Disability and quality of life impact of mental disorders in Europe: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD) project

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.

Use of mental health services in Europe: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD) project

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.

Psychotropic drug utilization in Europe: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD) project

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.

Prevalence of mental disorders in Europe: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD) project

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.

Sampling and methods of the European Study of the Epidemiology of Mental Disorders (ESEMeD) project

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.

12-Month comorbidity patterns and associated factors in Europe: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD) project

OBJECTIVE

Comorbidity patterns of 12-month mood, anxiety and alcohol disorders and socio-demographic factors associated with comorbidity were studied among the general population of six European countries.

METHOD

Data were derived from the European Study of the Epidemiology of Mental Disorders (ESEMeD), a cross-sectional psychiatric epidemiological study in a representative sample of adults aged 18 years or older in Belgium, France, Germany, Italy, the Netherlands and Spain. The diagnostic instrument used was the Composite International Diagnostic Interview (WMH-CIDI). Data are based on 21 425 completed interviews.

RESULTS

In general, high associations were found within the separate anxiety disorders and between mood and anxiety disorders. Lowest comorbidity associations were found for specific phobia and alcohol abuse-the disorders with the least functional disabilities. Comorbidity patterns were consistent cross-nationally. Associated factors for comorbidity of mood and anxiety disorders were female gender, younger age, lower educational level, higher degree of urbanicity, not living with a partner and unemployment. Only younger people were at greater risk for comorbidity of alcohol disorder with mood, anxiety disorders or both.

CONCLUSION

High levels of comorbidity are found in the general population. Comorbidity is more common in specific groups. To reduce psychiatric burden, early intervention in populations with a primary disorder is important to prevent comorbidity.

Vanguardia en el estudio del córtex auditivo. demostración de su activación mediante resonancia magnética funcional

PURPOSE

The purpose of this preliminary study has been to demonstrate and investigate the activation patterns of the primary auditory cortex (Heschl's gyrus = HG) using functional magnetic resonance imaging (fMRI).

MATERIAL AND METHODS

A 2500 Hz tone stimulus was delivered monoaurally to the right and left ear of 15 normal-hearing right-handed volunteers in 20-second on-off cycles. FMRI data were obtained using a 1.5-Tesla scanner and processed with SPM2.

RESULTS

Activated pixels were identified in the transverse temporal gyrus (Heschl's gyrus) of both hemispheres in response to pure tone stimuli using cross-correlation analysis (P < 0.001). Bilateral hemispheric activation was observed in all subjects and there was a trend towards contralateral HG activation to the stimulated ear.

CONCLUSION

These results demonstrate directly that fMRI is a new and useful imaging technique to study the complex auditory cortex and it will have potential clinical applications in the next future.

[Sino-nasal endoscopic surgery in fungal sinusitis. Our experience]

Fungal sinusitis is a rare entity which has increased amongst immunocompromised individuals. Records of thirteen patients treated of fungal sinus disease between 1995 and 2001 were reviewed. Histopathological studies demonstrated infection due to Aspergillus in eight patients and due to Mucormycosis in five patients. The surgical debridement via endoscopic sinus surgery was the essential part of the management. The follow-up is 12-72 months (mean 29.08). The main clinical findings and a review of the literature are presented. We conclude that endoscopic sinus surgery is the treatment of choice for fungal sinusitis except in advanced cases of mucormycosis in which a combined approach is still necessary together with intravenous antifungal drugs (amphotericin B).

[Landau kleffner syndrome]

INTRODUCTION

The Landau Kleffner syndrome (SLK) is associated with paroxystic alterations of the electroencephalogram which are intensified during sleep, with acquired aphasia and epilepsy, in 75 83% of the cases. The syndrome is associated with other features, such as personality disorders presenting as autistic behaviour, cognitive regression and in some cases, motor dysfunction. The epileptic activity appears to be responsible for the disorder. Treatment with anti epileptic drugs is ineffective in many cases, although there may be periods of spontaneous improvement, or there may be permanent sequelas of language. Design. A systematic revision of one case.

CASE REPORT

A five year old boy with no previous clinical history had, at the age of four years, presented with behaviour changes and aphasia, accompanied by paroxystic changes on the EEG and nocturnal polysomnogram. On cranial CT there was a mid line cyst. He had had no seizures. Treatment. Treatment with carbamazepine led to clinical improvement in behaviour, reduction in the paroxysms and appearance of sleep spindles, but little effect on the degree of aphasia.

CONCLUSIONS

The case described is a variant of SLK, with no epileptic seizures, some improvement on carbamazepine and a mid line cyst.

Percutaneous endoscopic gastrostomy in head and neck cancer patients

OBJECTIVE

To present our experience with the indications and complications of percutaneous endoscopic gastrostomy (PEG) in head and neck cancer patients.

MATERIALS AND METHODS

In a retrospective study of the patients treated, we reviewed the records of 43 patients diagnosed with head and neck cancer at the Otorhinolaryngology Department, in which a PEG was performed by the Unit of Digestive Endoscopy.

RESULTS

All cases had squamous cell carcinoma. Larynx was the most frequent primary site, with 21 cases (49%), followed by hypopharynx, 12 patients (28%). Indications for PEG were: dysphagia (53.5%) and pharyngocutaneous fistula (43.5%). The most frequent complication was a local infection.

CONCLUSION

PEG is a good choice for long-term enteral feeding in head and neck cancer patients due to its low complication rate and easy handling.

[Post traumatic partial seizures]

INTRODUCTION

Post traumatic epilepsy represents 4% of the prevalence of the disorder and is one of the sequelas which is most difficult to prevent. Risk factors have been described to predict the appearance of seizures.

CLINICAL CASE

A seven year old boy with a severe head injury was admitted to the Intensive Care Unit. On neuroimaging studies there were multiple foci of contusion, mainly in the left hemisphere, and blood in the III and IV ventricles and frontal horn of the left lateral ventricle. The patient had severe sequelae of head injury with a right spastic hemiplegia and hemiparesia with hypertony of the left side, together with complete blindness of both eyes due to bilateral atrophy of the optic nerve. Serial EEG were done, in which a recording showed alternating periods of hypervoltage grapho elements superimposed on a trace of very low voltage, with continuous activity of low voltage and low frequency. There were no grapho elements with acute morphology. However, the patient had a first partial seizure a year and a half after his head injury. On the EEG an epileptogenic focus was identified in the left hemisphere. Within two years of his head injury he had seven seizures. He had not received prophylactic antiepileptic treatment after the head injury.

CONCLUSIONS

We report a case of epilepsy secondary to a head injury, in which the first seizure occurred one and a half years after injury. In view of the risk factors, we discuss whether prophylactic anti epileptic treatment might have been beneficial.

Treatment of rhinocerebral mucormycosis by combination of endoscopic sinus debridement and amphotericin B

Rhinocerebral mucormycosis (RCM) is an aggressive fungal infection with a high mortality rate. It frequently develops in patients with uncontrolled diabetes mellitus or immunocompromised patients. RCM typically presents in a rapidly fulminant manner with headache, fever, mucosal necrosis, and ophthalmic symptoms. Although the definitive diagnosis is achieved by histopathological examination, computed tomography (CT) scanning and magnetic resonance (MR) are the best imaging procedures in early diagnosis to assess the extent of the disease.

Co-morbidity in Gaucher's disease results of a nationwide enquiry in Spain

SHORT INTRODUCTION

Gaucher's disease (GD) is an autosomal recessive disease produced by mutations of the Glucocerebrosidase gene. Carriers are considered to be healthy subjects because there is no manifestation of the disease, but they show signs of macrophage disfunction. The aim of the study was to determine if GD patients and non affected carriers risk suffering other diseases when compared to healthy non-carrier relatives.

MATERIAL AND METHODS

DESIGN

Epidemiologic study of historic cohorts. The fact that they have one or two mutated alleles has been considered to be the risk factor leading to other conditions (Dementia, Parkinson disease, Ischemic stroke, Ischemic heart disease, Non rheumatic valvular disease, Cancer hematological and non-hematological, Pulmonary fibrosis, Tuberculosis, Gallstones and Schizophrenia). All people, patients, carriers and healthy controls shared the same genetical background and environmental influence. - Patients and relatives enrolled on the Spanish Gaucher Disease Registry were evaluated.

STATISTICS

For the Relative-Risk calculation the Mantel-Haenszel test was applied. Yates' correction was used when size sample was too small. A value of p <0.05 was accepted for statistical significance.

RESULTS

370 people, from 79 different families, were surveyed. We received evaluable information from 45 families (56%), totalling 258 people (69%): 59 healthy subjects (Mean age 32. 20, RANGE: 10-85; M 57.63%/F 42.37%), 132 carriers (Mean age 35.91, RANGE: 1-79; M 56.82%/F 43.18%) and 67 patients (Mean age 32.16, Range: 1-76; M 44.78%/F 55.22%. - Relative Risk of suffering any disease with regard to Gaucher's status: Patient vs Healthy 9.69 (95% Confidence interval [CI] 2.00-63.99; p 0.0006). Patient vs Carrier 3.74 (CI 1.53-9.27; p 0.001); Carrier vs Healthy 2.59 (CI 0. 52-12.50; p 0.21). Relative Risk of suffering any disease with regard to sex was 3.96 for female patients (CI 1.01-16.75; p 0.02) and 1.34 for female carriers (CI 0.27-6.75; p = 0.68).

CONCLUSION

As a group, Gaucher's patients seem to have a greater risk of suffering other common unrelated diseases than carriers or healthy relatives. This excess of risk is particularly higher among female patients and can not be explained in terms of differences in age. Carrier status doesn't seem to highten the risk of suffering other diseases.

[Which are the true incidence rates of primary hematological disorders acquired in our population?]

PURPOSE

To define demographic and epidemiological characteristics of primary haematological disorders (PMHD) in patients referred to a haematology department in 1,240 beds general hospital.

PATIENTS AND METHODS

PERIOD OF STUDY

01/94-12/94. We have performed a study in patients older than 14, to determine the age adjusted incidence rates of PHD in the assigned population: 439,279 inh (M: 210,139; F: 229,140), with a negative-vegetative growth (-1.39/10(3) inh/y). A total of 1,242 new cases was received, 302 of them were diagnosed of PHD. Epidemiological method: incidence rates (IR), age and sex adjusted incidence rates (AIR), truncated standardized incidence rates (TSIR) and confidence interval (CI) were calculated.

STATISTICAL METHOD

Normal distribution, descriptive and frequency distribution analysis were performed along with chi 2 test.

RESULTS

Demographic data: mean age (+/- SD): 63.54 y +/- 15.81; range 19-92. M/F: 177/125, males mean age 62.85 +/- 16.29, females: 64.52 +/- 15.11. The PHD distribution was: MGUS 84 cases; NHL 57; MDS 33; CLL 26; CMPD 26; MM 21; HD 14; AL 11; ITP 10; CML 9; AIHA 5; hypoplastic anaemia 3; and cryoglobulinaemia 3. AIR (cases/10(5) inhab/y): Consulting rate 261.79. The PHD incidence rate was 31.00 (M: 38.01; F: 25.51). In patients under 60 y the AIR of PMDH was 31.31 (M: 36.42, F: 26.25), and in those older than 60 y the AIR was increasing, with 178.86 (M: 247.21, F: 128.52). The AIR for subtypes was: MGUS, 8.01 (M: 3.56, F: 1.93); CLL 2.28 (M: 2.69, F: 1.95); CMPD 3.17 (M: 2.83, F: 3.51); MM 1.92 (M: 2.43, F: 1.49); HD 2.27 (M: 3.54, F: 1.04); AL 1.41 (M: 1.54, F: 1.30); ITP 1.15 (M: 1.20, F: 1.12); CML 1.09 (M: 1.19, F: 1.01); AIHA 0.61 (M: 0.55, F: 0.69); hypoplastic anaemia 0.24 (M: 0.19, F: 0.30); cryoglobulinaemia 0.34 (M: 0.55, F: 0.14).

REMARKS

The elderly have increased incidence of PHD. The AIR is higher in males and in older than 60 y, unless for CMPD. Most frequent PHD were MGUS and NHL.

Quantitative ELISA for mouse monoclonal antibody determination in culture supernatants and in human serum

An ELISA has been set up for quantifying mouse monoclonal antibodies in culture supernatant. The assay includes rabbit anti-mouse IgG antibodies chromatographycally purified. This preparation was used as coating and as conjugated antibodies in the ELISA. The assay can detect IgG1 with sensitivity of 0.2 ng/mL, IgG2a (0.85 ng/mL), IgG2b (0.13 ng/mL), and IgG3 (3.19 ng/mL) in culture supernatants. The effective working range was from subnanogram per mL quantities to 30 ng/mL by using a computer statistical program. Variation coefficient of ELISA was below 7%. Correlation estimates with a similar ELISA using commercial reagents were performed for each mouse antibody subclass. The assay was able to detect the four mouse monoclonal antibody subclasses in pure human serum as compared with the same ELISA using commercial antibodies. A 24-h pharmacokinetic profile of 1 patient treated with an IgG2a monoclonal antibody is presented.

Vibrio furnissii isolated from humans in Peru: a possible human pathogen?

During a cholera surveillance programme, Vibrio furnissii was isolated in late January and early February 1994 from stool samples collected from 14 persons of whom six had diarrhoea. The remaining eight persons were healthy family members or neighbours to cholera cases. No common source of infection was found. Strains isolated from stool samples each showed typical biochemical reactions of V. furnissii including gas production. Each isolate, except one, agglutinated O-antisera yielding a total of eight different serotypes. Most isolates were sensitive to 10 antibiotics tested, except to ampicillin and the vibriostatic agent O/129 (10 micrograms). Eight of 14 (57%) strains carried plasmids in the size range 2.6-88 kb, however, no correlation was found between antibiotic susceptibility patterns and plasmid content. Altogether, seven closely related HindIII ribotypes were observed among the 14 V. furnissii isolates studied. V. furnissii strains isolated from family members and other persons living close together often showed different ribotypes suggesting that the isolation was not associated with neighbourhood. Serotyping, plasmid profiling and ribotyping revealed a high strain diversity within V. furnissii, however, the importance of V. furnissii as an enteric pathogen remains to be elucidated.

[A new method of administration of budesonide powder for the treatment of allergic rhinitis]

The efficacy and safety of a new device for administering powdered budesonide in allergic rhinitis was evaluated. This method eliminates the disadvantages of traditional preparations and improves dosing and administration, even at low nasal flow rates. A randomized, controlled, single-blind study was made in 66 patients with allergic rhinitis, half of whom were assigned to the experimental treatment (powdered budesonide) and half to a standard aerosol. Results showed that both preparations were very effective (p < 0.01) in controlling rhinitis symptoms and not significantly different. However, the overall patient evaluation was significantly better (p < 0.01) in the group treated with powdered budesonide. Both treatments elicited a similar tolerance, although tolerance of powdered budesonide was slightly better. To conclude, treatment with the new powdered budesonide dispenser was as effective and well-tolerated as standard treatment, and better accepted by patients.

[The study of suicides and homicides in Spain. Years 1980-1990]

A descriptive epidemiological was carried out in order to evaluate true scope of the problem of suicides and homicides in Spain. These two items were considered individually. With regard to the cases of suicides and homicides published in Causes of Death Spain, the mortality rates, tendency and potential years of life lost (PYLL) were calculated. We have found that the suicides rates are higher than the homicide and both are higher in men than in women. The provinces having the highest suicide rates are: La Rioja, Ceuta and Melilla, Asturias and Galicia. Those have the lowest Castilla-León. By means of the tendency study, we have noted a greater increase in Barcelona, Madrid and Valencia for the period 1980-90. Regarding homicides, the only provinces showing statistically significative values are Jaen, Las Palmas and Guipuzcoa. The provinces with highest rates of PYLL, in men, were Galicia, Asturias and Navarra; were observed in the women of Cantabria and Madrid in the case of suicides, and Castilla-La Mancha, Asturias, Ceuta and Melilla in case of homicides.
