Investigation of cerebellar damage in adult amyotrophic lateral sclerosis patients using magnetic resonance imaging and diffusion tensor imaging.

BACKGROUND: Research on amyotrophic lateral sclerosis (ALS) reveals that the disorder is not restricted to motor neurons. OBJECTIVES: This neuroimaging study aimed to investigate the presence of cerebellar damage in adult ALS patients. MATERIAL AND METHODS: The study retrospectively analyzed magnetic resonance imaging (MRI) examinations performed on a 1.5T MR unit of 33 patients (17 men and 16 women with a mean age of 59.3 years) diagnosed with ALS. Cerebellar and posterior fossa dimensions were calculated using plain MR images. In addition, diffusion tensor imaging (DTI) was used to obtain white matter integrity measurements, represented as fractional anisotropy (FA) values, in the posterior limbs of internal capsules (PLIC) and middle cerebellar peduncles (MCPs). These measurements were compared to 36 healthy volunteers (11 men and 25 women with a mean age of 55.3 years). The study also assessed clinical data for correlations with cerebellar imaging findings. RESULTS: The linear measurements of the cerebellum did not differ between groups. However, the transverse cerebellar dimension (TCD) ratio to the maximum length of the posterior fossa (0.973 compared to 0.982, t = -2.76, p < 0.01) and FA value in both MCPs (0.67 compared to 0.65 and 0.69 compared to 0.67, p < 0.05) were significantly lower in ALS patients. No significant differences were found in FA value in the PLIC, and no significant correlations were observed between patient clinical characteristics and cerebellar damage. CONCLUSION: This study provides evidence of cerebellar damage in adult ALS patients. These findings contribute to ALS understanding and highlight the importance of considering cerebellar involvement in the disease process. The results suggest that measuring the TCD ratio and FA value in both MCPs could be potential biomarkers for cerebellar damage in ALS patients.

The impact of clinical education on knowledge and attitudes towards brain death among Polish medical students - a cross-sectional study.

BACKGROUND: Understanding brain death is essential for progress in organ transplantation; however, it remains a challenging ethical matter. In 2019, Poland revised its legislation on brain death to align with international standards. This study aimed to evaluate the knowledge and worldview concerning brain death among Polish medical students, categorised according to their stage of education. METHODS: An online questionnaire was administered to 169 medical students from four Polish medical universities. The participants were divided into preclinical (n = 94) and clinical (n = 75) groups. The questionnaire consisted of two parts, with the first part comprising 13 questions focusing on knowledge about brain death and the process of its determination. The second part contained six questions related to the participants' worldview regarding brain death, particularly concerning organ transplantation. RESULTS: The average score obtained by the respondents was 7.53 (± 2.35; min. 1, max. 13) in knowledge checking part of the developed questionnaire (maximal score:13). Students in the clinical stage of their education achieved significantly higher scores compared to preclinical students (mean 8.84; ± 1.89 vs mean 6.49; ± 2.15; p < 0.001). Significant correlations were found between the results of the knowledge part of the questionnaire and responses to worldview questions. CONCLUSIONS: The stage of education influenced the knowledge of brain death among medical students, although the overall test scores were unsatisfactory. Higher test scores were associated with worldview responses indicating compliance with the current legislation in Poland and evidence-based medicine.

Molecular, Electrophysiological, and Ultrasonographic Differences in Selected Immune-Mediated Neuropathies with Therapeutic Implications.

The spectrum of immune-mediated neuropathies is broad and the different subtypes are still being researched. With the numerous subtypes of immune-mediated neuropathies, establishing the appropriate diagnosis in normal clinical practice is challenging. The treatment of these disorders is also troublesome. The authors have undertaken a literature review of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), Guillain-Barre syndrome (GBS) and multifocal motor neuropathy (MMN). The molecular, electrophysiological and ultrasound features of these autoimmune polyneuropathies are analyzed, highlighting the differences in diagnosis and ultimately treatment. The immune dysfunction can lead to damage to the peripheral nervous system. In practice, it is suspected that these disorders are caused by autoimmunity to proteins located in the node of Ranvier or myelin components of peripheral nerves, although disease-associated autoantibodies have not been identified for all disorders. The electrophysiological presence of conduction blocks is another important factor characterizing separate subgroups of treatment-naive motor neuropathies, including multifocal CIDP (synonyms: multifocal demyelinating neuropathy with persistent conduction block), which differs from multifocal motor neuropathy with conduction block (MMN) in both responses to treatment modalities and electrophysiological features. Ultrasound is a reliable method for diagnosing immune-mediated neuropathies, particularly when alternative diagnostic examinations yield inconclusive results. In overall terms, the management of these disorders includes immunotherapy such as corticosteroids, intravenous immunoglobulin or plasma exchange. Improvements in clinical criteria and the development of more disease-specific immunotherapies should expand the therapeutic possibilities for these debilitating diseases.

Vocational activity for patients with multiple sclerosis.

INTRODUCTION: Multiple sclerosis (MS) usually occurs in young adults and, due to its long-lasting course and variety of symptoms, can affect their vocational activity. Our study aimed to evaluate employment status and working activity for persons with MS with regard to disease-related factors, quality of life, and depression. MATERIAL AND METHODS: 250 subjects with MS (62 men, 188 women, aged 19-71 years, mean 42.2) responded to a survey into various aspects of their employment. Relationships were sought between work-related issues and disease-related variables [MS type and duration, major symptoms, disability level on the Expanded Disability Status Scale (EDSS)], quality of life (WHOQOL- -BREF, World Health Organisation Quality of Life brief questionnaire) and depression (BDI, Beck Depression Inventory). Statistical analysis included Mann-Whitney U, Student's t, and Pearson's chi-squared tests. RESULTS: 71.2% of the patients were employed, and 49.1% perceived an impact of the disease upon their working activity (i.e. job loss, problems with finding a new one, and/or forced change of type and/or character of employment). Unemployed subjects had higher EDSS scores (4.05 vs. 2.34, p < 0.001) and longer disease durations (13.6 vs. 9.4, p < 0.001) than employed ones. They also scored higher on BDI (15.4 vs. 9.05, p < 0.001) and lower in all domains of WHOQOL-BREF (p < 0.001). CONCLUSIONS: The consequences of MS negatively influence many work-related factors. Unemployment is associated with a higher frequency of depression and a lower quality of life in MS patients.

Pathology of Initial Axon Segments in Chronic Inflammatory Demyelinating Polyradiculoneuropathy and Related Disorders.

The diagnosis of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is based on a combination of clinical, electrodiagnostic and laboratory features. The different entities of the disease include chronic immune sensory polyradiculopathy (CISP) and autoimmune nodopathies. It is debatable whether CIDP occurring in the course of other conditions, i.e., monoclonal IgG or IgA gammopathy, should be treated as a separate disease entity from idiopathic CIDP. This study aims to evaluate the molecular differences of the nodes of Ranvier and the initial axon segment (AIS) and juxtaparanode region (JXP) as the potential cause of phenotypic variation of CIDP while also seeking new pathomechanisms since JXP is sequestered behind the paranode and autoantibodies may not access the site easily. The authors initially present the structure of the different parts of the neuron and its functional significance, then discuss the problem of whether damage to the juxtaparanodal region, Schwann cells and axons could cause CIDP or if these damages should be separated as separate disease entities. In particular, AIS's importance for modulating neural excitability and carrying out transport along the axon is highlighted. The disclosure of specific pathomechanisms, including novel target antigens, in the heterogeneous CIDP syndrome is important for diagnosing and treating these patients.

Allostatic load index in patients with multiple sclerosis: A case-control study.

Elevated allostatic load (AL) index is a cumulative measure of biological dysregulations associated with stress exposure. It has been reported that stress plays an important role in the pathophysiology of multiple sclerosis (MS). However, the AL index has not been investigated in this population so far. Therefore, we aimed to investigate the AL index in patients with MS compared to healthy controls. A total of 90 patients with relapsing-remitting MS (76.7% females) and 47 healthy controls (76.6% females) were included in the study. The AL index was computed based on percentile distributions of 18 biomarkers. The AL index was significantly higher in patients with MS compared to healthy controls (2.74 ± 0.99 vs. 1.96 ± 0.71, p < 0.001), even after adjustment for age and education. With respect to specific AL biomarkers, individuals with MS had significantly lower resting heart rate, the levels of high-density lipoproteins and dehydroepiandrosterone sulfate as well as significantly higher level of hsCRP and albumin compared to healthy controls. There were no significant correlations of the AL index with depressive and anxiety symptoms, perceived stress, type D personality traits, insomnia, the odds of using specific coping strategies as well as MS-related clinical characteristics. These findings indicate that the AL index is increased in patients with MS. However, the exact mechanisms underlying this observation remain unknown and require additional studies.

The Level of Stress and Coping Strategies in Patients with Multiple Sclerosis and Their Relationships with the Disease Course.

OBJECTIVES: Stress is supposed to be linked with a background of multiple sclerosis (MS) and the disease course. DESIGN: The study aimed to assess the level of stress and coping strategies in MS patients within a year of follow-up and to investigate the relationships between these aspects and factors related-or not-to MS. METHODS: In 65 patients with MS, the Perceived Stress Scale (PSS-10), Type D Scale (DS14) and Coping Orientations to Problems Experienced (COPE) were performed at baseline and after a year. Baseline PSS-10, DS-14 and COPE scores were analyzed with regard to demographics, MS duration, treatment, indices of disability and self-reported stressful events (SEs). Final PSS-10 and COPE results were analyzed with reference to MS activity and SE within a year of follow-up. RESULTS: Initially, 67% of patients reported a moderate or high level of stress and 31% met Type-D personality criteria. Diverse coping strategies were preferred, most of which were problem-focused. The negative affectivity DS-14 subscore (NEG) was correlated with disability level. Non-health-related SEs were associated with higher PSS-10 and NEG scores. After a year, the mean PSS-10 score decreased, while COPE results did not change significantly. Non-health-related SEs were associated with a higher PSS-10 score and less frequent use of acceptance and humor strategies. Those with an active vs. stable MS course during the follow-up did not differ in terms of PSS-10 and COPE results. CONCLUSIONS: MS patients experienced an increased level of stress. No significant relationships were found between stress or coping and MS course within a year. Non-health-related factors affected measures of stress more than MS-related factors.

What can we learn from the online learning experiences of medical students in Poland during the SARS-CoV-2 pandemic?

BACKGROUND: In March 2020, due to the SARS-CoV-2 pandemic, the Polish government ordered the closing of all medical faculties, with an obligatory shift to online learning. This lockdown continued, with a short period of blended learning, over the time of summer 2020. Distance learning had previously been rarely used within Polish medical schools, so such a sudden transfer was a major challenge. The aim of the study was to explore undergraduates' perception of online teaching provided at Polish medical faculties during the pandemic and to analyze how these experiences may inform future curriculum development. METHODS: The online survey was addressed to undergraduates at Polish medical faculties in November 2020. The questions captured demographics, epidemiological data and students' perception of various aspects of online teaching. Responses were subjected to thematic analysis and their distribution compared considering demographic parameters . RESULTS: Six hundred twenty students from thirteen medical faculties responded to the survey. Major benefits from online teaching perceived by respondents included increased convenience, enhanced quality, a sense of comfort and safety. Major complaints were associated with unsatisfactory content, technical issues, difficulties engaging, poor organization and lack of social life. Students claimed that online teaching required more self-directed learning and discipline and 57.9% considered this impact as negative. 44.5% of respondents took part in educational online activities beyond their scheduled classes. For 49.2% online examinations were reported as more stressful and for 24.8% - less stressful than traditional ones. Differences in the opinions on online teaching were found between men and women, students in early and senior years, Polish and non-Polish ones. CONCLUSIONS: The sudden move online inevitably was problematic for students. Their perspective afforded us the opportunity to consider shortcomings of pre-pandemic undergraduate curriculum. Online education requires a more self-directed learning, which was challenging for many students, so further enhancement of more autonomous study skills seems necessary. Distress expressed by students indicates the need for urgent support with mental health issues.

Pre-Stroke Statin Therapy Improves In-Hospital Prognosis Following Acute Ischemic Stroke Associated with Well-Controlled Nonvalvular Atrial Fibrillation.

Many studies have confirmed the positive effect of statins in the secondary prevention of ischemic stroke. Although several studies have concluded that statins may also be beneficial in patients with atrial fibrillation-related stroke, the results of those studies are inconclusive. Therefore, the aim of this study was to analyze the effect of pre-stroke statin therapy on atrial fibrillation-related stroke among patients with a well-controlled atrial fibrillation. This retrospective multicenter analysis comprised 2309 patients with acute stroke, with a total of 533 patients meeting the inclusion criteria. The results showed a significantly lower neurological deficit on the National Institutes of Health Stroke Scale at hospital admission and discharge in the group of atrial fibrillation-related stroke patients who took statins before hospitalization compared with those who did not (p < 0.001). In addition, in-hospital mortality was significantly higher in the atrial fibrillation-related stroke patients not taking statins before hospitalization than in those who did (p < 0.001). Based on the results of our previous research and this current study, we postulate that the addition of a statin to the oral anticoagulants may be helpful in the primary prevention of atrial fibrillation-related stroke.

Migraine and Sleep-An Unexplained Association?

Migraine and sleep disorders are common chronic diseases in the general population, with significant negative social and economic impacts. The association between both of these phenomena has been observed by clinicians for years and is confirmed by many epidemiological studies. Despite this, the nature of this relationship is still not fully understood. In recent years, there has been rapid progress in understanding the common anatomical structures of and pathogenetic mechanism between sleep and migraine. Based on a literature review, the authors present the current view on this topic as well as ongoing research in this field, with reference to the key points of the biochemical and neurophysiological processes responsible for both these disorders. In the future, a better understanding of these mechanisms will significantly expand the range of treatment options.

Ischemic Stroke Risk Factors in Patients with Atrial Fibrillation Treated with New Oral Anticoagulants.

The most commonly used therapeutic option for the prevention of ischemic stroke in patients with atrial fibrillation is new- or old-generation oral anticoagulants. New oral anticoagulants are at least as effective as old-generation oral anticoagulants in the prevention of ischemic stroke, with a reduced risk of life-threatening hemorrhage. Moreover, the constant monitoring of these drugs in the patient's blood is not required during routine use. However, ischemic stroke can still occur in these patients. Therefore, the aim of this study was to investigate the pattern of risk factors for ischemic stroke in patients with atrial fibrillation treated with new oral anticoagulants. Our multicenter retrospective study involved 2032 patients with acute ischemic stroke. The experimental group consisted of 256 patients with acute ischemic stroke and nonvalvular atrial fibrillation, who were treated with new oral anticoagulants. The control group consisted of 1776 ischemic stroke patients without coexisting atrial fibrillation. The results of our study show that patients with atrial fibrillation treated with new oral anticoagulants are more likely to display thrombotic, proatherogenic, and proinflammatory factors in addition to the embolic factors associated with atrial fibrillation. Therefore, solely taking new oral anticoagulants is insufficient in protecting this group of patients from ischemic stroke.

Pathophysiology of the Different Clinical Phenotypes of Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP).

Chronic inflammatory demyelinating polyneuropathy (CIDP) is the most common form of autoimmune polyneuropathy. It is a chronic disease and may be monophasic, progressive or recurrent with exacerbations and incomplete remissions, causing accumulating disability. In recent years, there has been rapid progress in understanding the background of CIDP, which allowed us to distinguish specific phenotypes of this disease. This in turn allowed us to better understand the mechanism of response or non-response to various forms of therapy. On the basis of a review of the relevant literature, the authors present the current state of knowledge concerning the pathophysiology of the different clinical phenotypes of CIDP as well as ongoing research in this field, with reference to key points of immune-mediated processes involved in the background of CIDP.

Risk of Short-Term Mortality after Intracerebral Haemorrhage due to Weekend Hospital Admission in Poland.

BACKGROUND: The mortality rate for spontaneous intracerebral haemorrhage (ICH) has remained high and stable for many years. The unfavourable prognostic factors include age, bleeding volume, location of the haematoma, high blood pressure, and disturbed consciousness on admission. Other risk factors associated with medical care also deserve attention. The study aimed to analyse the relationship between day of admission, concerning other prognostic factors, and short-term mortality in ICH, in a Polish specialist stroke unit. METHODS: Medical records of 156 patients (74 males, 82 females, mean age 68.7 years) diagnosed with spontaneous ICH and admitted to a specialist stroke center were retrospectively analysed. Demographics, location, volume of bleeding, blood pressure values, and the Glasgow Coma Scale (GCS), as well as the day of admission, were determined. The relationships were analysed between these factors and 30-day mortality in the patients with ICH. RESULTS: A total of 83 patients were admitted to the hospital during weekdays (Monday 8 am to Friday 3 pm) and 73 during weekends or holidays. Of these, 65 patients died within 30 days. Patients admitted at weekends initially presented with lower GCS scores. Admission on Saturday was associated with an increased risk of death (OR 3.38, 95% CI 1.2-9.48, p < 0.05), but after correction for clinical state measured with the GCS and ICH score, the association was no longer significant. CONCLUSIONS: The time and mode of admission were not associated with increased risk of short-term mortality in ICH patients. Prehospital care issues should be additionally considered as prognostic factors of the outcome.

Transient Global Amnesia - Risk Factors and Putative Background.

OBJECTIVES: Transient global amnesia (TGA) is a temporary short-term reversible memory loss. Etiology of TGA remains unclear with various hypotheses. We analyzed clinical characteristics, neuroimaging, and electrophysiological findings as well as comorbidities and seasonal variation in TGA patients with regard to possible background of the syndrome. MATERIALS AND METHODS: A total of 56 patients (42 women and 14 men) with TGA hospitalized from 2008 to 2016 in the Department of Neurology, Wroclaw Medical University. RESULTS: A total of 52 patients (92.9%) underwent their first-ever episode of TGA. The potential triggers or events before episode could be recognized in 22 patients (39.3%). 35.7% patients had TGA in summer and 26.8% in winter months. In 92.9% patients chronic diseases were found, included: Hypertension (60.7%), dyslipidemia (48.2%), autoimmune thyroiditis (17.9%), and ischemic heart disease (14.3%). One patient (1,8%) suffered from migraine. Doppler ultrasonography of carotid arteries revealed abnormalities in 29 patients (51.8%). Electroencephalography abnormalities were observed in 10 (17.6%) of patients. CONCLUSION: Our findings suggest a putative cerebrovascular background of transient global amnesia. No evidence has been provided for the association between TGA and epilepsy or migraine. Among comorbidities, autoimmune thyroiditis deserves further investigation with regard to its potential links with TGA.

Mental disorders in patients with epilepsy. / Zaburzenia psychiczne u chorych na padaczke.

Mental disorders occur in patients with epilepsy significantly more frequently than in the general population or in those with other chronic diseases. The specificity of epilepsy as a condition of the central nervous system with complex somatic, psychic and social consequences contributes to co-occurrence of these disorders. Moreover, common patomechanisms are suggested for epilepsy and mental disorders, associated with disturbances of bioelectrical activity and neurotransmission in certain areas of the brain.The authors present a review of main groups of mental disorders observed in epileptic patients: psychotic, affective, anxiety, personality, and conduct disorders. They discuss their epidemiology and clinical presentation, with a particular focus on their risk factors and temporal relation to epileptic seizures. They also highlight problems associated with differential diagnosis and optimal therapeutic strategy. Mental disorders have a significant impact on the quality of life and functioning of patients with epilepsy. Further exploration of interrelationships between these illnesses, as well as cooperation between neurologists and psychiatrists promote an early and precise diagnosis of mental disturbances in this group of patients and their effective treatment.

Social participation of patients with multiple sclerosis.

BACKGROUND: The effect multiple sclerosis (MS) has on the social functioning and integration of patients has been recently considered as an important factor of the disease. OBJECTIVES: To assess social participation of MS patients with regard to demographic and disease-related variables. MATERIAL AND METHODS: The study comprised 201 MS patients: 140 women, 61 men, aged 24-69 years. The World Health Organization Disability Assessment Schedule (WHODAS 2.0) was applied to assess the aspects of social functioning and the Beck Depression Inventory (BDI) was applied to evaluate the level of depression. Disease duration, degree of disability in Expanded Disability Status Scale (EDSS), most disabling symptoms and type of treatment were determined. WHODAS 2.0 scores (total and within particular domains) and their relationships with age, gender, disease-related variables and level of depression were analyzed. RESULTS: The results of WHODAS 2.0 for 27.4% of patients exceeded the 90th percentile compared to the population norms (with the highest scores for "getting around" and "participation in society" domains). The results of BDI and WHODAS 2.0 were strongly correlated (p < 0.001; ß = 0.73) and mobility impairment was related to both of them (p < 0.001; ß = -0.12 and 0.25, respectively). Other disabling symptoms were associated with scores in domains "understanding and communicating", "getting around" and "participation in society". CONCLUSIONS: Social participation of the MS patients is affected by the impact of disease and associated with depression. Particular symptoms of neurological deficit (motor and visual impairment, fatigue) influence social functioning more than general disease-related variables.

Management of bleeding in patients hospitalized in the intensive cardiac care unit: expert opinion of the Association of Intensive Cardiac Care and Section of Cardiovascular Pharmacotherapy of the Polish Cardiac Society in cooperation with specialists in other fields of medicine.

Nowadays, the intensive cardiac care unit (ICCU) provides care for patients with acute coronary syndrome, acute and exacerbated chronic heart failure, cardiogenic shock, sudden cardiac arrest, electrical storm, as well as with indications for urgent cardiac surgical treatment. Most of these patients require the use of 1, 2, or frequently even 3 drugs that act on the blood coagulation pathway. While antithrombotic drugs prevent thromboembolic events, they are associated with a higher risk of bleeding. In this population of patients, bleeding may often have a worse impact on prognosis than the primary disease. In this expert opinion of the Association of Intensive Cardiac Care, we presented practical guidelines on the management of bleeding in patients hospitalized at the ICCU, including bleeding risk reduction and treatment recommendations. Because of multiple comorbidities and diverse organs that may be the source of bleeding, we provided also recommendations from specialists in other fields of medicine. We hope that this document will facilitate the management of one of the most challenging populations at the ICCU.

The relationship between event-related potentials, stress perception and personality type in patients with multiple sclerosis without cognitive impairment: A pilot study.

BACKGROUND: The clinical course of multiple sclerosis (MS) can vary significantly among patients and is affected by exogenous and endogenous factors. Among these, stress and personality type have been gaining more attention. OBJECTIVES: The aim of this study was to investigate the parameters of event-related potentials (ERPs) with regards to stress perception and personality type, as well as cognitive performance in MS patients. MATERIAL AND METHODS: The study group consisted of 30 MS patients and 26 healthy controls. Auditory ERPs were performed in both groups, including an analysis of P300 and N200 response parameters. The Perceived Stress Scale (PSS) was used in the MS group to measure the perception of stress. The D-type Scale (DS14) scale was used to determine the features of Type D personality, characterized by social inhibition and negative affectivity. RESULTS: The score on the PSS corresponded with a moderate or high level of stress perception in 63% of MS patients, while 23% of patients presented with a Type D personality. P300 latencies were significantly longer (p = 0.001), N200 amplitudes were significantly higher (p = 0.004), and N200 latencies were longer in MS patients than in the controls. Strong positive correlations were found between N200 and P300 amplitudes, as well as between the DS14 and PSS results. CONCLUSIONS: Most MS patients experience moderate to severe stress. ERP abnormalities were found in MS patients who did not have overt cognitive impairment and showed correlations with stress levels and negative affectivity. Event-related potentials may be useful in assessing the influence of stress and emotions on the course of MS.

Mathematical models of human cerebellar development in the fetal period.

The evaluation of cerebellar growth in the fetal period forms a part of a widely used examination to identify any features of abnormalities in early stages of human development. It is well known that the development of anatomical structures, including the cerebellum, does not always follow a linear model of growth. The aim of the study was to analyse a variety of mathematical models of human cerebellar development in fetal life to determine their adequacy. The study comprised 101 fetuses (48 males and 53 females) between the 15th and 28th weeks of fetal life. The cerebellum was exposed and measurements of the vermis and hemispheres were performed, together with statistical analyses. The mathematical model parameters of fetal growth were assessed for crown-rump length (CRL) increases, transverse cerebellar diameter and ventrodorsal dimensions of the cerebellar vermis in the transverse plane, and rostrocaudal dimensions of the cerebellar vermis and hemispheres in the frontal plane. A variety of mathematical models were applied, including linear and non-linear functions. Taking into consideration the variance between models and measurements, as well as correlation parameters, the exponential and Gompertz models proved to be the most suitable for modelling cerebellar growth in the second and third trimesters of pregnancy. However, the linear model gave a satisfactory approximation of cerebellar growth, especially in older fetuses. The proposed models of fetal cerebellar growth constructed on the basis of anatomical examination and objective mathematical calculations could be useful in the estimation of fetal development.

Persistent genital arousal disorder - a case report. / Zespól uporczywego pobudzenia genitaliów ­ opis przypadku.

The persistent genital arousal disorder (PGAD) may coexist with restless legs syndrome and overactive bladder syndrome and share some similarities with these conditions. Thus, the new term: restless genital syndrome (RGS) is proposed. The purpose of this paper is to present a case of PGAD, including the description of the etiology, the diagnostics and the treatment of the disorder. The described patient meets the criteria for PGAD. Organic lesions within nervous and urogenital system were excluded and the psychogenic background of the syndrome was assumed in this case. The patient was diagnosed with personality disorder with a predominance of dependent personality traits and emotional lability. After the failure of pharmacological treatment, systemic psychotherapy with cognitive-behavioral elements was initiated with moderate effect.
