Evaluation of novel indices of walking performance taking oxygen desaturation into account during six-minute walk test in cardiovascular disease patients.

In pulmonary disease patients since oxygen desaturation during 6-min walk test (6MWT) affects walk distance (6MWD), some novel indices such as desaturation/distance ratio [DDR, oxygen desaturation area (DAO)/6MWD] and distance-saturation product [DSP, 6MWD × minimum peripheral oxygen saturation (SpO)] are evaluated. However, there has been no study examining these indices that consider exercise-induced desaturation (EID) in patients with cardiovascular disease. In 94 cardiovascular disease patients without pulmonary complications, 6MWT and echocardiography were performed at the entry of cardiac rehabilitation.

An automated screening model for aortic emergencies using convolutional neural networks and cropped computed tomography angiography images of the aorta.

Purpose: Patients with aortic emergencies, such as aortic dissection and rupture, are at risk of rapid deterioration, necessitating prompt diagnosis. This study introduces a novel automated screening model for computed tomography angiography (CTA) of patients with aortic emergencies, utilizing deep convolutional neural network (DCNN) algorithms.

Methods: Our model (Model A) initially predicted the positions of the aorta in the original axial CTA images and extracted the sections containing the aorta from these images.

Renoprotective effect of chronic treatment with sodium-glucose cotransporter 2 inhibitors and its associated factors in Japanese patients with chronic heart failure and diabetes.

Background: Recent clinical trials have shown that sodium-glucose cotransporter 2 (SGLT2) inhibitors have beneficial effects on renal function in heart failure patients. This study confirmed the renoprotective effect of treatment with SGLT2 inhibitors in Japanese patients with chronic heart failure and diabetes and further investigated what cardiac/hemodynamic and noncardiac factors are involved in its effect.

Methods: Eligible 50 outpatients with chronic heart failure and type-2 diabetes mellitus chronically taking SGLT2 inhibitors were enrolled.

Cardiac metastasis of lung cancer presented as mimicking ST-elevation myocardial infarction with reciprocal electrocardiographic changes.

Unlabelled: We report the case of a patient with metastatic cardiac tumor who presented with chest pain and electrocardiographic changes mimicking acute inferior myocardial infarction. An 84-year-old man who had undergone lung cancer surgery one year earlier was referred to emergency outpatient visit because of chest pain. His 12-lead electrocardiography (ECG) showed ST-segment elevation in the inferior leads with reciprocal ST-segment depression in the precordial and lateral leads, which was initially interpreted as inferior acute myocardial infarction.

Achilles tendon thickness is associated with coronary lesion severity in acute coronary syndrome patients without familial hypercholesterolemia.

Background: Thickening of Achilles tendon (≥9 mm on radiography) is one of the diagnostic criteria for familial hypercholesterolemia (FH). Since FH is associated with premature coronary artery disease (CAD) including acute coronary syndrome (ACS), measurement of Achilles tendon thickness (ATT) is important for early diagnosis of FH. However, clinical significance of mild thickening of Achilles tendon in non-FH patients with CAD is unclear.

Patient with penile metastasis from prostate cancer and survival over 5 years: A case report with longitudinal evaluation using computed tomography and magnetic resonance imaging.

Penile metastasis of malignant tumors is a very rare condition, often occurring as a part of systemic metastases, and is therefore associated with a poor prognosis. Although there have been reports of magnetic resonance imaging findings of penile metastasis, longitudinal imaging changes have not been presented previously. We report a case of a 80-year-old male patient with penile metastasis from prostate adenocarcinoma.

Long-term administration of tolvaptan ameliorates annual decline in estimated glomerular filtration rate in outpatients with chronic heart failure.

Protective effects of tolvaptan against worsening renal function in acute heart failure have been shown. However, long-term effects of its agent on renal function remain to be elucidated. The present study investigated retrospectively whether long-term treatment with tolvaptan exerts renoprotective effects in patients with chronic heart failure, by comparing serial changes in estimated glomerular filtration rate (eGFR) for years before and after tolvaptan administration.

Chylothorax treated with targeted sclerotherapy by direct puncture of the lymphatic leakage site.

We report a novel application of targeted sclerotherapy to eradicate high-output chylothorax. The patient underwent thoracic duct embolization; however, cannulation of the thoracic duct failed, and thoracic duct disruption was performed. Leakage continued; therefore, the leakage site in the mediastinum was punctured directly under fluoroscopic guidance and a drainage catheter was inserted, followed by sclerotherapy using OK-432.

[Extreme Obese Patients who Underwent Cardiac Surgery after Preoperative Weight Reduction;Report of Two Cases].

Obesity is a risk factor of postoperative complications. We experienced 2 extremely obese patients:a 32-year-old male with coronary artery disease and a 75-year-old female with aortic valve stenosis. Their initial body weights were 133 kg and 88.

[Portal venous stent placement for variceal hemorrhage in the elevated jejunum caused by portal vein stenosis after pancreatoduodenectomy:a case report].

An 86-year-old male underwent pancreatoduodenectomy with resection and reconstruction of portal vein for pancreatic cancer. He was admitted to our hospital because of severe anemia and dyspnea ten months later. Computed tomography showed varices at the biliary-enteric anastomosis in the elevated jejunum caused by portal venous stenosis, which was suspected as the cause of anemia.

[A Case of Resection of Advanced Pancreatic Adenosquamous Carcinoma in which Multidisciplinary Treatment Was Effective].

A 72-year-old man with general fatigue was referred, and CT and MRI revealed a pancreatic mass with necrosis that was suspected of invading the stomach, splenic artery, celiac artery, liver, and portal vein. Upper gastrointestinal endoscopy showed an extrinsic mass with ulcer formation in the posterior wall of the upper gastric corpus and irregular mucosa in the lower esophagus incidentally. Biopsy showed squamous cell carcinoma from both lesions, leading to the diagnosis of pancreatic adenosquamous carcinoma and early esophageal cancer.

[A Case of Double Cancer of Intrahepatic Cholangiocarcinoma and Gastric Carcinoma with Difficult Diagnosis of the Primary Tumor with Peritoneal Metastasis].

Double cancer of intrahepatic cholangiocarcinoma and gastric cancer is rare. A 62-year-old man underwent gastrectomy for gastric cancer. The pathological findings were tub1>tub2, m, ly0, v0, n0, Stage I A.

[Resection of Adrenal Metastasis after Chemotherapy and Radiation Therapy for a Patient with Stage IV B Hepatocellular Carcinoma].

In the treatment of hepatocellular carcinoma, atypical, off guideline multidisciplinary approaches are sometimes effective. A 70-year-old man was diagnosed with multiple hepatocellular carcinomas, multiple bone metastases, and a right adrenal metastasis. Sunitinib was started and the primary hepatic lesions and bone metastases disappeared.

[Long Term Survival in a Case of Hilar Cholangiocarcinoma Treated with Chemotherapy and Surgery].

A 67-year-old man with elevated hepatobiliary enzymes was referred to our hospital for further examination. Computed tomography indicated hilar cholangiocarcinoma of Bismuth type Ⅳ and revealed invasion of the right hepatic artery and the left portal vein. We diagnosed locally advanced unresectable hilar cholangiocarcinoma, and performed 5 courses of chemotherapy with gemcitabine plus S-1.

[Mixed adenoneuroendocrine carcinoma with multiple liver metastases successfully treated by cetuximab/CPT-11 chemotherapy followed by curative resection - a case report].

A 73-year-old man underwent laparoscopy-assisted partial resection of the rectum to treat rectal cancer diagnosed in September 2011 at a previous hospital. Lymph node dissection was not performed and the vertical margin was positive. When multiple liver tumors were detected 10 months later, the patient was referred to our hospital.

Atresia of the right atrial ostium of the coronary sinus without persistent left superior vena cava.

We present a case of atresia of the right atrial ostium of the coronary sinus. Recognizing this anomaly is important during catheter ablation or cardiac surgery, which could be noninvasively evaluated by multidetector CT.

MR imaging of carcinosarcoma of the liver using Gd-EOB-DTPA.

We present a case of a 69-year-old man with primary hepatic carcinosarcoma who underwent computed tomography that revealed a hypervascular hepatic tumor with local dense calcification. Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging revealed hyperintense lesions in the hepatobiliary phase that indicated hepatocellular carcinoma with bile production. The patient underwent right lobectomy, and the presence of a sarcoma component within the tumor on histopathology confirmed liver carcinosarcoma that included hepatocellular carcinoma.

Spontaneous rupture of the omental artery treated by transcatheter arterial embolization.

Intra-abdominal hemorrhage caused by omental artery rupture is a rare condition. There are few reports on the treatment of omental artery rupture with only transcatheter arterial embolization (TAE). A 27-year-old man presented to our emergency room with upper abdominal pain that suddenly occurred during sleep.

[An autopsied case of a woman with rheumatoid arthritis attacked by multiple cerebral emboli].

A 45-year-old woman, who had had rheumatoid arthritis for 12 years, had three attacks of cerebral embolism over two months and died after the final attack. Intensive clinical laboratory investigations did not disclose any specific origins of emboli, but an autopsy revealed a nodule at the base of the aortic valve which was pathologically proved to be a rheumatoid nodule. The thrombi were present from the distal part of left internal carotid artery up to the proximal part of the left middle cerebral artery.
