[Ascending aortic aneurysm associated with von recklinghausen disease].

We report a case of ascending aortic aneurysm complicated with von Recklinghausen disease. A 57-year-old man was referred to our institution for further evaluation of the atrial fibrillation. Computed tomography (CT) revealed an aneurysm of the ascending aorta.

[Role of PET/CT in tuberculosis--can we distinguish tuberculoma from lung cancer by PET/CT examination].

Differentiating lung cancers from tuberculoma is very important, because in Japan, lung granulomas arise mostly from tuberculosis. However, diagnosis of tuberculoma is very difficult, because of its nonspecific radiographic appearances and the difficulty of bacteriological confirmation of the disease. 18F-FDG PET have contributed significantly to the diagnosis of lung cancer, but FDG is not a cancer-specific agent, so tuberculoma also have been reported to accumulate.

Postoperative prophylactic effect of fondaparinux for prevention of deep venous thrombosis after cemented total hip replacement: a comparative study.

The aim of this study was to estimate the effective administration procedure of fondaparinux for prevention of venous thromboembolism after cemented total hip replacement (THR) in Japanese patients. The study included 471 Japanese patients. The dose regimens were 2.

Antibiotics-impregnated cement spacers in the first step of two-stage revision for infected totally replaced hip joints: report of ten trial cases.

Background: Periprosthetic infection is one of the serious complications after total hip arthroplasty (THA). This study analyzed the perioperative and postoperative status of patients who underwent antibiotics-impregnated cement spacer technique in the first step of the two-stage revision.

Methods: Ten joints of the nine patients (mean age, 65 years; seven women, two men) received two-stage revision as a result of infection that appeared after primary THAs in seven joints, aseptic revision in one, and recurrent type in two.

[A case of recurrence after curative total gastrectomy for gastric cancer successfully treated by combination chemotherapy with CPT-11 and CDDP].

A male in his sixties underwent total gastrectomy for gastric cancer in August, 2002. After surgery, he underwent 4 courses of adjuvant chemotherapy with S-1. About 2 years after the surgery, PET-CT detected liver metastasis and lymph node metastasis, so treatment with CPT-11+CDDP was started with the following regimen: 60 mg/m2 CPT-11 and 30 mg/m2 CDDP biweekly.

Distribution of myeloid dendritic cells and plasmacytoid dendritic cells in the synovial tissues of rheumatoid arthritis.

Objective: To examine the precise tissue distribution of dendritic cells (DC) and indoleamine 2,3-dioxygenase (IDO)-expressing cells in synovial tissue and synovial fluid (SF) from patients with rheumatoid arthritis (RA) and osteoarthritis (OA).

Methods: Synovial tissues from 30 patients with RA and 7 with OA were immunohistochemically stained for DC markers. The examined areas were classified into 5 categories based on pathobiological staging and histopathological grading systems.

[Emergent endovascular stent-graft treatment for traumatic injury of descending aorta; report of a case].

A 71-year-old man was transfered to our hospital with acute aortic rupture due to a hit in the back by a log. Chest computed tomography (CT) demonstrated dissecting aneurysm of thoracic descending aorta, mediastinal hematoma, rib fracture and pulmonary contusion, We performed emergent endovascular stent-graft placement with local anesthesia successfully. The post operative course was uneventful.

[Reactivation of Epstein-Barr virus is involved in the pathogenesis of lymphomatoid granulomatosis].

Recent studies point to a role of Epstein-Barr virus in the pathogenesis of lymphomatoid granulomatosis. Little is however known about the association of the pathogenesis of the disease with Epstein-Barr virus reactivation. A 46-year-old man presented with fever and general malaise.

[A case of mesalazine-induced pleuritis with hemophagocytic findings].

A 25-year-old woman who had been receiving mesalazine for 2 weeks for ulcerative colitis presented with a nonproductive cough, high fever, and exertional dyspnea. Her chest radiograph showed bilateral pleural effusion. At first, infectious pleuritis was suspected and antibiotics were administered, but the pleural effusion increased and high fever continued.

[A case of gastric cancer initially presented by bilateral chylothorax].

The patient, a 66-year-old woman, visited our hospital with chief complaints of nocturnal coughing and dyspnea. Chest radiography revealed bilateral pleural effusion, and she was admitted to our hospital to undergo more thorough examination. The bilateral pleural effusion was identified as chyle.

A patient with adult Still's disease with an increased Chlamydia pneumoniae antibody titer.

Adult Still's disease is an important differential diagnosis of pyretic disease and it does not necessarily appear to be a distinct disease entity. The etiology of adult Still's disease is not yet known. However, it has been considered that adult Still's disease may be triggered by certain infections, such as the Coxsackie, parvo B19, rubella, mumps, Epstein-Barr, and cytomegalo virus, as well as mycoplasma, toxoplasma, and so on.

CO2 laser-assisted microvascular anastomosis: biomechanical studies and clinical applications.

Experiments have been performed using CO2 laser-assisted microvascular anastomoses, and they demonstrated the following features, in comparison with conventional anastomoses: ease in technique; less time consumption; less tissue inflammation; early wound healing; equivalency of patency rate and inner pressure tolerance; but only about 50 percent of the tensile strength of manual-suture anastomosis. Six clinical applications in 16 vessels are reported, using this procedure. The preliminary results of these cases would appear to be the first successful replantations and free tissue transfers using CO2 laser-assisted microvascular anastomoses in man.
