Fetal "cardiac mucosa" is not adult cardiac mucosa

Origin of cardiac mucosa: ontogenic consideration.

The origin and histology of the cardiac mucosa remains controversial. The classical concept that the cardiac mucosa is of gastric origin has been challenged by those who advocate that the cardiac mucosa results from a metaplastic esophageal process. Some regard cardiac mucosa as consisting solely of pure mucous glands, whereas others accept the presence of isolated parietal cells within the muc...

Cardiac mucosa in the remnant esophagus after esophagectomy is an acquired epithelium with Barrett's-like features.

BACKGROUND The cervical esophagus is normally lined by squamous epithelium and is usually not exposed to gastroesophageal reflux. The aims of this study were, first, to investigate whether cardiac mucosa can be acquired in the remnant cervical esophagus after esophagectomy and cervical esophagogastrostomy and, second, to characterize this mucosa if present. METHODS The medical records of 100 ...

Expression of cytochrome p450 and other biotransformation genes in fetal and adult human nasal mucosa.

Despite recent progress in the identification and characterization of numerous nasal biotransformation enzymes in laboratory animals, the expression of biotransformation genes in human nasal mucosa remains difficult to study. Given the potential role of nasal biotransformation enzymes in the metabolism of airborne chemicals, including fragrance compounds and therapeutic agents, as well as the p...

autoimmune enteropathy: not all flat mucosa mean coeliac disease

a 62-year-old woman complaining of severe malabsorption was diagnosed with celiac disease based on the findings of flat, small intestinal mucosa and hla-dq2 positivity, although celiac serology was negative. this diagnosis was questioned due to the lack of clinical and histological improvement after a long period of strict gluten-free diet. the detection of enterocyte autoantibodies guided to t...
