 patients with AMI showing minimal elevation of cardiac enzymes were studied. Before angioplasty, peripheral blood and culprit coronary thrombus were sampled to compare systemic and coronary levels of hs-CRP, IL-6, and MMP-9.

Prevention of positive coronary artery remodeling with statin therapy in patients with coronary artery diseases.

Since positive coronary artery remodeling with large plaque burden is associated with subsequent coronary events, the authors tested their hypothesis that secondary prevention of coronary events by a statin may be associated with inhibition of the process of positive coronary artery remodeling in underlying coronary atherosclerotic lesions in patients with coronary artery diseases. They evaluated the intravascular ultrasound imaging in angiographically normal coronary lesions at baseline and after 6 months of therapy in 64 patients with coronary artery diseases. External elastic membrane area was defined as the vessel area, and the difference between the vessel and lumen area was calculated as plaque area.

Two cases with long-term disease-free survival after resection and radiotherapy for solitary brain metastasis from breast cancer with extensive nodal metastases.

Two rare cases, each with a solitary brain metastasis from breast cancer with extensive nodal metastases as the first site of distant metastasis, were locally treated with surgery and irradiation. The outcome of the two treated cases indicated an excellent and non-recurrent post-therapeutic survival period of more than 3 and 8 years, respectively. In a 50-year-old woman (Case 1), a solitary brain metastasis was found to have developed after standard radical mastectomy and adjuvant chemotherapy with doxorubicin and tegafur-uracil (UFT) and hormonal therapy with tamoxifen for left breast cancer.

Objective radiologic analysis of ground-glass opacity aimed at curative limited resection for small peripheral non-small cell lung cancer.

Objective: The aim of this study was to evaluate the efficacy of the objective radiologic analysis of high-resolution computed tomographic images of small peripheral non-small cell lung cancer and to select the candidates for curative limited resection.

Cardiac sympathetic nerve activity can detect congestive heart failure sensitively in patients with hypertrophic cardiomyopathy.

Study Objectives: Cardiac sympathetic nerve dysfunction is related to poor clinical outcome in patients with several different heart diseases. However, it is not clear whether cardiac sympathetic nerve activity is useful for predicting the onset of congestive heart failure (CHF) in patients with hypertrophic cardiomyopathy (HCM). The aim of this study was to examine the prognostic value of performing (123)I-labeled metaiodobenzylguanidine (MIBG) scintigraphy in patients with HCM in comparison with other conventional prognostic variables.

[Cardiac tamponade with paroxysmal atrial flutter controlled by antituberculous therapy].

We report a rare and unique case of possible extrapulmonary tuberculosis in an 83-year-old man who had cardiac tamponade and paroxysmal atrial flutter. The patient was admitted to our hospital because of syncope. The cardiac tamponade and paroxysmal atrial flutter were treated by pericardiocentesis and drainage of bloody pericardial fluid.

Expression of cyclooxygenase-2, Fas and Fas ligand in pulmonary adenocarcinoma and atypical adenomatous hyperplasia.

Background: Atypical adenomatous hyperplasia (AAH) has been reported to be a precancerous lesion of pulmonary adenocarcinoma. Cyclooxygenase-2 (COX-2), Fas and Fas ligand (FasL) are believed to be involved in the pathogenesis and progression of cancer.

Patients And Methods: We examined the expression of COX-2, Fas and FasL in 31 tissue specimens of adenocarcinoma and 9 of AAH using an immunohistochemical method.

Prospective study of thoracoscopic limited resection for ground-glass opacity selected by computed tomography.

Background: With recent advances in low-dose helical computed tomography (CT), detection of ground-glass opacity (GGO) has increased. The aim of this study was to correlate high-resolution CT (HRCT) findings with pathologic features and to evaluate the efficacy of thoracoscopic limited resection for focal GGO, which were selected based on HRCT findings.

Methods: Focal GGO lesions were classified into two subtypes based on HRCT findings: pure type and mixed type.

Effect of the addition of a beta-blocker on left ventricular remodeling and prognosis in patients with dilated cardiomyopathy treated with angiotensin-converting enzyme inhibitor.

To examine the effect of the addition of a beta-blocker in the treatment of chronic heart failure due to dilated cardiomyopathy, we compared the change of left ventricular remodeling and the prognosis between patients treated with angiotensin-converting enzyme inhibitors and patients who had beta-blockers added to angiotensin-converting enzyme inhibitors. Fifty-seven patients were treated with an angiotensin-converting enzyme inhibitor in addition to combination therapy with furosemide, spironolactone and digoxin. In 60 patients, a beta-blocker was administered in addition to combination therapy with furosemide, spironolactone, digoxin and an angiotensin-converting enzyme inhibitor.

[Beneficial effect of cibenzoline in a patient with hypertrophic obstructive cardiomyopathy complicated with idiopathic interstitial pneumonia].

A 72-year-old woman who had idiopathic interstitial pneumonia was admitted due to general fatigue. Echocardiography revealed asymmetric septal hypertrophy and systolic anterior movement of the mitral valve. In addition, Doppler echocardiography revealed a pressure gradient of 52 mmHg in the left ventricular outflow tract.

Unsuspected primary pulmonary malignant lymphoma.

A 70-year-old man referred for treatment of a left lower lung tumor was shown in chest computed tomography to have a homogeneous round tumor 45 mm in diameter with an enhanced thin wall in the lower lobe of the left lung. No specific finding was seen in material obtained by transbronchial and computed tomography (CT)-guided lung tissue biopsy, so the presumptive diagnosis was a lung abscess. Despite antibiotics administered for 2 weeks, radiography showed the tumor had grown, necessitating left lower lobectomy.

Comparison of treatment effects of bevantolol and metoprolol on cardiac function and natriuretic peptides in patients with dilated cardiomyopathy.

This study was designed to compare the efficacy of bevantolol, a beta(1)-selective blocker with alpha-blockade and vasodilating activity, with that of metoprolol, a beta(1)-selective receptor blocker, for the treatment of idiopathic dilated cardiomyopathy (DCM). Forty-one patients with DCM were enrolled to receive either bevantolol or metoprolol in addition to the standard therapy for DCM. They were classified into two groups: 16 patients were treated with bevantolol and 25 were treated with metoprolol.

Attenuation of biventricular pressure gradients by cibenzo-line in an 18-year-old patient with hypertrophic obstructive cardiomyopathy.

An 18-year-old male patient with biventricular hypertrophic obstructive cardiomyopathy (HOCM) had successful reduction of the pressure gradients by cibenzoline. At 11 months after birth, he was first diagnosed with cardiac murmurs and by the age of 5 years, he was diagnosed with subpulmonic infundibular stenosis with a pressure gradient of 10 mmHg by cardiac catheterization. At the age of 14, re-catherterization revealed hypertrophic cardiomyopathy with isolated obstruction of the right ventricular outflow tract, with a pressure gradient of 70 mmHg, but no obstruction in the left ventricle.
