Lambl's excrescences are filiform structures attached to the edges of cardiac valves and have been associated with stroke. Here we report two patients with Lambl's excrescences who developed migraine-like headaches followed by cerebral infarction. Their Lambl's excrescences were first identified by transesophageal echocardiography. One patient was given aspirin and another had surgery for debridement of excrescences. Their outcomes were good. The migraine-like headache might be the first symptom of cerebral ischemia and might be triggered by micro-emboli originated from Lambl's excrescences. Patients with Lambl's excrescences should be closely monitored and surgery should be considered in recurrent stroke cases.

The post cardiac injury syndrome is characterized by the development of a fever, pleuropericarditis, and parenchymal pulmonary infiltrates in the weeks following trauma to the pericardium or myocardium. According to previous reports, almost all cases develop after major cardiac surgery or a myocardial infarction. Recently, a few reports have described post cardiac injury syndrome as a complication of endovascular procedures such as percutaneous cardiac intervention. Here we describe an unusual case of post cardiac injury syndrome after a percutaneous coronary intervention.

Kawasaki disease (KD) is characterized with acute systemic vasculitis, occurs predominantly in children between 6 months to 5 years of age. Patients with this disease recover well and the disease is self-limited in most cases. Since it can lead to devastating cardiovascular complications, KD needs special attention. Recent reports show steady increases in the prevalence of KD in both Japan and Korea. However, specific pathogens have yet to be found. Recent advances in research on KD include searches for genetic susceptibility related to KD and research on immunopathogenesis based on innate and acquired immunity. Also, search for etiopathogenesis and treatment of KD has been actively sought after using animal models. In this paper, the recent progress of research on KD was discussed.

INTRODUCTIONUnexplained syncope is a common condition with a significant impact both on the patient and on healthcare expenditure. Often, the diagnosis is hampered due to the temporary sporadic nature of the symptoms. Conventional monitoring methods have a low yield for identifying an abnormality during a spontaneous event. The implantable loop recorder (ILR), often underutilised, is an important diagnostic device that may fi ll this void in the early assessment of patients presenting with syncope.

MATERIALS AND METHODSThis article begins with 2 case vignettes which highlight the clinical utility of ILRs in making a definitive diagnosis and guiding subsequent management. This is followed by a review of the existing evidence for ILRs, including the recent international guidelines, underpinning the role of ILRs in the present management algorithm of patients presenting with unexplained syncope. The technical aspects and cost implications will also be reviewed.

RESULTSPresent evidence-based international guidelines have recommended the early use of ILRs in the management of patients with unexplained syncope. Furthermore, there may also be an important role for ILR use in patients with presumed epilepsy refractory to treatment and in the neurally mediated syncope cohort with recurrent symptoms. Cost benefit analysis also demonstrates advantages with early ILR use.

CONCLUSIONThe early use of ILR in selected patients remains an accurate, cost-effective, high yield tool for diagnosis and management of patients with unexplained syncope. However, its use should not detract from the importance of taking a detailed medical history and physical examination in the initial assessment to facilitate identification of the aetiology and risk stratification of patients.

OBJECTIVESTo explore the clinical characteristics of cardiac syncope (CS) in children, and understand their significance in predicting the cardiac syncope.

METHODSTwenty-three patients were referred to our department for evaluation of syncope. The diagnosis of the above cases was cardiac syncope. Each patient was interviewed using a standard questionnaire. The clinical histories and standard baseline electrocardiogram were analyzed to identify the variables contributing to the diagnosis of CS in children.

RESULTSA cardiac cause was identified in 23 syncopal patients presenting to the Department of Pediatrics, Peking University First Hospital: sick sinus syndrome in 7, congenital long QT syndrome in 4, third degree atrioventricular block in 2, supraventricular tachycardia in 2, ventricular tachycardia in 1, atrial fibrillation in 1, pacemaker dysfunction in 1, idiopathic pulmonary hypertension in 3, hypertrophic cardiomyopathy in 1, and dilated cardiomyopathy in 1. The average age of CS patients was 9 years. In totally 23 patients, exertion related syncope spells were found in 14 cases (60.9%), syncope spells at various position 7/23 (30.4%), absence of prodromes in 12/23 (52.2%), syncope spells with incontinence in 4/23 (17.4%), history of heart disease in 4/23 (17.4%). Abnormal standard baseline electrocardiogram was found in 21 cases (91.7%).

CONCLUSIONSThe children with cardiac syncope have overt clinical features, especially abnormal findings in electrocardiogram and exertion related syncope spells are the most common clinical features.

Changes in renal function are one of the most common manifestations of severe illness. There is a clinical need to intervene early with proven treatments in patients with potentially deleterious changes in renal function. Unfortunately progress has been hindered by poor definitions of renal dysfunction and a lack of early biomarkers of renal injury. In recent years, the definitional problem has been addressed with the establishment of a new well-defined diagnostic entity, acute kidney injury (AKI), which encompasses the wide spectrum of kidney dysfunction, together with clearer definition and sub-classification of the cardio-renal syndromes. From the laboratory have emerged new biomarkers which allow early detection of AKI, including neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C. This review describes the new concepts of AKI and the cardio-renal syndromes as well as novel biomarkers which allow early detection of AKI. Panels of AKI biomarker tests are likely to revolutionise the diagnosis and management of critically ill patients in the coming years. Earlier diagnosis and intervention should significantly reduce the morbidity and mortality associated with acute kidney damage.
