Video Laryngoscope Assistance in Button Battery Retrieval.

Foreign body ingestion remains a common cause of pediatric emergency surgery with button battery ingestion of particular concern. Newer, higher power lithium batteries can cause catastrophic damage of the gastrointestinal tract through erosion of mucosa into surrounding structures. Prompt diagnosis and treatment are paramount. We present a case of an 11-month-old with a button battery lodged in the proximal esophagus. The extraction was difficult and only made possible with the assistance of a video laryngoscope. We make the case for more routine usage of video laryngoscopy for removal of foreign bodies in the upper esophagus.

Implications of parenteral chemotherapy dose standardisation in a tertiary oncology centre.

BACKGROUND: Dose banding parenteral chemotherapy has the potential to optimise aseptic unit capacity and reduce drug expenditure without compromising the service provided. METHODS: Dose banding tables from NHS England were implemented into the electronic chemotherapy prescribing system. Compliance to the dose bands was analysed and submitted quarterly. Analysis of drug expenditure, drug use and cost per milligram data was also collected. RESULTS: Expenditure on the 17 drugs identified in the 2016/17 dose standardisation CQUIN reduced by approximately £100,000 per month over the CQUIN despite an increase in the number of prescribed doses of these drugs. At the beginning of the year, the percentage of work compounded in house was 60%, which was reduced to 51% of total workload at the end of the year due to outsourcing commonly prescribed doses from commercial pharmaceutical aseptic manufacturers. CONCLUSION: Dose banding parenteral chemotherapy is an efficient cost-saving strategy which also can help to increase the capacity of the aseptic unit.

Acute molecular perturbation of inducible nitric oxide synthase with an antisense approach enhances neuronal preservation and functional recovery after contusive spinal cord injury.

Inducible nitric oxide synthase (iNOS) is a key mediator of inflammation and oxidative stress produced during pathological conditions, including neurodegenerative diseases and central nervous system (CNS) injury. iNOS is responsible for the formation of high levels of nitric oxide (NO). The production of highly reactive and cytotoxic NO species, such as peroxynitrite, plays an important role in secondary tissue damage. We have previously demonstrated that acute administration of iNOS antisense oligonucleotides (ASOs) 3 h after moderate contusive spinal cord injury (SCI) potently inhibits iNOS-mediated increases in NO levels, leading to reduced blood-spinal cord barrier permeability, decreased neutrophil accumulation, and less neuronal cell death. In the current study we investigated if iNOS ASOs could also provide long-term (10-week) histological and behavioral improvements after moderate thoracic T8 contusive SCI. Adult rats were randomly assigned to three groups (n=10/group): SCI alone, SCI and mixed base control oligonucleotides (MBOs), or SCI and iNOS ASOs (200 nM). Oligonucleotides were administered by spinal superfusion 3 h after injury. Behavioral analysis (Basso-Beattie-Bresnahan [BBB] score and subscore) was employed weekly for 10 weeks post-SCI. Although animals treated with iNOS ASOs demonstrated no significant differences in BBB scores compared to controls, subscore analysis revealed a significant improvement in foot positioning, trunk stability, and tail clearance. Histologically, while no gross improvement in preserved white and gray matter was observed, greater numbers of surviving neurons were present adjacent to the lesion site in iNOS ASO-treated animals than controls. These results support the effectiveness of targeting iNOS acutely as a therapeutic approach after SCI.
