A 26-year-old woman presenting for an elective day case procedure under general anaesthesia had undiagnosed subglottic stenosis leading to a life threatening airway emergency requiring emergency front-of-neck airway. We outline the case and discuss key anaesthetic considerations in subglottic stenosis, including concerning features of a medical/anaesthetic history and the potential for rapid deterioration of a stenotic airway following manipulation. We also consider the effect of anaesthesia on the calibre of subglottic stenosis and the effects of positive pressure ventilation. Subglottic stenosis is a rare condition with congenital, acquired and idiopathic origins; however, iatrogenic trauma is the most common cause. We are aware of a small number of published case reports of previously undiagnosed subglottic stenosis in adults discovered after induction of anaesthesia; situational deterioration to 'cannot intubate, cannot oxygenate' scenarios appear even rarer.

We compared lower limb coronal alignment measurements obtained pre- and post-operatively with long-leg radiographs and computer navigation in patients undergoing primary total knee replacement (TKR). A series of 185 patients had their pre- and post-implant radiological and computer-navigation system measurements of coronal alignment compared using the Bland-Altman method. The study included 81 men and 104 women with a mean age of 68.5 years (32 to 87) and a mean body mass index of 31.7 kg/m2(19 to 49). Pre-implant Bland–Altman limits of agreement were -9.4° to 8.6° with a repeatability coefficient of 9.0°. The Bland–Altman plot showed a tendency for the radiological measurement to indicate a higher level of pre-operative deformity than the corresponding navigation measurement. Post-implant limits of agreement were -5.0° to 5.4° with a repeatability coefficient of 5.2°. The tendency for valgus knees to have greater deformity on the radiograph was still seen, but was weaker for varus knees.The alignment seen or measured intra-operatively during TKR is not necessarily the same as the deformity seen on a standing long-leg radiograph either pre- or post-operatively. Further investigation into the effect of weight-bearing and surgical exposure of the joint on the mechanical femorotibial angle is required to enable the most appropriate intra-operative alignment to be selected.

Acute compartment syndrome has a multitude of aetiologies. Unfortunately, the diagnosis is often delayed, resulting in permanent functional loss. Although spontaneous muscle infarction is an uncommon, yet well-recognized complication of diabetes mellitus, subsequent development of compartment syndrome appears to be rare, with only five case reports identified in the literature. This condition has not been reported in the emergency medicine literature. We report a case of a diabetic gentleman who presented with lower limb pain significantly out of proportion to any obvious injury and had a subsequent diagnosis of acute compartment syndrome. Despite fasciotomies, he had a persistent foot drop. Nontraumatic acute compartment syndrome secondary to diabetic muscle infarction should be considered in any diabetic patient presenting with pain out of proportion to sustained injury.

Anterior cervical spine fusion and stabilization is a well-recognized procedure for a number of cervical spine disorders. Unfortunately, the complex anatomy of the cervical spine means that these procedures are not without complications. Pharyngo-oesophageal perforation is a rare but potentially life-threatening complication of cervical spine surgery and may present intra-operatively, in the immediate post-operative period or many years later. We present the case of a gentleman with ankylosing spondylitis who presented with a pharyngeal perforation and fistula five years after cervical spine surgery.

Objective: To audit sore throat management in adults, introduce proforma-based guidelines and to reaudit clinical practice.Setting: Adult emergency department of an inner city teaching hospital.Methods: A literature search was carried out to identify relevant guidelines. In stage one, patients presenting to the emergency department with sore throat were identified retrospectively from the emergency department attendance register. Proformas were completed retrospectively. In stage two, new guidelines were introduced and staff educated about the guidelines. In stage three, patients presenting with sore throat were identified at triage and proformas were completed at time of consultation.Outcome Measures: (1) appropriate clinical assessment of the likelihood of bacterial infection using the clinical scoring system, (2) appropriateness of antibiotic prescription, (3) recommendation of supportive treatments to patients.Results: Introduction of a clinical scoring system reduced the inappropriate prescribing of antibiotics from 44 per cent to 11 per cent. Correct antibiotic prescription rose from 60 per cent to 100 per cent. Although the variety of advice given about supportive treatment increased, the actual number of patients receiving documented supportive advice fell from 67.8 per cent in stage one to 58 per cent in stage three.Conclusion: The introduction of clinically based guidelines for the diagnosis and management of sore throat in adults can reduce inappropriate antibiotic prescribing.

Aims: To determine whether guidelines relating to the diagnosis and treatment of acute otitis media (AOM) in children are followed in a tertiary paediatric emergency department (ED).Methods: A literature search was undertaken to identify national and international guidelines relating to the diagnosis and management of AOM in children. The guidelines were assessed for their applicability to UK practice. A retrospective case note audit was undertaken. Children presenting to the ED with a discharge diagnosis of AOM over a two month period were identified from the ED computer discharge system. The notes were analysed for compliance with the identified guidelines.Results: 50 children were identified (age range three months to 11 years). Eighty-six per cent of children received antibiotics. Fifty-two per cent of children had documented signs of AOM. Twenty-five of these children received antibiotics (22 in accordance with guidelines, three not in accordance with guidelines, antibiotic not documented in one case). Thirty-nine per cent of children received antibiotics inappropriately. In all cases, the antibiotic dosage was below the dose recommended in all guidelines.Conclusion: There is poor compliance with national (and international) guidelines for the management of AOM in this ED. National guidelines must be introduced into the department by direct teaching at senior house officer and middle grade level, a re-audit must be carried out and regular reviews of the notes of patients diagnosed with AOM must be undertaken to ensure compliance with guidelines is maintained.

Meningococcal disease remains an important cause of mortality and morbidity in the paediatric population. Survivors of invasive meningococcal disease remain at risk from the long-term sequelae of microvascular disease. Chronic orthopaedic sequelae have been reported infrequently in the orthopaedic and radiology literature and there are no reports in the Emergency Medicine literature. We report the case of a 7-year-old boy who presented to the Emergency Department with a limp; having survived invasive meningococcal disease at the age of 14 months. His radiographs revealed some of the long-term sequelae of this severe disease. We review the literature around the long-term orthopaedic sequelae of meningococcal disease.

Objective:We report an adult case of cystic lymphangioma treated with OK-432 (Picibanil®).Method:A case report and review of the literature concerning the use of OK-432 to treat cystic lymphangioma is presented.Results:A 31-year-old woman developed a cystic lymphangioma four weeks post-partum. This was treated initially by aspiration, for diagnostic purposes. Investigation suggested that surgery would be challenging. A review of the literature demonstrated success with OK-432 in the treatment of this condition, although primarily in the paediatric population. This patient was successfully treated thus, and at the time of writing remained symptom free. A suggested management plan is outlined.Conclusion:Treatment with OK-432 is useful in the management of cystic lymphangiomas in adults and should be considered as first line treatment.

Objectives:To present a case of benign mediastinal thymic cyst, and to review the published information on these cysts, including their incidence, presentation, diagnosis and management.Methods:We report the case of a 55-year-old man who presented with a unilateral vocal fold palsy subsequently found to be due to the presence of a benign mediastinal thymic cyst. A literature search was undertaken to identify the incidence, key features and management of this rare condition.Results:Benign mediastinal thymic cysts are a rare cause of mediastinal masses. Usually diagnosed incidentally, their management is usually surgical. Vocal fold palsy in isolation has not previously been reported in association with mediastinal thymic cysts.Conclusion:This report describes what we believe to be the first published case of a completely reversible vocal fold palsy presenting in association with a rare benign mediastinal thymic cyst.

Surgical procedures in otolaryngology are often associated with the need for blood transfusions. Homologous blood transfusions carry risks and may be unacceptable to some patient groups. The Jehovah's Witness Society is known to many because of its stance on blood products. Refusal of potentially life-saving treatment creates ethical dilemmas for treating clinicians. Throughout the world, Jehovah's Witnesses have fought for the right to refuse blood products. This article examines the need for blood in otolaryngological procedures, surgical strategies to reduce blood loss, the beliefs of Jehovah's Witnesses regarding the acceptability of blood, and procedures and legal stances adopted when treating Jehovah's Witnesses.

Foreign body ingestion in children is a common presenting complaint to the emergency department. Although the majority of ingested foreign bodies pass through the gastrointestinal tract unaided, some children will require either non-surgical or surgical intervention. Retained oesophageal foreign bodies may cause a multitude of problems, including mucosal ulceration, inflammation or infection, and more seriously paraoesophageal or retropharyngeal abscess formation, mediastinitis, empyema, oesophageal perforation and aorta-oesophageal fistula formation. We present a case of a 12-month-old child in whom delayed diagnosis of glass ingestion resulted in the development of a retropharyngeal abscess, oesophageal perforation and mediastinitis. Such complications following foreign body ingestion in children are rare but potentially fatal. A high index of suspicion must be maintained in young children presenting with a possible history of foreign body ingestion as a delayed diagnosis may lead to significant morbidity and mortality. We review the literature surrounding paediatric retropharyngeal abscesses and mediastinitis.

Background: Crohn's disease (CD) is characterized by heterogeneity of phenotype. The Vienna classification can be used to classify CD, and recent data illustrate that behavior evolves over the course of the disease. Clinical and biological influences on disease progression remain unclear. We examined the associations of CD disease progression at diagnosis and for up to 20 years of follow-up. Methods: Two hundred thirty-one well-characterized CD patients were studied. Demographic, clinical, and NOD2/CARD15 data were collected. Disease behavior according to the Vienna classification was assessed at diagnosis and for up to 20 years following diagnosis. Results: At diagnosis, 70% of patients had inflammatory disease, 9% stricturing, and 21% penetrating. Early age at diagnosis was associated with ileocolonic and upper GI disease (p = 0.015), and positive anti-Saccharomyces cerevisiae antibody (ASCA) was associated with ileal invovement (p = 0.008). Smoking was relatively protective against colonic, rather than ileal involvement at diagnosis (p < 0.02). At 20 years, 92% had progressed to a more severe disease type. Patients who progress to a more severe disease type require more frequent surgery (p < 0.00001). Multivariate analysis found disease progression to be associated with ileal disease location (p = 0.001) and positive ASCA (p = 0.003). Variant NOD2/CARD15 alleles were protective against rapid progression of disease phenotype (p = 0.04). The presence of perianal disease was independent of intestinal penetrating disease. Conclusions: The progression of disease type in CD is associated with the need for more frequent surgery. Rapid progression is associated with ileal disease and positive ASCA, and delayed progression is associated with variant NOD2/CARD15 alleles. Consideration should be given to a separate Vienna classification for perianal disease.
