RESUMEN
Background: This study finds the changes in the hematological parameters of healthy individuals to predict the immune status against coronavirus disease 2019 (COVID-19) among COVID -19 vaccinated and nonvaccinated individuals. Methods: A comparative cross-sectional study among 210 healthy individuals was conducted. All individuals were divided into three groups, that is, IgG positive, IgG negative, and IgG and IgM positive, based on ELISA. Data analysis was done using SPSS version 25 for Windows. Results: A statistically significant effect was found among the three groups in terms of mean levels of hemoglobin (Hb), hematocrit (Hct), mean corpuscular hemoglobin concentration (MCHC), red blood cells (RBC), RDW-CV, lymphocyte, neutrophil, eosinophils, and basophil count. The study also showed that 52.8% (n=74) had neither taken vaccination nor had any history of previous COVID-19 infection but were IgG antibody positive. Conclusion: There was a statistically significant difference among hematological parameters between immune and nonimmune groups, and it can predict the COVID-19 immune status.
RESUMEN
Introduction: Cerebral venous sinus thrombosis (CVST) is a rare but highly fatal neurological condition mostly caused by prothrombotic conditions like antiphospholipid syndrome, factor V Leiden, and G20210A prothrombin polymorphism. Snake bites are a rare cause of cerebral venous sinus thrombosis that must be recognized and treated promptly to improve survival. Case presentation: We present a case of a 25-year-old male who developed headaches and seizures following a Viper snake bite. The diagnosis was made based on a magnetic resonance venogram (MRV) showing transverse sinus thrombosis with sigmoid sinus stenosis. Initially, the patient was treated with antivenom and supportive treatment for disseminated intravascular coagulation (DIC). After the diagnosis of CVST, the patient was treated with rivaroxaban and levetiracetam. The patient improved within 1 week of treatment and was advised to follow up in 3 months. Conclusion: A high index of suspicion for cerebral venous sinus thrombosis is required if the patient presents with headaches, seizures, or abnormal vision following a snake bite. Early diagnosis and management can prevent further neurological damage.
