Hyperimmunoglobulinemia D syndrome (HIDS) is an autoinflammatory disorder that is caused by mevalonate kinase deficiency (MKD). Recent advances in the pathogenesis of MKD, including the proposed mechanisms of inflammasome activation, provide the basis for the development of new treatment modalities. So far, feedback on the treatment of HIDS with biological medicines has come from case reports with limited numbers of patients. In this review, we summarize the data that is currently available on the treatment of HIDS in children, with the emphasis on new therapies, and present three Finnish pediatric cases treated with anakinra. Case reports have been published on 33 pediatric HIDS patients who have been treated with biological medicines, and in some cases, they were treated with more than one drug. Of these patients, 21 were treated with anakinra and 16 with etanercept, resulting in complete or partial responses in 90 and 50 % of cases, respectively. A further five patients were treated with canakinumab, with complete or partial responses. Conclusion: The accumulating evidence on the efficacy and safety of biological drugs in pediatric HIDS suggests that the anti-interleukin-1 agent anakinra is the drug of choice for HIDS in children. © 2015, Springer-Verlag Berlin Heidelberg.

Background-: It is unknown whether the preferred 1-stent bifurcation stenting approach with stenting of the main vessel (MV) and optional side branch stenting using drug-eluting stents should be finalized by a kissing balloon dilatation (FKBD). Therefore, we compared strategies of MV stenting with and without FKBD. Methods and results-: We randomized 477 patients with a bifurcation lesion to FKBD (n≤238) or no FKBD (n≤239) after MV stenting. The primary end point was major adverse cardiac events: cardiac death, non-procedure-related index lesion myocardial infarction, target lesion revascularization, or stent thrombosis within 6 months. The 6-month major adverse cardiac event rates were 2.1% and 2.5% (P≤1.00) in the FKBD and no-FKBD groups, respectively. Procedure and fluoroscopy times were longer and more contrast media was needed in the FKBD group than in the no-FKBD group. Three hundred twenty-six patients had a quantitative coronary assessment. At 8 months, the rate of binary (re)stenosis in the entire bifurcation lesion (MV and side branch) was 11.0% versus 17.3% (P≤0.11), in the MV was 3.1% versus 2.5% (P≤0.68), and in the side branch was 7.9% versus 15.4% (P≤0.039) in the FKBD versus no-FKBD groups, respectively. In patients with true bifurcation lesions, the side branch restenosis rate was 7.6% versus 20.0% (P≤0.024) in the FKBD and no-FKBD groups, respectively. Conclusions-: MV stenting strategies with and without FKBD were associated with similar clinical outcomes. FKBD reduced angiographic side branch (re)stenosis, especially in patients with true bifurcation lesions. The simple no-FKBD procedures resulted in reduced use of contrast media and shorter procedure and fluoroscopy times. Long-term data on stent thrombosis are needed.

Traumatic brain injury (TBI) can cause a myriad of sequelae depending on its type, severity, and location of injured structures. These can include mood disorders, posttraumatic stress disorder and other anxiety disorders, personality disorders, aggressive disorders, cognitive changes, chronic pain, sleep problems, motor or sensory impairments, endocrine dysfunction, gastrointestinal disturbances, increased risk of infections, pulmonary disturbances, parkinsonism, posttraumatic epilepsy, or their combinations. The progression of individual pathologies leading to a given phenotype is variable, and some progress for months. Consequently, the different post-TBI phenotypes appear within different time windows. In parallel with morbidogenesis, spontaneous recovery occurs both in experimental models and in human TBI. A great challenge remains; how can we dissect the specific mechanisms that lead to the different endophenotypes, such as posttraumatic epileptogenesis, in order to identify treatment approaches that would not compromise recovery?This article is part of a Special Issue entitled "NEWroscience 2013". © 2014 Elsevier Inc.

OBJECTIVE: We describe the epidemiological and microbiological process in the clearing of a foodborne outbreak of Yersinia pseudotuberculosis O:1 linked to raw carrots and frequency of the associated reactive extra-gastrointestinal manifestations.METHODS: The patient samples were investigated by routine culture or antibody testing methods. The real-time bacterial PCR was used to detect Y pseudotuberculosis in samples from the grated carrots and in those taken from the carrot storage. Genotype of bacterial isolates was determined by pulsed-field gel electrophoresis. For case identification, we retrospectively looked over the laboratory files of the central hospital focusing on the time period of the outbreak.RESULTS: Altogether 49 case patients were identified. Y pseudotuberculosis was detected by real-time PCR analysis in samples taken from grated carrots and from the carrot distributor. Bacterial isolates originating from the farm environment showed identical serotype (O:1) and genotype (S12) with the patients' isolates. Among 37 adults, reactive arthritis (ReA) was found in 8 (22%) and three adults had probable ReA. Six (67%) out of nine human leucocyte antigen (HLA) typed patients with ReA were HLA-B27 positive. Erythema nodosum was found in 42% of the 12 children, whereas none of them had definite ReA.CONCLUSIONS: In this outbreak, Y pseudotuberculosis was for the first time detected in both patient and food samples. ReA was more common than earlier reported in the outbreaks associated with this pathogen; the reason may be that the previous outbreaks have occurred among children. HLA-B27 frequency was higher than usually reported in single-source outbreaks of ReA. Published by the BMJ Publishing Group Limited.

Inflammatory Bowel Diseases | Year: 2011

Background: The present study aimed to characterize the incidence of pediatric inflammatory bowel disease (IBD) in Finland and determine its temporal trends. Methods: The patients' data were based on the database of the Social Insurance Institution. New cases diagnosed with IBD at the age <18 years in Finland between years 1987-2003 were included. Annual incidence rates were calculated per 100,000 pediatric populations (with 95% confidence intervals [CI]). The country is divided into 21 hospital districts and regional differences were evaluated accordingly. Results: The incidence of pediatric IBD increased from 5 per 100,000 in 1987 to 15 per 100,000 in 2003. The average rate of increase was 6.5% per year (95% CI 5.4%-7.5%). The trends were comparable for boys and girls, also by age group. Information on disease subtype was available from 1992 and during this 12-year period the incidence of Crohn's disease (CD) increased from 2-5 per 100,000 and that of ulcerative colitis (UC) from 4-9 per 100,000. Conclusions: Our results demonstrate a very high incidence rate for childhood IBD and in particular UC in Finland. Furthermore, a rapid increase took place nationwide in the incidence of both CD and UC during the past two decades. Copyright © 2010 Crohn's & Colitis Foundation of America, Inc.
