Prenatal diagnosis of hypochondroplasia.

Prenatal diagnosis of a fetus at risk for hypochondroplasia, a short limb dwarfism condition similar to achondroplasia, was performed by ultrasound at 22 weeks' gestation. The limb bones were measured and shown to be decreased in length. The pregnancy was terminated. Post abortion X-ray did not show caudal narrowing in the lumbar spine but the pelvis had the features of hypochondroplasia.

[Determinants of compliance with antidepressive drugs].

A national survey was conducted in a representative sample of the general French population in order to assess antidepressant non compliance frequency and the factors that influence it. Two types of noncompliance were taken into account: 1) the premature interruption of the treatment; 2) the omission of doses. Data were collected by phone interview. Results show that 36.9% of the 423 included subjects (who represent 4.3% of the sample) were noncompliants (15.4% by treatment interruption and 21.5% by dosage modification). The two types of noncompliance have different risk factors. Treatment interruption was more frequent for patients with high level of schooling (OR = 2.5), in case of multiple take regimens (OR = 3), when the physician did not informed the patient about treatment (OR = 3.3) and when the patients' sources of information were exclusively non medical ones (OR = 3.7). Dosage modification was more frequent in female (OR = 2.1), when the treatment duration exceeded six months (OR = 2.5) and when the prescriber did not communicate with the patient relatives (OR = 1.8). The information delivered by the physician about the duration of the treatment was associated with the two types of compliance but with an opposite effect. This information has a protective effect on treatment interruption (OR = 0.5) but increases the risk of dosage modification (OR = 1.1).

[Cross-sectional study of the prevalence of adjustment disorder with anxiety in general practice].

Although Adjustment Disorder (AD) is considered a marginal diagnostic category by many clinicians and researchers, all the rare studies undertaken in the last decades indicate that the prevalence of this disorder is high in psychiatric settings, but has never been investigated in general practice. The purpose of this study was to evaluate the current prevalence of Adjustment Disorders With Anxiety (ADWA) in primary care settings and to describe the characteristics of the population, nature of the stressors and management of the disorder by General Practitioners (GPs). This French study involved 78 random liberal GPs, in 7 distinct regions (Paris, Lille, Bordeaux, Rouen, Dijon, Castres and Compiègne). GPs had to register all the consecutive attenders over 18 years old. For each physician, the registration period was over when 200 patients were registered, or 10 days of consultation were completed, or when 5 MINI had been performed. The average study period was 10 days per physician. At the first stage, they selected all the patients with psychological complaints, which were eventually associated to physical complaints. At the second stage, only the patients whose complaints were linked to a psychosocial stressor and without A1 and/or A2 DSM IV criteria for a Major Depressive Episode (MDE) were proposed the Mini International Neuropsychiatric Interview (MINI). The MINI is a brief structured clinical diagnostic interview that identifies the main axis-I DSM IV diagnoses in about 15 minutes. Before starting the study, all of the GPs participated in an intensive course on AD criteria recognition and were trained to use the MINI. The GPs registered a total of 7,759 consecutive patients. Twenty-two per cent (n = 1,719) of the patients reported psychological complaints, associated or not to physical complaints. Among them, 49% (n = 844) linked their complaints to identifiable psychosocial stressors. About half of the latter (n = 450) coded positive to A1 and/or A2 criteria for MDE. At the end, a total of 314 patients agreed to complete the MINI. Among the 1,719 patients with psychological complaints, the prevalence of ADWA eventually associated to other psychiatric disorders was 9.2%. The prevalence of "pure" ADWA was 4.5%. When considering the whole population of consecutive patients in primary care settings, the prevalence of pure ADWA was 1.0%. Patients suffering from pure ADWA were mostly women (66.7%), young patients (mean age: 42 years), with a professional activity. Patients had a psychiatric disorder history in 53.8% of the cases (mostly anxiety disorder). The main life events cited as being responsible for the disorder were work-associated problems (23.1%), followed by family illness (9.0%) and serious personal illness or accident (7.7%). The average duration of the disorder was 2.32 months. In 91% of the cases, GPs estimated that the patient required a pharmacological or psychological treatment. In most cases, they treated the patients with drug therapy (74.0%) associated with psychological support (counselling or psychotherapy, 76%). Anxiolytic agents were usually prescribed (64.9%), followed by antidepressants (10.8%) and hypnotics (8.1%). In conclusion, this first prevalence study of ADWA in general practice demonstrates that this disorder is frequent in primary care. It seems to be more present in patients who are of working age, especially women. ADWA would thus seem to preferentially affect active subjects. In most cases, GPs treat their patients with both psychological support and drug therapy. Anxiolytic is the elicited treatment of this disorder.

National campaign against hepatitis C in France (1999-2002).

Since 1988, several measures have been applied in France to control HCV infection. HCV seroprevalence in the adult population is estimated at 1.1% (500,000 to 650,000 persons) and the number of chronically infected at 400,000 to 500,000 persons. In 1994, most of them might not be aware of their infection. Blood products administration and injecting-drug use are identified as the main transmission routes. The national hepatitis C plan (1999-2002) was based on scientific data and developed after a consensus conference and several expert consultations. It involves six programs and quantified objectives: prevention of new infections, enforcement of screening access; improvement of care management; implementation of a surveillance system, clinical research and evaluation. Specific financial supports were attributed for the implementation of the plan. The 2001 progress report confirmed a major increase in national and regional actions. In 2000, considering the high proportion of persons still unaware of their infection (at least one third) and the increase of treatment efficacy, the target population of the screening strategy was considerably extended after scientific analysis. A national consciousness-raising campaign directed at general practitioners was launched in June 2000. In 2001, a media campaign directed to the general population was developed, in newspapers and on radio stations. Since the end of 1999, a national toll free phone number provides information to the public. In order to improve access to screening, a new regulation added HCV testing to the missions of anonymous and free HIV testing centres, as well as of family planning centres. The hepatitis C prevention strategy is still included in a national public health program and improved in view of its renewal.
