Guillain-Barré syndrome (GBS) has occasionally occurred in people who have received coronavirus disease 2019 (COVID-19) vaccines. Dysgeusia is rare symptom of GBS. ⋯ Although autoantibodies against glycolipids were not detected, immunotherapy with intravenous immunoglobulin and methylprednisolone pulse therapy effectively ameliorated the symptoms. Our report suggests that the COVID-19 vaccine may induce various clinical subtypes of GBS, including a rare variant with sensory ataxia and dysgeusia.

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.

We herein report a 71-year-old woman presented with a fever, arthralgia, general malaise and leg muscle stiffness following administration of the COVID-19 mRNA vaccine (Comirnaty, Pfizer-BioNTech). Laboratory findings showed an elevated C-reactive protein level and erythrocyte sedimentation rate. In addition, Gallium-67 scintigraphy demonstrated an increased uptake in multiple joints. ⋯ These findings met the diagnostic criteria for polymyalgia rheumatica (PMR), and when we started steroid treatment, her symptoms improved rapidly. This patient developed PMR after receiving a COVID-19 mRNA vaccine (Comirnaty, Pfizer-BioNTech). This case is considered to be valuable, as the HLA-DRB1 allele was also confirmed.
