Retinal morphological changes during the two years of follow-up in Parkinson’s disease

ATUM Mahmut, DEMIRYÜREK Enes Bekir

The study aims to investigate the relationship between the progression of idiopathic Parkinson’s disease (IPD) and retinal morphology. The study was carried out with 23 patients diagnosed with early-stage IPD (phases 1 and 2 of the Hoehn and Yahr scale) and 30 age-matched healthy controls. All patients were followed up at least two years, with 6-month intervals (initial, 6th month, 12th month, 18th month, and 24th month), and detailed neurological and ophthalmic examinations were performed at each follow-up. Unified Parkinson’s Disease Rating Scale part III (UPDRS Part III) scores, Hoehn and Yahr (H&Y) scores, best-corrected visual acuity (BCVA), intraocular pressure (IOP) measurement, central macular thickness (CMT) and retinal nerve fiber layer (RNFL) thickness were analyzed at each visit. The average age of the IPD and control groups was 43.96 ± 4.88 years, 44.53 ± 0.83 years, respectively. The mean duration of the disease in the IPD group was 7.48 ± 5.10 months at the start of the study (range 0-16). There was no statistically significant difference in BCVA and IOP values between the two groups during the two-year follow-up period (p> 0.05, p> 0.05, respectively). Average and superior quadrant RNFL thicknesses were statistically different between the two groups at 24 months and there was no significant difference between other visits (p=0.025, p=0.034, p> 0.05, respectively). There was no statistically significant difference in CMT between the two groups during the follow-up period (p> 0.05). Average and superior quadrant RNFL thicknesses were significantly thinning with the progression of IPD.

[The first Hungarian patient with Guillain-Barre syndrome after COVID-19]

NADIM Al-Muhanna, BÉRES-MOLNÁR Katalin Anna, JARECSNY Tamás, FOLYOVICS András

[Guillain-Barré syndrome (GBS) is a sporadic, relatively rare disease. In serious cases, it can lead to respiratory failure and death. The correlation between SARS-CoV-2 and the risk of GBS is not yet known. COVID-19-associated prolonged pulmonary complications could be worsened by the potential airway interference caused by GBS. The literature is inconsistent whether SARS-CoV-2 virus has direct or indirect effect on the onset of GBS. The authors describe the medical history of the first published GBS patient in Hungary with a preceding confirmed COVID-19 infection. The trigger role of COVID-19 infection is assumed because of the subsequent development of GBS after COVID-19 infection. So far none of the patients in the literature (including this patient) had positive PCR of SARS-CoV-2 virus from the cerebrospinal fluid.]

[Cases of inborn errors of metabolism diagnosed in children with autism ]

ÇAKAR Emel Nafiye, YILMAZBAŞ 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.]

The effects of 30 Hz, 50 Hz AND 100 Hz continuous theta burst stimulation via transcranial magnetic stimulation on the electrophysiological parameters in healthy individuals

OZDEMIR Zeynep, ACAR Erkan, SOYSAL Aysun

Transcranial magnetic stimulation is a non-invasive procedure that uses robust magnetic fields to create an electrical current in the cerebral cortex. Dual stimulation consists of administering subthre­shold conditioning stimulation (CS), then suprathreshold test stimulation (TS). When the interstimulus interval (ISI) is 1-6 msec, the motor evoked potential (MEP) decreases in amplitude; this decrease is termed “short interval intracortical inhibition” (SICI); when the ISI is 7-30 msec, an increase in MEP amplitude occurs, termed “short interval intracortical facilitation” (SICF). Continuous theta burst stimulation (cTBS), often applied at a frequency of 50 Hz, has been shown to decrease cortical excitability. The primary objective is to determine which duration of cTBS achieves better inhibition or excitation. The secondary objective is to compare 50 Hz cTBS to 30 Hz and 100 Hz cTBS. The resting motor threshold (rMT), MEP, SICI, and SICF were studied in 30 healthy volunteers. CS and TS were administered at 80%-120% and 70%-140% of rMT at 2 and 3-millisecond (msec) intervals for SICI, and 10- and 12-msec intervals for SICF. Ten individuals in each group received 30, 50, or 100 Hz, followed by administration of rMT, MT-MEP, SICI, SICF immediately and at 30 minutes. Greater inhibition was achieved with 3 msec than 2 msec in SICI, whereas better facilitation occurred at 12 msec than 10 msec in SICF. At 30 Hz, cTBS augmented inhibition and suppressed facilitation, while 50 Hz yielded less inhibition and greater inter-individual variability. At 100 Hz, cTBS provided slight facilitation in MEP amplitudes with less interindividual variability. SICI and SICF did not differ significantly between 50 Hz and 100 Hz cTBS. Our results suggest that performing SICI and SICF for 3 and 12 msec, respectively, and CS and TS at 80%-120% of rMT, demonstrate safer inhibition and facilitation. Recently, TBS has been used in the treatment of various neurological diseases, and we recommend preferentially 30 Hz over 50 Hz cTBS for better inhibition with greater safety and less inter-individual variability.

Neuroscience highlights: The mirror inside our brain

KRABÓTH Zoltán, KÁLMÁN Bernadette

Over the second half of the 19th century, numerous theories arose concerning mechanisms involved in understanding of action, imitative learning, language development and theory of mind. These explorations gained new momentum with the discovery of the so called “mirror neurons”. Rizzolatti’s work inspired large groups of scientists seeking explanation in a new and hitherto unexplored area of how we perceive and understand the actions and intentions of others, how we learn through imitation to help our own survival, and what mechanisms have helped us to develop a unique human trait, language. Numerous studies have addressed these questions over the years, gathering information about mirror neurons themselves, their subtypes, the different brain areas involved in the mirror neuron system, their role in the above mentioned mechanisms, and the varying consequences of their dysfunction in human life. In this short review, we summarize the most important theories and discoveries that argue for the existence of the mirror neuron system, and its essential function in normal human life or some pathological conditions.

[The role of anaerobic bacteria in brain abscesses: a literature review]

URBÁN Edit, GAJDÁCS Márió

[Brain abscesses are potentially serious, life-threatening diseases that pose a complex diagnostic challenge not only to neurosurgeons but also to clinical microbiologists, neurologists, psychiatrists, infectologists. The etiology of brain abscess is usually polymicrobial, most commonly involving a variety of aerobic and obligate anaerobic bacteria. Epidemiological studies on the anaerobic etiology of brain abscesses are common between the time period of 1960s and 1980s, but today there are very few new publications on the subject. The role of anaerobic bacteria in this disease was presumably underdiagnosed for a very long time, as many laboratories did not have the adequate laboratory capabilities for their cultivation and identification. The purpose of this review is to summarize the available literature on the etiology of obligate anaerobic bacteria in brain abscesses, including their prevalence and current therapeutic recommendations.]

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.

[Examination of the Strength of Core- and Perineal Muscles in Case of Different Movements]

KISS Noémi, BAJSZ Viktória, PAKAI Annamária, CSÁSZÁR Gabriella Edit

[Aims of the study: to measure the strength of core-, perineal muscles in three groups, to compare different exercises for the aspect of these muscles. 11 sedentary-, 10 women’s doing Pilates, 13 inactive female sudent’s core- and perineal muscles were measured in longitudinal study by DAVID-machine, modified Plank-test, FemiScan at Univerity of Pécs, Faculty of Health Sciences, Zalaegerszeg, 2016. february-november. Data analysis: ANOVA, Scheffe Post Hoc test, two-tailed T-test. The TS-group’s muscles became more symmetrical (p=0.043). According to Plank test, the TS-group’s 3th result became stronger than FH-group (p=0.001) and the PT-group (p=0.018) at first. About the perineal-muscles: usually the PT-group achieved the best results. The FH-group’s perineal-muscles in case of relaxation were significantly symmetrical (p=0.038) than the TS-group’s after training. Pilates-method turned out to be effective to improve the strength and stamina of core muscles. Core-training is effective to improve core muscles, but not enough for perineal muscles with the given frequency and intensity. ]

VARGA Bernadett, FUSZ Katalin, CSIMA Melinda, LUKÁCS-HORVÁTH Marianna, DEÁK András, STROMAJER-RÁCZ Tímea

[Hypertension is the best known risk factor in development of cardiovascular diseases and stroke. Survey has assessed –in hypertensive patients over 40, - the illness representation, lifestyle and medicine taking habits. Quantitative, cross-section descriptive research was conducted in 2017 with online questionnaire among hypertensive people over 40 (n=267) using shortened version of Brief Illness Perception Questionnaire, Morisky Medication Adherence Scale (8-item) and our questionnaire. Therapy adherence is typical for older individuals in surveyed population. (r= 0,26; p<0,001). Who were advised by general practitioners (GP) to implement lifestyle changes show more inclination following therapy. (p=0,032). Those with higher blood pressure (r-0,18; p=0,003) has harder time living with hypertension. (r=0,15; p=0,014). Quality of living with hypertonia and therapy adherence can be influenced by health behaviour and the information provided by general practitioners (GP). Beside the, general practitioners (GP) advanced practice nurse can have significant role in increasing the level of health behaviour and therapy adherence. ]

[The role of APN in the Care of Patients with High Blood Pressure]

VÖRÖS Tünde, PAKAI Annamária, SZEBENI-KOVÁCS Gyula, SZABÓNÉ Bálint Ágnes, OLÁH András

[Internationally the role of Advanced Practice Nurses (APN) has grown a lot in the treatment for high blood pressure. The tasks of Advanced Practice Nurses with an advanced degree include the observation, following, diagnostics, medicinal treatment, health education, education of patients, coordination of care, checking of performance and improvement of quality. In Hungary the family doctors do the care of people with hypertonia in the primary care. Because of the number of patients who must be treated every day comes less time per capita in the care. For a high number of acute patients must be cared and for this reason less time remains for the care of chronic patients. In Hungary the education for Advanced Practice Nurse (APN) with an advanced degree has started in autumn 2017. The first of these nurses will get out of the education in February 2019. Due to their education they will be able to care acute illnesses in practices of family doctors and in communities of practice. Besides they will be able to explore, care and follow chronic patients. ]
