Neurological and cognitive significance of probiotics: a holy grail deciding individual personality.

The role of the human microbiome in the brain and behavioral development is an area of increasing attention. Recent investigations have found that diverse mechanisms and signals including the immune, endocrine and neural associations are responsible for the communication between gut microbiota and the brain. The studies have suggested that alteration of intestinal microbiota using probiotic formulations may offer a significant role in the maturation and organization of the brain and can shape the brain and behavior as well as mood and cognition in human subjects. The understanding of the possible impact of gut microflora on neurological function is a promising phenomenon that can surely transform the neurosciences and may decipher the novel etiologies for neurodegenerative and psychiatric disorders.

Correlation of metformin with intravenous iodinated contrast media and precautions.

To discuss metformin and iv-contrast induced acute renal failure with its reported cases worldwide, associated risk factors and precautions that can be taken to reduce this tragedy & to address this sensitive issue to my technologist family working in clinical situations. As these studies were observational studies and just report contrast induced nephrotoxicity in different countries by analyzing patients data. By Personal experience or by analyzing data available on PACS (Picture archiving and communication system) most commonly available in Hospitals now a days, that is why these studies did not use any scientific procedure. In our study, we collected opinions of Senior Doctors about use of Metformin before and after contrast study. All Doctors were agreed upon investigation of serum creatinine before contrast study. Doctors were not agreed on single opinion but surely they agreed on stop of Metformin before and after procedure. They said its responsibility of imaging technologist or Radiologist to guide patient about this problem. Diabetic patients using Metformin are at high risk of acute renal acidosis if they are undergoing for iodinated contrast study.
