TAFRO syndrome (thrombocytopenia, anasarca, myelofibrosis, renal dysfunction, and organomegaly) is an atypical manifestation of multicentric Castleman's disease. Although overproduction of interleukin-6, vascular endothelial growth factor, and other cytokines may partially explain the pathophysiology of this rare syndrome, the precise mechanisms underlying the renal dysfunction associated with the condition remain unclear. Here, we describe a case of a 69-year-old male with TAFRO syndrome. He was treated with immunosuppressive agents and his renal function improved...

Helicobacter pylori infection results in chronic gastritis, peptic ulcer, or gastric cancer; therefore, eradication of this bacterium is essential. The strategy for developing effective vaccines against H. pylori entails immunization of mice with a combination of classical and recombinant H. pylori antigens, but this has proven to be onerous in all cases. Areas covered: We have reviewed literature databases in PubMed and Scopus using the key words H. pylori, vaccine, and vaccination and have conducted a systematic review of published clinical trials and animal model studies on vaccines against H...

Helicobacter pylori has coexisted with humans for approximately 60,000 years and greater than 50% of the global population is infected with H. pylori. H. pylori was successfully cultured in vitro in 1983 and studies of H. pylori have achieved substantial advances over the last 35 years. Since then, H. pylori has been characterized as the primary pathogenic factor for chronic gastritis, peptic ulcer, and gastric malignancy. Numerous patients have received H. pylori eradication treatment, but only 1-2% of H. pylori-infected individuals ultimately develop gastric cancer...

A 61-year-old man was referred to the urology department in our hospital with gross hematuria and hydro nephrosis. Cystoscopy revealed a smooth mass lesion in his bladder, and a transurethral biopsy was performed. Signet ring cell carcinoma was found in the submucosa. Upper gastrointestinal endoscopy revealed an ulcerated lesion in his gastric body. Biopsy specimens obtained from the ulcerated lesion showed signet ring cell carcinoma. No other primary lesions were detected using colonoscopy, gallium scintigraphy, or computed tomography of the chest...

Postlaparotomy management for elderly patients with underlying comorbidities is always a challenge because of poor cardiorespiratory reserves and prolonged effect of anesthetic drugs. For these reasons, such patients usually require intensive care unit (ICU) admission in the postoperative period. We report a case of an 85-year-old chronic smoker with controlled diabetes mellitus who needed an emergency laparotomy for a perforated gastric ulcer. Unfortunately, there was a shortage of ICU backup. With the successful conduct of an early surgery using combined general and regional anesthesia, the use of sugammadex (Bridion, Merck Sharp & Dohme Corp, Oss, the Netherlands) as a reversal agent, a skilled surgeon, and good postanesthesia care, the patient did not require ICU admission...

We investigated the gastroprotective effect of apricot kernel oil on ethanol induced gastric ulcer in rats. Male Wistar albino rats were divided into control, ethanol and apricot kernel oil + ethanol groups. The fatty acid composition of apricot kernel oil was determined using GC-MS. A gastric ulcer index was defined as the area percentage of the gastric mucosa consisting of ulcerated tissue. Gastric tissue was investigated by TUNEL staining for apoptosis, immunohistochemical iNOS staining, measurement of gastric IL-10 and IL-6 expression by ELISA and assays of catalase, malondialdehyde and superoxide dismutase...

Helicobacter pylori (H. pylori) infection leads to gastric inflammation, peptic ulcer and gastric carcinoma. H. pylori activates NADPH oxidase and increases reactive oxygen species (ROS), which induce NF-κB activation and IL-8 expression in gastric epithelial cells. Dysfunctional mitochondria trigger inflammatory cytokine production. Peroxisome proliferator-activated receptors-γ (PPAR-γ) regulate inflammatory response. Astaxanthin is a powerful antioxidant that protects cells against oxidative stress. The present study was aimed at determining whether astaxanthin inhibits H...

Background and study aims: Gastric cancer is known to reside in some gastric ulcers but what predicts this association is still unclear. Historically it has been thought that the increasing size of gastric ulcers may be a predictor for harbouring malignancy. Giant gastric ulcers are arbitrarily defined as ≥3 cm. The aim of this retrospective study was to examine patients with giant gastric ulcers within a single tertiary centre over a 10-year period. Our primary outcomes included the malignancy yield in giant gastric ulcers and to determine if any demographic, clinical or endoscopic predictors for malignancy exist...

The modern therapy for peptic ulcer disease and other acid peptic diseases is based on administration of proton pump inhibitors (PPI) which have fully replaced anacids, parasympatholytics and histamine H2 receptor antagonists. The most effective way is to administer proton pump inhibitors in the morning on an empty stomach in a single daily dose. It is a very safe therapy, despite the fact that a potential adverse effect of long-term PPI treatment on the efficacy of other medications (clopidogrel), on bone metabolism and development of respiratory infections have been discussed recently...

The colon has large capacities for K+ absorption and K+ secretion, but its role in maintaining K+ homeostasis is often overlooked. For many years, passive diffusion and/or solvent drag were thought to be the primary mechanisms for K+ absorption in human and animal colon. However, it is now clear that apical H+ ,K+ -ATPase, in coordination with basolateral K+ -Cl- cotransport and/or K+ and Cl- channels operating in parallel, mediate electroneutral K+ absorption in animal colon. We now know that K+ absorption in rat colon reflects ouabain-sensitive and ouabain-insensitive apical H+ ,K+ -ATPase activities...

A well-known example of gastrointestinal cancers metastasizing to the skin is Sister Mary Joseph's nodule, which usually presents as a cutaneous nodule on the umbilicus. In this case, a 91-year-old man was referred to our dermatology clinic for a rapidly growing 3 cm × 2 cm ulcerative nodule at his chin. Biopsy showed skin metastasis originating from a gastric adenocarcinoma. The subcutaneous and cutaneous manifestation of gastric cancer is very rare and associated with a poor prognosis and widespread metastatic disease as presented in this case...
