OBJECTIVE To evaluate the effects of low-level laser therapy isolated and associated with Calendula officinalis oil in treating diabetic foot ulcers. METHOD An experimental, randomized, controlled, prospective, interventional clinical case study using a quantitative approach. The sample consisted of 32 diabetic patients of both genders. Participants were randomly divided into four groups. Doppler Ultrasound evaluation of the Ankle-Brachial Index, brief pain inventory and analog pain scale were performed at baseline and after 30 days. RESULTS Reduced pain was observed in the Low-level laser therapy and Low-level laser therapy associated with Essential Fatty Acids groups (p<0.01). Regarding the Ankle-Brachial Index and Doppler Ultrasound, all groups remained stable. By analyzing lesion area reduction, Low-level laser therapy associated with Essential fatty acids group showed a significance of p=0.0032, and the Low-level laser therapy group showed p=0.0428. CONCLUSION Low-level laser therapy, performed alone or associated with the Calendula officinalis oil was effective in relieving pain and accelerating the tissue repair process of diabetic foot.

PURPOSE:To evaluate the effects of the low-level laser therapy applying Laser on the tissue repair in ulcer carriers due to diabetes. METHODS:Sixteen type II diabetic patients, ulcer carriers in the lower limbs, participated in the research from which eight were in the control group and eight were submitted to the low-level laser therapy with a pulsed wave form, visible ray, wave length of 632.8 nm, mW peak power, (Laser -HTM). The application time was of 80 (4J/cm2 ) seconds. The application was punctual without contact (approximately 1mm of distance), the pen being held in a perpendicular position related to the wound, in equidistant points. There were 12 appointments, of which three were done weekly in alternated days. Photograph records and an application of the brief inventory of pain were done before and after 30 days of follow-up. RESULTS:There was a significant decrease in the size of the wound when compared to the control group (p<0.05). The pain was also reported as having an intense improvement in the treated group. CONCLUSION:The low-level laser treatment seems to be an efficient method, viable, painless and of low costs concerning the tissue repair ulcers in a diabetic foot.

PURPOSE:To analyze the effects of the low-level laser therapy in the acute myositis induced in rats. METHODS:Fifteen male Wistar rats (Rattus norvegicus) were randomly distributed into three categories: control group (C), induced Myositis without treament (MI) and treated induced myositis (MT), for the experimental period of seven days. The induction of the acute myositis was done with 1% acetic acid by intramuscular route. The rats belonging to the experimental group had daily treatment through the GaAs (gallium arsenide) laser, with 904,0 nm length, and 45 mW peak power, with 3J/cm 2 , applied for 5 minutes on the animals' right posterior limb. RESULTS:In the MT group there was a statistic significant decrease in the number of inflammatory cells, related to the MI group (p<0.05), increase in the fibroblastic proliferation, when compared to groups C and MI related to MT group (p<0.01) and statistic significant edema regression (p=0.0400) in the MT group. CONCLUSION:The low-level laser therapy was efficient in the reduction of the inflammatory process, increase of the fibroblastic proliferation and the reduction of the edema.

A Neuropatia diabética é uma complicação desenvolvida pelo diabetes, sendo responsável pela alta taxa de mobimortalidade devido ao surgimento de ulcerações nos pés, podendo ocasionar amputações. Tem impacto na saúde pública e no dispêndio de recursos com assistência. A terapia a laser de baixa intensidade (TLBI), tem comprovada atuação no processo de reparo tecidual, além de promover analgesia, minimizar o processo inflamatório e melhorar a circulação local. O objetivo desta pesquisa foi avaliar a dor e qualidade de vida de diabéticos com úlceras, submetidos a intervenção terapêutica no processo de reparo tecidual. Participaram 32 diabéticos com úlceras, em 4 grupos. Grupo 1 Controle; Grupo 2 óleo de Girassol, para os Grupos 3 e 4, submetidos à Terapia a laser de baixa intensidade, aplicou-se o protocolo: 658 nm, 30 mW, dose 4 J/cm², em 4 semanas. Para o Grupo 4 houve a associação da TLBI ao óleo de girassol. Dor e qualidade de vida foram analisadas por meio do Inventário breve de dor e escala visual analógica. Resultados demonstraram diferença estatística significativa entre os grupos, com p <0,05,observando-se que o Grupo Controle apresentou aumento na área da lesão, com aumento da dor e piora na qualidade de vida, o Grupo 2 apresentou estabilização na área das úlceras, sem alívio da dor e discreta melhora na qualidade de vida. Os grupos 3 e 4 apresentaram redução na área da úlcera, significativo alívio da dor p <0,05, e consequente melhora na qualidade de vida, sugerindo que a TLBI se apresente como uma importante estratégia terapêutica.

Diabetic neuropathy is a complication developed by diabetes, accounting for the high rate of mobi-mortality due to the emergence of foot ulcers and can lead to amputations. This impacts public health and the resources related to care expenditure. The low-level laser therapy (LLLT) has proven performance in the tissue repair process, and also promotes analgesia, reduces inflammation and improves local circulation. The objective of this study was pain and quality of life of diabetics with ulcers who underwent therapeutic intervention in the tissue repair process. 32 diabetics with ulcers participated in 4 groups. Control group 1; Group 2 Sunflower oil, for groups 3 and 4, undergoing laser therapy of low intensity, applied the protocol: 658 nm, 30 mW, dose 4 J / cm² over 4 weeks. Group 4 associated LLLT with sunflower oil. Pain and quality of life were assessed using the brief pain inventory and visual analog scale. Results showed statistically significant differences between the groups, with p <0.05. The control group showed an increase in the area of the lesion with increased pain and a poorer quality of life, Group 2 showed stabilization in the area of ulcers without pain relief and a slight improvement in quality of life. Groups 3 and 4 showed a reduction in ulcer area, significant pain relief (p <0.05), and consequent improvement in quality of life, suggesting that LLLT presents itself as an important ...

The thoracic esophageal perforations frequently complicate with fistula when submitted to primary suture. The use of autogenous tissues, like pleura, to reinforce the primary suture has proved to be useful in reduce the incidence of fistulas or at least the severity of the leaks in case they occur. The mortality has reduced too, consequently. A case of an extensive esophageal perforation is presented, where the use of pleural wrap to reinforce the esophagography was very important to contain the leak and to permit a good evolution of the patient.
