Background/Aims: Patients with IgA nephropathy (IgA-N) are thought to have immune system disorders that frequently result in high serum IgA levels and a relatively high susceptibility to upper respiratory infections. Aims: To clarify the influence of the specific immune response of IgA-N patients on the clinicopathological features of the disease, we measured the whole-blood-producing capacity of interferon-α (IFNα-PC). We then compared these findings with clinical and histopathological parameters, including tissue macrophage infiltration, during both histologically active and latent phases. Patients and Methods: Fifty-one inpatients with IgA-N and 70 healthy controls were examined. According to the histological findings, 32 patients had disease in the active phase (AP), and 19 were in the latent phase (LP). Results: In AP patients, IFNα-PC showed positive correlations to serum creatinine, blood urea nitrogen, serum β2-microglobulin (s-β2MG), urinary total protein (U-TP), and urinar...

A 70-year-old man with a medical history of diabetes mellitus presented to a local clinic with seven days history of right flank pain and fever. Because there was no symptomatic improvement after one-week antibiotic administration, abdominal ultrasonography and computed tomographic scans were performed to show mass lesions in the right hydropelvis, and he was transferred to our hospital. Retrograde pyelography revealed a retrocaval ureter and a ureteral stent was indwelt. After the symptoms improved, the lesions were removed by percutaneous nephrostomy and fungal balls were diagnosed as Candida parapsilosis after culture. After intermittent one-week irrigation of the renal pelvis with normal saline, the nephrostomy tube was removed. In six-month follow-up, mild hydronephrosis remains without fungal ball recurrence. To the best our knowledge, there has been no case report of Candida parapsilosis fungal balls in the urinary tract.

The diagnosis of pancreatic ductal adenocarcinoma (PDAC) by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) can be challenging to distinguish tumor cells from benign epithelium (BE). The aim of the present study was to set a minimal antibody panel to differentiate PDAC from contaminated BE in EUS-FNA specimens. Immunohistochemistry using claudin 4, EZH2, Ki-67, maspin, p53, and S100P was performed on tissue microarray sections containing 53 PDACs and 33 BE as well as cell blocks of EUS-FNA including 53 PDACs and 22 BE. The positive rate was scored as 0 to 4+. The receiver operating characteristic curve was applied to determine a cutoff point, and the Classification And Regression Trees method was used to obtain a classification tree of the best panel. The cutoff point was 1+ for claudin 4, EZH2, Ki-67, p53, and S100P and 2+ for maspin. All BE scored 0 for p53. The classification tree revealed using p53, S100P, and claudin 4 was the most powerful. The sensitivity and sp...
