[Therapeutic strategies in the first psychotic episode]. / Les stratégies thérapeutiques face à un premier épisode psychotique.

A first psychotic episode includes a wide range of disorders with different outcomes: schizophrenia, bipolar disorder, schizophreniform disorder, schizoaffective disorder, drug-induced psychosis, brief reactive psychosis, organic psychoses and delusional disorder. The course and outcome of a first psychotic episode is greatly dependent on its initial management. Major clinical, etiopathogenic and therapeutic advances have been achieved in this field and have allowed specific management strategies to be adopted. The primary task of therapists involved in the management of patients who have experienced a first episode of psychosis is promotion of recovery and prevention of secondary morbidity, relapse and persistent disability. The main guidelines of an early psychosis management are:--to keep in mind that early psychosis is not early schizophrenia. Thus, clinicians and therapists should avoid an early diagnosis of schizophrenia. Diagnosis in early psychosis can be highly unstable. A diagnosis of schizophrenia, with its implications of pessimism, relapse and disability, does not contribute anything positive in terms of guiding treatment. On the contrary, such a diagnosis may damage the patient and family by stigmatizing them and affecting the way they are viewed and managed by healthcare professionals.--To integrate biological, psychological and social interventions: effective medications is useful in reducing the risk of relapse, but is not a guarantee against it. Psychological and social interventions can greatly help promote recovery.--To tailor the various strategies to met the needs of an individual: as an example, it is important to formulate appropriate strategies for the different stages of the illness (prodromal phase, acute phase, early recovery phase and late recovery phase) because patients have different therapeutic needs at each stage.--In the acute treatment, not to concentrate on short-term goals in indicating antipsychotic treatment: prescribing principles for first-episode psychosis are to maximise benefit and minimise side effects because the first experience of medication may influence a patient's future attitudes of therapy of all types. Effective strategies which may reduce long-term morbidity and improve recovery are currently available but their implementation is too often delayed. The time lag between the onset of symptoms and the start of treatment can be many months or years and this delay can have serious consequences. The critical period of the first 2-5 years after the first psychotic episode is a time of maximum vulnerability and of maximum opportunity. Consequently, actions should be undertaken to promote early recognition and assistance in psychotic disorders: understanding of the factors that may cause delay in treatment can help minimise this problem and lead to the initiation of appropriate treatment at the earliest opportunity. Training the general practitioners who have an important part to play in the early recognition is also of crucial importance.

[Weaver's syndrome. Apropos of a new case]. / Le syndrome de Weaver. A propos d'un nouveau cas.

We report a new case of Weaver syndrome in a male infant. This clinical entity is rare and was first described in 1974. Patients exhibit accelerated growth and skeletal maturation, craniofacial dysmorphism, and widening of the distal femoral metaphyses. Differential diagnosis should mainly out-rule Marshall-Smith syndrome that includes facial dysmorphism, accelerated skeletal maturation, growth deficiency, and mental retardation. Our case is unusual in that respiratory disorders, a feature often seen in Marshall-Smith syndrome but occurring rarely in Weaver syndrome, were present, as well as congestive cardiomyopathy that has apparently never been described in this syndrome, and major macrocrania.

[Thrombosis of the right ventricle in 2 infants with myocardiopathy]. / Thrombose du ventricule gauche au cours d'une myocardiopathie chez deux nourrissons.

We report two cases of left ventricular thrombosis in infants with myocardiopathy. Patients were aged ten and twelve months respectively. Two-dimensional echocardiography, performed because of the development of heart failure, evidenced an echogenic image within the left ventricle and significant dilatation of the left ventricular chamber. One patient developed a peripheral arterial thrombosis that resolved under anticoagulant therapy. The intracardiac thrombus disappeared under anticoagulant therapy after one month in one patient and six months in the other. Pathophysiology of the left ventricular thrombosis is discussed; the dilatation of the left ventricle apparently played a significant role. We emphasize the value of early initiation of preventive anticoagulant therapy in patients with myocardiopathy.

Conduction disturbances after correction of tetralogy of Fallot: are electrophysiologic studies of prognostic value?

Late complete heart block may occur after correction of tetralogy of Fallot. Whether postoperative electrophysiologic studies can identify patients at risk of developing this conduction disturbance is unknown. In this study, 57 children who underwent electrophysiologic investigation after correction of tetralogy of Fallot were followed up for 1 to 13 (mean 6.5) years after the investigation. One late death and two cases of late complete heart block occurred. The late death was due to ventricular arrhythmia and not to a conduction disturbance. The cases of late heart block occurred 2 and 5 years, respectively, after electrophysiologic study, and in both cases the patient had a prolonged HV interval; in one patient progressive lengthening of the HV interval could be demonstrated at two subsequent studies 1 year apart. Another five patients with a prolonged HV interval had normally conducted sinus rhythm up to 11 years after study. Atrial pacing at increasing rates (up to the occurrence of second degree atrioventricular block) during electrophysiologic study was the best means of predicting late heart block: of three patients with block below the bundle of His occurring at pacing rates less than 180/min, two developed late complete heart block. Thus, electrophysiologic testing of the conduction system after correction of tetralogy of Fallot is useful in predicting late complete heart block and should be performed in patients with a history of transient heart block after surgery and in those with a prolonged PR interval.

Cardiac valve prostheses, anticoagulation, and pregnancy.

The course of 76 pregnancies is reported in 51 women who became pregnant after replacement of one or more heart valves. Age at conception ranged from 17 to 39 years (mean 25). There have been 71 deliveries and five women are still pregnant at the time of writing. In the 71 pregnancies, oral anticoagulants were given during 53, heparin during five, and no anticoagulants during 13. Fetal complications consisted of 12 spontaneous abortions (eight in pregnancies in which oral anticoagulants were given, three in which heparin was given, and one in which no anticoagulants were given), of 12 premature deliveries with seven stillbirths (three on oral anticoagulants and four without anticoagulants), and there were three neonatal deaths (in all all three instances oral anticoagulants had been given during pregnancy). The maternal complications were as follows. Two women with mitral valve prostheses on heparin had thromboembolic episodes. Four women on oral anticoagulants died and 11 developed haemorrhage or systemic embolism. Two of the deaths were caused by bacterial endocarditis, one was the result of obstruction of a mitral valve prosthesis, and one was due to haemorrhage. One patient developed pulmonary oedema during delivery which rapidly resolved. Seven patients had uterine bleeding after delivery (three of them were on heparin and one was on an antiplatelet agent).

[Heart valve prostheses in children with reference to 95 cases]. / Prothèses valvulaires chez l'enfant. A propos de 95 cas.

Over a 10 year period, 95 children aged 15 years and less underwent replacement of one or several of their heart valves, usually by a Starr-Edwards ball prosthesis. The predominant pathology was rheumatic heart disease and the most commonly affected valve was the mitral. Severe symptomatology, heart failure, cardiomegaly and high wedged-capillary and pulmonary arterial pressures were practically constant findings. Operative mortality was low (3.2%) and the long-term mortality was 10 patients. With an average follow-up of 40 months, results were excellent in the great majority of patients, with complete regression of symptoms, cardiomegaly and high capillary and pulmonary arterial pressures. Anticoagulant therapy was not systematic and only half the series were so treated. Thromboembolic complications were rare, 5.5% patients, but only affected those without anticoagulant therapy. The problems of evolving rheumatic disease and, above all, of tricuspid incompetence, the persistence of which after surgery on the mitral valve seems to be a sign of advanced myocardial damage, are discussed.

[Heart valve prosthesis and pregnancy]. / Prothèses valvulaires cardiaques et grossesse.

Sixteen pregnancies were followed up in 13 patients with prosthetic heart valves: 8 pregnancies went to term under oral anticoagulation, 4 under heparin and 4 without anticoagulation. 9 healthy normal children were delivered; there were 2 still births and 5 abortions. On the maternal side 3 haemorrhages and thromboembolic episodes which involved 2 patients on heparin, one of whom died, were observed. The following points are apparent from our observations and a review of the existing medical literature: --the risk of thromboembolism is not increased. The marked clotting tendency of maternal blood post-partum contraindicates the withdrawal of anticoagulants during this critical period; --haemorrhagic complications are common with anticoagulants; --foetal loss is greatly increased; --the teratogenecity of vitamin-K antagonists is certain, but the risk is small. The problems of anticoagulation are discussed; theoretically heparin should be given during the 1st trimestre and from the 38th week to the second post-partum week. The patients should be closely supervised by both obstetrician and cardiologist and hospitalisation is advised for the last month of pregnancy. Normal vaginal delivery is usually possible.

[Mitral commissurotomy in children. Apropos of 100 cases]. / Commissurotomie mitrale chez l'enfant. a propos de 100 cas.

We report 100 cases of mitral commissurotomy in children, 15-years-old or less, suffering from rheumatic mitral stenosis. Mitral stenosis in children is characterised by the severity of functional impairment and the considerable radiological, electocardiological and haemodynamic changes, with pulmonary arterial hypertension which is always present and often well marked. The early results of mitral commissurotomy are very satisfactory with clinical improvement and a low mortality. But, in the long term, we have seen progressive deterioration in the clinical state of these patients resulting from re-stenosis or from the progression of another valve lesion. Three problems have been discussed. First, the progression of the rheumatic process which seems to account to a large extent for the late failures of mitral commissurotomy in children. Secondly, the problem of tricuspid insufficiency, which is often associated with mitral stenosis in childhood and which usually disappears during the post-operative period. Finally, the problem of pre-capillary pulmonary arterial hypertension which always showed a tendency towards regression.
