Effects of Culture Conditions (Microplate and Solvent) on in vitro Antifungal Activity of Caspofungin Against Candida Species.

Effects of the type of microplates and solvent for preparation of caspofungin (CPFG) on antifungal susceptibility testing of CPFG against clinical isolates of Candida albicans, Candida glabrata, and Candida krusei (20 strains each) by broth microdilution method according to the Clinical and Laboratory Standards Institute were evaluated. When CPFG was dissolved in water, MICs against the three Candida species decreased 3.1-6.

A Case of Endoscopic Mucosal Resection of Carcinoma in Adenoma at the Minor Duodenal Papilla.

Here, we describe a case of minor papillary adenocarcinoma in adenoma that was treated with endoscopic mucosal resection (EMR). In a 67-year-old woman, sigmoid colon cancer was incidentally detected on preoperative upper gastrointestinal endoscopy. Endoscopy revealed a slightly elevated lesion at the minor duodenal papilla.

Successful Endoscopic Removal of a Biliary Stent with Stent-Stone Complex after Long-Term Migration.

A 49-year-old man was referred to our hospital for an abnormality of the hepatobiliary enzyme. The patient was diagnosed with primary sclerosing cholangitis 9 years ago, and he had a biliary stent with a string placed as an inside stent. We attempted to remove the stent 6 months later, but the string was cut off, so the stent could not be removed.

[Pharmacological and clinical effects of letermovir (Prevymis), a novel anti-human cytomegalovirus prophylactic drug].

Letermovir is an anti-human cytomegalovirus (HCMV) drug with a novel mechanism of action. Virological characterization and sequence analysis of resistant viruses indicate that the viral DNA terminase complex is the target of this compound. Unlike currently marketed anti-HCMV drugs, which act via inhibition of the viral DNA polymerase, the terminase inhibitor interferes with viral DNA cleavage and packaging of monomeric genome units into capsids.

Conversion surgery for an initially unresectable, locally advanced pancreatic cancer after induction chemotherapy and carbon-ion radiotherapy: a case report.

Background: Pancreatic cancer has a very high mortality rate worldwide, and about 30-40% of all patients have extensive vascular involvement at initial diagnosis that precludes surgical intervention. Here, we describe our experience in a patient with locally advanced pancreatic cancer (LAPC) who underwent R0 conversion surgery after undergoing a combination of chemotherapy and carbon-ion radiotherapy (CIRT), which led to long-term relapse-free survival (23 months).

Case Presentation: A 41-year-old woman presented a month ago with epigastralgia referred to our facility and was subsequently diagnosed with pancreatic cancer cStage III (Ph, TS2 (35 mm), cT4, cCH1, cDU1, cS1, cRP1, cPL1, cVsm0, cAsm1, cN0, cM0) that was also categorized as an unresectable LAPC.

An Intra-Abdominal Desmoid Tumor, Embedded in the Pancreas, Preoperatively Diagnosed as an Extragastric Growing Gastrointestinal Stromal Tumor.

A 45-year-old woman was found to have a pancreatic tumor by abdominal ultrasound performed for a medical check-up. Abdominal contrast-enhanced computed tomography showed a hypovascular tumor measuring 30 mm in diameter in the pancreatic tail. Endoscopic ultrasound-guided fine needle aspiration was performed.

A Serous Cystic Neoplasm of the Pancreas Coexisting with High-Grade Pancreatic Intraepithelial Neoplasia Mimicking an Intraepithelial Papillary Mucinous Neoplasm: A Case Report.

Serous cystic neoplasms of the pancreas are rare exocrine pancreatic neoplasms, most of which are benign and do not communicate with the pancreatic duct. Pancreatic intraepithelial neoplasm (PanIN) is considered a precursor of ductal adenocarcinoma that is microscopically recognized in pancreatic ducts. A 67-year-old Japanese woman presented with a 10-mm multilocular cystic lesion at the pancreatic body.

Laparoscopic splenopancreatectomy for an endocrine tumor with cystic changes: a case report.

The biological behavior of a cystic pancreatic endocrine neoplasm is less aggressive than that of pancreatic neuroendocrine neoplasms, and its prognosis is better. Limited surgery should be considered for cystic pancreatic endocrine neoplasms that are not accompanied preoperatively by lymph node or distant metastasis.

Undifferentiated carcinoma of the ampulla of Vater.

Undifferentiated carcinoma of the ampulla of Vater is a rare disease with unclear and clinical characteristics and prognosis. Here, we report the case of a 61-year-old man with undifferentiated carcinoma of the ampulla of Vater. He presented to our hospital with an increase in hepatobiliary system enzymes that was detected during a health check-up.

Carcinosarcoma of the ampulla of Vater: a case report and literature review.

Background: Carcinosarcoma of the ampulla of Vater is extremely rare, and to the best of our knowledge, this is the third reported study.

Case Presentation: The patient was a 73-year-old man, who presented with a chief complaint of dark urine. After a work-up, we suspected duodenal papillary cancer and performed a subtotal stomach-preserving pancreaticoduodenectomy with lymph node dissection.

Bile duct carcinoma associated with congenital biliary dilatation in a 16-year-old female: a case report and literature review.

We encountered a very rare case of bile duct carcinoma associated with congenital biliary dilatation (CBD) in a 16-year-old female who was admitted to our hospital because of right upper abdominal pain and vomiting. Abdominal computed tomography demonstrated a cystic dilatation of the common bile duct measuring 7 cm in diameter and two enhanced tumors 4 cm in diameter located in the inferior bile duct and middle bile duct. Magnetic resonance cholangiopancreatography clearly demonstrated a cystic dilatation of the extrahepatic bile duct (Todani's CBD classification: type 4-A).

A case study of a collision tumor composed of cancers of the bile duct and pancreas.

In this case report, we describe the extremely rare case of a collision tumor comprising cancers of the bile duct and the pancreas. A 70-year-old man was referred to our hospital with a diagnosis of obstructive jaundice. He was diagnosed with pancreatic head cancer, and we performed a pancreaticoduodenectomy with lymph node dissection.

Discovery of Novel Indazole Derivatives as Highly Potent and Selective Human β3-Adrenergic Receptor Agonists with the Possibility of Having No Cardiovascular Side Effects.

Novel indazole derivatives were prepared and evaluated for their biological activity and cardiovascular safety profile as human β3-adrenergic receptor (AR) agonists. Although the initial hit compound 5 exhibited significant β3-AR agonistic activity (EC50 = 21 nM), it also exhibited agonistic activity at the α1A-AR (EC50 = 219 nM, selectivity: α1A/β3 = 10-fold). The major metabolite of 5, which was an oxidative product at the indazole 3-methyl moiety, gave a clue to a strategy for improvement of the selectivity for β3-AR agonistic activity versus α1A-AR agonistic activity.

Risk factors for migration, fracture, and dislocation of pancreatic stents.

Aim. To analyze the risk factors for pancreatic stent migration, dislocation, and fracture in chronic pancreatitis patients with pancreatic strictures. Materials and Methods.

A case of pancreatic intraepithelial neoplasia that was difficult to diagnose preoperatively.

A 63-year-old female patient presented to a local physician with pain in her back and epigastric region. An abdominal computed tomography (CT) scan revealed a pancreatic tumor, and the patient was referred to our hospital. Multiple imaging studies that included ultrasonography (US), CT, MRI, and endoscopic US revealed a cystic lesion 3-4 cm in size with node-like projections in the body of the pancreas.

Relationship between pain and plasma amino acid levels in chronic pancreatitis.

Objective: Our aim was to investigate the relationship between imbalances of plasma amino acids and pain in chronic pancreatitis (CP).

Methods: Thirty patients with alcoholic CP in an exocrine-insufficient state were examined. We divided them between diet and control group.

Accessory Pancreatic Duct-Portal Vein Fistula: A Rare Complication of Chronic Pancreatitis during Endoscopic Retrograde Cholangiopancreatography.

Pancreatitis, hemorrhage and perforation are the most frequent complications associated with endoscopic retrograde cholangiopancreatography (ERCP). We report a rare case of accessory pancreatic duct-portal vein fistula, which occurred during ERCP in a patient with chronic pancreatitis. To our knowledge, this is the first report of accessory pancreatic duct-portal vein fistula created during ERCP by the use of a guide wire.

Amenorrhea as a rare drug-related adverse event associated with everolimus for pancreatic neuroendocrine tumors.

The patient was an asymptomatic 43-year-old woman. Abdominal ultrasonography and enhanced computed tomography showed a tumor lesion accompanied by multiple cystic changes in the liver and the pancreatic tail. Endoscopic ultrasound-fine needle aspiration was performed on the pancreatic tumor lesion and revealed pancreatic neuroendocrine tumor (PNET).

Smoking and risk for acute pancreatitis: a systematic review and meta-analysis.

We aimed to better understand the relationship between smoking and a risk for acute pancreatitis (AP) in existing observational studies. We identified studies by searching the PubMed, Scopus, and Web of Science databases (from inception through August 31, 2013) and by searching bibliographies of relevant articles. Summary relative risks (RRs) with 95% confidence intervals (CIs) were calculated with fixed-effects and random-effects models.

An intraductal papillary neoplasm of the bile duct at the duodenal papilla.

In recent years, the disease concept of intraductal papillary neoplasm of the bile duct (IPNB) has been attracting attention as a biliary lesion that is morphologically similar to intraductal papillary mucinous neoplasm (IPMN), which is considered to be a counterpart of IPMN. However, there are few reports on IPNB, and a consensus regarding the features of this disease is thus lacking. We experienced an extremely rare case of IPNB occurring in the bile duct at the duodenal papilla, which is a tumor presentation that has not previously been reported.

A case of a giant growing serous cystic neoplasm of the pancreas.

Because of the widespread use of diagnostic imaging in recent years, serous cystic neoplasm (SCN) of the pancreas can often be detected even when small in diameter. SCNs are usually benign, but it is important to differentiate them from other types of cystic tumors. We report a case of a giant growing SCN that posed a challenge in differential diagnosis.

Risk factors for proximal migration of biliary tube stents.

Aim: To analyze the risk factors for biliary stent migration in patients with benign and malignant strictures.

Methods: Endoscopic stent placement was performed in 396 patients with bile duct stenosis, at our institution, between June 2003 and March 2009. The indications for bile duct stent implantation included common bile duct stone in 190 patients, malignant lesions in 112, chronic pancreatitis in 62, autoimmune pancreatitis in 14, trauma in eight, surgical complications in six, and primary sclerosing cholangitis (PSC) in four.
