BACKGROUND: Gastric cancer is a heterogeneous malignant disease associated with environmental and genetic predisposing factors. While gastric cancer incidence and mortality fell greatly globally over the past decades, it remains the fourth cause of cancer-related death worldwide. Thus, prevention of gastric cancer is still a major strategy for improvement of gastric cancer prognosis. SUMMARY: Helicobacter pylori infection has been demonstrated to be a major risk factor for the development of gastric cancer...

Background: Ureteral stenosis is part of the common complications of renal graft reported in 3% to 7% of cases. Multiple treatments have been introduced regarding length and position of the stenosis. Metal stents for urologic purpose were created in 1998. Double percutaneous antegrade and transurethral retrograde access to a ureteral stenosis to a long-term metal stent procedure has been rarely described. Case Presentation: Here, we present a case of a ureteral stricture in a double ipsilateral kidney graft with a common ureter...

Guttural pouch mycosis (GPM) is a rare but potentially life-threatening condition in horses. GPM is caused by a fungal invasion into the mucosal lining of the guttural pouches and, frequently, the associated neurovascular structures. Although several species of fungi have been associated with this disease, Aspergillus spp. appear to be the most common isolated from the guttural pouches. However, it remains unclear which are the predisposing factors leading to the development of the infection. The objectives of the present study were to experimentally reproduce an infection by Aspergillus fumigatus and to follow the natural evolution of the mycosis...

We report a case of Henoch-Schonlein purpura (HSP) presenting without typical skin lesion; atypical symptoms initially appeared following influenza infection. A 4-year-old girl with influenza presented with epigastric pain and vomiting. On physical examination, there was epigastric tenderness, but no other signs, such as skin rash. On the second day, she vomited blood 10 times. Ultrasonography indicated focal bowel wall thickening in the right upper quadrant. Esophagogastroduodenoscopy showed oedematous and purpuric mucosa in the gastric pylorus and duodenum...

BACKGROUND: Endoscopes represent the medical devices most commonly linked to health care-associated outbreaks and pseudo-outbreaks. Most of the recent outbreaks and pseudo-outbreaks have resulted from contaminated automated endoscope reprocessors (AER) or the use of damaged or malfunctioning bronchoscopes or contaminated equipment. OBJECTIVES: We investigated a pseudo-outbreak of Pseudomonas putida and Stenotrophomonas maltophilia recovered from bronchial washing (BW) specimens obtained during bronchoscopy in a bronchoscopy unit...

BACKGROUND: Helicobacter pylori infection is a major cause of gastric diseases. The clinical implications of H. pylori infection in various diseases outside the gastrointestinal system have also been reported, including in some respiratory disorders. In this study, we investigated the seroprevalence of H. pylori in patients with mild to moderate COPD in an Asian country with a high prevalence of H. pylori infection. Also, we aimed to elucidate the association between the seroprevalence of H...

BACKGROUND: There is a high prevalence of gastro-duodenal disease in sub-Saharan Africa. Peptic ulcer disease in dyspeptic patients, 24.5%, was comparable to prevalence of gastro-duodenal disease among symptomatic individuals in developed countries (12 - 25%). Limited data exists regarding its associated risk factors despite accumulating evidence indicating that gastroduodenal disease is common in Ghana. OBJECTIVES: This study investigates risk factors associated with gastro-duodenal disease at the Korle-Bu Teaching Hospital, Accra, Ghana...

BACKGROUND: Risk factors for gastric cancer during continuous infection with Helicobacter pylori have been well documented; however, little has been reported on the risk factors for primary gastric cancer after H. pylori eradication. We conducted a retrospective, endoscopy-based, long-term, large-cohort study to clarify the risk factors for gastric cancer following H. pylori eradication. METHODS: Patients who achieved successful H. pylori eradication and periodically underwent esophagogastroduodenoscopy surveillance thereafter at Toyoshima Endoscopy Clinic were enrolled...

Branchiogenic carcinoma (BC) usually appears as a mass lesion with a predominant cystic component. Since lymph node metastasis from oropharyngeal carcinoma (OPC) has a cystic appearance, it is occasionally difficult to distinguish between BC and nodal metastases from clinically silent OPC. Factors associated with the malignant transformation process in BC remain obscure. The present study reports the case of a 56-year-old man with a right cystic cervical mass that was diagnosed as squamous cell carcinoma based on examination by fine-needle aspiration biopsy...

INTRODUCTION: Paraplegic patients are at greater risk of developing complications following ureteroscopic lithotripsy because of urine infection associated with neuropathic bladder, difficulties in access due to altered anatomy of urinary bladder and urethra, spinal curvature, spasticity, and contractures. We report the occurrence of large subcapsular hematoma following ureteroscopy and discuss lessons we learn from this case. CASE REPORT: A 48-year-old male patient with spina bifida underwent ureteroscopy with laser lithotripsy and ureteric stenting for left ureteric stone and staghorn calculus with hydronephrosis; laser lithotripsy was repeated after 3 months; both procedures were performed by a senior urologist and did not result in any complications...

Numerous outbreaks of duodenoscope-associated transmission of multi-drug resistant bacteria have recently been reported. Unlike prior episodes of endoscope-transmitted infections, the latest outbreaks have occurred despite strict adherence to duodenoscope reprocessing guidelines. The current standard for all flexible endoscope reprocessing includes pre-cleaning, leak testing, an additional manual cleaning step, and high-level disinfection. When these steps are strictly followed, the risk of infection transmission during endoscopy is exceedingly rare...

BACKGROUND: Helicobacter pylori is an important risk factor for gastritis, peptic ulcers and gastric cancer. The prevalence in developed countries is lower than 40 % but higher than 80 % in some developing countries. It is 75 % in Ghana. The Helicobacter urease test (HUT) is performed at endoscopy and gives an accurate diagnosis. The HUT is not routinely done at our facility and presumption of H. pylori is made based on endoscopic findings and H. pylori eradication prescribed, as the incidence in the general population is presumed high...

BACKGROUND AND STUDY AIMS: We previously reported that narrow-band imaging with magnifying endoscopy (NBI-ME) revealed a unique "gastritis-like" appearance in approximately 40 % of early gastric cancers after Helicobacter pylori eradication. Because rates of gastric cancer are increasing in patients with non-persistent infection of H. pylori, we aimed to clarify contribution factors to obscure tumors after therapeutic or spontaneous eradication. PATIENTS AND METHODS: NBI-ME findings were examined retrospectively in 194 differentiated-type adenocarcinomas from H...

Primary gastric tumors are very rare in children. Burkitt lymphoma is a common type of non-Hodgkin's lymphoma, and gastric Burkitt lymphoma usually occurs in the aged. When involving the gastrointestinal tract, primary gastric Burkitt lymphoma is very rare in younger childhood. Many gastric lymphomas including mucosa-associated lymphoid tissue lymphoma are associated with Helicobacter pylori infection or acute bleeding symptom. We report a seven-year-old boy who presented with only some vomiting and postprandial pain...
