Heterotopic pregnancy is rare under natural circumstance (conception). We report the first case of heterotopic pregnancy in spontaneous conception with four previous caesarean sections and ruptured tubal ectopic with resultant successful normal intra-uterine pregnancy delivered at term after salpingectomy. A 32-year-old gravida 5 para 4+0 with 3 living children, with 4 previous caesarean sectio...

Gastrointestinal duplication is a congenital rare disease entity. Duplication cyst of the stomach with pseudo stratified columnar ciliated epithelium is extremely rare. The very appearance of a gastric duplication cyst in an adult can present a diagnostic dilemma. In majority of reported cases, the diagnosis is established during surgical exploration. We report on a 34 year-old female patient s...

Pulmonary adenocarcinoma is a common malignancy that often involves calcification; however, bone formation in primary lung adenocarcinoma is extremely rare. In ten cases of primary pulmonary adenocarcinoma with heterotopic ossification, we detected immunoreactivity against TGF-beta1, osteopontin, osteocalcin and Runx2 in the fibroblastic stroma and tumor cells within the area of ossification. O...

The stratified squamous epithelium of the esophagus forms a tight protective barrier. Defects of the barrier function contribute to gastroesophageal reflux disease (GERD), which is manifested as damage to the esophageal epithelium due to exposure to the gastrointestinal refluxate. In this review, we discuss the involvement of NFkB and Nrf2 in esophageal epithelial barrier function. Understandin...

Background and aim: Many neuroendocrine gastrointestinal tumours express receptors for the regulatory peptide somatostatin. Among the five existing somatostatin receptor (sst) subtypes, sst2A is the most frequently expressed in these tumours. However, little information is available about the cellular location of sst2A in corresponding non-neoplastic epithelial tissues. Methods: We searched for...

The gastrointestinal morphology was investigated in three mammalian insectivorous species, namely Acomys spinosissimus, Crocidura cyanea, and Amblysomus hottentotus. The aim of the study was to provide a comprehensive morphological comparison between the different species and to explore whether anatomical gastrointestinal adaptations are associated with the insectivorous diet of these species. ...

Scanning electron microscopy has been used to visualize the residents of microbial communities populating habitats on epithelial surfaces in the gastrointestinal tracts of mice. In the stomach, bacteria form a dense layer on the stratified squamous epithelium of the nonsecreting area. Microbes of at least three morphological types can be seen in this layer, including short rods with round ends,...

Heterotopic pregnancy refers to the presence of simultaneous pregnancies at two different implantation sites. Heterotopic pregnancy is rare, estimated to occur in 1 per 30,000 pregnancies. We report a case of a 27-year-old woman presented to the emergency department with the diagnosis of ruptured ectopic pregnancy. Careful ultrasound assessment indicated the diagnosis of heterotopic pregnancy. ...
