Coronavirus disease 2019 imposed dramatic changes on ENT service delivery. Pre-pandemic, such changes would have been considered potentially unsafe. This study outlines the impact of lockdown on the incidence and management of ENT emergencies at a large UK centre.

After modification of pre-pandemic guidelines, ENT emergency referrals data during the UK lockdown were prospectively captured. A comparative analysis was performed with retrospective data from a corresponding period in 2019.

An overall reduction (p < 0.001) in emergency referrals (n = 119) and admissions (n = 18) occurred during the lockdown period compared to the 2019 period (432 referrals and 290 admissions). Specifically, there were reduced admission rates for epistaxis (p < 0.0001) and tonsillar infection (p < 0.005) in the lockdown period. During lockdown, 90 per cent of patients requiring non-dissolvable nasal packing were managed as out-patients.

Coronavirus disease 2019 compelled modifications to pre-pandemic ENT guidelines. The enforced changes to emergency care appear to be safe and successfully adopted. Arguably, the measures have both economic and patient-related implications post-coronavirus disease 2019 and during future similar pandemics and lockdowns.

Drug classes are grouped based on their chemical and pharmacological properties, but prescription and illicit drugs differ in other important ways. Potential differences in genetic and environmental influences on the (mis)use of prescription and illicit drugs that are subsumed under the same class should be examined. Opioid and stimulant classes contain prescription and illicit forms differentially associated with salient risk factors (common route of administration, legality), making them useful comparators for addressing this etiological issue.

A total of 2410 individual Australian twins [Mage = 31.77 (s.d. = 2.48); 67% women] were interviewed about prescription misuse and illicit use of opioids and stimulants. Univariate and bivariate biometric models partitioned variances and covariances into additive genetic, shared environmental, and unique environmental influences across drug types.

Variation in the propensity to misuse prescription opioids was attributable to genes (41%) and unique environment (59%). Illicit opioid use was attributable to shared (71%) and unique (29%) environment. Prescription stimulant misuse was attributable to genes (79%) and unique environment (21%). Illicit stimulant use was attributable to genes (48%), shared environment (29%), and unique environment (23%). There was evidence for genetic influence common to both stimulant types, but limited evidence for genetic influence common to both opioid types. Bivariate correlations suggested that prescription opioid use may be more genetically similar to prescription stimulant use than to illicit opioid use.

Prescription opioid misuse may share little genetic influence with illicit opioid use. Future research may consider avoiding unitary drug classifications, particularly when examining genetic influences.

Single Point of Access (SPA) has been developed as a way of facilitating access to adult and older adult's community mental health services across South Staffordshire. Requests for assessments under the Mental Health Act 1983 are triaged and processed through SPA during working hours (09:00-17:00) Monday to Friday.

To explore the activity associated with these requests and to describe emerging trends.

Retrospective study of data regarding requests for assessment under the Mental Health Act 1983 in a SPA since its creation 2 years ago. Outcome of the request, outcome of the assessment, profession of the requester, and age and gender of the referred person has been collected.

343 requests were made since October 2005. 184 were male and 159 female. 264 were under 65 years of age. 92 were managed without the need to complete a formal assessment. From the 251 assessments carried out, 46 remained in the community, 41 were admitted informally and 164 were admitted under Section.

There appears to be little difference between gender and number of requests. Formal admissions appear to decrease since SPA has been in place. Trends will need to be explored against the introduction of the Mental Health Act 2007.

Studies suggest that alcohol consumption and alcohol use disorders have distinct genetic backgrounds.

We examined whether polygenic risk scores (PRS) for consumption and problem subscales of the Alcohol Use Disorders Identification Test (AUDIT-C, AUDIT-P) in the UK Biobank (UKB; N = 121 630) correlate with alcohol outcomes in four independent samples: an ascertained cohort, the Collaborative Study on the Genetics of Alcoholism (COGA; N = 6850), and population-based cohorts: Avon Longitudinal Study of Parents and Children (ALSPAC; N = 5911), Generation Scotland (GS; N = 17 461), and an independent subset of UKB (N = 245 947). Regression models and survival analyses tested whether the PRS were associated with the alcohol-related outcomes.

In COGA, AUDIT-P PRS was associated with alcohol dependence, AUD symptom count, maximum drinks (R2 = 0.47–0.68%, p = 2.0 × 10−8–1.0 × 10−10), and increased likelihood of onset of alcohol dependence (hazard ratio = 1.15, p = 4.7 × 10−8); AUDIT-C PRS was not an independent predictor of any phenotype. In ALSPAC, the AUDIT-C PRS was associated with alcohol dependence (R2 = 0.96%, p = 4.8 × 10−6). In GS, AUDIT-C PRS was a better predictor of weekly alcohol use (R2 = 0.27%, p = 5.5 × 10−11), while AUDIT-P PRS was more associated with problem drinking (R2 = 0.40%, p = 9.0 × 10−7). Lastly, AUDIT-P PRS was associated with ICD-based alcohol-related disorders in the UKB subset (R2 = 0.18%, p < 2.0 × 10−16).

AUDIT-P PRS was associated with a range of alcohol-related phenotypes across population-based and ascertained cohorts, while AUDIT-C PRS showed less utility in the ascertained cohort. We show that AUDIT-P is genetically correlated with both use and misuse and demonstrate the influence of ascertainment schemes on PRS analyses.

Despite established clinical associations among major depression (MD), alcohol dependence (AD), and alcohol consumption (AC), the nature of the causal relationship between them is not completely understood. We leveraged genome-wide data from the Psychiatric Genomics Consortium (PGC) and UK Biobank to test for the presence of shared genetic mechanisms and causal relationships among MD, AD, and AC.

Linkage disequilibrium score regression and Mendelian randomization (MR) were performed using genome-wide data from the PGC (MD: 135 458 cases and 344 901 controls; AD: 10 206 cases and 28 480 controls) and UK Biobank (AC-frequency: 438 308 individuals; AC-quantity: 307 098 individuals).

Positive genetic correlation was observed between MD and AD (rgMD−AD = + 0.47, P = 6.6 × 10−10). AC-quantity showed positive genetic correlation with both AD (rgAD−AC quantity = + 0.75, P = 1.8 × 10−14) and MD (rgMD−AC quantity = + 0.14, P = 2.9 × 10−7), while there was negative correlation of AC-frequency with MD (rgMD−AC frequency = −0.17, P = 1.5 × 10−10) and a non-significant result with AD. MR analyses confirmed the presence of pleiotropy among these four traits. However, the MD-AD results reflect a mediated-pleiotropy mechanism (i.e. causal relationship) with an effect of MD on AD (beta = 0.28, P = 1.29 × 10−6). There was no evidence for reverse causation.

This study supports a causal role for genetic liability of MD on AD based on genetic datasets including thousands of individuals. Understanding mechanisms underlying MD-AD comorbidity addresses important public health concerns and has the potential to facilitate prevention and intervention efforts.

Gambling disorder (GD), recognized in Diagnostic and Statistical Manual of Mental Disorders, Version 5 (DSM-5) as a behavioral addiction, is associated with a range of adverse outcomes. However, there has been little research on the genetic and environmental influences on the development of this disorder. This study reports results from the largest twin study of GD conducted to date.

Replication and combined analyses were based on samples of 3292 (mean age 31.8, born 1972–79) and 4764 (mean age 37.7, born 1964–71) male, female, and unlike-sex twin pairs from the Australian Twin Registry. Univariate biometric twin models estimated the proportion of variation in the latent GD liability that could be attributed to genetic, shared environmental, and unique environmental factors, and whether these differed quantitatively or qualitatively for men and women.

In the replication study, when using a lower GD threshold, there was evidence for significant genetic (60%; 95% confidence interval (CI) 45–76%) and unique environmental (40%; 95% CI 24–56%), but not shared environmental contributions (0%; 95% CI 0–0%) to GD liability; this did not significantly differ from the original study. In the combined analysis, higher GD thresholds (such as one consistent with DSM-5 GD) and a multiple threshold definitions of GD yielded similar results. There was no evidence for quantitative or qualitative sex differences in the liability for GD.

Twin studies of GD are few in number but they tell a remarkably similar story: substantial genetic and unique environmental influences, with no evidence for shared environmental contributions or sex differences in GD liability.

Anomalous aortic origin of a coronary artery is the second leading cause of sudden cardiac arrest/death in young athletes in the United States of America. Limited data are available regarding family history in this patient population.

Patients were evaluated prospectively from 12/2012 to 02/2017 in the Coronary Anomalies Program at Texas Children’s Hospital. Relevant family history included the presence of CHD, sudden cardiac arrest/death, arrhythmia/pacemaker use, cardiomyopathy, and atherosclerotic coronary artery disease before the age of 50 years. The presence of one or more of these in 1st- or 2nd-degree relatives was considered significant.

Of 168 unrelated probands (171 patients total) included, 36 (21%) had significant family history involving 19 (53%) 1st-degree and 17 (47%) 2nd-degree relatives. Positive family history led to cardiology referral in nine (5%) patients and the presence of abnormal tests/symptoms in the remaining patients. Coronary anomalies in probands with positive family history were anomalous right (27), anomalous left (five), single right coronary artery (two), myocardial bridge (one), and anomalous circumflex coronary artery (one). Conditions present in their family members included sudden cardiac arrest/death (15, 42%), atherosclerotic coronary artery disease (14, 39%), cardiomyopathy (12, 33%), CHD (11, 31%), coronary anomalies (3, 8%), myocardial bridge (1, 3%), long-QT syndrome (2, 6%), and Wolff–Parkinson–White (1, 3%).

In patients with anomalous aortic origin of a coronary artery and/or myocardial bridges, there appears to be familial clustering of cardiac diseases in approximately 20% of patients, half of these with early occurrence of sudden cardiac arrest/death in the family.

Prior research has documented shared heritable contributions to non-suicidal self-injury (NSSI) and suicidal ideation (SI) as well as NSSI and suicide attempt (SA). In addition, trauma exposure has been implicated in risk for NSSI and suicide. Genetically informative studies are needed to determine common sources of liability to all three self-injurious thoughts and behaviors, and to clarify the nature of their associations with traumatic experiences.

Multivariate biometric modeling was conducted using data from 9526 twins [59% female, mean age = 31.7 years (range 24–42)] from two cohorts of the Australian Twin Registry, some of whom also participated in the Childhood Trauma Study and the Nicotine Addiction Genetics Project.

The prevalences of high-risk trauma exposure (HRT), NSSI, SI, and SA were 24.4, 5.6, 27.1, and 4.6%, respectively. All phenotypes were moderately to highly correlated. Genetic influences on self-injurious thoughts and behaviors and HRT were significant and highly correlated among men [rG = 0.59, 95% confidence interval (CI) (0.37–0.81)] and women [rG = 0.56 (0.49–0.63)]. Unique environmental influences were modestly correlated in women [rE = 0.23 (0.01–0.45)], suggesting that high-risk trauma may confer some direct risk for self-injurious thoughts and behaviors among females.

Individuals engaging in NSSI are at increased risk for suicide, and common heritable factors contribute to these associations. Preventing trauma exposure may help to mitigate risk for self-harm and suicide, either directly or indirectly via reductions in liability to psychopathology more broadly. In addition, targeting pre-existing vulnerability factors could significantly reduce risk for life-threatening behaviors among those who have experienced trauma.

Minimum health requirements exist for entry into the UK armed forces. Both pre-existing and iatrogenic ENT conditions may impact on an individual's medical fitness and their ability to enter the forces.

The relevant literature was examined and military otolaryngology advisors were interviewed in order to define the ENT-specific conditions that restrict an individual joining the armed forces.

The ENT diseases and disabilities that inhibit an individual's ability to join the forces are described. Treatments that may facilitate or restrict recruitment are also discussed.

Members of the armed forces operate in arduous environments and are required to pass a screening medical assessment before joining. Personnel may be isolated away from specialist care and therefore cannot be dependent on specialist devices or medicines. This paper aims to arm ENT specialists with occupational knowledge to enable them to correctly counsel patients and offer appropriate treatment.

Successful patient outcomes in the setting of ocular emergencies depend on correct recognition and assessment as well as appropriate initial management. The purpose of this study is to describe the clinico-epidemiological findings and management options in patients with ocular injuries in the emergency room of a rural hospital.

In this retrospective review the records of patients who were treated for ocular trauma from June 2010 to December 2010 in the emergency room of MM Institute of Medical Sciences and Research, Mullana (Ambala) were reviewed. The following data for all patients were recorded: age, sex, date and time of injury, involved eye, circumstance and mechanism of injury, initial visual acuity, details of appropriate investigation, immediate management and outcome.

A total 46 patients were included in the study. Young adult male patients were more commonly involved. Most of the patients presented within 12hours of injury. Left eye was involved in 14 patients; right in 12 and 10 patients had injuries to both eyes. Most common mode of injury was mechanical. The patients who sustained bilateral ocular injuries were due to chemical burns (7 cases) and electrocution (3 cases). Most of the patients were managed conservatively. The surgical treatment offered were repair of corneal tears, removal of foreign bodies. The visual outcome was excellent in most of the patients.

Ocular injuries can have wide range of etiological factors and presentation and assessment of ocular emergencies can be made difficult by a lack of sophisticated facilities. However, a concise patient history, general observation and basic ocular tests can lead to a firm diagnosis and thereby appropriate management.
