Complications of acute mastoiditis in a paediatric population at a UK Tertiary Centre: A retrospective review.

OBJECTIVES: Acute mastoiditis (AM) and its associated intra and extracranial complications are rare complications of acute otitis media. However, they are associated with a high morbidity. The management of AM with complications carries significant variations in approach. We aimed to evaluate the presentation of children with AM with complications to a tertiary referral centre in the United Kingdom and describe evolution of the treatment approaches. METHODS: We undertook a retrospective chart review of all children admitted with AM to the University Hospitals of Leicester between 2013 and 2022. RESULTS: Twenty-seven children were included in this study: 7 patients had sigmoid sinus thrombosis (SST), 4 had an intracranial collection, 3 had cranial nerve palsy and 16 had a subperiosteal abscess (SPA); some patients had more than 1 complication. In this study, treatment of SPA with incision and drainage (I&D) and grommet insertion was effective, as all patients treated with grommet insertion and I&D recovered well and did not require a subsequent cortical mastoidectomy. All patients with SST received anticoagulation and intravenous (IV) antibiotics; surgical input consisted of grommet insertion alone and cortical mastoidectomy was not routinely performed in these patients. CONCLUSION: In our series, management of SPA with grommet insertion and drainage had good outcomes. SST management mainly consisted of IV antibiotics, anticoagulation and grommet insertion with good recovery. The evidence to guide the management of complications of mastoiditis is of poor quality and further research is needed to clarify the optimal management of these complications.

Food bolus and oesophageal foreign body: a summary of the evidence and proposed management process.

PURPOSE: Food bolus and oesophageal foreign bodies are a common presentation that may be managed by otolaryngologists, gastroenterologists, acute medicine physicians and accident and emergency. The condition is highly variable with presentations ranging from well patients whose obstruction spontaneously passes to peri-arrest with severe aspiration or impending airway compromise. Management of this condition is heterogeneous and often depends on the specialty the patient is originally admitted under. There exist European and American guidelines from the perspective of gastroenterology, but there are no UK-based guidelines and limited consideration of the role of the otolaryngologists and rigid oesophagoscopy. METHODS: An extensive literature search was carried out to generate conclusions on key management questions for food bolus and oesophageal foreign bodies. This was then summarised into both a written summary of the evidence and a graphical decision tree. RESULTS: This paper is a review article and presents conclusions regarding management options for food bolus and oesophageal foreign bodies. CONCLUSION: This article considers the current evidence surrounding investigation and management of oesophageal food bolus and foreign body. It draws conclusions regarding presentation, investigation and subsequent operative treatment. As part of this process, we propose a graphical decision tree to assist in management decisions.

Comparison of clinical estimations and radiological measurements in the context of paediatric cervical masses: How accurate are we?

OBJECTIVES: Cervical masses represent a common presentation to the paediatric ENT outpatient clinic. Despite their high prevalence, few represent an underlying malignant pathology. Currently, there is no universally accepted algorithm for management of such cases in the United Kingdom. Local guidance often centres around clinical interpretation of size when determining the need for investigation. With such emphasis placed on size, the authors sought to investigate the accuracy of physician palpation and in turn explore the validity of common referral pathways. METHODS: A retrospective methodology was used to address the research objective. All paediatric ultrasound scans conducted during a 24-month period were reviewed to compare the clinical and radiological assessments of diameter. A 2 tailed paired student's t-test was selected to evaluate the differences between the two measurements and ultimately assess clinician accuracy. RESULTS: 753 paediatric cervical ultrasound scans were conducted during the 2-year period. Initial analysis identified three discrete ultrasonographically diagnostic groups: lymph nodes (n = 532), non-lymph node masses (n = 162) and normal anatomy (n = 59). Further analysis of clinical estimation and radiological measurement demonstrated a statistically significant difference (p < 0.02) for the lymph-node group. A statistically significant difference was not demonstrated within the non-lymph node group (p = 0.66). When clinician assessment resulted in a value outside of what was considered accurate, lymph node sizes were predominantly overestimated (62/91, 68%). Conversely, non-lymph node masses where the clinical measurement was not within 5 mm of the ultrasound measurement were more commonly underestimated in size (11/45, 55%) but this was not statistically significant. CONCLUSIONS: Our study demonstrates a statistically significant tendency for clinicians to overestimate paediatric cervical lymphadenopathy. Calliper measurement may further improve accuracy of assessment.

Tracheotomy in COVID-19 patients: Optimizing patient selection and identifying prognostic indicators.

BACKGROUND: Tracheotomy, through its ability to wean patients off ventilation, can shorten ICU length of stay and in doing so increase ICU bed capacity, crucial for saving lives during the COVID-19 pandemic. To date, there is a paucity of patient selection criteria and prognosticators to facilitate decision making and enhance precious ICU capacity. METHODS: Prospective study of COVID-19 patients undergoing tracheotomy (n = 12) over a 4-week period (March-April 2020). Association between preoperative and postoperative ventilation requirements and outcomes (ICU stay, time to decannulation, and death) were examined. RESULTS: Patients who sustained FiO2 ≤ 50% and PEEP ≤ 8 cm H2 O in the 24 hours pretracheotomy exhibited a favorable outcome. Those whose requirements remained below these thresholds post-tracheotomy could be safely stepped down after 48 hours. CONCLUSION: Sustained FiO2 ≤ 50% and PEEP ≤ 8 cm H2 O in the 48 hours post-tracheotomy are strong predictive factors for a good outcome, raising the potential for these patients to be stepped down early, thus increasing ICU capacity.

Lemierre's syndrome: a pain in the neck with far-reaching consequences.

Lemierre's syndrome is a potentially life-threatening consequence of oropharyngeal and ear infections and often results in critical care admission and even intubation. Due to the multisystem manifestation, multiple teams may initially be involved in the care, some of which may be unfamiliar with the features and usual clinical course. This report describes a case in a 36-year-old woman with the classic features of internal jugular vein thrombosis and septic emboli to the lungs secondary to an oropharyngeal infection. Treatment comprised antibiotic therapy, anticoagulation and fluid resuscitation, and was carried out in a high dependency unit setting. At follow-up 3 months after discharge, the patient was well with no residual symptoms off all treatment. During the events of this case, it became apparent that while ear, nose and throat and infectious diseases team members were relatively familiar with the condition, other departments including the critical care team were less so.

A Psittacosis Outbreak among English Office Workers with Little or No Contact with Birds, August 2015.

INTRODUCTION: On 14th August 2015 an office manager informed Public Health England of five employees known to have been diagnosed with pneumonia over the previous three weeks. We investigated to establish whether an outbreak occurred and to identify and control the source of infection. METHODS: We undertook case finding for self-reported pneumonia cases at local businesses (July-August 2015). Clinical samples from a hospitalised case were tested for common respiratory pathogens, but returned negative results. Further testing confirmed Chlamydia psittaci infection in this case (serology and PCR).  We subsequently undertook C. psittaci testing for all cases, redefining them as confirmed (C. psittaci PCR or high antibody titre via serology) or probable (inconclusive C. psittaci serology). Twenty-eight day exposure histories informed descriptive epidemiological analysis. We conducted an environmental investigation at the office to identify potential sources of exposure. RESULTS: We identified six office workers with pneumonia; four met case definitions (three confirmed, one probable) with symptom onset between 29th July and 4th August 2015. Workplace was the only epidemiological link and only one case reported limited, indirect bird contact. Environmental investigations identified pigeons roosting near the office which were being fed by workers (none cases). DISCUSSION: This was a probable outbreak of psittacosis with no direct bird-to-human contact reported. Cases recovered after receiving appropriate antibiotics. Feeding of pigeons was stopped. A deep clean of office ventilation systems was conducted and workers were advised to avoid bird contact.  We hypothesised that indirect environmental exposure to infected pigeons was to the source of this outbreak. This work provides evidence that health professionals should consider psittacosis in the differential diagnosis of cases of severe or atypical respiratory illness even without overt bird contact.
