RESUMO
BACKGROUND: Chronic spontaneous urticaria (CSU) is a condition that is associated with recurrent pruritic hives and/or angioedema lasting for more than 6 weeks and is known to affect 1% of the population. Neuropathic pain can be defined as abnormal pain in the peripheral or central nervous system following injury and results from dysfunctions in the peripheral or central nervous system without peripheral nociceptor stimulation. Histamine appears in the pathogenesis of both the CSU and diseases of the neuropathic pain spectrum. OBJECTIVE: To evaluate the symptoms of neuropathic pain in patients with CSU using scales. METHOD: Fifty-one patients with CSU and 47 sex- and age-matched healthy controls were included in the study. RESULTS: The results of the short-form McGill Pain Questionnaire revealed the scores in the sensory and affective domains, Visual Analogue Scale (VAS) scores and pain indices to be significantly higher in the patient group (pâ¯<â¯0.05 for all cases), while the overall pain assessment and sensory assessment based on the Self-Administered Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) pain scale were also significantly higher in the patient group. Based on the assumption that scores of > 12 indicated neuropathy, 27 (53%) of the patients in the patient group and 8 (17%) in the control group were found to have neuropathy (pâ¯<â¯0.05). STUDY LIMITATIONS: Cross-sectional study, small patient sample and use of self-reported scales. CONCLUSION: In addition to itching, patients with CSU should be aware of the potential for the association of neuropathic pain. In this chronic disease that is known to affect the quality of life, using an integrated approach with the patients and identifying accompanying problems are as important as treating the dermatological disorder.

OBJECTIVE: The effects of vitamin D on the central and peripheral nervous system continue to be investigated today. In the present study, we aimed to evaluate pain and electrophysiologic response in patients with carpal tunnel syndrome (CTS) who have undergone replacement therapy due to vitamin D deficiency. METHODS: Fifty female patients diagnosed with mild and moderate CTS and accompanied by vitamin D deficiency were included in this study. Nerve conduction study (NCS) was performed before and after vitamin D replacement, and the patient's pain was evaluated with Visual Analogue Scale (VAS). RESULTS: When NCS were compared before and after treatment, there was a statistically significant improvement in the median distal sensory onset latency (DSOL) and sensory conduction velocity (CV) and motor distal latencies (DML) values (p=0.001; p<0.001; p=0.001, respectively). At the same time, there was a decrease in the VAS values in patients (p<0.001). When the two groups were compared there was an improvement in DSOL and sensory CV in both groups, but in DML only in moderate CTS group. CONCLUSION: In this study, it was shown that mild and moderate CTS patients had an improvement in pain and electrophysiological parameters after vitamin D replacement. Replacing vitamin D in early stages of CTS may be beneficial.

Resumo Objetivo: Os efeitos da vitamina D no sistema nervoso central e periférico continuam sendo investigados atualmente. Neste estudo, objetivamos avaliar a dor e a resposta eletrofisiológica em pacientes com síndrome do túnel do carpo (STC) submetidos a terapia de reposição devido à deficiência de vitamina D. Métodos: Cinquenta pacientes do sexo feminino diagnosticadas com STC leve e moderada e acompanhadas de deficiência de vitamina D foram incluídas neste estudo. O estudo da condução nervosa (ECN) foi realizado antes e após a reposição da vitamina D, e a dor do paciente foi avaliada com a Escala Visual Analógica (EVA). Resultados: Quando a ECN foi comparada antes e após o tratamento, houve uma melhora estatisticamente significativa na latência mediana do início sensorial distal (DSOL) e nos valores de velocidade de condução sensorial (VC) e latência distal motora (LDM) (p=0,001; p<0,001; p=0,001, respectivamente). Ao mesmo tempo, houve uma diminuição dos valores da EVA nos pacientes (p<0,001). Quando os dois grupos foram comparados, houve uma melhora no DSOL e no VC sensorial em ambos, mas no LDM apenas no grupo STC moderado. Conclusão: Neste estudo, foi demonstrado que pacientes com STC leve e moderada apresentaram melhora da dor e parâmetros eletrofisiológicos após a reposição de vitamina D. A substituição da vitamina D nos estágios iniciais da STC pode ser benéfica.

INTRODUCTION: Although it is known that anxiety and depressive disorders frequently accompany migraine and TTH, the role of somatic amplification (SSA) and health anxiety in these diseases is not adequately known. OBJECTIVE: The aim of this study is to compare SSA and health anxiety in patients with migraine or TTH, and healthy controls and to investigate the relationships between SSA, health anxiety, headache characteristics, anxiety and depressive symptoms. METHODS: Fifty-four migraine, 50 TTH patients from the outpatient unit of the neurology department and 53 healthy volunteers were recruited for the study. The somatosensory amplification scale (SSAS), health anxiety inventory, Beck depression (BDI) and anxiety inventory (BAI) were administered to all participants. RESULTS: The SSAS scores were significantly higher in migraineurs compared with the healthy controls. The health anxiety scores were significantly higher in both migraine and TTH groups. The BDI and BAI scores were also significantly higher in migraine and TTH groups compared with the controls. A significant positive correlation was found between headache frequency and BAI scores, the visual analogue scale scores and SSAS and BDI scores in migraineurs. The SSAS scores were also significantly correlated with the BDI and BAI scores in both of the headache groups. A similar correlation was determined with the health anxiety scores. CONCLUSIONS: While patients with migraine and TTH evalute, taking into account the SSA and health anxiety may contribute to the prognosis and treatment of these diseases.

ABSTRACT Vitamin D is a pleiotropic steroid hormone that modulates the autonomic balance. Its deficiency has been described as an environmental risk factor for multiple sclerosis (MS). The aim of this study was to investigate the serum levels of vitamin D, vitamin D binding protein (VDBP) and vitamin D receptors (VDR) and to evaluate cardiac dysautonomia in MS patients due to bidirectional interaction between vitamin D and the autonomic nervous system. Methods: The current cross-sectional study was conducted on 26 patients with relapsing-remitting MS and on 24 healthy controls. Twenty-four-hour ambulatory blood pressure variability (BPV) was calculated and the participants were evaluated for orthostatic hypotension and supine hypertension. Serum levels of vitamin D, VDBP and VDR were measured. Results: The mean serum vitamin D level was significantly lower in MS patients than in controls (p = 0.044); however there was no significant difference in terms of VDR and VDBP levels between the groups. Supine hypertension and orthostatic hypotension were significant and the 24-hour systolic BPV was significantly decreased in patients with MS (p < 0.05) compared to controls. No correlation was found between vitamin D, VDBP and VDR with supine hypertension, orthostatic hypotension and systolic BPV values (p > 0.05). Also, there was a negative correlation between VDBP and the EDSS (p = 0.039, r = −0.406). Conclusion: There was no correlation between orthostatic hypotension, supine hypertension and systolic BPV values and serum vitamin D, VDBP and VDR in MS patients. Future prospective studies with large number of patients may help us to better understand the relationship between vitamin D and the autonomic nervous system.
RESUMO A vitamina D é um hormônio esteroide pleiotrópico que modula o equilíbrio autonômico. Sua deficiência tem sido descrita como fator de risco ambiental para esclerose múltipla (EM). O objetivo deste estudo foi investigar os níveis séricos de vitamina D, proteína de ligação à vitamina D (VDBP) e receptor de vitamina D (VDR) e avaliar a disautonomia cardíaca em pacientes com EM devida à interação bidirecional entre vitamina D e sistema nervoso autônomo. Métodos: O presente estudo transversal foi realizado em 26 pacientes com EM remitente-recorrente e em 24 controles saudáveis. A variabilidade da pressão arterial ambulatorial (BPV) por 24 horas foi calculada e os participantes foram avaliados quanto à hipotensão ortostática e hipertensão supina. Os níveis séricos de vitamina D, VDBP e VDR foram medidos. Resultados: O nível sérico médio de vitamina D foi significativamente menor nos pacientes com EM do que nos controles (p = 0,044); no entanto, não houve diferença significativa em termos de níveis de VDR e VDBP entre os grupos. Hipertensão supina e hipotensão ortostática foram significativas e a BPV sistólica de 24 horas diminuiu significativamente em pacientes com EM (p < 0,05) em comparação aos controles. Não foi encontrada correlação entre vitamina D, VDBP e VDR com hipertensão supina, hipotensão ortostática e BPV sistólica (p > 0,05). Também houve correlação negativa entre VDBP e EDSS (p = 0,039, r = −0,406). Conclusão: Não houve correlação entre hipotensão ortostática, hipertensão supina e valores de BPV sistólica e vitamina D sérica, VDBP e VDR em pacientes com EM. Futuros estudos prospectivos com grande número de pacientes podem nos ajudar a entender melhor a relação entre vitamina D e sistema nervoso autônomo.

RESUMO Embora se saiba que os distúrbios de ansiedade e depressão frequentemente acompanhem a enxaqueca e a TTH, o papel da amplificação somatossensorial (somatosensory amplification, SSA) e da hipocondria nessas doenças ainda não é bem conhecido. Objetivo: O presente estudo faz uma comparação entre pacientes que sofrem de enxaqueca e TTH com um grupo de controle saudável em termos de SSA e hipocondria e investiga a relação entre os achados e as características da cefaleia, a ansiedade e os sintomas depressivos. Métodos: O estudo incluiu 54 pacientes com enxaqueca, 50 pacientes com TTH e 53 voluntários saudáveis que se cadastraram na clínica de neurologia. A escala de amplificação somatossensorial (somatosensory amplification scale, SSAS), o inventário de hipocondria, o Inventário de Depressão de Beck (Beck Depression Inventory, BDI) e o Inventário de Ansiedade de Beck (Beck Anxiety Inventory, BAI) foram aplicados aos participantes. Resultados: Quando comparados com os controles saudáveis, as pontuações da SSAS dos pacientes com enxaqueca foram significativamente maiores, enquanto as pontuações de hipocondria foram significativamente maiores em ambos os grupos de enxaqueca e TTH. As pontuações do BAI e do BDI foram significativamente maiores em ambos os grupos de pacientes que no grupo de controle. No grupo da enxaqueca, foi identificada uma correlação positiva entre frequência de cefaleia e ansiedade, bem como entre a Escala Analógica Visual (EVA), a SSAS e a depressão. Em ambos os grupos de pacientes, a SSA foi correlacionada positivamente com a depressão e a ansiedade, e uma correlação semelhante foi encontrada entre a SSA e a hipocondria. Conclusão: Em avaliações dessas doenças, a hipocondria e a SSA devem ser levadas em consideração, pois se acredita que essa abordagem possa contribuir positivamente para o prognóstico e tratamento da doença.
