RESUMO
BACKGROUND: Taste disorders (TDs) have been reported to be very common in patients suffering from coronavirus disease 2019 (COVID-19), which is caused by the SARS-CoV-2 virus. In most of the hitherto conducted studies, a gustatory assessment was performed on the basis of surveys or self-reports by patients. The aim of our study was to undertake an objective assessment of four basic taste qualities by conducting tasting sessions that allowed detection thresholds in COVID-19 Tunisian patients and to study their associations with inflammation. METHODS: This analytical cross-sectional study was conducted on 89 patients aged between 21 to 70 years who had been diagnosed with COVID-19. We used Burghart taste strips to assess taste perception of the four taste qualities, i.e., sour, bitter, sweet, and salty. Serum levels of interleukin-1ß (IL-1ß), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), and C-reactive protein (CRP) were measured. RESULTS: Taste disorders were reported by 40.4% of the patients, while objective assessments revealed that 63.8% of participants were suffering from hypogeusia and/or ageusia. Sour taste was the most altered (70.8%) gustatory quality. Patients with severe COVID-19 had significantly lower sour and bitter taste scores when compared to patients with minor/moderate forms. There was no significant association between serum inflammatory markers and taste disorders. However, the relationship between bitter and sweet taste qualities and IL-1ß levels was significant (p = 0.018 and p = 0.041). CONCLUSIONS: Our results demonstrate the interest in the objective assessment of taste dysfunctions in COVID-19 patients.
RESUMO
The use of Cardiopulmonary bypass (CPB) and extracorporeal membrane oxygenator (ECMO) in patients suffering from Sickle cell disease (SCD) needs specific precautions. Whereas, no consensual protocols have been established to clarify therapeutic management. CASE REPORT A 7-year-old boy was admitted to the hospital for surgery of advanced endocarditis. Major dyspnea, hemodynamic distress and fever were noted on physical examination. Biological tests exploring anaemia revealed Haemoglobin (Hb) S levels of 39.1%. Echocardiography showed important right heart cavities dilation with multiple aortic vegetations. The child was accepted for emergent surgery. Ten minutes after anesthetic induction, serious hemodynamic distress was established. The patient was put on normothermic CPB when he received four packed red-blood-cell. After surgery, he was placed on ECMO support for 2 days than he succumbed. CONCLUSION Urgent cardiac surgery in patients suffering from SCD poses a major therapeutic dilemma. Multiplying case reports and encouraging prospective studies are necessary to define the right place of cardio-pulmonary assistance in treatment protocols for better management.

AIM: To compare efficacy of pain control, the consumption of local anaesthetics and opioids as well as the side effects between continuous epidural analgesia, patient controlled analgesia and patient controlled epidural analgesia in thoracic surgery. METHODS: Prospective randomised study included 66 patients who had thoracotomy. Patients were divided into 3 groups, to receive different pain control methods. Group 1 (n=22) received patient control analgesia Group 2 (n=22) received continuous epidural analgesia (Bupivacaine 0,125% + 5 microg/ml of Fentanyl) between 6 and 10 ml/h in order to obtain a T2 level Group 3 (n=22) received patient controlled epidural analgesia (Bupivacaine 0,08% + 3 microg/ml of Fentanyl) 6 ml/h and bolus of 5 ml. RESULTS: There was no difference between the three groups in age, delay of surgical operation and per operative morphine consumption. VAS was less at rest and after cough in patient group with patient controlled epidural analgesia. The difference was less significant in local anaesthetics and opioids consumption in patient with controlled epidural analgesia. CONCLUSION: The benefit of patient controlled epidural analgesia in thoracic surgery is proven by the following analgesic efficiency which allows good respiratory rehabilitation, decreasing the risk of drug toxicity by decreases consumption, weak hemodynamic effects and absence of motor block.

BACKGROUND: combination of ketamine may improve morphine patient controlled analgesia (PCA) but clinical results are still equivocal. AIM: The authors designed a powerful study to evaluate this hypothesis after major abdominal surgery. METHODS: 138 patients undergoing abdominal surgery participated in the randomized double blind study. Patients were allocated to two groups: M-group: morphine 0.5 mg/ml + placebo in PCA and MK-group: morphine 0.5 mg/ml + ketamine 0.5 mg/ml with the same bolus dose and lock out time. The patients were evaluated during 48 hours by visual analog scale (VAS), simplified verbal scale (SVS). Side effects and amount of morphine used were monitored. RESULTS: The two groups are comparable for demographic data and surgery characteristics. From the 24th hour, morphine consumption was significantly lower in the MK-group. At 48 hours after surgery, the amount of morphine received in the MK-group was significantly lower than in the M-group (48 vs 66 mg, p < 0.001). The average value of VAS was lower in the MK-group from the 12th hour at rest and 20th hour during mobilization. SVS was significantly lower for the MK-group after the 12th postoperative hour. The incidence of respiratory depression was higher in the M-group: 4 vs none in the MK-group. The incidence of nausea, vomiting and pruritus was halved in the MK-group (p < 0.04). CONCLUSION: The combination of ketamine with morphine in PCA after major abdominal surgery offers a reduction of the morphine consumption, a reduction of pain scores and a decrease in the incidence of adverse effects.
