This study aimed to determine the differences in antibiotic usage patterns in the treatment of acute pyelonephritis according to hospital type and region in Korea. The claims database of the Health Insurance Review and Assessment Service in Korea was used to select patients with the International Classification of Diseases, Tenth Revision code N10 (acute tubulo-interstitial nephritis) or N12 (tubulo-interstitial nephritis, neither acute nor chronic) as the primary discharge diagnosis in 2010-2014. Usage of each class of antibiotics was expressed as the defined daily dose (DDD)/event. ⋯ According to the geographic analyses, third-generation cephalosporins were highly prescribed in some southern regions; fluoroquinolones and aminoglycosides were highly prescribed in some centrally located regions of the Korean peninsula. The hotspots for carbapenem usage included Seoul and Gyeonggi province cluster and Busan cluster: these regions include the capital city and the second biggest city in Korea, respectively. In conclusion, the antibiotic usage patterns for acute pyelonephritis in Korea differ according to the hospital type and region.

Late outcomes of endovascular aortic stent graft therapy in patients with chronic kidney disease.
Endovascular aneurysm repair (EVAR) and thoracic endovascular aortic repair (TEVAR) are effective and minimally invasive treatment options for high-risk surgical candidates. Nevertheless, knowledge about the management of aortic stent graft therapy in chronic kidney disease (CKD) is scarce. This study aimed to examine outcomes after EVAR and TEVAR in patients with CKD. ⋯ The dialysis group had higher risks of all-cause mortality and readmission than the CKD without dialysis and non-CKD groups. Among EVAR/TEVAR recipients, CKD was independently associated with higher in-hospital mortality, postoperative complication, and all-cause mortality rates. Patients with end-stage renal disease on dialysis had worse outcomes than those in the CKD non-dialysis and non-CKD groups.

Arterial resection during pancreatectomy for pancreatic ductal adenocarcinoma with arterial invasion: A single-center experience with 109 patients.
Pancreatectomy for pancreatic cancer with arterial invasion is controversial and performed infrequently. As its indication evolves and neoadjuvant chemotherapy also evolves, it is meaningful to identify short- and long-term outcomes of pancreatectomy with arterial resection (AR). This study aimed to retrospectively analyze the clinical outcomes of pancreatectomy with AR for pancreatic ductal adenocarcinoma. ⋯ Patients with partial response to neoadjuvant chemotherapy showed better OS than those with stable disease (33.7 vs 17.5 months, P = .04). Pancreatectomy with AR for advanced pancreatic cancer showed acceptable procedure-related morbidity and mortality. A survival benefit of neoadjuvant chemotherapy was identified, compared to upfront surgery.

To evaluate the prognostic value of the baseline SUVmax of F-FDG PET-CT in extranodal natural killer/T-cell lymphoma (NKTCL) patients. From January 2010 to December 2015, 141 extranodal NKTCL patients with staging F-FDG PET-CT scan were divided into two group based on SUVmax cutoff value obtained from operating characteristic (ROC) curves. All the patients received radiotherapy, chemotherapy or chemoradiation. ⋯ For extranodal NKTCL patients, a higher baseline SUVmax of F-FDG PET-CT was associated with more aggressive clinical features. An SUVmax ≥ 9.65 was an independent poor prognostic factor for DRFS and PFS. Thus, the baseline SUVmax may be a valuable tool to help identify patients with a high risk of disease progression.

Antimelanoma differentiation-associated gene 5 antibody (anti-MDA5 Ab)-positive clinically amyopathic dermatomyositis (cADM) is frequently complicated with interstitial lung disease (ILD) and has a poor prognosis. Although the short-term prognosis of anti-MDA5 Ab-positive cADM is poor, it has been suggested that the recurrence rate is not higher than that of anti-MDA5 Ab-negative dermatomyositis. Combination therapy with corticosteroids, calcineurin inhibitors, and cyclophosphamide is the gold standard for the remission induction therapy at the onset. Recently, it has been reported that tofacitinib (TOF) could be effective for refractory anti-MDA5 Ab-positive cADM with ILD. Although initial remission induction therapy has been established, therapeutic strategies for relapse cases have not yet been established. ⋯ This case report is the first report suggesting the effectiveness of TOF for recurrent case of anti-MDA5 Ab-positive cADM with ILD. TOF might be an effective therapeutic option for treating recurrent case of anti-MDA5 Ab-positive cADM.
