A patient is presented who had bilateral abductor vocal fold paralysis pathologically proven to be due to multiple system atrophy (MSA) in the absence of other neurological features. MSA is a degenerative neurological condition that includes olivopontocerebellar atrophy, Shy-Drager syndrome and striatonigral degeneration. The usual predominant features of MSA are cerebellar ataxia, autonomic dysfunction and Parkinsonism. Stridor is present in over one third of patients and has been reported previously as a presenting symptom in MSA: however previously reported patients have always gone on to develop other neurological symptoms. The usual investigations of bilateral abductor vocal fold paralysis caused by MSA will not reveal the pathological process and we believe that magnetic resonance imaging (MRI) of the medulla and brain stem and autonomic function tests are probably the investigations of choice. It is a worthwhile exercise attempting to identify MSA as the cause of stridor as the prognosis is good in the medium term if appropriate support is offered.

Between 1991 and 1993, 13 children (25 hearing ears) underwent recordings of the auditory brain stem response (ABR) under a general anaesthetic. The anaesthetic technique was similar for each child. Fourteen of these ears had fluid aspirated after myringotomy with insertion of grommets prior to the auditory brain stem response investigation. On subsequent hearing assessment six of these 14 ears (43 per cent) showed clear evidence of a threshold shift of 15 dB or greater. Eleven ears had either dry myringotomies or did not have a myringotomy prior to ABR and none of these showed evidence of a temporary threshold shift. Using Fisher's Exact probability test this difference is significant (p = 0.034). We feel it is important to report these observations so that unexpected high ABR thresholds following aspiration of glue are interpreted with caution.

This paper reports the case of a six-week-old infant who presented with severe rhinitis and upper airway obstruction due to infection with Chlamydia trachomatis.

We report a case of persistent epistaxis in a seven-month-old child with Wilms' tumour who had an associated von Willebrand's type bleeding diathesis. Correction of the bleeding diathesis to control the epistaxis required treatment of the tumour with chemotherapy.

Tracheostomy has, in the past, been performed in the majority of children under one year with bilateral vocal fold paralysis. We present our experience of 11 cases over a ten-year period during which tracheostomy was avoided whenever possible. Ten cases were managed conservatively but in the youngest a tracheostomy was required. Full bilateral vocal fold mobility developed in all cases at a mean age of 11.5 months (range 5–26 months). Our experience suggests that the airway can commonly be managed expectantly without a tracheostomy.

Munchausen syndrome by proxy (MSBP) is a rare condition in which a parent or guardian fabricates an illness in a child either by inducing physical signs or prevaricating. A case presenting as recurrent episodes of infant apnoea is reported. A high index of suspicion is required for the diagnosis and, therefore, the otolaryngologist must be familiar with the condition if the life of the infant is to be protected and potentially harmful unnecessary investigations are to beavoided.

Isolated nasopharyngeal tuberculosis is a rare disease with very few cases having been reported in recent years. We report a case presenting in the United Kingdom with unilateral otalgia and otorrhoea.

Premature cartilaginous calcification and nasal hypoplasia following first trimester exposure to warfarin are known as the Foetal Warfarin Syndrome (FWS). There are over 40 cases reported in the literature, many of which describe breathing and feeding difficulties in the first few months of life. We report a case where a child had had difficulties breathing and feeding in the first months of life. These had been attributed to nasal hypoplasia. After proper ENT assessment the child benefitted from adenoidectomy.

ENT surgeons should be aware of the syndrome as more women of child bearing age are taking warfarin following cardiac surgery and treatment of thromboembolic disease. ENT surgeons may be asked to review these children who often present with airway and feeding problems which have been attributed to nasal hypoplasia.

The first case of an inhaled Montgomery Safe T-tube plug is reported. Both the surgeon and the patient should be aware of this possible complication and regular inspection of the plug is recommended. More than one plug should be provided with each T-tube.
