Autoimmune pancreatitis (AIP) is a benign disorder and a unique form of chronic pancreatitis with several characteristic features. A cystic formation that mimics a pseudocyst is a rare finding. There have been a few reports of AIP complicated by pancreatic cysts. We present a case of AIP with multiple pseudocysts and obstructive jaundice caused by(More)
The prognosis of advanced hepatocellular carcinoma (HCC) tends to be poor. Spontaneous regression of this lesion is extremely rare. In this report, we describe a case of HCC which spontaneously regressed along with a metastatic lesion of the chest wall. A huge HCC in the right lobe, the largest diameter of which was about 15 x 12 cm, developed in a(More)
Primary pancreatic lymphoma is rare, comprising 0.2-4.9% of all pancreatic malignancies and less than 1% of cases of non-Hodgkin's lymphoma. Many patients are diagnosed with lymphoma after radical resection. We report a rare presentation of diffuse large B cell lymphoma, appearing as a primary tumor of the pancreas. A 61-year old female was admitted to the(More)
SUMMARY Based on the work by Helleseth [1], for an odd prime p and an even integer n = 2m, the cross-correlation values between two decimated m-sequences by the decimation factors 2 and 4p n/2 − 2 are derived. Their cross-correlation function is at most 4-valued, that is, −1±p n/2 2 , −1+3p n/2 2 , −1+5p n/2 2. From this result, for p m 2 mod 3, a new(More)
Patient-derived tumor xenograft is the transfer of primary human tumors directly into an immunodeficient mouse. Patient-derived tumor xenograft plays an important role in the development and evaluation of new chemotherapeutic agents. We succeeded in generating a patient-derived tumor xenograft of a biliary tumor obtained by endoscopic ultrasound-guided(More)
SUMMARY In this paper, for an odd prime p and i = 0, 1, we investigate the cross-correlation between two decimated sequences, s(2t + i) and s(dt), where s(t) is a p-ary m-sequence of period p n − 1. Here we consider two cases of d, d = (p m +1) 2 2 with n = 2m, p m ≡ 1 (mod 4) and d = (p m +1) 2 p e +1 with n = 2m and odd m/e. The value distribution of the(More)
BACKGROUND AND STUDY AIMS The optimal core biopsy needle for endoscopic ultrasound (EUS) is unknown. The principle aim of this study is to compare outcomes of EUS-fine-needle biopsy (EUS-FNB) with a new 19-gauge EUS histology needle (ProCore, Cook Medical Inc., Winston-Salem, North Carolina, United States) to a conventional 19-gauge Tru-Cut biopsy (EUS-TCB)(More)
BACKGROUND/AIMS Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and Trucut biopsy (TCB) are sensitive techniques for diagnosing mediastinal lesions, but it is unclear how either one or both should be used to obtain a pathologic diagnosis. The objective of our study was to evaluate whether EUS-TCB impacts the diagnosis of mediastinal lesions(More)
