Sensory disturbance and polyneuropathy in rheumatoid arthritis patients with foot deformity / Perturbações sensitivas e polineuropatia em pacientes com artrite reumatoide com deformidade do pé

Abstract Introduction Our aim in this study was to present the results of sensory evaluation tests and electrophysiological evaluations in rheumatoid arthritis (RA) patients with foot deformity and to determine their relation with general health status and lower extremity functionality. Materials and methods Fifty-one patients with RA diagnosis and foot deformity were included in the study. Demographic and disease characteristics of the patients were recorded, and a detailed neurological examination was performed. Superficial sensation, pain, heat, vibration, and two-point discrimination sensation were evaluated in each foot, and their sum was used to determine the sensory deficits index (SDI) of 0–10. The presence of polyneuropathy was evaluated with electrophysiological methods. The Health Assessment Questionnaire and mobility and walking subscales of the Arthritis Impact Measurement Scales-2 were used to assess general health status and lower extremity functionality, respectively. According to the sensory examination and electromyography results, patients were compared in terms of their general health status and lower extremity functional status. Results Sensory disturbance was detected in 39 patients (74%) during the examination; however, 27 patients (52.9%) had polyneuropathy determined electrophysiologically. In patients with sensory deficits, statistically significant deterioration was detected in general health and foot functionality, including mobility and walking, when compared to patients with a normal sensory evaluation. Conclusions Even in the presence of normal electrophysiological tests, sensory dysfunction alone seems to be associated with severe disability in general health status and foot functionality when compared to patients with a normal sensory examination.

Resumo Introdução O objetivo deste estudo foi apresentar os resultados dos testes de avaliação sensitiva e do exame eletrofisiológico em pacientes com artrite reumatoide (AR) com deformidade do pé e determinar a sua relação com o estado geral de saúde e o aspecto funcional dos membros inferiores. Materiais e métodos Foram incluídos no estudo 51 pacientes com diagnóstico de AR e deformidade do pé. Foram registradas as características demográficas e da doença de cada indivíduo e foi feito um exame neurológico detalhado. Foi avaliada a sensibilidade superficial, dolorosa, térmica e vibratória e aplicado o teste de discriminação de dois pontos em cada um dos pés. A soma dos escores foi usada para determinar o índice de déficits sensitivos (IDS) de 0‐10. A presença de polineuropatia foi avaliada com métodos eletrofisiológicos. Foram usados o Health Assessment Questionnaire e as subescalas mobilidade e deambulação da Arthritis Impact Measurement Scales‐2 para avaliar o estado geral de saúde e o aspecto funcional de membros inferiores, respectivamente. De acordo com os resultados dos exames de eletromiografia e de sensibilidade, os pacientes foram comparados em relação ao seu estado geral de saúde e estado funcional de membros inferiores. Resultados Foram detectados distúrbios sensitivos em 39 pacientes (74%) durante o exame; contudo, 27 (52,9%) tinham polineuropatia determinada eletrofisiologicamente. Em pacientes com déficits sensitivos, foi detectada deterioração estatisticamente significativa no estado geral de saúde e no aspecto funcional do pé, inclusive na mobilidade e deambulação, quando comparados com os pacientes com uma avaliação sensitiva normal. Conclusão Mesmo na presença de testes eletrofisiológicos normais, a disfunção sensitiva isolada parece estar associada a incapacidade grave no estado geral de saúde e ao aspecto funcional do pé em comparação com pacientes com um exame sensitivo normal.

Importância do período de silêncio cutâneo na fibromialgia e sua relação com as características da doença, distúrbios psicológicos e qualidade de vida dos pacientes / Importance of cutaneous silent period in fibromyalgia and its relationship with disease characteristics, psychological disorders and quality of life of patients

INTRODUÇÃO: O período de silêncio cutâneo (PSC) é um reflexo protetor inibitório da coluna vertebral e seus aferentes consistem em fibras nervosas A-delta. Nosso objetivo foi avaliar pacientes com fibromialgia (FM) e controles saudáveis para determinar as diferenças entre os grupos em relação à duração e latência do PSC, e quando presente, determinar se há alguma relação com as características da doença, distúrbios psicológicos e qualidade de vida. MATERIAIS E MÉTODOS: Trinta e dois pacientes com FM e 32 voluntários saudáveis foram incluídos no estudo. Os dois grupos foram comparados em relação à latência e duração do PSC em ambos os membros superiores e inferiores. Características da doença, distúrbios psicológicos e qualidade de vida dos pacientes foram avaliados utilizando o Fibromyalgia Impact Questionnaire (FIQ), e o Short Form-36 (SF-36). Os pacientes com medida de PSC igual ou inferior às do grupo controle foram comparados com aqueles com valores mais elevados do que os controles em termos de características da doença, estado psicológicos e qualidade de vida. RESULTADOS: Latências significativamente prolongadas de PSC nos membros superiores e inferiores foram determinadas em pacientes comparados com os controles. Observou-se que a prolongamento da latência do PSC no membro inferior estava associado com a gravidade da doença e incapacidade funcional. CONCLUSÕES: Latências do PCS nos membros superiores e inferiores em pacientes com FM são mais longas do que em voluntários saudáveis. Além disso, o prolongamento da latência do PSC no membro inferior está associado com a gravidade da doença e incapacidade funcional física.

INTRODUCTION: Cutaneous silent period (CSP) is an inhibitory spinal protective reflex and its afferents consist of A-delta nerve fibers. We aimed to evaluate patients with fibromyalgia (FM) and healthy controls to determine any differences between the groups in terms of CSP duration and latency, and if present, to determine whether there is any relationship with disease characteristics, psychological disorders and quality of life. MATERIALS AND METHODS: Thirty-two patients with FM and 32 healthy volunteers were included in the study. The patient and control groups were compared in terms of CSP latency and duration in both upper and lower extremities. Disease characteristics, psychological disorders and quality of life of patients were assessed using the Fibromyalgia Impact Questionnaire (FIQ) and Short Form-36 (SF-36). Patients with CSP measurements equal to or lower than those of the control group were compared with those with higher values than controls in terms of disease characteristics, psychological status and quality of life. RESULTS: Significantly prolonged CSP latencies in both upper and lower extremities were determined in patients compared to controls. We found that prolongation of CSP latency in the lower extremity is associated with disease severity and functional disability. CONCLUSIONS: CSP latencies in both upper and lower extremities in patients with FM are longer than in healthy volunteers. Moreover, prolongation of CSP latency in the lower extremity is associated with disease severity and physical functional disability.

The relationship between bisphosphonate use and demographic characteristics of male osteoporosis patients

INTRODUCTION: This study aimed to investigate a number of demographic characteristics in males with osteoporosis (OP) treated with bisphosphonate and determine whether any of these measures could act as an effective indicator of medication persistence and compliance. MATERIAL AND METHOD: Among the patients with OP who applied to our clinic and were prescribed weekly oral bisphosphonate treatment, 89 patients over 50 years of age were included in this study. The demographic characteristics of these patients were evaluated. The number of medications used by the patients over the past 1 and 3 years were counted, and the persistence and compliance with bisphosphonate treatment was estimated. The patients were divided into two groups: fully compliant and noncompliant subjects. The two groups of patients were compared separately for 1 and 3 years while considering their demographic characteristics. RESULTS: The mean age of the 89 patients included in the study was 62.43 + 9.41 years. Comparisons among the studied demographic characteristics during the 1-year period of medication use indicated that the educational status of the fully compliant patients was higher. During the 3-year period of medication use, educational status was the only demographic characteristic that was determined to be significantly lower in the noncompliant patients than in the fully compliant group. CONCLUSION: Although deficiencies in medication persistence and compliance during osteoporosis treatment can lead to serious health and social problems in both genders, the causes of these deficiencies have not been thoroughly clarified. We suggest that the educational status of the patient may contribute to these deficiencies.
