A 77-year-old man presented with right inguinal lymphadenopathy and swollen parotid and submandibular glands bilaterally. Histopathology revealed germinal center B-cell type diffuse large B-cell lymphoma (DLBCL) in the inguinal lymph node. ⋯ Systemic chemotherapy for DLBCL led to shrinkage of the lymph nodes and disappearance of the submandibular gland swelling, as confirmed by fluorodeoxyglucose-positron emission tomography/computed tomography. Although concomitant IgG4-RD and lymphoma have been reported, their simultaneous diagnosis is rare; therefore, a biopsy of all involved organs is crucial in cases with unusual organ involvement.

A 56-year-old man presented to our hospital with dyspnea on exertion for two months. Bilateral pleural effusions were found, and a close examination revealed a chylothorax, including adenocarcinoma. ⋯ Chemotherapy was administered for CUP, and thoracentesis, pleurodesis, ascites puncture, and nutritional therapy were performed for chylothorax and chylous ascites. Although drainage frequency and tumor marker levels (CA19-9, DUPAN-2, and Span-1) temporarily decreased, disease control deteriorated, and the patient died 12 months after the initial diagnosis.

Aims The main purpose of this study was to evaluate the associations between circulating angiopoietin-like protein 6 (ANGPTL6) levels and various diabetes- and atherosclerosis-related variables in patients with type 2 diabetes. Methods Serum ANGPTL6 levels in patients with type 2 diabetes hospitalized for glycemic control and/or diabetic education were measured using a chemiluminescent immunoassay (CLIA). Results Most patients had elevated HbA1c levels; 85.7% and 71.4% of patients had HbA1c levels of (8% and (9%, respectively. ⋯ In the multiple regression analysis, ANGPTL6 had a significant positive association with triglyceride (TG) in one of the models in which it was included as a variable. Furthermore, ANGPTL6 also showed significant positive associations with CRP and IMT in models in which they were included as variables. Conclusion The current study suggests that circulating levels of ANGPTL6 may be negatively associated with poor glycemic control and positively associated with the degree of atherosclerosis, as reflected by IMT, in patients with type 2 diabetes, most of whom had elevated HbA1c levels.

Diagnostic Pitfalls of the Bleeding Origin after a Percutaneous Renal Biopsy: A Report of Two Cases.
A percutaneous renal biopsy (PRB) is a standard procedure for diagnosing renal disease, but can cause bleeding complications. Bleeding after a PRB can be classified as early- or late-onset, depending on the timing of the onset of the bleeding symptoms (<24 h or ≥24 h). ⋯ In both cases, the origin of the bleeding vessel was misjudged during the first examination. We discuss the diagnostic pitfalls of the origin of bleeding after a PRB and propose measures to avoid falling such pitfalls.

A 25-year-old Japanese man developed visual disturbance with eye pain and was diagnosed with optic neuritis associated with anti-myelin oligodendrocyte glycoprotein antibodies. His symptoms improved temporarily after steroid therapy but chronically relapsed many times after tapering the steroid dose. ⋯ Maintenance intravenous immunoglobulin (IVIg) therapy successfully decreased the annual recurrence rate from 1.15 to 0.27 times/year and the maintenance dose of oral prednisolone from 35 to 5 mg/day. Maintenance IVIg therapy is a promising option for preventing disease relapse in such cases.
