[Contribution of ABVD chemotherapy in refractory Hodgkin's disease. Study of 21 observations (author's transl)].

On a two years period, 21 patients with advanced Hodgkin's disease who failed usual therapeutic proceedings were treated by a sequential combination chemotherapy with adriamycin, bleomycin, vinblastine and dacarbazine (ABVD, first described by Bonadonna). Initially 16 patients among 21 had a disseminated disease with stage III B (9 obs.) or IV B (7 obs.). Previously all had been submitted, during a four years mean period, to multiple therapeutic trials always involving MOPP plus lymphoid irradiation and/or other combination chemotherapy. In 19 patients among 21, ABVD was decided because of persistent abdominal lymphoid and/or visceral localizations (liver: 6 obs.; lung: 4 9bs; épidural space: 1 obs.). In 12 patients, abdominal localizations were proved after delayed staging laparotomy. Immediate results with ABVD were: CR: 9 obs. (43%); PR: 5 obs. (24%); failure: 7 obs. (33%). With vinblastine interrupted by intermittent ABVD, 4 CR are persisting with a 8 to 23 months' follow up; among 5 patients who relapsed (3 to 24 months), 4 are still alive. After irradiation of résidual lesions, 4 PR among 5 are persisting with a 6 to 12 months' follow up. For the 21 patients, median survival has not been reached at 30 months.

[Heredity and childhood psychoses : histocompatibility antigens (HLA A and B) and early onset childhood psychoses (author's transl)].

We first consider current arguments in favor of a genetic etiology of childhood psychoses. These psychoses have to be separated in early psychoses (before age 5) and late onset ones (between 5 years and adolescence). These late onset psychoses appear to be genetically determined and related to schizophrenia, while early psychoses may be in part genetically related and subject to environmental factors. We also report a study on HLA in early onset psychoses in the North of France, which could not show any association between HLA system and the psychoses.

[Carbamazepine-fluvoxamine interaction. Consequences for the carbamazepine plasma level].

The current practices concerning psychotropic drugs use plasma levels for the therapeutic adaptation and for the prevention of overdose and side effects. We observed, among two patients treated with constant dosages of carbamazepine (CBZ), that the addition of fluvoxamine (FLV) has increased significantly plasma levels of CBZ. The first patient, suffering of an affective bipolar trouble (ICD-10), was hospitalized for major depression. His admission treatment was CBZ (800 mg/day) and cyamemazine (75 mg/day). The introduction of the FLV (200 mg/day) was justified by the symptomatology. Then, plasma levels of CBZ increased progressively. No clinic or biological side effect was observed. Rapidly, CBZ oral dosages were decreased, but the plasma levels of CBZ reached the therapeutic window only when the FLV prescription was definitively stopped. The other patient was hospitalized for an acute exacerbation of a paranoiac disorder. He was treated with haloperidol for this episode. For five years, he received CBZ for neuralgia of the Trigeminus. The emergence of a depressive disorder justified a FLV treatment. From the introduction of FLV, plasma levels of CBZ were significantly increased. The reduction, then the stop of the FLV treatment, has allowed the standardization of plasma concentrations of CBZ. Three similar studies were found in the literature. The danger of this interaction was notified in two studies (one case each). Furthermore, in the third study (three cases) was put forward the hypothesis of a new therapeutic pathway. this hypothesis was suggested by the fact that these two medications were proposed independently to treat impulsive behaviors.(ABSTRACT TRUNCATED AT 250 WORDS)

[Erythrocyte superoxide dismutase (eSOD) determination in positive moments of psychosis].

Dysregulation of free radical metabolism has been supposed to be involved in schizophrenia etiopathogeny. Recently, Wang et al. showed a red blood cell super oxide dismutase increase in positive schizophrenia (Crow's type I), but neither in negative schizophrenia (Crow's type II) nor in controls. The study included 28 in-patients suffering from acute positive psychosis who were compared with 15 controls. We confirmed the results of Wang. We found a significantly red blood cell Super oxide dismutase increase in positive psychosis, in comparison to negative psychosis and controls (p = 0.0001). This SOD increase was in relationship with the degree of clinical psychomotor excitement. After 21 days of neuroleptic treatment, SOD activity decreased and reached standard values. These results support the hypothesis of striking relationships between catecholaminergic hyper-metabolism and SOD increase, in positive psychosis. These could account for psychotic positive symptoms improvement with neuroleptic treatment, which blocks dopamine pathways.

[Acute catatonia and neuroleptic malignant syndrome. A case of infantile psychosis].

Similar clinical and biological features in lethal catatonia (LC) and neuroleptic malignant syndrome (NMS) suggest a relationship between both affections and common physiopathologic mechanisms. Pharmacological effects of several drugs--dopaminergic agonists, benzodiazepines, carbamazepine--suggest an impairment of several systems of neurotransmitters. We report the case of a young woman with infantile psychosis who developed catatonic syndrome worsened by neuroleptic treatment, arising the problem of the chronology of both affections. The evolution with treatment may partially explain the physiopathology. A 18-year old woman with an history of infantile psychosis, experienced insomnia, anorexia, paradoxical agitation developed after affective traumatism (mother's hospitalization). Chlorazepate (150 mg) remained inefficient and hospitalization was necessary. The patient was dumb, prostate in bed. She presented negativism, rigidity of the four limbs, catalepsia and hyperpyrexia (38.5 degrees C). Hepatic transaminases were increased (SGOT: 71 UI/l; N < 30). After cumulated dose of levomepromazine (100 mg) profuse sudation, thermic and cardiovascular instability, alteration of consciousness, major rigidity of limbs appeared. (Blood) hepatic transaminases and muscular enzymes increased. Bacteriological samples, cerebrospinal fluid analysis, CT-scan and EEG were normal. Within 48 hours after rehydratation and bromocriptine (30 mg per day) alteration of consciousness and autonomic disorders decreased but hyperpyrexia (38 degrees C) persisted. Biological parameters were normalized 10 days later. Negativism and psychomotor inertia remained. Lorazepam (3 mg per day) failed to be clinically beneficial. On carbamazepine (600 mg per day) she started speaking and moving spontaneously. Catalepsia disappeared but rigidity and anorexia persisted. Electroconvulsivotherapy (ECT) was necessary. After 2 shocks she started standing up, walking, taking food and speaking fluently.(ABSTRACT TRUNCATED AT 250 WORDS)
