A Japanese man experienced three episodes of hypovolemic shock and was diagnosed with systemic capillary leak syndrome (SCLS). He developed SCLS exacerbation 2 days after receiving a second dose of the Pfizer-BioNTech BNT162b2 mRNA COVID-19 vaccine, 1 year after the third episode. ⋯ A literature review revealed that SCLS attacks often occur 1-2 days after the second COVID-19 vaccination. Patients with a history of SCLS should avoid COVID-19 vaccination and be carefully monitored for 1-2 days if they receive the vaccine.

A 71-year-old man with hyperthyroidism complained of headache lasting two months. He had been using propylthiouracil (PTU) for 14 years. Treatment intensification did not improve the symptoms. ⋯ He received methylprednisolone pulse therapy followed by prednisolone and methotrexate, which improved his headache. PTU-induced AAV-related HP is a rare and indiscernible disease. Therefore, the possibility of the disease should be proactively considered when a PTU user experiences refractory headaches.

A mediastinal thoracic duct cyst that originates from the thoracic duct is a very rare disease in the mediastinum. There have been no reports of mediastinal thoracic duct cyst infection caused by endoscopic treatment. ⋯ We herein report a 75-year-old man with mediastinal thoracic duct cyst infection caused by esophageal endoscopic submucosal dissection. In cases where a mediastinal thoracic duct cyst is found before performing endoscopic esophageal treatment, we should carefully consider the potential risk of post-treatment cyst infection.

A 67-year-old woman with a 2-day history of a fever, headache and disturbed consciousness was admitted to our hospital. Bacillus subtilis was isolated from both the cerebrospinal fluid and blood. ⋯ Next-generation sequencing identified the strain as B. subtilis var. natto, the same strain found in natto, which this patient ate daily. We suspected that some of the B. subtilis that caused the infection may have actually been B. subtilis var. natto.

Objective Anamorelin, a novel selective ghrelin receptor agonist, was approved in Japan for the treatment of cachexia in pancreatic cancer (PC), albeit with limited evidence. This study evaluated the efficacy and safety of anamorelin in PC and examined the impact of the extent of weight loss on the efficacy of anamorelin. Methods We retrospectively investigated consecutive PC patients with cachexia who received anamorelin at our institution between June 2021 and January 2022. ⋯ Conclusion The efficacy of anamorelin was associated with the extent of weight loss. Although anamorelin improved appetite in each weight-loss group, it increased body weight only in the moderate-weight-loss group. Anamorelin was well-tolerated among advanced PC patients, although caution must be practiced when it is used in patients with concomitant diabetes mellitus.
