Background : Development of methods to accelerate nerve regeneration in peripheral nerve damage is important. Electroacupuncture is a new therapeutic method that combines traditional acupuncture with modern electrotherapy. Melatonin has been shown to reduce nerve damage. Objectives: In this study, we aimed to determine and compare the therapeutic effects of electroacupuncture and melatonin on rat sciatic nerve injury. Methods : A total of 56 adult male Wistar Albino rats were divided into four study groups with 14 animals in each group: intact control (group I), subcutaneous saline (group II), subcutaneous melatonin (group III), and electroacupuncture (group IV). Surgical procedure including unilateral (right) sciatic nerve injury was applied to groups II, III, and IV. Saline and melatonin started immediately after surgery for six weeks, while electroacupuncture was given two weeks after surgery for 3 weeks. Functional and histological assessments were used as outcome measurements. Results : Sciatic nerve damage caused a significant decrease in nerve conduction velocity. Both electroacupuncture treatment and melatonin treatment significantly increased the nerve conduction velocity. Both sciatic functional recovery and histological regeneration were faster in these treatment groups compared to the saline. However, no significant difference was observed between the two treatment groups. Conclusion : Electroacupuncture and melatonin are promising alternative treatment strategies for peripheral nerve damage and can be examined in detail in future studies.

RESUMOIntroduçãoA espondilite anquilosante (EA) é uma doença reumática inflamatória crônica caracterizada pela inflamação da pelve e da coluna vertebral, que resulta em uma restrição na mobilidade da coluna vertebral. Em decorrência da postura alterada e da dor inflamatória noturna, os distúrbios do sono são passíveis de ocorrer em pacientes com EA.ObjetivoDeterminar as diferenças entre os pacientes com EA e controles saudáveis na qualidade do sono, bem como avaliar a relação entre a qualidade do sono e a atividade da doença.MétodoPara avaliar a qualidade do sono, 55 pacientes com EA (40 homens, 15 mulheres, idade média 43 ± 1 anos) que preencheram os critérios modificados de Nova York e 55 controles comparáveis (40 homens, 15 mulheres, idade média 42 ± 9 anos) preencheram o questionário Índice de Qualidade do Sono de Pittsburgh (PSQI). A atividade da doença foi avaliada pelo Bath Ankylosing Spondylitis Disease Activity Index (BASDAI).ResultadosA espondilite anquilosante se correlacionou significativamente com a qualidade de sono prejudicada de acordo com os escores totais do PSQI (p = 0,001). Foram encontradas diferenças significativas entre os pacientes com EA e controles saudáveis nos domínios do PSQI, incluindo "qualidade subjetiva do sono" (p = 0,010), "duração do sono" (p = 0,011), "eficiência do sono habitual" (p = 0,034), "distúrbios do sono" (p = 0,003) e "disfunção diurna" (p = 0,009), mas não na "latência do sono" e no "uso de medicação para dormir". Houve uma correlação positiva entre as pontuações do BASDAI e do PSQI (r = 0,612, p = 0,001).ConclusãoVerificou-se que os distúrbios do sono foram significativamente maiores em pacientes com EA em comparação com os controles. Os pacientes com doença ativa apresentaram pior qualidade de sono. Além disso, a atividade da doença esteve correlacionada com a pontuação da maior parte das subescalas do PSQI. A investigação da qualidade do sono deve ser uma ferramenta usada na avaliação de pacientes com EA.

Objective: Torsades de pointes (TdP) during bradyarrhythmias have been reported to be associated with gender, degree of QT prolongation and duration of bradyarrhythmia. We sought to investigate the repolarization characteristics on 12-lead electrocardiogram (ECG) and the incidence of TdP in patients with acquired complete atrioventricular block (CAVB). Methods: Fifty consecutive patients with acquired CAVB were included in the study. Patients with coronary artery disease, systolic dysfunction and previous cardiac surgery were excluded. Patients were monitored during hospitalization for ventricular arrhythmias (VA). Serum potassium, magnesium, calcium levels and thyroid-stimulating hormone were measured. Heart rate, QRS duration, QT/QTc, JT/JTc and Tpeak-Tend intervals were measured. Pathologic U waves, T-U complex, and QT morphologies were remarked. Results: Patients presented with presyncope (n=39, 78%), syncope (n=12, 24%), and palpitations (n=8, 16%). All patients were in sinus rhythm. Duration of CAVB was 8.5 days (median). Patients were divided into two groups based on JT interval. Group 1 (JT=or>500 ms, n=13) tended to have more female patients and more VAs in comparison to Group 2 (JT<500 ms, n=37). Group 1 patients had more pathologic U waves and T-U complexes, longer Tpeak-Tend intervals, and more long QT2 syndrome (LQT2)-like QT morphology in comparison to Group 2 patients. Group 2 patients had more often syncope. One patient in Group 2 developed ventricular fibrillation in the presence of hypokalemia and hypomagnesemia. Conclusion: Torsades de Pointes during CAVB was rare among our patient population. The predictors of VA during CAVB were presence of prolonged QTc/JTc intervals, pathologic U wave and T-U complex, prolonged Tpeak-Tend interval, and LQT2-like QT morphology. [ABSTRACT FROM AUTHOR]
