Onset of leukocytoclastic vasculitis following covid-19 vaccination: case based comprehensive review.

With the global introduction and widespread administration of COVID-19 vaccines, there have been emerging reports of associated vasculitis, including leukocytoclastic cutaneous vasculitis (LCV). In this paper, we present a case of a 68-year-old female patient who developed painful purpuric skin lesions on her feet 12 days after administration of the inactivated COVID-19 vaccine BBIBP Cor-V with histopathological confirmation of LCV and no signs of systemic involvement. The case is followed by a comprehensive literature review of documented LCV cases associated with COVID-19 vaccination with overall 39 articles and 48 cases of LCV found in total. In the majority of cases (56.3%) the first symptom occurred after the first dose of the COVID-19 vaccine, with symptoms manifesting within an average of seven days (6.8 ± 4.8) post-vaccination. The adenoviral vaccine Oxford-AstraZeneca (41.7%) and the mRNA vaccine Pfizer-BioNTech (27.1%) were most frequently associated with LCV occurrences. On average, LCV resolved within 2.5 (± 1.5) weeks. The preferred treatment modality were glucocorticoids, used in 70.8% of cases, resulting in a positive outcome in most cases, including our patient. While the safety of a subsequent dose appears favorable based on our review, individual risk-benefit assessment is crucial. This review emphasis the importance of considering COVID-19 vaccination as a potential trigger for the development of cutaneous vasculitis. Despite rare adverse events, the benefits of the COVID-19 vaccination outweigh the risks, highlighting the importance of immunization programs.

Epstein-Barr Virus Reactivation as a New Predictor of Achieving Remission or Lupus Low Disease Activity State in Patients with Systemic Lupus Erythematosus with Cutaneous Involvement.

Although Epstein-Barr virus (EBV) reactivation has long been associated with the pathogenesis of systemic lupus erythematosus (SLE), many aspects of this relationship remain unclear. Our objective was to investigate the association between EBV reactivation and the achievement of SLE remission and lupus low disease activity state (LLDAS) over a six-month period. Clinical, laboratory, and virological tests (anti-EBV antibodies and EBV DNA) were performed among 51 patients with the active form of SLE on two occasions six months apart. SLE remission and LLDAS achievement were assessed at the end of the follow-up period. Active EBV infection was detected in 45% of active SLE patients at baseline, and 77% transitioned to latent EBV infection at six months (p < 0.001). Multivariate regression revealed a higher titer of anti-EA(D) IgM-Abs and the presence of anti-EA(D) IgM-Abs as independent predictors of remission and LLDAS in SLE patients with mucocutaneous manifestations (p = 0.042) and rash only (p = 0.023), respectively. Since a higher C3 level was an independent predictor of transition to latent EBV infection (p = 0.027), the estimated cut-off value that could identify active SLE patients who will transition to latent EBV infection after six months was ≥0.780 g/L with a sensitivity of 70.6% and a specificity of 75.0% (AUC = 0.756, p = 0.003). EBV reactivation is common in patients with active SLE, and most of them transition to latent EBV infection after six months. Achieving remission and LLDAS in SLE patients with mucocutaneous manifestations can be predicted by a higher titer, whereas in SLE patients who have only a rash, the presence of anti-EA (D) IgM-Abs was a predictor of remission and LLDAS.

Biomarkers of disease activity in patients with chronic spontaneous urticaria.

INTRODUCTION: Previous studies have examined biomarkers of coagulation, inflammation and immunity in chronic spontaneous urticaria (CSU), but no recommended biomarkers for disease activity have been established yet. AIM: To find the relationship between certain laboratory parameters and disease activity in patients with CSU. MATERIAL AND METHODS: Serum concentrations of D-dimer, C-reactive protein (CRP), C3, C4, and prothrombin time (PT), activated partial thromboplastin time (aPTT) values were measured in 44 CSU patients and compared with 33 healthy controls. Correlation between biomarkers and urticaria activity score during 7 consecutive days (UAS7) was calculated. RESULTS: Our study included 44 CSU patients (38 females and 6 males), mean age of 50.4 years and the average disease duration of 3.1 years. Based on UAS7, 23 (52.3%) CSU patients had mild urticaria, 8 (18.2%) well-controlled, 7 (15.9%) moderate and 6 (13.6%) severe urticaria. Fourteen (31.8%) patients had elevated CRP, 21 (47.7%) had elevated D-dimer and 14 (13.6%) CSU patients had elevated C4 levels. Patients with CSU had statistically significant elevated D-dimer, CRP and PT as compared with controls (p = 0.007, p = 0.005 and p = 0.029, respectively). There was no correlation between PT, aPTT, D-dimer, CRP, C3 and disease activity. Statistically significant differences in C4 levels between patients with severe and well-controlled, mild, moderate urticaria were determined (p = 0.003). CONCLUSIONS: CRP, D-dimer, and PT may be considered as biomarkers for distinguishing patients with CSU from controls. The C4 levels correlate with disease activity and may be useful as a potential biomarker of disease activity.

Severe strongyloidiasis and systemic vasculitis: comorbidity, association or both? Case-based review.

A possible association between strongyloidiasis and systemic vasculitis is rarely reported in the literature. We report the case of a patient with severe strongyloidiasis and an angiographic finding consistent with polyarteritis nodosa. Diagnosis of strongyloidiasis was made by finding of larvae and adult parasites in samples of the upper gastrointestinal tract mucosa and stool. The patient was treated with albendazole, ivermectin and corticosteroid withdrawal. This therapy led to the resolution of symptoms, with repeated stool samples negative for S. stercoralis. However, the clinical course was complicated with pulmonary tuberculosis. Despite tuberculostatic therapy and supportive measures, a lethal outcome occurred. The report is followed by a focused review of the available literature on the association of strongyloidiasis and systemic vasculitis.

Asthma Inflammatory Phenotypes: How Can We Distinguish Them?

BACKGROUND AND OBJECTIVES: induced sputum is used to assess different inflammatory phenotypes in asthma, but is not used routinely. We aimed to determine the proportion of inflammatory asthma phenotypes based on induced sputum, to find biomarkers that can discriminate between phenotypes, and to evaluate biomarkers in patients with and without biological therapy in different inflammatory asthma phenotypes. MATERIALS AND METHODS: this cross-sectional study investigated clinical characteristics, asthma control tests, skin prick test, impulse oscillometry (IOS), spirometry, induced sputum, biomarkers (IgE, eosinophils, fractional exhaled nitric oxide (FeNO), serum periostin, IL-5, IL-6, IL-8, IL-17A, IL-33) in 80 asthmatics. A total of 17/80 patients were treated with biologics (10 with omalizumab, 7 with benralizumab). RESULTS: a total of 31% of patients had eosinophilic asthma (EA), 30% had mixed granulocytic asthma (MGA), 24% had paucigranulocytic asthma (PGA), and 15% had neutrophilic asthma (NA). The difference was found in blood eosinophils (p = 0.002), the highest observed in EA. The cut-off ≥ 240/µL eosinophils, with 64% sensitivity and 72.7% specificity, identified EA (AUC = 0.743, p = 0.001). A higher IL-8 level was associated with NA (p = 0.025). In 63 non-biologic asthma group, eosinophils were higher in EA than in NA, MGA, and PGA (p = 0.012, p = 0.028, and p = 0.049, respectively). A higher IL-17A was associated with EA without biologics (p = 0.004). A significantly higher IL-5 was found in EA treated with biologics, in comparison with EA without biologics (p = 0.043). The number of leucocytes and neutrophils was higher in MGA without biologics (p = 0.049, p = 0.019), while IL-5, IL-6, and IL-8 levels were higher in MGA treated with biologics (p = 0.012, p = 0.032, p = 0.038, respectively). CONCLUSIONS: EA and MGA were the most prevalent asthma phenotypes. Blood eosinophils can identify EA, both in patients with and without biologics. Apart from the clinical profile, a broad spectrum of biomarkers for assessing inflammatory phenotypes is necessary for an adequate therapy approach to patients with asthma.

Successful Desensitization to Sorafenib and Imatinib-A Report of Two Cases and a Literature Review.

BACKGROUND: Drug desensitization allows for safe administration of a drug to a patient with a previous hypersensitivity reaction. Successful desensitization protocols have been described for different medications, including protocols for oncology patients. Few cases of desensitization to sorafenib and imatinib have been described in the literature so far. OBJECTIVE: The objective of this paper is to describe the process of the sorafenib and imatinib drug hypersensitivity diagnosis and desensitization process in two patients. METHODS: Two oncology patients who experienced non-immediate hypersensitivity reactions to sorafenib and imatinib underwent desensitization to these drugs. We designed a protocol for the first patient and used a modified protocol from the literature for the second patient. RESULTS: By using a slow desensitization technique and gradual tapering of corticosteroids and antihistamines, both patients reached the target dose of the incriminated drug. CONCLUSIONS: Desensitization to sorafenib and imatinib can be an effective therapeutic option in patients with hypersensitivity to those medications, without alternative treatment options.

Autoimmune/inflammatory syndrome induced by adjuvants in a woman with Hashimoto thyroiditis and familial autoimmunity-a case report and literature review.

Introduction: Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) consists of a wide spectrum of symptoms and immunological features that are believed to develop in predisposed individuals after exposure to an adjuvant, including a silicone breast implant (SBI). Different autoimmune diseases (AIDs) have been associated with ASIA, but ASIA development after SBI in women with Hashimoto thyroiditis (HT) and familial autoimmunity has rarely been described. Case report: A 37-year-old woman presented in 2019 with arthralgia, sicca symptoms, fatigue, + antinuclear antibody (ANA), + anti SSA, and + anticardiolipin Immunoglobulin G (IgG) antibodies. She was diagnosed with HT and vitamin D deficiency in 2012. The familial autoimmunity was present: the patient's mother had been diagnosed with systemic lupus erythematosus and secondary Sjogren's syndrome and her grandmother with cutaneous lupus and pernicious anemia. In 2017, the patient had a cosmetic SBI procedure that was complicated by repeated right breast capsulitis. After 2 years of irregular visits due to COVID-19, she presented with + ANA, + anticentromere antibodies both in sera and seroma, sicca syndrome, arthralgias, twinkling in extremities, abnormal capillaroscopic findings, and reduced diffusing capacity of the lungs for carbon monoxide. She was diagnosed with ASIA, and antimalarial and corticosteroid therapy were introduced. Conclusion: In patients with HT and familial autoimmunity, SBI should be carefully considered due to the possibility of ASIA development. Hashimoto thyroiditis, familial autoimmunity, and ASIA seem to be interconnected in the complex mosaic of autoimmunity in predisposed individuals.

CT and 18FDG-PET/CT findings in progressive mediastinal idiopathic fibrosis as a benign mimicker of esophageal carcinoma: a case report.

Idiopathic mediastinal fibrosis, also called sclerosing or fibrosing mediastinitis, is a very rare and aggressive fibroinflammatory process characterized by fibrous tissue proliferation in the mediastinal region. Herein, we present a rare case of idiopathic mediastinal fibrosis presenting with esophageal obstruction, most likely associated with immunoglobulin G (IgG4)-related disease, affecting the posterior mediastinum with intrapulmonary infiltration. Computed tomography revealed a narrowed lumen and thickened wall of the distal esophagus surrounded by a necrotic mass with infiltration into the nearby structures, suggesting a locally advanced malignant process. Positron emission tomography revealed intense accumulation of 18F-fluorodeoxyglucose, indicating an active inflammatory component, which complicates further differential diagnosis of mediastinal masses. Thoracoscopic biopsy and immunohistochemical analysis confirmed a fibroinflammatory process with perivascular lymphoid cell infiltration that was cluster of differentiation (CD)3 (++) and CD20 (++), with massive numbers of IgG4-immunoreactive plasma cells. Although a benign condition, sclerosing mediastinitis is a close mimicker of esophageal carcinoma, which cannot be differentiated by computed tomography or positron emission tomography and must be considered in a differential diagnosis.

Successful Immunomodulatory Treatment of COVID-19 in a Patient With Severe ACTH-Dependent Cushing's Syndrome: A Case Report and Review of Literature.

Introduction: Patients with Cushing's syndrome (CS) represent a highly sensitive group during corona virus disease 2019 (COVID-19) pandemic. The effect of multiple comorbidities and immune system supression make the clinical picture complicated and treatment challenging. Case report: A 70-year-old female was admitted to a covid hospital with a severe form of COVID-19 pneumonia that required oxygen supplementation. Prior to her admission to the hospital she was diagnosed with adrenocorticotropic hormone (ACTH)-dependent CS, and the treatment of hypercortisolism had not been started yet. Since the patient's condition was quickly deteriorating, and with presumend immmune system supression due to CS, we decided on treatement with intraveonus immunoglobulins (IVIg) that enabled quick onset of immunomodulatory effect. All comorbidities were treated with standard of care. The patient's condition quickly stabilized with no direct side effects of a given treatment. Conclusion: Treatment of COVID-19 in patients with CS faces many challenges due to the complexity of comorbidity effects, immunosupression and potential interactions of available medications both for treatment of COVID-19 and CS. So far, there are no guidelines for treatment of COVID-19 in patients with active CS. It is our opinion that immunomodulating therapies like IVIg might be an effective and safe treatment modality in this particularly fragile group of patients.

Vitamin D Status in Patients with Systemic Lupus Erythematosus in Serbia: Correlation with Disease Activity and Clinical Manifestations.

BACKGROUND: Numerous studies indicate potential role of vitamin D as an important factor in the development of many autoimmune diseases including systemic lupus erythematosus (SLE). Patients with SLE are especially prone to the development of vitamin D deficiency due to the nature of their illness. AIM: The aims of our study were to determine the prevalence of vitamin D insufficiency and deficiency in patients with SLE in Serbia, to identify clinical variables associated with vitamin D status and to examine the impact of vitamin D status on disease activity and presence of specific lupus autoantibodies. MATERIAL AND METHODS: The study included 46 patients with SLE. Serum 25(OH)D concentration was measured by electrohemiluminiscent immunoassay. RESULTS: The mean serum concentration of 25(OH)D was 11.9 ± 7.3 ng/ml. The prevalence of insufficiency was 32.6%, while the prevalence of deficiency was 67.4%. There was no association between vitamin D status and photosensitivity, skin lesions, arthritis and lupus nephritis. Vitamin D status was not associated with the presence of specific autoantibodies. There was no correlation between disease activity assessed by SLEDAI scale with the concentration of 25(OH)D. Patients who used vitamin D supplements and calcium did not have a significantly higher concentration of 25(OH)D. CONCLUSION: In conclusion, vitamin D deficiency is common in patients with SLE.

Systemic Lupus Erythematosus and Secondary Antiphospholipid Syndrome after Thymectomy for Myasthenia Gravis - A Case Report.

INTRODUCTION: Systemic lupus erythematosus (SLE) and myasthenia gravis (MG) are autoimmune diseases that show some similarities: a higher incidence in young women, relapsing-remitting course and positive anti-nuclear antibodies (ANA). However, they are two different clinical syndromes, which can coexist or precede each other. Thymectomy is a therapeutic option for patients with severe MG or thymoma. There are many cases of SLE after thymectomy described in the literature, so the question arises whether thymectomy predisposes patients to SLE and what are imunopathogenetic mechanisms behind this process. CASE REPORT: We report a case of a patient who was diagnosed with SLE and secondary antiphospholipid syndrome (APS) 28 years after thymectomy for MG. Clinical picture of SLE was characterized by cutaneous and articular manifestations, polyserositis, lupus nephritis and immunological parameters showed positive ANA, anti-ds-DNA, excessive consumption of complement components, positive cryoglobulins. Clinical and laboratory immunological parameters for the diagnosis of secondary APS where also present. The patient was initially treated with glucocorticoids followed by mycophenolate mofetil. During one year follow-up patient was in a stable remission of SLE. CONCLUSION: Thymectomy for MG may predispose SLE development in some patients. Further studies are needed to better understand the connection between these two autoimmune diseases.

Sjögren's Syndrome and Silicosis - a Case Report.

Sjögren's syndrome is an autoimmune disease of unknown etiology where immune response to self-antigens is believed to result from interactions between genetic and environmental factors. We describe the case of a patient who has been diagnosed with Sjögren's syndrome based on typical clinical and immunological parameters. The clinical picture was dominated by the respiratory symptoms, and radiographic and multislice computed tomography examination of the chest showed certain changes characteristic of pneumoconiosis. Given that the patient has worked in a foundry where he has been exposed to the silica dust, he was subject to examination by occupational health specialists under the suspicion of lung silicosis, who confirmed the silicosis. This case report points to the possible connection between a professional exposure to silica and Sjögren's syndrome. Occupational exposure to silica is a possible risk factor for the development of autoimmune diseases, and in the evaluation of patients with connective tissue diseases it is important to consider work-related history.

[Effects of functional electrical therapy on upper extremity functional motor recovery in patients after stroke--our experience and future directions].

INTRODUCTION: New neurorehabilitation together with conventional techniques provide methods and technologies for maximizing what is preserved from the sensory motor system after cerebrovascular insult. The rehabilitation technique named functional electrical therapy was investigated in more than 60 patients in acute, subacute and chronic phase after cerebrovascular insult. The functional sensory information generated by functional electrical therapy was hypothesized to result in the intensive functional brain training of the activities performed. FUNCTIONAL ELECTRICAL THERAPY: Functional electrical therapy is a combination of functional exercise and electrical therapy. The functional electrical therapy protocol comprises voluntary movement of the paretic arm in synchrony with the electrically assisted hand functions in order to perform typical daily activities. The daily treatment of 30 minutes lasts three weeks. The outcome measures include several tests for the evaluation of arm/hand functionality: upper extremity function test, drawing test, modified Aschworth scale, motor activity log and passive range of movement. RESULTS OF FUNCTIONAL ELECTRICAL THERAPY STUDIES: Results from our several clinical studies showed that functional electrical therapy, if applied in acute and subacute stroke patients, leads to faster and greater improvement of functioning of the hemiplegic arm/hand compared to the control group. The outcomes were significantly superior at all times after the treatment for the higher functioning group. DISCUSSION: Additional well-planned clinical studies are needed to determine the adequate dose of treatment (timing, duration, intensity) with functional electrical therapy regarding the patient's status. A combination with other techniques should be further investigated.

Pulse low-intensity electromagnetic field as prophylaxis of heterotopic ossification in patients with traumatic spinal cord injury.

BACKGROUND/AIM: Heterotopic ossification (HO) is an important complication of head and spinal cord injuries (SCI). Pulse low-intensity electromagnetic field (PLIMF) therapy increases blood flow to an area of pain or inflammation, bringing more oxygen to that area and helps to remove toxic substances. The aim of this study was to determine the effect of PLIMF as prophylaxis of HO in patients with SCI. METHODS: This prospective random control clinical study included 29 patients with traumatic SCI. The patients were randomly divided into experimental (n=14) and control group (n=15). The patients in the experimental group, besides exercise and range of motion therapy, were treated by PLIMF of the following characteristics: induction of 10 mT, frequency of 25 Hz and duration of 30 min. Pulse low-intensity electromagnetic field therapy started in the 7th week after the injury and lasted 4 weeks. The presence or absence of HO around the patients hips we checked by a plane radiography and Brookers classification. Functional capabilities and motor impairment were checked by Functional Independent Measure (FIM), Barthel index and American Spinal Injury Association (ASIA) impairment class. Statistic analysis included Kolmogorov-Smimrnov test, Shapiro-Wilk test, Mann Whitney Exact test, Exact Wilcoxon signed rank test and Fischer Exact test. Statistical significance was set up to p<0.05. RESULTS: At the end of the treatment no patient from the experimental group had HO. In the control group, five patients (33.3%) had HO. At the end of the treatment the majority of the patients from the experimental group (57.14%) moved from ASIA-A to ASIA-B class. CONCLUSION: Pulse low-intensity electromagnetic field therapy could help as prophylaxis of HO in patients with traumatic SCI.

Pain, functional status, social function and conditions of habitation in elderly unilateraly lower limb amputees.

BACKGROUND/AIM: Few authors are involved in home rehabilitation of amputees or their reintegration into the community. It has been remarked that there is a discontinuity between the phases of the amputee rehabilitation in Serbia. The aim of the study was to establish pain characteristics and functional status of amputees two months after the amputation and to determine their social function and the conditions of their habitation. METHODS: This prospective observation study involved 38 elderly amputees with unilateral lower limb amputations. The patients were tested at the hospital on discharge and at their homes two months after the amputation. Pain intensity and functional status were measured by a visual analogue scale (VAS) and by Functional Independence Measure (FIM). The patients' social function was assessed using the Social Dysfunction Rating Scale (SDRS) and conditions of their habitation by the self-created Scale of Conditions of Habitation (SCH). In statistic analysis we used the Student t test, chi2 test and Analysis of variance (ANOVA). RESULTS: The majority of patients (63%) underwent below knee amputation caused by diabetes (89%). A significant number of patients (84%, chi2 = 17.78; p < 0.01) was not visited by a physiotherapist nor an occupational therapist during two months at home. In this period, the majority of the amputees (68%) had phantom pain or residual limb pain (21%). Two months after amputation the pain intensity was significantly lower (VAS = 4.07 +/- 2.19; 2.34 +/- 1.41; p < 0.001), and the functional status significantly better than on discharge (FIM = 75.13 +/- 16.52; 87.87 +/- 16.48; p < 0.001). The amputees had the average level of social dysfunction (SDRS = 62.00 +/- 11.68) and conditions of habitation (SCH = 7.81 +/- 1.97). CONCLUSION: A total 38 elderly amputees with unilateral lower limb amputations achieved significant functional improvement and reduction of pain, in spite of their social dysfunction, the absence of socio-medical support and inadequacy of the conditions of habitation.

Objetivo do estudo: Determinar como a acupuntura e a terapia com exercícios afetam a função motora e espasmodicidade das mãos de pacientes com acidente cerebral vascular 6 meses após eles terem recebido este tipo de terapia. Métodos: Estudo clínico prospectivo, aleatório e cego de 20 pacientes, com idades entre 60-70 anos, na fase crônica de 6 meses após o AVC. Os sujeitos do estudo foram divididos em dois grupos: Grupo A, o qual foi tratado com acupuntura e terapia de exercícios (AP-ET) 6 meses atrás e Grupo B, o qual foi tratado apenas com terapia de exercícios (ET) 6 meses atrás. A avaliação incluiu uma entrevista ampla e a administração dos estágios de Brunnstrom, a Medida de Independência Funcional (MIF), a Escala Modificada de Ashworth (MAS), o Teste de Funcionalidade das Extremidades Superiores (UEFT), o Registro de Atividade Motora (MAL), a Série de Movimentos ativos e passivos (ROM, pROM), o teste de FUGL-Meyer da função da extremidade superior (FMA), o Questionário de Croft sobre Incapacidade do Ombro (CSDQ) e a Escala Analógica Visual (VAS) de dor. O Teste-t de Gosset foi usado para uma análise estatística. Resultados: As análises mostraram uma diferença estatisticamente significativa nos SCORES do pós-tratamento em comparação com 6 meses após o tratamento com cada grupo de estudo, para todos os parâmetros examinados (p<0.01 em todos os casos) exceto pelo MAS.

Aim of the study: To determine how acupuncture and exercise therapy affect motor function and spasticity on the hands of stroke patients 6 months after they had received this kind of therapy. Methods: Prospective, randomized, single blind clinical study of 20 patients, age 60-70 years, in the chronic phase 6 months after stroke. Subjects were divided into two groups: Group A, which was treated with acupuncture and exercise therapy (AP-ET) 6 months ago and Group B, which was treated with exercise therapy (ET) alone 6 months ago. the assessment included a comprehensive interview and administration of the Brunnstrom?s stages, Functional Independence Measure (FIM), Modified Ashworth Scale (MAS), Upper Extremity Function Test (UEFT), Motor Activity Log (MAL), active and passive Range of Motion (aROM, pROM), Fugl-Meyer test of upper extremity function (FMA), Croft Shoulder Disability Questionnaire (CSDQ) and Visual Analogue Scale (VAS) of pain. The Gosset t-Test was used for the statistical analysis. Results: Analyses showed a statistically significant difference in the post-treatment SCORES as compared to 6 months after treatment within each study group for all parameters examined (p<0.01 in all cases) except for MAS. Analyses showed a statistically significant difference in some parameters in the ET group as compared to the AP-ET group with greater mean values recorded in the AP-ET group for MAS and CSDQ. All other parameters showed no statistical differences between the two different therapy groups 6 months after the therapy. Conclusion: The results confirm the hypothesis that acupuncture and exercise therapy are useful in the treatment of frozen shoulder in stroke patients and that their effects are still present after 6 months of therapy, however, given the small patient population, further studies are needed to verify these results.

Houve uma melhora na qualidade geral da utilização do braço, conforme mensurado pela escala qualitativa MAL. Conclusões: A terapia com Estimulação Elétrica Funcional (FET) em pacientes com acidente cerebrovascular subagudo com alta motivação para tarefas específicas pode ser um método eficaz para a melhora do funcionamento e da utilização dos braços afetados.

Effect of transcutaneous electrical nerve stimulation for the management of postoperative surgical pain after lower extremity amputation: a pilot study / Efeito da estimulação elétrica nervosa transcutânea (TENS) no tratamento de dor pós-cirúrgica após amputação de membro inferior: estudo piloto

A estimulação elétrica nervosa transcutânea (TENS) é uma modalidade não-médica e não-invasiva. Há muita controvérsia e atitudes contrárias em relação ao lugar que a TENS ocupa no tratamento da dor após amputação de membro inferior. Objetivo: Avaliar o papel da TENS no tratamento de dor cirúrgica pós-operatória após amputação de membro inferior. Material e métodos: Teste controlado randomizado, conduzido com 46 indivíduos submetidos à amputação de membro inferior, que foram aleatoriamente divididos em grupo controle e grupo tratado. O grupo controle recebeu cuidados-padrão no pós-operatório; o grupo tratado recebeu cuidados-padrão e aplicação de TENS. Quarenta indivíduos completaram efetivamente o estudo de acordo com o protocolo de estudo. A maior parte das amputações consistiu de amputação transtibial devido a complicações da diabete. Foram utilizados cinco dispositivos portáteis Ultima TENS XL-A1 com eletrodos auto-adesivos. Esta é a aplicação convencional da TENS, caracterizada pela aplicação de impulsos elétricos com a duração de 200 microssegundos, freqüência de 110 Hz e amplitude de 44 V. O tratamento foi administrado durante 10 dias, 2 horas por dia. A avaliação da eficácia da TENS foi feita utilizando-se a escala visual analógica (EVA) horizontal (0-100 mm). O teste t de Student foi usado na análise estatística. Resultados: A intensidade da dor estava significantemente diminuída em ambos os grupos no 10º dia em comparação ao 1º dia de pós-operatório. Não houve diferenças significantes entre o grupo controle (EVA = 4,18±1,48) e o grupo tratado (EVA= 3,59±1,44), de acordo com a intensidade média diária da dor (t = 1,25; df=38). A intensidade da dor no 10º dia de pós-operatório foi significantemente menor no grupo tratado (EVA = 1,65± 0,80 ) versus o grupo controle (EVA = 3,2± 1,15; t = 5; df = 38; p< 0,01 ). Conclusão: A TENS convencional (dose: 200 microssegundos, 110 Hz, 44 V), administrada 2 horas por dia, durante 10 dias, significantemente reduziu a dor cirúrgica pós-operatória em 20 indivíduos com amputação de membro inferior.

Transcutaneous electrical nerve stimulation (TENS) is a noninvasive, nonmedical modality. There are a lot of dilemmas and opposing attitudes regarding the use of TENS in pain management after lower limb amputations. Objective: To establish the role of TENS for the management of postoperative surgical pain after lower limb amputations. Material and methods: Randomized controlled trial, which included forty-six subjects who had undergone lower limb amputations, randomly divided into control and treatment group. The control group received standard postoperative care, whereas the treatment group received standard postoperative care plus TENS. Forty subjects successfully completed the study according to the study protocol. The majority of the individuals had undergone transtibial amputation due to complication of diabetes. Five Ultima TENS XL-A1 portable devices with four self-adhesive electrodes were used. This was the conventional TENS mode, characterized by the delivery of electrical impulses with a duration of 200 microseconds, frequency of 110 Hz, and amplitude of 44V. Treatment was carried out for 2 hours a day, during 10 days. The evaluation of TENS efficacy was performed using the horizontal VAS (0-100 mm). Student T test was used in the statistical analysis. Results: Pain intensity was significantly diminished in both groups at the tenth in comparison with the first postoperative day. There was no significant difference between the control (VAS = 4.18±1.48) and the treatment group (VAS= 3.59±1.44) according to the daily mean pain intensity (t = 1.25; df =38). Pain intensity on the tenth postoperative day was significantly lower in the treatment (VAS = 1.65± 0.80) when compared with the control group (VAS = 3.2± 1.15; t = 5; df = 38; p< 0.01). Conclusion: Conventional TENS (dose: 200 microseconds, 110 Hz, 44V), administered two hours a day during ten days, significantly reduced postoperative surgical pain in twenty subjects who had undergone lower limb amputations.
