Pilot use of a mycolactone-specific lateral flow assay for Buruli ulcer: A case report from Japan.

Buruli ulcer, caused by , is a neglected tropical disease (NTD) characterized by necrosis of the cutaneous tissue, predominantly affecting the limbs. The pathogenesis of this disease is mainly attributed to mycolactone, a lipid toxin produced by . Here, we report the case of a 7-year-old Japanese girl who presented with worsening ulceration on her left forearm, extending to the elbow, following antimicrobial treatment.

Actual incidence of severe neonatal hypoglycemia in non-risk term neonates: A 10 year survey of all cases in Toyama Prefecture, Japan.

Background: Severe neonatal hypoglycemia may cause irreversible neurological sequelae. Although blood glucose (BG) screening in term neonates without risk factors for hypoglycemia (non-risk neonates) is not recommended in the current guidelines, severe hypoglycemia can occur in such neonates. To evaluate the necessity of BG screening in non-risk neonates, it is important to determine the accurate incidence of severe hypoglycemia in those neonates.

Clinical significance of serum soluble TNF receptor II level and soluble TNF receptor II/I ratio as indicators of coronary artery lesion development in Kawasaki disease.

To investigate the clinical significance of serum soluble tumor necrosis factor receptor (sTNFR) II level and sTNFR II/I ratio as indicators of the development of coronary artery lesions (CALs) in Kawasaki disease (KD), we measured levels of serum sTNFR I and II, interleukin (IL)-6, IL-18, and neopterin in 63 patients with KD, including nine patients with CALs and 20 healthy controls. At the time of diagnosis of KD before intravenous immunoglobulin (IVIG) treatment, serum sTNFR I and II levels were found to be significantly higher in non-responders to IVIG treatment than in responders. On the contrary, serum sTNFR II levels and sTNFR II/I ratio were significantly higher in patients with KD having CALs than in those without CALs.

Serum tau protein as a marker of disease activity in enterohemorrhagic Escherichia coli O111-induced hemolytic uremic syndrome.

Tau protein levels in cerebrospinal fluid (CSF) and serum are elevated in patients with various central nervous system diseases. We investigated whether serum tau protein levels are useful for predicting and assessing disease activity of acute encephalopathy (AE) in enterohemorrhagic Escherichia coli (EHEC) O111-induced hemolytic uremic syndrome (HUS; EHEC encephalopathy). Serum samples were obtained from 14 patients with EHEC O111/HUS, 20 patients with non-EHEC-related AE, and 20 age- and sex-matched healthy controls.

Extensive serum biomarker analysis in patients with enterohemorrhagic Escherichia coli O111-induced hemolytic-uremic syndrome.

Proinflammatory cytokines are related to the pathogenesis of enterohemorrhagic Escherichia coli infection and hemolytic-uremic syndrome (HUS). We employed an antibody array that simultaneously detects 174 serum cytokines. We identified five serum biomarkers, namely insulin growth factor-binding protein-2, angiopoietin-2, soluble interleukin-6 receptor, soluble tumor necrosis factor receptor type II, and matrix metalloprotease protein-3 whose levels increased with the development of HUS.

Cytokine profiles of patients with enterohemorrhagic Escherichia coli O111-induced hemolytic-uremic syndrome.

Proinflammatory cytokines are related to the pathogenesis of enterohemorrhagic Escherichia coli (EHEC) infection and hemolytic-uremic syndrome (HUS). We assessed the kinetics of the release of cytokines such as neopterin, interleukin (IL)-6, IL-8 and tumour necrosis factor (TNF)-α and the soluble forms of type I and II TNF receptors during EHEC O111-induced HUS (EHEC O111/HUS). Fourteen patients with EHEC O111/HUS were enrolled in this study.

Encephalopathy, disseminated intravascular coagulation, and hemolytic-uremic syndrome after infection with enterohemorrhagic Escherichia coli O111.

An outbreak of enterohemorrhagic Escherichia coli (EHEC) occurred in Toyama and other prefectures in Japan during 2011. Some patients, including adults, showed complications such as encephalopathy, disseminated intravascular coagulation, and hemolytic-uremic syndrome, and the disease course was extremely aggressive. This report describes the clinical features of four patients infected with Escherichia coli (E.
