Introduction: Microorganisms can colonize the surfaces of cadavers and may pose health hazards to the students and the staff handling them. The objective of the study was to study the spectrum of bacteria and fungi colonizing the surfaces of cadavers and to determine the need to follow infection control protocols during their handling. Materials and methods: A total of 100 swabs were collected from superficial and deep surfaces of the cadavers and its surroundings. The swabs were cultured on blood agar and Mac Conkey’s agar plates for isolation of bacterial species and Sabourauds Dextrose Agar (SDA) slants for isolation of fungal species. Identification of the bacterial and fungal isolates was done using standard bacteriological and mycological methods respectively. Results: Overall culture positivity rate was 78%. There was predominance of isolation of bacterial species (50%). Escherichia coli and Coagulase negative Staphylococci [CoNS] (23.07 % each) were the predominant bacteria isolated and Aspergillus species (37.50%) was the predominant fungus isolated from human cadavers. Conclusions: Various bacteria and fungi colonized the surface of cadavers. Therefore, the study emphasizes the need for practicing “Standard infection control protocols” in the dissection hall while handling the cadavers.

To evaluate the comparison of analgesic efficacy of preoperative intravenous (IV) ketorolac versus tramadol in preventing postoperative pain after mandibular third molar surgery. Methodology: Hundred patients in the age group of 20-40 years with asymptomatic impacted mandibular molars were randomly allocated into one of the two groups. All the patients underwent third molar surgery under local anesthesia. Group I received IV ketorolac 30 mg and Group II received IV tramadol 50 mg preoperatively. The difference in postoperative pain was assessed by five primary parameters: pain intensity being measured hourly by Wong-Baker pain assessment scale for 6 h, onset of analgesia, duration of action, total number of analgesics consumed, and patient's global assessment. Results: Throughout the 6 h investigation period, patients reported significantly lower pain intensity scores, longer duration of action, lesser postoperative analgesic consumption, and better global assessment in ketorolac when compared to tramadol group. Patients in the ketorolac group significantly performed better than the tramadol group in terms of all parameters except onset of analgesia. Conclusion:The result of the present study shows that preoperative IV ketorolac 30mg is more effective than tramadol 50mg for postoperative pain following third molar surgery.
