Background:
Duration of digestion/decontamination has a considerable impact on yield of mycobacteria especially from sterile body fluids and pus specimens. Additionally, duration of digestion/decontamination affects the contamination rates. This study evaluates the effect of digestion/decontamination protocol for 15 and 20min versus inoculation of media directly from the sample on contamination rates as well as the yield of mycobacteria from pus and sterile fluids other than cerebrospinal fluids.
Methods:
Pleural fluid (n=60), pus (n=48) and ascitic fluid (n=12) specimens were cultured for mycobacteria and evaluated for contamination and mycobacterial yield using three different processing methodologies ...


Histologic Findings In Biopsies/Resection Specimens From The Small Intestine With Special Emphasis On Celiac Disease: Experience From A Developing Country In South Asia, Huma Arshad, Zubair Ahmad Dec 2012

Histologic Findings In Biopsies/Resection Specimens From The Small Intestine With Special Emphasis On Celiac Disease: Experience From A Developing Country In South Asia, Huma Arshad, Zubair Ahmad

Biopsies from the small intestine especially the duodenum are now being performed much more frequently than in the past. The most frequent reason for performing duodenal biopsies is to evaluate for malabsorption. In the last few years, increased awareness has resulted in more biopsies sent for evaluation of malabsorption, especially celiac disease (CD). In the duodenum, features of malabsorption (increased intraepithelial lymphocytes, villous shortening, and atrophy) were the most common histologic finding seen in 63.4% of cases. Serum tTG levels were available for correlation in 52.8% of cases. In patients with confirmed CD, 53.4% were MARSH IIIb ...
