A 73-year-old woman with a history of diarrhea for one year and other various symptoms was admitted to our hospital. Gastrointestinal endoscopy that included enteroscopy with multiple biopsies was performed. However, no significant findings were observed. ⋯ A myocardial biopsy revealed amyloidosis, and a bone marrow biopsy showed multiple myeloma. This case suggests that we should suspect the possibility of amyloidosis in a patient with diarrhea and various symptoms involving multiple organ systems. Additionally, electrocardiograms and echocardiograms should be performed even when gastrointestinal biopsies reveal negative results.

TAFRO syndrome is a systemic inflammatory, lymphoproliferative disorder, but the pathophysiology of the disease is unknown. It is typically characterized by thrombocytopenia, anasarca, a fever, reticulin fibrosis, renal dysfunction, and organomegaly. ⋯ He achieved complete remission with combination therapy of corticosteroids, tocilizumab, and cyclosporin, and remission was maintained even after drug discontinuation at 15 months. Atypical manifestations and complete remission of TAFRO syndrome were remarkable features of our case.

Multicenter Study
A Multicenter Study of Docetaxel at a Dose of 100 mg/m2 in Japanese Patients with Advanced or Recurrent Breast Cancer.
Objective This study examined the pharmacokinetics, safety and anti-tumor activity of docetaxel at a dose of 100 mg/m2 in Japanese patients with advanced or recurrent breast cancer. Methods Japanese patients with advanced or recurrent breast cancer received docetaxel at a dose of 100 mg/m2 intravenously every three weeks. The pharmacokinetics were assessed during the first cycle. ⋯ No complete response and three partial responses were observed in four assessable patients with evaluable lesions. The maximum concentration and area under the blood concentration-time curve were 3,417.5 ng/mL and 4.35 μg・hr/mL (mean), respectively. Conclusion Docetaxel at a dose of 100 mg/m2 was tolerable with acceptable safety profiles and effective for Japanese patients with advanced or recurrent breast cancer with appropriate supportive therapies, and pharmacokinetic (PK) profiles which corresponded approximately with the findings of previous clinical studies.

Objective Patients with hematological malignancies, particularly those with multiple myeloma, often suffer from pathological vertebral compression fractures (VCFs). Consequent and significant spinal pain and paralysis impair the activities of daily living and quality of life and delay subsequent chemotherapy. Balloon kyphoplasty (BKP), which is less invasive than conventional therapies, is a type of percutaneous vertebroplasty in which cement is injected into the broken vertebrae to stabilize the spinal column. ⋯ No severe complications were observed. All patients became able to walk unassisted and underwent early subsequent chemotherapy. Conclusion BKP can be a safe and effective treatment option for pathological VCFs in patients with hematological malignancies and allows for rapid induction with subsequent chemotherapy.

We herein report a case of asymmetrical interstitial lung disease (ILD) that remained almost completely asymmetrical over time on chest computed tomography (CT). An open lung biopsy from the right lung showed severe pleural adhesion, obstruction of the pulmonary artery, and dilated systemic arteries in addition to the usual interstitial pneumonia pattern. Three-dimensional CT angiography showed partial defects of pulmonary arteries on the affected side. After excluding other known causes of ILD and gastroesophageal reflux, we suspected that decreased pulmonary artery perfusion in the present case may have been responsible for the observed asymmetrical unilateral fibrosis.
