The Resection of Thyroid Cancer Was Associated with the Resolution of Hyporesponsiveness to an Erythropoiesis-stimulating Agent in a Hemodialysis Patient with Aceruloplasminemia.

We herein report the case of a hemodialysis patient whose response to an erythropoiesis-stimulating agent (ESA) improved following the resection of thyroid cancer. Her hemoglobin level remained below 7 g/dL, despite the use of ESA. During the search for the causes of her hyporesponsiveness to ESA, papillary thyroid cancer and aceruloplasminemia were found.

Successful closed reduction for iatrogenic displacement of the anatomical neck of the humerus: a case report.

Background: We report a rare case in which closed reduction was successfully obtained for iatrogenically displaced fracture-dislocation of the humeral anatomical neck with a favorable clinical outcome.

Case Presentation: A 53-year old postman suffered from shoulder dislocation with an undisplaced fracture of the humeral anatomical neck which was initially undiagnosed. After the first attempt to reduce the dislocation of the shoulder joint by Stimson's method, complete displacement of the fractured humeral anatomical neck occurred.

Magnetic resonance imaging of articular cartilage abnormalities of the far posterior femoral condyle of the knee.

Background: Incidental articular cartilage lesions of the far posterior femoral condyle (FPFC) are commonly detected. Whether or not these cartilage lesions are symptomatic or clinically significant is unknown.

Purpose: To characterize and assess prevalence of articular cartilage abnormalities of the FPFC and associated bone marrow edema (BME) and/or internal derangements through magnetic resonance (MR) images.

Detection of pain-related molecules in the subchondral bone of osteoarthritic knees.

Knee pain is predominant among osteoarthritis (OA) patients, but the mechanism is poorly understood. We investigated subchondral bone as a source of OA knee pain using immunohistochemistry. Fifteen medial-type OA knees with minimum involvement of the lateral compartment determined by X-ray as well as magnetic resonance imaging that received total knee arthroplasty (TKA) were involved.

RGD peptide-induced cell death of chondrocytes and synovial cells.

Background: Small peptides including the Arg-Gly-Asp (RGD) motif have been used in studies on cell-extracellular matrix (ECM) attachment due to their ability to disturb integrin-mediated attachment on the cell surface. As another biological action of RGD peptides, several reports have shown that RGD peptides are incorporated into cytoplasm and induce apoptosis by direct activation of caspase-3. This study evaluated the effect of RGD peptides on chondrocytes and synovial cells and studied the involvement of caspases.

Ligamentous injuries of the wrist.

The purpose of this review is to summarize ligamentous injury of the wrist. Triangular fibrocartilage complex (TFCC), scapholunate ligament (SLL), and lunotriquetral ligament (LTL) are crucial to wrist stability. Damage to these ligaments causes changes in bone alignment and altered motion pattern.

Spontaneous recurrent hemarthrosis of the knee in the elderly: arthroscopic treatment and etiology.

Purpose: To elucidate the etiology of and find a preferable surgical treatment for spontaneous recurrent hemarthrosis in osteoarthritic knee joints arthroscopically.

Methods: Nineteen patients referred to our institution from affiliate hospitals between April 1998 and October 2006 were involved in this study. Their demographics, preoperative radiographic findings, preoperative magnetic resonance imaging (MRI) findings, arthroscopic findings and procedures performed, the patient's medical history, and the postoperative clinical course were retrospectively reviewed.

Irregularity of medial femoral condyle on MR imaging serves as a possible indicator of objective severity of medial-type osteoarthritic knee-a pilot study.

Irregularly described contour of the femur and the tibia on magnetic resonance (MR) imaging is commonly seen in osteoarthritic (OA) knees. The aim of this study is to examine the relationship between irregularity of contour of medial femoral condyle (tentatively named I-index) and severity of OA. Twenty-six medial-type OA knees with a mean age of 63.

Intracranial subdural hematoma after resection of a thoracic spinal cord tumor.

Intracranial subdural hematoma associated with intracranial hypotension is a rare complication of dural puncture and other procedures on the dura. This report describes the case of a 25-year-old man who developed intracranial subdural hematoma after resection of a thoracic spinal cord tumor. Intracranial subdural hematoma could result in severe and permanent neurologic deficit if it remains unrecognized.
