Article Synopsis
  • The study aims to identify factors associated with cholesteatoma, a type of middle ear disease, in a large UK cohort, highlighting established risk factors like male sex and chronic ear infections, as well as less-clear associations like deprivation and smoking.
  • Researchers compared 1140 cholesteatoma cases with 4551 non-cholesteatoma cases and nearly half a million healthy controls, using logistic regression to analyze demographic factors such as age, sex, and deprivation.
  • The findings indicate significant associations between cholesteatoma and factors like male sex (33% higher odds), older age, and deprivation, while showing overlaps with other inflammatory ear conditions and suggesting that both common and distinct factors influence cholesteatoma development.

Article Synopsis
  • RASopathies, like neurofibromatosis type 1 (NF1), lead to continuous activation of the Ras/MAPK pathway and often feature multiple Café au Lait Macules (CALMs).
  • The study aimed to identify genes related to melanocyte growth and movement by analyzing skin samples from both CALM and unaffected areas in NF1 patients, revealing the impact of specific genetic variations.
  • Findings indicated that the formation of CALMs is linked to genetic losses that enhance Ras/MAPK and Wnt signaling, coupled with decreased levels of a protective protein (PEDF), which promotes cell growth and movement in NF1-associated melanoma.

Iron forms essential cofactors used by many nuclear enzymes involved in genome maintenance. However, unchaperoned nuclear iron may represent a threat to the surrounding genetic material as it promotes redox toxicity that may affect DNA integrity. Safely handling intracellular iron implies metal transfer and cofactor assembly processes based on protein-protein interactions.

Article Synopsis
  • The study assessed current clinical practices for olfactory dysfunction (OD) among ENT surgeons, focusing on the differences between the UK and international approaches.
  • Most UK clinicians do not perform psychophysical smell testing, with rhinologists conducting it more frequently than non-rhinologists, while international respondents reported higher testing rates.
  • The survey highlighted barriers like time and funding, revealed a desire for more training in smell testing among 75% of participants, and noted that patient-reported outcomes are rarely used in both the UK and internationally.

Following the European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) treatment algorithm for chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP), patients suffering from severe uncontrolled CRSwNP are recommended to receive oral corticosteroids, (revision) sinus surgery, systemic biologicals and/or aspirin treatment after desensitization (ATAD). Given the major differences in indications, outcomes, practical considerations, risks and costs of these key pillars of treatment, there is a growing need to define criteria for each treatment option and list the clinically relevant and major considerations for them. This EUFOREA document therefore provides an expert panel overview of the expected outcomes, specific considerations and (contra)indications of the five major treatment arms of severe uncontrolled CRSwNP: oral corticosteroids, primary and revision sinus surgery, biological treatment and ATAD.

Olfactory dysfunction affects approximately 20% of the population globally, with incidence increasing over the age of 60. The pathophysiology is complex, not yet fully understood, and depends on many factors, including the underlying cause. Despite this, the present literature on olfaction is limited due to significant heterogeneity in methodological approaches.

Background: Smell loss is a common problem with an estimated 5% of the population having no functioning sense of smell. Viral causes of smell loss are the second most common cause and the coronavirus (COVID-19) pandemic is estimated to have caused 20,000 more people this year to have a lasting loss of smell. Isolation, depression, anxiety, and risk of danger from hazards such as toxic gas and spoiled food are all negative impacts.

Iron is an essential nutrient required by all cells but used primarily for red blood cell production. Because humans have no effective mechanism for ridding the body of excess iron, the absorption of dietary iron must be precisely regulated. The critical site of regulation is the transfer of iron from the absorptive enterocyte to the portal circulation via the sole iron efflux transporter, ferroportin.

Statement Of Problem: Evaluating the effectiveness of the management of Olfactory Dysfunction (OD) has been limited by a paucity of high-quality randomised and/or controlled trials. A major barrier is heterogeneity of outcomes in such studies. Core outcome sets (COS) - standardized sets of outcomes that should be measured/reported as determined by consensus-would help overcome this problem and facilitate future meta-analyses and/or systematic reviews (SRs).

Background: Vitamin E (vit E) is an essential nutrient that functions as a lipophilic antioxidant and is used clinically to treat nonalcoholic fatty liver disease, where it suppresses oxidative damage and impedes the progression of steatosis and fibrosis. Mice lacking a critical liver iron-trafficking protein also manifest steatosis because of iron-mediated oxidative damage and are protected from liver disease by oral vit E supplements.

Objectives: We aimed to examine the role of dietary vit E supplementation in modulating iron-sensing regulatory systems and nonheme iron levels in mouse liver.
