Hutchinson's sign and its importance in rhinology.

Herpes zoster ophthalmicus usually has a typical appearance. However, if the disease is limited to the nasociliary branch of the trigeminal nerve, the ocular appearance may be confusing. Hutchinson in 1865 first noted that involvement of the external nasal branch of the fifth cranial nerve was associated with an increased incidence of ocular zoster. A case of herpes zoster ophthalmicus is presented that clinically resembled an ocular complication of sinus disease. The presence of a localized vesicular rash at the nasal tip assisted in an early diagnosis. Although this sign is known amongst ophthalmologists, its importance in rhinology is stressed. An anatomical explanation of Hutchinson's sign is given and the treatment of herpes zoster ophthalmicus is briefly discussed.

Patterns of hospital attendance with epistaxis.

The age and sex distribution of epistaxis admissions to hospital was examined. A retrospective analysis of 6,885 patients admitted to hospitals in the whole of Wales was performed, over a period of five years. The findings were compared with data from the 1991 National Population Census for the same region, thus providing a more representative estimate of the behaviour of this disease. A clear age relationship is demonstrated, with the incidence of epistaxis increasing rapidly after the age of 40 years. The female-to-male ratio is also age dependent. In the group aged between 20 to 49 years twice as many males as females were admitted, where no sex difference was expected from the population data. This difference was not present in the group aged 50 years and over where the ratio was similar to that in the underlying population. There was a 1.6 fold difference between the sex ratios of the two groups (95% confidence intervals of 1.9 to 1.4; p < 0.0001). It is possible that the female pre-menopausal state may provide a significant protection from this disease. The mechanism for this is unknown, but may be secondary to a direct effect of oestrogen on the nasal mucosa or vasculature, or the healing of vessels in this region. Alternatively, this observation may simply be a reflection of protection the pre-menopausal state provides against cardiovascular disease in general.

Tympanic thermometry and minor ear surgery.

Infra-red tympanic thermometry is a relatively new technique for measuring body temperature which requires the minimum of co-operation and is quick and easy to use. It is therefore ideal for use in children. Its use is becoming more widespread and as it is theoretically possible that minor ear surgery may interfere with function its reliability in these patients may be in question. Twenty-two children (mean age 5.3 years) who underwent myringotomy +/- grommet insertion had the tympanic temperature of each ear measured immediately before, and 15 minutes after, surgery on the recovery ward. No difference was found between the pre- and post-operative temperatures (mean difference--0.1 degree C, p > 0.1, paired t-test, hypothesized difference of 0). This thermometer appears to be a reliable way of monitoring body temperature on a paediatric ENT recovery ward in patients who have undergone minor ear surgery.

An unusual presentation of an encephalocele to the otolaryngologist.

An unusual case of encephalocele causing obstruction of the upper airway in a neonate is described. The patient presented with a large mass in the neck, which extended from the base of the skull to the level of the larynx. Although there was no evidence of a defect of the skull base, subsequent excision and histological examination confirmed an encephalocele.

Treatment of acute auricular haematoma.

Auricular haematoma is a problem frequently complicated by recurrence due to failure to apply adequate pressure over the pinna following simple drainage. We describe a simple method of splinting the pinna using silicone putty which overcomes this problem.

Acute angle closure glaucoma precipitated by intranasal application of cocaine.

We describe a patient who developed acute angle-closure glaucoma following the application of topical intranasal cocaine. A 46-year-old woman underwent an elective antral washout under general anaesthesia and with local application of 25 per cent cocaine paste to the nasal mucosa. Twenty-four hours post-operatively the patient developed sudden painful blindness which was found to be due to acute glaucoma. Cocaine with its indirect sympathomimetic activity causes mydriasis, that can precipitate acute angle-closure glaucoma in predisposed individuals with a shallow anterior chamber. Although the incidence is rare, otolaryngologists need to be aware of this potential complication.

Solitary plasmacytoma of the parotid gland.

Extramedullary plasmacytoma involving the parotid gland is a rare occurrence. This report describes a case of solitary extramedullary plasmacytoma arising from the parotid gland of a 60-year-old woman. The importance of thorough follow up for these patients is stressed, as the possibility of multiple myeloma is higher in this group.

Hospital epistaxis admission rate and ambient temperature.

The incidence of epistaxis admissions to hospital and their relationship to ambient temperature is examined. A retrospective analysis of 1211 patients with epistaxis sufficiently severe to warrant hospital admission was performed over a period of 1836 consecutive days. Daily average temperature data for this time-period were examined and compared with admission rates. A marked increase in hospital attendance was apparent during colder days. Patients were admitted at a rate of 0.829 patients per day for temperatures less than 5 degrees C, (95% Confidence Interval: 0.737-0.928), compared with 0.645 patients per day for temperatures between 5.1 and 10 degrees C, (95% 0.586-0.708). On average the population of epistaxis patients attended on days that were 0.6 degree C colder (95% Confidence Interval: 0.2 degree C-0.9 degree C) than the average temperature for the time examined (P < 0.005, student's t-test).

Pharyngocutaneous fistula following total laryngectomy and post-operative vomiting.

The significance of post-operative vomiting as a risk factor in the development of a pharyngocutaneous fistula was examined. The case records of 50 consecutive patients undergoing laryngectomies (39 men, 11 women, average age 64 years) were examined, 17 also underwent a simultaneous radical neck dissection. A fistula developed in eight patients (16%) and the median time to its diagnosis was 11 days (range 3-15 days). Several potential risk factors were examined including age, gender, previous radiotherapy, TNM stage, differentiation of tumour, simultaneous radical neck dissection and also the occurrence of vomiting post-operatively. In this series of patients only vomiting in the early post-operative period appeared to be related to the development of a fistula (regression summary: R2 = 0.6, t-value 5.6, P < 0.0001). An episode of vomiting was recorded in eight patients and of these six (75%) subsequently developed a fistula. The median time of post-operative vomiting was 7.5 days (range 1-10 days) and the diagnosis of a fistula occurred at a mean of 1.2 +/- 0.4 days after the episode of vomiting. In a study of this nature it is not possible to conclude that a causal relationship exists between vomiting and fistula development. However, if this is the case a potential means of decreasing the incidence of fistulae following laryngectomy may be available.
