Lemierre's syndrome: case report in a pediatric patient

Infectious Brachial Plexopathy and Septic Arthritis of the Shoulder due to Lemierre's Syndrome: A Case Report and Literature Review

CASE

We present a 20-year-old female with Lemierre's syndrome and an associated infectious brachial plexopathy and missed septic shoulder arthritis. She subsequently presented with advanced post-infectious glenohumeral joint arthritis. At the final 12-month follow-up, substantial shoulder pain and dysfunction persisted.

CONCLUSIONS

When Lemierre's syndrome has been diagnosed, patients with upper extremity symptoms suggestive of metastatic infection require a thorough assessment to rule out musculoskeletal involvement and site-specific intervention to prevent long-term morbidity.

Bacteremia and sepsis by Arcanobacterium haemolyticum in a young immunocompetent patient

We report the case of a twenty-year-old immunocompetent male patient presenting to the emergency room with pharyngitis and fever. Blood cultures were drawn and Arcanobacterium haemolyticum (rough biotype) was recovered. The presence of the arcanolysin gene was investigated at the molecular level and the upstream region was amplified and sequenced in order to correlate it with the smooth or rough biotype. Although the isolate was susceptible to penicillin, vancomycin and gentamicin, empirical treatments first with amoxicillin/clavulanic acid (1g/12h) and then with ceftriaxone (1g/12h) failed and the infection evolved to sepsis. Finally, treatment with vancomycin (1g/12h) plus piperacillin/tazobactam (4.5g/8h) was effective. Lemierre's syndrome was ruled out. To the best of our knowledge, this is the first case of bacteremia by A. haemolyticum reported in Argentina.

Neonatal Lemierre Syndrome: Youngest Reported Case and Literature Review

A previously healthy 5-week-old female was admitted for sepsis secondary to methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. After several days of hospitalization, she experienced acute decompensation in mental status despite having received targeted antibiotic therapy. Imaging revealed left peritonsillar/parapharyngeal space abscess, left venous thrombophlebitis of the internal jugular vein, and septic emboli of the lungs and brain consistent with Lemierre syndrome. Bedside needle aspiration of the parapharyngeal abscess confirmed MRSA involvement. Unfortunately, the patient continued to deteriorate over the next several days and life support was withdrawn on hospital day 16. We present the youngest reported case of Lemierre syndrome and review the literature.

Fusobacterium necrophorum otitis and mastoiditis in infants and young toddlers

There is an increased recovery of Fusobacterium necrophorum from cases of otitis media and mastoiditis in the pediatric population. These infections may be highly severe, causing local osteomyelitis, bacteremia, and Lemierre's syndrome. The severity and difficulties in providing optimal treatment for these infections may be especially difficult in this age group due to immunological immaturity and delayed presentation. In this review of literature, we present and analyze the clinical presentation, management, and outcome of otic infections caused by F. necrophorum in infants and young toddlers less than 2 years old. Search in Pubmed was conducted for reported cases in the English literature for the time period of the last 50 years. Twelve well-described cases were retrieved with F. necrophorum otitis and mastoiditis and complications reported in all cases. Treatment included both intravenously with antimicrobial agents (beta lactams plus metronidazole) and mastoidectomy. Lemierre's syndrome and Lemierre's syndrome variants developed in 60 % of the patients. Dissemination of the infection as distal osteomyelitis and septic shock were also reported. The outcome was favorable in all the cases. Otitis and mastoiditis infections in children less then 2 years old are invasive infections, and severe complications can occur.

Lemierre's syndrome: A systematic review

OBJECTIVES/HYPOTHESIS

Lemierre's syndrome is characterized by a history of recent oropharyngeal infection, clinical or radiological evidence of internal jugular vein thrombosis, and isolation of anaerobic pathogens, mainly Fusobacterium necrophorum. It was once called the forgotten disease because of its rarity, but it may not be that uncommon after all. This review aims to provide physicians with an update on the etiology, management, and prognosis of Lemierre's syndrome.

METHODS

Systematic review using the terms: Lemierre's syndrome, postanginal septicemia, fusobacterium, internal jugular vein thrombosis.

INCLUSION CRITERIA

English literature; reviews, case reports, and case series.

EXCLUSION CRITERIA

variants or atypical Lemierre's syndrome cases, negative fusobacteria cultures, and papers without radiological evidence of thrombophlebitis.

RESULTS

Eighty-four studies fulfilled our inclusion criteria. The male to female ratio was 1:1, 2, and the ages ranged from 2 months to 78 years (median, 22 years). Main sources of infection were tonsil, pharynx, and chest. Most common first clinical presentation was a sore throat, followed by a neck mass and neck pain. The most common offending micro-organism was F. necrophorum. Treatment modalities used were antimicrobial, anticoagulant, and surgical treatment. Morbidity was significant with prolonged hospitalization in the majority of patients. The overall mortality rate was 5%.

CONCLUSIONS

Lemierre's syndrome may not be as rare as previously thought. This apparent increase in the incidence may be due to antibiotic resistance or changes in antibiotic prescription patterns. Successful management rests on the awareness of the condition, a high index of suspicion, and a multidisciplinary team approach.

Méningite à Fusobacterium necrophorum: complication oubliée d'une gingivite

By now Lemierre's syndrome is a seldom-described disease whose prognosis depends on the precocity of treatment.

CASE PRESENTATION

We report the case of an 11-month-old child, with a fulminant Fusobacterium necrophorum meningitis, which derived from a gingival infection, with fatal outcome.

CONCLUSION

This atypical case of Lemierre's syndrome (young age occurrence and localisation) underlines the potential severity of F. necrophorum sepsis.
