Objective: To evaluate a decade of reported paediatric opioid poisoning cases in the UK.

Methods: The National Poisons Information Service (NPIS) telephone enquiries database (UK Poisons Information Database) was searched for calls regarding opioid poisoning in children under 18 years from 2012 to 2021. The NPIS online clinical guidance database TOXBASE was searched for accesses relating to opioids for both adults and children.

Purpose: Orbital implant exposures, infections, and extrusions can occur many years following enucleation or evisceration. This study analyzes complication rates following porous orbital implant wrapped with a posterior auricular muscle complex graft (PAMCG).

Methods: This is a retrospective study of patients who underwent orbital implantation following enucleation using this technique between 1992 and 2013.

Article Synopsis
  • This study presents a new technique for placing Crawford bicanalicular stents in children to treat congenital nasolacrimal duct obstruction, which simplifies in-office removal.
  • It evaluated the outcomes of 54 patients aged 5 and under who underwent this procedure between 2004 and 2020, focusing on various metrics like extrusion and recurrence rates.
  • Results indicated a 30.3% extrusion rate and low recurrence (5.4%) and operative room removal rates (3.6%), showing the method's effectiveness compared to other existing techniques.

is an economically important species of root-lesion nematode adversely affecting chickpea () yields globally. Integration of resistant crops in farming systems is recognised as the most effective and sustainable management strategy for plant-parasitic nematodes. However, breeding for resistance in chickpea is limited by the lack of genetic diversity.

Purpose: To compare the recurrence rates after pterygium surgery performed by supervised trainee residents and attending physicians.

Methods: This retrospective study included pterygium surgeries performed by trainee residents and attending physicians in an academic institution in South Texas in the years 2008 to 2019. All residents performed surgeries under direct supervision of an attending physician.

The root-lesion nematode, Pratylenchus thornei, is one of the major plant-parasitic nematode species causing significant yield losses in chickpea (Cicer arietinum). In order to identify the underlying mechanisms of resistance to P. thornei, the transcriptomes of control and inoculated roots of three chickpea genotypes viz.

Root-lesion nematodes ( spp.) and arbuscular mycorrhizal fungi (AMF) occupy the same ecological niche in the phytobiome of many agriculturally important crops. Arbuscular mycorrhizal fungi can enhance the resistance or tolerance of a plant to and previous studies have been undertaken to investigate the relationship between these organisms.

Plant-parasitic nematodes constrain chickpea () production, with annual yield losses estimated to be 14% of total global production. Nematode species causing significant economic damage in chickpea include root-knot nematodes (, , and ), cyst nematode (, and root-lesion nematode (). Reduced functionality of roots from nematode infestation leads to water stress and nutrient deficiency, which in turn lead to poor plant growth and reduced yield.

, a nematode species that feeds and reproduces in chickpea () roots, is widespread throughout the Mediterranean basin and Indian subcontinent. In Australia, it can cause yield losses up to approximately 25% of intolerant chickpea cultivars. Potential for improvement has been hindered by the narrow genetic diversity of cultivated chickpea and a limited world collection of original wild spp.

Liquid laundry detergent capsules contain concentrated liquid laundry detergent in a water-soluble polyvinyl alcohol membrane. To review 4652 exposures reported to the United Kingdom National Poisons Information Service (NPIS) and to assess the impact of regulatory changes on potential toxicity. Telephone enquiries to the NPIS and returned questionnaires for these products were analyzed for the period January 2008 to December 2018.

Article Synopsis
  • Iron poisoning has become less deadly globally, largely due to new packaging regulations and changes in how iron is used during pregnancy, but managing overdose cases remains challenging due to unclear guidelines for using antidotes.
  • The study analyzed data from the UK National Poisons Information Service (NPIS) from 2008 to 2017, focusing on cases of iron overdose involving single-agent ingestions, which showed age-related patterns among affected individuals.
  • Among 2,708 referrals, there were significant age peaks: younger children (under 6 years) and teenagers (13-20 years), with no significant correlation found between the reported dose of iron and the actual concentrations measured in blood after ingestion.

Objective: To determine the toxicity of rinse aids which are used as drying aids to remove water from crockery.

Methods: Enquiries to the UK National Poisons Information Service (NPIS) were analysed retrospectively for the period January 2008 to December 2016.

Results: There were 855 enquiries relating to 828 patients; children aged 5 years or less accounted for 91.

Background: Suspected poisoning is a common cause of hospital admission internationally. In the United Kingdom, the National Poisons Information Service (NPIS), a network of four poisons units, provides specialist advice to health professionals on the management of poisoning by telephone and via its online poisoning information and management database, TOXBASE.

Objective: To demonstrate the impact of NPIS telephone advice and TOXBASE guidance on poisoning-related referrals to emergency departments (ED) from primary healthcare settings.

Article Synopsis
  • Aconite poisoning is rare but can lead to dangerous heart rhythm issues, specifically ventricular dysrhythmias, due to the toxic alkaloids in the plant affecting sodium channels in the heart.
  • The review looks into various types of ventricular rhythm disturbances caused by aconitine, such as ventricular ectopy and fibrillation, highlighting the serious consequences of this poisoning.
  • The study aims to evaluate anti-dysrhythmic treatments from animal studies and human case reports to improve management strategies for ventricular dysrhythmias resulting from aconite poisoning.
