Malignant fibrous histiocytoma arising from the renal capsule.

Malignant fibrous histiocytoma (MFH) arising from the renal capsule is a rare tumor. We report a case of 55-year-old man with this tumor. Radiological imaging, including magnetic resonance (MR) imaging, was helpful in the differential diagnosis between MFH of the renal capsule and other renal tumors.

Choroid plexus metastasis of colon cancer.

This article presents an extremely rare case of solitary metastasis in the choroid plexus of the inferior horn of the right lateral ventricle three years after a colectomy for colon cancer. We discuss the current literature on this tumor together with the magnetic resonance (MR) imaging and computed tomography (CT) findings.

[Isolated left ventricular noncompaction in the elderly: a case report].

A 83-year-old man with an implanted pacemaker was admitted to our hospital for dyspnea. Echocardiography revealed left ventricular dilation and diffuse hypokinesis mimicking dilated cardiomyopathy. Multiple trabeculations and deep intertrabecular recesses were prominent in the apical and posterior walls.

[Usefulness of dobutamine stress echocardiography in a patient with aortic valve stenosis and left ventricular dysfunction: a case report].

A 76-year-old man with previous antero-septal myocardial infarction and aorto-coronary bypass surgery developed exertional dyspnea. Echocardiography revealed diffuse left ventricular hypokinesis and aortic stenosis with a mean pressure gradient of 29 mmHg. Coronary angiography showed no significant lesions in the bypass grafts and total occlusions of the proximal left anterior descending artery and mid circumflex artery.

[Reversible left ventricular dysfunction manifesting as hyperkinesis of the basal and the apical areas with akinesis of the mid portion: a case report].

Multiple coronary aneurysms resulting from isolated coronary vasculitis in an elderly patient.

An 81-year-old man developed multiple coronary aneurysms, including the left main truncus, that were unexpectedly found by coronary angiography. He had been followed-up for 14 years because of angina pectoris; his initial coronary angiograms in 1985 showed some stenotic segments but no aneurysmal changes. The patient died of gastric cancer in March 2000.

[Fiberoptic intubation via laryngeal mask airway under general anesthesia in the patients with halo vest].

Since 1991, we gave anesthesia to 155 patients with halo vest. All of 128 whose airways could be kept patent by laryngeal mask airway (LMA) were successfully intubated fiberoptically via LMA using the tube exchange catheter under general anesthesia. Four patients developed airway obstruction during the induction of anesthesia, two of whom were awakened and subsequently intubated by awake fiberoptic intubation.

Concomitant Cushing's syndrome due to adrenal adenoma in a patient with systemic lupus erythematosus.

A 51-year-old woman had been administered 5 mg/day of prednisolone due to systemic lupus erythematosus (SLE). She developed hypertension, hypokalemia and a pathologic pubic fracture during two years before admission. Although iatrogenic Cushing's syndrome was initially suspected, we diagnosed her as concomitant Cushing's syndrome due to a left adrenal tumor.

Evaluation of speech function after mesopharyngeal reconstruction with radial forearm flap.

This study examined postoperative speech function in ten patients who underwent mesopharyngeal resection and reconstruction using radial forearm flap. Patient age ranged from 49 to 71 years (mean 60 years) with 9 males and 1 female. Speech function was assessed by articulatory and velopharyngeal function.

Slowly progressive heart failure due to subepicardial myocardial fibrosis in a patient with chronic pericardial effusion.

A 65-year-old woman was admitted to hospital because of orthopnea. She had been followed-up for chronic pericardial effusion detected by echocardiography 10 years previously. Initial echocardiography showed that the left ventricular diastolic diameter (LVDd) was 39 mm and percent fractional shortening (%FS) was 33.

Shape-memory alloy loop snare for endoscopic photodynamic therapy of early gastric cancer.

Background And Study Aims: Photodynamic therapy (PDT) has proved effective in the treatment of gastric cancer, but there is room for improvement. To achieve the technical goal of carrying out endoscopic PDT, endoscopists need to determine the precise area for laser irradiation at adequate dosages. This report describes the use of a shapememory alloy (SMA) loop snare as a useful tool in endoscopic PDT.

Endothelial nitric oxide synthase gene mutation and human leukocyte antigen analyzed in three cases of familial vasospastic angina pectoris.

A 50-year-old woman with rest angina underwent cardiac catheterization; coronary angiography in the presence of acetylcholine revealed 99% coronary spasm of the proximal left anterior descending artery. The patient's 82-year-old mother was also admitted to hospital with rest angina. Her Holter electrocardiogram showed ST-segment elevation during the attack at rest and coronary angiography showed 99% spasm of the right coronary artery and 90% spasm of the left coronary artery.

[Diffuse left ventricular hypokinesis mimicking dilated cardiomyopathy with multi-vessel coronary vasospasm].

We investigated 7 patients with multi-vessel coronary vasospasm (> or = 75%) and diffuse left ventricular hypokinesis by coronary angiography and echocardiography. Four patients were male and 3 were female and mean +/- SD age was 63.0 +/- 11.

Developmental and dynamic canal stenosis as radiologic factors affecting surgical results of anterior cervical fusion for myelopathy.

Study Design: The correlation between preoperative and postoperative lateral functional radiograms and clinical results was analyzed in 74 cases of myelopathy treated by anterior cervical fusion.

Objectives: To clarify the correlation between clinical results and radiologic findings (developmental and dynamic stenosis).

Summary Of Background Data: Although radiologic changes have been reported at the disc level adjacent to anterior cervical fusion, the question of whether these radiologic findings affect the clinical results of anterior fusion has not been resolved.

A case of cervical myelopathy with developmental canal stenosis at the level of the atlas. A case report.

The craniocervical junction is one of the most common sites of malformations. Only three cases of myelopathy due to hypoplasia of atlas have been reported previously. Among these malformations, the hypoplasia of atlas was first described by Wackenheim in 1974.

[Comparative study of sustained-release in theophylline (Slobid, Theolong, Theodur) by pharmacokinetics].

We made a comparative study of three kinds of sustained-release of theophylline compounds by means of analysis of plasma concentrations. The drugs were Slobid (SB) (Up-john) 11 patients (10 men, 1 woman), Theolong (TL) (Eisai) 22 (10 men, 12 women), Theodur (TD) (Nikken chemicals) 34 (18 men, 16 women), who were hospitalized from January 1989 to November 1994. These patients were given oral theophylline, bid at 9:00 and 21:00, plasma concentration of theophylline was determined at 9:00, 12:00, 15:00, 18:00 and 21:00, after plasma concentration reached a plateau.

Atlantoaxial dislocation. A follow-up study of surgical results.

Study Design: The cases of 47 patients with atlantoaxial dislocation exclusive of rheumatoid arthritis, cerebral palsy, and tumors as causative pathologies were reviewed after surgical treatment, which was performed between 1979 and 1993.

Objectives: To investigate the surgical results of atlantoaxial dislocation itself without any systemic factors affected by rheumatoid arthritis, cerebral palsy, and tumors.

Methods: Neck pain (or occipitalgia) and extent of myelopathy at follow-up evaluation were compared with that present before surgery.

Assessment of intravascular ultrasound-bearing balloon catheter-guided percutaneous transluminal coronary angioplasty and stenting.

To investigate the usefulness of an intravascular ultrasound (IVUS)-bearing balloon catheter, we analyzed results in 17 patients with 19 lesions who underwent percutaneous transluminal coronary angioplasty (PTCA) with IVUS-bearing balloon catheters (group A) and 25 patients with 28 lesions who underwent PTCA without IVUS (group B). The patients had angina pectoris with or without old myocardial infarction. The success rate (less than 50% residual stenosis on coronary angiography) in group A was 17/17 patients (100%) and 19/19 lesions (100%), and that in group B was 21/25 patients (84%) and 24/28 lesions (86%) (NS).
