Predictive factors of six-week mortality in critically ill patients with SARS-CoV-2: A multicenter prospective study.

OBJECTIVE: The objective of the study is to identify the risk factors associated with mortality at six weeks, especially by analyzing the role of antivirals and munomodulators. DESIGN: Prospective descriptive multicenter cohort study. SETTING: 26 Intensive care units (ICU) from Andalusian region in Spain. PATIENTS OR PARTICIPANTS: Consecutive critically ill patients with confirmed SARS-CoV-2 infection were included from March 8 to May 30. INTERVENTIONS: None. VARIABLES: Variables analyzed were demographic, severity scores and clinical condition. Support therapy, drug and mortality were analyzed. An univariate followed by multivariate Cox regression with propensity score analysis was applied. RESULTS: 495 patients were enrolled, but 73 of them were excluded for incomplete data. Thus, 422 patients were included in the final analysis. Median age was 63 years and 305 (72.3%) were men. ICU mortality: 144/422 34%; 14 days mortality: 81/422 (19.2%); 28 days mortality: 121/422 (28.7%); 6-week mortality 152/422 36.5%. By multivariable Cox proportional analysis, factors independently associated with 42-day mortality were age, APACHE II score, SOFA score at ICU admission >6, Lactate dehydrogenase at ICU admission >470U/L, Use of vasopressors, extrarenal depuration, %lymphocytes 72h post-ICU admission <6.5%, and thrombocytopenia whereas the use of lopinavir/ritonavir was a protective factor. CONCLUSION: Age, APACHE II, SOFA>value of 6 points, along with vasopressor requirements or renal replacement therapy have been identified as predictor factors of mortality at six weeks. Administration of corticosteroids showed no benefits in mortality, as did treatment with tocilizumab. Lopinavir/ritonavir administration is identified as a protective factor.

Stroke and pulmonary thromboembolism after a long flight.

In the economy class syndrome (ECS) the patient presents a deep venous thrombosis (DVT) with or without pulmonary thromboembolism (PTE) during or after a long trip as a result of prolonged immobilization. Economy class stroke syndrome is an infrequent ECS variant in which ischemic stroke is associated with a patent foramen ovale (PFO). Few cases have been published in the literature to date. We present a patient who suffered a PTE and an ischemic stroke immediately after a transoceanic flight. A 36-year-old woman with no significant medical or familial history flew economy class from Lima, Peru, to Madrid, Spain. On disembarkation she presented sudden dyspnea and a depressed level of consciousness, global aphasia, and right hemiparesis. A pulmonary scintigraphy showed a PTE and a cranial MRI revealed an ischemic infarct in the left middle cerebral artery territory. We simultaneously performed a transesophageal echocardiography and a transcranial Doppler and observed a massive right-to-left shunt through a PFO. The patient was a heterozygous carrier of the C46T mutation of coagulation factor XII. The appearance of a stroke following a long trip is suggestive of paradoxical embolism through a PFO, mainly if it is associated with a DVT and/or a PTE. The cause of the initial event, the DVT, could be a prothrombotic state.

Acute paroxysmal dystonia induced by fluoxetine.

We report a case of a 32-year-old woman who developed paroxysmal episodes of right hemidystonia 2 days after taking fluoxetine. The attacks subsided 2 days after fluoxetine was withdrawn and did not recur afterwards. To our knowledge, this is the first report of paroxysmal dystonia induced by fluoxetine.

[An unusual presentation of herpetic encephalitis]. / Encefalitis herpética de presentación atípica.

INTRODUCTION: Herpetic encephalitis (HE) is the commonest cause of acute sporadic encephalitis in the United States and Europe. In 20% of cases, the clinical course is atypical and this may lead to delay in diagnosis and treatment. CLINICAL CASE: A 24 year old patient presented with aseptic meningitis, which had been present for the previous 10 days and which then became complicated by fever and aphasia. The cerebrospinal fluid (CSF) showed marked pleocytosis and increased protein. Cerebrospinal puncture was found to be positive for DNA of the herpes simplex virus. Magnetic resonance (MR) imaging showed a temporal lesion with intense uptake of contrast. Treatment was started with acyclovir and the patient improved over the days following this. CONCLUSIONS: At present the diagnosis of herpetic encephalitis is based on polymerase chain reaction (PCR) studies of the CSF and MR imaging. The correlation between patients with HE with cerebrospinal puncture showing positive for herpes and alterations on MR is 89%. In view of the 20% of atypical forms, a high degree of clinical suspicion is necessary to try to obtain early diagnosis and treatment.

[The association of the Eaton-Lambert myasthenic syndrome and subacute cerebellar degeneration of nonparaneoplastic origin]. / Asociación de síndrome miasteniforme de Eaton-Lambert y degeneración cerebelosa subaguda de origen no paraneoplásico.

A 52-year-old male with Eaton-Lambert syndrome associated to seven years subacute cerebellar degeneration of non paraneoplastic origin is presented. Immunosuppressive treatment with azathioprine allowed the neuromuscular symptoms to be controlled although no appreciable effects were observed in the cerebellar symptoms which remained stable.
