A paediatric hospital care AMC report for Northern Ireland.

Background: Antimicrobial stewardship (AMS) is high on the agenda of healthcare policymakers and measurement of its impact is reliant on antimicrobial consumption (AMC) and antimicrobial resistance (AMR) data. Recent AMC reports have identified high antimicrobial prescribing rates in Northern Ireland (NI), compared with UK and European countries, but no separate paediatric data were reported.

Objectives: To describe AMC trends in paediatric and neonatal inpatient care in NI between September 2015 and September 2020, in order to: (i) create a paediatric-specific AMC report and benchmark for future AMS interventions; and (ii) develop an action plan for establishing paediatric AMC/AMR surveillance in NI.

How to interpret a paediatric blood culture.

Blood culture is one of the most important diagnostic tests in medicine, considering the significant morbidity and mortality associated with bloodstream infection (BSI). However, it is an often misused and misinterpreted test in everyday paediatric practice. In this article, we explore the evidence related to paediatric blood cultures, with the aim of providing clear and clinically-relevant recommendations for its judicious use.

PRDX3 is associated with metastasis and poor survival in uveal melanoma.

Aims: Uveal melanoma (UM) is the most common primary intraocular malignancy in adults, and 40% develop fatal metastatic disease. Overexpression of thioredoxin-dependent peroxidase reductase (PRDX3) has been implicated in several cancers, including prostate, breast, colorectal and lung cancer. The aim of this study was to compare the immunohistochemical expression of PRDX3 in formalin-fixed, paraffin-embedded (FFPE) primary UM tissues of patients who did and did not develop metastatic disease.

Emergency department attendance following 4-component meningococcal B vaccination in infants.

Introduction: In September 2015, the UK became the first country in the world to introduce the 4-component meningococcal B vaccine(4CMenB) into the routine vaccine schedule for infants. 4CMenB is known to cause fever in infants. Infants presenting with fever, particularly those under 3 months, have a significant risk of serious bacterial infection(SBI).

Rhabdomyolysis Complicating Typhoid Fever in A Child and Review of the Literature.

Typhoid fever is an important cause of morbidity and mortality in the developing world, particularly in children, but is infrequently observed in the developed world and can occur in patients without a significant travel history. Rhabdomyolysis as a complication has rarely been reported, and never in a child. A child with Salmonella enterica serovar Typhi septicemia, complicated by rhabdomyolysis, encephalopathy and pancreatitis is described and all 15 reported cases to date are summarized.

Australia-wide Point Prevalence Survey of Antimicrobial Prescribing in Neonatal Units: How Much and How Good?

Background: There is increasing recognition of the threat to neonatal patients from antibiotic resistance. There are limited data on antimicrobial prescribing practices for hospitalized neonates. We aimed to describe antimicrobial use in hospitalized Australian neonatal patients, and to determine its appropriateness.

Australia-wide point prevalence survey of the use and appropriateness of antimicrobial prescribing for children in hospital.

Objectives: To describe antimicrobial use in hospitalised Australian children and to analyse the appropriateness of this antimicrobial use.

Design: Multicentre single-day hospital-wide point prevalence survey, conducted in conjunction with the Antimicrobial Resistance and Prescribing in European Children study.

Setting: Eight children's hospitals across five Australian states, surveyed during late spring and early summer 2012.

Increasing pyomyositis presentations among children in Queensland, Australia.

Background: Pyomyositis, usually associated with tropical climates, occurs less commonly in temperate regions and is most often caused by Staphylococcus aureus. Several community-acquired methicillin-resistant S. aureus (CA-MRSA) clones have emerged in Queensland since the beginning of the century, and they now account for a significant proportion of invasive staphylococcal infection.

Balamuthia mandrillaris Encephalitis: Survival of a Child With Severe Meningoencephalitis and Review of the Literature.

Balamuthia mandrillaris causes granulomatous amoebic encephalitis, which is frequently fatal. There are few reports of survival in children. A 4-year-old child developed severe meningoencephalitis with multiple intracranial ring-enhancing lesions.

Proteomics in uveal melanoma.

Uveal melanoma is the most common primary intraocular malignancy in adults, with an incidence of 5-7 per million per year. It is associated with the development of metastasis in about 50% of cases, and 40% of patients with uveal melanoma die of metastatic disease despite successful treatment of the primary tumour. The survival rates at 5, 10 and 15 years are 65%, 50% and 45% respectively.

Effects of prostaglandin F(2α) on adipocyte biology relevant to graves' orbitopathy.

Background: In Graves' orbitopathy (GO), increased proliferation, excess adipogenesis, and hyaluronan overproduction produce GO exophthalmos. Enophthalmos occurs in some glaucoma patients treated with Bimatoprost (prostaglandin F2α, PGF2α) eye drops. We hypothesized that enophthalmos is secondary to reductions in orbital tissue proliferation, adipogenesis, and/or increased lipolysis.

Differential expression of fourteen proteins between uveal melanoma from patients who subsequently developed distant metastases versus those who did Not.

Purpose: To compare the proteomic profiles of two categories of primary uveal melanoma tissue samples; those from patients who have subsequently developed metastatic disease and those who have not.

Methods: Two-dimensional difference gel electrophoresis (2D DIGE) was performed on 25 uveal melanoma tissue specimens (minimum follow-up of 7 years) comparing nine uveal melanoma tumors from patients who developed metastatic disease and 16 from those who did not. Most of the tumors which metastasized also exhibited chromosome 3 monosomy.

Beware the empty curette!

Background And Objective: Chalazions are a common occurrence in the eyelids due to chronic inflammation in the tarsal plate. Treatment of non-resolving cases may involve incision and curettage. Chalazions that are recurrent should arouse suspicion.
