ABSTRACT Although technically simple, surgical correction of patent ductus arteriosus can have serious complications. In this context, acute ventricular failure must be remembered, as its prompt diagnosis and proper management can change clinical outcomes.

PURPOSE:To evaluate the healing of skin wounds induced experimentally in rats using a crystalline cellulose membrane (Veloderm(r)).METHODS:Thirty-two rats were divided into two groups: control group (CG) wounds treated with a solution of 0.9% sodium chloride and Veloderm(r) group (VG) wounds treated with a crystalline cellulose membrane. The rats were evaluated at different times over twenty-six days.RESULTS:Weight loss was observed in the animals from both groups in the early stages, with greater weight in the VG animals at the end. Times of predominant hypothermia, pink color of the wound in both groups over all time points, increased granulation tissue in the CG animals, the presence of slight oozing from the wound and feature in the VG animals, more serous exudation of the bloody feature, greater wound contraction and pain in the CG animals and an absence of pain and earlier complete wound healing in the VG rats were also observed.CONCLUSION:The crystalline cellulose membrane is effective in the treatment of wounds in rats, easy to use, protects and maintains the humidity of the wound, decreases pain, eases the visualization and control of the evolution of the lesion.

OBJETIVO: Avaliar o impacto dos sintomas depressivos e da dor neuropática na qualidade de vida (QV) de pacientes diabéticos com polineuropatia distal diabética (PNDD). MÉTODOS: Foram avaliados 204 pacientes com diabetes melito tipo 2. O diagnóstico de PNDD foi realizado por meio do Escore de Sintomas Neuropáticos e Escore de Comprometimento Neuropático. A gravidade da dor neuropática foi avaliada por meio da Escala Visual Analógica (EVA); os sintomas depressivos, por meio do Inventário Beck de Depressão (IBD); a QV, com o World Health Organization Quality of Life abreviado (WHOQOL-bref). RESULTADOS: Pacientes com PNDD apresentaram escores mais altos no IBD (12,6 ± 7,2 versus 9,9 ± 7,3; p = 0,018) e no EVA (5,0 ± 2,4 versus 2,6 ± 2,9, p < 0,001). Em relação à QV, apresentaram escores mais baixos no domínio físico (52,8 ± 15,5 versus 59,2 ± 17,0; p = 0,027) e ambiental (56,6 ± 12,3 versus 59,6 ± 13,6; p = 0,045). CONCLUSÕES: Pacientes diabéticos com PNDD apresentam pior QV nos domínios físico e ambiental do WHOQOL-bref, provavelmente devido à maior sintomatologia depressiva e gravidade de dor.

OBJECTIVE: To investigate the impact of depressive symptoms and neuropathic pain in the quality of life (QL) of diabetic patients with diabetic distal polyneuropathy (DDP). METHODS: Two hundred and four patients with type 2 diabetes mellitus were evaluated. The diagnosis of DDP was achieved using the Neuropathy Disability Score and Neuropathy Symptom Score questionnaires. The severity of neuropathic pain was assessed by means of a Visual Analogue Scale (VAS); the severity of depression, by means of the Beck Depression Inventory (BDI); and QL was assessed by means of the World Health Organization Quality of Life Instrument-bref (WHOQOLbref). RESULTS: Patients with DDP presented significant higher scores in BDI (12.6 ± 7.2 versus 9.9 ± 7.3; p = 0.018) and in VAS (5.0 ± 2.4 versus 2.6 ± 2.9; p < 0.001). They also presented significant lower scores in the physical (52.8 ± 15.5 versus 59.2 ± 17.0; p = 0.027) and environmental domains (56.6 ± 12.3 versus 59.6 ± 13.6; p = 0,045). CONCLUSIONS: Diabetic patients with DDP presented a worse QL in the physical and environmental domains of the WHOQOL-bref, probably due to more depressive symptoms and the severity of pain.
