TAFRO syndrome, a rare systemic inflammatory disorder, commonly develops in an acute or subacute manner, with an aggressive clinical behavior. A substantial number of cases of TAFRO syndrome presenting with abdominal pain, and adrenal abnormalities on imaging have also been reported. A 54-year-old man developed severe acute abdominal pain. ⋯ Although the abdominal pain resolved spontaneously, a fever and anasarca were observed. The patient was eventually diagnosed with TAFRO syndrome, and corticosteroid administration resulted in remission. TAFRO syndrome should be included in the differential diagnosis of acute abdomen and adrenal abnormalities.

The coexistence of leucine-rich glioma-inactivated 1 (LGI1) and contactin-associated protein-like 2 (CASPR2) autoantibodies in the same individual is surprisingly often observed. We herein report the first case of LGI1 encephalitis followed by Isaacs syndrome in which LGI1 and CASPR2 antibodies in the serum and cerebrospinal fluid (CSF) were measured during the entire disease course. After the resolution of limbic encephalitis, LGI1 antibodies disappeared from the CSF simultaneously with the appearance of CASPR2 antibodies in the serum. The alternating presence of these pathogenic autoantibodies along with the clinical and phenotypic alternations suggested that LGI1 encephalitis was associated with CASPR2 autoantibody production in the peripheral tissue, leading to CASPR2-associated Isaacs syndrome.

Objective Hereditary ATTR (ATTRv) amyloidosis was once an incurable disease; however, in recent years, disease-modifying therapies, such as tafamidis and patisiran, have become available. We herein report the medical care situation in an ATTRv amyloidosis non-endemic area of Japan. Methods We confirmed the information in the medical records of our department and analyzed the data retrospectively. ⋯ Although it took a long time to start treatment among our experienced cases, there were some cases in which treatment could be introduced relatively early. Conclusion ATTRv amyloidosis is treatable and should be included in the differential diagnosis of neuropathy so that it can be diagnosed early and introduced into treatment. In the near future, the presymptomatic diagnosis of ATTRv amyloidosis and genetic counseling will become more important.

Case Reports
A Hepatitis B Virus Reactivation Case Potentially Triggered by the Onset of Diffuse Large B Cell Lymphoma.
An 81-year-old man underwent rituximab-containing chemotherapy for chronic lymphocytic leukemia (CLL). Thirteen years after his last chemotherapy, he was diagnosed with hepatitis B virus (HBV) reactivation. He was then treated with entecavir, and improvement was seen in his liver injury. ⋯ Despite chemotherapy, he contracted the coronavirus disease 2019 (COVID-19) and died of COVID-19. We suspect that HBV reactivation was triggered by DLBCL. When HBV reactivation occurs a long time after chemotherapy has concluded, the onset of DLBCL should be considered.

Observational Study
The Prognostic Utility of a Geriatric Assessment for Patients with Pancreatic Cancer Receiving Gemcitabine-based Chemotherapy: A Prospective Observational Study.
Objective To evaluate the effect of a pretreatment geriatric assessment on the clinical outcomes in older patients with unresectable or recurrent pancreatic ductal adenocarcinoma (PDAC) scheduled to receive gemcitabine (GEM)/GEM+nab-paclitaxel (GnP). Patients Older patients with unresectable PDAC scheduled to receive GEM/GnP who visited Kyorin University Hospital and cooperating institutions were enrolled and followed from April 2015 to March 2020. The maximum observation period was two years. ⋯ Conclusion The baseline PS, ADL, and IADL may be prognostic factors in older PDAC patients. In addition, a normal frontal lobe function and depression scores prior to treatment initiation that rapidly worsened during treatment were independently associated with a reduced OS. Selecting appropriate interventions and improving the therapeutic environment may prolong the OS in such patients.
