Drop foot is defined as difficulty of dorsiflexion of the foot and ankle due to weak anterior tibial, extensor hallucis longus and extensor digitorum longus muscles. Cauda equina syndrome, local peroneal nerve damage due to trauma, nerve entrapment, compartment syndrome and tumors are common etiologies. A 32-year-old male patient was applied with difficulty in dorsiflexion of both of his toes, feet and ankles after he had squatted in toilette for 6-7 hours (because of his haemorrhoid) after intense alcohol intake 2 weeks before. Acute, partial, demyelinating lesion in head of fibula segment of peroneal nerves was diagnosed by electromyography. This case was reported since prolonged squatting is an extremely rare cause of acute bilateral peroneal neuropathy. This type of neuropathy is mostly demyelination and has good prognosis with physical therapy and mechanical devices, but surgical intervention may be required due to axonal damage. People such as workers and farmers working in the squatting position for long hours should be advised to change their position as soon as the compression symptoms (numbness, tingling) appear.
[Gait disturbance is a major symptom in patients with multiple sclerosis. The Expanded Disability Status Scale (EDSS) was first used in clinical trials of multiple sclerosis for the assessment of disability, however it has become more and more widely used in clinical practice as well. Nowadays its use is essential in application of the new diagnostic criteria, the new clinical form classification and in monitoring the efficacy of therapies. EDSS is based on a standardised neurological examination, but focuses on those symptoms that are frequent in multiple sclerosis. Based on the examination it assesses seven functional systems: visual, brainstem, pyramidal, cerebellar, sensory, bowel-bladder and cerebral functions. EDSS scores can be determined based on the scores given in the functional systems and on testing the walking distance. In newer versions the “Ambulation score” has been added. This chapter clarifies the scores based on the maximal walking distance and the need for a walking aid to walk this distance. The Neurostatus/EDSS training method improves the reproducibility of the standardised neurological examination that forms the basis of the EDSS scoring. Of the tests assessing walking, the Timed-25 Foot Walk Test and the self-administered 12-Item Multiple Sclerosis Walking Scale are suitable for routine evaluation of walking performance. An increase of more than 20% in the Timed-25 Foot Walk may be considered a significant change in gait. ]
Neurofibromatosis type 1 (NF-1; also known as Von Recklinghausen’s disease) is a common autosomal dominant disease that occurs in the general population at the rate of 1 in 3000. Many NF-1 patients present with spinal malformations. A 54-year-old female patient was admitted to the Outpatient Clinic of Dermatology with gradually increasing swelling and spots on the body that had been present for a long period of time. Cervical vertebral scalloping, pedicle deficiencies and dural ectasia (DE) were also detected. She was diagnosed with NF-1. NF-1 is routinely seen in dermatology practice. Coexistence of NF-1 with vertebral scalloping, pedicle deficiencies and DE rarely occurs. Our case is the second reported instance in the literature of NF-1 with a spinal anomaly in the cervical region, and the first reported instance of the coexistence of NF-1 with cervical vertebral scalloping, pedicle deficiencies and DE.
[Despite of the symptoms of vertigo have been known since thousands of years, it was evident by the research of the pioneer scientists of the 19th century (Flourens, Ménière, Breuer and others) that dizziness can also be attributed to inner ear disfunctions. The discovery of the vestibulo-ocular reflex was an important milestone (Endre Hőgyes, 1884). The vestibulo-ocular reflex stabilizes images on the retina by rotating the eyes at the same speed but in the opposite direction of head motion. The milestone discovery of Hőgyes by stimulating individual labyrinth receptors and recording the activity of eye muscles were verified by János Szentágothai in 1950. Low-frequency lesions of the angular vestibulo-ocular reflex can be investigated by caloric test (Robert Bárány,1906), high-frequency lesions by head impulse test (Gabor Michael Halmagyi and Ian Stewart Curthoys, 1988).]
Purpose - To understand if children with and without cerebral palsy share the same lumbar postural control threshold on the sagittal plane for the transition between each walking locomotor stage. Method - Observational analysis of sagittal trunk-pelvis kinematics of 97 children with cerebral palsy and 73 with typical development, according to their locomotor stage. Results - Among children with typical development, all average and minimum measurements of the sagittal lumbar curve during the gait events were correlated with age and the locomotor stages of development. Among children with cerebral palsy, there were significant correlations between all average and minimum values of the sagittal lumbar curve and locomotor stages of development but not age. Conclusions - We conclude that, for the same locomotor level, there are no common postural patterns between children with typical development and those with spastic bilateral cerebral palsy for the position between trunk and pelvis in the sagittal plane. Maximal lordosis reduction between trunk and pelvis may change with age or even training, but does not make a positive effect on the locomotor level, while basal and maintenance capacities could explain locomotor function. Trials that failed to assess quality of movement may now have a better understanding of how different interventions improve posture towards the next functional level.
[Aims - Overview of the new data about the strong link of sleep and epilepsy and conjoining cognitive impairment. Methods - Search for relevant references and summary of our own research activity on the topic. Results - Strong interrealtionship exists between epilepsy and plastic brain functions (memory processing and synaptic homeostasis) and the working modes of NREM sleep. In the most frequent childhood and adult epilepsy networks responsible for plastic functions can be derailed to an epileptic level of excitability, and suffer a transitory or permanent epileptic transformation. Exampling on the three big epilepsies: absence epilepsy; medial temporal lobe epilepsy; and childhood idiopathic focal age dependent epilepsy spectrum we demonstrate the most important features of this epileptic transformation. The association of cognitive impairment to certain sleep dependent epilepsies gains explanation by the epilepsy caused interference with slow wave decline (ICFE) and memory consolidation (MTLE) during NREM sleep. This paper serves also to introduce the concept of sleep dependent system epilepsies. Conclusions - We provide evidences about shared mechanisms among sleep related epilepsies being the derailment of sleep plastic funcions toward exaggerated excitability determined by the inherent possibilities of the signal transduction properties. ]
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.
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.
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.

[This study presents the complete history of the Hungarian vaccine production, partly in association with the process of fighting vaccine-preventable infectious diseases, and underlines the fact that every government actively contributed to the age-adjusted mandatory vaccination schedule of the past 140 years. It demonstrates the various achievements from the smallpox lymph production through the launch of diphtheria serum production at Phylaxia and the establishment of the National Public Health Institute (OKI) with its vaccine production and the later institutional transformation of OKI into Humán as economic corporation to its closure. Among all OKI’s vaccine production activities, this study focuses on the production of influenza vaccines, due to its international importance in the 1960s and 1970s. The vaccine production against diphtheria tetanus and pertussis stands out from Humán’s activities, and the tetanus component of this vaccine is still used in the products of a multinational vaccine manufacturer. ]

[Three decades ago, LAM was launched with the goal of providing scientific information about medicine and its frontiers. From the very beginning, LAM has also concerned a special subject area while connecting medicine with the world of art. In the palette of medical articles, it remained a special feature to this day. The analysis of the history of LAM to date was performed using internationally accepted publication guidelines and scientific databases as a pledge of objectivity. We examined the practice of LAM if it meets the main criteria, the professional expectations of our days, when publishing contents of the traditional printed edition and its electronic version. We explored the visibility of articles in the largest bibliographic and scientific metric databases, and reviewed the LAM's place among the Hungarian professional journals. Our results show that in recent years LAM has gained international reputation despite publishing in Hungarian spoken by a few people. This is due to articles with foreign co-authors as well as references to LAM in articles written exclusively by foreign researchers. The journal is of course full readable in the Hungarian bibliographic databases, and its popularity is among the leading ones. The great virtue of the journal is the wide spectrum of the authors' affiliation, with which they cover almost completely the Hungarian health care institutional system. The special feature of its columns is enhanced by the publication of writings on art, which may increase Hungarian and foreign interest like that of medical articles.]
