Perioperative results of radical cystectomy after neoadjuvant chemotherapy according to the implementation of ERAS pathway.

BACKGROUND: The effect of ERAS protocols in a population of radical cystectomy (RC) patients fit for neoadjuvant chemotherapy has not been specifically explored. OBJECTIVE: To compare perioperative outcomes of open RC according to the application of an ERAS protocol in a population of patients treated by cisplatin-based NAC. METHODS: All consecutive patients treated by NAC and RC between 2016 and 2019 were included. The ERAS pathway was implemented in June 2018 and followed the EAU recommendations. All data were prospectively collected. Patients' characteristics, operative outcomes, length of stay (LOS), complication rate according to Clavien-Dindo and pathological results were compared between pre- and post-ERAS. Statistical analysis was performed using R. RESULTS: In total, 79 patients were included, 29 in the ERAS group and 50 in the non-ERAS group. A median number of 19 out of 22 ERAS criteria were followed. Mean number of NAC cycles was 4.45 vs. 4.79 in the pre- and post-ERAS groups respectively (P=0.24). Median time between NAC and RC was 3.8months. Thirty-eight percent vs. 48% of patients received an ileal neobladder in the pre- and post-ERAS group respectively (P=0.51). No differences were observed regarding operative time, blood loss or operative transfusion rates. LOS was drastically reduced in the ERAS period (18.94 vs. 12.10days, P<0.001) as well as major (>Clavien 2) complications rate (65% vs. 28%, P=0.004). CONCLUSION: ERAS drastically reduced the LOS and the rate of high-grade complications and can be effectively applied to patients receiving NAC without delaying RC.

Comparison of men with impaired fasting glycaemia to controls and to diabetic subjects with fasting glycaemia from 7.0 to 7.7 mmol/l: clinical, nutritional and biological status.

OBJECTIVE: To compare medical history, clinical, nutritional and biological status of non-diabetic men to subjects with impaired fasting glycemia (glycemia 6.1-6.9 mmol/l) and to newly diagnosed type 2 diabetic subjects (7.0-7.7 mmol/l) according to the criteria proposed by the American Diabetes Association. METHODS: Cross-sectional study of a cohort of 29,992 men, who were volunteers for a free periodic check-up offered by their medical insurance. Medical history, lifestyle and nutritional habits were recorded using a self-administered questionnaire. Clinical and biological data were also studied. To compare the three groups of subjects - normal, impaired fasting glycemia and newly diagnosed diabetics - three age stratified samples were randomly designed. RESULTS: Most of the well-known risk factors for developing type 2 diabetes mellitus such as overweight, abdominal obesity, familial history of diabetes mellitus, over-consumption of fat and alcohol were present in the group with impaired fasting glycaemia which presented the same risk factors as the group of subjects with fasting glycaemia from 7.0 to 7.7 mmol/l, but to a lesser degree. Hypertension was present in more than 50% of the subjects with impaired fasting glycaemia. CONCLUSION: In this cross-sectional study, impaired fasting glycaemia is associated with the risk factors of type 2 diabetes mellitus. The subjects with impaired fasting glycaemia should be considered at risk for cardiovascular disease and might take advantage from early specific intervention about their lifestyle.

Recovery after anaesthesia for pulmonary surgery: desflurane, sevoflurane and isoflurane.

We have studied maintenance and recovery profiles after general anaesthesia with sevoflurane, desflurane and isoflurane in 100 patients undergoing pulmonary surgery. End-tidal concentrations of anaesthetic required to maintain mean arterial pressure and heart rate within 20% of baseline values were 1.4 +/- 0.6% for sevoflurane, 3.4 +/- 0.9% for desflurane and 0.7 +/- 0.3% for isoflurane. The three anaesthetics had comparable haemodynamic effects and arterial oxygenation during one-lung ventilation. Emergence was twice as fast with desflurane than with sevoflurane or isoflurane (mean times to extubation: 8.9 (SD 5.0) min, 18.0 (17.0) min and 16.2 (11.0) min for desflurane, sevoflurane and isoflurane, respectively). Early recovery (Aldrete score, cognitive and psychomotor functions) was also more rapid after desflurane. In pulmonary surgery, desflurane, but not sevoflurane, allowed more rapid emergence and earlier recovery than isoflurane.

[Exclusive use of calcium channel blockers and cardioselective beta-blockers in the pre- and per-operative management of pheochromocytomas. 70 cases]. / Utilisation exclusive des inhibiteurs des canaux calciques et des beta-bloquants cardio-sélectifs dans la prise en charge péri et per-opératoire des phéochromocytomes. A propos de 70 cas.

The pre and intraoperative use of calcium channel blockers (CCB) has been suggested for the management of either eutopic or ectopic pheochromocytomas. We report our experience of 70 pheochromocytomas, operated between 1988 and 1996 and managed with CCB, especially nicardipine. 59 were hypertensive (84.2%). Preparation consisted of nicardipine in 61 patients or another CCB in 9 cases with duration ranging from 24 hours to several weeks depending on plasma volume and blood pressure control. Intraoperatively, nicardipine infusion was started after intubation, adjusted according to systolic blood pressure (SBP) and stopped before ligation of the tumor venous drainage. Increases in SBP greater than 200 mmHg were observed in 10 patients and were effectively controlled by nicardipine in all cases. In 16 patients, the S > BP remained less than 150 mmHg throughout anesthesia. Heart rate greater than 100 b p m occureed in 51 patients and was easily controlled with esmolol whenever used (n = 27). Arythmias were unfrequent (n = 4) and required treatment in only one case. This study confirms the ability to adequately manage pheochromocytomas with the use of nicardipine as sole vasodilating agent.

[The YAG laser in children's conservative dentistry. Preliminary report]. / Le laser Yag en odontologie conservatrice infantile. Rapport préliminaire.

The authors give a preliminary report of the use of a high-power (60 W) pulsed Yag laser in conservative odontology. A purely experimental phase involving laser shots to 164 freshly extracted teeth preceded the clinical evaluation. Sterilization was obtained in all cases. Histopathological sections showed that there was destruction of caries with carbonization, and melting of the superficial layer despite complete preservation of the pulp. The clinical study which followed involved 28 milk teeth. In 9 cases local anesthesia was of no value. In all cases there was vaporization of the pathological dentition and vitrification of the superficial dentin layer. Pulp vitality tested before and sometime after the procedure was preserved in all cases. These are the results reported here with a review of the probable future possibilities of the Yag laser.
