Review
Excessive activation of immune cells by environmental factors, such as infection or individual genetic risk, causes various autoimmune diseases. species are gram-positive bacteria that colonize the nasopharynx, respiratory tract, gastrointestinal tract, genitourinary tract, and skin. Group A (GAS) species cause various symptoms, ranging from mild infections, such as tonsillitis and pharyngitis, to serious infections, such as necrotizing fasciitis and streptococcal toxic shock syndrome. The contribution of GAS infections to several autoimmune diseases, including acute rheumatic fever, vasculitis, and neuropsychiatric disorders, has been studied. In this review, we focus on the association between streptococcal infections and autoimmune diseases, and discuss current research on the mechanisms underlying the initiation and progression of autoimmune diseases.

Reactive arthritis is an extremely rare spondyloarthritis that affects the peripheral joints and spine, resulting in common symptoms such as arthritis, urethritis, conjunctivitis, and mucocutaneous lesions. On rare occasions, oral lesions such as circinate erosions on the hard and soft palate, gums, tongue, and cheeks may occur. Reactive arthritis may develop during or after genitourinary or gastrointestinal bacterial infections such as Shigella, Salmonella, Yersinia, and Chlamydia. A 36-year-old man presented with circinate balanitis, urethral discharge, oligoarthralgia, conjunctivitis, lymphadenopathy, pharyngitis, and erythematous lesions on the palate. Culture examination showed presence of Neisseria gonorrhoeae and antibiotic treatment resulted in improvement of conjunctivitis and the lesions on the penis. However, severe oligoarthralgia, palatal erosions that increased in severity and size, and depilated areas on the tongue were observed. The definitive diagnosis was reactive arthritis. The prevalence of sexually transmitted infections is increasing, highlighting the need to increase awareness of associated risks such as reactive arthritis. Moreover, consideration of non-specific oral manifestations in a systemic context may aid in effective diagnosis and treatment, suggesting the need for multidisciplinary teams.

BACKGROUND
Acute epiglottitis in adults is a rare, potentially life-threatening condition caused by a bacterial infection in the epiglottis. Typical symptoms are fever, sore throat, and respiratory distress caused by upper airway obstruction. Proper treatment is needed for a good outcome.
CASE PRESENTATION
We here present a 54-year-old female patient with acute epiglottitis. Her airway was secured by endotracheal intubation and she received antimicrobial therapy. She developed an abscess around the epiglottis that needed surgical drainage and tracheotomy. However, she fully recovered after nine days in hospital.
INTERPRETATION
Acute epiglottitis in adults is a potentially life-threatening condition. The prognosis is good with proper treatment including selective airway intervention, antimicrobial therapy, and close monitoring.

Comparative Study Randomized Controlled Trial
Penicillin V four times daily for five days versus three times daily for 10 days in patients with pharyngotonsillitis caused by group A streptococci: randomised controlled, open label, non-inferiority study.
OBJECTIVE
To determine whether total exposure to penicillin V can be reduced while maintaining adequate clinical efficacy when treating pharyngotonsillitis caused by group A streptococci.
DESIGN
Open label, randomised controlled non-inferiority study.
SETTING
17 primary healthcare centres in Sweden between September 2015 and February 2018.
PARTICIPANTS
Patients aged 6 years and over with pharyngotonsillitis caused by group A streptococci and three or four Centor criteria (fever ≥38.5°C, tender lymph nodes, coatings of the tonsils, and absence of cough).
INTERVENTIONS
Penicillin V 800 mg four times daily for five days (total 16 g) compared with the current recommended dose of 1000 mg three times daily for 10 days (total 30 g).
MAIN OUTCOME MEASURES
Primary outcome was clinical cure five to seven days after the end of antibiotic treatment. The non-inferiority margin was prespecified to 10 percentage points. Secondary outcomes were bacteriological eradication, time to relief of symptoms, frequency of relapses, complications and new tonsillitis, and patterns of adverse events.
RESULTS
Patients (n=433) were randomly allocated to the five day (n=215) or 10 day (n=218) regimen. Clinical cure in the per protocol population was 89.6% (n=181/202) in the five day group and 93.3% (n=182/195) in the 10 day group (95% confidence interval -9.7 to 2.2). Bacteriological eradication was 80.4% (n=156/194) in the five day group and 90.7% (n=165/182) in the 10 day group. Eight and seven patients had relapses, no patients and four patients had complications, and six and 13 patients had new tonsillitis in the five day and 10 day groups, respectively. Time to relief of symptoms was shorter in the five day group. Adverse events were mainly diarrhoea, nausea, and vulvovaginal disorders; the 10 day group had higher incidence and longer duration of adverse events.
CONCLUSIONS
Penicillin V four times daily for five days was non-inferior in clinical outcome to penicillin V three times daily for 10 days in patients with pharyngotonsillitis caused by group A streptococci. The number of relapses and complications did not differ between the two intervention groups. Five day treatment with penicillin V four times daily might be an alternative to the currently recommended 10 day regimen.

Randomized Controlled Trial
BACKGROUND
Tonsillectomy is regularly performed in adults with acute tonsillitis, but with scarce evidence. A reduction in tonsillectomies has coincided with an increase in acute adult hospitalisation for tonsillitis complications. We aimed to assess the clinical effectiveness and cost-effectiveness of conservative management versus tonsillectomy in patients with recurrent acute tonsillitis.
METHODS
This pragmatic multicentre, open-label, randomised controlled trial was conducted in 27 hospitals in the UK. Participants were adults aged 16 years or older who were newly referred to secondary care otolaryngology clinics with recurrent acute tonsillitis. Patients were randomly assigned (1:1) to receive tonsillectomy or conservative management using random permuted blocks of variable length. Stratification by recruiting centre and baseline symptom severity was assessed using the Tonsil Outcome Inventory-14 score (categories defined as mild 0-35, moderate 36-48, or severe 49-70). Participants in the tonsillectomy group received elective surgery to dissect the palatine tonsils within 8 weeks after random assignment and those in the conservative management group received standard non-surgical care during 24 months. The primary outcome was the number of sore throat days collected during 24 months after random assignment, reported once per week with a text message. The primary analysis was done in the intention-to-treat (ITT) population. This study is registered with the ISRCTN registry, 55284102.
FINDINGS
Between May 11, 2015, and April 30, 2018, 4165 participants with recurrent acute tonsillitis were assessed for eligibility and 3712 were excluded. 453 eligible participants were randomly assigned (233 in the immediate tonsillectomy group vs 220 in the conservative management group). 429 (95%) patients were included in the primary ITT analysis (224 vs 205). The median age of participants was 23 years (IQR 19-30), with 355 (78%) females and 97 (21%) males. Most participants were White (407 [90%]). Participants in the immediate tonsillectomy group had fewer days of sore throat during 24 months than those in the conservative management group (median 23 days [IQR 11-46] vs 30 days [14-65]). After adjustment for site and baseline severity, the incident rate ratio of total sore throat days in the immediate tonsillectomy group (n=224) compared with the conservative management group (n=205) was 0·53 (95% CI 0·43 to 0·65; <0·0001). 191 adverse events in 90 (39%) of 231 participants were deemed related to tonsillectomy. The most common adverse event was bleeding (54 events in 44 [19%] participants). No deaths occurred during the study.
INTERPRETATION
Compared with conservative management, immediate tonsillectomy is clinically effective and cost-effective in adults with recurrent acute tonsillitis.

Meta-Analysis
BACKGROUND
In surgical patients undergoing general anaesthesia, coughing at the time of extubation is common and can result in potentially dangerous complications. We performed a systematic review and meta-analysis to assess the efficacy and safety of i.v. lidocaine administration during the perioperative period to prevent cough and other airway complications.
METHODS
We searched Medical Literature Analysis and Retrieval System, Excerpta Medica database, and Cochrane Central Register of Controlled Trials for RCTs comparing the perioperative use of i.v. lidocaine with a control group in adult patients undergoing surgery under general anaesthesia. The RCTs were assessed using risk-of-bias assessment, and the quality of evidence was assessed using Grading of Recommendations, Assessment, Development and Evaluations (GRADE).
RESULTS
In 16 trials (n=1516), the administration of i.v. lidocaine compared with placebo or no treatment led to large reductions in post-extubation cough (risk ratio [RR]: 0.64; 95% confidence interval [CI]: 0.48-0.86) and in postoperative sore throat at 1 h (RR: 0.46; 95% CI: 0.32-0.67). There was no difference in incidence of laryngospasm (risk difference [RD]: 0.02; 95% CI: -0.07 to 0.03) or incidence of adverse events related to the use of lidocaine.
CONCLUSIONS
The use of i.v. lidocaine perioperatively decreased airway complications, including coughing and sore throat. There was no associated increased risk of harm.

Review
BACKGROUND
The vast majority of patients with peritonsillar abscess (PTA) recover uneventfully on abscess drainage and antibiotic therapy. However, occasionally patient´s condition deteriorates as the infection spread in the upper airway mucosa, through cervical tissues, or hematogenously. The bacterial etiology of PTA is unclarified and the preferred antimicrobial regimen remains controversial. The current narrative review was carried out with an aim to (1) describe the spectrum of complications previously recognized in patients with peritonsillar abscess (PTA), (2) describe the bacterial findings in PTA-associated complications, and (3) describe the time relation between PTA and complications.
METHODS
Systematic searches in the Medline and EMBASE databases were conducted and data on cases with PTA and one or more complications were elicited.
RESULTS
Seventeen different complications of PTA were reported. The most frequently described complications were descending mediastinitis (n = 113), para- and retropharyngeal abscess (n = 96), necrotizing fasciitis (n = 38), and Lemierre´s syndrome (n = 35). Males constituted 70% of cases and 49% of patients were > 40 years of age. The overall mortality rate was 10%. The most prevalent bacteria were viridans group streptococci (n = 41, 25%), beta-hemolytic streptococci (n = 32, 20%), F. necrophorum (n = 21, 13%), S. aureus (n = 18, 11%), Prevotella species (n = 17, 10%), and Bacteroides species (n = 14, 9%). Simultaneous diagnosis of PTA and complication was more common (59%) than development of complication after PTA treatment (36%) or recognition of complication prior to PTA (6%).
CONCLUSION
Clinicians involved in the management of PTA patients should be aware of the wide range of complications, which may arise in association with PTA development. Especially males and patients > 40 years of age seem to be at an increased risk of complicated disease. In addition to Group A streptococci and F. necrophorum, the current findings suggest that viridans group streptococci, S. aureus, Prevotella, and Bacteroides may also play occasional roles in the development of PTA as well as spread of infection. Complications occasionally develop in PTA patients, who are treated with antibiotics and surgical drainage.

Review
BACKGROUND
-associated autoinflammatory disease (-AID) is an autosomal dominant autoinflammatory disorder caused by variants of gene. We aimed to report a cohort of Chinese adult patients with -AID and summarised phenotypes and genotypes.
METHODS
Twenty patients were diagnosed with -AID after performing whole-exome sequencing and were included in our cohort. Demographic information, clinical data and treatment response were collected and evaluated. A literature review of -AID was performed, and the clinical features and mutated sites were summarised and compared with our cohort.
RESULTS
Among the 20 -AID patients, the main clinical features of -AID included fever, cutaneous rash, arthralgia/arthritis, pharyngitis/tonsillitis, lymphadenopathy, myalgia and abdominal pain/diarrhoea. Thirteen variants were detected as F402L, G39V, R1030X, R7G, E24A, Q90X, A218V, A259V, W581X, G729R, R859W, c.-150T>C and c.*126G>C. Glucocorticoids were used in 14 patients, immunosuppressive agents in 13, and tocilizumab in 2. Seventeen patients had good responses to therapy. When compared with 50 -AID patients from other countries, Chinese patients had fewer variants in exon 3, higher incidences of cutaneous rash, pharyngitis/tonsillitis and lymphadenopathy. Among all these 70 -AID patients, patients carrying non-exon-3 variants had higher frequencies of ocular involvement, pharyngitis/tonsillitis, headache and lymphadenopathy than those with exon-3 variants.
CONCLUSION
This is the largest cohort of -AID in the world and seven novel variants of were identified. Chinese adult patients of -AID had more non-specific symptoms such as pharyngitis/tonsillitis and lymphadenopathy when compared with patients from other countries, for which the less occurrence of exon-3 variants might be one possible reason.
