We herein report a 73-year-old woman with BRAF V600E-mutated colon cancer treated with encorafenib plus cetuximab with binimetinib as standard salvage therapy for patients with advanced colorectal cancer. She developed bilateral serous retinal detachment the next day, and the regimen was discontinued, resulting in complete resolution by the third day. ⋯ Thus, binimetinib was presumed to have been the cause of the retinal detachment. This clinical course suggests the need for close monitoring of patients for vision impairment and close collaboration with ophthalmologists.

Objective The prognosis differs considerably between patients with psychogenic hyperventilation syndrome (HVS) and those with urinary tract infection (UTI)-associated sepsis; however, the nonspecific symptoms and signs make the diagnosis and management difficult. We herein report the utility of a blood gas analysis for distinguishing HVS from UTI with suspected sepsis. Methods This single-center retrospective cohort study was conducted in a tertiary-care hospital in Japan. ⋯ Patients with HVS had alkalemia and lower PCO2 levels than patients with UTI with suspected sepsis, but the serum lactate levels were similar between the groups. The ROC analysis determined the pH cut-off value to be 7.509 (sensitivity: 0.91; specificity: 0.86) and the PCO2 cut-off value to be 21.6 mmHg (sensitivity: 1.00; specificity: 0.64). Conclusion Elevated serum lactate levels alone cannot be used to differentiate between patients with HVS and those with UTI with suspected sepsis, but the degree of pH and PCO2 abnormality can help with the differential diagnosis.

Behçet's disease (BD) is a multisystem inflammatory disease of unknown origin. It rarely but occasionally occurs together with myelodysplastic syndrome and primary myelofibrosis. ⋯ Considering the lack of a response to treatment and other features, we suspected complication with intestinal Behçet's-like disease. Our case suggests relationships among BD, trisomy 8, and PV.

Objective Graft failure (GF) is a life-threatening complication of hematopoietic stem cell transplantation (HSCT). A standardized conditioning regimen and an appropriate graft source of salvage HSCT for GF have not yet been established. Some case series have shown good hematopoietic recoveries after salvage HSCT using a short-term reduced-intensity preparative regimen consisting of fludarabine (30-90 mg/m2), cyclophosphamide (2 g/m2), and total-body irradiation (2 Gy). ⋯ The 1-year overall survival (OS) rate after the salvage HSCT was 50.0%, and the median OS was 281 (range, 23-1,638) days. Cumulative incidences of non-relapse mortality and relapse at 1 year were 50.0% and 10.0%, respectively. Conclusion CBT using this short-term reduced-intensity conditioning regimen may be a promising salvage therapy for GF.

Case Reports
"An Unbalanced Diet Limited to the Consumption of Boiled Vegetables Led to the Onset of Scurvy."
Scurvy is a rare disease caused by a vitamin C deficiency. Vitamin C is a water-soluble vitamin found in vegetables and fruits, but it is lost after boiling. A 59-year-old man presented with gingival pain after having a tooth extracted five years previously. ⋯ His serum vitamin C level was below the detectable limit. His symptoms immediately improved with vitamin C administration. This case emphasized that consuming only boiled vegetables can lead to the onset of scurvy.
