Abstract
Mucormycosis caused by Lichtheimia ramosa is an emerging and uncommon opportunistic infection in patients with hematological malignancies, with high mortality rates. Herein, we first report a case of pulmonary mucormycosis with Lichtheimia ramosa in a 3-year-old girl recently diagnosed with B-cell acute lymphoblastic leukemia. The diagnosis was made using computerized tomography of the lung, metagenomic next-generation sequencing (mNGS) of blood and sputum specimens, and microscopic examination to detect the development of Lichtheimia ramosa on the surgical specimen. She was effectively treated after receiving prompt treatment with amphotericin B and posaconazole, followed by aggressive surgical debridement. In our case, the fungal isolates were identified as Lichtheimia ramosa using mNGS, which assisted clinicians in quickly and accurately diagnosing and initiating early intensive treatment. This case also indicated the importance of strong clinical suspicion, as well as aggressive antifungal therapy combined with surgical debridement of affected tissues.

[PMID: 35783622 PMCID: PMC9248758 DOI: 10.3389/fmed.2022.851208] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2022] [Accepted: 05/06/2022] [Indexed: 12/02/2022] Open
Abstract
Background Extranodal natural killer/T-cell lymphoma, nasal type is a syndrome of middle face destruction with an association to Epstein-Barr virus. Fungi have been recovered from the diseased tissue now and then but were often seen as a lymphoma-associated secondary infection. However, there are ENKTL-NT cases with the recoveries of fungi and complete recovery with antifungal therapy, which are quite similar to rhino-orbital-cerebral mycosis (ROCM) that often confuses the physicians. Methods We searched Medline for English-language manuscripts limited to “human” and “case reports,” “letters,” “reviews,” and “clinical conferences” from 1966 to 2022. We used MeSH terms “lymphoma, extranodal nk-t-cell” [MeSH Terms] or “lethal midline granuloma” [MeSH Terms], in combination with MeSH terms “microbiology” [subheading] or “microbiology” [all fields] or “fungi” [all fields] or “fungi” [MeSH Terms] for ENKTL-NT with infections. We used MeSH terms “Mycoses” in combination with “Nose” [Mesh] OR “Orbital Diseases” [Mesh] for rhino-orbital-cerebral fungal infections. Results We appraised 149 included articles and extracted references related to ENKTL-NT and/or ROCM. Themes and subcategories were subsequently derived. Our findings revealed that ROCM and ENKTL-NT are characterized by progressive and destructive ulcers in the midline face or rhino-orbital structures. ROCM is mainly caused by fungi in the order of Mucorales, and ENKTL-NT is usually associated with Epstein-Barr virus and sometimes fungi. Radiologically, both are characterized by non-specific features of sinusitis, soft tissue infection, and necrosis. Pathologically, ROCM and ENKTL-NT share the same characteristics of inflammation, necrosis, and granuloma. ROCM is characterized by the detection of fungi in tissue, while ENKTL-NT is typically positive for NK/T-cell markers and cytotoxic granule-associated proteins, proliferation, and vascular damage of angioinvasion, which could be incited by Mucor irregularis and Rhizopus arrhizus in patients and mice. Conclusion ENKTL-NT and ROCM share many similarities in clinical presentations, radiology, and histopathology, and might have the same etiology. This may explain why the two diseases are tangled together in the reported cases, and suggests the role that the fungi may play in the development of these ENKTL-NT/ROCM diseases. The reason why ENKTL-NT and ROCM are sometimes confused is that the main pathogens of ROCM, Mucor irregularis and Rhizopus arrhizus, are the fungal causative agents of ENKTL-NT.

Abstract
Rhino-orbital-cerebral mucormycosis is a severe and rapidly progressive fungal infection associated with low survival rates. Early diagnosis and proper management are mandatory. We report the case of a 20-year-old female with diabetic ketoacidosis and teeth infection, who presented with sudden orbital apex syndrome. Several surgical procedures were necessary to provide a definite histopathological diagnosis of the fungal infection. Ultimately, given the progressive aggravation of the infection and the ineffectiveness of antifungal and antibiotic agents, an orbital exenteration was performed. A mycobacteriological examination revealed a polymicrobial culture with Mucorales. One year after the initial presentation, the patient is alive and with a good general health condition.

Abstract
BACKGROUND AND PURPOSE Rhino-orbito-cerebral mucormycosis (ROCM) is a rare and potentially fatal invasive fungal infection which usually occurs in diabetic and other immunocompromised patients. This infection is associated with high morbidity and mortality rates. Prompt diagnosis and rapid aggressive surgical debridement and antimycotic therapy are essential for the patient's survival. Herein, we reviewed the localization and treatment strategies in patients with ROCM and diabetes as an underlying condition. Furthermore, we report one case of ROCM in our department. MATERIALS AND METHODS From 117 identified studies published in PubMed, 14 publications-containing data from 54 patients-were included. All patients were diagnosed clinically and by histopathological and/or bacteriological analysis for ROCM caused by the order Mucorales. CONCLUSION Uncontrolled diabetes mellitus is one of the main risk factors for ROCM. A successful management of ROCM requires an early diagnosis, a prompt systemic antifungal therapy, and a rapid aggressive surgical debridement including exploration of the pterygopalatine fossa. An orbital exenteration may be necessary.

Abstract
In the recent years, the epidemiology of invasive fungal infections (IFIs) has changed worldwide. This is remarkably noticed with the significant increase in high-risk populations. Although surveillance of such infections is essential, data in the Middle Eastern and North African (MENA) region remain scarce. In this paper, we reviewed the existing data on the epidemiology of different IFIs in the MENA region. Epidemiological surveillance is crucial to guide optimal healthcare practices. This study can help to guide appropriate interventions and to implement antimicrobial stewardship and infection prevention and control programs in countries.

Abstract
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.

Abstract
Squamous cell carcinoma of the oral (mobile) tongue (OMTC), a non-human papilloma virus-associated oral cancer, is rapidly increasing without clear etiology. Poor oral hygiene has been associated with oral cancers, suggesting that oral bacteriome (bacterial community) and mycobiome (fungal community) could play a role. While the bacteriome is increasingly recognized as an active participant in health, the role of the mycobiome has not been studied in OMTC. Tissue DNA was extracted from 39 paired tumor and adjacent normal tissues from patients with OMTC. Microbiome profiling, principal coordinate, and dissimilarity index analyses showed bacterial diversity and richness, and fungal richness, were significantly reduced in tumor tissue (TT) compared to their matched non-tumor tissues (NTT, P<0.006). Firmicutes was the most abundant bacterial phylum, which was significantly increased in TT compared to NTT (48% vs. 40%, respectively; P=0.004). Abundance of Bacteroidetes and Fusobacteria were significantly decreased in TT compared to matched NTT (P≤0.003 for both). Abundance of 22 bacterial and 7 fungal genera was significantly different between the TT and NTT, including Streptococcus, which was the most abundant and significantly increased in the tumor group (34% vs. 22%, P<0.001). Abundance of fungal genus Aspergillus in TT correlated negatively with bacteria (Actinomyces, Prevotella, Streptococcus), but positively with Aggregatibacter. Patients with high T-stage disease had lower mean differences between TT and NTT compared with patients with low T-stage disease (0.07 vs. 0.21, P=0.04). Our results demonstrate differences in bacteriome and mycobiome between OMTC and their matched normal oral epithelium, and their association with T-stage.

Abstract
Mucormycosis is an acute necrotic fungal infection with a fulminant course. Earlier considered a rare entity, mucormycosis is being reported with increasing frequency in recent years, possibly due to the increase in immunocompromised population especially diabetic patients. We report three cases of rhinocerebral mucormycosis among poorly controlled diabetic patients. This article emphasizes the need for further awareness of this disease, early diagnosis, and treatment to counter this opportunistic infection.

Abstract
In this case report, we present the clinical findings and therapeutic outcomes of four rhino-orbital mucormycosis patients. The four patients (1 female, 3 male; age range, 55-77 years) all had diabetes mellitus and two also had chronic renal failure. All patients exhibited proptosis, sinusitis, and dark-colored lesions on the nasopharynx and/or hard palate; three patients had ipsilateral peripheral facial paralysis. Visual acuity was no light perception in the two patients with severe orbital involvement and 0.8 in two patients with limited orbital involvement. Histopathological examination of the hard palate, nasopharynx or sinus biopsy revealed typical Mucor hyphae. Systemic liposomal amphotericin B was initiated in all patients. The patients with limited ocular involvement received amphotericin B both intravenously and by local irrigation; both patients had complete recovery. The other two patients underwent orbital exenteration; one patient died after declining systemic treatment postoperatively. Rapid diagnosis and treatment are important for the survival of rhino-orbital mucormycosis patients. With orbital involvement, surgical debridement and systemic and local treatment with antifungal agents may help avoid mutilating surgery like exenteration.
