Vaccine-induced hypermetabolic lymph nodes have been clinically observed following coronavirus disease 2019 (COVID-19) mRNA vaccination. Specifically, the booster dose of the mRNA vaccines, produced by Pfizer and Moderna, has been linked to a relatively high incidence of lymphadenopathy. We present the case of a kidney transplant recipient who developed an enlarged abdominal mass after receiving a booster dose of the COVID-19 mRNA vaccine. This mass occupied the retroperitoneal space, infiltrated the psoas muscle, and resulted in ureteric compression and hydronephrosis. Percutaneous drainage and analysis of the perirenal fluid revealed the presence of lymphatic fluid. In summary, lymphadenopathy is a recognized adverse reaction to the Pfizer and Moderna vaccines. Patients with compromised immune systems should be informed about the incidence and potential severity of lymphadenopathy following booster vaccination.

Epinephrine is frequently used to control local bleeding during surgery. However, it may be associated with complications, such as pulmonary edema, reversible cardiomyopathy, and cardiac arrest. We encountered a case of stress induced cardiomyopathy (SIC) after local epinephrine instillation. The SIC is manifested with typical left ventricular apical ballooning and clinical symptoms of a myocardial infarction without coronary stenosis. Although its prognosis is more favorable than a myocardial infarction, anesthesiologists need to be aware of the possible adverse effects of local epinephrine infiltration.

Transplant renal artery stenosis (TRAS) is a common surgical complication after kidney transplantation (KTP) and is the cause of allograft dysfunction. TRAS is a potentially curable cause of refractory hypertension and allograft dysfunction which accounts for approximately 1% to 5% of cases of post-transplant hypertension. Acute cellular rejection (ACR) is also common after KTP, which is the main cause of allograft dysfunction. Although the incidence of ACR has declined with the advent of new immunosuppressive drugs, it is still around 15% worldwide. Although each disease is frequently seen individually, seeing both together is rare. A 42-year-old man with end stage renal disease underwent KTP, and the donor was his younger brother. Four months after KTP, his serum creatinine was increased to 2.1 mg/dL, and renal biopsy showed interstitial lymphocytic infiltration and tubulitis. With the diagnosis of acute T-cell mediated rejection, steroid pulsing therapy was started, but it was resisted. Therefore thymoglobulin 60 mg (1 mg/kg/day) was administered for 6 days, but serum creatinine was 1.8 mg/dL. Abdomen magnetic resonance angiography showed TRAS, stenosis at the anastomosis site and lobar artery in the lower pole. Percutaneous transluminal angiography was performed successfully. After balloon angioplasty, the stenotic lesion showed a normal size and blood flow. The patient's renal function returned to normal levels and he is currently being followed up for 9 months.

Hyperuricemic patients with gouty arthritis or tophi, a serum uric acid concentration of 8.0 mg/dL or higher, and complications should be treated with urate-lowering drugs. Conventionally, allopurinol is used to treat hyperuricemia and gout, but it is necessary to adjust the dosage according to the degree of renal impairment. Uncommonly, allopurinol may have severe or fatal side effects. The non-purine xanthine oxidase inhibitor febuxostat undergoes hepatic metabolism and may require less dose adjustment in association with renal function. It is considered to be an alternative treatment for hyperuricemic patients with chronic kidney disease. Our experience suggests that low-dose febuxostat is a promising alternative to allopurinol for the treatment of gouty arthritis or tophi in peritoneal dialysis patients.

BACKGROUND: We performed a prospective, double blind study to compare the clinical effect of vertical infraclavicular brachial plexus block produced by 0.5% levobupivacaine and 0.5% ropivacaine for upper limb surgery. METHODS: We included 60 patients receiving upper limb surgery under infraclavicular brachial plexus block. The infraclavicular brachial plexus block was performed via the vertical technique with 30 ml of 0.5% levobupivacaine or 0.5% ropivacaine. We observed which nerve type was stimulated and scored the sensory and motor block. The quality of block was assessed intraoperatively. The duration of sensory and motor block and complications were assessed. RESULTS: There were no significant differences in frequencies of stimulated nerve type, evolution of sensory and motor block quality, or success of block. There were no significant difference in duration of sensory block, but duration of motor block was prolonged after 0.5% levobupivacaine. There were no complications. CONCLUSIONS: Both 0.5% levobupivacaine and 0.5% ropivacaine had similar effects in the vertical infraclavicular brachial plexus block.

OBJECTIVES: Alpha1-antitrypsin (AAT) is the main inhibitor of human neutrophil elastase, and plays a role in counteracting the tissue damage caused by elastase in local inflammatory conditions. The study evaluated the involvement of AAT in nasal allergic inflammation. METHODS: Forty subjects with mono-sensitization to Dermatophagoides pteronyssinus (Dpt) were enrolled. Twenty allergic rhinitis patients frequently complained of nasal symptoms such as rhinorrhea, stuffiness, sneezing, and showed positive responses to the nasal provocation test (NPT) with Dpt (Group I). The other 20 asymptomatic patients showed sensitization to Dpt but negative NPT (Group II). The levels of AAT, eosinophil cationic protein (ECP), and Dpt-specific IgA antibodies were measured in the nasal lavage fluids (NLFs), collected at baseline, 10 minutes, 30 minutes, 3 hours, and 6 hours after the NPT. Nasal mucosa AAT expression was evaluated with immunohistochemical staining from Group I and Group II. RESULTS: At baseline, only the Dpt-specific IgA level was significantly increased in the NLFs of Group I compared with Group II, while ECP and AAT levels were not significantly different between two groups. After Dpt provocation, AAT, ECP, and Dpt-specific IgA levels were significantly increased in the NLFs of Group I during the early and late responses. The protein expression level of AAT was mostly found in the infiltrating inflammatory cells of the nasal mucosa, which was significantly increased in Group I compared to Group II. CONCLUSION: The increment of AAT showed a close relationship with the activation of eosinophils induced by allergen-specific IgA in the NLFs of patients with allergic rhinitis after allergen stimulation. These findings implicate AAT in allergen-induced nasal inflammation.
