[COVID-19 associated sino-orbital mucormycosis]. / COVID-19-assotsiirovannyi sinoorbital'nyi mukormikoz.

OBJECTIVE: To analyze the dynamics of symptoms in patients with COVID-19 associated sino-orbital mucormycosis. MATERIAL AND METHODS: We describe a series of 13 patients with COVID-19 associated sino-orbital mucormycosis aged 43 to 80 years diagnosed from August to October 2021. All of the patients had a severe disease and required noninvasive ventilation or intubation and administration of dexamethasone. 12 out of 13 patients (92.3%) suffered from diabetes mellitus. Symptoms of fungal infections of the nose and paranasal sinuses appeared in the interval from 7 to 25 days of hospital stay, most often in the second week (from 8 to 12 days). According to clinical and CT features the patients were divided into three groups, combining similar phenotypes of the disease. Group 1 - 1 patient with sinonasal mucormycosis, destruction of the alveolar ridge and the hard palate. Group 2 - 12 patients with sino-orbital mucormycosis. We noted, that in cases of bilateral sinus lesions orbital complications were unilateral in all patients, on the side of more severe lesion. Group 2 was divided into 2 subgroups: subgroup 2a included 2 patients with the superior orbital fissure syndrome: ptosis, proptosis, ophthalmoplegia, periorbital pain, pain or hypoesthesia of half face; subgroup 2b included 10 patients with the orbital apex syndrome, who, in addition to the above symptoms, had loss of vision and conjunctival chemosis. Group 3 - rhino-sino-cerebral mucormycosis. 2 patients from subgroup 2b were transferred to this group due to the intracranial spread of the process and focal neurological symptoms. CONCLUSION: Clinical forms of mucormycosis reflect successive stages of invasive spread of fungi.

[Postcovid sino-orbital mucormycosis: a case report]. / Sluchai postkovidnogo sinoorbital'nogo mukormikoza.

We describe a case of postcovid sino-orbital mucormycosis in a 74-year-old patient with diabetes mellitus. Orbital symptoms appeared after discharge from the covid hospital, in the third week of the disease and were represrnted by ptosis, proptosis, ophthalmoplegia, blindness and pain in the right eye, numbness of the right half of the face, edema of the periorbital region and cheek. The diagnosis of mucormycosis was confirmed by fluorescence microscopy of the discharge from the middle nasal meatus. SCT of the paranasal sinuses revealed pansinusitis with predominant destructive changes in the right maxillary, ethmoid and sphenoid sinuses. The patient underwent emergency endoscopic debridment, orbital decompression, orbitotomy; treatment with amphotericin B intravenously was started. 10 days after due to the deterioration of the patient's condition, more aggressive debridment of paranasal sinuses was performed: right maxillary sinus anterior, posterior and medial walls resection, medial orbital wall resection, necrectomy of the nasal cavity, paranasal sinuses, orbit, pterygopalatine fossa. Antifungal treatment was continued in the postoperative period. The patient was discharged on the 22nd day of stay in the ENT hospital.

Post COVID-19 Sino-Orbital Mucormycosis: A Therapeutic Challenge

Objective: To determine the frequency of sino-orbital mucormycosis outcomes in diagnosed patients of COVID-19 and its association with the duration of the disease. Study Design: Case series. Place and Duration of Study: Armed Forces Institute of Ophthalmology, Pak Emirates Military Hospital, Rawalpindi, from Feb to Jul 2021. Methodology: A sample size of 20 was calculated using WHO calculator. Diagnosed patients of COVID-19 who fulfilled the inclusion criteria were selected through consecutive sampling technique. The mode of presentation, in-depth imaging findings, associated co-morbidities and management/follow up details were collected. Results: Total 20 patients were included in study. There were 12 (60%) male and 8 (40%) female. Mean age of patients was 60.4 ± 9.8 years. Outcomes of study were treatment, still of follow up, mortality and mortality with sepsis, survival and exenteration (15%, 15%, 25%, 5%, 25% 15% respectively). Among all the patients, 2(10%) patients showed intraconal and extraconal orbital involvement, 9 (45%) showed left, 8 (40%) showed right and 1(5%) showed both orbits involvement. Outcomes of sino-orbital mucormycosis showed significant association with COVID-19 duration (p=0.03). Conclusion: Sino-Orbital mucormycosis is a common and potentially life-threatening complication of COVID-19. Early initiation of anti-fungal treatment as well as surgical intervention are key to decrease both the mortality and morbidity associated with the disease.

Outbreak of Mucormycosis in Coronavirus Disease Patients, Pune, India.

We provide an overview of the epidemiology and clinical course of mucormycosis in the coronavirus disease (COVID-19) pandemic era. We conducted a retrospective chart review of 178 patients with clinical or diagnostic, endoscopically or histopathologically confirmed rhino-sino-orbital or cerebral mucormycosis after COVID-19 treatment during the second wave of COVID-19 in Pune, India. Median time to symptom onset from COVID-19 detection was 28 days. Moderate or severe COVID-19 was seen in 73% of patients and diabetes in 74.2%. A total of 52.8% received steroids. Eschar over or inside the nose was seen in 75%, but baseline clinical and laboratory parameters were mostly unremarkable. Bone penetration was present in ≈90% of cases, 30% had soft-tissue swelling of the pterygopalatine fossa and 7% had cavernous sinus thrombosis, and 60% had multifocal mucormycosis. Of the 178 study cases, 151 (85%) underwent surgical debridement. Twenty-six (15%) died, and 16 (62%) of those had multifocal mucormycosis.
