RESUMEN
Since the onset of COVID-19 pandemic, parallel opportunistic infections have also been emerging as another disease spectrum. Among all these opportunistic infection, mucormycosis has become a matter of concern with its rapid increase of cases with rapid spread as compared to pre-COVID-19 era. Cases have been reported in post-COVID-19-related immune suppression along with the presence of comorbidity which adds on the deadly outcome. There is no systematic review addressing the issue of COVID-19-associated mucormycosis. This is the first systematic review of published studies of mucormycosis associated with COVID-19. The aim was to analyze the real scenario of the disease statement including all the published studies from first November 2019 to 30th June to analyze the contemporary epidemiology, clinical manifestations, risk factor, prognosis, and treatment outcome of COVID-19 associated rhino-orbito-cerebral-mucormycosis. A comprehensive literature search was done in following databases, namely, PubMed, Google Scholar, Scopus, and EMBASE using keywords mucormycosis, rhino orbital cerebral mucormycosis, COVID-19, and SARS-CoV-2 (from November 01, 2019 to June 30, 2021). Our study shows that, while corticosteroids have proved to be lifesaving in severe to critical COVID-19 patients, its indiscriminate use has come with its price of rhino-orbito-cerebral mucormycosis epidemic, especially in India especially in patients with preexisting diabetes mellitus with higher mortality. Corticosteroid use should be monitored and all COVID-19 patients should be closely evaluated/monitored for sequelae of immunosuppression following treatment.

The purpose of this study was to describe the clinical presentation, imaging findings, and outcome in 10 dogs diagnosed with Rhinosporidium seeberi infections. Histopathology and cytology records were searched at a veterinary teaching hospital and a veterinary diagnostic laboratory to identify dogs with rhinosporidiosis. Medical records were reviewed for clinical, imaging, endoscopic, and surgical findings. Outcome was determined via evaluation of records and, where possible, telephone conversation with the primary care veterinarian and/or owner. Young to middle-aged large-breed dogs with an approximately equal sex distribution were represented. Unilateral signs predominated. Diagnosis was confirmed by histopathology in 9 cases, and cytology was diagnostic in only 1 of 3 cases. Histopathology was superior to cytology. Masses were soft tissue and contrast enhancing with no evidence of bony lysis on computed tomography (2 dogs). Direct or rhinoscopic (2 dogs) visualization revealed white to yellow pinpoint foci. Surgical resection (4 dogs) can result in long-term disease-free periods (up to 2659 days), although repeat surgery can be required. Dapsone was well tolerated in 1 dog, and relapse was not noted despite incomplete surgical resection (follow-up 749 days). Visualization of pale foci on a rostral intranasal mass in an endemic region should prompt consideration of rhinosporidiosis.

Mucormycosis is a progressive, opportunistic fungal infection with a high risk of mortality. Also mucormycosis may attack any organ system and may be accompanied by hemodynamic instability and difficult airway management. This study aimed to evaluate the anesthetic management of patients undergoing surgical resection for rhino-orbito-cerebral mucormycosis (ROC). The study evaluated 12 patients that underwent surgical resection for ROC mucormycosis under general anesthesia. Demographic characteristics, hemodynamic parameters, invasive monitoring methods, surgical procedures, hospital records, and mortality rates were reviewed for each patient. The patients had a median age of 58 (range, 5-86) years. Two patients had an American Society of Anesthesiologists (ASA) score of II while the remaining 10 patients had a score of III. Eleven (91.7%) patients had a diagnosis of rhino-orbital mucormycosis and 1 (8.3%) patient was diagnosed with ROC mucormycosis. Most common comorbidity was DM (n=8), followed by hematological malignancy (n=4), solid organ malignancy (n=3), and kidney transplantation (n=2). Invasive arterial monitoring was performed in 7 and central venous cannulation was performed in 5 patients. Six patients were transferred to the intensive care unit (ICU) and the mortality rate was 25% with an average mortality time was 7 days in 3 cases. In cases of ROC mucormycosis, necessary precautions should be taken for the difficult airway caused by fungal debris in the oropharyngeal region and supraglottic edema. Postoperative ICU is important due to comorbidities and fungal infection with high mortality.

BACKGROUND: Rhino-orbital-cerebral mucormycosis (ROCM) is an uncommon yet potentially lethal fungal infection. Although most cases originate from developing countries, an ageing population and increased prevalence of chronic illness may mean some clinicians practicing in developed countries will encounter ROCM cases in their careers. Yohai et al published a systematic review of 145 case reports from 1970 to 1993 assessing prognostic factors for patients presenting with ROCM. We present an updated review of the literature and assess whether survival outcomes have changed in the two decades since that seminal paper. SEARCH STRATEGY: An extensive Medline literature search was performed for case reports published between 1994 and 2015. RESULTS: In total, 210 published cases were identified from the literature review, of which 175 patients from 140 papers were included in this review. Fifty-five were female, with an overall mean age of 43 years. Overall survival rate was 59.5%, which was not significantly better than the previous series reported (60%) reported by Yohai et al. Survival rates in patients with chronic renal disease had improved, from 19% to 52%, and in patients with leukaemia (from 13% to 50%). Facial necrosis and hemiplegia remained poor prognostic indicators (33% and 39% survival rates, respectively). Early commencement of medical treatment related to better survival outcomes (61% if commenced within first 12 days of presentation, compared to 33% if after 13 days). Timing of surgery had less of an effect on overall survival. However, in 28 cases that did not receive any surgical treatment, survival was only 21%. CONCLUSIONS: Although overall survival rates have not improved, survival in patients with renal disease were better, potentially due to the introduction of liposomal amphotericin B which is less nephrotoxic. Prompt recognition of ROCM, reversal of predisposing co-morbidities and aggressive medical treatment remain the cornerstone of managing this highly aggressive disease.

Within a 10-y period, fatal strokes occurred during parenteral administration of amphotericin B and surgical debridement of paranasal sinuses in 6 pathologically verified cases of rhino-orbito-cerebral mucormycosis (ROCM). All patients had unnoticed type-2 diabetes mellitus without ketoacidosis. They presented with unilateral orbital cellulitis and cavernous sinus syndrome. Fatal malignant cerebral infarctions occurred in the carotid system in 5 patients, and in the basilar artery or its major branches in 2 patients. Accelerated thrombotic occlusion of the cavernous portion of the carotid artery or the basilar artery was likely to be due to mucormycosis associated-vasculopathy and diabetic vasculopathy. One patient died of massive subarachnoid hemorrhage following rupture of the mycotic aneurysm. Despite parenteral administration of amphotericin B, fatal outcome of ROCM in patients with unnoticed diabetes mellitus occurs due to mucormycosis-associated malignant strokes. To improve outcome, a combination of early radical debridement, ocular exenteration, parenteral and local administration of amphotericin B, and decompression craniotomy should be considered.

BACKGROUND: Rhino-orbito-cerebral mucormycosis (ROCM) is a devastating infection of immunocompromised hosts. We present our experience with 19 ROCM cases and attempt to define preferred diagnostic and treatment protocols. METHODS: All had tissue biopsies obtained studied by direct smear, histologic studies, and cultures. Imaging was obtained in 14 cases. RESULTS: Sixteen patients presented between August and November. Six had mixed fungal infections. Seven patients had end-stage underlying disease or infection and did not undergo surgery and 4 had an indolent form of disease. Patients were treated by surgery and by amphotericin B. The overall survival was 47%. CONCLUSIONS: ROCM may have seasonal incidence peaking in the fall and early winter. The therapeutic approach should be unchanged in cases of mixed fungal infections. Amphotericin B with aggressive debridement remains the mainstay of treatment. Early recognition and treatment are essential. A presentation and survival-dependent classification of ROCM are offered.

Mucormycosis is a highly aggressive fungal infection affecting diabetic, immunocompromised, and, occasionally, healthy patients. This infection is associated with significant mortality. We have reviewed 208 cases in the literature since 1970, 139 of which were presented in sufficient detail to assess prognostic factors, and added data from six of our patients. The histories of these 145 patients were analyzed for the following variables: 1) underlying conditions associated with mucormycotic infections; 2) incidence of ocular and orbital signs and symptoms; 3) incidence of nonocular signs and symptoms; 4) interval from symptom onset to treatment; and 5) the pattern of sinus involvement seen on imaging studies and noted at the time of surgery. Factors related to a lower survival rate include: 1) delayed diagnosis and treatment; 2) hemiparesis or hemiplegia; 3) bilateral sinus involvement; 4) leukemia; 5) renal disease; and 6) treatment with deferoxamine. The association of facial necrosis with a poor prognosis fell just short of statistical significance, but appears clinically important. This is the first review that documents the heretofore intuitive claim that early diagnosis is necessary to cure this disease. Standard treatment with amphotericin B and aggressive surgery are reviewed and adjunctive therapeutic modalities are discussed, including local amphotericin B irrigation, hyperbaric oxygen, and optimizing the immunosuppressive regimen in transplant patients. Hyperbaric oxygen was found to have a favorable effect on prognosis. In addition, possible treatment options for patients with declining renal function are reviewed.
