Management of paediatric otogenic cerebral venous sinus thrombosis: a systematic review.

BACKGROUND: Otogenic paediatric cerebral venous sinus thrombosis (CVST) is rare but has potential clinical sequelae. Its management has long been debated mainly concerning the role of surgery and the use of anticoagulant therapy. OBJECTIVE OF REVIEW: To review the current literature and examine the medical and surgical management of paediatric otogenic CVST and its clinical and radiological outcome. TYPE OF REVIEW: Systematic review. SEARCH STRATEGY: The electronic databases (MEDLINE, EMBASE, Cochrane) were searched from inception to November 2014 using text words 'cerebral venous sinus thrombosis OR cerebral venous thrombosis OR lateral sinus thrombosis OR sigmoid sinus thrombosis' AND 'otogenic OR mastoiditis OR otitis media' AND 'children OR paediatric OR pediatric'. EVALUATION METHOD: Inclusion criteria were applied by two reviewers and data extraction was carried out. The type of otological surgery (conservative versus extensive) and the use of anticoagulants with their clinical and radiological outcomes were tabulated. RESULTS: Thirty-six studies (15 case reports and 21 case series) were included with a total of 190 patients. A total of 92.1% of patients underwent otological surgery, and 69.5% had conservative surgery and 30.5% extensive otological surgery. Anticoagulants were used in 59%. A total of 79.2% of patients were reported to have had a good clinical outcome. Within this group, 56% had conservative surgery and anticoagulants. Follow-up scans were documented in 61.6% of patients and complete recanalisation was observed in 51%. Complete recanalisation was observed in 47% of those who had been anticoagulated and 55% of those who received no anticoagulation. CONCLUSIONS: Conservative otological surgery with the combination of anticoagulation was the most common treatment modality found in the group of patients with good clinical outcome. However, given the current low level of evidence, a multicentre collaborative study is needed to help establish the optimum surgical approach and the role of anticoagulation in managing paediatric otogenic CVST.

A rare case of spontaneous thyroid cyst haemorrhage.

BACKGROUND: We report a case of hypopharyngeal swelling secondary to a spontaneous thyroid cyst haemorrhage. Haemorrhage is a known complication of thyroid cysts, and usually presents as external swelling and localised pain. CASE REPORT: A 93-year-old woman developed hypopharyngeal swelling, dysphagia and odynophagia. A computed tomography scan was consistent with thyroid cyst haemorrhage. The patient was treated with needle aspiration and intravenous steroid injections, with full recovery at thyroid clinic review. CONCLUSION: To our best knowledge, there has been no previous report of a hypopharyngeal swelling occurring secondary to spontaneous thyroid cyst haemorrhage. Our case is unusual because of the risk of airway compromise at the level of the hypopharynx, secondary to thyroid cyst haemorrhage.

Night emergency cover for ENT in England: a national survey.

OBJECTIVES: To evaluate the quality of out-of-hours ENT on-call cover by junior doctors, in view of the European Working Time Directive and the recent changes in the National Health Service workforce due to the 'Modernising Medical Careers' initiative, in England. METHODS: We performed a national survey of first-on-call doctors for ENT, using a telephone questionnaire. Hospital contact details were sourced from the National Health Service website. The inclusion criterion was hospitals providing acute ENT facilities overnight in England. RESULTS: One hundred and nineteen hospitals were contacted; 91 were eligible, and 83 interviews were conducted. The grade of the first-on-call ENT doctor ranged from foundation year two (19 per cent) to registrar level or above (13 per cent). Forty-nine respondents (68 per cent) reported having no previous ENT experience. Fifty-three respondents (74 per cent) covered more than one speciality at night, with seven (10 per cent) covering four or more specialities. The second-on-call doctor was non-resident in 63 cases (88 per cent). Thirty respondents (42 per cent) stated that they did not feel comfortable managing common ENT emergencies as the first doctor on call. Otorhinolaryngology induction courses were offered in 37 of the respondents' hospitals (51 per cent), these courses were of varying duration. CONCLUSION: Night-time ENT care is often provided by junior doctors with little experience of the speciality, who are often also responsible for covering multiple specialities. Many reported not feeling comfortable managing common ENT emergencies. Structured induction programmes would help to provide basic knowledge and should be mandatory for all doctors covering ENT.

Infection rates after tympanostomy tube insertion, comparing Aboriginal and non-Aboriginal children in the Northern Territory, Australia: a retrospective, comparative study.

OBJECTIVE: To determine if there is a difference in infection rates between Aboriginal and non-Aboriginal children, following tympanostomy and ventilation tube placement, in the Northern Territory, Australia. MATERIALS AND METHODS: A cohort of 213 patients aged zero to 10 years who had undergone tympanostomy and ventilation tube placement at the Royal Darwin Hospital between 1996 and 2004 were identified. Patients were divided into Aboriginal or non-Aboriginal groups, from their medical record. Factors such as age, sex, dwelling (remote or urban) and season were compared for each group, in order to ascertain if they contributed to infection rates. A retrospective analysis of cases was conducted for the two-year post-operative period. RESULTS: There was no statistically significant difference in infection rates between the two groups (37 vs 35 per cent). There was no statistically significant difference when comparing the two groups for age, sex, season, or remote vs urban dwelling. CONCLUSION: Aboriginal children were not prone to more infections following tympanostomy tube placement when compared with non-Aboriginal children.

The quality of operative note taking: an audit using the Royal College of Surgeons Guidelines as the gold standard.

To assess the quality of operative note keeping and compare the results with the Royal College of Surgeons (RCS) of England guidelines 'Good Surgical Practice' as the gold standard. ENT Department at Hull Royal Infirmary, University Hospital. A hundred consecutive operative notes were selected between November 2005 and January 2006. The documentation of the operative notes in each case was compared with the RCS of England guidelines. All surgeons were made aware of the results of the first cycle and the guidelines were made available in all ENT theatres in the form of a printed aide-memoir. A second audit cycle was then carried out prospectively between April and June 2006. The results demonstrated a change in practice in key areas. The 1st cycle results showed the documentation of patient identification (94%), name of surgeon (98%) and clearly written postoperative instructions (94%). However, surgeons performed suboptimally at recording the name of assistant (82%), operative diagnosis (46%), the incision type (87%) and the type of wound closure (83%). After introducing the aide-memoir, the second cycle demonstrated a change in practice with 100% documentation in most of the assessed parameters except that the time of surgery and the type of surgery (emergency or elective) were not adequately recorded. We recommend that all surgical departments should have the RCS guidelines as an aide-memoir in theatres to enhance the quality and standardise operative note recording.

Heterotopic gastric mucosa in the cervical oesophagus (inlet patch) and globus pharyngeus--an under-recognised association.

Globus pharyngeus is a symptom commonly encountered in ENT practice. The usual complaint is that of the sensation of a ball or lump in the throat generally unaccompanied by dysphagia. This sensation is often more pronounced when taking an 'empty swallow'. The precise mechanism of this remains enigmatic in many cases. Irritant factors such as gastroesophageal reflux, postnasal drip and excessive throat clearing may be contributory factors as may be stress and psychological influences. Although gastric type mucosa occupying the cervical oesophagus has been long recognised, mainly in the specialised gastrointestinal literature, there appears to be more limited awareness of the condition in ENT practice and the clinical significance of such heterotopia is not well established. We present five recent cases of globus pharyngeus encountered in our ENT practice in which rigid pharyngoesophagoscopy and biopsy revealed heterotopic gastric mucosa within the postcricoid and cervical oesophagus constituting a so-called gastric 'inlet patch'. One case re-presented with invasive adenocarcinoma within a short time. Herein we compare and contrast inlet patch with columnar lined oesophagus, discuss the potential clinical significance of inlet patch and comment upon further management of the condition.

Otic drops used to clear a blocked grommet: an in vitro prospective randomized controlled study with blinded assessment.

Clinicians often prescribe otic drops anecdotally to try and clear grommets blocked with blood. We carried out an in vitro double-blind randomized controlled study comparing the efficacy of sodium bicarbonate, Locorten Vioform and olive oil drops in clearing Shah grommets placed in 'artificial ears' and blocked with blood in a standardized fashion. There were 33 grommets in each group, and drops were inserted three times a day for 7 days. Olive oil drops cleared 17 of 33 (51.51%), Locorten Vioform cleared one of 33 (3%) and sodium bicarbonate cleared zero of 33 (0%) blocked grommets. Statistical comparison between pairs indicates that olive oil was significantly better than both Locorten Vioform (P < 0.001) and sodium bicarbonate drops (P < 0.001) at clearing grommets blocked with blood.

Long-term ventilation of the middle ear using a subannular tympanotomy technique: a follow-up study.

The results of a nine-year series of patients who underwent long-term middle ear ventilation using a tympanotomy technique are presented. The original series of 26 cases was published in 1995. The same series has now expanded to 37 cases, which form the basis of this follow-up study. In contrast to the original series we found a high spontaneous extrusion rate (68 per cent) and in 27 per cent of cases complications necessitated removal of the subannular T tube. In favour of the technique was a low perforation rate after extrusion or removal (eight per cent). Although only nine per cent underwent re-ventilation this is unlikely to represent resolution of the middle ear effusion in the remaining cases. We conclude that the adverse effects of the subannular tympanotomy technique for long-term ventilation of the middle ear outweigh the benefits when compared with the traditional technique of placing a T tube through a myringotomy incision.

Does flying after myringoplasty affect graft take rates?

Flying at altitude soon after myringoplasty may theoretically have an adverse effect on graft take rates owing to variation in external air pressure, together with suboptimal Eustachian tube function, causing graft displacement. We wished to assess the effect of flying after myringoplasty by comparing success rates of patients flying within a week postoperatively (n = 37) with a control group (n = 37) by carrying out a retrospective, controlled cohort study. The primary outcome measure was graft success, defined as a 100% closure at first outpatient follow-up (2.5 months). Our results showed that there was no difference in early graft success rates between the flying group (32/37: 86%) and non-flying group (29/37: 78%)(P = 0.32; 95% CI of difference: -9% to 27%). In conclusion, flying at altitude in a pressurized environment within a week of myringoplasty does not adversely affect early operative success.

The effect of hypertonicity on nasal mucociliary clearance.

The effect of the tonicity of saline nasal douching solutions on mucociliary clearance was studied in order to ascertain whether hypertonicity conferred any advantage. Thirty-eight normal subjects were included in a randomised double-blind crossover trial. Saline douching solutions of 0.9%, 3% and 5% tonicity were used and mucociliary clearance was measured by the saccharin clearance time (SCT). The resultant SCT after administration of 5% saline was significantly reduced compared to both 0.9% (P = 0.005) and 3% saline (P = 0.04). There was no difference between 0.9% and 3% saline administration. Thus hypertonic saline solutions improve mucociliary clearance, although this was only observed with solutions of 5% tonicity. The effect is probably brought about by changes in mucus rheology.

Z-meatoplasty technique in endaural approach mastoidectomy.

Creating an adequate meatoplasty is an important and integral part of a mastoidectomy. It allows ventilation of the ear canal but also provides for an easy access for visualizing and cleaning the mastoid cavity. There are numerous techniques for performing a meatoplasty. We describe our method of utilizing the endaural incision and superiorly based tympanomeatal flap incision to create an easy and effective Z-meatoplasty.

Base of tongue varices associated with portal hypertension.

A symptomatic case of tongue base varices in a patient with portal hypertension secondary to liver cirrhosis is presented. There are no previously documented cases in the world literature. Oesophageal varices may not be the only source of expectorated blood in a patient with portal hypertension.

Pleomorphic adenoma of the nasal septum.

Pleomorphic adenoma is the commonest benign tumour of the major salivary glands. It can also occur in minor salivary glands, mainly in the oral cavity, but also in other sites in the head and neck both within and outwith the upper aerodigestive tract. We present a rare case of pleomorphic adenoma of the nasal septum with consideration of the clinical management and a review of the literature.

The use of toluidine blue gargles to aid the detection of impacted pharyngeal fish bones.

Fishbone impaction is a common clinical problem. In most cases careful examination pinpoints the impacted bone which can then be removed. If no bone is detected a distinction must be drawn between mucosal abrasion mimicking fishbone impaction and a fine or deeply impaled fishbone eluding detection. We present a new method that may be helpful in the detection of pharyngeal fishbones.

Recurrent unilateral tonsillitis secondary to a penetrating foreign body in the tonsil.

We report a case of an impacted foreign body in the tonsil presenting as recurrent unilateral tonsillitis. A completely embedded foreign body should be considered in cases of recurrent unilateral tonsillitis.

A case of intractable epistaxis.

The surgical management of intractable epistaxis by external carotid artery ligation may become complicated if there is a high bifurcation of the common carotid artery. Occlusion of the bleeding vessels by catheter embolization is described in a patient in whom exploration of the neck had failed to locate the external carotid artery.

AIDS education in rural Uganda--a way forward.

A survey of acquired immunodeficiency syndrome (AIDS)-related knowledge and attitudes was conducted during July and August 1988 in rural SW Uganda. The aim was to assess the impact of Uganda's AIDS education programme and to consider how future programmes could be more effectively implemented. Four hundred and seventy-six individuals aged 12-45 years were selected by a quota method, to form a sample stratified by age and sex. Mass AIDS education has successfully raised levels of knowledge but misconceptions persist. However, it has failed, firstly, to stress the urgency of AIDS as a personal issue, and secondly, to change negative attitudes toward people with AIDS: 57% would avoid or stigmatise an individual with AIDS. Unexpectedly, findings show that a correlation exists (P less than 0.05) between high levels of 'correct' beliefs and negative attitudes toward people with AIDS. To achieve future behavioural and attitude changes, possible ways forward for Ugandan AIDS education include involvement of HIV carriers in education, small-scale targetted approaches developed by active participation of the target group and through role playing of people with AIDS.
