I read with interest the article by Yuen et al[1]. Anterior shoulder
dislocation accounts for a significant proportion of joint injury in
emergency medicine and any technique that improves our care for these
patients is to be welcomed.
The authors state that the technique is easily learned by senior house
officers and this certainly is important. Often the patient is seen by a
junior doctor when senior supervision may not be available so a safe, easy
technique is to be commended. We were concerned by the large numbers of
patients (57%) who required intravenous valium. We would advocate that
techniques that use no sedation or small amounts of NSAID or opiate are
safer for the senior house officer. Currently at Oxford we are using a
specially designed chair and back-rest to act as an external fulcrum in
the axilla. Gentle downward traction on the affected limb with external
rotation is then used to affect reduction. This is yielding an 85% success
rate without opiates or benzodiazepines[2]. Patient satisfaction is high
as their time in the department is minimised – typically less than 45
minutes from triage to discharge. The departments utilisation of staff is
improved since long term monitoring of the sedated patient is not needed.
No method offers 100% success and so operators need to be familiar with
alternatives.
Our second concern relates to biomechanics. The Spaso technique relies
primarily on traction and this is associated with inherent risks to soft
tissue structures. The literature is full of ‘easy techniques to reduce
anterior shoulder dislocation’[3]. We do not need yet another but should
consolidate our current practices to a safe approach to a common problem
in our Emergency Departments.

4) Do they explain the high levels as an intentional overdose, in which case did
he have mental health evalutaion when he woke up and were enquiries made about the possibility of deliberate self harm?
5) Did he have cardiovascular/ecg manifestations of phenytoin toxicity ?
The explanation you give for his seizures is phenytoin toxicity?
The evidence for this, based on just one level seemed to me a little too thin.

We thank Dr Kennedy for highlightning an unfortunate omission in our
review and we agree with his comments that carbon monoxide intoxications
are the most fatal reported poisoning in Western develloped countries.
Analgesics, which include acetaminophen, aspirin, and other nonsteroidal
antiinflammatory drugs are probably the leading cause of poisoning in
several countries. Paracetamol poisoning is very common in UK. In
Edinburgh, annual rate is reported as about 400/100,000 inhabitants [1].
It is responsible for 10% of calls to the National Poisons Information
Service Centre [2]. However, paracetamol poisoning in France accounts for
only 3.4% of all the medicamentous intoxications [3]i.e. an estimated
annual rate of 11.9/100,000 inhabitants.
The incidence of acute carbon monoxide intoxication (ACMI) varies
greatly from a country to another and from a region to another. In France,
the annual incidence of ACMI ranges from 10.04/100,000 [4] to 17.5/100,000 [5]. The real incidence is probably more important because ACMI is
underdiagnosed in about one-third of all cases [6].
In a region of Spain, the incidence of ACMI reached 76.5/100,000
inhabitants in 1992 and 109.4/1000,000 in the first half of 1993 [7].
In three states of the USA, ACMI is responsible for 52.9 cases per 100,000
Emergency Department (ED) visits. The annual rate is of 18.1 cases per
100,000 inhabitants [8]. Extrapoling these results to the US population
suggests that the number of individuals presenting at the ED for CO
intoxication is much greater than it is commonly reported. Hampson et al.
estimate that carbon monoxide poisoning produces 40,000 E.D. visits each
year in USA [8].
A retrospective study, in the West Midlands, from January 1988 to December
1994 reports an annual rate of CO poisoning of 3.9/100,000 [9].
As a conclusion, ACMI seems less frequent than analgesic intoxication
in United Kingdom but not in France. Once more, we agree with Kennedy's
comment that ACMI is the leading cause of death from poisoning in
developed countries.

The effects of sexual assault can be devastating; we commend Fong for
raising the profile of this topic within Accident and Emergency Medicine.[1] There are, however, a number of areas where we feel the guidance in that
paper could be improved. The data about HIV prevalence and risk groups
were out of date. We cite more recent data and guidance that may alter
readers' approach to this situation.

Up to the end of June 2001, there had been 46131 reported cases of
HIV infection in the United Kingdom.[2] The incidence of new HIV diagnoses
has increased each year since 1994. Since 1999 heterosexual intercourse
has been the commonest route of transmission.
Fong rightly emphasises that "HIV counselling and PEP is but one
aspect of the care and treatment of the rape victim". Although HIV
infection is especially worrying, sexual assault can lead to other
sexually transmitted infections and to (unwanted) pregnancy. Staff able to
diagnose and treat STIs and able to provide emergency contraception should
care for these patients. The optimum timing of testing for STIs is 10-14
days after the rape.
All anti-retroviral drugs can have significant side effects and
dangerous drug interactions. If it is felt that post-exposure prophylaxis
(PEP) might be needed, a suitably experienced clinician must be involved:
the most recent UK guidance states "after an exposure outside the health
care setting considered to carry a high risk of HIV infection, expert
advice should be sought urgently from a physician experienced in the
management if HIV and familiar with the considerations for the use of
PEP".[3] This guidance suggested that when starter packs were being
replaced they contain zidovudine, lamivudine and the protease inhibitor
nelfinavir (rather than indinavir, which is poorly tolerated because of
dietary restrictions needed when taking it). The guidance does not
recommend any two-drug regimen, nor does it mention a 72-hour window. It
states that PEP may be indicated up to 2 weeks after exposure.
All patients in whom HIV testing or PEP are considered require
adequate counselling. Physicians in Genito Urinary Medicine or HIV
Medicine will have more extensive experience in these areas than most
clinicians in Accident and Emergency Medicine; we feel the failure of the
review to suggest immediate referral to GUM or another specialty familiar
with HIV management is a major omission.
We strongly advise anyone working in the UK who is considering
providing PEP to first read the Expert Advisory Group on AIDS
recommendations.[3]

There has been considerable discussion recently about the best name
for the specialty currently called Accident and Emergency Medicine. Could
I suggest the specialty be renamed "Emergency and Trauma Care"? If this
name were adopted, both the name and the abbreviation would reflect the
nature of work undertaken by the specialty.
In the article by Greingor et al on carbon monoxide
poisoning in pregnancy, one word is
notably absent from the Discussion. I quote, with the word inserted,'CO intoxication is the most frequently reported (FATAL) poisoning in Western developed countries'. Most of us are aware that analgesic drugs are still the commonest intoxicating agent - are we not?
While I agree that the specialty in the UK should move to using the title
"Emergency Medicine" I would council that it may be difficult to gain
acceptance of the name amongst the wider community - both medical and non-
medical.

Medicine" since the Australasian College for Emergency Medicine was

Here in Australia, the specialty has been officially named "Emergency
Medicine" since the Australasian College for Emergency Medicine was
incorporated in 1984. However, this message has not permeated the wider
community. On a daily basis, I field letters and phone calls for "cas",
"casualty", A&E, to name but three of the most common names used. The
process of re-education begins as soon as the name change becomes official
– but obviously the effective timescale is an extended one.
Thus I would recommend that the name change be made as soon as possible –
and let the schooling process begin!

We thank Dr. T. Ho for his comment on our article reporting a young patient with tuberculous osteomyelitis [1]. We wrote the article from the perspective of emergency medicine. Although polymerase chain reaction (PCR) is a good adjunct to microbiological culture for diagnosing mycobacterium tuberculosis, it is not available to the majority of emergency physicians in Hong Kong. Nonetheless, we should discuss it briefly so that our article is more informative to readers.
Without argument, PCR provides an opportunity for early diagnosis and treatment. However, we should also note the limitation of the PCR especially when the PCR result is negative.
In 1998 Shah et al reported the accuracy of the AMPLICOR PCR test in diagnosing mycobacterium tuberculosis in tissue and body fluid specimens [2]. In this study, culture proof was adopted as the gold standard for diagnosing tuberculosis. Although 1032 patients were included in this study, only 34 specimens were positive for tuberculosis. Therefore, the sample size was too small and the 95% confidence interval of the sensitivity was too wide to suggest that PCR would not miss the diagnosis of mycobacterium tuberculosis. In this study, the PCR had a sensitivity of 76.4%, a specificity of 99.8% when results were compared with the gold standard. With the high specificity, PCR is a good "rule-in" test. However, PCR should not be used as a "rule-out" test because of the high false negative rate.
In 2000 Lim et al reported the accuracy of the AMPLICOR PCR test in diagnosing pulmonary tuberculosis in smear-negative respiratory tract specimens. Once again, the PCR test had a low sensitivity of 44% and a high specificity of 99% [3].
With evidence from both studies, a positive PCR test result facilitates early diagnosis, but a negative PCR test result cannot exclude mycobacterium tuberculosis. At the moment, microbiological culture remains the gold standard for diagnosing tuberculosis and a high index of suspicion for tuberculosis is the key to diagnosis.

Yuen and Tung describe a case of tuberculous osteomyelitis of the foot [1] and the potential difficulties in making the diagnosis. The authors were fortunate enough to have typical histological biopsy findings which subsequently cultured Mycobacterium tuberculosis (TB), providing diagnostic confirmation and estimations of sensitivities. However, in many instances, the diagnosis of tuberculosis is difficult to verify. For instance, acid fast bacilli may not be identified on biopsy or may be non-tuberculous in origin. Additionally, subsequent culture confirmation can take several weeks or may fail completely, due to TB's fastidious nature.
Although the reliance on clinical suspicion is the basis for the diagnosis of many cases of TB, definitive confirmation is desirable in view of the long-term nature of therapy. It is also important to ensure that the organism is not resistant to the chemotherapeutic regime being employed, particularly with the increasing incidence of multi-drug resistant TB strains. A number of novel diagnostic techniques have been developed to facilitate this. The use of the polymerase chain reaction (PCR) to amplify specific TB DNA sequences allows a rapid confirmation of the diagnosis and an estimation of drug sensitivity [2]. These techniques have been successfully used on both clinical specimens and culture material [3]. Thus, acid fast bacilli can rapidly be identified as Mycobacterium tuberculosis and an estimation of rifampicin sensitivity can be obtained in a matter of days, free from the contraints of waiting up to several weeks for the standard culture to grow. These techniques should therefore be considered, particularly if the clinical findings are subtle or atypical.

We are delighted that our paper [1] has stimulated a response from overseas colleagues, who have shared with us some Australasian opinions.
Whilst we agree that adopting the term 'emergency medicine' would bring us into line with international standard terminology, the fact remains that 'accident and emergency' appeals to many, and debate will continue as long as practice between and within United Kingdom departments varies so widely. For example, some accident and emergency consultants have greater experience in the management of patients with minor musculoskeletal injury - a major component of our workload - than in the resuscitation of critically ill medical patients. In addition a significant number of consultants draw private income from medicolegal reports, specialising in 'accidents', which at such a stage cannot be considered 'emergencies'. Such arguments have been put forward by our colleagues in support of retaining the word 'accident' in our title.
That terms such as 'Casualty' or 'Accident and Emergency' are derogatory is a matter of opinion. Of greater relevance is that disagreement continues not only over our name, but also regarding our specialty's key direction and consultants' future working patterns in a climate of increasing public demand, limited staffing and resources, and uncertainty over the future structure of emergency health care in the National Health Service. That is what makes emergency medicine such a fascinating specialty to be in, and the formation of a College of Emergency Medicine such a critical step in defining a unified direction for the specialty, whatever we in the United Kingdom finally agree to call it.
