RESUMEN
BACKGROUND: Increasing number of patients with COVID-19-associated mucormycosis have been reported, especially from India recently. We have described a patient with COVID-19-associated mucormycosis and, searched and analyzed current medical literature to delineate the characteristics of COVID-19-associated mucormycosis. METHOD: We reported a patient developed mucormycosis during post-COVID period. We searched literature to describe the incidence, clinical features, and outcomes of COVID-19-associated mucormycosis. Demographic features, risk factors, clinical features, diagnostic methods, treatment and outcome were analyzed. RESULTS: We describe a 54-year-old male, hospitalized due to severe COVID-19 pneumonia. He was given long-term, high doses of systemic steroids. He developed maxillo-fascial mucormycosis and died of sepsis. Our literature search found 30 publications describing 100 patients including present case report. The majority (n = 68) were reported from India. 76% were male. The most commonly seen risk factors were corticosteroid use (90.5%), diabetes (79%), and hypertension (34%). Also, excessive use of broad-spectrum antibiotics were noted in cases. Most frequent involvements were rhino-orbital (50%), followed by rhino-sinusal (17%), and rhino-orbito-cerebral (15%). Death was reported as 33 out of 99 patients (33,3%). CONCLUSIONS: Steroid use, diabetes, environmental conditions, excessive use of antibiotics, and hypoxia are main risk factors. Despite medical and surgical treatment, mortality rate is high. A multidisciplinary approach is essential to improve the conditions facilitating the emergence of COVID-19-associated mucormycosis.

OBJECTIVES: The aim of this study was to determine whether erythropoietin (EPO) can enhance rotator cuff healing in rats as measured by histological analysis and biomechanical testing. METHODS: A total of 72 rats were included in this study. In the control group (n = 24), repair was performed without EPO injection. In the local group (n = 24) EPO was injected in the repair site. In the systemic group (n = 24) EPO was administered as an intraperitoneal injection every day for 10 days after repair. Rats were euthanized on day 10 (n = 12 from each group) and day 28 (n = 12 from each group). Histopathological (n = 6) and biomechanical examinations (n = 6) were done. RESULTS: Biomechanical results reveal that the maximum load to failure values of the early control group were statistically lower than those of the early systemic group (p = 0.006). Comparing the the total Bonar values histopathologically reveal that the early systemic group was statistically higher than those of the early local group (p = 0.043). The late control group was statistically higher than those of the late local group (p = 0.003) and the late systemic group (p = 0.034). The late systemic group was statistically higher than those of the late local group (p = 0.003). CONCLUSIONS: EPO application had a positive effect biomechanically in the early euthanized group and histopathologically in the late euthanized group.
