Termoterapia associada com treinamento de flexibilidade não aprimora a amplitude de movimento de joelhos em adultos saudáveis: revisão sistemática de ensaios clínicos randomizados com meta-análise / Thermotherapy associated with flexibility training does not increase the knee range of movement of healthy adults: systematic review and meta-analysis of randomized clinical trials

The stretching with thermotherapies associated have been related in the literature as a way to increase the range of motion (ROM), but still are not consensus about this efficacy and costeffectiveness. The muscle stretching is a useful technique in rehabilitation and in physical activities programs, either to gain or maintain the flexibility, as a recovery of musculoskeletal and joint injuries. Objective: To determine the effects of thermotherapies associated to flexibility training in ROM of knee extension in healthy adults. Method: The search strategy was conducted in main databases, as Cochrane Library, LILACS, PEDro, PUBMED/ Medline, Scopus and Web of Science. The searches were done in 2016, and renewed in 2023, in order to achieve new publications along this time. Were selected only randomized clinical trials that have executed a training of hamstrings stretching, associated or not with one or more thermotherapies in healthy young adults, as long as the outcome was knee extension ROM. Only papers in Portuguese or English were assessed. To evaluate risk of bias was used the Cochrane Collaboration's Risk of Bias Tool, and the methodological quality assessment was rated following the PEDro Scale. Results: Eight articles were included, totalizing 260 participants. The papers showed low methodological quality, and uncertain risk of bias. Only chronic effect of local warming and cryotherapy plus stretching showed a statistically significant difference versus control group. However, the thermotherapy action associated with stretching is still unclear, once the results suggest that even without the thermotherapy there are ROM increases. Conclusion: The stretching is effective in knee extension ROM improvement in healthy adults, with or without thermotherapy. New studies with higher methodological rigor and standardized protocols are needed

Os alongamentos com termoterapias associadas têm sido relatados na literatura como forma de aumentar a amplitude de movimento (ADM), mas ainda não há consenso sobre sua eficácia e custo-efetividade. O alongamento muscular é uma técnica útil na reabilitação e em programas de atividades físicas, tanto para ganho ou manutenção da flexibilidade, quanto para recuperação de lesões musculoesqueléticas e articulares. Objetivo: Determinar os efeitos das termoterapias associadas ao treinamento de flexibilidade na ADM de extensão do joelho em adultos saudáveis. Método: A estratégia de busca foi realizada nas principais bases de dados, como Cochrane Library, LILACS, PEDro, PUBMED/ MedLine, Scopus e Web of Science. As buscas foram realizadas em 2016, e renovadas em 2023, a fim de alcançar novas publicações ao longo deste tempo. Foram selecionados apenas ensaios clínicos randomizados que tenham executado um treinamento de alongamento de isquiotibiais, associado ou não a uma ou mais termoterapias, em adultos jovens saudáveis, desde que o desfecho fosse ADM de extensão de joelho. Apenas artigos em português ou inglês foram avaliados. Para avaliar o risco de viés foi usado o Risk of Bias Tool da Cochrane Collaboration, e a avaliação da qualidade metodológica foi classificada de acordo com a Escala PEDro. Resultados: Foram incluídos oito artigos, totalizando 260 participantes. Os artigos apresentaram baixa qualidade metodológica e risco incerto de viés. Apenas o efeito crônico de aquecimento local e crioterapia associados ao alongamento mostrou uma diferença estatisticamente significativa em relação ao grupo controle. No entanto, a ação da termoterapia associada ao alongamento ainda não está clara, uma vez que os resultados sugerem que mesmo sem a termoterapia há aumento da ADM. Conclusão: O alongamento é eficaz na melhora da ADM de extensão do joelho em adultos saudáveis, com ou sem termoterapia. Novos estudos com maior rigor metodológico e protocolos padronizados são necessários

Efeitos de um protocolo de aquecimento-alongamento-resfriamento sobre a flexibilidade muscular / Effects of a warm-up-cool-down protocol on muscle flexibility

Objetivo: Investigar os efeitos da associação entre alongamento e recursos termoterapêuticos sobre o ganho de flexibilidade e amplitude de movimento. Métodos: Este ensaio clínico, controlado, não randomizado e cego teve duração de três semanas, com duas sessões semanais e incluiu 27 indivíduos do sexo feminino, as quais compuseram tanto o grupo experimental quanto o controle, de forma que um de seus membros inferiores recebeu a intervenção terapêutica dos recursos termoterapêuticos e o membro oposto foi submetido apenas ao alongamento. A análise angular foi realizada através do software de avaliação postural Kinovera. Resultados: Os efeitos do alongamento associado ao calor prévio e resfriamento pós intervenção se mostraram mais eficazes comparado ao grupo controle pré-intervenção (p<0,000), grupo controle pós intervenção (p= 0,003) e grupo experimental pré-intervenção (p<0,000). Conclusão: A aplicação de calor prévio ao alongamento, seguido pelo emprego imediato de resfriamento propicia ganhos de flexibilidade muscular e amplitude de movimento maiores que o alongamento simples.

Objective: To investigate the effects between stretching and thermotherapeutics resources on gaining flexibility and range of motion. Methods: This controlled, non- randomized, blinded clinical trial lasted three weeks, with two weekly sessions and included 27 female individuals, who made up both the experimental and the control group, so one of their legs received therapeutic intervention from chemotherapeutic resources and the opposite one was submitted to stretching only. Angular analysis was performed using the Kinovera postural assessment software. Results: The effects of stretching associated with pre-intervention heat and post-intervention cooling were more effective compared to the pre-intervention control group (p<0.000), post- intervention control group (p= 0.003) and pre-intervention experimental group (p<0.000). Conclusion: The application of heat prior to stretching followed by immediate cooling provides gains in muscle flexibility and range of motion greater than simple stretching.

Abstract Objective To map the occupational safety measures recommended to professionals involved in the intraoperative care of patients undergoing Hyperthermic Intraperitoneal Chemotherapy. Methods Qualitative scoping review based on the Joanna Briggs Institute. Searches were performed in Pubmed, VHL, ScIELO, Scopus, Web of Science, Google Scholar, The Chocrane Library databases and gray literature. The PCC acronym was used in the research question: what occupational safety measures are necessary in the operating room for professionals working directly or indirectly in the intraoperative period of HIPEC? A search for articles published between 2015 and 2019 was performed. Results Literature on the subject was scarce. Ten articles were selected: a systematic review; two control cases; two descriptive studies; four literature review studies; an experience report. In the analysis of articles, the recommended safety measures for professionals who work directly or indirectly in this surgical procedure was evidenced, namely: education and training of the staff involved; use of individual and collective protective equipment; provision of infrastructure and general guidelines. Conclusion Recommended safety measures for professionals involved in the intraoperative care of patients undergoing Hyperthermic Intraperitoneal Chemotherapy are: team training; use of specific individual and collective protection equipment; necessary infrastructure, such as adjusting the air conditioning to higher pressure inside the operating room; and general guidelines regarding the organization of the operating room, waste disposal, cleaning of the room/materials used, and monitoring of the occupational health of the team involved in the surgical procedure.

Valor de la imagenología (TC y PET-TC) en el diagnóstico de la carcinomatosis peritoneal. Estudio preliminar / Diagnostic value of CT and Pet CT for detection of peritoneal carcinomatosis. Preliminary study / Valor das técnicas de imagem (TC y Pet-TC) no diagnóstico da carcinomatose peritoneal. Estudo preliminar

Resumen: En la evaluación de la carcinomatosis peritoneal (CP) la imagenología contribuye al diagnóstico preciso de compromiso peritoneal, aunque su eficacia es aún limitada. La tomografía computada (TC) es el estudio de imagen más utilizado y el PET-TC es cada vez más solicitado en la valoración de diferentes neoplasias. El objetivo del presente trabajo es evaluar el rendimiento de la TC y el PET-TC en el diagnóstico de CP en tumores digestivos y ginecológicos. Material y método: estudio retrospectivo, observacional, de 11 casos operados de CP en los que previamente se había realizado TC o PET-TC, o ambos. Se analizan los resultados de los estudios imagenológicos por separado y en conjunto, y se comparan con los hallazgos intraoperatorios y anatomopatológicos. Resultados: la TC fue concordante en 8 de 10 casos (S 78%, E 100%, VPP 100%, VPN 33%), mientras que el PET-TC lo fue en 9 de 11 pacientes (S 100%, VPP 81%). Al considerar en conjunto la TC y el PET-TC, la sensibilidad fue de 100% y el VPP de 82%. Conclusiones: en los resultados obtenidos se constata una subestimación de la CP en la imagenología a causa de las características de los nódulos y su patrón de captación. En el PET-TC, un SUV > 6 podría aumentar la probabilidad diagnóstica de carcinomatosis. Esta breve serie de casos permite sugerir que TC y el 18FGD PET-TC deben ser solicitados y analizados en forma conjunta para incrementar su rendimiento, aunque la exploración quirúrgica continúa siendo el método más eficaz para el diagnóstico y evaluación de la CP.

Summary: Imagenology contributes to the accurate diagnosis of peritoneal compromise in the assessment of peritoneal carcinomatosis, although its effectiveness is still limited. CT is the most frequently used study and PET/CT is graduallly more requested in the assessment of different neoplasms. This study aims to assess performance of CT and PET/CT for diagnosis of peritoneal carcinomatosis in digestive and gynecological tumours. Method: retrospective, observational study of 11 cases operated on peritoneal carcinomatosis after a CT and/or PET/CT had been performed. The results of both image studies were analysed separately and altogether and they were subsequently compared to intraoperative and pathology studies. Results: CT matched findings in 8 out of 10 cases (sensitivity 78%, specificity 100%, positive predictive value 100%, negative predictive value 33%), whereas PET/TC matched in 9 out of 11 patients (sensitivity 100%, PPV 81%). When considered together, sensitivity was 100% y el PPV de 82%. Conclusions: the results of the study confirm imagenology studies overestimate peritoneal carcinomatosis based on the characteristics of nodules and its uptake pattern. In CT/PET, SUV> 6 could increase the probability of diagnosing carcinomatosis. This small series of cases enables our suggesting CT and 18F-FDG PET-TC to be requested and analysed together to increase its efficiency, although surgical exploration continues to be the most effective method to diagnose and assess peritoneal carcinomatosis.

Resumo: Na avaliação da carcinomatose peritoneal (CP) as técnicas de imagem contribuem ao diagnóstico preciso do compromisso peritoneal, embora sua eficácia ainda seja limitada. A tomografia computadorizada (TC) é o estudo de imagens mais utilizado e a tomografia computadorizada por emissão de pósitrons (PET-TC) é cada vez mais solicitado na avaliação de diferentes neoplasias. O objetivo do presente trabalho, é avaliar o rendimento da TC e do PET-TC no diagnóstico de CP em tumores digestivos e ginecológicos. Material e método: estudo retrospectivo, observacional de 11 casos de carcinomatose peritoneal operados nos quais previamente se havia realizado TC e/ou PET-TC. Os resultados de ambos estudos foram estudados isoladamente e em conjunto e foram comparados com os achados intraoperatórios e histopatológicos. Resultados: a TC foi concordante em 8 de 10 casos (S 78%, E 100%, VPP 100%, VPN 33%), e o PET-TC em 9 de 11 pacientes (S 100%, VPP 81%). A sensibilidade foi de 100% e o VPP de 82% quando ambos estudos foram analisados conjuntamente. Conclusoes: observa-se nos resultados uma subestimação da CP nas técnicas de imagem, devido às características dos nódulos e seu padrão de captação. No PET-TC, um SUV > 6 poderia aumentar a probabilidade de diagnosticar carcinomatose. Esta breve série de casos permite sugerir que a TC e o 18FGD PET-TC devem ser solicitados e analisados em forma conjunta para aumentar o rendimento. No entanto a exploração cirúrgica continua sendo o método mais eficaz para o diagnóstico e avaliação da CP.

Quality of life in a phase 2 trial of short-course hyperthermic intraperitoneal chemotherapy (HIPEC) at interval debulking surgery for high tumor burden ovarian cancer / Avaliação da qualidade de vida em ensaio clínico de fase 2 envolvendo quimioterapia intraperitoneal hipertérmica (HIPEC) de curta duração no momento da citorredução de intervalo em pacientes com câncer de ovário de grande volume tumoral

ABSTRACT Introduction: to evaluate the effect of short-course (i.e.: 30 minutes) HIPEC on health-related quality of life (HRQoL) in our feasibility study; NCT02249013. Methods: a prespecified secondary end-point of our open-label, multicenter, single-arm, phase 2 trial on safety and efficacy was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30, version 3.0). Patients were required to complete the HRQoL questionnaire at baseline, after HIPEC, and after the end of the treatment. Changes of HRQoL over time were assessed by median scores for each domain and analyzed by Friedman`s test at a significant two-sided level of 0.05. Results: fifteen patients with high tumor burden EOC were recruited from our public health system between February 2015 and July 2019. A baseline EORTC QLQ-C30 questionnaire and at least one follow-up questionnaire was received from all of the patients. No significant difference over time in the QLQC30 summary scores was observed (p>0.05). The transitory impairment on patients HRQoL immediately after the short-course HIPEC trended to return to baseline at the end of the multimodal treatment. Conclusions: we found no significant impairment of short-course HIPEC on patients HRQoL into the context of our comprehensive treatment protocol.

RESUMO Objetivo: avaliar o impacto da quimioterapia intraperitoneal hipertérmica (HIPEC) de curta duração (i.e.: 30 minutos) na qualidade de vida (QoL) relacionada à saúde (HRQoL) no contexto de ensaio clínico terapêutico piloto; NCT02249013. Métodos: avaliou-se o desfecho secundário predeterminado de HRQoL em ensaio clínico de fase 2 de segurança e eficácia, aberto, multicêntrico, de braço único, utilizando-se o questionário European Organization for Research and Treatment of Cancer Quality of Life (EORTC QLQ-C30, versão 3.0). As pacientes foram solicitadas a responder o questionário de HRQoL antes do tratamento, após a HIPEC, e ao fim do tratamento interdisciplinar. As variações da HRQoL ao longo do tempo foram avaliadas pelas medianas dos escores de cada domínio e analisadas pelo teste de Friedman, considerando-se nível de significância estatística bicaudal de 5%. Resultados: quinze pacientes com câncer de ovário de grande volume tumoral foram recrutadas do sistema de saúde pública (i.e.: SUS) entre fevereiro de 2015 e julho 2019. Um questionário basal e pelo menos um questionário de acompanhamento foram coletados de todas as pacientes. Não se observou diferença significativa ao longo do tempo na HRQoL em nenhum dos domínios ou sintomas estudados (p> 0,05). O comprometimento transitório da HRQoL imediatamente após a HIPEC de curta duração tendeu a retornar à linha de base ao final do tratamento multimodal. Conclusões: não se observou impacto significativo da HIPEC de curta duração sobre a HRQoL no contexto deste protocolo de tratamento interdisciplinar.

Manejo del mesotelioma peritoneal maligno con citorreducción quirúrgica más quimioterapia hipertérmica intraperitoneal en el Instituto Nacional de Cancerología, Colombia: reporte de un caso y revisión bibliográfica / Peritoneal malignant mesothelioma treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy at the National Cancer Institute, Colombia: case report and literature review

El mesotelioma peritoneal es una neoplasia que se origina en las células mesoteliales del peritoneo. Histórica-mente, la supervivencia de los pacientes con mesotelioma peritoneal maligno sin tratamiento, es menor de 12 meses y se considera una neoplasia resistente a la quimioterapia. La citorreducción quirúrgica y la quimioterapia regional administrada como quimioterapia hipertérmica intraperitoneal (Hyperthermic Intraperitoneal Chemothe-rapy, HIPEC) se asocia con mejor supervivencia a largo plazo.Se presenta el caso de un paciente con antecedentes de exposición al asbesto y con diagnóstico de mesotelioma peritoneal maligno de tipo epitelioide, que fue tratado con cirugía citorreductora más quimioterapia hipertérmica intraperitoneal en el Instituto Nacional de Cancerología con una supervivencia de un año libre de enfermedad

Peritoneal mesothelioma is originated at the mesothelial cells of the peritoneum. Historically the survival of patients with this disease is less than 12 months without treatment and it is considered a neoplasm resistant to chemotherapy. Citorreductive surgery with hiperthermic intraperitoneal chemotherapy (HIPEC) is associated with an increased long-term survival. Here we present the case of a patient who had a past history of asbestos exposure and who was diagnosed with peritoneal mesothelioma of the epithelioid subtype. The patient was treated with cytoreductive surgery and HIPEC at the Instituto Nacional de Cancerología (Bogotá, Colombia) and has had a 12 month disease free survival

High-intensity focused ultrasound ablation as a treatment for benign thyroid diseases: the present and future

High-intensity focused ultrasound (HIFU) is a promising ablation technique for benign thyroid nodules. Current evidence has found good short- to medium-term outcomes, similar to those of better-established ablation techniques such as radiofrequency and laser ablation. The fact that it does not require insertion of a needle into the target makes HIFU a truly non-invasive treatment. Although it is not without risks, its low risk profile makes it an attractive alternative to surgery. There is much room for future development, starting from expanding the current indications to enhancing energy delivery. Relapsed Graves disease and papillary microcarcinoma are diseases that can benefit from HIFU treatment. Its role in the mediation of immune responses and synergistic effects with immunotherapy are promising in the fight against metastatic cancers.

Leishmaniasis cutánea y embarazo / Cutaneous leishmaniasis and pregnancy

Se estudió a una mujer de 19 años, con embarazo de cuatro meses, que presentaba cuatro úlceras cutáneas de tres meses de evolución, diagnosticadas por biopsia como leishmaniasis cutánea. El frotis directo y la leishmanina fueron negativos. Dado que todos los medicamentos usuales para la leishmaniasis cutánea están contraindicados en el embarazo, la paciente no recibió tratamiento, aunque curó espontáneamente durante el embarazo. Se cree que la leishmaniasis cutánea no tiene peligro para la mujer embarazada y que no hay transmisión de la madre al feto en el humano, aunque se ha detectado en animales en condiciones experimentales. La paciente tuvo un parto sin complicaciones y la condición de salud tanto de ella como de su hijo era normal a los dos años de seguimiento.

We studied a 19-year-old woman, with a 4-month pregnancy who presented with four cutaneous leg ulcers of three months of evolution diagnosed by biopsy as cutaneous leishmaniasis. Direct smear and the leishmanin skin test were negative. Since all the usual medications for cutaneous leishmaniasis are contraindicated in pregnancy, she did not receive any treatment but cured spontaneously of her lesions during pregnancy. It is believed that cutaneous leishmaniasis does not carry danger for pregnant women and that there is no maternal-fetal transmission in humans, though it occurs in experimental animals. The patient gave birth without complications and both she and her son remained normal after two years of follow-up.

Treatment of cutaneous leishmaniasis with thermotherapy in Brazil: an efficacy and safety study

Abstract: BACKGROUND: Pentavalent antimonials remain as the standard drugs in the treatment of cutaneous leishmaniosis. The high cost, difficult administration, long treatment time, toxicity and increasing morbidity are factors that limit the use of these drugs. OBJECTIVES: To describe the response to radiofrequency thermotherapy in the treatment of localized cutaneous leishmaniasis in Brazil, and to evaluate its safety and tolerability. METHODS: We conducted a non-comparative open trial with a total of 15 patients confirmed to have cutaneous leishmaniasis on parasitological examination. A single radiofrequency thermotherapy session at 50ºC for 30 seconds was applied to the lesion and its edges. In patients with more than one lesion, only the largest one was treated initially. If after 30 days there was no evidence of healing, the smaller lesion was also treated with thermotherapy. Clinical cure was defined as visible healing for three months after treatment. The patients were followed-up for six months and there was no follow-up loss. RESULTS: Of all 23 lesions, only two evolved to complete healing without the need of treatment. Of 21 lesions, 18 (85.7%) achieved full healing. The main observed side effects were itching, burning sensation, pain and blisters. STUDY LIMITATIONS: Sample with a small number of patients and short follow-up. CONCLUSION: Thermotherapy can be considered a therapeutic alternative in localized cutaneous leishmaniasis, especially in cases of single cutaneous lesions and with formal contraindications to conventional treatment with pentavalent antimonials.

The efficacy and safety of high-intensity focused ultrasound ablation of benign thyroid nodules

High-intensity focused ultrasound (HIFU) is a promising form of thermal ablation of benign thyroid nodules, but evidence supporting its use is scarce. The present review evaluated the efficacy and safety of single-session HIFU treatment of benign thyroid nodules. As reported in the literature, the extent of nodule shrinkage following treatment ranged from 48.8% to 68.8%. Like other forms of ablation, the shrinkage rate was greatest in the first 3-6 months, and the best responders were patients with small (≤10 mL) nodules. Complications were uncommon, but temporary vocal cord palsy occurred in 3%-4% of patients, and was related to the distance between the HIFU beam and the recurrent laryngeal nerve. Despite being safe and efficacious, a larger-scale prospective trial is required.

Effect of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy on relapse pattern in primary epithelial ovarian cancer: a propensity score based case-control study / 부인종양

OBJECTIVE: Hyperthermic intraperitoneal chemotherapy (HIPEC) has been proposed as a treatment in ovarian cancer. A recently published RCT demonstrated that HIPEC prolongs disease-free survival (DFS) and overall survival (OS) in ovarian cancer. The aim of the study was to investigate oncologic results of cytoreductive surgery+HIPEC compared with cytoreductive surgery alone in advanced primary ovarian cancer with a particular attention to the pattern of recurrence. METHODS: This is a retrospective case control study with a propensity score (PS) matching of the patients. All the patients treated for primary advanced ovarian cancer who underwent interval surgery with or without HIPEC were collected; a PS was calculated in order to match cases to controls. RESULTS: Among 77 eligible patients 56 patients were included in the study. Preoperative patients' characteristics were homogeneous. No difference in morbidity and mortality after surgery were recorded. DFS was not different among the 2 groups (13.2 vs. 13.9 months, p=0.454) but OS was better in patients treated with HIPEC with no median reached vs. 35.5 months (p=0.048). Patients treated with cytoreductive surgery alone were more likely to have a peritoneal recurrence (43% vs. 14%). CONCLUSION: HIPEC seems to affect the relapse pattern with lesser peritoneal recurrence. This difference in relapse pattern seems to affect the OS with better results in patients treated with HIPEC. Further studies are needed to confirm these findings.

A proposal of Brazilian Society of Surgical Oncology (BSSO/SBCO) for standardizing cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) procedures in Brazil: pseudomixoma peritonei, appendiceal tumors and malignant peritoneal mesothelioma / Proposta de padronização da Sociedade Brasileira de Cirurgia Oncológica (BSSO/SBCO) para procedimentos de citorredução cirúrgica (CRS) e quimioterapia intraperitoneal hipertérmica (HIPEC) no Brasil: pseudomixoma peritoneal, tumores do apêndice cecal e mesotelioma peritoneal maligno

ABSTRACT Cytoreductive surgery plus hypertermic intraperitoneal chemotherapy has emerged as a major comprehensive treatment of peritoneal malignancies and is currently the standard of care for appendiceal epithelial neoplasms and pseudomyxoma peritonei syndrome as well as malignant peritoneal mesothelioma. Unfortunately, there are some worldwide variations of the cytoreductive surgery and hypertermic intraperitoneal chemotherapy techniques since no single technique has so far demonstrated its superiority over the others. Therefore, standardization of practices might enhance better comparisons between outcomes. In these settings, the Brazilian Society of Surgical Oncology considered it important to present a proposal for standardizing cytoreductive surgery plus hypertermic intraperitoneal chemotherapy procedures in Brazil, with a special focus on producing homogeneous data for the developing Brazilian register for peritoneal surface malignancies.

RESUMO A cirurgia citorredutora com quimioterapia intraperitoneal hipertérmica emergiu como um importante tratamento das neoplasias peritoneais e é, atualmente, o padrão de atendimento para neoplasias epiteliais do apêndice associadas à síndrome de pseudomixoma peritoneal, bem como para o mesotelioma peritoneal maligno difuso. No mundo, existem algumas variações reconhecidas das técnicas de cirurgia citorredutora e quimioterapia intraperitoneal hipertérmica, entretanto nenhuma técnica até agora demonstrou sua superioridade sobre o outra. Portanto, a padronização destes procedimentos poderia melhorar a prática clínica e permitir a comparação adequada entre os resultados. Neste cenário, a Sociedade Brasileira de Cirurgia Oncológica considera importante a apresentação de uma proposta de padronização de procedimentos de cirurgia citorredutora com quimioterapia intraperitoneal hipertérmica no Brasil, com um foco especial na produção de dados homogêneos para o desenvolvimento do registro brasileiro das neoplasias peritoneais.

Clinical observation of intrapleural hyperthermic perfusion chemotherapy for patients with malignant pleural effusion caused by lung cancer / 国际肿瘤学杂志

Objective To observe the efficacy and adverse reaction of intrapleural hyperthermic perfusion and intrapleural chemotherapy for patients with malignant pleural effusion (MPE) caused by lung cancer.Methods A total of 103 patients with MPE caused by lung cancer were assigned into one of two groups:intrapleural hyperthermic perfusion group (n =65) and intrapleural chemotherapy group (n =38).The disease control rate,MPE progress free survival,the relationship between vascular endothelial growth factor (VEGF) concentration in pleural effusion and curative effect and adverse reactions were observed.Results The overall disease control rate in intrapleural hyperthermic perfusion group and intrapleural chemotherapy group was 81.5％ and 52.6％ respectively,with a significant difference (x2 =9.834,P =0.002).The median MPE progress free survival of the two groups was 3.10 and 2.15 months respectively,with a significant difference (x2 =10.512,P =0.001).A significant difference of the median MPE progress free survival was observed in low VEGF concentration subgroup between intrapleural hyperthermic perfusion and intrapleural chemotherapy (3.34 months vs.2.20 months;x2 =9.409,P =0.002),but no difference was observed in high VEGF expression subgroup (2.85 months vs.2.10 months;x2 =2.429,P =0.119).The main adverse reactions included gastrointestinal adverse reaction,fatigue and hematotoxicity.Fatigue occurred in intrapleural hyperthermic perfusion group more commonly compared with intrapleural chemotherapy group (67.7％ vs.13.2％;x2 =28.595,P ＜ 0.001).Conclusion Compared with intrapleural chemotherapy,intrapleural hyperthermic perfusion can better improve disease control rate and MPE progress free survival in MPE patients caused by lung cancer,and it's adverse reactions are tolerated easily.The MPE progress free survival prolonging is observed especially in VEGF low expression subgroup.VEGF level in pleural effusions maybe could predict efficacy of intrapleural hyperthermic perfusion.

Observation of the effect of hyperthermia combined with chemotherapy in patients with advanced gastric carcinoma / 中国基层医药

Objective To observe the therapeutic efficacy and security of hyperthermia combined with chem-otherapy for advanced gastric carcinoma.Methods The clinical data of 126 patients with advanced gastric cancer were retrospectively analyzed.According to the different treatment methods,they were divided into simple chemotherapy group(A group,63 cases)and chemotherapy combined with hyperthermia group (B group,63 cases).A group received chemotherapy through vein,the patients received docetaxel 75mg/m2 on day 1,tegafur 80mg/m2 on day 1 -14 and cisplatin 75mg/m2 on day 2 -4 of 21 -day courses.B group received hyperthermia together with chemothera-py.Hyperthermia was maintained at 40 -42℃ for 90min.The efficacy and toxicity -side -effect after the patients received two courses were evaluated.Results In A group,the rate of complete remission(CR)was 0 case,partial remission(PR)in 28 cases,stable disease(SD)in 27 cases,progressive disease(PD)in 8 cases,and the overall response rate(CR +PR)was 44.4%,while those in B group were 3 cases,36 cases,21 cases,3 cases and 61.9%, respectively.There was significant difference between the two groups(χ2 =4.589,P =0.032).The improvement rate of life quality of B group(58.7%)was better than A group(33.3%),there was statistically significant difference between the two groups(χ2 =9.232,P =0.002).The rates of Ⅲ°+Ⅳ°abnormal liver and kidney function,myelo-suppression and gastrointestinal tract in A group were 19.0%,23.8% and 25.4%,those in B group were 15.9%, 20.6% and 30.2%,there were no statistically significant differences between the two groups (P =0.815,P =0.830, P =0.426).Conclusion Hyperthermia combined with chemotherapy is efficient and safe for advanced gastric carci-noma,and it is worthy of furthermore study and observation in clinic.

Clinical observation of intrapleural hyperthermic perfusion chemotherapy for patients with malignant pleural effusion caused by lung cancer / 国际肿瘤学杂志

Objective To observe the efficacy and adverse reaction of intrapleural hyperthermic perfusion and intrapleural chemotherapy for patients with malignant pleural effusion (MPE) caused by lung cancer.Methods A total of 103 patients with MPE caused by lung cancer were assigned into one of two groups:intrapleural hyperthermic perfusion group (n =65) and intrapleural chemotherapy group (n =38).The disease control rate,MPE progress free survival,the relationship between vascular endothelial growth factor (VEGF) concentration in pleural effusion and curative effect and adverse reactions were observed.Results The overall disease control rate in intrapleural hyperthermic perfusion group and intrapleural chemotherapy group was 81.5％ and 52.6％ respectively,with a significant difference (x2 =9.834,P =0.002).The median MPE progress free survival of the two groups was 3.10 and 2.15 months respectively,with a significant difference (x2 =10.512,P =0.001).A significant difference of the median MPE progress free survival was observed in low VEGF concentration subgroup between intrapleural hyperthermic perfusion and intrapleural chemotherapy (3.34 months vs.2.20 months;x2 =9.409,P =0.002),but no difference was observed in high VEGF expression subgroup (2.85 months vs.2.10 months;x2 =2.429,P =0.119).The main adverse reactions included gastrointestinal adverse reaction,fatigue and hematotoxicity.Fatigue occurred in intrapleural hyperthermic perfusion group more commonly compared with intrapleural chemotherapy group (67.7％ vs.13.2％;x2 =28.595,P ＜ 0.001).Conclusion Compared with intrapleural chemotherapy,intrapleural hyperthermic perfusion can better improve disease control rate and MPE progress free survival in MPE patients caused by lung cancer,and it's adverse reactions are tolerated easily.The MPE progress free survival prolonging is observed especially in VEGF low expression subgroup.VEGF level in pleural effusions maybe could predict efficacy of intrapleural hyperthermic perfusion.

Modalidades Terapêuticas Alteram Limiar de Dor à Pressão de Indivíduos com PontosGatilho Miofasciais / Therapeutic Modalities Change Pressure Pain Threshold in Individuals with Myofascial Trigger Points

A fisioterapia dispõe de vários métodos analgésicos, entre eles a estimulação elétrica nervosa transcutânea (TENS) e o infravermelho terapêutico (IV), porém há dúvidas em relação a qual possua maior efeito e seja mais duradouro. O objetivo do estudo foi analisar o limiar de dor à pressão em indivíduos com ponto gatilho na região de músculo trapézio superior, tratados com recursos eletro e fototerapêuticos. Trinta indivíduos, que apresentavam ponto gatilho ativo na região do trapézio superior, foram randomizados em dois grupos: grupo tratado com TENS (GT) e grupo tratado com infravermelho (GIV). Para avaliar o limiar da dor à pressão foi utilizado um algômetro de pressão, ambos aplicados antes do tratamento, após 30 minutos, 24 e 48 horas; além disso, utilizou-se a escala visual analógica da dor. Para análise estatística foram utilizados testes específicos: teste t não pareado (para comparação entre grupos) e T-student pareado (para comparações intraperíodos), sendo adotado nível de significância de 5%. Observou-se que entre as modalidades terapêuticas estudadas, tanto a TENS quanto o infravermelho apresentaram aumento do limiar de dor à pressão logo após (30 minutos) da aplicação, porém o infravermelho apresentou uma manutenção da analgesia superior a TENS, quando analisado o limiar de dor à pressão.(AU)

Physiotherapy has several analgesic methods, including transcutaneous electrical nerve stimulation (TENS) and therapeutic infrared (IR), but there are doubts as to which has greater effect and is more durable. The aim of this study was to analyze the pressure pain threshold in individuals with trigger points in the upper trapezius muscle region treated with electro and phototherapeutic resources. Thirty (30) individuals with active trigger points in the upper trapezius region, were randomized into two groups: TENS (GT) and infrared (GIV) treated groups. To evaluate the pressure pain threshold, a pressure algometer was used, both applied before the treatment, after 30 minutes, 24 and 48 hours. In addition, the visual analogue pain scale was used. For statistical analysis, specific tests were used: unpaired t-test (for comparison between groups) and paired T-student (for intraperiod comparisons), adopting a significance level of 5%. It was observed that between the therapeutic modalities studied, both the TENS and the infrared presented increase of the pressure pain threshold rigth after (30 minutes) the application; however, the infrared presented a maintenance of the analgesia superior to TENS when analyzing the pressure pain threshold.

Pathophysiological features of rat hemorrhagic shock under high temperature conditions / 中华创伤杂志

Objective To investigate the pathophysiological features of rat hemorrhagic shock under high temperature conditions.Methods A total of 128 SD rats were assigned to high temperature group and normal temperature group according to the random number table,with 64 rats per group.Rats in high temperature group were pretreated at 342 for 12 h,and in normal temperature group were kept at 25℃.Hemorrhagic shock models in rats were produced by withdrawing 40％ of the total blood volume via the femoral artery.Parameters of the two groups were measured including blood electrolytes (Na +,K +),plasma osmotic pressure,liver function [aspartate aminotransferase (AST),alanine aminotransferase (ALT)],kidney function [creatinine (CREA)],arterial blood gases (pH,PO2 and PCO2) and cardiac function [heart rate (HR),cardiac output (CO),cardiac index (CI) and DO2].Animal survival time and survival rate were detected.Results Before shock,high temperature group versus normal temperature group showed higher detections of Na+ concentration [(142.3 ± 2.2) mmol/L:(139.1 ±1.5) mmol/L],plasma osmotic pressure [(304.8 ± 4.7) mmol/L:(300.0 ± 1.9) mmol/L],HR [(462 ±30) times/min:(402 ± 44) times/min],CO [(0.892 ± 0.190) L/min:(0.713 ± 0.090) L/min] and CI [(0.0030±0.0006)L·min-1 · cm-2:(0.0023 ±0.0002)L· min-1 · cm-2] (P＜0.05).After shock,normal temperature group showed further increased concentrations of Na + and K + and significantly enhanced AST,ALT and CREA compared to normal temperature group (P ＜ 0.05).After shock,CO,CI and DO2 in high temperature group were decreased by 63％,63％ and 69％ respectively compared to those before shock,but less decrease was observed in normal temperature group.Rat survival rate and survival time were significantly reduced in high temperature group compared to normal temperature group (P ＜ 0.05).Conclusion Pathophysiological changes of hemorrhagic shock in rats under high temperature are mainly manifested as impaired cardiac function,significantly increased concentrations of Na + and K + and significantly shortened survival time.
