[Acute voluntary or accidental disopyramide poisoning. A multicentric study of 106 cases (author's transl)].

Between 1972 and 1978, 106 case-records of disopyramide poisoning were collected from French anti-poison center. Acute intoxication was voluntary in 90% of the cases and occurred in young adults. Clinical symptoms appeared early and consisted mostly of cardiovascular disorders, which were present in 60 patients: cardiogenic shock (24 cases), circulatory arrest (17 cases), atrio-ventricular block (21 cases), intraventricular block (24 cases) and severe ventricular arrhythmia (12 cases). The toxic dose in otherwise healthy adults was 1,5 g and the mortality rate was high (12,2%). An analysis of therapeutic measures and outcome indicated that the best treatment consists of early gastric lavage, cardiorespiratory manoeuvres, electric heart stimulation, administration of sodium lactate in cases with intraventricular conduction disturbances and isoprenaline in cases with cardiogenic shock.

Light and electron microscopic study of ear cartilage in a case of relapsing polychondritis evolving under corticoid treatment.

Light and electron microscope studies of the ear cartilage in a patient with relapsing polychondritis (RP) under corticoid treatment are reported. Unilateral auricular deformation evolved without inflammatory epidoses and the lesions consisted mainly of marginal erosions filled with fine collagen fibrils and containing degenerating perichondrial cells in their basal parts. Degenerative cells were scattered throughout the perichondrium, but cartilage erosions only occurred when numerous cells were affected in a same area. Cartilage outside the eroded zones did not seem to be modified. Cartilage lesions thus appear to be a result of a chondrocyte renewal defect leading to loss of proteoglycans and elastic fibers, with only collagen remaining. These data suggest that inflammation is probably not the initial pathogenic process responsible for cartilage injury in RP, but that a metabolic defect in perichondrial cells might be involved.

[Acute post-operative peritonitis in gastro-enterological surgery. Opinion of the intensive care unit (author's transl)].

Acute purulent post-operative peritonitis is highly severe and difficult to diagnose. Six symptoms have a real prognostic value: shock, acute renal insufficiency, respiratory failure, jaundice, acidosis and septicaemia. If more than three of these signs of severity coexist, the mortality rate reaches nearly 100%. A patient with evidence of acute diffuse post-operative peritonitis must be operated on after a short preoperative treatment to restore a situation altered by shock, renal failure and pulmonary edema. Antibiotic agent alone, though necessary, cannot bring recovery. The maintenance of high nutritional intake for excess caloric expenditure is essential. The effects of the early decision of a surgical reintervention are studied in 27 patients with only two recoveries.

[Immunoallergic acute haemolysis, thrombocytopaenia and acute renal insufficiency due to treatment with catechines (author's transl)].

The authors report the case of a 25-year-old patient who during discontinuous treatment with a venotropic agent containing catechines suffered from intravascular haemolysis, thrombocytopaenia and acute renal failure, the course of which was favourable with treatment by haemodialysis. Renal biopsy revealed lesions of acute tubulonephritis with a slight interstitial reaction but without immune deposits. The demonstration in the serum and on the red cells of the patient of anti-catechine antibodies confirmed the immunoallergic nature of the haemolysis. The existence of crossed allergy with another venotropic agent, leucocyanide, led to suspicion of the localisation of the antigenic site on the 3-4 dihydroxyphenyl portion of the catechine molecule.

Acute immunoallergic hemolysis with acute renal failure induced by catechin.

A young woman, 25 years old, being treated for her veinous system with EucatexR (a drug including catechins) presented an acute intravascular hemolysis with an acute renal failure. The finding of anti-Eucatex and anti-catechins antibodies in the serum and on the red cells of the patient proved the immuno-allergic nature of this hemolysis. A renal biopsy showed lesions of acute tubular nephritis but no immune depots. The patient recovered after a treatment by hemodialysis.

Accidental acute mercury vapor poisoning.

Accidental acute mercury vapor poisoning in three persons is reported. Three hours after exposure, symptomatology began by chills, vomiting, diarrhea and chest pain. Two patients, respectively 67 and 77 year old, presented severe pulmonary edema, then neurological symptoms with tremor and coma. This toxic pulmonary edema, which entailed artificial ventilation, was followed in both cases by an acute interstitial pulmonary fibrosis which led to death respectively after six and sixteen days. In the third case (a thirty eight year old patient) a skin rash, erythematous and pustuliform was observed. Analysis for total mercury by flameless atomic absorption showed very high mercury levels in blood and urine of the three patients. The effect of treatment by Dimercaptopropanol on renal excretion of mercury was studied. Optic and electron microscopy of the lung of the two patients who died showed the pulmonary changes of acute interstitial fibrosis.

[Inappropriate secretion of anti-diuretic hormone in a case of intermittent acute porphyria (author's transl)].

The authors report the case of a patient who presented, during two exacerbations of intermittent acute porphyria, a grave psychiatric syndrome secondary to severe hyponatraemia. The later was due to inappropriate secretion of anti-diuretic hormone confirmed by laboratory tests and the stimation of anti-diuretic activity in the urine. The course was favourable under the effects of symptomatic treatment including sodium supplements and fluid restriction. The anti-diuretic syndrome disappeared on each occasion without sequelae at the time of regression of the exacerbation of porphyria.

Acute interstitial pulmonary fibrosis. Comparative light and electron microscopic study of 19 cases. Pathogenic and therapeutic implications.

Comparative light and electron microscopic studies of the lung were performed in 19 cases of diffuse acute interstitial fibrosis with various etiologies. Our observations emphasize the relation between hyaline membranes (HM) and the evolution of fibrosis. HM formation is due to fibrinous exudates and epithelial necrosis. This phenomenon recurs during the evolution of the disease and appears to be responsible for new waves of fibrosis. Its pathogenesis (humoral or neurovascular ...) remains hypothetical. Modifications of the alveolar epithelium consecutive to septal fibrosis can be clearly distinguished from "fibrinoid necrosis" -type lesions, which results in HM. The formation of HM is accompanied by fibroblastic stimulation which proceeds in spite of epithelial regeneration. The exact stimulus for the proliferation and collagen hypersecretion of fibroblasts remains to be determined. The use, in association with corticosteroid treatment, of a structural analogue of L lysine, acexamic acid, to impede collagenesis reveals encouraging perspectives for improved therapy.
