OBJECTIVE: To investigate cognitive and mental workload assessments, which may play a critical role in defining successful mentorship.

MATERIALS AND METHODS: The 'Mind Maps' project aimed at evaluating cognitive function with regard to surgeon's expertise and trainee's skills. The study included electroencephalogram (EEG) recordings of a mentor observing trainee surgeons in 20 procedures involving extended lymph node dissection (eLND) or urethrovesical anastomosis (UVA), with simultaneous assessment of trainees using the National Aeronautics and Space Administration Task Load index (NASA-TLX) questionnaire. We also compared the brain activity of the mentor during this study with his own brain activity while actually performing the same surgical steps from previous procedures populated in the 'Mind Maps' project.

RESULTS: During eLND and UVA, when the mentor thought the trainee's mental demand and effort were low based on his NASA-TLX questionnaire (not satisfied with his performance), his EEG-based mental workload increased (reflecting more concern and attention). The mentor was mentally engaged and concerned while he was engrossed in observing the surgery. This was further supported by the finding that there was no significant difference in the mental demands and workload between observing and operating for the expert surgeon.

CONCLUSIONS: This study objectively evaluated the cognitive engagement of a surgical mentor teaching technical skills during surgery. The study provides a deeper understanding of how surgical teaching actually works and opens new horizons for assessment and teaching of surgery. Further research is needed to study the feasibility of this novel concept in assessment and guidance of surgical performance.

Key words: Antibiotic associated diarrhea-Clostridium Difficile-
Polymerase chain reaction-Chromogenic culture media.
Background: Antibiotic associated diarrhea (AAD) can be a significant
problem resulting in incomplete duration of therapy and development of
microbial resistance and can cause severe complications e.g. electrolyte
imbalances, dehydration, pseudomembranous colitis, toxic megacolon or
even death.
Clostridium Difficile is the leading cause of antibiotic associated diarrhea
in hospitalized patients.
Materials and Methods: In this work we aimed to evaluate
Chromogenic agar versus polymerase chain reaction in diagnosis of
Clostridium Difficile infection.
The study included 100 cases of antibiotic associated diarrhea and 20
completely healthy individuals as control group
Results: The results was that by PCR for cases, 2/100 cases were positive
for toxin B,and one/100 case positive for Binary toxin, no cases were
positive for toxin A, 2/100 cases were positive for tpi gene, for control
group no samples were positive for any toxin or tpi gene.
