RESUMO
BACKGROUND: Digoxin poisonings are relatively common and potentially fatal, requiring immediate therapeutic intervention, with special attention to the patient's hemodynamic status and the presence of electrocardiographic and electrolytic disturbances. OBJECTIVE: To identify factors associated with seven-day and thirty-day mortality in digoxin poisoning. DESIGN, SETTINGS AND PARTICIPANTS: A retrospective, observational, multicenter study was conducted across 15 Hospital Emergency Departments (HED) in Spain. All patients over 18 years of age who presented to participating HEDs from 2015 to 2021 were included. The inclusion criteria encompassed individuals meeting the criteria for digoxin poisoning, whether acute or chronic. OUTCOMES MEASURE AND ANALYSIS: To identify independent factors associated with 7-day and 30-day mortality, a multivariate analysis was conducted. This analysis included variables of clinical significance, as well as those exhibiting a trend (p < 0.1) or significance in the bivariate analysis. MAIN FINDINGS: A total of 658 cases of digoxin poisoning were identified. Mortality rates were 4.5% (30 patients) at seven days and 11.1% (73 patients) at thirty days. Regarding 7-day mortality, the mean age of deceased patients was comparable to survivors (84.7 (8.9) vs 83.9 (7.9) years; p = ns). The multivariate analysis revealed that factors independently associated with 7-day mortality encompassed the extent of dependence assessed by the Barthel Index (BI 60-89 OR 0.28; 95% CI 0.10-0.77; p = 0.014 and BI>90 OR 0.22; 95% CI 0.08-0.63; p = 0.005), the identification of ventricular arrhythmias (OR 1.34; 95% CI 1.34-25.21; p = 0.019), and the presence of circulatory (OR 2.84; 95% CI 1.19-6.27; p = 0.019) and neurological manifestations (OR 2.67; 95% CI 1.13-6.27; p = 0.025). Factors independently associated with 30-day mortality encompassed extent of dependence (BI 60-89 OR 0.37; 95% CI 0.20-0.71; p = 0.003 and BI>90 OR 0.18; 95% CI 0.09-0.39; p < 0.001) and the identification of circulatory (OR 2.13; 95% CI 1.10-4.15; p = 0.025) and neurological manifestations (OR 2.39; 95% CI 1.25-3.89; p = 0.006). CONCLUSIONS: The study identifies the degree of dependency assessed by the Barthel Index and the presence of cardiovascular and neurological symptoms as independent predictors of both 7-day and 30-day mortality. Additionally, the detection of ventricular arrhythmia is also an independent factor for 7-day mortality.

BACKGORUND & AIMS: Mushroom poisoning with Amanita phalloides or similar species can lead to liver failure with 10-30% mortality rates. We aimed at defining the prognostic value of urinary amatoxin quantification in patients with hepatotoxic mushroom poisoning. METHODS: Data from 32 patients with hepatotoxic mushroom poisoning (Hospital Clínic Barcelona, 2002-16) in whom urinary amatoxins were determined (ELISA) were retrospectively reviewed. Correlations between urinary amatoxin and collected baseline variables with outcomes including hepatotoxicity (ALT>1000 U/L), severe acute liver injury (ALI, prothrombin <50%), acute liver failure (ALF, ALI and encephalopathy), transplantation/death and hospital length-of-stay, were evaluated. RESULTS: 12/32 patients developed increased aminotransferase activity. Among the 13/32 amatoxin negative patients, 1 developed ALI and 12/13 no hepatotoxicity. Among the 19/32 amatoxin positive patients, 8/19 (42%) developed hepatotoxicity, including 5 who progressed to severe ALI, of whom 3 developed ALF (2 deaths, 1 transplantation). Urinary amatoxin and prothrombin were independent predictors of hepatotoxicity, ALT peak values (along with age) and hospital length-of-stay. In positive amatoxins patients, urinary concentrations > 55 ng/ml (or a baseline prothrombin ≤ 83%), were associated to hepatotoxicity (presented by 8/9 patients with ALT>1000 U/L). Among 5 patients with urinary amatoxin ≥ 70 ng/ml, 4 developed severe ALI. CONCLUSIONS: In patients with hepatotoxic mushroom poisoning, a negative urinary amatoxin quantification within 72h of intake ruled out the risk of hepatotoxicity in 92% of patients, whereas positive urinary amatoxins were associated with hepatotoxicity and severe ALI. Concentrations >55 ng/ml and ≥ 70 ng/ml were predictive of hepatotoxicity and severe ALI, respectively.

Jellyfish stings often cause immediate local skin reactions, and, less frequently, the affected individuals may develop delayed allergic reactions days or months after the sting. Here, we present 4 such cases. In all cases, color Doppler ultrasonography was performed at the time of diagnosis, and in 3 of the cases, clinical follow-ups with ultrasonographic evaluations were performed. Ultrasonography initially showed dermal thickening with decreased echogenicity that progressively normalized during follow-up. Ultrasonography was useful in quantifying inflammation by measuring the thickness of the dermis and was more precise than standard clinical follow-up of cutaneous lesions in these cases.

Heavy cannabis use is associated with reduced motivation. The basal ganglia, central in the motivation system, have the brain's highest cannabinoid receptor density. The frontal lobe is functionally coupled to the basal ganglia via segregated frontal-subcortical circuits conveying information from internal, self-generated activity. The basal ganglia, however, receive additional influence from the sensory system to further modulate purposeful behaviors according to the context. We postulated that cannabis use would impact functional connectivity between the basal ganglia and both internal (frontal cortex) and external (sensory cortices) sources of influence. Resting-state functional connectivity was measured in 28 chronic cannabis users and 29 controls. Selected behavioral tests included reaction time, verbal fluency and exposition to affective pictures. Assessments were repeated after one month of abstinence. Cannabis exposure was associated with (1) attenuation of the positive correlation between the striatum and areas pertaining to the 'limbic' frontal-basal ganglia circuit, and (2) attenuation of the negative correlation between the striatum and the fusiform gyrus, which is critical in recognizing significant visual features. Connectivity alterations were associated with lower arousal in response to affective pictures. Functional connectivity changes had a tendency to normalize after abstinence. The results overall indicate that frontal and sensory inputs to the basal ganglia are attenuated after chronic exposure to cannabis. This effect is consistent with the common behavioral consequences of chronic cannabis use concerning diminished responsiveness to both internal and external motivation signals. Such an impairment of the fine-tuning in the motivation system notably reverts after abstinence.

OBJECTIVE: According to a previous study, 17% of patients who attended an emergency department (ED) following cocaine use returned to the same ED over the next year for a problem related to drug use. This previous study proposed a scale (Multicenter Assessment of the Revisit Risk In the Emergency Department (MARRIED)-cocaine score) to quantify the risk of ED revisit. The aim of the present study was to validate this scale by analysing a new set of patients attending for cocaine use in nine Spanish EDs. METHODS: We performed a retrospective, multicentre, cohort study with consecutive patient inclusion, and without an intervention or control group. During 12â months (January-December 2010) we collected data from patients attending the ED after cocaine use. The MARRIED-cocaine score, ranging from 0 to 400 points, was calculated for each patient. The dependent variable was the identification of further visits associated with drug consumption to the same ED. Further analysis was performed to define risk categories. RESULTS: The study included 933 patients, with a mean follow-up of 466 (SD 189) days, and 185 patients returned to the same ED for problems related to drug consumption. The cumulative probability of ED revisit was 4.2%, 8.3%, 16.8% and 21.2% at 1 month, 3 months, 12 months and 24â months, respectively. The area under the curve receiver operating characteristic for the MARRIED-cocaine scale was 0.69 (p<0.001). Four categories for ED revisit risk were defined: low risk (0-40 points, n=416), moderate risk (41-100 points, n=235), high risk (101-210 points, n=71) and very high risk (210-400 points, n=211), with HRs for ED revisit (with respect to the low-risk group) of 1.82 (95% CI 1.18 to 2.80, p=0.007), 2.65 (95% CI 1.50 to 4.66, p=0.001) and 5.06 (95% CI 3.49 to 7.35, p<0.001), respectively. CONCLUSIONS: The MARRIED-cocaine score has a moderate discriminative capacity to predict revisit among patients who attend the ED for cocaine drug-related emergencies, and allows classification of patients according to the risk of ED revisit.

Neuroimaging studies have shown that chronic consumption of cannabis may result in alterations in brain morphology. Recent work focusing on the relationship between brain structure and the catechol-O-methyltransferase (COMT) gene polymorphism suggests that functional COMT variants may affect brain volume in healthy individuals and in schizophrenia patients. We measured the influence of COMT genotype on the volume of four key regions: the prefrontal cortex, neostriatum (caudate-putamen), anterior cingulate cortex and hippocampus-amygdala complex, in chronic early-onset cannabis users and healthy control subjects. We selected 29 chronic cannabis users who began using cannabis before 16 years of age and matched them to 28 healthy volunteers in terms of age, educational level and IQ. Participants were male, Caucasians aged between 18 and 30 years. All were assessed by a structured psychiatric interview (PRISM) to exclude any lifetime Axis-I disorder according to Diagnostic and Statistical Manual for Mental Disorders-Fourth Edition. COMT genotyping was performed and structural magnetic resonance imaging data was analyzed by voxel-based morphometry. The results showed that the COMT polymorphism influenced the volume of the bilateral ventral caudate nucleus in both groups, but in an opposite direction: more copies of val allele led to lesser volume in chronic cannabis users and more volume in controls. The opposite pattern was found in left amygdala. There were no effects of COMT genotype on volumes of the whole brain or the other selected regions. Our findings support recent reports of neuroanatomical changes associated with cannabis use and, for the first time, reveal that these changes may be influenced by the COMT genotype.

Multiple chemical sensitivity (MCS) is characterized by a loss of tolerance to a variety of environmental chemicals. Multiple chemical sensitivity is frequently triggered by exposure to chemical agents, especially insecticides. The aim of the study was to measure the sense of smell and quality of life in patients with MCS compared to the control group. We studied the sense of smell, both sensitive and sensorial characteristics, in female patients with MCS (n = 58, mean 50.5 ± 8.5 years) and healthy female volunteers without rhinosinusal pathologies (n = 60, mean age 46 ± 10.2 years). Olfactometry (Barcelona Smell Test 24/BAST-24), sinonasal symptoms (visual analogue scale/VAS 0-100 mm), and quality of life (Quick Environmental Exposure and Sensitivity Inventory/QEESI) were assessed. Multiple chemical sensitivity patients showed a significant impairment in smell identification (19 ± 12 %; p > 0.05) and forced choice (62 ± 18 %; p > 0.05), but not in smell detection (96 ± 4 %) compared to the control group. Multiple chemical sensitivity patients reported more odours as being intense and irritating and less fresh and pleasant when compared with the control group. Patients scored a high level (40-100) on QEESI questionnaire (symptom severity, chemical intolerances, other intolerances, life impact). In MCS patients, total symptom intensity (VAS/0-700 mm) score was 202 ± 135, while disease severity score was 80 ± 23. The most frequent symptoms were itching and posterior rhinorrhea. Multiple chemical sensitivity patients have an impairment in smell cognitive abilities (odour identification and forced choice, but not for detection) with increased smell hypersensitivity and poor quality of life.

OBJECTIVES: Digoxin toxicity accounts for a small percentage of poisonings attended by emergency departments. This study aimed to describe differences between acute and chronic digoxin toxicity and assess the use of digoxin-specific antibody fragments (digoxin-Fab) as an antidote. MATERIAL AND METHODS: Retrospective, observational, multicenter study in 15 hospital emergency departments in 8 Spanish autonomous communities in 7 years. We collected patient, clinical and treatment variables, and discharge destination. Patients were classified according to whether toxicity was acute or chronic and whether digoxin-Fab was administered or not. RESULTS: Twenty-seven acute and 631 chronic digoxin poisonings were attended. The mean (SD) patient age was 83.9 (7.9) years, and 76.9% were women. Patients with acute toxicity were younger (80.0 [12] years) than those with chronic toxicity (84.1 [7.7] years) (P .038), and accidental poisoning was less common (in 85.2% vs 100% in chronic toxicity; P .001). Cases of acute toxicity were also more serious (Poison Severity Score (29.6% vs 12.5% in chronic toxicity; P .001). Thirty-four patients were treated with digoxin-Fab (5.4%). These patients were younger (78.7 [11.5] years vs 84.2 (7.6) years), their toxicity was more often acute (in 20.6% vs 3.2% in chronic toxicity), more had attempted suicide (8.8% vs 0.2% with chronic toxicity), and more had severe symptoms (50% vs 11.2%) (P .001, all comparisons). Hospital admission was required for 76.1%. Overall, mortality was 11.4%. CONCLUSION: Chronic toxicity accounts for most digoxin poisoning cases, and most patients are women. Acute toxicity is more serious. Patients who required digoxin-Fab have more severe poisoning. Such patients usually have acute toxicity, and attempted suicide is more often the reason for the emergency.
OBJETIVO: Las intoxicaciones por digoxina representan un pequeño porcentaje de las intoxicaciones atendidas en urgencias. El objetivo de este estudio fue describir las diferencias entre intoxicaciones agudas y crónicas y evaluar la administración de su antídoto específico: los anticuerpos antidigoxina (AcAD). METODO: Estudio retrospectivo, observacional y multicéntrico en 15 servicios de urgencias hospitalarios de 8 comunidades autónomas durante 7 años. Se recogieron datos de filiación, clínica, tratamiento y destino al alta. Los pacientes se dividieron según era la intoxicación aguda o crónica y según recibían o no AcAD. RESULTADOS: Se recogieron 27 intoxicaciones agudas y 631 crónicas. La edad media fue de 83,9 (7,9) años, y el 76,9% eran mujeres. Los pacientes con intoxicación aguda tenían menor edad media (80,0 (12) vs 84,1 (7,7) años; p 0,038), y porcentaje de causa accidental (85,2% vs 100%; p 0,001) y mayor gravedad en la escala Poison Severity Score (29,6% vs 12,5%; p 0,001). Treinta y cuatro pacientes recibieron AcAD (5,4%) y constituyen un grupo de menor edad [78,7 (11,5) vs 84,2 (7,6); p 0,001], con mayor porcentaje de intoxicaciones agudas (20,6% vs 3,2%), intencionalidad suicida (8,8% vs 0,2%) y gravedad (50% vs 11,2%, p 0,001 en todas las comparaciones). El 76,1% precisó ingreso. La mortalidad fue del 11,4%. CONCLUSIONES: Las intoxicaciones por digoxina suelen ser crónicas y predominan en mujeres. Las intoxicaciones agudas son de mayor gravedad. Los pacientes que precisaron administración de AcAD tenían intoxicaciones más graves y mayor porcentaje de intoxicaciones agudas y con intencionalidad suicida.

BACKGROUND: To describe the epidemiological profile and clinical manifestations of liquid ecstasy (GHB) poisonings. METHODS: All cases of GHB poisoning or overdose admitted to the Emergency Department (ED) of the Hospital Clinic (Barcelona) between 2000 and 2007 were recorded. RESULTS: A total of 505 patients (mean age 24.7 years, 68% men) were included. Most patients were brought to the hospital by ambulance (98%), during the weekend (89%) and during the early morning (75%). Symptoms began in a public place in 97%. Reduced consciousness was the most important clinical manifestation: 72% of patients had a Glasgow Coma Score of ≤ 12. 76% of patients had consumed other drugs: ethanol (64%), amphetamines and derivates (30%), cocaine (28%), ketamine (11%), cannabis (9%) and others (5%). Treatment was required in 26% of cases and an antidote was administered in 35 cases with no response. There were no deaths. The combined GHB group had a longer time to complete recovery of consciousness (71 ± 40 vs 59 ± 40 min, p < 0.001) and a higher percentage of patients with severely reduced consciousness at ED arrival (54% vs 37%, p = 0.01), need for treatment (29% vs 16%, p < 0.01) and need for mechanical ventilation (3% vs 0%, p < 0.05) compared with the pure GHB group. CONCLUSIONS: GHB intoxication leading to reduced consciousness is a frequent reason for ED admission, above all in young people and in the early morning at the weekend. Symptoms are more severe in patients who have taken GHB in combination with other substances of abuse.

OBJECTIVES: The Toxicology Working Group of the Catalan Society of Emergency Medicine (SoCMUETox) began the Intox-28 study in 2013. The aim was to identify differences in poisoning cases between 3 age groups. MATERIAL AND METHODS: Descriptive observational study of poisoning cases managed in 8 hospital emergency departments on the 28th day of each month from 2013 to 2019. We gathered information on patient particulars, type of poison, clinical data, and discharge destination. The patient sample was distributed into 3 groups for comparison: minors under the age of 17 years, adults aged 17 to 65 years, and adults over the age of 65 years. RESULTS: The hospitals registered 1088 cases: 132, 859, and 97 in each age group. In comparisons between the minors and the adults aged 65 years or younger, the minors had more females (58.3% vs 46.1%), fewer recreational poisonings (22% vs 46.1%) more poisonings inside the home (67.4% vs 51.1%), more medication poisonings (49.2% vs 31.1%), and less often received treatment (43.2% vs 73%) (P .001, all comparisons). The proportion of older adults receiving treatment (73.2%) was similar to that of the younger adults. CONCLUSION: The characteristics of poisonings vary according to age. Differences lie in gender, intentionality, and type of poison.
OBJETIVO: El Grupo de Trabajo de Toxicología de la Societat Catalana de Medicina d'Urgències i Emergències (SoCMUETox) inició en 2013 el estudio Intox-28. El objetivo de este trabajo es evaluar las diferencias existentes en las características de las intoxicaciones según la edad de los pacientes. METODO: Estudio descriptivo observacional de las intoxicaciones atendidas en 8 servicios de urgencias hospitalarios (SUH) el día 28 de cada mes durante el periodo 2013-19. Se recogieron datos demográficos, tipo de tóxico, datos clínicos y destino al alta. Los pacientes se dividieron en 3 grupos: menores de 17 años, adultos (entre 17 y 65 años) y mayores de 65 años. RESULTADOS: Se registraron 1.088 intoxicaciones: 132 (12,1%), 859 (78,9%) y 97 (8,9%) en cada grupo de edad respectivamente. En comparación a los pacientes adultos, en los menores de 17 años hubo más mujeres (58,3% vs 46,1%; p 0,001), menos intoxicaciones de tipo recreativo (22% vs 46,1%; p 0,001) y acontecieron más frecuentemente en el domicilio (67,4% vs 51,1%; p 0,001). El tipo de tóxico más implicado fueron los fármacos (49,2% vs 31,1%; p 0,001) y precisaron tratamiento con menor frecuencia (43,2% vs 73%; p 0,001). Los mayores de 65 años precisaron tratamiento en porcentaje similar a los pacientes de 17 a 65 años (73,2%). CONCLUSIONES: Existen diferencias entre los grupos de edad, entre las que destacan el sexo predominante, la intencionalidad de la intoxicación y el tipo de tóxico implicado.

BACKGROUND AND OBJECTIVE: To identify the pattern of use of activated charcoal in the treatment of poisonings, and to evaluate the prevalence and severity of adverse reactions and define the risk factors associated with them. PATIENTS AND METHOD: Observational, prospective 7-year study. Patients receiving activated charcoal for gut decontamination were included. Epidemiological, toxicological, therapeutic and evolutionary variables were studied. The dependent variable was the appearance of secondary effects related to the use of charcoal. RESULTS: A total of 575 patients were included. The mean age was 37.8 (14.8) years and 65.7% were women. Activated charcoal was administered orally in 88% of the patients and by gastric tube after lavage in 12%, and 2.4% of patients received charcoal before hospital arrival. Adverse reactions occurred in 41 cases (7.1%) and included nausea or vomiting (36 patients), bronchoaspiration (6 patients) and pneumonia (2 patients). Spontaneous vomiting before administration of charcoal (p < 0.001), pre-hospital administration of charcoal (p < 0.05), repeated doses (p < 0.01) and the need for symptomatic measures to treat intoxicated patients (p < 0.05) were independent risk factors for adverse reactions, whereas age ≥ 40 years (p < 0.05) and intoxication with benzodiazepines (p < 0.01) were independently associated with a smaller risk of adverse reactions. The mean emergency department stay was 10.2 (18.6) hours, and was significantly longer (p < 0.05) in patients suffering adverse reactions. A total of 75.4% of patients were discharged to home, 20.5% required psychiatric admission and 3.9% were admitted due to the clinical consequences of the poisoning. The prevalence of non-psychiatric admission to general hospital or intensive care was greater in patients suffering adverse reactions. No patient died. CONCLUSIONS: Adverse reactions to charcoal are infrequent and rarely severe, but are associated with a greater emergency department stay and a trend to greater hospital admission. Predisposing factors are vomiting before administration of charcoal and administration of repeated doses. Age ≥ 40 years and ingestion of benzodiazepines are protective factors.

BACKGROUND AND OBJECTIVE: Liquid ecstasy (GHB) is a new cause of drug overdose in our country. To describe the epidemiological profile and clinical manifestations, we analyzed cases of poisoning by GHB attended by the Emergency Departments (ED) of 2 hospitals of the city of Barcelona. PATIENTS AND METHOD: During two years (2003-2004) all cases of poisoning or overdose due to GHB attended in the ED of the Hospital del Mar and the Hospital Clinic of Barcelona were collected. The diagnosis was clinical and/or by means of toxicological analysis. Epidemiological, clinical, laboratory and therapeutic variables as well as the evolution were collected. RESULTS: A total of 339 patients (mean age 23.5 years, 62% male) were identified. Most patients (89%) were admitted during the early morning and during weekends (89%). Symptoms began in a public place in 97%. Reduced consciousness was the most important clinical manifestation, since 72% of patients had a Glasgow Coma Score of 12 or less. Seventy per cent stated having consumed GHB with other drugs, mainly ethyl alcohol (53%) and cocaine (16%). Some form of treatment was required in 32% of cases and 20 cases were administered an antidote: naloxone (12 cases), flumazenil (8 cases) and physostigmine (6 cases). Five patients needed orotracheal intubation and ventilatory support. One patient needed advanced vital support. There were no deaths. CONCLUSIONS: GHB intoxication leading to reduced consciousness is a frequent motive for admission to the ED, mostly in young people and in the early morning during the weekend. GHB intoxication should be discarded in all cases of coma of unknown origin.

We present a map of 24 indicators to measure the quality of care given to patients with acute poisoning attended in the emergency department. These include structural indicators (availability of protocols, stocks of antidotes, analytical tests, gastric lavage tubes), process indicators (correct indication of gut decontamination techniques, indications for renal and extra-renal purification, use of antidotes, indication of toxicological analyses, ECG, delays in care, psychiatric referrals, judicial notifications), indicators of results (mortality, compliance with minimum basic data set of poisonings, continuing staff education) and administrative indicators (publications).
RESUMO
OBJECTIVES: To identify the drugs usually abused in cases of acute poisoning in human immunodeficiency virus (HIV) infected patients. MATERIAL AND METHODS: Retrospective study of episodes of acute street drug poisoning in HIV-infected patients in our emergency department over a period of 1 year. Chemsex was defined as the use of methamphetamines, -hydroxybutyrate (GHB), -butyrolactone (GBL), and/or mephedrone in order to prolong sexual activity. RESULTS: We included 101 patients, 93 (92%) of whom were men. The drug that caused the most cases of acute poisoning was cocaine, detected in 52 patients (51%). GHB and amphetamines were the next most frequently implicated street drugs. The prevalence of chemsex in this series was 87%. Mortality was 2%. Amphetamine poisoning was related to intensive care unit admission (odds ratio, 9,2 [95% CI, 1.6-52.2], P=.012). CONCLUSION: Cocaine use was the main cause of acute poisoning in this series. The prevalence of chemsex was high.
OBJETIVO: Identificar la principales drogas de abuso que producen intoxicación aguda en el paciente VIH. METODO: Estudio retrospectivo de 1 año evolución de los episodios de intoxicación por drogas de abuso en el paciente VIH en un servicio de urgencias. Se definió chemsex como el consumo de metanfetamina, GHB/GBL o mefedrona para mantener relaciones sexuales prolongadas. RESULTADOS: Se incluyeron 101 pacientes, 93 (92%) eran varones. La principal droga fue la cocaína en 52 (51%) pacientes, seguida del GHB y anfetaminas. La prevalencia de chemsex fue del 87%. La mortalidad de la serie fue del 2%. El consumo de anfetaminas predijo ingreso en cuidados intensivos: OR 9,2 (IC 95% 1,6-52,2); p = 0,012. CONCLUSIONES: La cocaína fue la principal causa de intoxicación aguda. El chemsex tuvieron una elevada prevalencia.

BACKGROUND AND OBJECTIVE: Multiple chemical sensitivity (MCS) is characterized by a loss of tolerance to various environmental chemicals. The objective of this study was to describe patients with MCS seen in our hospital. PATIENTS AND METHOD: Patients consecutively seen by the Toxicology and Chronic Fatigue Units who presented symptoms of MCS were included. The diagnosis was clinical. All patients completed the Quick Environmental Exposure and Sensitivity Inventory (QEESI) questionnaire. RESULTS: Fifty-two patients were included. The average age (standard deviation) was 47.2 (7.6) years, and 46 (88%) were females. The origin of the syndrome was related to occupational exposure to various chemical agents in 31 cases (59.6%), including occupational accidents in 14 patients (fumigation of the workplace with insecticides). In 20 patients (38.5%), the syndrome could not be associated with any toxic exposure and was considered a manifestation of chronic fatigue syndrome. The QEESI showed mean scores of 72.9 (18.6) on the chemical inhalant intolerance scale, 45.5 (20.6) on the other intolerances scale, 69.8 (20.6) on the symptom severity scale, 4.4 (1.8) on the masking index and 66.6 (21.7) on the life impact scale. All patients were followed up for a minimum of 12 months, and during this period they remained stable with no deaths. CONCLUSIONS: MCS normally affects middle-aged women. It is frequently triggered by exposure to chemical agents, especially insecticides. An association with chronic fatigue syndrome is common. The prognosis is good but the patients' quality of life is seriously affected.

BACKGROUND AND OBJECTIVE: The consumption of cocaine has increased in Spain in recent years, leading to a probable increase in overdoses. The associated use of other drugs of abuse may be increasing the toxicity of cocaine, and therefore, increasing consultations to the emergency department (ED). PATIENTS AND METHOD: We collected patients seen by the ED of our hospital who reported cocaine consumption in the previous hours. The relationship between cocaine consumption and the reason for attending the ED was analysed. We reviewed the medical records of a sample of overdoses to determine the clinical profile. RESULTS: During the period 2002-2004, 745 patients were detected (average age 31 years, 68% males). The annual distribution was 223 cases in 2002, 232 in 2003, and 290 in 2004. Fifty-three percent of patients attended the ED at the weekend and 53% from 0:00 to 12:00 h. The main drugs associated with cocaine consumption were ethyl alcohol (38%), opiates (14%), cannabis (13%) and amphetamine derivatives (9%). Cocaine was the substance causing clinical symptoms in 70% of cases. The main reasons for attending the ED were anxiety or agitation (48%) and thoracic pain or palpitations (25%). Eleven percent of cases required hospital admission (19 intensive care unit) and 3 patients died. CONCLUSIONS: The consumption of cocaine, almost always associated with other drugs of abuse, has generated an increase in patients attending the ED. Although mortality is low, cocaine consumption generates substantial morbidity and frequent hospital admissions.
