[Impact of the Interdisciplinary Chronic Pain Rehabilitation Programme in patients with and without sleep disorders]. / Impacto del Programa de Rehabilitación Interdisciplinario de Dolor Crónico en pacientes sin y con trastornos del sueño.

INTRODUCTION: Sleep disorders and chronic pain are linked to each other bidirectionally. Both are related to affective disorders, fatigue, depression, anxiety and drug abuse, and have a significant effect on quality of life. The Interdisciplinary Pain Programme (IDP) aims to relieve the patients' pain and improve their functionality by incorporating healthy postural, sleep and nutritional habits, relaxation techniques, physical exercise and cognitive-behavioural mechanisms. PATIENTS AND METHODS: A retrospective, observational, cross-sectional study was conducted. A total of 323 patients with chronic pain who completed the IDP were examined. They were assessed at the beginning and at the end of the programme with pain, depression, quality of life and insomnia scales, and were then compared between groups with and without insomnia, that is, with an insomnia severity index (ISI) less than 15 versus greater than or equal to 15. Fifty-eight patients were studied by means of polysomnography. RESULTS: A significant improvement (p < 0.0001) in pain, depression and quality of life, as assessed by the visual analogue scale (VAS), the Beck inventory and the Short Form-36 (SF-36) questionnaire was observed in chronic pain patients with an ISI below 15 and in those with an ISI greater than or equal to 15. The results were superior in the group of patients with insomnia. The presence of a high apnoea and hypopnoea index and periodic lower limb movements in patients was not related to improvements on the Beck, SF-36, ISI and VAS scales. CONCLUSIONS: In conclusion, IDP benefits patients with chronic non-cancer-induced pain in several affected areas, in addition to pain, due to a comprehensive treatment. Polysomnography can help diagnose specific pathologies and individualise pharmacological treatment.

TITLE: Impacto del Programa de Rehabilitación Interdisciplinario de Dolor Crónico en pacientes sin y con trastornos del sueño.Introducción. Los trastornos del sueño y el dolor crónico están relacionados bidireccionalmente. Ambos están relacionados con trastornos afectivos, fatiga, depresión, ansiedad y abuso de fármacos, y afectan significativamente a la calidad de vida. El objetivo del Programa Interdisciplinario de Dolor (PRID) es aliviar el dolor del paciente y mejorar su funcionalidad a través de la incorporación de hábitos posturales, del sueño y nutricionales saludables, técnicas de relajación, ejercicio físico y mecanismos cognitivoconductuales. Pacientes y métodos. Se realizó un estudio retrospectivo, observacional y transversal. Se examinó a 323 pacientes con dolor crónico que completaron el PRID. Se les evaluó al principio y al final del programa con escalas de dolor, depresión, calidad de vida e insomnio, y se les comparó entre grupos con y sin insomnio ­índice de gravedad del insomnio (ISI) menor de 15 frente a mayor o igual a 15­. Se estudió a 58 pacientes con polisomnografía. Resultados. Se observó una mejoría significativa (p < 0,0001) del dolor, la depresión y la calidad de vida evaluados mediante la escala analógica visual (EVA), el inventario de Beck y el cuestionario Short Form-36 (SF-36), tanto en pacientes con dolor crónico con ISI menor de 15 como ISI mayor o igual a 15. Los resultados fueron superiores en el grupo de pacientes con insomnio. La presencia de un índice de apneas e hipopneas elevado y movimientos periódicos de los miembros inferiores en los pacientes no se relacionó con la mejoría de las escalas de Beck, SF-36, ISI y EVA. Conclusiones. En conclusión, el PRID beneficia a los pacientes con dolor crónico no oncológico en varias esferas afectadas, además del dolor, mediante un tratamiento integral. La polisomnografía puede ayudar a diagnosticar patologías específicas e individualizar el tratamiento farmacológico.

Liposuction-derived human fat used for vascular graft sodding contains endothelial cells and not mesothelial cells as the major cell type.

PURPOSE: Endothelial cell transplantation has been suggested as a method to improve the patency of prosthetic grafts used for vascular reconstruction. A major technical concern of all cell transplantation studies has been the purity of cells in the primary isolate used for subsequent transplantation. Accordingly we have evaluated the cellular constituents of liposuction-derived human fat with immunocytochemistry and scanning electron microscopy. METHODS: Samples of liposuction-derived human fat were processed for immunohistochemistry and subsequently stained for the presence of von Willebrand factor (vWF), alpha-smooth muscle cell actin, cytokeratin (peptide 18), and the endothelial cell-specific marker EN4. We also performed histochemistry studies on the cells derived from this fat after collagenase dispersion of the liposuction far. RESULTS: Immunohistochemistry revealed that 86.1% of the cells in intact, liposuction-derived fat express vWF, whereas 5.7% of the cells exhibited alpha-smooth muscle cell actin, and 1.0% expressed the mesothelial cell-related antigen, cytokeratin peptide 18. Expression of EN4 was found in 89.6% of the cells counted in intact far. After digestion of fat with collagenase and centrifugal separation of adipocytes from vascular and stromal cells, the expression of vWF, alpha-smooth muscle cell actin, and cytokeratin was 77.5%, 5.8%, and 2.1%, respectively. EN4 expression was observed in 74.6% of the isolated cells. Thus most cells present in liposuction-derived fat, even before tissue digestion and cell isolation, were characterized as endothelium. Although other cells common to mesodermally derived tissue were identified (e.g., adipocytes, smooth muscle cells, and mesothelium), they represented a minor fraction of the total cells present. On isolation, the number of cells expressing vWF- and EN4-specific antigens was less than that observed in intact fat. CONCLUSIONS: This finding suggests that a portion of cells reacting with antibodies in situ lose vWF and EN4 staining during the isolation procedure. Unlike omentum, liposuction-derived fat predominantly contains adipocytes and endothelial cells. On digestion of liposuction-derived fat and separation of cells, vascular endothelial cells represent the major cellular component.

[Noisy circulation syndrome. Study of 28 cases]. / El síndrome de la circulación ruidosa. Estudio en 28 casos.

Twenty eight subjects with noisy circulation sindrome (NCS) defined as cases at least, with 4 murmurs in different arteries were studied. They were divided in groups A, B, C formed by 9 normal children, 9 peripheral vascular atherosclerosis adults and 10 Takayasu's arteritis cases, respectively. In the whole population a complete chronometric arterial auscultation and in groups B and C an arteriography of at least 3 arteries with murmurs, were performed. Groups A, B and C had 40, 50 and 37 arterial murmurs, respectively, which were predominantly localized in supraortic trunks, pelvic and phemoral arteries, and supraortic and abdominal regions, respectively. 100, 19.1 and 21.1% of
