SARS had caused a significant level of distress among ED staff. The distress level was highest for nurses, followed by doctors and HCA. The three most important variables that could account for the distress level were loss of control/vulnerability, fear for self-health and spread of the virus. Overall, the more frequently adopted coping strategies were acceptance, active coping, and positive framing.

OBJECTIVE To report the clinical spectrum seen in young abusers of street‐ketamine (regular recreational abusers of street‐ketamine, for its hallucinogenic effects) in Hong Kong, presenting with significant lower urinary tract symptoms (LUTS) but with no evidence of bacterial infection. PATIENTS AND METHODS We retrospectively analysed the clinical presentations, pelvic pain and urgency/frequency scores, video‐urodynamic studies, cystoscopy findings, histological features of bladder biopsies and radiological findings of 59 ketamine abusers who were referred to the urology units of Princess Margaret and Tuen Mun Hospital, Hong Kong, from March 2000 to December 2007. RESULTS Of the 59 patients, all had moderate to severe LUTS, i.e. frequency, urgency, dysuria, urge incontinence and occasionally painful haematuria. Forty‐two (71%) patients had a cystoscopy that showed various degrees of epithelial inflammation similar to that seen in chronic interstitial cystitis. All of 12 available bladder biopsies had histological features resembling those of interstitial cystitis. Urodynamically, either detrusor overactivity or decreased bladder compliance with or without vesico‐ureteric reflux was detected to some degree in all of 47 patients. Thirty patients (51%) had unilateral or bilateral hydronephrosis on renal ultrasonography, and four (7%) showed features suggestive of papillary necrosis on radiological imaging. Eight patients had a raised serum creatinine level. CONCLUSION A syndrome of cystitis and contracted bladder can be associated with street‐ketamine abuse. Secondary renal damage can occur in severe cases which might be irreversible, rendering patients dependent on dialysis. The present data do not establish the precise cause nor the incidence. Street‐ketamine abuse is not only a drug problem, but might be associated with a serious urological condition causing a significant burden to healthcare resources.

Objective:To update our epidemiological knowledge of acute poisoning in Hong Kong. Methods: A multicentred prospective study was conducted for six months in six major accident and emergency departments in Hong Kong. A specially designed form was used to collect demographic data, type of poison involved, cause of poisoning, management, disposal as well as final outcome of the poisoned patients. Results: A total of 1,467 patients (male: 588, female: 879) were included in the study. Most of them were young adults (32% were between 20 and 40 years old). Suicidal attempt (64%) was the most common cause of poisoning. Notably, 379 (26%) patients took more than one poison. Among the 2,007 counts of poison taken, sleeping pills (24%) and analgesics (18%) were the most commonly used drugs and paracetamol was the commonest single ingredient involved in poisoning. Most patients were treated with supportive measures, and about 40% and 15% of the patients were given gastrointestinal decontamination and specific antidotes respectively in their management, in which activated charcoal and N-acetylcysteine were the most common. Concerning disposal from the emergency department, 91% of the poisoned cases required in-patient management. Most patients had an uneventful recovery but 5 (0.3%) had significant disability and 21 (1.4%) died. Suicidal carbon monoxide poisoning was the leading cause of mortality in our study. Conclusions: Most acute poisonings in Hong Kong were suicidal in nature and paracetamol was the commonest agent. Activated charcoal was the most commonly used decontamination method and most patients had an uneventful recovery. (Hong Kong j.emerg.med. 2005;12:156-161)

Emergency neurosurgical consultation assisted by TR and VC achieved a higher diagnostic accuracy in comparison with conventional TC. Although VC did not show an advantage over TR in process-of-care indicators, clinical outcome, and cost, it has been proven to be a safe mode of consultation in emergency neurosurgery.
