Alcohol-related emergency department admissions among adolescents in the Ghent and Sint-Niklaas areas.

Alcohol abuse is a major health concern. The aim of this retrospective study was to analyse the alcohol-related emergency department (ED) admissions among adolescents in all hospitals of distinct areas during a 1-year period. In each hospital, all ED patients with a blood alcohol concentration (BAC) of at least 0.5 g/l were surveyed in a standardised way. Of the 3918 included patients, only 146 (3.7%) were < 18  years. The male-to-female ratio was 1.5:1. There was a strong preponderance of weekend and night time admissions. Most of the patients were transported by ambulance (77% of 138 patients with information on this item). The main reason for ED admittance was depressed level of consciousness (64%), trauma (12%), vomiting and/or abdominal pain (12%), agitation or aggression (4%), syncope (4%) and psychological problems (4%). The context of the alcohol intoxication was related to some kind of festivity in 85%, mental problems in 14% and chronic abuse in 1%. Median BAC values (and range) were 2.08 g/l (0.73-3.70 g/l) for boys and 1.51 g/l (0.73-2.90 g/l) for girls. Most patients (87%) could be discharged home within 24  hours. Our study confirms that problematic alcohol use leading to ED admissions starts in adolescence. Although the numbers of cases below 18 years are low when compared to adults, the phenomenon is alarming as it is associated with substantial health problems. Therefore, Belgium urgently needs a global national alcohol plan, with youngsters being one of the target groups.

Metformin-associated lactic acidosis (MALA): case report.

Metformin is the first-line therapy for the treatment of diabetes mellitus. In certain conditions lactic acidosis (MALA) can occur. Starting with a case report of a 62-year-old woman presenting with abdominal pain, we bring this complication to attention, describing its pathogenesis and its management. This underlines the need for thoughtful use of metformin.

Diagnostic yield of syncope investigation (initiated) in the emergency department: a pilot study.

OBJECTIVE: To determine the diagnostic yield of investigations in patients presenting to the emergency department (ED) with syncope. To determine the cause of the syncope. PATIENTS AND METHODS: We retrospectively identified consecutive patients presenting to the ED who underwent investigations for syncope at a 1900 bed university teaching hospital during 4 months. From the medical records we abstracted clinical information, results of testing and the cause of syncope. RESULTS: A total of 117 patients participated in the study. The mean age was 57 year (range 6-93 year), and 45% were male. Diagnostic procedures most often performed were blood analysis, ECG, chest X-ray and Holter monitoring (respectively in 94.1%, 88.8%, 74.4% and 36,8% of the patients). The corresponding diagnostic yield for these test was 4.5%, 6.7%, 0% and 16.3%. Other procedures were (% of patients; diagnostic yield): Ct scan of the head (35.1%; 0%), transthoracic echocardiogram (24.8%; 6.9%), ECG monitoring (24.8%; 27.6%), EEG (19.7%; 0%), neurovascular imaging (19.7%; 0%), abdominal ultrasound (11.1%; 0%), Ct scan of the chest (11.1%; 23.1%), head up tilt test (7.7%; 11.1%), carotid sinus massage (3.4%; 0%), pulmonary ventilation perfusion scintigraphy (2.6%; 33%) and exercise test (1.7%; 0%). The most common cause of syncope was neurocardiogenic (58,5% of patients), followed by orthostatic (11.1%), cardiac (11.1%), unknown (9.3%), hyperventilation (3.4%), pulmonary embolism (2.5%), drug related (2.5%) and others (1.7%). CONCLUSION: Patients admitted in the ED for syncope undergo various investigations. However, the diagnostic yield is poor.The most common cause of syncope is neurocardiogenic, followed by orthostatic and cardiac.

Severity (and treatment) of chronic lithium poisoning: clinical signs or lab results as a criterion?

A 60-year-old woman with a lithium intoxication presented initially to the emergency department with a Glasgow coma scale (GCS) of 15/15. With initial conservative treatment (hydratation) she developed coma, necessitating haemodialysis. During haemodialysis there was no clinical improvement although there was a drop in the serum lithium levels. However, neurological recovery occurred after the first haemodialysis session, while the Lithium level rose again. This case illustrates initial clinical deterioration despite decreasing lithium levels as well as consequent clinical improvement without drop in lithium levels. This case also illustrates the pharmacokinetic profile of lithium and supports the use of primarily clinical signs completed with serum levels of lithium to determine the severity of a lithium poisoning and the adequate therapy including dialysis.

Finding exact spatial soliton profiles in nematic liquid crystals.

Finding exact analytical soliton profile solutions is only possible for certain types of non-linear media. In most cases one must resort to numerical techniques to find the soliton profile. In this work we present numerical calculations of spatial soliton profiles in nematic liquid crystals. The nonlinearity is governed by the optical-field-induced liquid crystal director reorientation, which is described by a system of coupled nonlinear partial differential equations. The soliton profile is found using an iterative scheme whereby the induced waveguide and mode profiles are calculated alternatively until convergence is achieved. In this way it is also possible to find higher order solitons. The results in this work can be used to accurately design all-optical interconnections with soliton beams.

Short-term return visits of 'general internal medicine' patients to the emergency department: extent and risk factors.

OBJECTIVES: Although emergency department (ED) return visits are a significant problem universally, it has not been previously studied in our ED. The aim of this study was to determine the extent of the problem in our ED, to identify the relevant clinical predictor variables and to detect diagnostic errors. METHODS: A retrospective observational study of ED return visits by patients managed by the General Internal Medicine (GIM) service was performed. The study was performed over a one year period at a tertiary hospital ED. Data are reported as relative risk (RR) and 95% confidence interval (CI). RESULTS: There were a total of 51.210 ED visits during the study period. The total number of ED return visits within 72 hours was 1.124 (2,19%; 95% CI 2,07 to 2,32). The total number of ED patients managed by the GIM service was 9.511. The percentage of patients treated by the GIM service who returned to the ED within 72 hours was 1,48% (95% CI 1,25 to 1,74) when calculated for the whole group and 2,9 % (95% CI 2,46-3,41) for those discharged home from the ED (n = 4.860). The majority (82,98%) of ED return visits by patients discharged from the GIM service were unscheduled and related to their index presenting complaint. Abdominal pain was the commonest initial presenting symptom in the patients who returned to the ED after discharge. Patients with diarrhoea as the initial initial presenting symptom had the highest relative risk of an ED return visit (RR = 4.07). CONCLUSION: The percentage ED return visits by patients discharged from the ED by the GIM service is 1,48%. Patients presenting with diarrhoea as the initial presenting symptom have the highest relative risk of an early ED return visit. Our main practical conclusion is that patients with abdominal pain need to be re-examined carefully and instructed about potential evolution before discharge.

18-fluoro-deoxyglucose positron emission tomography may contribute to the diagnosis and follow-up of malakoplakia.

Malakoplakia is a rare inflammatory disease involving most frequently the urinary tract. We present a case of bilateral renal malakoplakia, in which FDG-PET contributed to diagnosis. We made this diagnosis on the basis of clinical presentation, renal biopsy showing a mixed cellular infiltrate with granuloma formation and possible Michaelis-Gutmann bodies, resolution of the lesions after prolonged antibiotic therapy and evidence of leukocyte dysfunction. We briefly discuss the pathophysiology and therapy of this rare and difficult to prove disease and the role of FDG-PET in the diagnosis of inflammatory and infectious diseases.
