Osteomielite maxilar associada ao COVID-19: mucormicose ou não? Uma série de casos / Maxillary osteomyelitis associated with COVID-19: mucormycosis or not? A series of cases

Aim: A series of cases have been presented involving the oral cavity focusing on the presentation, diagnosis and treatment of mucormycosis that can form a basis for successful therapy. Background: The management of severe coronavirus disease (COVID-19) in conjunction with comorbidities such as diabetes mellitus, hematological malignancies, organ transplants, and immunosuppression have led to a rise of mucormycosis which is an opportunistic infection. Cases Description: The various forms that have been enlisted till date are rhino-cerebral, rhino-orbital, gastrointestinal, cutaneous, and disseminated mucormycosis. From the dentistry and maxillofacial surgery perspective, the cases depicting extension of mucormycosis into the oral cavity have been less frequently recorded and thus, require a detailed study. The patients that reported to our private practice had non-tender swelling, draining sinuses and mobility of teeth. A similarity was observed in the clinical signs both in osteomyelitis and mucormycosis. Thus, a histopathological examination was used to establish the definitive diagnosis. Conclusion: Mucormycosis is a life threatening pathology that requires intervention by other branches to make an early diagnosis and commence the treatment. The characteristic ulceration or necrosis is often absent in the initial stage and thus, histopathological examination and radiographic assessment are required to formulate a definitive diagnosis. Early intervention is a necessity to avoid morbidity. The treatment involves surgical debridement of the necrotic infected tissue followed by systemic antifungal therapy. Mucormycosis has recently seen a spike in its prevalence, post the second-wave of coronavirus pandemic in India. It was seen commonly in patients with compromised immunity, diabetes mellitus, hematological malignancies, or on corticosteroid therapy. Mucormycosis invading the palate mostly via maxillary sinus has been less frequently described. In the post-COVID era the features associated with mucormycosis involving oral cavity, should warrant a possible differential diagnosis and managed appropriately. (AU)

Objetivo: Apresentar uma série de casos com enfâse na apresentação, diagnóstico e tratamento da mucormicose oral, assim como uma revisão sistemática que sirva como base para estabelecimento de terapias de sucesso. Introdução: A forma severa da infecção por coronavirus (COVID-19) associada a diabetes mellitus, doenças hematológicas malignas, transplante de órgãos e imunossupressão levaram a um aumento das infecções oportunistas de mucormicose. Descrição dos Casos: As diversas apresentações clínicas que foram descritas até o momento são a rinocerebral, rino-orbital, gastrointestinal, cutânea e mucormicose disseminada. No que concerne a odontologia e a cirurgia maxillofacial, os casos que apresentam extensão de mucormicose para cavidade oral tem sido menos reportados e assim requerem mais estudos. Os pacientes que compareceram a nossa clínica apresentavam aumento de volume endurecido, drenagem de fluidos dos seios maxilares e mobilidade dentária. Clinicamente tanto a osteomielite quanto a mucormicose apresentaram-se de forma semelhante. Assim, análise histopatológica foi utilizada para estabelecimento do diagnóstico definitivo. Conclusão: A mucormicose é uma patologia grave que requer intervenção precoce para estabelecimento do tratamento. A ulceração e necrose características usualmente estão ausentes nos estágios iniciais da lesão, assim análise histopatológica e radiográfica são necessárias para o diagnóstico final. Intervenção precoce é necessária para diminuir a morbidade. O tratamento envolve o debridamento cirúrgico da área necrosada seguida de terapia antifúngica sistêmica. Recentemente, houve um aumento nos casos de mucormicose, após a Segunda onda da pandemia de COVID-19 na índia. Os casos acometiam principalmente pacientes imunocomprometidos, com diabetes mellitus, doenças hematológicas malignas e em uso de corticosteróides. A mucormicose invadindo o palato pelos seios maxilares foi raramente descrita. Na era pós-COVID a mucormicose envolvendo a cavidade oral deve entrar no painel de diagnósticos diferenciais para que o tratamento adequado possa ser instituído precocemente.(AU)

Bone Anatomy of the Thoracic Limb in the Common Hippopotamus (Hippopotamus amphibius) and White Rhinoceros (Ceratotherium simum)

SUMMARY: Although megaherbivores do not belong to the Brazilian fauna, they can be found in national zoos, which makes it important to know the anatomy of the locomotor apparatus to contribute to the clinical routine of zoos and veterinary rehabilitation centers. Thus, the aim of this study was to describe the anatomical structures of the thoracic limb bones in the common hippopotamus (Hippopotamus amphibius) and white rhinoceros (Ceratotherium simum) and to compare them with the bone structures described for other ungulates. The scapula had a triangular appearance in the common hippopotamus, whereas in the white rhinoceros it had a rectangular appearance. The acromion was observed only in the common hippopotamus scapula. The hippopotamus humerus did not have the intermediate tubercle, only the greater and lesser tubercles, unlike the rhinoceros which also has the intermediate tubercle. The two megamammals studied had an ulna not incorporated to the radius and seven carpal bones distributed in two bone rows. The common hippopotamus had four digits and four metacarpal bones, while the white rhino had three digits, hence three metacarpal bones. Although with some species-specific differences, the bone anatomy found in the studied megaherbivores was similar to that described for domestic ungulates, such as horses and cattle. The fact that the bones studied belong to articulated skeletons of the collection of the Museum of Anatomy made it difficult to identify some anatomical structures. This study can help veterinarians in bone health care, animal welfare and comfort of such species present in Brazilian zoological parks.

Aunque los megaherbívoros no pertenecen a la fauna brasileña, se pueden encontrar en zoológicos nacionales, lo que hace importante conocer la anatomía del aparato locomotor para contribuir a la rutina clínica de los zoológicos y de los centros de rehabilitación veterinaria. Por tanto, el objetivo de este estudio fue describir las estructuras anatómicas de los huesos de los miembros torácicos en el hipopótamo común (Hippopotamus amphibius) y el rinoceronte blanco (Ceratotherium simum) y compararlas con las estructuras óseas descritas para otros ungulados. La escápula tenía una apariencia triangular en el hipopótamo común, mientras que en el rinoceronte blanco tenía una apariencia rectangular. El acromion se observó sólo en la escápula del hipopótamo común. El húmero del hipopótamo no tenía el tubérculo intermedio, sólo los tubérculos mayor y menor, a diferencia del rinoceronte que también tiene el tubérculo intermedio. Los dos ejemplares de megamamíferos estudiados tenían una ulna no incorporada al radio y siete huesos del carpo distribuidos en dos filas óseas. En el hipopótamo común se observaron cuatro dedos y cuatro huesos metacarpianos, mientras que en el rinoceronte blanco se encontraron tres dedos, por lo tanto, tres huesos metacarpianos.A pesar de algunas diferencias específicas de cada especie, la anatomía ósea encontrada en los megaherbívoros estudiados fue similar a la descrita para los ungulados domésticos, tal como los caballos y el ganado. El hecho de que los huesos estudiados pertenezcan a esqueletos articulados de la colección del Museo de Anatomía dificultó la identificación de algunas estructuras anatómicas. Este estudio puede ayudar a los veterinarios en el cuidado de la salud ósea, el bienestar animal y el confort de las especies presentes en los parques zoológicos brasileños.

Comparative evaluation of histopathological analysis, KOH wet mount and fungal culture to diagnose fungal infections in post-COVID patients

Context and Aim: There is increasing prevalence of post-COVID fungal infection of rhinoorbitocerebral region especially mucormycosis and aspergillosis in India.[1] Early diagnosis of these fungal infections are of utmost importance, since it may improve outcome and survival.[2],[3],[4],[5],[6],[7],[8] The objective of this study was to evaluate and compare routine laboratory diagnostic methods, that is, histopathological examination, KOH wet mount and fungal culture in the diagnosis of post-COVID fungal infections. Materials and Methods: A total of 106 specimens of clinically suspected patients of post-COVID fungal infection of rhinoorbitocerebral region received in histopathology department were included in this study. The data of KOH wet mount and culture were acquired from the microbiology department after histopathological examination. Result: Approximately 88.68% of patients were diagnosed having fungal infections by one of the laboratory methods. The sensitivity of histopathological examination was highest (79.78%), followed by KOH wet mount (58.51%) and fungal culture (35.10%). Rhizopus species of zygomycetes group were the most common isolate (24.24%) on SDA culture. Overall 76% concordance was found between histopathological examination and fungal culture report for morphological identification of fungi. Conclusion: For the diagnosis of post-COVID fungal infection of Rhino-orbito-cerebral region, histopathological examination is was found to be more sensitive and rapid method to detect fungal hyphae. It leads to early treatment, prevents morbidity and mortality.

Case series of central retinal artery occlusion in COVID-19-associated rhino-orbital-cerebral mucormycosis

Rhino orbital Mucormycosis caused by filamentous fungus of mucoraceae family was considered a rare disease affecting immunocompromised and diabetics with ketoacidosis until the recent COVID 19 pandemic. We are presenting a series of six cases of Rhino orbital cerebral Mucormycosis with central retinal artery occlusion. All six cases had common history of COVID 19 infection in recent past with sinusitis, proptosis and total ophthalmoplegia with central retinal artery occlusion on presentation. MR imaging showed invasive pan sinusitis with orbital and cerebral involvement. Urgent debridement was done and histopathological examination showed broad, filamentous aseptate fungi suggestive of Mucormycosis. All patients inspite of intravenous Amphotericin B with local debridement did not show any improvement and expired within a week of presentation. Hence our study shows poor prognosis of post covid 19 associated Mucormycosis with central retinal artery occlusion.

A retrospective clinicopathological analysis of rhino-orbital mucormycosis in second wave of COVID-19

Background: During the present surge of COVID-19 positive cases, concurrent multifold increase in the incidence of mucormycosis cases has resulted into significant morbidity and mortality. We retrospectively evaluated the clinicopathological features along with microbiological examination findings in histologically diagnosed cases of rhino-orbital mucormycosis. Material and Methods: All the H and E and special stained slides of included mucormycosis cases were retrieved from the records and were evaluated with microbiological findings including screening KOH mount examination and culture results. Results: Out of 16 cases with available details, 10 cases had the previous history of diabetes mellitus. The most frequent single site of involvement was maxillary sinus (7/25) followed by nasal cavity, orbit, ethmoid and sphenoid sinuses. While comparing the histological diagnosis with KOH mount findings and culture results, 15 cases revealed consistent results. Conclusion: A high clinical suspicion, monitoring, early diagnosis, and timely management can improve the morbidity and mortality of this life-threatening complication.

A hospital-based study on COVID-19 patients with rhino-orbital mucormycosis

Coronavirus diseases 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 virus produce opportunistic fungal infections. Mucormycosis is an acute onset rapidly progressive fatal infection. Incidence of rhino-orbital mucormycosis raised during the second wave of COVID-19 pandemic in India. Diabetes, steroid therapy, cancer, prolonged hospitalization, and metabolic acidosis are the risk factors of post-COVID-19 mucormycosis. Objectives of this study were to suggest the risk factors, clinical features, investigations, and treatment of post-COVID-19 rhino-orbital mucormycosis. This study will guide the future research and the clinician will be aware about this complication of COVID-19. After getting permission from the Institutional Ethical Committee and consent from patients, we studied 10 cases of post-COVID-19 rhino-orbital mucormycosis from April to September 2021 during our duty in COVID-19 admission desk and COVID-19 ward in NRS Medical College, Kolkata. After taking history, we observed the clinical features, investigations, and treatment of the patients. Symptoms of the patients were nasal discharge, nasal block, headache, facial swelling, and blackish discoloration of skin. Most of the patients were diabetic. Magnetic resonance imaging (MRI)-PNS was showed sinonasal mass. Amphotericin-B was used and debridement was the main surgical procedure. Microscopy showed broad aseptate hyphae suggesting mucor. Early diagnosis and proper treatment will reduce the morbidity and mortality of the patient with post-COVID rhino-orbital mucormycosis.

Histomorphological-study-of-mucormycosis-in-covid19-patients-with-special-reference-to-rhinoorbital-region-in-a-tertiary-care-center

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in December 2019 in Wuhan city, Hubei province, China. The patients with comorbid conditions like diabetes mellitus, lung disease are prone to a wide range of viral, bacterial and fungal infections. Aims And Objectives 1. To know the frequency of mucormycosis in Covid-19 patients. 2. To describe histomorphological pattern of mucormycosis and other fungal infections in Covid-19 patients. Materials And Methods: A prospective study was conducted from May 2021 to August 2021 for four month period with a sample size of 57 at a tertiary care hospital in south India. All the patients who were diagnosed with and or recovered from COVID-19 infection and came back with the fungal infection symptoms were subjected to surgical debridement were included in the study. All the demographic and clinical data were obtained from requests. In the presentResults: study we got 57 cases of covid-19 patient with suspected fungal infections.We examined the biopsy taken from different sites of rhinoorbital area with H&E and GMS stain. Out of 57 cases 36 cases were found to be having mucormycosis. Conclusion: Since Covid-19 is a risk for many opportunistic infections, its association with invasive fungal infection is dangerous and must be given serious consideration

Corneal manifestations and treatment among patients with COVID-19-associated rhino-orbito-cerebral mucormycosis

Purpose: TO report the corneal manifestations in patients with COVID?19?associated rhino?orbito?cerebral mucormycosis (ROCM). Methods: This study was a retrospective, observational, and record?based analysis of patients of ROCM with corneal involvement. Results: A total of 220 patients were diagnosed with ROCM over a period of 3 months. Thirty?two patients had developed corneal manifestations. The mean age at diagnosis was 52.84 ± 12.8 years. The associated risk factors were systemic mucormycosis, uncontrolled diabetes, recent COVID?19 infection, and injudicious use of systemic steroids. Twenty?nine patients were known diabetics, 32 had recent COVID?19 infection, and 13 gave a history of injudicious use of steroids. The right eye (RE) was affected in nine patients, the left eye (LE) in 20 patients, and both eyes in three patients. Nine patients had a round?oval corneal ulcer. One patient each had a perforated corneal ulcer with uveal prolapse, sealed perforated corneal ulcer, spontaneously healed limbal perforation, diffuse corneal haze with hyphemia, panophthalmitis, diffuse corneal stromal abscess, limbal ischemia, anterior uveitis with posterior synechiae, inferior corneal facet, and filamentary keratitis. Three patients each had a corneal melt and inferior conjunctival xerosis with chemosis. Orbital exenteration was performed in six patients. Five patients with corneal ulcers healed. Topical eye drops of amphotericin (0.5 mg/ ml) cycloplegic, antiglaucoma medications, and lubricant eye drops were started along with systemic antifungals. Conclusion: Central corneal ulcer was the most common manifestation of mucormycosis. A concentration as low as 0.5 mg/ml of amphotericin eye drops was effective in the treatment.

A cross-sectional study to describe the spectrum of ocular manifestations and risk factors of mucormycosis presenting to a tertiary hospital of East India

Purpose: To report the clinico?demographic profile of rhino?orbito?cerebral mucormycosis (ROCM) in patients during the “second wave” of the COVID?19 pandemic in eastern India, and their ophthalmic manifestations at presentation to our tertiary institute. Methods: Cross?sectional study amongst patients presenting to our center based on their hospital records. Demographic information, history related to COVID?19, records of detailed ocular examination, and microbiological, radiological, and histopathological investigation were entered into an online worksheet and analyzed using SPSS 26.0. Results: A total of 219 patients with ROCM were treated from May to September 2021, and 110 of these had ocular manifestations at presentation (50.2%). The age of patients ranged from 22 to 83 years and the mean ± standard deviation (SD) age was 49.9 ± 12.9 years. Ninety (81.8%) patients had been diagnosed with diabetes mellitus, 31 (34%) had hypertension, and 10 had other comorbidities. The duration between the onset of COVID?19 and mucormycosis symptoms was 0 to 60 days with a mean ± SD interval of 20.9 ± 12.6 days. Fifty?six (50.9%) patients had a history of steroid use. Unrelenting ocular or facial pain was the most common presenting symptom, ptosis was the most common anterior segment manifestation, and ophthalmic artery occlusion was the most common posterior segment manifestation. Conclusion: Our data from eastern India reinforces the relationship between COVID?19, diabetes, corticosteroid use, and ROCM. Knowledge of various presenting anterior and posterior segment manifestations of the disease as described in the present study will guide clinicians to recognize the disease early and make every effort to prevent complications.

Central retinal vein occlusion as primary ocular manifestation of rhino-orbital-cerebral mucormycosis: A case report

Mucormycosis is a serious, rapidly progressing, life-threatening, and sight threatening fungal infection frequently seen in diabetics and immunocompromised patients. We report a rare occurrence of rhino-orbital mucormycosis presenting as unilateral central retinal vein occlusion (CRVO) and no other ocular signs of infection in a 65-year-old diabetic male. The definitive diagnosis was made by nasal biopsy which confirmed broad branching aseptate fungal hyphae. The patient was treated with amphotericin B for mucormycosis and intravitreal anti-vascular growth factor (anti-VEGF) drug for macular edema. To conclude, although ophthalmoplegia is the most common ocular presentation and retinal artery occlusion is the most common cause of visual loss in mucormycosis, it may have many varied presentations including CRVO. A high index of suspicion must be kept in diabetics and immunocompromised patients

Risk Factors for Severe Rhino-Orbital Mucormycosis During its Epidemic Post-COVID-19 Pandemic

Postsecond wave of COVID?19 pandemic in the year 2021, rhino?orbital mucormycosis(ROM) was seen as an epidemic in the Indian community. Severe ROM disease has poor prognosis and requires a multidisciplinary approach for treatment. Hence, its prevention is better than cure. Studies done during the epidemic assessed predisposing factors, but this was a novel study which focused on assessing risk factors for severe disease of ROM. Ninety-four consecutive patients of ROM admitted at our designated nodal tertiary hospital of North India were enrolled, and data were collected and analyzed. Facial edema was the most common presenting complaint. Subclinical and mild COVID-19 infection was associated with severe ROM. Uncontrolled diabetes mellitus and prophylactic zinc supplementation were other significant risk factors for severe ROM. Public awareness among the general population for the above risk factors can prevent a debilitating disease like severe ROM.

Uncontrolled diabetes mellitus exacerbated by COVID-19–induced inflammation is the risk factor for COVID-19–associated rhino-orbito-cerebral mucormycosis: A matched pair case–control study

Purpose: Amidst the ongoing coronavirus disease 2019 (COVID-19) pandemic, India experienced an epidemic of COVID-19–associated rhino-orbito-cerebral mucormycosis (ROCM). This study aimed to describe the epidemiology and elucidate the risk factors for developing COVID-19–associated ROCM, comparing the risk factors among COVID-19 patients with and without ROCM. Methods: This case–control study included all COVID-19–associated ROCM patients treated at our hospital from May 1 to July 30, 2021. Controls included age- and sex-matched COVID-19 patients without ROCM, who were treated during the same time (exact matching, in 1:2 ratio). Matched pair analysis using conditional logistic regression was performed to examine the association of various risk factors with the development of ROCM in COVID-19 patients. Results: The study included 69 patients with COVID-19–associated ROCM and 138 age- and gender-matched controls. Epidemiologically, COVID-19–associated ROCM predominantly affected males (59/69, 85%), in their early 50s (mean 52 years), with 48% (33/69) of patients being from medical resource-constrained settings. On multivariate conditional logistic regression, elevated serum glycated hemoglobin (HbA1c) (odds ratio [OR] = 1.36, 95% confidence interval [CI]: 1.03–1.78), blood glucose (OR = 1.008, 95% CI: 1.003–1.013), and C-reactive protein (CRP) (OR = 1.07, 95% CI: 1.02–1.17) were associated with increased odds of developing COVID-19–associated ROCM. Patients with undetected diabetes mellitus with increasing HbA1c (OR = 3.42, 95% CI: 1.30–9.02) and blood glucose (OR = 1.02, 95% CI: 1.005–1.03) (P = 0.02) had a higher probability of developing COVID-19–associated ROCM than patients with established DM. Conclusion: Uncontrolled DM evidenced by elevated HbA1c and blood glucose levels, exacerbated by COVID-19–induced proinflammatory state indicated by elevated CRP, is the principal independent risk factor for COVID-19–associated ROCM. Middle-aged males with undetected DM, from a resource-constraint setting, are particularly at risk.

Analysis of COVID-19-associated rhino-orbital-cerebral mucormycosis patients in a tertiary care center in Northern India

Purpose: An unprecedented surge has been noted in rhino?orbital?Cerebral mucormycosis (ROCM) in times of current COVID?19 pandemic. The present prospective study aims to evaluate clinico?epidemiological profile, risk factors, management, and outcome of the cases of ROCM that presented to our tertiary care center during the study period from April to June 2021. Methods: All patients were subjected to complete history taking, ophthalmological examination, and imaging studies. The patients were staged and were treated with intravenous liposomal amphotericin B (AMB) and sino?nasal debridement of local necrotic tissue. Transcutaneous retrobulbar AMB (TRAMB), orbital decompression, and exenteration were instituted as indicated. All patients were followed up for a minimum of 6 months before arriving at the final outcome. Statistical analysis was performed. Results: A total of 49 patients presented during the study period, with a mean age of 42.2 years. The major risk factors included uncontrolled diabetes (89.8%), COVID?19 positivity (51.02%), and concurrent steroid use (38.77%). The most common presenting symptom was facial pain/swelling (43.65%), while the most common presenting sign was deterioration in vision (75.51%). Intravenous liposomal AMB was given to all patients along with sino?nasal debridement (85.71%), TRAMB (57.14%), orbital decompression (14.28%), and exenteration (12.24%). Overall, mortality at 6 months was 22.45% (11 patients). Age more than 60 years, intracranial extension, and HbA1c of more than 8.0% were observed to be statistically significant indicators of mortality. Conclusion: Early suspicion and timely diagnosis of mucormycosis at rhino?orbital stage is warranted in order to salvage life as well as visual function. TRAMB may prove as potentially favorable treatment modality in cases with limited orbital involvement.

To Determine The Role Of Imaging Findings On Computed Tomography (CT) And Magnetic Resonance Imaging (MRI) Predictive Of Acute Invasive Rhino-Orbito-Cerebral Mucormycosis (ROCM) In COVID 19 Patients

Background:There is a sudden rise of fungal infection with coronavirus disease. This is attributed to the immunomodulation by the disease and the drugs used, diabetes mellitus, steroid use, oxygen inhalation using dirty water, use of zinc and iron supplements, etc. Early diagnosis and prompt medical and surgical intervention is the mainstay of treatment. This can greatly reduce the high morbidity and mortality associated with this disease. The objective of the retrospective study is to describe the imaging findings of acute invasive rhino-orbito-cerebral mucormycosis (ROCM) in 58 patients with severe acute respiratory syndrome coronavirus 2, from SVP hospital with proven mucormycosis. Special emphasis is placed on the signal patterns of sinonasal mucosa, the earliest and most common findings.Material And Methods:We report the sinonasal, orbital and neuroimaging findings in patients of suspected acute invasive ROCM. A total of 58 patient’s scans were analyzed. The study comprises cases performed at two different imaging modalities and a tertiary care hospital from March 23,2021 to September 1, 2021. All the patients had positive reverse transcriptase polymerase chain reaction test for severe acute respiratory syndrome coronavirus 2 and were hospitalized with clinically severe disease as per the guideline s laid down during the second wave in India. They were on intravenous steroids and oxygen. Thirty patients (52%) had diabetes mellitus. All of them presented with headache, facialand/or orbital pain,periorbital puffiness with decreased vision, during the course of treatment. CT or MRI examination of the paranasal sinuses, orbits and brain was done, with intravenous contrast wherever possible. The presence of mucormycosis was confirmed by histological diagnosis in all of them following clinico-radiological diagnosis of acute invasive ROCM. Result:Computed tomography (CT) and magnetic resonance imaging (MRI) of 58 patients showed most commonly involved sinuse s as maxillary and ethmoid sinuses together. Sino-nasal mucosal thickening was the most common finding. Periantral infiltration preceded orbital, cerebral complications, with grossly intact bones. Sinus wall erosions were seen in only patients and maxillary alveolar arch erosionwere frequent findings. CT showed hypodense soft tissue thickening or fat stranding as the predominant finding in involved areas, while MRI showed T2 iso-to hyperintense mucosal thickening with T2 hypointense component as the main finding. Conclusion:MRI is better at demonstrating early mucosal abnormalities, turbinate necrosis, devitalized tissues, orbital apex involvement and intra-cerebral extension. Imaging findings of inflammatory tissue infiltration adjacent to the paranasal sinuses in premaxillary, retroantral fat, facial muscles, pterygopalatine fossa, temporal, infratemporal fossa and extraconal orbital-fat along with typical patterns of sinonasal mucosal thickening should raise the suspicion of acute invasive fungal etiology given the short duration of history and immunocompromised status. High incidence of periantral and orbital extension of the disease is suggestive of acute invasive form of fungal infection. Also the rapidly progressive inflammatory changes without much bone involvement should suggest the suspicion of ROCM. Bony, cerebral and vascular involvements are relatively late complications.

A Hospital based Observational Study of Clinical spectrum and Outcome of Mucormycosis during the COVID Pandemic

Background : Mucormycosis is a life threatening fungal disease caused by the filamentous fungi mucormycetes. Though a known entity for decades, it began to manifest in an unprecedented manner in the COVID scenario specially with the second wave in India. The objectives were to describe the demographic characteristics, clinical presentations, risk factors, therapy and in-hospital mortality of patients with Mucormycosis. Material and Methods : We conducted a retrospective observational study for a period of six months from March 2021 to August 2021. The data was collected for cases of mucormycosis from multiple centres all over West Bengal and analysed. All consecutive individuals with confirmed mucormycosis were enrolled in this study. The data documenting demographic particulars, presentation, predisposing factors and comorbiditieswere recorded in a pre validated case report form Details of investigation recording site and extent of disease, therapeutic intervention and outcome was mentioned . Statistical analysis was done using SPSS 21.0 for MS-Windows. Results : The total number of cases from March to August 2021 was 263 . There were 171 males and 92 females and the mean age of occurrence was 50.8±0.4 years .In West Bengal clusters of cases were being reported most commonly from the districts of North 24 Parganas, Kolkata, Jalpaiguri, Darjeeling and Hooghly. Some cases admitted here hailed from outside states like Bihar, Jharkhand, Odisha and Assam. The majority of the cases 74.22% (196)were COVID Associated Mucormycosis (CAM) while only 25.78% were non COVID associated. Diabetes mellitus was associated in 78.7 % and history of prolonged steroid therapy in 57.4% of cases. We encountered rhino orbital mucormycosis in 99.24 % of cases and cerebral involvement in 47.3%. They were treated with Amphotericin B deoxycholate along with endoscopic debridement. The most common side effects of Amphotericin B Deoxycholate were hypokalemia (93%), hypomagnesemia (32%) and AKI (74%) of the cases .The number of patients discharged was 16.7% and 10 left against medical advice (LAMA) . In hospital deaths were recorded to be 26.7%. Cause of death was commonly -AKI, septic shock and multiorgan failure . Conclusion : Prevention is better than cure of this devastating disease which is difficult todiagnose and treat .Awareness about mucormycosis and careful clinical evaluation of post-COVID patients is mandatory in this era in order to rapidly diagnose and treat mucormycosis

Bilateral blindness in a young male of rhino-orbital-cerebral mucormycosis: A case report

The storm of COVID?19?associated mucormycosis (CAM) has not yet settled, and it has proven itself a disfiguring and potentially life?threatening disease, complicating the course of COVID?19 infection. Mucormycosis is a rare but devastating fungal infection caused by filamentous fungi of the family Mucoraceae. We report a rare case of a 37?year?old diabetic male with bilateral rhino?orbital?cerebral mucormycosis (ROCM) where it leads to bilateral central retinal artery occlusion (CRAO) as manifestation of the disease. Bilateral CRAO secondary to ROCM is extremely rare. A strong suspicion of CAM in uncontrolled diabetics can result in early diagnosis and management.

Rhino-orbital-cerebral mucormycosis: An epidemiological study from a tertiary care referral center in Western India

Purpose: Rhino?orbital?cerebral mucormycosis (ROCM) is a rare opportunistic fungal infection with a fulminant course and an often fatal outcome. It can occur in immune?compromised patients such as those having uncontrolled diabetes, on long?term corticosteroid or immunosuppressive therapy, with COVID?19 infection, renal failure, AIDS, malignancy, or organ transplant. The aim of our study was to study the epidemiology of mucormycosis in COVID?19 patients and identify its risk factors. Methods: Ours was an epidemiological study wherein we gathered the demographic, clinical, histopathological, and radiological data of 458 patients of mucormycosis who presented to us between August 2020 and May 2021. Mucormycosis was defined through clinical and radiological findings or positive culture reports. Results: Out of all, 20.74% of patients did not have any past or concurrent history of COVID?19. The most common symptom of mucormycosis was orbital/facial pain (38.64%) and the most common sign was periocular/facial edema (50.74%). Mucormycosis involving the nose and sinuses (94.54%) was most common followed by rhino?orbital (45.41%) and brain involvement (10.04%). The most common risk factor for mucormycosis was diabetes [81.92%], followed by corticosteroid use [79.69%] and supplemental oxygen [48.90%]. Most of the patients received similar treatment with IV amphotericin B [88.64%] and local debridement [80.74%]. Conclusion: With the third wave of COVID?19 still lurking, a fatal fungal infection should be kept in mind in COVID?19 active as well as recovered patients, especially those who have co?morbid medical conditions such as uncontrolled diabetes and who are treated with large doses of corticosteroids.

Ayurvedic Management of Rhino-Orbito-Cerebral Mucormycosis in Post COVID-19 Patient: A Single Case Study

A severe and rare fungal illness, Mucormycosis also known as black fungus affecting some corona virus patient. It occurs in people with Diabetes, Hypertension, reduced immunity and immune-compromised state. Various pharmacological interventions are used for this treatment but little efficacy and its prognosis is also poor. Certain Panchakarma procedures and internal Ayurvedic medicines have been proved to be beneficial in the management of fungal sinusitis. A 79 year old male patient with complaints of sinusitis, facial and eye pain, generalized muscular pain especially over the nape of neck, right arm, and right leg, discoloration of skin, nasal congestion came to Panchakarma OPD in university college of Ayurveda, Rajasthan Ayurveda University Campus Jodhpur for treatment. The present report deals with a case of Rhino Orbito cerebral Mucormycosis managed by Panchakarma treatment along with internal medicines. The Ayurvedic diagnoses of Raktaja Pratishyaya and Krimija Shiroroga were made, and Panchakarma treatments such as Kavala/Gandusha (gargling), Nasya (nasal medication), Dhumapana and Karnapurana were performed, followed by internal medicines for 30 days. Nasyakarma is especially desired for diseases of the parts above the base of the neck (above the clavicle). This treatment method was found effective in controlling the progressive symptoms and improving the functional ability of the patient.

Retrobulbar injection of amphotericin B using intravenous cannula for post-COVID-19 rhino-orbital mucormycosis

Rhino-orbital mucormycosis has seen a huge resurgence in patients post COVID-19 infection. In patients with minimal orbital disease and especially with preserved vision, retrobulbar injections of amphotericin B can be of great help in controlling the disease. Instead of giving daily injections of amphotericin B using needles every time, we used an 18-gauge intravenous (IV) cannula with injection port and suture holes to deliver the amphotericin into the orbital space for a period of 5 days. Patients were more compliant and less distressed with this method compared with being given an injection with a needle daily. We got a good response in terms of orbital disease regression with this method. In our review of the literature, we did not come across any such case of amphotericin B injection using an IV cannula. Injection of amphotericin B into the orbit using an IV cannula is a viable and easy treatment option for cases of rhino-orbital mucormycosis

Mucormicosis orbitorrinocerebral: el manejo más allá de la cirugía. Informe de caso clínico y revisión de la literatura / Rhino-orbital-cerebral mucormycosis: management beyond surgery. Clinical case report and literature review

Introducción: se presenta el caso clínico de un paciente con mucormicosis orbitorrinocerebral y revisión de la literatura. Caso clínico: se trata de hombre de 45 años que consultó por síntomas nasosinusales manejado ambulatoriamente con múltiples antibióticos sin mejoría, por lo cual se realizó manejo quirúrgico con toma de muestras que revelaron hifas compatibles con mucormicosis. Cuando acudió a la institución presentaba extensión de la infección a todas las cavidades nasales y parte de la base del cráneo. En la búsqueda de la inmunosupresión, se encontró una diabetes de novo de difícil control. Discusión: la mucormicosis orbitorrinocerebral es una enfermedad altamente invasiva que requiere un manejo multidisciplinario, cirugías seriadas y extendidas, antimicóticos tópicos y sistémicos. El pronóstico mejora y la evolución puede ser favorable cuando se logra controlar la causa de la inmunosupresión, en este caso la diabetes. Conclusiones: es requisito fundamental realizar un tratamiento multidisciplinario en el abordaje de estos pacientes, tanto en la especialidad clínica como en la quirúrgica, psicosocial, nutricional y de rehabilitación.

Introduction: It is the clinical case of a patient with rhino-orbital-cerebral mucormycosis and the review of the literature. Clinical case: We present the case of a previously healthy young man who started with sinonasal symptoms and hyphae compatible with mucormycosis were found in the initial samples of outpatient care. When he came to the institution, the infection had spread to all the nasal cavities and part of the skull base. Discussion: Searching for baseline immunosuppression, only difficult-to-control diabetes and de novo diagnosis were found. It required multidisciplinary management, serial and extended surgeries, topical, venous and oral antifungals. The prognosis improved and the evolution became favorable when glycemic control was achieved. Conclusion: It is a fundamental requirement to carry out a multidisciplinary work for the approach to these patients, both in the clinical, surgical, psychosocial, nutritional and rehabilitation specialties.
