摘要
La mucormicosis, es una patología de baja preva- lencia, rápidamente progresiva y de alta mortalidad que engloba un amplio espectro de infecciones del tipo opor- tunistas, causada por hongos de la familia Mucoraceae, Lichtheimiaceae, Thamnidiaceae, Cunninghamellaceae, Syncephalastraceae y Radiomycetaeae. Actualmente es la tercera causa de infección fúngica invasiva, posterior a la candidiasis y aspergilosos, siendo su presentación clínica más frecuente la rinocerebral de origen paranasal, cuyo síntoma característico es la rinosinusitis aguda bacteriana con proyección a los dientes antrales, de rápido avance y fatalidad. En esta revisión se emplearon resultados extraídos ma- nualmente de artículos indexados en las bases de datos MED- LINE y EBSCO a raíz de la búsqueda de los términos mu- cormycosis, oral surgery y patient care management con el objetivo de entregar una visión actualizada de la literatura, respecto al diagnóstico y tratamiento de la mucormicosis de cabeza y cuello (AU)
Mucormycosis is a low-prevalence, rapidly progres- sive and high-mortality pathology that encompasses a wide spectrum of opportunistic infections caused by fungi of the Mucoraceae, Lichtheimiaceae, Thamnidiaceae, Cunningha- mellaceae, Syncephalastraceae, and Radiomycetaeae. It is currently the third cause of invasive fungal infection, after candidiasis and aspergillosis, with its most frequent clinical presentation being rhinocerebral of paranasal origin, whose characteristic symptom is acute bacterial rhinosinusitis with projection to the antral teeth, with rapid progression and fatality. In this review, manually extracted results from articles indexed in the MEDLINE and EBSCO databases were used following the search for the terms mucormycosis, oral sur- gery and patient care management with the aim of providing an updated view of the literature regarding the diagnosis and treatment of mucormycosis of the head and neck

Los estudios sobre la infección fúngica invasiva (IFI) por Mucor spp. en pacientes pediátricos con patología hematooncológica, son de baja solidez científica, lo que dificulta conocer en profundidad sus características y evolución. Con el objetivo de analizar la evolución fatal de esos pacientes, se llevó a cabo esta revisión sistemática (RS). Material y métodos: La búsqueda bibliográfica se realizó con fecha 23 de marzo de 2023, en las principales bases de datos (Medline (a través de Pubmed), Embase (a través de Embase-Elsevier), The Cochrane Library (a través de Wiley), Cinahl (a través de Ebsco HOST), SCI-EXPANDED, SciELO (a través de la WOS) y Scopus (a través de Scopus-Elsevier), libre (mediante el motor Google) y revisando las citas de los artículos incluidos. Resultados: Se rescataron 1393 artículos, de los cuales se descartaron 1386 por diversas razones. Mediante el análisis de los textos completos, finalmente se incluyeron 7 estudios. Todos los estudios eran series de casos (nivel 4). La mediana de la frecuencia de muerte observada fue de 36,6% (Q1 20% - Q347%). Conclusiones: Esta RS mostró en niños con patología hemato-oncológica, que la mortalidad por IFI por Mucor spp. alcanzó a casi un tercio de los pacientes (AU)
Studies on invasive fungal infection (IFI) by Mucor spp. in pediatric patients with cancer have a low level of evidence, which makes it difficult to elucidate its characteristics and progression. To analyze the fatal outcome of these patients, this systematic review (SR) was conducted. Material and methods: A literature search was carried out on March 23, 2023, in the following main databases (Medline (via Pubmed), Embase (via Embase-Elsevier), The Cochrane Library (via Wiley), Cinahl (via Ebsco HOST), SCI-EXPANDED, SciELO (via the WOS) and Scopus (via Scopus-Elsevier). Additionally, a complementary search was carried out using free search engines (such as Google) and by reviewing the references of the included articles. Results: A total of 1393 articles were retrieved, of which 1386 were excluded for various reasons. After a thorough analysis of the full-text articles, 7 studies were ultimately included in the review. All studies were case series (level 4). The median observed death rate was 36.6% (IQR, 20% - 47%). Conclusions: This SR showed that in children with hematological-oncological disease, mortality due to IFI by Mucor spp. affected almost one third of the patients (AU)

COVID-19 disease is associated with a significant number of opportunistic infections, including invasive fungal infections such as mucormycosis. The prevalence of the latter is rare, estimated to be between 0.005 and 1.7 per million inhabitants. Risk factors include hematological diseases, Diabetes Mellitus with poor metabolic control, solid organ transplantation, neutropenia, and prolonged administration of systemic corticosteroids. We report two males aged 60 and 75 years with pulmonary and tracheobronchial invasive mucormycosis, respectively. Both patients had a deficient metabolic control of their diabetes as a predisposing risk factor added to severe COVID-19 infection. High suspicion and early diagnosis are essential for prompt treatment, especially considering the associated high morbidity and mortality of this fungal infection.

RESUMEN: La Mucormicosis se describe como una infección fúngica de tipo oportunista y potencialmente mortal, reportándose en la literatura como la tercera en frecuencia, muy por detrás de la Candidiasis y Aspergilosis. Esta infección es causada por hongos de la familia de los Mucorales. Se presenta el caso de un hombre con Diabetes Mellitus II con un control metabólico deficiente, el cual posterior a una exodoncia, presenta una Mucormicosis Maxilar, presentando una etiología atípica y logrando ser confirmada posterior a biopsias y pruebas de cultivo, demostrando elementos del tipo Mucor. Se realizó una Maxilectomía parcial del lado afectado como tratamiento con una evolución favorable. Esta revisión destaca la importancia de la búsqueda activa basada en la semiología y la importancia de los exámenes complementarios, implicando lograr un correcto diagnóstico y pronóstico de la enfermedad.
ABSTRACT: Mucormycosis is described as an opportunistic and life-threatening fungal infection, being reported in the literature as the third in frequency, far behind candidiasis and aspergillosis. This infection is caused by fungi of the Mucorales family. We present the case of a man with Diabetes Mellitus II with poor metabolic control who, after an extraction, presents a Maxillary Mucormycosis, with an atypical etiology and confirmed after biopsies and culture tests, demonstrating elements of the Mucor type. A partial maxillectomy was performed on the affected side as a treatment with a favorable outcome. This review highlights the importance of active search based on semiology and of complementary examinations, implying a correct diagnosis and prognosis of the disease.

Abstract The authors present seven cases of rhinocerebral mucormycosis associated to diabetes mellitus, which is a disease with epidemic proportions affecting individuals worldwide, particularly in developing countries, and which poses significant morbidity and mortality. Mucormycosis is an opportunistic fungal infection with high mortality and requires an invasive therapeutic approach to save the patient's life with significant morbidity and sequelae, thus prevention is crucial.

La mucormicosis es una infección oportunista rara usualmente fatal, que afecta mayoritariamente a personas con déficit inmunológico o patologías asociadas. Hay pocos reportes de esta enfermedad en pacientes sin los factores de riesgo tradicionales, desconociéndose aún cuáles podrían ser las causas predisponentes reales implicadas. Las formas de presentación son rinocerebral, cutánea, pulmonar, gastrointestinal y diseminada. Es por esto que, debido al difícil diagnóstico, alta mortalidad y presentación poco común reportamos el caso de un niño de 4 años sin inmunodeficiencia ni patologías de fondo que desarrolló una mucormicosis esófago-gástrica.
Mucormycosis is a rare, usually fatal, opportunistic infection that mostly affects people with immune deficiency or associated pathologies. There are few reports of this disease in patients without the traditional risk factors, still unknown what could be the real predisposing causes involved. The forms of presentation are rhinocerebral, cutaneous, pulmonary, gastrointestinal and disseminated. This is why, due to the difficult diagnosis, high mortality and uncommon presentation, we report the case of a 4-year-old child without immunodeficiency or background pathologies who developed an esophagogastric mucormycosis.

Abstract Introduction Indolent or chronic mucormycosis is a rare entity that affects both immunosuppressed and immunocompetent individuals. Additionally, its clinical evolution is nonspecific and there is no standardized treatment for this condition. Objective To describe the clinical characteristics and management of patients with indolent mucormycosis. Methods In the project of study with chart review in the Interinstitutional secondary care centers, patients with evidence of indolentmucormycosis, defined as pathological confirmation of nasal/paranasal sinus mucormycosis for more than 1 month, were included. All patients underwent complete laboratory workup, imaging studies, surgical treatment and adequate follow-up. No evidence of disease status was defined when patient had subsequent biopsies with no evidence of mucormycosis. Results We included seven patients, three female and four male subjects. The mean age was 53.14 years. Four patients were immunosuppressed and three immunocompetent. Among the immunosuppressed patients three had diabetes and one had dermatomyositis. The symptomswere nonspecific: facial pain/headache, mucoid discharge and cacosmiawere the ones most frequently reported. Maxillary sinus involvement was present in all patients. Two immunosuppressed subjects received amphotericin. Posaconazole was the only treatmentinoneimmunosuppressedpatient. Allimmunocompetent patientshadsingleparanasal sinus disease and received only surgical treatment. All patients are alive and free of disease. Conclusion Indolent mucormycosis is a new and emerging clinical entity in immunosuppressed and immunocompetent patients. Single paranasal sinus disease is a frequent presentation and should not be overlooked as a differential diagnosis in these patients. Immunocompetent patients should only be treated surgically. (AU)

Abstract We report the case of a 23-year-old immunocompetent patient who presented at the emergency department of a Brazilian hospital with epigastric pain and fever. After an investigation that included a computed tomography scan and upper gastrointestinal endoscopy with biopsy, a diagnosis of mucormycosis was established. The patient exhibited favorable progress after surgery and antifungal therapy. Mucormycosis is a rare condition that usually affects immunocompromised patients, with a high mortality rate of up to 85%. Correct diagnosis and fast initiation of therapy are required to ensure improved patient prognosis.

Resumen La mucormicosis es una infección aguda causada por hongos oportunistas pertenecientes al orden de los mucorales, que afecta principalmente a pacientes diabéticos e inmunosuprimidos. Se reporta el caso de un hombre diabético de 63 años de edad, que se extrajo una pieza dental por sus propios medios y, posteriormente, desarrolló una mucormicosis rino-órbito-cerebral con afección cutánea y palatina. La especie aislada mediante cultivos micológicos fue Rhizopus sp.
Abstract Rhino-orbito-cerebral mucormycosis from dental origin is an acute infection caused by opportunistic fungi belonging to the order of Mucorales, which affects mainly diabetic and immunocompromised patients. We report the case of a 63-year old diabetic man who performed a dental extraction on himself by his own means and subsequently developed a rhino-orbito-cerebral mucormycosis with cutaneous and palatal affection. The species isolated in the mycological culture was Rhizopus sp.

Abstract Cutaneous mucormycosis is an emerging fungal infection caused by opportunistic fungi of the phylum Glomeromycota. It is frequent in poorly controlled diabetic patients and individuals with immunosuppression. It is usually acquired by direct inoculation through trauma. The clinical presentation is nonspecific, but an indurated plaque that rapidly evolves to necrosis is a common finding. Diagnosis should be confirmed by demonstration of the etiological agent and new molecular diagnostic tools have recently been described. It is an invasive life-threatening disease and in order to improve survival, a prompt diagnosis and multidisciplinary management should be provided. The treatment of choice is amphotericin B, but new azoles, such as posaconazole and isavuconazole, must be considered.

ABSTRACT Angionvasive mucormycosis is an emerging fungal disease known to affect mainly diabetics or subjects with profound neutropenia. Infection usually occurs through the inhalation route, but cutaneous inoculation may occur after trauma or burns. However, mucormycosis remains unusual in HIV infection. We report a fatal case of cutaneous mucormycosis due to Rhizopus arrhizus involving the scalp following herpes zoster infection. The patient was a 42-year-old man with advanced AIDS failing on salvage antiretroviral therapy. The fungus was diagnosed on the basis of histopathology and culture. Our case emphasizes the need to consider mucormycosis in the differential diagnosis of necrotic cutaneous lesions in patients with late-stage HIV disease.

Abstract A 2-year-old Brazilian female child from the countryside in Bahia State presented with pain in the right flank of the abdomen, accompanied by a daily fever for about 2 weeks before admission. A large mass in the abdomen was resected by the surgical team. The biopsies revealed the mass was an intra-abdominal mucormycosis. However, the diagnosis was late, and despite treatment (amphotericin B) initiation, the patient eventually died.
