Battling the emerging epidemic of rhino-orbital-cerebral mucormycosis (ROCM) in COVID-19 pandemic: an interventional study.

PURPOSE: The most recent challenge being faced by the healthcare system during the worldwide COVID-19 pandemic is increase in the incidence rate of coinfection or superinfection; one of the most fatal being mucormycosis. This study aimed to estimate the risk factors, symptoms and signs, treatment outcome and prognosis of COVID-19-associated mucormycosis (CAM) patients. METHODS: This is an interventional study of 35 patients diagnosed and managed as CAM at a tertiary care centre in New Delhi, India. RESULTS: The mean age of patients was 40.45 ± 6 years with a male preponderance. CAM did not affect healthy individuals; the major risk factors included diabetes in 65.7% and injudicious steroid use in 51.4% patients. Orbital/facial edema was the most common presenting symptom (25.7%) as well as sign (28.57%). 68.5% patients were stage 3 (involvement of orbit) at presentation; 33.3% showed medial wall involvement. Treatment included intravenous Amphotericin and oral Posaconazole in all patients, paranasal sinus (PNS) debridement in 94.2%, orbital exenteration was done in 8 patients. Adjuvant retrobulbar Amphotericin B injection was administered in 12 patients with radiological resolution seen in 50% after 1 cycle. In patients with Stage 4 disease who underwent exenteration along with PNS debridement, survival rate was 100% at 30 days, and disease reduction occurred in 87.5% patients (P < 0.01). Overall, 68.5% responded to therapy, 8.5% showed progression and mortality rate was 22.85%, at a mean follow up period of 59.5 days. CONCLUSION: A multidisciplinary and aggressive approach is essential in the management of CAM patients.

Rhino-orbital mucormycosis in a patient with no susceptibility following P.vivax malaria infection-a case report.

BACKGROUND: Mucormycosis is a potentially lethal, angioinvasive fungal infection caused by the Mucoracea family comprising Mucor, Rhizopus, and Absidia species. It is commonly associated with uncontrolled diabetes mellitus, the use of corticosteroids, immunosuppressive drugs, and Covid-19 infection. The occurrence of mucormycosis in an immunocompetent patient is rare. Also, only a few case reports have been published where patients developed mucormycosis with associated malarial infection. CASE PRESENTATION: A young female presented with a 3-weeks history of painful swelling and outward protrusion of the right eye with complete loss of vision. She had a history of P.vivax malaria two weeks before her ocular symptoms. On ocular examination, there was proptosis and total ophthalmoplegia with loss of corneal sensations in the right eye. Hematological examination revealed normocytic normochromic anemia and thrombocytopenia. MRI was suggestive of right-sided pansinusitis and orbital cellulitis with right superior ophthalmic vein thrombosis and bulky cavernous sinus. Nasal biopsy was negative for fungal culture. An emergency surgical debridement of all the sinuses was done with right orbital exenteration. Histopathology confirmed the diagnosis of mucormycosis and the patient improved post-operatively on systemic antifungals. CONCLUSION: Such an association of mucormycosis with malaria infection is rarely reported in the literature and is hypothesized to be a result of immunosuppression caused by malaria. Also, emphasis is laid upon having a high index of suspicion for fungal infection in the setting of pansinusitis even if the risk factors are absent. We hereby report a case of rhino-orbital mucormycosis following P.vivax malaria in a 20-year-old female with anemia and thrombocytopenia.

Crisis Standards of Care-More Than Just a Thought Experiment?

As described in two articles in the September-October 2021 issue of the Hastings Center Report, most crisis standards of care (CSC) plans include triage algorithms to guide the allocation of critical care resources to some patients and not others under conditions of extreme scarcity. The plans also include other important CSC strategies, but it is the notion of rationing scarce resources via triage that especially captured the imaginations of ethicists. Vigorous arguments have arisen over whether triage algorithms should be designed to prioritize patients based on predictions of short-, near-, or long-term survival. Additionally, there are ongoing debates about the ability of current algorithms to estimate patient survival accurately enough to be useful in triage and about the role of values like equity in triage protocols. Relatively few debates have noted, however, that while the development of CSC triage protocols has been based in medicine, public health, and ethics, the activation of CSC plans remains a political decision.

Safety and Outcomes of Prolonged Usual Care Prone Position Mechanical Ventilation to Treat Acute Coronavirus Disease 2019 Hypoxemic Respiratory Failure.

OBJECTIVES: Prone position ventilation is a potentially life-saving ancillary intervention but is not widely adopted for coronavirus disease 2019 or acute respiratory distress syndrome from other causes. Implementation of lung-protective ventilation including prone positioning for coronavirus disease 2019 acute respiratory distress syndrome is limited by isolation precautions and personal protective equipment scarcity. We sought to determine the safety and associated clinical outcomes for coronavirus disease 2019 acute respiratory distress syndrome treated with prolonged prone position ventilation without daily repositioning. DESIGN: Retrospective single-center study. SETTING: Community academic medical ICU. PATIENTS: Sequential mechanically ventilated patients with coronavirus disease 2019 acute respiratory distress syndrome. INTERVENTIONS: Lung-protective ventilation and prolonged protocolized prone position ventilation without daily supine repositioning. Supine repositioning was performed only when Fio2 less than 60% with positive end-expiratory pressure less than 10 cm H2O for greater than or equal to 4 hours. MEASUREMENTS AND MAIN RESULTS: Primary safety outcome: proportion with pressure wounds by Grades (0-4). Secondary outcomes: hospital survival, length of stay, rates of facial and limb edema, hospital-acquired infections, device displacement, and measures of lung mechanics and oxygenation. Eighty-seven coronavirus disease 2019 patients were mechanically ventilated. Sixty-one were treated with prone position ventilation, whereas 26 did not meet criteria. Forty-two survived (68.9%). Median (interquartile range) time from intubation to prone position ventilation was 0.28 d (0.11-0.80 d). Total prone position ventilation duration was 4.87 d (2.08-9.97 d). Prone position ventilation was applied for 30.3% (18.2-42.2%) of the first 28 days. Pao2:Fio2 diverged significantly by day 3 between survivors 147 (108-164) and nonsurvivors 107 (85-146), mean difference -9.632 (95% CI, -48.3 to 0.0; p = 0·05). Age, driving pressure, day 1, and day 3 Pao2:Fio2 were predictive of time to death. Thirty-eight (71.7%) developed ventral pressure wounds that were associated with prone position ventilation duration and day 3 Sequential Organ Failure Assessment. Limb weakness occurred in 58 (95.1%) with brachial plexus palsies in five (8.2%). Hospital-acquired infections other than central line-associated blood stream infections were infrequent. CONCLUSIONS: Prolonged prone position ventilation was feasible and relatively safe with implications for wider adoption in treating critically ill coronavirus disease 2019 patients and acute respiratory distress syndrome of other etiologies.
