Wang C, Xian S, Jiang D, Huang J. Actinomycosis presenting as a nasopharyngeal mass: A case report. Oral Oncol 2024; 153:106838. [PMID: 38729038 DOI: 10.1016/j.oraloncology.2024.106838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 04/30/2024] [Accepted: 05/06/2024] [Indexed: 05/12/2024]
Abstract
Actinomycetes are predominantly pathogenic bacteria that lack aerial hyphae and do not form spores. They are generally anaerobic or facultative anaerobic Gram-positive bacteria, belonging to the prokaryotic group. Actinomycetes are widely distributed in nature, similar to other bacteria, and are mostly saprophytic, with a few being parasitic. They are named as such due to their colony's radial form. The symptoms and signs of actinomycosis are atypical and rarely manifest in the nasopharynx. Consequently, it can be challenging to distinguish actinomycosis from nasopharyngeal carcinoma, making diagnosis difficult. Histopathology is usually relied upon for diagnosis, although culture may pose challenges. Fortunately, actinomycetes are highly sensitive to penicillin. Therefore, timely treatment with high doses of penicillin is crucial for successful recovery. In this case study, we present the details of a 53-year-old female patient with no history of mucosal damage or tooth decay but with a previous partial thyroidectomy. The patient experienced recurring neck pain accompanied by progressive limitation of neck movement. Nasopharyngoscopy revealed the presence of a smooth-surfaced mass. Subsequent biopsy, clinical imaging, microbiological analysis, and histological findings confirmed the diagnosis of actinomycosis.Following a comprehensive treatment plan involving a combination of penicillin and doxycycline for a duration of two months, the disease was successfully eradicated.

Lou Y, Sun Z, Ma H, Cao D, Sun M, Wang Q, Wang J, Zhuo Q, Tao R, Ying B, Liu Y, Yu M, Wang H. Odontogenic infections in the antibiotic era: approach to diagnosis, management, and prevention. Infection 2024; 52:301-311.

Abstract
PURPOSE The prevalence of odontogenic infections remains one of the highest in the world. If untreated, odontogenic infections can break through the limitation, disseminate to other organs or spaces, and cause high mortality rates. However, it is still difficult to rapidly target limited or disseminated infections in clinical practice. The type of disseminated odontogenic infections and the responsible bacteria have not been described in detail. METHODS Search databases (e.g., PubMed, MEDLINE, Web of Science, Embase) for reports published from 2018.1 to 2022.9. Use search strategies: ("odontogenic infections" OR "pulpitis" OR "periapical lesions" OR "periodontal diseases") AND ("disseminated infections" OR "complication"). RESULTS Fourteen different types of disseminated odontogenic infections, most of which are polymicrobial infections, can spread through the body either direct or through hematogenous diffusion. Multiple microbial infections can be more invasive in the transmission of infection. Secondary infections are commonly associated with bacteria like Fusobacterium spp., Streptococcus spp., Peptostreptococcus spp., Prevotella spp., and Staphylococcus spp. Antibiotics with broad-spectrum activity are fundamental as first-line antimicrobial agents based on the microorganisms isolated from disseminated infections. CONCLUSION This review elaborates on the epidemiology, microorganisms, risk factors, and dissemination routes, and provides evidence-based opinions on the diagnosis, multidisciplinary management, and prevention of odontogenic infections for dentists and clinicians.

Abstract
We reported herein a case of isolated cerebral actinomycosis in a 54-year-old immunocompetent man. Brain MRI showed a left frontal intra-axial lesion and perilesional edema. We performed an open biopsy of the left frontal enhancing lesion. Intraoperative findings showed a yellowish, malleable, and capsulated lesion that was well defined with surrounding normal tissue within pus inside and lacked any necrotic content. MR spectroscopy showed a high level of choline, lactate, and lipid peaks with a choline/N-Acetylaspartic acid ratio of 1.8. The diagnosis was confirmed histologically, and the patient was treated successfully for 3 months after surgical aspiration. Surgical management allowed to confirm the diagnosis with a shorten antibiotics, a rapid resolution of symptoms, and a complete recovery.

Abstract
BACKGROUND Isolated Prevotella intermedia, a rare gram-negative, rod-shaped, anaerobic bacterium, is rarely detected in clinical practice. It has been associated with infections of the oral cavity and female genital tract, but has never been detected in cerebrospinal fluid (CSF) of patients in China. Accurate detection of causative pathogens is still an arduous task owing to the difficult conditions of anaerobic bacterial culture. Isolated Prevotella intermedia can be detected by metagenomic next generation sequencing (mNGS) of the CSF. Correct diagnosis and antibiotic treatment can help patients avoid life-threatening events. CASE PRESENTATION Herein, we describe the case of a 64-year-old Chinese woman who presented with typical features of meningoencephalitis. Routine CSF culture failed to identify the causative pathogen. Isolated Prevotella intermedia was detected by mNGS, and the patient was treated with antibacterial agents including ceftriaxone, vancomycin, moxifloxacin, meropenem, metronidazole, and linezolid. The patient underwent surgical treatment for abscess of left frontal parietal lobe, which was observed on magnetic resonance imaging (MRI) and was suspected to be caused by Prevotella intermedia. It was further confirmed that it was a secondary infection from the oral cavity, and the possible etiology might have been dental surgery. Treatment was rendered to the patient based on metagenomic test result, and her condition improved after two months. CONCLUSIONS This case highlights the role of mNGS in accurate diagnosis of patients with central nervous system infection. In particular, mNGS can be used to identify rare pathogens and confirm the diagnosis in patients with unknown etiology.

Abstract
Antibiotic resistance has become a major public health concern around the world. This is exacerbated by the non-discovery of novel drugs, the development of resistance mechanisms in most of the clinical isolates of bacteria, as well as recurring infections, hindering disease treatment efficacy. In vitro data has shown that antibiotic combinations can be effective when microorganisms are resistant to individual drugs. Recently, advances in the direction of combination therapy for the treatment of multidrug-resistant (MDR) bacterial infections have embraced antibiotic combinations and the use of nanoparticles conjugated with antibiotics. Nanoparticles (NPs) can penetrate the cellular membrane of disease-causing organisms and obstruct essential molecular pathways, showing unique antibacterial mechanisms. Combined with the optimal drugs, NPs have established synergy and may assist in regulating the general threat of emergent bacterial resistance. This review comprises a general overview of antibiotic combinations strategies for the treatment of microbial infections. The potential of antibiotic combinations with NPs as new entrants in the antimicrobial therapy domain is discussed.

Abstract
Rhino-orbital-cerebral mucormycosis (ROCM) is a fulminant, often fatal, angioinvasive fungal infection commonly transmitted through inhalation of fungal spores and traumatic inoculation. While the literature has documented rare cases of infection in immunocompetent patients, the vast majority of case fatalities are noted in immunosuppressed populations. Common predisposing factors to infection include immunosuppressive therapies, hematologic malignancies, and most notably, uncontrolled diabetes. Actinomycosis is a subacute to chronic bacterial infection stemming from non-spore-forming anaerobic/microaerophilic bacteria of the genus Actinomyces. Infection with Actinomyces species has been documented across numerous anatomical sites; however, literature on concurrent infection with ROCM in pediatric patients is sparse. We document a case of a 17-year-old male with uncontrolled type 1 diabetes who presented to the emergency department with combined ROCM and actinomycotic infection of his anterior skull base.

Abstract
BACKGROUND Intraparenchymal brain abscess is a collection of microbes caused by inoculation through direct extension or hematogenous spread. Although rare, intraparenchymal abscesses are potentially fatal and can be detected when patients are symptomatic due to local mass effect on adjacent neural tissue. Brain abscess treatment includes medical management with appropriate antibiotics alone or medical management in combination with surgical debridement. Treatment strategies depend on the size and location of disease, as well as the virulence of the microorganism. Similar to medical management strategies, surgical strategies among providers are not uniform, with variation in approaches from complete extirpation of the abscess, including the abscess wall, to minimally invasive stereotactic needle aspiration. In particular, for children, there are no guidelines for therapy. CASE DESCRIPTION We report a case of giant Actinomycosis right frontal brain abscess in an immunocompetent child without risk factors. A review of the literature for the treatment of brain abscess caused very rarely by Actinomyces in children is performed. CONCLUSION Successful treatment of brain access depends on organism and location. The even more uncommon giant intraparenchymal abscesses can be managed with minimal access and prolonged antibiosis, especially when slow-growing organisms are identified. Long-term follow-up should be employed to mitigate missed late failures.

Abstract
Many systemic (infective, genetic, autoimmune, neoplastic) diseases may involve the oral cavity and, more generally, the soft and hard tissues of the head and neck as primary or secondary localization. Primary onset in the oral cavity of both pediatric and adult diseases usually represents a true challenge for clinicians; their precocious detection is often difficult and requires a wide knowledge but surely results in the early diagnosis and therapy onset with an overall better prognosis and clinical outcomes. In the current paper, as for the topic of the current Special Issue, the authors present an overview on the most frequent clinical manifestations at the oral and maxillo-facial district of systemic disease.

Abstract
Background: Actinomycosis is a rare infection, frequently misdiagnosed as a neoplasia. This chronic and granulomatous disease is caused by Actinomyces israelii species. Cervicofacial actinomycosis occurs in 60% of cases and the diagnosis is commonly made by histopathology study. Case Description: We report a case of fronto-orbital osteomyelitis initially misdiagnosed as a cranial bone meningioma, but later proved to be a case of actinomycosis. 99mTechnetium (99mTc) three-phase bone single-photon emission computed tomography/computed tomography (SPECT/CT) and 99mTc-ubiquicidin (UBI) 29-41 bone SPECT/CT scans were performed to corroborate the control of the infection. Conclusion: Craniofacial actinomycosis is the most common presentation of actinomycosis. However, it continues to be a rare and difficult disease to diagnose and is often confused with a neoplastic process. The 99mTc-UBI 29-41 bone SPECT/CT scan could be an auxiliary noninvasive diagnostic alternative and a follow-up method for these patients.

Abstract
Actinomycosis is an infrequent infectious disease caused by Actinomyces species. Actinomycoses in the nasopharynx are extremely rare, especially in the Rosenmüller's fossa. This report presents a case of actinomycosis in the Rosenmüller's fossa. A 75-year-old woman presented with a 6-month history of bloody sputum. A grayish-white caseous tissue was found in the right Rosenmüller's fossa after retracting the torus tubarius. Magnetic resonance imaging showed a well-defined lesion with low-signal intensity on T1- and T2-weighted images; small low-signal areas were interspersed inside. The lesion was removed under an endoscope. Histopathological examination revealed eosinophilic, club-shaped structures surrounding a hematoxylophilic center, leading to the diagnosis of actinomycosis. The symptoms improved after 3 months of amoxicillin administration but recurred quickly. After 6 months of amoxicillin administration, the bloody sputum disappeared, and local and imaging findings were normal.

Abstract
Cervicofacial actinomycosis is an uncommon, chronic, suppurative, and granulomatous bacterial infection. It is often of dental origin and tends to mimic other dental infections, granulomatous disorders, and cancers. The initial diagnostic workup, predicated upon imaging and tissue biopsies, is frequently nonspecific. A definitive diagnosis is usually rendered only after surgical excision and histologic examination of the cervicofacial mass. We propose a classification of three stages: localized infection without sinus involvement, localized infection with sinus involvement, and disseminated infection, to facilitate recognition, diagnosis, and early aggressive treatment. Untreated infection may be life-threatening. Therapy may require long-term antibiotics; however, many cases may also necessitate complete surgical excision.

Abstract
Similarly to other non-spore-forming Gram-positive anaerobes, members of the Actinomyces genus are important saprophytic constituents of the normal microbiota of humans. Actinomyces infections are considered to be rare, with cervicofacial infections (also known as ‘lumpy jaw syndrome’) being the most prevalent type in the clinical practice. Actinomycoses are characterized by a slowly progressing (indolent) infection, with non-specific symptoms, and additionally, the clinical presentation of the signs/symptoms can mimic other pathologies, such as solid tumors, active Mycobacterium tuberculosis infections, nocardiosis, fungal infections, infarctions, and so on. The clinical diagnosis of actinomycosis may be difficult due to its non-specific symptoms and the fastidious, slow-growing nature of the pathogens, requiring an anaerobic atmosphere for primary isolation. Based on 111 references, the aim of this review is to summarize current advances regarding the clinical features, diagnostics, and therapy of cervicofacial Actinomyces infections and act as a paper for dentistry specialists, other physicians, and clinical microbiologists.

Abstract
The Fusarium species are one of the most common opportunistic fungal infections occurring in immunocompromised patients and are associated with high morbidity and mortality. Common sites of infection include blood, skin, nasal passages, lungs, bone, and other visceral organs. There is a paucity of literature on Fusarium infections in the brain, and the true nature and extent of central nervous system involvement is not well described. To the authors' knowledge, there have been no reported cases of Fusarium infection of the spine. The authors report the case of a man with acute myeloblastic leukemia and resultant pancytopenia who presented with fungal sinusitis, upper- and lower-extremity weakness, and cardiopulmonary arrest. Imaging studies revealed a spinal cervical intramedullary ring-enhancing lesion. Because of the progressive nature of his symptoms, neurosurgical intervention involving a C2-3 laminectomy and drainage of the lesion was performed. Intraoperative cultures and histopathology results were positive for Fusarium species and, along with intraoperative findings, were consistent with a fungus ball. The patient was placed on a regimen of intravenous and intrathecal antifungal therapy. Unfortunately, his clinical condition declined postoperatively, and he ultimately died of disseminated infection.

Metagenomics Approaches in Discovery and Development of New Bioactive Compounds from Marine Actinomycetes. Curr Microbiol 2019; 77:645-656. [PMID: 31069462 DOI: 10.1007/s00284-019-01698-5] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2019] [Accepted: 04/26/2019] [Indexed: 02/06/2023]
Abstract
Marine actinomycetes are prolific sources of marine drug discovery system contributing for several bioactive compounds of biomedical prominence. Metagenomics, a culture-independent technique through its sequence- and function-based screening has led to the discovery and synthesis of numerous biologically significant compounds like polyketide synthase, Non-ribosomal peptide synthetase, antibiotics, and biocatalyst. While metagenomics offers different advantages over conventional sequencing techniques, they also have certain limitations including bias classification, non-availability of quality DNA samples, heterologous expression, and host selection. The assimilation of advanced amplification and screening methods such as φ29 DNA polymerase, Next-Generation Sequencing, Cosmids, and recent bioinformatics tools like automated genome mining, anti-SMASH have shown promising results to overcome these constrains. Consequently, functional genomics and bioinformatics along with synthetic biology will be crucial for the success of the metagenomic approach and indeed for exploring new possibilities among the microbial consortia for the future drug discovery process.

Abstract
Actinomycosis of the tongue is rare. It may be difficult to differentiate this infection clinically and radiologically from other tongue pathology especially neoplasia. We report a substantial tongue lesion which mimicked malignancy at presentation. The patient was treated successfully with 4 weeks of oral antibiotic therapy. It is also important that clinicians are aware of the radiological differential diagnosis of lingual actinomycosis.

[PMID: 30069602 DOI: 10.1007/s00701-018-3633-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2018] [Accepted: 07/19/2018] [Indexed: 12/22/2022]
Abstract
BACKGROUND Due to improved diagnostic methods, the incidence of brain abscess is still rising. Therefore, clear and evidence-based therapy for the patients who suffer from brain abscesses is necessary. Brain abscesses are potentially life-threatening conditions that possibly lead to permanent injuries even after sufficient healing has taken place. The aims of this study were to analyze the clinical aspects of patients with brain abscesses and thereby to reveal the relevant aspects for the future treatment of the brain lesions. METHODS We retrospectively identified 47 patients (24 male, 23 female) who had received surgery or undergone the frameless stereotactic drainage of brain abscesses in our center from March 2009 to May 2017. We analyzed the clinical characteristics of the patients, as well as comorbidities and outcomes. RESULTS The mean age was 58 (range 7 to 86). Focus identification was successful in 28 patients (60%), with the most frequent causes of brain abscesses including the following: sinusitis (25%), dental infections (25%), and mastoiditis (21%). The mean Charlson Comorbidity Index was 1.57. Among the patients, 34% showed immunosuppressive conditions. We performed 1.5 surgeries per patient (53% via craniotomy, 28% biopsies or stereotactic drainage, 19% both procedures), followed by antibiotic treatment for 6.5 weeks (mean). In 30% of patients, no bacteria could be isolated. During the follow-up period (a median of 12 months), 23.4% of the patients died. The mortality rate during the initial hospital stay was 4.3%. CONCLUSION One third of the patients with brain abscesses showed immunosuppressive conditions, whereas brain abscesses also often occur in patients with good medical conditions. The isolation of the focus of infection is often possible. Surgical procedures showed very good outcomes. Patients over 60 years showed significantly worse clinical outcomes.
