paraquat poisoning: significance of plasma-paraquat concentrations.plasma-paraquat concentrations were measured in 79 patients who had ingested liquid or granular weedkillers containing paraquat. at any given time after ingestion, the plasma-paraquat concentrations in the patients who died usually exceeded those in the survivors. it is suggested that measurement of plasma-paraquat concentrations is useful in assessing the severity and predicting the outcome of poisoning. patients whose plasma concentrations do not exceed 2.0, 0.6, 0.3, 0.16, and 0.1 mg/l at 4, ...199989392
successive generations of child maltreatment. the children.families were identified, in north-east wiltshire (uk), (population 200,000), in which there was a pattern of two or more generations of child maltreatment and where there were also two or more children maltreated in the current generation (born between 1960 and 1980). these children had high rates of mental handicap, backwardness, and antisocial behaviour, and there were also characteristic patterns of emotional disturbance. the post-neonatal death rate for the 294 index children was very high, ...19993250697
[esophago-jejunostomy at the level of the neck for restoration of continuity in carcinoma of the esophagus (after esophageal resection or for palliative reasons) (author's transl)].a technic of esophago-jejunostomy in the neck is described which uses a y loop, to which is given a further blood supply through the internal mammary vessels, united to the vessels of the transplanted loop through microsurgical anastomoses. this technic is used either for purely palliative reasons or when the esophageal tumour has become inoperable, or after esophagectomy as a procedure for reconstruction of the digestive tract.199989117
urinary diversion for ureteral obstruction in the presence of recurrent colon carcinoma.selection of patients who might benefit from urinary diversion when recurrent colorectal cancer obstructs both ureters is difficult. combinations of chemotherapy and radiation therapy will prolong a useful, comfortable and dignified life in some patients. radiation therapy seems to be more effective than chemotherapy and, therefore, patients most likely to benefit are those with localized pelvic recurrences without carcinomatosis and those who are well nourished, active and highly motivated. her ...199989205
[obstacles to university studies: the point of view of quebec nurses].this research project aimed at identifying obstacles that prevent nurses from taking university courses. through a random stratified sampling method, we selected 2,063 persons among the 22,494 french speaking nurses of quebec who worked as nurses and did not take any courses beyond their professional training at the cegep level or at the hospital. a 50 statement questionnaire was mailed out and 1,197 questionnaires were returned and reviewed. the ten most important statements were considered und ...19993250721
thyrotoxicosis during pregnancy.the diagnosis of thyrotoxicosis during pregnancy is difficult on clinical grounds only. the determination of free thyroid hormones or free thyroid hormone indices is important and is possibly supplemented by the trh stimulation test. thyrotoxicosis during pregnancy should always be treated actively. the authors recommend subtotal thyroidectomy if there are indications for surgical therapy (nodular goitre or large diffuse goitre). otherwise treatment with thyrostatic agents is used. after operati ...199984547
factors affecting the fibrinolytic response to surgery.the stress of injury and surgical operation results in an initial increase in the spontaneous fibrinolytic activity of the blood which is followed by a period of reduced activity in the postinjury or postoperative period. this 'fibrinolytic shutdown' is particularly marked in patients with malignant disease and occurs irrespective of whether or not they develop a deep venous thrombosis. it also occurs in patients with benign disease and in these patients is greater, though only on the first post ...199984546
biogenic amines derived from tryptophan in systemic and cutaneous scleroderma.blood levels of serotonin (5-ht) and urinary excretion of 5-hydroxyindole-acetic acid (5-hiaa), tryptamine (t), and indole-acetic acid (iaa) were determined in 39 cases of systemic scleroderma and in 7 cases of very severe cutaneous scleroderma. the t/iaa ratio was normal and serotonin elevated in mild and rather severe acrosclerosis alike, i.e. in systemic scleroderma with pronounced vascular involvement. the t/iaa ratio was increased and serotonin normal in severe acroscleroderma, representing ...199984460
