Ludwig's Angina: Higher Incidence and Worse Outcomes Associated With the Onset of the Coronavirus Disease 2019 Pandemic.

Background: Ludwig's angina (LA) is a diffuse cellulitis of the submandibular space and adjacent tissues. During the coronavirus disease 2019 (COVID-19) pandemic, odontogenic treatments were often delayed because of the implementation of safety measures to avoid the spread of the virus. We hypothesized that delayed odontogenic treatments associated with the onset of the COVID-19 pandemic would be associated with an increase in the incidence of LA and worse outcomes related to these infections. Patients and Methods: Patients from June 2018 to June 2022 with computed tomography images suggestive of LA and confirmed by ear, nose, throat (ENT) consult were included. We abstracted demographics, outcomes, clinical management, and microbiology. Patients were stratified into pre-COVID and COVID-onset. Our primary outcome, incidence of LA, was defined as: (new LA cases) ÷ (ED evaluations of oral or dental infections × 1.5 years). Results: In the pre-COVID group, we identified 32 of 1,301 patients with LA for an incidence of 0.02 per year. The COVID-onset group consisted of 41 of 641 patients, with an incidence of 0.04 per year. In the COVID-onset group, progression to necrotizing fasciitis was more likely (0% vs. 15%; p < 0.024), and they returned to the operating room for repeated debridement (3% vs. 22%; p < 0.020). Likewise, hospital length of stay, intensive care unit (ICU) length of stay, and ventilator days were higher (4.3 ± 3.5 vs. 9.5 ± 11.3; 1.1 ± 1.2 vs. 9.5 ± 7.1; 0.3 ± 1 vs. 3.6 ± 7.1; p < 0.001). Conclusions: Although the prognosis for dental infections diagnosed early is generally favorable, we observed a notable increase in the incidence of LA after the onset of the COVID-19 pandemic. Moreover, complications stemming from these infections became more severe in the COVID-onset era. Specifically, the likelihood of necrotizing fasciitis showed a substantial increase, accompanied by an increased risk of respiratory failure and mediastinitis.

Facial Swelling After Dental Work Done: A Case of Ludwig's Angina.

Ludwig's angina is a fast-spreading cellulitis located on the floor of the oropharynx and neck (Tami, Othman, Sudhakar, & McKinnon, 2020). Patients may present with a wide range of symptoms depending on the severity of the condition (Reynolds & Chow, 2007). Emergency nurse practitioners need to promptly identify, diagnose, and treat patients with this problem, with close attention to the patient's airway. A compromised airway is the leading cause of mortality from this condition (McDonnough et al., 2019). The diagnosis is generally made with a comprehensive history and physical examination, laboratory values, and imaging studies such as computer tomography (Bridwell, Gottlieb, Koyfman, & Long, 2021). Management includes admission to the hospital, broad-spectrum antibiotics, and specialist surgical consultation (Bridwell et al., 2021).

Ludwig's Angina.

Ludwig's angina is a severe diffuse cellulitis that presents an acute onset and spreads rapidly and bilaterally. It can affect the submandibular, sublingual or submental spaces resulting in a state of emergency. Early diagnosis and urgent management could be a life-saving procedure. We report a case of wide spread sialadenitis infection extending to the neck with trismus and elevation of the floor of the mouth that caused an obstruction of the airway and resulted in an inspiratory dyspnea and a stridor. The patient was directed to maintain the airway by elective tracheostomy. An appropriate use of parenteral antibiotics, airway protection techniques, and potential surgical drainage of the infection remain the standard protocol of treatment in advanced cases of Ludwig's angina. The aim of this case report is to emphasize on the importance of early diagnosis and appropriate management of Ludwig's angina.

Introduction. Ludwig angina is a rapidly progressive infectious process of the submandibular space related to pre-existing odontogenic infections. Computed tomography (CT) is useful to define thelocation and extent. Early diagnosis and management are important to avoid potentially serious complications such as airway obstruction.Case report. A 14-year-old girl presented to the emergency roomwith a 48-hour history of toothache and submandibular swelling,sialorrhea, trismus and dysphagia without associated fever. Physical examination showed caries in teeth number 46-48 and rightsubmandibular tumescence, hard and painful to the touch, whichcrossed the midline, with erythema, edema and heat. Twenty-fourhours after starting antibiotic therapy, given the worsening clinicalcondition and laboratory findings, a cervical CT scan was performed, which showed a collection compatible with abscess in thefloor of the mouth. The antibiotic therapy was changed, corticoidswere added, and the patient was referred to maxillofacial surgeryfor surgical treatment.Comments. Ludwig angina is a serious infection of the floor of themouth that should be considered in the differential diagnosis ofperiodontal infection with submandibular swelling. It is very important to know its local and systemic manifestations for an earlyintervention. (AU)

Diagnosis and management of Ludwig's angina: An evidence-based review.

BACKGROUND: Ludwig's angina is a potentially deadly condition that must not be missed in the emergency department (ED). OBJECTIVE: The purpose of this narrative review article is to provide a summary of the epidemiology, pathophysiology, diagnosis, and management of Ludwig's angina with a focus on emergency clinicians. DISCUSSION: Ludwig's angina is a rapidly spreading infection that involves the floor of the mouth. It occurs more commonly in those with poor dentition or immunosuppression. Patients may have a woody or indurated floor of the mouth with submandibular swelling. Trismus is a late finding. Computed tomography of the neck soft tissue with contrast is preferred if the patient is able to safely leave the ED and can tolerate lying supine. Point-of-care ultrasound can be a useful adjunct, particularly in those who cannot tolerate lying supine. Due to the threat of rapid airway compromise, emergent consultation to anesthesia and otolaryngology, if available, may be helpful if a definitive airway is required. The first line approach for airway intervention in the ED is flexible intubating endoscopy with preparation for a surgical airway. Broad spectrum antibiotics and surgical source control are keys in treating the infection. These patients should then be admitted to the intensive care unit for close airway observation. CONCLUSION: Ludwig's angina is a life-threatening condition that all emergency clinicians need to consider. It is important for clinicians to be aware of the current evidence regarding the diagnosis, management, and disposition of these patients.

Management of pediatric head and neck infections in the emergency department.

Head and neck infections can spread to nearby structures, compromising the airway and progressing to life-threatening events. Pediatric head and neck infections can be difficult to recognize; emergency clinicians must know the signs and symptoms of head and neck infections for early diagnosis and urgent management in order to prevent complications and decrease hospitalization rates. This issue reviews presenting signs and symptoms of pediatric head and neck infections, discusses when diagnostic studies are indicated, and offers evidence-based recommendations for management. Conditions reviewed include mastoiditis, sinusitis, Ludwig angina, peritonsillar abscess, retropharyngeal abscess, Lemierre syndrome, and acute suppurative thyroiditis.

Orofacial space infections, etiology, microbiological susceptibility and surgical management / Infecciones del espacio orofacial, etiología, susceptibilidad microbiológica y manejo quirúrgico

Orofacial infections are considered as one of most common infections and need rapid and adequate treatment as they affect a very delicate region and are associated with serious life-threatening complications. Orofacial infections can be either odontogenic that is with an origin in teeth and associated structures or non-odontogenic, not associated with teeth, can affect facial spaces and spread from one space to another, so a good knowledge about diagnosis and treating these infections is of utmost importance, and can include both non-surgical and surgical treatment. The aim of our study was to determine the most common cause of orofacial infections, the most common bacterial microorganisms and their antibiotic susceptibility. Materials and Methods: A descriptive study was undertaken in the Department of Oral and Maxillofacial Surgery, Al-Shaheed Ghazi Al-Hariry Hospital, Baghdad, Iraq from 1st January to 30th September 2015. This study included 45 patients with different forms of orofacial infections; data regarding age, gender, underlying cause, facial space involvement, presenting signs were collected through history, clinical examination and radiographs, incision and drainage with swab sample for culture and sensitivity test was performed. Results: Patients with orofacial infections showed a female to male ratio of 1.25:1. The mean age was 32.8 years. Most of the patients were in their 4th decade of life (27%). Most infections were odontogenic in origin (62%), the most common facial space involved was submandibular (65%), the most common isolated microorganism was Streptococcus pyogenes (59%), and most patients were treated using an extra-oral surgical approach (78%). Antibiotics to which bacterial isolated showed the most sensitivity were netilmicin, cefoperazone and rifampicin (91%). Pain and limitation of mouth opening gradually decreased in most of patients during the two weeks follow up period. Conclusion: Orofacial infections were more common in females, in the third and fourth decade of life, were odontogenic in origin, were mostly caused by Streptococcus pyogenes, and most isolates were susceptible to netilmicin, cefoperazone and rifampicin. Pain and trismus decreased over two weeks post-treatment.

Las infecciones orofaciales se consideran una de las infecciones más comunes y necesitan un tratamiento rápido y adecuado, ya que afectan una región muy delicada y se asocian con complicaciones graves que amenazan la vida. Las infecciones orofaciales pueden ser odontogénicas que se originan en los dientes y las estructuras asociadas, o no odontogénicas, no asociadas con los dientes, pueden afectar los espacios faciales y propagarse de un espacio a otro, por lo que un buen conocimiento sobre el diagnóstico y el tratamiento de estas infecciones es de suma importancia, y puede incluir tratamiento no quirúrgico y quirúrgico. El objetivo de nuestro estudio fue determinar la causa más común de infecciones orofaciales, los microorganismos bacterianos más comunes y su susceptibilidad a los antibióticos. Material y Métodos: se realizó un estudio descriptivo en el Departamento de Cirugía Oral y Maxilofacial, Hospital Al-Shaheed Ghazi Al-Hariry, Bagdad, Iraq del 1 de enero al 30 de septiembre de 2015. Este estudio incluyó a 45 pacientes con diferentes formas de infecciones orofaciales; Se recopilaron datos sobre edad, sexo, causa subyacente, afectación del espacio facial, signos de presentación a través de la historia, examen clínico y radiografías, incisión y drenaje con muestra de hisopo para cultivo y prueba de sensibilidad. Resultado: Los pacientes con infecciones orofaciales mostraron una relación mujer/hombre de 1.25: 1. La edad media fue de 32,8 años. La mayoría de los pacientes estaban en su cuarta década de vida (27%). La mayoría de las infecciones fueron de origen odontogénico (62%), el espacio facial más común involucrado fue submandibular (65%), el microorganismo aislado más común fue Streptococcus pyogenes (59%), y la mayoría de los pacientes fueron tratados con un abordaje quirúrgico extraoral (78%). Los antibióticos a los que las bacterias aisladas mostraron mayor sensibilidad fueron netilmicina, cefoperazona y rifampicina (91%). El dolor y la limitación de la apertura de la boca disminuyeron gradualmente en la mayoría de los pacientes durante el período de seguimiento de dos semanas. Conclusión:Las infecciones orofaciales fueron más comunes en las mujeres, en la tercera y cuarta década de la vida, fueron de origen odontogénico, fueron causadas principalmente por Streptococcus pyogenes y la mayoría de los aislamientos fueron susceptibles a la netilmicina, cefoperazona y rifampicina. El dolor y el trismo disminuyeron durante las dos semanas posteriores al tratamiento.

Ludwig's angina: a multidisciplinary concern.

Although relatively uncommon, Ludwig's angina is a potentially life-threatening infection of the floor of the mouth and neck. There is a danger of airway obstruction by swelling in the area and displacement of the tongue, and patients are at risk of deterioration. There are many factors thought to place patients at an increased risk of developing the condition. These include recent dental treatment, dental caries or generally poor dentition, chronic disease such as diabetes, alcoholism and malnutrition, and patients with compromised immune systems (eg AIDS, organ transplantation). This article examines the aetiology of Ludwig's angina and considers the presentation, diagnosis and treatment of a patient who presented to an out-of-hours streaming area of a local emergency department, with an emphasis on the importance of a multidisciplinary approach. It also considers the need for ongoing education and awareness of health professionals to ensure the successful diagnosis, management and treatment of this condition, particularly in the context of patients with poor access to dental care presenting first to the emergency department.

Infections of the Neck.

Infection of the neck is a relatively common emergency department complaint. If not diagnosed and managed promptly, it may quickly progress to a life-threatening infection. These infections can result in true airway emergencies that may require fiberoptic or surgical airways. This article covers common, as well as rare but emergent, presentations and uses an evidence-based approach to discuss diagnostic and treatment modalities.

Ludwig Angina after First Aid Treatment: Possible Etiologies and Prevention-Case Report.

Ludwig angina is a life-threatening type of soft tissue cellulitis involving 3 compartments on the floor of the mouth including the submental, sublingual, and submandibular spaces bilaterally. Prevention, early recognition, and treatment of Ludwig angina are critical because this is a clinical diagnosis with unpredictable progression. This article describes a rare case of Ludwig angina that evolved from an odontogenic infection and the specific microbiology and clinical course and discusses possible etiologies and prevention.

ENT indications for Hyperbaric Oxygen Therapy.

ENT indications for Hyperbaric Oxygen Therapy. Hyperbaric Oxygen (HBO) therapy is a treatment where patients breathe 100% oxygen while exposed to high environmental pressure in a hyperbaric chamber. This hyperoxygenation has several beneficial effects as an adjunctive treatment in a number of ENT-related conditions and diseases. These can be summarized as anti-ischaemic effects (delivery of oxygen to otherwise ischaemic tissues, reduction of ischaemia-reperfusion damage), anti-infectious effects (bacteriostasis, improved leucocyte phagocytosis bactericidal activity and optimization of antibiotic therapy) and wound-healing effects (stimulation of granulation tissue formation and stabilization). Since HBO therapy has a clear physiologic rationale, a demonstrated effect (although difficult to "prove" with placebo controlled randomized trials) in certain indications and certain side-effects, it is proposed that it should be considered an integral part of the (combined surgical and pharmacological) treatment of patients, and not simply as a supplementation of oxygen. Furthermore, the importance of a well-trained medical and technical staff to ensure proper selection and the correct follow-up of patients should not be underestimated.

Infections and edema.

Infectious and inflammatory conditions of the head and neck may present with impaired airways. An understanding of the pathophysiology will allow for accurate diagnosis and prompt intervention. Preintervention discussion and planning by members of the airway team are crucial in developing a primary and backup plans for safely securing the airway.

Longitudinal discharge trends and outcomes after hospitalization for mouth cellulitis and Ludwig angina.

OBJECTIVE: Objective is to provide longitudinal discharge trends and hospitalization outcomes in patients hospitalized because of mouth cellulitis or Ludwig angina. METHODS: Nationwide Inpatient Sample for years 2004 to 2010 was used. All hospitalizations with primary diagnosis of cellulitis or Ludwig angina were selected. Discharge trends were examined. RESULTS: A total of 29,228 hospitalizations occurred as a result of mouth cellulitis/Ludwig angina; 55% of all hospitalizations were male patients; 68% were aged 21 to 60 years. Non-whites comprised close to 40%. The uninsured comprised 22.3%. Ninety-nine patients died in hospitals. The total hospitalization charges across the entire United States over the study period was $772.57 million. Factors associated with increased hospitalization charges included, age, co-morbid burden, insurance status, race, teaching status of hospital, and geographic location. CONCLUSIONS: Uninsured non-whites, those with high co-morbid burden, and those aged 21 to 60 years tended to be hospitalized consistently over the study period.
