RESUMEN
Background: COVID-19 (SARS-CoV-2/2019-nCoV) is now a major public health threat to the world. Olfactory dysfunctions (ODs) are considered potential indicating symptoms and early case identification triaging for coronavirus disease 2019 (COVID-19). The most common reported comorbidities are diabetes mellitus, chronic lung disease, and cardiovascular disease. The objective of this study was to evaluate prevalence of different types of smell disorders in patients with laboratory-confirmed COVID-19 infection and impact of involved systemic diseases. Methodology: A cross-sectional retrospective study has been done for patients with laboratory-confirmed COVID-19 infection (mild-to-moderate). The data collected from patient's files and developed online electronic questionnaire (WhatsApp) based on the patients most common and recurrent reported data including: a) symptoms of olfactory dysfunction and associated covid19 symptoms fever and headache, cough, sore throat, pneumonia, nausea, vomiting and diarrhea, arthralgia and myalgia and taste dysfunction. b) Associated systemic diseases including: diabetes, hypertension, asthma, chronic renal disease, chorionic liver disease and hypothyroidism. Results: Of 308 patients confirmed with Covid-19 infection, (72.4%) developed OD distributed as follows; complete anosmia (57.8%), troposmia (8.4%), hyposmia (2.9%), partial anosmia (2.6%) and euosmia (0.6%). Significantly increased prevalence of diabetes, hypertension asthma in the group with olfactory dysfunction (p < 0.001), chronic liver disease (p = 0.005), and hypothyroidism (p = 0.03). Conclusion: The development of ODs after Covid-19 infection was associated with mild disease form and lower hospitalization. In addition, it showed significant relationship with preexisting systemic diseases. Anosmia is the common modality of ODs.
RESUMEN
OBJECTIVE: To evaluate the efficacy and safety of preoperative duloxetine on postoperative pain management after gynecologic laparoscopic surgeries. METHODS: A systematic search was done in Cochrane Library, PubMed, ISI web of science, and Scopus from inception to September 2021. We selected randomized clinical trials (RCTs) that compared preoperative duloxetine (intervention group) versus placebo (control group) among women undergoing gynecologic laparoscopic surgeries. Our primary outcomes were pain scores evaluated by the Visual Analog Scale (VAS) at 2, 6, 12, and 24 h postoperatively. Our secondary outcomes were the time required for the first analgesic request in minutes, postoperative analgesic consumption in milligrams, length of hospital stay in days, and side effects. RESULTS: Four RCTs with a total number of 244 patients were included in our systematic review and meta-analysis. We found duloxetine was linked to a significant reduction in VAS pain scores at different time intervals. The first analgesic request was significantly earlier in the placebo group than in the duloxetine group (p = 0.03). In addition, duloxetine significantly reduced the postoperative analgesic consumption compared to placebo (MD= -41.97, 95% CI [-53.23, -30.72], p<0.001). However, both groups did not differ in the length of hospital stay and side effects. CONCLUSIONS: Duloxetine administration prior to gynecological laparoscopic surgeries is safe and effective in improving postoperative pain and analgesia.
