“…Thirty-seven of these 53 articles were not included because they had a different focus, that is, laboratory methods, 17 or focused on a different category of patients than was the scope of this review: chronically ill patients, 18 hospitalised patients, 19–24 or patients with a subset of infections such as PTA, Lemierre’s syndrome, chronic/recurrent tonsillitis and intra-abdominal infections. 11 25–52 Four were excluded because they lacked a control group. 53–56 Discussions in the review team prompted the exclusion of another five articles with methodological limitations in relation to the scope of this review.…”

“…[7][8][9] FN is an anaerobic Gram-negative bacterium most known for causing the severe disease Lemierre's syndrome, a potentially life-threatening condition that typically begins with a sore throat and is also an established pathogen in peritonsillar abscess (PTA). [10][11][12] The role of FN in the sore throat has been studied in three recent reviews. [7][8][9] None of the three reviews have taken into consideration the carriage rate of FN in healthy controls, which is of importance when estimating the clinical relevance of finding FN in patients with an uncomplicated acute sore throat.…”

Acute sore throat and Fusobacterium necrophorum in primary healthcare: a systematic review and meta-analysis

PurposeThe main objective of this review was to describe and quantify the association between Fusobacterium necrophorum (FN) and acute sore throat in primary healthcare (PHC).MethodsIn this systematic review and meta-analysis, we searched Scopus and PubMed for case–control studies reporting the prevalence of FN in patients attending primary care for an uncomplicated acute sore throat as well as in healthy controls. Only studies published in English were considered. Publications were not included if they were case studies, or if they included patients prescribed antibiotics before the throat swab, patients with a concurrent malignant disease, on immunosuppression, having an HIV infection, or patients having another acute infection in addition to a sore throat. Inclusion criteria and methods were specified in advance and published in PROSPERO. The primary outcome was positive etiologic predictive value (P-EPV), quantifying the probability for an association between acute sore throat and findings of FN in the pharynx. For comparison, our secondary outcome was the corresponding P-EPV for group A Streptococcus (GAS).ResultsPubMed and Scopus yielded 258 and 232 studies, respectively. Removing duplicates and screening the abstracts resulted in 53 studies subsequently read in full text. For the four studies of medium to high quality included in the meta-analysis, the cumulative P-EPV regarding FN was 64% (95% CI 33% to 83%). GAS, based on data from the same publications and patients, yielded a positive EPV of 93% (95% CI 83% to 99%).ConclusionsThe results indicate that FN may play a role in PHC patients with an acute sore throat, but the association is much weaker compared with GAS.

“…Suppurative infection, either local or distant, is a common complication. Local suppurative infection in the form of head and neck abscess, jugular vein thrombophlebitis [ 11 ], peritonsillar abscess [ 12 ] and cervical necrotizing fasciitis [ 13 ], have been described. SAG bacteremia in the absence of any apparent infection has also been reported [ 14 ].…”

Rapidly progressive necrotizing pneumonia: remember the Streptococcus anginosus group!

Acute necrotizing pneumonia in an immunocompetent host is uncommon and usually caused by Staphylococcus aureus infection. Streptococcus anginosus group (SAG) is a less recognized cause of rapidly destructive lung infection resulting in significant patient morbidity and mortality. Unlike many other bacterial infections, SAG can cross fascial planes and cause fulminant infections. Necrotizing pneumonia and lung abscesses due to SAG often fails conservative therapy with antimicrobials and requires definitive surgical intervention. Consideration of SAG as a potential etiology might help to institute definitive therapy earlier and prevent complications.

“…was not mentioned. As shown in Table 1 , GGS or GCS has a prevalence of less than 5% [ 8 – 14 ]. Notably, GGS was not detected using the rapid antigen test because of the lack of group A antigen, which is the target of these tests.…”

Parapharyngeal Abscesses Caused by Group G Streptococcus

Deep neck abscess is a life-threatening infection that causes laryngeal edema and upper airway occlusion. The predominant bacterial species involved in this disorder is group A streptococcus. Group G streptococcus (GGS) constitutes the normal commensal flora of the human upper airway. Although rarely, it can cause pharyngitis, tonsillitis, and peritonsillar abscess. Here, we report a case of a woman with parapharyngeal abscess caused by GGS. A 56-year-old woman presented to the emergency department with complaints of sore throat and cervical swelling, and a diagnosis of parapharyngeal abscess was established. She had upper airway occlusion, requiring urgent tracheostomy. Endoscopic incision and drainage of the abscess using a specially designed, rigid curved laryngoscope was successfully performed. Since a rigid curved laryngoscope creates a wide viewing field and working space, it was useful for incision and drainage of the parapharyngeal abscess.

Renewal of peritonsillar abscess: Impact of the bacterial species of the infection and clinical features of the patient—A prospective comparative aetiological study

Abstract: Bacteria in the Streptococcus anginosus group appear to predict renewal of PTA symptoms, while Streptococcus pyogenes was not found in our patients with symptom renewal. Certain subgroups of patients should be followed more closely.
