Surgical smoke: how an issue in healthcare fits a planetary health framework.

AIM: The smoke generated from electrocautery machines may be harmful to health. Healthcare in general, and surgery in particular, has a large environmental footprint. The aims of this study were to discover what healthcare workers thought about the problem of electrocautery smoke, the idea of a surgical smoke-free policy, and to formulate ideas on how the matter could be approached in an environmentally and socially responsible way. METHOD: Operating room personnel in a tertiary referral hospital were invited to complete a survey about electrocautery smoke: perceived risks, current exposure, and measures to minimise exposure. Quantitative data were analysed in a generalised linear model, and qualitative data by reflexive thematic analysis within a constructivist theoretical framework. RESULTS: The survey response rate was 463/1234 (38%). Most supported a smoke-free policy (89%). Support for a policy was positively correlated with the perceived risk of electrocautery smoke (p<0.001. Support was lower amongst males (p<0.05). Themes from the qualitative analysis developed around nature, society and technology. A framework was developed consisting of earth and its ecosystems, human health, governance, economics, society, and the interconnected of these systems. CONCLUSION: Although smoke-free policies form part of the solution to electrocautery smoke, they are not the whole solution. Healthcare issues, in this case the issue of electrocautery smoke, could be tackled within a planetary health healthcare framework, promoting a systems approach. Applicability of the framework requires confirmation by further research.

COVID-19 vaccine associated cervical lymphadenopathy: a case series.

BACKGROUND: COVID-19 is an evolving worldwide pandemic causing significant morbidity and mortality. COVID-19 vaccinations have been developed to increase immunity against the virus. In New Zealand, the Pfizer BioNTech mRNA vaccine has been provisionally approved for use. Axillary lymphadenopathy is a recognized side effect of the mRNA vaccine, however cervical lymphadenopathy has also been reported. Due to a wide range of differential diagnoses, the finding of cervical lymphadenopathy requires thorough investigation which can include imaging and invasive diagnostic procedures. METHODS: Five patients were identified by otorhinolaryngology (ORL) consultants at Whangarei Base Hospital and Waikato Hospital between 15/7/2021 and 21/12/2021 after being investigated through high suspicion of cancer triage pathways set by the New Zealand Ministry of Health. Inclusion criteria were adult patients with cervical lymphadenopathy following vaccination. Exclusion criteria were no history of vaccination or lymphadenopathy present before vaccination. RESULTS: All patients were identified to have cervical lymphadenopathy on radiological imaging and a recent history of COVID-19 vaccination with the Pfizer BioNTech vaccine. Interval vaccination to fine needle aspiration time ranged between 41 and 76 days. All patients had cytological or histological diagnosis showing reactive findings or interval imaging showing resolution of lymphadenopathy. CONCLUSION: With increasing levels of COVID-19 vaccination and booster vaccinations we will continue to see cases of COVID-19 vaccine associated cervical lymphadenopathy. We highlight the importance of taking a COVID-19 vaccination history and including COVID-19 associated cervical lymphadenopathy in the differential diagnosis of presentation with a neck lump.

Fatal epistaxis in a case of common variable immunodeficiency: A case report and review of the literature.

Common variable immunodeficiency (CVID) is a primary immunodeficiency disease. We present a case of a patient with CVID complicated by rhinosinusitis with granulomatous inflammation. Treatment for this patient was challenging with regards recognition of the granulomatous manifestation as well as treatment in the setting immunodeficiency and was ultimately unsuccessful.
