Behavior of neuropathy symptom score and neuropathy disability score in patients with and without peripheral diabetic neuropathy: A retrospective cohort study.

BACKGROUND: This study aimed to stablish cut-off of early diagnosis of diabetic polyneuropathy (PDN) based on neuropathy symptom score (NSS) and neuropathy disability score (NDS); to determine the behavior of NDD and NDS in patients with and without PDN; and to verify the association between clinical and demographic variables with both tests. METHODS: This retrospective cohort included 86 patients with diabetes. The NSS and NDS evaluations were collected in medical records in two moments: initial (entry into service) and final (after three years). Individuals were categorized in three groups: G1- PDN in both evaluations (N = 27); G2- PDN only in the final evaluation (N = 16); G3-individuals without PDN (N = 43). A ROC curve was performed to evaluate the sensitivity and specificity of NSS and NDS for PDN diagnosis. ANOVA was used to compare NSS and NDS between groups and evaluations, and multiple regression was performed to find predictors of PDN. RESULTS: The NSS and NDS showed excellent sensitivity and specificity (NDS ≥1.5 and NSS ≥6.5) for PDN diagnosis. There was a significant difference between groups in initial (p = 0.000) and final (p = 0.000) NDS and NSS evaluations. There was an association between peripheral arterial disease (PAD) and increase in NSS (p = 0.024) in G2; and association between loss of protective sensation (LOPS) and increase in NSS in G3 (p < 0.001). CONCLUSION: NSS and NDS tests showed excellent sensitivity and specificity for early PDN diagnosis. Behavior of both tests can differ patients with and without PDN. Furthermore, PAD and LOPS can be a predictor of PDN evolution.

Multiple sclerosis starting before the age of 18 years: the Brazilian experience.

Multiple sclerosis (MS) starting in childhood and adolescence poses a challenge for diagnosis and management of the disease. The aim of the present study was to assess the characteristics of early onset MS in Brazilian patients. Methods Retrospective data collection from specialized MS units. Results From 20 MS units in 11 Brazilian states, 117 cases of MS starting before the age of 18 years were collected. These patients had an average of 10 years of disease duration, still typically with low disability and one relapse every 2.5 years. The mean age for disease onset was 13.7 years. Conclusion The present study introduces a large series of Brazilian cases of pediatric MS. Although some patients presented a very severe form of MS, on the whole the group of patients with MS starting in childhood or adolescence presented a relatively mild form of this disease in Brazil.

Esclerose múltipla (EM) com início na infância e adolescência constitui um desafio para o diagnóstico e manejo da doença. A proposta do presente estudo foi avaliar as características da EM de início precoce em pacientes brasileiros. Métodos Coleta de dados retrospectiva de arquivos de unidades especializadas em atendimento da EM. Resultados A partir de 20 unidades de EM de nove estados brasileiros, foram coletados 117 casos de EM com início antes dos 18 anos de idade. Estes pacientes tinham uma média de 10 anos de duração da doença, de maneira geral apresentavam pouca incapacidade , com um surto a cada dois anos e meio. A média de idade no início da doença era 13,7 anos. Conclusão O presente estudo apresenta uma grande série de casos brasileiros de EM pediátrica. Embora alguns pacientes tenham apresentado forma grave de EM, de maneira geral o grupo de pacientes cuja EM iniciou-se na infância ou adolescência apresentou uma forma relativamente leve da doença no Brasil. .
