Treatment of Cervicofacial Actinomycosis: A report of 19 cases and review of literature

Objectives: Actinomycosis is a chronic suppurative granulomatous infection caused by the Actinomyces genus. Orocervicofacial actinomycosis is the most common form of the disease, seen in up to 55% of cases. All forms of actinomycosis are treated with high doses of intravenous penicillin G over two to six weeks, followed by oral penicillin V. Large studies on cervicofacial actinomycosis are lacking. Therefore proper guidelines for treatment and treatment duration are difficult to establish. The aim of this study is to establish effective treatment and treatment duration for orocervicofacial actinomycosis. Study design: A Pubmed and Embase search was performed with the focus on treatment and treatment duration for cervicofacial actinomycosis. The hospital records of all patients presenting to our department with head and neck infection from January 2000 to December 2010 were reviewed, retrospectively. The following data were collected: age, gender, clinical presentation, aetiology, duration of symptoms, microbiological findings, treatment, and duration of treatment. The treatment and treatment duration is subsequently compared to the literature. Results: The literature search provided 12 studies meeting the inclusion criteria. All studies were retrospective in nature. Penicillin or amoxicillin/clavulanic acid are the preferred antibiotic regimens found in the literature. Most of our patients were treated with a combination of penicillin G 12 million units/day and metronidazol 500 mg 3/day, most commonly for a duration of 1 – 4 weeks, being shorter than the 3 – 52 weeks reported in the literature. Conclusion: When actinomycosis is suspected, our review has shown that a surgical approach in combination with intravenous penicillin and metronidazol until clinical improvement is seen, followed by oral antibiotics for 2 – 4 weeks is generally efficient. Key words:Actinomycosis, actinomyces, actinomycosis treatment, cervicofacial infection, actinomycosis diagnosis, head and neck infection.     

Atypical presentations of pediatric actinomycosis: report of a case

It is well recognized that cervicofacial actinomycosis is rare in children, especially at maxilla. Actinomycosis involving the maxilla usually is seen as a localized intraoral infection in contrast to classical cervicofacial actinomycosis. In this article, we describe an 8-year-old patient who had actinomycosis involving the bone at the left maxillary lateral incisor region. The diagnosis was based on histologic report because of location and development of the lesion with unusual history. The treatment of choice was removal of the soft and hard tissues with concomitant prolonged penicillin administration. In cases of persistent oral infection the diagnosis of actinomycosis should be actively attempted through microbiologic and histologic examination.     

Cervicofacial necrotizing fasciitis: report of three cases and literature review

Three cases of cervicofacial necrotizing fasciitis have been reported, two of dental etiology, and one the result of blunt and abrasive facial trauma. All cases responded well to aggressive surgical intervention in combination with broad spectrum antibiotic coverage and supportive medical therapy. The presence of increased vascularity in the head and neck region probably minimizes the amount of overlying soft tissue that must be excised during surgical management (in comparison to extremity and trunk necrotizing fasciitis cases). The key to successful management of such infections is early diagnosis of the disease process with prompt surgical and medical intervention.     

Cervicofacial actinomycosis: A diagnostic challenge

Actinomycosis was first described as a clinical entity over 100 years ago. However, the fundamental characteristics of this entity have not been fully discussed, and major questions remain unanswered, such as the highly diversified pathogenicity of the phenomenon according to numerous published case reports and clarification of solid diagnostic criteria. Even the frequency of cervicofacial actinomycosis occurrence is unclear; some authors consider it to be rare and others to be common. We present 11 cases examined and treated in our department within the last 14 years along with a review of the literature. Diagnostic problems are emphasized, and a comprehensive overview of the entity is suggested.     

Facial actinomycosis mimicking a desmoid tumour: case report

Actinomycosis is a chronic, suppurative, granulomatous, fibrosing infection that usually occurs in the cervicofacial region. Actinomyces israelii is the most common organism, with sporadic cases being caused by A. odontolyticus. Even though actinomyces are part of the normal oral flora, infections are rare; rarer still is actinomycotic infection of the facial skin. We describe a case of actinomycosis of the skin of the chin, which histologically mimicked a desmoid tumour.     

Actinomyces parotid infection after mandibular third molar extraction

Actinomycosis is currently an uncommonly diagnosed human disease. The disease is a chronic suppurative infection caused by micro-organism from the Actinomyces group, most often Israelii. A patient with cervicofacial actinomycosis generally reports a history of recent dental treatment which, usually, involves extraction of a mandibular molar. The common initial signs and symptoms of infection (such as sudden onset of cervicofacial pain, swelling, erythema, edema and suppuration) can be absent. In this case report a 29-year-old man presented a mass in his left parotid area, 1 week after mandibular molar extraction. Echography and CT scans revealed a parotid abscess area. The needle-biopsy of swelling revealed infection due to Actinomyces. Therapy was started with intravenous cefazolin (fl 1g X 2 in 100 s.s. i.v.) and methylprednisolone (25 mg tablet, 1/die) for 9 days; 14 days after treatment suspension the lesion reappeared with a fistula and a new therapy was given (ceftriaxone 1 g/die and gentamicin 80 mg/i.m. for 3 weeks). To prevent a relapse, the patient received cefalexin 1 gx2/die per os for 4 weeks. After a follow-up of 1 year, the patient was still asymptomatic.     

An unusual manifestation of actinomycosis infection of the maxilla

Postoperative actinomycosis infection caused by Actinomyces israelii is uncommon. Cervicofacial actinomycosis may appear as an opportunistc infection in the oral cavity. Initial diagnosis of this condition is difficult after oral surgery and the condition often is mistaken for more common odontogenic infections. Actinomycosis responds to antibiotic therapy but the condition recurs after therapy is discontinued. This article presents an unusual case of postsurgical actinomycosis that manifested in the cheek and appeared to be unrelated to the surgical extraction of an impacted maxillary third molar that had occurred one year earlier. The organism was sampled under anaerobic conditions, isolated, and diagnosed by Gram's stain and culture tests. The condition was cured after extraoral surgical drainage, debridement, and several months of oral antibiotic administration.     

Periapical actinomycosis: a clinicopathologic study

OBJECTIVE: We sought to evaluate the incidence and clinical outcome of an accidental finding of actinomycotic colonies in periapical lesions submitted for histologic examination. STUDY DESIGN: The study included all periapical biopsy specimens submitted for histologic examination between 1997 and 2000. Sections of paraffin-embedded tissues, 5 microm, were cut and stained by using hematoxylin and eosin, periodic acid-Schiff, and the Gram stain. The presence of typical branching colonies of filamentous bacteria staining positive for periodic acid-Schiff and Gram stain was indicative of Actinomyces. RESULTS: Typical actinomycotic colonies were identified in 17 of 963 (1.8%) periapical biopsy specimens. The mean patient age was 42, and males were predominant (65%). The maxilla was the most frequently involved site (65%), with equal distribution in the anterior and posterior areas. Radiographically, most cases presented as well-demarcated radiolucent lesions. Malignancy was suspected in 3 cases. Of the periapical lesions, 15 were epithelialized, and in 4 cases, a true epithelial-lined lumen was found, which was diagnosed as a radicular cyst. A residual cyst was diagnosed in 1 case, and in 1 case, an epithelial lining was not identified. Treatment included surgical curettage and a short course of antibiotic therapy. Healing was uneventful in all cases. CONCLUSIONS: Periapical actinomycosis is not common. Its outcome is favorable after surgical curettage supplemented by short-term antibiotic treatment. The relationship of periapical actinomycosis with the more serious cervicofacial actinomycosis should be evaluated.     

Rare lesions of the oral cavity: case report of an actinomycotic lesion limited to the gingiva

Actinomycosis is an infectious disease that frequently has chronic granulomatous and suppurative lesions caused by saprophytic Actinomyces species. Although cervicofacial actinomycosis is known to be the most common type, intraorally and periodontally types occur rarely in a localized fashion. The present case reports on an adult periodontitis patient with a diffuse and atypic actinomycotic lesion which was limited to the gingiva and had an abscess formation, a large desquamation and subsequent exposure of the alveolar bone in the involved region. Diagnosis was based on histopathological examination, the history of the case and clinical nature of the lesion. The patient responded to daily administration of 100 g doxcycycline (first day-bid) for 3 weeks and 0.2% chlorhexidine gluconate irrigation (following tooth brushing) performed with oral hygiene reinforcement and periodontal debridement procedures. Complete improvement of the lesion was observed after 5 weeks. Due to the opportunistic characteristics of the actinomycotic infection, early and adequate differential diagnosis of actinomycosis prior to therapeutic attempts, as well as management steps, are of great importance in the oral cavity to prevent the spread of the disease.     

Periapical actinomycosis: a review.

Actinomycosis has increasingly been recognized as a cause of persistent or recurrent periapical disease associated with endodontically treated teeth. This case report shows the classic clinical picture of periapical actinomycosis: persistent periapical disease with recurrent sinus tracts. Although there was no pain or swelling after clinically acceptable initial endodontic treatment, a periapical lesion developed. After retreatment, the periapical lesion persisted, and a sinus tract developed. The sinus tract healed with antibiotic therapy but recurred within a few months. This cycle of sinus tract to antibiotic therapy to recurrence of the sinus tract repeated several times over a period of 5 years. Upon biopsy, periapical actinomycosis was diagnosed, where classic "sulfur granules" were demonstrated in the histologic examination of the periapical lesion. Antibiotic therapy for a period of 6 weeks was prescribed subsequent to the histologic diagnosis because of the possibility of spread of the actinomycotic infection into the maxillary sinus. Considerable healing was evident within 5 months of surgical and antibiotic treatment.     

Acute cervicofacial necrotizing fasciitis: three clinical cases and a review of the current literature

Cervicofacial necrotizing fasciitis (NF) is a rare condition that can quickly become life-threatening if appropriate treatment is delayed. This condition is observed as a rapidly progressive infection that causes extensive necrosis of the superficial fascia. This report presents a case of cervicofacial NF with microbiological isolation of methicillin-resistant Staphylococcus aureus in a patient with a history of uncontrolled diabetes mellitus following a minor scalp trauma. The article also presents two cases of NF secondary to odontogenic infection. The radiographic finding of the presence of gas locules in the facial planes on the CT scan helped to confirm the diagnosis. Patients were treated with broad-spectrum antibiotic therapy, extensive surgical drainage, debridement, and supportive care. Awareness in the dental community of the signs of NF will facilitate optimal patient management.     

Treatment of Lymphangioma of the Face with Intralesional Bleomycin: Case Discussion and Literature Review

Surgical treatment of lymphangioma of the face is a difficult task to achieve due to close vicinity of the lesion to the facial nerve and possibility of scar tissue formation. Inefficient surgical removals generally will give rise to high recurrence rates because of infiltrative and diffuse extension of the lesion. However, complete cure has been described by non-surgical methods. A 5-year-old girl with extensive lymphangioma of the left cervicofacial area was treated with intralesional bleomycin injection under ultrasonographic guidance. Case discussion and related literature review was presented.     

Patterns of cervicofacial infections: analysis of the use of computed tomography

Objective

The aim of this study was to determine which clinical, microbiological and radiological factors contribute to the need for repeated computed tomography (CT) imaging and surgical drainage.

Methods

In this retrospective study, medical records of all patients who underwent surgical drainage of cervicofacial infections between January 2006 and August 2010 at a London tertiary referral centre were analysed. Patients who underwent CT due to a clinical suspicion of deep cervicofacial infection were divided into two groups: (1) single CT only and (2) repeated CT imaging. These groups were then compared using Fisher’s exact test. Patients requiring return to theatre for additional exploration and drainage of collection were also analysed.

Results

Four hundred and forty-five patients were admitted with cervicofacial infections, of whom 78 patients had a CT scan. The most frequent site of infection was the submandibular space, involving 54 % of patients. Among the patients who underwent repeated imaging compared to those who underwent a single CT scan, the parapharyngeal space was involved significantly more frequently (5/24 vs 2/54, p?=?0.03), as was the presence of multiple-space infections (13/24 vs 15/54, p?=?0.04) and osteomyelitis (4/24 vs 0/54, p?=?0.007). Multiple-space infection was also more frequent in the group who required repeat visits to theatre as compared to those who had a single drainage (7/9 vs 23/69, p?=?0.02).

Conclusions

The majority of cervicofacial infections are managed without the need for CT scanning. Presence of infection in multiple cervicofacial spaces and in the parapharyngeal space and presence of osteomyelitis result in persistent sepsis necessitating repeat imaging and drainage.     

Systematic review of the role of corticosteroids in cervicofacial infections

The role of corticosteroids in the management of cervicofacial infections continues to cause controversy. Systemic anti-inflammatory and immunomodulatory effects that reduce swelling and improve symptoms in the head and neck may make these agents an effective addition to the antibiotics used and to surgical management, although this same effect may dull the physiological response to infection, and allow infections to progress. We have systematically reviewed the evidence for the use of corticosteroids in common cervicofacial infections following the PRISMA guidelines. MeSH terms included “head”, “neck”, “infection”, and “glucocorticoid”. In total, 31 papers were identified. Eight reported the use of corticosteroids for peritonsillar abscess (PTA), 10 for pharyngitis, four for deep neck space infection (DNSI), four for periorbital cellulitis, and five for supraglottitis. Whilst there is an established evidence base for their use in the treatment of PTA and pharyngitis, other indications need further study, and we highlight the potential pitfalls. The evidence suggests that the use of adjunctive, short-term, high-dose corticosteroids in cervicofacial infections may be safe and effective.     

Case 39, part II: Cervicofacial actinomycosis

A case is presented that was unusual in its clinical manifestation. The firm, nontender, submental mass showed no evidence of erythema or fluctuation. It did not respond to intravenous antibiotic therapy until after it had been drained surgically. The apparent source of infection was a chronic periodontal lesion involving tooth No. 18. The patient gave no history of discomfort involving tooth No. 18 or his left mandible.In many respects, the case is a classic one of actinomycosis. The lesion was slow growing, hard, and nontender. Like the majority of the cases in the literature it involved the cervicofacial region. The infection began to resolve rapidly following surgical drainage and debridement. The lesion was identified surgically as an abscess with a central necrotic area surrounded by granulation tissue and firm fibrous tissue, all of which are hallmarks of actinmycosis.After two months of oral penicillin G therapy, the patient was free of any evidence of disease.     

Necrotizing fasciitis of the maxillofacial region caused by dental infection. A case report and review

Necrotizing fasciitis (NF) is a destructive and potentially fatal soft tissue infection characterized by extensive necrosis and gas formation in subcutaneous tissues and fascia, with serious involvement of muscles, vessels, nerves, and fat. In the maxillofacial region, NF is less common. The process can represent the evolution of a dental infection supported by aerobic and anaerobic bacteria that are resistant to antibiotic therapy (multidrug resistance) in immunocompromised patients or the natural evolution of untreated infection. Because of the rarity of the disease, diagnosis and treatment are often delayed, which may result in a fatal outcome due to respiratory problems or systemic complications. The success of the treatment is surgical debridement and high doses of antibiotic therapy. The AA described a case of NF in a female, 59 years old, who developed NF in the maxillofacial and neck region following dental infection and after consulting our Institute for remarkable swelling of the right cheek, palpebral and parotid regions, submaxillary region, and neck; this swelling is associated with hyperpyrexia, trismus, poor systemic conditions, and serious respiratory difficulty. Through prompt clinical diagnosis, early surgical treatment, appropriate antibiotic therapy (culture analysis revealed sensitivity to Imipenem and Levofloxacina), and local control of the lesion through surgical medications twice daily, we were able to not only avoid serious and fatal evolution of the process, but also to limit tissue involvement, preventing further extension of the necrosis to other anatomical structures of the region. A satisfactory clinical result was thus obtained.     

Sclerosing osteomyelitis of Garré periostitis ossificans

Sclerosing osteomyelitis of Garré is a rare syndrome; the mandible is the most commonly affected bone segment in the cervicofacial region. This chronic disease is characterized by a nonsuppurative ossifying periostitis with subperiosteal bone formation, commonly reactive to a mild infection or irritation. The differential diagnosis must be made with similar clinical conditions with hard mandibular swelling associated with bony sclerosis. Presumptive diagnosis can be achieved by radiology, but such diagnosis must be confirmed by histology. The aim of therapy is to remove the cause when recognized, aided by an adequate antibiotic therapy. Clinical, radiographic, and histologic features are presented in this case report.
