Iron deposition in autopsied liver specimens from older patients receiving intravenous iron infusion.

Background: Vitamins and minerals are routinely administered by total parenteral nutrition (TPN). However, in Japan, adjustments in iron dosage are difficult because blended mineral preparations are often used. It is therefore unclear whether the iron content is appropriate in cases of long-term TPN.

[The consciousness survey and the effect of educational intervention of Advance Care Planning (ACP) including post-mortem to elderly residents living in old New Town of big city].

Aim: Awareness reform aims to enable survival in an aging society, and ultimately, improve healthcare. An ideal way to achieve this is by implementing Advance directive (Ad) and Advance Care Planning (ACP), which do not usually include postmortem events. This study aims to create opportunities for Ad and ACP to include the postmortem period as a trigger for this awareness reform.

Enhanced vaccination effect against influenza by prebiotics in elderly patients receiving enteral nutrition.

Aim: We investigated the effect of prebiotics on the immunological response after influenza vaccination in enterally fed elderly individuals. The intervention group was given an enteral formula containing lactic acid bacteria-fermented milk products. In addition, two different types of other prebiotics, galacto-oligosaccharide and bifidogenic growth stimulator, were also given.

Lansoprazole induces collagenous colitis in the colon of Mongolian gerbils.

Collagenous colitis (CC) is an illness characterized by chronic diarrhea with possible effects on neoplastic development, but there have been no reports in animals. We therefore tried to establish CC development in a Mongolian gerbil (MG) model by long-term continuous lansoprazole (LPZ) administration and aimed to clarify the relationship between LPZ administration and CC occurrence. We divided 69 gerbils into 6 groups: Helicobacter pylori (Hp)-infected+high-dose LPZ, Hp-infected+low-dose-LPZ, Hp-infected, high-dose-LPZ, low- dose-LPZ, and control.

Comparative evaluation of the Japanese diagnostic criteria for autoimmune pancreatitis.

Objectives: The aim of the study was to clarify the problems of the Japanese criteria for autoimmune pancreatitis (AIP) in comparison with the other criteria.

Methods: We retrospectively investigated the clinical, imaging, serological, and histopathogic features, together with other organ involvement and response to steroid, in 50 patients with AIP diagnosed on the basis of the Japanese, Korean, HISORt, and Asian criteria. Thirty-five patients with pancreatic cancer were enrolled as a control group.

Small bile duct involvement in IgG4-related sclerosing cholangitis: liver biopsy and cholangiography correlation.

Background: IgG4-related sclerosing cholangitis (IgG4-SC) needs to be differentiated from primary sclerosing cholangitis (PSC). In this study, we performed a retrospective study to reveal cases in which liver needle biopsy was useful for differential diagnosis.

Methods: Nineteen patients with IgG4-SC and 22 patients with PSC were studied.

Successful treatment for pouchitis with rebamipide refractory to a combination of metronidazole (MNZ) and ciprofloxacin (CFX).

A 35-year-old male who had undergone proctocolectomy and ileo-anal pouch surgery (IPAA) because of ulcerative colitis presented with worsening diarrhea and hematochezia. Pouchitis was diagnosed, and he was prescribed with metronidazole (MNZ) and a betamethasone enema. However, his condition did not remarkably improve despite these strategies.

Gastroesophageal and laryngopharyngeal reflux symptoms correlate with histopathologic inflammation of the upper and lower esophagus.

Background: The presence of laryngopharyngeal reflux disease is controversial when abnormal sensation of the laryngopharynx is felt without heartburn.

Goals: The aims of this study were to investigate the relationship between abnormal sensation of the laryngopharynx and gastroesophageal reflux, and to elucidate the pathology of laryngopharyngeal reflux disease by investigating histopathologic findings of the upper and lower esophagus.

Study: Upper and lower esophageal tissues were biopsied by endoscopy in 300 consenting patients, excluding those with serious diseases.

Impact of real-world stress on cardiorespiratory resting function during sleep in daily life.

To examine if real-world stress affects the restorative function of sleep in daily life, we studied the impact of college examinations on cardiorespiratory resting function during sleep. In healthy college students, at 1 week before, the day before, and the first day of semester-end examinations pulse wave signal during sleep at their own residences was measured continuously with a wristband-shaped wireless transdermal photoelectric sensor. The cardiorespiratory resting function was assessed quantitatively as the power of a high-frequency component of pulse rate variability, a surrogate measure of respiratory sinus arrhythmia.

Prognostic indicators estimated by (99m)Tc-GSA in acute liver damage.

A prognostic estimation formula of acute liver damage was evaluated by using clinical data and technetium-99m-diethylenetriaminepentaacetic acid-galactosyl-human serum albumin ((99m)Tc-GSA) scintigraphy in order to determine operability for orthotopic liver transplantation (OLT). Forty-six patients hospitalized for acute liver damage were divided into survival (n=35) and non-survival (n=11) groups. Univariate and multivariate analyses were used to identify significant factors that affected prognosis.

Clinicopathological study of hepatic nodular lesions in patients with alcoholic liver cirrhosis.

Background: There have been few reports concerning the occurrence of hepatocellular carcinoma (HCC) in heavy drinkers not sensitized by hepatitis B virus (HBV) or hepatitis C virus. With current advances in diagnostic methods, hypervascular tumors are often discovered on imaging findings in alcoholics, and it is important to differentiate them from HCCs.

Methods: The subjects were 16 alcoholics who had hepatic nodules and were hepatitis B surface antigen negative and hepatitis C virus antibody negative and were classified into two groups: (1) the HBV group with hepatitis B surface antibody and/or hepatitis B core antibody and (2) the alcoholic group without these antibodies.
