11 cases of cerebral venous thrombosis in adults are reported. Main clinical signs are: intracranial hypertension (headache, nausea, papilledema in 7 cases, loss of consciousness in 6 cases, neurological deficit in 6 cases, seizure in 4 cases. 1 patient is dead, who did not receive heparin treatment. Delay before diagnosis is between 2 and 20 days, and is shortened when arteriography or MRI are available and prescribed. At least one (or several) CT examination was performed in 10 patients. Direct signs of thrombosis are uneasily detected without contrast injection, seen here in 4 cases. Empty delta sign is observed in 7 patients, lately in 4 cases, and once only afterwards. Cerebral infarction is visualized in 7 cases over 10. Its features frequently seem evocative for cerebral venous thrombosis: triangularin 4 cases or nodular shape in 3 cases with hemorragic infarct in 7 cases, with bilateral topography in 6 cases, in frontal or central areas in 7 cases. 6 patients had a MRI examination. All cerebral infarctions appeared haemorragical, even at early stages. During subacute period, venous thrombosis is constantly and easily detected by the mean of methemoglobin high signal intensity on T1 weighted images. The prediagnosis delay is short, without necessity of arteriography. MRI should take the place of CT and arteriography in investigation of a clinically suspected cerebral venous thrombosis.

A case of systemic lupus erythematosus (SLE) with benign intracranial hypertension (BIH) is reported. A 41-year-old male with a history of SLE starting in 1982 was admitted to our hospital in December 1989 because of headache and vertigo. Laboratory examinations on admission showed proteinuria, mild anemia, and positive antinuclear and anti-Sm antibodies. No abnormal findings except high pressure of 350 mmH2O were observed in his cerebrospinal fluid (CSF). Fundoscopic examinations showed marked bilateral papilledema and retinal bleeding. Brain CT, MRI and angiography revealed diffuse brain edema without space occupying lesion and cerebrovascular diseases. Because there were no diseases such as endocrinological disorders, severe anemia, and no history of the administration of drugs which might cause intracranial hypertension, the diagnosis of BIH was made. Subsequently, he was treated with intravenous methylprednisolone therapy and osmotic diuretics and his clinical symptoms and pressure of CSF gradually improved. The decrease of CSF adsorption was observed with RI cisternography in our case. Psychosis, seizures and meningitis are common CNS manifestations in SLE patients. But BIH is very rare and its cause is unclear. Only 17 cases of SLE with BIH have been reported. The pathogenesis and treatment of BIH in SLE patients were discussed in this paper.

Hypertensive encephalopathy is a syndrome consisting of headache, seizures, visual changes, and other neurologic disturbances in patients with elevated systemic blood pressure. The purpose of this study was to analyze the imaging findings in 14 patients with hypertensive encephalopathy. CT (n = 13), MR (n = 12), and single-photon emission computed tomography (n = 2) examinations performed in these patients before and after resolution of symptoms were reviewed. Eight had the preeclampsia-eclampsia syndrome, and six had hypertensive encephalopathy due to other causes. CT and MR findings in all patients having these examinations were indicative of edema in the cortex and subcortical white matter in the occipital lobes. Two of the 14 patients also had similar findings in the cerebellum and frontal lobes. Single-photon emission computed tomography showed increased vascular perfusion adjacent to areas that appeared abnormal on CT and MR. The findings on the imaging studies resolved on follow-up examinations performed after the hypertension was corrected. Our results suggest that the radiologic findings associated with hypertensive encephalopathy may be useful in establishing the diagnosis in the appropriate clinical setting.

The authors studied the efficacy of cavinton as an agent helpful in preventing neurologic disorders in the newborn with hypoxic ischemic encephalopathy due to intracranial birth trauma. The short-term results of the treatment were elucidated in 61 children. In group I including 20 persons given conventional therapy, the disappearance of seizures was recorded in 6 patients; out of 41 children (group II) given additionally cavinton, in 27. Twenty-nine children were followed up for a year. In group I, convulsive paroxysms recurred in 4 patients, whereas in the group II children, no convulsive syndrome was recorded on the follow-up. The group II children also showed a decrease of the phenomena of intracranial hypertension and normalization of the psychomotor development. The preventive effect of cavinton seen in children with a history of birth trauma may be accounted for by its capacity of normalizing cerebrovascular disorders and by its own anticonvulsive properties.

Three cases of pleomorphic xanthoastrocytomas (P.X.A.), a low grade leptomeningeal glioma are reported. Prominent histological features used for diagnosis were a cellular pleomorphism of G.F.A.P. positive cells, with intracytoplasmic lipidic vacuols. A reticulinic network and mononuclear cells infiltrates have been observed. A weak mitotic activity and lack of necrosis and of endothelial cells proliferation were significant additional features necessary for diagnosis. Our cases were observed during the surgical management of young patients with resistant epilepsy. Neuroradiological examinations showed a tumor superficially located within the temporal or the parietal lobe. This tumor could be calcified and/or cystic. Operative aspects showed a firm and non-encapsulated leptomeningeal tumor with possible various colors. Our patients were seizures-free after surgery even during the follow-up. From the currently reported cases clinical follow-up ranging for 1.5 to 3 years is not sufficient to predict a favorable carcinologic prognosis. P.X.A. is an uncommon tumor and less than 50 cases are reported throughout the literature. This tumor affecting young subjects mainly during the second decade is revealed in the majority of cases (3/4) by epileptic seizures, less frequently by a deficit or by an intracranial hypertension. The great majority of clinical events are observed before 20 years. The functional prognosis is rather good after surgery with a disappearance of epileptic fits in about 50% of the cases. Throughout the literature the prognosis of this tumor seems to be comparable to low-grade astrocytomas. Optimal management of P.X.A. seems to be primary surgical resection with later surgery for residual or recurrent tumor. The role of radiotherapy in the management of P.X.A. is at this time uncertain.

Dopamine beta-hydroxylase (DBH) deficiency is a genetic disorder in which affected patients cannot synthesize norepinephrine, epinephrine, and octopamine in either the central nervous system or the peripheral autonomic neurons. Dopamine acts as a false neurotransmitter in their noradrenergic neurons. Neonates with DBH deficiency have had episodic hypothermia, hypoglycemia, and hypotension, but survivors sometimes cope relatively well until late childhood when overwhelming orthostatic hypotension profoundly limits their activities. The hypotension may be so severe that clonic seizures supervene. Most currently recognized patients are young or middle-aged adults. The diagnosis is established by the observation of severe orthostatic hypotension in a patient whose plasma norepinephrine/dopamine ratio is much less than one.

Therapeutic stimulation of the autonomic nervous system has been limited by lack of qualitative or quantitative evaluation of autonomic mechanisms. This article provides an historical review of knowledge about autonomic pathways and critical evaluation of available tests of autonomic function. Recent developments in evaluation of autonomic dysfunction and improvement in techniques of neurostimulation have facilitated the development of a number of clinically useful treatments for bladder control, sexual problems, peripheral vascular disease, angina pectoris, and seizure disorders. Future therapeutic measures may allow specific control of hypertension, pain, cardiac arrhythmias, trophic disorders and balance.

The toxic effects of cocaine are becoming more widely recognized as the popularity of the drug increases. Although overdose is usually fatal, treatment is available for users who experience agitation, seizure, arrhythmias, severe hypertension, or other side effects. Hospital admission is often necessary to allow monitoring of the acute situation. Initial management involves standard life-support measures. Therapeutic agents are given, as appropriate, both to control acute reactions and to counteract continuing toxicity.

Besides general complications of immunosuppression such as increased susceptibility to opportunistic infections or malignancy, individual immunosuppressive agents are associated with specific side effects. Nephrotoxicity is the major side effect of cyclosporine (CsA). Various attempts have been made to minimize this toxicity, such as monitoring drug blood levels, modifying the protocol, and coadministering other agents. Other side effects caused by CsA are hepatotoxicity, hyperkalemia, hypertension, tremor, gum overgrowth, and hirsutism. Azathioprine (AZA) causes dose-related bone marrow suppression, commonly leading to leukopenia. Careful monitoring of complete blood cell count and dosage adjustment according to white blood cell count are usually adequate to prevent serious leukopenia. The side effects of corticosteroids are numerous and include slow wound healing and de novo insulin-dependent diabetes mellitus. Many complications are dose related, and with low dosage or discontinuation of steroids, their frequency rapidly decreases. Antilymphoblast and antithymocyte globulins (P-ALG) are foreign antibodies and may cause allergic-type reactions such as fever, chill, and hypotension. The initial side effect of monoclonal antibody (muromonab-CD3, OKT3) is similar to that of P-ALG. It includes high fever, shaking chills, headache, rigors, and hypotension. To prevent it, acetaminophen, an antihistamine, and a steroid usually are administered before injection. Because this agent is also associated with high frequency of pulmonary edema, it should not be given to any patient who has more than 3% body weight gain during the week prior to therapy. In rare case, it causes aseptic meningitis or encephalopathy, which is manifested by fever, severe headache, and seizure.

Pregnancy-induced hypertension is a disorder of unknown etiology unique to pregnant women. Classic clinical manifestations include hypertension, proteinuria, and edema. Early recognition and proper management of this disease may serve to avoid serious maternal complications. Ultimate maternal treatment depends on delivery of the fetus and placenta. Advanced stages of this disease result in multi-organ system dysfunction that may be life-threatening to the mother and her fetus. Such maternal complications of PIH include severe hypertension, oliguria or anuria, HELLP syndrome, eclamptic seizures, liver rupture, pulmonary edema, cerebral edema, and abruptio placentae. A multidisciplinary approach of the critical care team often will effect a reduction in maternal morbidity and mortality.
