OBJECTIVE: As one of Europe's most densely populated countries with multiple nuclear installations and a prominent petrochemical industry, Belgium is at some reasonable risk for terrorist attacks or accidental chemical, biological, radiation, and nuclear (CBRN) incidents. We hypothesize that local hospitals are not sufficiently prepared to deal with these incidents. MATERIALS AND METHODS: All 138 Belgian hospitals with an emergency department (ED) were sent a survey on their preparedness. Data on hospital disaster planning, risk perception, availability of decontamination units, personal protective equipment, antidotes, radiation detection, infectiologists, isolation measures, and staff training were collected. RESULTS: The response rate was 72%. Although 71% of hospitals reported being at risk for CBRN incidents, only 53% planned for the same in their disaster plans. Only 11% of hospitals had decontamination facilities in front of or at the ED entrance and only 6% had appropriate personal protective equipment for triage and decontaminating teams. Atropine was available at all centers, but more specific antidotes such as hydroxycobolamine, thiosulphate, or pralidoxime were less available (47, 47, and 19%, respectively). Six percent of hospitals had radiodetection equipment with an alarm function and 14% had a nuclear specialist available 24/7. Infectiologists were continuously available in 26% of the total EDs surveyed. Individual isolation facilities were present in 36% of the EDs, and isolation facilities capable of housing larger groups were present in 9%. University hospitals were significantly better prepared than community hospitals. CONCLUSION: There are serious gaps in hospital preparedness for CBRN incidents in Belgium. Lack of financial resources is a major obstacle in achieving sufficient preparedness. Language: en

OBJECTIVES: A mass carbon monoxide (CO) intoxication during an ice-hockey game is described. Two hundred and thirty-five patients were seen in different hospitals, 88 of them the same night at the nearby emergency department. To evaluate long-term implications and to identify relevant indicators, a follow-up study was organized 1 year after the incident. METHODS: Apart from the file data from the emergency departments, a 1-year follow-up mailing was sent to all patients. RESULTS: One hundred and ninety-one patients returned their questionnaire (86%). The mean age of the patients was 28 years, with 61% men. The mean carboxyhaemoglobin (COHb) was 9.9%. COHb levels were significantly higher for individuals on the ice (referee, players and maintenance personnel). There was a significant relationship with the initial presence of dizziness, fatigue and the COHb level. Headache, abdominal pain, nausea and vomiting were not significantly related to the COHb levels. The relationship between symptoms and CO level, however, should be interpreted with caution as there was a wide range between exposure and blood tests. 5.2% of patients had residual complaints, all including headache, with a significant higher incidence with high COHb levels. Only two patients had an abnormal neurological control (one slightly disturbed electroencephalography and one persistent encephalopathic complaint). Work incapacity was also significantly related to COHb levels. CONCLUSION: CO mass poisonings remain a risk in indoor sporting events. Although it causes an acute mass casualty incident, it is limited in time and delayed problems are scarce. Symptomatology is a poor tool for triage. The best prevention is the use of nonmineral energy sources such as for example electricity. Language: en

The differential diagnosis between viral meningitis and bacterial meningitis is often very difficult. The results of peripheral blood and spinal fluid analysis are not 100% accurate. We tried to find a useful 'bedside' decision-making tool, based on laboratory results readily available at the emergency department.Retrospective study design. Analysis of a consecutive series of all children (age 0-15 years) admitted to the paediatric ward because of a viral or bacterial meningitis, in the period from 1997 to September 2005.Seventy-one children with viral and 21 with bacterial meningitis were included. Bacterial meningitis occurred at much younger ages than viral meningitis. The paediatrician decided to administer antibiotics in 41 of 71 children with viral meningitis and in all children with bacterial meningitis. We developed a 'bacterial meningitis score' based on C-reactive protein in peripheral blood, as well as glucose and protein in cerebrospinal fluid. Using this score, we could distinguish 54 of 71 patients with viral meningitis from the group with bacterial meningitis. When the dispensing of antibiotics was based on this score, only 16 patients with viral meningitis would receive antibiotics.We present a bedside bacterial meningitis score. Using this bacterial meningitis score as a decision-making tool, we would be able to avoid antibiotics in a large number of children with viral meningitis. As this gives a 100% success rate, thus guaranteeing that bacterial meningitis patients would receive the proper therapy, our bacterial meningitis score could be an accurate decision-support tool.

Clearing the cervical spine after blunt trauma remains a challenge. Even in the computed tomography era many emergency departments worldwide still use classical X-rays in first evaluation. Low odontoid fractures are frequently missed, especially in unconscious patients where an open mouth view is not available. Evaluation of the Harris ring in the lateral view can improve identification rate. We studied the diagnostic values of this sign and the educational effect on trainees. Lateral views of 12 computed tomography confirmed low-axis fractures and 13 controls were randomly presented to 17 residents (traumatology, neurosurgery and emergency medicine) and five experienced radiologists. After the residents were taught the use of the axis ring, they had to review the set. Diagnosis was scored with a degree of certitude from 5 to 1. The specificity and sensitivity for the radiologists was 88% (confidence interval 80-96) and 82% (confidence interval 72-91), respectively. The effect of the education on the scores of the residents was evaluated using the Wilcoxon ranking test with a significant effect for the traumatologists (P=0.0008), emergency physicians (P=0.0005) as well for the neurosurgeons (P=0.0087). The axis ring can be a useful diagnostic tool in identifying low odontoid fractures on cross-table cervical spine X-rays. It is easy to teach and should be included in X-ray-based C-spine clearing protocols.

Virulent airborne diseases can be a real burden to a nation's health system. The most recent threat is the fear of a mutation-induced H5N1-influenza pandemic. We studied whether Belgian hospitals are able to deal with H5N1-influenza infected patients in the case of a pandemic. Many patients, including children, may require artificial ventilation within 48 h after admission.A survey aimed at determining 'availability and preparedness' was sent by e-mail to the different Belgian Emergency Departments.Sixty-five hospitals were finally included. The amount of patients being potentially admitted is limited, owing to the reduced number of intensive care beds equipped with automatic ventilators. Furthermore, the number of available intensive care beds for children is still lower than for adult patients. The number of mortuary places, in the case of a catastrophe, is also insufficient. Although most hospitals set up a disaster plan on H5N1, there are only limited stocks of antiviral medication to protect the hospital staff in the acute phase. A separate triage area is only available in a limited number of hospitals. We conclude that Belgian hospitals and emergency departments are not equipped to deal with potential pandemic situations.

Diaphragmatic rupture is an uncommon and frequently missed complication in blunt thoraco-abdominal trauma. Symptoms usually become apparent in a delayed phase, up to years after the trauma. An acute presentation is extremely rare and acute tension gastrothorax in which trapping of air in the intrathoracic stomach causes mediastinal shift and lung compression, as in tension pneumothorax, is exceptional. We only found two cases in the literature. We present here two other cases from our practice, with a review on the literature on post-traumatic diaphragmatic hernias.

Although exercise-induced hematuria is a well known finding in long distance running, it is extremely rare in cycling. We describe a case of gross atraumatic hematuria after mountainbiking. The only pathologic finding in our patient was a small hyperemic zone in the bladder mucosa suggesting a local traumatic origin due to repeated contact of the flaccid bladder wall against the bladder base. This in contrast with the renal origin commonly seen in marathon runners. It is a benign hematuria that usually resolves within a day without specific treatment. The best treatment is prevention by means of good bladder filling. Neoplasm of the urothelium should be ruled out in differential diagnosis.

Ecstasy is a very popular and widely used party drug with known complications such as agitation, hyperpyrexia, rhabdomyolysis or renal failure. A 16-year-old boy was admitted to our Emergency Department with a spontaneous pneumomediastinum (SPM) after Ecstasy ingestion, complicated by myocarditis. To our knowledge this is the first case described with the combination of Ecstasy ingestion, SPM and myocarditis. Although SPM is well known in inhalation drug users who try to enhance alveolar resorption with repeated valsalva manoeuvres, it is rather rare after the ingestion of party drugs. The probable causative event is the prolonged and excessive dancing in this party drug culture. The course is usually benign, with spontaneous resorption. Emergency physicians should be aware of the risk, especially if a drug user presents with neck emphysema, difficulty in swallowing, and precordial crepitations or thoracic pain. Ecstasy, similarly to cocaine, can induce cardiac symptoms.
