Long-term electroencephalogram monitoring is often used to help distinguish epileptic from dissociative (non-epileptic) seizures. Home video telemetry now offers many of the benefits in diagnosis previously available only with inpatient video telemetry, which is usually regarded as the ‘gold standard’. Here, we describe recent developments in home video telemetry and how we undertake this procedure in our unit.

ObjectivesTo assess the clinical usefulness of HVT over the first 2 years.DesignCohort observational.Subjects60 patients (49 F) with epilepsies or non-epileptic paroxysmal clinical events.Methods48–72 hour continuous video EEG at patients’ own environment.ResultsHVT answered the primary clinical question in 45/60 patients (75%), and provided additional clinical information in 5 patients [2 with unsuspected coexistent psychogenic non-epileptic seizures (PNES) and 3 with unsuspected sleep disorders (SD)]. Of the 12 patients with Idiopathic Generalized Epilepsy, absences had been overestimated in 6 and underestimated in 4, while absence status was recorded in 1 of the 2 patients in whom it had been suspected. Valproate was possible to drastically reduce or stop in 3/6 women. Focal seizures were recorded in 19 of 28 patients with focal epilepsies, PNES were the habitual seizures in further 2 patients, while syndrome classification changed in one. In all 4 patients referred for differentiation between SD and epilepsy, HVT confirmed parasomnias in 2, daytime naps in 1 and idiopathic hypersomnia in 1. The diagnosis of PNES was confirmed in 8 of 13 suspected patients. HVT was unhelpful in the 3 patients referred for not witnessed, poorly understood episodes of loss of consciousness. Three patients switched off the video and 2 failed to change battery on day 2.ConclusionsHVT is a useful diagnostic test provided that diagnostic hypothesis and clinical question are appropriate.

One of the problems solved by analyzing the data of long-term Video EEG monitoring is the differentiation of epileptic and artifact events. For this, not only multichannel EEG signals are used, but also video data analysis, since traditional methods based on the analysis of EEG wavelet spectrograms cannot reliably distinguish an epileptic seizure from a chewing artifact. In this paper, we propose an algorithm for detecting artifact events based on a joint analysis of the level of the optical flow and the ridges of wavelet spectrograms. The preliminary results of the analysis of real clinical data are given. The results show the possibility in principle of reliable distinguishing non-epileptic events from epileptic seizures.

Pregnancy is the most dangerous period in terms of interruption of even persistent and long-term remission. At the same time increasing the dose of anticonvulsant increases the risk of teratogenic effects. Aim. to assess the possibility of using progesterone to prevent relapse of epileptic seizures during pregnancy. Materials and methods. 38 pregnant patients with epilepsy with clinical remission before pregnancy, with relapse of epileptic seizures in I trimester of pregnancy, age 31.81.4 years. Dydrogesterone in a dose of 10 to 60 mg/day was prescribed after the relapse of remission. Anticonvulsant dosage was not changed. The blood progesterone concentration and EEG control was carried out. Results. During pregnancy, the level of progesterone in the blood gradually increased from 77.8 nmol/l at 78 weeks of pregnancy to 521.1 nmol/l at 3637 weeks of pregnancy, without exceeding the limits. EEG results did not deteriorate. None of the patients had seizures during pregnancy. Conclusion. Progesterone therapy is an adequate and safe alternative to increasing the dose of anticonvulsants in case of recurrent seizures during pregnancy.

AbstractDysfunction of the salivary gland and irreversible hyposalivation are the main side effects of radiotherapy treatment for head and neck cancer leading to a drastic decrease of the quality of life of the patients. Approaches aimed at regenerating damaged salivary glands have been proposed as means to provide long-term restoration of tissue function in the affected patients. In studies to elucidate salivary gland regenerative mechanisms, more and more evidence suggests that salivary gland stem/progenitor cell behavior, like many other adult tissues, does not follow that of the hard-wired professional stem cells of the hematopoietic system. In this review, we provide evidence showing that several cell types within the salivary gland epithelium can serve as stem/progenitor-like cells. While these cell populations seem to function mostly as lineage-restricted progenitors during homeostasis, we indicate that upon damage specific plasticity mechanisms might be activated to take part in regeneration of the tissue. In light of these insights, we provide an overview of how recent developments in the adult stem cell research field are changing our thinking of the definition of salivary gland stem cells and their potential plasticity upon damage. These new perspectives may have important implications on the development of new therapeutic approaches to rescue radiation-induced hyposalivation.
