Seizures after epilepsy surgery.

This article reviews types and prognostic significance of seizures that occur after epilepsy surgery, so-called postsurgical seizures.

[Paraproteins and lymphoma in HIV positive patients]. / Paraproteine und Lymphome bei HIV-positiven Patienten.

BACKGROUND AND AIM: Compared to healthy subjects there is a higher incidence of monoclonal immunoglobulins (= paraproteins = PP) in patients infected with the human immunodeficiency virus (HIV). High-grade B-cell non-Hodgkin's lymphomas (NHL) are the second most common neoplasms in these patients. Our aim was to determine whether paraproteins would be of diagnostic significance regarding an underlying or developing NHL. PATIENTS AND METHODS: The sera of 202 HIV-positive patients were tested for the presence of monoclonal or oligoclonal bands by using high-resolution-electrophoresis (HRE) and immunofixation (IFX). We also examined immunoglobulin concentrations, leucocyte count, lymphocyte count, CD4 lymphocyte count and CD4/CD8-ratio and collected clinical data. RESULTS: Paraproteins were detected in 26 (12.8%) of the patients. 84.6% of PP were IgG, in 80.7% associated with a kappa light chain. Patients with monoclonal or oligoclonal bands developed NHL significantly more often compared to those without PP (16.7% and 2.8%, respectively (p < 0.05%)). The CD4 count was significantly higher in patients with PP. There was no difference in levels of immunoglobulins, leucocyte count, lymphocyte count and CD4/CD8-ratio. The prevalence of PP was equally distributed in patients at different CDC-stages of HIV-infection. Common acute systemic infections like pneumocystis carinii pneumonia (PCP), toxoplasmosis, mycobacteriosis or cytomegalovirus (CMV) infection were not associated with paraproteins. CONCLUSION: We conclude that paraproteins could indicate the presence of a non-Hodgkin's-lymphoma.

[Polyneuropathies in monoclonal gammopathy of undetermined significance: initial manifestation of a lymphoma]. / Schwerpunktpolyneuropathie bei monoklonaler Gammopathie unbestimmter Signifikanz (MGUS): Erstmanifestation eines Lymphoms.

BACKGROUND: Monoclonal gammopathies-including so-called monoclonal gammopathies of undetermined significance-MGUS-may cause polyneuropathies, even if immunoglobulin concentrations are within a normal range. CASE REPORT: We report on a patient with a rapidly progressive polyneuropathy with severe motor disturbances in whom a small amount of a monoclonal IgM kappa cryoglobulin was found. Only by extensive, repeatedly performed diagnostic procedures could scattered lymphoma cells be detected. Nonspecific immunosuppression had been unsuccessful but eventually a more specific chemotherapy led to an almost complete, sustained recovery. CONCLUSION: This case shows that in patients with a polyneuropathy of uncertain etiology monoclonal immunoglobulins should be looked for and that a MGUS can precede a lymphoma. Therefore these, patients with a MGUS and clinical deterioration despite conventional immunosuppressive treatment should undergo large-scale diagnostic check-up to make sure that the chance for an adequate chemotherapy is taken.

[Suggestion for a new, patient-oriented epilepsy classification]. / Vorschlag für eine neue patientenorientierte Epilepsieklassifikation.

The recent proposal by the ILAE Task Force for Epilepsy Classification is a multiaxial, syndrome-oriented approach. Epilepsy syndromes--at least as defined by the ILAE Task Force--group patients according to multiple, usually poorly defined parameters. As a result, these syndromes frequently show significant overlap and may change with patient age. We propose a five-dimensional and patient-oriented approach to epilepsy classification. This approach shifts away from syndrome orientation, using independent criteria in each of the five dimensions similarly to the diagnostic process in general neurology. The main dimensions of this new classification consist of (1) localizing the epileptogenic zone, (2) semiology of the seizure, (3) etiology, (4) seizure frequency, and (5) related medical conditions. These dimensions characterize all information necessary for patient management, are independent parameters, and include information more pertinent than the ILAE axes with regard to patient management. All cases can be classified according to this five-dimensional system, even at initial encounter when no detailed test results are available. Information from clinical tests such as MRI and EEG are translated into the best possible working hypothesis at the time of classification, allowing increased precision of the classification as additional information becomes available.
