Methods Sixty ASA I primiparae aged 22-29 yr, weighing 46 - 83 kg, scheduled for elective caesarean section were randomized into epidural anesthesia group (EA, n = 30) and combined spinal-epidural anesthesia group ( CSEA, n = 30). All patients were premedicated with intramuscular atropine 0. 5 mg and phenolbarbital 100 mg. In CSEA group a 26 G/16 GChina Medical Abstracts (Surgery) single use spinal/epidural needle (B- D) was used. Spinal and/or epidural anesthesia was performed at L2-3 interspace and a catheter was threaded into the epidural space cephalad for 3 - 5 cm in both groups. In EA group a loading dose of 12 - 16 ml 2 % lidocaine was given and an additional 6-8 ml 2% lidocaine was injected when anesthesia became indadequate during the operation. In CSEA group 2.0-2.5 ml hyperbaric 0.5% bupivacaine (10 - 12.5 mg) was given展开更多

The aim of this study is to determine the morbidity and mortality of COVID-19 patients admitted with ARF to the intensive care unit of the Grand H?pital Est Francilien (GHEF) according to the waves and variants. Methods: Cross-sectional observational study of COVID-19 patients with ARF admitted to the intensive care unit of the GHEF site in Meaux covering the period from March 1<sup>st</sup> 2020 to December, 31<sup>st</sup> 2021. Per-hospitalisation and outcome data were collected and analysed with SPSS version 25.0 software using the Chi-square or Fischer’s exact test or Student’s t-test and logistic regression for p Results: A total of 86 patients were included. The mean age was higher (70 ± 8.5) in patients in the fourth wave than in the other waves (p = 0.015), with male predominance in all waves without significant difference. Co-morbidities: hypertension, diabetes, heart disease, dyslipidaemia and arrhythmia complete with fibrillation were present in all waves. The majority of patients were classified as KDIGO 1 for the different waves (1st: 61.9%, 2nd: 86.5%, 3rd: 80%, and 4th: 75%), with the same trend according to variant (alpha: 80%, beta: 75%, delta: 81.3%, omicron: 75%). Mortality by the wave was: 1st: 28.5%, 2nd: 37.5%, 3rd: 23% and 4th: 11%) and by variant: alpha: 24.2%, beta: 44.8%, delta: 20.7%, omicron: 10.3%). Overall mortality was 33.7%. Case fatality was higher in the fourth wave. Hypertension, shock, failure to recover renal function, acute lung oedema, ventilator-associated lung disease and hyperkalaemia were factors associated with mortality (p Conclusion: Acute renal failure is common in COVID-19 patients admitted to the intensive care unit, and mortality is not negligible. The beta variants and the second wave presented more cases of renal impairment, although the mechanism is still unknown. Further studies are needed to understand this mechanism and perhaps to be able to identify the cause.展开更多

This study aimed to describe the impact of COVID-19 vaccination on the prognosis of hospitalized patients. Methods: This was a retrospective cohort study of patients admitted to the Centre Hospitalier Régional Lomé Commune (Togo) between June 1, 2021 and May 31, 2022. Primary outcomes (admission to the intensive care unit and death) were presented with frequency and proportion. Mortality rates were presented by sociodemographic and clinical characteristics and compared by appropriate statistical tests. Factors associated with inpatient death were described by performing a Cox proportional hazard regression. Results: A total of 604 patients were hospitalized (50.0% women). The mean age was 54.03 ±17.1 years. Only 55 patients were fully vaccinated (9.1%). ICU admission was significantly more frequent in unvaccinated patients than in vaccinated ones (63.0% vs. 38.2%;p Conclusion: COVID-19 vaccination had a significant benefit for patients with COVID-19 infection in terms of reducing the risk of death. Based on real-world data from sub-Saharan Africa, this information can help optimize the benefit of COVID-19 vaccination by raising community awareness and increasing vaccine coverage while reducing hesitancy.展开更多

They represent approximately 2% of all laterocervical tumors and 6% to 85% of anomalies of the second branchial cleft. This anomaly of the second branchial cleft is a frequent reason for consultation in the pediatric population but is relatively rare in adults. We report the cases of two patients aged 23 and 34 years with no particular pathological history. They were presenting a laterocervical swelling, one right and the other left, painless, evolving for two years for the first and for 10 years for the second, gradually increasing in volume without any other associated signs the diagnosis of which after radiological exploration (ultrasound and CT scan) was that of an amygdaloid cyst. A cervicotomy with anatomopathological examination of the surgical specimen confirmed the diagnosis of the amygdaloid cyst. The objective is to analyze the anatomo-clinical and therapeutic particularities of this pathology and to compare it with data from the literature.展开更多
