Clinical Neuroscience - 1954;7(06)

[1. the author reviewed 14 cases of poly-neuritis of different aetiology and searched for a correlation between the quality and localisation of histological lesions and the aetiological factor. 2 Histopathological examination of all sections of the surrounding nervous system except terminal neuropathways was performed from three main aspects: a) quality of histological lesion - inflammation or degeneration, b) localization of the pathological process, c) axonal lesion and axonal retrograde cell changes. 3. 7 cases showed severe degeneration of the parenchyma of the surrounding nervous system with axonal cell changes. The site of the degeneration was the peripheral nerve (distal typus degeneration). In these cases, arsenic, achylia gastrica, hypovitaminosis, anaemia were aetiological factors. 4. 6 cases had generalized serous inflammation of the peripheral nervous system in the foreground of the histological picture, associated with degeneration of the medullary sheath and axodilatation without retrograde cellular changes. In contrast to the previous group, the degeneration was most severe in the dural sheath and in the root (proximal tympanic degeneration). The author, in agreement with Scheinker and Sántha, seeks an explanation for the proxymal radicular marrow degeneration in that the swollen root is strangulated in the dural sheath. In these cases, an allergic reaction (after influenza, pneumonia, tonsillitis, ulcus molle, gastritis) is postulated as the aetiological factor. The last case corresponds to polyganglinitis, in which a viral origin is likely. 5. Histopathological examination of the cases shows that the aetiological factors which primarily cause the metabolic abnormalities of the nervous system are those which cause a distal-type parenchymal degenerative process of the surrounding nervous system. As a consequence of an allergic reaction or infection, a radicular interstitial inflammatory process develops. 6 To distinguish between these two processes, the author, following Lewy and Wechsler, considers it appropriate to call the first group of cases 'polyneuropathy' and the latter 'polyganglioradiculitis' (as explained in the text), on the basis of the localisation of the degenerative lesions.]

[Central nervous system and RES. I. Nervous system regulation of liver RES]

CSABA György, RAPPAY György

[Our experiments were carried out on 80 healthy white rats, males and females. The aim of our experiments was to determine the neuromuscular influence and regulation of reticuloendathelium. The experimental methodology used was the stabilized Törő-Velősy procedure. By surgically and pharmacologically performing the experiments with subcortical agents, we found that: 1. RES (hepatic RES) is under the regulation of the central nervous system. 2. Sympathetic excitation increases and parasympathetic excitation decreases RES activity.]

[Multinucleated sympathetic ganglion cell in humans]

HARSÁNYI László

[In view of the foregoing, it must therefore be concluded, contrary to previous observations, that the formula in the cervical sympathetic ganglia of healthy adult humans, also in the ggl. c. sup., can be regarded as an abnormal element and its formation is presumably due to a cell division disorder.]

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.

[The role of sleep in the relational memory processes ]

ZÁMBÓ Ágnes, PROKECZ Lídia, CSÁBI Eszter

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]

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.
