BACKGROUND This study clarified the long-term results of conservative treatment of rotator cuff tears. MATERIALS AND METHODS This study focused on 103 shoulders diagnosed with rotator cuff tears by magnetic resonance imaging or arthrography at our institution from 1996 to 1999. Sixty-five shoulders were followed up by telephone survey and 43 of these(More)
PURPOSE Rotator cuff tear is the most common shoulder disease in patients with shoulder problems, but its prevalence is not well known. METHODS We performed a health care check-up of locomotive organs in 664 residents (21.3% of the population) in one village. Ultrasonography on bilateral shoulders was performed in all the participants. RESULTS One(More)
Traumatic dislocation most commonly occurs at the shoulder joint. After an initial dislocation of the shoulder, the labrum is usually detached from the glenoid (Bankart lesion). If this lesion fails to heal, surgical repair is necessary. The purpose of this study was to determine the histological and biomechanical healing process of a simulated Bankart(More)
BACKGROUND The present study evaluated the expression of hepcidin mRNA in hepatocellular carcinoma (HCC). METHODS Samples of cancerous and non-cancerous liver tissue were taken from 40 patients with HCC who underwent hepatectomy. Expression of hepcidin mRNA was evaluated by real-time PCR, and compared in tumors differing in their degree of(More)
Nodular fasciitis is a benign reactive lesion, often mistaken for a soft tissue sarcoma in clinical practice. Involvement of the finger is very rare and, as a result, in this location the lesion has sometimes been treated by ray amputation because of misdiagnosis. We report on the clinical and histological features of nodular fasciitis in a 30-year-old man(More)
Low-intensity pulsed ultrasound is a pain-free therapy performed daily at home by the patient and has been shown to promote fracture healing. Teriparatide is a parathyroid hormone preparation that activates osteoblastic bone formation and is also reported to be effective in promoting bony union. We report the case of a 56-year-old Japanese male with a(More)
For resection of advanced hepatocellular carcinoma (HCC) in which tumor thrombus (TT) extends into inferior vena cava (IVC) or right atrium (RA) surgery is challenging and requires skillful techniques. Here, we report a case of recurrent HCC with TT extending to the RA, who underwent successful resection with tumor thrombectomy without concomitant(More)
A 67-year-old male, who had a left hepatectomy for hepatocellular carcinoma, was readmitted to our hospital because of a left hemiparesis. A brain computed tomography scan and an r-carotid angiogram revealed a large mass involving the right parietal area, and thus a brain tumor removal was performed. A histological diagnosis of the removed brain tumor found(More)
Nontraumatic anterior subluxation and dislocation of the hip joint are extremely rare. A 58-year-old woman presented to our outpatient clinic with left hip pain with a duration of 15 years. There was no history of trauma or other diseases. Her hip pain usually occurred only on walking and not at rest. Physical examinations demonstrated no tenderness in the(More)
BACKGROUND/AIMS We investigated, for the first time, the protective effect of erythropoietin (EPO) against liver ischemia-reperfusion (I-R) injury in a pig model. METHODOLOGY Partial hepatic ischemia was maintained for 60 min in a pig. Pigs were allocated to 4 groups (n=5 each): (1) Control group with I-R injury (Vehicle); (2) EPO group with I-R injury,(More)
