Veal is a rich nutrient medium that provides a suitable environment for proliferation of veal spoiling microorganisms and common food-borne pathogens. In this study, the effects of irradiation on the veal microbiological quality and half life of minced beef during chilled storage was investigated. ⋯ These results indicated that irradiation could be employed as an effective mean to inactivate common food-borne pathogens namely S. aureus and increases the half life of veal.

Axonal polyneuropathy (APN) is a common kind of neurologic disorders, which is normally diagnosed by electrodiagnostic methods. Different muscles were studied to find a muscle, which can be considered as a reliable site for early diagnosis of mild APN; this muscle should be easily activated by patient, has the highest sensitivity to EMG changes of APN, and has the lowest rate of false positive results in normal subjects. ⋯ The higher frequency of polyphasic MUAP, the higher frequency of FP, and finally, the ability of all patients in activation of PT voluntarily, all support the usefulness of PT for EMG studies in APN patients.

Haloperidol has an established role in nausea and vomiting prophylaxis and possible effects on multiple aspects of postoperative recovery including pain and sedation. The purpose of this study was to evaluate the effects of low-dose intraoperative intravenous haloperidol on quality of recovery (QoR) and pain control after general anesthesia and surgery. ⋯ Intraoperative small-dose IV haloperidol is effective against post-operative nausea and vomiting with no significant effect on overall QoR. It may also attenuate the analgesic effects of morphine PCA.

Ondansetron has analgesic properties. The aim of the present study was to assess the analgesic effect of 8 mg ondansetron when added to lidocaine for intravenous regional anesthesia (IVRA). ⋯ The addition of 8 mg ondansetron to lidocaine for IVRA reduced intraoperative and post-operative analgesic use till 24 h.

Postoperative pain relief is important in procedures of the lower extremity. Several previous studies have evaluated the efficacy of intra-articular (IA) pethidine as a compound, which has local anesthetic and opioid agonist properties, on postoperative pain relief in arthroscopic knee surgery (AKS). This study compared the postoperative analgesic effect of pre- and post-surgical IA pethidine administration in AKS. ⋯ The present study shows that preemptive intra-articular pethidine 50 mg injection is more effective than preventive injection for postoperative pain relief at rest and joint movement in arthroscopic knee surgery.
