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.

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.

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.

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.

Avaliação dos efeitos a longo prazo da acupuntura e exercícios terapêuticos em ombro congelado de pacientes com acidente cerebral vascular / Evaluation of long term effects of acupuncture and therapeutic exercises on frozen shoulder in stroke patients

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.

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.

Efeitos da reabilitação precoce no desfecho da reabilitação pós-acidente vascular encefálico (AVE) em mulheres com mais de 65 anos e sua correlação com a gravidade do deficit neurológico inicial / Efeitos da reabilitação precoce no desfecho da reabilitação pós-acidente vascular encefálico (AVE) em mulheres com mais de 65 anos e sua correlação com a gravidade do deficit neurológico inicial

Este trabalho visa examinar os efeitos da reabilitação precoce, a curto e longo prazo, no desfecho do acidente vascular encefálico (AVE) em mulheres com mais de 65 anos; estabelecer a correlação entre o impacto da gravidade do déficit neurológico na predição dos resultados do tratamento de Reabilitação e, ainda, investigar a possibilidade do acompanhamento de parâmetros individuais da Medição de Independência Funcional (MIF) na predição do desfecho da reabilitação do AVE. Atualmente, o AVE é a terceira maior causa de mortalidade na população mundial, bem como a maior causa de invalidez permanente. No cenário atual, as doenças cardiovasculares e cerebrovasculares - que antes eram tidas como exclusivas da população masculina ? têm afetado também as mulheres. Por outro lado, observamos uma correlação linear entre o envelhecimento e a ocorrência destas doenças. Concluímos que a implantação do método de reabilitação precoce conduz a uma aceleração significativa do processo de tratamento e recuperação após o AVE em mulheres com mais de 65 anos. Concluímos também que certos parâmetros da MIF, por apresentarem o mesmo padrão de evolução, podem ser utilizados na predição da recuperação global do paciente.

This study aims at verifying the effects of short- and long-term rehabilitation on the outcome of encephalic vascular accident (EVA) in women older than 65 years; establishing the correlation between the impact of the neurological deficit severity on the prediction of the rehabilitation treatment outcome as well as investigating the possibility of the follow-up of individual parameters at the Functional Independence Measure (FIM) when predicting the EVA rehabilitation outcome. The EVA is currently the third major cause of death in the world?s population, as well as the main cause of permanent disability. In the present scenario, cardiovascular and cerebrovascular diseases, which used to be observed almost exclusively in the male population, now affect the female population as well. On the other hand, we observe a linear correlation between aging and the occurrence of these diseases. We conclude that the implementation of early rehabilitation leads to a significant acceleration in the treatment and recovery process post-EVA in women older than 65 years. We also conclude that certain FIM parameters can be used to predict the patient?s overall recovery, as they present the same evolution pattern.
