ABSTRACT
Objective: With coronavirus disease 2019 (COVID-19) pandemic across the world, there had been an exponential increase in rhino-orbito-cerebral mucormycosis (ROCM). Extension of infection to cavernous sinus leads to cavernous sinus syndrome (CSS). This study aims to describe incidence, clinicoradiological profile, and outcome of CSS positive along with comparative analysis of CSS negative COVID-19-associated ROCM. Material and Method: This was a prospective and observational study conducted from May 1, 2021, to July 31, 2021. Subjects included ROCM with active or recovered COVID-19 (past 6 weeks) and were categorized and staged. CSS was defined as involvement of two or more of third, fourth, fifth, or sixth cranial nerve with one each direct and indirect qualitative neuroradiological features. Clinicoradiological features of CSS-positive and negative COVID-19-associated ROCM groups were compared. Results: Incidence of CSS with COVID-19-associated ROCM was 28%. Mean age of subjects was 44 ± 15 years with 60% being males and 73% were proven ROCM. Significant differences seen across the CSS-positive and negative groups were ocular, nasal, and cerebral findings including eyelid and periocular discoloration, ptosis, proptosis, ophthalmoplegia, nasal discharge, mucosal inflammation, and fever. Oculomotor, trochlear, and abducens nerves were significantly involved more in CSS-positive group. Significant radiological findings across two groups included indirect features in orbit, nose, and paranasal sinuses along with direct features in cavernous sinus. Surgical intervention was more common in CSS-positive group. Mortality in CSS-positive group at 8–24 weeks was 13 and 27%, respectively. Conclusion: Extension of ROCM to CSS was more common in young males in advanced stages of proven ROCM with concurrent COVID-19. CSS-positive group had significant difference in clinicoradiological features involving orbit, nose, paranasal sinuses, and central nervous system as compared to CSS-negative group. This study highlights the need to develop an objective scoring system considering clinical and radiological features for diagnosis of CSS with COVID-19-associated ROCM.
ABSTRACT
Context: Coronavirus infectious disease (COVID-19) pandemic disrupted the already marginalized healthcare provision in resource limited countries like India. Aims: This study compared onset to door time and temporal trends of admissions to seek medical care in new onset acute ischaemic stroke during the COVID-19 period with a representative pre-COVID-19 period in rural background. Settings and Design: Prospective Cross-sectional study in a tertiary level hospital in North India. Methods and Material: Study included new onset acute ischaemic stroke admitted within first 2 weeks of symptoms onset. Subjects were divided into: Group A – Pre-COVID-19 stroke, Group B – Non-COVID-19 Stroke, and Group C - Stroke, positive for COVID-19. Detailed epidemiological, clinical profile, onset to door time and temporal trends of admissions were recorded. Statistical Analysis Used: Chi square/Fisher’s exact test and Independent Samples T test or Mann–Whitney U test were used for categorical and continuous variables. Results: Onset to door time in new onset acute ischaemic stroke was significantly prolonged by 6 h in COVID-19 period (median (interquartile range), 19 (12–27) h) as compared with pre-COVID-19 period. Admissions of new onset acute ischaemic stroke were significantly less in COVID-19 period. Comorbidities and severity of stroke (mean National Institutes of Health Stroke Scale, 20 ± 4) were more during the COVID-19 period. Incidence and mortality of COVID-19 positive new onset acute ischaemic stroke were 0.95% and 38%. Conclusions: Onset to door time in new onset acute ischaemic stroke was significantly prolonged in COVID-19 as compared with pre-COVID-19 period. The admissions were fewer with more severity and comorbidities in COVID-19 period. COVID-19 positive stroke patients had more severity and mortality as compared with non-COVID-19 stroke.
