Delayed effects of a migrated foreign body (sewing needle) in the cervical spine: a case report.

STUDY DESIGN: A case report is presented. OBJECTIVE: This report documents one case of intraspinal migration of a metal foreign body. SUMMARY OF BACKGROUND DATA: The migration and penetration of foreign bodies into the spine have been described, but there are only three reports of a needle as the causative object. METHODS: This case report included a chart review, an examination of the patient, and a literature search. RESULTS: The patient successfully underwent surgery, in which the foreign body (a sewing needle) was removed. CONCLUSION: It is important to be aware of the possible delayed penetration of a foreign body into the spine even in patients with few or no symptoms.

Reversible posterior leucoencephalopathy syndrome in systemic lupus and vasculitis.

OBJECTIVES: Reversible posterior leucoencephalopathy syndrome (RPLS) may develop in patients with renal insufficiency, hypertension, and immunosuppression, and is managed by prompt antihypertensive and anticonvulsant treatment. Four patients with renal insufficiency and fluid overload associated with Wegener's granulomatosis (one patient) and systemic lupus erythematosus (SLE) (three patients) are described, whose clinical picture and neuroimaging indicated RPLS. CASE REPORTS: All patients had headache, seizures, visual abnormalities, and transient motor deficit, and were hypertensive at the onset of the symptoms. Head computed tomography (CT) scan and magnetic resonance imaging showed predominantly posterior signal abnormalities, which were more conspicuous on T(2) weighted spin echo images than on CT scan. All patients had some form of cytotoxic treatment shortly before the syndrome developed, and dramatically responded to blood pressure control and anticonvulsant treatment. In two patients with SLE, dialysis was required for renal insufficiency. DISCUSSION: Follow up neuroimaging studies showed almost complete resolution of signal abnormalities, and suggested that RPLS was associated with cerebral oedema without concomitant infarction. The treatment of hypertension and neurotoxic condition such as uraemia appears of primary importance, while immunosuppressive treatment may cause further damage of the blood-brain barrier.

Subacute measles encephalitis in a young man immunosuppressed for ankylosing spondylitis.

Subacute measles encephalitis occurred 1 month after measles onset in a 26-year-old HIV-negative man undergoing immunosuppressive treatment for ankylosing spondylitis. He had seizures, a decline in mental status, and progressive impairment of consciousness, with a fatal outcome. Despite severely deficient cellular immunity, the elevated antimeasles antibody titers and CSF findings indicated that humoral immunity was not impaired. Histologic, electron microscopic, and immunocytochemical studies revealed the typical intranuclear inclusions of paramyxovirus nucleocapsids, and measles virus antigen in neurons and oligodendrocytes.

De novo status epilepticus as the presenting sign of neurosyphilis.

Although the incidence of seizures in neurosyphilis ranges from 14 to 60%, status epilepticus (SE) as a presenting complaint of neurosyphilis is definitely rare. A 44-year-old human immunodeficiency virus (HIV)-negative man with no history of epilepsy suddenly presented with acute mental confusion and was diagnosed as having a de novo complex partial nonconvulsive SE. Cerebrospinal fluid (CSF) findings, neuroimaging, and clinical course indicated that SE was the presenting symptom of an undiagnosed syphilitic meningovasculitis. The case is presented with a review of previous reports to emphasize the differential features and to underscore the importance of considering neurosyphilis among the possible causes of de novo SE.

Long-term observations on the clinical use of lamotrigine as add-on drug in patients with epilepsy.

We report open-label clinical observations of additional lamotrigine (LTG) in 16 adult patients with refractory epilepsy, aimed to assess the long-term efficacy and safety of LTG in clinical use. LTG was added to the current antiepileptic drug (AED) regimen at a daily dosage of 200-400 mg depending on the concomitant treatment. Ten patients completed one year's treatment and were followed up to an overall exposure ranging 15-38 months. Six patients (38% of the initial group) had a reduction of seizure frequency greater than 50% of pre-treatment baseline after one year; the further follow-up indicated some efficacy decline, since the percentage of improved patients dropped to 19% after 2 years and 13% after 3 years. The dropouts during the first year were due to seizure breakthrough (two patients), Steven-Johnson-like syndrome (one patient) and reasons unrelated to treatment (three patients); in one patient LTG treatment was stopped due to macrocytic anemia after 23 months. Other reported adverse events were dizziness, mild ataxia, diplopia and localized purpura. No other hematological or biochemical changes were noted. LTG was not associated with any significant changes in plasma concentrations of concomitant AEDs. These findings confirm the moderate efficacy and low toxicity of long-term LTG in severe epilepsy.

GABA and phosphatidylserine in human photosensitivity: a pilot study.

Previous experimental studies have shown that the simultaneous administration of gamma-aminobutyric acid (GABA) and phosphatidylserine (PS) can exert an anticonvulsant activity in different seizure models; moreover, a preliminary trial showed some effect of the association GABA-PS in patients with absence seizures. The aim of this study was to investigate the antiepileptic properties of GABA-PS in the model of human photosensitivity. Nine patients with epilepsy associated with an EEG pattern of photoconvulsive response at intermittent photic stimulation entered a 3-day study. The photosensitivity range (PSR) was determined at hourly intervals both in basal conditions and after the administration of a single oral dose of GABA (3000 mg) and PS (600 or 1200 mg). The administration of GABA-PS was not associated with any systematic changes of PSR, nor with any significant differences of time course profiles on each daily session. No correlation was found between PSR percent deviations from baseline and GABA serum levels. These results indicate that a single acute administration of GABA-PS has no effect in the human photosensitivity model, and suggest that the efficacy of GABA-PS in human epilepsy, as shown by a preliminary investigation, may possibly require chronic administration.

Epileptic seizures in patients with acute catatonic syndrome.

Acute catatonic syndrome is a condition that can be caused by a variety of metabolic, neurological, psychiatric, and toxic conditions, including neuroleptic malignant syndrome. Although ictal catatonia as a manifestation of non-convulsive status epilepticus has been described, reference to the occurrence of seizures in patients with acute catatonic syndrome is anecdotal. Twenty nine patients with acute catatonic syndrome were reviewed to identify patients with seizures after the onset of acute catatonic syndrome. Patients were divided into four diagnostic groups: affective (15), schizophrenic (eight), toxic (two), and organic (four). Seizures occurred in four patients (13.8%): two patients with dystonic seizures had viral encephalitis and schizophrenic disorder respectively; one patient with complex partial seizures had viral encephalitis and one patient with absence status had neuroleptic malignant syndrome. The results indicate the value of EEG in detection of epileptic activity in patients with acute catatonic syndrome, both at onset and in the course of such disturbance, particularly to provide a differential diagnosis between pseudo-seizures and neuroleptic-induced acute dystonia.
