L’espace de la santé mentale : un paysage discursif et clinique en remaniement

Objectives

This paper introduces some epistemology about mental health developments and how it leads to reconsider the landscape of clinical practices.

Évolution de la mortalité par cancer après 65 ans en France métropolitaine (1973–2003)

Cancer mortality in the elderly has rarely been analyzed. It is most notably characterized by the level of diagnostic accuracy at ages prone to comorbidities. Trend analysis over the last thirty years and disparities in mortality have underscored the increasing cancer mortality in the over-65 age bracket as well as the relevance of local health context in understanding the significant differences seen throughout France.     

Septal rupture repaired in the acute stage of myocardial infarction. Clinical, hemodynamic and angio-coronarography findings in the evaluation of surgical risk

Between 1977 and 1987, 27 consecutive patients (16 men, 11 women, mean age 66 years, range 54 to 75 years) with ventricular septal rupture complicating acute myocardial infarction underwent surgical repair. The purpose of this retrospective study was to analyse the post-operative mortality factors from clinical, haemodynamic and operative data in all patients and also from coronary angiographic data in 23/27 patients whose haemodynamic status allowed this type of exploration. Seventeen patients (63 p. 100) died during the first post-operative month, 10 survived and were discharged. Factors that influenced the prognosis were: (1) inferiorly-located necrosis associated with a 75 p. 100 mortality rate (9 out of 12 patients), as opposed to 53 p. 100 (8 out of 15 patients) with anterior necrosis; (2) right ventricular dysfunction, observed in 83 p. 100 of patients with inferior necrosis and 53 p. 100 with anterior necrosis, which was responsible for 7 out of 9 deaths in the inferior necrosis subgroup and contributed to 3 out of 8 deaths in the anterior necrosis subgroup; this established a cause-effect relationship between right ventricular function and the overmortality of patients with inferior necrosis; (3) independently of the haemodynamic status, two- and three-vessel lesions (56 p. 100 of all lesions) which had an 84 p. 100 mortality rate as opposed to 40 p. 100 with one-vessel lesions; (4) the presence of a state of shock which was associated with a 78 p. 100 mortality rate as opposed to 55 p. 100 in patients without shock. We conclude that when permitted by the patient's haemodynamic status coronary angiography should be part of the pre-operative evaluation to assess the operative risk and guide the surgical procedure.     

Carbamazepine, diuretics, and hyponatremia: a possible interaction

Although carbamazepine is known to cause hyponatremia, no previous reports have indicated an interaction between carbamazepine and a diuretic. Two patients are described who were treated with this combination and developed symptomatic hyponatremia, which cleared when both drugs were discontinued in one patient and when the diuretic was discontinued in the second patient. The possible mechanisms of action of carbamazepine-induced hyponatremia are discussed.     

XPS analysis of poly[(3-hydroxybutyric acid)-co-(3-hydroxyvaleric acid)] film surfaces exposed to an allylamine low-pressure plasma

Homogeneous and stable layers were deposited through allylamine plasma polymerization (75 W, 100 Pa, 15 min) onto poly[(3-hydroxybutyric acid)-co-(3-hydroxyvaleric acid)] (91 : 9 wt.-%) (P(HB-co-9%HV)) film surfaces, XPS analysis using take-off angles of 20° and 70° and performed 10 days and 20 days after plasma treatment gives information on the composition (in atom%) of the modified surface: C, 62.74; N, 19.60; O, 17.65. The unexpected oxygen percentage is weaker if argon plasma pretreatment (25 W, 40 Pa, 5 min) is applied. Then, a succinct mechanism is proposed. The study of changes in element ratios and binding energy values shows that the majority of incorporated functional groups seem to be amide and imine groups.     

A preliminary study of serotonergic antidepressants in treatment of dysthymia

Rosenthal, Jesse et al. A Preliminary Study of Serotonergic Antidepressants in the Treatment of Dysthymia. Prog. Neuro-Psychopharmacol. & Biol. Psychiat. 1992, 16(6): 933–941.

1. 1. There is increasing evidence that antidepressants may alleviate symptoms of dysthymia, but few prior studies on selective serotonergic agents.

2. 2. Twenty patients meeting criteria for dysthymia, but not meeting criteria for major depression, received open label trials of a serotonergic antidepressant, either fluoxetine or trazodone.

3. 3. Seventeen (85%) completed three-month medication trials, and of these, twelve (70.6% of completers) responded to treatment. Seven (41.2% of completers) were still in remission on followup at five months.

4. 4. Both fluoxetine and trazodone were well tolerated in dysthymics, and showed similar short-term effectiveness in treating dysthymic symptoms.

Rashkind atrio-septostomy in incubators and neonatal intensive care units]

In 7 neonates with cyanotic heart disease, balloon atrial septostomy was performed in the neonatal intensive care unit under two-dimensional echocardiographic control. Trans-umbilical route was used with success in 6 neonates and percutaneous femoral vein in 1 neonate after failure of the trans-umbilical route. The mean transcutaneous oxygen saturation increase was 22%. No complications were observed. The average duration of the procedure was 25 minutes. Thus this technique is efficient, quick and easy to perform, allowing the procedure to be done under optimal environmental conditions in critically ill neonates.
