Subjective tinnitus is a common symptom, and there is often an underlying otological cause. This study investigated the degree of tinnitus-related annoyance in patients with chronic otitis media and analysed whether associations with tinnitus severity exist.
Method
The multinational collaborative Chronic Otitis Media Questionnaire-12 study collected prospective data on 478 adult patients suffering from chronic otitis media across 9 otology referral centres in 8 countries. Based on this dataset, we investigated tinnitus severity using participant responses to item 7 of a native version of the Chronic Otitis Media Questionnaire-12.
Results
With respect to tinnitus severity, 23.8 per cent, 17.4 per cent, 15.5 per cent, and 43.4 per cent of participants reported no, minor, moderate, and major inconvenience or greater, respectively. The absence of ear discharge, absence of cholesteatoma, and poorer disease-specific health-related quality-of-life were associated with increased tinnitus severity in patients with chronic otitis media, whereas age, hearing disability and geographical region showed no association.
Conclusion
This analysis provided novel insight into potential risk factors for tinnitus in patients with chronic otitis media.
Bipolar disorder is associated with premature mortality, but evidence is mostly derived from Western countries. There has been no research evaluating shortened lifespan in bipolar disorder using life-years lost (LYLs), which is a recently developed mortality metric taking into account illness onset for life expectancy estimation. The current study aimed to examine the extent of premature mortality in bipolar disorder patients relative to the general population in Hong Kong (HK) in terms of standardised mortality ratio (SMR) and excess LYLs, and changes of mortality rate over time.
Methods
This population-based cohort study investigated excess mortality in 12 556 bipolar disorder patients between 2008 and 2018, by estimating all-cause and cause-specific SMRs, and LYLs. Trends in annual SMRs over the 11-year study period were assessed. Study data were retrieved from a territory-wide medical-record database of HK public healthcare services.
Results
Patients had higher all-cause [SMR: 2.60 (95% CI: 2.45–2.76)], natural-cause [SMR: 1.90 (95% CI: 1.76–2.05)] and unnatural-cause [SMR: 8.63 (95% CI: 7.34–10.03)] mortality rates than the general population. Respiratory diseases, cardiovascular diseases and cancers accounted for the majority of deaths. Men and women with bipolar disorder had 6.78 (95% CI: 6.00–7.84) years and 7.35 (95% CI: 6.75–8.06) years of excess LYLs, respectively. The overall mortality gap remained similar over time, albeit slightly improved in men with bipolar disorder.
Conclusions
Bipolar disorder is associated with increased premature mortality and substantially reduced lifespan in a predominantly Chinese population, with excess deaths mainly attributed to natural causes. Persistent mortality gap underscores an urgent need for targeted interventions to improve physical health of patients with bipolar disorder.
It is important to understand the temporal trend of the paediatric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load to estimate the transmission potential of children in schools and communities. We determined the differences in SARS-CoV-2 viral load dynamics between nasopharyngeal samples of infected asymptomatic and symptomatic children. Serial cycle threshold values of SARS-CoV-2 from the nasopharynx of a cohort of infected children were collected for analysis. Among 17 infected children, 10 (58.8%) were symptomatic. Symptomatic children, when compared to asymptomatic children, had higher viral loads (mean cycle threshold on day 7 of illness 28.6 vs. 36.7, P = 0.02). Peak SARS-CoV-2 viral loads occurred around day 2 of illness in infected children. Although we were unable to directly demonstrate infectivity, the detection of significant amount of virus in the upper airway of asymptomatic children suggest that they have the potential to shed and transmit SARS-CoV-2. Our study highlights the importance of contact tracing and screening for SARS-CoV-2 in children with epidemiological risk factors regardless of their symptom status, in order to improve containment of the virus in the community, including educational settings.
To describe the infection control preparedness measures undertaken for coronavirus disease (COVID-19) due to SARS-CoV-2 (previously known as 2019 novel coronavirus) in the first 42 days after announcement of a cluster of pneumonia in China, on December 31, 2019 (day 1) in Hong Kong.
Methods:
A bundled approach of active and enhanced laboratory surveillance, early airborne infection isolation, rapid molecular diagnostic testing, and contact tracing for healthcare workers (HCWs) with unprotected exposure in the hospitals was implemented. Epidemiological characteristics of confirmed cases, environmental samples, and air samples were collected and analyzed.
Results:
From day 1 to day 42, 42 of 1,275 patients (3.3%) fulfilling active (n = 29) and enhanced laboratory surveillance (n = 13) were confirmed to have the SARS-CoV-2 infection. The number of locally acquired case significantly increased from 1 of 13 confirmed cases (7.7%, day 22 to day 32) to 27 of 29 confirmed cases (93.1%, day 33 to day 42; P < .001). Among them, 28 patients (66.6%) came from 8 family clusters. Of 413 HCWs caring for these confirmed cases, 11 (2.7%) had unprotected exposure requiring quarantine for 14 days. None of these was infected, and nosocomial transmission of SARS-CoV-2 was not observed. Environmental surveillance was performed in the room of a patient with viral load of 3.3 × 106 copies/mL (pooled nasopharyngeal and throat swabs) and 5.9 × 106 copies/mL (saliva), respectively. SARS-CoV-2 was identified in 1 of 13 environmental samples (7.7%) but not in 8 air samples collected at a distance of 10 cm from the patient’s chin with or without wearing a surgical mask.
Conclusion:
Appropriate hospital infection control measures was able to prevent nosocomial transmission of SARS-CoV-2.
The Chronic Otitis Media Questionnaire 12 was developed initially in the UK to assess patient-reported health-related quality of life associated with chronic otitis media. This study aimed to determine whether this tool is applicable to the Russian population, which has a materially different healthcare system.
Method:
A total of 108 patients with different forms of chronic otitis media completed the Russian Chronic Otitis Media Questionnaire 12.
Results:
The average Russian Chronic Otitis Media Questionnaire 12 score was 19.4 (standard deviation = 8.3). The internal consistency of the Russian Chronic Otitis Media Questionnaire 12 was high, with a Cronbach's alpha value of 0.860.
Conclusion:
The Russian version of the Chronic Otitis Media Questionnaire 12 was found to be a reliable tool for the assessment of health-related quality of life in patients with chronic otitis media. This sets the scene for international collaboration, using this tool to assess the effectiveness of surgical treatments even amongst countries with different healthcare systems.
To study the association between gastrointestinal colonization of carbapenemase-producing Enterobacteriaceae (CPE) and proton pump inhibitors (PPIs).
METHODS
We analyzed 31,526 patients with prospective collection of fecal specimens for CPE screening: upon admission (targeted screening) and during hospitalization (opportunistic screening, safety net screening, and extensive contact tracing), in our healthcare network with 3,200 beds from July 1, 2011, through December 31, 2015. Specimens were collected at least once weekly during hospitalization for CPE carriers and subjected to broth enrichment culture and multiplex polymerase chain reaction.
RESULTS
Of 66,672 fecal specimens collected, 345 specimens (0.5%) from 100 patients (0.3%) had CPE. The number and prevalence (per 100,000 patient-days) of CPE increased from 2 (0.3) in 2012 to 63 (8.0) in 2015 (P<.001). Male sex (odds ratio, 1.91 [95% CI, 1.15–3.18], P=.013), presence of wound or drain (3.12 [1.70–5.71], P<.001), and use of cephalosporins (3.06 [1.42–6.59], P=.004), carbapenems (2.21 [1.10–4.48], P=.027), and PPIs (2.84 [1.72–4.71], P<.001) in the preceding 6 months were significant risk factors by multivariable analysis. Of 79 patients with serial fecal specimens, spontaneous clearance of CPE was noted in 57 (72.2%), with a median (range) of 30 (3–411) days. Comparing patients without use of antibiotics and PPIs, consumption of both antibiotics and PPIs after CPE identification was associated with later clearance of CPE (hazard ratio, 0.35 [95% CI, 0.17–0.73], P=.005).
CONCLUSIONS
Concomitant use of antibiotics and PPIs prolonged duration of gastrointestinal colonization by CPE.
To determine the outcome of myringoplasty as undertaken by ENT surgeons in the UK, and to assess the current systems available for providing national outcome data.
Methods:
A prospective national multicentre audit was conducted involving multiple hospitals throughout the UK. Participants consisted of ENT surgeons practising in the UK.
Results:
Data were prospectively collected over a three-year period between 1 March 2006 and 1 March 2009 using the web-based Common Otology Database. In total, 33 surgeons provided valid and complete data for 495 procedures. The overall closure rate for myringoplasty was 89.5 per cent. The average hearing gain for successful primary myringoplasties was 9.14 dB (standard deviation = 10.62). The Common Otology Database provided an effective platform for capturing outcome data.
Conclusion:
Myringoplasty is a safe and effective procedure in the UK. With the introduction of revalidation by the General Medical Council, participation in national audits will be mandatory in the future. This study demonstrates that a web-based audit tool would be suitable for performing such audits.
The 5S model proposes five hierarchical levels (systems, summaries, synopses, syntheses and studies) of pre-appraised evidence to guide evidence-based practice. This review aimed to identify and summarise pre-appraised evidence at the highest available 5S level for the management of different subsets of otitis media: acute otitis media, otitis media with effusion, chronic suppurative otitis media and cholesteatoma in both adults and children.
Method:
Data sources were pre-appraised evidence resources. Evidence freely available from sources at the highest available level of the 5S model were summarised for this review.
Results:
System level evidence exists for acute otitis media and otitis media with effusion. Summary level evidence exists for recurrent acute otitis media and medical management of chronic suppurative otitis media. There is an absence of randomised controlled trials to prove the efficacy of surgical management of chronic suppurative otitis media and cholesteatoma.
Conclusion:
Until randomised controlled trial data are generated, consensus publications on the surgical management of chronic suppurative otitis media and cholesteatoma should be used to guide best practice.
Individuals at ultra-high risk (UHR) for psychosis show reduced neurocognitive performance across domains but it is unclear which reductions are associated with transition to frank psychosis. The aim of this study was to investigate differences in baseline neurocognitive performance between UHR participants with (UHR-P) and without transition to psychosis (UHR-NP) and a healthy control (HC) group and examine neurocognitive predictors of transition over the medium to long term.
Method
A sample of 325 UHR participants recruited consecutively from the Personal Assessment and Crisis Evaluation (PACE) Clinic in Melbourne and 66 HCs completed a neurocognitive assessment at baseline. The UHR group was followed up between 2.39 and 14.86 (median = 6.45) years later. Cox regression was used to investigate candidate neurocognitive predictors of psychosis onset.
Results
The UHR group performed more poorly than the HC group across a range of neurocognitive domains but only performance on digit symbol coding and picture completion differed between the groups. The risk of transition was only significantly associated with poorer performance on visual reproduction [hazard ratio (HR) 0.919, 95% confidence interval (CI) 0.876–0.965, p = 0.001] and matrix reasoning (HR 0.938, 95% CI 0.883–0.996, p = 0.037). These remained significant even after controlling for psychopathology at baseline.
Conclusions
This study is the longest follow-up of an UHR sample to date. UHR status was associated with poorer neurocognitive performance compared to HCs on some tasks. Cognition at identification as UHR was not a strong predictor of risk for transition to psychosis. The results suggests the need to include more experimental paradigms that isolate discrete cognitive processes to better understand neurocognition at this early stage of illness.
Subclinical psychotic experiences during adolescence may represent liability for developing psychotic disorder. Both coping style and the degree of persistence of psychotic experiences may play a role in the progression to clinical psychotic disorder, but little is known about the causal relationship between the two.
Method
Path modelling was used to examine longitudinal relationships between subclinical positive psychotic experiences and three styles of coping (task-, emotion- and avoidance-oriented) in an adolescent general population sample (n=813) assessed three times in 3 years. Distinct developmental trajectories of psychotic experiences, identified with growth mixture modelling, were compared on the use of these coping styles.
Results
Over time, emotion-oriented coping in general was bi-directionally related to psychotic experiences. No meaningful results were found for task- or avoidance-oriented coping. Females reported using a wider range of coping styles than males, but the paths between coping and psychotic experiences did not differ by gender. Persistence of psychotic experiences was associated with a greater use of emotion-oriented coping, whereas a decrease in experiences over time was associated with an increased use of task-orientated coping.
Conclusions
Emotion-oriented coping is the most important coping style in relation to psychotic experiences, as it may contribute to a ‘vicious cycle’ and is associated with persistence of experiences. In addition, more task-oriented coping may result in a decrease in psychotic experiences. Results suggest that opportunities for intervention may already be present at the level of subclinical psychosis.
Canalicular blockage of the lacrimal system still remains a major challenge for oculoplastic surgeons. The conventional treatment of conjunctival dacryocystorhinostomy using the Lester Jones bypass tube is often associated with tube migration and foreign body reaction. The authors report a new technique to reconstruct the lacrimal passage on a single patient with severe canalicular obstruction following repeated failures from previous Lester Jones tube operations. An epithelial-lined tube was recreated between the nasal cavity and the conjunctiva using a superiorly based mucoperichondrial flap from the nasal septum (Ipswich lacrimal tube). The pedicle of the flap was divided six weeks following the operation. The patient was still symptom free two years following the operation together with a positive dye test confirming the patency of the new lacrimal tube.
Both hydroxyapatite (Ha) and titanium (Ti) are well-accepted alloplastic materials for ossicular prostheses. Many different designs of Ha and Ti prostheses are presently available. Fourteen surgeons of different seniority and surgical experience were asked to ‘test-drive’ four different types of ossicular prostheses in cadaveric temporal bones to investigate the user-friendliness of these protheses. The Goldenberg design Ha incus prosthesis and the Dusseldorf design Bell Ti prosthesis were used as partial ossicular replacement prostheses (PORP). The Richards design Ha incus-stapes prosthesis and the Dusseldorf design Aerial Ti prosthesis were used as a total ossicular replacement prostheses (TORP). Nine out of 14 surgeons found the Ha PORP to be more user-friendly because of the notch design in the head. The Ti prosthesis was found to be more difficult to manipulate because it was too light. Half of the surgeons preferred the Ti TORP because of the open design of the top-plate. The Ha TORP was thought to be too top-heavy and to have a tendency to fall over.
Oto-endoscopes allow surgeons to control blind pockets within the middle ear. Many surgeons credit the reduction of residual cholesteatoma in their practice to the use of oto-endoscopes. Since 1988, the author has been using rigid endoscopes in combination with the operating microscope in cholesteatoma surgery. Between 1988 and 1999, 231 primary cholesteatoma operations were performed. The operations included closed cavity mastoidectomy (53 patients), small cavity mastoidectomy (115 patients), open mastoidectomy with primary canal wall reconstruction (44 patients) or mastoid obliteration (19 patients). The median follow-up period was 6.5 years. The incidence of residual cholesteatoma is closed cavity mastoidectomy (9.4 per cent) was found to be similar to that of open cavity mastoidectomy (8.7 per cent). Site analysis of the residual cholesteatoma revealed an incidence of 3.6 per cent in the epitympanum, 10.5 per cent in the sinus tympani and 0.7 per cent in the mastoid bowl. This study showed that residual cholesteatoma has not been eliminated with the use of middle-ear endoscopy, although the incidence has reduced the figures for closed cavity mastoidectomy to single figures.
The outcome of otitis media with effusion (OME) in children is generally good. However, it is less clear in adults. All adult patients who had a ventilation tube inserted for OME at the Ipswich Hospital between 1996 and 1997 were studied. Of 53 patients studied, 28 had had a previous history of ventilation tube insertion. Furthermore, at 15–27 months following ventilation tube insertion, the ventilation tube had already extruded in 31 patients and the OME had already recurred in 19 of these. Endoscopic examination revealed that many patients still had evidence of inflammation at the lateral nasal wall (26.4 per cent) and at the eustachian tube orifice (51 per cent). There is also a strong history of atopy in the studied group and the skin prick test was positive in 57 per cent of the patients. This study shows that many patients with adult-onset OME have underlying pathology that could lead to recurrence of OME following ventilation tube extrusion.
Middle-ear adenoma has been reported only in small numbers by surgeons. The few large series reported have been presented by histopathologists. We add two cases of middle-ear adenoma to the published literature, together with pre-, per- and post-operative imaging of one case, as a demonstration of this rare clinical entity. We discuss the pathology of middle-ear adenoma, its diagnosis and treatment, and suggest ways of improving its management.
In spite of previously favourable reports on day-case adenoidectomy, thereare still worries amongst otolaryngologists that such practice is unsafe, especially in arural environment. A national survey was therefore carried out which shows that only 41 per cent of respondents perform adenoidectomy routinely as day-case, and even fewer in rural areas. A regional audit on day-case adenoidectomy, covering five hospitals, was conducted in East Anglia. Between 1994 to 1995, 73 day-case adenoidectomies were performed and the outcome was compared to those of 183 in-patient adenoidectomies during the same period. The children in the day-case group recovered post-operatively even better than the in-patient group. None of them stayed overnight or required re-admission. There was no increased in post-operative consultation to the general practitioner. The parents in the day-case group were mostly in favour of the day-case arrangement (88 per cent). The results suggest that day-case adenoidectomy is safe and popular with parents even in a rural environment.
Labyrinthectomy for unilateral Meniere's disease may be complicated by persistent unsteadiness post-operatively. The aim of this study is to identify the unfavourable factors in recovery following labyrinthectomy. Twenty-one patients gave a detailed history and underwent neuro-otological, opthalmic and cardiovascular examination, as well as psychological and psychiatric assessment. Sedentary occupations, external health locus of control, extraverted personality, and an anxious and/or depressed psychiatric state were associated with poor post-operative recovery. These factors therefore should be taken into consideration in the pre-operative assessment and post-operative rehabilitation of labyrinthectomy patients.
