RESUMO

BACKGROUND: Neuropathy affects 25% of people with diabetes mellitus. The evaluation of disease severity is still a challenge for modern medicine. Many screening instruments are based primarily on clinical criteria. There is a lack of a simple, reliable and precise scoring system that could improve the classification of neuropathy and monitor disease progression using not only clinical criteria but also electroneurography. There is a need to find sensitive neurography parameters that reflect peripheral nerve impairments in this group of patients. OBJECTIVES: This study aimed to create a scoring system for diabetic neuropathy, based on electroneurography criteria, that reflects the natural course of the disease. A new scoring system will improve the treatment of patients with diabetes mellitus. MATERIAL AND METHODS: A total of 113 patients with distal symmetrical polyneuropathy (DSPN) were involved in the study. Median, ulnar, sural, tibial, and peroneal nerves were examined. Parameters such as amplitude, conduction velocity, distal latency, and F wave latency were analyzed. The results of nerve conduction studies in the investigated group were compared to those of the control group, which consisted of 61 healthy volunteers. RESULTS: The most sensitive parameter of peripheral nerve impairment severity was a reduction of the sensory action potential amplitude in the peroneal nerve by 72.8% (p < 0.05). The observation of changes in sensory action potential amplitudes in the peroneal nerve is the most important element of our scoring system. CONCLUSIONS: A new electroneurography scoring system of DSPN severity should be based on sensory and motor action potential amplitudes that reflect axonal loss in the examined nerves and the nature of the disease.

RESUMO

Various neurological manifestations are observed in about 36.4% of patients infected with SARS-CoV-2 and post-COVID neuropathy is one of them. There is lack of studies describing neurophysiological abnormalities in peripheral nerves in case of patients who had SARS-CoV-2 infection. The aim of this study was to analyze the changes in peripheral nervous system in case of COVID-19 survivors. In the presented study, 45 COVID-19 survivors who had nerve conduction study (NCS) were involved. Results were compared with control group consisting of healthy patients who had nerve conduction study before the COVID-19 pandemic. In our study group, neurophysiological abnormalities were present in the case of both sensory and motor nerve fibers. The most significant reduction of NCS parameters was observed in the case of sensory action potential amplitude of sural nerve. Moreover, that correlation was the most significant in the case of amplitude and conduction velocity in sensory and motor neuron fibers both in arms and legs. Those abnormalities were observed even 6 mo after COVID-19. Further investigation needs to be done regarding the polyneuropathies associated with human coronaviruses, and we should answer the question whether the virus directly damages peripheral nerves or factors mediating inflammatory response are responsible for the neural damage.NEW & NOTEWORTHY Various neurological manifestations are observed in about 36.4% of patients infected with SARS-CoV-2 and post-COVID neuropathy is one of them.

RESUMO

Interferometric near-infrared spectroscopy (iNIRS) is an optical method that noninvasively measures the optical and dynamic properties of the human brain in vivo. However, the original iNIRS technique uses single-mode fibers for light collection, which reduces the detected light throughput. The reduced light throughput is compensated by the relatively long measurement or integration times (∼1 sec), which preclude monitoring of rapid blood flow changes that could be linked to neural activation. Here, we propose parallel interferometric near-infrared spectroscopy (πNIRS) to overcome this limitation. In πNIRS we use multi-mode fibers for light collection and a high-speed, two-dimensional camera for light detection. Each camera pixel acts effectively as a single iNIRS channel. So, the processed signals from each pixel are spatially averaged to reduce the overall integration time. Moreover, interferometric detection provides us with the unique capability of accessing complex information (amplitude and phase) about the light remitted from the sample, which with more than 8000 parallel channels, enabled us to sense the cerebral blood flow with only a 10 msec integration time (∼100x faster than conventional iNIRS). In this report, we have described the theoretical foundations and possible ways to implement πNIRS. Then, we developed a prototype continuous wave (CW) πNIRS system and validated it in liquid phantoms. We used our CW πNIRS to monitor the pulsatile blood flow in a human forearm in vivo. Finally, we demonstrated that CW πNIRS could monitor activation of the prefrontal cortex by recording the change in blood flow in the forehead of the subject while he was reading an unknown text.

RESUMO

Monitoring of human tissue hemodynamics is invaluable in clinics as the proper blood flow regulates cellular-level metabolism. Time-domain diffuse correlation spectroscopy (TD-DCS) enables noninvasive blood flow measurements by analyzing temporal intensity fluctuations of the scattered light. With time-of-flight (TOF) resolution, TD-DCS should decompose the blood flow at different sample depths. For example, in the human head, it allows us to distinguish blood flows in the scalp, skull, or cortex. However, the tissues are typically polydisperse. So photons with a similar TOF can be scattered from structures that move at different speeds. Here, we introduce a novel approach that takes this problem into account and allows us to quantify the TOF-resolved blood flow of human tissue accurately. We apply this approach to monitor the blood flow index in the human forearm in vivo during the cuff occlusion challenge. We detect depth-dependent reactive hyperemia. Finally, we applied a controllable pressure to the human forehead in vivo to demonstrate that our approach can separate superficial from the deep blood flow. Our results can be beneficial for neuroimaging sensing applications that require short interoptode separation.

RESUMO

Visual stimulation is one of the most commonly used paradigms for cerebral cortex function investigation. Experiments typically involve presenting to a volunteer a black-and-white checkerboard with contrast-reversing at a frequency of 4 to 16 Hz. The aim of the present study was to investigate the influence of the flickering frequency on the amplitude of changes in the concentration of oxygenated and deoxygenated hemoglobin. The hemoglobin concentrations were assessed with the use of a high resolution diffuse optical tomography method. Spatial distributions of changes in hemoglobin concentrations overlaying the visual cortex are shown for various stimuli frequencies. Moreover, the hemoglobin concentration changes obtained for different source-detector separations (from 1.5 to 5.4 cm) are presented. Our results demonstrate that the flickering frequency had a statistically significant effect on the induced oxyhemoglobin changes (p < 0,001). The amplitude of oxy hemoglobin concentration changes at a frequency of 8 Hz was higher in comparison with that measured at 4 Hz :[median(25th-75thpercentiles) 1.24 (0.94-1.71) vs. 0.92(0.73-1.28)µM, p < 0.001]; 12 Hz:[1.24 (0.94-1.71) vs. 1.04 (0.78-1.32) µM, p < 0.001]; and 16 Hz:[1.24 (0.94-1.71) vs. 1.15(0.87-1.48) µM, p < 0.001]. No significant differences were observed between the size of an area of activation for various frequencies. The demonstrated superiority of 8 Hz over other frequencies can advance understanding of visual stimulations and help guide future fNIRS protocols.

RESUMO

INTRODUCTION: Malignant ischemic stroke of the middle cerebral artery (MCA) territory causes neurological deterioration due to the effects of space occupying cerebral edema. The prognosis is poor, and death usually occurs as a result of brainstem compression. There is no information on ischemic stroke, especially the malignant ones, in patients over 85 years old. AIM: The aim of this retrospective study was to evaluate the disease course, risk factors, survival rate and treatment of MCA malignant infarction in people over 85 years old. METHOD: The medical history of 66 patients with malignant MCA stroke was analyzed. The frequency of the occurrence of the risk factors like hypertension, hyperlipidemia, atrial fibrillation, heart failure, diabetes was evaluated. Disability was measured with the use of the National Institutes of Health Stroke Scale (NIHSS). Safety and effectiveness of the anticoagulants used in the group of patients with atrial fibrillation were analyzed. Chi-quadrat test and Mann-Whitney U test were used for statistical analysis of data. We also described 85 year-old patient with malignant brain stroke who was treated neurosurgically with a positive effect. RESULTS: Atrial fibrillation was diagnosed in 65% of patients of the investigated group. There were no statistically significant changes in the survival rate between the group of patients treated with the use of mannitol and patients without this treatment. CONCLUSION: The key risk factor in this group is the atrial fibrillation. The elderly patients require an intensive monitoring of the health condition by reference to brain stroke risk factors, especially atrial fibrillation.

RESUMO

BACKGROUND: Post polio syndrome is a rare disease that occurs decades after polio virus infection. Repetitive transcranial magnetic stimulation (rTMS) is a treatment option with proved effectiveness in drug resistant depression. Possibly it can be helpful in therapy of other neurological diseases including post polio syndrome. OBJECTIVE: To describe a case of patient diagnosed with post polio syndrome who was treated with rTMS stimulation with a good effect. METHODS: Patient had rTMS stimulation of left prefrontal cortex twice a week for an eight weeks. Patient's health status was evaluated before treatment, after last rTMS session and after three months from the end of the treatment. RESULTS: Improvement of fatigue score, mood disturbances and motor functions was observed after treatment. CONCLUSION: rTMS can be an effective method in treatment of post polio syndrome but further studies with larger group need to be done to confirm that data.

RESUMO

INTRODUCTION: The European population is aging and the number of elderly patients suffering from ischemic brain stroke increases. A better knowledge of the correlation between the risk factors and the course of the disease in old people may be useful for planning medical care and prophylactic strategies. AIM: This prospective study aimed to perform a demographic and clinical analysis of the etiology of ischemic stroke, survival rate and severity of post-stroke disability in patients who developed ischemic stroke at the age of over 85 years in the Polish population. METHOD: The study group consisted of 159 patients over 85 years old with ischemic stroke. The prevalence of risk factors such as sex, hypertension, hyperlipidemia, atrial fibrillation, heart failure and diabetes was evaluated. The outcome was assessed using the Barthel scale and the National Institutes of Health Stroke Scale. RESULTS: The most common risk factors of ischemic stroke were hypertension and atrial fibrillation. Patients with atrial fibrillation had a more severe course of ischemic stroke. CONCLUSION: The course of brain stroke in the Polish population is more severe in patients over 85 years old than in younger ones. The key risk factor in this group is atrial fibrillation.

RESUMO

Usually limbic encephalitis (LE) is a paraneoplastic neurologic syndrome. LE symptoms can precede cancer even by a few years. Almost 50% of LE cases are connected with small cell lung carcinoma. Testis and breast cancers, granulomatous disease, thymoma, and teratomas are also often connected with LE. Other cases have infectious and autoimmunological aetiology. In LE limbic system dysfunction is observed, and it is accompanied by cerebellum and brain stem abnormalities as well as polyneuropathy. Paraneoplastic limbic encephalitis is sometimes a part of larger syndrome in which brain stem and spinal cord are involved in an inflammatory process called paraneoplastic encephalomyelitis. The main LE symptoms are: impairment of cognitive functions with subacute beginning, partial and generalised seizures, mental distress, disturbances of consciousness, and limb paresis. In MRI study hyperintensive lesions in the medial part of the temporal lobes in T2 and FLAIR sequences are present. Sharp and slow waves in electroencephalography in the temporal area are also frequent. In cerebrospinal fluid pleocytosis, elevation of protein level, intensification of immunoglobulin synthesis, and oligoclonal bands can be detected. The majority of patients with paraneoplastic LE have onconeural antibodies in the blood. The presented study is a description of the clinical course of the disease in four patients diagnosed with LE.

RESUMO

Brain stroke connected with aortic blood flow disturbances is a rare disease and its incidence is difficult to assume. Nevertheless, 10-50% of patients with aortic dissection may not experience any pain. In case of 18-30% patients with aortic dissection neurological signs are first disease presentation and among them ischemic stroke is the most common. The most popular aortic dissection classification is with use of Stanford system. Type A involves the ascending aorta and type B is occurring distal to the subclavian artery. Aortic dissection risk factors include hypertension, cystic medionecrosis, bicuspid aortic valve and Marfan's or Ehlers-Danlos syndrome.

RESUMO

Creutzfeldt-Jakob disease (CJD) is a rare syndrome of central nervous system caused by infectious protein called prion. There are four types of CJD: sporadic (sCJD), familial (fCJD), jatrogenic (jCJD) and variant (vCJD). The most frequent symptoms are rapidly progressing dementia, mioclonias, akinetic mutism and signs of cerebellum dysfunction. In sCJD, MRI often shows high signal intensity in the putamen and caudate nucleus on T2-weighted images while in vCJD pulvinar sign is often observed. 70% patients with CJD often has characteristic generalized periodic sharp wave pattern in electroencephalography. In case of 90% patients with CJD 14-3-3 protein is present in cerebrospinal fluid. Neuropathological studies play an important role in disease diagnosis. CJD incidence is 0.5-1 on 1000000 people but some cases can be undiagnosed. Presented study is a description of woman with sCJD confirmed with histopathological study. Since childhood patient had psychotic symptoms and behavior disturbances. Patient wasn't diagnosed due to this symptoms. Few months before admission to hospital her condition was getting worse. Symptoms of cerebellum, pyramidal and extrapyramidal system occurred. In cerebrospinal fluid 14-3-3 protein was detected. In EEG and MRI changes specific for sCJD was observed. After three months patient died.

RESUMO

It is estimated that around 15 million people survived polio infection worldwide since early twentieth century. In 1950 effective vaccination was used for first time. Since that time number of affected people decreased. The last epidemic of Haine-Medine disease in Poland was in 1950s. Another rare cases of infections were observed till 1970s. About at least 15 years after polio virus infection, slowly progressive muscle limbs paresis with muscle atrophy, joints pain, paresthesia were observed in polio survivors. That constellation of symptoms was called post-polio syndrome (PPS). PPS frequency among people after paralytic and nonparalytic polio infectious is ranged from 30% to 80%. Fatigue that leads to physical and mental activity deterioration is another important symptom that is observed in 90% of patients with PPS. Etiology of disease remains elusive. Probably it is an effect of spine frontal horns motoneurons damage during acute virus polio infection that leads to overloading and degeneration of remaining ones. The most important risk factors of PPS are female sex and respiratory symptoms during acute polio infection. Electromyography is an important part of PPS diagnostic process. Electrophysiological abnormalities are seen in clinically affected and unaffected muscles. The most frequent are fasciculations and fibrillations during rest activity, extension of motor unit area, time duration and amplitude. In this study we described three cases of people who developed PPS years after Haine-Medine disease and correlation between their EMG results and clinical status. We also analyzed electromyography results both after one month since first PPS signs occurred as well as after few years. Presentation of dynamic changes in EMG was the most important aim of that study.

RESUMO

Repetitive transcranial magnetic stimulation (rTMS) is a treatment option with proved effectiveness especially in drug resist depression. It is used in functional brain mapping before neurosurgery operations and diagnostic of corticospinal tract transmission. Many studies are performed to evaluate rTMS using in treatment of obsessive - compulsive disorder, schizophrenia, autism, strokes, tinnitus, Alzheimer and Parkinson diseases, cranial traumas. Moreover rTMS was used in treatment of multiple sclerosis, migraine, dystonia. Electromagnetical field generated by rTMS penetrate skin of the scalp and infiltrate brain tissues to a depth of 2 cm, cause neurons depolarization and generating motor, cognitive and affective effects. Depending on the stimulation frequency rTMS can stimuli or inhibit brain cortex. rTMS mechanism of action remains elusive. Probably it is connected with enhancement of neurotransmitters, modulation of signals transductions pathways in Central Nervous System, gene transcription and release of neuroprotective substances. Studies with use of animals revealed that rTMS stimulation can generate brain changes similar to those seen after electric shock therapy without provoking seizures. The aim of presenting study was to analyze actual researches evaluating rTMS use in treatment of psychiatric and neurological diseases.

RESUMO

Multiple sclerosis is a chronic, autoimmunological disease of central nervous system in which axonal damage in brain and spinal cord is observed. It is second most common cause of disability in young adults in West Europe and North America after injuries. There is 2.5 million people suffered from multiple sclerosis worldwide. The worse prognosis is connected with primary progressive MS in which recovery after first symptoms of central nervous system damage isn't observed. That subtype of disease is seen in case of 10-20% people with MS. MTX is a synthetic antracycline with antineoplastic, immunomodulatory and anti-inflammatory effects. Drug was allowed to treatment of leukemia. It is also used in treatment of breast, prostate, ovarian, stomach and liver cancer. Additionally MTX is used in treatment of secondary progressive SM and relapsing - remitting subtype of disease with no respond to treatment with interferon beta and glatiramer acetate. MTX inhibits topoisomerase II activity, matches to DNA molecule and damage her structure. Drug inhibits limphocyte T, B and macrophages activity and antibodies synthesis. The most dangerous side effects of MTX treatment are cardiotoxicity and induction of leukemia. There is lack of studies describing MTX effectiveness and safety in treatment of primary progressive SM.

RESUMO

BACKGROUND: Mitoxanthrone (MTX) is a synthetic anthracycline antibiotic that has been used for several years in the treatment of patients with primary progressive, secondary progressive, and relapsing remitting multiple sclerosis (MS) who do not respond to other drugs. MTX has antineoplastic, immunomodulatory, and antibacterial properties. The most common adverse effects of MTX include nausea and vomiting, hair loss, increased risk of urinary and respiratory tract infections, and amenorrhea. Less frequent problems include leukopenia, thrombocytopenia, anaemia, and an increase in hepatic enzyme and bilirubin levels. Other severe sequelae of MTX treatment are drug cardiotoxicity and a potential to induce leukaemia. Drug toxicity results from its affinity to iron ions. The resulting complex strongly induces formation of free oxygen radicals and increases lipid peroxidation. Asymptomatic reduction in left ventricular ejection fraction (LVEF) by two-dimensional (2D) echocardiography, cardiomyopathy, and congestive heart failure have been observed in patients with MS at a rate of about 2.6-5%. Few studies evaluated cardiotoxicity of MTX in MS patients. Most previous studies were performed in small groups of cancer patients and cardiac evaluation was limited to physical examination. AIM: To evaluate the effect of MTX treatment on LVEF by 2D echocardiography. METHODS: We studied 72 MS patients aged 25-63 years who were treated with MTX in 2002-2014. The diagnosis of MS was made using the 2001 McDonald criteria updated in 2005. The study group included primary progressive MS in 40 (56%) patients, secondary progressive MS in 5 (7%) patients, and relapsing remitting MS in 27 (37%) patients. MTX was administered at 12 mg/m2 of body surface area every 3 months (up to the total dose of 140 mg/m2). MTX treatment was initiated in patients with no signs of heart failure on physical examination, normal electrocardiogram (ECG), normal LVEF by 2D echocardiography, and normal laboratory test findings including complete blood count and hepatic and renal function parameters. Each MTX administration was preceded by 2D echocardiography with LVEF measurement, ECG, and physical examination of the cardiovascular system. The effect of MTX treatment on LVEF was evaluated by comparing baseline LVEF with LVEF measurements before the last MTX dose. Statistical analysis was performed using the Student t test. RESULTS: The mean LVEF before administration of the first MTX dose was 65 ± 3.3%. The lowest LVEF at the final 2D echo-cardiographic examination was 60 ± 2.1%. We did not find a significant LVEF reduction during MTX treatment in MS patients compared to baseline values. Severe myocardial dysfunction manifesting with significant LVEF reduction by 2D echocardiography or clinical evidence of heart failure was not noted in any patient in the study group. CONCLUSIONS: Our study showed no significant LVEF reduction during MTX monotherapy in MS patients without a history of a cardiac disease and with normal echocardiographic findings at baseline. Long-term cardiac effects of MTX require further studies.

RESUMO

Multiple sclerosis (MS) is an inflammatory, demyelinating disease that affects the central nervous system. Etiology of MS is undiscovered but it is assumed that both genetic and environmental triggers play an important role in disease pathogenesis. Mitoxantrone (MTX) is an antracycline antibiotic that is used in oncologic treatment of breast, prostate, liver, ovarian and stomach cancer. MTX is also effective in treatment of primary and secondary progressive multiple sclerosis and in relapsing - remitting subtype of disease with no reaction for other drugs therapy. In treatment of MS drug is given intravenously in a dose of 12 mg/m2 in three months intervals to maximal dose of 120-140 mg/m² of body surface. MTX treatment can cause transient reduction of leukocyte, erythrocyte and thrombocyte number in blood but the most dangerous side effect of MTX treatment is therapy related acute leukemia (TRAL). The aim of this study was to evaluate influence of MTX treatment on complete blood count in multiple sclerosis patients. Seventy two patients with multiple sclerosis treated with mitoxantrone from 2002 to 2014 took part in this study. Control group comprised 60 patients with multiple sclerosis who weren't given immunomodulatory treatment. In this study, amount of leukocytes, erythrocytes and thrombocytes after MTX treatment was compared to those before treatment and in control group. Six patients were withdrawn from the study because of leucopenia. A decrease of leukocytes, erythrocytes and thrombocytes number after MTX treatment was observed in comparison to control group and value before treatment. The decrease of erythrocytes number after MTX treatment was statistically significant. The most frequent side effect of mitoxantrone treatment is transient, asymptomatic leucopenia. Therapy related acute leukemia and other life-threatening complications weren't observed in the study group.

RESUMO

Post-polio syndrome occurs 30-40 years after polio virus infection. The main symptoms of PPS are slowly progressive muscle limbs paresis with muscle atrophy, joints pain, paresthesia. In 90% of patients the main symptom is fatigue that leads to physical and mental activity deterioration. The cause of disease remains unknown. Probably it is an effect of motoneurons damage during acute virus polio infection, their overloading and degeneration of remaining ones. In this study we described a case of man who developed PPS 36 years after Heine-Medin disease. The main symptom was intensification of right limb paresis and muscle atrophy. In electromyography there were damage features of muscle clinically affected and unaffected. Changes in lifestyle made possible to continue occupational activity.

RESUMO

UNLABELLED: Brain tumor is an abnormal growth of cells in central nervous system (CNS). The most common primary brain tumors are: gliomas, meningiomas, pituitary adenomas and craniopharyngiomas. The secondary group are metastatic tumors. About 25% patients with cancers have metastasis to CNS. AIM: The aim of this study was to evaluate the most common symptoms and localization of brain tumors, time from first symptoms to diagnosis and patients' survival rate. MATERIALS AND METHODS: In this retrospective study 106 patients with primary and metastatic brain tumors hospitalized in Military Institute of Medicine from 2007 to 2012 year were investigated. RESULTS: The most common cause of metastases to brain is non-smallcell lung carcinoma. The most frequent symptom of brain tumor is headache but very often patients have seizures, vomits, arms and legs weakness. The mean time of life for patients with gliomas was 9 month and 13 days for patients with brain metastases. CONCLUSIONS: It occurred that patients with primary and secondary brain tumors lived shorter than it is described in literature. In group of patients with metastases to brain 60% had one or two brain tumors so they could be treated with surgery and prognosis for them was better.

RESUMO

Amyothropic neuralgy is a rare disease witch unknown etiopathogenesis. The main popular theory says that inflammatory and immunomodulatory process is connected with that disease. Diagnosis is made after exclusion of other causes of plexus lumbosacralis damage. The main symptom is neuropathic pain after which there is observed muscle weakness and atrophy. ENG/EMG study and MRI are made to confirm the diagnosis. In this study we described a case of 52 years old female with lower limbs paresis, who was diagnosed few years after first symptoms. Limb paresis was preluded by lumbar pain. MRI study revealed central spinal disc herniations on L1-2, L2-3, L3-4 levels with dura matter compression, L4-5 spinal disc right lateral herniation and synovial cyst. MRI of both lumbar plexuses was also normal. EMG study revealed features of bilateral, chronic damage of lower legs nerves on lumbar plexus level. Patient was treated with physiotherapy and gabapentin with dose of 2x600mg per day.
