[Autoimmune diseases are of multifactorial origin. Due to the disturbed immune tolerance, autoreactive T and B cells target self antigens, which lead to permanent organ damages. Despite of the recently introduced therapeutic protocols, the disease has a chronic course, in many cases with lethal outcome. The efficacy of stem cell therapy has been observed in animal models of autoimmune diseases and in autoimmune diseases associated with haematological disorders. Although this approach has been applied for more than 30 years, its widespread use has been delayed by the serious side effects caused by the conditioning treatments based on oncological protocols. The evaluation of the data of patients who had undergone autologous stem cell therapy revealed that the use of protocols for conditioning treatments that mostly cause lymphoablation, and also, if the procedures are carried out in specialized centres significantly reduce mortality, while the therapeutic efficacy remains optimal. Indications for autologous CD34+ stem cell therapy in patients with autoimmune diseases are internationally established and accepted. New, multicentric investigations have been launched in order to compare the efficacy of various protocols.]

[INTRODUCTION - Synchronous colorectal cancers are not uncommon, therefore, total colonoscopy is indicated even in cases of distally located large bowel carcinomas. CASE REPORT - An 84-year-old man had emergency surgery because of bowel obstruction and a node-negative carcinoma of the sigmoid colon was removed according to Hartmann. Before the reconstruction of bowel continuity, colonoscopy revealed a relatively small polypoid tumour in the right colon, unsuitable for colonoscopic polypectomy. Two localization clips were then inserted at the site of the endoscopic biopsy that later resulted in the diagnosis of adenocarcinoma. At the time of the reconstruction surgery, an appendectomy was also performed and, though the clips were not found, the polypoid tumour was removed through appendectomic orifice. The polyp thus removed, however, proved to be an adenoma. A repeated colonoscopy and biopsy confirmed both the localization clips and the malignant nature of the remaining right-sided lesion, which was finally removed with right hemicolectomy. CONCLUSION - Anatomic localization of rightsided colon cancers by colonoscopy is often imprecise. The correct identification of a malignant tumour may be compromised by a nearby benign lesion. If a lesion was labelled by some means, the localization sign should be identified both intraoperatively and during the gross pathologic work-up, asking for external help (e.g., radiology in case of a metal clip) if necessary.]

Isolated hypoglossal nerve palsy due to a jugular foramen schwannoma


Introduction – Although the involvement of the hypoglossal nerve together with other cranial nerves is common in several pathological conditions of the brain, particularly the brainstem, isolated hypoglossal nerve palsy is a rare condition and a diagnostic challenge. Case presentation – The presented patient arrived to the hospital with a history of slurred speech and an uncomfortable sensation on his tongue. Neurological examination showed left-sided hemiatrophy of the tongue with fasciculations and deviation towards the left side during protrusion. Based on the clinical and MRI findings, a diagnosis of hypoglossal nerve schwannoma was made. Discussion – Hypoglossal nerve palsy may arise from multiple causes such as trauma, infections, neoplasms, and endocrine, autoimmune and vascular pathologies. In our case, the isolated involvement of the hypoglossal nerve was at the skull base segment, where the damage to the hypoglossal nerve may occur mostly due to metastasis, nasopharyngeal carcinomas, nerve sheath tumors and glomus tumors. Conclusion – Because of the complexity of the region’s anatomy, the patient diagnosed with hypoglossal nerve schwannoma was referred for gamma knife radiosurgery.

Valproic acid associated pleuropericardial effusion: case report

DEMIR Figen Ulku

Introduction - Valproic acid is an effective antiepileptic and mood stabilizer used in the treatment of many neurological and psychiatric disorders. Although there are frequently seen side effects, effusions between layers of pleural and pericardial membranes are rare to be seen. Case - Pleuropericardial effusion was detected in a 23 years old woman who was under valproic acid treatment because of epileptic seizure. After 1 year of valproic acid treatment, patient complained of dyspnea. As all the researches intended on etiology were usual, valproic acid has been thought to be responsible for the matter. Control examination after 1.5 months regarding the end of treatment revealed complete recovery of pleuropericardial effusion. Discussion - Pleural and pericardial effusions are rarely seen complications related to the use of valproic acid. It must also be kept in mind that valproic acid causes a potential for such side effects which can be blamed etiologically when the other possibilities for patients are excluded.

The yield of electroencephalography in syncope

NALBANTOGLU Mecbure, TAN Ozturk Ozlem

Introduction - Syncope is defined as a brief transient loss of consciousness due to cerebral hypoperfusion. Although the diagnosis of syncope is based on a thorough history and examination, electroencaphalography (EEG) is also an important investigational tool in the differential diagnosis in this group of patients. In this study we aimed to identify the diagnostic value of EEG in patients with syncope. Methods - We retrospectively examined EEG recordings of 288 patients with the diagnosis of syncope referred to the Cankiri State Hospital EEG laboratory, from January 2014 to January 2016. The EEG findings were classified into 6 groups as normal, epileptiform discharges (spike and sharp waves), generalized background slowing, focal slowing, hemispherical asymmetries, and low amplitude EEG tracing. The EEGs were separated according to gender and age. Results - Total of 288 patients were included in this study, 148 were females (51.4%) and 140 (48.6%) were males. Among all the EEG reports, 203 (70.5%) were normal, 8 of them (2.8%) showed generalized background slowing and 7 (2.4%) demonstrated focal slow waves. Epileptiform discharges occured among 13 patients (4.5%). Hemispherical asymmetries were detected in 10 patients (3.5%) and low amplitude EEG tracing in 47 patients (16.3%). There was no significant difference between age groups in EEG findings (p=0.3). Also no significant difference was detected in EEG results by gender (p=0.2). Discussion - Although the diagnosis of syncope, epilepsy and non-epileptic seizures is clinical diagnosis, EEG still remains additional method

How to minimize the risk for headache? A lumbar puncture practice questionnaire study

JONATAN Salzer, RAJDA Cecilia, SUNDSTRÖM Peter, MATTIAS Vågberg, VÉCSEI László, ANDERS Svenningsson

Background - To lower the risk for post lumbar puncture (LP) headache the American Academy of Neurology (AAN) recommended using small bore atraumatic needles together with stylet reinsertion in a report from 2005. It is unclear whether these recommendations are followed or not. Objectives - To investigate the diagnostic LP preferences with respect to the AAN guidelines among neurologists by use of a short online questionnaire, and to review previously published literature on the subject. Results - A total of 284 respondents who performed diagnostic LPs completed the questionnaire. Almost half (41%) answered that they always use atraumatic needles. The most common reason (73%) for not using atraumatic needles was that these were not available. Less than half of the respondents who performed LPs had knowledge about the AAN guidelines for diagnostic LPs, and 48-76% agreed with the different recommendations therein. Five previously (1998-2015) published studies investigating LP practice among neurologists were identified. The reported frequency of atraumatic needle use (always/routinely) varied between 2 and 16%. Discussion - Atraumatic needle use was more common in this study compared with previous publications. There is still skepticism regarding some of the AAN recommendations, and needle availability appears to be the most important factor preventing atraumatic needle use. To increase the use of atraumatic needles we may perform additional studies investigating their potential benefits, and arrange training sessions for neurologists to increase their awareness and level of comfort with the atraumatic LP technique.

[Physical and electrophysiological aspects of electroconvulsive therapy (review)]


[Personnel and technical conditions for ECT (electroconvulsive therapy) is legally determined. In this article the author reviews studies focused on the technical questions of ECT. After the comparison of the unilateral and bilateral electrode placement an analysis is given on the physical properties of the stimulus used to elicit seizures. After discussing the questions of dose, vaweform frequency and polarity, the anatomical and physiological factors of impedance are evaluated. The author then discuss gender, age and encephalopathy as factors influencing seizure threshold. The connection between symmetry, regularity, and postictal suppression registered on the EEG and efficacy is observed. The EEG and EMG concordance is supposed to be connected also with the efficacy. In the discussion the author gives recommendations based on the literature.]
