NUMERICAL STUDY OF THE EFFECT OF WALL THICKNESS AND INTERNAL PRESSURE ON VON MISES STRESS AND SAFETY FACTOR OF THIN-WALLED CYLINDER FOR ROCKET MOTOR CASE
Authors: Wibawa Lasinta Ari Nendra
Published: June 2020

The rocket motor is an important part of rockets. The rocket motor works using the pressure vessel principle because it works in an environment with high pressure and temperature. This paper investigates the von Mises stress that occurs in thin-walled cylinders and safety factors for rocket motor cases due to the influence of the wall thickness and internal pressure. Dimensions of the cylinder length are 500 mm, outer diameter is 200 mm, and cap thickness is 30 mm. The wall thickness is varied 6, 7, 8, and 9 mm, while the internal pressure is varied 8, 9, and 10 MPa. Stress analysis is performed using the finite element method with Ansys Workbench 2019 R3 software. The simulation results show that the maximum von Mises stress decreases with increasing wall thickness. The maximum von Mises stress increases with increasing internal pressure. The material has a safety factor higher than 1.25 for all variations in wall thickness and internal pressure. It means that the material can withstand static loads. The verification process is done by comparing the results of finite element analysis with analytical calculations for maximum hoop stress and maximum axial stress with a fixed boundary condition. The results of maximum hoop stress and maximum axial stress using finite element analysis and analytical calculations are not significantly different. The percentage of errors between analytical calculations and finite element analysis is less than 6 percent.

Authors: Raitio Katja , Siitonen Marko , Hopia Hanna
Published: June 2020

This study analyses the application of a co-production approach in utilizing digital games and game-related methods in mental health services. The goal is to offer a real-world experiment on co-production, focusing on mental health service users, active gamers and mental health practitioners who worked together in equal ways and valued each other’s unique contributions during the experiment. The implications of a co-production approach for applying digital games in the field of mental healthcare are somewhat limited and under-explored. In this case study, seven workshop sessions were held involving service users, gamers and professionals. Participants were interviewed concerning their experiences with the activities and content of the co-production workshops. Thematic analysis of the participants’ experiences and perceptions resulted in three main themes: 1) empowering participation; 2) cooperation on a level playing field; and 3) improving self-efficacy. The experiment showed that applying a co-production approach in utilizing digital games is worth implementing in mental health services, particularly when putting novel nursing approaches and procedures into practice. Overall, co-production turned out to be a beneficial approach to introduce and implement game activities into mental healthcare; therefore, it can be taken one step further, meaning that service users’ experiences are truly valued, and they can play a crucial role in developing mental health services.
Выделение ключевых компонент технологии блокчейн на основе анализа ряда реализаций
Authors: Сазонова Полина
Published: June 2020

Технология блокчейн была впервые реализована в 2008 году, и за последние 12 лет в индустрии появилось более 2000 различных ее реализаций. Исследователи в мире рассматривают данную технологию либо в прикладном аспекте, либо улучшая ее отдельные компоненты. Такой фрагментарный подход приводит индустрию к проблеме отсутствия общей картины, что приводит к невозможности определения реальной ценности новой разработки и, как следствие, замедлению развития технологии. Целью данной работы является выделение ключевых компонент внутреннего устройства технологии блокчейн и предложение ее универсальной модели. На основе технического анализа наиболее популярных блокчейнов были выделены компоненты, присутствующие у всех блокчейнов и определена их роль при решении тех задач, для которых данный блокчейн разрабатывался. Результаты данной работы могут быть использованы архитекторами новых блокчейн-сетей для достижения целей их разработки.
Entre lo inesperado y lo imprevisto: la sequía y los proyectos de mejoramiento de maíz y sorgo en El Bajío, 1943-1970
Authors: Gutiérrez Núñez Netzahualcóyotl Luis
Published: June 2020

El presente artículo estudia la relación entre los proyectos de mejoramiento del maíz y el sorgo, en el marco de la revolución verde, y su relación con las condiciones medioambientales a mediados del siglo pasado. Como resultado de los periodos de sequía que se experimentaron en las décadas de 1940 y 1950 en el centro y norte de México, los rendimientos de las plantas creadas en la Oficina de Estudios Especiales tuvieron rendimientos por debajo de las expectativas. Sin embargo, el sorgo, una planta de origen africano que había tenido éxito en áreas agrícolas estadounidenses susceptibles a la sequía, se adaptó de manera rápida a las condiciones climáticas y agrológicas del Bajío, integrándose a la emergente industria forrajera y a la incipiente ganadería porcina. El sorgo representó así una solución binacional a problemas compartidos, pero también un forraje fundamental para la expansión de la actividad ganadera que coadyuvó en la transición alimentaria mexicana hacia dietas con un mayor contenido de proteína.

Chronic Kidney Disease: Clinical Characteristics and psychosocial aspects
Authors: Fradelos Evangelos , Mitsi Dimitroula , Zyga Sofia
Published: June 2020

Chronic kidney disease is characterized by persistent renal impairment and/or loss of renal function. This condition is associated with high morbidity and mortality, and despite progress in prevention, diagnosis and treatment, CKD remains an important public health problem. Emotional discomfort, manifested by symptoms of anxiety and depression, is common in chronic illnesses with incidence/prevalence rates and the severity of symptoms being significantly higher among patients with chronic health problems such as heart disease, rheumatoid arthritis or chronic renal disease, compared to the general population. While the estimate accuracy may vary due to methodological differences and differences in measurements between studies, there are indications that chronic disease with coexisting depression is associated with increased symptom burden and functional impairment, poor quality of life, non-observance of treatment and worse clinical outcomes. Psychosocial issues among these patient groups are important not only for maintaining a good quality of life, but also for managing the disease. As mental health is a predictive factor for the outcomes of CKD patients, the management of any issues that arise is of paramount importance. The role of nephrology nurses is particularly important both in the implementation of nursing interventions related to the treatment and management of the disease, as well as in the provision of individualized psychological support to patients undergoing hemodialysis.

El espacio simbólico en el antiguo convento de la Magdalena de Antequera (Málaga)
Authors: Vázquez Sánchez José Antonio
Published: June 2020

El antiguo convento de santa María Magdalena de Antequera (Málaga), perteneciente a la Orden de los Hermanos menores de la estricta observancia o franciscanos descalzos alcantarinos, constituye uno de los mejores ejemplos de la religiosidad anacoreta del barroco andaluz, profusamente decorado con pinturas al temple, configurando un espacio simbólico conventual basado en las doctrinas del fundador de la Orden, san Pedro de Alcántara y reflejadas en su libro Tratado de Oración y Meditación (1587).  Esta obra constituye una de las joyas de la mística española, cuya función era ayudar a cualquier persona que quisiera conseguir la unión del alma con Dios mediante la purificación de sus vicios y sus pecados, con unas reglas estrictas de pobreza absoluta, descalcez, retiro para la oración y abandono total en manos de la Providencia Divina y el ministerio de la predicación.
Los cofrades de las hermandades de Jesús el nazareno en el reino de Murcia a mediados del siglo XVII
Authors: Maestre de San Juan Pelegrín Federico , Montojo Montojo Vicente
Published: June 2020

La investigación sobre los componentes de las hermandades de Jesús Nazareno de Cartagena y Murcia ha permitido comprobar que hasta casi finales del XVII fueron artesanos y desde finales del mismo fueron comerciantes y mercaderes, además de artesanos, o ya en el XVIII se añadieron nobles. Tal evolución se manifestó en que, en una primera época, los logros artísticos de los artesanos fueron escasos, mientras que la incorporación de mercaderes y comerciantes originó que se ampliaran y ornamentaran capillas e incluso se incorporaran imágenes valiosas, pero los mayores logros se obtuvieron a mediados del XVIII, con la incorporación de retablos y esculturas o pasos de conjuntos de imágenes, entre los que destacaron los del escultor Francisco Salzillo.

Methodological approaches to accounting for financial instruments: Current issues and advisable solutions
Authors: Druzhilovskaya T.Yu. , Dobrolyubov N.A.
Published: June 2020

Subject. The article discusses the way financial instruments are accounted for, and related issues.
Objectives. We outline our recommendations to address problems concerning the financial instruments accounting technique.
Methods. The study involves a critical analysis, synthesis, comparison, observation, analogies.
Results. We prove the inadequacy of the regulatory framework for accounting for financial instruments of the Russian non-credit institutions. As discussed in the scientific literature on accounting for financial instruments, advisable methodological approaches were found to vary significantly. We justify our recommendations on addressing challenging issues of accounting for non-derivative and derivative financial instruments and provide our suggestions on accounting for financial assets qualified as cash equivalents, advice on separate accounting and recognition of financial liabilities, recognition of financial derivatives in accounts.
Conclusions and Relevance. Currently, Russia's regulations govern only some issues of accounting for financial instruments. There are plenty of accounting aspects concerning derivative and non-derivative financial instruments that remain unregulated. As proposed in the scientific literature on accounting for financial instruments, methodological approaches significantly differ. International standards do not exhaustively govern complicated issues of accounting for financial instruments. Thus, research on accounting for financial instruments should continue. It is important to promote the regulatory framework for financial instruments accounting as long as a set of the Russian accounting standards are revised. The findings are of applied and theoretical nature for financial accounting.

Published: June 2020

Subject. This article considers the industry structure of the economy as a system susceptible to rapid quantitative and qualitative changes.
Objectives. The article aims to comprehensively study shifts and changes in the sectoral and regional structures of the Russian industry.
Methods. For the study, we used the methods of theoretical differentiation and insight of the object, sequential clustering, analytical population, grouping of data on an adjacent basis, and conceptual algorithmization.
Results. The article highlights structural changes in the Russian industry, significant disparities in the types of economic activity under study in terms of regions, positive shifts, growth zones, and prospective regions for investment. Positive trends need to be promoted.
Conclusions. The Russian industrial policy traditionally gravitates towards a vertical model and the preferential use of budgetary and quasi-budget financing tools. The consequence of this situation is the excessive fragmentation of the policy. Taking into account the variety of cases of the industrial policy implementation in Russia, the success achieved can be considered relatively local.

Pelaksanaan Tugas Fungsi dan Kewenangan Kejaksaan Republik Indonesia dalam Hubungannya dengan Sistem Ketatanegaraan di Indonesia Menurut Undang Undang Nomor 16 Tahun 2004
Authors: Sanusi  , Pradini Imso Lorent
Published: June 2020

Jaksa adalah pegawai pemerintah yang berkecimpung di bidang hukum, bertugas menyampaikan dakwaan atau tuduhan didalam proses pengadilan terhadap orang yang diduga melanggar hukum. Dalam bahasa Belanda disebut officer van justitie, dalam bahasa inggris disebut public prosecutor. jaksa sebagai salah satu penegak hukum mempunyai tanggungjawab untuk menjalankan strategi pembangunan hukum yang telah dijamin dalam undang– undang. Undang Undang Nomor 16 Tahun 2004 tentang Kejaksaan Republik Indonesia telah menjamin kemandirian kejaksaan dalam melaksanakan tugasnya, sesuai yang tercantum dalam pasal 2 ayat (2). Akan tetapi dalam ketentuan selanjutnya kedudukan kejaksaan tidak dapat terlepas dari lembaga eksekutif. Sehingga dalam pelaksanaan tugasnya kejaksaan seringkali dihadapkan pada persoalan kemandirian dalm pencapaian tugas, karena bagaimanapun kejaksaan tidak dapat melepaskan diri dari bayang-bayang lembaga eksekutif, hal inilah yang menyebabkan kejaksaan sering dianggap tidak profesional. Menghindari dominasi tunggal Presiden dalam menentukan jabatan Jaksa Agung, maka harus dilakukan dengan melibatkan lembaga lain seperti DPR atas persetujuan dari seluruh rakyat. Menyadari bahwa kekuasaan penuntutan merupakan bagian dari kekuasaan kehakiman, maka pengertian kekuasaan kehakiman yang dijabarkan dalam UUD 1945 hasil amandemen perlu ditinjau kembali. Keterpaduan dalam kekuasaan kehakiman dapat memberikan pengaruh dan kontrol satu sama lain. Maka dari itu sangat diperlukan untuk meletakkan kekuasaan penyelidikan dan penuntutan dalam bab kekuasaan kehakiman didalam UUD 1945 apabila di kemudian hari dilakukan amandemen kelima.
Implikasi Hukum Terhadap Pembatasan Peran Serta Aparatur Sipil Negara dalam Proses Politik di Indonesia
Authors: Haryadi Toni , Praptono Eddhie , Aditya Pratama Erwin
Published: June 2020

Secara konstitusional, salah satu bentuk penerapan hak politik tercermin dalam hak untuk bebas berserikat, berkumpul dan mengeluarkan pikiran.Hak tersebut merupakan indikator bahwa suatu negara telah melaksanakan demokrasi. Secara umum, makna netralitas yang dimaksudkan adalah bebasnya Aparatur Sipil Negara dari pengaruh kepentingan partai politik tertentu atau tidak memihak untuk kepentingan partai tertentu atau tidak berperan dalam proses politik. Hal ini memberikan makna bahwa Aparatur Sipil Negara sama sekali tidak boleh masuk dalam ranah politik. Namun pada sisi lainnya, Aparatur Sipil Negara masih tetap mempunyai hak politik untuk memilih dan berhak untuk dipilih dalam proses politik, namun tidak diperkenankan aktif menjadi anggota dan pengurus partai politik. Tujuan penelitian kali ini adalah melihat sejauh mana peran yang dapat dilaksanakan aparatur sipil negara dalam proses politik di Indonesia. Metode penelitian ini menggunakan penelitian normati. Pengumpulan data memanfaatkan kepustakaan. Dan pengolahan data dilaksanakan secara kualitatif. Implikasi hukum terhadap pembatasan peran serta Aparatur Sipil Negara dalam proses politik, berupa Pertama, implikasi hukum terhadap inkonsistensi pengaturan tentang netralitas yang meliputi terdapatnya aturan yang menimbulkan celah hukum, sehingga dapat digunakan oleh Aparatur Sipil Negara untuk berperan serta aktif dalam proses politik, terjadinya pengaburan makna netralitas dan terciptanya ambiguitas regulasi; Kedua, implikasi hukum terhadap pelanggaran ketentuan tentang pembatasan peran serta Aparatur Sipil Negara dalam proses politik menciptakan sanksi administratif yang didasarkan pada berat ringannya jenis pelanggaran yang dilakukan oleh oknum Aparatur Sipil Negara.
Kajian Hukum Terhadap Penerapan Eksekusi Hukuman Kebiri Bagi Pelaku Kekerasan Seksual Terhadap Anak
Authors: Defi Muslimah Defi Muslimah , Siswanto
Published: June 2020

Perubahan kedua Undang-undang Nomor 23 tentang Perlindungan Anak menjadi Undang-undang Nomor 17 tahun 2016 merupakan trobosan baru yang dilakukan pemerintah sebagai upaya untuk meminimalisir terjadinya kekerasan seksual terhadap anak. Trobosan tersebut tertuang dalam pasal 7 yang memberlakukan hukuman tambahan berupa hukuman kebiri kimia dan pemasangan alat penditeksi elektronik bagi pelaku kekerasan seksual. Ketentuan pasal 7 terkait dengan hukuman kebiri akhirnya berlaku dan diterapkan untuk pertama kalinya oleh putusan hakim Pengadilan Mojokerto. Rumusan masalah pada penelitian ini adalah mengenai kerelevansi undang-undang Nomor 16 tahun 2017 tentang sebagai perubahan kedua atas Undang-undang Nomor 23 tahun 2002 tentang perlindungan anak yang berbenturan dengan Hak Asasi Manusia Kesehatan dan bagaimana kerelevansi pelaksanaan eksekusi terhadap hukuman kebiri tanpa adanya petunjuk pelaksanaannya. Penelitian ini menggunakan focus judicial case study. Jenis Penelitian yang digunakan adalah penelitian kepustakaan. Pendekatan dilakukan adalah dengan menggunakan pendekatan normative. Jenis data yang digunakan meruapakan data sekunder. Sumber data penelitian diperoleh dari bahan hukum sekunder. Metode pengolahan data menggunakan Penelusuran kepustakaan. Metode analisis data dilakukan dengan metode kualitatif. Hasil penelitian menunjukan, bahwa diberlakukannya hukuman kebiri tidak serta merta dapat meminimalisir adanya kekerasan seksual terhadap anak. Hukuman pada dasarnya melanggar hak asasi manusia, tetapi harus tetap dilakukan dengan manusiawi. Perbuatan kejahatan kekerasan seksual terhadap anak merupakan perbuatan yang mucul dari adanya keinginan untuk memuaskan hasrat seksual, meskipun dengan diberlakukan hukuman kebiri tidak bisa memutus keinginan untuk melakukan hal tersebut. Pemberian hukuman kebiri terhadap pelaku tidak akan memberikan efek jera bagi pelaku, hukuman mati merupakan hukuman yang pantas untuk didapatkannya. Kepastian hukum menjadi salah satu tujuan dari hukum, berdasarkan asas legalitas segala sesuatu tentu harus dilakukan dan dilaksanakan berdasarkan ketentuan yang ada, belum adanya petunjuk pelaksanaan dan teknis dalam hukuman kebiri menjadikan asas legalitas hanya berlaku bagi sebuah bunyi pasal yang menyatakan suatu jenis kejahatan, pelanggaran dan hukumannya tanpa adanya petunjuk pelaksanaan dalam menerapakan hukuman.
Analisis Normatif Terhadap Putusan Praperadilan No. 04/PID.PRAP/2015/PN. Berdasarkan Prespektif Kemanfaatan, Kepastian Hukum dan Keadilan
Authors: Mukharom  , Indah Astanti Dhian , Tuti Muryati Dewi
Published: June 2020

Tujuan hukum menurut Gustav Radbruch yaitu keadilan, kepastian, dan kemanfaatan, tujuan ini menjadi tolak ukur penulisan dalam mengkaji putusan praperadilan. Salah satu Putusan Praperadilan yang dianggap kontroversial adalah Putusan No. 04/Pid.Prap./2015/PN.Jaksel tanggal 16 Februari 2015 yang diajukan oleh Pemohon Kom.Jen Polisi Drs. Budi Gunawan melawan Komisi Pemberantasan Korupsi (KPK) yang telah menetapkan Pemohon sebagai tersangka tindak pidana korupsi. Hakim tunggal Sarpin Rizaldi dalam perkara Praperadilan tersebut mengabulkan gugatan yang diajukan Pemohon dan mengalahkan KPK. Kepastian hukum secara normatif adalah ketika suatu peraturan dibuat dan diundangkan secara pasti karena mengatur secara jelas dan logis. Jelas dalam artian tidak menimbulkan ke ragu-raguan (multi-tafsir) dan logis dalam artian menjadi sistem norma sehingga tidak berbenturan atau menimbulkan konflik norma. Permasalahan yang dikaji diantaranya Bagaimana dasar hukum hakim Praperadilan Sarpin Rizaldi memutuskan perkaranya dan Apakah putusan Praperadilan No. 04/Pid.Prap/2015/PN.Jaksel telah susuai dengan tujuan hukum yaitu keadilan, kepastian hukum dan kemanfaatan. Metode penelitian yang akan dipergunakan adalah melalui pendekatan yuridis normatif, spesifikasi penelitian menggunakan deskriptif analisis, data yang digunakan adalah data sekunder yang meliputi bahan hukum primer, bahan hukum sekunder, bahan hukum tertier, yang kemudian dianalisis secara kualitatif. Berdasarkan hasil penelitian diketahui bahwa langkah hakim Praperadilan melakukan rechtsvinding sudah tepat dan memang sudah seharusnya demikian, karena salah satu beberapa alasan perlunya melakukan penemuan hukum oleh hakim telah terpenuhi yaitu peraturan tidak ada, atau peraturannya ada tapi kurang jelas. Bahkan tanpa alasan-alasan tersebut pun, seorang hakim tetap dianggap melakukan penemuan hukum (dalam arti sempit) yaitu ketika ia menemukan kecocokan antara maksud atau bunyi peraturan perundang-undangan dengan kualifikasi peristiwa atau kasus konkritnya.
Effect of a modified nano clay and nano graphene on rheology, stability of water-in-oil emulsion, and filtration control ability of oil-based drilling fluids: a comparative experimental approach
Authors: Nooripoor Vahid , Hashemi Abdolnabi
Published: June 2020

During the past decade, researchers have used different Nano-Particles (NPs) due to their unique characteristics for improving formulation of Oil-Based Drilling Fluids (OBDFs). This study is the first research that investigates the effect of a Modified Nano Clay (MNC), namely CLOISITE 5 and non-functionalized Nano Graphene (NG) on rheology, electrical/emulsion stability, and filtration control ability, as the main properties of OBDFs. Initially, five concentrations of both NPs (0.25, 0.5, 1, 1.5, and 2 wt%) were added separately into an NP-free OBDF (the base fluid). Then, rheological properties and electrical stability of all prepared fluids were measured at three 90, 140, and 180 °F temperatures. Moreover, filtration test was carried out under 500 psi (3447 kPa) differential pressure and exposed to 300 °F temperature for all fluids. Since experimentally measured shear stresses followed well both Herschel Bulkley (shear-thinning) and Bingham Plastic models, effects of temperature and the NPs concentration on both model parameters are investigated more deeply in the paper. Activation energies calculated from Arrhenius model showed that MNC is more effective than NG on reducing the dependency of apparent and plastic viscosities of the base fluid on temperature. MNC, due to its amphiphilic structure, significantly stabilizes water-in-oil emulsion at all temperatures and concentrations, but NG with high electrical conductivity reduces the emulsion stability. The nanofluids containing 0.5 wt% MNC and 0.25 wt% NG which have respectively 32.6% and 43.5% fewer filtrate volumes than the base fluid, were considered as the optimal nanofluids from controlling filtration into formation aspect. Finally, MNC is applicable to enhance the formulation of the OBDF through supporting its commercial viscosifier, emulsifiers, and fluid loss control agent, but the negative effect of NG on emulsion stability limits its application.
A semi-implicit approach for the modeling of wells with inflow control completions
Authors: Flauraud Eric , Ding Didier Yu
Published: June 2020

In the last two decades, new technologies have been introduced to equip wells with intelligent completions such as Inflow Control Device (ICD) or Inflow Control Valve (ICV) in order to optimize the oil recovery by reducing the undesirable production of gas and water. To optimally define the locations of the packers and the characteristics of the valves, efficient reservoir simulation models are required. This paper is aimed at presenting the specific developments introduced in a multipurpose industrial reservoir simulator to simulate such wells equipped with intelligent completions taking into account the pressure drop and multiphase flow. An explicit coupling or decoupling of a reservoir model and a well flow model with intelligent completion makes usually unstable and non-convergent results, and a fully implicit coupling is CPU time consuming and difficult to be implemented. This paper presents therefore a semi-implicit approach, which links on one side to the reservoir simulation model and on the other side to the well flow model, to integrate ICD and ICV.

Stroke in the newborn. Clinical report and literature review
Authors: Jakuškienė R. , Joneliūnaitė V. , Jucevičiūtė U.
Published: June 2020

Background. Stroke in the newborn or perinatal stroke (PS) is an acute brain ischemia with the duration up to the first 28 days of life with neurological symptoms or without them. Therefore, the diagnostics in clinical practice can become tricky due to misleading expression of this clinical syndrome. Whilst rare (1 in 1600-4000 cases), PS has 6 times higher prevalence in newborns compared to older children. Consequently, slight neurological symptoms such as convulsions, changes or asymmetry in muscle tone, exaggeration, weakening or disappearance of primitive reflexes should be taken into account urgently. According to American Heart Association’s studies in 2019, two thirds of perinatal victims have neurological disability or delayed mental performance.Case report. In this article we present a clinical case of perinatal ischemic stroke and literature review. We analyze acute brain ischemia in a newborn which developed during the first 12-24 hours of life with severe neurological symptoms and involved the area of the right internal carotid artery. Apart from “fencing reflex” and feeding rejection, epilepsy was not marked in the history of PS onset. The doctors agreed on the diagnosis based on neurosonography and computed tomography results, and the decision of performing craniotomy was made due to the risk of hemorrhagic stroke.Conclusions. Diagnosing perinatal stroke is a crucial and difficult task for all pediatricians because of its poor clinical expression and the necessity of urgent actions in order to avoid long term outcomes. Hence, thorough neurological exam and neuroimaging is an essential point in early diagnostics. Clinical practice reveals that there are no common guidelines to diagnose and manage perinatal stroke as an extremely urgent pathology which has a significant impact on a child’s further mental development.

Published: June 2020

Narcolepsy is one of the central hypersomnias associated with a tetrad of symptoms: excessive daytime sleepiness, cataplexy, sleep paralysis, and hypnagogic hallucinations. On average, the accurate diagnosis of narcolepsy is made after 10.5 years after the onset of the disease, therefore the treatment is delayed causing a reduced quality of life. In this paper we present a clinical case of narcolepsy type 1 causing both diagnostic and therapeutic challenges. Furthermore, the most common symptoms of narcolepsy, diagnosis, treatment options as well as possibilities to implement them in Lithuania are overviewed in this article.
Small fiber neuropathy: clinical presentation, diagnostic methods, possibly causes and treatment
Authors: Paulėkas E. , Garšvienė D. , Petrikonis K.
Published: June 2020

Small fiber neuropathy (SFN) is a disorder affecting the thin myelinated Aδ and unmyelinated C nerve fibers, which usually presents clinically with symmetrical, length-dependent neuropathic and autonomic symptoms. In some cases, a non-length-dependent clinical presentation may develop instead, characterized by focal or multifocal symptoms. Diagnosis of pure SFN remains difficult in situations when no pathological findings are detected during nerve conduction tests (using standard electroneuromyography) and patients present with unusual subjective symptoms. However, quantitative measurement of intraepidermal nerve fiber density (INFD) in skin biopsy and quantitative evaluation of sensory or autonomic symptoms may facilitate the diagnostic process. There is a plethora of possible SFN causes, such as metabolic, immune system mediated or neurotoxic factors, although in about 50% of cases, the precise etiology remains unknown. In recent years, mutations in genes SCN9A and SCN10A that encode voltage-gated sodium channels Nav1.7 and Nav1.8, respectively, have been linked to nearly a third of SFN cases that previously were thought of as idiopathic. In clinical practice, it is important to identify possible SFN causes and prescribe medications that not only treat the symptoms but directly intervene in the etiopathogenetic mechanisms of the disorder itself. In this review, we examine clinical signs, possible causes, available diagnostic methods and treatment of SFN.

Background. Migraine prevalence in Lithuania is 18.8%. The aim of this study was to evaluate the prevalence of migraine, quality of life, professionally confirmed diagnosis rate, and treatment among medical students (aged 18-28 years) in 2010-11 and in 2019.Materials and methods. 478 Vilnius university medicine and odontology students participated in the anonymous survey. 252 students were queried in 2010-11 study (aged 23.0±7.8) and 226 in 2019 (aged 23.0±1.5). Questionnaire consisted of questions, based on headache characteristics, triggers, impact on life, presence of confirmed diagnosis, and treatment. The data was analyzed by SPSS 23.0 software, a p value of <0.05 was considered significant.Results. Based on questionnaire, prevalence of migraine with and without aura remained stable between the periods of 2010-11 (27.8%) and 2019 (27.9%) (p=0.98); women were affected more often (p=0.02). Pain remained moderately intense (p=0.07), but migraine disability worsened over the time (p=0.01). Migraine was professionally diagnosed more often in 2019 (10% vs. 25.4%, p=0.03); increased use of specific acute therapy (5.7% vs. 19%, p=0.03) and prophylaxis (0% vs 9.6%, p=0.003) was observed. Likelihood of diagnosis significantly increased with more intense pain (OR=2.7, p=0.006) and aura (OR=2.7, p=0.037). Presence of confirmed diagnosis was an independent determinant of increased triptans (OR=6.9, p=0.012) and prophylaxis (OR=30.3, p=0.036) use.Conclusions. Comparing the 2010-11 and 2019 periods, migraine prevalence is similar. Pain remains to be valued as moderate, but quality of life has worsened. Prevalence of professionally diagnosed migraine has increased over the time, what was accompanied by an increased use of triptans and prophylaxis, however, migraine still remains underdiagnosed and undertreated.
