A 57-year-old Japanese man was admitted to the hospital with back pain and fever, multiple lung nodules, and abdominal aortic aneurysm (AAA). Laboratory tests performed at admission showed an increased proteinase 3 anti-neutrophil cytoplasmic antibody (PR3-ANCA) level. Video-associated thoracoscopic lung biopsy was performed; pathologic examination showed granulation tissue with necrosis and multinucleated giant cells. The diagnosis of granulomatosis with polyangiitis (GPA) was confirmed on the basis of the clinical presentation, laboratory findings, and lung biopsy. All symptoms were ameliorated, and the serum level of PR3-ANCA declined following treatment with prednisolone and cyclophosphamide. Although the association of GPA with AAA is rare, GPA may be included among the large vessel vasculitides that can give rise to aortic aneurysm.

Purpose This trial was conducted to compare effects of continuing versus withholding single-pill combination tablets consisting of angiotensin receptor blockers (ARBs) and calcium channel blockers (CCBs) on perioperative hemodynamics and clinical outcomes. Methods Patients undergoing minor abdominal or urological surgery (n = 106) were randomly assigned to Group C, in which ARB/CCB combination tablets were continued until surgery, or Group W, in which they were withheld within 24 h of surgery. Perioperative hemodynamics and clinical outcomes were compared between the Groups. Results The incidence of hypotension during anesthesia requiring repeated treatment with vasoconstrictors was higher in Group C than Group W (p = 0.0052). Blood pressure during anesthesia was generally lower in Group C than Group W (p < 0.05) despite significantly more doses of ephedrine and phenylephrine administrated in Group C (p = 0.0246 and p = 0.0327, respectively). The incidence of postoperative hypertension did not differ between Groups (p = 0.3793). Estimated glomerular filtration rate (eGFR) on the preoperative day did not differ between Groups (p = 0.7045), while eGFR was slightly lower in Group C than Group W on the first and third postoperative days (p = 0.0400 and p = 0.0088, respectively), although clinically relevant acute kidney injury did not develop. Conclusions Continuing ARB/CCB combination tablets preoperatively in patients undergoing minor surgery increased the incidence of hypotension during anesthesia, increased requirements of vasoconstrictors to treat hypotension, and might deteriorate postoperative renal function, albeit slightly. These results suggest that withholding ARB/CCB tablets preoperatively is preferable to continuing them. Clinical trial registration This trial is registered with the Japan Registry of Clinical Trials (jRCT) at Japanese Ministry of Health, Labour, and Welfare (Trial ID: jRCT1031190027).

Anesthesia for patient with large anterior mediastinal mass might induce life‐threatening complication. Maintaining the spontaneous breathing throughout the procedure and finding rescue position are the cornerstones of anesthetic management.

May-Hegglin anomaly (MHA) is an inherited autosomal dominant disorder characterized by giant platelets and inclusion bodies in granulocytes, and thrombocytopenia. There is no consensus on the perioperative management of this disorder. We report a case involving a patient with MHA who was perioperatively managed without platelet transfusion for cervical laminectomy and laminoplasty. In our case, the platelet count was measured to be 0.6 × 10/µL using an automatic blood cell counter. Peripheral blood smear and genetic test analyses were performed, leading to a definitive diagnosis of MHA. However, clot retraction, serotonin release, and platelet aggregation were normal. Total intravenous anesthesia with propofol and remifentanil, in combination with intermittent injection of fentanyl, was administered. The total blood loss volume was 300 mL, and perioperative course was uneventful. Visual platelet count and platelet function were preserved in this case, although platelet or red blood cell transfusion was not performed. No bleeding tendency was observed during perioperative management.

Hypervirulent Klebsiella pneumoniae (hvKP) is recognized as a lifethreatening community‐acquired infection associated with pyogenic liver abscess. However, rhabdomyolysis secondary to hvKP infection is rare. To the best of our knowledge, we report the first case of rhabdomyolysis due to hvKP infection in a patient who survived septic shock syndrome.

A 65-year-old man with Parkinson’s disease (PD) underwent spine surgery under general anesthesia, 13 hours after the last medication for PD. Postoperatively, negative pressure pulmonary edema developed following upper airway obstruction, a possible complication of PD. Oxygenation improved with high-flow nasal cannula therapy. Continued medication might have prevented such complications.
