BackgroundFlexible laryngeal mask airway may be used instead of the endotracheal tube in children presented for elective repair of tongue trauma, as it may shorten the time for extubation and recovery with the amelioration of stress response to airway management.ObjectivesThis study aimed to evaluate the extubation time and hemodynamic response to the endotracheal tube or flexible laryngeal mask airway in children presented for tongue trauma repair.MethodsThe study recruited 90 children presented for elective repair of tongue trauma that were randomly assigned into the following groups: the ETT group for which the airway was controlled by a cuffed endotracheal tube and the LMA group for which the airway was controlled by a flexible laryngeal mask. The intubation time, surgical time, total anesthesia time, extubation time, recovery time, changes in the hemodynamic parameters, and the incidence of complications were measured.ResultsThe use of flexible laryngeal mask airway instead of endotracheal tube significantly decreased the extubation time to 7.47 ± 2.74 min (P < 0.0001) and the recovery time to 52.67 ± 11.16 min (P = 0.001) while no significant differences were observed in the intubation time (P = 0.874), surgical time (P = 0.411), and total anesthesia time (P = 0.725). In addition, the changes in the hemodynamic parameters were significantly lower with flexible laryngeal mask airway both during airway securing and at the start of the surgery (P < 0.05). Moreover, it significantly decreased the incidence of postoperative cough, stridor, and sore throat (P = 0.039, 0.006, and 0.027, respectively).ConclusionsThe flexible laryngeal mask airway can be used instead of the endotracheal tube in children undergoing the repair of tongue trauma, as it decreases the extubation time, recovery time, and hemodynamic changes to the airway control.

Background and objectives: Pancreatic adenocarcinoma represents one of the common malignancies with a relatively poor prognosis. However, early detection of this type of cancer may prove to be curable. Recent advancements in the radiological techniques might represent a hope for the early diagnosis and prediction of prognosis of pancreatic adenocarcinoma. This study aimed to assess the prognostic value of the primary tumor volumetric parameters obtained from FDG PET/CT first stage for the overall survival (OS) and progression-free survival (PFS) of patients with pancreatic adenocarcinoma and to explore the possible correlation between serum matrix metalloproteinase-2 (MMP-2) and the patients’ characteristics. Methods: Fifty patients with pancreatic adenocarcinoma were subjected to FDG PET/CT scan. The SUVpeak, SUVmax, and the metabolic tumor volume (MTV) were determined, as well as the SUVmean of the liver. Moreover, serum levels of MMP-2 were assessed. Follow-up of the patients was carried out for sixty months with determination of PFS and OS. Results: Peak SUV ≥ 3.9 was significantly correlated with the primary pancreatic lesions’ mean total glycolytic activity of >92 g, and MTV and was directly correlated with mortality. There was a positive correlation between peak SUV ≥ 3.9 and 50% SUVmax threshold > 82. Moreover, there was significant correlation between the total glycolytic activity and the studied clinicopathologic factors, except the age and sex of the patients and ECOG performance status. In addition, FDG uptake and the tumor glycolytic activity were substantially linked with a shorter PFS. Similarly, a strong correlation was found between MTV and PFS. Serum MMP-2 levels showed a significant relationship with the performance status, tumor stage, SUVmax threshold, and the glycolytic activity. Conclusions: Peak SUV, main lesion SUVmax, serum MMP-2, and the tumor glycolytic activity are good predictors of PFS of patients with pancreatic adenocarcinoma.

Background: Surgery and anesthesia are sources of stress to the patients. Inflammatory reactions to this stress have adverse effects on wound healing and remote organs in addition to long-term sequels e.g. adhesion formation. We compared the effects of dexmedetomidine and ketamine on perioperative level of serum inflammatory biomarkers including tumor necrosis factor-α, interleukin-6, and C- reactive protein. Methods: We included Seventy-five patients, aged 30-60, ASA I–II, and scheduled for laparoscopic hysterectomy. Patients were randomized to receive intraoperative ketamine (bolus dose 0.25 mg/kg then continuous infusion 250 µg/kg/h), dexmedetomidine (1µg/kg bolus dose then continuous infusion 0.5 µg/kg/h), or placebo. The primary outcome was to measure serum level of inflammatory biomarkers. Hemodynamic parameters, Recovery time, and complications within 24 hours postoperative were recorded.Results: Whilst there was significant increase in concentrations of inflammatory biomarkers 6 and 24 h postoperative in all groups, there were significant differences between ketamine and dexmedetomidine group as compared to control group with no significant differences between ketamine and dexmedetomidine group. As regard hemodynamic parameters, there were significant increase in ketamine group and decrease in dexmedetomidine group as compared to base line with no need for medical intervention. There was delayed recovery in ketamine group versus control and dexmedetomidine group (24.3 ± 6.4, 12.6 ± 2.0, 13.5 ± 3.3 min respectively; P < 0.001). More complications were reported in ketamine group but did not reach statistical significance. Conclusion: Dexmedetomidine and ketamine are comparable as regards attenuation of perioperative inflammatory response. However, dexmedetomidine has a favorable safety profile.Trial registry number is (PACTR201910617459894: date of registration 10/24/2019)

Background: For pregnant women who require an emergency cesarean section (CS), extending labor epidural analgesia as quickly as feasible to good quality anesthesia is a critical issue. This indicates the presence of functional labor epidural analgesia and reduces the need for general anesthesia. Addition of magnesium increases anesthetic and analgesic qualities of epidural anesthesia. Objectives: The purpose of this trial was to assess the role of adding magnesium sulfate (MgSO4) with levobupivacaine to speed up the conversion of labor epidural analgesia into enough anesthesia for emergency CS. Methods: Fifty parturients were randomly assigned to receive 19.5 mL of levobupivacaine 0.5% with either 0.5 mL of normal saline 0.9% (Group I) or 0.5 mL of MgSO4 10% (Group II) after receiving labor epidural analgesia. We documented the onset of block (loss of pinprick to T6), number of patients needing additional analgesia, the time needed for sensory and motor blockade to recover, and the adverse effects. Results: The frequency of patients receiving intraoperative supplements was comparable in the study groups (P = 0.491), although the onset of the block was faster in Group II than in Group I (P = 0.000*). Group II took substantially longer to recover from sensory and motor blockade than Group I (P = 0.001* and P = 0.001*, respectively). In both groups, the occurrence of adverse events was similar. Conclusions: Adding 50 mg of MgSO4 to levobupivacaine 0.5% accelerated the epidural top, and both sensory onset and motor blocks period were prolonged as compared to levobupivacaine alone when extending epidural analgesia for emergency CS.

Background and Objectives: Diarrhea induced by chemotherapy may represent a life-threatening adverse effect in cancer patients receiving chemotherapy. FOLFOX, an effective treatment for colon cancer, has been associated with diarrhea with high severity, particularly with higher doses. Management of diarrhea is crucial to increase the survival of cancer patients and to improve the quality of life. Glutamine is an abundant protein peptide found in blood and has a crucial role in boosting immunity, increasing protein anabolism, and decreasing the inflammatory effects of chemotherapy on the mucosal membranes, including diarrhea. This study aimed to provide evidence that parenteral L-alanyl L-glutamine dipeptide may have a positive influence on the incidence of diarrhea, treatment response, and the overall survival in colon cancer patients treated with modified FOLFOX-6 (mFOLFOX-6). Materials and Methods: Forty-four stage II and III colon cancer patients were included in this study where they were treated with the standard colon cancer chemotherapy mFOLFOX-6 and were randomly allocated into glutamine group and placebo group, each of 22 patients. Results: L-alanyl L-glutamine dipeptide was found to be significantly effective in decreasing the frequency and severity of diarrhea when compared to the placebo group, particularly after four and six cycles of mFOLFOX-6. There was no significant difference between the studied groups regarding to the overall survival. Conclusion: L-alanyl L-glutamine dipeptide can be considered as an add-on with chemotherapy to improve the quality of life and the overall survival of colon cancer patients.
