Abstract
BACKGROUND Delirium is thought to be common across various settings of care; however, still little research has been conducted in rehabilitation. AIM We investigated the prevalence of delirium, its features and motor subtypes in older patients admitted to rehabilitation facilities during the three editions of the "Delirium Day project". METHODS We conducted a cross-sectional study in which 1237 older patients (age ≥ 65 years old) admitted to 50 Italian rehabilitation wards during the three editions of the "Delirium Day project" (2015 to 2017) were included. Delirium was evaluated through the 4AT and its motor subtype with the Delirium Motor Subtype Scale. RESULTS Delirium was detected in 226 patients (18%), and the most recurrent motor subtype was mixed (37%), followed by hypoactive (26%), hyperactive (21%) and non-motor one (16%). In a multivariate Poisson regression model with robust variance, factors associated with delirium were: disability in basic (PR 1.48, 95%CI: 1.17-1.9, p value 0.001) and instrumental activities of daily living (PR 1.58, 95%CI: 1.08-2.32, p value 0.018), dementia (PR 2.10, 95%CI: 1.62-2.73, p value < 0.0001), typical antipsychotics (PR 1.47, 95%CI: 1.10-1.95, p value 0.008), antidepressants other than selective serotonin reuptake inhibitors (PR 1.3, 95%CI: 1.02-1.66, p value 0.035), and physical restraints (PR 2.37, 95%CI: 1.68-3.36, p value < 0.0001). CONCLUSION This multicenter study reports that 2 out 10 patients admitted to rehabilitations had delirium on the index day. Mixed delirium was the most prevalent subtype. Delirium was associated with unmodifiable (dementia, disability) and modifiable (physical restraints, medications) factors. Identification of these factors should prompt specific interventions aimed to prevent or mitigate delirium.

Abstract
Introduction Delirium and sarcopenia are common, although underdiagnosed, geriatric
syndromes. Several pathological mechanisms can link delirium and low skeletal muscle mass, but few studies have investigated their association. We aimed to investigate (1) the association between delirium and low skeletal muscle mass and (2) the possible role of calf circumference mass in finding cases with delirium. Methods The analyses were conducted employing the cross-sectional “Delirium Day” initiative, on patient 65 years and older admitted to acute hospital medical wards, emergency departments, rehabilitation wards, nursing homes and hospices in Italy in 2017. Delirium was diagnosed as a 4 + score at the 4-AT scale. Low skeletal muscle mass was operationally defined as calf circumference ≤ 34 cm in males and ≤ 33 cm in females. Logistic regression models were used to investigate the association between low skeletal muscle mass and delirium. The discriminative ability of calf circumference was evaluated using non-parametric ROC analyses. Results A sample of 1675 patients was analyzed. In total, 73.6% of participants had low skeletal muscle mass and 24.1% exhibited delirium. Low skeletal muscle mass and delirium showed an independent association (OR: 1.50; 95% CI 1.09–2.08). In the subsample of patients without a diagnosis of dementia, the inclusion of calf circumference in a model based on age and sex significantly improved its discriminative accuracy [area under the curve (AUC) 0.69 vs 0.57, p < 0.001]. Discussion and conclusion Low muscle mass is independently associated with delirium. In patients without a previous diagnosis of dementia, calf circumference may help to better identify those who develop delirium.

Abstract
In order to determine the required duration of whole-body exposure to extreme cold (-110 °C) in males and females for achieving the same cold-induced response, a mathematical model of skin cooling kinetics was developed. This modeling is derived from the implementation of a new experimental cryotherapy protocol to obtain continuous skin temperature maps over time. Each 3-min whole-body cryostimulation session was divided into six incremental sessions of 30 s carried out over six consecutive days. Seventeen young, healthy subjects (8 males aged 22.6 ±3.0 years and 9 females aged 23.7 ±4.7 years) agreed to participate in this study. The smallest sex-related difference in temperature was found in the trunk area (2.93 °C after 3 min) while the greatest temperature drop was found in the lower limbs (5.92 °C after 3 min). The largest temperature variation was observed between the trunk and the lower limbs, and peaked at 2.67 °C in males and 6.99 °C in females. For both sexes, skin cooling kinetics showed a strong transient exponential type decrease followed by linear regression behavior. It appeared that for achieving the same cold-induced response, the required duration of cryostimulation is longer for males. For example, a trunk skin cooling of -12 °C could be achieved in 125s for females vs 170s for males (+36% longer); for the lower limbs, the same skin cooling magnitude could be reached after 87s for females vs 140s for males (+62% longer).

Abstract
OBJECTIVE Whole-Body Cryotherapy (WBC) has seen a recent surge in popularity with patients with inflammatory conditions, athletes, and even people seeking to improve general health and quality of life. WBC treatment usually requires participation in a dozen of 3-min long sessions. But compliance is considered difficult due to possible cold-induced unpleasant sensations. Based on hedonic psychology assumptions, ratings of pleasure-displeasure experienced during a taks or activity may be important to understand individual differences in attendance. METHODS Two hundred fifty nine customers from two French cryocenters took the Feeling Scale immediately after their first WBC session. RESULTS End affect appeared to be negatively valenced (M = -1.85, SD = 1.38, 95 % confidence interval: -2.02 to -1.68). Additional statistical analyses revealed a moderating influence of past experience, in women only. Similarly, BMI was found to be negatively associated with displeasure in women, but not in men. CONCLUSION These findings are discussed and further research directions are suggested.

Abstract
BACKGROUND We aimed at evaluating the feasibility and effects of intense (i.e. -90°C) whole-body cryostimulation (WBC) on somnolence and psychological well-being in an older-adult patient diagnosed with restless legs syndrome (RLS). METHODS An interrupted time series approach was used in which the efficacy of cryostimulation was evaluated by measuring self-reported fatigue, wake time sleepiness, and well-being several times prior to, during, and after exposure to treatment (i.e. daily 3-min sessions of intense WBC). RESULTS No adverse event occurred. Reported levels of sleepiness decreased immediately following the beginning of the treatment phase. In the same time, self-reported well-being significantly increased. Effects sizes were of large magnitude. CONCLUSION In summary, the present study demonstrated that daily exposure to extremely cold air in an enclosed space for 2 weeks was feasible and effective in promoting physical and psychological states in an older patient with sleep disturbances.

The CFD method was used to investigate the detailed flow field around the cyclist/bicycle system for a constant speed of 11.1 m/s (40 km/h) without wind. In complement, a mathematical model was used to determine the temperature-dependent power output in the range [-10; 40 °C]. The numerical investigation gives valuable information about the turbulent flow field in the cyclist's wake which evolves accordingly the surrounding temperature. A major result of this study is that the areas of overpressure upstream of the cyclist and of underpressure downstream of him are less extensive for a temperature of 40 °C compared to -10 °C. The results suggest that the aerodynamic braking effect of the bicycle is minimized when the air temperature is high, as a lower air density results in a reduction in drag on the cyclist. This study showed that the power required to maintain a constant speed is reduced when the temperature is high, the reason being a lower aerodynamic resistance.

Abstract
The aerodynamic drag of three different time-trial cycling helmets was analyzed numerically for two different cyclist head positions. Computational Fluid Dynamics (CFD) methods were used to investigate the detailed airflow patterns around the cyclist for a constant velocity of 15 m/s without wind. The CFD simulations have focused on the aerodynamic drag effects in terms of wall shear stress maps and pressure coefficient distributions on the cyclist/helmet system. For a given head position, the helmet shape, by itself, obtained a weak effect on a cyclist's aerodynamic performance (<1.5%). However, by varying head position, a cyclist significantly influences aerodynamic performance; the maximum difference between both positions being about 6.4%. CFD results have also shown that both helmet shape and head position significantly influence drag forces, pressure and wall shear stress distributions on the whole cyclist's body due to the change in the near-wake behavior and in location of corresponding separation and attachment areas around the cyclist.

Abstract
BACKGROUND The purpose of this case report is to highlight for the first time the way Medical Infrared Thermography can be a helpful tool to assist the surgeon in the surgical treatment of Hidradenitis Suppurativa inflammatory disease. METHODS A 36-year-old man with a 7-year history of Hidradenitis Suppurativa presented inflammatory nodules in the left axilla area corresponding to Hurley stage II. Choice is made to surgically treat this patient using a wide excision protocol combined with a postoperative second intention healing. For the study purpose, an IR FLIR SC620 camera (FLIR Systems, Wilsonville, OR), having a high resolution pixel detector of 640×480 pixels for greater accuracy and higher resolution, has been used. RESULTS For the first time in the literature, this case report on HS disease supports the idea that real-time medical infrared thermography may be helpful in establishing the true extent of disease preoperatively in the surgical room and in a similar manner, that this technique allows the surgeon to ensure all diseased lesions are removed during surgery. CONCLUSIONS At least, medical infrared thermography seems to be a powerful tool to control the final wide surgical wound, in order to minimize recurrence risk of such a disease.

Abstract
This article establishes the basics of a theoretical model for the constitutive law that describes the skin temperature and thermolysis heat losses undergone by a subject during a session of whole-body cryotherapy (WBC). This study focuses on the few minutes during which the human body is subjected to a thermal shock. The relationship between skin temperature and thermolysis heat losses during this period is still unknown and have not yet been studied in the context of the whole human body. The analytical approach here is based on the hypothesis that the skin thermal shock during a WBC session can be thermally modelled by the sum of both radiative and free convective heat transfer functions. The validation of this scientific approach and the derivation of temporal evolution thermal laws, both on skin temperature and dissipated thermal power during the thermal shock open many avenues of large scale studies with the aim of proposing individualized cryotherapy protocols as well as protocols intended for target populations. Furthermore, this study shows quantitatively the substantial imbalance between human metabolism and thermolysis during WBC, the explanation of which remains an open question.

Abstract
Third-generation direct methods programs are based on a phasing algorithm (e.g.the tangent or the parameter shift method) and on dual space refinement techniques. The two spaces may be alternated during the phasing procedure or used in a sequential way: for example, first phase and after extend and refine. The tangent approach inSIR2011belongs to the second category: phases are first estimated by the tangent formula, then their extension and refinement is performed in direct spaceviaelectron density modification techniques. In this article a number of new algorithms are described, with the aim of improving theSIR2011tangent step and allowing more efficient phase extension and refinement. New criteria were chosen for defining the number of reflections to phase, for modifying the tangent weighting scheme, and for fixing the active use of the psi-0 triplets and of the quartet invariants. Each tangent trial may now be submitted to the RELAX procedure, a tool for moving to the correct position a well oriented but misplaced structural model. The resulting procedure shows surprising efficiency, testified by a wide set of applications. The experimental results have been compared with the tangent and VLD (vive la différence) approaches implemented inSIR2011.

Abstract
This paper deals with the flow dynamics around a competitive swimmer during underwater glide phases occurring at the start and at every turn. The influence of the head position, namely lifted up, aligned and lowered, on the wall shear stress and the static pressure distributions is analyzed. The problem is considered as 3D and in steady hydrodynamic state. Three velocities (1.4 m/s, 2.2 m/s and 3.1 m/s) that correspond to inter-regional, national and international swimming levels are studied. The flow around the swimmer is assumed turbulent. The Reynolds-averaged Navier-Stokes (RANS) equations are solved with the standard k-ω turbulent model by using the CFD (computational fluid dynamics) numerical method based on a volume control approach. Numerical simulations are carried out with the ANSYS FLUENT® CFD code. The results show that the wall shear stress increases with the velocity and consequently the drag force opposing the movement of the swimmer increases as well. Also, high wall shear stresses are observed in the areas where the body shape, globally rigid in form, presents complex surface geometries such as the head, shoulders, buttocks, heel and chest.

Abstract
The aim of this work is to specify which model of turbulence is the most adapted in order to predict the drag forces that a swimmer encounters during his movement in the fluid environment. For this, a Computational Fluid Dynamics (CFD) analysis has been undertaken with a commercial CFD code (Fluent). The problem was modelled as 3D and in steady hydrodynamic state. The 3D geometry of the swimmer was created by means of a complete laser scanning of the swimmer's body contour. Two turbulence models were tested, namely the standard k-epsilon model with a specific treatment of the fluid flow area near the swimmer's body contour, and the standard k-omega model. The comparison of numerical results with experimental measurements of drag forces shows that the standard k-omega model accurately predicts the drag forces while the standard k-epsilon model underestimates their values. The standard k-omega model also enabled to capture the vortex structures developing at the swimmer's back and buttocks in underwater swimming; the same vortices had been visualized by flow visualization experiments carried out at the INSEP (National Institute for Sport and Physical Education in Paris) with the French national swimming team.

Abstract
This work aims to study the usability of infrared thermography in swimming for the purpose of quantifying the influence of the swimming style on the cartographies of cutaneous temperatures of a swimmer. Only one subject took part in the experimental protocol, who was to accomplish a 4 x 100 m 4 medley. Thermal acquisitions followed by one period of recovery with return to thermal balance were carried out between particular strokes. IR thermography made it possible to discuss the influence of the swimming style on the distributions of cutaneous temperatures in various body zones. This process seems to be completely adaptable to the development of future statistical studies.

Abstract
BACKGROUND Over a 36-month study period, 10 nonconsecutive neuromuscular pediatric patients (6 infants, mean age 10.16 months, and 4 children, mean age 9.3 years) presenting with acute respiratory failure (ARF) were treated by noninvasive positive pressure ventilation (NPPV). All patients required immediate respiratory support and fulfilled our intubation criteria. OBJECTIVE The aim of the study was to verify if early NPPV was able to avoid endotracheal intubation and to improve both oxygenation and ventilation within 24 h from admission in this clinical setting. PATIENTS AND METHODS A prospective pilot study was carried out on neuromuscular patients admitted to the pediatric intensive care unit (PICU) of the Catholic University of Rome because of ARF and managed exclusively with NPPV for at least 24 h following admission. All patients were treated using a flow-triggered mechanical ventilator through a face mask or using the new helmet interface. RESULTS Eight patients were successfully ventilated during the observation period and 2 early failures occurred. Among children undergoing face mask NPPV, the PaO(2)/FiO(2) ratio increased from a median value of 75 (range 48-149) to 240 (range 133-385; p < 0.001) and 328 (range 180-371; p < 0.001) at selected time points (3 and 12 h after NPPV introduction, respectively); the alveolar-to-arterial oxygenation difference showed a similar trend, i.e. decreasing from a median value of 589 (range 213-659) to 128 (range 62-527; p < 0.01) and 69 (range 45-207; p < 0.001), respectively. Hypercarbic ARF resolved within 6 h from admission even in the most severe cases. CONCLUSIONS NPPV was a safe and effective first-line therapeutic approach in hypoxemic ARF children/infants with neuromuscular disease. It seems of importance to identify children with neuromuscular disorders who may be able to achieve residual ventilator-free breathing and to perform an NPPV trial avoiding tracheal intubation. Life-threatening respiratory distress and very young age should not preclude NPPV application in the PICU setting. The new helmet interface represents a promising tool for noninvasive ventilation in older children.

Abstract
This study deals with skin-friction drag analysis in underwater swimming. Although lower than profile drag, skin-friction drag remains significant and is the second and only other contribution to total drag in the case of underwater swimming. The question arises whether varying the thermal gradient between the underwater swimmer and the pool water may modify the surface shear stress distribution and the resulting skin-friction drag acting on a swimmer's body. As far as the authors are aware, such a question has not previously been addressed. Therefore, the purpose of this study was to quantify the effect of this thermal gradient by using the integral formalism applied to the forced convection theory. From a simplified model in a range of pool temperatures (20-30 degrees C) it was demonstrated that, whatever the swimming speeds, a 5.3% reduction in the skin-friction drag would occur with increasing average boundary-layer temperature provided that the flow remained laminar. However, as the majority of the flow is actually turbulent, a turbulent flow analysis leads to the major conclusion that friction drag is a function of underwater speed, leading to a possible 1.5% reduction for fast swimming speeds above 1m/s. Furthermore, simple correlations between the surface shear stress and resulting skin-friction drag are derived in terms of the boundary-layer temperature, which may be readily used in underwater swimming situations.

Abstract
INTRODUCTION Miller-Fisher syndrome (MFS) is a polyneuropathy with benign outcome characterized by ophthalmoplegia, limb ataxia and tendon areflexia. Impaired consciousness level and intracranial hypertension are very rare symptoms in MFS. CASE REPORT We describe the case of a 5-year-old girl who showed intracranial hypertension, transient coma and respiratory failure after mild head injury; moreover the patient showed mild ataxia, areflexia, ophthalmoplegia and autonomic disturbances. These symptoms were suggestive of MFS. Electrophysiologic studies and laboratory tests confirmed the diagnosis and immunoglobulins and steroids were given. The child showed a progressive clinical improvement and the final outcome was good. CONCLUSION This case, initially managed as trauma injury due to the presence of suggestive signs and clinical history, maskered an atypical presentation of Miller-Fisher syndrome, a rare disorder of central nervous system.

Abstract
We report two cases of critical presentation of a quite rare lung neoplasm of childhood. Presentation findings were at the extremes of the clinical pattern of this polymorphous neoplasm, ranging from an enormous solid mass causing airway compression and dislocation to an apparently benign cystic lesion discovered because of a tension pneumothorax. Both children were discharged from the pediatric intensive care unit and underwent appropriate surgical removal and oncological management. Congenital lung cysts, even asymptomatic, should not be underestimated and need elective surgical excision and histologic examination.

Abstract
AIM To evaluate the expression of neurotrophic factors (nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), glial-derived neurotrophic factor (GDNF)) and their association with the clinical-radiological characteristics and outcome of children with viral and bacterial meningoencephalitis (ME). METHODS Prospective observational clinical study performed on 13 children with ME and 12 controls with non-inflammatory obstructive hydrocephalus. Neurotrophic factor levels in the cerebro-spinal fluid (CSF) and plasma were measured using an immunoenzymatic assay. RESULTS High levels of NGF and BDNF were demonstrated in all patients, while GDNF levels did not undergo significant variations. NGF expression in the CSF was higher in viral ME than in bacterial ME and was correlated with CSF cellularity (particularly mononuclear cells). BDNF expression in the CSF was higher in bacterial ME than in viral ME and was correlated with CSF cellularity and blood platelet count. No relationships were noted between CSF protein or serum C-reactive protein levels and the expression of neurotrophic factors. Regarding clinical and radiological features, elevated NGF/BDNF levels in the CSF correlated with higher incidence of seizures and prolonged comatose state and with specific radiological lesions. No correlation was found between NGF/BDNF levels and final outcome. CONCLUSIONS The variations in neurotrophic factor levels may reflect an endogenous attempt at neuroprotection against biochemical and molecular changes during both viral and bacterial ME. The expression of these factors is likely to play a neuro-immunomodulatory or neurosurvival role in ME infections.

Abstract
We describe a case of pulmonary bleeding and subsequent acute respiratory distress syndrome (ARDS) in a 20-month-old female suffering from a typical postdiarrheal hemolytic-uremic syndrome (HUS). Acute renal failure was treated early by peritoneal dialysis. It is of interest to underline that thrombocytopenia or any coagulative impairment was absent when this complication occurred, and spontaneous diuresis recovery was ongoing. All examinations failed to identify a unique site of bleeding in the main stem bronchi or trachea. Complete renal and clinical recovery was obtained in spite of this very uncommon complication. Intensivists should be aware of this rare and potentially fatal complication of typical (D+)HUS.

Abstract
OBJECTIVE This manuscript examines the impact of mental health state and specific mental and physical disorders on work role disability and quality of life in six European countries. METHOD The ESEMeD study was conducted in: Belgium, France, Germany, Italy, the Netherlands and Spain. Individuals aged 18 years and over who were not institutionalized were eligible for an in-home computer-assisted interview. Common mental disorders, work loss days (WLD) in the past month and quality of life (QoL) were assessed, using the WMH-2000 version of the CIDI, the WHODAS-II, and the mental and physical component scores (MCS, PCS) of the 12-item short form, respectively. The presence of five chronic physical disorders: arthritis, heart disease, lung disease, diabetes and neurological disease was also assessed. Multivariate regression techniques were used to identify the independent association of mental and physical disorders while controlling for gender, age and country. RESULTS In each country, WLD and loss of QoL increased with the number of disorders. Most mental disorders had approximately 1.0 SD-unit lower mean MCS and lost three to four times more work days, compared with people without any 12-month mental disorder. The 10 disorders with the highest independent impact on WLD were: neurological disease, panic disorder, PTSD, major depressive episode, dysthymia, specific phobia, social phobia, arthritis, agoraphobia and heart disease. The impact of mental vs. physical disorders on QoL was specific, with mental disorders impacting more on MCS and physical disorders more on PCS. Compared to physical disorders, mental disorders had generally stronger 'cross-domain' effects. CONCLUSION The results suggest that mental disorders are important determinants of work role disability and quality of life, often outnumbering the impact of common chronic physical disorders.

Abstract
OBJECTIVE Comprehensive information about access and patterns of use of mental health services in Europe is lacking. We present the first results of the use of health services for mental disorders in six European countries as part of the ESEMeD project. METHOD The study was conducted in: Belgium, France, Germany, Italy, the Netherlands and Spain. Individuals aged 18 years and over who were not institutionalized were eligible for an computer-assisted interview done at home. The 21 425 participants were asked to report how frequently they consulted formal health services due to their emotions or mental health, the type of professional they consulted and the treatment they received as a result of their consultation in the previous year. RESULTS An average of 6.4% of the total sample had consulted formal health services in the previous 12 months. Of the participants with a 12-month mental disorder, 25.7% had consulted a formal health service during that period. This proportion was higher for individuals with a mood disorder (36.5%, 95% CI 32.5-40.5) than for those with anxiety disorders (26.1%, 95% CI 23.1-29.1). Among individuals with a 12-month mental disorder who had contacted the health services 12 months previously, approximately two-thirds had contacted a mental health professional. Among those with a 12-month mental disorder consulting formal health services, 21.2% received no treatment. CONCLUSION The ESEMeD results suggest that the use of health services is limited among individuals with mental disorders in the European countries studied. The factors associated with this limited access and their implications deserve further research.

Abstract
OBJECTS In literature, excessive perioperative haemorrhage and related haemodynamic instability have been described as major risk factors in hemispherectomy. In this report we analyse the impact of neurosurgical operation on both the haematological and coagulative patterns of these children, especially focusing on younger patients. METHODS From 1993 to 2003, 18 consecutive children suffering from intractable epilepsia and treated by hemispherectomy were admitted to the Pediatric Intensive Care Unit (PICU) of Catholic University Medical School, Policlinico Gemelli, Rome. Eight children had an entire hemisphere removed (anatomical hemispherectomy), whereas the remaining 10 underwent disconnective procedures (functional hemispherectomy) or cerebral cortex ablations (e.g. hemicorticectomy). Eleven out of these 18 children underwent hemispherectomy because of hemimegalencephaly (HME): their mean age was 14.5 months (range 3-56 months); non-HME patients underwent surgery for epileptogenic lesions involving the cerebral hemisphere to a great extent or diffusely. Data have been compared with an historical cohort of 13 children operated on before 1992 at the same institution comparable for age, aetiology of epilepsy and the modalities of surgical operation. CONCLUSIONS Blood losses and haemotransfusions showed a profound influence on the haematologic/coagulative status of the children operated upon. A strict correlation was demonstrated between estimated red cell volume (ERCV) loss and haemostatic impairment in this series. Recent surgical techniques appear to reduce blood losses and related haemocoagulative risks even in younger patients.

Abstract
OBJECTIVE To assess psychotropic drug utilization in the general population of six European countries, and the pattern of use in individuals with different DSM-IV diagnoses of 12-month mental disorders. METHOD Data were derived from the European Study of the Epidemiology of Mental Disorders (ESEMeD/MHEDEA 2000), a cross-sectional psychiatric epidemiological study in a representative sample of 21 425 adults aged 18 or older from six European countries (e.g. Belgium, France, Germany, Italy, the Netherlands and Spain). Individuals were asked about any psychotropic drug use in the past 12 months, even if they used the drug(s) just once. A colour booklet containing high-quality pictures of psychotropic drugs commonly used to treat mental disorders was provided to help respondents recall drug use. RESULTS Psychotropic drug utilization is generally low in individuals with any 12-month mental disorder (32.6%). The extent of psychotropic drug utilization varied according to the specific DSM-IV diagnosis. Among individuals with a 12-month diagnosis of pure major depression, only 21.2% had received any antidepressants within the same period; the exclusive use of antidepressants was even lower (4.6%), while more individuals took only anxiolytics (18.4%). CONCLUSION These data question the appropriateness of current pharmacological treatments, particularly for major depression, in which under-treatment is coupled with the high use of non-specific medications, such as anxiolytics.

Abstract
OBJECTIVE To describe the 12-month and lifetime prevalence rates of mood, anxiety and alcohol disorders in six European countries. METHOD A representative random sample of non-institutionalized inhabitants from Belgium, France, Germany, Italy, the Netherlands and Spain aged 18 or older (n = 21425) were interviewed between January 2001 and August 2003. DSM-IV disorders were assessed by lay interviewers using a revised version of the Composite International Diagnostic Interview (WMH-CIDI). RESULTS Fourteen per cent reported a lifetime history of any mood disorder, 13.6% any anxiety disorder and 5.2% a lifetime history of any alcohol disorder. More than 6% reported any anxiety disorder, 4.2% any mood disorder, and 1.0% any alcohol disorder in the last year. Major depression and specific phobia were the most common single mental disorders. Women were twice as likely to suffer 12-month mood and anxiety disorders as men, while men were more likely to suffer alcohol abuse disorders. CONCLUSION ESEMeD is the first study to highlight the magnitude of mental disorders in the six European countries studied. Mental disorders were frequent, more common in female, unemployed, disabled persons, or persons who were never married or previously married. Younger persons were also more likely to have mental disorders, indicating an early age of onset for mood, anxiety and alcohol disorders.

Abstract
OBJECTIVE The European Study of Epidemiology of Mental Disorders (ESEMeD) project was designed to evaluate the prevalence, the impact and the treatment patterns in Europe. This paper presents an overview of the methods implemented in the project. METHOD ESEMeD is a cross-sectional study in a representative sample of 21 425 adults, 18 or older, from the general population of Belgium, France, Germany, Italy, the Netherlands and Spain. The Composite International Diagnostic Interview (WMH-CIDI) was administered by home interviews from January 2001 to August 2003 using Computer Assisted Personal Interview (CAPI) technology. Data quality was controlled to ensure reliability and validity of the information obtained. RESULTS Response rate varied from 78.6% in Spain to 45.9% in France. Less than 4% of the individuals had errors in the checking procedures performed. CONCLUSION The sampling methodologies, comprehensive psychiatric instruments and quality control procedures used have rendered the ESEMeD database a unique and important source of information about the prevalence, the disability burden and unmet medical needs of mental disorders within Europe.
