High-flow nasal oxygen therapy decrease the risk of mortality and the use of invasive mechanical ventilation in patients with severe SARS-CoV-2 pneumonia? A retrospective and comparative study of 265 cases.

INTRODUCTION: Corona virus disease (Covid-19) affects the airways and induces pulmonary lesions, patients with this disease require oxygen therapy as the disease progresses. Several oxygenation options have been used, l'HFNO had showed beneficial effects. THE OBJECTIVE OF THIS STUDY: To evaluate the efficacy of high-flow nasal oxygen HFNO versus non-invasive ventilation in COVID-19. METHODS: This is a retrospective and comparative study conducted over a period of 10 months from March 2020 to December 2020 and involving 600 patients hospitalized in the intensive care unit of the CHU Mohammed VI of Oujda for the management of acute respiratory failure caused by COVID-19. RESULTS: Out of 600 patients with acute respiratory failure, 265 patients were included in the analyses. 162 (61.10%) patients were treated with HFNO, the intubation rate was 49.7% (80 patients out of 162) of which 63 died intubated (78.8%). Concerning the 82 non-intubated patients, only 16 died (19.8%).The total number of patients who received NIV was 71 (26.8%), 33 (46.5%) required mechanical ventilation. In-hospital mortality in patients treated with NIV was 100%.The difference in mortality outcome between the two groups was significantly (P < 0.0001) reduced in HFNO. CONCLUSIONS: Treatment with high-flow oxygen improved survival in patients with acute hypoxemic respiratory failure compared with noninvasive ventilation, although no difference was observed in intubation rate.

The impact of mental health on COVID 19 disease progression: Case report.

It has been observed that mental disorder is associated with an aggravation of COVID 19 disease. A 44-year-old male patient, with no medical history, admitted to the emergency room for dyspnea, the exploration revealed SARS-COV-2 pneumonia. The patient was stable until he was aware of the death of his sister by COVID 19, he was admitted into the intensive care unit 24hours later in a serious condition after worsening of the inflammatory balance and pulmonary lesions. COVID 19 requires appropriate mental health management to help improve the prognosis of this disease.

Posterior Reversible Encephalopathy Syndrome Induced by an Acute Postinfectious Glomerulonephritis.

Posterior reversible encephalopathy (PRES) is a rare but a serious disease that affects the central nervous system. PRES is responsible for various but nonspecific neurological symptoms, including confusion, coma, and seizures as well as visual disturbances. Diagnosis is made using cerebral MRI which typically shows at the early stage, bilateral symmetrical parietooccipital hyperintensities on T2 and fluid-attenuated inversion recovery (FLAIR) sequences. Case study. In this article, we base our research on a case study that includes, as a population sample, a 9-year-old boy who suffers from an acute postinfectious glomerulonephritis and arterial hypertension. Two days before diagnosis, he developed confusion with generalized tonic-clonic attacks. His blood pressure was 180/80 mmHg. A cerebral computed tomography made in emergency showed cerebral edema. It was supplemented by magnetic resonance imaging which revealed cortical and posterior cortical lesions which appear as hypointense on T1 and hyperintense on T2 and Flair. An MRI control was performed 40 days later which shows a clear improvement of the occipital lesions. PRES is a radioclinical syndrome characterized by the association of variable neurological signs which reversibility is conditioned by the early diagnosis and the correction of the contributing factors.
