Alcohol levels in the emergency department: a worrying trend.

BACKGROUND: Recent tabloid media articles have highlighted the trend of increasing alcohol intoxication among the young, particularly females. We compared all the alcohol levels sent from the emergency department of Belfast City Hospital over two 12-month periods, 4 years apart, to see if there were any changes in the pattern of levels or numbers of tests sent. METHODS: Patient details and alcohol levels for the periods 1 September 1999 to 31 August 2000 and 1 September 2003 to 31 August 2004 were obtained from our laboratories and entered into a database. RESULTS: The number of patients with blood alcohol levels > 80 mg/100 ml rose from 526 to 1124, a rise of 113%. The number of patients with levels > 480 mg/100 ml rose from five to 29, a rise of 480%. There were more intoxicated males in every age bracket in both study periods apart from under the age of 16, in which females were in the majority. The absolute number of intoxicated females almost doubled from 203 to 401. The proportion of females in both study periods, however, was similar--38.6% and 35.7%, respectively. CONCLUSION: These results show a trend towards more intoxicated people presenting to the emergency department of Belfast City Hospital. Males continue to account for the majority of intoxicated patients.

The mediastinum--is it wide?

OBJECTIVE: To determine if the 8 cm upper limit for mediastinal width applies in the trauma setting of today. To define the upper limit of normal mediastinal width for supine chest films. METHODS: A retrospective review of chest computed tomography scans was conducted to determine the width and position of the mediastinum within the supine chest. Radiographs were performed using a model that enabled the degree of mediastinal magnification to be ascertained in a variety of clinical settings. RESULTS: The mean mediastinal width is 6.31 cm. With standard radiographical techniques this mediastinum is magnified to 8.93-10.07 cm. With minor adaptations in radiographical technique this can be reduced to 7.31-7.92 cm. CONCLUSION: The 8 cm upper limit for normal mediastinal width, set in the 1970s does not apply in the modern trauma room. Changes in the position of the x ray cassette, and lengthening of the distance between the patient and the x ray source will significantly reduce magnification. A new range of upper limits is defined for the radiographical techniques possible in different trauma settings.

Markers for domestic violence in women.

OBJECTIVE: To determine injury patterns and characteristics specific to domestic violence in women who present to the accident and emergency (A&E) department. DESIGN: A retrospective case note review of all female assaults over a one year period. The subjects were women who disclosed that their injuries were due to assaults by either a current or a previous male partner. Controls were female assault victims not injured by domestic violence. SETTING: A medium sized urban A&E department. RESULTS: There were 500 female assaults out of 48,169 new attendances. Domestic violence was disclosed in 103 cases. The following features were significantly associated with domestic violence in women: multiple injuries (p < 0.001) (especially to the head and arms), fractures (p < 0.05), loss of consciousness (p < 0.05), abdominal injuries (p < 0.05), pregnancy (p = 0.01), injury occurring on "stairs" (p = 0.01), and general practitioner referral (p < 0.01). CONCLUSIONS: Women who have been assaulted are more likely to have been injured during domestic violence if they sustain multiple injuries (including fractures), abdominal injuries, have lost consciousness, or have been referred by their general practitioner. These markers may help medical staff to identify more cases of undisclosed domestic violence. The markers need to be tested further in a prospective study.

Who gives pain relief to children?

OBJECTIVE: To compare pre-hospital parental administration of pain relief for children with that of the accident and emergency (A&E) department staff and to ascertain the reason why pre-hospital analgesia is not being given. DESIGN/METHODS: An anonymous prospective questionnaire was given to parents/guardians of children < 17 years. The children were all self referred with head injuries or limb problems including burns. The first part asked for details of pain relief before attendance in the A&E department. The second part of the questionnaire contained a section for the examining doctor and triage nurse to fill in. The duration of the survey was 28 days. RESULTS: Altogether 203 of 276 (74%) of children did not receive pain relief before attendance at the A&E department. Reasons for parents not giving pain relief included 57/203 (28%) who thought that giving painkillers would be harmful; 43/203 (21%) who did not give painkillers because the accident did not happen at home; and 15/203 (7%) who thought analgesia was the responsibility of the hospital. Eighty eight of the 276 (32%) did not have any painkillers, suitable for children, at home. A&E staff administered pain relief in 189/276 (68%). CONCLUSIONS: Parents often do not give their children pain relief before attending the A&E department. Parents think that giving painkillers may be harmful and often do not have simple analgesics at home. Some parents do not perceive that their child is in pain. Parents require education about appropriate pre-hospital pain relief for their children.

Public knowledge of dental registration and management of common dental problems.

The government has recently changed its policy on dental registration. There is now a requirement to attend a dentist within 15 months of the previous appointment or dental registration will lapse. The authors of this article undertook a survey of the patients attending for dental treatment at the accident and emergency department of their hospital to ascertain whether inappropriate attendance was due to ignorance about general dental services. Of the 501 respondents 14% had not seen their general dental practitioner within the last 15 months and were therefore no longer registered--only 21% realized that they had to keep regular appointments or dental registration would lapse. A proportion (30%) had tried to contact the dentist outside normal working hours; 27% of these were unhappy with the outcome. Telephone calls were unanswered in 38% of those expressing dissatisfaction and 45% subsequently attended hospital for treatment.

Can x rays be accurately interpreted using a low cost telemedicine system?

OBJECTIVE: To assess whether the quality of x ray films transmitted via a low cost (low resolution) telemedicine link was satisfactory for clinical diagnosis. METHODS: A retrospective study of a set of consecutive accident and emergency (A&E) radiographs. An A&E registrar viewed these directly on a standard x ray viewing box and via a telemedicine link. RESULTS: There were 81 abnormalities out of 234 x ray films. Three abnormalities were missed both on the x ray viewing box and telemedicine link, one of which was significant. There were five additional abnormalities missed on the telemedicine link but detected on the x ray viewing box, of which two were significant. One normal x ray film was interpreted as abnormal on the telemedicine link. There were no false positives on direct viewing. CONCLUSION: Transference of plain radiographs using a low cost/low resolution telemedicine link by A&E doctors is adequate for clinical interpretation.

Notification of infectious diseases by junior doctors in accident and emergency departments.

OBJECTIVE: To assess the knowledge about notifiable infectious diseases by accident and emergency (A&E) senior house officers. METHODS: A telephone questionnaire of senior house officers was carried out over a one week period at the end of their six month attachment in A&E departments in Northern Ireland. RESULTS: 81 (91%) of the senior house officers participated in the study; 23 (29%) realised that the doctor diagnosing the notifiable disease had a statutory duty to notify that disease; nine (11%) were aware there were three statutory lists in the United Kingdom. Knowledge about which infectious diseases require notification varied from 79/81 (98%) for meningococcal disease to 15/91 (19%) for methicillin resistant S aureus. Seventy nine (98%) of the doctors thought that a poster displayed in the A&E department would be helpful. There was no significant difference between duration of qualification and performance on the questionnaire (p = 0.2). CONCLUSIONS: Despite varying experience, junior doctors in A&E do not know which infectious diseases are notifiable by statute. They felt that it would be helpful to have a poster in the A&E department listing the notifiable diseases of that region. To encourage accurate reporting, interregional variation between the statutory lists should be abolished and replaced by one nationally agreed list.

Severe hypercalcaemia four months after acute oliguric renal failure--successful treatment with intravenous clodronate.

A 33 year old man developed acute oliguric failure lasting 66 days, eight days after admission with multiple gun shot wounds. On day 99 after admission, serum calcium was elevated mildly at 2.54 mmol/l (normal range 2.1-2.5 mmol/l). Serum parathormone was undetectable. He was discharged soon afterwards. He presented again on day 164 with nausea, vomiting and blurred vision. Fundoscopy revealed an ischaemic retinopathy and extensive keratopathy. Serum calcium was 3.48 mmol/l and serum creatinine 262 umol/l (normal range 40-110 umol/l). Repeat parathormone was undetectable and there was no evidence of myeloma, sarcoidosis or malignancy. Following treatment with intravenous saline and frusemide, serum calcium fell to a nadir of 3.05 mmol/l. On day 168 an infusion of sodium clodronate 300 mg was given. Twenty-four hours later serum calcium was 2.65 mmol/l and 48 hours later calcium was 2.26 mmol/l. Normocalcaemia was maintained for 17 days and severe hypercalcaemia never recurred. This is the first report in which biphosphonates have been successfully used to treat hypercalcaemia following acute renal failure thus obviating the need for further dialysis.

Space management required after unsuccessful root canal therapy of a mandibular second primary molar: case report.

Root canal therapy for primary molars is not always successful. This report illustrates that the consequences of treatment can be significant in terms of patient discomfort, loss of arch circumference, expense to the parent, the amount of time needed to accomplish the clinical objective, and the commitment to long term follow-up care.

The influence of tooth preparation and crown manipulation on the mechanical retention of stainless steel crowns.

The belief that close adaptation of the metal margins to tooth surfaces in the undercut areas is the most important retentive feature, was borne out in this study. The type of preparation did not affect the retention of stainless steel crowns.

Incomplete resorption of resorbable zinc oxide root canal fillings in primary teeth: report of two cases.

Two cases in which all of the zinc oxide canal filling did not resorb are described. The histories emphasize the importance of careful monitoring of treated primary teeth. The cases described were monitored for more than five years.

Two principles for improving the adaptation of stainless steel crowns to primary molars.

Two principles are discussed that address the length and marginal contours of stainless steel crowns. Application of morphologic findings of teeth and contours of marginal gingival tissues are presented to support these principles. Clinical applications of these principles are discussed. Use of them in your technique will enhance the efficient adaptation of stainless steel crowns. In fact, you will be more efficient with guesswork eliminated. Also, incorporation of the principles into your technique will ensure that the efforts you make will result in the adaptation of custom stainless steel crowns for your patients.
