Rift valley fever (RVF) viral zoonotic disease steadily circulates in the Mauritanian animals and humans: A narrative review.

Background and Aim: Rift valley fever (RVF) virus (RVFV) is reportedly steadily circulating in Mauritania being repeated in 1987, 2010, 2012, 2015, and 2020. Mauritania seems a preferred niche for RVF virus due to its persistent outbreak there. Lately, nine Mauritanian wilayas confirmed 47 (23 fatalities with 49% CFR) human cases between August 30 and October 17, 2022. Most of the cases were largely among livestock breeders associated with animal husbandry activities. The review aimed at understanding the origin, cause, and measures to counter the virus. Methods: The facts and figures from the various published articles sourced from databases including Pubmed, Web of Science, and the Scopus as also some primary data from health agencies like WHO, CDC, and so forth were evaluated and the efficacy of countermeasures reviewed. Results: Among the reported confirmed cases, it was found that 3-70 year age-group males outnumbered the females. Deaths after fever occurred primarily due to acute hemorrhagic thrombocytopenia. Human infections often occurred through zoonotic transmission mainly through mosquitoes in the population contiguous to cattle outbreak, a conducive site for local RVFV transmission. Many transmission cases were through direct or indirect contact with blood or organs of the infected animal. Conclusion: RVFV infection was predominant in the Mauritanian regions bordering Mali, Senegal, and Algeria. High human and domesticated animal density as also the existing zoonotic vectors further contributed to RVF virus circulation. Mauritanian RVF infection data confirmed that RVFV was zoonotic that included small ruminants, cattle, and camel. This observation hints at the role of transborder animal mobility in RVFV transmission. In light of this, preventive approaches with effective surveillance and monitoring system following the One Health model is extremely beneficial for a free and fair healthy world for all.

Comparative study of epidural fentanyl with bupivacaine and epidural tramadol with bupivacaine for postoperative pain management in orthopedic lower limb surgeries

Introduction: Pain is a complex subjective sensation that is difficult to quantify in a repeatable manner. Surgical pain is observed to be more intense post-surgery and then fades in the next 24 h. Epidural anesthesia/analgesia is the most widely used technique for lower limb surgeries because of its good sensory and motor block property, reduces stress response, and maintains sufficient spontaneous respiration and hemodynamic stability. Materials and Methods: The study looked at 100 individuals between the ages of 20 and 60 who underwent elective lower limb surgery and were classified as ASA I and II. The patients were split into two 50-person groups. The adverse effects of nausea, vomiting, respiratory depression, urine retention, and pruritus, as well as the quality and duration of postoperative analgesia, were investigated. The patient was monitored for 48 h after surgery. Results: A total of 100 patients were included in the study, where the least age of the patient was 19 years and the greatest age was 75 years. In group T, maximum patients belong to the age group of 26–35 years, whereas in group F maximum patients belong to the age group of 36–45years. In group T, 41 (82%) were males and 9 (18%) were females. In group F, 37 (74%) were males and 13 (26%) were females. Conclusion: Our findings show that epidural tramadol and epidural fentanyl are equally effective, except for fentanyl’s shorter duration of action. Fentanyl also has a moderate sedative effect, which is beneficial in the postoperative period.
