Fusobacterium necrophorum (Fn), a gram-negative anaerobe, is increasingly implicated as an etiologic agent in older adolescents and young adults with sore throat. Inadequately treated Fn pharyngitis may result in suppurative complications such as peritonsillar abscess and Lemierre's syndrome. Data from the literature suggest that the incidence of life-threating complications in these age groups from Fn pharyngitis (Lemierre's syndrome) in the United States exceeds those associated with group A beta-hemolytic streptococcal (GAS) pharyngitis (acute rheumatic fever)...

A 12-year-old Dutch boy came to the paediatrician with involuntary movements of the right half of his body. He was diagnosed with Sydenham chorea as a consequence of acute rheumatic fever. Acute rheumatic fever is a rare disease in Western countries and should be recognised in time. Antibiotic prophylaxis is indicated in patients who have had acute rheumatic fever, at least until the age of 40.

OBJECTIVES: Familial Mediterranean fever (FMF) is characterized by recurrent, self-limited attacks of fever with serositis involving the peritoneum, pleura and joints. Fatigue is a common problem in many pediatric rheumatic diseases; however, has not been evaluated systematically in FMF patients. Accordingly, the aim of this study was to evaluate fatigue and its possible allied factors in patients with FMF. METHODS: Patients with FMF, aged between 10-18 years, were assessed by completed validated fatigue questionnaire (Checklist Individual Strength-20)...

RHD is an inflammatory disease resulting from interactive immune, genetic, and environmental factors. Various, epidemiological studies have shown the association of genetic variants of cytokine genes with a predisposition to RHD. However, the results from different populations are inconsistent. Therefore, we carried out a meta- analysis of twenty-three published case-control studies and the results indicated that TGF-β1 +869 T/C (T vs. C: OR = 7.68, 95% CI = 1.62-36.50; TT + CT vs. CC OR = 1...

Aboriginal children in northern Australia have high rates of rheumatic fever and rheumatic heart disease, which are chronic conditions because of the need for long-term treatment and monitoring. This article critically reviews the literature on transition to adult care for children with chronic conditions and considers applicability to the care of these children. The review was merged with findings from a focussed ethnography conducted in four remote Aboriginal communities with young people who have these conditions...

The Seventh World Congress of Pediatric Cardiology was held in Barcelona in July, 2017. The central philosophy of the congress was "bridging together" all major specialties in the field. This article summarises the highlights of the meeting as it relates to ambulatory paediatric cardiology. There is a now a more unified approach to children with CHD, including assessment of neuro-developmental outcomes. The new World Heart Foundation criteria for the diagnosis of rheumatic fever remain controversial.

It is often a challenge and a dilemma for clinicians encountering patients with pyrexia of unknown origin. Numerous tests performed to determine the underlying cause often give inconclusive results. We present a 52-year-old man with undulating fever for more than 10 months with persistent hyperferritinaemia, and negative immunological and serological markers. Despite corticosteroids, disease modifying anti-rheumatic agents and immune-modulator therapy, he succumbed to the illness. A diagnosis of refractory Adult onset Still's disease complicated by haemophagocytic lymphohistiocytosis was made...

In clinical practice and literature studies, the most common condition associated to streptococcal tonsillitis used to be acute rheumatic fever (ARF). Several publications in the late years report a more frequent and distinctive entity from ARF following β-hemolytic group A streptococcus infection in patients with post-infectious arthritis, that do not fulfill the modified Jones criteria, the so-called post-streptococcal reactive arthritis (PSRA). A distinctive pattern of clinical framing and biological profile in patients with PSRA following streptococcal tonsillitis is described, with a non-migratory, additive, recent onset (7-10 days) arthritis that affects small and large joints as well, with a bimodal peak of incidence at 8-14 and 21-37 years of age, with variate response to non-steroidal anti-inflammatory drugs and has a tendency for recurrence and persistence...

Acute rheumatic fever and rheumatic heart disease (ARF/RHD) have long been described as autoimmune sequelae of Streptococcus pyogenes or group A streptococcal (GAS) infection. Both antibody and T-cell responses against immunodominant GAS virulence factors including M-protein, cross-react with host tissue proteins triggering an inflammatory response leading to permanent heart damage. However, in some ARF/RHD endemic regions, throat carriage of GAS is low. As Streptococcus dysgalactiae subspecies equisimilis (SDSE), also known as β-hemolytic groups C and G streptococci (GCS/GGS) also express M-protein, we postulated that streptococci other than GAS may have the potential to initiate or exacerbate ARF/RHD...

Benzathine Penicillin G (BPG) is commonly used for treatment of penicillin-susceptible infections and secondary prevention of rheumatic fever. Death following administration of BPG is extremely rare-only a handful of cases have been described in the literature since the 1950's. In this case series from Israel and Switzerland, we describe nine cases of serious adverse reactions-six fatal reactions and three near-fatalities-occurring within minutes of receiving intramuscular BPG. Allergic reactions or faulty administration were not implicated in any of the cases; however, all patients had cardiac risk factors...

Acute rheumatic fever (ARF) continues to produce a significant burden of disease in New Zealand (NZ) Māori and Pacific peoples. Serious limitations in national surveillance data mean that accurate case totals cannot be generated. Given the changing epidemiology of ARF in NZ and the major national rheumatic fever prevention programme (2012-2017), we updated our previous likely true case number estimates using capture-recapture analyses. Aims were to estimate the likely true incidence of ARF in NZ and comment on the changing ability to detect cases...

BACKGROUND: The aim of this study was to examine the effectiveness of the oral probiotic S. salivarius K12 (K12) in preventing Group A streptococcus (GAS) pharyngitis in 5-14 year old children at high risk of acute rheumatic fever (ARF). New Zealand has high rates of ARF amongst Māori and Pacific children. Children were already enrolled in a school based Ministry of Health throat swabbing and treatment program. Children self-identified and reported sore throats daily and were swabbed twice weekly...

We report an unusual presentation of a large left atrial myxoma in an eight-year-old girl who presented with the sudden onset of chorea. This case illustrates the fact that the presentation of chorea in nonendemic areas for rheumatic fever should raise suspicion for a myxoma. The chorea resolved soon after removal of the myxoma, supporting the hypothesis of an immune-mediated mechanism, or manifestation of paraneoplastic syndrome secondary to the myxoma.

At the population level, rheumatoid arthritis (RA) is generally viewed as autoimmune in nature with a small subgroup of cases having a palindromic form or systemic autoinflammatory disorder (SAID) phenotype. Herein, we describe resistant cases of classical autoantibody associated RA that had clinical, genetic and therapeutic responses indicative of coexistent autoinflammatory disease. Five patients with clinically overlapping features between RA and SAID including polysynovitis and autoantibody/shared epitope positivity, and who had abrupt severe self-limiting attacks including fevers and serositis, are described...

Devinder Toor, Neha Sharma
Acute rheumatic fever (ARF) is a consequence of pharyngeal infection of group A streptococcal (GAS) infection. Carditis is the most common manifestation of ARF which occurs in 30-45% of the susceptible individuals. Overlooked ARF cases might further progress towards rheumatic heart disease (RHD) in susceptible individuals, which ultimately leads to permanent heart valve damage. Molecular mimicry between streptococcal antigens and human proteins is the most widely accepted theory to describe the pathogenesis of RHD...

OBJECTIVE: To explore young Aboriginal people's and clinicians' experiences of injection pain for the 10 years of penicillin injections children are prescribed to prevent rheumatic fever recurrences. METHODS: Aboriginal children on the penicillin regimen and clinicians were purposively recruited from four remote sites in Australia. Semi-structured interviews and participant observations were conducted. Views were synthesised and thematically analysed. RESULTS: A total of 29 Aboriginal children and 59 clinicians were interviewed...

AIMS: New Zealand (NZ) Māori and Pacific children have high rates of acute rheumatic fever (ARF). Around 150 new cases arise each year. As part of the national ARF prevention programme, funding is available to improve housing. To obtain maximum benefit from interventions, an effective tool is needed for targeting high-risk children. This study aimed to assess the effectiveness of using hospitalisations for identifying children at risk of subsequent ARF. METHODS: Three potentially avoidable hospitalisation (PAH) groups were investigated, including diseases thought to be influenced by housing...

BACKGROUND: Acute rheumatic fever (ARF) rates have declined to near zero in nearly all developed countries. However, in New Zealand rates have not declined since the 1980s. Further, ARF diagnoses in New Zealand are inequitably distributed--occurring almost exclusively in Māori (the indigenous population) and Pacific children--with very low rates in the majority New Zealand European population. With ARF diagnosis, secondary prophylaxis is key to prevent recurrence. The purpose of this study was to identify the perceived enablers and barriers to secondary recurrence prophylaxis following ARF for Māori patients aged 14-21...
