AIM To examine cytokeratin-18 (CK-18) and caspase-cleaved CK-18 expression in tumours and correlate with clinicopathological outcomes including tumour regression grade (TRG) response. METHODS Formalin-fixed human gastro-oesophageal cancers were constructed into tissue microarrays. The first set consisted of 122 gastric/gastro-oesophageal cancer cases not exposed to neoadjuvant chemotherapy an...

BACKGROUND Adenocarcinoma of the distal esophagus and gastric cardia are defined by the relationship of its epicenter to the gastro-esophageal junction, which is presently defined as the end of the tubular esophagus. We have recently suggested that the true gastro-esophageal junction is best defined by the proximal limit of gastric oxyntic mucosa. AIM To reclassify adenocarcinomas of this reg...

BACKGROUND The possible pathophysiology of the relationship between gastro-esophageal reflux disease and apnea of prematurity has been widely investigated. Various physiological protective reflex responses provide a plausible biological link between gastro-esophageal reflux and apnea of prematurity. It is uncertain whether or not there is a causal relationship between the two diseases. PATIENT'...

Chronic hiccup is a rare but potentially severe condition, that can be symptomatic of a variety of diseases, or idiopathic. Many therapeutic interventions have been reported, most often as case reports. Among other drugs, baclofen has been suggested as a therapy for chronic hiccup. In a large series of patients, we have evaluated its therapeutic position. In patients with chronic hiccup, define...

Objective:The purpose of this study was to investigate the effects of piroxicam co-administration with ethanolic stem-bark extract of Khaya senegalensis on biomarkers of oxidative stress and gastro-toxicity in Wistar rats. Materials and Methods: Thirty healthy male and female Albino Wistar rats (190-220 g) were grouped into six (n = 5) with designated treatments including: Normal saline, piroxi...
