It is suggested that patients with the haemolytic-uraemic syndrome and related disorders (such as thrombotic thrombocytopenic purpura) lack a plasma factor which stimulates prostacyclin (P.G.I2) activity. Normal plasma would supply the missing factor and is a rational treatment for some life-threatening symptoms (thrombocytopenia, haemolytic anaemia, hypertension) of this syndrome.

Two employees in a mercuric oxide manufacturing plant developed neurologic changes not previously reported from the exposure to inorganic mercury or elemental mercury vapor. The symptoms, physical findings and laboratory studies resembled those found in amyotrophic lateral sclerosis (ALS) and organic mercury intoxication. Nineteen employees are reported who precipitously developed ...

Phenytoin sodium intoxication of subacute onset may occur in cases of nonepileptic patients who receive phenytoin for suppression of cardiac arrhythmias. The case reported here is of a syndrome that consisted of dementia, cerebellar dysfunction, and peripheral neuropathy. Withdrawal of phenytoin was followed by a slow improvement in the syndrome. ...

Three family members intoxicated with methyl bromide presented with a variety of neuropsychiatric manifestations including coma, severe status epilepticus, hyporeflexia, and acute psychosis. The simulation of Reye syndrome in the child emphasizes the need for careful toxicologic screening of all children presenting with this syndrome. The initial diagnostic difficulty encountered ...

The authors warn physicians that intoxication by Angel's Trumpet (Datura sauveolens) is becoming more frequent due to its use by adolescents and young adults as a legal, readily available hallucinogen. Ingestion of Angel's Trumpet flowers or a tea brewed from them results in an alkaloid-induced central nervous system anticholinergic syndrome ...

In a young woman a twin pregnancy and uneventful labour were complicated by the development of the postpartum haemolytic-uraemic syndrome. A number of unusual features of this syndrome were present, including early onset, accompanying hepatocellular necrosis, hepatic encephalopathy and bleeding diathesis. Early institution of heparin therapy combined with coagulation factor ...

Two children are described with frequent relapsing haemolytic uraemic syndrome. In the first child, the disease reoccurred twice and in the second three times. In both, relapses could be related to a viral infection, as well as to a preceding inoculation for diphtheria--pertussis--tetanus--poliomyelitis in the second patient. Recurrent haemolytic-uraemic syndrome ...

A new syndrome, paradoxical intoxication, has been defined in which high levels of hydantoins, and in one instance carbamazepine, produced an increase in seizures with little or no evidence of intoxication; a decrease in these levels produced an improvement in seizure control. This syndrome occurs often but not exclusively in ...

The treatment of five children with the haemolytic-uraemic syndrome using streptokinase is described to illustrate the difficulties and limitations of thrombolytic therapy in this disease. This experience is germane to the design of multicentre clinical trials.A multivariate analysis relating clinical outcome to the data obtained at the time of admission ...

Among 48 patients with a typhoid infection 6 (12.5%) developed the haemolytic-uraemic syndrome. Neither glucose-6-phosphate dehydrogenase deficiency nor therapy with chloramphenicol could be incriminated as the causal factor. Evidence presented here suggests that the mechanism is localized intravascular coagulation.The presence of leucocytosis in typhoid fever suggests a complication and should ...

Three children with the haemolytic-uraemic syndrome were treated with intravenous heparin. Peritoneal dialysis was required for two of them, one of whom died after 26 days of therapy. Renal biopsy specimens from the two survivors showed widespread glomerular disease, which appeared permanent in one case, but only occasional thrombi. It ...

In a calf nutrition-metabolism study in which a high glucose (60% glucose and 3% lard) versus a high fat (23% glucose and 30% lard) milk replacer were compared, a syndrome characterized by anorexia, an unstable gait, depression, a distended abdomen and an odor of alcohol on the breath was observed ...

After a brief discussion of the biologic effects of ionizing radiation, the author examines the pathology and clinical features of the Acute Radiation Syndrome, comprised of central nervous system, gastrointestinal, and hematopoietic phases. The currently accepted modes of treatment are included in this discussion. There is also a section on ...

Classification of radiation injury on a clinical basis is useful for determining priorities of evacuation and treatment in a mass casualty situation. Victims of nuclear attack would probably also suffer traumatic and thermal injuries. Four categories of surgical injury have therefore been combined with three categories of radiation injury to ...

The dry leucocytic mass can be recommended for use in combination with other therapeutic preparations (Vitamin B12, steroid hormones) in the treatment of patients suffering from agranulocy tosis. In leukopenia of radiation etiology, especially when the dry leucocytic mass had been employed simultaneously with radiation therapy in the prevention of ...

Spinal transection of one of a parabiotic pair of rats is immediately followed by a state indistinguishable in visual and hematologic characteristics from spontaneous "parabiosis intoxication." The transected rat develops erythremia, hyperhemoglobinemia, and an increased hematocrit count; whereas the twin concurrently shows anemia characterized by a decrease in hemoglobin, erythrocyte ...
