Chryseobacterium indologenes is a non-fermentative Gram-negative bacillus that is a rare pathogen in humans. Its occurrence in diabetic children has not been previously reported. In this report, a case is described of C. indologenes bacteraemia possibly associated with the use of a peripheral venous catheter. A 2-year-old boy with type I diabetes mellitus was admitted due to a coma caused by cerebral oedema and was successfully treated for his neurological condition but presented on the tenth day after admission with fever of 40 degrees C, agitation, restlessness, lack of appetite, somnolence and fatigue. His pulse rate was 90 min(-1) and his respiratory rate was 20 min(-1). Laboratory studies revealed a white blood cell count of 4900 mm(-3) with 67% neutrophils and 27% lymphocytes. Two separate blood cultures yielded C. indologenes. Treatment with ceftriaxone was started before the culture results were obtained, and was continued after susceptibility test results were obtained. The patient became afebrile after 48 h, and his general condition improved within 36 h. The infection did not recur. This is believed to be the third case of bacteraemia outside of Asia due to C. indologenes and the first in a diabetic child not otherwise immunocompromised. This case indicates that C. indologenes infection can occur in diabetic children without ventilator or central venous catheter and might be treated with a single agent after in vitro susceptibility tests have been performed.

Islet transplantation (ITx) is an emerging and promising therapy for patients with uncontrolled type 1 diabetes. The islet isolation and purification processes require exposure to extended cold ischemia, warm-enzymatic digestion, mechanical agitation, and use of damaging chemicals for density gradient separation (DG), all of which reduce viable islet yield. In this paper, we describe initial proof-of-concept studies exploring quadrupole magnetic separation (QMS) of islets as an alternative to DG to reduce exposure to these harsh conditions. Three porcine pancreata were split into two parts, the splenic lobe (SPL) and the combined connecting/duodenal lobes (CDL), for paired digestions and purifications. Islets in the SPL were preferentially labeled using magnetic microparticles (MMPs) that lodge within the islet microvasculature when infused into the pancreas and were continuously separated from the exocrine tissue by QMS during the collection phase of the digestion process. Unlabeled islets from the CDL were purified by conventional DG. Islets purified by QMS exhibited significantly improved viability (measured by oxygen consumption rate per DNA, p < 0.03) and better morphology relative to control islets. Islet purification by QMS can reduce the detrimental effects of prolonged exposure to toxic enzymes and density gradient solutions and substantially improve islet viability after isolation.

Background Autoimmune polyglandular syndrome type II (APS II) is defined as the combination of autoimmune adrenal insufficiency and autoimmune thyroid disease (AITD) and/or type I diabetes mellitus (T1DM) in the same patient. Case presentation A 15-year-old boy had a history of weight loss, nausea and vomiting, headache, restlessness, and tanned skin. He was diagnosed with Graves' disease. Two weeks after carbimazol therapy was commenced, he presented with adrenal crises (fever, arterial hypotension, hyponatremia, adrenocorticotropic hormone [ACTH] 1119.6 ng/mL [normal range <60] and low cortisol). He received hydrocortisone and fludrocortisone, and improved quickly. Thyroid-stimulating hormone (TSH) receptor autoantibodies as well as 21-hydroxylase antibodies were elevated. Conclusions Although the combination of Graves' and Addison's disease is extremely rare, especially in children, it is critical to make the diagnosis. Accelerated metabolic rate increased the risk for adrenal crises in our patient. This case contributes to the spectrum of APS II and its manifestation.
