Multicenter Prospective Study of Color Doppler Ultrasound for Breast Masses: Utility of Our Color Doppler Method.

The use of color Doppler ultrasound (CD) for distinguishing between benign and malignant breast lesions remains controversial. This study (JABTS BC-04 study) was aimed at confirming the usefulness of our CD diagnostic criteria. We evaluated ultrasound images of 1408 solid breast masses from 16 institutions in Japan (malignant: 839, benign: 569).

Clinicopathological features of neuroblastic tumors with opsoclonus-myoclonus-ataxia syndrome: Follicular structure predicts a better neurological outcome.

Neuroblastic tumors (NT) with opsoclonus-myoclonus syndrome (OMS) display characteristic histological features, such as lymphocytic infiltration with lymphoid follicles, indicating an underlying immune response. We retrospectively assessed NT patients from 2001 to 2016. Five cases of NT with OMS and 76 cases of NT without OMS were histopathologically reviewed in this study.

Ultrasound Image Classification of Ductal Carcinoma In Situ (DCIS) of the Breast: Analysis of 705 DCIS Lesions.

The Japan Association of Breast and Thyroid Sonology (JABTS) proposed, in 2003, a conceptual classification system for non-mass abnormalities to be applied in addition to the conventional concept of masses, to facilitate detecting ductal carcinoma in situ (DCIS) lesions. The aim of this study was to confirm the utility of this system and to clarify the distribution of these findings in DCIS lesions. Data on 705 surgically treated DCIS lesions from 16 institutions in Japan were retrospectively reviewed.

[Mediastinal lymph-node carcinoma with no apparent primary lesion; report of a case].

A 57-year-old woman was admitted to our department because of a chest X-ray showing a mass shadow about 40 mm in diameter in the right side of the middle of the mediastinum. A chest computed tomography(CT) scan demonstrated a large tumor, adherent to the superior vena cava and right pulmonary artery. No other metastases and no primary tumor were found.

[A case of racemose hemangioma of the right bronchial artery and intercostal to pulmonary arterial anastomosis].

We reported a case of racemose hemangioma of the bronchial artery and intercostal to pulmonary arterial anastomosis. A 67-year-old woman was admitted because of repeated hemoptysis. Bronchoscopic examination revealed a torous lesion of the right B7 bronchus.

[An operative case of congenital fistula of the right coronary artery to the left ventricle with congestive heart failure].

We reported an extremely rare case of congenital fistula of the right coronary artery to the left ventricle in a 71-year-old man who suffered from difficulty in breathing and palpitation. The diagnosis was confirmed by the right coronary angiography. The fistula was closed by Symbas's operation under cardiopulmonary bypass.

[Successful treatment by using a pedicled omental flap for sternal osteomyelitis and mediastinal infection caused by MRSA].

A 56-year-old male case, who was complicated with sternal osteomyelitis and mediastinitis after aortic valve replacement, was reported. Its infection was caused by MRSA (methicillin resistant Staphylococcus aureus). He was treated with sterilization of wound using povidone iodine, Minomycin solution and its injection for 10 days.
