ABSTRACT

El accidente apídico implica un bajo riesgo de morir por reacciones agudas como anafilaxia. Es frecuente que se desconozcan otros riesgos como el hepático y el neurológico. Dentro de las complicaciones menos conocidas está la polineuropatía aguda conocida como Guillain- Barré. La causa más ampliamente descrita es la reacción cruzada entre IgE y la proteína básica de mielina. A continuación, se reporta el primer caso en América Latina sobre la asociación entre Guillain-Barré y accidente por picadura de abejas. En este caso, hay criterios de causalidad como el nexo temporal, la plausibilidad biológica y la coherencia con otros artículos reportados en la literatura médica.


Bee sting accident usually implies a low risk of dying from acute reactions such as anaphylaxis. Other risks such as liver and neurological risks are often unknown. Among the lesser-known complications caused by this type of accident is the acute polyneuropathy known as Guillain-Barré. The most widely described cause is the cross reaction between IgE and myelin basic protein. The article reports the first case in Latin America on the association between Guillain-Barré and a bee sting accident. In this case, there are causality criteria such as temporal link, biological plausibility, and consistency with other articles reported in the medical literature

ABSTRACT

Introducción: La debilidad adquirida en la unidad de cuidados intensivos (DAUCI) compromete tanto a los músculos de las extremidades como el diafragma, asociándose con variables de resultado negativas. El objetivo del estudio fue describir las características epidemiológicas e incidencia de DAUCI en adultos con requerimiento de ventilación mecánica invasiva (VMI) mayor a 72 horas en un Hospital General de Agudos de la Ciudad de Buenos Aires. Método: Estudio de cohorte retrospectivo. Se incluyeron pacientes adultos con requerimiento de VMI por más de 72 horas en la Unidad de Cuidados Intensivos (UCI). Las principales variables de interés registradas fueron: incidencia de DAUCI, días de VMI, estadía y mortalidad tanto en UCI como hospitalaria. Resultados: Se incluyeron 262 pacientes de los cuales 87 (33,21%) intercurrieron con debilidad. No se establecieron diferencias estadísticamente significativas entre los pacientes con y sin DAUCI para las variables edad, motivo de ingreso a VMI, número de antecedentes personales y mortalidad tanto en UCI como hospitalaria. En el presente estudio se establecieron como factores de riesgo independiente al sexo femenino (OR: 1,98; IC 95%: 1,02 ­3,81), delirio (OR 8,4; IC 95%: 4,38-16,11) y días de VMI (OR: 1,05; IC 95%: 1,02-1,08). Conclusiones: El presente estudio nos permitió conocer la incidencia y las características epidemiológicas de los pacientes que presentan DAUCI en una UCI del sistema público de salud de Argentina. Se observó que el sexo femenino, los días de VMI y el delirio en UCI fueron factores de riesgo independiente para DAUCI.

ABSTRACT

Introduction: Intensive care unit-acquired weakness (ICUAW) affects the muscles of the limbs and diaphragm; and is associated with negative outcome variables. The purpose of this study was to describe the epidemiological characteristics and incidence of ICUAW in adults requiring invasive mechanical ventilation (IMV) for more than 72 hours in a General Hospital for Acute Diseases in the City of Buenos Aires. Method: Retrospective cohort study. We included adult patients requiring IMV for more than 72 hours in the Intensive Care Unit (ICU). The main recorded variables of interest were: incidence of ICUAW, days of IMV, length of stay and mortality both in the ICU and in the hospital. Results: 262 patients were included in the study; 87 of them (33.21%) developed weakness. No statistically significant differences were established between patients with and without ICUAW regarding the variables of age, reason for admission to IMV, medical history and mortality both in the ICU and the hospital. In this study, the variables established as independent risk factors were: female gender (OR: 1,98; 95% CI: 1.02-3.81), delirium (OR 8.4; 95% CI: 4.38-16.11) and days of IMV (OR: 1.05; 95% CI: 1.02-1.08). Conclusions: This study allowed us to know the incidence and epidemiological characteristics of patients with ICUAW in an ICU of the public health system of Argentina. It was observed that female gender, days of IMV and delirium at the ICU were independent risk factors for ICUAW.

ABSTRACT

RESUMO: Modelo do Estudo: Relato de caso. Importância do problema: No mundo, mais de três milhões de pessoas estão vivendo com deficiência física devido à hanseníase. O Brasil é o segundo país com o maior número de casos novos registrados.A magnitude e o alto risco de incapacidade mantêm a doença como problema de saúde pública. O diagnóstico de hanseníase em geral é simples. Porém, quadros com ausência de lesões cutâneas características, somente com alterações neurais, representam um desafio para o diagnóstico diferencial com outras doenças neurológicas. Comentários: Relatamos o caso de um paciente encaminhado ao serviço de neurologia com história clínica e eletroneuromiografia compatíveis com polineuropatia desmielinizante, sem qualquer lesão cutânea ao exame de admissão. O raciocínio clínico inicial foi direcionado para o diagnóstico das polineuropatias desmielinizantes inflamatórias adquiridas como Polineuropatia Desmielinizante Inflamatória Crônica (CIDP) e suas variantes. No entanto, após anamnese e exame físico detalhados, chamou a atenção a ausência do componente atáxico e a presença predominante de alterações sensitivas de fibra fina, espessamento de nervo e importante fator epidemiológico para hanseníase, motivando a suspeita e a in-vestigação desta enfermidade por meio da biópsia de nervo que foi sugestiva de hanseníase. Após três meses, em novo exame do paciente para biopsiar áreas de anestesia para reforçar o diagnóstico, observou-se o surgimento de extensas lesões levemente hipocrômicas no tronco e membros inferiores, cuja biópsia definiu o diagnóstico de hanseníase.

ABSTRACT: Study: Case report. Importance: Worldwide over three million people are living with disabilities due to leprosy. Brazil is the second country with the highest number of new cases registered. The magnitude and high risk of disability make the disease a public health problem. The diagnosis of leprosy can be simple. However, in the absence of skin lesions and with many possibilities of neurological impairment, diagnosis can become a challenge. Comments: We report the case of a patient referred to the neurology service with a clinical history and electrophysiological tests compatible with demyelinating polyneuropathy, without any skin lesion at admission examination. The initial clinical research was directed to the diagnosis of acquired inflammatory demyelinating polyneuropathies such as Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)and its variants. However, after anamnesis and detailed physical examination, the absence of the ataxic component and the predominant presence of sensory alterations of fine fiber, nerve thickening and important epidemiological factor for leprosy,led to the suspicion and investigation of this disease by nerve biopsy that was suggestive of leprosy. After three months, in a new patient examination "to perform a biopsy in areas of anesthesia" to reinforce the diagnosis, there was the appearance of extensive slightly hypochromic lesions in the trunk and lower limbs, whose biopsy defined the diagnosis of leprosy.(AU)

ABSTRACT

Se describe el caso de una mujer de 35 años que presenta polineuropatía desmielinizante inflamatoria crónica como compromiso neurológico en su diagnóstico inicial de lupus eritematoso sistémico (LES). Si bien el compromiso neurológico es de una prevalencia variable en lupus, la asociación que se describe no es frecuente y tiene importantes connotaciones en el tratamiento.


We described a 35 years old female, who developed Chronic inflammatory demyelinating polyneuropathy as neurologic commitment during the early diagnosis in Systemic Lupus Erithematosus (SLE). While the neuropsychiatric commitment has a variable prevalence in SLE, the association that we describe is infrequent and it has important concerns during its treatment.

ABSTRACT

El síndrome de Guillain-Barré constituye una entidad de etiología diversa, que se caracteriza por debilidad muscular aguda, simétrica, ascendente y progresiva, y es una de las polineuropatías adquiridas más frecuentes en la infancia. Entre los diagnósticos diferenciales, deben considerarse las neuropatías producidas por metales pesados, mercurio y plomo, y metaloides, como el arsénico, plaguicidas organofosforados y el tetracloruro de carbono.Se presenta a un paciente de 14 años con diagnóstico de síndrome de Guillain-Barré sin respuesta al tratamiento convencional con gammaglobulina. Considerando otras etiologías, se sospechó neuropatía producida por metales pesados, y se confirmó intoxicación por mercurio.El objetivo de esta presentación es concientizar a los pediatras acerca del impacto de los tóxicos ambientales en la salud infantil para realizar un diagnóstico precoz pesquisando datos clave a través de la historia clínica ambiental


Guillain-Barré syndrome is an entity of diverse etiology, characterized by acute, symmetric, ascending and progressive muscle weakness, being one of the most frequent acquired polyneuropathies in childhood. Neuropathies produced by heavy metals, mercury and lead, and metalloids, such as arsenic, organophosphorus pesticides and carbon tetrachloride, should be considered among the differential diagnoses.We present a 14-year-old patient with a presumptive diagnosis of Guillain-Barré syndrome without response to conventional treatment with gamma globulin. Considering other etiologies, heavy metal neuropathy was suspected, and mercury poisoning was confirmed.The aim of this presentation is to make pediatricians aware about the impact of environmental toxic agents on children's health in order to make an early diagnosis by researching key data through the environmental clinical history.

ABSTRACT

BACKGROUND@#Multifocal motor neuropathy (MMN), Lewis-Sumner syndrome (LSS), and many chronic inflammatory demyelinating polyradiculoneuropathies (CIDPs) are representative of acquired multifocal polyneuropathy and are characterized by conduction block (CB). This retrospective study aimed to investigate the demyelinating distribution and the selective vulnerability of MMN, LSS, and CIDP with CB (CIDP-CB) in nerves.@*METHODS@#Fifteen LSS subjects (107 nerves), 24 MMN subjects (176 nerves), and 17 CIDP-CB subjects (110 nerves) were included. Their clinical information was recorded, blood and cerebrospinal fluid tests were conducted, and nerve conductions of the median, ulnar, radial, peroneal, and tibial nerves were evaluated. CB, temporal dispersion, distal motor latency (DML), and F-wave latency were recorded, and nerve conduction velocity, terminal latency index, and modified F-wave ratio were calculated.@*RESULTS@#CB was more likely to occur around the elbow in CIDP-CB than in MMN (78.6% vs. 6.8%, P < 0.01) but less likely to occur between the wrist and the elbow than in LSS (10.7% vs. 39.3%, P < 0.05). Tibial nerve CB was most frequently observed in MMN (47.4%, P < 0.05). CIDP-CB was characterized by a prolonged DML in all nerves, and slow motor nerve velocity of the upper limb was significant when CB nerves were excluded (P < 0.05).@*CONCLUSIONS@#We report the different distributions of segmental and diffuse demyelination of the ulnar and tibial nerves in LSS, MMN, and CIDP-CB. These distinct distributions could help in differentiating among these conditions.

ABSTRACT

Introducción:el síndrome de Guillain-Barré (SGB) es una polineurorradiculopatía desmielinizante aguda inmunomediada. El síntoma principal es la debilidad muscular. El objetivo del presente estudio es describir las características del episodio agudo, las secuelas neurológicas a largo plazo y cómo estas afectan la situación laboral y las actividades de tiempo libre. Materiales y métodos: estudio realizado en dos fases: primera, descripción retrospectiva de casos; segunda, corte transversal donde se interrogaron las secuelas neurológicas y sus implicaciones. Resultados: se identificaron 63 casos de SGB con edad promedio de 50,79 años (DE 17.8), más frecuente en hombres (61,9%) y cuyo promedio de la escala Hughes en el episodio agudo fue 3,2 (DE ± 10,1). Las principales complicaciones durante la fase aguda fueron neumonía (7,94 %) y úlceras por presión (3,17 %). Se logró contactar vía telefónica a 28 pacientes, 82,1% presentó al menos un síntoma como secuela, 60,7% parestesias, 57,1% fatiga, 50% calambres y 46,4% dolor de características neuropáticas. El 32,1% tuvo cambios o retiro de su trabajo por las secuelas; 21,43% debió modificar sus actividades de tiempo libre. Conclusión: existe alta prevalencia de síntomas residuales discapacitantes después del episodio agudo de SGB con predominio de síntomas sensitivos, coincidiendo con estudios realizados en países desarrollados. Estas alteraciones ocasionan un impacto negativo en la actividad laboral y en la de tiempo libre de los pacientes.


Introduction: Guillain-Barré syndrome (GBS) is an acute immune-mediated demyelinating polyneuropathy. The main symptom encountered is muscle weakness. This study seeks to describe the characteristics of an acute episode, the long-term neurologic sequelae and how they affect patients ́ work and leisure activities. Materials and Methods: a two-phase study comprising a retrospective case description in the first phase followed by a cross sectional study during the second phase in which patients were asked to describe their neurologic sequelae and how they affected them Results: we identified 63 cases of GBS, mean age was 50.79 years (SD 17.8), there was a male preponderance (61.9%) with a 3.2 (SD ± 10.1) average score on the Hughes scale during the acute episode. Major complications during the acute phase were pneumonia (7.94 %) and pressure sores (3.17 %). Phone contact was achieved with 28 patients, 82.1% presented at least one sequelae 60.7% paresthesia, 57.1% fatigue, 50% cramps and 46.4% neuropathic pain.

ABSTRACT

Resumen Introducción: El artículo reporta un caso clínico de intento suicida de un paciente con síndrome intermedio a causa de intoxicación por organofosforados. Para ello se analizó la historia clínica, los exámenes complementarlos y el estudio electromiográflco, y se realizó revisión no sistemática de la literatura. Presentación del caso: Se describe un caso diagnosticado en la unidad de cuidado intensivo, el cual presentó trastornos neuromotores, requerimiento de soporte ventilatorio con destete difícil y extubación fallida, así como el tratamiento médico y fisioterapéutico instaurado. Dentro del manejo de la intoxicación por organo-fosforados se incluye la descontaminación del tóxico, administración de atropina y pralidoxima, diagnóstico oportuno del síndrome intermedio y la prescripción de ejercicio terapéutico. El paciente recibió manejo interdisciplinario, logrando liberación de su condición crítica, pero con persistencia de debilidad muscular proximal; sin embargo, con el ejercicio alcanzó recuperación funcional de sus actividades básicas cotidianas. Conclusión: El panorama mundial de las intoxicaciones por sustancias químicas muestra que son causa de morbilidad y discapacidad importante. Los organofosforados son los plaguicidas más frecuentemente involucrados. Los síntomas y signos clínicos de este tipo de intoxicaciones se clasifican en manifestaciones colinérgicas, el síndrome intermedio y la neuropatía retardada.


Abstract Introduction: The article reports a clinical case of a suicide attempt of a patient with intermediate syndrome due to organophosphate poisoning. Researchers analyzed the clinical history and the complementary examinations and carried out an electro-myographic study and a non-systematic review of the literature. Case presentation: A diagnosed case is described in the unit of intensive care, which presented neuro-motor disorders, required ventilator support with difficult weaning and unsuccessful extubation, as well as the established medical and physiotherapeutic treatment. The management of organophosphate poisoning includes the decontamination of the toxic, the administration of atropine and pralidoxime, the diagnosis of the intermediate syndrome, and the prescription of therapeutic exercise. The patient received interdisciplinary management, achieving liberation from his critical condition but with the persistence of proximal muscular weakness; however, with the exercise, he accomplished functional recovery for basic daily activities. Conclusion: The global outlook of chemical substances poisoning shows that they are a cause of morbidity and significant disability. The organophosphates are the pesticides most frequently involved. The symptoms and the clinical signs of this type of intoxication are classified into cholinergic manifestations, intermediate syndrome, and delayed neuropathy.

ABSTRACT

ABSTRACT Objective: To determine the sensitivity and specificity of peripheral and respiratory muscle strength tests in diagnosing critical illness polyneuromyopathy (CIPNM), compared with an electrophysiological examination. Methods: Fifty septic patients who required mechanical ventilation for at least five days, and without a previous history of muscle weakness, were included. Peripheral muscle strength was assessed using the Medical Research Council (MRC) score, handgrip strength by dynamometry, and respiratory muscle strength with maximum respiratory pressures. Diagnosis of CIPNM was either confirmed or rejected by an electrophysiological examination. Receiver operating characteristic curve analysis was performed to determine the cut-off values with the best sensitivity (SN) and specificity (SP) of the studied variables in the presence or absence of CIPNM. Results: Patients with CIPNM were older, more critical (APACHE IV/SAPS 3), had a longer hospitalization, required mechanical ventilation for longer, and had a higher rate of intensive care unit readmission. Cutoff values identified CIPNM patients using MRC scores, dynamometry according to sex, maximal expiratory and inspiratory pressures, as well as being confirmed by the electrophysiological examination, with good sensitivity and specificity: < 40 (SN: 0.893; SP: 0.955); < 7 kg (SN: 1; SP: 0.909) for men, < 4 kg (SN: 0.882; SP: 1) for women; < 34 cmH2O (SN: 0.808; SP: 0.909) and > −40 cmH2O (SN: 0.846; SP: 0.909), respectively. Conclusion: The MRC score, dynamometry or maximum respiratory pressures can be used to identify patients with CIPNM at the intensive care bedside assessment. The healthcare professional can choose any of the methods studied to evaluate the patient, based on his experience and the resource available.


RESUMO Objetivo: Determinar a sensibilidade (SN) e especificidade (SP) dos testes de força muscular periférica e respiratória no diagnóstico da Polineuromiopatia do Doente Crítico (PNDC) em comparação com o estudo eletrofisiológico. Métodos: Foram incluídos 50 pacientes sépticos, em ventilação mecânica (VM) durante pelo menos cinco dias e sem história prévia de fraqueza muscular. A força muscular foi avaliada utilizando o escore Medical Research Council (MRC), a força de preensão palmar e as pressões respiratórias máximas. O diagnóstico de PNDC foi confirmado ou excluído pelo estudo eletrofisiológico. A análise da curva ROC foi realizada para determinar os valores de corte com a melhor SN e SP. Resultados: Os pacientes com PNDC eram mais velhos, mais graves, tiveram hospitalização mais longa, necessitaram de VM por mais tempo e apresentaram maior taxa de readmissão na Unidade de Terapia Intensiva. Os valores de corte identificaram os pacientes com PNDC usando o MRC, a dinamometria de acordo com o sexo, as pressões expiratórias e inspiratórias máximas, também confirmado pelo estudo eletrofisiológico, com boa sensibilidade e especificidade: < 40 (SN: 0.893; SP: 0.955), < 7 kg (SN: 1; SP: 0,909) para homens, < 4 kg (SN: 0,882; SP: 1) para mulheres, <34 cmH2O (SN: 0,808; SP: 0,909) e > −40 cmH2O (SN: 0,846; SP: 0,909), respectivamente. Conclusão: Tanto o MRC, a dinamometria quanto as pressões respiratórias máximas podem ser usadas para identificar pacientes com PNDC na avaliação à beira do leito, podendo o profissional de saúde escolher qualquer um dos métodos baseado em sua experiência e no recurso disponível.

ABSTRACT

BACKGROUND AND PURPOSE: Tafamidis functions to delay the loss of function in transthyretin familial amyloid polyneuropathy (TTR-FAP), which is a rare inherited amyloidosis with progressive sensorimotor and autonomic polyneuropathy. This systematic literature review and meta-analysis evaluated the efficacy and safety of tafamidis in TTR-FAP patients, with the aim of improving the evidence-based medical evidence of this treatment option for TTP-FAP. METHODS: A systematic search of the English-language literature in five databases was performed through to May 31, 2018 by two reviewers who independently extracted data and assessed the risk of bias. We extracted efficacy and safety outcomes and performed a meta-analysis. Statistical tests were performed to check for heterogeneity and publication bias. RESULTS: The meta-analysis identified six relevant studies. The tafamidis group showed smaller changes from baseline in the Neuropathy Impairment Score–Lower Limbs [mean difference (MD)=−3.01, 95% confidence interval (CI)=−3.26 to −2.75, p < 0.001] and the Norfolk Quality of Life-Diabetic Neuropathy total quality of life score (MD=−6.67, 95% CI=−9.70 to −3.64, p < 0.001), and a higher modified body mass index (MD=72.45, 95% CI=69.41 to 75.49, p < 0.001), with no significant difference in total adverse events [odds ratio (OR)=0.69, 95% CI=0.35 to 1.35, p=0.27]. The incidence of adverse events did not differ between tafamidis and placebo treatment except for fatigue (OR=0.13, 95% CI=0.02 to 0.72, p=0.02) and hypesthesia (OR=0.16, 95% CI=0.03 to 0.92, p=0.04). CONCLUSIONS: This systematic review and meta-analysis has demonstrated that tafamidis delays neurologic progression and preserves a better nutritional status and the quality of life. The rates of adverse events did not differ between the patients in the tafamidis and placebo groups. Tafamidis might be a safer noninvasive option for patients with TTR-FAP.

ABSTRACT

POEMS syndrome is a rare paraneoplastic syndrome, which includes polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes due to plasma cell (PC) neoplasm. Diagnosis of this disease is challenging because of its rarity and complex clinical manifestations. We attempted to identify the key clinical features and characteristic bone marrow (BM) findings of POEMS syndrome, by reviewing the medical records and BM analyses of 24 Korean patients. Frequent clinical manifestations included polyneuropathy (100%), monoclonal gammopathy (100%), organomegaly (92%), extravascular volume overload (79%), and endocrinopathy (63%). The BM analyses revealed mild PC hyperplasia (median PCs: 5.5%) and frequent megakaryocytic hyperplasia (88%), megakaryocyte clusters (88%), and hyperlobation (100%). Flow cytometry of BM aspirates using CD138/CD38/CD45/CD19/CD56 showed normal (67%, 4/6) or neoplastic PC immunophenotypes (33%, 2/6). A diagnosis of POEMS syndrome must be considered when a patient suspected of having PC dyscrasia shows the above clinical presentation and BM findings.

ABSTRACT

We report two cases of subacute combined degeneration (SCD) caused by nitrous oxide (N₂O) gas intoxication, which is rarely reported in Korea. Two patients recreationally inhaled N₂O gas daily for several months. They presented with paresthesia of limbs, voiding difficulty, and gait disturbance. The initial vitamin B₁₂ levels were normal or decreased, but homocysteine levels of the two patients were increased. Magnetic resonance imaging of the cervical spine showed T2-weighted hyperintensity in the bilateral dorsal columns of the cervical spinal cord. Electromyography and somatosensory evoked potential tests for both patients suggested posterior column lesion of the spinal cord combined with sensorimotor polyneuropathy. According to these findings, we concluded that the two patients had SCD. The patient’s symptoms partially improved after cessation of N₂O gas inhalation and the receiving of vitamin B₁₂ supplementation therapy. As the incidence of recreational N₂O gas inhalation is increasing in Korea, physicians must be alert to the N₂O induced SCD in patients presenting with progressive myelopathy.

ABSTRACT

Swallowing can be affected by a variety of systemic diseases. The etiology of dysphagia in the geriatric population is usually overlooked due mainly to a presumed diagnosis of presbyphagia or difficulty in revealing the direct cause. On the other hand, dysphagia can be a meaningful clinical sign of premalignant systemic disease. A 78-year-old man, without any prior medical or family history, was admitted with the chief complaint of dysphagia with recent aspiration pneumonia. Instrumental swallowing tests revealed a severe degree of dysphagia due to decreased laryngopharyngeal sensation and weakness of the pharyngeal constrictor muscles. Extensive workup, including electromyography and laboratory tests, revealed severe sensorimotor peripheral polyneuropathy related to monoclonal gammopathy. Monoclonal gammopathy of undetermined significance (MGUS) is a premalignant precursor of multiple myeloma, which is characterized by the proliferation of monoclonal proteins. These conditions are often associated with peripheral polyneuropathy, ataxia, and sometimes even muscle weakness. Although dysphagia can occur in other systemic disorders, such as vasculitis or paraneoplastic syndrome-related malignancies, there are few reports of dysphagia related to MGUS. The patient was followed up for three years. The MGUS showed no further progression, but the patient showed no improvement, indicating a protracted clinical course and poor prognosis when dysphagia is related to MGUS.

ABSTRACT

Unexplained pain and weakness, i.e., without obvious predisposing factors, are often encountered by physiatrists and efforts should be made to determine the cause. A 63-year-old male presented with radiating pain in his right arm and mild weakness of the right hand. An electrodiagnostic examination revealed distal symmetric sensory polyneuropathy in the upper and lower extremities, and denervation potentials in the forearm muscles, which were inconsistent with the cervical spine MRI images and symptoms. A predisposing undiscovered disease was revealed, i.e., squamous cell carcinoma in the lung; brain metastasis affecting the left primary motor cortex was also detected. Therefore, we concluded that the pain and weakness were related to paraneoplastic syndrome and brain metastases of the hand knob. The observed denervation potentials were characterized as trans-synaptic changes in the brain metastasis. This case highlights the importance of unexplainable focal pain and weakness in the increasing prevalence of cancer.

ABSTRACT

This article provides an overview for understanding the classification and pathogenesis of diabetic neuropathy. Diabetic neuropathies are prevalent disorder. The most common manifestation is distal symmetric polyneuropathy, but various patterns of neuropathy can occur. New information for the pathogenesis of diabetic neuropathy continues to emerge, which will lead to identifying new drug targets.

ABSTRACT

The most prevalent microvascular complication of diabetes mellitus is neuropathy, which encompasses distal symmetric polyneuropathy, mononeuropathy, radiculoplexopathy, and autonomic neuropathy. Intensive glucose control prevents and effectively halts the progression of diabetic neuropathy in patients with type 1 diabetes mellitus. However, the effect of strict glucose control itself is at modest in those with type 2 diabetes. Although we have better understanding of the mechanism of diabetic neuropathy, many pharmacologic trials for the targeting underlying nerve damage have reported unsuccessful results. In this review, the effects and limitations of the current therapeutic options will be discussed.
