Patients with KCNJ11-related diabetes frequently have neuropsychological impairments compared with sibling controls.

AIMS: KCNJ11-related diabetes is the most common form of permanent neonatal diabetes and has been associated with a spectrum of neurodevelopmental problems. We compared neurodevelopmental outcomes in patients with KCNJ11 mutations and their sibling controls. METHODS: Through our Monogenic Diabetes Registry (http://monogenicdiabetes.uchicago.edu/), we evaluated 23 patients with KCNJ11 mutations with (n = 9) and without (n = 14) global developmental delay successfully treated with sulfonylurea and 20 healthy sibling controls, using a battery of targeted neuropsychological and behavioural assessments with scaled scores that are comparable across a wide range of ages. RESULTS: Patients with KCNJ11-related diabetes without global developmental delay had significant differences compared with sibling controls on a range of assessments including IQ, measures of academic achievement and executive function. KCNJ11 patients with global delay exhibited significant differences in behavioural symptoms with a tendency to avoid social contact and displayed a reduced ability to adapt to new circumstances. Parents reported more immature behaviour, gross mood swings, bizarre thoughts, other unusual and severe behaviours, and there were also significant deficits in all subdomains of daily living skills. CONCLUSIONS: This series represents the largest and most comprehensive study of neuropsychological and behavioural dysfunction of individuals with KCNJ11 diabetes and is the first to compare outcome with sibling controls. Our data demonstrate the variety of neurodevelopmental problems seen in those with KCNJ11 mutations, even in those without recognized global developmental delays. These data can be used to counsel families and guide structured neurodevelopmental assessments and treatments based on the initial genetic diagnosis in patients with neonatal diabetes.

Psychiatric morbidity in children with KCNJ11 neonatal diabetes.

AIMS: Mutations in the KCNJ11 gene, which encodes the Kir6.2 subunit of the pancreatic KATP channel, cause neonatal diabetes. KCNJ11 is also expressed in the brain, and ~ 20% of those affected have neurological features, which may include features suggestive of psychiatric disorder. No previous studies have systematically characterized the psychiatric morbidity in people with KCNJ11 neonatal diabetes. We aimed to characterize the types of psychiatric disorders present in children with KCNJ11 mutations, and explore their impact on families. METHODS: The parents and teachers of 10 children with neonatal diabetes due to KCNJ11 mutations completed the Strengths and Difficulties Questionnaire and the Development and Wellbeing Assessment. Strengths and Difficulties Questionnaire scores were compared with normative data. Diagnoses from the Development and Wellbeing Assessment were compared with known clinical diagnoses. RESULTS: Strengths and Difficulties Questionnaire scores indicated high levels of psychopathology and impact. Psychiatric disorder(s) were present in all six children with the V59M or R201C mutation, and the presence of more than one psychiatric disorder was common. Only two children had received a formal clinical diagnosis, with a further one awaiting assessment, and the coexistence of more than one psychiatric disorder had been missed. Neurodevelopmental (attention deficit hyperactivity disorder and autism) and anxiety disorders predominated. CONCLUSIONS: Systematic assessment using standardized validated questionnaires reveals a range of psychiatric morbidity in children with KCNJ11 neonatal diabetes. This is under-recognized clinically and has a significant impact on affected children and their families. An integrated collaborative approach to clinical care is needed to manage the complex needs of people with KCNJ11 neonatal diabetes.

Microcephaly, epilepsy, and neonatal diabetes due to compound heterozygous mutations in IER3IP1: insights into the natural history of a rare disorder.

Neonatal diabetes mellitus is known to have over 20 different monogenic causes. A syndrome of permanent neonatal diabetes along with primary microcephaly with simplified gyral pattern associated with severe infantile epileptic encephalopathy was recently described in two independent reports in which disease-causing homozygous mutations were identified in the immediate early response-3 interacting protein-1 (IER3IP1) gene. We report here an affected male born to a non-consanguineous couple who was noted to have insulin-requiring permanent neonatal diabetes, microcephaly, and generalized seizures. He was also found to have cortical blindness, severe developmental delay and numerous dysmorphic features. He experienced a slow improvement but not abrogation of seizure frequency and severity on numerous anti-epileptic agents. His clinical course was further complicated by recurrent respiratory tract infections and he died at 8 years of age. Whole exome sequencing was performed on DNA from the proband and parents. He was found to be a compound heterozygote with two different mutations in IER3IP1: p.Val21Gly (V21G) and a novel frameshift mutation p.Phe27fsSer*25. IER3IP1 is a highly conserved protein with marked expression in the cerebral cortex and in beta cells. This is the first reported case of compound heterozygous mutations within IER3IP1 resulting in neonatal diabetes. The triad of microcephaly, generalized seizures, and permanent neonatal diabetes should prompt screening for mutations in IER3IP1. As mutations in genes such as NEUROD1 and PTF1A could cause a similar phenotype, next-generation sequencing approaches-such as exome sequencing reported here-may be an efficient means of uncovering a diagnosis in future cases.

Disfagia orofaríngea neurogénica: caracterización clínica y percepción de síntomas en Antioquia, Colombia entre los años 2019 a 2021 / Neurogenic oropharyngeal dysphagia: clinical characterization and perception of symptoms in Antioquia, Colombia between the years 2019 to 2021

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.

En la fase cuantitativa se seleccionaron las orientaciones de acción ubicadas en los Q2 y Q3. Posteriormente se evidenció una validación del protocolo igual a X ̅ =0,98. Conclusiones. Un protocolo de neurorrehabilitación válido ecológicamente se caracteriza por reconocer las percepciones, vivencias y experiencias de familiares y profesionales; recoger evidencia científica confiable; aportar orientaciones y recomendaciones sistémicas para la atención de niñas y niños, y contener criterios de validación de contenido.

Introduction. The human being's development is determined by biological, environmental, and contextual factors that determine the acquisition of neurological skills and that, under pathological situations, increase the risk of alterations in neurodevelopment from early stages. Objective. Design a protocol with ecological validity for the early detection of neurological risk in early childhood by interdisciplinary rehabilitation teams. Methods. A mixed, retrospective, cross-sectional, and descriptive study was performed with Exploratory Sequential Designs (DEXPLOS). In the qualitative phase, two focus groups were formed: one with parents (n=8) and another with professionals (n=6), from which the protocol categories were obtained. In the quantitative phase, scientific articles (n=30) were systematically reviewed to construct the action guidelines. Finally, the protocol was validated by a panel of experts using Aiken's V coefficient. Results. In the qualitative phase, four categories emerged: 1) early detection, 2) development contexts, 3) intervention plan, and 4) quality and humanization of care. In the quantitative phase, the action orientations located in Q2 and Q2 were selected. Subsequently, a validation of the protocol equal to X ̅=0.98 was evidenced. Conclusions. An ecologically valid neuro-rehabilitation protocol is characterized by recognizing the perceptions, expe-riences, and experiences of relatives and professionals; collecting reliable scientific evidence; providing systemic guide-lines and recommendations for the care of girls and boys, and containing content validation criteria.

Structural Brain Alterations in Individuals Post-COVID-19: A Systematic Review / Alteraciones Estructurales Cerebrales en Individuos Post COVID-19: Una Revisión Sistemática

SUMMARY: Although COVID-19 is primarily considered a respiratory pathology, it has been observed to impact other bodily systems, including the nervous system. While several studies have investigated anatomical changes in brain structures, such as volume or thickness post-COVID-19, there are no comprehensive reviews of these changes using imaging techniques for a holistic understanding. The aim of this study was to systematically analyze the literature on brain changes observed through neuroimaging after COVID-19. We conducted a systematic review according to PRISMA guidelines using Web of Science, Scopus, Medline, Pubmed, Sciencedirect, and LitCOVID. We selected studies that included adult patients during or after COVID-19 development, a control group or pre-infection images, and morphometric measurements using neuroimaging. We used the MSQ scale to extract information on sample characteristics, measured anatomical structures, imaging technique, main results, and methodological quality for each study. Out of 1126 identified articles, we included 19 in the review, encompassing 1155 cases and 1284 controls. The results of these studies indicated a lower volume of the olfactory bulb and variable increases or decreases in cortical and limbic structures' volumes and thicknesses. Studies suggest that brain changes occur post-COVID-19, primarily characterized by a smaller olfactory bulb. Additionally, there may be variations in cortical and limbic volumes and thicknesses due to inflammation or neuroplasticity, but these findings are not definitive. These differences may be attributed to methodological, geographical, and temporal variations between studies. Thus, additional studies are required to provide a more comprehensive and quantitative view of the evidence.

Aunque el COVID-19 se considera principalmente una patología respiratoria, se ha observado que afecta otros sistemas corporales, incluido el sistema nervioso. Si bien varios estudios han investigado los cambios anatómicos en las estructuras cerebrales, como el volumen o el grosor posteriores a la COVID-19, no hay revisiones exhaustivas de estos cambios que utilicen técnicas de imágenes para una comprensión holística. El objetivo de este estudio fue analizar sistemáticamente la literature sobre los cambios cerebrales observados a través de neuroimagen después de COVID-19. Realizamos una revisión sistemática de acuerdo con las pautas PRISMA utilizando Web of Science, Scopus, Medline, Pubmed, Sciencedirect y LitCOVID. Seleccionamos estudios que incluyeron pacientes adultos durante o después del desarrollo de COVID-19, un grupo de control o imágenes previas a la infección y mediciones morfométricas mediante neuroimagen. Utilizamos la escala MSQ para extraer información sobre las características de la muestra, las estructuras anatómicas medidas, la técnica de imagen, los principales resultados y la calidad metodológica de cada estudio. De 1126 artículos identificados, incluimos 19 en la revisión, que abarca 1155 casos y 1284 controles. Los resultados de estos estudios indicaron un menor volumen del bulbo olfatorio y aumentos o disminuciones variables en los volúmenes y espesores de las estructuras corticales y límbicas. Los estudios sugieren que los cambios cerebrales ocurren después del COVID-19, caracterizados principalmente por un bulbo olfatorio más pequeño. Además, pueden haber variaciones en los volúmenes y grosores corticales y límbicos debido a la inflamación o la neuroplasticidad, pero estos hallazgos no son definitivos. Estas diferencias pueden atribuirse a variaciones metodológicas, geográficas y temporales entre estudios. Por lo tanto, se requieren estudios adicionales para proporcionar una visión más completa y cuantitativa de la evidencia.

Encefalopatía de Hashimoto. Un diagnóstico por exclusión y revisión de la literatura a partir de un reporte de caso / Hashimoto Encephalopathy as Diagnosis by Exclusion Review of the Literature from a Case Report

La encefalopatía de Hashimoto es una entidad poco frecuente, con una amplia gama de manifestaciones neurológicas que incluyen déficits focales, alteraciones cognitivas, crisis convulsivas, trastorno del movimiento e incluso el coma. Con un curso de la enfermedad de subagudo a fluctuante. Afecta más a mujeres que a hombres, con edad de presentación alrededor de los 44 años, aunque se han reportado casos en la edad pediátrica. De etiología poco clara, se desarrolla en el contexto de la presencia de anticuerpos antitiroideos, independientemente de la función tiroidea. La presencia de estos anticuerpos, sumado a la exclusión de otras etiologías y la respuesta al manejo esteroide son claves para su diagnóstico. Presentamos un caso clínico de una mujer de 57 años de edad que evoluciona con psicosis, alteración del lenguaje, deterioro cognitivo, mioclonías y crisis convulsivas de 5 meses de evolución, quien se excluyó otras causas de demencia rápidamente progresiva con presencia de anticuerpos anti tiroglobulina de 83,6 UI/mL (V.R. < 100 UI/mL) normal y anti tiroperoxidasa en 217 UI/mL (V.R. < 100 UI/mL) elevado. Recibió valoración por el Servicio de Endocrinología, donde se detectó hipotiroidismo y se indicó manejo con levotiroxina sin mejoría del cuadro neurológico. Se indicó manejo esteroide con pulsos de metilprednisona a 500 mg/día por 5 días, con mejoría clínica y se concluyó por criterios de exclusión como una encefalopatía de Hashimoto(AU)

Hashimoto encephalopathy is a rare entity, with wide range of neurological manifestations including focal deficits, cognitive alterations, seizures, movement disorders, and even coma, with a subacute to fluctuating disease course. It affects more women than men, it has age of presentation around 44 years, although cases have been reported in the pediatric age. Its etiology is unclear, it develops in the presence of antithyroid antibodies, regardless of thyroid function. The presence of these antibodies, added to the exclusion of other etiologies and the response to steroid management are key to the diagnosis. We report a clinical case of a 57-year-old woman who evolved with psychosis, language impairment, cognitive impairment, myoclonus, and seizures of 5 month-duration. Other causes of rapidly progressive dementia with the presence of normal antithyroglobulin antibodies of 83.6 IU/mL (RV < 100 IU/mL) and elevated antithyroperoxidase 217 IU/mL (RV < 100 IU/mL) were excluded. She was evaluated in the Endocrinology Department that detected hypothyroidism and indicated management with levothyroxine with no improvement in the neurological condition. Steroid management with methylprednisone pulses at 500 mg/day for 5 days was indicated. Clinical improvement was observed and was concluded to be a Hashimoto encephalopathy by exclusion criteria(AU)

Antiglycolipid autoantibody detected in the sera from systemic lupus erythematosus patients.

A high incidence of autoantibody against the neutral glycolipid "asialo GM1" was observed in sera from patients with systemic lupus erythematosus (SLE) with neurological disorders, using an immunoflocculation test. The sera from 14 out of 17 cases of SLE with neurological disorders showed antibody activity against asialo GM1 but not against the following glycolipids: asialo GM2 GM1, and galactocerebroside. In another 87 cases of SLE without any history of seizures, as well as 61 cases of other autoimmune diseases (rheumatoid arthritis, progressive systemic sclerosis, mixed connective tissue disease, etc.) and 20 cases of various neurological diseases (epilepsy, multiple sclerosis, etc.), no antibody could be detected. In general, the antibody titer was high several months, even years, before and/or after the seizure, though the titer was low at the time that patients showed definite neurological symptoms. Immunochemical characterization with Sephadex G-200 chromatogrphy and protein A-Sepharose CL-4B affinity column indicated that the antiasialo GM1 was probably an autoantibody belonging to the immunoglobulin G class. The above results suggest that this newly found autoantibody plays a role in the pathogenesis of neurological disorders accompanying SLE.

Toxemia of pregnancy in sheep: a clinical, physiological, and pathological study.

Toxemia was induced in 13 of 20 pregnant ewes by the stress of a change in environment and food deprivation late in pregnancy. Of the toxemic ewes, eight developed prominent neurological findings with convulsions, motor weakness, and blindness, whereas five ewes developed azotemia without neurological signs. Proteinuria and azotemia occurred in all but one of the toxemic animals. Seven animals did not develop clinical or laboratory evidence of toxemia. Hypertension did not occur with the onset of toxemia but all toxemic animals showed glomerular changes by light and electron microscopy. These abnormalities, which were similar to those seen in human preeclampsia, included endothelial cell swelling, focal reduplication of the basement membrane, and fusion of the epithelial cell foot processes. The toxemia could not be attributed to changes in hematocrit, plasma glucose, Na, Cl, CO(2), K, Ca, fibrinogen, arterial pH, lactate, or pyruvate concentrations. Cardiac output fell only in ewes with prominent neurological signs. Plasma renin rose strikingly in animals developing toxemia, without change in substrate concentration. In contrast to human and other species, sheep uterus and amniotic fluid contained no detectable quantities of renin. Thus in response to stress the pregnant ewe develops a toxemia which in the absence of hypertension has clinical and pathological similarities to human preeclampsia.

Neurodiagnostic abnormalities in patients with acute renal failure.

Neurological abnormalities are a major cause of morbidity in patients with renal failure. The pathophysiology of these neurological changes is unclear, and the effects on them of dialysis and return of renal function have not been well studied. Studies were done in 31 patients who had acute renal failure (ARF), all of whom were either treated with dialysis within 5 days or did not survive. Studies on these patients included the electroencephalogram (EEG), motor nerve conduction velocity, and plasma Ca(++) and parathyroid hormone (PTH) levels. Studies were done at the time ARF was diagnosed, after stabilization on dialysis, during the diuretic phase of ARF, and 3 mo after recovery from ARF. In 16 patients with acute or chronic renal failure who did not survive and in nine patients without renal disease who died, measurements were made in brain of content of Na(+), K(+), Cl(-), Ca(++), Mg(++), and water. In patients with ARF for less than 48 h, despite the fact that there were only modest increases in plasma urea and creatinine, there were striking abnormalities in the EEG. The percent EEG power < 5 Hz+/-SE was 41+/-8% (normal = 2+/-1%), whereas the percent of frequencies > 9 Hz was only 22+/-6% (normal = 62+/-3%). These changes were unaffected by dialysis, but became normal with return of renal function and remained normal at 3 mo follow-up. The motor nerve conduction velocity was unaffected by either ARF or dialysis. In patients with ARF, the brain Ca(++) was 46.5+/-3.2 meq/kg dry wt, almost twice the normal value of 26.9+/-1.0 meq/kg dry wt (P < 0.001). The plasma PTH level was 3.2+/-0.6 ng/ml (normal < 1.5 ng/ml, P < 0.01). The increased brain Ca(++) was not related to an increased plasma (Ca(++)) (PO(4) (---)) product (r(2) = 0.14, P > 0.05). There was a small but significant decrement in brain Na(+) (P < 0.05), but brain water, K(+), and Mg(++) were unaffected by ARF.Thus, in patients with ARF for less than 48 h, the EEG is grossly abnormal and there are elevated levels of PTH in plasma. The PTH appears to have a direct effect on the brain, resulting in an increased brain Ca(++) content. The EEG abnormalities are unaffected by dialysis, but they become normal with return of renal function and remain normal after 3 mo follow-up. Thus, PTH may be a major uremic toxin, demonstrating evidence for central nervous system toxicity when there are only minimal abnormalities of other biochemical markers of ARF.

Sincronización entre la videodeglución y la electromiografía de superficie en pacientes con afectación neurológica y síntomas de disfagia / Synchronization between videofluoroscopic swallowing study and surface electromyography in patients with neurological involvement presenting symptoms of dysphagia

Introducción. La disfagia se define como la dificultad para movilizar la comida desde la boca hasta el estómago. La prueba diagnóstica para esta condición es la videofluoroscopia, la cual no es totalmente inocua pues utiliza radiación ionizante. La electromiografía de superficie registra la actividad eléctrica de los músculos de manera no invasiva, por lo que puede considerarse como una alternativa para evaluar la deglución y estudiar la disfagia. Objetivo. Evaluar la relación entre los tiempos relativos de activación de los músculos implicados en la fase oral y faríngea de la deglución, con los movimientos registrados durante la videofluoroscopia. Materiales y métodos. Se analizaron las señales de la electromiografía de superficie de 10 pacientes neurológicos con síntomas de disfagia, captadas en forma simultánea con la videofluoroscopia. Se suministraron 5 ml de yogur y 10 ml de agua, y 3 g de galleta. Se estudiaron bilateralmente los grupos musculares maseteros, suprahioideos e infrahioideos. Se analizó el paso del bolo por la línea mandibular, las valleculas y el músculo cricofaríngeo, correlacionándolo con el tiempo inicial y el final de la activación de cada uno de los grupos musculares. Resultados. El tiempo promedio de la fase faríngea fue de 0,89 ± 0,12 s. En la mayoría de los casos, hubo activación muscular antes del paso por la línea mandibular y las valleculas. La terminación de la actividad muscular parece corresponder al momento en que se completa el paso del bolo alimenticio por el músculo cricofaríngeo. Conclusión. Se determinaron los tiempos de actividad muscular, la duración de la fase faríngea y la secuencia de la activación de los grupos musculares involucrados en la deglución, mediante electromiografía de superficie, validada con la videofluoroscopia.

Introduction: Dysphagia is defined as the difficulty in transporting food and liquids from the mouth to the stomach. The gold standard to diagnose this condition is the videofluoroscopic swallowing study. However, it exposes patients to ionizing radiation. Surface electromyography is a non-radioactive alternative for dysphagia evaluation that records muscle electrical activity during swallowing. Objective: To evaluate the relationship between the relative activation times of the muscles involved in the oral and pharyngeal phases of swallowing and the kinematic events detected in the videofluoroscopy. Materials and methods: Electromiographic signals from ten patients with neurological involvement who presented symptoms of dysphagia were analyzed simultaneously with videofluoroscopy. Patients were given 5 ml of yogurt, 10 ml of water, and 3 g of crackers. Masseter, suprahyoid, and infrahyoid muscle groups were studied bilaterally. The bolus transit through the mandibular line, vallecula, and the cricopharyngeus muscle was analyzed in relation to the onset and offset times of each muscle group activation. Results: The average time of the pharyngeal phase was 0.89 ± 0.12 s. Muscle activation was mostly observed prior to the bolus transit through the mandibular line and vallecula. The end of the muscle activity suggested that the passage of the bolus through the cricopharyngeus muscle was almost complete. Conclusion: The muscle activity times, duration of the pharyngeal phase, and sequence of the muscle groups involved in swallowing were determined using sEMG validated with the videofluoroscopic swallowing study.

Mielite transversa por Zika vírus em paciente com Lúpus Eritematoso Sistêmico (LES) - relato de caso em Manaus - AM / Transverse myelitis by Zika virus in patient with Systemic Lupus Erythematosus (SLE) - case report in Manaus - AM

Objetivo: Relatar caso clinico de uma paciente com Mielite Transversa diagnosticada com Lúpus Eritematoso Sistêmico e Zika Vírus. Relato de Caso: Paciente diagnosticada em Lúpus Eritematoso Sistêmico (LES) com nefrite lúpica classe IV há 15 anos em remissão, iniciou quadro de mialgia difusa prejudicando deambulação. Após melhora espontânea do quadro, paciente permaneceu com queixa de astenia e cefaleia intensa unilateral esquerda recorrente, evoluindo com síncope, paraparesia em membro inferior em caráter progressivo ascendente seguido de crise convulsiva tipo tônico clônico generalizado de inicio disruptivo. Um primeiro exame do liquor cefalorraquidiano (LCR) foi solicitado, sem evidência de alteração na analise bioquímica simples. Outras alterações laboratoriais foram identificadas, além do método de reação em cadeia de polimerase (PCR) para Zika vírus na urina e liquor cefalorraquqidiano (após recoleta) detectáveis. Foram detectadas alterações à ressonância magnética compatíveis com mielite transversa. A investigação etiológica durou dois meses e meio, com duas internações no período. Apesar das manifestações neurológicas do Zika Vírus serem ordinariamente inespecíficas, raras e brandas, não se deve desconsiderar a hipótese diagnostica de mielite transversa em área endêmica para arboviroses com manifestações neurológicas mesmo após liquor cefalorraquidiano e outros exames inespecíficos com o achado clínico, considerando paciente remissiva do quadro de lupus eritematoso sistêmico há 15 anos

Objective: case report of a patient with transverse myelitis diagnosed with systemic lupus erythematosus and zika Virus. Case report: Patient diagnosed with Systemic Lupus Erythematosus (SLE) with class IV lupus nephritis for 15 years in remission, begins to have diffuse myalgia, impairing walking. After spontaneous improvement of the condition, the patient remained complaining of asthenia and recurrent left unilateral severe headache, evolving with syncope, progressive ascending paraparesis in the lower limb, followed by a generalized tonic clonic seizure type of disruptive onset. A first examination of the cerebrospinal fluid (CSF) was requested, without evidence of alteration in the simple biochemical analysis. Other laboratory alterations were identified, in addition to the polymerase chain reaction (PCR) for detectable Zika virus in urine and cerebrospinal liquor (after collection). Changes were detected on magnetic resonance imaging (MRI) compatible with transverse myelitis. The etiological investigation lasted two and a half months, with two hospitalizations in the period. Although the neurological manifestations of Zika Virus are ordinarily nonspecific, rare and mild, the diagnostic hypothesis of transverse myelitis in an endemic area for arboviruses with neurological manifestations should not be disregarded even after cerebrospinal fluid and unspecific with the other clinical, remissive of the clinical picture lupus erythemasous systemic 15 years ago.

Guía de valoración pediátrica de urgencias en Cuba / Guide of pediatric emergency assessment in Cuba

La valoración pediátrica de urgencias tiene características especiales respecto al resto de la atención pediátrica. El diagnóstico final será una prioridad secundaria. Es una evaluación clínica, cuyo intento principal es la identificación de aspectos anatómicos y fisiológicos anormales, la estimación de la gravedad de la enfermedad o lesión y la determinación de la necesidad de tratamiento urgente. El objetivo de esta colaboración es brindar una sistemática clara, con una secuencia de valoraciones y acciones que sirvan de base para la toma de decisiones clínicas orientadas a la estabilización del paciente y a evitar situaciones que pueden amenazar la vida en poco tiempo. El triángulo de evaluación pediátrica, la secuencia ABCDE, una breve anamnesis y examen enfocado que identifique el motivo de consulta de mayor prioridad, signos de alarma que pueden cambiar la prioridad y las reevaluaciones frecuentes serán los pilares de la actuación médica. Con el propósito de respetar el derecho del niño al disfrute del más alto nivel posible de salud, de garantizar la calidad asistencial y la seguridad de los pacientes pediátricos con entidades agudas o traumatismos, el grupo nacional de pediatría desarrolló y aprobó la guía de valoración pediátrica de urgencias en Cuba. Mediante la aplicación de esta guía se puede optimizar el proceso de valoración pediátrica de urgencias de forma que los pacientes de este segmento de edad reciban el nivel de cuidados médicos más apropiado para su situación clínica(AU)

The pediatric emergency assessment has special characteristics with respect to the rest of pediatric care. The final diagnosis will be a secondary priority. It is a clinical evaluation, and the main purpose of it is the identification of abnormal anatomical and physiological aspects, the estimation of the severity of the disease or injury and the determination of the need for urgent treatment. The objective of this collaboration is to provide a clear system, with a sequence of assessments and actions that serve as a basis for clinical decision-making aimed at stabilizing the patient and avoiding life-threatening situations in a short time. The pediatric assessment triangle, the ABCDE sequence, a brief history and focused examination that identifies the highest priority reason for consultation, warning signs that may change priority and frequent re-evaluations will be the pillars of medical action. To respect the right of the child to have access to the highest possible level of health, to guarantee the quality of care and its safety in the face of acute conditions or trauma, the National Group of Pediatrics developed and approved the guide for pediatric emergency assessment in Cuba. Through its application, the pediatric emergency evaluation process can be optimized so that patients of this age segment receive the most appropriate level of medical care for their clinical situation(AU)

Principales secuelas neurológicas del COVID-19: una revisión exploratoria / Main neurological sequelae of COVID-19: an exploratory review

El presente trabajo tiene como propósito realizar una revisión sistemática exploratoria que nos permita evidenciar el panorama actual de las distintas secuelas neurológicas ocasionadas por el COVID-19 en los pacientes. Se realizó una búsqueda de la literatura a través de las bases de datos PubMed, Scielo, Medline, Web of Science y Scopus. La búsqueda bibliográfica se llevó a cabo en febrero de 2022. Se identificaron 60 artículos, 10 estaban duplicados y en la fase revisión se excluyeron 9, debido a su diseño metodológico; 2 artículos fueron descartados por incongruencias en la validez de los instrumentos de recolección de datos, por tanto, se utilizaron 39 estudios científicos para la obtención de datos, análisis de resultados y fueron sometidos a evaluación de calidad.

Atendiendo a aspectos metodológicos, el 92,4% son estudios observacionales (descriptivos o de prevalencia analítica o de corte), solamente 3 de ellos (7,6%) se asumen como prospectivos en la direccionalidad del diseño. Se destacan fundamentalmente las siguientes secuelas neurológicas: síndrome neurovascular, encefalopatías, migrañas, ansiedad, depresión, disfunciones olfativas y/o gustativas, sintomatología sensorial, polineuropatía y miopatía, neuralgia y parálisis facial, la fisiopatogénesis de está afectaciones neurologicas, son asociadas pricipalmente al síndrome de respuesta inflamatoria sistemica resultante por la infección con SARS-CoV-2. Se recomienda continuar con investigaciones orientadas a las secuelas por COVID-19, para encauzar el tratamiento y evitar complicaciones graves por esta enfermedad(AU)

The purpose of this study is to carry out an exploratory systematic review that allows us to demonstrate the current panorama of the different neurological sequelae caused by COVID-19 in patients. A literature search was performed through the PubMed, Scielo, Medline, Web of Science and Scopus databases. The bibliographic search was carried out in February 2022. 60 articles were identified, 10 were duplicates and in the review phase 9 were excluded due to their methodological design; 2 articles were discarded due to inconsistencies in the validity of the data collection instruments, therefore, 39 scientific studies were used to obtain data, analyze the results and were subjected to quality evaluation. 33 observational studies, 2 case studies, 3 review articles and 1 meta-analysis were included. Regarding methodological aspects, 92.4% are observational studies (descriptive or analytical or cut-off prevalence), only 3 of them (7.6%) are assumed to be prospective in the directionality of the design. The following neurological sequelae stand out fundamentally: neurovascular syndrome, encephalopathies, migraines, anxiety, depression, olfactory and/or taste dysfunctions, sensory symptomatology, polyneuropathy and myopathy, neuralgia and facial paralysis, the physiopathogenesis of these neurological affections, are mainly associated with the syndrome of systemic inflammatory response resulting from infection with SARS-CoV-2. It is recommended to continue with research aimed at the sequelae of COVID-19, to guide treatment and avoid serious complications from this disease(AU)

Disfonia: retrato de um grupo populacional na cidade de Guarulhos / Dysphonia: portrait of a population group in the city of Guarulhos / Disfonía: retrato de un grupo de población en la ciudad de Guarulhos

Introdução: A disfonia causa impacto na qualidade de vida e no mercado de trabalho, sendo sinto-ma importante para triagem de neoplasia laríngea. Objetivo: Realizar avaliação estatística de um grupo populacional da cidade de Guarulhos com queixa de disfonia. Método: Trata-se de um estudo transversal com utilização de amostra correspondente a 2.564 exames, videolaringoscópicos ou nasofibrolaringoscó-picos, de pacientes acima de 5 anos de idade, no município de Guarulhos da região metropolitana de São Paulo, pelo mesmo médico otorrinolaringologista e pelo mesmo fonoaudiólogo, entre os meses de abril de 2011 e abril de 2012. Avaliaram-se as alterações no diagnóstico da voz, levando em consideração idade e sexo dos pacientes. Foram descritos os sexos das pessoas segundo diagnósticos com uso de frequências absolutas e relativas e verificou-se a existência de associação entre sexo e diagnóstico através do uso de teste da razão de verossimilhanças (Kirkwood e Sterne, 2006). As idades foram descritas, segundo diagnósticos, com uso de medidas resumo (média, desvio-padrão (DP), mediana, mínimo e máximo), e foram comparadas as idades entre os diagnósticos, com uso de teste análise de variâncias (ANOVA) seguido de comparações múltiplas de Tukey (Neter et al., 1996). Os testes foram realizados com nível de significância de 5%. Resultados: Há maior frequência de homens com diagnóstico de neoplasias ou câncer que nos demais diagnósticos. Dos 2.564 exames, 477 apresentaram laringite crônica, sendo 69% do gênero feminino; 279 disfonia funcional, 63,4% do gênero feminino; 137 alterações estruturais míni-mas (AEM), 69,3% do gênero feminino; 36 disfunções neurológicas, sendo igualmente divididos entre os gêneros; e 12 apresentaram neoplasias, sendo 83,3% do masculino. Conclusão: Verificou-se maior número de alterações benignas no gênero feminino. Neoplasias e disfunções neurológicas predominaram no gênero masculino. A disfonia funcional e as AEM ocorrem em pacientes abaixo dos 40 anos, enquanto as demais ocorrem até em idades avançadas, acima dos 50 anos.

Introduction: Dysphonia impacts in quality of life and in the labor market, being an important symptom for screening laryngeal neoplasia. Objective: Perform a statistical evaluation of a population group in the city of Guarulhos complaining of dysphonia. Method: This is a cross-sectional study using a sample corresponding to 2,564 examinations, videolaryngoscopic or nasofibrolaryngoscopic, of pa-tients over 5 years of age, in the municipality of Guarulhos of the metropolitan region of São Paulo, by the same ENT physician and the same speech therapist, between April 2011 and April 2012. Changes in voice diagnosis were evaluated taking into account the age and gender of the patient. The sex of subjects was described according to diagnoses using absolute and relative frequencies, and the existence of an association between sex and diagnosis was verified through the use of likelihood ratio testing (Kirkwood and Sterne, 2006). Ages were described according to diagnoses using summary measurements (mean, standard deviation, median, minimum and maximum), and compared the ages between diagnoses, using variance analysis (ANOVA) followed by multiple comparisons by Tukey (Neter et al., 1996). The tests were performed with a significance level of 5%. Results: There is a higher frequency of men diagnosed with neoplasms or cancer than in other diagnoses. Of the 2,564 tests, 477 had chronic laryngitis, 69% in females; 279 functional dysphonia, 63.4% female; 137 minimal structural alterations (AEM), 69.3% female; 36 neurological dysfunctions, being equally divided between genders; and 12 presented neoplasms, 83.3% in males. Conclusion: There were a higher number of benign alterations in the female gender. Neoplasms and neurological dysfunctions predominated in males. Functional dysphonia and AEM occur in patients under 40 years of age, while the others occur even at advanced ages, above 50 years of age.

Introducción: La disfonía impacta en la calidad de vida y en el mercado laboral, siendo un sínto-ma importante para el cribado de la neoplasia laríngea. Objetivo: Realizar una evaluación estadística de un grupo poblacional de la ciudad de Guarulhos que se queja de disfonía. Método: Se trata de un estudio transversal que utiliza una muestra correspondiente a 2564 exámenes, videolaringoscópicos o nasofibrolaringoscópicos, de pacientes mayores de 5 años, en el municipio de Guarulhos de la región metropolitana de São Paulo, realizados por el mismo otorrinolaringólogo y el mismo logopeda, entre abril de 2011 y abril de 2012. Los cambios en el diagnóstico de voz se evaluaron teniendo en cuenta la edad y el sexo de las personas. Los sexos de las personas se describieron de acuerdo con los diagnósticos utilizando frecuencias absolutas y relativas, y la existencia de una asociación entre el sexo y el diagnóstico se verificó mediante el uso de pruebas de razón de probabilidad (Kirkwood y Sterne, 2006). Las edades se describieron de acuerdo con los diagnósticos utilizando mediciones resumidas (media, desviación estándar, mediana, mínima y máxima), y se compararon las edades entre los diagnósticos, utilizando el análisis de varianza (ANOVA) seguido de comparaciones múltiples de Tukey (Neter et al., 1996). Las pruebas se realizaron con un nivel de significancia del 5%. Resultados: Hay una mayor frecuencia de hombres diagnosticados con neoplasias o cáncer que en otros diagnósticos. De las 2.564 pruebas, 477 presentaban laringitis crónica, el 69% en mujeres; 279 disfonía funcional, el 63,4% mujeres; 137 alteraciones estructurales mínimas (AEM), el 69,3% mujeres; 36 disfunciones neurológicas, estando divididas por igual entre géneros; y 12 presentaban neoplasias, el 83,3% en varones. Conclusión: Hubo un mayor número de alteraciones benignas en el género femenino. Las neoplasias y las disfunciones neurológicas predominaron en los varones. La disfonía funcional y la AEM ocurren en pacientes menores de 40 años de edad, mientras que las otras ocurren incluso a edades avanzadas, por encima de los 50 años de edad.

El síndrome respiratorio agudo severo causado por coronavirus 2 (SARS-CoV-2) es responsable de la propagación mundial de la enfermedad por coronavirus (COVID-19). Nuestro conocimiento hasta el momento del impacto de este virus en el sistema nervioso es limitado. El propósito de este artículo es revisar el espectro de los diversos hallazgos en neuroimágenes asi como la fisiopatología en los pacientes con COVID-19. Se necesitan estudios futuros que examinen el impacto de los síntomas y su correlación con las neuroimágenes durante el curso de la enfermedad, para aclarar y evaluar aún más el vínculo entre las complicaciones neurológicas y el resultado clínico, así como limitar las consecuencias a largo plazo.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the global spread of coronavirus disease (COVID-19). Our understanding, so far, of the impact this virus has on the nervous system is limited. Our article aims to review the spectrum of neuroimaging findings in patients with COVID 19, as well as, their underlying pathophysiology. Future studies examining the impact of symptoms and their correlation with neuroimaging findings duirng the course of the disease are needed to further clarify and evaluate the association between neurological complications and clinical outcome, as well as to limit long-term consequences.

Manifestaciones neurológicas en una paciente con lupus eritematoso sistémico / Neurological manifestations in a patient with systemic lupus erythematosus

El lupus eritematoso sistémico es una enfermedad inflamatoria sistémica cuyo proceso inflamatorio genera un importante número de manifestaciones clínicas articulares y extraarticulares. Entre las manifestaciones extraarticulares destaca la afectación neurológica, y el compromiso puede ser tanto a nivel del sistema nervioso central o periférico. El objetivo de la presente investigación es presentar el caso de una paciente de 56 años de edad, con diagnóstico de lupus eritematoso sistémico de 18 años de evolución quien presentó un cuadro crónico de cefalea, neuropatía periférica y miastenia gravis como manifestaciones neurológicas de la enfermedad. Con el tratamiento de ciclofosfamida y el aumento de la dosis de esteroide, en la actualidad la paciente se encuentra estable. El reporte de este caso hace hincapié en la importancia que revisten las manifestaciones neurológicas como parte de las manifestaciones extraarticulares de esta enfermedad, ya que este tipo de afección es determinante en el curso del lupus eritematoso sistémico y en la calidad de vida de los pacientes(AU)

Systemic lupus erythematosus is a systemic inflammatory disease whose inflammatory process generates a significant number of articular and extra-articular clinical manifestations. Within the extra-articular manifestations, neurological involvement stands out, among others, the commitment can be both at the level of the central or peripheral nervous system. The objective of the present investigation is to present the case of a 56-year-old patient, diagnosed with systemic lupus erythematosus of 18 years of evolution and who has presented chronic symptoms of headache, peripheral neuropathy and myasthenia gravis as neurological manifestations of the illness. The report of this case is considered important to publicize the importance of neurological manifestations as part of the extra-articular manifestations of this disease; this type of condition is decisive in the course of the disease and in the quality of life of patients(AU)
