RESUMO
Non-arteritic anterior ischemic optic neuropathy (NAION) is after glaucoma the most common optic neuropathy in patients over 50 years. It is known that high blood pressure (HBP) is an important risk factor for the development of NAION. It is also known that malignant arterial hypertension (MAH) could be accompanied by optic disc edema. However, MAH has not classically been considered a cause of NAION. We report the case of a 32-year-old patient who presented irreversible visual loss with a pattern compatible with NAION as the only manifestation of a hypertensive crisis.
RESUMO
El estudio de la regularidad de la Frecuencia Cardiaca, a través del Holter de 24 horas se hace desde la década de los años 60 y es bastante efectivo. Sin embargo, desde los años noventa comenzaron a efectuarse estudios cortos de Holter en pacientes sospechados de tener fallas autonómicas de control de la frecuencia cardiaca, especialmente en pacientes con comorbilidades tales como Hipertensión, Diabetes Mellitus, Aterosclerosis etc. De aquí la importancia de realizar un test de Holter de diez minutos, divididos en dos tiempos de 5 minutos, primero en decúbito dorsal y luego en bipedestación, especialmente en pacientes de más de cincuenta años o con comorbilidades presentes. Los resultados se presentan luego en gráficos de Poincare, que incluye el programa operativo del dispositivo, que permite un vistazo de la elipse con sus dos ejes, que representan las acciones simpáticas y parasimpáticas sobre la frecuencia cardiaca. Una variabilidad anormal de la frecuencia cardiaca debe ser luego estudiada más profundamente a fin de reafirmar el diagnóstico y ulteriores pasos en el tratamiento.
The variability of Cardiac Frequency is a valuable monitor of the autonomic function and is currently used as tool for study of changes of regularity through Holter 24 hours. From nighties, several researchers have been oriented to stablish relationship between VCF and autonomic failure, especially in patients with comorbidities, such as Hypertension, Diabetes Mellitus, atherosclerosis etc. Actually is well known that a lost or VCF or a minor variability, even in short traces of Holter in 10 minutes, means an autonomic failure, of baroreflex and quimioreflex resources. Hence, the importance of performing test of ten minutes Holter, five in decubitus position and five in standing, to patients of more than fifty years old, or less if comorbidities are presents, to design a Poincare diagram, which is special to indicate in quick view the prevalence of Sympathetic o Vagal action on cardiac frequency; that conduces to a more deep study of Autonomic failure, such tilt test, extended holter of 24 hours, and others medicals images resources.
RESUMO
Progressive Supranuclear Palsy (PSP), also known as Steele-Richardson-Olszewski syndrome, is a rare neurodegenerative disease characterized by a variety of motor and neuro-ophthalmological symptoms. We present the case of a 73-year-old male patient with a history of type 2 diabetes and high blood pressure, who consulted for gait disorders, tremors in the extremities, and difficulty controlling conjugate gaze. During physical examination, findings consistent with PSP were noted, including hypomimia, muscle rigidity, and abnormal movements. The initial misdiagnosis of Parkinson's disease and subsequent administration of levodopa highlight the importance of accurate diagnosis in complex neurological conditions. This clinical case highlights the need for a thorough evaluation of neuro-ophthalmological symptoms and signs to ensure an appropriate therapeutic approach and improve the quality of life of patients.

Fluoroquinolones (FQs) are one of the most commonly prescribed classes of antibiotics. Although they were initially well tolerated in randomized clinical trials, subsequent epidemiological studies have reported an increased risk of threatening, severe, long-lasting, disabling and irreversible adverse effects (AEs), related to neurotoxicity and collagen degradation, such as tendonitis, Achilles tendon rupture, aortic aneurysm, and retinal detachment. This article reviews the main potentially threatening AEs, the alarms issued by regulatory agencies and therapeutic alternatives. (AU)
Las fluoroquinolonas son una de las clases de antibióticos más prescritas. Aunque inicialmente fueron bien toleradas en ensayos clínicos aleatorizados, estudios epidemiológicos posteriores han informado de un mayor riesgo de efectos adversos efectos adversos amenazantes, graves, duraderos, incapacitantes e irreversibles, relacionados con la neurotoxicidad y la degradación del colágeno, como tendinitis, rotura del tendón de Aquiles, aneurisma aórtico y desprendimiento de retina. Este artículo repasa los principales efectos adversos potencialmente amenazadores, las alarmas emitidas por las agencias reguladoras y las alternativas terapéuticas. (AU)

BACKGROUND: Diabetic peripheral neuropathy (DPN) is the most dominant cause of neuropathy worldwide, and there has been no specific treatment until now. The aim of the current study was to assess the probable protective effect of empagliflozin in type 2 diabetics who are suffering from DPN. METHODS: Fifty eligible type 2 diabetes mellitus (T2DM) cases with diabetic peripheral neuropathy were recruited in this study and classified into 2 groups. Group I (n=25) (control group) received placebo tablets once daily. Group II (n=25) (empagliflozin group) received empagliflozin 25mg once daily for three months. Empagliflozin efficacy was evaluated using electrophysiological studies, and HbA1c levels, the brief pain inventory short-form item (BPI-SF) score, the diabetic neuropathy symptom (DNS) score, the atherosclerotic cardiovascular disease (ASCVD) risk score, and the serum levels of neuron-specific enolase (NSE), malondialdehyde (MDA) and calprotectin (Calpro), lipid profile, and random blood glucose level (RBG). RESULTS: After three months, comparing the results of the empagliflozin arm to the control arm showed a significant improvement in the electrophysiological studies and a significant decrease in the BPI-SF score and the mean serum levels of NSE and MDA. However, no significant difference was determined in HbA1c, Calpro, lipid profile, and RBG levels. In addition, the DNS and ASCVD risk scores were not significantly different. The NSE and MDA levels were significantly negatively correlated with the electrophysiological parameters. However, the BPI-SF score showed a non-significant difference. CONCLUSIONS: Empagliflozin may be a promising neuroprotective and therapeutic agent for diabetic peripheral neuropathy. Trial registration Identifier: NCT05977465.

INTRODUCTION: Charcot-Marie-Tooth disease (CMT) is classified according to neurophysiological and histological findings, the inheritance pattern, and the underlying genetic defect. The objective of these guidelines is to offer recommendations for the diagnosis, prognosis, follow-up, and treatment of this disease in Spain. MATERIAL AND METHODS: These consensus guidelines were developed through collaboration by a multidisciplinary panel encompassing a broad group of experts on the subject, including neurologists, paediatric neurologists, geneticists, physiatrists, and orthopaedic surgeons. RECOMMENDATIONS: The diagnosis of CMT is clinical, with patients usually presenting a common or classical phenotype. Clinical assessment should be followed by an appropriate neurophysiological study; specific recommendations are established for the parameters that should be included. Genetic diagnosis should be approached sequentially; once PMP22 duplication has been ruled out, if appropriate, a next-generation sequencing study should be considered, taking into account the limitations of the available techniques. To date, no pharmacological disease-modifying treatment is available, but symptomatic management, guided by a multidiciplinary team, is important, as is proper rehabilitation and orthopaedic management. The latter should be initiated early to identify and improve the patient's functional deficits, and should include individualised exercise guidelines, orthotic adaptation, and assessment of conservative surgeries such as tendon transfer. The follow-up of patients with CMT is exclusively clinical, and ancillary testing is not necessary in routine clinical practice.

RESUMEN A partir de una revisión bibliográfica de la literatura se ha planeado y desarrollado un consenso de expertos internacionales sobre la utilización de las vitaminas B1, B6, B12 en sus déficits y en la neuropatía periférica que puede estar asociada a la misma, como tema que precia de esa aproximación aclaratoria para optimizar su manejo. Se plantearon varias cuestiones de discusión que se consideraron importantes y dignas de ser abordadas y aclaradas, conservando nueve de ellas para su discusión ulterior buscando el consenso en tres rondas consecutivas. Se han propuesto 41 recomendaciones sobre el manejo de estas condiciones, con unanimidad por parte de los participantes en el consenso. Con ellas se ha intentado aclarar puntos oscuros o controvertidos, facilitando la actitud del clínico ante ellos en la práctica médica actual.
ABSTRACT Based on a bibliographic review of the literature, a consensus of international experts has been carried out on the use of vitamins B1, B6, B12, in their deficiencies, and in the peripheral neuropathy that may be associated with them, to optimize the management of these conditions. Several questions considered important and worthy of being addressed and clarified were raised, retaining nine of them for further discussion to achieve consensus. Forty one recommendations on the management of these conditions have been proposed, with unanimity of the participants in the consensus. This has been an attempt to clarify controversial points, assisting the clinician's attitude in current medical practice.
RESUMO
ABSTRACT A 71-year-old woman presented a non-arteritic anterior ischemic optic neuropathy in an optic nerve with previously registered superonasal peripapillary myelinated nerve fibers. Her past medical history was significant for controlled systemic hypertension, hyperlipidemia, and diabetes mellitus. The physiologic cup was absent in both optic discs. Non-arteritic anterior ischemic optic neuropathy mainly affected the temporal and inferior sectors of the peripapillary retinal nerve fiber layer, as could be demonstrated by retinal nerve fiber layer optical coherence tomography and optic disc optical coherence tomography angiography. Unlike other published reports, just a slight regression of the myelinated nerve fibers was observed after 1 year of follow-up. This occurred because ischemia mainly affected the temporal and inferior peripapillary sectors, whereas myelinated nerve fibers were superonasal to the optic disc.
RESUMO Uma mulher de 71 anos de idade apresentou neuropatia óptica isquêmica anterior não arterítica no nervo óptico com fibras nervosas peripapilares mielinizadas previamente registradas. Seu histórico médico foi significativo para hipertensão arterial sistêmica controlada, hiperlipidemia e diabetes mellitus. Em ambos os discos ópticos, a tacícula fisiológica esteve ausente. A neuropatia óptica isquêmica anterior não arterítica afetou principalmente os setores temporal e inferior da camada de fibras nervosas da retina peripapilar, como demonstrado pela tomografia de coerência óptica da camada de fibras nervosas da retina e pela angiotomografia de coerência óptica do disco óptico. Ao contrário de outros relatórios publicados, apenas uma ligeira regressão das fibras nervosas mielinizadas foi observada após um ano de acompanhamento. Isto pode ser explicado pelo fato da isquemia ter afetado principalmente os setores temporal e inferior peripapilares, enquanto as fibras nervosas de mielina eram nasal superior ao disco óptico.
RESUMO
Abstract Background Patients with anti-MAG neuropathy present with distal demyelinating polyneuropathy, IgM monoclonal gammopathy, and elevated titers of anti-MAG antibodies. Objective This paper reviews what is known about the clinical presentation, course, pathophysiology, and treatment of anti-MAG neuropathy, with considerations for the design of therapeutic trials. Methods A literature review of the medical and scientific literature related to anti-MAG neuropathy, and the design of therapeutic clinical trials in peripheral neuropathy. Results Anti-MAG neuropathy can remain indolent for many years but then enter a progressive phase. Highly elevated antibody titers are diagnostic, but intermediate titers can also occur in chronic inflammatory demyelinating polyneuropathy (CIDP). The peripheral nerves can become inexcitable, thereby masking the demyelinating abnormalities. There is good evidence that the anti-MAG antibodies cause neuropathy. Reduction of the autoantibody concentration by agents that target B-cells was reported to result in clinical improvement in case series and uncontrolled trials, but not in controlled clinical trials, probably due to inadequate trial design. Conclusion We propose that therapeutic trials for anti-MAG neuropathy include patients with the typical presentation, some degree of weakness, highly elevated anti-MAG antibody titers, and at least one nerve exhibiting demyelinating range abnormalities. Treatment with one or a combination of anti-B-cell agents would aim at reducing the autoantibody concentration by at least 60%. A trial duration of 2 years may be required to show efficacy. The neuropathy impairment score of the lower extremities (NIS-LL) plus the Lower Limb Function (LLF) score would be a suitable primary outcome measure.
Resumo Antecedentes Pacientes com neuropatia anti-MAG apresentam polineuropatia desmielinizante distal, gamopatia monoclonal IgM e títulos elevados de anticorpos anti-MAG. Objetivo Este artigo revisa o que se sabe sobre a apresentação clínica, curso, fisiopatologia e tratamento da neuropatia anti-MAG, com considerações para o desenho de ensaios terapêuticos. Métodos Revisão bibliográfica da literatura médica e científica relacionada à neuropatia anti-MAG e desenho de ensaios clínicos terapêuticos em neuropatia periférica. Resultados A neuropatia anti-MAG pode permanecer indolente durante muitos anos, mas depois entra numa fase progressiva. Títulos de anticorpos altamente elevados são diagnósticos, mas títulos intermediários também podem ocorrer na polineuropatia desmielinizante inflamatória crônica (CIDP). Os nervos periféricos podem tornar-se inexcitáveis, mascarando, assim, as anomalias desmielinizantes. Há boas evidências de que os anticorpos anti-MAG causam a neuropatia. Foi relatado que a redução da concentração de autoanticorpos por agentes direcionados às células B resultou em melhora clínica em séries de casos e ensaios não controlados, mas não em ensaios clínicos controlados, provavelmente devido ao desenho inadequado dos ensaios. Conclusão Propomos que os ensaios terapêuticos para neuropatia anti-MAG incluam pacientes com apresentação típica, algum grau de fraqueza, títulos de anticorpos anti-MAG altamente elevados e pelo menos um nervo exibindo anormalidades na faixa desmielinizante. O tratamento com um ou uma combinação de agentes anticélulas B teria como objetivo reduzir a concentração de autoanticorpos em pelo menos 60%. Pode ser necessária uma duração de ensaio de 2 anos para demonstrar eficácia. A pontuação de comprometimento da neuropatia das extremidades inferiores (NIS-LL) mais a pontuação da função dos membros inferiores (LLF) seria uma medida de resultado primário adequada.
RESUMO
Abstract Lipomas are the most common soft-tissue tumors in the human body, but their location in the hand is rare. Symptomatic hand lipomas, due to nerve compression, are even rarer. We present a case of median nerve neuropathy as a result of a giant palm lipoma, located on the thenar and hypothenar areas of the hand. The patient had typical symptoms of carpal tunnel syndrome, along with compromised thumb motion. Intraoperatively, the recurrent motor branch of the median nerve was sitting on the lipoma under a great tension. This particular location of the motor branch of the median nerve in relation to the lipoma makes this case unique. The tumor was excised protecting the neurovascular structures, and a few weeks later the patient regained full thumb motion, grip strength, and resolution of dysesthesia.
Resumo Os lipomas são os tumores de partes moles mais comuns no corpo humano, mas sua localização na mão é rara. Os lipomas de mão que causam sintomas por compressão do nervo são ainda mais raros. Apresentamos um caso de neuropatia do nervo mediano decorrente de um lipoma palmar gigante, localizado nas regiões tenar e hipotenar da mão. A paciente apresentava sintomas típicos de síndrome do túnel do carpo, além de comprometimento dos movimentos do polegar. Durante a cirurgia, o ramo motor recorrente do nervo mediano repousava sobre o lipoma sob grande tensão. Esta localização particular do ramo motor do nervo mediano em relação ao lipoma torna este caso único. O tumor foi extirpado, protegendo as estruturas neurovasculares e, poucas semanas depois, a paciente havia recuperado totalmente os movimentos do polegar e força de preensão, além de apresentar resolução da disestesia.

La amiloidosis siempre ha representado un desafío diagnóstico. En el año 2020, el Grupo de Estudio de Amiloidosis (GEA), confeccionó la Guía de Práctica Clínica para el Diagnóstico de Amiloidosis. Nuevas líneas de investigación se han desarrollado posteriormente. Esta revisión narrativa tiene como intención explorar el estado del arte en el diagnóstico de la amiloidosis. En pacientes con amiloidosis se recomienda la tipificación de la proteína mediante espectrometría de masa, técnica de difícil ejecución por requerir de microdisectores láser para la preparación de la muestra. Algunas publicaciones recientes proponen otros métodos para obtener la muestra de amiloide que se va a analizar, permitiendo prescindir de la microdisección. Por otra parte, en pacientes con Amiloidosis ATTR confirmada, la recomendación de secuenciar el gen amiloidogénico se encontraba destinada a los casos sospechosos de ATTR hereditaria (ATTRv,), pero actualmente esta se ha extendido a todos los pacientes sin importar la edad. En lo que respecta a los estudios complementarios orientados al diagnóstico de compromiso cardíaco, se ha propuesto el uso de la inteligencia artificial para su interpretación, permitiendo la detección temprana de la enfermedad y el correcto diagnóstico diferencial. Para el diagnóstico de neuropatía, las últimas publicaciones proponen el uso de la cadena ligera de neurofilamento sérica, que también podría resultar un indicador útil para seguimiento. Finalmente, con referencia a la amiloidosis AL, la comunidad científica se encuentra interesada en definir qué características determinan el carácter amiloidogénico de las cadenas livianas. La N-glicosilación de dichas proteínas impresiona ser uno de los determinantes en cuestión. (AU)
Amyloidosis has always represented a diagnostic challenge. In 2020, the Amyloidosis Study Group (ASG) developed the "Clinical Practice Guideline for the Diagnosis of Amyloidosis". New lines of research have subsequently emerged. This narrative review aims to explore the state of the art in the diagnosis of amyloidosis diagnosis. In patients with amyloidosis, protein typing by mass spectrometry is recommended, a technique hard to perform because it requires laser microdissection for sample preparation. Recent publications propose other methods to obtain the amyloid sample to be analyzed, making it possible to dispense with microdissection. On the other hand, in patients with confirmed TTR amyloidosis (aTTR), the recommendation to sequence the amyloidogenic gene was intended for suspected cases of hereditary aTTR but has now been extended to all patients regardless of age.

RESUMEN Objetivo: Describir las actitudes de los médicos hacia el abordaje de la neuropatía diabética. Métodos: Estudio descriptivo, observacional, transversal y prospectivo, muestra 143 médicos, muestreo no probabilístico por conveniencia. Las variables: años de ejercicio profesional, especialidad, proporción de pacientes en la consulta médica con diagnóstico de diabetes mellitus (tipo 1 o 2), proporción de pacientes con diabetes mellitus con diagnóstico de neuropatía diabética, actitudes hacia el abordaje de la neuropatía diabética. Se empleó escala Likert de 5 categorías para evaluar actitudes en 3 dimensiones: priorización, diagnóstico y tratamiento. Se emplearon estadísticos descriptivos. Resultados: En la dimensión priorización el 57.4% prioriza el control metabólico sobre la evaluación de complicaciones. Dimensión diagnostico el 80.5% de médicos encuestados se basan en síntomas y signos referidos por el paciente para hacer el diagnóstico de dicha complicación, el 66,5% reconocen que no usan instrumento para la evaluación de la neuropatía y el 39.9% tampoco lo usarían así lo tuviera. En la dimensión tratamiento el 73,5% reconocen que el tratamiento analgésico de la neuropatía diabética es frustrante y el 50,4% siente "temor" para titular la dosis de la medicación analgésica anti-neuropática por los efectos adversos. Conclusiones: Las actitudes de los médicos comprometen diferentes áreas del abordaje de la neuropatía diabética como la priorización, el diagnóstico y el tratamiento con una tendencia a la priorización del control metabólico y de otras complicaciones microvasculares, al sub-diagnóstico, al "sub-tratamiento" y a la necesidad de referir a los pacientes para manejo especializado.
ABSTRACT Objective: To describe the attitudes of doctors towards the approach to diabetic neuropathy. Methods: Descriptive, observational, cross-sectional and prospective study, sample of 143 doctors, non-probabilistic convenience sampling. The variables: years of professional practice, specialty, proportion of patients in the medical consultation with a diagnosis of diabetes mellitus (type 1 or 2), proportion of patients with diabetes mellitus with a diagnosis of diabetic neuropathy, attitudes towards the approach to diabetic neuropathy. A 5-category Likert scale was used to evaluate attitudes in 3 dimensions: prioritization, diagnosis and treatment. Descriptive statistics were used. Results: In the prioritization dimension, 57.4% prioritize metabolic control over the evaluation of complications. Diagnostic dimension: 80.5% of doctors surveyed rely on symptoms and signs reported by the patient to make the diagnosis of said complication, 66.5% recognize that they do not use an instrument for the evaluation of neuropathy and 39.9% would not use it either. had it. In the treatment dimension, 73.5% recognize that analgesic treatment for diabetic neuropathy is frustrating and 50.4% feel "afraid" to titrate the dose of anti-neuropathic analgesic medication due to adverse effects. Conclusions: The attitudes of doctors compromise different areas of the approach to diabetic neuropathy such as prioritization, diagnosis and treatment with a tendency to prioritize metabolic control and other microvascular complications, to under-diagnosis, to "under-treatment". " and the need to refer patients for specialized management.
RESUMO
Resumen: La diabetes mellitus, un padecimiento crónico y progresivo, ocupó el tercer lugar en defunciones durante el período comprendido de enero a junio de 2021 en México. Su complicación crónica más frecuente es la neuropatía diabética que tiene un impacto importante en el sistema nervioso. En la Ciudad de México se reunió un grupo multidisciplinario de expertos para establecer un algoritmo de tratamiento que considere los aspectos sintomáticos y etiopatogénicos de la neuropatía diabética. Se utilizó un método Delphi en tiempo real con dos rondas de preguntas interactivas. La implementación del algoritmo propuesto permitirá abordar de manera integral al paciente diabético con neuropatía dolorosa y no dolorosa, tanto en el terreno de los síntomas como en la etiopatogenia. Este abordaje brinda la oportunidad de mejorar la calidad de vida y lograr la reinserción a la vida familiar y laboral. El panel de expertos recomienda al ácido tióctico como tratamiento etiopatogénico de primera línea en la neuropatía diabética.
Abstract: Diabetes mellitus, a chronic and progressive condition, was the third most common cause of death in Mexico between January and June 2021. Its most frequent chronic complication is diabetic neuropathy, which has a major impact on the nervous system. A multidisciplinary group of experts met in Mexico City to establish a treatment algorithm considering the symptomatic and etiopathogenic aspects of diabetic neuropathy. A real-time Delphi method with two rounds of interative questions was used. The implementation of the proposed algorithm will allow a comprehensive approach to the diabetic patient with painful and non-painful neuropathy, both in terms of symptoms and etiopathogenesis. This approach provides the opportunity to improve quality of life and achieve reintegration into family and work life. The expert panel recommends thioctic acid as the first line etiopathogenic treatment for diabetic neuropathy.
RESUMO
Abstract Supracondylar apophysis (SA) is a bony prominence that originates from the anteromedial aspect of the distal humerus with a lower projection and which, although usually asymptomatic, due to the relationship with adjacent structures can cause symptoms. We describe the case of a 42-year-old woman with pain complaints radiating from her elbow to her hand, with 6 months of evolution. On objective examination, the patient had a sensory deficit in the median nerve territory and decreased grip strength. Radiographs of the distal humerus were performed, in which a bone spike was visible, and magnetic resonance imaging showed thickening of the median nerve epineurium. Electromyography showed severe axonal demyelination of the median nerve proximal to the elbow. A median nerve compression caused by a SA was diagnosed. The patient underwent surgery and, 1 year after the operation, she had a complete clinical recovery. Supracondylar apophysis is a rare, but possible and treatable cause of high median nerve compression.
Resumo A apófise supracondilar (ASC) é uma proeminência óssea que tem origem na face anteromedial do úmero distal com projeção inferior e que, apesar de habitualmente assintomática, pela relação com as estruturas adjacentes pode causar sintomatologia. Descrevemos o caso de uma mulher de 42 anos, com queixas álgicas irradiadas do cotovelo à mão, com 6 meses de evolução. Ao exame objetivo, a paciente apresentava um déficit sensorial no território do nervo mediano e diminuição da força de preensão. Foram realizadas radiografias do úmero distal nas quais era visível uma espícula óssea, e na ressonância magnética era evidente o espessamento do epineuro do nervo mediano. A eletromiografia apresentou uma desmielinização axonal grave do nervo mediano proximal ao cotovelo. Foi diagnosticada uma compressão do nervo mediano por uma ASC. A paciente foi submetida à cirurgia e 1 ano pós-operatório apresentou recuperação clínica total. A ASC é uma causa rara, mas possível e tratável da compressão alta do nervo mediano.

Introducción: El glaucoma es una de las enfermedades oculares de mayor prevalencia a escala mundial y se caracteriza por presión intraocular elevada, cambios en la papila y alteraciones en el campo visual. Objetivo: Caracterizar a pacientes con glaucoma crónico simple según variables epidemiológicas y clínicas. Método: Se realizó un estudio observacional, descriptivo y transversal de 96 pacientes con glaucoma primario de ángulo abierto, quienes fueron atendidos en la consulta de oftalmología del Policlínico Docente Alberto Fernández Montes de Oca del municipio de San Luis, en la provincia de Santiago de Cuba, desde enero hasta julio del 2019. Resultados: En la serie prevalecieron el sexo masculino, el grupo etario de 60 a 69 años y los pacientes de piel negra, además de la hipertensión arterial y ocular como factores de riesgo asociados. Por otra parte, la mayoría de los afectados presentaron agudeza visual entre 1,0-0,6, cifras de presión intraocular entre 16-21 mmHg y excavación papilar entre 0,6-0,7, con daños importantes en el campo visual. Conclusiones: Las características epidemiológicas y clínicas de los pacientes con glaucoma primario de ángulo abierto resultaron útiles para establecer el pronóstico y trazar pautas terapéuticas efectivas, a fin de evitar la fase avanzada de la enfermedad y los daños irreversibles que se producen en el nervio óptico.
Introduction: Glaucoma is one of the most prevalent eye diseases worldwide and is characterized by high intraocular pressure, changes in the papilla and visual field alterations. Objective: To characterize patients with chronic simple glaucoma according to epidemiologic and clinical variables. Methods: An observational, descriptive and cross-sectional study of 96 patients with primary open-angle glaucoma was carried out, who were assisted in the Ophthalmology Service of Alberto Fernández Montes de Oca Teaching Polyclinic of San Luis municipality, in Santiago de Cuba province, from January to July, 2019. Results: In the series there was a prevalence of the male sex, the 60 to 69 age group, and dark-skinned patients, besides hypertension and ocular hypertension as associated risk factors. On the other hand, most of those affected presented visual acuteness between 1.0-0.6, intraocular pressure figures between 16-21 mmHg and papillary excavation between 0.6-0.7, with important damage in the visual field. Conclusions: The epidemiologic and clinical characteristics of patients with primary open-angle glaucoma were useful to establish the prognosis and trace effective therapeutic guidelines, in order to avoid the advanced phase of the disease and the irreversible damage that occurs in the optic nerve.

Introduction: the diabetic foot is one of the most serious complications of diabetes mellitus. About 50% of non-traumatic amputations occur in these patients. In addition, it is an important public health problem and constitutes a chronic and complex metabolic disorder that is characterized by impaired metabolism of glucose and other complications in essential organs for the maintenance of life. Objective: to evaluate the sensitivity and specificity of diabetic neuropathy using the Michigan self-assessment and physical examination in type 1 and type 2 diabetics. Methods: this is a cross-sectional study. The "Michigan Neuropathy Screening Instruments" classification was used to assess the degree of peripheral neuropathy, in which participants answered the questionnaire and were evaluated for the presence of foot lesions. All participants were stratified by the risk of developing foot ulcers according to the IWGDF protocol. Results: the sample had 200 participants. Regarding the IWGDF classification, 23 patients were classified as moderate risk (11.50%) and 61 as high risk for developing foot ulcers (30.50%). Using a cutoff of 2.5 on the physical examination score to diagnose neuropathy, a sensitivity of 97.62% and a specificity of 47.41% were obtained. Using a score greater than or equal to 6 in the self-assessment for the diagnosis of neuropathy, a sensitivity of 50.00% and a specificity of 94.83% were found. Conclusion: the association of the Michigan physical examination (high sensitivity) with self-assessment (high specificity) increases the accuracy for the diagnosis of diabetic neuropathy
Introdução: o pé diabético é uma das complicações mais sérias do diabetes mellitus. Cerca de 50% das amputações não traumáticas ocorrem nesses pacientes. Além disso, é um importante problema de saúde pública por ser um distúrbio metabólico crônico e complexo que se caracteriza pelo comprometimento do metabolismo da glicose associada a outras complicações em órgãos essenciais para manutenção vital. Objetivo: avaliar a sensibilidade e especificidade para neuropatia diabética da autoavaliação e do exame físico de Michigan nos diabéticos tipo 1 e tipo 2. Método: trata-se de um estudo transversal. Foi utilizada a classificação "Michigan Neuropathy Screening Instruments" para avaliação do grau de neuropatia periférica, em que os participantes responderam ao questionário e foram avaliados quanto a presença de lesões nos pés. Todos os participantes foram estratificados quanto ao risco de desenvolver úlcera nos pés de acordo com o protocolo do IWGDF. Resultados: a amostra contou com 200 participantes. Quanto à classificação do IWGDF, 23 pacientes foram classificados como risco moderado (11,50%) e 61 como alto risco para o desenvolvimento de úlceras nos pés (30,50%). Utilizando-se um corte de 2,5 na pontuação do exame físico para diagnosticar a neuropatia, foi obtida uma sensibilidade de 97,62% e uma especificidade de 47,41%. Utilizando-se uma pontuação maior ou igual a 6 na autoavaliação para o diagnóstico de neuropatia, foi obtida uma sensibilidade de 50,00% e uma especificidade de 94,83%. Conclusão: a associação do exame físico de Michigan (alta sensibilidade) com a autoavaliação (alta especificidade) tem melhor acurácia para o diagnóstico de neuropatia diabética.
RESUMO
Introducción: La neuropatía diabética es la complicación más frecuente de la diabetes mellitus y una de sus posibles consecuencias es el síndrome del pie diabético. Los médicos del primer nivel de atención deben conocer el comportamiento clínico de la neuropatía diabética y, sobre todo, como influye en la aparición y desarrollo del síndrome del pie diabético. Objetivo: Describir el papel de la neuropatía diabética en la aparición y desarrollo del síndrome del pie diabético. Métodos: Para la obtención de la información se utilizaron como motores de búsqueda de información científica los correspondientes a Scielo, Pubmed, y Google Académico. Se usaron como palabras clave: diabetes mellitus; neuropatía diabética; pie diabético; síndrome de pie diabético; úlcera de pie diabético; ataque de pie diabético. Se evaluaron diferentes trabajos de revisión, investigación y páginas web, y se excluyeron los artículos que tuvieran más de 10 años de publicados, en idiomas diferentes al español, portugués e inglés y que no se refirieran al tema de estudio a través del título. Esto permitió la cita de 45 referencias bibliográficas. Conclusiones: La neuropatía diabética constituye el principal factor de riesgo en la aparición y desarrollo del síndrome del pie diabético, sobre todo cuando se asocia a artropatía (defectos podálicos), enfermedad vascular periférica y/o sepsis. El control de la glucemia, la detección temprana del pie de riesgo y el cuidado preventivo de los miembros inferiores, repercutirá favorablemente en la salud y bienestar del paciente(AU)
Introduction: Diabetic neuropathy is the most frequent complication of diabetes mellitus and one of its possible consequences is diabetic foot syndrome. First level of care physicians should know the clinical behavior of diabetic neuropathy and, above all, how it influences the appearance and development of diabetic foot syndrome. Objective: To describe the role of diabetic neuropathy in the appearance and development of diabetic foot syndrome. Methods: To obtain the information, SciELO, PubMed and Google Scholar were used as search engines for scientific information. The keywords used were: diabetes mellitus; diabetic neuropathy; diabetic foot; diabetic foot syndrome; diabetic foot ulcer; diabetic foot attack. Different review papers, research papers and web pages were evaluated and articles that were more than 10 years old and published in languages other than Spanish, Portuguese and English and that did not refer to the subject of the study through the title were excluded. This allowed the citation of 45 bibliographic references. Conclusions: Diabetic neuropathy constitutes the main risk factor in the appearance and development of diabetic foot syndrome, especially when associated with arthropathy (foot defects), peripheral vascular disease and/or sepsis. Glycemic control, early detection of the foot at risk and preventive care of the lower limbs will have a favorable impact on the patient's health and well-being(AU)

Defined as the unpleasant sensation that causes the desire to scratch, pruritus is the most common skin symptom associated with uremia and appears in almost half of patients with advanced chronic kidney disease (CKD). Beyond its direct impact on quality of life, CKD-associated pruritus (CKD-aP) is an independent predictor of mortality that also has a synergistic effect with other quality of life-related symptoms, such as insomnia, depression, and anxiety. Although different mechanisms have been proposed to explain the origin of Pa-ERC, its etiopathogenesis is still not fully understood. Since new therapeutic targets have been identified and several clinical trials have recently shown promising results, our current understanding of the interrelationships has expanded significantly and the pathophysiological mechanisms underlying CKD-aP are now considered to be multifactorial. The potential triggers of pruritus in patients with CKD are discussed in this review, including hypotheses about skin xerosis, accumulation of uremic toxins, dysregulation of the immune system and systemic inflammation, uremic neuropathy, and imbalances in the endogenous opioid system. Other non-uremic causes of pruritus are also discussed, with the aim of guiding the physicians to apply an adequate aetiopathogenic approach to CKD-aP in their day-to-day clinical practice.
