Insulin degludec (IDeg), a new long-acting basal insulin, and FlexTouch, a new injection device, recently became available in Japan. The efficacy and usefulness of IDeg and FlexTouch, compared with insulin glargine or detemir, were assessed in patients with type 2 diabetes mellitus. ⋯ Replacing basal insulin with IDeg is useful for the stable and accurate control of blood glucose levels in type 2 diabetes for those receiving a higher dose of basal insulin. Furthermore, the patients with a shorter duration of diabetes and a single insulin injection preferred FlexTouch.

Analyses of tumor biopsy samples from non-small cell lung cancer patients with acquired epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) resistance are expected to reveal the molecular mechanisms of resistance. However, due to limited tissue availability, performing such analyses can be challenging. We herein investigated the feasibility of tumor rebiopsy in this patient population. ⋯ In this study, few patients had a site of progression capable of being accessed using relatively noninvasive biopsy procedures. Further investigations are warranted to develop more optimal treatment strategies after PD in patients with oligoprogressive disease or CNS failure.

We herein report the case of a 42-year-old man with a one-year history of ulcerative colitis who presented with exacerbated bloody diarrhea, a productive cough and increasing breathing difficulties. Colonoscopy revealed typical deep ulcers in the rectosigmoid colon and atypical multiple sucker-like ulcers in the transverse colon, and computed tomography of the chest demonstrated wall thickening of the trachea and bronchi. ⋯ Based on these findings, the patient's respiratory symptoms were strongly suspected to be due to ulcerative colitis-related tracheobronchitis. Treatment with systemic corticosteroids subsequently resulted in a rapid clinical improvement.

Myelodysplastic syndromes (MDS) are a group of hematological neoplasms associated with ineffective hematopoiesis and that transform to acute leukemia. Distinguishing MDS from other cytopenias is sometimes difficult even for trained hematologists. WT1, the gene mutated in Wilms' tumor, was found expressed in acute myeloid leukemia and MDS. The amount of WT1 in peripheral blood and bone marrow (BM) is low in low-risk MDS subtypes, and is high in high-risk MDS subtypes. However, the role of WT1 in the differential diagnosis between MDS and other diseases showing cytopenia has not been fully addressed. The present study evaluated whether WT1 expression level can assist in the differential diagnosis of MDS from other cytopenias. ⋯ WT1 might be a good marker to differentiate low blast percentage MDS and cytopenia VR.

Case Reports
A Patient with the GLA p.E66Q Mutation Exhibiting Vascular Parkinsonism and Bilateral Pulvinar Lesions.
A 76-year-old man was admitted to our hospital due to gait difficulty. Brain imaging indicated bilateral pulvinar lesions and moderate white matter lesions. The serum α-galactosidase A levels were measured for the differential diagnosis of bilateral pulvinar lesions and were found to be abnormally low. ⋯ A GLA mutation analysis showed the p. E66Q mutation, which is speculated to be a functional polymorphism rather than a disease-causing mutation of Fabry disease. Enzyme replacement therapy did not result in a marked improvement, however, the disease progression stopped.
