Objective:Laboratory evaluation of the relationship between cerebrospinal fluid and plasma indicators and intrathecal immunoglobulin G(IgG) synthesis in patients with neurological diseases, and establishment of a new diagnostic method for intrathecal IgG synthesis.Methods:This study retrospectively analyzed the content of IgG in cerebrospinal fluid samples and blood albumin in blood samples, and other test results of 410 patients with neurological diseases who visited Beijing Tiantan Hospital from 2019 to 2022. According to the results of oligoclonal bands in cerebrospinal fluid, patients were divided into intrathecal IgG synthesis group and non-intrathecal IgG synthesis group. The Mann Whitney U test was used for inter group comparison, and a bilateral test with P<0.05 indicates a statistically significant difference. Include indicators with differences between groups in logistic regression analysis, construct a predictive model, and compare it with the established quantitative formula IgG index. Results:There were significant differences in 10 indicators, including cerebrospinal fluid leukocyte count and 24-hour intrathecal IgG synthesis rate, between the intrathecal IgG synthesis group and the non-intrathecal IgG synthesis group, with P<0.05. The area under the curve (AUC) of intrathecal IgG synthesis was higher than the IgG index (AUC=0.920, 0.809, Z=31.178, P<0.001), the sensitivity was higher than the IgG index (0.825, 0.618), and the specificity was lower than the IgG index (0.876, 0.908). Conclusion:The combination of 10 indicators such as cerebrospinal fluid white blood cell count and 24-hour intrathecal IgG synthesis rate can improve the diagnostic efficacy and sensitivity of intrathecal IgG synthesis.

Objective:To investigate the clinical and electrophysiological characteristics of ANCA-associated vasculitic neuropathy (VN) and analyze the predictors of treatment outcomes.Methods:Retrospective case series. In all, 652 consecutive patients with ANCA-associated vasculitis were admitted to the First Medical Center of the Chinese PLA General Hospital between January 2006 and December 2022. Peripheral neuropathy occurred in 91 patients. Patients were excluded if other known causes of neuropathy were present. Sixty-one patients were eventually enrolled, including 17 with eosinophilic granulomatosis with polyangiitis (EGPA), 11 with granulomatosis polyangiitis (GPA), and 33 with microscopic polyangiitis (MPA). Their clinical data were collected and clinical characteristics, VN manifestations, electrophysiological findings (including interside amplitude ratio [IAR]), and treatment outcomes were compared among the three subsets of AAV. Then, factors influencing the treatment outcomes were analyzed using multivariable logistic regression analysis.Results:Peripheral neuropathy occurred in 62.1%(18/29) of EGPA, 8.3%(15/180) of GPA, and 13.1%(58/443) of MPA patients. The age at onset and examination was higher in patients with MPA than those with EGPA or GPA ( P<0.01). The occurrence of VN was later in patients with GPA than those with EGPA ( P<0.01), and the GPA group had fewer affected nerves than the other two groups ( P<0.016). The abnormal IARs of motor nerves in lower limbs were more detected in the EGPA than the MPA group ( P<0.01). Logistic regression analysis suggested that higher Birmingham vasculitis activity score-version 3 (BVAS-V3) ( OR=6.85, 95% CI 1.33-35.30) was associated with better treatment outcomes of VN. However, central nervous system involvement was a risk factor for poor treatment outcomes ( OR=0.13, 95% CI 0.02-0.89). Conclusions:The clinical and electrophysiological characteristics of VN were slightly different among subsets of AAV. Patients with GPA often presented with polyneuropathy and had fewer nerves affected; mononeuritis multiplex was more common in EGPA than GPA and MPA. Higher BVAS-V3 and central nervous system involvement might predict the treatment outcome of VN.

Objective:To explore the clinical and electrophysiological characteristics of peripheral neuropathy in prediabetic patients.Methods:Subjects aged 20-65 years with high-risk factors of impaired glycemia enrolled in Beijing Tiantan Hospital, Capital Medical University from 2019 to 2022 were recruited to conduct oral glucose tolerance test, after excluding other causes of neuropathy or radiculopathy. Patients with impaired fasting glucose or impaired glucose tolerance were defined by American Diabetes Association criteria. These patients were divided into clinical polyneuropathy (PN) and clinical non-PN groups, according to the 2010 Toronto consensus criteria and the presence of PN symptoms and signs or not. Nerve conduction studies (NCS), F wave, sympathetic skin response (SSR), R-R interval variation (RRIV) and current perception thresholds (CPT) were performed and the abnormal rate was compared between different electrodiagnostic methods and between clinical subgroups.Results:Among the 73 prediabetic patients ultimately enrolled, only 20 (27.4%) can be diagnosed as clinical PN according to the Toronto consensus criteria. The abnormal rate of CPT (68.5%, 50/73) was significantly higher than those of F wave (2.7%, 2/73), lower limb NCS (0, 0/73), upper limb NCS changes of carpal tunnel syndrome (26.0%, 19/73), SSR (6.8%, 5/73) and RRIV (5.5%, 4/73; McNemar test, all P<0.001). With sinusoid-waveform current stimuli at frequencies of 2 000 Hz, 250 Hz and 5 Hz, the CPT device was used to measure cutaneous sensory thresholds of large myelinated, small myelinated and small unmyelinated sensory fibers respectively. CPT revealed a 21.9% (16/73) abnormal rate of unmyelinated C fiber in the hands of prediabetic patients, significantly higher than that of large myelinated Aβ fibers [8.2% (6/73), χ2=5.352, P=0.021]. Both abnormal rates of small myelinated Aδ [42.5% (31/73)] and unmyelinated C fibers [39.7% (29/73)] in the feet of prediabetic patients were significantly higher than that of large myelinated Aβ fibers [11.0% (8/73), χ2=18.508, 15.965, both P<0.001]. Compared with the clinical non-PN group, the abnormal rates of CPT [90.0% (18/20) vs 60.4% (32/53), χ2=5.904, P=0.015] and SSR [20.0% (4/20) vs 1.9% (1/53), P=0.016) were significantly higher in the clinical PN group. Conclusions:Peripheral neuropathies in prediabetic patients are usually asymptomatic or subclinical, and predispose to affect unmyelinated and small myelinated sensory fibers. Selective electrodiagnostic measurements of small fibers help to detect prediabetic neuropathies in the earliest stages of the disease.

Peripheral neuropathies are commonly diagnosed in different clinical department of the hospital. The diagnosis is generated by a set of reasonable process based on the manifestations of patients. According to the age of onset, the speed of disease development and the symptoms of peripheral nerve lesions, the peripheral neuropathy is divided into a definite clinical subtype for a particular patient. On this basis, utility of the nerve conduction studies and electromyography is conducted to confirm the anatomical locations of peripheral neuropathy. The etiologic diagnosis is based on anatomical diagnosis of peripheral nerve with a reasonable choice of auxiliary tests, including serological testing, peripheral nerve imaging and biopsy. Genetic tests are chosen for patients with clinical suspective diagnosis of hereditary disease. Finally, therapy evaluation on the basis of etiologic diagnosis is important for forming a treatment plan.

As a key regulator of neuronal growth, development and synaptic plasticity, BDNF/ TrkB signaling pathway is widely involved in the occurrence and development of central nervous system diseases, such as ischemic stroke, Alzheimer's disease, Parkinson's disease and spinal cord injury. Studies have shown that acupuncture can regulate the activity of BDNF/TrkB signaling pathway, and has significant therapeutic potential for these diseases. Its mechanism of action is related to participating in synaptic remodeling, inhibiting neuronal apoptosis, and promoting neurogenesis or synaptic regeneration. This article reviews the role of BDNF/TrkB signaling pathway in central nervous system diseases and the regulation mechanism of acupuncture on this pathway, in order to provide new ideas for clinical treatment. Future studies should further explore the precise regulatory mechanism of acupuncture on BDNF/TrkB signaling pathway in order to develop more efficient and safe treatment strategies.

ABSTRACT We present an unusual case of a 13-year-old male pediatric patient with a diagnosis of sphenoid sinus mucocele. The patient suffered a progressive loss of visual acuity over three months followed by a total recovery of his visual acuity after surgery. The patient presented at the emergency room complaining of progressive loss of visual acuity in his left eye which decreased to hand motion over the preceding months. Imaging studies revealed a cystic mass, suggestive of sphenoid sinus mucocele, which was causing compressive optic neuropathy and proptosis. The patient was scheduled for a sphenoidectomy and resection of the mass. Three days after surgery, the patient's visual acuity in the left eye was 20/20, indicating complete recovery from his symptoms. We suggest that the excellent outcome in this patient may be attributable to his age. His ongoing physical development might have been the decisive factor in the recovery of his visual acuity following compressive optic neuropathy secondary to sphenoid sinus mucocele. Further research is needed to verify this proposed explanation.
RESUMO Apresentamos um caso incomum de paciente pediátrico com diagnóstico de mucocele de seio esfenoidal, que apresentou perda progressiva da acuidade visual ao longo de três meses, resultando em recuperação total da acuidade visual após a cirurgia. Paciente do sexo masculino, 13 anos, procurou o pronto-socorro, queixando-se de perda progressiva da acuidade visual do olho esquerdo nos últimos três meses. Exames de imagem revelaram uma massa cística sugestiva de mucocele de seio esfenoidal, causando neuropatia óptica compressiva e proptose. O paciente foi agendado para esfenoidectomia e ressecção da massa. Três dias após a cirurgia, a acuidade visual do paciente no olho esquerdo era de 20/20, apresentando recuperação completa dos sintomas. Diante dos resultados de nosso paciente, sugerimos que a idade do paciente pode ser decisiva na recuperação da acuidade visual de uma neuropatia óptica compressiva secundária à mucocele de seio esfenoidal. Mais pesquisas são necessárias para verificação desses dados.

ABSTRACT Purposes: To assess the efficacy of botulinum toxin A injection in the treatment of strabismus in patients with neurological impairment and evaluate the factors associated with treatment success. Methods: The study included 50 patients with strabismus and neurological impairment. In all children, botulinum toxin injection was performed into the appropriate extraocular muscle. The relationship between demographic features, clinical characteristics, and treatment success were analyzed. Results: In the study group, 34 patients had esotropia, and 16 patients had exotropia. As neurological problems, 36 patients had cerebral palsy, and 14 had hydrocephalus. The average follow-up period was 15.3 ± 7.3 months. The mean number of injections was 1.4 ± 0.6. The mean angle of deviation was 42.5 ± 13.2 PD before the treatment, which decreased to 12.8 ± 11.9 PD after the treatment. Successful motor alignment (orthotropia within 10 PD) was achieved in 60% of the patients. Binary logistic regression analysis revealed that esotropic misalignment and shorter duration of strabismus was significantly associated with treatment success in the study group. Patients with esotropia and lower angles of misalignment were more likely to be treated with a single injection. Conclusion: The use of botulinum toxin A for the treatment of strabismus in children with neurological impairment is a good alternative to conventional surgical therapy with a lower risk of overcorrection. The treatment outcome is better in esodeviations and shorter duration of strabismus, implying an advantage of early treatment.
RESUMO Objetivos: Avaliar a eficácia do uso de toxina bo-tulínica tipo A no tratamento do estrabismo em pacientes com comprometimento neurológico e avaliar os fatores associados ao sucesso do tratamento. Métodos: Cinquenta pacientes com estrabismo e comprometimento neurológico foram incluídos no estudo. Em todas as crianças, a toxina botulínica tipo A foi injetada no músculo extraocular apropriado. A relação entre características demográficas, características clínicas e o sucesso do tratamento foram analisadas. Resultados: No grupo de estudo, 34 pacientes tiveram esotropia e 16 pacientes tiveram exotropia, sendo trinta e seis pacientes com paralisia cerebral e 14 pacientes com hidrocefalia. O tempo médio de acompanhamento foi de 15,3 ± 7,3 meses. O número médio de aplicações foi de 1,4 ± 0,6. O ângulo de desvio médio foi de 42,5 ± 13,2 DP antes do tratamento e diminuiu para 12,8 ± 11,9 DP após o tratamento. Alinhamento motor bem sucedido (ortotropia dentro de 10 DP) foi alcançado em 60% dos pacientes. A análise de regressão logística binária revelou que o desalinhamento esotrópico e uma menor duração do estrabismo foram significativamente associados ao sucesso do tratamento no grupo de estudo. Pacientes esotrópicos com ângulos de desalinhamento menores são mais propensos a serem tratados com uma única aplicação. Conclusão: O uso da toxina botulínica tipo A para o tratamento de estrabismo em crianças com comprometimento neurológico é uma boa alternativa para a terapia cirúrgica convencional com menor risco de hipercorreção. O resultado do tratamento é melhor em exodesvios e em pacientes com estrabismo de menor duração, implicando em vantagem para o tratamento precoce.

Abstract Background In 2012, the Neurocritical Care Society launched a compilation of protocols regarding the core issues that should be addressed within the first hours of neurological emergencies - the Emergency neurological life support (ENLS). Objective We aim to evaluate this repercussion through a bibliometric analysis. Methods We searched Scopus on October 2022 for articles mentioning ENLS. The following variables were obtained: number of citations; number of citations per year; number of publications per year; year of publication; research type; research subtype; country of corresponding author and its income category and world region; journal of publication and its 5-year impact factor (IF); and section where ENLS appeared. Results After applying eligibility criteria, we retrieved 421 articles, published from 2012 to 2022. The mean number of citations per article was 17.46 (95% Confidence Interval (CI) = 8.20-26.72), while the mean number of citations per year per article was 4.05 (95% CI = 2.50-5.61). The mean destiny journal 5-year IF was 5.141 (95% CI = 4.189-6.093). The majority of articles were secondary research (57.48%; n= 242/421) of which most were narrative reviews (71.90%; n= 174/242). High-Income countries were the most prominent (80.05%; n= 337/421 articles). There were no papers from low-income countries. There were no trials or systematic reviews from middle-income countries. Conclusion Although still low, the number of publications mentioning ENLS is increasing. Articles were mainly published in journals of intensive care medicine, neurology, neurosurgery, and emergency medicine. Most articles were published by authors from high-income countries. The majority of papers were secondary research, with narrative review as the most frequent subtype.

Abstract Background Guillain-Barré syndrome (GBS) is the most common cause of acute flaccid paralysis worldwide and can be classified into electrophysiological subtypes and clinical variants. Objective This study aimed to compare the frequency of the sural-sparing pattern (SSP) in subtypes and variants of GBS. Methods This retrospective cohort study analyzed clinical and electrophysiological data of 171 patients with GBS hospitalized in public and private hospitals of Natal, Rio Grande do Norte, Brazil, between 1994 and 2018; all cases were followed up by the same neurologist in a reference neurology center. Patients were classified according to electrophysiological subtypes and clinical variants, and the SSP frequency was compared in both categories. The exact Fisher test and Bonferroni correction were used for statistical analysis. Results The SSP was present in 53% (57 of 107) of the patients with acute inflammatory demyelinating polyradiculoneuropathy (AIDP), 8% (4 of 48) of the patients with axonal subtypes, and 31% (5 of 16) of the equivocal cases. The SSP frequency in the AIDP was significantly higher than in the axonal subtypes (p < 0.0001); the value was kept high after serial electrophysiological examinations. Only the paraparetic subtype did not present SSP. Conclusion The SSP may be present in AIDP and axonal subtypes, including acute motor axonal neuropathy, but it is significantly more present in AIDP. Moreover, the clinical variants reflect a specific pathological process and are correlated to its typical electrophysiological subtype, affecting the SSP frequency.
Resumo Antecedentes A síndrome de Guillain-Barré (GBS) é a causa mais comum de paralisia flácida aguda em todo o mundo e pode ser classificada em subtipos eletrofisiológicos e variantes clínicas. Objetivo Este estudo teve como objetivo comparar a frequência do padrão de preservação do sural (SSP) em subtipos e variantes de GBS. Métodos É um estudo de coorte retrospectivo que analisou dados clínicos e eletrofisiológicos de 171 pacientes com GBS internados em hospitais públicos e privados de Natal, Rio Grande do Norte, Brasil, entre 1994 e 2018. Todos os casos foram acompanhados pelo mesmo neurologista em centro de referência em neurologia. Os pacientes foram classificados de acordo com os subtipos eletrofisiológicos e variantes clínicas e a frequência do SSP foi comparada em ambas as categorias. O teste exato de Fisher e a correção de Bonferroni foram utilizados para análise estatística. Resultados O SSP esteve presente em 53% (57 de 107) dos pacientes com polirradiculoneuropatia desmielinizante inflamatória aguda (PDIA), em 8% (4 de 48) dos pacientes com subtipos axonais e em 31% (5 de 16) dos casos não definidos. A frequência do SSP no AIDP foi significativamente maior do que nos subtipos axonais (p < 0,0001); o valor manteve-se elevado após exames eletrofisiológicos seriados. Apenas o subtipo paraparético não apresentou SSP. Conclusão O SSP pode estar presente na PDIA e nos subtipos axonais, incluindo a neuropatia axonal motora aguda, mas está significativamente mais presente na PDIA. Além disso, as variantes clínicas refletem um processo patológico específico e estão correlacionadas ao seu subtipo eletrofisiológico típico, afetando a frequência do SSP.

Abstract Background Hereditary transthyretin amyloidosis (ATTRv) is an inherited, progressive, and fatal disease still largely underdiagnosed. Mutations in the transthyretin (TTR) gene cause the TTR protein to destabilize, misfold, aggregate, and deposit in body tissues, which makes ATTRv a disease with heterogeneous clinical phenotype. Objective To describe the long-term efficacy and safety of inotersen therapy in patients with ATTRv peripheral neuropathy (ATTRv-PN). Methods Patients who completed the NEURO-TTR pivotal study and the NEURO-TTR OLE open-label extension study migrated to the present study and were followed-up for at least 18 more months to an average of 67 months and up to 76 months since day 1 of the inotersen therapy (D1-first dose of inotersen). Disease progression was evaluated by standard measures. Results Ten ATTRv-PN patients with Val30Met mutation were included. The mean disease duration on D1 was of 3 years, and the mean age of the patients was of 46.8 years. During an additional 18-month follow up, neurological function, based on the Neuropathy Impairment Score and the Polyneuropathy Disability Score, functionality aspects (Karnofsky Performance Status), and nutritional and cardiac aspects were maintained. No new safety signs have been noted. Conclusion The treatment with inotersen was effective and well tolerated for the average of 67 months and up to 76 months. Our results are consistent with those of larger phase-III trials.
Resumo Antecedentes Amiloidose hereditária por transtirretina (ATTRv) é uma doença hereditária, progressiva e fatal ainda largamente subdiagnosticada. Mutações no gene transtirretina (TTR) promovem desestabilização, desdobramento, agregação e depósito da proteína TTR em tecidos do corpo, o que faz da ATTRv uma doença de fenótipo clínico heterogêneo. Objetivo Descrever a eficácia e segurança da terapia com inotersena no longo prazo em pacientes com neuropatia periférica ATTRv (ATTRv-PN). Métodos Pacientes que completaram o estudo pivotal NEURO-TTR e o estudo de extensão aberta NEURO-TTR OLE migraram para este estudo e foram acompanhados por no mínimo 18 meses adicionais, em média por 67 meses, e por até 76 meses, desde o dia 1 da terapia com inotersena (D1-primeira dose de inotersena). A progressão da doença foi avaliada por medidas padronizadas. Resultados Dez pacientes com ATTRv-PN com mutação Val30Met foram incluídos. A duração média da doença no D1 era de 3 anos, e a média de idade dos pacientes era de 46,8 anos. Durante o período de acompanhamento adicional de 18 meses, a função neurológica, baseada no Neuropathy Impairment Score e no Polyneuropathy Disability Score, os aspectos de funcionalidade (Karnofsky Performance Status), nutricional e cardíacos estavam mantidos. Não se observou nenhum novo sinal de segurança. Conclusão O tratamento com inotersena foi eficaz e bem tolerado por 67 meses em média, e por até 76 meses. Nossos resultados são consistentes com os de estudos maiores de fase III.

ABSTRACT BACKGROUND: Among the complications related to chronic kidney disease (CKD), those of a neurological nature stand out, and for a better quality of life for patients, the diagnosis and treatment of these complications is fundamental. OBJECTIVES: This study aimed to assess the effect of hemodialysis on intracranial pressure waveform (ICPw) in patients with chronic kidney disease undergoing hemodialysis and those who are not yet undergoing substitutive therapy. DESIGN AND SETTING: An observational study was conducted in two stages at a kidney replacement therapy center in Brazil. The first was a longitudinal study and the second was a cross-sectional study. METHODS: Forty-two patients on hemodialysis were included in the first stage of the study. In the second stage, 226 participants were included. Of these, 186 were individuals with chronic kidney disease (who were not undergoing substitutive therapy), and 40 did not have the disease (control group). The participants' intracranial compliance was assessed using the non-invasive Brain4care method, and the results were compared between the groups. RESULTS: There was a significant difference between the hemodialysis and non-hemodialysis groups, with the former having better ICPw conditions. CONCLUSIONS: Hemodialysis influenced the improvement in ICPw, probably due to the decrease in the patients' extra-and intracellular volumes. Furthermore, ICPw monitoring can be a new parameter to consider when defining the moment to start substitutive therapy.

Propósito: La neuropatía periférica tiene un espectro clínico inespecífico y multifactorial, con frecuente subdiagnóstico y terapéutica de eficacia variable. Existe una heterogénea prescripción de vitaminas B, las cuales pueden desempeñar un rol importante en el manejo de diferentes neuropatías; sin embargo, en Colombia no existen guías clínicas al respecto. El propósito de este trabajo es orientar en el reconocimiento temprano de las neuropatías periféricas y generar recomendaciones sobre el uso adecuado de vitaminas B neurotrópicas. Descripción de la metodología: Acuerdo de expertos sobre la neuropatía periférica y el rol terapéutico de las vitaminas B con énfasis en la epidemiología en Colombia, diagnóstico y tratamiento. Contenidos: En Colombia, la prevalencia de neuropatía periférica se estima cercana al 10 %, sin embargo, no hay datos recientes. Dentro de las etiologías más frecuentes se encuentran la neuropatía diabética, infecciosa, inflamatoria, carenciales, toxica y farmacológica. Se recomiendan las siguientes herramientas de tamizaje en población de riesgo: DN4, MNSI, test de monofilamento, test de vibración y valoración de reflejos. Las vitaminas B1, B6 y B12 son seguras, accesibles y pueden ser eficaces en neuropatía periférica, incluso cuando el déficit no ha sido demostrado, pero con requerimientos particulares en su administración conjunta. Conclusiones: Las neuropatías periféricas son un reto diagnóstico y terapéutico que requiere la identificación oportuna para el tratamiento de la etiología subyacente y el control de síntomas. El uso de vitaminas B neurotrópicas es efectivo y seguro en neuropatía periférica carencial, y también parece ser eficaz en el manejo de neuropatías periféricas de diferentes etiologías.
Purpose: Peripheral neuropathy has a nonspecific and multifactorial clinical spectrum, with frequent underdiagnosis and therapeutics of variable efficacy. There is a high but heterogeneous prescription of B vitamins, which can play an important role in the management of different neuropathies; however, in Colombia there are no clinical guidelines in this regard. The purpose of this article is to guide the early recognition of peripheral neuropathy and generate recommendations on the proper use of neurotropic B vitamins. Description of the methodology: Expert agreement on peripheral neuropathy and the therapeutic role of B vitamins with emphasis on epidemiology in Colombia, diagnosis and treatment. Contents: In Colombia, there are no recent data to estimate the prevalence of peripheral neuropathy; the main etiologies are: diabetes mellitus, nutritional deficiencies, herpes zoster and neuropathies due to chemotherapy. Given risk factors in the anamnesis, the use of DN4, MNSI, monofilament test, vibration test and assessment of reflexes is recommended. Vitamins B1, B6, and B12 are safe and can be effective in peripheral neuropathy, even when the deficit has not been demonstrated, but with special requirements in their joint administration. Conclusions: peripheral neuropathies are a diagnostic and therapeutic challenge, and require timely identification, for the treatment of the underlying etiology and symptom control. The use of neurotropic B vitamins is effective and safe in deficient peripheral neuropathy, and also appears to be effective in the management of peripheral neuropathies of different etiologies.

Objective: Review the relationship between Multiple Sclerosis (MS) and the cardiovascular (CV) system, as well as the CV manifestations of the disease and the CV complications of treatment. Methods: We performed a non-systematic review of the main databases, with no time limit. Results: People with MS tend to have a different CV risk than the general population, with a higher prevalence of hypertension, hyperlipidemia, overweight, ischemic heart disease, and peripheral and cerebral artery disease. In addition, cardiac alterations can be present in any part of MS patient care. Furthermore, MS treatments are not innocuous for the CV system and require attention, especially considering fingolimod and mitoxantrone. Discussion: The findings could partially explain the higher mortality rates found in this population. Furthermore, at the onset, dysautonomia symptoms, like postural orthostatic tachycardia syndrome, can be used as a clinical marker of patients at higher risk to evolve from clinically isolated syndrome to MS. Finally, MS not only progress badly when associated with CV risk factors but are also at increased risk of CV morbidity and mortality. Conclusion: Physicians addressing MS patients should be aware of their increased cardiovascular risk and the impact that adequate control of these factors can have on disease progression, patient lifespan, and global care.
Objetivo: Analisar a relação entre a esclerose múltipla (EM) e o sistema cardiovascular (CV), bem como as manifestações CV da doença e as complicações CV do tratamento. Métodos: Foi realizada uma revisão não sistemática das principais bases de dados, sem limite de tempo. Resultados: Pessoas com EM tendem a ter um risco CV diferente da população em geral, com maior prevalência de hipertensão, hiperlipidemia, sobrepeso, cardiopatia isquêmica e doença arterial periférica e cerebral. Além disso, as alterações cardíacas podem estar presentes em qualquer parte do tratamento do paciente com EM. Além disso, os tratamentos da EM não são inócuos para o sistema CV e requerem atenção, especialmente considerando o fingolimod e a mitoxantrona. Discussão: Os achados podem explicar parcialmente as taxas de mortalidade mais altas encontradas nessa população. Além disso, no início, os sintomas de disautonomia, como a síndrome de taquicardia postural ortostática, podem ser usados como um marcador clínico de pacientes com maior risco de evoluir da síndrome clinicamente isolada para a EM. Por fim, a EM não só progride mal quando associada a fatores de risco CV, mas também apresenta um risco maior de morbidade e mortalidade CV. Conclusão: Os médicos que lidam com pacientes com EM devem estar cientes de seu risco cardiovascular aumentado e do impacto que um controle adequado desses fatores pode ter na progressão da doença, no tempo de vida do paciente e nos cuidados globais.

Los avances tecnológicos y del conocimiento hicieron que un mayor número de pacientes con enfermedad crónica gastrointestinal pasen de ser atendidos por el pediatra al control por los médicos de adultos durante una de las etapas más vulnerables de la vida: la adolescencia. El Grupo de Trabajo de Transición del Comité de Gastroenterología de la Sociedad Argentina de Pediatría realizó una búsqueda de literatura exhaustiva y convocó a especialistas referentes del país, con el objeto de unificar los criterios basados en la evidencia y la experiencia. De esta manera, se proponen una serie de recomendaciones para todo el equipo de salud (pediatra, gastroenterólogo infantil, nutricionista, gastroenterólogo de adultos, psicólogo, enfermería), incluso para pacientes y familias, que faciliten el proceso de transición y optimicen el seguimiento, el control, la prevención de complicaciones y la calidad de vida de los pacientes con enfermedades crónicas gastrointestinales
Technological advances and the globalization of knowledge have led to a considerable increase in the number of patients with chronic gastrointestinal disease who transition from pediatric to adult care during one of the most vulnerable life stages: adolescence. The Transition Working Group of the Gastroenterology Committee of the Sociedad Argentina de Pediatría conducted an exhaustive literature search and summoned leading specialists in the most frequent chronic pathologies from all over the country to unify criteria based on evidence and experience. As a result, a series of recommendations are proposed for the whole health team (pediatrician, pediatric gastroenterologist, nutritionist, adult gastroenterologist, psychologist, and nurse) including patients and families, to facilitate the transition process, optimize follow-up, prevent complications, and improve the quality of life of patients with chronic gastrointestinal diseases.

Fundamento: los trastornos del sodio son los más comunes y menos entendidos en pacientes con lesión cerebral aguda debido al papel principal que desempeña el sistema nervioso central en la regulación de la homeostasis del sodio y agua lo que puede llevar a complicaciones graves y resultados adversos, incluyendo la muerte. Objetivo: determinar la contribución a la mortalidad de la hipernatremia en pacientes con estado crítico por afecciones neurológicas. Métodos: estudio observacional analítico sobre 55 pacientes que ingresaron en las unidades de atención al grave del Hospital Universitario Arnaldo Milián Castro, entre octubre del 2020 y mayo del 2022, con independencia del valor del sodio plasmático a su admisión en el servicio, así como durante su estadía en las unidades de atención al grave. Se emplearon métodos estadísticos univariados y bivariados en el análisis de los datos. Resultados: el promedio de edad fue de 60±16 años. Los diagnósticos más relevantes fueron la hemorragia intraparenquimatosa (56,37 %), el trauma craneoencefálico y el accidente cerebrovascular isquémico (ambos 30 %). Las concentraciones plasmáticas de sodio mostraron diferencias significativas (pX2= 0,000), siendo la media mayor a las 24 horas de ingreso (174,2±133,6) y la menor al 5to día (102,9±72,9). Existió correlación significativa entre las concentraciones plasmáticas de sodio al ingreso ( 24 h y 72 h) y el estado al egreso. En el análisis bivariado individual por período, solo a las 24 horas hubo relación significativa, en este periodo la hipernatremia contribuyó a la mortalidad en 1,78 veces más que en aquellos que no tenían el sodio elevado (OR=1,78 con IC: 1,39-3,4). Conclusiones: la hipernatremia en el paciente con estado crítico por afecciones neurológicas se asocia con incremento de la mortalidad.
Background: sodium disorders are the most common and least understood in patients with acute brain injury due to the major role played by the central nervous system in regulating sodium and water homeostasis, which can lead to serious complications and adverse outcomes, including death. Objective: to determine the hypernatremia contribution to mortality in patients with neurological conditions in critical state. Methods: longitudinal analytical observational study on 55 patients who were admitted to the acute care units at the Arnaldo Milián Castro University Hospital, between October 2020 and May 2022, regardless of the plasma sodium value upon admission to the service, as well as during their stay in the critical care units. Univariate and bivariate statistical methods were used in data analysis. Results: the average age was 60 ± 16 years. The most relevant diagnoses were intraparenchymal hemorrhage (56.37%), head trauma, and ischemic stroke (both 30%). Plasma sodium concentrations showed significant differences (pX2= 0.000), with the highest average at 24 hours of admission (174.2 ± 133.6) and the lowest at the 5th day (102.9 ± 72.9). There was a significant correlation between plasma sodium concentrations at admission, 24h and 72h with the state at discharge. In the individual bivariate analysis by period, there was only a significant relationship after 24 hours. In this period, hypernatremia contributed 1.78 times more to mortality than in those who did not have elevated sodium (OR=1.78 with CI: 1,39-3,4). Conclusions: hypernatremia in critically ill patients with neurological conditions is associated with increased mortality.

Introducción: la disfagia es un trastorno de la deglución, el cual es habitualmente desatendido por profesionales de la salud, en especial la disfagia orofaríngea neurogénica, que es capaz de producir varios síntomas, signos y complicaciones secundarias en los pacientes. Objetivo: realizar una caracterización clínica incluyendo percepción de síntomas de disfagia en pacientes con disfagia orofaríngea neurogénica de causas neurológicas y neuromusculares en Antioquia, Colombia entre los años 2019 y 2021. Metodología: estudio transversal realizado en 80 pacientes con disfagia orofaríngea neurogénica confirmada a través de la herramienta Eating Assessment Tool-10, evaluación clínica y/o resultados de video fluoroscopia de la deglución. Resultados: 71 pacientes presentaron causas neurológicas centrales. La enfermedad cerebrovascular y la enfermedad de Parkinson fueron las etiologías más frecuentes. Solo 18% de los pacientes con causas neurológicas y 33% con causas neuromusculares reportaron tolerancia a todas las consistencias de alimentos. Mediana de 16 puntos en cuanto a autopercepción de síntomas de disfagia mediante el instrumento Eating Assessment Tool-10, con puntuaciones más altas en pacientes con presencia de gastrostomía, antecedente de neumonía, odinofagia y alteración en la oclusión mandibular al examen físico. En los pacientes con causas neurológicas hubo mayor presencia de signos motores linguales y apraxias orofaciales. Conclusión: existen características clínicas como sensación de comida pegada, dificultad para tragar alimentos sólidos, tos y ahogo al tragar, que son útiles en el reconocimiento de casos de disfagia orofaríngea, y apoyan que esta genera más síntomas que signos al examen físico en pacientes con condiciones neurológicas y neuromusculares.
Introduction: dysphagia is a swallowing disorder that is usually neglected by health professionals, especially neurogenic oropharyngeal dysphagia, which can produce various symptoms, signs and secondary complications in patients. Objective: to perform a clinical characterization, including perception of dysphagia symptoms, in patients with neurogenic oropharyngeal dysphagia of neurological and neuromuscular causes in Antioquia, Colombia between 2019 and 2021. Methodology: cross-sectional study conducted in 80 patients with neurogenic oropharyngeal dysphagia confirmed through the Eating Assessment Tool-10, clinical assessment and/ or video fluoroscopy results of swallowing. Results: 71 patients presented central neurological causes. Cerebrovascular disease and Parkinson's disease were the most frequent etiologies. Only 18% of patients with neurological causes and 33% with neuromuscular causes reported tolerance to all food consistencies. Median of 16 points in terms of self-perception of dysphagia symptoms using the Eating Assessment Tool-10, with higher scores in patients with gastrostomy, a history of pneumonia, odynophagia, and abnormal mandibular occlusion on physical examination. In patients with neurological causes, there was a greater presence of lingual motor signs and orofacial apraxia. Conclusion: there are clinical characteristics such as a sensation of stuck food, difficulty swallowing solid foods, coughing, and choking when swallowing, which are useful in recognizing cases of oropharyngeal dysphagia, and support that this generates more symptoms than signs on physical examination in patients with neurological and neuromuscular conditions.
