How to facilitate NHS professionals to recognise and use skills gained from global health engagement when back in the UK workforce? A participatory action research project to design, pilot and evaluate a series of online leadership workshops.

Objectives: Leadership knowledge and skills are known to be developed by health professionals during global health experiences overseas. However, volunteers struggle to recognise and use these new skills on return to their workplace. A series of bespoke leadership workshops were designed, delivered and evaluated by leadership experts to help enhance the transferability of leadership skills back to the UK National Health Service.

Multiplex Lateral Flow Assay and the Sample Preparation Method for the Simultaneous Detection of Three Marine Toxins.

A multiplex lateral flow immunoassay (LFA) has been developed to detect the primary marine biotoxin groups: amnesic shellfish poisoning toxins, paralytic shellfish poisoning toxins, and diarrhetic shellfish poisoning toxins. The performance characteristics of the multiplex LFA were evaluated for its suitability as a screening method for the detection of toxins in shellfish. The marine toxin-specific antibodies were class-specific, and there was no cross-reactivity between the three toxin groups.

Progression of Mineral Ion Abnormalities in Patients With Jansen Metaphyseal Chondrodysplasia.

Context: Five different activating PTH/PTH-related peptide (PTHrP) receptor (PTHR1) mutations have been reported as causes of Jansen metaphyseal chondrodysplasia (JMC), a rare disorder characterized by severe growth plate abnormalities and PTH-independent hypercalcemia.

Objectives: Assess the natural history of clinical and laboratory findings in 24 patients with JMC and characterize the disease-causing mutant receptors in vitro.

Patients And Methods: The H223R mutation occurred in 18 patients.

Epigenomic Modifications Mediating Antibody Maturation.

Epigenetic modifications, such as histone modifications, DNA methylation status, and non-coding RNAs (ncRNA), all contribute to antibody maturation during somatic hypermutation (SHM) and class-switch recombination (CSR). Histone modifications alter the chromatin landscape and, together with DNA primary and tertiary structures, they help recruit Activation-Induced Cytidine Deaminase (AID) to the immunoglobulin (Ig) locus. AID is a potent DNA mutator, which catalyzes cytosine-to-uracil deamination on single-stranded DNA to create U:G mismatches.

Tracking the amphibian pathogens Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans using a highly specific monoclonal antibody and lateral-flow technology.

The fungus Batrachochytrium dendrobatidis (Bd) causes chytridiomycosis, a lethal epizootic disease of amphibians. Rapid identification of the pathogen and biosecurity is essential to prevent its spread, but current laboratory-based tests are time-consuming and require specialist equipment. Here, we describe the generation of an IgM monoclonal antibody (mAb), 5C4, specific to Bd as well as the related salamander and newt pathogen Batrachochytrium salamandrivorans (Bsal).

Contribution of murine IgG Fc regions to antibody binding to the capsule of Burkholderia pseudomallei.

Immunoglobulin G3 (IgG3) is the predominant IgG subclass elicited in response to polysaccharide antigens in mice. This specific subclass has been shown to crosslink its fragment crystallizable (Fc) regions following binding to multivalent polysaccharides. Crosslinking leads to increased affinity through avidity, which theoretically should lead to more effective protection against bacteria and yeast displaying capsular polysaccharides on their surface.

Burkholderia pseudomallei Capsular Polysaccharide Recognition by a Monoclonal Antibody Reveals Key Details toward a Biodefense Vaccine and Diagnostics against Melioidosis.

Burkholderia pseudomallei is the bacterium responsible for melioidosis, an infectious disease with high mortality rates. Since melioidosis is a significant public health concern in endemic regions and the organism is currently classified as a potential biothreat agent, the development of effective vaccines and rapid diagnostics is a priority. The capsular polysaccharide (CPS) expressed by B.

Angioplasty for renovascular hypertension in 78 children.

Objectives: To evaluate the outcome of percutaneous transluminal angioplasty (PTA) in children with renovascular hypertension (RVH) treated at a single centre over 29 years.

Methods: A retrospective study of the medical charts of all children with RVH who underwent PTA between 1984 and 2012. The primary outcome measurement was blood pressure (BP) achieved after the procedure.

Development of a prototype lateral flow immunoassay (LFI) for the rapid diagnosis of melioidosis.

Burkholderia pseudomallei is a soil-dwelling bacterium and the causative agent of melioidosis. Isolation of B. pseudomallei from clinical samples is the "gold standard" for the diagnosis of melioidosis; results can take 3-7 days to produce.

Systemic polyarteritis nodosa in the young: a single-center experience over thirty-two years.

Objective: Polyarteritis nodosa (PAN) is a rare disease of childhood. The aims of this study were to describe the clinical features, treatment, and outcome of systemic childhood PAN and to identify predictors of relapse.

Methods: A single-center retrospective medical records review of children with PAN fulfilling the European League Against Rheumatism (EULAR)/Paediatric Rheumatology European Society (PRES)/Paediatric Rheumatology International Trials Organisation (PRINTO) classification criteria who were seen over a 32-year period was performed.

Hypertension with or without adrenal hyperplasia due to different inherited mutations in the potassium channel KCNJ5.

We recently implicated two recurrent somatic mutations in an adrenal potassium channel, KCNJ5, as a cause of aldosterone-producing adrenal adenomas (APAs) and one inherited KCNJ5 mutation in a Mendelian form of early severe hypertension with massive adrenal hyperplasia. The mutations identified all altered the channel selectivity filter, producing increased Na(+) conductance and membrane depolarization, the signal for aldosterone production and proliferation of adrenal glomerulosa cells. We report herein members of four kindreds with early onset primary aldosteronism of unknown cause.

Medium-size-vessel vasculitis.

Medium-size-artery vasculitides do occur in childhood and manifest, in the main, as polyarteritis nodosa (PAN), cutaneous PAN and Kawasaki disease. Of these, PAN is the most serious, with high morbidity and not inconsequential mortality rates. New classification criteria for PAN have been validated that will have value in epidemiological studies and clinical trials.

Results of surgical treatment for renovascular hypertension in children: 30 year single centre experience.

Background: We retrospectively reviewed the medical records of all patients who underwent surgery as part of the treatment of renovascular hypertension (RVH) at our centre between 1979 and 2008. Patients. Thirty-seven children (65% male) with a median age of 7.

Management of high blood pressure in children and adolescents: recommendations of the European Society of Hypertension.

Hypertension in children and adolescents has gained ground in cardiovascular medicine, thanks to the progress made in several areas of pathophysiological and clinical research. These guidelines represent a consensus among specialists involved in the detection and control of high blood pressure in children and adolescents. The guidelines synthesize a considerable amount of scientific data and clinical experience and represent best clinical wisdom upon which physicians, nurses and families should base their decisions.

Mid-aortic syndrome: long-term outcome of 36 children.

The clinical characteristics and outcomes of children with mid-aortic syndrome (MAS) and the effectiveness of different therapeutic approaches in reducing hypertension are still debated. We conducted a single-centre retrospective review of the records of children with MAS over 30 years. Children with angiographic evidence of a narrowed abdominal aorta were included.

Mutational analysis of CLC-5, cofilin and CLC-4 in patients with Dent's disease.

Background/aims: Dent's disease is caused by mutations in the chloride/proton antiporter, CLC-5, or oculo-cerebro-renal-syndrome-of-Lowe (OCRL1) genes.

Methods: Eighteen probands with Dent's disease were investigated for mutations in CLC-5 and two of its interacting proteins, CLC-4 and cofilin. Wild-type and mutant CLC-5s were assessed in kidney cells.

Biologic therapy in primary systemic vasculitis of the young.

Objectives: To describe the biologic treatment regimens and report the efficacy and safety of biologic therapies in a multicentre series of children with primary systemic vasculitis (PSV).

Methods: This was a retrospective descriptive case series of children with PSV treated with biologic therapy between February 2002 and November 2007. Primary retrospective outcome assessment measures were: daily corticosteroid dose; Birmingham Vasculitis Activity Score (BVAS); and adverse events (including infection rate).

Epilepsy, ataxia, sensorineural deafness, tubulopathy, and KCNJ10 mutations.

Background: Five children from two consanguineous families presented with epilepsy beginning in infancy and severe ataxia, moderate sensorineural deafness, and a renal salt-losing tubulopathy with normotensive hypokalemic metabolic alkalosis. We investigated the genetic basis of this autosomal recessive disease, which we call the EAST syndrome (the presence of epilepsy, ataxia, sensorineural deafness, and tubulopathy).

Methods: Whole-genome linkage analysis was performed in the four affected children in one of the families.

Advances in childhood vasculitis.

Purpose Of Review: To provide an update on new developments in paediatric vasculitis.

Recent Findings: New classification criteria for childhood vasculitis have recently been proposed and are currently undergoing validation. Infectious triggers are still implicated in the aetiopathogenesis of Kawasaki disease and Henoch-Schonlein purpura.

Hemolytic uremic syndrome associated with invasive pneumococcal disease: the United kingdom experience.

Objective: To describe the presentation, management, and outcome of 43 cases of pneumococcal-associated hemolytic uremic syndrome (P-HUS). An increased incidence of P-HUS has been noted in the United Kingdom between January 1998 and May 2005.

Study Design: Cases with microangiopathic hemolytic anemia (Hb <10 g/dL with fragmented RBCs), thrombocytopenia (platelet count < 130 x 10(9)/L), acute renal impairment with oliguria and elevated plasma creatinine for age, confirmed or suspected pneumococcal infection and/or T-activation were included.

Predictors of long-term outcome of children with idiopathic focal segmental glomerulosclerosis.

Clinical and histological data of children presenting with steroid-resistant nephrotic syndrome and renal biopsy showing focal and segmental glomerulosclerosis from 1980 with a follow-up of over 10 years were reviewed. There were 66 patients; 38 male and 28 female. Age at onset ranged from 0.

Childhood vasculitis and plasma exchange.

Introduction: A retrospective review of therapeutic plasma exchange (TPE) for vasculitis of any form during the period 1993-2003 was carried out in our unit.

Subjects And Methods: The case histories of 32 children undergoing TPE were analysed to determine short-term outcome. The vasculitides consisted of polyarteritis nodosa (PAN), ANCA-associated vasculitis (AAV) [encompassing Wegener's granulomatosis (WG) and microscopic polyangiitis (MPA)/idiopathic crescentic nephritis (ICN)], Henoch-Schönlein purpura (HSP) and non-classified vasculitis (NCV).

A new international classification of childhood vasculitis.

There has been, for many years, a need for an acceptable classification of childhood vasculitis as well as criteria for classifying specific sub-categories of vasculitic disease affecting the young. Hitherto, there has been, with certain exceptions, much reliance on adult classification systems and criteria that have not proved entirely satisfactory. A recent International Consensus Conference held in Vienna in June 2005 attempted to rectify this state of affairs.
