After oral ingestion of 600 ml of refined petrol a 23-year-old male developed multiple organ failure. Acute renal insufficiency due to nephrotoxic tubular necrosis requiring hemodialysis was a major manifestation. Moreover, respiratory failure, seizures, hemolysis, disseminated intravascular coagulation, liver damage and erosions of mucous membranes occurred. The patient subsequently recovered completely. In spite of the poor absorption from the gastrointestinal tract and the high first-pass effect in the liver, massive petrol intoxication may lead to reversible multisystemic lesions.

A patient with metastatic gastric adenocarcinoma had progressive microangiopathic red blood cell changes, thrombocytopenia with increased marrow megakaryocytes, bleeding, altered mentation, and seizure. Coagulation parameters were inconsistent with disseminated intravascular coagulation; a clinical diagnosis of thrombotic thrombocytopenic purpura (TTP) was made. Plasmapheresis resulted in improvement on two separate occasions. The diagnosis of tumor-associated TTP should be considered in cancer patients. Plasmapheresis may be more effective than plasma transfusion alone in this syndrome, perhaps via removal of tumor-induced immune complexes from the circulation. Aggressive management of this complication seems justified in cancer patients for whom effective chemotherapy exists.

During a 4-year period, 26 children with systemic malignancies suffered cerebrovascular accidents. These occurred in 17 patients with lymphoreticular malignancy and nine patients with solid tumors. They were the presenting signs of malignancy in three patients and were the direct cause of death in six. Cerebrovascular accidents were directly related to disseminated intravascular coagulation in eight patients, to chemotherapy in eight patients, to metastatic tumor in three patients, to thrombocytopenia in three patients, and to fungal meningitis in one patient. All patients with disseminated intravascular coagulation had leukemia and at times, cerebrovascular thrombosis predated systemic or laboratory evidence of disseminated intravascular coagulation. This review indicates that four major syndromes are apparent in children with cancer: vascular thrombosis associated with disseminated intravascular coagulation, acute arterial or sagittal sinus thrombosis secondary to L-asparaginase in children with leukemia, acute neurologic dysfunction in patients with osteogenic sarcoma treated with high-dose methotrexate, and obtundation, seizures, and focal neurologic deficits in patients with neuroblastoma metastatic to the torcular region. Although elevated WBC counts and thrombocytopenia occur frequently in children with cancer, in themselves they uncommonly result in strokes. It is concluded that cerebrovascular accidents are a relatively frequent cause of acute neurologic compromise in children with cancer and that certain types of malignancies and their treatment predispose patients to this complication.

Amniotic fluid embolism is a catastrophic event of the intra- and early postpartum period which may also be seen with cesarean delivery and during abortions. Presenting symptomatology includes respiratory distress with cyanosis, shock, and possibly tonic-clonic seizures. DIC frequently occurs. The pathogenesis may include entry of amniotic fluid through lacerations or ruptures of the uterus or cervix, through endocervical veins and through abnormal uteroplacental sites, such as with placental abruption, placenta previa, or placenta accreta. Amniotic fluid probably causes cardiovascular-respiratory symptoms by pulmonary vascular obstruction and through a vasoactive substance causing pulmonary vascular constriction. The lethality of amniotic fluid may be enhanced by a high particulate content or meconium staining. The diagnosis of amniotic fluid embolism may be made ante mortem by demonstrating amniotic fluid debris in central blood samples or expectorated sputum. Postmortem diagnosis often requires meticulous examination of the pulmonary microvasculature with the utilization of special stains. Treatment is directed towards symptoms of shock, arterial hypoxemia, and DIC. Acute renal failure may complicate the picture after shock. If the patient survives the embolic and coagulative problems, recovery is usually complete without long-term sequelae.

Histopathological study on 723 brains from routine necropsies was performed. Ten brains (1.38 percent) were found to have histological lesions of disseminated intravascular coagulation (DIC) with multiple fresh fibrin and/or platelet thrombi in the cerebral microcirculation. Among them, premortem diagnosis was made in only one case, and only two cases also showed evidence of visceral involvement. Microthrombi were found most frequently in the cerebral cortex and hypothalamic region and in the cerebral white matter, brain stem, and cerebellum, in descending order. Neurological symptoms and signs, including lethargy, coma and seizure, were detected in all cases. The abnormal body temperature and/or urinary output observed in most patients appeared to be related to the frequent hypothalamic involvement by DIC. The exclusive or predominant involvement of the brain by multiple microthrombi may be considered as a localized form of DIC. It is probably related to cerebral ischemia since severe acute neuronal ischemic changes also were noted in most brains.

Patients infected with the human immunodeficiency virus (HIV) appear to have a high risk of ischaemic cerebral events. We observed two cases of cerebral infarction in patients with acquired immune deficiency syndrome (AIDS). In the first case, a 38-year-old homosexual with no cardiovascular risk other than smoking presented with rapidly progressive hemiparesia. Brain CT-scan visualized two infarcts in the territory of the right sylvian artery and the arteriography an occlusion of the internal carotid artery. In the second, a 37-year-old homosexual, hospitalization was required for a left-sided pure sensitive epilepsy seizure. There was no cardiovascular risk other than smoking. Magnetic resonance imaging showed parietal ischaemia and thrombus in the left atrium without atrial hypertrophy was seen at transoesophageal echocardiography. In both cases, there was no evidence of endocarditis, dissection of the neck vessels or disseminated intravascular coagulation nor of associated viral or bacterial infectious complication of AIDS. Angiographic findings eliminated cerebral vascularitis. Among the perturbed haemostasis factors previously reported in HIV+ patients, we observed free proteins S deficiency (68 and 43%) and heparin cofactor II deficiency (54 and 40%). Serum albumin was 33 and 32 g/l respectively. Outcome was favourable in both cases with anticoagulant therapy. These coagulation anomalies would not appear sufficient to explain cerebral infarction. Other mechanisms including immune complexed deposition, direct HIV toxicity for endothelial cells or the effect of cytokines on smooth muscles fibres and fibroblasts are probably more important causal factors.

Sixty cases of severe eclampsia were treated in an intensive care unit between January 1989 and September 1993. Mean age was 26, and 70% of patients were primipara. The pregnancy has been unsupervised in almost all cases. All had visceral lesions and/or hematologic problems and there was impaired conscious level in 9 cases out of 10. Medical treatment involved the control of seizures and of hypertension. Cesarean section was performed in 34 cases. The maternal death rate was 23.3%. Our experience indicates that mortality depends upon visceral lesions (cerebral, disseminated intravascular coagulation, acute pulmonary edema, Hellp syndrome). Better awareness of severity factors in preeclampsia improves both maternal and fetal prognosis by precisely indicating the best time for fetal extraction.

Nine children with perinatal occlusion of the middle cerebral artery, resulting in unilateral enlargement of one lateral cerebral ventricle associated with cortical atrophy and subcortical cavity formation, were operated on because of intractable epilepsy. All subjects exhibited mild to severe hemiparesis, localized in the right side of the body in six instances and in the left side in the three cases. All but one patient presented with some degree of psychomotor retardation. The surgical treatment consisted of the removal of the atrophic cerebral cortex. One child died after surgery because of disseminated intravascular coagulation. All the remaining eight children benefited from the operation, with a decrease in the hypertonia of the affected limbs and an improvement in dexterity and gait as well as in intellectual performance. Five patients could be considered seizure-free following the surgical treatment, and the remaining three experienced a significant reduction in the frequency of the seizures.

We reported a case of acute pancreatitis occurring during administration of valproic acid for epilepsy. About four years prior to the first onset of acute pancreatitis, treatment with valproic acid for his seizures was started. The first pancreatitis improved by conservative therapy within a week. He continued valproic acid after the first episode. Two months later, the second acute pancreatitis occurred. The second episode was complicated with disseminated intravascular coagulation, but responded to conservative therapy. After the second episode, the valproic acid was discontinued and pancreatitis has not recurred. Pancreatitis associated with valproic acid may be severe, and therefore valproic acid should be used with caution.

The rural CGW population has not yet undergone the metamorphosis experienced by its urban counterparts. Reminiscent of a past era, suicides far outweight homicides. Although many rural firearm injuries involve hunting accidents, these comprise only a small fraction of CGW at best. Similarly, although many rural firearm injuries involve shotguns or rifles, few CGW result from these weapons. Although the number of patients is small, those with shotgun or rifle injuries manifest lower mortality rates. The authors have confirmed the notion that caliber of civilian weapons is difficult to correlate with outcome. The geographic size of the rural catchment area is an important consideration because it must select a population able to withstand transfer. The authors noted an inverse relationship between length of time before arrival at the facility and mortality. The selection phenomenon probably accounts for the reduced mortality found in the authors series versus most others. Prognostic features of individual gunshot wounds are likely to be similar among varied populations when circumstances of the injury are matched. Thus, one expects similar features on initial examination and CT scan to have similar predictive value. The authors confirmed that CGS and specific deficits were strong predictors of outcome. No patient with a GCS score of 5 or less on admission survived. Absent pupillary response, absent brain stem function, presence of respiratory drive or cough only, and posturing were strong indicators of impending death. The authors confirmed the prognostic value associated with CT evidence of intraventricular hemorrhage, transventricular trajectory, transtentorial herniation, massive edema, and bihemispheric injury. Interestingly, presence of extensive facial fractures, an indicator of trajectory, suggested better outcome. Subarachnoid hemorrhage did not reach prognostic significance. Roughly half of the authors' patients had positive serum ethanol levels, although the test was unable to discern prognosis. Abnormality of any coagulation parameter and frank disseminated intravascular coagulation were correlated with poor outcome. Likewise, thrombocytopenia occurring within the first 24 hours was an indicator of poor prognosis. Although prophylactic antibiotics were not used in all cases, the authors encountered no deep or superficial infections in surviving patients. The prevalence of seizures in the authors' series despite prophylactic AED is unusually high. This feature merits further study.
