ABSTRACT
Introduction The mucosa in the cardiac region of the stomach has been less understood. Cardiac mucosa (CM) with less parietal and oxyntic cells has been defined as a normal mucosa. Studies have shown that CM can be the result of occult reflux. Oxyntic mucosa (OM) is normal, and it changes to CM with age. In advancing age, it is more common to find CM instead of OM and oxyntocardiac mucosa (OCM). This study is an attempt to examine the distribution of the three different types of mucosa in various age groups. Materials and methods The study was conducted in the Department of Anatomy and Department of Forensic Medicine and Toxicology of Gauhati Medical College, Guwahati, Assam, India, from 2017 to 2019. Once the stomach was opened, histological specimens were prepared, and the type of mucosa was observed and recorded. Then, the distribution of the types of mucosa in various age groups was analyzed. Results The distribution of mucosa varies significantly across different age groups, and CM increases with age. Conclusion Our present study suggests that CM frequency increases with age. This is in accordance with studies that suggest that CM is a result of occult reflux with age. This observation creates a scope to revise the approaches for upper gastrointestinal (GI) endoscopy.
ABSTRACT
INTRODUCTION: Traumatic brain injury (TBI) or head injury is one of the leading causes of morbidity and mortality globally. TBI includes a fractured skull as an indicator of insult which can affect the treatment outcome as well. The development of any fracture depends on a combination of factors defining the intrinsic properties of the bone and the extrinsic factors related to the impact. A decrease in bone mass secondary to deficiency of calcium (Ca) and phosphorus (P) can be a significant factor intrinsic to the skull bone, which can modulate the outcome of the impact by increasing the susceptibility of bones towards fractures. We undertook this research to find out whether or not the Ca and P concentration in skull bone has a role to play as an intrinsic factor, in the development of skull fracture following Road Traffic Accidents (RTAs). METHODOLOGY: In this case-control study conducted for two years, we collected 94 bone samples, i.e. 47 each, from skull bones with head injuries following RTA, with (case) and without (control) fracture of the skull. The elemental analyses for the bony concentration of Ca and P in both the groups were then compared using energy dispersive X-ray (EDX). Unpaired t-test and Fisher's exact test was used for statistical analysis. RESULTS: The elemental analysis of bones provided evidence that suggests that whilst; Ca is the only mineral that appears to have a significant correlation with the development of fracture skull, the overall Ca: P ratio of less than 1.99 increases the chances of skull fracture by 3.9 times. CONCLUSIONS: Both individual bony Ca concentration and Ca: P ratio can be regarded as important intrinsic factors for the development of skull fracture.
