However, sensory conduction velocity (SCV) in sural nerve distinctly separated types I and II of HMSN (8). As in most of our patients with HMSN sural nerve was unexcitable, we introduced SCV estimation in the distal segments of median and ulnar nerves. So, we studied 124 patients from families with typical and uncomplicated cases of Charcot-Marie-Tooth disease (CMTD): 68 patients had the \"hypertrophic\" form (type I) and 56 cases the \"neuronal\" form (type II). In this series, 16 patients had median MCV from 35 to 45 m/s, but SCV in the median and ulnar nerves separated 7 cases with type I and 9 patients with type II of HMSN. In conclusion, the type I and II of HMSN were delimited in most of the studied cases by MCV values in the median nerve. Nevertheless, in cases difficult to be classified either into type I or II of HMSN, i.e. patients with MCV from 35 to 45 m/s, only SCV measurements in distal median and ulnar nerves segments can distinctly separate type I (a slowing over 40% from control values), indicating that this type is underlain by a process of segmental demyelination (SD), which also was confirmed by sural nerve biopsy data. In our cases with HMSN type II MCV was either normal or slightly slowed. By contrast SCV was significantly slowed (a slowing of up to 30%). In addition, we have also a few cases of complicated HMSN forms (rare variants), associated with: 1. Isaacs' syndrome; 2. \"denervation-reinnervation\" muscle hypertrophy; and 3. Marinesco-Sjögren syndrome. 1. In 3 patients, the clinical features of \"neuronal\" form of CMTD were associated with fasciculation, cramps, impaired muscular relaxation, and percussion myotonia with respective electromyographic (EMG) accompaniments, which were responsive to valproic acid therapy. 2. On the other hand 3 patients developed in addition to the Isaacs' syndrome a significant \"denervation-reinnervation\" muscle hypertrophy, confirmed by both morphometric data on muscle biopsy and computed tomography. In these patients there was an increased proportion of type I and a decreased one either of type IIB or of type IIA fibres, without myotonic or dystrophic features.(ABSTRACT TRUNCATED AT 400 WORDS)</p>","PeriodicalId":77370,"journal":{"name":"Romanian journal of neurology and psychiatry = Revue roumaine de neurologie et psychiatrie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19007388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The administration of ethosuximide has a twofold effect resulting in a diminished spindling activity of the reticular thalamic nucleus as well as a decrease in the incidence of epileptic spike-and-wave discharges.

The study showed a significant interictal hyperresponsivity in epileptics with TRPS vs. the normal subjects of control group I, which consisted in a marked increase of the intensity of the orienting reaction components. This hyperresponsivity was also more marked than that noted in epileptics with therapy-controlled partial seizures of control group II. The correlational analysis of data showed that the severity of these responsiveness disturbances in epileptics with TRPS depended on the patients' age, type of electroclinical seizures, pretrial seizure frequency, type of resting EEG, administered treatment (no. of administered antiepileptic drugs/patient), daily dose, as well as on the serum level of these drugs. The multivariate regression analysis showed that the most significant predictive variables for the responsiveness disturbances were the pretrial seizure frequency, type of electroclinical seizures, daily dose of administered antiepileptic drugs and their serum level. The data also evidenced that the antiepileptic treatment improves the interictal responsiveness disturbances, the effect being the more marked as the treatment was more sustained.
