BACKGROUND: Indigenous populations have high rates of disease and premature mortality. Most Indigenous communities are young, and adolescence (age 10-24 years) provides great opportunities for population health gain. However, the absence of a comprehensive account of Indigenous adolescents' health has been a barrier to effective policy. We aimed to report a national health profile for Indigenous adolescents in Australia. METHODS: We undertook a systematic synthesis of population data to report the health and wellbeing of Indigenous adolescents in Australia...

OBJECTIVE: We aimed to investigate the hypothesis that the presence of left ventricular (LV) dyssynchrony in children with acute rheumatic fever (ARF) children may be a predictor of latent rheumatic carditis. METHODS: Eighty-nine children with ARF and 45 healthy control children were included the study. LV dyssynchrony was investigated by color-coded tissue Doppler imaging. RESULTS: LV dyssynchrony parameters including Ts-SD-12, Ts-12, Ts-SD-6, and Ts-6 were found to be prolonged in children with ARF than in controls (P < ...

Rheumatic heart disease (RHD) occurs due to the accumulation of complications associated with rheumatic fever, and it results in high morbidity and mortality. The majority of cases of RHD are diagnosed in the chronic stages, when treatment options are limited. A small reservoir of cardiac stem cells is responsible for maintaining cardiac homeostasis and repairing tissue damage. Understanding the role of cardiac stem cells and the various proteins responsible for their functions in different pathological stages of RHD is an important area of investigation...

Group A streptococcus (GAS) infection remains a major concern due to multiple diseases including pharyngitis, impetigo, acute rheumatic fever (ARF) and rheumatic heart disease (RHD). It uses different adhesins and virulence factors like Cpa (collagen binding protein) and Scl (collagen-like protein) in its pathogenicity. Scl having similarities with human collagen may contribute to inducing autoimmunity in the host. Here we assessed gene expression, antibody titer of Cpa, Scl1 and Scl2 in both clinical GAS isolates (n=45) and blood (n=45) obtained from pharyngisis, ARF (acute rheumatic fever) and RHD respectively...

Rheumatic heart disease (RHD) is the most serious manifestations of rheumatic fever, which is caused by group A Streptococcus (GAS or Streptococcus pyogenes) infection. RHD is an auto immune sequelae of GAS pharyngitis, rather than the direct bacterial infection of the heart, which leads to chronic heart valve damage. Although antibiotics like penicillin are effective against GAS infection, improper medical care such as poor patient compliance, overcrowding, poverty, and repeated exposure to GAS, leads to acute rheumatic fever and RHD...

Streptococcus pyogenes, the Group A Streptococcus (GAS), is the most common cause of bacterial pharyngitis in children and adults. Innate and adaptive host immune responses are fundamental for defense against streptococcal pharyngitis and are central to the clinical manifestation of disease. Host immune responses also contribute to the severe poststreptococcal immune diseases that constitute the major disease burden for this organism. However, until recently, little was known about the host responses elicited during infection...

Infections due to Streptococcus pyogenes and their complications are a problem of major concern in many countries, including India. Primary prophylaxis with benzathine penicillin is the key to control and prevent sequelae such as acute rheumatic fever and rheumatic heart disease (RF/RHD) or post-streptococcal glomerulonephritis (PSGN). Non-compliance to prophylaxis due to fear of injection and anaphylaxis is major issues in RF/RHD control in India and leads to continued high prevalence of infection and post-streptococcal sequelae...

Indigenous Australians have a much high burden of cardiovascular disease, which occurs at an earlier age than in the non-Indigenous population. Comorbidities such as diabetes are common. Early diagnosis of ischaemic heart disease may be difficult because of barriers such as distance to medical centres, communication problems and family and cultural responsibilities. Disparities in cardiac care between Indigenous and non-Indigenous populations are well documented, with examples including reduced angiography and revascularisation rates in Indigenous patients...

Sarcoidosis is a granulomatous disease that can involve multiple organs including the lungs, eyes, nerves, and skin. Cosmetic tattooing can be a predisposing factor for sarcoidosis, and its incidence is likely to increase along with its popularity. A 47-year-old woman with symptoms of fever and polyarthritis along with erythema nodosum lesions on the legs, swollen eyebrows, and a history of multiple eyebrow tattooing was referred to our center. Since the signs and symptoms were positive for Löfgren's syndrome triad including erythema nodosum, bilateral hilar lymphadenopathy, and polyarthritis, a diagnosis of acute sarcoidosis was made, and treatment was started accordingly...
