Background - With improving treatment options, more attention is being paid to the neurocognitive symptoms related to hepatitis C infection (HCI). While HCI-related neurocognitive impairments are frequently subclinical, they can influence patients’ quality of life and fitness to work. Objective - The aim of this study was to assess HCI patients’ neurocognitive functions and explore the correlations between disease variables and neurocognitive symptoms. Method - The study was conducted between January 1, 2013 and December 31, 2015. All patients with HCI were included in the study who were registered at the Hepatology Outpatient Clinic of Szent István and Szent László Hospitals, met inclusion criteria and volunteered to participate. Patients’ sociodemographic data and medical history were recorded in a questionnaire designed for the study. The 21-item Beck Depression Inventory was used to detect depressive symptoms. Six computerized tests were used to evaluate patients’ neuropsychological functions. Results - Sixty patients participated in the study. In comparison with general population standards, patients demonstrated poorer performance in several neurocognitive tests. Neuropsychological performance was correlated with age, sex, length of time since HCI diagnosis, Fibroscan score and the number of previous antiviral treatments. Conclusions - The study’s main finding is that compared to general population standards, patients with hepatitis C virus-related disease exhibit impaired neuropsychological functioning in visuomotor and visuospatial functions, working memory, executive functions, and reaction time. Executive functions and reaction time were the most sensitive indicators for the length and severity of disease. Deterioration in these functions has a major negative effect on work performance particularly in certain occupations.

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.

MAHMUT Atum, ERKAN Çelik, GÜRSOY Alagöz

Introduction - Our aim is to present a rare case where a child had delirium manifestation after instillation of cyclopentolate. Case presentation - A 7-year old patient was seen in our outpatient clinic, and cyclopentolate was dropped three times at 10 minutes intervals in both eyes. The patient suddenly developed behavioral disorders along with gait disturbance, and complained of visual hallucinations 20-25 minutes after the last drop. The patient was transferred to intensive care unit and 0.02 mg/kg IV. physostigmine was administered. The patient improved after minutes of onset of physostigmine, and was discharged with total recovery after 30 minutes. Conclusion - Delirium is a rare systemic side effect of cyclopentolate. The specific antidote is physostigmine, which can be used in severely agitated patients who are not responding to other therapies.

The effects of the level of spinal cord injury on life satisfaction and disability

GULSAH Karatas, NESLIHAN Metli, ELIF Yalcin, RAMAZAN Gündüz, FATIH Karatas, MÜFIT Akyuz

Introduction - Spinal Cord Injury (SCI) may often lead to significant disability in affected individuals and reduce life satisfaction. Herein we aimed to investigate the effects of the level of injury on disability and life satisfaction as well as the relation between life satisfaction and disability. Methods - Patients with at least one-year history of SCI were included. Demographic-clinical data of patients were recorded. The Craig Handicap Assessment and Reporting Technique-Short Form (CHART-SF) was used for quantifying the degree of patients’ disability. Life satisfaction was assessed by the Satisfaction with Life Scale (SWLS). Results - Of the 76 patients, 21 (27.6%) were tetraplegic and 55 (72.4%) were paraplegic. SWLS was found to be similar in tetraplegic vs. paraplegic patients (P=0.59), whereas CHART parameters such as physical independence, mobility, occupation, and total CHART value were significantly higher in paraplegic patients (P=0.04, P=0.04, P=0.001 and P=0.01, respectively). Social integration was found similarly high in both groups. There was a positive correlation between elapsed time after the injury and CHART physical independence, occupation and the level of economic sufficiency (P<0.01, P<0.01, P=0.01). Excluding the economic sufficiency (P=0.02), there was not any other association between the rest of CHART parameters and SWLS. Conclusions - According to our findings, although the level of injury seems to be influential on disability, it seems to have no significant effect on life satisfaction. Since the only thing that positively affects life satisfaction is economic sufficiency, more emphasis should be placed on regulations that increase the return to work in patients.

Myasthenia gravis, Guillain-Barré syndrome, or both?

ERDOGAN Cagdas, TEKIN Selma, ÜNLÜTÜRK Zeynep, GEDIK Korkut Derya

Myasthenia gravis (MG) and Guillain-Barré syndrome (GBS) are autoimmune disorders that may cause weakness in the extremities. The coexistence of MG and GBS in the same patient has rarely been reported previously. A 52-year-old male presenting with ptosis of the left eye that worsened with fatigue, especially toward evening, was evaluated in our outpatient department. His acetylcholine receptor antibody results were positive, supporting the diagnosis of MG. His medical history revealed a post-infectious acute onset of weakness in four extremities, difficulty in swallowing and respiratory failure, which was compatible with a myasthenic crisis; however, his nerve conduction studies and albuminocytologic dissociation at the time were compatible with GBS. With this case report, we aimed to mention this rare coincidental state, discuss possible diagnoses and review all other similar cases in the literature with their main features.

[Current questions of multiple sclerosis: the secunder progressive form of the disease]

VÉCSEI László

[Recent data suggest that long-term worsening is common in relapsing-remitting multiple sclerosis patients and is largely independent of relapses or new lesion formation on brain MRI. The current definition of secunder progressive multiple sclerosis is worsening of disability independent of relapses over at least 6-month interval. Early focal inflammatory disease activity and spinal cord lesion are predictors of very-long term disease outcomes in relapse - onset multiple sclerosis. The potential of PET imaging to visualize hidden inflammation in MS brain in vivo is an important contribution for better understanding the progression of the disease. Therefore, PET imaging is a promising tool in detecting the conversion from relapsing remitting multiple sclerosis to secunder progressive form of multiple sclerosis. Furthermore, neuro-axonal damage is the pathological substrate of permanent disability in different neurological disorders including multiple sclerosis. The neurofilament proteins have promise in this context because their levels rise upon neuro-axonal damage not only in the cerebrospinal fluid but also in blood. Patients with increased serum levels of neurofilament at baseline, independent of other clinical and MRI variables, experience significantly more brain and spinal cord volume loss over 2 years and 5 years of follow-up. The kynurenine-pathway abnormalities may be associated with the swich from early-mild stage multiple sclerosis to debilitating progressive forms of the disease. Analysis of these metabolites in serum may have application as multiple sclerosis disease biomarkers. Free radical action has been suggested as a causal factor in the illness. Increased free radical production and consumption of the scavenger molecules were found during the active phase of the disease. Based on the clinical findings (EXPAND Study) and pathomechanism of the disease siponimod is approved by the US Food and Drug Administration for the treatment of relapsing remitting forms of multiple sclerosis, to include secunder progressive multiple sclerosis with active disease, relapsing-remitting multiple sclerosis and clinically isolated syndrome.]

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

Evaluation of the effectiveness of transforaminal epidural steroid injection in far lateral lumbar disc herniations

EVRAN Sevket, KATAR Salim

Far lateral lumbar disc herniations (FLDH) consist approximately 0.7-12% of all lumbar disc herniations. Compared to the more common central and paramedian lumbar disc herniations, they cause more severe and persistent radicular pain due to direct compression of the nerve root and dorsal root ganglion. In patients who do not respond to conservative treatments such as medical treatment and physical therapy, and have not developed neurological deficits, it is difficult to decide on surgical treatment because of the nerve root damage and spinal instability risk due to disruption of facet joint integrity. In this study, we aimed to evaluate the effect of transforaminal epidural steroid injection (TFESI) on the improvement of both pain control and functional capacity in patients with FLDH. A total of 37 patients who had radicular pain caused by far lateral disc herniation which is visible in their lumbar magnetic resonance imaging (MRI) scan, had no neurological deficit and did not respond to conservative treatment, were included the study. TFESI was applied to patients by preganglionic approach. Pre-treatment Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores of the patients were compared with the 3rd week, 3rd month and 6th month scores after the procedure. The mean initial VAS score was 8.63 ± 0.55, while it was 3.84 ± 1.66, 5.09 ± 0.85, 4.56 ± 1.66 at the 3rd week, 3rd month and 6th month controls, respectively. This decrease in the VAS score was found statistically significant (p = 0.001). ODI score with baseline mean value of 52.38 ± 6.84 was found to be 18.56 ± 4.95 at the 3rd week, 37.41 ± 14.1 at the 3rd month and 34.88 ± 14.33 at the 6th month. This downtrend of pa­tient’s ODI scores was found statistically significant (p = 0.001). This study has demonstrated that TFESI is an effective method for gaining increased functional capacity and pain control in the treatment of patients who are not suitable for surgical treatment with radicular complaints due to far lateral lumbar disc hernia.

Electrophysiological investigation for autonomic dysfunction in patients with myasthenia gravis: A prospective study

NALBANTOGLU Mecbure, AKALIN Ali Mehmet, GUNDUZ Aysegul, KIZILTAN Meral

Myasthenia gravis (MG) is an autoimmune disorder of neuromuscular transmission. Autonomic dysfunction is not a commonly known association with MG. We conducted this study to evaluate autonomic functions in MG & subgroups and to investigate the effects of acetylcholinesterase inhibitors. This study comprised 30 autoimmune MG patients and 30 healthy volunteers. Autonomic tests including sympathetic skin response (SSR) and R-R interval variation analysis (RRIV) was carried out. The tests were performed two times for patients who were under acetylcholinesterase inhibitors during the current assessment. The RRIV rise during hyperventilation was better (p=0.006) and Valsalva ratio (p=0.039) was lower in control group. The SSR amplitudes were lower thereafter drug intake (p=0.030). As much as time went by after drug administration prolonged SSR latencies were obtained (p=0.043).Valsalva ratio was lower in the AchR antibody negative group (p=0.033). The findings showed that both ocular/generalized MG patients have a subclinical parasympathetic abnormality prominent in the AchR antibody negative group and pyridostigmine has a peripheral sympathetic cholinergic noncumulative effect.
